Thermal insulation and fireproof door and manufacturing method thereof

Abstract

The invention provides a thermal insulation and fireproof door and a manufacturing method thereof. According to the thermal insulation and fireproof door, the technical problem that an existing technology is poor in fireproof effect and the like is solved. The thermal insulation and fireproof door comprises a door frame with a fireproof function and at least one door leaf. The door leaves are rotationally arranged on the two opposite inner sides of the door frame correspondingly. The door frame comprises a door frame cover plate made of a metal material. A basal body frame made of a fireproof material is arranged in the door frame cover plate. Each door leaf comprises a door leaf skeleton made of a fireproof material and / or a metal material. The door leaf skeletons are filled with thermal isolation door cores made of thermal isolation materials. At least one layer of door leaf inner plates made of fireproof materials is arranged on the two sides of the door leaf skeletons. Door leaf outer plates made of metal materials are arranged on the outer sides of the door leaf inner plates. The thermal insulation and fireproof door has the advantages that through the multilayered structure design of the door frame and the door leaves, the fireproof door can be effectively prevented from deforming, the fireproof effect is good, the manufacturing method is simple in step, and meanwhile the fireproof effect of the manufactured thermal insulation and fireproof door can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, and in particular relates to a heat-insulating fire-proof door and a manufacturing method thereof. Background technique [0002] Fire doors are an important part of fire-fighting equipment and an important part of social fire prevention. With the hot real estate industry and large-scale infrastructure construction, the market demand for fire doors will be greatly improved, but the market's fire protection requirements for fire doors will also increase accordingly. [0003] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. Fire doors are fire partitions with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It c...

Problems solved by technology

[0005] Although the above solution solves the problem of poor sound insulation effect in the prior art to a certain extent, the solution still exists: it is easy to be heated and deformed after a fire breaks out, so that heat leaks out of the fire door, reducing the heat insulation effect and poor fire prevention effect
