Description

Technical Field

[0001] This utility model relates to the field of steel truss assembly and construction technology, and in particular to a roof steel truss assembly anti-overturning support structure. Background Technology

[0002] Due to their large span and heavy weight, roof steel trusses are often constructed using segmented hoisting. Each steel truss segment is assembled one by one. During the segmented assembly process, anti-overturning supports need to be installed between adjacent steel trusses to prevent the steel trusses from tilting and collapsing. Conventional anti-overturning supports are often a combination of guy ropes, anti-overturning support rods, and other structures installed between the steel trusses. The anti-overturning support rods are directly welded and fixed to the steel trusses and to the supporting structure below the steel trusses. The anti-overturning support rods are removed after the segmented steel trusses are assembled. However, the removal of the anti-overturning support rods inevitably causes cutting damage to the steel trusses and the supporting structure below them, affecting the quality and aesthetics of the steel truss assembly. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An anti-overturning support structure for a roof steel truss assembly includes two steel trusses spaced apart, a support frame located below the ends of the steel trusses, and temporary anti-overturning supports located between the steel trusses. The anti-overturning supports include a horizontal beam between the two support frames and two diagonal support members respectively positioned between the horizontal beam and the two steel trusses. Both ends of the horizontal beam are fixedly connected to the upper parts of the two support frames. One end of each diagonal support member is hinged to the middle of the horizontal beam, and the other end is fixedly connected to the two steel trusses. Each end of the horizontal beam has a connector, which includes two clamping members in a Z-shape. Each clamping member includes a C-shaped clamp and a clamping plate located at the C-shaped clamp. The clamping plate has outward-folded fixing plates at both ends, with bolt holes on the fixing plates. Two clamping members are clamped onto the support frame with their openings facing each other. The two clamping members are connected and fixed by bolts passing through the fixing plates. The end of the crossbeam between the frames is welded and fixed to the first connector. The end of the support diagonal rod away from the crossbeam between the frames has a second connector. The second connector has the same structure as the first connector and is connected and fixed to the steel truss by bolts. The end of the support diagonal rod is hinged to the second connector. The support diagonal rod is a telescopic structure. The support diagonal rod includes a central threaded tube and screws one and two respectively located at both ends of the central threaded tube. The two ends of the central threaded tube have reverse threads, and screws one and two are threadedly connected to the two ends of the central threaded tube.

[0006] Furthermore, the supporting frame is a rectangular frame structure, and the supporting frame includes multiple standard sections, which are vertically stacked.

[0007] Furthermore, the standard section includes four columns and multiple frame web members located between two adjacent columns. The frame web members are horizontally welded and fixed between each group of two adjacent columns. Each column has a connecting steel plate at both ends. The middle of the connecting steel plate is welded and fixed to the end of the column. The connecting steel plate has multiple bolt holes. The connecting steel plates of adjacent standard sections are fixedly connected by bolts.

[0008] Furthermore, the steel truss includes an upper chord, a lower chord, and truss web members. The upper chord members are arranged parallel to each other above the lower chord members, and the truss web members are connected in multiple continuous N-shapes between the upper and lower chord members.

[0009] Furthermore, both steel trusses are provided with positioning steel short sections on opposite sides, and the positioning steel short sections are evenly spaced on the upper chord and the lower chord.

[0010] Furthermore, a connecting lug is provided in the middle of the crossbeam between the tire frames, and one end of each of the two supporting diagonal rods is hinged to the connecting lug via a pin.

[0011] Furthermore, the second connector is provided with a second connecting lug plate, and the end of the supporting diagonal rod is hinged to the second connecting lug plate by a pin.

[0012] Furthermore, guy ropes are installed on the outside of both steel trusses.

[0013] Compared with the prior art, this utility model has the following features and beneficial effects:

[0014] This utility model utilizes a temporary anti-overturning support installed between two steel trusses. The anti-overturning support includes a horizontal beam between two support frames and two diagonal support rods respectively positioned between the beam and the two steel trusses. This ensures stable assembly during the steel truss assembly process. Connectors are provided at both ends of the beam and at the end of the diagonal support rod furthest from the beam. Connectors 1 and 2 are bolted to the support frame and steel truss, respectively, facilitating subsequent disassembly and installation of the anti-overturning support and preventing damage to the support frame and steel truss during disassembly.
