PREFABRICATED CONSTRUCTION STRUCTURE, PREFABRICATED MAIN STRUCTURE, AND PREFABRICATED BUILDING

Description

TECHNICAL FIELD

The present disclosure relates to the technical field of construction engineering technologies, and in particular to a prefabricated construction structure, a prefabricated main structure, and a prefabricated building.

BACKGROUND

The prefabricated building means a building that is formed by prefabricating building components or combinations of components in the factories according to factory production, standardized design, modular construction, and other means, transporting the building components or the combinations of the components to sites, and assembling and mounting the building components or the combinations of the components. At present, some prefabricated buildings are mainly formed by splicing and enclosing a main structure with prefabricated plates. The overall strength of the main structure directly affects the stability of a completed building.

In related technologies, the main structure is formed by splicing metal pipes and multiple multi-directional joints. In order to ensure that the metal pipes and the multi-directional joints are connected firmly, the multi-directional joints and the metal pipes are sleeved with each other first, and then connected fixedly. In this connection method, the metal pipes are long, resulting in reduction of the overall strength of the main structure. That is to say, after the metal pipes are connected, a part of the metal pipes are overlapped with the multi-directional joints. This affects an overall span of the main structure, and wastes materials to some extent, resulting in an increase in production energy consumption. Further, due to sleeving, there are problems of connection loosening or difficulty in assembling caused by large or small tolerance during actual production and assembling, resulting in hidden danger and inconvenience to safety of use and operations.

Referring to FIG. 1 to FIG. 5, the present disclosure provides a prefabricated construction structure 100.

In an embodiment of the present disclosure, the prefabricated construction structure 100 is applied to a fixing rod 200. The fixing rod 200 includes a fixing steel pipe 210 and a fixing end plate 220 that is fixed to two opposite ends of the fixing steel pipe 210. The fixing end plate 220 is formed by machining steels, and is welded to the two opposite ends of the fixing steel pipe 210 using a welding process.

The prefabricated construction structure 100 includes a main I-beam 130, a first connection member 110, and a second connection member 120. The first connection member 110 includes at least one first connection I-beam 111 and a first connection end plate 112. One end of the first connection I-beam 111 is fixedly connected to the main I-beam 130, the first connection end plate 112 is connected to an end, away from the main I-beam 130, of the first connection I-beam 111, and the fixing end plate 220 is connected to the first connection end plate 112. The second connection member 120 includes at least one second connection I-beam 121 and a second connection end plate 122. An end of the second connection I-beam 121 is fixedly connected to the main I-beam 130 and forms an included angle with the first connection I-beam 111. The second connection end plate 122 is connected to an end, away from the main I-beam 130, of the second connection I-beam 121, and the fixing end plate 220 is connected to the second connection end plate 122.

Specifically, the main I-beam 130, the first connection I-beam 111 and the second connection I-beam 121 are all made of I-beam steels. In this way, overall structure strength is strong, and interchangeability and versatility are strong. That is, the main I-beam 130, the first connection I-beam 111 and the second connection I-beam 121 may be made by cutting different lengths of I-beams, to facilitate production and portability. The first connection I-beam 111 and the second connection I-beam 121 are connected to the main I-beam 130 at an angle of 90° or 180° based on actual construction requirements. It may be understood that the main I-beam 130 includes four connection surfaces in a horizontal direction. Therefore, a quantity of first connection I-beams 111 and second connection I-beams 121 is at most two. The first connection end plate 112 and the second connection end plate 122 are connected to the ends of the first connection I-beam 111 and the second connection I-beam 121 using a welding process.

During actual construction, there is an included angle between the first connection I-beam 111 and the second connection I-beam 121, the first connection I-beam 111 and the second connection I-beam 121 each have one end connected to the main I-beam 130 and the other end extending toward an end away from the main I-beam 130. The first connection end plate 112 and the second connection end plate 122 are fixedly connected at ends of the first connection I-beam 111 and the second connection I-beam 121, and the first connection end plate 112 and the second connection end plate 122 may be fixedly connected to a fixing end plate 220 of the fixing rod 200. In the present disclosure, the fixing rod 200 is fixedly connected to the ends of the first connection I-beam 111 and the second connection I-beam 121 separately via the fixing end plates 220. Because there is no overlap between the first connection I-beam and the second connection I-beam, an original length of the fixing rod 200 may be maintained. In addition, the overall construction span is increased, or the length of the fixing rod 200 is shortened on the basis of ensuring an original construction span, thereby reducing production costs and production energy consumption. Further, because the fixing rod 200 is directly connected to the main I-beam 130 via the first connection I-beam 111 and the second connection I-beam 121, the problems of connection loosening and difficulty in assembling caused by fabrication tolerance may be avoided to a greater extent. The strength of the connection between the fixing rod 200 and the main I-beam 130 is further improved, so that construction work is more convenient.

Referring to FIG. 6, in an embodiment of the present disclosure, the fixing end plate 220 is provided with a plurality of fixing holes 220a by machining. The first connection member 110 further includes a plurality of first connection parts (not shown in the figure), and the first connection end plate 112 is provided with a plurality of first connection holes 112a. The second connection member 120 further includes a plurality of second connection parts (not shown in the figure), and the second connection end plate 122 is provided with a plurality of second connection holes 122a. One first connection part penetrates through one first connection hole 112a and one fixing hole 220a, and one second connection part penetrates through one second connection hole 122a and one fixing hole 220a, to fixedly connect the first connection I-beam 111 and the second connection I-beam 121 to the main I-beam 130. It may be understood that the first connection part and the second connection part may be connection nuts or connection pins. Correspondingly, the first connection hole 112a, the second connection hole 122a, and the fixing hole 220a are threaded holes or pin holes. That is, the fixing rod 200 and the first connection I-beam 111, and the fixing rod 200 and the second connection I-beam 121 are detachable connection structures. This ensures stable connection and further facilitates construction.

Further, an end, away from the fixing steel pipe 210, of the fixing end plate 220 is convexly provided a positioning hole 220b. A first positioning post 1121 is disposed on the first connection end plate 112, a second positioning post is disposed on the second connection end plate 122, and a shape of the first positioning post 1121 and a shape of the second positioning post are the same. When being connected to the fixing rod 200, the first connection I-beam 111 and the second connection I-beam 121 may be embedded in the fixing hole 220a via the first positioning post 1121 and the second positioning post (not shown in the figure), thereby achieving pre-positioning effect. Therefore, connection is firmer while construction is conveniently performed and construction efficiency is improved.

Referring to FIG. 5 and FIG. 6, generally, the first connection I-beam 111 includes a waist plate 1111 and flanges 1112 that are connected to an upper side and a lower side of the waist plate 1111. When the first connection I-beam 111 is welded to the main I-beam 130, in order to implement strong stability of the connection and better adapt to different usage scenarios, breakage of a welding joint between the first connection I-beam 111 and the main I-beam 130 needs to be prevented. In an embodiment of the present disclosure, the prefabricated construction structure 100 further includes a positioning support member 140. The positioning support member 140 includes two support rib positions 1421. The positioning support member 140 is connected to the main I-beam 130 and the first connection I-beam 111, and the two support rib positions 1421 abut against opposite sides of two flanges 1112 of the first connection I-beam 111.

Specifically, the positioning support member 140 includes a connection plate 141 and two support plates 142 that are connected to two opposite sides of the two connection plates 141. The connection plate 141 and the two support plates 142 are formed by machining, welding, and splicing metal plates. Middle parts of the support plates 142 are tilted and concaved toward an inner side, to form two triangular support rib positions 1421. The connection plate 141 is connected to the middle of the support plate 142. The waist plate 1111 of the first connection I-beam 111 is provided with a first avoidance notch 111a, and a width of the first avoidance notch 111a is the same as a thickness of the connection plate 141. The connection plate 141 penetrates through the first avoidance notch 111a, and the two support rib positions 1421 abut against the two flanges 1112 of the first connection I-beam 111.

During actual construction, the positioning support member 140 may be welded to a preset position in advance. After the connection plate 141 is embedded in the first avoidance notch 111a, the two support rib positions 1421 respectively abut against the two flanges 1112 of the first connection I-beam 111 under the action of gravity, and the first connection I-beam 111 and the fixing rod 200 are welded and fixed via the positioning support member 140. It can be learned from the above construction that, due to the positioning support member 140, the fixing rod 200 is conveniently welded and fixed. That is, after the positioning support member 140 is welded to the first connection I-beam 111, because of lightweight, an end, having a heavy weight, of the fixing rod 200 is placed on the positioning support member 140. In this way, welding operations are performed more accurately, and labor is saved. In addition, the strength of the connection between the fixing rod 200 and the positioning support member 140 can be improved to a greater extent via the two support rib positions 1421 on the positioning support member 140.

Further, the positioning support member 140 further includes two attached weld plates 143. One attached weld plate 143 is connected to one support rib position 1421 in an integrated manner. The attached weld plates 143 abut against the two flanges 1112 of the first connection I-beam 111. In the present disclosure, a surface area of an attached weld plate 143 in a vertical direction is larger than that of the support rib position 1421. Therefore, the positioning support member 140 can more stably support the fixing rod 200. In addition, because a contact area is increased, the first connection I-beam 111 is more firmly connected to the fixing rod 200.

It should be noted that the positioning support member 140 may further be applied to the second connection I-beam 121. For a connection method and a connection structure, refer to the first connection I-beam 111, and details are not described herein again. A quantity and construction positions of the positioning support member 140 may be set based on actual needs, and are not specifically limited herein.

The prefabricated construction structure 100 includes a main I-beam 130, a first connection member 110, and a second connection member 120. The first connection member 110 includes at least one first connection I-beam 111 and a first connection end plate 112. One end of the first connection I-beam 111 is fixedly connected to the main I-beam 130, the first connection end plate 112 is connected to an end, away from the main I-beam 130, of the first connection I-beam 111, and the fixing end plate 220 is connected to the first connection end plate 112. The second connection member 120 includes at least one second connection I-beam 121 and a second connection end plate 122. An end of the second connection I-beam 121 is fixedly connected to the main I-beam 130 and forms an included angle with the first connection I-beam 111. The second connection end plate 122 is connected to an end, away from the main I-beam 130, of the second connection I-beam 121, and the fixing end plate 220 is connected to the second connection end plate 122.

Further, the fixing steel pipe 210 is provided with a plurality of threaded assembly holes along a length direction. The prefabricated main structure 1 includes a plurality of support beams 300. The support beams 300 are connected to an upper fixing steel pipe 210 and a lower fixing steel pipe 210 that are spaced apart via screws.
