Description

A kind of steel heat insulation fireproof door

Technical field

The utility model relates to a kind of steel heat insulation fireproof door, belongs to labeled door technical field.

Background technology

Labeled door cuts off and needs in the building of fireproof partition for fire district, when fire occurs, reliably closes, and for intercepting spreading, expanding of smog and flame, therefore the intensity of fireproof door and heat-insulating capability must meet the requirement of national labeled door standard.The fire resistance period of first class labeled door must reach 1.5 hours.It is 1000 DEG C that labeled door door leaf in combustion testing stove is subject to fiery surface temperature, and after 1.5 o'clock, door leaf unexposed surface temperature is no more than 180 DEG C.Require indeformable, without leap up fire, the phenomenon of smoldering.

The structure of the fire resistance steel door of prior art comprises keel from inside to outside, PLASTIC LAMINATED, metal sheet, PLASTIC LAMINATED is gluing to be connected on keel, metal sheet again glue in PLASTIC LAMINATED, because glue is often due to the bonding phenomenon of planeness reason appearance point, so firmly degree is inadequate, the inertial thinking that prior art increases the method for Fireproof door structure intensity and fire-protection rating is the thickness of thickening PLASTIC LAMINATED, causes the thickness of first class labeled door very thick, and materials cost is higher, flameproof effect is also not as people's will.

Also have in order to prevent the PLASTIC LAMINATED distortion fire of leaping up, alter cigarette, more compound one deck heat insulation layer, also have and adopt adiabatic bridge structure, its shortcoming is with a lot of thermal insulation gap bridge parts, and be mutually a contact surface, local pressure, intensity is low, complex process, efficiency is low, and cost is high, and yield rate and uniformity are poor.

Summary of the invention

The utility model technical issues that need to address are, existing steel heat-insulating fireproof door, flameproof effect is not good, easily produce the phenomenon that leaps up fire, smolders, in order to improve the fire-protection rating of labeled door, the inertial thinking of prior art is the thickness that increases PLASTIC LAMINATED, but the effect of improving is still not good, and causes materials cost significantly to rise.The bridge structure of the employing thermal insulation also having, and be mutually a contact surface, local pressure, intensity is low, complex process, efficiency is low, and cost is high, and yield rate and uniformity are poor.

The utility model is taked following technical scheme:

A kind of steel heat insulation fireproof door, comprise PLASTIC LAMINATED, Door leaf frame, keel, described Door leaf frame is welded into entirety with the keel of arranging in length and breadth, the cross section of described keel is hollow rectangle or Contraband font, the both sides of keel are respectively equipped with a PLASTIC LAMINATED 10, the plane laminating of PLASTIC LAMINATED 10 and keel, and PLASTIC LAMINATED 10 is fixed on keel with sunk screw 9; The outside of described PLASTIC LAMINATED 10 fit bonding fireproof decoration plate or steel plate.

Because the size major part of prior art labeled door is below 2100mm*2300mm, the general this method of monoblock PLASTIC LAMINATED outsourcing steel door sheet that adopts, be only suitable for small size door, and impact resistance power is very little, or in Door leaf frame, adding keel and gain in strength, is all gluing but its shortcoming is total, and keel and PLASTIC LAMINATED contact surface are little, can not form firmly entirety, easily peel off mutually, be out of shape.Also have and adopt adiabatic bridge structure, its shortcoming is with a lot of thermal insulation gap bridge parts, and is mutually a contact surface, local pressure, and intensity is low, complex process, efficiency is low, and cost is high, and yield rate and uniformity are poor.

For being difficult to reach the fire-resistant requirement of 1.5 hours as the large-sized double door of 3100mm*3100mm or the above technology of larger sized door and method.

The technical program enters keel after two PLASTIC LAMINATED are penetrated to PLASTIC LAMINATED at a certain distance with countersunk self-tapping screw, is fastened on respectively on keel tow sides, forms keel and is clamped at middle tight structure.Two metal sheets or fireproof decoration plate door leaf sheet respectively gluing, on positive and negative two fast PLASTIC LAMINATED faces, contacts UNICOM with keel, have cut off the heat conduction via of metalwork, and in fact whole door leaf has become a large thermal insulation gap bridge.

Further, the cross section of described Door leaf frame is convex shape.

Further, the centre of described steel heat insulation fireproof door is provided with form 5, after its flame resistant glass bending frameworks, is welded into entirety with keel.

Further, the centre of two PLASTIC LAMINATED 10 is provided with fire prevention filler.

Further, described fire prevention filler is perlite fireproof plate.

Further, described steel heat insulation fireproof door disposes fire prevention Expansion sealing body.

Further, described steel heat insulation fireproof door is double door labeled door, and its appearance and size is 3100mm*3100mm.

The utility model has overcome state of the art and has occurred from difficulty from complicated inertial thinking and technology prejudice in research and development manufacturing process, has ignored simple and effective technology and technique.

The utility model has reached high temperature small deformation and insulating refractory requirement with rational topology layout and simple technique.Be applicable to batch production, reduce waster, ensured the uniformity of product.Production efficiency is high, at the bottom of cost, the utlity model has obvious economic benefit.

The beneficial effects of the utility model are:

1) rational deployment of door leaf steel work, Door leaf frame and the entirety that is welded into of arranging in length and breadth keel.

2) in the middle of, after the equal bending of form flame resistant glass framework, be welded, and be welded into entirety with keel, Stability Analysis of Structures.

3) PLASTIC LAMINATED is fastening at a certain distance with sunk screw and door leaf keel, and front and back two sheet metal door sheets cling with PLASTIC LAMINATED again.The combination technology of this uniqueness has been blocked heat conduction path, and accomplished not peel off, not yielding, the fire of not leaping up smolders.

4) dispose fire prevention Expansion sealing body, fire proof seal better effects if.

5) the utility model labeled door meets mechanical deformation principle, has good ability of anti-deformation, has ensured that door reaches the requirement of refractory heat-insulating GB in less thickness.

6) the utility model labeled door has been because having replaced the heat insulation gap bridge parts of complicated multiple spot, therefore can be easily differs and needs the heat-insulating, fire-preventing of insulation wall and similar device for single fan labeled door and all size.
