Description

  The present invention relates to a wall structure of a building such as a warehouse, a wall construction method, and a reinforcing tool, and more particularly, to a building wall structure, a wall construction method, and a reinforcing tool that employ a lightweight steel frame.

  As the pillar material (stud) of the wall of the building adopting the lightweight steel frame, square steel having a closed section or C-shaped steel (grooved steel) having an open section having an opening on one side is used.

  For example, as a pillar material for a boundary wall for partitioning dwelling units, as shown in Japanese Patent Laid-Open No. 8-82026 (Patent Document 1) and Japanese Utility Model Laid-Open No. 7-29111 (Patent Document 2), a substantially grooved stud is used. It is used. In these documents, deformation of the stud is suppressed by fitting a plurality of spacers into the stud at regular intervals in the vertical direction.

  On the other hand, for example, square steel is generally used as a pillar material for walls that require relatively high strength, such as an outer wall and a partition wall of a warehouse.

JP-A-8-82026 Japanese Utility Model Publication No. 7-29111

  As described above, square steel is generally used as a column for walls that require relatively high strength, but square steel is more expensive than C-type steel. Therefore, in order to suppress the manufacturing cost of the wall, it is considered effective to change the wall column material from square steel to C-shaped steel.

  However, such C-type studs have lower strength than square-type studs, so when high out-of-plane loads are applied to C-type studs, the studs rotate in the upper and lower runners due to twisting. There is a risk of falling off the runner. Therefore, it is difficult to adopt a C-shaped stud as it is (as a single unit) as a wall pillar material that requires strength.

  Also, as shown in Patent Documents 1 and 2, studs fitted with a plurality of spacers are sometimes used as pillar materials for houses and the like, but the strength of the wall can be obtained only by fitting conventional spacers into C-shaped steel. Cannot be improved sufficiently.

  The present invention has been made to solve the above-described problems, and its object is to provide a wall structure of a building and a wall construction method capable of reducing wall costs and improving strength. It is to be.

  Another object is to provide a reinforcing tool used in such a wall structure.

  A wall structure of a building according to an aspect of the present invention includes a pair of runners spaced apart from each other in the vertical direction, and a plurality of upper ends and lower ends fitted into the pair of runners, each having a pair of edges. A C-shaped stud, and a reinforcing tool that is attached to at least one of the upper end portion and the lower end portion of the stud and prevents the stud from being contracted in a direction in which the distance between the pair of edge portions is reduced. The reinforcing tool is a pair of first plate-like portions disposed on one surface side of the pair of edge portions of the stud, and a pair of members disposed substantially parallel to the first plate-like portion on the other surface side of the pair of edge portions. The edge portion of the stud is sandwiched between the first plate portion and the second plate portion of the reinforcing tool.

  Preferably, the reinforcing tool further includes a main body portion located between the pair of edge portions of the stud and connected to the pair of first plate-like portions and the pair of second plate-like portions.

  Preferably, the main body portion is arranged on one side of the edge portion, and a boundary portion between the main body portion and each second plate-like portion is arranged in a face-to-face state on the end surface of the edge portion.

  Preferably, the first plate-like part is positioned above or below the second plate-like part in the attached state, and the vertical length of the second plate-like part is the vertical direction of the first plate-like part. Longer than the length.

  Preferably, the distance between the first plate-like portion and the second plate-like portion is smaller than the plate thickness dimension of the stud.

  It is desirable that at least one of the first plate-like portion and the second plate-like portion has a convex portion on the facing surface facing the edge portion. In this case, the distance between the apex of the convex portion of one plate-like portion and the opposing surface of the other plate-like portion, or the distance between the apexes of the convex portions of the first and second plate-like portions is the stud plate. It is smaller than the thickness dimension.

  When the pair of first plate-like portions is provided at a position higher than the second plate-like portion, the reinforcing tool is connected to the main body portion at a position lower than the second plate-like portion, and one surface of the edge portion. It is desirable to further include a pair of third plate-like portions arranged along the line. In this case, it is more desirable that the edge portion of the stud is sandwiched between the first plate-like portion and the third plate-like portion located on one side and the second plate-like portion located on the other side.

  The construction method of the building wall according to another aspect of the present invention includes a step of arranging a pair of runners spaced apart from each other in the vertical direction, a pair of first plate-like portions, and a substantially parallel to the first plate-like portion. And a step of preparing a reinforcing tool including a pair of second plate-like portions disposed on the end of the C-shaped stud having a pair of edges, the distance between the pair of edges is reduced beyond an allowable value. In order to prevent this, the method includes a step of attaching the reinforcing tool by sandwiching the edge portion between the first plate-like portion and the second plate-like portion, and a step of fitting the end portion of the stud to which the reinforcing tool is attached to the runner. .

  Preferably, in the step of attaching the reinforcing tool, the reinforcing tool is inserted into the edge portion of the stud from the vertical edge of the stud.

  A reinforcing tool according to still another aspect of the present invention is a C-shaped stud reinforcing tool whose upper end and lower end are held by a pair of runners, and is disposed on one side of a pair of edges of the stud. A pair of first plate-like portions and a pair of second plate-like portions disposed substantially parallel to the first plate-like portion on the other surface side of the pair of edge portions of the stud. The reinforcing tool is attached to the stud in a state where the edge is sandwiched between the first plate-like portion and the second plate-like portion, and prevents the stud from being reduced in a direction in which the distance between the pair of edges is reduced.

  Preferably, the distance between the first plate-like portion and the second plate-like portion is smaller than the plate thickness dimension of the stud.

  According to the present invention, the cost of the wall can be reduced and the strength can be improved.

  Embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

(About the schematic structure of the wall structure)
A schematic configuration of the wall structure 1 according to the present embodiment will be described with reference to FIGS. 1 and 2. The wall structure 1 is a structure of a partition wall (partition wall) W that partitions two adjacent spaces in a building. The virtual surface 90 shown in FIGS. 1 and 2 is a partition surface that partitions two adjacent spaces. 1 and 2, the vertical direction (vertical direction) of the partition surface 90 is indicated by an arrow A1, and the horizontal direction (horizontal direction) of the partition surface 90 is indicated by an arrow A2. In FIG. 2, the direction orthogonal to the partition surface 90 is indicated by an arrow A3. The direction of the arrow A3 corresponds to the out-of-plane direction of the partition wall W.

  The wall structure 1 includes a pair of runners 2 and 3 that are spaced apart from each other in the vertical direction, and a plurality of studs 4 that are held by the pair of runners 2 and 3 and are spaced apart from each other.

  The runner 2 is located at the lower end of the partition wall W, and the runner 3 is located at the upper end of the partition wall W. Each runner 2, 3 has a substantially U-shaped cross section. That is, the runner 2 has a pair of flange portions 22 at both ends in the width direction. Similarly, the runner 3 has a pair of flange portions 32 at both ends in the width direction. The width direction of the runners 2 and 3 coincides with the direction orthogonal to the partition surface 90.

  The lower end of each flange portion 22 is connected to the bottom surface portion 21 that is in surface contact with the upper surface of the frame portion 91 such as a beam. The upper end of each collar portion 32 is connected to the top surface portion 31 that is in surface contact with the lower surface of the housing portion 92 such as a beam.

  Each stud 4 has an upper end and a lower end fitted into the pair of runners 3 and 2, respectively. The stud 4 is a C-shaped steel having a substantially rectangular shape (rectangular shape), and an opening 40 extending in the vertical direction is formed on one (one side) of the pair of long sides. That is, the stud 4 includes a long side portion 41 having no opening, a pair of short side portions 42 orthogonal to the long side portion 41, and a pair of edge portions 43 located on both sides in the width direction of the opening 40. The pair of edge portions 43 have end faces that face each other.

  The stud 4 is arranged with a strong axis so that the long side portion 41 coincides with a direction (out-of-plane direction) orthogonal to the partition surface 90. In this case, the face material 80 (FIG. 1) is fixed to the short side portion 42 of the stud 4. The face material 80 is, for example, a gypsum board. In the following description, the state in which the upper end portion and the lower end portion of the stud 4 are fitted into the runners 3 and 2 is referred to as an installation state of the stud 4.

  As the stud 4, C-type steel that is generally distributed is adopted, and the prescribed outer width dimension (the prescribed width dimension of the long side portion 41) is, for example, 100 mm. In this case, the interval between the flange portions 22 and 32 of the runners 2 and 3 is also 100 mm, for example. The prescribed width dimension of the opening 40 of the stud 4 is, for example, 60 mm, and the prescribed width dimension of each edge 43 is, for example, 20 mm. The plate thickness dimension (dimension D1 shown in FIG. 4) of the stud 4 is desirably 1.2 mm or more, and more desirably 1.6 mm or more.

  Since such a stud 4 is cheaper than a square steel having a plate thickness of 1.2 mm, for example, the cost of the partition wall W can be reduced as compared with the case where the square steel is used as a column material.

  On the other hand, the load resistance in the out-of-plane direction of such a C-shaped stud 4 is lower than that of square steel. Therefore, in this embodiment, one reinforcing tool 5 is attached to each of the lower end portion and the upper end portion of each stud 4. The reinforcing tool 5 prevents the stud 4 from being reduced and deformed in a direction in which the distance between the pair of edge portions 43 of the stud 4 is reduced. That is, the reinforcing tool 5 prevents the interval between the end surfaces of the pair of edge portions 43 from becoming less than a predetermined opening width dimension.

  In addition, the reinforcing tool 5 attached to the upper end part of the stud 4 should just be located above the lower end height of the collar part 32 of the runner 3 at least one part (upper part). Similarly, it is only necessary that at least a part (lower part) of the reinforcing tool 5 attached to the lower end portion of the stud 4 is positioned below the upper end height of the flange portion 22 of the runner 2.

(About the mounting structure of the reinforcement)
With reference to FIGS. 3-6, the attachment structure of the reinforcement tool 5 in the installation state of the stud 4 is demonstrated. FIG. 3 is an enlarged view of the region III shown in FIG. 2, and is a perspective view showing a state in which the reinforcing tool 5 is attached to the upper end portion of the stud 4. 4 is a cross-sectional view of the mounting structure of the reinforcing member 5 cut along the line IV-IV in FIG. FIG. 5 is a plan view of the reinforcing tool 5. 6 is a cross-sectional view of the reinforcing tool 5 cut along the line VI-VI in FIG.

  The outer width L1 of the stud 4 in the installed state of the stud 4 shown in FIGS. 3 and 4 corresponds to the above-mentioned specified outer width dimension (for example, 100 mm). Similarly, the opening width L2 of the stud 4 in the installed state of the stud 4 corresponds to the specified width dimension of the opening 40 described above.

  As shown in FIGS. 3 and 4, the reinforcing tool 5 has a substantially rectangular shape in plan view, and is disposed across a pair of edge portions 43 of the stud 4. The lateral width dimension L11 of the reinforcing tool 5 is smaller than the prescribed outer width dimension (L1) of the stud 4 and larger than the prescribed opening width dimension (L2) of the stud 4. The vertical dimension L13 of the reinforcing tool 5 is typically equal to or smaller than the length dimension of the flange portion 32 of the runner 3.

  The reinforcing tool 5 is connected to the body portion 51 located between the pair of edge portions 43 of the stud 4 and both ends in the width direction of the body portion 51, and two pairs of front side plates disposed along the surface of the edge portion 43. A pair of back side plate-like portions (first plate-like portion and third plate-like portion) 52, 53 and a pair of back side plate-like portions (which are connected to both ends in the width direction of the main body portion 51) and arranged along the back surface of the edge portion 43 ( 2nd plate-shaped part) 54. The edge portion 43 of the stud 4 is sandwiched between the front side plate-like portions 52 and 53 and the back side plate-like portion 54 of the reinforcing tool 5.

  The reinforcing tool 5 is formed symmetrically. Therefore, each pair of the plate-like parts 52 to 54 has substantially the same vertical length, and is provided at substantially the same position in the vertical direction.

  The reinforcing tool 5 is formed, for example, by processing a single metal thin plate. Therefore, in this Embodiment, the front side plate-shaped parts 52 and 53 and the back side plate-shaped part 54 are arrange | positioned, without overlapping in an up-down direction. That is, the front side plate-like portions 52 and 53 and the back side plate-like portion 54 do not face each other in the front-back direction. As shown in FIG. 3, the pair of front side plate-like portions 52 are located above the pair of back side plate-like portions 54, and the other pair of front side plate-like portions 53 are more than the pair of back side plate-like portions 54. Is also located below.

  The main body 51 is a plate-like portion located on the surface side of the edge 43 of the stud 4. Therefore, the main body 51 and the front side plate-like parts 52 and 53 are connected in a flush manner. On the other hand, the boundary part 55 which cross | intersects these and extends in the front-back direction is interposing between the main-body part 51 and each back side plate-shaped part 54. The pair of boundary portions 55 also have substantially the same vertical length and are provided at substantially the same position in the vertical direction.

  The intersection angle between each boundary portion 55 and the main body portion 51 is substantially a right angle. The term “substantially perpendicular” means 80 ° or more and 100 ° or less. The crossing angle between each boundary portion 55 and the main body portion 51 may be an obtuse angle exceeding 100 °. Further, each boundary portion 55 may have a curved shape.

  The interval (maximum distance in the width direction) L12 between the outer surfaces of the two boundary portions 55 is determined so as to substantially match the prescribed opening width dimension (L2) of the stud 4. Therefore, in the installation state of the stud 4, the outer surface of the boundary portion 55 is in contact with the end surface of the edge portion 43 (surface contact or line contact). Depending on the processing accuracy of the stud 4, a slight gap may exist between the outer surface of the boundary portion 55 and the end surface of the edge portion 43 in the installed state of the stud 4. In other words, in the installed state of the stud 4, if the boundary portion 55 is disposed facing the end surface of the edge portion 43 of the stud 4, the outer surface of the boundary portion 55 is not in contact with the end surface of the edge portion 43. It may be.

  Referring to FIG. 5, the length dimension L15 of the upper front side plate-like portion 52 and the length dimension L16 of the lower front side plate-like portion 53 are substantially equal. The length dimension L14 of the back side plate-like part 54 is desirably larger than the dimension obtained by adding the length dimensions L15 and L16 of the upper and lower two front side plate-like parts 52 and 53. Specifically, the length dimension L14 of the back side plate-like portion 54 is, for example, 30 mm, and the length dimensions L15, L16 of the front side plate-like portions 52, 53 are, for example, 10 mm. In this case, since the area of the boundary portion 55 that abuts against the end surface of the edge portion 43 of the stud 4 can be made relatively large, when a large force is applied to the side surface of the stud 4 from the outside (hereinafter also referred to as “when loaded”). The pair of edge portions 43 of the stud 4 can be effectively stretched by the main body portion 51 and the boundary portion 55.

  Referring to FIG. 6, the distance D <b> 12 between the front side plate-like portions 52, 53 and the back side plate-like portion 54 is smaller than the plate thickness dimension D <b> 1 (FIG. 4) of the stud 4. Thereby, the edge part 43 of the stud 4 is firmly clamped by the front side plate-like parts 52 and 53 and the back side plate-like part 54 in the attachment state of the reinforcing tool 5.

  In the present embodiment, the back surfaces of the front side plate-like portions 52 and 53 (that is, the facing surface where the front side plate-like portions 52 and 53 face the surface of the edge portion 43) and the front surface (ie, the back side plate). 6 is slightly larger than the plate thickness dimension D1 of the stud 4, but as shown in FIG. A convex portion 56 as a projection is provided on the back surface of the projection. The reinforcing tool 5 is formed such that the distance D12 between the apex of the convex portion 56 and the surface of the back side plate-like portion 54 is smaller than the plate thickness dimension D1 (FIG. 4) of the stud 4.

  Specifically, when the plate thickness dimension D1 of the stud 4 is 1.6 mm, the distance D11 is, for example, 2.0 mm, and the distance D12 is, for example, 1.5 mm. Thus, since each front side plate-like part 52 and 53 has the convex part 56, since frictional resistance arises between the edge 43 and the convex part 56 of the stud 4, it is not necessary to use fixing tools, such as a screw. Moreover, it can prevent that the reinforcing tool 5 falls by dead weight.

(Construction method for partition wall)
Next, the construction method of the partition wall W is demonstrated easily. In this Embodiment, the construction method of the partition wall W is the process P1 which arrange | positions a pair of runners 2 and 3, the process P2 which prepares the reinforcement tool 5, and attaches the reinforcement tool 5 to the upper end part and lower end part of the stud 4, respectively. The process P3 and the process P4 which inserts the upper end part and lower end part of the stud 4 to which the reinforcement tool 5 was attached to the runners 3 and 2 are included. In addition, the construction order of the process P1 and the processes P2 and P3 may be reversed.

  In step P3, as shown in FIG. 7, the reinforcing tool 5 is inserted (struck) into the edge 43 of the stud 4 from the vertical edge of the stud 4 while standing up and down. As described above, the distance D11 between the back surface of the front plate portions 52 and 53 of the reinforcing member 5 and the surface of the back plate portion 54 is slightly larger than the plate thickness dimension D1 of the stud 4. Therefore, when attaching the reinforcing tool 5, the reinforcing tool 5 is slid along the longitudinal direction of the stud 4 in a state where the edge 43 is sandwiched between the lower front plate part 53 and the back plate part 54. be able to.

  Moreover, since the front side plate-shaped parts 52 and 53 of the reinforcing tool 5 have the convex part 56 on the back surface side, the reinforcing tool 5 can be temporarily fixed to the stud 4 at a desired position. In addition, the reinforcing tool 5 attached to the upper end portion of the stud 4 is arranged with a little left upper end of the stud 4.

  Here, the stud 4 is a C-shaped steel having the opening 40 as described above. Therefore, the opening width L22 (FIG. 7) of the stud 4 before being installed on the runners 2 and 3 (at the time of purchase) is often larger than the prescribed opening width dimension (L2). Therefore, the external width L21 (FIG. 7) on the opening 40 side of the stud 4 before being installed on the runners 2 and 3 is generally about 2 to 3 mm larger than the predetermined external width dimension (L1). .

  In the process P3, in the stage which attached the reinforcing tool 5 to the upper end part and lower end part of the stud 4, the external width and opening width of the stud 4 do not change in particular. Therefore, at this stage, a gap C of, for example, about 1 to 2 mm exists between each boundary portion 55 of the reinforcing tool 5 and the end surface of the edge portion 43 of the stud 4.

  Since the reinforcing member 5 is only attached to the stud 4 by the frictional resistance between the convex portion 56 of the reinforcing member 5 and the surface of the edge portion 43 of the stud 4, the stud 4 is slightly inclined to open the opening in the process P4. When the long side portion 41 without 40 is fitted into the runner 3 first, the long side portion with the opening 40 is naturally contracted in the width direction. That is, the stud 4 bends in a direction in which the pair of edge portions 43 approach each other and is gradually contracted in the width direction. Thereby, since the outer side surface of the boundary portion 55 of the reinforcing tool 5 comes into contact (or close proximity) to the end surfaces of the pair of edge portions 43 of the stud 4, each boundary portion 55 of the reinforcing tool 5 before the stud 4 is installed A gap C (FIG. 7) between the edge 43 of the stud 4 and the end face is substantially 0 mm.

  When the stud 4 to which the reinforcing tool 5 is attached is fitted into the runner 3, the outer width L1 and the opening width L2 (FIG. 3) of the stud 4 are smaller than the outer width L21 and the opening width L22 before installation, respectively. , Equal to the prescribed outer width and opening width.

  As described above, the reinforcing tool 5 in the present embodiment allows a slight reduction deformation in the width direction of the stud 4 when fitted into the runner 3. Therefore, the upper end portion of the stud 4 to which the reinforcing tool 5 is attached can be easily fitted into the runner 3 without applying a special force. Similarly, the lower end of the stud 4 can be easily fitted into the lower runner 2.

(Regarding the function of the reinforcing tool under load)
The function of the reinforcing tool 5 when a load in the out-of-plane direction is applied to the partition wall W as shown in FIG. 1 and a large force is applied to one side surface of the stud 4 from the outside as shown in FIG. . As described above, the reinforcing member 5 is attached only to the upper end portion and the lower end portion of the stud 4 (that is, only to the portion fitted in the runners 3 and 2).

  In a normal state, the boundary portion 55 of the reinforcing tool 5 is disposed on the end surface of the edge portion 43 of the stud 4 in a face-to-face state. Therefore, even if a large force is applied to one side surface of the stud 4, the end surface of the edge portion 43 abuts against the boundary portion 55, so that the interval (opening width) between the pair of edge portions 43 is set to the pair of boundary portions 55. It is prevented from becoming smaller than the space | interval L12 of the outer side surface. That is, the interval between the pair of edge portions 43 is prevented from being less than the predetermined opening width dimension (L2).

  Further, since the edge portion 43 of the stud 4 is sandwiched between the back surface of the front side plate-like portions 52 and 53 and the surface of the back side plate-like portion 54 which are parallel to each other, a pair of edges are prevented while preventing the edge portion 43 itself from being deformed. The part 43 can be stretched.

  Thus, the reinforcing tool 5 does not restrict the deformation of the stud 4 in the direction in which the distance between the edge portions 43 increases, and restricts the deformation of the stud 4 only in the direction in which the distance between the edge portions 43 decreases. Therefore, according to the reinforcing tool 5 of the present embodiment, when the stud 4 is fitted into the runner 3 as described above, a slight reduction deformation of the stud 4 is allowed. It is possible to prevent the distance from shrinking beyond an allowable value. As a result, it is possible to prevent the stud 4 from being reduced and deformed so that the outer width L1 becomes less than the predetermined outer width dimension when loaded.

  Further, in the installed state of the stud 4, the stud 4 can be prevented from being deformed in the width direction by the reinforcing tool 5, so that the fitting state between the stud 4 and the runners 2 and 3 can be maintained even when loaded. Can do. Therefore, the separation from the runners 2 and 3 due to the rotation of the stud 4 in the runners 2 and 3 can be prevented. As a result, even if the stud 4 made of C-type steel is used as the pillar material of the partition wall W, the strength of the partition wall W can be improved.

  In addition, since the pair of boundary portions 55 are positioned in the same height range in the attached state of the reinforcing tool 5, the pair of edge portions 43 of the stud 4 can be stretched in a balanced state by the pair of boundary portions 55. Thereby, rotation of reinforcing tool 5 itself at the time of load can be prevented. Therefore, even if the reinforcing tool 5 is not completely fixed to the stud 4 with a screw or the like, the distance between the pair of edge portions 43 can be appropriately maintained even during loading.

  Further, in the present embodiment, since the boundary portion 55 intersects the main body portion 51 at a substantially right angle, even if the outer surface of the boundary portion 55 is pushed inwardly by the end surface of the edge portion 43. The deformation of the edge 43 can be prevented or suppressed.

  Even if a large load is applied to the partition wall W and the stud 4 is somewhat twisted, the distance D12 between the front plate portions 52 and 53 and the back plate portion 54 is the thickness of the edge portion 43. Since it is smaller than (plate thickness dimension D1 of the stud 4), the reinforcing tool 5 cannot be easily detached from the edge portion 43. Therefore, even if the reinforcing tool 5 is somewhat slipped off due to the twist of the stud 4, the reinforcing tool 5 can be kept at a shifted position. Therefore, according to the present embodiment, it is possible to prevent or suppress the stud 4 from falling off the runners 2 and 3 and the face material 80 from falling off due to the twist of the stud 4.

From this, the structure of the partition wall W can be adopted for the partition wall of a warehouse requiring high load resistance. That is, the partition wall W in the present embodiment can withstand the strength defined by the warehouse business law, that is, a load of 2500 N / m ² or more.

  Moreover, in this Embodiment, since the reinforcement tool 5 is formed by processing one thin plate, the manufacturing cost of the reinforcement tool 5 can be suppressed low.

  In addition, in this Embodiment, although the reinforcement tool 5 showed the example attached so that the main-body part 51 might be located in the surface side of the edge part 43, the main-body part 51 is located in the back surface side of the edge part 43. As shown, it may be attached upside down. In this case, the above-described front side plate-like portions 52 and 53 may be read as the back-side plate-like portion, and the back-side plate-like portion 54 may be read as the front-side plate-like portion.

  Moreover, the structure of the reinforcing tool attached between the edge parts 43 of the stud 4 is not limited to the above structure. Below, the other structural example of a reinforcement tool is demonstrated as a modification of this Embodiment.

(Modification 1)
FIG. 8 is a plan view schematically showing a reinforcing tool 5A in Modification 1 of the present embodiment. FIG. 9 is a cross-sectional view of the reinforcing tool 5A cut along the line IX-IX in FIG.

  As shown in FIGS. 8 and 9, the reinforcing tool 5A is formed by welding two thin plates. In this modification, two thin plates having substantially the same size and shape are stacked and welded in the plate thickness direction. The thin plate on the front side is flat without a step from one end in the width direction to the other end. On the other hand, the thin plate on the back side is bent in a substantially L shape in a direction in which both end portions in the width direction are separated from the thin plate on the front side.

  In this case, the portion where the two thin plates overlap constitute the main body 51A. Specifically, the main body 51 </ b> A includes a front thin plate disposed at a position closer to the front surface than the edge 43 of the stud 4, and a back thin plate disposed at the same front and back direction position as the edge 43 of the stud 4. Consists of.

  Moreover, the part located in the both sides of the main-body part 51 comprises the front side plate-shaped part 52A among the front side thin plates, and is parallel to the front side plate-like part 52A among the back side thin plates, and away from the front side plate-like part 52A. The portion located constitutes the back side plate-like portion 54A. The pair of boundary portions 55 is formed between the back side plate-like portion 54A and the main body portion 51A in the back side thin plate. Each front side plate-like portion 52A has at least one convex portion 56 on the back surface side.

The size and shape of the reinforcing tool 5C in plan view are substantially the same as the reinforcing tool 5 of the above embodiment. The reinforcing tool 5C is also formed of a single thin plate, like the reinforcing tool 5.

  The reinforcing tool 5 of the above embodiment has two pairs of front side plate-like parts 52, 53 and a pair of back side plate-like parts 54. However, the reinforcing tool 5C has a pair of front side plate-like parts 52 and And two pairs of back side plate-like portions 54. Therefore, in this modification, two pairs of boundary portions 55 are formed. When the load is applied to the side portion of the stud 4, the reinforcing tool 5 </ b> C has a larger area than the reinforcing tool 5 because the area of the portion that contacts the end face of the edge portion 43 of the stud 4 (that is, the boundary portion 55) increases. Reduction deformation of the stud 4 can be effectively prevented.

  Also in this modification, each front side plate-like part 52 has one convex part 56 on the back side, but in this modification, only one is displayed on both sides of the main body part 51. There is no side plate-like portion 52. Therefore, each front side plate-like portion 52 desirably has a plurality of convex portions 56 on the back surface side. It is desirable that the plurality of convex portions 56 be provided at intervals in the vertical direction. Thereby, sliding-down of the reinforcing tool 5C can be prevented.

  Alternatively, in this modified example, in addition to / in place of the convex portion 56 of the front side plate-like portion 52, the back side plate-like portion 54 that exists two on each side of the main body portion 51 has one convex portion on the front side. You may have. Similarly, in the reinforcing members of the above-described embodiment and modifications 1 and 2, the back-side plate-like portion 54 may have a convex portion.
