Problems solved by technology

In addition, for large-span buildings, high-rise and super high-rise buildings, displacement is easily caused by wind, thereby reducing the performance and life of the rubber bearing
Although the existing tensile limiter can play a tensile effect, it will affect the horizontal vibration isolation effect of the vibration isolation rubber bearing to a certain extent, and the cost of some structures is extremely high

Embodiment 1

[0029] Such as figure 1 , figure 2 and image 3 A composite rail-type tension-proof rubber bearing is shown, including an upper flange plate 12 , a lower flange plate 11 , a tension-limiting device 4 , a transverse guide rail 31 , a longitudinal guide rail 32 and a vibration-isolation rubber bearing 2 . The shock-isolation rubber bearing is type I or type II, and the upper and lower flange plates are rectangular and perpendicular to each other. There are two transverse guide rails 31 and two longitudinal guide rails 32, which are in the shape of a dovetail groove. The two ends are sealed by welding to limit the chute from sliding out of the guide rail. Each is parallelly fixed to the edge of the inner surface of the lower flange plate 11 and the upper flange plate 12 by bolts, and the height of the bolts does not exceed the thickness of the flange plate. The tension limiting device 4 includes an upper connection part 43 , a limit box 42 and a lower connection part 41 . T...

Embodiment 2

[0031] Such as Figure 4 As shown, the difference between it and Embodiment 1 is that the shock-absorbing rubber bearing is Type II, the tensile limiting device 4 is placed upside down, and the limiting box 42 is circular.

[0032] In daily use, the friction between the upper and lower connecting parts and the guide rail can achieve a certain wind load resistance effect. When the earthquake comes, the upper and lower connecting parts of the limit device slide along the longitudinal and transverse guide rails respectively, without affecting the vibration isolation rubber support. The horizontal isolation effect of the seat, if the vertical earthquake is obvious, the limit box 42 can play the role of vertical tension limit.

Abstract

The invention relates to the technical field of building seismic isolation, in particular to a composite guide rail type tensile seismic isolating rubber support. The support comprises an upper flange plate, a lower flange plate and a seismic isolating rubber support body and further comprises two transverse guide rails, two longitudinal guide rails and a tensile limiting device. The transverse guide rails and the longitudinal guide rails are mounted on the edge of the inner surface of the upper flange plate and the edge of the inner surface of the lower flange plate respectively in parallel. The tensile limiting device comprises an upper connecting part, a limiting box and a lower connecting part and is arranged in central symmetry about the seismic isolating rubber support body. The upper connecting part and the lower connecting part are in nested connection with the longitudinal guide rails and the transverse guide rails respectively. The open end of the limiting box and the upper connecting part are in nested connection, and the opposite face closed end of the limiting box is fixedly connected with the lower connecting part. According to the support, the seismic isolating rubber support body and the tensile limiting device are assembled to be used, guide rail design is utilized, and the synergistic effect of the seismic isolating rubber support body and the tensile limiting device is achieved. The horizontal seismic isolating effect of the seismic isolating rubber support body is not influenced, meanwhile certain wind vibration can be resisted, and the vertical tensile capacity of the support is improved.

Description

technical field [0001] The patent of the invention relates to the technical field of building shock isolation, in particular to a composite guide rail type tensile shock-isolation rubber bearing. Background technique [0002] The working principle of the rubber isolation bearing is to set the rubber isolation bearing between the superstructure and the foundation surface of the building, or between the interlayer structures, and through the effective work of the isolation bearing, limit and reduce the impact of seismic waves The input of the superstructure, and control the seismic effect of the superstructure and the deformation of the isolation support, so as to reduce the seismic response of the entire building and achieve the purpose of earthquake resistance. [0003] In recent years, base-base isolation has been gradually promoted and applied in high-rise and super high-rise buildings. Due to the large overturning moment generated by the horizontal seismic force of high-...
