Abstract
The invention discloses a fireproof door seam covering structure. The fireproof door seam covering structure comprises a door frame and door leaves. The door leaves comprise the left door leaf and the right door leaf, a seam covering plate is arranged on the left door leaf or the right door leaf and comprises a covering plate connected with the outer side of the left door leaf or the right door leaf and a baffle of which the section is in an L shape, one side of the baffle is connected with the covering plate, and the other side of the baffle faces the right door leaf or the left door leaf so that the overall seam covering plate can be in a Z shape. When the door leaves are closed, the baffle can be tightly attached to the right door leaf or the left door leaf so that the seam between the left door leaf and the right door leaf can be closed. Fire can be effectively prevented from spreading, and smoke can be effectively prevented from dispersing.
Description
Technical field
The present invention relates to a kind of labeled door, particularly relate to a kind of fire prevention door closure crack structure.
Background technology
The importance of labeled door in fire fighting device, functional, be more and more subject to the attention of fire chief department.When fire occurs, labeled door passage is the sole outlet of personnel escape, and labeled door stops the important barrier that the intensity of a fire is stretched, flue gas spreads.Therefore, develop labeled door manufacture, application technology, be guarantee personnel, property, safe very important technology.
Labeled door is by using materials classification, for fire resistance steel door, steel wood vent, fire-proof wooden door, any class labeled door in processing, install, use in all can be out of shape, heat more will be out of shape and the factor such as collision deformation, make every fan gap between door leaf become large or diminish, originally qualified labeled door becomes defective labeled door, the gap labeled door that diminishes is not opened or Guan Buliao, and gap becomes large labeled door and do not have and stop fire spreading, flue gas diffusion.
Summary of the invention
For prior art above shortcomings, the object of the invention is to how to solve labeled door assembling inconvenience, and the easy problem causing stoping fire spreading, flue gas to spread because of distortion, a kind of fire prevention door closure crack structure is provided, can effectively prevents fire spreading, flue gas from spreading.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is such: a kind of fire prevention door closure crack structure, comprise doorframe and door leaf, described door leaf comprises left-hand door fan and right door leaf, it is characterized in that: described left-hand door fan and right door leaf are formed by the inorganic fire core material plate in framework and framework, described framework by composite metal plate punch forming, the bonding agent that this composite metal plate comprises two metal sheets and bonds together between two metal sheets and by two metal sheets;
Left-hand door fan or right door leaf are provided with a lid seam plate, and described lid seam plate comprises metal frame and is filled in the inorganic fire core material plate in metal frame, and described inorganic fire core material plate and metal frame are bonded together by resistant to elevated temperatures glue; This lid seam plate comprises the cover plate fan with left-hand door or be connected outside right door leaf and the L-shaped baffle plate of section, and the side of this baffle plate is connected with cover plate, and opposite side fans direction towards right door leaf or left-hand door, makes lid seam slab integral be Z-shaped; When door leaf cuts out, baffle plate can be fanned with right door leaf or left-hand door and be close to, left-hand door to be fanned the gap closing between right door leaf.
Further, described cover plate has the convex edge protruding from baffle plate, and the width of described convex edge is less than or equal to the gap between left-hand door fan and right door leaf.
Compared with prior art, tool of the present invention has the following advantages:
1, cross in processing, installation process the gap can appropriate relaxed between left-hand door fan with right door leaf, reduce a work difference cooperation difficult problem for labeled door processing, installation process, also temperature and humidity change has throughout the year been separated, make labeled door be out of shape the excessive leakage cigarette that gaps, alter fire, gap diminishes labeled door can not the difficult problem of switch.
2, lid seam plate is all installed on the two sides of labeled door, can have prevented fire spreading, flue gas from spreading; During breaking out of fire, carry on the back the lid seam plate in fiery face owing to being metal sheet and inorganic fire core material plate, the indeformable additional self-strength of self fire prevention also can resist labeled door distortion, thus ensures safe, reliable in any state of labeled door.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-left-hand door is fanned, 2-right door leaf, 3-lid seam plate, 4-framework, 5-inorganic fire core material plate, 6-baffle plate.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment: see Fig. 1, a kind of fire prevention door closure crack structure, comprise doorframe and door leaf, described door leaf comprises left-hand door fan 1 and right door leaf 2.Described left-hand door fan 1 and right door leaf 2 are formed by the inorganic fire core material plate 5 in framework 4 and framework 4, described framework 4 is by composite metal plate punch forming, the bonding agent that this composite metal plate comprises two metal sheets and bonds together between two metal sheets and by two metal sheets, during concrete enforcement, this metal sheet adopts corrosion resistant plate, and stability is better.
Left-hand door fan 1 or right door leaf 2 are provided with a lid seam plate 3, and described lid seam plate 3 comprises metal frame and is filled in the inorganic fire core material plate 5 in metal frame, and described inorganic fire core material plate 5 is bonded together by resistant to elevated temperatures glue with metal frame; Effect of heat insulation can be improved further, thus avoid causing the situation such as fire spreading, flue gas diffusion to occur because of door leaf distortion, improve flameproof effect further.This lid seam plate 3 comprises cover plate that fan with left-hand door and be connected outside 1 or right door leaf 2 and the L-shaped baffle plate 6 of section, and the side of this baffle plate 6 is connected with cover plate, and opposite side fans 1 direction towards right door leaf 2 or left-hand door, and it is Z-shaped for making lid seam plate 3 overall; When door leaf cuts out, baffle plate 6 can be fanned 1 with right door leaf 2 or left-hand door and be close to, left-hand door to be fanned the gap closing between 1 and right door leaf 2.
Described cover plate has the convex edge protruding from baffle plate 6, and the width of described convex edge is less than or equal to the gap between left-hand door fan 1 and right door leaf 2; Thus the gap outside door leaf is blocked, when inside cover seam plate 3 lost efficacy, the speed of fire spreading and flue gas diffusion effectively can be reduced.
Described inorganic fire core material plate 5 is ripe prior art, and the inorganic fire core material plate 5 disclosed in the patent (patent No.: ZL201110229683.4) that the applicant has applied for, can play the effect of fire-proof and thermal-insulation effectively.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to technical scheme of the present invention or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present invention.
