Means for Solving the Problems In order to achieve the above object, the present invention relates to a tubular portion made of an elastic material whose cross section is partially open or closed to a gap between wall materials in a building. A fire-prevention iron plate material whose entirety is slightly larger than the width of the gap and has elasticity in the width direction, the ends of the tubular portions of the respective iron plate materials are fitted to each other. It is characterized in that it is inserted over substantially the entire length of the gap while being connected to each other.

Embodiment In FIGS. 1 and 2 showing an embodiment of the present invention, FIG.
(11) is a beam material constituting the upper chord material of the wall frame on the first floor,

In such a structure of the outer wall portion, the fireproof iron plate material (16) of the present invention is first inserted and mounted in the gap (15) between the front surface panels (13) and (14).
The outside thereof is filled with a caulking material (19) via an interposing material (17).

As shown in FIG. 3, the fire-prevention iron plate material (16) is formed by bending a spring steel plate into an approximately Ω shape, and as shown in FIG. (18) is inserted into the gap (15) such that the top is on the back side. In this case, the width (L) in the vertical direction when the circular cylindrical portion is inserted is slightly larger than the width of the gap (15).
When it is strongly pushed, it is contracted and inserted in the width direction, and is pressed against and held by the upper and lower wall portions of the gap (15) by its elastic reaction force. It should be noted that even when the circular cylindrical portion is inserted such that the top portion is on the upper side, it is also possible to contract and insert similarly.

And this fire prevention iron plate material (16) becomes a backup material at the time of filling the outside with the caulking material (19). The interposition material (17) is formed of, for example, a synthetic resin such as styrene foam resin, and is for preventing the caulking material (19) from being bonded to the fire-resistant iron plate (16). That is, when the caulking material (19) is adhered and held on the back surface side, it is bonded to the upper and lower surfaces and the back surface, thereby preventing cracks due to relative movement with the bonded counterpart. Therefore, when there is no possibility of such adhesion, there is no need to provide the interposition material (17).

As shown in FIG. 2, the above-mentioned fire-prevention iron plate (16) uses a slightly long one (16a) and a slightly short one (16b). After being installed in the gap (15), a short fire-resistant steel plate (16b) from outside
The short fire-resistant steel sheet (16) is replaced by a long fire-resistant steel sheet (16
a) Insert so as to close the seam between (16a). At this time, the short fire-prevention iron plate (16b) is fitted by fitting the circular tubular portion to the inside of the circular tubular portion of the long fire-prevention iron plate (16a). As a result, the gap (15) is filled in a hermetically closed state without any gap over substantially the entire length.

FIG. 4 is a view showing a fire-prevention iron plate material in which a spring steel plate is bent into a circular or elliptical cross-section with its entire cross-section being closed so that the ends thereof are double inward and outward, thereby making the whole elastic. 16). FIG. 5 also shows a case where the whole is bent in an inverted triangular cross section and both ends are bent outward to form a deformed Ω shape. In this case, it is inserted into the gap (15) in the state of the Ω shape.

Advantageous Effects of the Invention As described above, according to the present invention, the gap between the wall materials is closed by the fire-resistant iron plate material.
Even if the caulking material or the like on the outside burns down, this fire-resistant iron plate material functions as a fire stop for preventing the invasion of the flame, and a material excellent in fire resistance can be obtained.
Moreover, the fire-resistant iron plate material becomes a backup material when filling the caulking material on the outside, and since it is held at an arbitrary depth by its elasticity, there is no need to screw the base plate as in the conventional case. In addition, there is an advantage that the head of the screw is not exposed to the outside, or it is not necessary to perform a screw fixing operation with poor workability. In addition, according to the present invention, since the ends of the tubular portions of the respective iron plate members are connected while fitting each other, there is no gap between the iron plate members, and a more excellent fire prevention performance is obtained.
