Abstract

The utility model discloses a door with three functions, which relates to a fireproof and burglarproof door. The utility model aims to solve the problems that the prior fireproof door or burglarproofdoor only has the function of fire resistance or burglary prevention and can not give consideration to both, and further has no winter proofing and environmental protecting functions. The door with three functions comprises a main door leaf, a door frame, at least two first fireproof hinges, a fireproof and burglarproof lock, a first perlite plate and a first paint layer, wherein the main door leaf adopts a casing provided with a cavity and made of a cold-rolling galvanized steel plate or woods, the side surface of the main door leaf near the door frame is in rotational connection with the door frame through the first fireproof hinges, a fireproof and burglarproof lock is mounted on the other side end face near the main door leaf, the first perlite plate is mounted in the cavity of the main door leaf, and the first paint layer is coated on the outer surface of the main door leaf. Due to the arrangement of the pearlite plate inside the cavity of the door leaf, the door leaf has heat-insulated effect. Therefore, the utility model not only has the functions of fire resistance and burglary protection, but also has the function of winter protection; and a rust preventing paint layer iscoated on the outer surface of the main door, so that the door is more environment-friendly than the parkerized door leaf.

Description

The environment-friendly type three protective door

Technical field

The utility model relates to a kind of fire prevention, security door.

Background technology

Existing labeled door or security door mostly are steel casing, and middle filling fire resisting material is made, and it has played fire prevention or antitheft effect, can not the two take into account, and not winter protection; For preventing to get rusty, metal shell also needs phosphatization to handle, and phosphatization is handled and can be produced a large amount of production waste drainages, therefore is unfavorable for environmental protection.And the refractory material burning time contains poisonous, harmful material.

The utility model content

The purpose of this utility model is for solving that existing labeled door or security door can only be prevented fires separately or antitheft, can not the two take into account, and the problem of not winter protection and not environmental protection, and a kind of environment-friendly type three protective door is provided.

The utility model comprises main door leaf, doorframe, at least two the first fire prevention hinges, fire-proof and theft-proof lock, first pearlite slab and first enamelled coatings, main door leaf is by cold-rolling galvanization steel plate or the wooden housing with cavity of making, main door leaf is rotationally connected by at least two first fire prevention hinges and doorframe near the side of doorframe, main door leaf is equipped with the fire-proof and theft-proof lock near the opposite side end, first pearlite slab is housed in the cavity of main door leaf, and the external surface of main door leaf scribbles first enamelled coating.

The utility model has the advantages that: because the utility model has been adorned pearlite slab in the inner chamber of door leaf, make door leaf have heat insulation effect, therefore, the utility model is fire-proof and theft-proof not only, also has the function of winter protection sound insulation; The external surface of main door scribbles rust preventive coating, than through the more environmental protection of parkerized door leaf.
