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.

Square steel with a closed cross section and C-shaped steel (channel steel) with an open cross section having an opening on one side are used as pillar materials (studs) for the walls of buildings that employ lightweight steel frames.

For example, as a pillar material for a parting wall separating dwelling units, a substantially grooved stud is used 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). 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 walls that require relatively high strength, such as outer walls and partition walls of warehouses, square steel is generally used as a pillar material.

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

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

However, since such a C-shaped stud is less strong than a square stud, when a high out-of-plane load is applied to the C-shaped stud, the stud rotates in the upper and lower runners due to torsion. and may fall off the runner. Therefore, it is difficult to employ a C-shaped stud as it is (individually) as a column material for a wall that requires strength.

In addition, as shown in Patent Documents 1 and 2, studs in which a plurality of spacers are fitted are sometimes used as pillar materials for houses, etc. However, simply fitting conventional spacers into C-shaped steel will not increase the strength of the wall. cannot be sufficiently improved.

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

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

(Regarding the schematic structure of the wall structure)
A schematic configuration of a wall structure 1 according to the present embodiment will be described with reference to FIGS. 1 and 2. FIG. The wall structure 1 is the structure of a partition wall (partition wall) W that partitions two adjacent spaces in a building. Note that the virtual plane 90 shown in FIGS. 1 and 2 is a partition plane that separates two adjacent spaces. 1 and 2, the vertical direction (vertical direction) of the partition surface 90 is indicated by arrow A1, and the horizontal direction (horizontal direction) of the partition surface 90 is indicated by arrow A2. Further, in FIG. 2, the direction perpendicular 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. As shown in FIG.

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

The runner 2 is positioned at the lower end of the partition wall W, and the runner 3 is positioned 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 runners 2 and 3 coincides with the direction orthogonal to partition surface 90 .

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

Each stud 4 has a substantially rectangular (rectangular) cross section, and its upper end and lower end are fitted in a pair of runners 3 and 2, respectively. The stud 4 is C-shaped steel and includes an open face 40 , a closed face 41 facing the open face 40 , and a pair of side faces 42 perpendicular to the open face 40 and the closed face 41 . The width dimension of the open surface portion 40 and the closed surface portion 41 is longer than the width dimension of the side surface portion 42 . The open surface portion 40 is composed of a pair of edge portions 43 , and an opening 44 extending vertically is formed between the edge portions 43 .

The stud 4 is rigidly arranged so that the closed surface portion 41 and the open surface portion 40 are aligned in a direction orthogonal to the partition surface 90 (out-of-plane direction). In this case, a face member 80 ( FIG. 1 ) is fixed to the side portion 42 of the stud 4 . Face material 80 is, for example, a gypsum board. In the following description, the state in which the upper end and the lower end of the stud 4 are fitted into the runners 3 and 2 respectively is referred to as the installed state of the stud 4 .

As the stud 4, C-shaped steel, which is generally distributed, is adopted, and the prescribed outer width dimension (the prescribed width dimension of the closing surface portion 41) is, for example, 100 mm. In this case, the distance between the flange portions 22, 32 of the runners 2, 3 is also 100 mm, for example. The prescribed width dimension of the opening 44 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 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 less expensive than, for example, square steel with a plate thickness of 1.2 mm, the cost of the partition wall W can be reduced compared to using square steel as a column material.

On the other hand, the out-of-plane load bearing capacity of such a C-shaped stud 4 is lower than that of square steel. In other words, when a high load is applied to the stud 4 in the out-of-plane direction, the stud 4 normally rotates within the upper and lower runners 2 and 3 due to twisting, and there is a risk of falling off the runners 2 and 3. . Here, in order to prevent the studs 4 from rotating within the runners 2 and 3, the plate thickness of the runners 2 and 3 is increased to prevent the runners 2 and 3 from being pushed by the stud 4 to open. is also conceivable. However, in that case, the cost of the runners 2 and 3 increases, which is not desirable in order to suppress the cost increase of the partition wall W.

Therefore, in the present embodiment, one reinforcing member 5 is attached to each of the lower end and upper end of each stud 4 (that is, the portion to be fitted into the runners 2 and 3). That is, the reinforcing member 5 attached to the upper end of the stud 4 is arranged above the height of the lower end of the flange portion 32 of the runner 3 , and the reinforcing member 5 attached to the lower end of the stud 4 is located above the flange portion 22 of the runner 2 . is placed below the height of the top edge of the

The reinforcing member 5 in this embodiment is characterized by including at least a pair of runner contact portions 60 located outside the pair of edge portions 43 of the stud 4 . Taking the reinforcement member 5 attached to the upper runner 3 as an example, the runner contact portions 60 contact the pair of flange portions 32 of the runner 3 respectively. As a result, the contact area with the flange portion 32 increases compared to when only the side portion 42 of the stud 4 contacts the flange portion 32, so the strength of the stud 4 in the out-of-plane direction can be improved.

(Regarding configuration examples of reinforcing tools)
A configuration example of the reinforcing member 5 will be described with reference to FIGS. 3 to 6. FIG. FIG. 3 is a perspective view of the reinforcing member 5. FIG. FIG. 4 is an enlarged view of the region IV shown in FIG. 2, and is a perspective view showing a state in which the stiffener 5 is attached to the upper end of the stud 4. As shown in FIG. FIG. 5 is a cross-sectional view showing the same state, and FIG. 6 is a side view showing the same state. 4, illustration of the runner 3 is omitted.

The stiffener 5 includes an attachment portion 50 attached to the stud 4 and at least a pair of runner contact portions 60 integrally connected with the attachment portion 50 . The reinforcing member 5 is formed, for example, by processing a sheet of metal thin plate. The stiffener 5 is typically configured to be bilaterally symmetrical. The width direction (horizontal direction) of the reinforcing member 5 is the same as the width direction of the runner 3 .

The mounting portion 50 includes, for example, a body portion 51 located between the pair of edge portions 43 of the stud 4 and two pairs of two pairs of body portions 51 connected to both widthwise end portions of the body portion 51 and arranged along the surfaces of the edge portions 43 . It includes front side plate-like portions 52 and 53 and a pair of back side plate-like portions 54 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 . The front side plate-like portions 52 and 53 and the back side plate-like portion 54 constitute a sandwiching portion that sandwiches the edge portion 43 . The body portion 51 has a function of connecting the holding portions arranged on one side and the other side in the width direction.

It is desirable that the front side plate-like portions 52 and 53 have convex portions 56 as projections on the back side. As a result, frictional resistance is generated between the edge portion 43 of the stud 4 and the convex portion 56, so that the reinforcing member 5 can be prevented from dropping by its own weight without using fixing means such as screws. In other words, the mounting portion 50 is held on the stud 4 by the frictional force in the clamping portion. In addition, a convex portion may be provided on the surface side of the back side plate-like portion 54 . Alternatively, the convex portion 56 is not essential, and the reinforcing member 5 may be attached and held to the stud 4 by the frictional resistance between the contact surfaces of the clamping portion and the edge portion 43 .

As shown in FIG. 3 , the pair of front side plate-shaped portions 52 are located above the pair of back side plate-shaped portions 54 , and the other pair of front side plate-shaped portions 53 are located above the pair of back side plate-shaped portions 54 . is also located below. The main body portion 51 is located outside the edge portion 43 of the stud 4 and formed flush with the front side plate portions 52 and 53 . Therefore, a boundary portion 55 is interposed between the main body portion 51 and each rear plate-like portion 54 . Note that the front side plate-like portions 52 and 53 and the back side plate-like portion 54 may be provided so as to overlap in the height direction.

A space L11 between the outer surfaces of the two boundary portions 55 is determined to substantially match the prescribed opening width dimension (L2) of the stud 4 . Therefore, in the installed state of the stud 4 , the outer surface of the boundary portion 55 is in contact (surface contact or line contact) with the end surface of the edge portion 43 . As a result, when a load is applied to the stud 4 in the out-of-plane direction in the installed state, it is possible to prevent the stud 4 from deforming in a direction in which the distance between the pair of edge portions 43 is reduced.

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 depending on the processing accuracy of the stud 4 and the like. That is, when the stud 4 is installed, if the boundary portion 55 faces the end surface of the edge portion 43 of the stud 4 , the outer surface of the boundary portion 55 is close to the end surface of the edge portion 43 without being in contact with the edge portion 43 . may be

In the present embodiment, the front side plate-like portions 52 and 53 extend laterally from the main body portion 51 , and the lateral ends are in contact with or close to the flange portion 32 of the runner 3 . That is, the width dimension of each of the front side plate-like portions 52 and 53 is substantially equal to the width dimension of each edge portion 43 of the stud 4 . Therefore, the width dimension L11 of the front side plate-shaped portions 52, 52 (53, 53) formed flush with each other in the mounting portion 50 and the main body portion 51 together is substantially the same as the outer diameter dimension L1 in the width direction of the stud 4. is.

The two pairs of runner contact portions 60 are composed of runner contact portions 61, 61 located relatively upward and runner contact portions 62, 62 located relatively downward. The runner contact portions 61 and 62 are arranged to cross the side ends of the front plate-like portions 52 and 53, respectively. That is, the runner contact portions 61 and 62 each extend along the longitudinal direction of the runner 3 outside the stud 4 . In the present embodiment, the side surface portion 42 of the stud 4 and the runner contact portions 61 and 62 are arranged adjacent or close to each other in the longitudinal direction of the runner 3 .

In addition, in FIG. 5, the direction away from the stud 4 is indicated by an arrow A4. In the description of the runner contact portions 61 and 62, the arrow A4 direction is called the outside, and the opposite direction is called the near side.

Specifically, the front end portions of the upper runner contact portions 61, 61 are integrally connected to the side end portions of the front plate-like portions 52, 52. As shown in FIG. Therefore, as shown in FIG. 5, the runner contact portions 61, 61, and the front side plate-like portions 52, 52 and the main body portion 51 formed flush with each other in the mounting portion 50 form a substantially U-shape when viewed from above. arranged in a shape. In this case, the front side plate-like portion 52 and the main body portion 51 of the mounting portion 50 function as a space retaining portion that retains the space between the runner contact portions 61 , 61 . The runner contact portions 61 , 61 face each other at the same height and are in surface contact with each of the pair of flange portions 32 of the runner 3 . As shown in FIG. 6, the runner contact portions 61, 61 are in surface contact with the base end region 32a of the flange portion 32 of the runner 3 near the base end (upper end).

The front end portions of the runner contact portions 62, 62 located on the lower side are integrally connected to the side end portions of the front plate-shaped portions 53, 53. As shown in FIG. Therefore, similarly to the above, the runner contact portions 62, 62, the front side plate-like portions 53, 53 formed flush with each other in the mounting portion 50, and the main body portion 51 are arranged in a substantially U shape when viewed from above. It is In this case, the front side plate-like portion 53 and the main body portion 51 of the mounting portion 50 function as a space holding portion that holds the space between the runner contact portions 62 , 62 . The runner contact portions 62 , 62 face each other at the same height and are in surface contact with each of the pair of flange portions 32 of the runner 3 . As shown in FIG. 6 , the runner contact portions 62 , 62 are in surface contact with the distal end side region 32 b of the flange portion 32 of the runner 3 near the distal end (lower end).

It is desirable that curved portions 61 a and 62 a that are curved in an R shape in a direction away from the flange portion 32 of the runner 3 are provided at the tip portions (outer end portions) of the runner contact portions 61 and 62 , respectively. The curved portion 61 a functions as a guiding portion when the stud 4 to which the reinforcing member 5 is attached is fitted into the runner 3 .

(About construction method of partition wall)
Next, a method for constructing the partition wall W will be briefly described. In this embodiment, the construction method of the partition wall W includes a step P1 of arranging the pair of runners 2 and 3, a step P2 of preparing the reinforcing member 5, and attaching the reinforcing member 5 to the upper end portion and the lower end portion of the stud 4, respectively. Step P3 includes a step P4 of fitting the upper and lower ends of the stud 4 to which the reinforcing member 5 is attached to the runners 3 and 2, respectively. It should be noted that the execution order of the process P1 and the processes P2 and P3 may be reversed.

In step P3, as shown in FIG. 7, the reinforcing member 5 is inserted (struck) into the edge 43 of the stud 4 from the vertical edge of the stud 4 while standing vertically. In addition, in FIG. 7, illustration of the curved portions 61a and 62a is omitted.

At this time, the reinforcing member 5 can be slid along the longitudinal direction of the stud 4 while the edge portion 43 is sandwiched between the lower front plate-like portion 53 and the lower back plate-like portion 54 . Since the front side plate-like portions 52 and 53 of the reinforcing member 5 have the protrusions 56 on the back side, the reinforcing member 5 can be temporarily fixed to the stud 4 at a desired position. Therefore, the insertion of the reinforcing member 5 can be easily performed.

In step P4, the lower end of the stud 4 is fitted into the runner 2, and then the upper end of the stud 4 is fitted into the runner 3. As shown in FIG. When fitting the lower end of the stud 4 into the runner 2 , for example, the stud 4 is slightly slanted and fitted into the runner 2 from the closing surface portion 41 side. In this case, the upper end portion of the stud 4 is fitted into the runner 3 from the open surface portion 40 side. In this embodiment, as described above, the curved portions 61a and 61b are provided at the distal ends of the runner contact portions 61 and 62, respectively. Therefore, even if the runner contact portions 61 and 62 protruding outward from the stud 4 are attached to the upper end portion of the stud 4 , the curved portions 61 a and 61 b at the tips of the runner contact portions 61 and 62 are the flange portions of the runner 3 . 32 first, the upper end of the stud 4 can be smoothly fitted into the runner 3. - 特許庁

(Regarding the function of the reinforcement under load)
The function of the reinforcing member 5 when an out-of-plane load is applied to the partition wall W as shown in FIG. 1 and a large force is applied from the outside to one side surface of the stud 4 as shown in FIG. 5 will be described. . As described above, the stiffeners 5 are attached only to the upper and lower ends of the studs 4 (that is, only to the portions fitted into the runners 3, 2).

If the stud 4 is used as a pillar material for the wall of a house, a large load is not applied, but if the stud 4 is used as a pillar material for the wall of a warehouse, a large load may be applied to the side of the stud 4. be. When a large force is applied to the side surface of the stud 4, the stud 4 is twisted. When the stud is square steel, the shear center is located inside the stud 4 (internal space). To position. Therefore, the stud 4 is more likely to be twisted than square steel.

In this embodiment, stiffeners 5 having two pairs of runner contact portions 61 and 62 are attached to the upper and lower ends of stud 4 . Therefore, when a load is applied to one side surface of the stud 4, the load is transferred to the side portion 42 of the stud 4 and the runner contact portions 61 and 62 arranged continuously (adjacent or close to) the side portion 42. can be received on both sides. Specifically, since the gap between the two pairs of runner contact parts 61 and 62 is held by the gap holding parts (body part 51 and front side plate-like parts 52 and 53), the out-of-plane Can withstand directional loads. Therefore, according to the present embodiment, the torsional force generated in the stud 4 can be counteracted with a small force. As a result, it is possible to prevent the stud 4 from rotating within the runner 3 while the runner 3 is open.

Moreover, since it is possible to prevent the runner 3 from being opened in this manner, the plate thickness of the runner 3 does not need to be increased. Therefore, an increase in cost of the runner 3 can be suppressed.

In this embodiment, the reinforcing member 5 is attached to both the upper end portion and the lower end portion of the stud 4, but it may be attached to at least one of them.

In addition, although the reinforcing member 5 is composed of two pairs of runner contact portions 60 (61, 62), only one pair of runner contact portions may be provided. In this case, in order to prevent the flange portion 32 of the runner 3 from opening when receiving a load in the out-of-plane direction, the reinforcing member 5 is provided in the base end region 32a of the flange portion 32 of the runner 3. It is desirable to include a runner contact portion 61 for surface contact.

Also, the configuration of the runner contact portion 60 or the configuration of the mounting portion 50 is not limited to the above examples. Another configuration example of the reinforcing member will be described below as a modified example of the present embodiment. In addition, in the modified example, only the difference from the reinforcing member 5 will be described in detail.

(Modification 1)
A configuration example of a reinforcing member 5A according to Modification 1 of the present embodiment will be described with reference to FIGS. 8 to 10. FIG. FIG. 8 is a perspective view of the reinforcing tool 5A. FIG. 9 is a cross-sectional view showing a state in which a reinforcing member 5A is attached to the upper end of the stud 4. FIG. FIG. 10 is a side view showing the same state.

The reinforcing member 5A includes an attachment portion 50A and a pair of runner contact portions 63 instead of the attachment portion 50 and the two pairs of runner contact portions 61 and 62 described above.

The structure of the attachment portion 50A is basically the same as that of the attachment portion 50 in the above embodiment, but the front and back directions are reversed. That is, the mounting portion 50A is connected to the main body portion 51 positioned between the pair of edge portions 43 of the stud 4, and to both ends of the main body portion 51 in the width direction, and is arranged along the back surface of the edge portion 43. It includes portions 52A and 53A, and a pair of front side plate-like portions 54A that are connected to both ends in the width direction of the body portion 51 and arranged along the surface of the edge portion 43 . In this case, for example, convex portions 56 are provided on the surface sides of the back surface plate portions 52A and 53A.

The body portion 51 is located inside the edge portion 43 of the stud 4 and is formed flush with the back side plate portions 52A and 53A. A boundary portion 55 is interposed.

The pair of runner contact portions 63 have front end portions that intersect (intersect) each of the front side plate-like portions 54A. Also in this case, as shown in FIG. 10 , it is desirable that at least a portion of the runner contact portion 63 is in surface contact with the base end region 32a of the flange portion 32 of the runner 3 .

In this modified example, the distance between the runner contact portions 63 , 63 is maintained by the front plate-like portions 54</b>A, 54</b>A, the boundary portion 55 and the main body portion 51 . In this way, the interval holding portion may be configured by a portion having a slight step.

(Modification 2)
A configuration example of a reinforcing member 5B according to Modification 2 of the present embodiment will be described with reference to FIGS. 11 to 13. FIG. FIG. 11 is a perspective view of the reinforcing tool 5B. FIG. 12 is a transverse cross-sectional view showing a state in which the stiffener 5B is attached to the upper end of the stud 4. As shown in FIG. FIG. 13 is a side view showing the same state.

The reinforcing member 5B has the mounting portion 50 shown in the above embodiment, but has a pair of runner contact portions 64 instead of the two pairs of runner contact portions 61 and 62 . The reinforcing member 5B further includes an extension portion 65 extending outward from the upper edge of the mounting portion 50, and the pair of runner contact portions 64 are integrally connected to both ends of the extension portion 65 in the width direction.

The extension portion 65 is orthogonal to (intersects) the main body portion 51 and the upper front plate portion 52 of the attachment portion 50 and is arranged substantially parallel to the top surface portion 31 of the runner 3 . The width dimension of the extended portion 65 is substantially the same as the outer diameter dimension L1 of the stud 4 in the width direction.

The runner contact portion 64 is formed by bending downward (or upward) the width direction end portion of the extended portion 65 . Therefore, the runner contact portions 64, 64 and the extension portion 65 are arranged in a substantially U shape when viewed from the front (outside). In this modified example, the distance between the runner contact portions 64 , 64 is maintained by the extended portion 65 . In the above example, a part of the mounting portion 50 constitutes the space holding portion, but the space holding portion (extended portion 65) may be provided separately from the mounting portion 50 in this manner.

In addition, it is desirable that the boundary portion between the extension portion 65 and the runner contact portion 64 has a smoothly curved shape (R shape). Further, in consideration of ease of fitting the stud 4 into the runner 3, the distal end portion (outer end portion) of the extended portion 65 may also be provided with a curved portion.

Further, in this modified example, as shown in FIGS. 12 and 13, a slight gap may be provided between the side surface portion 32 of the stud 3 and the runner contact portion 64 .

(Modification 3)
A configuration example of a reinforcing member 5C according to Modification 3 of the present embodiment will be described with reference to FIGS. 14 to 17. FIG. FIG. 14 is a perspective view of the reinforcing tool 5C. FIG. 15 is a perspective view showing a state in which the stiffener 5C is attached to the upper end of the stud 4. FIG. FIG. 16 is a cross-sectional view showing the same state, and FIG. 17 is a side view showing the same state. Note that illustration of the runner 3 is omitted in FIG. 15 .

The reinforcing member 5C includes an attachment portion 50B and a pair of runner contact portions 66 instead of the attachment portion 50 and the runner contact portions 61 and 62 described above. As in the second modification, the runner contact portion 66 is integrally connected to the width direction end portion of the extension portion 67 extending outward from the mounting portion 50B.

The mounting portion 50B includes a plate-like main body portion 51A that is fitted in the internal space of the stud 4 in a perpendicular state, and a plurality of rising portions 57 that are integrally connected to the main body portion 51A. The planar shape of the main body portion 51A is substantially rectangular, and the four sides of the main body portion 51A come into contact with the closing surface portion 41, the pair of edge portions 43, and the pair of side surface portions 42 inside the stud 4. As shown in FIG.

Rising portions 57 are desirably provided on the long side that contacts the closing surface portion 41 and on each short side that contacts the side surface portion 42 . As a result, even in this modified example, the reinforcing member 5 can be attached and held to the stud 4 by the frictional resistance between the contact surfaces without separately providing fixing means such as screws.

In order to more reliably prevent the reinforcing member 5C from falling, the above-described convex portion (not shown) may be provided on the rear surface of the rising portion 57 (the surface that contacts the stud 4). Alternatively, the angle between the rising portion 57 of the mounting portion 50B and the main body portion 51A may be an obtuse angle so that the rising portion 57 may function as a leaf spring.

The extended portion 67 is provided so as to be continuous with the body portion 51 in a flush manner. Since the boundary portion 58 between the main body portion 51 and the extended portion 67 is positioned between the pair of edge portions 43 of the stud 4, the edge portion 43 is sandwiched between the main body portion 51 and the extended portion 67 in the front-back direction. is Therefore, in this modified example, part of the main body part 51 and part of the extension part 67 constitute a sandwiching part that sandwiches the edge part 43 .

The runner contact portion 66 is formed by bending upward the width direction end portion of the extended portion 67 . In this modified example, the distance between the runner contact portions 66 , 66 is maintained by the extended portion 67 .

A curved portion 66 a is desirably provided at the upper end portion of the runner contact portion 66 . A curved portion may also be provided at the outer end portion of the runner contact portion 66 .

18, the runner contact portion 66 may be formed by bending the width direction end portion of the extended portion 67 downward. That is, the rising portion 57 and the runner contact portion 66 may be provided in opposite directions in the vertical direction.

(Other modifications)
Although the above-mentioned runner contact portion has been described as being in surface contact with the flange portion 32 of the runner 3, it may be in line contact or point contact as long as it is in contact with the flange portion 32, for example.

All of the mounting portions shown in the above embodiment and modifications are mounted on the stud 4 by frictional force, but this is not a limitation. For example, the attachment portion may be configured by a hook portion that is hooked on the edge portion 43 of the stud 4 . Alternatively, the attachment portion may be attached to the stud 4 by fixing the portion that comes into surface contact with the stud 4 with a fixing means such as a screw or an adhesive.

Although the wall structure 1 described above has been described as a structure suitable for the partition wall W of a warehouse, it is not limited. For example, it may be an outer wall of a warehouse or a wall structure of a building other than a warehouse.

It should be considered that the embodiments disclosed this time are illustrative in all respects and not restrictive. The scope of the present invention is indicated by the scope of the claims rather than the above description, and is intended to include all modifications within the meaning and range of equivalents of the scope of the claims.
