材を用いるようにしたものである。 The expandable part of a building is separated into two skeletons, and the gap between the frames must be closed. For example, in the case of an exterior wall, an expansion joint cover is provided on the outdoor side. Even if this expansion joint cover is made of metal, it may not be sufficient from a fire prevention standpoint, and it is necessary to fill the gap between the frames with a fireproof material. However, since the gap between the expandable parts changes as the frame expands and contracts, there is a risk that the fireproofing material may fall off even if it is filled. Therefore, in the present invention, the fireproofing material that covers the gap is supported by the edging material so that the fireproofing material sufficiently closes the gap between the frames and does not fall off even if the building expands and contracts. A thermally expandable fire retardant material is used to completely fill the tank.
以下、本発明を添付する図面に示す具体的な実
施例に基いて詳細に説明する。 Hereinafter, the present invention will be described in detail based on specific embodiments shown in the accompanying drawings.

挾持溝６に挿入し挾持させて固定する。 In the extensible part of the building, the skeletons 1 and 1 face each other, and there is a gap 2. Anchor metal fittings 4 are fixed by welding to anchor bolts 3 protruding from the exterior side of the frame 1 near the gap 2 at appropriate intervals. The tip side of the anchor hardware 4 is bent parallel to the wall surface of the frame to form a supporting piece 5, and a cut-and-raised portion is provided thereto to form a clamping groove 6 for the edge material described below. The edging material 7 is a long extruded aluminum member with a roughly U-shaped cross section, and includes a horizontal base piece 8 in the figure, a hanging piece 9 that hangs down from the inner end of the base piece 8 toward the outdoors, and a hanging piece. 9
The holding piece 10 extends horizontally outward from the tip of the hanging piece 9 and the outside of the hanging piece 9 closer to the base piece 8 and the base piece 8.
The clamping groove 6 of the anchor hardware 4 is located indoors from the outer end.
An insertion piece 11 that fits into the base piece 8 is provided protrudingly, and a protrusion is provided on the inner end of the base piece 8, and a mounting piece 31 is formed perpendicularly to the support groove 12 on the outer end. This edge material 7 is fixed by inserting both insertion pieces 11 into both clamping grooves 6 of the anchor hardware 4 and clamping them.

する。 The frame is made of a thermally expandable fireproofing material 14, such as a thermally expandable material 13 (trade name: vermiculite), which expands 3 to 4 times in the thickness direction when heated to 400°C or higher, such as a thermally expandable material 13 containing ceramic fiber or an organic binder as a component. 1,
The gap 2 between 1 is curved and covered. The heat-expandable fireproofing material 14 of this embodiment is made by stacking two heat-expandable materials 13, and the outdoor surface is made of aluminum over the entire surface.
It is coated with a synthetic resin such as vinyl chloride or a rubber material to form a water stop plate 15, and a fall prevention protection material 16 such as a steel wire mesh is stretched over the entire surface of the indoor side to prevent the heat-expandable material 13 from falling. . This thermally expandable fireproofing material 14 is folded from sheet metal shown in FIG. Support part 17 held by saw teeth 18
is brought into contact with the holding piece 10 of the edge material 7 and screwed with the screw 20. The space between the support portion 17 of the protective piece 10 and the frame 1 is closed with a thermally expandable material 13 made of the same material as the thermally expandable fireproofing material 14 to form a fire barrier caulk 21.

A flat cover 25 is formed by tightening the aluminum interior plate 24 with screws or the like. This flat cover 25 is set to a size that covers the gap between the frames 1, 1, and is brought into contact with the base piece 8 of the edge material 7 by inserting a gasket 26 into the base piece 8 of the edge material 7 with its protrusion 27 inserted into the support groove 23. The end of the W-shaped spring clip 28 is engaged with the support groove 12 of No. 2, and the bolt 29 inserted from the outdoor side of the flat cover 25 to the indoor side is screwed into the roller nut 30 attached to the center of the spring clip 28. Fix it. The gasket 26 is located between the side of the flat cover 25 and the mounting piece 12 of the edge member 7 to provide elasticity to the device and at the same time provide a watertight structure.

Covered with thermally expandable fireproofing material integrated with the water stop plate,
This is an expansion joint device for a building in which the fireproofing material is supported by the edging material, and in the present invention, even if the building expands and contracts, the fireproofing material sufficiently closes the gap between the building blocks and does not fall off. Also,
Even in the unlikely event that a fire occurs, the thermally expandable fireproofing material expands and completely fills the gaps in the structure, making it extremely effective in preventing fires. Since the fireproof material of the present invention also serves as a water stop plate, there is no need to provide a separate water stop plate, and an expansion joint device for a building can be provided at a low cost. moreover,
In the present invention, since the fireproofing material is covered with fall prevention protection material such as steel wire mesh over the entire surface, there is no fall of the fireproofing material. Furthermore, in the present invention, since the fireproofing material is attached to the edge material via the holding metal fittings, attachment of the fireproofing material is extremely easy.
