Multi-cavity type L-shaped anti-seismic corrosion resistant shear wall

Abstract

The invention provides a multi-cavity L-shaped anti-seismic and anti-corrosion shear wall, which belongs to the technical field of construction. The wall of the multi-cavity L-shaped anti-corrosion anti-seismic shear wall is L-shaped, and the wall is composed of aerated concrete, foamed aluminum energy-dissipating materials, fire insulation layer, and anti-corrosion protection layer from the inner layer to the outer layer; the aerated concrete is located in multiple The innermost part of the cavity-type L-shaped anti-corrosion anti-seismic shear wall is equipped with cold-rolled energy-dissipating steel plates at both ends inside the aerated concrete, and reinforcing ribs are installed on the opposite side of the cold-rolled energy-dissipating steel plates at both ends, and cold-rolled energy-dissipating steel plates at both ends The supporting keel column is arranged at the right angle of the wall body through the connection of tie bars, and the cross supporting rib is arranged in the cavity where the supporting keel column is located. The advantages and beneficial effects of the present invention are that it can make the wall have good force bearing capacity, excellent energy consumption and shock absorption capacity, can realize the absorption of vibration energy, and can effectively reduce the weight of the wall body, absorb less seismic force during an earthquake, and can reduce Earthquake response of building structures.

Description

technical field [0001] The invention belongs to the technical field of construction, in particular to a multi-cavity L-shaped anti-seismic and anti-corrosion shear wall. Background technique [0002] Shear walls, also known as wind-resistant walls, seismic walls or structural walls, are used to withstand horizontal loads caused by wind loads or earthquakes in houses or structures. Shear walls can effectively prevent building structures from shear damage. At present, although the prefabrication rate of the fully prefabricated shear wall structure is relatively high, there are many configurations of longitudinal reinforcement and stirrups in the restrained edge members of the shear wall. There are many factors for the deterioration of concrete material properties, especially under the erosion of coastal warm and humid air, the aging phenomenon of concrete structures is very serious. The problem of structural durability damage of buildings has become increasingly prominent, th...

Problems solved by technology

In order to avoid the above-mentioned disasters, people must control the seismic response of the structural system and eliminate the "amplifier" effect of the structural system to protect the main structure and components from damage in strong earthquakes or strong winds. Thickness can be used to improve the above situation, but this will not only increase the amount of concrete, increase the construction strength and cost, but the key point is that the seismic force is proportional to the self-weight of the wall. After the weight increases with the thickness, the earthquake produces The horizontal shear force has also increased, so the effect of the wall's resistance to horizontal shear force, that is, the horizontal bearing capacity is still not ideal. The edge members of the traditional shear wall have the problem of too large reinforcement. The ductility of the shear wall under the earthquake load Insufficient, poor energy consumption capacity, its design and construction are more complicated
