Flexible fireproof protection structure of shock insulation rubber support and construction process of flexible fireproof protection structure

Abstract

The invention discloses a flexible fireproof protection structure of a shock insulation rubber support. An upper flange plate and a lower flange plate are arranged between the shock insulation rubbersupport and an upper buttress and between the shock insulation rubber support and a lower buttress; the position, positioned between the upper flange plate and the lower flange plate, of the peripheryof the rubber support is filled with a flexible fireproof heat insulation material; an upper aerogel felt and a lower aerogel felt are attached to the joint of the upper flange plate and the flexiblefireproof heat insulation material and the joint of the lower flange plate and the flexible fireproof heat insulation material; and a composite flexible fireproof heat insulation layer composed of aplurality of layers of overlapped and independent flexible fireproof heat insulation layers is arranged from the outer surface between the upper aerogel felt and the lower aerogel felt to the edge ofthe upper buttress and the edge of the lower buttress and fixed through a self-drilling screw, a steel plate and a high-temperature-resistant steel wire rope. The protection structure can move along with movement of the rubber support, and therefore the rubber support is wrapped in the protection structure all the time, and the fireproof heat insulation function is achieved. In addition, the thickness of a protection layer is small, and other structures are not influenced in a building. In addition, compared with a fireproof plate, cost is low, and the flexible fireproof protection structure is suitable for large-area usage. The design of all connecting parts is unique, and construction, later-period maintenance and demounting are convenient.

Description

technical field [0001] The invention relates to a fireproof protection structure, in particular to a flexible fireproof protection structure for shock-isolation rubber bearings and a construction process thereof. Background technique [0002] Building isolation rubber bearings are products that are alternately stacked and combined with multi-layer rubber and multi-layer steel plates or other materials. With the development of building isolation technology becoming more and more mature, more and more buildings use isolation rubber support. The seismic isolation bearing is generally arranged between the upper and lower piers of the building, as a part of the middle of the load-bearing member, when an earthquake occurs, it reduces the energy input by the earthquake into the superstructure and prevents the structure from collapsing. [0003] According to the regulations for civil buildings in the "Code for Fire Protection Design of Buildings" (GB50016-2014), the fire resistance...
