Embodiment 1

[0043] Embodiment one sees figure 1 , 3 As shown in -5, a kind of earthquake-proof and fire-proof structure comprises a shock-isolation layer upper plate 1, a shock-isolation layer lower plate 2, and is located between the earthquake-isolation layer upper plate 1 and the shock-isolation layer lower plate 2 and enclosed in the shock-isolation layer The vertical fireproof board 3 around the floor space and the fireproof board blocking device 4, the middle part of the fireproof board 3 is disconnected to form a horizontal seismic shift joint 5 around the shock-isolation layer space, and the fireproof board is blocked The device 4 is fixed in the seismic movement joint 5 , and the fireproof board sealing device 4 is adapted to the size of the seismic movement joint 5 .

[0044] The earthquake staggered joint 5 divides the fireproof board 3 into an upper fireproof board 3.1 and a lower fireproof board 3.2,

[0045] An upper connecting angle steel 6 is provided between the upper par...

Embodiment 2

[0060] Embodiment two see Figure 2-5 As shown, the difference from Embodiment 1 is that the upper plate 1 of the earthquake-isolation layer is the upper pier of the earthquake-isolation bearing, and the lower plate 2 of the earthquake-isolation layer is the lower pier of the earthquake-isolation bearing, ensuring that each earthquake-isolation The support shall be equipped with the earthquake-proof and fire-proof structure.

[0061] The construction method of the earthquake-proof fireproof structure of the present embodiment, the construction steps are as follows:

[0062] Step 1, determine the net height of the seismic isolation support: first determine the net height between the upper pier of the seismic isolation support and the lower pier of the seismic isolation support, and design the fireproof board 3 and the fireproof board sealing device 4 through the net height The size, installation position and installation height make the fireproof board 3 and the fireproof boar...

Abstract

The invention discloses a shock-insulating fireproofing structure and a construction method thereof. The shock-insulating fireproofing structure comprises a shock-insulating layer upper plate, a shock-insulating layer lower plate, vertical fireproof plates and fireproof plate blocking devices, wherein the vertical fireproof plates are positioned between the shock-insulating layer upper plate and the shock-insulating layer lower plate and are surrounded around the space of a shock-insulating layer; the middle parts of the fireproof plates are disconnected to form a horizontal earthquake diastrophism seam which travels around a circle of the space of the shock-insulating layer; each fireproof plate blocking device is fixedly arranged inside the earthquake diastrophism seam and is adaptive to the size of the earthquake diastrophism seam. The construction method of the shock-insulating fireproofing structure comprises the following steps: (1) determining the clear height of the shock-insulating layer and designing the size, installation position and installation height of the fireproof plates and the fireproof plate blocking devices according to the clear height; (2) mounting an upper layer fireproof plate and a lower layer fireproof plate on line; pressing the fireproof plate blocking device into the earthquake diastrophism seam. The shock-insulating fireproofing structure disclosed by the invention is capable of improving the fire resistance of the shock-insulating layer and a shock-insulating strut so as to ensure that a shock-insulating building is capable of farthest playing an effect when earthquake happens, and thus an expected effect of a shock-insulating building can be realized.

Description

technical field [0001] The invention belongs to the field of building protection, in particular to a fireproof structure of a building shock-isolation support or a shock-isolation layer and a construction method thereof. Background technique [0002] Seismic isolation building refers to the use of seismic isolation technology to install seismic isolation devices at the base of the building or at a certain position to form a seismic isolation layer, which isolates the upper structure from the lower foundation, so as to consume seismic energy and avoid or reduce earthquakes. The energy is transmitted to the upper part, which can more effectively guarantee the safety of the upper structure, internal personnel and equipment. [0003] Seismic isolation devices usually use seismic isolation bearings, which are rubber products and are extremely important components in seismic isolation buildings. However, its fire resistance is poor, and after a fire occurs, it will cause unimagin...
