Abstract

PURPOSE:To surely prevent smoke from coming in through between the inside surface of a fire frame and the outer periphery of a fire door when a fire has broken out. CONSTITUTION:The inner surface of a fire transom 4 and a fire mullion which constitute a fire frame is formed into a hook-like shape comprising an inner surface extending outward and one extending inward, wherein a C-shape is formed by a fixing piece 61 and a fin piece 62 on the inner surface extending inward. A fireproof seal material 60 having fireproof expansion material 63 is provided and a fireproof expansion material 64 is attached to the outer surfaces of a fire upper rail 11 and a fire stile of a fire door. In the case of a fire, the materials 63, 64 expand so that the gap between the fire frame and fire door is filled with the fin piece to prevent leak to the outside.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire door in which a door is attached to a frame so that the door can be opened and closed.

[0002]

2. Description of the Related Art As shown in Japanese Patent Laid-Open No. 61-75189, a refractory thermal expansion material and a sealing material are arranged in a door-contact portion of the frame facing in-plane direction so as to face the in-plane side surface of the door. There is known a fire door in which a fire-resistant thermal expansion material expands during a fire to close a gap between a door contact portion of a frame and an in-plane side surface of the door to prevent smoke from entering.

[0003]

In such a fire door, since the heat and heat resistant expansion material is mounted closer to the outside than the seal material, the fire and heat resistant expansion material expanded at the time of a fire is the door stop portion of the frame and the surface of the door. Not only is the gap leaked to the outside through the gap with the inward side face, the gap is insufficiently closed, but also the gap between the inner surface facing the frame out-of-plane direction and the outer peripheral surface of the door cannot be closed, and smoke is not generated. Intrusion cannot be reliably prevented.

Therefore, an object of the present invention is to provide a fire door that can solve the above-mentioned problems.

[0005]

[Means for Solving the Problems] The inner surface of the fireproof frame 8 is formed into a hook shape by the inner surface facing in the in-plane direction and the inner surface facing in the out-of-plane direction, and the inner surfaces facing in the in-plane direction are door stop portions 26, 46. A fireproof door 10 is attached to the fireproof frame 8 so as to be openable and closable, and a mounting piece 61 of a fireproof sealing material 60 having a substantially C shape with a mounting piece 61 and a fin piece 62 is attached to the door stop portion of the fireproof frame 8. The piece 62 is attached so as to face one side surface in the in-plane direction of the fire door 10 and face the inner surface of the fire prevention frame 8 facing the out-of-plane direction.
1. A fire door in which a heat and heat resistant expansion material 63 is attached to 1, and a heat and heat resistant expansion material 64 is attached to the outer peripheral surface of the fire door 10 so as to face the inner surface of the fire protection frame 8 facing outward.

[0006]

[Operation] When a fire occurs, the refractory heat expansion material 63 and the fire resistance heat expansion material 64 expand, and the fire resistance heat expansion material 63 provided in the door stop portion is prevented from leaking to the outside by the fin piece 62 of the fire resistance sealing material 60. In the gap between the inner surface of the fireproof frame 8 facing the out-of-plane direction and the outer peripheral surface of the fireproof door 10, and between the door contact portions 26, 46 of the fireproof frame 8 and the side surface of the fireproof door 10 in the out-of-plane direction, the heat resistant thermal expansion material 63 is provided. , 64 are fully filled and can be reliably blocked, and smoke can be reliably prevented from entering during a fire.

It has an inner surface 25 facing inward, and the inner surface 25 facing in the vertical in-plane direction is a door stop portion 26. The decorative material 23 may be attached in a snap type without being screwed. As shown in FIG. 2, the fireproof upper frame 11 is formed by attaching a fireproof plate 31 such as a calcium silicate plate to both side surfaces in the out-of-plane direction and the upper surface in the in-plane direction with a screw or a fire-resistant adhesive as shown in FIG. A glass mounting recess 32 is provided in the lower part in the direction, and a pair of decorative members 33, 33 made of aluminum and having a U-shape are attached to the outer peripheral surface of the fireproof plate 31 with screws. The decorative material 33 may be attached in a snap type without being screwed.

As shown in FIG. 3, the door mounting opening portion 7 of the fire prevention cubicle 5 is formed on both sides of the steel core 40 in the out-of-plane direction and on both sides of the in-plane direction inner surface and the in-plane direction outer surface. A refractory plate 41 such as a calcium silicate plate is attached with a screw or a refractory adhesive, and a glass mounting recess 42 is provided outside in the in-plane direction, and the outer peripheral surface of the refractory plate 41 is a U-shaped surface made of aluminum. A pair of outward facing decorative materials 43, 43 are attached with screws, and the inner surface in the in-plane direction of the fire protection cube 5, that is, the inner surface of the fire protection frame 8 becomes a hook shape, and the inner surface 44 facing in the out-of-plane direction and the in-plane direction. The door has a facing inner surface 45, and the in-plane 45 that faces the in-plane direction is a door-stop portion 46. The decorative material 43 may be attached in a snap type without being screwed. The fire protection vertical frame 13 is shown in FIG.
As shown in FIG. 5, a fireproof plate 51 such as a calcium silicate plate is attached with screws or a fireproof adhesive to both the in-plane direction outer surfaces and the in-plane direction outer surface of the steel core material 50, and the glass mounting recess 52 is provided in the in-plane direction. On the outer peripheral surface of the refractory plate 51, a pair of decorative members 53, 53 made of aluminum and having a U-shape in the out-of-plane direction are attached by screws. The decorative material 53 may be attached in a snap type without being screwed.

As shown in FIGS. 2 and 3, a fireproof sealant 60 such as a sintered gasket is attached to each of the doorstop portion 26 of the fireproof blind 4 and the doorstop portion 46 of the fireproof cubic 5 and the fireproof sealant 60 is provided. The sealing material 60 has a mounting piece 61 and a fin piece 62 which are substantially C-shaped, and the mounting piece 61 is attached to the door stop portions 26 and 46 to form the fin piece 6.
2 is attached so as to face the inner surface 24 facing the out-of-plane direction, and the mounting piece 61 has a heat-resistant thermal expansion material 63 such as Inchmex (trade name) mounted toward the fin piece 62.

On the outer peripheral surface of No. 0, a refractory thermal expansion material 64 such as Inchmex (trade name) is attached.

Because of this, in the event of a fire, the refractory heat expanders 63 and 64 expand and the gap between the upper and side surfaces of the upper fire-protection frame 11 and the inner surfaces 24 and 25 of the fire-prevention blind 4 and the vertical fire-control frame 13
Are filled between the side surfaces and the end surfaces and the inner surfaces 44 and 45 of the fire prevention cubicle 5 to close each gap and prevent smoke and the like from flowing. At this time, the refractory heat-expansion material 63 provided on the fire-resistant seal material 60 is regulated by the fin pieces 62 so as to expand toward the back side, so that the gap is reliably filled without leaking to the outside. Since a pair of fireproof doors 10 and 10 are attached in the above embodiment, as shown in FIG. 4, a fireproof vertical frame 13 serving as a joining frame has the same fireproofness on both sides in the inboard direction as one of the inboard directions. The fireproof sealant 60 having the thermal expansion material 63 is attached. However, when the number of the fireproof doors 10 is one, the fireproof sealant 60 having the fireproof thermal expansion material 63 on the left and right fireproof vertical frames 13 as shown in FIG. Should be installed. In addition, fire-resistant bottom frame 12
