Description

Technical Field

[0001] The patent of this invention relates to the technical field of building seismic isolation, and in particular to a tensile support with a buffer device. Background Art

[0002] The working principle of rubber seismic isolation bearings is to set rubber seismic isolation bearings between the upper structure and the top surface of the foundation of the building, or between the interlayer structures. Through the effective work of the seismic isolation bearings, the input of seismic waves to the upper structure is limited and reduced, and the seismic effect of the upper structure and the deformation of the seismic isolation bearings are controlled, thereby reducing the seismic response of the entire building and achieving the purpose of earthquake resistance.

[0003] With the development of the global economy and the acceleration of urbanization, high-rise and super-high-rise buildings are appearing frequently. Base isolation is a simple and effective vibration reduction technology that has been widely used in various low- and medium-rise buildings, achieving excellent vibration reduction results. In recent years, this technology has been gradually expanded to high-rise and super-high-rise buildings. Because the overturning moment generated by horizontal seismic forces in high-rise and super-high-rise buildings is large, rubber isolation bearings are prone to tensile stress under strong earthquake motion. Under strong earthquake motion, structures with large aspect ratios will experience significant jolts and sway, which will further exacerbate the tensile stress on rubber isolation bearings. When rubber isolation bearings are subjected to axial tension, although they appear to show no significant damage, negative pressure can easily form within them, creating numerous voids. Research has shown that when rubber isolation bearings are subjected to compression after significant tensile deformation, their vertical compressive stiffness decreases to approximately half of their initial stiffness. Furthermore, when the tensile stress reaches 1.5-3.0 MPa, the tensile stiffness of the bearings drops sharply, exhibiting a bilinear characteristic.

[0004] This invention utilizes tensile bearings and seismic isolation rubber bearings in conjunction with each other within the isolation layer, leveraging their synergistic effects. The seismic isolation rubber bearings within the isolation layer provide greater energy dissipation, while the tensile bearings enhance the vertical tensile resistance of the isolation layer. To prevent significant impacts caused by gaps in the tensile bearings when subjected to tension, disc springs are used at the connection between the tensile bearings to cushion impact loads. Summary of the Invention

[0005] The present invention addresses the shortcomings of existing technologies by providing a tensile support with a simple structure, easy installation, and strong tensile strength. By configuring the guide rails to be bidirectional and providing tensile fasteners between them, the tensile support is installed where the seismic isolation layer is subject to significant tensile forces. Furthermore, disc springs are employed at the connection points of the tensile support to cushion impact loads. This tensile support is used to address the issue of tensile forces or overturning moments on seismic isolation supports in high-intensity areas.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A tensile support with a buffer device includes upper and lower flange plates and matching guide rails. The guide rails of the upper and lower flange plates are arranged in a bidirectional cross and distributed vertically. A tensile fastener with a clearance fit is provided between the guide rails of the upper and lower flange plates, and the slide groove of the tensile fastener can slide easily on the guide rail.

[0008] And when in use, the tensile supports of this application can be connected in parallel to achieve the effect of doubling the output.

[0009] The tensile fasteners and guide rails are combined in two or four pairs.

[0010] Furthermore, the flange plate includes an upper flange plate and a lower flange plate, and the guide rail includes an upper guide rail and a lower guide rail. The upper flange plate and the lower flange plate are rectangular plate structures with two rows of countersunk holes in the middle portion thereof. The upper guide rail and the lower guide rail are T-shaped structures with two rows of threaded holes on the back thereof. The upper guide rail and the lower guide rail are respectively connected to the upper flange plate and the lower flange plate with high-strength bolts through the countersunk holes and the threaded holes, and the bolt heads do not protrude from the flange plates.

[0011] Furthermore, the tensile fastener is composed of a slide groove, a T-shaped undercut, a limiter and a lower connecting slide groove through assembly.

[0012] Furthermore, the tensile fastener is an integral structure and is manufactured by direct processing without assembly.

[0013] Furthermore, the tensile fastener is composed of a slide groove, a tensile steel rope, and an anchor through assembly.

[0014] Furthermore, the flange plate is connected to the supporting member through anchor bars, sleeves and connecting bolts, and the supporting member includes an upper supporting member and a lower supporting member.

[0015] Furthermore, the connection part between the lower flange plate and the lower supporting member is connected by screws. There is a set of disc spring washers on each set of screws, and a locking nut is provided at the top of the screw. The disc spring can buffer the impact of impact loads; the disc spring can be combined in series, parallel, or series-parallel.

[0016] Furthermore, anchor plates are welded on the embedded parts of the device to increase the tensile strength. The embedded parts include upper embedded parts and lower embedded parts.

[0017] Furthermore, a certain gap is left between the lower flange plate and the lower embedded parts, which can eliminate the height difference caused by problems such as construction and upper structure settlement.

[0018] Furthermore, the guide rails, slide grooves and tensile fasteners can be treated to achieve wear resistance and corrosion resistance through surface electroplating, chemical plating and setting up stainless steel plates and SF-1 materials for grinding.

[0019] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0020] Tensile bearings with buffer devices and seismic isolation rubber bearings are used together in the isolation layer to achieve a synergistic effect. The seismic isolation rubber bearings in the isolation layer provide a large energy dissipation capacity, while the tensile bearings enhance the vertical tensile resistance of the isolation layer. To prevent significant impact caused by gaps in the tensile bearings when subjected to tension, disc springs are used at the connection between the tensile bearings to cushion the impact load.
