Description

An adaptive seismic isolation joint cover that can release temperature deformation

Technical field

The present invention relates to the field of building seismic isolation structures, and more specifically to an adaptive seismic isolation joint cover plate that can release temperature deformation.

Background technique

With the widespread promotion and application of building seismic isolation technology, the number of seismic isolation structures has increased significantly. A key point in the design of seismic isolation structures is the design of seismic isolation joint cover plates. Unreasonable design of seismic isolation joint cover plates will cause serious problems. Affects the performance of isolation joints.

In the seismic isolation design of existing buildings, one end of the seismic isolation joint cover is usually fixed and the other end slides. This structural form mainly has the following problems: First, the main overlap length of the seismic isolation joint cover is set at the seismic isolation joint. On one side, the overlapping length of the overlapping side of the isolation joint cover plate is relatively high. Especially in areas with high earthquake intensity, the width of the structural isolation joints will reach more than 800mm. In some cases, there is not enough space to set up isolation joints. Seismic joint cover; secondly, when the structures on both sides of the seismic isolation joint deform under the action of temperature, the seismic isolation joint cover and the main structure will undergo relative deformation, causing damage to the joint position, thereby affecting the appearance and use; third, The structure of the fixed side of the seismic isolation joint cover is relatively complex, and the construction accuracy is not easy to meet the requirements, and good flatness cannot be achieved. The seismic isolation joint cover is prone to shaking, especially when used for deformation joints on the garage floor. Under the action of vehicle load, the isolation joint cover plate is prone to shaking and noise, and may even cause structural damage.

In the patent "An autonomous resettable seismic isolation joint cover device" (Application No. 2022109231415), the symmetrical overlap length of the cover plates on both sides and the automatic reset of the cover plate can be achieved by setting up an autonomous reset component. The device has an automatic reset function, but the elastic glue at both ends of the cover plate of the device is easily damaged under temperature deformation, and the cover plate will be lifted up by the main structure. Since temperature deformation is a long-term deformation in the isolation structure, this deformation will exist for a long time. It will seriously affect the appearance and use of the seismic isolation joint cover.

Therefore, how to provide an adaptive seismic isolation joint cover plate that can release temperature deformation so that it can overcome the above problems is an urgent problem that those skilled in the art need to solve.
