Abstract

The utility model discloses a wooden thermal -insulated fire door that prevents of steel, including door frame, door leaf. It is articulated with the door leaf that the door frame passes through fire safety hinge. The door leaf is stood by as an outsider the centering in the thickness direction and is respectively that plywood, glass magnesium are dull and stereotyped, the expanded perlite PLASTIC LAMINATED. The plane size of expanded perlite PLASTIC LAMINATED is less than the dull and stereotyped plane size of plywood and glass magnesium. Be equipped with fire -retardant timber around the expanded perlite PLASTIC LAMINATED. The cross -section of four frames of door frame is L shape, and the door leaf plays the quilt in off position L shape door frame is spacing. The door frame with be provided with between the door leaf with L shape door frame matched with L shape fire prevention expandable sealing spare. Compared with the prior art, this is practical newly have intensity height, fire behavior good, effectively avoid the advantage that the door leaf warp.

Description

A kind of steel wooden heat-insulating fireproof door

Technical field

The utility model relates to a kind of labeled door field, particularly relates to a kind of steel wooden heat-insulating fireproof door.

Background technology

Carry out infrastructure construction (as subway, change and expand airport and stadium) on a large scale with country, architectural labeled door demand used is increasing, and performance requirement is more and more higher, and fireproof alert level requires more and more higher.

At present, densely populated place, at home, club adopt its coefficient of thermal conductivity of labeled door higher, during breaking out of fire just, easily cause door leaf temperature too high, thus cause door leaf to be easily out of shape, do not reach the requirement of fireproof performance; Conventional fire door intensity is poor in addition, and its impact resistance also has much room for improvement.

Utility model content

The utility model, for the deficiencies in the prior art, provides the steel that a kind of intensity is high, fireproof performance good, effectively avoid door leaf to be out of shape wooden heat-insulating fireproof door.

The utility model is solved the problems of the technologies described above by following technological means:

A kind of steel wooden heat-insulating fireproof door, comprises doorframe, door leaf, described doorframe by hinge for fireproof and described door leaf hinged; Described door leaf is respectively veneer, glass fibre and magnesium cement board, expanded perlite PLASTIC LAMINATED at thickness direction from export-oriented center; The planar dimension of described expanded perlite PLASTIC LAMINATED is less than the planar dimension of described veneer and glass fibre and magnesium cement board; The surrounding of described expanded perlite PLASTIC LAMINATED is provided with fire retarding wood; The cross section of four frames of described doorframe is L shape, described door leaf in off position under spacing by described L-shaped door frame; The L shape fireproof expansion seal part matched with L-shaped door frame is provided with between described doorframe with described door leaf; Described doorframe is the doorframe that cold-rolling galvanization steel plate is made.

Preferably, described L shape fireproof expansion seal part is arranged on described doorframe embeddedly.

Preferably, the cross section of described fire retarding wood is rectangle.

Preferably, described door leaf offers window, described window is equipped with flame resistant glass.

Preferably, the height of described door leaf is (1.9-2.5) m, and width is (0.8-1.2) m, and thickness is (0.08-0.12) m.

Preferably, described door leaf is also provided with Fire-proof lock.

Preferably, described hinge for fireproof is 3.

The utility model has the advantage of:

By arranging expanded perlite PLASTIC LAMINATED in the inside of door leaf, improving flameproof effect, arranging while glass fibre and magnesium cement board improves flameproof effect further, improving the intensity of door leaf and shock-resistant ability.By installing L shape fireproof expansion seal part on doorframe embeddedly, improving sealing flameproof effect and the noise produced when door leaf cuts out and between steel door frame can be reduced.Owing to employing a circle fire retarding wood in the surrounding of expanded perlite PLASTIC LAMINATED, the use amount of expanded perlite PLASTIC LAMINATED can be reduced, namely alleviate the deadweight of door leaf, make door leaf have lighter deadweight while reaching effective heat-insulating, fire-preventing.

The reasonable setting of 3 hinge for fireproofs, can effectively control door leaf sedimentation.

Its fire insulation >=2 hour of steel wooden heat-insulating fireproof door of the present utility model, fire integrity >=2 hour; Can bear 30kg sandbag 9 Secondary Shocks, after impact, door lock, hinge do not come off, and door leaf surface remnants return distortion≤10mm.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of steel wooden heat-insulating fireproof door of the utility model;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the B-B sectional view of Fig. 1.

Specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

As Figure 1-3, the present embodiment discloses a kind of steel wooden heat-insulating fireproof door, comprises doorframe 1, door leaf 2, and doorframe 1 is hinged by hinge for fireproof 3 and door leaf 2; Doorframe 1 is cold-rolling galvanization steel plate, and the cross section of its four frames is L shape, door leaf 2 in off position under spacing by L-shaped door frame 2.Door leaf 2 thickness direction from outer in be disposed with veneer 21, glass fibre and magnesium cement board 22, expanded perlite PLASTIC LAMINATED 23.The planar dimension of expanded perlite PLASTIC LAMINATED 23 is less than the planar dimension of described veneer 21 and glass fibre and magnesium cement board 22.The surrounding of expanded perlite PLASTIC LAMINATED 23 is provided with fire retarding wood 24.L shape fireproof expansion seal part 4 is provided with between doorframe 1 and door leaf 2, L shape fireproof expansion seal part 4 is arranged on the doorframe 1 that cross section is L shape, under the cooperation of the two, between door leaf 2 and doorframe 1, sealing effectiveness is good, and directly contacts with doorframe 1 when avoiding door leaf 2 to close and produce harsh noise.

The cross section of the fire retarding wood 24 that the utility model provides is cuboid.Certainly, also can be the cross section of other shapes, as long as the side that expanded perlite PLASTIC LAMINATED 23 contacts with fire retarding wood 24 arranges the structure form matched with it.

Conveniently watch situation outdoors, window 25 can be offered on door leaf 2, window 25 is equipped with flame resistant glass.

The door leaf 2 that the utility model provides is rectangle tabular, and its height is (1.9-2.5) m, and width is (0.8-1.2) m, and thickness is (0.08-0.12) m.Certainly, according to different user's requests, the shape and size of door leaf 2 are not limited to this.

Labeled door be unable to do without Fire-proof lock 5, the lockhole that Fire-proof lock 5 can effectively shutoff door leaf 2 be offered.

Use material feature due to steel fire-proof wooden door, cause door leaf 2 to be conducted oneself with dignity heavier, in open and close process repeatedly, easily produce sedimentation, cause door leaf 2 to be out of shape.Door leaf 2 sedimentation or distortion can be controlled by setting up hinge.The utility model provides 3 hinge for fireproofs 3, and wherein two hinges 3 are contained in the top of door leaf 2 and doorframe 1, and one is contained in bottom.

Its fire insulation >=2 hour of steel heat insulation fireproof door of the present utility model, fire integrity >=2 hour; Can bear 30kg sandbag 9 Secondary Shocks, after impact, door lock, hinge do not come off, and door leaf surface remnants return distortion≤10mm.

The foregoing is only the preferred embodiment that the utility model is created; do not create in order to limit the utility model; the any amendment done within all spirit of creating at the utility model and principle, equivalent to replace and improvement etc., all should be included within protection domain that the utility model creates.
