Sprayed fire proofing coating.Patent of invention point is the lightweight floor panel structure for designing a kind of fire resisting that can bear a heavy burden for a long time, the wound of the structure
New point is that overall structure fire resistance period is long；Overall structure is stablized, and weight bearing ability is strong；Overall structure lightweight；Overall structure assembly
Simply, convenient for construction.It is distinct with patent searching, no risk of infringement.How to guarantee lightweight, stable structure and be convenient for peace
In the case where dress, the strong Integral floor structure of fire resistance is designed, the difficult point of design is become.
Summary of the invention
The purpose of the present invention is primarily directed to above-mentioned the problems of the prior art, with providing a kind of lightweight of fire resisting of bearing a heavy burden
Plate, overall structure fire resistance period are long；Overall structure is stablized, and weight bearing ability is strong；Overall structure lightweight；Overall structure assembly letter
It is single, convenient for construction.
In order to solve the above technical problems, the lightweight floor of weight bearing fire resisting provided by the invention, including it is layed in vehicle
Floor cloth above bottom plate, it is characterised in that: also there is the fire-proof plate being fixed below vehicle floor, the fire-proof plate and vehicle
Cold-proof materials are equipped between bottom plate, the left and right sides of the fire-proof plate and the edge beam of underframe of vehicle are fixed.
The lightweight floor of above-mentioned weight bearing fire resisting, particularly suitable for rail vehicle.
The present invention protects a kind of rail vehicle, it is characterised in that: the lightweight floor with above-mentioned weight bearing fire resisting.
The invention further relates to the installation methods on above-mentioned floor: steps are as follows:
Step 1 installs fire prevention board mount in the lower surface of vehicle floor；
The lower surface laying cold-proof materials of step 2, vehicle floor；
Step 3 installs fire-proof plate by fire prevention board mount, and cold-proof materials are prevented between fire-proof plate and the lower surface of vehicle floor
It rivets and fixes with the edge beam of underframe of vehicle at left and right sides of fiery plate；
The upper surface laying floor cloth of step 4, vehicle floor.
Bottom plate of the present invention is mainly composed of five kinds of main materials of four-layer structure, from top to bottom respectively rubber floor covering
Cloth-aluminum alloy bodywork profile-ceramic fibre-stainless steel fire-proof plate, in addition in aluminum alloy bodywork profile side bar part direct spraying
Fireproof coating.
The assembling form on the lightweight floor of present invention weight bearing fire resisting are as follows: completely spread using certain thickness ceramic fibre material
Under hull bottom plate；Ceramic fibre lower surface is mated formation certain thickness stainless steel fire-proof plate, and fire-proof plate is fastened by bolts pre-
It is embedded on the fire prevention board mount of car body floor lower surface, is fixed with car body side bar lap-joint with rivet；In aluminum alloy bodywork side bar
Lower surface area sprays certain thickness fireproof coating, which can expand in the case where meeting fiery high-temperature condition, isolation flame and
The quick transmitting of heat.
Fireproof floorboard of the present invention has the following characteristics that
1, overall structure fire resistance period is long；
2, overall structure is stablized, and weight bearing ability is strong；
3, overall structure lightweight；
4, overall structure assembly is simple, convenient for construction.
