Abstract

The utility model relates to an element of a door which can isolate fire hazards, and particularly relates to a door leaf. The wooden fireproof door leaf of the utility model is composed of a skeleton 1, a panel 6, a backboard 9, fireproof boards 3 and flame resistant materials 4. The skeleton is a three-dimensional frame of which the periphery is provided with a lug boss. The skeleton is provided with a plurality of tendons 10 in the height direction and in the width direction. The number of the fireproof boards is two, and are respectively positioned at the concave parts of the width and the height planes of the lug boss, and are fixedly connected with the skeleton and the tendons. The flame resistant materials are positioned in the gap between the two fireproof boards. The panel and the back board are respectively positioned outside in the width direction of the skeleton, and are fixedly connected with the skeleton and the fireproof boards. Due to the adoption of a reasonable structure, the utility model can adopt cheap raw materials, and products qualified and high-quality products. The utility model lowers the production cost of wooden fireproof doors, satisfies low-value fire protection product markets at present, can effectively isolate fire hazards when fire hazards occur, and can satisfy the national standard GB12955-91< < wooden fireproof door general technical specifications > >.

Description

The fire-proof wooden door fan

Technical field

The utility model relate to a kind of isolate fire the door in parts, especially door leaf.

Technical background

Chinese patent application numbers 93223032.6 discloses a kind of " fire-proof wooden door ", and its technical scheme comprises that it is formed by connecting through hinge by doorframe, door leaf.Its main feature is: the foaming heat insulation plate of anti-flaming thermal-insulation is housed on the counter-fire face of wooden doorframe, wooden door leaf, fire-retardant, heat insulation foaming sealing mat is housed on doorframe.Wooden doorframe, door leaf are all through the fire retardant immersion treatment.After fire took place, the foaming heat insulation plate of counter-fire face and foaming sealing mat thickness rapidly increased to 10 times of original thickness, thereby can seal penetrating of prevention flame effectively, realize fire prevention.Chinese patent application numbers 99216848.1 discloses a kind of " Fireproof door structure ", comprises: a pair of refractory slab suitable distance of being separated by; The pair of metal net is located at the refractory slab inboard; One framework is made up of some first, second skeletons that are longitudinal extension or horizontal expansion, and between two wire laths; Some insulating assemblies are located at framework inside, its both sides respectively with each refractory slab suitable distance of being separated by, have at least two insulating boards of the suitable distance of being separated by on it, and be convexly set in the some heat insulating strips on the outer rim; By this so that between adjacent each refractory slab and insulating board, between each insulating board, all can form a tabular compartment that prevents the rapid radiation of heat energy.

At present build a building, widely-used fire resistance steel door such as factory building, public place, because the harmful competition in market, the price of fire-proof wooden door is pressed onto can not produces effective fireproof fire resistance steel door, add the incompatibility of traditional processing technology, make the market of labeled door almost not have qualified fire resistance steel door, make the people's lives and property be subjected to serious prestige association.

Summary of the invention

The purpose of this utility model is to overcome the prior art deficiency, a kind of low price is provided and can effectively isolates fire, prevents the fire-proof wooden door fan that fire takes place.

Fire-proof wooden door fan described in the utility model is made up of skeleton, panel, backboard, PLASTIC LAMINATED and fire proofing, described skeleton is the space framework that boss is arranged around, on the height of skeleton and width, some muscle are set, PLASTIC LAMINATED is two, lay respectively at the recessed portion of boss width and elevation plane, fixedly connected with muscle with skeleton, in the space of fire proofing between two PLASTIC LAMINATED, panel and backboard lay respectively at the skeleton width outside, and fixedly connected with PLASTIC LAMINATED with skeleton.

Described skeleton, panel, backboard are not firebrand material; PLASTIC LAMINATED is fixedlyed connected with the nail that is connected to of skeleton and muscle; Be connected to feather joint between skeleton and the muscle; Panel and backboard and skeleton and PLASTIC LAMINATED be connected to bonding, or bonding adds wooden peg and connects.

The utility model makes and can adopt cheap raw material owing to adopted rational structure, produces qualified, high-quality product.The utility model has reduced the cost of production of fire-proof wooden door, satisfies the fire product market of present low value, can isolate fire effectively when fire takes place, and can satisfy standard GB 12955-91 " fire-proof wooden door general technical specifications ".

Description of drawings

Fig. 1 is that door leaf described in the utility model is installed in the top plan view on the doorframe.

Fig. 2 is a skeleton front view described in the utility model.

Among the figure: 1-skeleton, 2-nail, 3-PLASTIC LAMINATED, 4-fire proofing, the 5-glue of preventing fires, 6-panel, 7-doorframe, 8-fireproofing glue strip, 9-backboard, 10-muscle.

The specific embodiment

Below in conjunction with accompanying drawing the utility model being described further, is embodiment of the present utility model, and embodiment only is used to describe in detail the utility model, and does not limit it.

The described skeleton 1 of present embodiment adopts not firebrand material to make, some muscle 10 are set on skeleton 1, form net structure, be connected to feather joint between skeleton 1 and the muscle 10, described skeleton 1 is the space framework that boss is arranged around, PLASTIC LAMINATED 3 is two, lay respectively at the recessed portion of boss width and elevation plane, after loading onto PLASTIC LAMINATED 3, form a plane with boss, in the space of fire proofing 4 between two PLASTIC LAMINATED 3, panel 6 and backboard 9 lay respectively at the PLASTIC LAMINATED 3 and skeleton 1 outside, with PLASTIC LAMINATED 3 and skeleton 1 bonding.

Present embodiment is pressed in door skin 6, backboard 9 usefulness press on the skeleton 1 with it, and is bonding with fire prevention glue 5, and fire prevention glue 5 also has one deck fire-proof curtain, makes it indeformable, more firmly attractive in appearance and reduce cost.The described PLASTIC LAMINATED of present embodiment 3 adopt have glow, heat insulation various sheet materials, because of being installed in door skin 6, the backboard 9, it is not attractive in appearance for demand.PLASTIC LAMINATED 3 usefulness nails 2 are fixed on the skeleton 1, and it is all bonding with fire prevention glue 5 (water glass " silicate of soda ") and panel 6, backboard 9, even its intensity is not high, but the globality and the intensity of door leaf have also been increased, so can adopt cheap PLASTIC LAMINATED to greatly reduce cost.Fireproofing glue strip 8 on the doorframe 7 adopts the right angle and is embedded in the groove of doorframe, has dual fire-proof function.

The fire prevention glue (water glass " silicate of soda ") that present embodiment uses, its adhesive strength is not fine, but because this bonding door face board, backboard and skeleton large tracts of land bonding, do not need the price very good foamed glue of high adhesiveness energy and other bonding agent at high price, and water glass itself is exactly a kind of good fire prevention, fire material, and cheap.

Present embodiment has panel 6, fire prevention glue 5 (water glass " silicate of soda "), PLASTIC LAMINATED 3, fire proofing 4 (alumina silicate fibre or rock silk floss), PLASTIC LAMINATED 3, fire prevention glue 5 (water glass " silicate of soda "), backboard 9 seven road barriers to improve the performance of fire prevention fire insulation greatly when fire takes place.
