Processing method of prefabricating common concrete outer plate recycled concrete core shear wall

Abstract

The invention relates to a regenerated concrete core shear wall provided with precast common concrete outside plates and a processing method thereof. The structure of the shear wall is divided into three layers along the thickness direction, wherein an intermediate layer is a cast-in-situ regenerated concrete layer (2), and an upper surface layer (1) and a lower surface layer (1) are the precast common concrete outside plates; a horizontal reinforcement (3) and a vertical reinforcement (4) are arranged inside the precast common concrete outside plate layers on both sides; one end of a bondingreinforcement (5) is bound on a reinforcement mat, and the other end of the bonding reinforcement (5) is extended into the regenerated concrete layer; the length of the bonding reinforcement (5) is the thickness of the regenerated concrete layer; the horizontal reinforcement and the vertical reinforcement are extended out of the precast common concrete outside plates (1), and the length of the horizontal reinforcement and the vertical reinforcement is more than the reinforcement anchoring length; and the precast common concrete outside plates (1) are taken as templates of reinforced concrete members, cast in situ with regenerated concrete (2) in the middle, and combined into a whole. The shear wall and the processing method thereof solve the problem of damage of the ecological environmentdue to increasing shortage of natural aggregate and mining of a large quantity of sandstones.

Description

technical field [0001] The invention belongs to a shear wall, in particular to a processing method of a prefabricated ordinary concrete outer plate recycled concrete core shear wall. Background technique [0002] With the acceleration of urbanization, concrete, which is the main building material, is now consuming natural aggregate at a rate of about 8 billion tons per year. At the same time, more and more civil engineering construction projects are scrapped and demolished, resulting in a large amount of waste concrete. On the one hand, it is the exploitation of a large amount of natural resources, and on the other hand, it is the generation of a large amount of construction waste. Contradictions between the sustainable development of concrete and aggregate supply and demand have become increasingly prominent. [0003] Recycled concrete is showing strong vitality with its characteristics of energy saving, soil saving, waste utilization and environmental improvement. Resear...
