Novel fire-proof and wind-resistant combined device of isolation rubber support

Abstract

The invention discloses a novel fire-proof and wind-resistant combined device of an isolation rubber support. The combined device comprises the isolation rubber support and connecting plates which are arranged at the upper and lower ends of the isolation rubber support respectively, wherein the periphery of the isolation rubber support is wrapped by a tongued and grooved steel plate; a fire-proof component is arranged at the periphery of the tongued and grooved steel plate. The device has a wind resistance function and a fire proofing function during use at ordinary time; a tongue and groove part of the tongued and grooved steel plate can be sheared by using earthquake force during earthquake, but a fire-proof component can still work normally, and the free horizontal deformation of the isolation rubber support is not obstructed; the purposes of damping and upper structure protection are achieved; after the earthquake ends, the newly machined tongued and grooved steel plate is connected to the upper and lower connecting plates of the isolation rubber support by using bolts, and the corresponding fire-proof component is arranged to newly achieve the wind resistance, fire proofing and isolation functions.

Description

technical field [0001] The invention relates to technical fields such as construction engineering and bridge engineering, and in particular to a novel fireproof and wind-resistant combination device for vibration-isolation rubber bearings applied to building vibration-isolation layers, bridge vibration-isolation layers, and equipment vibration-isolation layers. Background technique [0002] Buildings using seismic isolation rubber bearings can significantly reduce the damage to structures caused by earthquakes and ensure the safety of structures, people and property. It has been well tested in many actual earthquakes. At present, natural vibration-isolation rubber bearings and lead-core vibration-isolation rubber bearings are more maturely used. Natural vibration-isolation rubber bearings are similar to a horizontal linear spring with low stiffness, and generally cannot provide wind resistance, while lead-core vibration-isolation rubber bearings are similar to a horizontal li...

AI Technical Summary

Problems solved by technology

For buildings with a large number of people on the isolation floor, such as underground garages, the building fire protection requirements are relatively high. Generally, it is required to meet Class I fire protection requirements. However, only relying on isolation rubber bearings for fire protection has limited fire protection capabilities and is difficult to meet fire protection requirements.
