Description

FIELD OF INVENTION

The present invention relates to the dome structures, which are suitable for the use in structures such as multi propose stadiums, doomed tents, etc.

BACKGROUND OF THE INVENTION

A dome structure is generally used for the dome of multi purpose stadiums and auditoriums will be having too many small elements such as screws, bolts, nuts and structure members, which results in increase of self weight momentum of the structure, complexity of assembling and instability because of number of joints. Present invention is to decrease the self-weight momentum, assembling complexity.

BRIEF SUMMARY OF THE INVENTION

- The objective of the present invention is to form a scalable and demountable dome/semi dome/arch surface structure without using any bolts or nuts or welding.
- This invention contains more stability, because of homogeneous curved connecting bars, which creates a continuous arch.
- Because of its self-threading alignment system the strength is almost equals to a single continuous connecting bar.
- This invention eliminates small aligning elements such as bolts, nuts and screws, which could cause safety issues in case of misalignments.
- This invention eliminates alignment complexity because of less number of joints.
- Because of homogeneous arch radius this structure overcomes the vertical self-weight momentum, and the horizontal self-weight momentum can be reduced by joining the arch with straight self threaded bars at deferent levels which are parallel to the surface plane.

DETAILED DESCRIPTION OF THE INVENTION

1. In this invention, Dome structure is constructed by, “Top connector” (TC) connecting to the “Base plates” (BP) by connecting the “Connecting arch's” (CA) and “Middle connectors” (MC), to form a meridian of a doom. “Middle connectors” (MC) are used to connect “Connecting arch's” (CA) to maintain a specific radius vertically for the entire structure, and to connect adjacent “Connecting arch's” (CA's) horizontally with horizontal bars, to maintain the stability of the structure at each horizontal level, as shown in FIG. 33. The “Middle connector's” are also used to attach another layer of similar dome structure to the structure or to attach accessories inside the structure.

Description of Parts in the Structure:

1. Top connector (“TC”):
- Top Connector is a self threaded circular bar with “n” number of homogeneous curved arch bars attached to it, at equal angles (360/n) as shown in FIG. 1. The threads on the circular bar at top and bottom can be used to connect another layer of dome or roof. The edge of the arch bar is self-threaded. The diameter of the circular bar and the diameter and the radius of the arch bars depend on the width and height of the desired dome and desired number of horizontal layers.
2. Connecting arch (“CA”)
- Connecting arch (all are same) is made up with round bars with predetermined diameter, bent to the radius equal to arch on “TC”. CA's are self-threaded at both ends (one side is external and the other side is internal) as shown in FIG. 2, so that it can form a desired meridian of a dome when connected together with “TC” and middle connector. The length of the arch depends on the width and height of the desired Dome and desired number of horizontal layers.
3. Middle connector (“MC”):
- Middle connectors (all are identical but deferent angle for each horizontal level) are made up by cutting the arch at a particular angle for each level, and attached two straight self threaded bars in middle of the arch, at a specified angle to the center of the plane, and parallel to the base plane. Two more straight self threaded bars attached at middle at perpendicular to the tangent plane at middle of arch as shown in FIG. 3.
4. Horizontal bars (“HB”):
- Horizontal bars are the round bars with self threaded at ends, one is right handed thread and another one is left handed thread (all are identical but deferent in lengths for each horizontal level) as shown in FIG. 4. These can be used to connect the middle connectors at each level.
5. Middle support (“MS”):
- Middle support is made up with a hallowed circular bar with a self threaded circular bar attached to it as shown in FIG. 5, and this can be used to connect middle support connector to the horizontal bar.
6. Middle support connector (“MSC”):
- Middle support connector consists of a part of connecting bar (CA) attached with a self threaded straight bar at a specified angle as shown in FIG. 6. These can be used to connect the “CA” to the straight bars and increase the number of arch (CA), so that the structure will have more stability.
7. Base plates (BP”):
- Base plate (BP) consists of a part of the connecting bar “CA” with self threaded on one end, and the other end is attached to solid plate (with four holes for the purpose of bolting) as shown in FIG. 7. Once all the base plates are connected the structure will be stable and can be bolted to pre arranged bolts.
8. Center connector (“CC”):
- Center connector “CC” is a circular bar with self threads at ends, one is right handed thread and another one is left handed thread as shown in FIG. 34. This can be used to add another layer of dome by connecting another “TC” to it.
- Then another dome structure can be built in the same way.
9. Layer connector (“LC”):
- Layer connector (LC) is a circular bar with self-threads at the ends, one is left thread and another one is right thread as shown in FIG. 35. This can be used to two middle connector of each dome layer.
