It is supported by nailing p1.

Thus, the space g on both sides of the vertical frame member d,
After laying floor panels p, p with a gap of g, conventionally, refractory materials k, k made of, for example, two gypsum boards are attached to both sides of the pillar materials c1, c2 to form the wall body w. It was
Further, the refractory material k passes through the void g and is continuous in the vertical direction to enhance the fire resistance and sound insulation of the wall body w.

[0006]

However, in the conventional one in which the refractory material k is attached after the floor panel p is laid, the laborious work of inserting and fixing the refractory material k in the space g is inevitable. However, there is a problem that the workability tends to be difficult and the workability is poor.

The present invention is based on the fact that a supporting metal member for supporting a mortar flow stop frame which is placed in a space between the vertical frame member and the beam member is fixed to the vertical frame member of the floor panel. An object of the present invention is to provide a structure of a fireproof wall body that does not require a work of inserting and fixing a fireproof material into the void and can save labor in construction.

[0008]

According to the present invention, a refractory material is provided on both sides of a vertical frame material having a steel beam and a wall base supported by the beam, so that the space on both sides is provided. A structure of a fire-resistant wall body having fire resistance, wherein a floor panel is provided on the upper surface of a frame in which both ends of a vertical frame member are joined to each other by a horizontal frame member in a rectangular shape. Is arranged in parallel to the outer surface of the vertical frame member with a space having a width in which the refractory material is disposed, and is fixed to the vertical frame member on the inner surface of the vertical frame member. Between the beam and the vertical frame member, the receiving piece of the supporting metal fitting has a standing piece and a receiving piece provided at the lower end thereof and having a length close to the beam through the lower surface of the vertical frame. A mortar flow stop frame placed in the space is supported.

[0009]

[Function] The floor panel is arranged between the vertical frame member and the beam member of the floor panel with a space having a width in which the refractory material is arranged, and the support metal fittings fixed to the vertical frame member. Thus, the mortar flow stop frame placed in the space is supported. In this way, by placing mortar in place of the refractory material between the floor panel and the beam material, in order to ensure the fire resistance and sound insulation of the refractory wall, insert the refractory material in the void. The laborious work of fixing can be eliminated, and the labor of construction can be saved.

The vertical frame member 6 has a notch 25 in which one side of the upper end portion of a wood material having a rectangular cross section is notched in a rectangular shape. Be nailed. Further, the vertical frame members 6, 6 are joined by a plurality of joists 26, which have both ends fitted in the notch 25 and are parallel to the horizontal frame member 7.

Further, on one of the vertical frame members 6A, a standing piece 11 is fixed to the inner surface of the vertical frame member 6A (the surface where the two vertical frame members 6 and 6 face each other) with a nail or the like, and the standing piece 11. A receiving piece 12 having a protruding portion 12A extending horizontally from the lower end of the piece 11 through the lower surface of the vertical frame member 6A and protruding from the vertical frame member 6A, and an edge of the protruding portion 12A of the receiving piece 12 to the upper surface of the flooring material 10 And a support metal fitting 13 composed of a rising piece 27 that rises to approximately the same height as that is provided over the entire length of the vertical frame member 6A.

It should be noted that between the standing piece 11 and the inner surface of the vertical frame member 6A, between the receiving piece 12 and the lower surface of the vertical frame member 6A, and the vertical frame member 6
A waterproof sheet 29 is continuously arranged on the outward surface of A.

The floor panel P has a width such that the vertical frame member 6A is parallel to the beam member 4 and the refractory material 3 is disposed between the beam member 4 and the outward surface of the vertical frame member 6A. Across the void 14,
It is fixed using a mounting bracket 32 to a large pull 31 that is attached to a beam member 30 made of a lattice beam extending from the pillar 17 at a right angle to the beam member 4.

The beam member 30 has a beam member 4 on its upper and lower surfaces.
In addition to the above, the Daihiki 31 is the lattice 3 of the beam 30.

The lower sheet portion 34A interposed between the upper surface of the receiving piece 12 and the first side sheet portion 3 that stands up along the outer surface of the vertical frame member 6A.
4B and a second side sheet portion 34C that rises from the edge of the receiving piece 12.

The waterproof sheet 34 has a core material on at least the second side sheet portion 34C so that the second side sheet portion 34C is held in an upright state. Alternatively, the waterproof sheet 34 may be formed using a relatively hard material.

The receiving piece 12 supports the flow stop frame 15 composed of the waterproof sheet 34, and the mortar M is cast on the flow stop frame 15.

FIG. 5 shows still another embodiment of the support fitting 13. In this example, the support fitting 13 passes through a vertical piece 6A of the floor panel P and a vertical piece 6A which is nailed to the inner surface of the vertical frame material 6A with a waterproof sheet 35 interposed therebetween. And a horizontal receiving piece 12 having a length close to the beam member 4
And a rising piece 37 rising from the edge of the receiving piece 12,
The rising piece 37 has a hanging piece 40 that is hung from the lower end of the rising piece 37 and is bolted to the strip 39 of the beam member 4. The receiving piece 1
2 and the hanging piece 40 are joined by a triangular rib 41 to reinforce the support fitting 13.

The waterproof sheet 35 is provided with a side sheet portion 35A which rises along the outer surface of the vertical frame member 6A, and the side sheet portion 35A, the receiving piece 12 and the rising piece 37 allow the space 14 to be formed. A flow stop frame 15 for the mortar M to be cast is formed.

The support fitting 13 of this embodiment is bolted to the beam 4 prior to laying the floor panel P.
