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, a

Embodiment 1

[0031] see figure 1 , the technical solution provided by the present invention is: a fire-proof, corrosion-resistant and shock-isolation bearing comprising: an upper structure bearing platform 1, a lower foundation bearing platform 2, a fireproof coating 3, bolts 4, double-layer fireproof rubber 6, lead core laminated rubber Bearing 7, wherein, the double-layer fireproof rubber 6 on the outside of the lead core laminated rubber bearing 7 body is a hollow annular cylinder, which is enveloped on the periphery of the rubber bearing 7 body, and the lead core laminated rubber bearing 7 The outer covering rubber and the rubber layer on the outside of the outer covering rubber are all fire-resistant rubber; on the upper and lower sides of the lead core laminated rubber bearing 7 body, the steel surface is also coated with fire-resistant paint 3. Under the premise of providing a certain fire-proof ability, the hollow double-layer Fireproof rubber 6 will not affect the horizontal defor...

Embodiment 2

[0033] see figure 2 , on the basis of Embodiment 1, this embodiment also includes the following content, the flexible material 5 is filled in the hollow double-layer fireproof rubber 6, and the flexible material 5 is asbestos, because the double-layer fireproof rubber 6 only serves as the first fireproof The layer does not need a very large thickness, and has no effect on the horizontal deformation capacity of the lead core laminated rubber bearing 7; the cavity inside the double-layer fireproof rubber 6 is filled with a flexible fireproof material 5, such as asbestos, as the second fireproof layer, Provide adequate fire resistance.

Embodiment 3

[0035] see image 3 , on the basis of Embodiment 2, this embodiment also includes the following content: the top and bottom of the double-layer fireproof rubber 6 are set to be connected to form a hollow ring-shaped cylinder with a closed outer surface, and the interior is filled with flexible fireproof materials 5, such as asbestos, when using the vulcanization process to connect the double-layer fire-resistant rubber 6 and the lead-core laminated rubber bearing 7 body, the design of the top and bottom connection can make the double-layer fire-resistant rubber 6 and the lead-core laminated rubber bearing The connection of 7 is tighter and the sealing performance is better.

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 ...
