Because door leaf second floor backplate constitutes through clamping on door leaf first layer backplate constitutes with draw -in groove matched with checkpost, so when door leaf second floor backplate constitution took place to warp, door leaf second floor backplate constitutes the accessible checkpost and the draw -in groove takes place the displacement on door leaf first layer backplate constitutes, turns into displacement with the deformation to furtherly has reduced the deflection. Be applicable to the door.
Description
Technical field
The utility model relates to labeled door field, particularly relates to a kind of three-ply plate steel heat insulation fireproof door fan.
Background technology
Before the utility model proposes, the steel heat insulation fireproof door that circulates in market fan is mostly surface backplate two-layered steel plates structure altogether, this fire-proof door leaf surface backplate rigid connection and inner stuffing is heat-insulating fire-proofing material.
This steel heat insulation fireproof door fan is in National Fire door detection experiment, because the temperature of the counter-fire face steel plate of door leaf is much larger than the back of the body fiery face steel plate, so counter-fire face steel plate hot deflection is also much larger than the back of the body fiery face steel plate, therefore counter-fire face steel plate differs larger with the deflection of the back of the body fiery face steel plate, like this, door leaf will inevitably produce Bending Deformation; Simultaneously, because door leaf hinge limit has multiple hinge to fix, so the flexural deformation on door leaf hinge limit is less, still can meet the standard every cigarette fire insulation, but because door leaf lockset limit only only has lockset fixed point, so the free bend distortion because not having fixed point of the top and the bottom branch on door leaf lockset limit, therefore, the deflection on door leaf lockset limit is very large, and door leaf finally will be caused to lose every cigarette fire insulation ability.
Meanwhile, the excessive integrality also destroying heat-insulating fire-proofing plate of door leaf distortion, thus cause the thermal insulation of door leaf to lose efficacy.
Utility model content
The purpose of this utility model is the deficiency in order to overcome above-mentioned background technology, provide a kind of door not easily temperature distortion three-ply plate steel heat insulation fireproof door fan.
In order to realize above object, a kind of three-ply plate steel heat insulation fireproof door fan that the utility model provides, comprise door skin, the door leaf first floor backboard forming the first cavity with described door skin is formed, be filled in the first floor fire prevention filler in described first cavity, the plate face that described door leaf first floor backboard is formed is provided with several draw-in grooves, described door leaf also comprises door leaf second layer backboard and forms, described door leaf second layer backboard forms and is installed on described door leaf first floor backboard forms by the clamp matched with described draw-in groove, described door leaf first floor backboard forms in the second cavity of forming with described door leaf second layer backboard and being formed and is filled with second layer fire prevention filler.Add one deck backboard again by the back side formed at door leaf first floor backboard, and fire proofing material is filled in space between two-layer backboard, like this, three-ply plate structure can Reducing distortion effectively; Simultaneously, be installed on door leaf first floor backboard forms because door leaf second layer backboard is formed by the clamp matched with draw-in groove, so when door leaf second layer backboard formation deforms, door leaf second layer backboard forms and is subjected to displacement on door leaf first floor backboard is formed by the clamp that cooperatively interacts and draw-in groove, distortion is converted into change in displacement, thus further reduces deflection.
In such scheme, described draw-in groove is the elongated hole vertically arranged, described clamp is the clamp matched with described elongated hole, described clamp is vertically arranged on described door leaf second layer backboard and forms towards on the panel of described door leaf first floor backboard formation, and the junction that described clamp and described door leaf first floor backboard are formed is provided with card interface.
In such scheme, the length of described elongated hole is greater than the length of described clamp.
In such scheme, it is shaping that described clamp forms flange by described door leaf second layer backboard, and described clamp and described door leaf second layer backboard are configured to overall structure.Form the shaping clamp of flange by door leaf second layer backboard, can one-shot forming be realized, thus decrease operation, improve working (machining) efficiency.
In such scheme, the flange place that described door leaf second layer backboard is formed and described door leaf first floor backboard form and form groove, are provided with fire-proof heat insulation board in described groove.The fire-proof heat insulation board added can further Reducing distortion amount.
The beneficial effect that the technical scheme that the utility model provides is brought is:
1, the back side by forming at door leaf first floor backboard adds one deck backboard again, and fire proofing material is filled in space between two-layer backboard, and like this, three-ply plate structure can Reducing distortion effectively;
2, be installed on door leaf first floor backboard forms because door leaf second layer backboard is formed by the clamp matched with draw-in groove, so when door leaf second layer backboard formation deforms, door leaf second layer backboard forms and is subjected to displacement on door leaf first floor backboard is formed by the clamp that cooperatively interacts and draw-in groove, distortion is converted into change in displacement, thus further reduces deflection;
3, form the shaping clamp of flange by door leaf second layer backboard, can one-shot forming be realized, thus decrease operation, improve working (machining) efficiency;
4, the fire-proof heat insulation board added has good thermal insulation, also can block or delay heat to a certain extent and propagate to door skin, thus can further Reducing distortion amount.
The utility model is compared with the prior art, and fully its superiority of display is: heat-insulating, fire-preventing is effective, structure is simple and cost is low etc.
