Embodiment

[0012] Example: see figure 1 , a composite fire door, comprising a door leaf, a door frame 2 and a hinge 3, one side of the door leaf is hinged to the door frame 2 through the hinge 3. The door leaf includes a frame body 11 formed by a panel, a back panel and a side panel, and the panel, the back panel and the side panels are all metal plates or fireproof decorative panels; during specific implementation, a metal plate, such as a stainless steel plate, etc. is selected, and the structure Greater stability. In the frame body 11, a fire-proof frame 12 is respectively provided near the two side panels. Alternately distributed and bonded together by high temperature resistant glue, the cavity formed by the front panel, the back panel and the two fireproof skeletons 12 is filled with inorganic fireproof core material boards 13 . The inorganic fireproof core board 13 adopts existing products, such as the fireproof core board disclosed in the patent (patent number: ZL 201110229683....

Abstract

The invention discloses a composite fireproof door which comprises a door leaf, a door frame and hinges. The door leaf comprises a frame body formed by a faceplate, a backplate and two side plates, fireproof frameworks are arranged at positions, close to the side plates, in the frame body, a cavity formed by the faceplate, the backplate and the fireproof frameworks is filled with inorganic fireproof core material plates, the door frame is filled with fireproof plates and multilayer plates which are distributed alternately and bonded through high-temperature-resistant glue, and section of the door frame is in the shape of a step; when the door leaf is closed, two sides of the door leaf are positioned in the step of the door frame, so that the door leaf is integrally embedded in the door frame. Heat insulating performance can be improved, and deformation can be avoided, so that fireproof performance is improved.

Description

technical field [0001] The invention relates to a fireproof door, in particular to a composite fireproof door. Background technique [0002] Traditional wooden fire doors use a large amount of original ecological wood as raw materials for fire door production. With the restrictions on the use of original ecological wood at home and abroad, the production and sales of ordinary wooden fire doors will be restricted. Traditional steel fire doors are made of all steel materials. The fire and heat insulation performance of steel fire doors is a huge test for steel fire doors, and the existing steel fire door core materials are severely corrosive to steel plates. A large number of steel fire doors have been rusted in less than 2 years since they were installed and used on site. At the same time, the thermal conductivity of the traditional steel fire door plate is high, and when a fire occurs, it is easy to cause the temperature of the back fire surface to be high, which cannot m...
