Abstract

The invention discloses a fire door. The fire door comprises a fire door body, wherein an inner cavity and a device cavity are formed in the fire door body, the device cavity does not communicate withthe inner cavity, the device cavity is located at the center of the inner cavity, built-in filling pipes are arranged in the inner cavity, and the device cavity communicates with the one built-in filling pipe through the other built-in filling pipe; a plurality of discharging holes are formed in the side wall of the fire door body in a penetrating manner, discharging pipes are arranged in the plurality of discharging holes, and the plurality of discharging pipes communicate with the one built-in filling pipe; and a device barrel is arranged in the device cavity, the device barrel is fixedly connected with the inner wall of the device cavity through a connecting device, and a storage groove is formed in the device barrel. The fire door has the advantages of being reasonable in structural design, and capable of spraying fire-fighting foam to block the door seam when a fire occurs.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a fire door. Background technique [0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. In addition to the function of ordinary doors, it also has the function of preventing the spread of fire and smoke.
