Abstract
The utility model discloses a novel structure steel insulates against heat and prevents fire door has two door leafs, and the line sewn down the back of a jacket face of this two door leaf passes through an inside and outside right angle component ladder right angle structure of looks adaptation, it is used for the lid seam board of enclosing cover in the two door leaf lines sewn down the back of a jacket respectively to be equipped with one on the not homonymy side of this two door leaf. The line sewn down the back of a jacket structural design who prevents next door leaf of fire door adopts middle lapped ladder right angle structure to set up the lid in relative both sides and stitch the board, constitute two ladder structural style, strengthened piercing through of separation burning things which may cause a fire disaster greatly, and fire prevention, smoke protection effect. The lid stitches the board and comprises the two -layer PLASTIC LAMINATED of zinc -plated cold -rolled steel sheet parcel better, and it has higher heat -proof quality and penetration capacity that can the greatly reduced burning things which may cause a fire disaster, prevents effectively that the burning things which may cause a fire disaster from passing the door leaf line sewn down the back of a jacket, has strengthened the fire behavior who prevents fire door. Can further add second fire prevention expandable sealing strip in ladder right angle structure, as another line of defence, sealing strip the thermal expansion strengthens piercing through of separation burning things which may cause a fire disaster to play better fire prevention, smoke protection effect.
Description
Technical field
The utility model relates to a kind of labeled door, specifically refers to a kind of new structure steel heat insulation fireproof door.
Background technology
Labeled door refers to the door that can meet fire stability, integrality and thermal insulation within a certain period of time and require.It is located between fire compartmentation, fire separation thing that emergency staircase, vertical shaft etc. have certain refractoriness.Labeled door is except the effect with common door, have more the effect stoping fire spreading and flue gas diffusion, spreading of the intensity of a fire can be stoped within a certain period of time, guarantee evacuating personnel, thus the important component part become in fire fighting equipment, be the important ring in society's fire prevention.
Labeled door divides by material fire-proof wooden door, fire resistance steel door, steel wood labeled door, other labeled doors etc.Fire resistance steel door refers to that main steel material makes doorframe, door leaf, the door with certain fire resistance of composition.If packing material in door leaf, then fill the fire-proof heat-insulating material harmless to human non-toxic, fire resistance steel door reaches fire resistance by door leaf steel material, but it is too simple for seaming meter between two door leafs, just extend a very thin lid patch in each outside one of the seam edge of two door leafs simply, be configured to class Z-type structure in middle seam place, it usually becomes the weak part of fire prevention of labeled door, finally have impact on obstruct burning things which may cause a fire disaster and the Smoke prevention effect of labeled door.
Utility model content
The purpose of this utility model is to provide a kind of new structure steel heat insulation fireproof door, to seaming meter proposition one new structure in door leaf, play strengthen intercepting burning things which may cause a fire disaster penetrating and better prevent fires, Smoke prevention effect.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of new structure steel heat insulation fireproof door, have two door leafs, the middle seam face of this two door leaf forms a ladder right-angle structure by suitable inside and outside right angle; The not homonymy side of this two door leaf is respectively provided with one for being closely placed on the lid seam plate stitched in two door leafs.
Described lid seam plate is formed primarily of zinc-plated cold-rolled steel sheet parcel PLASTIC LAMINATED.
The PLASTIC LAMINATED of described zinc-plated cold-rolled steel sheet parcel is double-layer structure.
The side facing with described door leaf of described lid seam plate is provided with the first fire-proof expansion seal strip.
Described first fire-proof expansion seal strip is provided be arranged side by side two of corresponding described two door leafs.
The middle straight edged surface place of described ladder right-angle structure is provided with the second fire-proof expansion seal strip.
After adopting such scheme, this Novel photo is for the beneficial effect of prior art:
One, the middle crack structure design of its two door leaf of labeled door adopt in the middle of the ladder right-angle structure of overlap joint, and lid seam plate is set in relative both sides, forms two hierarchic structure form, greatly strengthen and intercept penetrating of burning things which may cause a fire disaster, and fire prevention, Smoke prevention effect;
Two, lid seam plate preferably wraps up two-layer PLASTIC LAMINATED by zinc-plated cold-rolled steel sheet and forms, and it has higher heat-proof quality and greatly can reduce the penetration capacity of burning things which may cause a fire disaster, effectively prevents burning things which may cause a fire disaster from passing in door leaf and stitches, strengthen the fireproof performance of labeled door;
Three, the second fire-proof expansion seal strip can be set up further in ladder right-angle structure, even if when burning things which may cause a fire disaster passes the lid seam plate of side towards the fire, the fire-proof expansion seal strip set up now just can play a role, as another defence line, weather strip expanded by heating, strengthen intercepting penetrating of burning things which may cause a fire disaster, and play better fire prevention, Smoke prevention effect.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to a kind of new structure steel heat insulation fireproof door, as shown in Figure 1, forms primarily of doorframe 1 and two door leafs 2.
As Figure 2-3, the middle seam face of two door leafs 2 forms a ladder right-angle structure 20 by suitable interior right angle 201, outer right angle 202.Two door leafs 2 are respectively provided with (being welded with) lid seam plate 21, two door leaf 2 when cutting out on not homonymy side, and the lid seam plate 21 of both sides is closely placed on seam in two door leafs 2 from both sides respectively.
The ladder right-angle structure 20 of overlap joint in the middle of the middle crack structure design of its two door leaf 2 of this Novel fire-proof door adopts, and arrange lid seam plate 21 in relative both sides, is formed two hierarchic structure form with this, plays and strengthen intercepting penetrating of burning things which may cause a fire disaster, and fire prevention, Smoke prevention effect.
Preferably, lid seam plate 21 wraps up PLASTIC LAMINATED 212 primarily of zinc-plated cold-rolled steel sheet 211 and forms.The PLASTIC LAMINATED 212 that further zinc-plated cold-rolled steel sheet 211 wraps up is double-layer structure.This form of structure makes lid seam plate 21 have higher heat-proof quality, greatly can reduce the penetration capacity of burning things which may cause a fire disaster, effectively prevent burning things which may cause a fire disaster from passing in door leaf and stitch, strengthen the fireproof performance of labeled door.
Preferably, the side facing with door leaf 2 of lid seam plate 21 is provided with the first fire-proof expansion seal strip 213.This first fire-proof expansion seal strip 213 is provided with two further, and corresponding two door leafs about 2 are arranged side by side, to give full play to the sealing function of fire-proof expansion seal strip centering seam.
Preferably, the middle straight edged surface place of ladder right-angle structure 20 is also provided with the second fire-proof expansion seal strip 203.Even if when burning things which may cause a fire disaster passes the lid seam plate 21 of side towards the fire, the second fire-proof expansion seal strip 203 set up now just can play a role, as another defence line, weather strip expanded by heating, strengthens intercepting penetrating of burning things which may cause a fire disaster, and plays better fire prevention, Smoke prevention effect.
The foregoing is only the preferred embodiment that this is novel, all equalizations done with this novel right change and modify, and all should belong to the scope of this novel claim.
