Single wooden heat insulation fireproof door with window

Abstract

The invention provides a single wooden heat insulation fireproof door with a window. A peripheral skeleton of a door leaf is divided into multiple areas by an inner skeleton of the door leaf; the multiple areas are filled with expanded perlite fireproof plates to form a door core; a first magnesium-silicon fireproof plate is fixedly arranged on the surface of the door core; first flame-retardant plywood is fixedly arranged on the surface of the first magnesium-silicon fireproof plate; a doorframe comprises a frame formed by four pieces of flame-retardant wood; a second magnesium-silicon fireproof plate and second flame-retardant plywood are fixedly arranged on the surface, exposed to fire, of the frame, and are combined with the frame to form a door stop line; fireproof expansion sealing elements are arranged on the contact surface of the doorframe and the door leaf, and are fixedly embedded into the doorframe. The expanded perlite fireproof plates are arranged in the door leaf, so that fireproof effects are improved; the magnesium-silicon fireproof plates are arranged, so that the fireproof effects are further improved, and meanwhile, the strength and the impact resistance of the door leaf are improved; the fireproof expansion sealing elements are reasonably arranged on the doorframe, so that sealing and fireproof effects are improved.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a wooden heat-insulating fire door with a single opening and a window. Background technique [0002] With the country's large-scale infrastructure construction (such as subways, expanded airports and stadiums), the demand for fire doors used in buildings is increasing, the performance requirements are getting higher and higher, and the fire protection alert level requirements are getting higher and higher. [0003] At present, the fire doors used in densely populated places, homes, and clubs have a high thermal conductivity. When a fire occurs, the temperature of the door leaf is likely to be too high, resulting in the door leaf being easily deformed and failing to meet the requirements of fire performance. In addition, the strength of traditional fire doors Poor, its impact resistance also needs to be improved. Contents of the invention [0004] Aiming at the deficiencies ...
