Abstract

The utility model discloses a fire retarding door, comprising a door case and a door leaf, is characterized in that the door leaf comprising two splints, an inner skeleton and an inner fireproof which is shaped by the filling expansion pearlite between the two splints is arranged on the door case, and a fireproofing board is positioned between the door case and the inner skeleton, as well as between the inner skeleton and the splint, and the expansion pearlite in the inner fireproof is made by stirring inorganic fireproof materials mixed with pearlite, magnesium chloride and sodium chloride and the mucilage of the magnesium chloride. The model formed with one-time molding simple structure has the advantage of a high integral mechanical intensity, a high refractory limit and heat insulating effect that is in accordance with the national fireproof standards.

Description

A kind of labeled door

Technical field

This practicality newly relates to a kind of labeled door, and particularly a kind of once molding formed labeled door with expanded perlite belongs to door-window kind in the building.

Background technology

Door is the member that generally adopts in all kinds of buildings, in case in the building space because of accidental cause on fire after, generally use at present the weakness of all kinds of doors in building also fully to expose, as filling alumina silicate in the more fireproof door frame of usefulness, during burning, along with two-layer wood falls, alumina silicate also falls thereupon, and flameproof effect is poor.Existing pearlite slab is when being processed into labeled door, pearlite slab and inner frame make two bites at a cherry, the slit is big between plate and the framework, when test, can produce and wear fiery phenomenon, can not reach fire-protection standard, place Fireproof door structure that two PLASTIC LAMINATED make except not reaching the fire-protection standard with the pearlite slab both sides, its whole deal is heavy, door leaf open number of times too much the back hinge obscission can take place.

Summary of the invention

The purpose of this utility model is for the improvement to existing labeled door, and a kind of once molding formed labeled door with expanded perlite is provided.

The technical solution of the utility model is: a kind of labeled door is made up of doorframe, door leaf, be characterized in, door leaf comprises clamping plate, inner frame and fire prevention inner bag, door leaf directly is assembled on the doorframe, be lined with PLASTIC LAMINATED between doorframe and the inner frame and between clamping plate and the inner frame, described fire prevention inner bag constitutes by filling expanded perlite between the two clamping plates.

Described expanded perlite is to be mixed together by inorganic fireproof material and magnesium chloride solution glue that perlite, magnesium chloride and sodium chloride mix.

The utility model is because with expanded perlite once molding formed structure, and is therefore simple in structure and overall mechanical strength is high, and fire endurance, effect of heat insulation height conform to the fire-protection standard of national regulation.

Description of drawings

Fig. 1 is the Fireproof door structure front view;

Fig. 2 is the A-A sectional drawing of Fig. 1.

The specific embodiment

By Fig. 1, shown in Figure 2, a kind of labeled door is made up of doorframe 1, door leaf 2, be characterized in, door leaf 2 comprises clamping plate 3, inner frame 4 and fire prevention inner bag 5, door leaf 2 directly is assembled on the doorframe 1, be lined with PLASTIC LAMINATED 6 between doorframe 1 and the inner frame 4 and between clamping plate 3 and the inner frame 4, described fire prevention inner bag constitutes by filling expanded perlite 7 between the two clamping plates 3.

Described expanded perlite is to be mixed together by inorganic fireproof material and magnesium chloride solution glue that perlite, magnesium chloride and sodium chloride mix.The described door leaf 2 of clamping plate 3, inner frame 4 and fire prevention inner bag 5 that comprises forms by the hot press one-step mould, and product processes is simple, and production link reduces, and has adopted the hot pressing once-forming, and inner frame can adopt China fir to replace Liu Anmu, has reduced cost of material.Perlite fire prevention inner bag and inner frame are once finished processing, and be seamless between fire prevention inner bag and the inner frame, and fire prevention and soundproof effect are good.

By shown in Figure 1, be equipped with fire-proof glass window 8 on the door leaf 2, door leaf 2 directly is assembled on the doorframe 1 by fire prevention hinge 9.
