Fire door

Abstract

The invention provides a fire door which comprises an outer door panel, an inner door panel and a frame used for connecting the outer door panel with the inner door panel, wherein the outer surface of the outer door panel and the outer surface of the inner door panel are coated with flame-retardant paint layers; two pieces of fire-proof glass are respectively arranged on the inner sides of the outer door panel and the inner door panel; fire-proof insulation boards are respectively arranged between the outer door panel and one piece of fire-proof glass and between the inner door panel and the other piece of fire-proof glass; a framework is arranged between the two pieces of fire-proof glass and used for supporting the fire-proof glass; the interior of the framework is filled with fire-proof materials. The fire door has the benefits that the framework is arranged between the two pieces of fire-proof glass and used for supporting the fire-proof glass, the fire-proof glass on the inner sides of the outer door panel and the inner door panel plays a role of fire protection, and the fire-proof insulation boards are respectively arranged between the outer door panel and one piece of fire-proof glass and between the inner door panel and the other piece of fire-proof glass, which play a role of sound insulation; the fire door has the advantages of simple structure, safety in use, fire protection, sound insulation and the like.

Description

technical field [0001] The invention belongs to the technical field of building safety and fire prevention, and in particular relates to a fire door. Background technique [0002] Fire doors are one of the measures for building fire separation, and they are commonly found in high-rise buildings. In the existing technology, the main materials of fire doors are mostly made of wood plywood and metal plates, and some fire doors are made of wood materials in structure. Too many and some fire doors do not wrap the wooden material at the door frame, so the flame retardant and heat insulation effects are relatively poor, and most fire doors only have the function of flame retardant, and there are fire doors with single functions that cannot meet the diverse needs of users and other technical issues. Contents of the invention [0003] The problem to be solved by the present invention is to provide a fire door with simple structure and safe use, which is especially suitable for hig...
