Embodiment Construction

[0017] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific examples are given in conjunction with the drawings, and detailed descriptions are made as follows.

[0018] Such as Figure 1~2 As shown, a variable-rigidity wind-resistant support for a seismic isolation layer includes an upper connecting steel plate 1 arranged above and a lower connecting steel plate 2 arranged below, between the upper connecting steel plate 1 and the lower connecting steel plate 2 Several wind-resistant steel plates 3 are arranged at intervals. The wind-resistant steel plates 3 are in an X shape with wide upper and lower ends and retracted in the middle. The front and rear sides of the central retracted part of the wind-resistant steel plate 3 are provided to form a weak yield. The arc-shaped recess 301 of the surface.

[0019] In the embodiment of the present invention, both the left and right sides of the wind-resistant ste...

Abstract

The invention relates to a variable stiffness wind-resistant support for a shock-isolation layer, which comprises an upper connecting steel plate arranged above and a lower connecting steel plate arranged below, and several Wind-resistant steel plate, the wind-resistant steel plate is X-shaped with wide upper and lower ends and a retracted middle part, and the front and rear sides of the central retracted part of the wind-resistant steel plate are provided with circular arc surface notches for forming a weak yield surface ; The present invention also relates to an installation method for variable stiffness wind-resistant bearings used in shock-isolation layers. The structure design of the present invention is simple and reasonable, low in cost and superior in performance. It adopts the form of independent wind-resistant support, does not increase the installation difficulty of the original shock-isolation support, is convenient to disassemble, and makes full use of the characteristics of steel. To achieve the purpose of wind resistance without affecting the effect of seismic isolation, it can effectively solve the problem of wind resistance of seismic isolation buildings, and has broad application prospects.

Description

Technical field [0001] The invention relates to a variable-rigidity wind-resistant support for a seismic isolation layer and an installation method thereof. Background technique [0002] There are two main shortcomings in the existing technology. First, most of the technical measures consider adding wind-resistant components outside the seismic isolation support, but the current fire protection design of most seismic isolation bearings is to cover the periphery of the support with fireproof materials. Obviously this The two technical methods conflict in space utilization, which increases the difficulty of installing the seismic isolation support. 2. Another part of the technical means adopts independent wind-resistant bearings, but due to structural problems, it fails to solve the problem of reusing the wind-resistant bearings when they are damaged. Summary of the invention [0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present in...
