Abstract

The invention belongs to the field of civil engineering, and relates to a fabricated shear-wall energy-dissipation vibration-reduction horizontal connecting device and a construction method thereof. A pre-embedded part and a connecting part of the fabricated shear-wall energy-dissipation vibration-reduction horizontal connecting device are both arranged in the wall body, changes of performances such as corrosion, erosion and aging can be avoided, the durability of the whole structure is ensured, plane outer warping of an energy-dissipation connecting device is avoided, and the better energy-dissipating capacity can be achieved. The energy-dissipation connecting part is placed in the wall body and coincides with the axis of a horizontal shaft of the section of the wall body, force balance of the wall body, rigidity in the plane and carrying capacity are ensured, and eccentric bending moment can not be generated. With the connecting mode, the efficiency of prefabricated shear-wall on-site assembling construction can be improved substantially, enough initial rigidity supplied to shear-wall to connect under the function of small vibration can be achieved, under the function of big vibration, earthquake energy can be dissipated, and vibration-reduction thoughts of structure and component ductility can be improved, and meanwhile, the whole effect of building beauty and space usage can not be influenced, steel products can be saved, and a certain economic benefit can be achieved.

AI Technical Summary

Problems solved by technology

In the traditional prefabricated shear wall structure, the main method of horizontal connection is to reserve horizontally distributed steel bars through the prefabricated shear wall. After installation and positioning on site, it is connected with the longitudinally stressed steel bars, and then the formwork is erected and concrete is poured to form , this horizontal connection technology has the following problems: it is difficult to connect steel bars, and concrete needs to be poured with vertical formwork.

[0004] When this connection method is applied to solve the prefabricated shear wall, the interface shear connectors are welded on the surface of the wall, and the front and rear cannot be one-to-one. If the force is unbalanced, eccentric bending moments will be generated, which will affect the in-plane performance of components; due to the exposure of embedded parts and connectors, performance changes such as rust, corrosion, and aging will occur, which will affect the durability of the structure, etc.
