Description

Technical Field

[0001] The utility model relates to the technical field of structural vibration control, in particular to a vertically highly adaptive multi-layer structural seismic isolation and tensile resistance device. Background Art

[0002] In seismic design, seismic isolation layers are a key tool, reducing the risk of damage by minimizing the transfer of seismic energy to upper structures. However, during earthquakes, seismic isolation layers experience not only horizontal deformation but also vertical tensile forces. Traditional seismic isolation layer tensile devices often face a conflict between vertical stiffness and horizontal deformation capacity, making it difficult to achieve a balance between the two.

[0003] Currently, commonly used tensile devices often employ planar guides or rigid connection structures. While these devices can provide a certain degree of vertical tensile resistance, their rigid design can easily lead to stress concentration and component failure when subjected to large horizontal deformations. Furthermore, the height of the isolation layer can change significantly with the dynamic effects of earthquakes. Due to the limitations of their planar design, traditional guide rail mechanisms often cannot adapt to these height variations, thus compromising the isolation effectiveness. Especially during strong earthquakes, these devices may fail, failing to provide adequate tensile protection.

[0004] Under the action of an earthquake, the traditional tensile device will increase the friction between the guide rail and the connecting parts due to the vertical force, generating strong static friction, which will prevent the device from sliding normally. Summary of the Invention

[0005] In order to solve the problems of the above-mentioned prior art, the utility model provides a seismic isolation layer tensile device with adaptive vertical stiffness adjustment to solve the deficiencies in the prior art. Through the innovative multi-layer curved guide rail structure design, the deficiencies in the prior art are solved and the comprehensive performance of the seismic isolation layer under seismic conditions is improved. The main features of the seismic isolation layer tensile device are: vertical tensile resistance; horizontal coordinated deformation; the height of the seismic isolation layer will change under the action of an earthquake. Since the guide rail is curved, the height of the device can be adaptively adjusted along with the seismic isolation layer; due to the multi-layer curved guide rail structure, the plane size is smaller than that of the traditional guide rail mechanism, which is convenient for the installation of the seismic isolation layer.

[0006] In addition, the utility model can avoid the problem that traditional tensile devices cannot slide due to vertical tension. The guide rail connector of the utility model is equipped with a roller in the middle, which reduces the friction between the connector and the slide rail when unloading, and solves the problem that traditional tensile devices are difficult to reset.

[0007] Furthermore, the present invention adds damping materials such as rubber and lead core between the curved slide rail connectors, and can also provide energy dissipation together with the seismic isolation support, thereby improving the seismic isolation effect of the seismic isolation layer and improving the safety of the structure.

[0008] The purpose of this utility model is achieved through the following technical solutions:

[0009] A vertically adaptive multi-layer seismic isolation and tensile device includes flange plates at both ends, the upper flange plate being welded to the top of the upper slide rail; the lower flange plate being welded to the bottom of the lower slide rail; a middle slide rail being provided between the upper and lower slide rails; the upper and middle slide rails being perpendicular to each other; and the middle and lower slide rails being perpendicular to each other, that is, the upper and lower slide rails are parallel; the upper and middle slide rails, as well as the middle and lower slide rails, are connected by slide rail connectors; curved grooves are provided in the middle of the upper, middle, and lower slide rails; the upper opening of the slide rail connector snaps into the curved groove of the upper slide rail, and the lower opening of the slide rail connector snaps into the curved groove of the lower slide rail. This connection method allows the displacement to be orthogonally decomposed into displacements in three directions.

[0010] A further improvement of the present invention is that the middle slide rail includes two middle slide rails, the two middle slide rails are vertically arranged in pairs, the upper middle slide rail and the upper slide rail are vertically arranged, and the lower middle slide rail and the lower slide rail are vertically arranged.

[0011] A further improvement of the present invention is that the slide rail connector includes a roller system and two clips, the roller system is parallel to the end face of the clip and is embedded in the side opening of the clip; the two clips are inwardly buckled with each other and placed perpendicular to each other; the roller system is used to limit the vertical displacement of the clips to ensure that the clips do not detach from each other; the roller system can also ensure that the friction contact surface is reduced when the device is unloaded to ensure its self-resetting ability.

[0012] A further improvement of the utility model is that the roller system includes a bearing and a roller, the bearings are embedded in both ends of the roller, and the bearings are embedded in the openings on the side surfaces of the buckle.

[0013] A further improvement of the present invention is that the curvature of the inner wall of the buckle end face is consistent with the curvature of the curved groove, and the end face is ground and polished so as not to affect its sliding during the loading process.

[0014] A further improvement of this utility model is that damping material is provided between two adjacent rail connectors. The damping material comprises a rubber layer and a lead core. The rubber layer is vulcanized to the clip ends of the rail connectors. The lead cores are embedded in the clip ends of the rail connectors and are spaced equidistantly. When the device deforms, the displacement of the clips dissipates energy in the damping material, thereby enhancing the seismic isolation effect of the isolation layer.

[0015] A further improvement of the present invention is that the rubber layer is made of high damping rubber or laminated rubber. Different materials have different energy dissipation capabilities, and appropriate damping materials can be selected according to actual conditions to maximize the energy dissipation capability of the device.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. Under the action of an earthquake, the traditional anti-tension device will increase the friction between the guide rail and the connector due to the action of vertical force, generating strong static friction, which makes it impossible for the device to slide normally; the utility model is designed as a curved guide rail, which completely avoids the problem of the device being unable to slide due to vertical tension. The guide rail connector of the utility model is equipped with a roller in the middle, which reduces the friction between the connector and the slide rail when unloading, and solves the problem that the traditional anti-tension device is difficult to reset.

[0018] 2. The traditional tensile device has no damping material inside, which occupies the space of the isolation layer and cannot assist the supports of the isolation layer in providing energy dissipation. The utility model adds damping materials such as rubber and lead core between the curved slide rail connectors, which can provide energy dissipation together with the isolation supports, thereby improving the isolation effect of the isolation layer and improving the safety of the structure.

[0019] 3. The compact structure and small dimensions of this utility model facilitate installation in confined spaces, making it particularly suitable for integrated applications within building seismic isolation layers. Through the optimized design of the guide rail connectors, this device not only maintains excellent rigidity during earthquakes but also achieves coordinated deformation in the horizontal direction, effectively dispersing external forces and improving the overall stability and safety of the building structure. This utility model has a simple structure and is easy to use, making it suitable for the seismic resistance requirements of a variety of building structures. BRIEF DESCRIPTION OF THE DRAWINGS
