Description

A kind of shock insulation rubber bearing flameproof protection device

Technical field

This utility model belongs to structural engineering technical field, relates to a kind of shock insulation rubber bearing flameproof protection dress Put, particularly relate to a kind of flameproof protection device for architectural shock insulation rubber bearing periphery parcel.

Background technology

Along with building subtracts the development of seismic isolation technology, increasing building uses seismic isolation technology, in order to ensure to tie in earthquake The safety of structure is also fully achieved the particular/special requirement using function, and it is a kind of for using seismic isolation technology that building carries out shock-insulating reconstruction Brand-new seismic hardening thinking, this technology, by setting up one layer of Seismic Isolation of Isolation Layer in building bottom, reduces the seismic energy on input top Amount, to reach to improve the purpose of shock resistance of the building, wherein shock insulation rubber bearing is the most commonly used, and is widely used in various Building, is typically during actual application to be directly mounted between upper and lower pier stud shock insulation rubber bearing, becomes shock-insulation building most important Supporting member.

Existing problems are: the most do not set flameproof protection around the shock insulation rubber bearing installed at present, and shock insulation rubber bearing Being to be vulcanized by rubber and steel plate to form, rubber belongs to combustibles, is easy to burning, if rubber support is burnt in the case of meeting fire Bad, its serviceability will be greatly affected, and even results in the total collapse of building, and consequence is hardly imaginable.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of shock insulation rubber bearing flameproof protection device, to overcome Deficiency existing for above-mentioned prior art.

This utility model adopts the technical scheme that: a kind of shock insulation rubber bearing flameproof protection device, including upper pier stud, under Pier stud and be arranged on the shock insulation rubber bearing between upper and lower pier stud, including the lower fire prevention being enclosed in around shock insulation rubber bearing Plate and upper PLASTIC LAMINATED, described lower PLASTIC LAMINATED is arranged on lower pier stud upper end by expansion bolt, and described upper PLASTIC LAMINATED passes through expanding screw Bolt is arranged on pier stud lower end, thus shock insulation rubber bearing surrounds the fireproof jointing sheath forming relative closure, described upper fire prevention Leave space between lower surface and the upper surface of lower PLASTIC LAMINATED of plate, inside described space, be provided with the fire resistant flexible closed in space Cotton.

Its further technical scheme is:

Lower PLASTIC LAMINATED upper surface outside described space is provided with one layer of fire proofing material, and described fire proofing material is that intumescent is prevented Fire material.

Further:

Described upper PLASTIC LAMINATED and lower PLASTIC LAMINATED are autoclaved aerated concrete slab, and its thickness is 5CM～15CM.

Described anti-Pyroxylin is ceramic fiber blanket material, and its thickness is upper PLASTIC LAMINATED and the 1/2 of lower PLASTIC LAMINATED thickness.

Owing to using technique scheme, the one shock insulation rubber bearing flameproof protection device of this utility model has as follows Beneficial effect:

1. due to PLASTIC LAMINATED and lower PLASTIC LAMINATED on having at shock insulation rubber bearing perimeter, thus form the anti-of relative closure Fire protective layer, it is cotton that the gap location between upper and lower PLASTIC LAMINATED is provided with the fire resistant flexible closed in gap, can prevent daily under the conditions of Kindling material enters in shock insulation rubber bearing, additionally arranges one layer of expansion fire-proof material outside gap, in case of fire, works as chance During to high temperature, this material expands rapidly, fills gap and is closed, and prevents flame and heat from jeopardizing shock insulation in entering protection assembly Rubber support, when expansion fire-proof material expands the most completely, the fire resistant flexible cotton inside gap plays the effect of fire-proof and thermal-insulation, Thus playing double-deck flameproof protection effect, flameproof protection effect is more preferable, safer；

2. this flameproof protection device design science, upper and lower PLASTIC LAMINATED both can have been formed between the fireproof jointing sheath of relative closure, It is reserved with gap between upper and lower PLASTIC LAMINATED, does not affect shock insulation rubber bearing in daily and under geological process vertical and level fortune Dynamic；

3. the fire proofing material used is expansion fire-proof material, and upper PLASTIC LAMINATED and lower PLASTIC LAMINATED are steam-pressing aero-concrete Plate, anti-Pyroxylin is ceramic fiber blanket material, has fire prevention, the premium properties such as heat insulation, anticorrosive, environmentally safe, green ring Protect.

Below in conjunction with the accompanying drawings with the embodiment technology to a kind of shock insulation rubber bearing flameproof protection device of this utility model Feature is further described.
