Description
Technical Field
The invention relates to a double-steel-plate composite shear wall wrapped with pressure-bearing non-tensioned concrete and embedded with a damping interlayer, and belongs to the technical field of buildings.
Background
The double-steel-plate combined shear wall has the advantages of light self weight, difficult cracking of corner concrete, good ductility, high construction speed and the like. However, the continuous increase of the height of the high-rise building puts higher requirements on the axial pressure bearing capacity of the wall. At present, the double-steel-plate concrete shear wall is often used as a main bearing component in a high-rise building, is complex in stress state, simultaneously bears vertical and horizontal loads, and is under the combined action of bending, shearing and twisting, cracks develop early, and the bearing capacity and the anti-seismic performance of the wall are influenced. On the other hand, the double-steel-plate combined shear wall needs a large amount of fireproof and anticorrosive coatings due to the poor fire resistance and corrosion resistance of the steel plates, so that the maintenance cost is high.
Most of the existing double-steel-plate concrete shear walls are made by casting in situ, and after an earthquake occurs, deformation is easy to occur and energy is consumed. The cast-in-place wall is time-consuming and labor-consuming and has higher cost when being repaired or replaced.
In addition, with the development of special buildings and the threat of terrorism, the anti-explosion and anti-impact capabilities gradually become one of the important properties of the wall. The anti-explosion and anti-impact capabilities of the double-steel-plate concrete shear wall are relatively common, and the walls with better anti-explosion performance, such as rubber concrete walls, do not have high bearing capacity. The steel plate concrete combined shear wall wrapped with the concrete layer and added with the damping layer can improve the out-of-plane anti-explosion and anti-impact performance of the shear wall due to the wrapping protection effect of the concrete layer and the superior performances of strong elasticity, large deformation, good barrier property and the like of the damping material.
Disclosure of Invention
The invention aims to overcome the defects of the existing double-steel-plate concrete shear wall, provides the assembled double-steel-plate concrete combined shear wall with the embedded damping interlayer, which is partially wrapped by compression-resistant unstressed concrete, and has the advantages of compression resistance, no tension of the wrapped concrete, high vertical bearing capacity of the wall body and excellent earthquake resistance; the out-of-plane antiknock and impact resistance performance is good; the fire resistance and the durability are good, and the maintenance cost is low; the vertical connection method has the advantages of high assembly degree, simple operation and reliable connection quality.
The invention is realized by adopting the following technical scheme:
the double-steel-plate combined shear wall with the externally-coated pressure-bearing non-tensioned concrete embedded damping interlayer comprises a concrete core layer, a steel plate layer, the damping interlayer and an externally-coated concrete layer which are sequentially arranged from inside to outside, wherein steel pipe concrete bundles are respectively connected to two sides of the steel plate layer, a concrete core is poured between the steel plate layer and the steel pipe concrete bundles, and the externally-coated pressure-bearing non-tensioned concrete embedded damping interlayer further comprises a top plate and a bottom plate which are respectively connected to the top and the bottom of the wall body.

The outer concrete layer comprises two parallel concrete layers which are respectively wrapped outside the two damping interlayers.
The double-steel-plate combined shear wall with the externally-wrapped pressure-bearing non-tensile concrete embedded damping interlayer is formed by connecting constraint pull rod assemblies.

Due to the design, the outer concrete coating is not directly connected with the steel tube concrete bundles on two sides, and the outer concrete coatings on the top and the bottom have smaller cross-sectional areas, so that the outer concrete coating does not directly bear horizontal load and cannot generate or generate smaller horizontal tension-compression deformation; and then make outsourcing concrete layer only bear vertical load, great promotion the vertical bearing capacity and the anti-seismic performance of wall body.
The concrete-filled steel tube bundle comprises six concrete-filled steel tube bundle units, and the number of the two sides of the wall body is three respectively.
