Description

TECHNICAL FIELD

[0001] The present application relates to the field of building isolation structure, more particularly to a self-adaptive isolation joint cover plate capable of releasing temperature deformation. BACKGROUND

[0002] With the popularization and application of building isolation technology, the number of isolation structures has increased significantly. A key point in the design of isolation structures is the design of isolation joint cover plates. Unreasonable design of isolation joint cover plates can seriously affect the performance of isolation joints.

[0003] In the existing isolation design of buildings, the isolation joint cover plate is generally fixed at one end and slides at the other end. This construction form mainly has the following problems: first, the main lap length of the isolation joint cover plate is set on one side of the isolation joint, which requires a higher lap length on the lap side of the isolation joint cover plate, especially in high-intensity earthquake areas, the width of the structural isolation joint can reach more than 800mm, and in some cases there is not enough space to set the isolation joint cover plate; second, under the action of temperature, when the structures on both sides of the isolation joint deform, the isolation joint cover plate and the main structure will deform relatively, causing damage to the joint position, thereby affecting the appearance and use; third, the fixed side structure of the isolation joint cover plate is complex, and the construction precision cannot meet the requirements, so it is difficult to achieve good flatness, and the isolation joint cover plate is prone to shaking, especially when used as a deformation joint for a garage layer, under the action of vehicle load, the isolation joint cover plate is prone to shaking and noise, and even structural damage.

[0004] In the patent "Isolation joint cover plate device capable of automatic resetting" (application number 2022109231415), the symmetrical lap length of the two sides of the cover plate and the automatic resetting of the cover plate can be achieved by setting the automatic resetting assembly. Although the automatic resetting function of the cover plate is achieved, the elastic glue at both ends of the cover plate is easily damaged under temperature deformation, and the cover plate is lifted by the main structure. Since temperature deformation is a long-term deformation in isolation structures, the long-term existence of this deformation will seriously affect the appearance and use of the isolation joint cover plate position.

[0005] Therefore, how to provide a self-adaptive isolation joint cover plate capable of releasing temperature deformation to overcome the above problems is a problem that needs to be solved by those skilled in the art. SUMMARY

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the application will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the application, but not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0030] The application discloses a self-adaptive isolation joint cover plate capable of releasing temperature deformation. The cover plate body 4 in the application can be reliably overlapped with the main body structure one 1 and the main body structure two 2, and the cover plate body 4 has the same overlapping length on both sides of the isolation joint 3. When the main body structure one 1 and the main body structure two 2 move towards each other in a large range, the main body structure one 1 moves close to the main body structure two 2 in a large range, or the main body structure two 2 moves close to the main body structure one 1 in a large range, the cover plate body 4 can be lifted to release the deformation of the isolation joint 3 through the design of the arc-shaped piece. In the case that the main body structure one 1 and the main body structure two 2 do not move relatively, move away from each other, or move towards each other in a small range, the side plate surface of the cover plate body 4 provided with the arc-shaped piece can always simultaneously abut against the main body structure one 1 and the main body structure two 2, so that the deformation release of the isolation joint 3 under the temperature and the small earthquake is realized. That is, when the main body structure one 1 and the main body structure two 2 move within a certain deformation range, the cover plate body 4 will not be lifted. When the main body structure one 1 and the main body structure two 2 move, the tension spring one 8 and the tension spring two 9 in the elastic piece can ensure that the cover plate body 4 and the arc-shaped piece are always opposite to the isolation joint 3, so as to prevent the cover plate body 4 from falling to the inner side of the isolation joint 3. After the deformation of the main body structure one 1 and the main body structure two 2 ends, the cover plate body 4 can automatically reset. EMBODIMENT
