The upper and lower runners 3a and 3b extend in the predetermined direction at the upper and lower ends of the partition wall 1 and function as lateral (width direction) frames extending at the upper and lower ends of the partition wall 1. As shown in FIG. The upper runner 3a is fixed to the lower surface of the upper frame 2a with the groove 8a open downward, and extends in the predetermined direction along the lower surface of the upper frame 2a. The lower runner 3b is fixed to the upper surface of the lower frame 2b with the groove 8b open upward, and extends in the predetermined direction along the upper surface of the lower frame 2b. In this embodiment, the upper and lower runners 3a, 3b are arranged substantially parallel to each other. Note that the upper and lower runners 3a and 3b need only extend in the width direction of the partition wall 1 (predetermined direction), and need not be substantially parallel to each other.

As shown in FIGS. 1 to 3, the upper and lower runners 3a and 3b are integrally formed by a plate-shaped web 5 crossing the vertical direction and a pair of plate-shaped flanges 6a and 6b bent from both ends of the web 5. have Since the upper and lower runners 3a and 3b are vertically symmetrical and have substantially the same configuration, the upper runner 3a will be described below, and the description of the lower runner 3b will be omitted.

The upper runner 3a is formed to have a C-shaped cross section that is open downward and elongates in a predetermined direction. The web 5 elongates in a predetermined direction along the lower surface of the upper frame 2a and is fixed to the upper frame 2a. One flange 6a of the pair of flanges 6a and 6b (flange 6a on the front side (front side) in FIG. 1) bends from the front end of the web 5 and extends downward. An angle θ1 between one flange 6a and the web 5 is set at a substantially right angle (90 degrees). Of the pair of flanges 6a and 6b, the other flange 6b (back side (back side) flange 6b in FIG. 1) bends from the back side end of the web 5 and extends downward. An angle θ2 between the other flange 6b and the web 5 is set smaller than 90 degrees. The other flange 6b is formed longer downward than the one flange 6a. 2 shows a state in which the angle .theta.2 between the other flange 6b and the web 5 is widened by the stud 4 inserted into the groove 8a of the upper runner 3a.

One flange 6a of the upper runner 3a is formed with a plurality of openings 7 spaced apart from each other in the predetermined direction. A plurality of openings 7 of one flange 6a are formed in the shape of elongated long holes in the vertical direction. A plurality of openings 7 of one flange 6a are arranged at regular intervals in the predetermined direction. A distance (spaced distance) L1 between the plurality of openings 7 in the predetermined direction is set shorter than the length L2 (width L2) of the stud 4 in the predetermined direction. In this embodiment, the distance L1 between the plurality of openings 7 is set shorter than half the width L2 of the stud 4 .

As shown in FIGS. 1 and 3, the plurality of studs 4 are long members made of light iron (lightweight steel frame material) having a C-shaped cross section or a rectangular tubular shape. It extends in the vertical direction and functions as a vertical (vertical) framework extending between the upper and lower runners 3a and 3b of the partition wall 1. As shown in FIG. In this embodiment, the vertical length of the plurality of studs 4 is set shorter than the vertical linear distance between the web 5 of the upper runner 3a and the web 5 of the lower runner 3b. The upper end portions (supported portions) 4a of the plurality of studs 4 are inserted into the grooves 8a of the upper runner 3a and fixed to the upper runner 3a. The lower end portions (supported portions) 4b (see FIG. 4A) of the plurality of studs 4 are inserted into the grooves 8b of the lower runner 3b and fixed to the lower runner 3b. That is, the plurality of studs 4 have upper and lower supported portions (upper end 4a and lower end 4b) fixed to the upper and lower runners 3a and 3b. In this embodiment, the length L3 of the plurality of studs 4 in the depth direction (the direction intersecting both the vertical direction and the width direction) is the length in the depth direction of the webs 5 of the upper and lower runners 3a and 3b on the groove 8a side. Slightly shorter than L4 (see FIG. 2) and longer than the length in the depth direction between the tips of the pair of flanges 6a and 6b when the studs 4 are not inserted into the grooves 8a and 8b of the upper and lower runners 3a and 3b is set slightly longer. When inserting the upper end portions 4a and the lower end portions 4b of the plurality of studs 4 into the grooves 8a and 8b of the upper and lower runners 3a and 3b, the other flanges 6b of the upper and lower runners 3a and 3b are elastically deformed so as to expand further. and insert the upper end portions 4a and lower end portions 4b of the plurality of studs 4 into the grooves 8a and 8b of the upper and lower runners 3a and 3b. The upper end portions 4a and lower end portions 4b of the plurality of studs 4 are held by the upper and lower runners 3a and 3b by the elastic force of the other flanges 6b of the upper and lower runners 3a and 3b. With the upper end 4a and the lower end 4b of the stud 4 inserted into the grooves 8a and 8b of the upper and lower runners 3a and 3b, the lower end of the stud 4 abuts on the upper surface of the web 5 of the lower runner 3b. is spaced downward from the lower surface of the web 5 of the upper runner 3a. That is, a gap 10 is provided between the upper end of the stud 4 and the web 5 of the upper runner 3a. A vertical length L5 of the gap 10 between the upper end of the stud 4 and the web 5 of the upper runner 3a is set to a length that allows the stud 4 to tilt with respect to the upper and lower runners 3a and 3b, which will be described later. In addition, the shape of the plurality of studs 4 is not limited to the C-shaped cross section or the rectangular cylindrical shape, and may be other shapes. Further, the shapes of the plurality of studs 4 do not have to all be unified into the same shape, and studs 4 of different shapes may be mixed.

The upper end portions 4a and the lower end portions 4b of the plurality of studs 4 are inserted into the grooves 8a and 8b of the upper and lower runners 3a and 3b, respectively. , screws 9). Since the fixing manner of the upper end portion 4a of the stud 4 to the upper runner 3a and the fixing manner of the lower end portion 4b of the stud 4 to the lower runner 3b are substantially the same, the stud 4 is fixed to the upper runner 3a. A manner of fixing the upper end portion 4a will be explained, and a description of a manner of fixing the lower end portion 4b of the stud 4 to the lower runner 3b will be omitted.

As shown in FIG. 3, the upper end 4a of the stud 4 is fastened and fixed to one flange 6a of the upper runner 3a with a screw 9 while being inserted into the groove 8a of the upper runner 3a. When fixing the upper end portion 4a of the stud 4 to one flange 6a of the upper runner 3a, among the plurality of openings 7 of the one flange 6a, the surface of the upper end portion 4a of the stud 4 to be fixed is fixed. The screw 9 is inserted into the opening 7a facing the stud 4, and the screw 9 is pressed and tightened while the tip of the screw 9 is in contact with the surface 11 on the front side of the upper end portion 4a of the stud 4. Thereby, the upper end portion 4a of the stud 4 is fixed to one flange 6a of the upper runner 3a. The position where the screw 9 is inserted in the opening 7a of one flange 6a is preferably an intermediate position excluding the upper and lower ends of the opening 7a. That is, in a state where the upper end portion 4a of the stud 4 is fastened and fixed to one flange 6a of the upper runner 3a with the screw 9, there is a surplus area of the opening 7a both above and below the screw 9. is preferred.

After a plurality of studs 4 are fixed to the upper and lower runners 3a, 3b and the frame of the partition wall 1 is formed by the upper and lower runners 3a, 3b and the plurality of studs 4, the plurality of studs 4 and the upper and lower runners 3a, 3b are formed. A gypsum board (not shown) is fixed to at least one of the surface on the near side and the surface on the far side of the .

In the partition wall 1 configured as described above, the upper and lower skeletons 2a and 2b are relatively displaced vertically and horizontally during vibration such as an earthquake, and accordingly the upper and lower runners 3a and 3b move vertically and horizontally. , the stud 4 can follow the upper and lower runners 3a, 3b.

4A and 4B are explanatory diagrams showing the relative displacement of the upper and lower skeletons 2a and 2b, in which (a) shows the state before displacement and (b) shows the state after displacement.

As shown in FIG. 4, when the upper and lower skeletons 2a and 2b are relatively displaced in the horizontal direction from the normal state (see FIG. 4(a)), the upper and lower runners 3a and 3b are moved in the horizontal direction. (see FIG. 4(b)). Since the openings 7a of the upper and lower runners 3a and 3b are elongated holes in the vertical direction, the upper and lower runners 3a and 3b are relatively displaced to the left and right so that the openings 7a of the upper runners 3a and the lower When the linear distance between the runner 3b and the opening 7a changes, the screw 9 fixing the stud 4 can be vertically moved (slid) within the opening 7a of the upper and lower runners 3a, 3b. Therefore, when the upper and lower skeletons 2a and 2b are relatively displaced in the horizontal direction, the movement of the screws 9 within the openings 7a of the upper and lower runners 3a and 3b causes the gap between the openings 7a of the upper and lower runners 3a and 3b to move. Since the change in distance can be absorbed, the input of force to the stud 4 from the upper and lower runners 3a and 3b can be suppressed, and the deformation of the stud 4 can be suppressed. In this manner, deformation of the studs 4 can be suppressed when the upper and lower skeletons 2a and 2b are relatively displaced in the horizontal direction, so damage to the partition wall 1 can be suppressed.

Similarly to the case where the upper and lower skeletons 2a and 2b are relatively displaced in the horizontal direction, the upper and lower skeletons 2a and 2b are relatively displaced in the vertical direction, and the opening 7a of the upper runner 3a and the lower runner Even if the linear distance between the openings 7a of the upper and lower runners 3a, 3b changes, the change in the distance between the openings 7a of the upper and lower runners 3a, 3b is absorbed by the movement of the screws 9 within the openings 7a of the upper and lower runners 3a, 3b. Therefore, the force input from the upper and lower runners 3a and 3b to the stud 4 can be suppressed, and the deformation of the stud 4 can be suppressed. Therefore, when the upper and lower skeletons 2a and 2b are relatively displaced in the vertical direction, deformation of the studs 4 can be suppressed, so damage to the partition wall 1 can be suppressed.

Further, since a gap 10 is provided between the upper end of the stud 4 and the web 5 of the upper runner 3a, the upper and lower runners 3a and 3b are relatively displaced to the left and right, so that the stud 4 is displaced from the upper and lower runners 3a. , 3b, contact between the upper end of the stud 4 and the web 5 of the upper runner 3a can be suppressed. Therefore, when the upper and lower skeletons 2a and 2b are displaced relative to each other in the left-right direction, the upper end of the stud 4 and the web 5 of the upper runner 3a come into contact with each other, causing the upper and lower runners 3a and 3b to contact the stud 4. Since input of force can be suppressed and deformation of the stud 4 can be prevented, damage to the partition wall 1 can be suppressed.

Thus, according to this embodiment, it is possible to suppress damage to the partition wall 1 when the upper and lower skeletons 2a and 2b are relatively displaced.

Further, the distance L1 between the plurality of openings 7 of one flange 6a of the upper and lower runners 3a and 3b in the predetermined direction is set shorter than the length L2 of the stud 4 in the predetermined direction. Therefore, even if the stud 4 is arranged at any position of the upper and lower runners 3a and 3b in the predetermined direction, at least one of the plurality of openings 7 faces the surface 11 on the front side of the upper end portion 4a of the stud 4. can be made Therefore, the stud 4 and the upper and lower runners 3a and 3b can be fixed by the screws 9 passing through the openings 7 regardless of the position of the stud 4 in the predetermined direction of the upper and lower runners 3a and 3b.

In this embodiment, one flange 6a of the upper and lower runners 3a and 3b is provided with the opening 7, but the present invention is not limited to this. Openings 7 may be provided in 6b or both flanges 6a, 6b may be provided with openings 7. FIG. That is, it is sufficient that at least one flange of the pair of flanges 6a and 6b is provided with the opening 7. As shown in FIG.

In addition, although the openings 7 are provided in both the upper and lower runners 3a and 3b in this embodiment, the openings 7 may be provided only in one of the upper and lower runners 3a and 3b. That is, the opening 7 may be provided in at least one runner of the upper and lower runners 3a and 3b. For example, the opening 7 may be provided only in the upper runner 3a, and the opening 7 may not be provided in the lower runner 3b. In this case, one flange 6a of the lower runner 3b without the opening 7 and the lower end portion 4b of the stud 4 may be fixed with a screw (rod-shaped fixing member) 9. FIG.

Further, in the present embodiment, there are openings 7 (openings 7 between studs 4) that are not used as openings 7a for inserting screws 9 in a state where a plurality of studs 4 are fixed to upper and lower runners 3a and 3b (Fig. 1), but it is not limited to this, and only the openings 7a used as the openings 7a through which the screws 9 are inserted may be provided in the upper and lower runners 3a and 3b. That is, in the present embodiment, the distance L1 between the plurality of openings 7 in the predetermined direction is set shorter than the length L2 of the stud 4 in the predetermined direction. The distance L1 between the openings 7 in the predetermined direction may be set longer than the length L2 of the stud 4 in the predetermined direction.

Further, in this embodiment, the lower end of the stud 4 is brought into contact with the upper surface of the web 5 of the lower runner 3b, but the present invention is not limited to this. It may be spaced upwards to provide a gap between the lower end of the stud 4 and the web 5 of the lower runner 3b. In this case, the upper end of the stud 4 may be brought into contact with the web 5 of the upper runner 3a, or the upper end of the stud 4 may be spaced downward from the lower surface of the web 5 of the upper runner 3a.

In this embodiment, the length of the stud 4 in the vertical direction is set shorter than the vertical linear distance between the web 5 of the upper runner 3a and the web 5 of the lower runner 3b. and the web 5 of the upper runner 3a, the gap 10 is provided, but it is not limited to this. For example, the vertical length of the stud 4 is set to be substantially the same as the vertical linear distance between the web 5 of the upper runner 3a and the web 5 of the lower runner 3b, and the upper and lower ends of the stud 4 are It may be brought into contact with the webs 5 of the upper and lower runners 3a, 3b. Even in this case, deformation of the studs 4 can be suppressed at least when the upper and lower skeletons 2a and 2b are relatively displaced in the vertical direction, so damage to the partition wall 1 can be suppressed.

Further, in this embodiment, the length L3 of the stud 4 in the depth direction is defined as the distance between the tips of the pair of flanges 6a and 6b when the stud 4 is not inserted into the grooves 8a and 8b of the upper and lower runners 3a and 3b. Although it is set slightly longer than the length in the depth direction, it is not limited to this. For example, the length L3 of the stud 4 in the depth direction is less than the length in the depth direction between the tips of the pair of flanges 6a and 6b when the stud 4 is not inserted into the grooves 8a and 8b of the upper and lower runners 3a and 3b. can also be set shorter. In this case, the upper end portion 4a and the lower end portion 4b of the stud 4 are inserted into the grooves 8a and 8b of the upper and lower runners 3a and 3b, and the upper end portion 4a and the lower end portion 4b of the stud 4 are brought into contact with one of the flanges 6a.
