Description

[Technical Field]

[0001] The present disclosure relates to a partition wall structure and a clip. [Background technology]

[0002] Patent Document 1 describes a lightweight steel frame partition wall, which includes upper and lower runners fixed to the upper floor side (floor slab) and the lower floor side (floor slab), studs with their upper and lower ends inserted into the upper and lower runners, gypsum boards fixed to the studs, and glass wool filled in the hollow space surrounded by them.

[0003] [Patent Document 1] Patent No. 5585997 Summary of the Invention [Problem to be solved by the invention]

[0004] In a partition wall having upper and lower runners and a plurality of studs extending between the upper and lower runners, such as the lightweight steel partition wall described in Patent Document 1, it is necessary to ensure the strength of the partition wall by, for example, increasing the number of studs as the height of the partition wall increases. However, increasing the number of studs narrows the spacing between the studs (the widthwise distance of the partition wall), which may narrow the width of the space defined by the upper and lower runners and studs. For example, when installing insulation for the partition wall in the space defined by the upper and lower runners and studs, narrowing the spacing between the studs may make the process of installing the insulation more complicated.

[0005] Therefore, the present disclosure aims to provide a partition wall structure and clip that can ensure the strength of the partition wall and ensure a wide space in the width direction defined by the upper and lower runners and studs. [Means for solving the problem]

[0006] In order to solve the above problems, a first aspect of the present invention is a partition wall structure for a building, comprising upper and lower runners arranged at positions spaced apart from each other above and below and extending in a width direction that intersects the vertical direction, partition posts extending in the vertical direction between the upper and lower runners and supported by the upper and lower runners, and clips attached to the partition posts, wherein the partition posts have a pair of studs extending in the vertical direction, each of the pair of studs being formed with a C-shaped cross section having a plate-like web that intersects the width direction and a pair of flanges bending from both ends of the web, and the studs stand upright with the webs in contact with each other and back to back, and the clip has a middle portion extending in the width direction along the surfaces of the flanges on one side of the pair of studs, and a pair of locking portions provided on both ends of the middle portion in the width direction that lock the tips of the flanges on one side of the pair of studs, holding the pair of studs in the back-to-back state.

[0007] A second aspect of the present invention is a partition wall structure of the first aspect, comprising a board fixed to the studs and an insulating material arranged between the upper and lower runners, wherein a plurality of the studs are provided between the upper and lower runners so as to be spaced apart from each other in the width direction, the board is fixed across the plurality of studs, and the insulating material is fixed to the back surface of the board.

[0008] A third aspect of the present invention is a clip for holding a pair of studs extending in a predetermined direction, each stud having a web and a pair of flanges rising from both ends of the web, in a back-to-back state with the webs in contact with each other, the clip comprising: an intermediate portion extending in a direction intersecting the predetermined direction along the surface of the adjacent flange on one side of the pair of studs in the back-to-back state; and a pair of locking portions provided at both ends of the intermediate portion for locking the tip ends of the flange on one side of the pair of studs in the back-to-back state.

[0009] A fourth aspect of the present invention is the clip of the third aspect, wherein the intermediate portion is formed in a plate shape facing the surface of the flange on one side of the pair of studs in the back-to-back state. [Effects of the Invention]

[0010] According to the present disclosure, the strength of the partition wall can be ensured, and the space defined by the upper and lower runners and studs can be made wider in the width direction. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] An embodiment of the present invention will be described below with reference to the drawings. In each drawing, UP indicates the upper side, LF indicates the left side in the width direction of the partition wall 1, and FR indicates the front side (near side) in the wall thickness direction of the partition wall 1. In the following description, the left-right direction means the left-right direction when the partition wall is viewed from the front.

[0013] Fig. 1 is a schematic front view of a partition wall 1 according to one embodiment of the present invention. Fig. 2 is a cross-sectional view taken along the line II-II in Fig. 1. Fig. 3 is a perspective view of a clip attached to the rear side of a stud. Note that Fig. 1 shows only a portion of a gypsum board 6. Also, Fig. 1 does not show a heat insulating material 7.

[0014] As shown in FIG. 1, the partition wall structure according to this embodiment is applied to the structure of a partition wall 1 for dividing the interior space of a building.

[0015] The partition wall 1 comprises upper and lower runners 3a, 3b, a plurality of studs 4 standing between the upper and lower runners 3a, 3b, clips 30 (see Figure 2) attached to the studs 4, anti-vibration members 5, gypsum boards (boards) 6 fixed to the studs 4, and heat insulating material 7 (see Figure 2).

[0016] The upper and lower runners 3a, 3b are long members made of light steel (lightweight steel frame) formed into a groove-shaped C-section, and are fixed to the upper and lower frameworks 2a, 2b of the building (for example, the ceiling slab 2a and floor slab 2b) and extend in the width direction (left and right direction in Figure 1) of the partition wall 1. The upper and lower runners 3a, 3b extend in the width direction (hereinafter simply referred to as the "width direction") of the partition wall 1 at the upper and lower ends of the partition wall 1, and function as the lateral (width direction) framework of the partition wall 1. The upper runner 3a is fixed to the underside of the upper framework 2a with its groove (not shown) open downwards, and extends in the width direction along the underside of the upper framework 2a. The lower runner 3b is fixed to the upper surface of the lower body 2b with its groove (not shown) open upward, and extends in the width direction along the upper surface of the lower body 2b. In this embodiment, the upper and lower runners 3a, 3b are arranged approximately parallel to each other. Note that the upper and lower runners 3a, 3b only need to extend in the width direction of the partition wall 1, and do not have to be approximately parallel to each other.

[0017] As shown in Figures 1 to 3, the multiple studs 4 extend in the vertical direction (a predetermined direction) between the upper and lower runners 3a, 3b and function as the vertical (up-down) framework of the partition wall 1. The upper ends of the multiple studs 4 are inserted into the grooves of the upper runner 3a and fixed to the upper runner 3a. The lower ends of the multiple studs 4 are inserted into the grooves of the lower runner 3b and fixed to the lower runner 3b.

[0018] As shown in Figures 2 and 3, the partition 4 is composed of two vertically elongated studs 8, 8 made of light steel (lightweight steel frame material) and formed into a C-shaped groove in cross section. That is, the partition 4 has a pair of studs 8, 8 extending in the vertical direction. The stud 8 integrally includes a plate-shaped web 9 extending in the vertical direction and intersecting the width direction, and a pair of plate-shaped flanges 10a, 10b bending from both ends of the web 9 (both ends in the wall thickness direction (thickness direction of the partition wall 1)). The web 9 has a plurality of openings (not shown) formed at positions spaced apart from each other in the vertical direction to allow insertion of the anti-vibration members 5. The pair of flanges 10a, 10b is the flange 10a on the front side (the other side in the wall thickness direction) of the partition wall 1, and the flange 10b on the back side (one side in the wall thickness direction) of the partition wall 1, and they intersect the wall thickness direction. The tip portions 11 of the pair of flanges 10a, 10b are folded back in a roughly U-shape toward the inside (groove side) of the stud 8. The length of the stud 8 in the wall thickness direction (the distance between the surface of one flange 10a and the surface of the other flange 10b) is set slightly shorter than the length of the grooves of the upper and lower runners 3a, 3b in the wall thickness direction. The studs 4 stand back-to-back with the webs 9 of the pair of studs 8, 8 in contact with each other. The upper end of the stud 4 is inserted into the groove of the upper runner 3a and is supported by the upper runner 3a. The lower end of the stud 4 is inserted into the groove of the lower runner 3b and is supported by the lower runner 3b.

[0019] Fig. 4 is a perspective view of the clip 30. Fig. 5 is an explanatory diagram of how the clip 30 is attached to the stud 4, with (a) showing a state where only one end is locked, and (b) showing a state where the clip is attached with both ends locked.

[0020] As shown in FIGS. 3 to 5, the clip 30 is a component that is attached to the stud 4 to hold a pair of studs 8, 8 of the stud 4 back-to-back, and is formed by bending light steel (lightweight steel frame material). In this embodiment, the clip 30 is attached to adjacent flanges 10b, 10b on the back side of the pair of studs 8, 8 of the stud 4. In the following description, the directions related to the clip 30 refer to the directions in the clip-attached state in which the clip 30 is attached to the stud 4 (see FIGS. 3 and 5(b)).

[0021] The clip 30 comprises a middle plate portion (intermediate portion) 31 extending in the width direction along the surfaces of the flanges 10b on the back side of the pair of studs 8, 8, and a pair of locking portions 32, 32 standing upright from both ends in the width direction of the middle plate portion 31. The clip 30 is formed by bending a single plate-like member.

[0022] The middle plate portion 31 of the clip 30 is formed in a plate shape that intersects with the wall thickness direction and extends in the width direction (a direction that intersects with the up-down direction (predetermined direction)). When the clip is attached, the middle plate portion 31 abuts against the surfaces of the flanges 10b of the pair of studs 8, 8, and extends in the width direction along the surfaces of the flanges 10b, 10b, facing the surfaces of the flanges 10b, 10b. The widthwise length L1 of the middle plate portion 31 is set slightly longer than the widthwise length L2 of the flanges 10b of the pair of studs 8, 8 when they are back-to-back.

[0023] The pair of locking portions 32, 32 of the clip 30 are portions that lock onto the tip portions 11 of the flanges 10b, 10b of the pair of studs 8, 8, and stand upright from both widthwise edges of the mid-plate portion 31. One of the pair of locking portions 32, 32 in the widthwise direction locks onto the tip portion 11 of the flange 10b of one of the studs 8 in the widthwise direction, and the other locking portion 32 in the widthwise direction locks onto the tip portion 11 of the flange 10b of the other stud 8 in the widthwise direction. Claw portions 33 are formed on the tip sides of the pair of locking portions 32, 32 (tip sides in the direction away from the mid-plate portion 31) and protrude toward each other (toward the inside in the widthwise direction of the clip 30). The claw portions 33 are formed in a bead shape that extends vertically and protrudes toward the inside in the widthwise direction of the clip 30. In the attached state of the clip, the pair of locking portions 32, 32 abut against the tip portions 11 of the flanges 10b, 10b of the pair of studs 8, 8 from the outside in the width direction, restricting movement of the clip 30 in the width direction relative to the flanges 10b, 10b. In the attached state of the clip, the claw portions 33 lock the tip portions 11 of the flanges 10b, which are folded back in a substantially U shape, and restrict movement of the clip 30 to one side in the wall thickness direction relative to the flanges 10b, 10b of the pair of studs 8, 8.

[0024] When attaching the clip 30 to a partition 4, first, as shown in FIG. 5(a), the claw 33 of one of the locking portions 32 of the clip 30 in the width direction is locked onto the tip 11 of the flange 10b of one of the studs 8. Next, the other side of the clip 30 is tilted toward the flange 10b of the stud 8, using the side of one of the locking portions 32 of the clip 30 that is locked onto one of the studs 8 as an axis, and the claw 33 of the other locking portion 32 of the clip 30 is locked onto the tip 11 of the flange 10b of the other stud 8 (see FIG. 5(b)). With the clip attached, the clip 30 restricts the relative movement of the pair of studs 8, 8 that are back-to-back on the partition 4 in directions away from each other. At least one clip 30 is attached to each of the multiple partitions 4.

[0025] As shown in Figures 1 and 2, the anti-vibration member 5 is a member that connects multiple studs 4, and is attached to the studs 8 with spacer fittings (not shown) inserted through openings (not shown) provided in the webs 9 of the studs 8. In this embodiment, the anti-vibration member 5 is formed from light steel (lightweight steel frame) into a groove shape with a C-shaped cross section. However, the shape of the anti-vibration member 5 is not limited to a groove shape with a C-shaped cross section.

[0026] The gypsum board 6 is a rectangular board and is attached to the upper and lower runners 3a, 3b and the studs 8 of the multiple partition studs 4. In this embodiment, the gypsum board 6 includes a base board 12 fixed to the upper and lower runners 3a, 3b and the studs 8 of the multiple partition studs 4, and a finishing board 13 fixed to the surface side of the base board 12, and is provided on the front side of the partition wall 1. The base board 12 is made up of multiple gypsum boards 6 and is fixed to the upper and lower runners 3a, 3b and the studs 8 of the multiple partition studs 4 with screws 15 or the like. The base board 12 spans the multiple partition studs 4 and is fixed to the surface of the flange 10a on the front side of the studs 8 with screws 15 or the like. FIG. 2 shows the base board 12 fixed to the flange 10b of one of the pair of studs 8 of the partition stud 4 with the screw 15. The finishing board 13 is made up of multiple gypsum boards 6 and is fixed to the surface of the base board 12 with staples, adhesive, etc. Note that a cloth material may be adhered to the surface of the finishing board 13, or a finishing paint may be applied.

[0027] The insulating material 7 is a member for improving the thermal insulation of the partition wall 1, and is arranged in a plurality of spaces 14 (hereinafter referred to as "intra-wall spaces 14") partitioned by the upper and lower runners 3a, 3b and the studs 8 of the plurality of studs 4. In this embodiment, the insulating material 7 is made of glass wool (made of glass fiber), which is a fibrous insulating material. The insulating material 7 is arranged in the intra-wall spaces 14 and fixed to the back surface of the gypsum board 6 (in this embodiment, the base board 12). Note that in this embodiment, the insulating material 7 is made of glass wool, but the insulating material 7 is not limited to this and may be made of rock wool, for example, or may be a board made of foamed plastic.

[0028] In the partition wall 1 configured as described above, a pair of studs 8, 8 are held back to back by the clip 30 to form one partition post 4. Therefore, even if a large number of studs 8 are required to ensure the strength of the partition wall 1, for example, when the partition wall 1 is long in the height direction, it is possible to ensure a wide intra-wall space 14 in the width direction, unlike when the studs 8 are spaced evenly. This makes it possible to ensure the strength of the partition wall 1, and also to ensure a wide intra-wall space 14 in the width direction, defined by the upper and lower runners 3a, 3b and the studs 8.

[0029] The clip 30 also includes a central plate portion 31 extending widthwise along the surfaces of the flanges 10b of the pair of studs 8, and a pair of locking portions 32, 32 rising from both widthwise ends of the central plate portion 31. The pair of locking portions 32, 32 of the clip 30 lock onto the tip portions 11 of the flanges 10b, 10b of the pair of studs 8, 8 that are back-to-back on the partition wall 4. Therefore, with the clip attached, the clip 30 can restrict relative movement of the pair of studs 8, 8 that are back-to-back on the partition wall 4 in a direction away from each other. In this way, because the clip 30 can hold the pair of studs 8, 8 back-to-back, the pair of studs 8, 8 do not move apart when a load is applied to the partition wall 1, and the pair of studs 8, 8 can be integrated to ensure strength.

[0030] Therefore, according to this embodiment, the strength of the partition wall 1 can be ensured, and the intra-wall space 14 defined by the upper and lower runners 3a, 3b and the studs 8 can be ensured to be wide in the width direction.

[0031] 2, in this embodiment, the gypsum board 6 is fixed with a screw 15 to the flange 10b of one of the studs 8 of the stud 4. In this way, even when the gypsum board 6 is fixed to one of the studs 8 of the stud 4 but not to the other stud 8, the clip 30 can restrict relative movement of the pair of studs 8 of the stud 4 in directions away from each other.

[0032] Furthermore, the middle plate portion 31 of the clip 30 is formed in a plate shape that intersects with the wall thickness direction, and when the clip is attached, it faces the surfaces of the flanges 10b, 10b while abutting against the surfaces of the flanges 10b, 10b of the pair of studs 8, 8. This makes it possible to reduce the amount of protrusion of the clip 30 from the flanges 10b, 10b of the studs 8, 8, and therefore reduces interference of the clip 30 with the plasterboard 6 even when the plasterboard 6 is provided on the back side of the partition wall 1.

[0033] Furthermore, since the insulating material 7 is fixed to the back surface of the gypsum board 6 (in this embodiment, the base board 12), for example, after fixing the gypsum board 6 to the front side of the partition wall 1, the gypsum board 6 can be placed in the intra-wall space 14 from the back side of the partition wall 1 and easily fixed to the back surface of the gypsum board 6 on the front side using an adhesive or the like.

[0034] Furthermore, since the partition 4 is formed by holding a pair of studs 8, 8 back to back, unlike when, for example, the opening sides of the grooves of the pair of studs 8, 8 are made to face each other and formed into a rectangular tube, it is possible to insert insulating material 7 inside the grooves of the pair of studs 8, 8, thereby suppressing the occurrence of heat bridges.

[0035] In this embodiment, the upper and lower runners 3a and 3b are fixed to the upper and lower frames 2a and 2b of the building, but this is not limited to this, and the upper and lower runners 3a and 3b may be fixed to locations other than the upper and lower frames 2a and 2b.

[0036] In addition, in this embodiment, the upper and lower runners 3a, 3b, studs 8, and clips 30 are formed from lightweight steel frame material, but this is not limited to this and they may also be formed from other metal materials (e.g., stainless steel, aluminum, etc.).

[0037] In this embodiment, the gypsum board 6 is provided on the front side of the partition wall 1 but not on the back side, but the gypsum board 6 may be provided on both sides of the partition wall 1 in the wall thickness direction.

[0038] In addition, in this embodiment, the gypsum board 6 is a double-layered gypsum board 6 (a base board 12 and a finishing board 13), but this is not limited to this and the gypsum board 6 may be a single-layered or triple-layered or more.

[0039] Furthermore, in this embodiment, the gypsum board (board) 6 is fixed to the stud 4, but the board fixed to the stud 4 is not limited to the gypsum board 6, and may be, for example, plywood (board).

[0040] In addition, in this embodiment, the gypsum board 6 is fixed to the flange 10b of one of the pair of studs 8, 8 of the partition wall 4 with a screw 15, but it may also be fixed to the flanges 10b, 10b of both studs 8, 8 of the partition wall 4 with a screw 15.

[0041] Furthermore, in this embodiment, the plasterboard 6 is provided on the partition wall 1, but the plasterboard 6 does not have to be provided.

[0042] Furthermore, in this embodiment, the heat insulating material 7 is provided on the partition wall 1, but the heat insulating material 7 does not have to be provided.

[0043] FIG. 6 is a cross-sectional view showing a modified example of the partition wall 1. As shown in FIG.

[0044] 6, a pair of studs 8, 8 of a stud 4 may be held back-to-back by clips 30, and the webs 9 of the pair of studs 8, 8 may be fixed to each other with screws 51. The fixing pitch (spacing) of the screws 51 in the height direction is set to 1200 mm or less when the height of the partition wall 1 is up to 6 m, and to 600 mm or less when the height of the partition wall 1 is 6 to 7 m. Two screws 51 spaced apart in the wall thickness direction are provided at each height position to fix the webs 9 to each other. This prevents relative vertical misalignment between the pair of studs 8, 8, and firmly unites the pair of studs 8, 8, thereby functioning to ensure the strength of the partition wall 1. Furthermore, the relative movement (opening) of the pair of studs 8, 8 in the direction away from each other can be restricted by the screws 51 in addition to the clips 30, so the pair of studs 8, 8 can be firmly integrated and function to ensure the strength of the partition wall 1. This improves the earthquake resistance of the partition wall 1 during vibrations such as earthquakes.

[0045] In addition, in this embodiment, the middle plate portion (intermediate portion) 31 of the clip 30 is formed in a plate shape, but the shape of the intermediate portion is not limited to this. For example, in the case of a clip 30 that is attached to the surface of the stud 4 that does not have the gypsum board 6 fixed thereto, the intermediate portion of the clip 30 may be shaped to protrude from the flanges 10b, 10b of the studs 8, 8.

[0046] Furthermore, the shape of the clip 30 is not limited to that described above, and other shapes may be used as long as they are capable of locking the tip ends 11 of the flanges 10b, 10b of a pair of studs 8, 8 that are back-to-back.

[0047] Fig. 7 is a perspective view showing a modified example of clip 40, and shows the state where it is attached to the back side of stud 4. Fig. 8 is a perspective view showing a modified example of clip 40.

[0048] 7 and 8, for example, clip 40 is a component that is attached to a stud 4 to hold a pair of studs 8, 8 of the stud 4 back-to-back, and is formed by bending light steel (lightweight steel frame material). In the following description, the directions related to clip 40 refer to the directions in the clip-attached state in which clip 40 is attached to stud 4 (see FIG. 7).

[0049] The clip 40 comprises a pair of upper and lower middle plate portions (intermediate portions) 41, 41 extending widthwise along the surfaces of adjacent flanges 10b, 10b on the back side of a pair of studs 8, 8, and a pair of locking portions 42, 42 standing upright from both widthwise ends of the middle plate portions 41, 41.

[0050] The middle plate portions 41, 41 of the clip 40 are formed in the shape of plates that intersect in the wall thickness direction, extend in the width direction (a direction that intersects with the vertical direction (predetermined direction)) at positions spaced apart from each other vertically, and face the surfaces of the flanges 10b, 10b of a pair of studs 8, 8.

[0051] The pair of locking portions 42, 42 of the clip 40 are portions that lock onto the tips 11 of the flanges 10b, 10b of the pair of studs 8, 8, and stand up from both widthwise ends of the mid-plate portion 41, 41. One of the locking portions 42, 42 in the widthwise direction locks onto the tip 11 of the flange 10b of one of the studs 8 in the widthwise direction, and the other locking portion 42 in the widthwise direction locks onto the tip 11 of the flange 10b of the other stud 8 in the widthwise direction. The pair of locking portions 42, 42 are provided symmetrically on both sides of the clip 40 in the widthwise direction and have substantially the same configuration, so one will be described below and the other will not be described.

[0052] The locking portion 42 includes a pair of legs 43, 43 extending from the upper and lower middle plates 41, a connecting portion 44 connecting the tips of the pair of legs 43, 43 (the ends facing away from the middle plates 41, 41), and claw portions 45 protruding from the tips of the pair of legs 43, 43. The pair of legs 43, 43 are formed in a plate shape intersecting the vertical direction and extend from the upper and lower edges of the widthwise ends of the upper and lower middle plates 41, 41 (in this embodiment, they extend toward the other side in the wall thickness direction). The connecting portion 44 is formed in a plate shape intersecting the wall thickness direction and extends in the vertical direction, connecting the tips of the pair of legs 43, 43. The claw portions 45 are provided on each of the pair of plate-shaped legs 43, 43. The claw portions 45 protrude toward the inside of the widthwise direction of the clip 40. When the clip is attached, the claw portion 45 engages the tip portion 11 of the flange 10b folded back in a substantially U shape, and restricts movement of the clip 40 to one side in the wall thickness direction relative to the flange 10b of the stud 8.

[0053] When the clip is attached, the legs 43 of the pair of locking portions 42, 42 abut against the tip ends 11 of the flanges 10b, 10b of the studs 8, 8 from the outside in the width direction, restricting movement of the clip 40 in the width direction relative to the flanges 10b, 10b.

[0054] The clip 40 configured as described above has a pair of upper and lower middle plate portions (intermediate portions) 41, 41. That is, a space 46 is provided between the upper and lower middle plate portions 41, 41, thereby making it possible to reduce the weight.

[0055] Although the present invention has been described above based on the above embodiment, the present invention is not limited to the content of the above embodiment, and can be modified as appropriate without departing from the scope of the present invention. In other words, all other embodiments, examples, operational techniques, etc. made by those skilled in the art based on this embodiment are naturally included in the scope of the present invention.
