Embodiment Construction

[0025] Below in conjunction with accompanying drawing and specific implementation process, the present invention will be further described:

[0026] A laminated slab shear wall with recoverable function, which combines semi-assembled laminated technology and post-tension prestressed prefabrication technology to form a laminated slab shear wall with recoverable function. The post-tensioned unbonded prestressed tendons 4 are set in the core cast-in-place part 12 of the laminated slab shear wall, and there is no need to reserve holes in the prefabricated wall panels, which has the advantage of convenient construction. Since the prestressed tendons are unbonded, the It can still maintain elasticity when it is greatly deformed, so the structural recovery ability is good, and the residual deformation after the earthquake is small. In the semi-assembled laminated plate reinforced concrete shear wall, the two ends of the horizontal joints 9 that may undergo plastic deformation under r...

Abstract

The invention discloses an overlapped plate type shear wall with the restorability and a constructing method of the shear wall. The shear wall comprises an overlapped wallboard, unbonded prestressed reinforcing steel and a half-assembly overlapped plate type reinforced concrete shear wall body which is composed of outer steel plates at the positions of horizontal splicing seams. The prefabricated part of the overlapped plate type shear wall is composed of two layers of prefabricated plates and lattice steel bars having the connecting effect, after prefabricated components are installed in place on site, necessary connecting steel bars and necessary stressed steel bars are arranged, and concreting is performed at the core position of a prefabricated wallboard to form an overlapped stressed structure. According to the overlapped plate type shear wall, the post-tensioning unbonded prestressed reinforcing steel is arranged at the core cats-in-place position of the overlapped plate type shear wall, elasticity of the unbonded prestressed reinforcing steel can be kept under the condition of a rare-occurrence earthquake, and therefore residual deformation of the shear wall is small after the earthquake, the shear wall has the self reset function, and the shear wall is convenient to repair after the earthquake; the outer steel plates easy to replace after the earthquake are adopted at the positions of the horizontal splicing seams of the overlapped plate type shear wall, the steel plates bend under the condition of the rare-occurrence earthquake, energy of the earthquake is dispersed, the shear wall is convenient to replace after the earthquake, and the restorability of the shear wall is improved further.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a function-restorable laminated plate shear wall and an implementation method thereof. Background technique [0002] The structure involved in this patent is a semi-assembled laminated slab type reinforced concrete shear wall structure with laminated wall panels and laminated floor slabs as the main stress components. Among them, the prefabricated concrete wall panels are composed of two layers of prefabricated slabs connected by lattice steel bars, and lattice steel bars are also arranged in the prefabricated floor slabs. The lattice reinforcement is composed of three upper and lower chord reinforcements with an isosceles triangle cross-section and oblique web reinforcement formed by bending. Has sufficient strength and rigidity. After the prefabricated components are installed on site, set up the necessary connecting steel bars and stress steel bars...
