Embodiment Construction

[0018] The structural form of the recycled concrete shear wall with cross-reinforcement transfer layer is as follows: Figure 1-2 As shown, the lower part is made of ordinary concrete 1, and the upper part is made of recycled concrete 2. An X-shaped steel bar diagonal support 4 is arranged inside the two steel meshes 5 of the transfer layer 3 in the middle of the shear wall, and its upper end extends into the upper shear wall with a length greater than It is equal to 2 times the thickness of the wall, and is bound to the steel mesh 5 in the shear wall; its lower end extends into the lower shear wall, and its length is greater than or equal to 2 times the thickness of the wall, and is tied to the steel mesh 5 in the shear wall catch. Other structural reinforcements include: the two pieces of steel mesh 5 in the shear wall are connected by tension bars with a spacing less than or equal to 600mm.

[0019] Its production steps are as follows:

[0020] 1) Configure the reinforcem...

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 transfer 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 amount of urban waste, and the most important component is waste concrete; will also be exhausted. Recycled concrete technology is a technology that crushes, cleans and grades waste concrete blocks, mixes them in a certain proportion to make recycled concrete aggregates, and then partially or completely replaces natural aggregates with the aggregates to make 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 core anti-seismic component of the building structure, which bears 80% of the seismic action of the whole structure. Therefore,...
