BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stud used as a base structural material in, for example, inner wall construction.

[0002]

2. Description of the Related Art Conventionally, a stud 3 having a sectional structure shown in FIG.
It has been known. The stud 3 is formed by forming a long metal plate material into a cylindrical body 3M having a rectangular cross section. This cylinder 3M
Is formed by forming a side edge portion 3m on one side surface portion 3b of the metal plate member into a U shape to provide a U-shaped portion 3n, and the other side edge portion 3p is sandwiched at the tip by the U-shaped portion 3n. Thus, the folded portion 31 is provided on the one side surface 3b of the cylindrical body 3M by being entangled and formed into a U shape.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In finishing the inner wall of a concrete slab wall of a building on the room side, it is required to make the thickness of the inner wall as small as possible in order to increase the size of the room. However, according to the conventional stud, since the one side surface portion 3c facing the folded portion 31 is simply flat structure, the strength is weak, and especially when the stud thickness W is reduced, the stud is not attached to the stud as shown in FIG. Load P
However, the side surface 3c on the opposite side is extremely weak as compared with the side surface 3b on the side of the folded portion 31, so that twisting due to the load P occurs, which is unsuitable for use as a wall structure in interior wall construction, for example. Met.

The present invention has been made in order to solve the above problems, and provides a stud having high strength even when the stud thickness is made as small as possible.

[0005]

In the stud according to the present invention, a metal plate material is molded as a tubular body 3M having a rectangular cross section, and one side edge portion 3m of the metal plate material is molded into a U shape.
In the stud in which the folded portion 31 is provided on the one side surface 3b of the cylindrical body 3M by providing the character portion 3n and entwining the other side edge portion 3p so that the tip is sandwiched by the U-shaped portion, The other side surface portion 3c on the side opposite to the folded portion 31
The metal plate is projected inward, and the side surface portion 3
The reinforcing portion 32 formed by being deformed along the inner surface of c is provided.

[0006]

According to the stud of the present invention, the stud thickness can be reduced because the folded portions and the reinforcing portions are provided on both side surface portions where the highest strength is required against the load.

[0007]

EXAMPLES The following Figure 1 an embodiment of the present invention the stud 乃
This will be described with reference to FIGS. In each drawing, 3 is a stud, and this stud 3 is formed by forming a long metal plate material into a cylindrical body 3M having a rectangular cross section. In this cylindrical body 3M, a side edge portion 3m on one side surface portion 3b of the metal plate material is formed into a U shape to provide a U-shaped portion 3n, and the other side edge portion 3p is provided at the tip of the U-shaped portion 3n. By being entangled so as to be sandwiched and molded into a U-shape, one side surface portion 3b of the cylindrical body 3M
The folding portion 31 is provided at the bottom. Inner surface 3q of the side surface portion 3b
As shown in FIGS. 2 and 3, when the metal plate material is engaged with the roll forming die, the metal plate material is pressure-bonded so as to have the uneven portion 3h. The metal plate material is projected inward from the central portion 3e side of the other side surface portion 3c opposite to the folding portion 31, and is branched leftward and rightward, and the branching portions 3f and 3f are the side surface portions 3c. The reinforcing portion 32 formed by three layers is formed by deforming along the inner surface 3g. In this case as well, as shown in FIGS. 4 and 5, the concavo-convex portion 3j is formed on the inner surface 3i of the side surface portion 3c by the roll forming die.

As described above, by providing the folded portion 31 and the reinforcing portion 32 on both side surface portions 3b and 3c, respectively,
The thickness of each metal plate is four, three, that is, four times, three.
Since the strength is doubled and the strength against the load P on the stud 3 is significantly increased, the strength of the stud can be secured even if the stud thickness W is reduced.

Next, an example of construction of the inner wall of the room using the stud of the present invention will be described with reference to FIG. First, the runner 4 having a U-shaped cross section is attached to the ceiling side and the floor side of the surface of the concrete wall body 2 through the gap B. At this time, the runner 4 is previously attached according to the finished surface of the wall. Runner 4 above
The upper and lower ends of the stud 3 are inserted into the engaging groove portion 4a.
In this case, the studs are arranged at predetermined intervals. After that, the board 1 is fixed to the surface 3a side of the stud 3 using the fastening member 5. Thus, since the stud of the present invention having a small stud thickness can be used, the room can be enlarged.

Further, according to the above embodiment, the inner surface 3i of the side surface portion 3c having the reinforcing portion 32 is crimped with the uneven portion 3j, but as shown in FIG. 5, the flat surface is crimped without the uneven portion 3j. You may shape | mold as the support part 3d.

[0011]

According to the stud of the present invention, a metal plate is projected inward on the other side surface opposite to the folded portion and is deformed along the inner surface of the side surface. Since the reinforcing portion is provided, a stud having high strength can be obtained.
