Abstract

The invention discloses an assembly type concrete shear wall connection method based on a mortise and tenon structure, and belongs to the technical field of building engineering. The method involves two shear walls (the wall joint is made into a mortise and tenon shape and a reserved hole corresponding to the concave-convex part of the mortise and tenon), a plurality of prestressed reinforcements,a plurality of sleeves and a certain area of carbon fiber. The method mainly utilizes the mortise and tenon structure, a sleeve grouting technology, the prestressed reinforcement and a carbon fiber material to optimize the connection between the walls. The method solves the problems of poor shock resistance, low strength, poor crack resistance, poor resistance to temperature deformation and the like at the joint of the existing fabricated shear wall, and is suitable for assembling the connection of the shear walls.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to optimizing the connection between prefabricated shear walls by using a mortise and tenon structure. Background technique [0002] The prefabricated shear wall structure is a modern building structure mode. Different from the traditional concrete building method, this kind of building adopts the assembled method, which consumes relatively little water and energy, and does not generate solid waste, garbage, pollution such as sewage. At the same time, this construction method is also conducive to the realization of housing industrialization, which is conducive to building energy saving and emission reduction. The prefabricated structure is mainly used to complete the main structure of the building through the manufacturer's reservation and on-site assembly. It has good adaptability in some areas with poor construction conditions. In recent years, with the introduc...
