PURPOSE: An explosion-pressure relieving device for windows and doors is provided to increase effect of relieving explosion pressure by absorbing the explosion pressure in multi steps. The explosion pressure buffering effect can be increased. CONSTITUTION: An explosion-pressure relieving device(100) for windows and doors is as follows. The relieving device is formed by an extendable flat member and is installed on the opening of a building's wall. The flat member comprises a pair of coupling holes(111,121), a first relieving unit and a second relieving unit. The coupling holes are formed on the upper and lower parts of the central line of the member. The first relieving unit is formed along a first length perpendicular to the central line and starts cutting from the central part if explosion pressure is applied. The cutting is done on both sides of the first length. |
