Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the improvement of studs used when constructing walls, particularly studs used in thin wall construction.

(Prior art) The conventional stud A for thin walls is formed by bending a metal plate along its longitudinal direction to form a substantially C-shaped cross section, as shown in Fig. 3. It is used by placing wall boards D on two opposing sides B and B.

However, in such a stud A, since its opening side end C is located within the gap E of the wall board D, depending on the position where the board D is screwed, etc., the acting force will cause damage to the two opposing faces described above. C and C are bent inward as shown by the broken lines in the figure, which not only makes it difficult to maintain the parallelism of both boards D, but also makes it impossible to ensure sufficient strength of the wall.

(Purpose) In view of these problems, the present invention provides a stud for thin walls that can easily ensure the parallelism of both boards forming the wall and also maintain sufficient strength of the wall. The purpose is to

(Structure of the present invention) In order to achieve the above-mentioned object, the present invention is a thin-walled stud made by bending a metal plate along its longitudinal direction. It has a first contact surface that comes into contact with the inner wall surface of one of the two wall boards to be stretched,
A first support surface that supports the space between the wall boards is connected to this first contact surface, and this first support surface has a
A second contact surface that extends in the same direction as the first contact surface and comes into contact with the inner surface of the other wall board is connected to the second contact surface. A folded second support surface is connected to the side of the board, and the second support surface extends in the direction of the extension of the first contact surface and comes into contact with the inner surface of the one wall board again. A third contact surface is connected to the contact surface, and this contact surface is further connected to a third support surface that is bent toward the other wall board, and this third support surface is connected to the third support surface. A fourth contact surface is formed by bending from the first end to the other end to extend toward the second contact surface and contact the inner surface of the other wall board. The abutment surface and the fourth abutment surface are characterized in that their tips are formed to have a length that contacts the second support surface.

(Example) Hereinafter, the present invention will be described in detail based on the illustrated example.

Figures 1 and 2 show a stud for thin walls according to an embodiment of the present invention, in which reference numeral 1 is a metal plate bent in its longitudinal direction; It is a stud formed in a figure 8 shape. First, this stud 1 has a first contact surface 4 on one end thereof which is in contact with the inner wall surface of one of the two wall boards 2 and 3 to be stretched.
have.

Reference numeral 5 denotes a first support surface that is vertically bent and connected to the first contact surface 4, and maintains the wall boards at a predetermined interval.

Reference numeral 6 denotes a second contact surface which is bent perpendicularly from the first support surface 5 in the direction of the first contact surface 4 and is connected to the inner surface of the other wall board 3. be touched.

Reference numeral 7 denotes a second support surface that is vertically bent from the second contact surface 6 toward the inner surface of one of the wall boards 2 described above, and is connected to both sides similarly to the first support surface 5. Maintain a predetermined distance between boards.

Reference numeral 8 denotes a third contact surface which is bent and connected perpendicularly from the second support surface 7 in the direction of the extension of the above-mentioned one side end, and is brought into contact with the inner surface of the above-mentioned one wall board 2. .

Reference numeral 9 denotes a third support surface that is vertically bent and connected from the third contact surface 8 toward the other wall board 3, similar to the first and second support surfaces 5 and 7. Maintain a specified distance between both wall boards.

Reference numeral 10 denotes a fourth abutment surface that is connected by bending a portion from the third support surface 9 to the other end of the metal plate vertically toward the second abutment surface 6; It comes into contact with the inner surface of the other wall board 3.

As seen in both figures, the first abutting surface 4 and the fourth abutting surface 10 formed on both sides of the metal plate face in opposite directions with a spacing between the supporting surfaces, and the tips thereof are It is substantially in contact with the intermediate second support surface 7. Further, the second abutting surface 6 and the third abutting surface 8 are also formed to have the same width. It goes without saying that each support surface 5, 7, 9 is formed to have the same width.

The stud 1 thus formed is cut to a predetermined length, and is erected by fitting its upper and lower ends into ceiling runners and floor runners (not shown) fixed at predetermined positions. Then, the wall panel board 2 is attached to the stud 1 with the first contact surface 4 and the third contact surface 4.
A screw is driven into a portion that abuts the abutting surface 8 of the third abutting surface 8 and is located on the third abutting surface 8. In the same way, the other side of the panel board 3 is placed on the second and fourth contact surfaces 6, 10 on the opposite side of the stud 1, and a screw is driven into the part of the panel board 3 located on the second contact surface 6. The wall is constructed using the following methods.

The wall constructed in this way does not have an open part between the boards when the board 2 on one side is fixed and then the board 3 on the other side is fixed, so the surface where the studs 1 are screwed, etc. Both boards 2 and 3 can be easily installed parallel to each other without bending.

Further, since both boards 2 and 3 are respectively abutted against two contact surfaces and supported by three support surfaces, sufficient strength can be obtained. In particular, the tip of the first contact surface 4 and the tip of the fourth contact surface 10 are
Since it is almost in contact with the support surface 7, it will not become flat even under shear stress.

(Effects) As described above, according to the present invention, each wall board to be stretched has two surfaces that come into contact with the inner surface, and the space between the two boards is supported by three supporting surfaces, Moreover, since there is no open part in the gap between the two boards, when the boards are screwed, etc., both boards can be easily maintained parallel during construction, and the strength is sufficient. In particular, it is possible to provide a stud that does not flatten even under stress in the shear direction.
