Intelligent fire-extinguishing fireproof door

Abstract

An intelligent fire-extinguishing fireproof door comprises a door plate and a door frame, wherein a water pipe is arranged in the part, at the upper end of the door plate, of the door frame and tightly attached to the inner wall of the door frame, an electric control valve is arranged at the water inlet end of the water pipe, and a temperature sensor and a smoke sensor are installed at the top ofthe door frame. A hollow inner cavity is formed in the door plate; the water pipe is connected with a water distributor positioned at the upper part of the hollow inner cavity through a middle pipe; the water distributor comprises an oval outer ring pipe, an oval inner ring pipe and a connecting pipe, the outer ring pipe and the inner ring pipe are connected through the connecting pipe, and the outer ring pipe, the inner ring pipe and the connecting pipe are each evenly provided with a plurality of water outlet holes. The fireproof door has the beneficial effects that the fire resistance of the fireproof door can be improved through an explosion-proof plate and a fireproof sound insulation plate, the sound absorption effect can be enhanced through the sound insulation material filling thesecond supporting frame, and the fireproof door has the advantages of being simple in structure, safe to use, fireproof, sound-proof and the like.

Description

technical field [0001] The invention relates to the technical field of fireproof building materials, in particular to an intelligent fire-extinguishing fireproof door. Background technique [0002] Fire doors are widely used in various buildings. According to the national standard GB12955-2008 "Fire Doors", fire doors can be divided into four categories: steel fire doors, wooden fire doors, steel and wood fire doors and other materials fire doors. Among them, the steel fire door is made of steel materials to make the door frame, door frame and door panel, and the wooden fire door is made of flame-retardant wood or wood products to make the door frame, door frame and door panel, and the steel-wood fire door is made of steel and Fire-resistant wood materials or fire-resistant wood products are used to make door frames, door leaf frames and door leaf panels. Fire doors made of other materials are made of inorganic non-combustible materials other than steel, fire-resistant wood ...

AI Technical Summary
