TECHNICAL FIELD

The invention relates to a formwork table element comprising:

• • p at least one formwork panel,
  • at least one longitudinal beam and several cross beams, which support the at least one formwork panel.

BACKGROUND AND SUMMARY

Furthermore, the invention relates to a formwork table comprising:

a formwork table element,

• • at least one formwork prop with a support element and with a prop head.

Finally, the invention relates to a method of constructing a slab formwork.

As described in EP 1 538 278 A2, for concreting a floor slab of a concrete structure, an essentially horizontally arranged formlining can be created, the edges of which are delimited by bulkhead formwork. In the prior art, it was already known to form the formlining using a large number of formwork panels that are placed on cross beams, which in turn are placed perpendicularly on longitudinal or yoke beams. The yoke beams are supported by floor props to the subfloor. In this state of the art, the load was transferred from the formlining via a structure of superimposed transverse and yoke beams in two layers. In contrast, EP 1 538 278 A2 refers to prefabricated formwork units consisting of formwork panels, cross beams and yoke beams, which can be moved between floors in a time-saving manner. Wooden cross beams are attached to the back of the formwork panels. Steel longitudinal beams and yoke beams extend below the cross beams. Connecting links are welded to the U-profiles of the yoke beams to attach the cross beams to the longitudinal beams. The supports can be attached to these yoke beams. For this purpose, holes are provided at regular intervals along the longitudinal and yoke beams to which the prop head holders can be attached using bolts. The prop heads are designed as swivel heads with which the supports can be swiveled to the side. A disadvantage, however, is that the longitudinal beams or yoke beams are arranged close to the longitudinal edges of the form board, which means that the floor props cannot be mounted on the longitudinal beams in many applications where space is limited, for example when concreting projecting concrete elements such as balcony slabs. With this state of the art, this problem had to be circumvented at great expense with intermediate beams, which were arranged under the longitudinal beams or yoke beams and parallel to the cross beams. However, this results in a supporting structure with three layers, which are formed by the cross beams, the longitudinal or yoke beams and the intermediate beams. This supporting structure is not only complex to set up, but also results in a very high structure, which is disadvantageous for many applications.

FR 3 027 932 A1 shows another pre-assembled formwork table in which the yoke and cross beams are arranged one above the other in two layers. In this state of the art, the ceiling supports are connected to the yoke beams. The cross beams can be connected to the yoke beams at different longitudinal positions. Individual holes can be used to adjust the yoke beams together with the supports and heads in relation to the cross beams. This allows the statics of the structure to be influenced. However, the operating effort is high. In addition, this prior art does not offer the desired variability. In contrast, the present invention has the task of alleviating or eliminating at least individual disadvantages of the prior art. The preferred aim of the invention is to extend the possible uses of formwork tables of the same type.

This task is solved by a formwork table element according to claim 1, a formwork table according to claim 10 and a method according to claim 15. Preferred embodiments are given in the dependent claims.

According to the invention, the at least one longitudinal beam and the plurality of cross beams are arranged overlapping in the direction perpendicular to the main layer of extension of the formwork panel (i.e. when the formwork panel is aligned horizontally in the vertical direction), wherein the at least one longitudinal beam and the plurality of cross beams each comprise connecting elements for connection to a prop head of a formwork prop.

In contrast to the prior art, the at least one longitudinal beam and the cross beams are not arranged entirely on top of each other, but overlapping, i.e. at least in sections at the same height. Thus, the cross beams cross the at least one longitudinal beam, preferably essentially at right angles. The at least one longitudinal beam and the cross beams form a supporting structure for the formwork panel. Preferably, the cross beams are permanently connected to the at least one longitudinal beam, for example via welded connections. Connecting elements for connecting formwork props are provided both on the at least one longitudinal beam and on the cross beams. Advantageously, individual formwork props can therefore be optionally mounted on the longitudinal beam and/or on the cross beams. This variability can be used, for example, to offset the formwork prop in relation to an outlet in the contact area. Furthermore, the static requirements can be precisely adjusted. For example, the formwork table element can be specifically supported with additional formwork props in areas of larger concrete accumulations, such as ceiling offsets. It is also advantageous for limited contact areas and when concreting projecting ceiling elements, such as balcony slabs, that the formwork props can be optionally mounted on the longitudinal and/or cross beams. Another advantage is that the construction height can be reduced compared to the state of the art due to the overlapping arrangement of the longitudinal and cross beams. In view of the reduced loading volume, transportation is also made easier.

For the purposes of this disclosure, the location and directional information refers to the intended state of use of the formwork table element with horizontal alignment of the formwork panel. Of course, the formwork panel can also be arranged inclined to the horizontal, in which case the location and direction information is to be transferred accordingly.

Depending on the embodiment, the formwork panel can be connected to the longitudinal and/or cross beams via a riveted, screwed or bonded connection.

For effective dissipation of the concrete forces, it is favorable if the preferably essentially flat upper sides of the longitudinal and cross beams are each arranged essentially in the same layer parallel to the main layer of extension of the formwork panel. The underside of the formwork panel is preferably in contact with the upper sides, i.e. the sides facing the formwork panel, of the at least one longitudinal beam and the several cross beams.

For connecting identical formwork props, it is favorable if the connecting elements of the at least one longitudinal beam are arranged at a first distance from the preferably essentially plane underside of the at least one longitudinal beam and the connecting elements of the cross beams are arranged at a second distance from the preferably essentially plane undersides of the plurality of cross beams, the first and second distances being essentially identical. The first and second distances refer to the distance perpendicular to the main layer of extension of the formwork panel, i.e. to the vertical distances when the formwork panel is oriented horizontally. In this embodiment, the undersides of the longitudinal and cross beams can each be designed as support surfaces for the prop head of the formwork prop. Thanks to the identical distances from the undersides to the connection openings, the same formwork prop can be connected to either the longitudinal beam or one of the cross beams, even in an embodiment in which the longitudinal beam and the cross beams are of different heights, i.e. comprise different extensions perpendicular to the main layer of extension of the formwork panel. When using a telescopic prop as a formwork prop in this design, the telescopic prop can be extended to different lengths depending on whether the telescopic prop is connected to the longitudinal beam or to one of the cross beams. Essentially, the same formwork prop can be used regardless of whether it is attached to the longitudinal beam and/or to one of the cross beams.

In a preferred embodiment, the at least one longitudinal beam and the multiple cross beams each comprise identical connecting elements for connecting to the prop head of the formwork prop. Advantageously, in this embodiment, the same formwork prop can optionally be connected to a longitudinal beam and/or cross beam.

For the variable, safe and simple connection of formwork props to the formwork table element, it is advantageous if connection openings, in particular passage openings, are provided as connecting elements of the longitudinal and/or cross beams. In this embodiment, at least one longitudinal beam and several cross beams are provided on the rear side of the formwork panel, preferably each with connection openings, which are set up for connecting formwork props. In order to reversibly and detachably connect a formwork prop to the formwork table element at the desired position, the connector of the prop head, depending on the design, is connected directly or via a connecting element, in particular via a connection pin, to at least one of the connection openings of one of the longitudinal and/or cross beams. When the formwork prop is mounted on the longitudinal or cross beam, the prop head is fixed in position relative to the formwork table element.

Preferably, the connection openings are designed as passage openings that pass completely through the longitudinal and cross beams transversely to their longitudinal direction. The opening is designed to receive, in particular to insert, a connecting element, in particular a connection pin, with which the connector of the prop head can be brought into engagement.

Alternatively, the connection openings can be designed as connecting grooves in the longitudinal and cross beams.

An element other than the formwork prop can also be connected to one of the connection openings, for example a railing adapter or a platform.

Preferably, the at least one longitudinal beam and the cross beam each comprise at least 3, preferably at least 5, in particular at least 10, connection openings, in particular passage openings which are preferably arranged at equal distances along the respective longitudinal or cross beam.

In a preferred embodiment, the formwork table element comprises a surrounding frame with two longitudinal and two transverse frame parts which border all sides of the at least one formwork panel, which is preferably essentially rectangular in plan view, depending on the embodiment exactly one formwork panel or an arrangement of several adjacent formwork panels.

Preferably, the longitudinal beam and/or the cross beams and/or the surrounding frame are made of metal, in particular steel. The formwork panel preferably comprises a panel element, in particular made of wood and/or plastic. The outer side of the formwork panel is designed as a formwork plane, which delimits the space to be filled with concrete. The panel element is preferably reversibly detachably connected to the surrounding frame.

The longitudinal and cross beams are preferably permanently connected to the longitudinal and transverse frame parts of the surrounding frame.

In order to ensure the desired stiffening on the one hand and to create a variety of connection options for formwork props on the other, the at least one longitudinal beam extends from one transverse frame part to the other transverse frame part of the surrounding frame. Preferably, at least two longitudinal beams, in particular exactly two longitudinal beams, are provided, which are arranged in particular parallel to each other and parallel to the longitudinal frame parts.

In order to create connection possibilities for formwork props, in particular also in a central area of the formwork table element, in relation to the two longitudinal sides of the formwork panel, it is favorable if at least two cross beams, preferably more than four cross beams, in particular more than six cross beams, are each provided with connection openings for the prop head between the two transverse frame parts, the cross beams each extending from one longitudinal frame part to the other longitudinal frame part. Preferably, the cross beams are arranged parallel to each other and parallel to the transverse frame parts of the surrounding frame.

In a preferred embodiment, at least one formwork prop is mounted on one of the longitudinal beams and/or cross beams. It is particularly preferred if a formwork prop is mounted at a crossing point of one of the cross beams with one of the longitudinal beams.

In order to be able to use a plurality of identical formwork props with the same length or, in the case of a telescopic prop, in the same extension position for supporting the formwork table element, it is advantageous if the longitudinal and cross beams each comprise essentially the same height and/or the same width. The height refers to the extension in the direction perpendicular to the main extension or panel plane of the formwork panel. The width refers in each case to the extension in the direction perpendicular to the longitudinal direction of the longitudinal or cross beams parallel to the main extension or panel plane of the formwork panel. In this embodiment, the undersides of the longitudinal and cross beams are preferably arranged essentially in the same layer parallel to the formlining.

In a preferred embodiment, the connecting elements, in particular the connection openings (relative to their centers), are arranged essentially at the same height, i.e. in the same layer parallel to the concrete-facing outer side, i.e. the formlining, the formwork panel.

Preferably, the longitudinal and cross beams each comprise a height of at least 70 mm, in particular of at least 80 mm, preferably of 90 mm to 110 mm and/or a width of at least 40 mm, in particular of at least 50 mm, preferably of 60 mm to 70 mm.

The formwork table according to the invention comprises the formwork table element in one of the embodiments described above and at least one formwork prop, preferably several, in particular identical, formwork props, wherein the prop head of the at least one formwork prop comprises at least one connector for connection to one of the connecting elements of the longitudinal and cross beams. Depending on the application, for example, at least two, in particular at least three, preferably at least four, formwork props may be provided, each of which is connected to one of the longitudinal and/or cross beams.

The support element of the formwork prop is preferably designed as a length-adjustable telescopic element, in particular with an inner part, preferably an inner tube, and with an outer part, in particular an outer tube. In the support setting for concreting the concrete element, the longitudinal axis of the support element is preferably essentially vertical.

In many applications of the formwork table, for example as a balcony table, it is favorable if at least one formwork prop is connected to one of the cross beams. It is preferable if several formwork props are connected to several cross beams, which are spaced apart in the longitudinal direction of the formwork table element. It is particularly preferred if a plurality of formwork props are each connected to several cross beams, i.e. a pair of formwork props or more than two formwork props are connected to each of several cross beams.

In a preferred embodiment, at least one connection pin is provided, which connects the at least one connector of the prop head to the connecting element of the longitudinal or cross beam.

The connector preferably comprises at least one hook element with a hook opening. Preferably, the connector comprises two hook elements, which are designed to grip the ends of the connection pin that protrude through the connection opening. Preferably, the connector comprises two hook connectors, each with two hook elements. One of the two hook elements is hooked onto the projecting ends of the connection pin. The other two hook elements are hooked onto the projecting ends of another connection pin, which is inserted through another of the connection openings.

Alternatively, at least one bracket element with an all-round closed bracket opening can be provided as a connector.

In a preferred embodiment, the prop head comprises a mounting comprising the connector and a head section connected to the support element, wherein the head section is pivotably connected to the mounting via a hinged connection, in particular between an upright, preferably essentially vertical, support setting and at least one horizontal transport setting. In this embodiment, the prop head is designed as a swivel head with which the support element can be swiveled to the side.

In a preferred embodiment, a locking arrangement is provided for optionally blocking and releasing the swivel of the head section relative to the mounting of the prop head, in particular in the upright support setting and in the horizontal transport setting. The locking arrangement may comprise a locking lever. The locking lever may comprise a locking lug which engages behind a retaining pin of the head section in the support setting. The locking lever can comprise an additional locking lug with which the formwork prop is locked in the horizontal transport setting, preferably by engaging with a further retaining pin of the head section.

In a preferred embodiment, the hinged connection of the prop head is designed in such a way that the support element extends along the cross beam in the horizontal transport setting when the formwork prop is mounted on one of the cross beams and/or that the support element extends along the longitudinal beam in the horizontal transport setting when the formwork prop is mounted on one of the longitudinal beams. For this purpose, the hinged connection may comprise a hinge axis which, in relation to the assembled state of the formwork prop, extends perpendicular to the longitudinal direction of the longitudinal or cross beam. Preferably, the hinged connection allows swiveling exclusively about the hinge axis transverse to the longitudinal direction of the longitudinal or cross beam.

For reversibly detachable assembly of the formwork prop, the support element comprises a head plate in a preferred embodiment, which is detachably connected to the prop head, in particular by means of a wedge element.

DETAILED DESCRIPTION

FIG. 1 shows a formwork table 1 for concreting a floor element. The formwork table 1 comprises a formwork table element 2, which is supported on several formwork props 3, four in the example shown. The number of formwork props 3 can be varied depending on the application. The formwork table element 2 has a surrounding frame 4, which supports at least one rectangular formwork panel 5 comprising a coating for contact with the concrete, at least on the upper side. The surrounding frame 4 is composed of two transverse frame parts 6 and two longitudinal frame parts 7, which form a rectangular frame for the formwork panel 5. For this purpose, the longitudinal frame parts 7 and the transverse frame parts 6 comprise upright frame lugs which border the inside of the formwork panel 5. The transverse frame parts 6 form the shorter transverse sides of the formwork table element 2. The longitudinal frame parts 7 form the longer longitudinal sides of the formwork table element 2. For example, the transverse frame parts 6 may comprise a length of from 0.5 meters (m) to 4.0 m, in particular from 1.5 m to 3.0 m, and the longitudinal frame parts may comprise a length of from 1.0 m to 10 m, in particular from 2.5 m to 7.0 m. In the embodiment shown, the formwork table element 2 comprises two longitudinal beams 8 between the two longitudinal frame parts 7. The longitudinal beams 8 extend over the length of the formwork table element 2 from the inside of one transverse frame part 6 to the inside of the other transverse frame part 6. In addition, several cross beams 9 are provided between the two transverse frame parts 6. The cross beams 9 extend across the width of the formwork table element 2 from the inside of one longitudinal frame part 7 to the inside of the other longitudinal frame part 7, the cross beams 9 being interrupted in each case at the intersections with the longitudinal beams 8. In the embodiment example shown, the longitudinal beams 8 and the cross beams 9 each comprise essentially the same height, i.e. extend perpendicular to the formwork panel 5, and essentially the same width, i.e. extend perpendicular to the longitudinal direction of the respective longitudinal beam 8 or cross beam 9 parallel to the main extension or panel plane of the formwork panel 5. In the example shown, the longitudinal beams 8 are designed as single profiles and the cross beams 9 are designed as double profiles. The surrounding frame 4, the longitudinal beams 8 and the cross beams 9 are fixed in position relative to each other. In this way, the surrounding frame 4, the longitudinal beams 8 and the cross beams 9 form a rigid support or stiffening structure for the formwork panel 5.

As can be seen from FIG. 1, the longitudinal beams 8 and the cross beams 9, viewed in the direction perpendicular to the formwork panel 5, are arranged overlapping, in the example shown at the same height. In the example shown, the undersides of the longitudinal beams 8 facing away from the formwork panel 5 and the undersides of the cross beams 9 facing away from the formwork panel 5 are arranged essentially at the same distance from the formwork plane of the formwork panel 5, seen perpendicular to the main layer of extension of the formwork panel 5, i.e. in the arrangement shown in the vertical direction. In the example shown, the undersides of the transverse frame parts 6 and the undersides of the longitudinal frame parts 7 are also arranged at the same height as the undersides of the longitudinal 8 and cross beams 9.

According to the invention, both the longitudinal beams 8 and the cross beams 9 each comprise connecting elements 10, each of which is configured to be connected to a prop head 11 of the formwork prop 3. Thus, formwork props 3 can be connected at different points of the supporting structure consisting of the longitudinal beams 8 and the cross beams 9.

A plurality of connection openings 12 are provided as connecting elements 10 of the longitudinal beams 8 and cross beams 9, which are distributed at a distance from one another along the longitudinal beams 8 and cross beams 9. In the embodiment example shown, the connection openings 12 are arranged at the same height, i.e. the centers of the connection openings 12 are arranged in the same layer parallel to the main layer of extension of the formwork panel 5. In the example shown, individual passage openings are provided as connection openings 12. The passage openings can, for example, have a circular cross-section or be designed as pear-shaped slit openings.

As can be seen from FIG. 1 and FIG. 3 and in detail from FIG. 7 and FIG. 8, the prop head 11 in the example shown is designed as a swivel head with a mounting 13 and a head section 14, which are connected to each other via a hinged connection 15 with a hinge axis 16. In the assembled state, the mounting 13 is immovably attached, in this case to one of the longitudinal beams 8. For this purpose, the mounting 13 comprises two connectors 17, which in the example shown are designed as pairs of hook connectors. During assembly, a connection pin 18 is inserted through the connection openings 12 and, in the embodiment shown, secured against slipping out of the connection openings 12 by at least one securing element, in particular a securing cotter pin. Subsequently, the first pair of hook connectors is brought into engagement with the ends of the connection pin 18 projecting laterally from the longitudinal beam 8. Subsequently, the hook openings of the second pair of hook connectors are aligned with another of the connection openings 12. A further connection pin 18 is inserted through the further one of the connection openings 12 and the hook openings of the second pair of hook connectors. As a result, the mounting 13 of the prop head 11 is held via the two connection pins 18 at two adjacent connection openings 12 of the longitudinal beam 8 and blocked against movement in all directions.

The hinged connection 15 can be used to swivel the formwork prop 3 from the support setting shown in FIG. 1 and FIG. 7 to the transport setting shown in FIG. 3 and FIG. 8. For this purpose, a locking arrangement 19 is actuated, which blocks the head section 14 in the support setting against swiveling in the direction of the transport setting. In the example shown, the locking arrangement 19 comprises a locking lever 20 with a locking lug 21 which, in the support setting, engages behind a retaining pin 22A of the head section 14, so that swiveling of the head section 14 about the hinge axis 16 is blocked. In the example shown, the mounting 13 also comprises a bearing element 23, in this case a bearing bolt or a bearing screw, which is accommodated in a recess 24 of the head section 14 in the support setting. The locking lever 20 is pivotably mounted on the mounting 13 about a pivot axis 25, in this case of the bearing element 23. By lifting the locking lever 20, the engagement of the locking lug 21 with the retaining pin 22A is released, as a result of which the head section 14 together with the support element 26 attached thereto can be pivoted, in particular by more than 45°, preferably by more than 60°. In the example shown, the locking lever 20 comprises an additional locking lug 27 which, in the horizontal transport setting, engages with a further retaining pin 22B of the head section 14, so that the head section 14 is secured against swiveling back into the upright support setting. In the example shown, the locking lever 20 comprises a locking protrusion 33, with which the further retaining pin 22B can be locked in a further horizontal transport setting (not shown), which is pivoted further than the horizontal transport setting relative to the support setting. For example, the horizontal transport setting can be achieved by swiveling by essentially 80° relative to the support setting and the further horizontal transport setting can be achieved by swiveling by essentially 90° relative to the support setting. To move from the (further) horizontal transport setting to the support setting, the formwork prop 3 is lifted slightly, the locking lever 20 is pulled out and the formwork prop is pivoted into the upright support setting and locked in place.

The support element 26 comprises a head plate 28 (not visible here), which is reversibly detachably connected to the head section 14 of the prop head 11 by means of a wedge element 29, in this case a double wedge.

FIG. 2 shows the use of the formwork table 1 for concreting a horizontal floor element, in this case a balcony slab. In the example shown, the formwork table 1 is set up on a lower balcony slab 30 below the balcony slab to be concreted. Due to the limited space available in this application, the formwork props 3 cannot be arranged below the outer of the two longitudinal beams 8, which extends further out than the free longitudinal edge of the lower balcony slab 30. The formwork table 1 according to the invention now makes it possible to connect individual formwork props 3 to the cross beams 9, which are arranged at the same height as the longitudinal beams 8, but extend transversely to them. This means that the transversely extending cross beams 9 can be used for attaching formwork props 3, which previously had to be arranged on their own intermediate beams, but which disadvantageously increased the overall height of the stiffening structure below the formwork panel 5. FIG. 2 also shows inclined props 32, which are used to absorb horizontal loads occurring during concreting.

FIG. 3 shows the formwork table 1 being lifted from a concrete ceiling (here with parapet on the edge of the ceiling) using hoisting gear 31, in this case a table fork. The formwork props 3 are arranged in the transport setting, in which the formwork props 3 are folded in at a flat angle, which prevents the formwork table 1 from colliding with the building.

FIGS. 4 to 6 illustrate the variable arrangements of the formwork or floor props 3 on the stiffening structure, which is formed by the longitudinal beams 8 and cross beams 9.

In the example shown in FIG. 4, two formwork props 3 are arranged on each of the longitudinal beams 8. The formwork props 3 are folded into the horizontal transport setting, in which the elongated support elements 26 of the formwork props 3 each extend along the longitudinal beam 8 on which the respective formwork prop 3 is mounted. In this configuration, the hinge axis 16 of the hinged connection 15 of the prop head 11 extends perpendicular to the longitudinal direction of the straight longitudinal beam 8 when the formwork prop 3 is mounted on the longitudinal beam 8. As a result, the head section 14 with the support element 26 is pivoted in a layer perpendicular to the cross beams 9. In the example shown, two formwork props 3 are mounted at a distance from each other on the longitudinal beams 8 in the longitudinal direction of the formwork table element 2.

In the example shown in FIG. 5, two formwork props 3 are each arranged on two cross beams 9 spaced apart in the longitudinal direction of the formwork table element 2. The formwork props 3 are folded into the horizontal transport setting, in which the elongated support elements 26 of the formwork props 3 each extend along the cross beam 9 on which the respective formwork prop 3 is mounted. When the formwork prop 3 is mounted on the cross beam 9, the hinge axis 16 of the hinged connection 15 of the prop head 11 extends perpendicular to the longitudinal direction of the cross beam 9 extending in a straight line. As a result, the head section 14 with the support element 26 is pivoted in a layer perpendicular to the longitudinal beams 8. In the example shown, two formwork props 3 are mounted on the cross beams 9 at a distance from each other in the transverse direction of the formwork table element 2. One of the formwork props 3 is mounted between the two longitudinal beams 8 on the cross beams 9. The other formwork props 3 are mounted at the intersections of the cross beams 9 with the longitudinal beams 8. As a result, the first pair of hook connectors is arranged on one side of the longitudinal beam 8 and the second pair of hook connectors on the other side of the longitudinal beam 8. This arrangement is statically particularly favorable.

In the example shown in FIG. 6, two formwork props 3 are mounted on two cross beams 9 and two formwork props 3 are mounted on one of the two longitudinal beams 8.

FIG. 9 schematically shows another embodiment in which the longitudinal beam 8 and the cross beam 9 are of different heights. However, the centers of the connection openings 12 are equidistant from the undersides of the longitudinal beam 8 and the cross beam 9, so that the same prop heads 11 can be used.
