Description

[Technical Field]

[0001] The present invention relates to a partition wall structure that divides rooms in a building. [Background technology]

[0002] When constructing partition walls within a building, studs extending in the vertical direction are installed at multiple intervals between runners installed above and below the building in order to secure the wall materials.

[0003] An example of a partition wall structure is disclosed in Patent Document 1. In the wall structure disclosed in Patent Document 1, runners 3 with a U-shaped cross section are provided facing each other on a floor board section 1 and a ceiling section 2, and multiple studs 4 with stud spacers 9 attached are fitted into the facing runners 3 in the direction in which they extend.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-170296 Summary of the Invention [Problem to be solved by the invention]

[0005] In the structure described in Patent Document 1, stud spacers 9 are attached to both ends of the stud 4, and then the stud 4 is slid relative to the runner 3, which is inefficient to work on the construction site.

[0006] The present invention has been made in view of the above-mentioned circumstances, and has as its object to provide a partition wall structure that is easy to work with at a construction site. [Means for solving the problem]

[0007] (1) A partition wall structure according to the present invention comprises a pair of flat runners positioned apart in the vertical direction and each extending along a first direction, positioning members positioned at an interval in the first direction and extending in the vertical direction from each of the pair of runners, a plurality of studs positioned by the positioning members in either the first direction or a second direction perpendicular to the first direction and positioned at an interval in the first direction, and a pair of wall members each extending along the first direction and supported by the studs. The studs are slidable relative to the positioning members in the other of the second directions in which they are not positioned.

[0008] With this configuration, the worker assembling the partition wall can slide the stud in the second direction between the pair of flat runners to attach it to the positioning member, making installation easy. Also, there is no need to adjust the installation position of the stud relative to the runner on site.

[0009] (2) Preferably, one of the pair of wall materials is supported by some of the studs, and the other of the pair of wall materials is supported by the stud that does not support the one wall material.

[0010] According to the above configuration, since a pair of wall materials are not both supported by the same stud, sound is less likely to propagate through the studs in the partition wall.

[0011] (3) Preferably, the pair of wall materials are spaced apart from the unsupported stud in the second direction.

[0012] According to the above configuration, the wall material is spaced apart from the studs that do not support the wall material, so sound is less likely to propagate through the partition wall.

[0013] (4) Preferably, the dimension of the pair of runners along the second direction is smaller than the dimension of the stud along the second direction.

[0014] According to the above configuration, the pair of wall materials do not abut against the runners, so sound is less likely to propagate through the runners in the partition wall.

[0015] (5) Preferably, the positioning members are a pair of flat plate-shaped members spaced apart in the first direction and extending along the second direction, the studs have protrusions that protrude in the first direction, and the studs are positioned in the first direction by being sandwiched between the positioning members, and are positioned in one direction in the second direction by the protrusions and the positioning members abutting in the second direction.

[0016] According to the above configuration, when the stud is slid and attached to a pair of flat positioning members extending along the second direction, the worker can easily position the stud in the second direction by abutting the protruding portion of the stud protruding in the first direction against the positioning members.

[0017] (6) Preferably, the pair of runners have support portions extending along the second direction and supporting the wall material.

[0018] According to the above configuration, the wall material is installed in a more stable state. [Effects of the Invention]

[0019] According to the present invention, the partition wall can be easily assembled. [Brief explanation of the drawings]

[0021] Hereinafter, an embodiment of the present invention will be described. The embodiment described below is merely an example of the present invention, and it goes without saying that the embodiment of the present invention can be appropriately modified without departing from the spirit and scope of the present invention.

[0022] In this embodiment, the up-down directions 1 and 2 are vertical directions, with the direction from the floor to the ceiling being upward 1 and the opposite direction being downward 2. The front-to-back directions 3 and 4 (an example of a first direction) are directions along the floor and ceiling surfaces of a building, with any direction along the floor and ceiling surfaces being forward 3 and the opposite direction being backward 4. The left-to-right directions 5 and 6 (an example of a second direction) are directions perpendicular to the up-to-down directions 1 and 2 and the front-to-back directions 3 and 4, with the direction in which the stud 17 is inserted into the positioning member 16B being leftward 5 and the opposite direction being rightward 6.

[0023] A partition wall 10 (an example of a partition wall structure) is a wall that divides a single space in a building into multiple spaces. As shown in Figure 1, the partition wall 10 is continuous with the floor and ceiling and extends along vertical directions 1, 2 and front-to-back directions 3, 4.

[0024] The partition wall 10 includes an upper runner 15U, a lower runner 15L, a plurality of studs 17, and a wall material 18. Note that in each drawing, the lengths of the upper runner 15U, the lower runner 15L, the studs 17, and the wall material 18 in the up-down directions 1 and 2 and the front-to-back directions 3 and 4 are partially omitted, and the number of studs 17 in the front-to-back directions 3 and 4 is also omitted.

[0025] The upper runner 15U is fixed to the ceiling of the building. The lower runner 15L is fixed to the floor of the building. As a result, as shown in Figure 2, the upper runner 15U and the lower runner 15L are positioned apart in the vertical direction 1, 2. The upper runner 15U and the lower runner 15L have the same shape except for the position of the end face 32 (described later) except for their different arrangements, so the shape of the lower runner 15L will be explained as an example.

[0026] As shown in FIG. 2, the lower runner 15L has a base portion 16A, a positioning member 16B, and a support portion 16C.

[0027] The base 16A has a flat plate shape that is elongated in the front-to-rear directions 3, 4. The dimensions of the base 16A in the left-to-right directions 5, 6 are smaller than the dimensions of the stud 17 in the left-to-right directions 5, 6. The dimensions of the base 16A in the left-to-right directions 5, 6 are constant in the front-to-rear directions 3, 4. The base 16A abuts against the lower end surface of the stud 17 (the upper end surface of the stud 17 in the upper runner 15U).

[0028] The positioning member 16B is fixed by welding to the upper surface of the base 16A (or to the lower surface of the base 16A in the upper runner 16U). The positioning member 16B determines the position of the stud 17 in the front-rear directions 3, 4 and the left-right directions 5, 6. As shown in FIGS. 2 and 3, the positioning member 16B is a U-shaped member that opens upward 1 and in the left-right directions 5, 6, and is formed by bending a flat plate-shaped member. The positioning member 16B has two upright pieces 35 that are spaced apart and facing each other in the front-rear directions 3, 4, and a connecting portion 36 that connects the two upright pieces 35. The dimensions of the positioning member 16B in the left-right directions 5, 6 are approximately the same as the dimensions of the base 16A in the left-right directions 5, 6. The connection portion 36 is fixed to the base 16A so that the connection portion 36 overlaps the upper surface of the base 16A (the lower surface of the base 16A in the case of the upper runner 16U) and the left and right ends of the base 16A are aligned with the left and right ends of the positioning member 16B.

[0029] The upright pieces 35 each protrude upward 1 from the base 16A, and each main surface extends in the up-down directions 1, 2 and the left-right directions 5, 6. The distance between the two upright pieces 35 in the front-to-rear directions 3, 4 is slightly smaller than the dimension of the stud 17 in the front-to-rear directions 3, 4. As will be described later, the recess 30 of the stud 17 can be inserted between the two upright pieces 35. The stud 17 is positioned in the front-to-rear directions 3, 4 by being sandwiched between the two upright pieces 35 in the recess 30.

[0030] A plurality of the positioning members 16B described above are arranged at intervals on the base 16A in the front-rear directions 3 and 4. The arrangement of the positioning members 16B is not particularly limited, but in this embodiment, it is ½ of the dimension of the wall material 18 in the front-rear directions 3 and 4.

[0031] The support portion 16C supports the wall material 18 together with the studs 17. The support portion 16C is fixed by welding to the upper surface of the base portion 16A of the lower runner 15L (to the lower surface of the base portion 16A of the upper runner 15U). The support portion 16C is disposed between adjacent positioning members 16B. The support portion 16C has a plate-shaped portion 25 and a fixing portion 26.

[0032] The plate-like portion 25 is a flat plate-shaped member extending in the left-right directions 5 and 6 .

[0033] The wall material 18 is fixed to the fixing portion 26. The fixing portion 26 is supported by the plate-like portion 25 and extends along the rear surface of the wall material 18. The wall material 18 is fixed to the fixing portion 26 with screws (not shown) or the like.

[0034] 1 and 2, the studs 17 are rectangular columns extending in the up-down directions 1 and 2. A plurality of studs 17 are arranged at intervals in the front-to-rear directions 3 and 4, with their upper and lower end faces abutting the upper runner 15U and the lower runner 15L, respectively. The dimensions of the studs 17 in the left-to-right directions 5 and 6 are larger than the dimensions of the bases 16A of the upper runner 15U and the lower runner 15L in the left-to-right directions 5 and 6.

[0035] 4 and 5, the stud 17 has recesses 30 at the upper and lower ends of two side surfaces 31 (an example of a protrusion) extending in the vertical directions 1 and 2 and the horizontal directions 5 and 6. In other words, one stud 17 has four recesses 30 formed therein.

[0036] As shown in FIG. 4, the recesses 30 are positioned at the upper and lower ends of the side surface 31, offset to one side in the left-right directions 5, 6. The recesses 30 are recessed from the side surface 31 in the front-rear directions 3, 4, and open only to one side in the left-right directions 5, 6. As shown in FIGS. 4 and 5, all four recesses 30 open to the left in the left-right directions 5, 6, and none open to the right 6. Therefore, in the four recesses 30, the end faces 32 are positioned to the right 6. The position of the end faces 32 of each of the four recesses 30 in the left-right directions 5, 6 is the same, and they are to the right of the center of the side surface 31 in the left-right directions 5, 6.

[0037] Two recesses 30 located at the upper or lower end of the stud 17 and spaced apart in the front-to-rear directions 3, 4 can be inserted between two standing pieces 35 of the positioning member 16B. By sandwiching the recesses 30 between the standing pieces 35, the stud 17 is positioned in the front-to-rear directions 3, 4. As shown in Figure 4, in an orientation in which the two recesses 30 open to the left 5, the stud 17 is slid to the left 5, and the standing pieces 35 enter the two recesses 30, respectively.

[0038] The distance between the two side surfaces 31 of the stud 17 that are separated in the front-rear direction 3, 4 is greater than the distance between the two upright pieces 35 of the positioning member 16B in the front-rear direction 3, 4. Therefore, the portion of the stud 17 other than the recesses 30 cannot be inserted between the two upright pieces 35. Therefore, as shown in FIG. 4 , if the two recesses 30 are oriented so that they open to the left 5, the stud 17 is slid leftward 5, and the upright pieces 35 that enter the two recesses 30 respectively abut against the end surfaces 32 of the recesses 30. The abutment of the upright pieces 35 against the end surfaces 32 positions the stud 17 in one of the left-right directions 5, 6. In the orientation of the stud 17 shown in FIG. 4 , the stud 17 is positioned in the leftward direction 5. In this state, the stud 17 is fixed to the upright pieces 35 with screws or the like (not shown).

[0039] As shown in FIG. 6 , the multiple studs 17 in this embodiment include a first stud 17A having an end face 32 located to the right of the center of the side surface 31 in the left-right directions 5, 6, and a second stud 17B having an end face 32 to the right of the first stud 17A in the left-right directions 5, 6. That is, the dimension by which the second stud 17B protrudes from the base 16A in the left-right directions 5, 6 is greater than the dimension by which the first stud 17A protrudes from the base 16A in the left-right directions 5, 6. As shown in FIGS. 2 and 8 , the first stud 17A and the second stud 17B are oriented such that the recesses 30 open to the left in the left-right directions 5, 6. That is, the first stud 17A and the second stud 17B are offset from the center of the base 16A in the left-right directions 5, 6.

[0040] 1, wall material 18 is a rectangular board that serves as a wall base material. Wall material 18 is located on both sides of first stud 17A and second stud 17B in the left-right directions 5 and 6, and is fixed in place with screws or the like. First stud 17A and second stud 17B protrude from bases 16A of upper runner 15U and lower runner 15L in the left-right directions 5 and 6, so wall material 18 does not come into contact with bases 16A.

[0041] As shown in FIG. 6 , the wall member 18 is fixed to the stud 17, which protrudes significantly from the base 16A in one of the left-right directions 5 and 6. As described above, the first stud 17A and the second stud 17B are offset from the center of the base 16A in the left-right directions 5 and 6, respectively, so that one of the studs protrudes significantly more in one of the left-right directions 5 and 6 than the other. When the first stud 17A and the second stud 17B are in the position shown in FIG. 4 , the first stud 17A protrudes significantly to the left 5, and the second stud 17B protrudes significantly to the right 6. Furthermore, the first stud 17A and the second stud 17B shown in FIG. 6 are positioned relative to the left 5 by the positioning member 16B. The wall member 18 is located to the left of the first stud 17A and secured by a screw or the like, and is located to the right of the second stud 17B and secured by a screw or the like. Each wall member 18 extends in the up-down directions 1 and 2 and the front-rear directions 3 and 4. Furthermore, the dimension by which the first stud 17A protrudes from the base 16A in the leftward direction 5 is smaller than the dimension by which it protrudes in the rightward direction 6. The dimension by which the second stud 17B protrudes from the base 16A in the rightward direction 6 is smaller than the dimension by which it protrudes in the leftward direction 5. Because the dimensions of each stud 17A, 17B in the left-right directions 5, 6 are the same, the first stud 17A does not abut the wall material 18 fixed to the second stud 17B, and the second stud 17B does not abut the wall material 18 fixed to the first stud 17A. In other words, there is a gap S1 between the first stud 17A and the wall material 18 fixed to the second stud 17B in the left-right directions 5, 6, and there is also a gap S2 between the second stud 17B and the wall material 18 fixed to the first stud 17A in the left-right directions 5, 6. In other words, the pair of wall materials 18 are spaced apart from the unsupported stud 17 in the left-right directions 5, 6. One wall material 18 is fixed at both ends in the front-rear directions 3, 4 to two adjacent first studs 17A or two adjacent second studs 17B with screws (not shown) or the like.

[0042] [Partition wall 10 construction method] The construction method by which workers assemble the partition wall 10 will be described below.

[0043] When assembling the partition wall 10, a worker fixes the upper runner 15U to the ceiling surface with screws or the like, and fixes the lower runner 15L to the floor surface with screws or the like.

[0044] Next, the worker inserts the studs 17 between the two upright pieces 35 of the positioning member 16B by sliding them in the left-right directions 5, 6. The multiple studs 17 are each inserted in the leftward direction 5. The positioning member 16B positions each stud 17 in the front-rear directions 3, 4 and also in one of the left-right directions 5, 6. In other words, each stud 17 can slide in the rightward direction 6, in which it is not positioned, of the left-right directions 5, 6. The studs 17 are fixed to the upper runner 15U and the lower runner 15L with screws or the like.

[0045] The worker fixes the wall materials 18 to the studs 17 that have been positioned in the front-to-rear directions 3, 4 and one of the left-to-right directions 5, 6 by the positioning members 16B. The wall materials 18 located on both sides of the left-to-right directions 5, 6 are not fixed to the same studs 17, but are fixed to studs 17 that protrude further in one of the left-to-right directions 5, 6 from the bases 16A of the upper runner 15U and the lower runner 15L. Although not shown in the drawings, the wall materials 18 are provided with decorative materials such as wall cloth.

[0046] [Effects of this embodiment] Because the pair of runners 15U, 15L are flat, the movement of the studs 17 in the left-right directions 5, 6 is not obstructed by the pair of runners 15U, 15L. This allows the worker assembling the partition wall 10 to easily attach the studs 17 to the positioning member 16B by sliding the studs 17 between the pair of runners 15U, 15L in the left-right directions 5, 6. Furthermore, because the studs 17 can be attached directly to the positioning member 16B without having to be slid relative to the pair of runners 15U, 15L in the front-rear directions 3, 4, there is no need to adjust the attachment positions of the studs 17 relative to the pair of runners 15U, 15L on-site.

[0047] One wall material 18 is supported by a first stud 17A, and the other wall material 18 is supported by a second stud 17B. This allows a space to be formed between one wall material 18 and the second stud 17B or between the other wall material 18 and the first stud 17A, preventing one wall material 18 and the other wall material 18 from connecting to each other.

[0048] Since a space is formed between the wall materials 18 arranged on the left and right sides and spaced apart from the studs 17, sound does not propagate directly through the studs 17 between the wall materials 18.

[0049] Since the wall material 18 is arranged so as not to abut against the pair of runners 15U, 15L, sound does not propagate directly through the runners 15U, 15L between the wall materials 18 arranged on the left and right.

[0050] The studs 17 are attached by sliding them from the left and right directions 5 and 6 to the flat positioning members 16B arranged side by side in the front-to-rear directions 3 and 4, and the side surfaces 31 of the studs 17 located in the front-to-rear directions 3 and 4 abut against the positioning members 16B. This allows the worker to easily determine the position of the studs 17 in the left and right directions 5 and 6 relative to the pair of runners 15U and 15L.

[0051] The wall material 18 is supported by support portions 16C extending in the left-right directions 5 and 6 from a pair of runners 15U and 15L, and is fixed at multiple points in addition to the studs 17, allowing for a more stable installation.

[0052] [Variation 1] In the above embodiment, the protrusion is formed by the side surface 31 and the recess 30, but the present invention is not limited to this configuration.

[0053] For example, as shown in Fig. 7, the protrusion 42 may be formed to protrude in the front-rear directions 3, 4 from a surface 41 of the stud 40 in the front-rear directions 3, 4 (the protrusion 42 extending rearward 4 is omitted in Fig. 7). The protrusion 42 is located to the right of the center of the stud 40 in the left-right directions 5, 6, and positions the stud 40 in one direction in the left-right directions 5, 6 when the stud 40 is inserted into the positioning member 16B.

[0054] [Variation 2] 8, the protrusions 52 may cover the upright pieces 35 from the outside when the studs 50 are placed on the positioning member 16B (shown by the broken lines in the drawing).

[0055] Specifically, protrusion 52 protrudes in the front-rear directions 3 and 4 from a surface 51 of stud 17 in the front-rear directions 3 and 4. Protrusion 52 has a surface 53 extending in the up-down directions 1 and 2 and the left-right directions 5 and 6 on the outer side in the front-rear directions 3 and 4 of positioning member 16B disposed on stud 50. Protrusion 52 is connected to surface 51 on the left and upper sides and is open on the right and lower sides.

[0056] [Variation 3] In addition, in the above embodiment, an example was given in which the recess 30 is recessed from the side surface 31 in the front-to-rear directions 3, 4 and is open only in one of the left-to-right directions 5, 6, but this configuration is not limited to this.

[0057] 9, recess 61 may be recessed from side surface 62 in front-to-rear directions 3 and 4, and may not be open in both left-to-right directions 5 and 6. In other words, recess 61 may be open only toward the end of stud 60. After attaching lower runner 15L to stud 60 facing upward 1 and upper runner 15U to stud 60 facing downward 2, they are fixed to the floor and ceiling surfaces with screws (not shown).

[0058] [Other variations] Furthermore, although the example has been described in which the direction in which the pair of runners 15U, 15L of the partition wall 10 according to this embodiment extends is the front-to-rear directions 3, 4, the present invention is not limited to this configuration. The direction in which the pair of runners 15U, 15L extend may be the left-to-right directions 5, 6, or may be a horizontal direction other than the front-to-rear directions 3, 4 and the left-to-right directions 5, 6. In other words, the purpose is that the direction in which the pair of runners 15U, 15L extend may be a horizontal direction.

[0059] In addition, although the positioning members 16B and support portions 16C of the partition wall 10 according to this embodiment have been described as being fixed to the upper runner 15U and the lower runner 15L by welding, this is not the only method. The positioning members 16B and support portions 16C may be glued to the upper runner 15U and the lower runner 15L, or may be fixed with bolts and nuts.

[0060] Furthermore, although the upper runner 15U and lower runner 15L of the partition wall 10 according to this embodiment have been described as having the support portion 16C as an example, the upper runner 15U and lower runner 15L may not have the support portion 16C.

[0061] Furthermore, in this embodiment, the positioning member 16B is a separate member from the base 16A, but the positioning member 16B may be formed integrally with the base 16A, or may be formed by cutting and raising an upright piece 35 from the base 16A from a runner 15L that has been notched in advance into an H-shape or two opposing U-shapes.

[0062] Furthermore, the positioning member 16B of the partition wall 10 according to this embodiment is a U-shaped member that opens upward 1 and in the left-right directions 5 and 6, and has been described as being formed by bending a flat plate-shaped member, but is not limited to this configuration. The positioning member 16B may also be formed by combining two members with an L-shaped cross section into a U-shape.

[0063] Furthermore, in this embodiment, the end faces 32 of the first stud 17A and the second stud 17B of the multiple studs 17 of the partition wall 10 are positioned at different positions in the left-right directions 5, 6, and are inserted into the positioning member 16B from one of the left-right directions 5, 6, but this configuration is not limited to this.

[0064] All of the multiple studs 17 may have the same shape and be positioned at the same positions in the left-right directions 5, 6 on the end surface 32. In this case, the positions in the left-right directions 5, 6 on the end surface 32 are set so that the studs 17 arranged side by side in the front-rear directions 3, 4 are alternately shifted in the left-right directions 5, 6 from the pair of runners 15U, 15L. These multiple studs 17 are arranged on the pair of runners 15U, 15L with the left-right directions 5, 6 reversed. The multiple studs 17 are alternately arranged so that those that slide to the right 6 and those that slide to the left 5. As a result, the studs 17 positioned by the positioning member 16B protrude by different lengths in the left-right directions 5, 6 from the bases 16A of the upper runner 15U and the lower runner 15L. A gap exists in the left-right directions 5, 6 between the stud 17 inverted in the left-right directions 5, 6 and the wall material 18 fixed to the stud 17 in an uninverted position, and a gap also exists in the left-right directions 5, 6 between the stud 17 in an uninverted position and the stud 17 inverted in the left-right directions 5, 6.

[0065] Furthermore, for the sake of convenience, this embodiment has been described using two studs 17, a first stud 17A and a second stud 17B, but it goes without saying that the multiple studs 17 may be composed of three or more studs arranged in the front-to-rear directions 3, 4.

[0066] In addition, although the example has been described in which both ends of the studs 17 of the partition wall 10 in this embodiment are fixed to positioning members 16B arranged along the front-to-back directions 3, 4 of a pair of runners 15U, 15L, the studs 17 may be fixed to all of the arranged positioning members 16B, or may be arranged in a thinned-out state using some of the positioning members 16B.

[0067] Although the support portions 16C of the partition wall 10 according to this embodiment have been described as being fixed to the base portions 16A of the pair of runners 15U and 15L, this configuration is not limiting. For example, the support portions 16C may be integrally formed with the pair of runners 15U and 15L and extend in the left-right directions 5 and 6. The support portions 16C may also be disposed on only one of the pair of runners 15U and 15L. The support portions 16C may extend on only one of the pair of runners 15U and 15L, rather than on both sides of the pair of runners 15U and 15L in the left-right directions 5 and 6. Furthermore, the support portions 16C may be disposed at the same positions in the front-rear directions 3 and 4 on both sides of the pair of runners 15U and 15L in the left-right directions 5 and 6, or may be disposed so that the left and right support portions are offset from each other in the front-rear directions 3 and 4.

[0068] Furthermore, although the example has been described in which the wall material 18 of the partition wall 10 according to this embodiment is supported by studs 17 aligned in the front-to-rear directions 3 and 4 and alternately offset in the left-to-right directions 5 and 6, the present invention is not limited to this configuration. For example, the wall material 18 may be supported by studs 17 aligned irregularly in the front-to-rear directions 3 and 4 so as to be offset in the left-to-right directions 5 and 6.
