Recycled concrete shear wall with cross reinforcement conversion layer and its production method

Abstract

The invention relates to a regenerated concrete shear wall provided with a cross reinforcement conversion layer, which belongs to shear wall structure, wherein the lower part of the shear wall adopts common concrete, and the upper part of the shear wall adopts regenerated concrete; the thickness of the intermediate conversion layer is 3 times that of the shear wall, and an X-shaped reinforced sway brace is arranged inside the intermediate conversion layer; and the reinforced sway brace is connected with a reinforcement mat of the shear wall, and a hidden brace is formed inside the concrete shear wall. The regenerated concrete shear wall provided with the cross reinforcement conversion layer gives full play to the advantages of two types of concrete, and utilizes a regenerated concrete structure to optimize the structural design and guarantee the structural performance. The lower part of the shear wall with larger shearing force adopts the common concrete with stable performance, and the upper part of the shear wall with smaller shearing force adopts the regenerated concrete with slightly poor performance. A cross reinforcement is arranged on the conversion layer of which the stiffness is suddenly changed, so that shearing resistant slippage between different concrete layers can be prevented, and simultaneously variation of the shearing resistant bearing capacity of the shear wall has a transitional process.

Description

Technical field [0001] The invention relates to a recycled concrete shear wall with a cross-reinforced conversion layer and a manufacturing method thereof, belonging to a shear wall structure system. Background technique [0002] At present, the amount of construction waste in my country has accounted for 30% to 40% of the total urban waste, and the most important component is waste concrete; at the same time, a large amount of natural sand and gravel aggregates are continuously mined, and natural aggregate resources Will also tend to dry up. Recycled concrete technology is a technology in which waste concrete blocks are crushed, washed, and graded, and mixed in a certain proportion to make recycled concrete aggregates, and then the aggregates are partially or completely replaced by natural aggregates to prepare concrete. The application of this technology meets the requirements of sustainable development of human society. [0003] In the building structure, the shear wall is the ...
