AI Technical Summary

Problems solved by technology

[0002] Concrete walls filled with steel frames are a common structure, but the concrete material is easy to crack and has poor ductility, which seriously does not match the deformation capacity of the steel frame. Under earthquake action, the concrete wall is prone to wide cracks, and the concrete wall is crushed in the compression zone. Concrete walls are damaged greatly and will quit work earlier, and cannot restore function after the earthquake
For the steel frame filled concrete wall, the concrete wall is completely filled in the steel frame by welding studs, the concrete wall can only be poured on site after the steel frame is installed, the construction period is long, and the concrete wall cannot be replaced and repaired after the earthquake

example

[0033] Based on the technical scheme of the present invention, such as figure 1 , 2 , 3 and 4, the specific construction method is as follows:

[0034] The height of the steel frame is 3300mm, the span is 3900mm, and the steel material is Q345B grade. The connection design of steel frame beams and columns is designed according to the principle of "strong joints and weak components".

[0035] The lateral force-resistant wall made of strong and tough composite materials is 2560mm high, 1200mm wide, and 130mm thick, and steel mesh is laid inside the wall. The top of the strong and tough composite material anti-lateral force wall is equipped with embedded T-shaped steel plates, and the bottom is equipped with base beams. The web plate of the T-shaped steel plate and the connecting plate shall reserve oblong holes, and the flange plate of the T-shaped plate and the flange plate of the base beam shall reserve bolt holes. The top and bottom of the lateral force-resistant wall mad...

Abstract

The invention provides a steel frame function-recoverable high-toughness composite material lateral force resisting wall. The steel frame function-recoverable high-toughness composite material lateral force resisting wall comprises steel frame columns, steel frame beams and a high-toughness composite material lateral force resisting wall body; a grid-shaped rectangular frame is defined by the steel frame columns and the steel frame beams; and the high-toughness composite material lateral force resisting wall body is arranged in the grids. The steel frame beams are connected with the pre-manufactured high-toughness composite material lateral force resisting wall body through oblong hole bolts, synchronous installation of the steel frame and the lateral force resisting wall body is achieved, the construction period is shortened, the replacement and maintenance requirements of the lateral force resisting wall after an earthquake can be met, and function recovery is achieved.

Description

technical field [0001] The invention belongs to the technical field of building anti-seismic technology, and in particular relates to a steel frame recoverable function strong toughness composite material anti-lateral force wall. Background technique [0002] Concrete walls filled with steel frames are a common structure, but the concrete material is easy to crack and has poor ductility, which seriously does not match the deformation capacity of the steel frame. Under earthquake action, the concrete wall is prone to wide cracks, and the concrete wall is crushed in the compression zone. Concrete walls are highly damaged and will quit working earlier, and cannot recover their functions after an earthquake. For the steel frame filled concrete wall, the concrete wall is completely filled in the steel frame by welding studs. The concrete wall can only be poured on site after the steel frame is installed. The construction period is long, and the concrete wall cannot be replaced or...
