[0003] For the existing - technology roof steel truss assembly jig, its publication number is CN214134683U. As a limiting mechanism, it uses two jig units symmetrically arranged and connected to the top steel beam through a connecting plate; long circular holes for installing first bolts are provided on the connecting plate; L - shaped connecting plates are connected to the webs at both ends of the top steel beam through third bolts, circular holes are provided on the web of the top steel beam, and long circular holes are provided on the L - shaped connecting plates; circular holes are provided on the other side plate of the L - shaped connecting plate, and this side plate is connected to the column through a second bolt. This structure forms a triangular assembly jig, which is mainly used for the assembly and welding of the overall roof steel truss system. Although these are sufficient for use, there are still some problems. For example, during the disassembly process of this device, multiple screw rods need to be disassembled, which is rather troublesome. Therefore, a roof steel truss assembly jig for solving the above problems is proposed. Summary of the Utility Model

Detailed implementation manners

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0022] This application provides a roof steel truss assembly jig, which is mainly used to solve how to quickly install and disassemble the steel truss, and provides the following technical solutions, which will be described in detail below in combination with Figures 1-5 for a detailed description:

[0023] A roof steel truss assembly jig includes a first mounting bracket 1 and a second mounting bracket 2. A first vertical beam 3 is installed on the side of the first mounting bracket 1, and a second vertical beam 4 is installed on the side of the second mounting bracket 2. A fixing mechanism 5 is provided between the first vertical beam 3 and the second vertical beam 4. The fixing mechanism 5 is used to fix the first vertical beam 3 and the second vertical beam 4 together. Its specific components are: including first connecting rods 501 symmetrically fixed on the side of the first vertical beam 3. A second connecting rod 502 is fixed at the end of the first connecting rod 501. A movable plate 503 is fixed at the end of the second connecting rod 502 away from the first connecting rod 501. An inclined surface is formed at the end of the movable plate 503 away from the second connecting rod 502. A connecting cavity is formed on the inner wall of the second vertical beam 4. The first connecting rod 501 is slidably connected to the inner side wall of the connecting cavity. A limiting plate 504 is arranged on the top surface of the second connecting rod 502. A driving mechanism 10 is arranged at the top end of the limiting plate 504. The driving mechanism 10 is used to drive the limiting plate 504 to move up and down. Its specific components are: including a connecting groove 1002 formed on the inner top wall of the connecting cavity, and a spring 1001 is installed on the inner bottom wall of the connecting groove 1002. One end of the spring 1001 away from the connecting groove 1002 is fixedly connected to the limiting plate 504.

[0024] During the working process, the staff can fit the first mounting bracket 1 and the second mounting bracket 2 together. At this time, the movable plate 503 will gradually move towards the inner wall of the connecting cavity, and will contact the limiting plate 504, causing the limiting plate 504 to move upward. At this time, the spring 1001 is in a compressed state until the movable plate 503 disengages from the limiting plate 504. At this time, the spring 1001 will return to its natural state, driving the limiting plate 504 to move towards the second connecting rod 502, (such as Figure 4As shown in the figure, the first vertical beam 3 and the second vertical beam 4 are fixedly clamped together in this way, which is simple and convenient and does not require welding of the first vertical beam 3 and the second vertical beam 4.

[0025] As Figure 1 , Figure 3 and Figure 4 As shown in the figure, in some embodiments, a first connecting plate 6 is fixedly provided on one side of the outer wall of the limiting plate 504. Rectangular holes are symmetrically formed on the outer wall of the second vertical beam 4. One end of the first connecting plate 6 away from the limiting plate 504 penetrates through the rectangular hole and a second connecting plate 7 is fixedly provided at the end. More specifically, the staff can pull the second connecting plate 7 upward, thereby driving the first connecting plate 6 and the limiting plate 504 to move upward, so that the limiting plate 504 is located inside the connecting groove 1002, and then pulling the first vertical beam 3 and the second vertical beam 4 can separate the first mounting bracket 1 and the second mounting bracket 2.

[0026] As Figure 1 and Figure 3 As shown in the figure, in some embodiments, the material of the spring 1001 is stainless steel. More specifically, stainless steel material has high durability and strength, can maintain the performance of the spring 1001 for a long time, and is not prone to deformation or damage.

[0027] As As Figure 1 and Figure 2 As shown in the figure, in some embodiments, connection holes are formed on the outer walls of both the first vertical beam 3 and the second vertical beam 4. A screw 8 is provided on the inner wall of the connection hole. The screw 8 movably penetrates through the connection hole. Nuts 9 are threadedly connected to both ends of the screw 8. The diameter of the nut 9 is larger than the diameter of the connection hole. Anti-slip strips are annularly arranged on the outer wall of the nut 9. More specifically, the staff can penetrate the screw 8 through the connection hole, and then put the nut 9 on the outer wall of the screw 8, and move the nut 9 in the direction of the anti-slip strips, so as to further clamp the first vertical beam 3 and the second vertical beam 4.

[0028] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
