Concrete shear wall

Abstract

The invention discloses a concrete shear wall characterized by being internally provided with at lease one module, self-compacting concrete is cast outside the module, and the thickness of the self-compacting concrete at two sides of the module is not more than 45 mm, therefore, a structure with complicated shape, thin wall and dense reinforcement is cast and formed, abrasion to a template, caused by vibration, can be avoided, and abrasion to a mixer by concrete can be reduced. Concrete can be used to the largest degree by arranging the module internally, thereby saving cost; moreover, excellent heat preservation, sound insulation and heat insulation effect can also be achieved by arranging the module in the wall; in addition, shock resistance of the wall can be enhanced greatly by forming non-continuous joint seams in the wall; by casting a thin layer of steel screens at two sides of the module, compact casting and high strength can also be achieved, a large amount of concrete can be saved, and especially compression strength, density, tensile strength, breaking strength, modulus of elasticity and other indexes are effectively improved. The concrete shear wall is applicable to wall structures of various high-rise buildings, medium-height buildings and even skyscrapers.

Description

(1) Technical field [0001] The invention relates to a concrete shear wall. (2) Background technology [0002] With the rapid development of the economy and the improvement of living standards, the awareness of environmental protection and energy conservation has gradually increased, and traditional clay materials will be replaced by new materials. The wall uses concrete hollow blocks to replace clay bricks as the main material in modern times. This kind of masonry structure has good thermal insulation performance, sound insulation performance, fire resistance and durability, but its low strength and large size reduce the useable area of ​​the building. , and prone to problems such as leakage and cracking. And no matter the connection between clay bricks or hollow blocks is mainly the mortar bonding between them, the wall body of this structure has poor seismic performance. Some new types of walls continue to appear. The future development trend of our country is to adopt t...

Problems solved by technology

Commercial concrete is widely used in pumping construction. For pumping, the amount of cement is increased, the content of medium and coarse aggregates and aggregate particle size are reduced, and the mixing ratio of pumped concrete and the influence of adverse factors during construction and feeding are all increased. Structural shrinkage, increasing factors for cracks

Moreover, the shear wall structure used in the market has obvious disadvantages. First, the distance between the shear walls should not be too large, and the plane layout is not flexible, which cannot meet the requirements of public buildings. Second, the self-weight of the structure is often large, resulting in an increase in the amount of building materials , the seismic force increases, making the superstructure and foundation design difficult
