Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stud used as a base structural material in the interior wall construction, for example.

[0002]

[Prior art]

 Conventionally, a stud 3 having a sectional structure shown in FIG. 6 is known. The stud 3 is formed by forming a long metal plate material into a tubular 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 form a U-shaped portion 3n, and the other side edge portion 3p is formed on the U-shaped portion 3n. By forming the U-shape by twisting the tip so as to be clamped, a folded portion 31 is provided on one side surface 3b of the cylindrical body 3M.

[0003]

[Problems to be solved by the device]

 In finishing the inner wall of the concrete frame wall of the building on the room side, it is required to make the inner wall thickness as small as possible in order to make the room larger. 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, as shown in FIG. It is weak against the load P against, and the side face 3c on the opposite side is extremely weak compared to the side face 3b on the side of the folded seam 31 so that twisting occurs due to the load P. For example, it is used as a wall structure in interior wall construction. It was unsuitable to do.

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]

[Means for Solving the Problems]

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

[0006]

[Action]

 According to the stud of the present invention, the fold thickness and the reinforcing portion are provided on both side surface portions, which are required to have the highest strength against a load, so that the stud thickness can be reduced.

[0007]

【Example】

 An embodiment of the stud of the present invention will be described below with reference to FIGS. 1 to 5. 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 of one side surface portion 3b of a 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 folding them so as to be sandwiched and forming them into a U-shape, a folding portion 31 is provided on one side surface portion 3b of the cylindrical body 3M. As shown in FIGS. 2 and 3, the inner surface 3q of the side surface portion 3b is pressure-bonded so that an uneven portion 3h is formed when the metal plate material is engaged with the roll forming die. The metal plate material is projected inward from the central portion 3e side of the other side surface portion 3c on the side opposite to the folding portion 31, and is branched leftward and rightward so that the branching portions 3f and 3f are the side surface portions. A reinforcing portion 32 is provided which is deformed along the inner surface 3g of 3c to form three layers. Also in this case, 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 portions 31 and the reinforcing portions 32 on the side surface portions 3b and 3c respectively, the thickness of each metal plate material 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, a construction example 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 should be attached beforehand according to the finished surface of the wall. The upper and lower ends of the stud 3 are inserted into the engaging groove portion 4a of the runner 4. 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. In this way, 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-mentioned 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, it is crimped without the uneven portion 3j. You may shape | mold as the support part 3d.

[0011]

[Effect of device]

 According to the stud of the present invention, a reinforcing portion formed by projecting a metal plate inward and deforming along the inner surface of the side surface portion is provided on the other side surface portion on the side opposite to the folded portion. Since it is provided, a stud with high strength can be obtained.
