However, the patent still has certain shortcomings in the actual application process. Since the patent requires the setting of upper and lower inserts on the truss structure, and the conventional truss structure does not have additional space for setting a plug-in structure at the connection, the truss needs to be disassembled and then set. This operation method undoubtedly greatly increases the workload of the staff and is not convenient for directly reinforcing the existing trusses, resulting in a narrow actual scope of application of the patent.

[0030] Through the coordinated use of the upper chord 1, the lower chord 2, the web 3, the connection assembly 400 and the reinforcement assembly 500, it is possible to facilitate the stable reinforcement of conventional existing trusses, so that the reinforced structure can be applied to conventional trusses, greatly expanding the scope of applicability. At the same time, it also has extremely strong stability, can play an effective auxiliary support and reinforcement role, and reduces the workload and work difficulty of the construction staff, thereby effectively improving the practicality of the truss reinforcement structure.
[0031] In this embodiment, the reinforcement assembly 500 is a structure used to reinforce the truss.
[0032] like Figure 1 , Figure 2 and Figure 3As shown, the reinforcement assembly 500 includes two main support rods 501 abutting between the opposite sides of the corresponding upper chord rod 1 and the lower chord rod 2, two fixing plates 502 are fixedly connected to the left and right sides of the main support rods 501, a connecting plate 503 is fixedly connected to the side of the fixing plate 502 away from the corresponding main support rod 501, a triangular plate 504 is fixedly connected to the side of the fixing plate 502 away from the corresponding main support rod 501, two first bolts 505 are passed through the opposite sides of the top and bottom connecting plates 503, a secondary support rod 506 is fixedly connected between the opposite sides of the two diagonally distributed connecting plates 503, a second bolt 507 is passed between the front sides of the two secondary support rods 506, and a locking nut 508 is threadedly connected to the outer side of the second bolt 507.

Specifically, the inner wall thickness of the main support rods 501 is fifteen millimeters, which can play a stable reinforcement role for the connection between the upper chord rods 1 and the upper chord rods 1 and the connection between the lower chord rods 2 and the lower chord rods 2.
[0034] In addition, the top of the top connecting plate 503 is in contact with the bottom of the corresponding upper chord 1, and the bottom of the bottom connecting plate 503 is in contact with the top of the corresponding lower chord 2, so that the connecting plate 503 can be installed normally, and the opposite sides of the top and bottom triangular plates 504 are fixedly connected to the opposite sides of the top and bottom connecting plates 503 respectively, so that the triangular plates 504 can reinforce the corresponding fixed plates 502 and the connecting plates 503, thereby preventing the main support rod 501 from tipping over and deflecting through the auxiliary cooperation of the four triangular plates 504.

[0041] See also Figure 1-3 The present application also provides a technical solution: a steel truss, comprising a truss reinforcement structure provided in any of the above technical solutions and a steel connection structure composed of multiple groups of upper chords 1, lower chords 2, connection assemblies 400 and reinforcement assemblies 500.
[0042] The working principle of the above embodiment is:
[0043] When reinforcing the truss, first measure the distance between the upper chord 1 and the lower chord 2 on the opposite side, so as to manufacture the main support rod 501 and the corresponding secondary support rod 506 with matching height, weld the fixing plate 502 to the outside of the main support rod 501, move the two main support rods 501 to the upper and lower sides of the corresponding upper chord 1 and lower chord 2, and then fine-tune the positions of the two main support rods 501 so that the two main support rods 501 are symmetrically distributed on the left and right, and respectively connect the top and bottom connecting plates 503 to the bottom of the corresponding upper chord 1 and the top of the lower chord 2 through the first bolt 505. Fixed connection, the two auxiliary support rods 506 are respectively welded between the opposite sides of the two diagonally distributed connecting plates 503 in a front-to-back order, so that the opposite sides of the two auxiliary support rods 506 are fitted together, and the two auxiliary support rods 506 form an X shape, and a through hole is opened between the front sides of the two auxiliary support rods 506, and the second bolt 507 is passed through the through hole, and the locking nut 508 is threadedly connected to the outer side of the second bolt 507, so that the two auxiliary support rods 506 are connected together, and the upper chord rod 1 and the lower chord rod 2 can be reinforced and stabilized by the two main support rods 501 and the two auxiliary support rods 506.
