Abstract

The invention relates to a fire-retardant door comprising fire-retardant glass and a supporting part, wherein the supporting part is used for supporting the fire-retardant glass and comprises elastic members, reinforcing frames and fixed plates, wherein the elastic members contact with two surfaces of the edge of the fire-retardant glass; the reinforcing frames are used for supporting the elastic members; and the fixed plates are fixed on a bracket and correspond to two surfaces of the reinforcing frames. The fire-retardant door has A-grade fire-retardant property.

Description

technical field [0001] The invention relates to a fire door, more specifically, to a fire door with Class A fire performance. Background technique [0002] Generally, a fire door refers to a door with fire resistance. Fire doors play the role of gaining time for people to escape from the fire, preventing the spread of fire, delaying the spread of fire and resisting fire for a certain period of time. Fire doors are classified according to their fire resistance. [0003] Here, the Class A fire performance of the fire door means that the fire resistance performance can be ensured for 1 hour or more according to the test results of Korean Industrial Standards stipulated in the Industrial Standards Act. [0004] A conventional fire door on which glass is used is resistant to fire for 1 hour or more and is mainly formed of steel, so it is generally used only as a front door. [0005] If this kind of door is applied to the room door, it can effectively resist the spread of fire,...
