Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a self-resetting concrete shear wall with a built-in spring. The concrete shear wall solves the problem of severe damage to the foot of the walls on both sides of the existing concrete shear wall after being loaded, poor ductility, and problems with swinging walls and cracks. The stability of the shear wall is poor, the elastic deformation of the prestressed tendons is small, and the shape memory alloy is affected by temperature.

Embodiment Construction

[0028] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0029] Such as Figure 1-3 The shown built-in spring self-resetting concrete shear wall includes: a reinforced concrete shear wall 10 and a spring device 20, the reinforced concrete shear wall 10 includes a wall 11 and a support 12, and the wall 11 is located on the support 12, all composed of Made of steel and concrete. There are two spring devices 20 , which are symmetrically arranged at the foot of the junction of the wall 11 and the support 12 . The reinforced concrete shear wall 10 is the same as the ordinary reinfo...

Abstract

The invention discloses a built-in spring self-resetting concrete shear wall. The built-in spring self-resetting concrete shear wall comprises a reinforced concrete shear wall body and two spring devices. The reinforced concrete shear wall body comprises a supporting seat integrally formed and a wall body located on the supporting seat. The two spring devices are symmetrically arranged on the wall foot where the wall body and the supporting seat are connected. According to the built-in spring self-resetting concrete shear wall, the spring devices on the two sides of the wall foot can ensure that the wall foot cannot be partially damaged prematurely, and thus the whole component cannot fail. Springs provide resilience after being compressed so that the function of the wall body can be restored.

Description

technical field [0001] The invention relates to the field of shear walls. More specifically, it relates to a self-resetting concrete shear wall with a built-in spring. Background technique [0002] Earthquake is a serious natural disaster faced by human beings for a long time, which will cause a large number of casualties and damage or collapse of buildings. Due to the uncertainty and complexity of earthquakes, the seismic action suffered by buildings is often impossible to predict accurately, and the damage or even destruction of buildings will have a great impact on people's normal life, and it will also cost a lot of money to repair buildings. Manpower, material resources and time cause huge losses to the social economy. Therefore, how to reduce structural damage when an earthquake occurs, enable people to return to normal life as soon as possible after the earthquake, and make buildings and even the entire city resilient have become new issues of concern in the field o...
