Example Embodiment

[0031] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The specific embodiments described are only for explaining the present invention and are not intended to limit the present invention.

[0032] The present invention provides a fire protection device for building vibration isolation rubber bearings, such as figure 2 with Figure 4 As shown, it includes a heat-insulating fire ring arranged between the upper column 1 and the lower column 2 and located on the outer periphery of the shock-isolating rubber support 8. Among them, the structure of the vibration isolation rubber bearing 8 is as figure 1 with image 3 Shown, where, figure 1 Shown is the structure of the lead-free vibration isolation rubber bearing involved in Example 1. image 3 Shown is the structure of the lead-containing shock-isolating rubber bearing in the second embodiment.

Abstract

The invention discloses a fire-proof protecting device of a shock-insulation rubber supporting seat. The fire-proof protecting device comprises upper heat-insulation profiles, lower heat-insulation profiles, aluminum silicate fiber blankets connecting pieces and fire-proof blocking materials. The fire-proof blocking materials are adhered between the contact faces of the upper heat-insulation profiles and upper layer columns. The lower heat-insulation profiles are arranged on the top faces of lower layer columns in a masonry mode through fire-proof adhesives. The fire-proof blocking materials are adhered between the upper heat-insulation profiles and the lower heat-insulation profiles. The spaces between the upper heat-insulation profiles and the shock-insulation rubber supporting seat as well as between the lower heat-insulation profiles and the shock-insulation rubber supporting seat are filled with the aluminum silicate fiber blankets. Through a fire-proof protecting construction method, good fire-proof protecting for the shock-insulation rubber supporting seat can be achieved, it can be ensured that fire-proof protecting is not destroyed during shock-insulation supporting seat deformation, and meanwhile the method has the advantages of being convenient to operate and wide in application range.

Description

technical field [0001] The invention relates to a fire protection structure, in particular to a fire protection system of a building shock isolation device. Background technique [0002] Building seismic isolation technology is to set a seismic isolation layer composed of seismic isolation bearings on a certain floor of the building, usually between the superstructure and the foundation (or lower) structure of the building, so that the superstructure of the building can be separated from the foundation. ", used to change the vibration characteristics of the structural system, prolong the structural period, increase the structural damping, consume most of the seismic energy through the horizontal large deformation movement of the isolation layer, reduce the input of seismic energy to the upper structure, and effectively reduce the damage caused by the earthquake to the upper structure. Acceleration response, reduce the interstory shear force and corresponding shear deformatio...
