A sliding fire door is disclosed with an improved tightness of the closure by the door main body. The sliding fire door includes an opening frame, a fire door, and a guiding mechanism. The guiding mechanism includes a guide roller group which includes a plurality of guide rollers arranged one adjacent to another along the slide direction and which is configured to guide the door main body. The guiding mechanism is configured to guide the door main body such that the door main body is moved from an opening position to a closing position. The door main body has a first opposing surface which is oriented toward the wall. The opening frame has a second opposing surface which is oriented toward the first opposing surface of the door main body in the closing position. The guiding mechanism moves the door main body to cause the first opposing surface to be moved closer to the second opposing surface when the door main body is moved from the opening position to the closing position.

Sliding fire door

A fire door includes an intermediate member formed in the shape of a plate and arranged between a first plate member and a second plate member; a first heat insulating material arranged between the first plate member and the intermediate member; a second heat insulating material arranged between the second plate member and the intermediate member; a first coupling member for coupling the first plate member and the intermediate member, arranged so as to extend through the first heat insulating material; and a second coupling member for coupling the second plate member and the intermediate member, arranged so as to extend through the second heat insulating material. The first coupling member is arranged so as to be spaced away from both of the second plate member and the second coupling member. The second coupling member is arranged so as to be spaced away from the first plate member, and the first plate member and the second plate member are arranged so as to be spaced away from each other.

Fire door

A door body includes a door main body, an upper guided portion provided to an upper portion of the door main body, and a lower guided portion provided to a lower portion of the door main body. A guide member includes an upper guide portion, a lower guide portion, and a restricting portion. The upper guide portion supports the upper guided portion from below while restricting movement of the upper guided portion along the fore and aft direction. The lower guide portion supports the lower guided portion from below while restricting movement of the lower guided portion along the fore and aft direction. The upper guided portion is moved upwardly away from the upper guide portion in the expanded support state. The restricting portion restricts movement of the door main body in the first direction in the expanded support state, and restricts movement of the door main body in the second direction in the expanded support state.

A centralized management system for managing maintenance parts of machines at multiple plants includes: a warehouse facility for providing a concentrated storage of the maintenance parts for multiple types of the machines at multiple plants; a necessary parts management device for managing whether the maintenance parts are required for the machine; and a parts shipment management device for determining the maintenance parts to be shipped from the warehouse facility based on management information in the necessary parts management device. The present invention provides a system for managing maintenance parts that allows management costs to be restricted while allowing changes in the status of machines at plants to be handled in a flexible manner.
