Embodiment Construction

[0015] The technical scheme of the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the description of this article, take a cube as an example, the length direction is the left and right direction, and the width The direction is the front and back direction, and the height direction is the up and down direction.

[0016] Such as figure 1 As shown, the self-resetting CLB rocking wall of the present invention includes a basic steel beam 1 and a cross-layered bamboo wall panel 2 (CLB) arranged on the basic steel beam 1. The staggered laminated bamboo wallboard 2 is provided with a number of unbonded prestressed tendons 12, preferably prestressed steel strands, prestressed rebars or prestressed FRP tendons. One end of the unbonded prestressed tendons 12 is connected to the staggered layer. The top of the jigsaw wallboard 2 is fixedly c...

Abstract

The invention discloses a self-reset cross-laminated bamboo wallboard (CLB) swing wall and a preparation method thereof. The self-reset CLB swing wall comprises a foundation steel beam, a CLB arrangedon the foundation steel beam and friction energy-dissipation devices arranged at the corners of the bottom end of the CLB; each friction energy-dissipation device comprises a first friction energy dissipater and a second friction energy dissipater which are symmetrically arranged and connected. During preparation, the CLB is arranged on the foundation steel beam, the corners of the bottom end ofthe CLB are removed, and the friction energy-dissipation devices are mounted. According to the swing wall, firstly, the CLB is arranged on the foundation steel beam, unbonded pre-stressed tendons andthe friction energy-dissipation devices are arranged, thus in the swing process, the bottom is not prone to being collided and damaged, injury and deformation of the structure can be controlled, the continuous and stable positive pressure can be provided in the swing process, friction force is not lowered in the swing process, and the energy dissipation ability is improved; and in addition, the preparation method of the swing wall is easy and convenient, and operability is high.

Description

Technical field [0001] The invention belongs to the field of rocking walls, and particularly relates to a self-resetting CLB rocking wall and a preparation method thereof. Background technique [0002] In recent years, earthquake disasters have occurred frequently, and the recoverability of cities and buildings after earthquakes has attracted widespread attention. For how to effectively control the damage of the structure and enhance the recoverable performance of the structure, the researchers proposed the study of the seismic performance of the frame-reinforced concrete rocking wall or the research on the energy dissipation elements in the rocking wall. However, the weight of the reinforced concrete rocking wall is heavy, it is difficult to hoist after prefabrication, and the bottom of the rocking wall is prone to collision damage during the rocking process, which adds unfavorable factors to the construction and use of the structure. Summary of the invention [0003] Objective ...
