<Embodiment 1>
In the present embodiment, the upper and lower runners used for the drywall are fixed to a building frame (for example, a beam) using the runner fixture proposed in Japanese Patent Application No. 2013-148788. This runner fixing tool has a structure for fixing two runners to the housing for each mounting location.

  First, prior to the description of the runner fixing structure according to the present embodiment, a runner parallel running type dry wall which is a premise of the runner fixing tool will be briefly described. This dry wall structure has been filed as Japanese Patent Application No. 2012-262441.

(About drywall)
The dry walls according to the present embodiment are assumed to be partition walls that require high sound insulation such as boundary walls (door walls) in buildings where residential units such as apartment houses, tenement houses, and dormitories are continuous. The Such a dry wall is arranged to partition adjacent spaces (rooms). In the present embodiment, a virtual surface that partitions adjacent spaces is referred to as a “partition surface”, and a virtual line that partitions adjacent spaces in a cross section is referred to as a “partition line”. In the present embodiment, the thickness direction of the dry wall perpendicular to the partition surface is referred to as “front and back direction”.

  With reference to FIGS. 1-4, the structure of the drywall which concerns on Embodiment 1 of this invention is demonstrated.

  FIG. 1 is a longitudinal sectional view showing the structure of the drywall 1 according to the present embodiment. FIG. 2 is a partial cross-sectional view of the drywall 1 taken along the line II-II in FIG. In FIGS. 1 and 2, the right side of the drawing will be described as a first space, and the left side of the drawing will be described as a second space. Moreover, the imaginary line A1 in FIG. 2 shows a partition line, and arrow A2 has shown the front and back direction.

  With reference to FIG. 1 and FIG. 2, the drywall 1 includes a base member 2 disposed along a partition surface, and a surface member 4 fixed to one side and the other side of the base member 2. ing.

  The base member 2 includes a plurality of studs 21 arranged at intervals on the first space side and a plurality of studs 22 arranged at intervals on the second space side. These studs 21 and 22 are linearly aligned on the first space side and the second space side, respectively. Each of the studs 21 and 22 is made of steel, and the shape of the cross section is, for example, a substantially rectangular shape having a short side of 40 to 45 mm and a long side of 60 to 65 mm. In the present embodiment, the surface of the stud 21 on the first space side and the surface of the stud 22 on the second space side, that is, the side surface in contact with the surface member 4 are referred to as “surface”. The surface on the second space side of the stud 21 and the surface on the first space side of the stud 22, that is, the side surface opposite to the surface is referred to as “back surface”.

  The base member 2 is also a pair of runners 31 and 33 arranged so as to hold both axial ends of the plurality of studs 21 and a pair of runners arranged so as to hold both axial ends of the plurality of studs 22. 32, 34. The runners 32 and 34 on the second space side are arranged with a predetermined gap from the runners 31 and 33 on the first space side in the front and back direction.

  Thus, in this Embodiment, two runners are provided independently in the front and back direction for every attachment place. Therefore, as shown in FIG. 4, the sound S generated in the space on one side is cut off in the gap 3 between the runners 31 and 32, for example, also on the ceiling side to avoid propagation to the space on the other side. Can do. As a result, according to the dry wall 1 in the present embodiment, it is possible to satisfy the demand for higher sound insulation than a general sound insulation wall (FIG. 20) in which one runner is provided at each mounting location.

  Here, with reference to FIG. 2 and FIG. 3, the example of arrangement | positioning of several studs 21 and 22 is demonstrated. FIG. 3 is a diagram illustrating an arrangement example of the studs 21 and 22 of the drywall 1 according to Embodiment 1 of the present invention, and is a cross-sectional view of the drywall 1 when cut in the front and back direction.

  In a general dry wall, each stud is arranged with a strong axis, but in the present embodiment, each stud 21, 22 is arranged with a weak axis. That is, the studs 21 and 22 are arranged so that the short sides thereof are parallel to the direction orthogonal to the surface member 4 (front and back direction). In consideration of sound insulation, each of the studs 21 and 22 is preferably an open cross-section member having one long side (back side) having an opening rather than a closed cross-section tubular member. On the other hand, in the present embodiment, since the studs 21 and 22 are arranged with a weak axis, it is desirable that the studs having an open cross section are introduced only within a range in which the strength of the wall can be secured, that is, partially. For example, only the studs on the space side that particularly require strength may be open sections depending on the types of rooms (kitchen, living room, etc.) of the first space and the second space.

  Thus, in the present embodiment, the studs 21 and 22 are arranged on the weak axis. Therefore, when the distance L2 (FIG. 2) in the front-back direction between the stud 21 and the stud 22 is, for example, 10 mm, in the present embodiment, the distance between the opposing surface members 4, that is, the thickness L1 ( FIG. 3) is about 100 mm. As described above, according to the present embodiment, even if two runners are provided independently in the front and back directions for each mounting location, it is possible to avoid an increase in the thickness L1 of the foundation member 2.

  Note that the gap L2 between the first space-side stud 21 and the second space-side stud 22 is preferably set in a range of, for example, 5 mm to 15 mm. The lower limit value of the interval is a value at which at least the runner 31 (33) on the first space side and the runner 32 (34) on the second space side may have a gap in the front and back direction, and the upper limit value is the base member. This is a value considering the thickness between the two. The gap between the runners 32 and 34 (31, 33) may be determined according to the thickness of the entire wall, the method of fixing the runner, and the like.

  The plurality of studs 21 and 22 are also arranged in a staggered manner between the facing surface members 4. That is, the adjacent studs 21 and studs 22 are alternately arranged so as not to overlap in the front and back direction. In this embodiment, since there is a space (gap L2) between the studs 21 and 22 in the front and back direction, the stud 21 and the stud 22 may overlap at least partially in the front and back direction, or may overlap completely. May be.

  The plurality of studs 21 are arranged at a predetermined pitch along the partition line A1. The plurality of studs 22 are arranged at a predetermined pitch along the partition line A1 with the column 51 as the center. For example, a veneer board is disposed on the second space side of the column 51 as a base 52 to which the gypsum board 41 is attached. In each row (first space side or second space side), for example, glass wool is provided as a sound absorbing material 53 between the adjacent studs 21 (22). As a result, the sound absorbing material 53 is in close contact with the back surfaces of the studs 21 and 22, so that the sound generated from the space on one side is absorbed by the sound absorbing material 53 and the sound insulation is improved.

  In this embodiment, since the studs 21 and 22 are arranged in a weak axis, in order to secure the strength of the wall, the studs are arranged in each row rather than a general dry wall in which the stud is arranged in a strong axis. You may provide many. In that case, you may make the pitch which arrange | positions a stud small only in one part. For example, the pitch on the space side that particularly requires strength may be smaller than the other, depending on the type of room in each of the first space and the second space.

  Referring to FIGS. 1 and 3, each surface member 4 may be composed of a gypsum board 41 arranged on the base member 2 side and a reinforced gypsum board 42 arranged exposed on the space side. . The reinforced gypsum board 42 is a gypsum board (netted reinforced gypsum board) in which glass fibers and the like are mixed in order to enhance fire resistance. The reinforced gypsum board 42 is desirably larger than the thickness of the gypsum board 41 in order to improve fire resistance. Specifically, the thickness of the gypsum board 41 is, for example, 9.5 mm, and the thickness of the reinforced gypsum board 42 is, for example, 15 mm.

  The dry wall 1 described above is supported by beams 11 and 12 as upper and lower ends of the dry wall 1 as the building body of the building. The beams 11 and 12 are, for example, H-shaped steel. As shown in FIG. 1, when the upper end portion and the lower end portion of the dry wall 1 are supported by the beams 11 and 12, the upper runners 31 and 32 are fixed to the ceiling beam 11 and the lower runners 33 and 34, respectively.

It is clamped in the left-right direction by the restoring force of the parts 71, 73. The lower ends of the flange portions 311 and 312 of the runner 31 are supported by the folded portions 72 and 74 (engaging grooves 72a and 74a), respectively. Similarly, the runner 32 is inserted between the side surface portions 75 and 77 in a state where the side surface portions 75 and 77 of the holding member 7 are pushed and spread. Sandwiched between. The lower ends of the flange portions 321 and 322 of the runner 32 are supported by the folded portions 76 and 78 (engaging grooves 76a and 78a), respectively.

  The runner fixture 13 is provided with spring members on the upper side and the lower side of the plate-like portion 70, respectively. In the present embodiment, for example, two leaf springs 81 and 82 are provided as upper spring members. The leaf springs 81 and 82 are connected to the inner edges of the attachment portions 61 and 64 and extend obliquely upward from the attachment portions 61 and 64. Therefore, the upper surface 110a of the flange 110 of the beam 11 is pressed downward by the restoring force of the pressing claws 63 and 66, and the lower surface 110b is pressed upward by the restoring force of the leaf springs 81 and 82. Thereby, the flange 110 of the beam 11 is also clamped also in the up-down direction.

  As the lower spring member, for example, two leaf springs 83 and 84 that bias the runners 31 and 32 away from the plate-like portion 70 are provided. The leaf springs 83, 84 are connected to the front and back direction rear side edges of the attachment portions 61, 64, and extend obliquely downward through the holes 87, 88 formed in the plate-like portion 70. That is, the leaf spring 83 is disposed on the runner 31 side, and the leaf spring 84 is disposed on the runner 32 side. Therefore, the lower ends of the flange portions 311 and 312 of the runner 31 are supported by the folded portions 72 and 74, and the upper surface of the base portion 310 of the runner 31 is fixed while being pressed by the leaf spring 83.

The direction of the leaf springs 81 and 82 is not particularly limited as long as the leaf springs 81 and 82 extend upward and the leaf springs 83 and 84 extend downward.

  By making the runner fixture 13 as described above, it is possible to fix (lock) the runner fixture 13 to the flange 110 of the beam 11 at a single site on the spot. Further, by previously fixing the plurality of runner fixing tools 13 to the flange 110, the runners 31 and 32 can be fixed without bolts, and the positioning of the runners 31 and 32 can be facilitated. As a result, the on-site process can proceed smoothly.

  Moreover, in this Embodiment, the several runner fixing tool 13 is arrange | positioned at intervals along the direction where the runners 31 and 32 are extended. Therefore, even if the runner fixture 13 that collectively holds the runners 31 and 32 arranged in parallel with a gap is disposed, the sound insulation can be sufficiently improved as compared with a general dry wall.

  In the present embodiment, a plate member (plate-like portion 70) extending from the front side edge of the runner 31 to the front side edge of the runner 32 is provided on the holding member 7 side. A plate material may be provided. That is, the two attachment portions 61 and 64 of the locking member 6 may be formed as a single plate. In this case, the plate-like portion 70 of the holding member 7 is divided in the front and back direction, and a substantially inverted U-shaped member having the divided plate-like portions as the bottom surface portions 701 and 702 is a continuous plate material of the locking member 6. It may be fixed with a gap on the lower surface.

  As described above, when the upper runners 31, 32 are fixed to the beam 11, the lower ends of the flange portions 311, 312, 321, 322 of the runners 31, 32 are held by the runner fixture 13 by the leaf springs 83, 84. It is pressed against the engaging grooves 72a, 74a, 76a, 78a formed in the portions 710, 730, 750, 770. Therefore, the runners 31 and 32 can be stably fixed to the beam 11 by the runner fixture 13.

  On the other hand, when the lower runners 33 and 34 are fixed to the beam 12 by the runner fixing tool 13, the runner fixing tool 13 alone may not be able to appropriately fix it. This will be described with reference to FIG. 9 and FIG. In addition, when using the runner fixing tool 13 for the lower runners 33 and 34 in this way, in the above description of the runner fixing tool 13, the descriptions of “runner 31” and “runner 32” are respectively “runner 33”. And “runner 34”, and the description in the vertical direction may be reversed. Moreover, the runner fixing tool 13 shown by FIG. 6 etc. shall be latched by the beam 12 by the latching member 6. FIG.

  Here, for easy explanation, for example, the second space-side runner 34 of the lower two runners 33, 34 and the portion of the holding member 7 of the runner fixture 13 that fixes the runner 34 (hereinafter referred to as “runner 34”). Only the relationship with 700 (referred to as “runner holding portion”) is shown. FIGS. 9 and 10 are schematic views showing an ideal state and problems when the runner 34 is inserted into the runner holding portion 700 of the runner fixture 13 in the present embodiment.

  Referring to FIG. 9, when runner 34 is inserted into runner holding portion 700, ideally, base portion 340 that is the bottom wall of runner 34 is pushed upward by leaf spring 83 of runner fixture 13. ing. In this ideal state, similarly to the case where the upper runners 31 and 32 are fixed, the upper end portions of the flange portions 341 and 342 of the runner 34 are firmly in the engagement grooves 72a and 74a at the upper ends of the grip portions 710 and 730. It is pressed. Therefore, the runner 34 is appropriately held by the holding portions 710 and 730.

  However, in actuality, the leaf spring 83 has not only the weight of the runner 34 but also the weight of the stud 22 placed on the runner 34 and the weight of the surface member 4 attached to the surface of the stud 22. Is applied to the leaf spring 83. Then, the leaf spring 83 cannot maintain its urging force (restoring force), and the runner 34 sinks as shown in FIG. Then, the upper end portions of the side walls 341 and 342 of the runner 34 are not engaged with the engaging grooves 72a and 74a at the upper ends of the pair of gripping portions 710 and 730 of the runner fixture 13. As a result, the runner 34 may be detached from the runner fixture 13.

  In particular, in the dry wall 1 of the runner side-by-side type as in the present embodiment, the surface member 4 is provided only on the side of the flange 341 located on the front side of the flanges 341 and 342 of the runner 34. Therefore, when the surface member 4 is affixed at the construction stage, a large load is applied to the flange portion 341 side of the runner 34, so that the runner 34 is inclined counterclockwise in FIG. There arises a problem of disengagement from the holding part 700).

  Therefore, in the present embodiment, a fixing aid is used to prevent the lower runner 34 from being detached from the runner fixture 13 (runner holding portion 700).

(About the runner fixing structure using fixing aids)
FIG. 11 is a schematic diagram partially showing the runner fixing structure according to the present embodiment. 12 to 14 are a front view, a side view, and a bottom view, respectively, showing the fixing assisting tool 9. FIG. 15 is a perspective view showing a runner fixing structure according to the present embodiment.

  As shown in FIGS. 11 and 15, the fixing aid 9 is arranged on the runner 34 at the arrangement position of the runner fixture 13. As shown in FIG. 12, the fixing assisting tool 9 has a substantially U-shaped (U-shaped) cross section, and includes a bottom wall portion 90 and a pair of side wall portions 91 and 92. The bottom wall portion 90 is located along the upper surface of the base portion 340 of the runner 34. The pair of side wall portions 91 and 92 are located along the inner surfaces of the pair of flange portions 341 and 342 of the runner 34. Even when the fixing assisting tool 9 is used for fixing the upper runners 31 and 32, the one far from the bottom wall 90 is defined as the upper side of the fixing assisting tool 9.

  For example, two leaf springs 93 and 94 are provided on the lower surface (back surface) of the bottom wall portion 90 as spring members that abut against the upper surface of the bottom wall 340 of the runner 34 and urge the fixing auxiliary tool 9 away from the runner. Is provided. The leaf springs 93 and 94 are provided at approximately the center position in the front and back direction of the bottom wall portion 90, and extend so as to be inclined away from each other toward the lower end side. The height of the fixing assisting tool 9 is substantially equal to the length in the vertical direction of the grips 710 and 730 of the runner fixing tool 13.

  When the fixing assisting tool 9 is disposed on the runner 34, the fixing assisting tool 9 is fitted so as to be pressed from above. As shown in FIG. 15, nothing is placed on the fixing aid 9.

The engagement state with 910 and 920 is maintained. That is, the upper end portions 910 and 920 of the side wall portions 91 and 92 of the fixing assisting tool 9 are held by the grip portions 710 and 730 and function as engaging portions that are engaged with the engaging grooves 72a and 74a. The fixing assisting tool 9 may be configured such that the upper end portions 910 and 920 are firmly pressed into the engaging grooves 72a and 74a by the restoring force of the leaf springs 93 and 94.

  By covering such a fixing auxiliary tool 9 on the runner 34, the runner 34 can be prevented from being detached from the runner fixing tool 13 (runner holding portion 700). Therefore, according to the present embodiment, when the lower runner 34 is fixed to the beam 12, the runner can be stably moved by using the runner fixing unit including the runner fixing tool 13 and the fixing auxiliary tool 9. Can be fixed. As shown in FIG. 15, the fixing assisting tool 9 is also put on the runner 33, so that the runners 33 and 34 are prevented from being detached from the runner fixing tool 13.

  In addition, the shape of the fixing auxiliary tool 9 is not limited to the above shape. Modification examples of the fixing assisting tool 9 are shown below.

(Modification example of fixing aid)

Similarly, it is desirable that the upper end edge of the side wall portion 92 </ b> A has a shape including a top portion 921 and inclined portions 922 and 923 that are inclined downward from the top portion 921. In the mounted state, the top portions 911 and 921 of the side wall portions 91A and 92A of the fixing assisting tool 9A are brought into contact with the engagement grooves 72a and 74a of the grip portions 710 and 730, respectively. Note that the top portions 911 and 921 may both be formed in a dot shape or a linear shape.

  When the side wall portions 91A and 92A have such a shape, when the fixing auxiliary tool 9A is installed at the attachment position shown in FIG. 18, it is slid and inserted so as to be inclined and rotated as shown in FIG. be able to. That is, the inclined portion 913 (923) in the traveling direction can be inserted from the side of the runner fixture 13 in the direction in which the runner 34 extends while abutting the ends of the grip portions 710 and 730 of the runner fixture 13. . Alternatively, the fixing assisting tool 9A can be once placed on the runner 34 at a position away from the runner fixing tool 13 without being inclined, and inserted into the runner fixing tool 13 by sliding it as it is.

<Embodiment 2>
The fixing aid in the present embodiment also has a substantially U-shaped cross section, but the orientation of the fixing aid in the attached state is different from that in the first embodiment. Below, only the part different from Embodiment 1 is demonstrated in detail about the runner fixing structure which concerns on this Embodiment.

  FIG. 20 is a perspective view showing a fixing assisting tool 9B according to Embodiment 2 of the present invention. 21 and 22 are a perspective view and a schematic cross-sectional view, respectively, partially showing a runner fixing structure according to Embodiment 2 of the present invention. FIG. 23 is a diagram schematically illustrating the installation method of the fixing assisting device according to the second embodiment of the present invention.

  Referring to FIGS. 20 to 22, in the present embodiment, in the mounted state, fixing auxiliary tool 9 </ b> B is disposed sideways so that bottom wall portion 90 </ b> B is orthogonal to a pair of side walls 341, 342 of runner 34. Has been. Leaf spring portions 914 and 924 that elastically contact the side walls 341 and 342 of the runner 34 are provided on the pair of side wall portions 91B and 92B of the fixing assisting tool 9B, respectively. The leaf spring portions 914 and 924 extend obliquely downward (bottom wall portion 90B side) outward from the side wall portions 91B and 92B.

  When the fixing assisting tool 9B is installed at the attachment position shown in FIG. 21, first, as shown by the one-dot chain line in FIG. 23, the side walls 91B and 92B are located at positions away from the runner fixing tool 13 (runner holding part 700). The most of the fixing assisting tool 9 </ b> B is inserted into the runner 34 with the upper end portion thereof facing downward. Thereafter, the fixing assisting tool 9B is rotated about 90 degrees so that the upper ends of the side wall parts 91B and 92B are in the forward direction, and is slid to the position of the runner fixing tool 13. Desirably, the bottom wall portion 90 </ b> B of the fixing assisting tool 9 </ b> B is slid to a position where it abuts against the ends of the gripping portions 710 and 730 of the runner fixing tool 13. Thereby, the side edge portions 915 and 925 of the side wall portions 91B and 92B are engaged with the engaging grooves 72a and 74a of the grip portions 710 and 730 of the runner fixture 13.

  In the present embodiment, it is not necessary to press against the bottom wall 340 of the runner 34 when attaching the fixing assisting tool 9B, so that the fixing assisting tool 9B can be easily inserted. Further, since the area in contact with the runner 34 is smaller than the fixing assisting tool 9A shown in the modification of the first embodiment, the fixing assisting tool 9B can be smoothly slid.

  In the present embodiment, the leaf spring portions 914 and 924 extend obliquely downward when the bottom wall portion 90B is downward, but both of them are inclined downward in the attached state. It may extend. That is, the leaf springs 914 and 924 may extend obliquely to the side when the bottom wall portion 90B is downward. By doing in this way, since it becomes unnecessary to rotate the fixing auxiliary tool 9B as mentioned above, a fixing auxiliary tool can be inserted in the runner 34 more easily.

<Embodiment 3>
Also in the present embodiment, the fixing aid has a substantially U-shaped cross section, but the orientation of the fixing aid in the attached state is different from that of the first embodiment. Below, only the part different from Embodiment 1 is demonstrated in detail about the runner fixing structure which concerns on this Embodiment.

  FIG. 24 is a perspective view showing a fixing assisting tool 9C according to Embodiment 3 of the present invention. FIG. 25 is a perspective view partially showing a runner fixing structure according to Embodiment 3 of the present invention.

  Referring to FIGS. 24 and 25, in the present embodiment, in the mounted state, fixing auxiliary tool 9 </ b> C is disposed sideways so that bottom wall portion 90 </ b> C is orthogonal to a pair of side walls 341, 342 of runner 34. Has been. One side wall portion 91C of the fixing assisting tool 9C is located on the bottom wall 340 of the runner 34, and the other side wall portion 92C is disposed substantially parallel to the side wall portion 91C. Wing-like portions 97 and 98 that rise so as to be fitted into the grip portions 710 and 730 of the runner fixture 13 are provided on the side edge portions of the side wall portion 92C. The wing-like portions 97 and 98 extend outward in the oblique direction from the respective side edge portions of the other side wall portion 92C.

  In the present embodiment, the fixing auxiliary tool 9B is inserted on the runner 34 so that the bottom wall portion 90C is on the front side in the traveling direction, and is slid as it is to the position of the runner fixing tool 13. Thereby, the wing-like portions 97 and 98 of the side wall portions 91C and 92C are engaged with the engaging grooves 72a and 74a of the grip portions 710 and 730 of the runner fixture 13 at least in a part thereof.

  The bottom wall 90C may be provided with a hole 900 so that the bottom wall 90C can be pulled in the moving direction when the fixing assisting tool 9C is moved.

  In addition, as shown in the drawing, the wing-like portions 97 and 98 may be provided with a top portion 980 that protrudes to the side (that is, the upper side in the attached state). The top portions 970 and 980 are provided, for example, on the upper end side (the rear side in the traveling direction) of the wing-like portions 97 and 98. In this case, the gripping portions 710 and 730 of the runner fixture 13 are provided with engagement holes 710 a and 730 a for receiving the top portions 970 and 980. This facilitates positioning and fixing of the fixing assisting tool 9C.

  Also in the present embodiment, it is not necessary to press against the bottom wall 340 of the runner 34 when attaching the fixing assisting tool 9C, so that the fixing assisting tool 9C can be easily inserted. Further, since the wing-like portions 97 and 98 are formed so as to hardly contact the side walls 341 and 341 of the runner 34, the fixing assisting tool 9C can be smoothly slid.

<Embodiment 4>
In each said embodiment, the fixing assistance tool was attached to the runner fixing tool of a runner parallel running type. On the other hand, in this Embodiment, a fixing auxiliary tool is attached to the runner fixing tool which is not a runner parallel running type. This runner fixing tool has the shape shown by the said patent 4241322 gazette (patent document 1), for example. Below, only the difference with Embodiment 1 is demonstrated in detail about the runner fixing structure which concerns on this Embodiment.

  FIG. 26 is a longitudinal sectional view showing the structure of the drywall 1A according to Embodiment 4 of the present invention. FIG. 27 is a cross-sectional view showing a runner fixing structure according to Embodiment 4 of the present invention.

  Referring to FIG. 26, in the present embodiment, dry wall 1A includes runners 32A and 34A one above the other. The lower runner 34 </ b> A holds the lower ends of the plurality of studs 21 </ b> A and 22 </ b> A arranged along the partition surface from below. In the present embodiment, the studs 21A on the first space side and the studs 22A on the second space side are arranged in a staggered manner so as to partially overlap in the front and back direction. The studs 21A and 22A are arranged with a strong axis. Therefore, the length of the bottom wall 340 </ b> A of the runner 34 </ b> A (between both flanges) is about twice the length of the bottom wall 340 of the runner 34 of the first embodiment. For example, spacers 35 are inserted in the space on the back side of the stud 21A and the back side of the stud 22A.

  When the runner 34A of the dry wall 1A is fixed to the beam 12, a runner fixing tool 13A as shown in FIG. 27 is used. 13 A of runner fixing tools differ from the runner fixing tool 13 of Embodiment 1 only in the shape of a holding member.

  Referring to FIG. 27, the holding member 7A of the runner fixture 13A only needs to hold one runner 34A, and thus has a shape that does not have the central gripping portions 730 and 770 shown in FIG. That is, the holding member 7A includes a plate-like portion 70 and a pair of grip portions 710 and 750 that grip the flange portions 341 and 342 of one runner 34A from the outside. In this case, the leaf springs 83 and 84 extending obliquely upward from the plate-like portion 70 are both in contact with the wide base portion 340A of the runner 34A.

  Also in the dry type wall 1A as in the present embodiment, the leaf springs 83, 84 are based on the weight of the runner 34A and the weight of the studs 21A, 22A and the face member 4 loaded on the runner 34A. 340 is pressed down. Accordingly, in this case as well, the tip portions of the flange portions 341 and 342 of the runner 34A are disengaged from the engaging grooves 72a and 76a of the grip portions 710 and 750 of the runner fixture 13A. In the present embodiment, unlike the first embodiment, the surface members 4 are arranged on the outer sides of the flange portions 341 and 342 of the runner 34A. Therefore, in the completed state, the surface member 4 is shifted to one flange portion side of the runner 34A. No load is applied. However, in the construction stage, the surface member 4 is attached in order to the first space side and the second space side. Therefore, in a state in which the surface member 4 is attached only to one side, the load is applied to the one heel side of the runner 34A. Therefore, even when only one runner 34A is fixed to the beam 12 as in the present embodiment, there may be a case where the runner 34A is detached from the runner fixture 13A.

  Therefore, also in the present embodiment, the fixing assisting tool 9D is arranged at a position overlapping the arrangement position of the runner fixing tool 13A. The other is the same except that the width (length in the front and back direction) of the bottom wall portion 90D of the fixing assisting tool 9D is wider than the bottom wall portion 90 of the fixing assisting tool 9 shown in the first embodiment. Therefore, also in the present embodiment, when the fixing assisting tool 9D is mounted on the runner 34A, the fixing assisting tool 9D itself is biased upward by the plate springs 93, 94 of the fixing assisting tool 9D, and the runner fixing tool 13A. The engagement state between the pair of gripping portions 710 and 750 and the upper end portions 910 and 920 of the pair of side wall portions 91 and 92 of the fixing assisting tool 9D is maintained. As a result, it is possible to prevent the runner 34A from being detached from the holding member 7A of the runner fixture 13A.

  In each of the above-described embodiments, the leaf springs 83 and 84 are provided on the holding member of the runner fixture. However, when it is assumed that the above-mentioned fixing aid is used, the leaf springs 83 and 84 are provided. It does not have to be. When the runner fixing tool does not have the leaf springs 83 and 84, the fixing assisting tool according to each embodiment may be used for the upper runners 31 and 32 as well. Thereby, the upper runner can be stably fixed to the beam 11.

  Moreover, in each embodiment, although the structure which fixes a runner to the beam of a building was shown, you may fix to the foundation of a building. In that case, the runner fixture may not have a locking member. For example, the runner fixing tool may be fixed to the foundation by a nail material such as a bolt penetrating substantially the center position of the plate-like portion of the holding member.

  Moreover, you may combine suitably each above-mentioned embodiment and modification.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
