Problems solved by technology

[0005] However, the problems in this invention application are: the processing of the hemmed U-shaped steel plate arranged at the end of the wall is difficult, which is not conducive to industrial production, the production efficiency is low, and the cost is pushed up; the steel structure is exposed, and fireproof coating must be adopted, which not only increases cost, and how to coordinate the wall section with the concrete wall is also very troublesome; the embodiment only has "line-shaped" shear walls, and how to solve "T-shaped" and "L-shaped" shear walls must be quite difficult. Therefore, it is difficult for the invention application to be practicable
[0010] Most of the existing steel-concrete shear wall edge members and construction technologies use steel to enhance the performance of the shear wall structure, and there is no use of steel as both the reinforcement of the edge members of the shear wall and as an enhancement of the shear wall structure. At the same time, it can also be used as a fixing part without dismantling the formwork to achieve a multi-purpose effect, so as to improve the level of building industrialization and open up an implementation mode of high-efficiency and low-consumption prefabricated concrete shear wall structure buildings.

[0065] Example 2: Using thin-walled steel trusses 4 to construct edge members of concrete shear walls

[0066] Such as Figure 21 to Figure 23 As shown, when the shear wall connecting beam is connected with the edge member, the use of open square steel pipe 1 will affect the reinforcement arrangement of the shear wall connecting beam. In this case, the thin-walled steel truss 4 is used to construct the edge member of the concrete shear wall ,

[0067] Step 1. Arranging thin-walled steel trusses 4 and binding steel bars

[0068] The thin-walled steel trusses 4 of the edge members of the shear wall are arranged according to the area of ​​the longitudinal force-bearing reinforcement required by the structural design, and the connection between the upper and lower sides of the thin-walled steel trusses 4 can be made of small-section thin-walled steel trusses. 4. Welding or bolting after inserting, it is also possible to add additional steel bars at the joint to realize the lap j...

Embodiment 3

[0074] Embodiment three, the construction process of shear wall body

[0075] Such as Figure 18 to Figure 20 As shown, the concrete shear wall body is constructed with thin-walled steel trusses 4,

[0076] Step 1. Arranging thin-walled steel trusses 4 and binding steel bars

[0077] According to the area of ​​vertically distributed steel bars in the shear wall body that needs to be set in structural design, the thin-walled steel trusses 4 of the shear wall body are arranged according to the principle of equal strength, and the connection between the upper and lower sides of the thin-walled steel trusses 4 can be small The cross-section thin-walled steel truss 4 is welded or bolted after being inserted, and additional steel bars can also be added at the joint to realize the lap joint connection of the structural force;

[0078] The vertically distributed steel bars of the shear wall body are all replaced by thin-walled steel trusses 4, and the horizontally distributed steel ...
