Problems solved by technology

The rigidity of the single-shaped steel cantilevered steel is small. If the deflection increases when the cantilever is large, it will cause a large deformation of the bracket, so it can only be used in structures with small cantilevered structures; the steel wire rope in the cable-stayed cable is a flexible material, and the force is uneven. Or it is easy to...

Abstract

The invention discloses a construction method for an inclined tensioning reinforcing bar type and overhanging section steel scaffold. The construction method comprises the following steps that a load is borne in an inclined tension manner, one end of an inclined tensioning reinforcing bar is fixedly arranged on welded angle steel on the end part of overhanging section steel through a sleeve, the other end of the inclined tensioning reinforcing bar is connected onto a reinforcing bar pre-embedded in an upper structure through a sleeve, and the inclined tensioning reinforcing bar is used for bearing the load. According to the construction method, the most common materials are utilized, a scaffold can be erected in a short period, according to a series of structural measures, the requirement on bearing force and stability is met, and by fully utilizing the performance of current materials and greatly saving cost, an excellent construction effect and economic benefits are achieved.

Example Embodiment

[0013] Example 1
[0014] Such as figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 As shown, the construction method of steel cantilevered steel cantilever scaffolding is to pre-bury the embedded parts A and B in the floor 1 when concrete is poured on the floor where the steel support is located; when concrete is poured on the cable-stayed steel anchor floor, the cable-stayed steel bar is anchored. 3 Pre-embedded in the side beam 4; welded the ribbed double-angle steel 7 on the ground with the profiled steel beam, welded the rebar head 2 at the upper end, which is used to fix the scaffolding; hoisted the profiled steel beam to the floor 1 where the profiled steel support is located, one end Welding and fixing with embedded parts A and B; connect one end of the oblique-stretched steel bar 9 to the upper pre-embedded steel bar 6 with a sleeve I5, and insert the other end into the reserved double-angle steel hole 8 under the profile steel beam, and fix it with a sleeve II10. Preload.
[0015] A diagonal brace is set every 0.9m. Channel steel and angle steel are welded between each profile to form a longitudinal support and an X-shaped diagonal brace, so that the entire reinforced diagonal brace system forms a stable whole.
[0016] After the above procedures are completed, the formwork support is erected in accordance with the design requirements, in which the vertical steel pipe is inserted into the welded reinforcement joint at the upper end of the profile steel beam to fix the position. After the formwork support is erected, the concrete can be poured on the overhanging part of the roof panel.
