Description

Technical Field

[0001] This utility model relates to a support device for a steel structure space frame, belonging to the field of steel structure space frame construction technology. Background Technology

[0002] Bolted ball space frames are frequently used in building construction. A bolted ball space frame is a type of space frame structure that uses bolted connections, primarily composed of bolts, bolt balls, and space frame members. Compared to traditional welded structures, bolted ball space frames offer advantages such as simpler construction and easier component disassembly and replacement.

[0003] The utility model patent with patent number CN202321761818.6 discloses a bolt ball connection structure for a space frame member and a bolt ball. The connecting bolt is fully screwed into the bolt hole, which is an elongated hole extending in the left and right directions. The lower part of the tightening bolt is located on the right side of the left end of the elongated hole and abuts against it. A vertical groove is provided at the bottom of the inner wall of the sleeve. The connecting rod is vertically arranged, with its lower end located below the bottom of the sleeve, its middle part vertically movable through the bottom of the sleeve, and its upper end located in the vertical groove. A limiting groove is vertically arranged on the bottom side of the middle part of the connecting bolt, which is located on the vertical groove. A limiting block is arranged on the upper end of the connecting rod and located in the limiting groove, and is vertically movable relative to the limiting groove and the vertical groove. An elastic element is vertically arranged and located between the limiting block and the bottom surface of the vertical groove, and connects the two respectively.

[0004] While the aforementioned patent can achieve the fixation of the space frame crossbars and bolt balls, the current technology is not comprehensive and has the following drawbacks: 1. Traditional fixed bases cannot dynamically adjust the relative position of the bolt balls and the space frame crossbars, resulting in repeated adjustments to the node angles during assembly, leading to reduced construction efficiency. 2. It cannot further improve the stability of adjacent first and second bolt balls after assembly.

[0005] To solve one of the above problems, there is an urgent need for a support device for steel space frames. Utility Model Content

[0006] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to adjust the relative position of the second bolt ball and the crossbar of the space frame by adding a rotatable adjustable base A and a rotatable adjustable base B, so as to ensure the docking accuracy when the crossbar of the space frame is connected to the first bolt ball and the second bolt ball. To this end, a support device for steel space frame is provided.

[0007] The supporting device for the steel structure space frame of this utility model includes a bottom connecting plate A, on the upper surface of which a first bolt ball is installed via a reinforcing rib plate A. The device further includes a bottom connecting plate B, on the upper surface of which a second bolt ball is installed via a reinforcing rib plate B. A space frame crossbar is installed between the first and second bolt balls.

A space frame crossbar support assembly for supporting the space frame crossbar is installed between the rotatable adjustable base A and the rotatable adjustable base B.

[0008] By adding a rotatable adjustable base A and a rotatable adjustable base B, the bottom connecting plate A can rotate relative to the rotatable adjustable base A around its center line to adjust the relative position of the first bolt ball and the crossbar of the space frame. The bottom connecting plate B can rotate relative to the rotatable adjustable base B around its center line to adjust the relative position of the second bolt ball and the crossbar of the space frame, ensuring the docking accuracy when the crossbar of the space frame is connected to the first bolt ball and the second bolt ball.

[0009] In addition, by adding a crossbar support assembly, the crossbars of the space frame can be provided with auxiliary support. Through the synergistic effect of the rotatable adjustable base A and rotatable adjustable base B with the crossbars of the space frame, the crossbars of the space frame are tightened and limited, which improves the stability of the adjacent first bolt ball and second bolt ball after assembly, and makes the connection strength between the two adjacent sets of bolt balls stronger.

A space frame crossbar 10 is installed between the first bolt ball 1 and the second bolt ball 11. A rotatable adjustable base A is installed at the bottom of the bottom connecting plate A3, and a rotatable adjustable base B is installed at the bottom of the bottom connecting plate B13. A space frame crossbar support assembly for supporting the space frame crossbar 10 is installed between the rotatable adjustable base A and the rotatable adjustable base B.

[0037] By adding a rotatable adjustable base A and a rotatable adjustable base B, the bottom connecting plate A3 can rotate relative to the rotatable adjustable base A around its center line to adjust the relative position of the first bolt ball 1 and the space frame crossbar 10. The bottom connecting plate B13 can rotate relative to the rotatable adjustable base B around its center line to adjust the relative position of the second bolt ball 11 and the space frame crossbar 10, ensuring the alignment accuracy when the two ends of the space frame crossbar 10 are connected to the first bolt ball 1 and the second bolt ball 11, respectively.

[0038] In addition, by adding a crossbar support assembly, auxiliary support can be provided for the crossbar 10. Through the synergistic action of the rotatable adjustable base A and rotatable adjustable base B with the crossbar 10, the crossbar 10 is tightened and limited, improving the stability of the adjacent first bolt ball 1 and second bolt ball 11 after assembly. This results in stronger connection strength between adjacent sets of bolt balls. The structure is simple, easy to install and disassemble, low in cost, and has good stability. At the same time, the crossbar support assembly can be repeatedly disassembled and reassembled, shortening the construction cycle and reducing construction costs.
