Problems solved by technology
However, there is a problem with this installation method: before the transverse trusses are in place, the installed longitudinal trusses have very poor out-of-plane stability due to the lack of transverse trusses to stabilize them, and are prone to out-of-plane instability Phenomenon

Embodiment Construction
[0049] like Figure 1 to Figure 8 As shown, it is a temporary control method for the stability outside the installation surface of a fabricated steel truss of the present invention, comprising the following steps:
[0050](a) Calculate the angle between two adjacent longitudinal trusses, and determine the position of the specific out-of-plane stability control point on the longitudinal truss, and then determine the angle between the initial adjustment tie rod device and the longitudinal truss.
[0051] (b) Manufacture of truss locking device 1:
[0052] ① Connect the half U-shaped locking plate 11 and the connecting plate 14 into a whole by welding.
[0053] ② Weld the stiffening plate 12 on the outer surface of the half U-shaped locking plate 11.
[0054] ③Weld and fix the bottom plate 13 on the half U-shaped locking plate 11 and the stiffening plate 12.
[0055] (c) Production of the final adjustment device 3:
[0056] ① Determine the angle between the final adjustment d...

The invention discloses a temporary control method of surface external stability of fabricated steel truss mounting. The temporary control method comprises the following steps that (a) the included angle of two adjacent longitudinal trusses is calculated, and the positions of surface external stability control points on the longitudinal trusses are determined; (b) a truss locking device is manufactured; (c) a final adjustment device is manufactured, (d) a preliminary adjustment tie bar device is manufactured; (e) the truss locking device is mounted; (f) the longitudinal trusses are mounted in position; (g) assembly of the preliminary adjustment tie bar device is completed on the ground; (h) the preliminary adjustment tie bar device is subjected to upper-air preliminary in-position; and (i) the final adjustment device is adjusted. According to the temporary control method of surface external stability of fabricated steel truss mounting, the two longitudinal trusses are connected into a whole, so that the lateral integral rigidity capable of being resistant to surface external instability of the longitudinal trusses is formed; and the effect of surface external temporary stability can be provided for the longitudinal trusses of two different angles, the application range is wide, meanwhile environmental-friendliness steel is adopted, repeated utilization can be achieved, the principle is clear, implementation and operation are easy, control is easy, and promotion is easy.
Description
technical field [0001] The invention relates to the technical field of construction of fabricated steel truss building structures, and specifically relates to a temporary control method for stability outside the installation surface of fabricated steel trusses. Background technique [0002] At present, the prefabricated steel truss building structure is developing rapidly. Many airports, stations, stadiums and other buildings have widely used this type of structure. This type of structure usually has a large span and can meet the space requirements of building functions. It is mainly composed of longitudinal trusses and transverse trusses, and multiple transverse trusses are often designed between two longitudinal trusses. The commonly used installation method is: first install the two longitudinal trusses, and then install the transverse trusses between the two longitudinal trusses, and complete the installation of the overall structure in sequence according to the construc...
