Problems solved by technology

The anti-blast and impact resistance of the double steel plate concrete shear wall itself is relatively general, while the walls with better blast resistance such as rubber concrete walls do not have high bearing capacity.

Embodiment 1

[0035] Such as Figure 1-3 As shown, a double-steel composite shear wall with a pressure-resistant and untensioned concrete embedded damping interlayer in the present invention includes a concrete core layer 1, a steel plate layer 2, a damping interlayer 3, and an outer concrete layer from the inside to the outside. Layer 4, the two sides of the steel plate layer are respectively connected with steel tube concrete beams 5, and a concrete core is poured between the steel plate layer and the steel tube concrete beams, and the outsourcing is a double steel plate combined shear wall with a pressure-resistant concrete embedded with a damping interlayer It also includes a top plate 6 and a bottom plate 7 welded to the top and bottom of the wall respectively.

[0036] The steel plate layer includes two parallel steel plates. The damping interlayer includes two parallel damping interlayers, and the damping interlayer is located between the steel plate layer and the outer concrete lay...

Embodiment 2

[0046] Such as Figure 4 As shown, the thickness of the CFST bundles on both sides is equal to the thickness of the wall, that is, the thickness of the outsourcing concrete + the thickness of the damping interlayer is equal to the thickness of a single CFST bundle unit. This design has a regular shape for easy assembly.

[0047] All the other technical features are the same as in Embodiment 1.

[0048] Assembly method of the present invention comprises the following steps:

[0049] a. Weld and connect the steel plate layer with the section steel of the steel tube concrete bundle, install and fix the wall restraint tie rod assembly, that is, pass the restraint tie rod through the wall, tighten the nut, pour concrete in the cavity of the steel plate and the section steel, and complete the double steel plate concrete shear Fabrication of force walls and concrete-filled steel tube bundles;

[0050] b. Apply adhesive on the outside of the steel plate layer to firmly bond the ste...

Abstract

The present invention relates to the technical field of construction, and relates to a double steel plate composite shear wall that has an external pressure-bearing and untensioned concrete embedded damping interlayer. The present invention successively comprises from the inside to the outside: a concrete core layer, a steel plate layer, a damping interlayer, and an outer concrete layer. Two sides of the steel plate layer are each connected to a concrete-filled steel tube bundle, and a concrete core is poured between the steel plate layer and the concrete-filled steel tube bundles. The double steel plate composite shear wall that has the external pressure-bearing and untensioned concrete embedded damping interlayer further comprises a top plate and a bottom plate which are connected to top and bottom parts of a wall respectively. In the present invention, the outer concrete layer is not directly connected to the concrete-filled steel tube bundles at the two sides, and there are small cross-sectional areas at the top and bottom parts, so that the outer concrete layer does not directly bear horizontal loads, and will not generate deformations or else generates relatively small horizontal tensile and compressive deformations; and thus, the outer concrete layer only bears vertical loads, which greatly improves the vertical bearing capacity and seismic performance of the wall.

Description

technical field [0001] The invention relates to a double-steel plate combined shear wall with a damping interlayer embedded in pressure-bearing and untensioned concrete, which belongs to the technical field of construction. Background technique [0002] The double-steel composite shear wall has the advantages of light weight, less cracking of corner concrete, better ductility, and fast construction speed. However, the continuous improvement of the height of high-rise buildings puts forward higher requirements on the axial compressive bearing capacity of the wall. At present, double steel plate concrete shear walls are often used as the main load-bearing components in high-rise buildings. The stress state is complex, and it bears vertical and horizontal loads at the same time. Anti-seismic performance. On the other hand, due to the poor fire resistance and corrosion resistance of the steel plate, the double steel plate combined shear wall needs a lot of fireproof and anti-c...
