Prefabricated recycled concrete shear wall with energy dissipation connector and fabrication method

Abstract

The invention discloses a prefabricated recycled concrete shear wall with an energy dissipation connector and a fabrication method and belongs to the field of construction. Recycled concrete with a strength grade which is not lower than C40 is used in the shear wall, a horizontal reinforcing steel bar and a vertical reinforcing steel bar are arranged in the shear wall, a portion of the horizontal reinforcing steel bar, which extends out of the shear wall, is hooked, U-shaped steel grooves are arranged on the side surface of the shear wall from top to bottom at equal intervals, two shear walls are located at the same horizontal height by corresponding to the U-shaped steel grooves, and two fin boards of the U-shaped steel grooves are horizontally buried in the shear walls. When two pieces of shear walls are connected, corresponding U-shaped steel grooves are connected by steel bars and fixed by bolts, longitudinal long through steel bars are inserted into a hook, and low strength concrete is poured between the two pieces of shear walls. The shear wall has the advantages that the structure is simple, the construction costs are low, the construction is convenient, the anti-seismic performance is good, the problems that a large amount of wasted concrete is difficult to dispose and the ecological environment is increasingly deteriorated due to the wasted concrete are expected to be solved, simultaneously the energy-dissipating capacity of a house is enhanced, the wet workload on a construction site is reduced, the construction is accelerated, and the labor costs are lowered.

Description

technical field [0001] The invention belongs to a shear wall, in particular to a prefabricated recycled concrete shear wall with energy-dissipating connection keys and a method thereof. Background technique [0002] In the past 10 years, with the acceleration of urban construction in our country, many old buildings have reached the end of their service life. In addition to regional renovation and other projects, concrete as the main building material is now consuming natural aggregates at a rate of about 8 billion tons per year. The traditional landfill treatment of waste concrete not only needs to occupy a lot of land resources, but also consumes a lot of construction funds. On the one hand, the exploitation of a large amount of natural resources, on the other hand, the generation of a large amount of construction waste, the sustainable development of concrete and the contradiction between supply and demand have become increasingly prominent. [0003] With the strengthenin...

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of prefabricated shear wall with the advantages of simple structure, low cost, convenient construction, and good seismic performance, in order to solve the problem of difficult disposal of a large amount of waste concrete and the deterioration of the ecological environment caused by it, and at the same time strengthen the building Energy consumption capacity, reduce the amount of wet work on the construction site, speed up the construction speed and reduce labor costs
