Abstract
The invention discloses a kind of fire prevention door closure crack structure, including doorframe and door leaf, described door leaf includes left-hand door fan and right door leaf, left-hand door fan or right door leaf are provided with a lid seam plate, this lid seam plate includes the baffle plate L-shaped with the cover plate being connected outside left-hand door fan or right door leaf and section, 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 plate entirety Z-shape；When door leaf cuts out, baffle plate can be fanned with right door leaf or left-hand door and be close to, with by the gap closing between left-hand door fan and right door leaf.The present invention can effectively prevent fire spreading, flue gas from spreading.
Description
Technical field
The present invention relates to a kind of fire resistant doorsets, particularly relate to a kind of fire prevention door closure crack structure.
Background technology
Fire resistant doorsets importance in fire fighting device, functional, increasingly paid attention to by fire chief department.When fire occurs, fire resistant doorsets passage is the sole outlet of personnel escape, and fire resistant doorsets are to stop the important barrier that the intensity of a fire is stretched, flue gas spreads.Therefore, develop fire resistant doorsets manufacture, application technology, be to ensure that personnel, property, the very important technology of safety.
Fire resistant doorsets are by using materials classification, for fire resistance steel door, steel wood vent, fire-proof wooden door, any kind fire resistant doorsets processing, install, use in all can deform, heat more to deform and the factor such as collision deformation, gap between every fan and door leaf is made to become big or diminish, the most qualified fire resistant doorsets become defective fire resistant doorsets, the gap fire resistant doorsets that diminish are not opened or Guan Buliao, and gap becomes big fire resistant doorsets and do not has prevention fire spreading, flue gas diffusion.
Summary of the invention
For deficiencies of the prior art, it is an object of the invention to how to solve fire resistant doorsets assembling inconvenience, and the problem easily causing because of deformation stoping fire spreading, flue gas to spread, it is provided that a kind of fire prevention door closure crack structure, it is possible to effectively prevent fire spreading, flue gas from spreading.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is such that a kind of fire prevention door closure crack structure, including doorframe and door leaf, described door leaf includes left-hand door fan and right door leaf, it is characterized in that: described left-hand door fan and right door leaf are constituted 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 includes two metallic plates and bonds together between two metallic plates and by two metallic plates；
Being provided with a lid seam plate on left-hand door fan or right door leaf, described lid seam plate includes metal frame and the inorganic fire core material plate being filled in metal frame, and described inorganic fire core material plate is bonded together by resistant to elevated temperatures glue with metal frame；This lid seam plate includes the baffle plate L-shaped with the cover plate being connected outside left-hand door fan or right door leaf and 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 plate entirety Z-shape；When door leaf cuts out, baffle plate can be fanned with right door leaf or left-hand door and be close to, with by the gap closing between left-hand door fan and 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, present invention have the advantage that
1, cross appropriateness can relax the gap between left-hand door fan and right door leaf in processing, installation process, reduce fire resistant doorsets processing, the work difference of installation process coordinates a difficult problem, also temperature and humidity change throughout the year has been solved, make fire resistant doorsets deformation gap excessive leakage cigarette, alter fire, gap diminishes the difficult problem that fire resistant doorsets can not switch.
2, the two sides at fire resistant doorsets is assembled with lid seam plate, it is possible to prevent fire spreading, flue gas from spreading；During breaking out of fire, the lid seam plate in back of the body fire face is owing to being metal sheet and inorganic fire core material plate, and indeformable additional self-strength of self preventing fires also can resist fire resistant doorsets deformation, thus ensures safe and reliable in any state of fire resistant doorsets.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1 left-hand door fan, 2 right door leafs, 3 lid seam plates, 4 frameworks, 5 inorganic fire core material plates, 6 baffle plates.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment: seeing Fig. 1, a kind of fire prevention door closure crack structure, including doorframe and door leaf, described door leaf includes left-hand door fan 1 and right door leaf 2.Described left-hand door fan 1 and right door leaf 2 are constituted 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 includes two metallic plates and bonds together between two metallic plates and by two metallic plates, when being embodied as, this metallic plate uses corrosion resistant plate, and stability is more preferable.
Being provided with a lid seam plate 3 on left-hand door fan 1 or right door leaf 2, described lid seam plate 3 includes metal frame and the inorganic fire core material plate 5 being filled 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 deformation, improve flameproof effect further.This lid seam plate 3 includes the baffle plate 6 L-shaped with the cover plate being connected outside left-hand door fan 1 or right door leaf 2 and 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, makes lid seam plate 3 overall Z-shape；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, with by the gap closing between left-hand door fan 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, it is possible to be effectively reduced fire spreading and the speed of flue gas diffusion.
Described inorganic fire core material plate 5 is ripe prior art, the inorganic fire core material plate 5 as disclosed in the patent (patent No.: ZL201110229683.4) that the applicant has applied for, it is possible to effectively act as the effect of fire-proof and thermal-insulation.
Finally it should be noted that, above example is only in order to illustrate technical scheme rather than restriction technologies scheme, it will be understood by those within the art that, technical scheme is modified or equivalent by those, without deviating from objective and the scope of the technical program, all should contain in the middle of scope of the presently claimed invention.
