Abstract

The utility model provides a novel fire-retardant theft-proof door, which comprises a door leaf and a door frame, wherein the door leaf comprises a big door leaf and a small door leaf, and the corresponding closing edges of the big and the small door leaves are shaped like matched staggered concavo-convex rabbets, in which fire-retardant expandable seal strips are arranged; the upper and the lower borders of the door frame are provided with anti-prizing hooks; and the big and the small door leaves are made of covered steel plates, between which fire-retardant heat-insulating material is filled. Fire-retardant blind hinges are arranged between the left and the right borders of the door frame and the door leaf, and are mounted on the door leaf; the sides of the left and the right borders, which are close to the door leaf, are provided with grooves, in which fire-retardant expandable seal strips are stuck; inner border laces and outer border laces are mounted on the upper border and the left and the right borders, and fire-retardant heat-insulating material is filled between the inner laces and the outer laces; and the upper border and the left and the right borders are provided with partitioning grooves. The utility model has the advantage of good fire-retardant and theft-proof effects.

Description

Novel fireproof and theftproof door

Technical field

The utility model relates to the door that a kind of fire-proof and theft-proof is stolen.

Background technology

Labeled door is to play fire prevention, Smoke prevention, heat insulation, the key facility that cuts off the heat transfer function, can effectively stop fire spread and Flue Gas Diffusion, strives for the time that fire-fighting is put out the fire, to ensureing that people's lives and properties play an important role.According to increasingly serious fire-fighting situation, new labeled door standard has been implemented in country's issue.At the fire resistance requirement among the new GB 129955-2008, the heat-insulating fireproof door fire resistance period was 1.5 hours, until 3 hours.Compare traditional labeled door, fire-proof function is fragile relatively or do not reach the fire-proof and thermal-insulation effect, and anti-theft feature does not embody.Smolder easily string fire of traditional labeled door crack between a door and its frame place, and do not have intensity, make the door leaf distortion easily.If in fire, go here and there fire easily and smolder at centre joint place, can't reach the requirement of new labeled door standard and the purpose that assures the safety for life and property of the people.Have, the doorframe of traditional labeled door is an individual layer again, in fire process, is difficult to play the effect of fire-proof and thermal-insulation.

Summary of the invention

For separating the problem that aforementioned labeled door exists, the utility model provides a kind of novel fireproof and theftproof door, comprises door leaf and doorframe, and door leaf is made up of big door leaf and wicket fan, perhaps, only is made of single door and doorframe; When having big or small door leaf, the closed sides of large and small door leaf correspondence is staggered concavo-convex matched shape, in the staggered concavo-convex groove, is pasted with the fire prevention expanding sealing strips, and simple gate fan or large and small door leaf are covered by steel plate and form, and the centre is filled with fire-proof heat-insulating material.

Between the left and right doorframe of described doorframe and the door leaf fire prevention blind hinge is arranged, the fire prevention blind hinge is installed on the door leaf.

The upper door frame of described doorframe and lower door frame have pick-proof to collude.

Described doorframe and door leaf side contact position are fluted, post the fire prevention expanding sealing strips at groove.

Lace structure outside the lace and doorframe is installed on upper door frame and left and right doorframe in the doorframe, between inside and outside lace, is filled with fire-proof heat-insulating material.

On described upper door frame and the left and right doorframe, have partition grooves.

The utility model has the advantages that, because the seam crossing of two door leafs is concavo-convex couplings, play the pick-proof effect on the one hand, concavo-convex in addition safety groove has increased the cross-sectional length of doorframe, cause to prolong the doorframe heat transfer, this doorframe has double-deck lace structure, fills a kind of fire-proof and thermal-insulation environment-friendly materials in the middle of two laces, even heat has passed on the interior lace, the fire-proof and thermal-insulation environment-friendly materials play an anti-fire action here.The utility model plays anti-theft feature under the situation of not destroying Fireproof door structure, be particularly suitable for labeled door and house lead in security door that current high building project is used.
