Abstract
The utility model relates to a fireproof door, in particular to a fireproof door allowing bi-directional opening. The fireproof door comprises an outer door frame, an inner door frame and a door leaf. A front hinge and a back hinge are installed on the front face and the back face located on one side edge of the inner door frame respectively. The back face of the inner door frame is hinged to one side of the door leaf through the back hinge, and the front face of the inner door frame is hinged to one side of the outer door frame through the front hinge. The front hinge and the back hinge are contrary in opening and closing direction. The fireproof door allowing the bi-directional opening has the advantages that on the premise that the fireproof airtight requirement of the gap between the door frames and the door leaf of the fireproof door, the fireproof door can be made to be opened in a bi-directional mode, the difficult problem that in the prior art, a single door leaf of a fireproof door can only be opened in an unidirectional mode is solved, meanwhile, the structure is simple, and cost is low.
Description
Technical field
The utility model relates to labeled door, is specifically related to a kind of labeled door of bidirectional opening.
Background technology
Labeled door is the important component part of structural fire protection measure, in building, fire escape all need arrange labeled door in fire compartmentation place,, in case when guaranteeing the breaking out of fire accident, labeled door can be convenient to evacuating personnel and pass through, can intercept again the condition of a fire after closing by spread to contiguous fire compartmentation by disaster area.According to Code for fire protection design of buildings, labeled door should be the flat opening door, should have function of self closing; Evacuating the labeled door of purposes should open to evacuating direction, and closing rear requirement can fire-proof smoke-proof, and the satisfied fire prevention time is not less than the fire endurance time requirement of regulation.
Due to labeled door except can be fire-resistant, radiation-inhibiting is warm and heat by conduction, also require crack between a door and its frame that good fire prevention airtight performance is arranged, invade to stop flue gas.So between fireproof door leaf and doorframe, fire proof sealing strip need be set, this requirement makes the rotating distance of fireproof door leaf be subject to fire proof sealing strip blend stop on doorframe, be difficult to accomplish to cross over 180 degree bidirectional openings of doorframe, the actual common labeled door that puts into operation is unidirectional opening ways for a long time.
Make thus some places, as the labeled door between electrical room, the labeled door of fire compartmentation place in the structure such as tunnel, pipe gallery, and similar adjacent fire compartmentation need evacuate the residing labeled door of the field of direction etc. each other, requirement that must bidirectional opening is difficult to realize.According to existing labeled door technology, though or can can't meet the airtight requirement of fire prevention of crack between a door and its frame gap by bidirectional opening, or in fire compartmentation place, the two opposite unidirectional labeled doors of fan opening direction are set, and increase on foot the building area of passage.So for above-mentioned occasion is designed a kind of airtight requirement of fire prevention that can meet gap between the doorframe door leaf, labeled door that again can bidirectional opening is very necessary.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, and a kind of labeled door of bidirectional opening is provided, and this labeled door is installed respectively positive hinge and anti-hinge by the obverse and reverse place at interior doorframe, so that door leaf is inwardly realized outwards bidirectional opening.
The utility model purpose realizes being completed by following technical scheme:
A kind of labeled door of bidirectional opening, it is characterized in that described labeled door comprises exterior door frame, interior doorframe and door leaf, wherein be positioned at the obverse and reverse place of a side of described doorframe, be separately installed with positive hinge and anti-hinge, the reverse side of described interior doorframe is articulated and connected by anti-hinge and described door leaf one side, the front of described interior doorframe and described exterior door frame one side are articulated and connected by positive hinge, the folding opposite direction of described positive hinge and described anti-hinge.
Be provided with the lid seam plate of extension to described door leaf at the front of described interior doorframe peripheral edge portion, with spacing to described door leaf.
Being provided with outside fire prevention between described lid seam plate and described door leaf expands airtight.
Being provided with inboard fire prevention between the reverse side of described interior doorframe and described exterior door frame expands airtight.
Be provided with inboard door closer between the top rail reverse side of described door leaf reverse side upper edge and described interior doorframe.
Be provided with outside door closer between the top rail front of described exterior door frame and the top rail front of described interior doorframe.
The utility model has the advantages that, under the prerequisite of the airtight requirement of fire prevention in gap between the doorframe that meets labeled door and door leaf, can make the labeled door bidirectional opening, solved the difficult problem that labeled door simple gate fan in the past can only unidirectional unlatching, simultaneously simple in structure, cost is low.
