Description

[Technical Field]

[0001] The present invention relates to a wall structure. [Background technology]

[0002] A known partition wall structure is one in which wall panels are attached to a wall base that includes a pair of upper and lower runner members, a number of studs that engage with the upper and lower runner members, and vibration-proof members that are suspended across the spaced-apart studs. The wall panels are fastened to the studs with screws.

[0003] To use such a wall base for a recessed wall, the stud material is fixed to a base wall such as a concrete skeleton wall using a position-adjustable connecting metal fitting (see, for example, Patent Document 1). Specifically, as shown in Patent Document 1, the connecting metal fitting is L-shaped in plan view, with one side fixed to the base wall and the other side fixed to the side of the stud material. The shape of the connecting metal fitting is not limited to an L-shape, and some have a groove-shaped cross section. Another construction method involves using a urethane foam adhesive to secure the studs to the base wall at a specified distance. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 5-10631 Summary of the Invention [Problem to be solved by the invention]

[0005] When studs are erected independently using conventional methods, the floor plan becomes larger, resulting in a smaller room. On the other hand, reducing the floor plan reduces the strength and rigidity of the studs, making reinforcement necessary. In the conventional stud wall described above, the distance between each stud and the base wall is adjusted using connecting metal fittings, which creates the problem of requiring a lot of time and effort for construction. Furthermore, the method of fixing studs using adhesives creates the problem of not being able to clearly determine the fixing strength of the wall. Furthermore, because studs are long, extending from the floor to the ceiling, there is the problem of them being difficult to transport using an elevator, for example, when renovating an apartment building.

[0006] From this perspective, the present invention aims to provide a wall structure that has high fixing strength of the wall base, reduces the construction effort and time required for position adjustment, and allows materials to be easily transported. [Means for solving the problem]

[0007] To solve the above problems, the present invention provides a wall structure in which a wall base is installed with a gap in the base, the wall base comprising stud members extending vertically and divided into at least two pieces, and a connecting member connecting the upper and lower stud members. The connecting member comprises a main body extending horizontally along the surface of the base, an upper support member supporting a plurality of the upper stud members, a lower support member supporting a plurality of the lower stud members, and an adjustment means for adjusting the projection dimension of the main body relative to the base.

[0008] According to the wall structure of the present invention, the position of the studs relative to the base can be appropriately determined by adjusting the inward / outward dimensions of the connecting members, which reduces the construction effort and time required for position adjustment compared to conventional techniques in which the position of each stud had to be adjusted individually. Furthermore, the studs can be secured with the necessary fixing strength by being fixed to the upper and lower supports. Furthermore, because the studs are divided into upper and lower halves, their length is shortened, making them easier to handle and transport by elevator, etc.

[0009] In the wall structure of the present invention, the inward / outward movement adjustment means preferably includes a screw member extending from the main body portion to the base portion and a rotating member abutting the main body portion and threadedly engaging with the screw member, and the rotating member rotates to move in the axial direction of the screw member and advance / retreat relative to the base portion, thereby moving the main body portion. With this configuration, the inward / outward movement dimension of the connecting member can be easily adjusted by rotating the rotating member.

[0010] In the wall structure of the present invention, the rotating member is preferably disposed closer to the base member than the main body and protrudes from the main body, allowing an operator to easily rotate the rotating member by grasping the protruding portion of the rotating member.

[0011] Furthermore, in the wall structure of the present invention, the main body comprises a first member having a hat-shaped cross section with upper and lower flanges and a second member installed on the base side of the first member, and the upper support portion is preferably formed in a groove shape that opens upward between the upper flange and the second member, and the lower support portion is preferably formed in a groove shape that opens downward between the lower flange and the second member. This configuration increases the strength of the main body and allows the ends of studs to be inserted into the upper and lower support portions and easily fixed with screws or the like.

[0012] In the wall structure of the present invention, the first member preferably has a groove-shaped portion between the upper and lower flanges that opens toward the side opposite the base member, the screw member is disposed to penetrate the groove-shaped portion and the second member, and the first member and the second member are clamped by a nut and the rotating member disposed in the groove-shaped portion. This configuration allows the first member, second member, and rotating member to be integrated by the screw member, facilitating assembly and reducing the number of parts. Furthermore, because the tip of the screw member is disposed within the groove-shaped portion, the screw member does not interfere with the surface material attached to the wall base. [Effects of the Invention]

[0013] According to the wall structure of the present invention, the fixing strength of the wall base is increased, the construction labor and construction time for position adjustment can be reduced, and materials can be easily transported. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0015] A wall structure according to an embodiment of the present invention will be described in detail with reference to the drawings. In this embodiment, a wall structure will be described using a reinforced concrete structural body wall as a base. The wall structure according to this embodiment is constructed as a partition wall installed indoors. As shown in Figures 1 to 4, the wall structure 1 has a wall base 3 installed on a base 2 with a gap therebetween, and a plate-shaped wall material (not shown) laid on the surface of the wall base.

[0016] The wall base 3 is a portion attached to the base portion 2. The base portion 2 is formed in a planar shape and is composed of, for example, a structural body wall or a partition wall made of reinforced concrete. The wall base 3 includes a stud material 10 and a connecting member 20.

[0017] The stud material 10 is a member that extends vertically and is made of a square pipe made of lightweight steel. The stud material 10 is divided into at least two pieces (two in this embodiment). The stud material 10 is divided in the middle in the height direction. When distinguishing between the two upper and lower stud materials 10, they are called the upper stud material 10a and the lower stud material 10b.

[0018] As shown in Figures 1, 3, and 4, the upper end of the upper stud member 10a is fixed to a runner member 11 arranged on the ceiling. The runner member 11 is made of lightweight channel steel with a U-shaped cross section and is laid, for example, along the underside of the floor slab 4 of the upper floor. The lower end of the lower stud member 10b is fixed to a runner member 11 arranged on the floor. The runner member 11 is made of lightweight channel steel with a U-shaped cross section and is laid, for example, along the upper surface of the floor slab 5. The upper runner member 11 is arranged so that the groove opening faces downward, and the lower runner member 11 is arranged so that the groove opening faces upward. Of the vertical plate portions of the runner member 11 (a pair of plate portions forming the sides of the groove), the vertical plate portion on the front side (indoor side) is shorter in height than the vertical plate portion on the back side (substrate 2 side). The upper and lower stud members 10 are arranged with a predetermined gap between them, and a connecting member 20 is interposed between the upper and lower stud members 10.

[0019] The connecting member 20 connects the upper and lower divided stud members 10. The connecting member 20 comprises a main body 21, an upper support portion 22, a lower support portion 23, and an inward / outward movement adjustment means 24.

[0020] The main body 21 is disposed at a predetermined distance from the surface of the base 2 and extends laterally along the base 2. As shown in FIGS. 5 to 8, the main body 21 comprises a first member 25 and a second member 26. The first member 25 has a hat-shaped cross section and includes a groove-shaped portion 27 and flanges 28, 28 provided at both widthwise ends thereof. The first member 25 has flanges 28, 28 located above and below the groove-shaped portion 27, and is disposed vertically so that the groove-shaped portion 27 opens toward the interior side (the side opposite the base 2). The first member 25 extends laterally. A screw insertion hole 29 (see FIGS. 3 and 6) is formed at the bottom of the groove-shaped portion 27. The screw insertion hole 29 is a hole through which the rod screw 33 of the screw member 31 of the entry / exit adjustment means 24 is inserted, and is configured as a horizontally elongated hole.

[0021] The second member 26 is a member that is installed on the base portion 2 side of the first member 25. The second member 26 has a groove shape and is arranged vertically so that it opens on the base portion 2 side. The second member 26 extends in the horizontal direction and has the same length dimension as the first member 25. A screw insertion hole 30 (see Figure 6) is formed at the bottom of the groove of the second member 26. The screw insertion hole 30 is a hole through which the rod screw 33 of the screw member 31 of the entry / exit adjustment means 24 is inserted, and is configured as an elongated hole that is the same shape as the screw insertion hole 29 and is long in the horizontal direction.

[0022] When the first member 25 and the second member 26 are combined, an upper support portion 22 is formed on the upper part of the main body portion 21, and a lower support portion 23 is formed on the lower part of the main body portion 21. The upper support portion 22 is a portion that supports a plurality of upper studs 10 (upper studs 10a), and is formed in a groove shape that opens upward between the upper flange portion 28 and the bottom of the second member 26. Specifically, the upper support portion 22 is formed in a groove shape by the upper flange portion 28 of the first member 25, the upper wall portion of the groove-shaped portion 27, and the upper edge of the bottom of the second member 26. The upper stud material 10a is fixed to the connecting member 20 by fitting the lower end of the upper stud material 10a into the groove-shaped portion of the upper support portion 22.

[0023] The lower support portion 23 is a portion that supports a plurality of lower studs 10 (lower studs 10b), and is formed in a groove shape that opens downward between the lower flange portion 28 and the bottom of the second member 26. Specifically, the groove shape of the lower support portion 23 is formed by the lower flange portion 28 of the first member 25, the lower wall portion of the groove-shaped portion 27, and the lower edge portion of the bottom of the second member 26. The lower stud material 10b is fixed to the connecting member 20 by fitting the upper end of the lower stud material 10b into the groove-shaped portion of the lower support portion 23.

[0024] The projection / retraction adjustment means 24 adjusts the projection / retraction dimension of the main body 21 relative to the base 2. The projection / retraction adjustment means 24 includes a screw member 31 and a rotating member 32. The screw member 31 includes a pin screw 33 extending from the main body 21 to the base 2, and a support plate 34 that supports the pin screw 33. The pin screw 33 is erected perpendicular to the support plate 34 and is perpendicular to the surface of the base 2. The tip of the pin screw 33 passes through the screw insertion holes 30, 29 and extends into the groove-shaped portion 27 of the first member 25. A nut 35 is threaded onto the portion of the tip of the pin screw 33 that protrudes from the bottom of the groove-shaped portion 27.

[0025] The support plate 34 is made of a metal plate and is square in plan view. The support plate 34 supports the pin screw 33 and is fixed to the base part 2 via adhesive 39. The adhesive 39 is applied over the entire back surface of the support plate 34 (the surface facing the base part 2). A boss part 36, a reinforcing rib 37, and a through hole 38 are formed on the support plate 34. The boss part 36 is a part for fixing the pin screw 33, and is formed in the center of the support plate 34. A female thread is formed on the inner peripheral surface of the boss part 36, and the base end of the pin screw 33 is screwed into and fixed.

[0026] The reinforcing ribs 37 are formed by pressing the plate material toward the base portion 2. The reinforcing ribs 37 extend radially from the boss portion 36 toward the outer periphery of the support plate 34. There are four reinforcing ribs 37 provided, and they are formed in a cross shape. The through holes 38 are holes through which adhesive 39 that fixes the support plate 34 to the base portion 2 enters, thereby improving adhesion. A large number of through holes 38 are formed in the flat portion excluding the reinforcing ribs 37.

[0027] The rotating member 32 is a part that abuts against the main body 21 and screws onto the bar screw 33 of the screw member 31. The rotating member 32 is disposed closer to the base 2 than the main body 21, and abuts against the end of the second member 26 on the base 2 side. The rotating member 32 is disk-shaped, and a boss 41 that screws onto the bar screw 33 is formed in the center thereof. An internal thread that screws onto the bar screw 33 is formed on the inner circumferential surface of the boss 41. The upper end of the peripheral edge of the rotating member 32 protrudes upward beyond the upper end of the main body 21, and the lower end of the peripheral edge of the rotating member 32 protrudes downward beyond the lower end of the main body 21. The part of the peripheral edge of the rotating member 32 that protrudes beyond the main body 21 serves as a grip that an operator holds when rotating the rotating member 32. As the rotating member 32 rotates, it moves in the axial direction of the rod screw 33 of the screw member 31, advancing and retracting relative to the base part 2, pushing and moving the main body part 21 toward the interior of the room. When moving the main body part 21 toward the base part 2, the rotating member 32 is moved toward the base part 2 relative to the rod screw 33, and the nut 35 that threads onto the tip of the rod screw 33 within the groove-shaped portion 27 of the first member 25 of the main body part 21 is rotated, pushing the main body part 21 toward the base part 2. The main body part 21 is clamped between the rotating member 32 and the nut 35, and its inward and outward position relative to the base part 2 is regulated.

[0028] Next, we will explain the method for constructing the wall structure 1. The method for constructing the wall structure 1 includes an access adjustment means installation step, a main body installation step, an access adjustment step, and a stud material installation step.

[0029] The entry / exit adjustment means installation process is a process of installing the entry / exit adjustment means 24 on the base portion 2. In the entry / exit adjustment means installation process, first, the support plate 34 is adhered to a predetermined position on the surface of the base portion 2. The adhesive 39 is applied over the entire back surface of the support plate 34 and penetrates into the through-hole 38. Next, the pin screw 33 is threadedly engaged with the boss portion 36 of the support plate 34, and the pin screw 33 is erected on the support plate 34. Thereafter, the rotating member 32 is threadedly engaged with the pin screw 33 to rotatably attach it. Note that in this embodiment, the pin screw 33 and the rotating member 32 are attached after the support plate 34 is adhered to the base portion 2, but the support plate 34 may be adhered to the base portion 2 with the pin screw 33 threadedly engaged with the rotating member 32 already attached to the support plate 34.

[0030] The main body installation process is a process of attaching the main body 21 to the entry / exit adjustment means 24. In the main body installation process, the second member 26 and the first member 25 of the main body 21 are inserted into the rod screw 33 of the entry / exit adjustment means 24, and a nut 35 is screwed onto the tip of the rod screw 33 to temporarily fix the main body 21 to the rod screw 33. The distance between the nut 35 and the rotating member 32 is set to be larger than the distance when the main body 21 is clamped, leaving space for the rotating member 32 to move forward and backward relative to the base part 2.

[0031] The ingress / egress adjustment process is a process of adjusting the ingress / egress dimension of the main body part 21 relative to the base part 2. In the ingress / egress adjustment process, the rotating member 32 is rotated from the inside of the room and moved in the axial direction of the rod screw 33. This allows the rotating member 32 to push and move the main body part 21 toward the inside of the room. When moving the main body part 21 toward the base part 2, the nut 35 provided at the tip of the rod screw 33 is turned to push the main body part 21 in. Once the ingress / egress adjustment is complete, the main body part 21 is clamped and fixed between the rotating member 32 and the nut 35.

[0032] The stud material installation process is a process of installing the stud material 10, which is divided into upper and lower parts. In the stud material installation process, first the upper and lower runner materials 11 are installed, and then the upper stud material 10a and the lower stud material 10b are installed respectively. The upper end of the upper stud material 10a is inserted into the upper runner material 11 from below, and the lower end is inserted into the upper support part 22 from above. The upper end of the lower stud material 10b is inserted into the lower support part 23 from below, and the lower end is inserted into the lower runner material 11 from above. After that, wall materials are attached to the stud materials 10, and the wall structure 1 is completed.

[0033] According to the wall structure 1 described above, the position of the stud material 10 relative to the base material 2 can be appropriately determined by adjusting the inward / outward dimension of the main body 21 of the connecting member 20. Therefore, compared to the conventional technology in which position adjustment was performed for each stud material, the construction labor and time required for position adjustment can be significantly reduced.

[0034] Furthermore, in the ingress / egress adjustment means 24, by rotating the rotating member 32, the rotating member 32 moves in the axial direction of the rod screw 33, thereby moving the main body 21. Therefore, the ingress / egress dimension of the main body 21 of the connecting member 20 can be easily adjusted. Furthermore, since the rotating member 32 protrudes from the main body 21, it can be easily rotated by gripping it from the inside of the room.

[0035] The main body 21 is constructed by combining a first member 25 with a hat-shaped cross section and a second member 26 with a groove-shaped cross section, which allows for increased strength. Furthermore, the groove-shaped upper support portion 22 and lower support portion 23 can be easily formed. The stud 10 can be easily fixed by fitting its end into the upper support portion 22 or lower support portion 23, while ensuring the required fixing strength. Furthermore, by changing the size of the first member 25, the width dimensions of the upper support portion 22 and lower support portion 23 can be easily changed, making it possible to accommodate studs of various sizes.

[0036] First member 25, second member 26, and rotating member 32 are integrated by screw member 31, which facilitates assembly and reduces the number of parts. In addition, the tip of screw 33 of screw member 31 is positioned within groove-shaped portion 27 of first member 25, so screw member 31 does not interfere with the wall material attached to wall base 3.

[0037] The screw insertion hole 29 of the first member 25 and the screw insertion hole 30 of the second member 26 are both made of elongated holes, so that errors can be absorbed when construction errors in the base portion 2 cause unevenness on the surface, causing the rod screw 33 to tilt.

[0038] Furthermore, since the stud material 10 is divided into upper and lower parts, the length dimension is small, it is less likely to bend, and it can be transported by elevator or the like.

[0039] While the above describes the embodiments of the present invention, the present invention is not limited to these embodiments, and appropriate design changes can be made to the materials, shapes, sizes, and other aspects of the design without departing from the spirit of the present invention. For example, in the above embodiment, the stud material 10 is divided into two pieces, and the connecting member 20 is provided in the middle in the height direction, but this is not limited to this. For example, in a high ceiling such as an open void, the stud material may be divided into three or more pieces, and multiple connecting members may be provided in multiple stages, so that the length can be transported by elevator.

[0040] The shape of the support plate 34 is not limited to that of the above embodiment and may be the shape shown in FIG. 9 . The support plate 44 of FIG. 9 is also made of a metal plate, like the support plate 34, has a square shape in a plan view, and supports a bolt (not shown). The support plate 44 has bolt holes 45 formed in its four corners and is fixed to the base via anchor bolts (not shown). A truncated cone-shaped protrusion 46 that bulges toward the stud is formed in the center of the support plate 44. A boss 47 is formed on the protrusion 46. The boss 47 is a portion for fixing the bolt and is formed in the center of the support plate 44, protruding from the surface of the protrusion 46 toward the base. A female thread 48 is formed on the inner peripheral surface of the boss 47, into which the base end of the bolt is threadedly engaged for fixation. A support plate 44 configured in this manner has a simpler configuration than the support plate 34, making it easier to manufacture the component.

[0041] In the wall structure 1 of the present invention, it is possible to increase the height dimension by lengthening the rod screws 33. This means that even if there is insulation in a building that requires high insulation, the rod screws 33 can penetrate the insulation material, allowing the same height wall to be constructed. When high insulation is required, by constructing the rod screws 33 from a material that can be expected to have an insulating effect, such as resin, it is possible to suppress a decrease in insulation performance and at the same time prevent thermal bridges.
