The face material 9 is also divided into a rectangular shape, and its upper edge terminates beyond the roof beam 13.

  The boundary wall 1c of the shed is fixed to the upper surface side of the roof beam 13 and is horizontally fixed to the lower runner 5 and the lower surface of the rafter 14 having a gradient, thereby having the same gradient as the rafter 14. A fire-resistant face material 9 is fixed to both sides of a frame composed of a horizontal upper runner 7 and a plurality of studs 8 fitted between them and extending in the vertical direction and spaced apart in the horizontal direction. . The face material 9 is divided into a triangle or a trapezoid. The rafter 14 is supported by a purlin 16 fixed by a bundle 15.

  As shown in FIG. 4, the boundary wall 1c on the back of the hut is representatively shown, the lower runner 5 and the upper runner 7 used in each of the boundary walls 1a, 1b and 1c are respectively a pair of flanges 18 and their flanges. It is made of light iron grooved steel having a U-shaped cross section including a web 19 that is connected to the other. Further, the upper runner 7 and the lower runner 5 are fixed to predetermined members with their groove portions facing each other.

  In each of the boundary walls 1a, 1b, and 1c, the stud 8 is disposed between the lower runner 5 and the upper runner 7 with an interval in the horizontal direction. As shown in FIG. 3, the stud 8 is fixed to only one of the surface material 9A on the dwelling unit A side or the surface material 9B on the dwelling unit B side by screws, and is fixed to the surface materials 9A and 9B on both sides. Not. Thereby, for example, vibration on the dwelling unit A side is prevented from being transmitted to the dwelling unit B side via the face material 9 and the stud 8. In the present embodiment, the studs 8 are arranged in a staggered manner between the face materials 9A and 9B, and a heat insulating material 20 such as rock wool is arranged therebetween.

  As shown in FIG. 1, for example, square studs are used for the first floor portion of the boundary wall 1 a and the second floor portion of the boundary wall 1 b. The square stud is a cylindrical body having a rectangular cross section, and is used that has been cut to a required length in advance. That is, the stud 8 whose length does not change is used for the boundary wall 1a of the first floor portion and the boundary wall 1b of the second floor portion.

  On the other hand, as shown in FIG. 4, the boundary wall 1 c at the back of the hut includes a variable-length stud 30 whose length can be adjusted. As further enlarged in FIG. 5, the variable-length stud 30 includes a main body portion 32 and an adjuster 34 inserted into the main body portion 32.

  FIG. 6 shows a cross-sectional view of the main body 32. The main body 32 is composed of a pair of long side portions 32a facing each other and a pair of short side portions 32b having a length shorter than the long side portion 32a, and has a rectangular shape with a closed cross section. The main body of the present embodiment has a closed cross section obtained by bending a steel plate into a rectangular shape and fixing both edges thereof. However, the main body 32 is not limited to such a form.

  As shown in FIG. 5 and FIG. 7, which is a cross-sectional view of the adjuster 34, the adjuster 34 has an open cross section with a notch 22 extending in the longitudinal direction. The adjuster 34 is formed, for example, by bending a steel plate having a thickness t of about 0.5 mm. When the adjuster 34 is inserted into the main body 32, the cross section of the main body 32 extends along the pair of side walls 34 a along the short side 32 b and the side walls 34 a, 34 a and along one long side 32 a of the main body 32. It is substantially C-shaped having a wall 34b. The side wall portion 34a of the present embodiment is provided with a return portion 34c extending along the long side portion 32a of the main body portion 32 on the side of the notch portion 22 with a small length.

  Further, as shown in FIGS. 6 and 7, the adjuster 34 of the present embodiment has a dimension W2 between the pair of side wall portions 34 a and 34 a on the notch portion 22 side on the inner peripheral surface i of the main body portion 32. It is formed larger than the dimension W1 between the short side portions 32b and 32b. The dimension W3 between the pair of side wall portions 34a, 34a on the side where the notch 22 of the adjuster 34 is not provided is formed to be slightly smaller than the dimension W1 of the main body portion 32. Further, the length L2 of the side wall portion 34a of the adjuster 34 is also formed slightly smaller than the length L1 of the inner peripheral surface i of the short side portion 32b of the main body portion 32.

  Such a variable length stud 30 can be inserted into the main body portion 32 by elastically deforming the pair of side wall portions 34a and 34a of the adjuster 34 in the direction of narrowing the notch portion 22 of the adjuster 34, that is, in the direction of approaching each other. . The adjuster 34 inserted into the main body 32 comes into strong contact with the inner peripheral surface i of the main body 32 by restoring elastic deformation. The adjuster 34 is fixed to the main body 32 by the frictional force at the time of contact.

  The stud 8 is used as a base material for fixing the face material 9 and does not bear a vertical load between the lower runner 5 and the upper runner 7. Therefore, in the variable-length stud 30, the adjuster 34 and the main body 32 are "fixed" when the stud 8 is built between the lower runner 5 and the upper runner 7 and the length of the stud 8 is fixed. If the position of the main body part 32 and the adjuster 34 is maintained to such an extent that is maintained and does not change easily, it is intended.

As described above, the variable length stud 30 of this embodiment can obtain a plurality of types of studs 8 having different lengths by adjusting the overlapping length of the main body portion 32 and the adjuster 34. In addition, since the main body 32 and the adjuster 34 are fixed by both frictional forces, a plurality of types of studs 8 having different lengths can be easily obtained on site while eliminating the need for special processing or on-site cutting work. Can be obtained. Therefore, the productivity of the partition wall can be greatly improved by using the stud 8 of the present embodiment.

  As shown in FIG. 8, in the variable-length stud 30, when the overlapping length Ya between the main body portion 32 and the adjuster 34 is reduced, the above-described frictional force, bending strength, and the like may be significantly reduced. For this reason, the variable length stud 30 is defined in advance with a minimum overlap length Y, which is the length over which the main body 32 and the adjuster 34 should be overlapped during construction. In the present embodiment, a minimum overlap length Y of about 100 mm is set by various experiments. The adjuster 34 of the present embodiment is provided with a mark 36 that appears so as to be visible when the overlap length Ya between the adjuster 34 and the main body 32 is less than the minimum overlap length Y.

The mark 36 is, for example, an opening. In this embodiment, each external corner corner 37 and the side wall portion 34a and the main wall portion 34b of the adjuster 34 meet each one landmark 36 is provided. Since such a mark 36 is formed across two surfaces in each corner corner 37, visibility from the operator is good during construction. In addition, since such a mark 36 can be formed simultaneously with the molding of the adjuster 34, it is excellent in productivity as compared with a ruled line or the like. Further, since the above-mentioned corner corner 37 is not usually a position where a screw is passed when fixing the face material 9, the mark 36 does not prevent the face material 9 from being fixed.

  The construction method of the wall 1c behind the hut out of the wall 1 configured as described above will be described. First, the upper runner 7 having an inclination along the roof slope and the lower runner 5 extending horizontally below the upper runner 7 are fixed. These steps are appropriately performed using mounting hardware or the like. Further, as described above, the upper runner 7 and the lower runner 5 are arranged with the groove portions facing each other.

  Next, a plurality of studs 8 extending vertically are arranged between the upper runner 7 and the lower runner 5. At this time, the variable length stud 30 whose length is adjustable is used for part or all of the stud 8.

  The variable-length stud 30 is preferably preliminarily adjusted to a length slightly smaller than the vertical dimension of the built-in position, in which the main body 32 and the adjuster 34 are inserted in advance. Then, the operator inserts and positions the main body portion 32 of the variable-length stud 30 whose length is adjusted into the groove portion of the upper runner 7, and then slides the adjuster 34 with respect to the main body portion 32 to extend it. The adjuster 34 is inserted into the groove portion of the lower runner 5. The variable length stud 30 is held in a so-called stretched state between the upper runner 7 and the lower runner 5.

The variable length stud 30 is built so that the pair of side wall portions 34 a of the adjuster 34 is parallel to the flange 18 of the lower runner 5. Accordingly, the adjuster 34, Switching Operation-out portion 22 is disposed in the wall core side of Sakaikabe 1c.

  In such a process, the operator can perform construction from around the roof beam 13 without climbing to a high position such as the back of the ceiling. Therefore, it is excellent in workability. In the present embodiment, the adjuster 34 is provided with a mark 36 that appears so as to be visible when the overlap length with the main body portion 32 is less than the minimum overlap length. Can be judged. In order to increase the stability, the lower end of the adjuster 34 may be temporarily fixed to the flange of the lower runner 5 with a one-touch screw or the like as necessary.

As shown in FIG. 9, the variable length stud 30 includes a plurality of types of main body portions 32 and adjusters 34 having different lengths in the boundary wall 1 c of the shed. FIG. 9 includes at least five types of lengths (a) to (e) for the main body 32. Further, the adjuster 34 includes two types indicated by symbols (S) and (L). By combining these, it is possible to cope with a change in the length in the vertical direction between the lower runner 5 and the upper runner 7. For example, for adjacent variable length studs 30 (b), the body portions 32 are identical to each other, but one has an S type adjuster 34 and the other has an L type adjuster 34 that is longer than the S type. Is used. As described above, the variable length stud 30 of the present embodiment can flexibly cope with different lengths by sharing the main body portion 32 and changing the length of the adjuster 34 (or vice versa). .

  Next, the face material 9 is fixed to both sides of the frame base composed of the lower runner 5, the upper runner 7 and the stud 8.

  In this step, for example, as shown in FIG. 5, the face material 9 is fixed to the variable length stud 30 with a plurality of screws 40. When the face material 9 is fixed to the variable length stud 30, the screw 40 is driven from the outer surface side of the face material 9 toward the variable length stud 30. The screw 40 is driven in including a first position P1 that first penetrates the side wall 34a of the adjuster 34 and a second position P2 that first penetrates the short side 32b of the main body 32.

  Here, when the screw 40 is first driven into the second position P2, the screw 40 can easily penetrate the short side portion 32b of the main body portion 32 having high rigidity, but the side wall portion 34a of the adjuster 34 is By the contact with the tip of the screw 40, the notch 22 is elastically deformed so as to narrow and escape. For this reason, the screw 40 penetrating the main body portion 32 licks the side wall portion 34a, and there is a possibility that sufficient screw fixing cannot be performed. For this reason, in this step, the screw 40 is driven earlier than the main body portion 32 toward the adjuster 34.

  At this time, as apparent from FIG. 5, the operator pulls the return portion 34 c or the side wall portion 34 a of the adjuster 34 toward the flange 18 side of the lower runner 5 with fingers, and the screw 40 is in the first position P <b> 1. It is particularly desirable to be driven into. As a result, the screw 40 can be reliably driven into the adjuster 34 of the variable length stud 30. Further, after the screw 40 is driven into the first position P1, the side wall portion 34a of the adjuster 34 is already fixed to the flange 18 side of the lower runner 5 even when the screw 40 is driven into the second position P2. The screw is not licked.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention can be deform | transformed and implemented in a various aspect. For example, the shape of the non-horizontal upper edge portion of the partition wall may include a stepped shape as well as a gradient shape.
