Description

  The present invention relates to an opening device that is provided in an opening of a building and has improved fire resistance, and a fire prevention member that is provided in the opening device.

  Buildings such as houses are required to have high fire resistance so that damage such as fire spread can be minimized in the event of a fire. Since there is no wall at the opening of the building, fire resistance tends to be lower than that of the wall. Therefore, it is possible to increase the fire resistance of the opening by providing the opening device such as a window or a door disposed in the opening with high fire resistance.

  In such an opening device, fire resistance becomes a problem in a portion communicating with the interior and the exterior. That is, the indoor or outdoor flame penetrates from the communicating part to the opposite side and promotes the spread of fire. Examples of the communicating portion include a hole through which a shaft connecting handles (handles) provided inside and outside the door is passed (hereinafter, referred to as “handle hole”). .

  Patent Document 1 discloses a fire door structure including a thermal expansion body between an escutcheon plate (handle base) provided on the front and back surfaces of the door body and the door body. According to this, when the door is heated by a fire or the like, the thermal expansion body expands and closes the handle hole, so that it is possible to prevent the spread of fire.
