Abstract
The utility model is related to a kind of bridge fire resistant doorsets, including door-plate and doorframe absolutely, and the door-plate is installed on the doorframe, and the door-plate is oppositely arranged including two, door leaf interconnected；Anti-fire door core board is accompanied in described two door leafs, and the edge of described two door leafs all has towards the bending inside door-plate, and cavity is formed inside door-plate, fire-proof and thermal-insulation item is filled between two be oppositely arranged cavity.Above-mentioned bridge cut-off fire resistant doorsets have bridge cutoff type structure and built-in anti-fire door core board, therefore have good insulation blocking effect.Further, since door-plate bottom setting is there are two fire safe seal, fire prevention isolation performance more preferably, while also improving the soundproof effect of the bridge cut-off fire resistant doorsets, even if single layer, which is damaged, nor affects on the use overall effect of the bridge cut-off fire resistant doorsets.
Description
Technical field
The utility model relates to door fields, and in particular to a kind of bridge cut-off fire resistant doorsets.
Background technique
Fire prevention is to show a very severe in construction projects job, and fire resistant doorsets are very heavy in building fire protection engineering
The a part wanted.Fire resistant doorsets are mostly installed at the positions such as the channel of inlet and outlet, and the work that insulation blocking can be played when fire occurs
With.Fireproof door structure in the prior art is simple, can not provide enough insulation blocking effects.
Utility model content
The purpose of this utility model is to provide a kind of bridge cut-off fire resistant doorsets, are capable of providing enough insulation blocking effects.
In order to solve the above technical problems, providing a kind of bridge cut-off fire resistant doorsets, including door-plate and doorframe, institute in the utility model
It states door-plate to be installed on the doorframe, and the door-plate is oppositely arranged including two, door leaf interconnected；Described two door leafs
In accompany anti-fire door core board, and the edge of described two door leafs all has towards the bending inside door-plate, is formed inside door-plate
Cavity is filled with fire-proof and thermal-insulation item between two cavitys being oppositely arranged.
Optionally, the cross section of the bending is rectangle.
Optionally, the door leaf is galvanized steel plain sheet door leaf.
Optionally, the anti-fire door core board includes at least one of magnesium oxide core veneer and Pearl stone drying plate.
Optionally, further include door closer, the top of the door-plate is set, one end is connected to doorframe, and one end is connected to institute
State door-plate.
Optionally, further include hinge for fireproof, a side of the door-plate is set, for the door-plate to be connected to door
Frame.
It optionally, further include Fire-proof lock, in setting to the door-plate.
Optionally, further include fire safe seal, be set to the door-plate bottom.
Optionally, including two fire safe seals, it is arranged in parallel in the door-plate bottom.
Above-mentioned bridge cut-off fire resistant doorsets have bridge cutoff type structure and built-in anti-fire door core board, therefore there is good isolation to protect
Shield effect.Further, since door-plate bottom setting is there are two fire safe seal, fire prevention isolation performance more preferably, is gone back simultaneously
Improve the soundproof effect of the bridge cut-off fire resistant doorsets, though single layer be damaged nor affect on the bridge cut-off fire resistant doorsets using whole
Body effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of bridge cut-off fire resistant doorsets described in a kind of specific embodiment of the utility model.
Fig. 2 is that the door-plate bottom setting two of bridge cut-off fire resistant doorsets described in a kind of specific embodiment of the utility model is anti-
The structural schematic diagram of fiery sealing element.
Specific embodiment
Below in conjunction with the drawings and specific embodiments to the utility model proposes a kind of grease hinge make further it is detailed
Explanation.
Referring to Fig. 1, being the structural schematic diagram of the bridge cut-off fire resistant doorsets.In the specific embodiment, the bridge cut-off
Fire resistant doorsets include door-plate and doorframe, and the door-plate is installed on the doorframe, and the door-plate includes two and is oppositely arranged, mutually
The door leaf 101 of connection；Anti-fire door core board is accompanied in described two door leafs 101, and the edge of described two door leafs 101 all has court
To the bending 103 inside door-plate, cavity 104 is formed inside door-plate, is filled with fire prevention between two cavitys 104 being oppositely arranged
Heat insulating strip 105.
In a specific embodiment, the cross section of the bending 103 is rectangle.In other specific embodiments,
The cross section of the bending 103 can also be other figures, including circle, diamond shape etc..As long as the shape of the bending 103 meets energy
Form the demand of cavity 104.
In a specific embodiment, the door leaf 101 is galvanized steel plain sheet door leaf 101.In other specific embodiments
In, the material of the door leaf 101 may be other be coated with fireproof coating wooden door, metallic doors etc., can as needed into
The specific setting of row.
In a specific embodiment, the anti-fire door core board include in magnesium oxide core veneer and Pearl stone drying plate at least
It is a kind of.In other specific embodiments, the anti-fire door core board further includes the fire proofing materials such as frothing foam.
In a specific embodiment, bridge cut-off fire resistant doorsets further include door closer, and the top of the door-plate, one end is arranged in
It is connected to doorframe, one end is connected to the door-plate.By the way that door closer is arranged, keep the bridge cut-off fire resistant doorsets normally closed, therefore have more
Good isolation effect.
In a specific embodiment, bridge cut-off fire resistant doorsets further include hinge for fireproof, and a side of the door-plate is arranged in,
For the door-plate to be connected to doorframe.It further include Fire-proof lock, in setting to the door-plate.
In a specific embodiment, bridge cut-off fire resistant doorsets further include fire safe seal, are set to the door-plate bottom.Please
