Embodiment 1

[0025] Such as figure 2 As shown, first make a triangular tire frame. The size of the triangular tire frame is 2.7m high, 4m wide, 12m long, and 6m apart; use theodolite and level to recheck its axis and elevation, and pre-assemble the main components in the assembly site. Put the projection line, and install the detachable triangular tire frame.

[0026] Such as image 3 As shown, four No. 1 main pipes 7 in the horizontal direction are first installed on the tire frame, and the four No. 1 main pipes 7 are all perpendicular to the steel beam 4, parallel to each other and arranged at equal intervals.

[0027] Such as Figure 4 As shown, the No. 1 main pipe 7 is welded to the No. 2 main pipe 13, and the No. 2 main pipe 13 is connected between every two adjacent parallel No. 1 main pipes 7 as the base surface.

[0028] Such as Figure 4 As shown, the No. 3 main pipe 8 and the No. 4 main pipe 9 are welded into a ladder shape through the connecting plate, and are temporarily f...

Abstract

The invention provides a detachable triangular scaffold and a steel truss assembly construction method. The scaffold is of a triangular connected structure, and comprises main vertical rods, bottom cross rods, top steel beams, connecting plates, diagonal rods, bolts and the like. The rods are connected by the bolts in a positioning manner, and positioning holes are reserved at the top of each steel beam and used for controlling the axis position of a steel truss. The detachable triangular scaffold is capable of achieving on-site repeated assembling of ultrahigh ultra-wide steel members, and can be widely applied to the field of steel structure assembly construction.

Description

technical field [0001] The invention relates to a construction method for assembling a detachable triangular tire frame and a steel truss, and belongs to the technical field of steel structure engineering. Background technique [0002] The assembly of steel trusses belongs to high-altitude operations. During the construction process, high-altitude positioning and assembly is difficult. At present, the assembly work is mainly carried out by erecting overall scaffolding or fixing support frames. However, for some ultra-wide and ultra-high steel structures that require on-site assembly, there is often no suitable In particular, there are fewer tire frames that can be reused, which will undoubtedly increase the amount of steel used in the project, increase the construction difficulty of the project, increase the assembly period, delay the overall construction progress, and increase the construction cost of the project . Contents of the invention [0003] The invention provide...
