Description

A kind of fire resistance steel door

Technical field

This utility model relates to a kind of fire resistance steel door, belongs to fire resistant doorsets technical field.

Background technology

Fire resistant doorsets are mainly used in fire district cuts off and need the building of fireproof partition, when fire occurs Can reliably close, intercept the spreading of smog and flame, expand.

In concrete engineering practice, conventional fire door can meet the requirement of general engineering project. But in the special engineering such as nuclear power, military project field, some functional area usually needs transnormal fire prevention Demand, and conventional fire door cannot meet this current demand.Prior art is for the fire prevention of fire resistant doorsets The thickness generally by thickening pearlite slab that promotes of effect realizes, but increase perlite simply The thickness of plate not only greatly improves weight and the cost of fire resistant doorsets, and fireproof effect promoting is the most not Fairly obvious, how to be designed by the structure optimized, promote the flameproof effect of fire resistant doorsets, become This area needs the technical barrier of solution badly.

Utility model content

This utility model technical issues that need to address are: prior art is for the flameproof effect of fire resistant doorsets The thickness generally by thickening pearlite slab that promotes realize, but simply increase pearlite slab Thickness not only greatly improves weight and the cost of fire resistant doorsets, and fireproof effect promoting is the most very Substantially.This utility model is intended to the structure by optimizing and designs, and promotes the flameproof effect of fire resistant doorsets.

This utility model takes techniques below scheme:

A kind of fire resistance steel door, it is characterised in that: include doorframe 1, door leaf 2, hinge 5, lockset 3； The cross section of described doorframe 1 has hierarchic structure, and door leaf 2 has corresponding hierarchic structure；Described Surrounding position within door leaf 2 is provided with bar keel 7, bar keel 7 be respectively provided on two sides with one layer prevent Fire plate 9；The outside bonded metal composite plate 10 of described PLASTIC LAMINATED 9；Composite metal plate 10 and rectangle dragon Separated by PLASTIC LAMINATED 9 between bone 7, cut off the heat conduction path of metalwork；A pair PLASTIC LAMINATED 9 and square Filling pearlite slab 8 in the space that shape Os Draconis 7 surround, described door leaf 2 is by hinge 5 with doorframe 1 even Connecing, described hinge 5 is external installing type, and is fixed with door leaf 2 by bolt, thus does not destroy door Structure outside Shan.

Further, described fire resistance steel door is double door, and two door leaf 2 lap-joints are step-like joining The structure closed, and lid seam plate 11 is set at the outer surface of lap-joint.

Further, described hinge 5 is fixed on front side of door leaf 2.

Further, described door leaf 2 fixedly mounts world push-rod lock 4 and anti-theft pin 6.

Further, two door leafs 2 are respectively arranged fix a world push-rod lock 4.

The beneficial effects of the utility model are:

1. bar keel is respectively provided on two sides with one piece of PLASTIC LAMINATED, and the outside of PLASTIC LAMINATED is provided with composite metal plate. Composite metal plate is bonded on PLASTIC LAMINATED, does not contacts UNICOM with Os Draconis, has cut off the conduction of heat of metalwork Approach, makes not produce inside and outside door leaf heat bridge effect, well ensure that the overall flameproof effect of fire resistant doorsets.

2. the world push-rod lock structure durable, easy to use of configuration on fire resistant doorsets, beneficially evacuating personnel, The personal safety of energy well support personnel when there is the condition of a fire.

3. fire resistant doorsets itself have good heat resistanceheat resistant deformation and capacity of heat transmission, it is possible to by domestic, state Two kinds of border fire resistance test method testing, reaches integrity and the thermal insulation requirement of 3 hours.

4., when fire resistance steel door is double door, Liang Ge door leaf lap-joint is the structure of step-like cooperation, and Outer surface in lap-joint arranges lid seam plate, further ensure that the effect of fire-proof and thermal-insulation.

5. hinge described in is external installing type, and is fixed with door leaf by bolt, and this mounting means is not Destroy door leaf partial structurtes, it is ensured that door leaf entirety fire-proof and thermal-insulation structure complete.
