Abstract
The utility model relates to the technical field of construction and safety production, particularly to a fire-proof door which is of an undercut structure. The fire-proof door comprises a door frame and a door leaf, wherein the door leaf is connected with the door frame through hinges. The door leaf comprises an inner panel and an outer panel, wherein the inner panel is provided with an overlapping edge surface, a side edge surface of the outer panel is bent to clad the overlapping edge surface so as to form an overlapping part; a sinking part is arranged at the position of the door frame, corresponding to the overlapping part, and the overlapping part is closely attached to the sinking part. According to the fire-proof door, the door leaf is formed by bending the inner panel and the outer panel by cladding; the whole section of the door leaf is in a T shape, thereby forming the overlapping edge. The fire-proof door has good effects of fire prevention, smoke prevention, sound insulation and the like by closely attaching the overlapping part to the sinking part of the door frame. Meanwhile, the door leaf can be manufactured by only bending the inner panel and the outer panel, thereby avoiding the appearance of soldered dots, and enhancing the appearance effect of a door body. The fire-proof door is simple in structure, and has high practicality and market popularization value.
Description
Technical field
The utility model relates to building and safety production technique field, especially a kind of labeled door of undercut structure.
Background technology
Labeled door refers to can meet the door that fire stability, integrality and thermal insulation require within a certain period of time; It has more except having the effect of common door the effect that stops fire spreading and flue gas diffusion, can stop within a certain period of time spreading of the intensity of a fire, guarantees evacuating personnel.Existing labeled door generally passes through cold-formed by cold-rolled steel sheet, corrosion resistant plate, mainly by door leaf and doorframe, formed, door leaf and doorframe are hinged by hinge, in door leaf, fill and force refractory thermal insulating material, the surrounding of doorframe is provided with fire proof sealing strip, while closing, the binding face of door leaf and doorframe is realized sealing by weather strip, plays every cigarette, sound insulation, fire-retardant, disconnected hot effect.Yet the labeled door of existing labeled door, especially binding structure (as shown in Figure 1) is general equal, there are the following problems:
1, fire safe seal a directly sticks on the surface of doorframe b, and fire safe seal a is pasted not strongly admittedly, easily comes off;
2, the surrounding of door leaf c is provided with the bound edge d of steel matter, thus, between bound edge c and wainscot e and outer panels f, has gap, easily laying dust, ponding and then cause the rust corrosion of bound edge d, wainscot e, outer panels f;
3, bound edge d need to be screwed, and head of screw exposes, and the surfaces externally and internally joint of bound edge d and door leaf c has gap, and appearance effect is poor.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model be to provide a kind of simple in structure, fire-proof sound insulation is effective, the labeled door of no-welding-spot, good looking appearance.
To achieve these goals, the utility model adopts following technical scheme:
A labeled door, it comprises doorframe and door leaf, and described door leaf and doorframe are connected through the hinge, and described door leaf comprises wainscot and outer panels; On described wainscot, be provided with overlap edge face, after the edge surface bending of described outer panels, coated overlap edge face forms clinch; Position corresponding to clinch on described doorframe is provided with sinking portion, and described clinch fits tightly sinking portion.
Preferably, on described doorframe, with the wainscot place of intersecting be provided with caulking groove, in described caulking groove, be provided with fire safe seal.
Preferably, described doorframe is 1.2-1.5mm by thickness steel sheet rolling or bending and molding.
Preferably, described wainscot and/or outer panels are 0.8-1.5mm by thickness steel sheet bending or roll forming.
Owing to having adopted such scheme, door leaf of the present utility model is Overmolded by wainscot and outer panels bending, the global sections shape of door leaf is T-shape, thereby formed clinch, by with doorframe on fitting tightly of sinking portion make labeled door there is good fire prevention, Smoke prevention and sound insulation texts; Meanwhile, the making of door leaf only need can be embarked on journey by bending interior outer panels, has avoided the appearance of solder joint, has strengthened the appearance effect of door body; It is simple in structure, has very strong practicality and market popularization value.
Accompanying drawing explanation
Fig. 1 is the structural section schematic diagram in prior art with the labeled door of binding structure;
Fig. 2 is the structural section schematic diagram of the labeled door of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 2, a kind of labeled door that the utility model provides, it comprises doorframe 1 and door leaf 2, door leaf 2 is connected through the hinge with doorframe 1; Wherein, door leaf 1 comprises wainscot 3 and outer panels 4, is provided with overlap edge face (the main surface outward with respect to wainscot 3 extends to form) on wainscot 3, is coated overlap edge face, thereby forms clinch 5 after the edge surface bending of outer panels 4; Position corresponding to clinch 5 on doorframe 1 is provided with sinking portion 6, and clinch 5 fits tightly sinking portion 6; Owing to having formed clinch 5 on door leaf 2, make the global sections shape of door leaf 2 roughly be "T"-shaped, by with the coordinating of doorframe 1, can realize good fire prevention, Smoke prevention and sound insulation texts.
Meanwhile, on doorframe 1, be positioned at wainscot 3 places of intersecting of door leaf 2 and be provided with caulking groove 7, in caulking groove 7, be provided with elastomeric fire safe seal 8; So, when door leaf 2 is after opening release, door closer-holder can make door leaf 2 automatically close, three sides of door leaf 2 (hinge side, lock side, top) can move along closing direction, thereby make fire safe seal 8 produce compressive strain and fit with door leaf 2 contact surfaces, and then the interior outside of crack between a door and its frame is cut off; Coordinate again clinch 5 and sinking portion 6, door leaf 2 can be adjacent on doorframe 1, play energy-saving heat preserving (stoping pass through of air-flow that door both sides cause because of the temperature difference), sound insulation (stoping the aerial transmission of sound wave), airtight, and prevent dust (worm), the effect such as rainwater-proof infiltration.Doorframe 1 or door leaf 2 can select corresponding sheet material and method to make moulding according to actual design and service condition, and the preferred mode of the present embodiment is: steel sheet rolling or bending and molding that doorframe 1 is 1.2-1.5mm by thickness; Steel sheet bending or roll forming that wainscot 3 and/or outer panels 4 are 0.8-1.5mm by thickness.
Design based on said structure, the labeled door of the present embodiment has formed the labeled door that is similar to undercut structure, because portion within it does not arrange skeleton, makes the surface of a body there will not be skeleton vestige, and there will not be solder joint, has strengthened the appearance effect of door body; Utilize the clinch 5 and the sinking portion 6 that arrange to coordinate again fire safe seal 8 to make labeled door there is twice isolating and protecting; It is simple in structure, has very strong practicality and market popularization value.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model manual and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
