Fireproof corrosion-resistant shock insulation support

Abstract

The invention provides a fireproof corrosion-resistant shock insulation support. The fireproof corrosion-resistant shock insulation support comprises an upper structure bearing platform, a lower foundation bearing platform, a lead core laminated rubber shock insulation support body, an outer wrapping rubber layer, an outer ring protection rubber layer, a fireproof coating layer, a flexible filling material and a connecting steel plate, Wherein the outer rubber wrapping layer is wrapped around the periphery of the lead core laminated rubber shock insulation support body and is connected with the connecting steel plate in a vulcanization mode, the outer ring protection rubber layer is arranged on the periphery of the outer rubber wrapping layer to form a ring shape and is connected with the outer rubber wrapping layer in a vulcanization mode, the space between the outer rubber wrapping layer and the outer ring protection rubber layer is filled with the flexible filling material, and the surface of the connecting steel plate is coated with the fireproof coating layer. The fireproof corrosion-resistant shock insulation support has the beneficial effects that the horizontal shock insulation performance of the lead core laminated rubber shock insulation support body is not affected, the vertical bearing capacity of a traditional lead core laminated rubber shock insulation support can be effectively protected in a fire disaster, and the deformation capacity of the lead core laminated rubber shock insulation support body in the horizontal direction is not affected.

Description

[0001] The invention belongs to the technical field of a fire-proof, corrosion-resistant and shock-isolation support which has no influence on the horizontal shock-isolation effect, and in particular relates to a fire-proof, corrosion-resistant and shock-isolation support. Background technique [0002] Vibration is a common phenomenon in nature. In many engineering environments, vibration is considered to be an unfavorable factor. In order to protect instruments, equipment and other objects from damage caused by vibration, more and more vibration isolation devices appear on the market. At present, most The horizontal isolation of the installation is achieved through lead laminated rubber bearings. However, the rubber used in traditional lead-core laminated rubber bearings is flammable. Once burned, the rubber bearing will directly lose its vertical bearing capacity and horizontal shock isolation capacity. Nowadays, many houses that use seismic isolation design will design the ...

Problems solved by technology

[0003] At present, there are many fireproof, corrosion-resistant and shock-isolation bearings on the market: the bearings that simply use fireproof paint as the fireproof layer have certain fireproof ability, but fireproof paint, as a kind of brittle coating, must have certain fireproof ability With a certain thickness, when the support produces lateral displacement, the paint will inevitably crack and disintegrate, and naturally it does not have fire resistance; considering the deformation capacity of the support under fire, there are also supports that use a flexible fireproof cover as a fireproof layer , but the sealing of the connection between the ordinary fire cover and the upper and lower plates of the support is a problem. Without good sealing performance, the fire protection ability of the fire cover cannot be well exerted
