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 plurality of studs that engage with the upper and lower runner members, and vibration-proof members that are suspended across the plurality of studs that are spaced apart (see, for example, Patent Document 1). The wall panels are fastened to the studs with screws. To use such a wall base for a recessed wall, runner members and stud materials are laid along the concrete wall frame, and a stopper member is provided as needed (see Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-100301 [Patent Document 2] Japanese Patent Application Publication No. 11-270097 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional wall structures require many construction steps, such as foundation work to attach runner members, studs, and anti-vibration members, board work to attach board materials to the foundation, and finishing work to apply wallpaper to the board materials. In other words, building a wall requires a variety of work methods and craftsmen, resulting in a lot of construction work and construction costs. Furthermore, when renovating a wall, it is difficult to reuse materials with such wall structures.

[0005] From this perspective, an object of the present invention is to provide a wall structure that can be easily constructed, reduces construction labor and costs, and is highly recyclable. [Means for solving the problem]

[0006] In order to solve the above problem, the present invention provides a wall structure comprising a frame-shaped base frame attached to a frame-shaped base portion, and a wall board member attached to the frame-shaped base frame, wherein the wall board member is removably fixed to the frame-shaped base frame.

[0007] The "base portion" in this invention refers to a planar portion that serves as a base for attaching a frame-shaped base frame, and is composed of a structural body wall or a partition wall. According to the wall structure of this invention, a wall base can be easily formed by attaching the frame-shaped base frame to the base portion. In addition, since the frame-shaped base frame is integrated into a frame shape, it can be reused. Furthermore, since the wall board components are detachable, they can be separated and reused or discarded as they are.

[0008] In the wall structure of the present invention, it is preferable to further include connecting fittings that connect the frame-shaped base frame to the base portion, and the connecting fittings are capable of adjusting the distance between the frame-shaped base frame and the base portion. With this configuration, the frame-shaped base frame can be easily attached to the base portion and can absorb unevenness in the base portion.

[0009] In the wall structure of the present invention, the connecting fitting preferably includes a frame fixing plate portion fixed to the frame-shaped base frame, a base fixing plate portion fixed to the base portion, and a connecting plate portion connecting the frame fixing plate portion and the base fixing plate portion. With this configuration, the distance between the frame-shaped base frame and the base portion can be adjusted by deforming the connecting plate portion.

[0010] Furthermore, in the wall structure of the present invention, it is preferable that the connecting fittings are configured so that the distance between the frame-shaped base frame and the base portion can be adjusted by bending the connecting plate portion. With this configuration, the distance between the frame-shaped base frame and the base portion can be easily adjusted.

[0011] In the wall structure of the present invention, the wall board members are preferably made of corrugated cardboard plates, and the wall board members are preferably formed with insertion holes through which fastening members for fastening the wall board members to the frame-shaped base frame are inserted. This configuration allows the wall board members to be easily attached and detached. Furthermore, since the wall board members are made of corrugated cardboard, insertion holes can be easily formed, and the wall board members can be reused as recycled paper. Furthermore, since fastening members are inserted into the insertion holes of the wall board members, the wall board members themselves can be reused.

[0012] Furthermore, in the wall structure of the present invention, it is preferable that the upper end of the wall board member protrudes above the upper end of the frame-shaped base frame. With this configuration, for example, when constructing the wall structure 1 under a reinforced concrete ceiling, a clearance can be provided between the ceiling surface and the frame-shaped base frame, making installation easier. Furthermore, if the wall board member is made of cardboard, even if the ceiling surface is uneven, the upper end of the wall board member can be cut appropriately to abut against the ceiling surface, thereby absorbing the unevenness and facilitating installation. [Effects of the Invention]

[0013] The wall structure according to the present invention can reduce construction work and costs, making it easier to construct, and also improves recyclability. [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 is constructed using a reinforced concrete structural framework as the base. The wall structure according to this embodiment is constructed as a partition wall installed indoors, with wall materials laid on both sides of the base. As shown in Figures 1 to 3, the wall structure 1 includes a frame-shaped base frame 10, wall board members 30, and connecting fittings 50.

[0016] The frame-shaped base frame 10 is a part that is attached to the base part 2. The base part 2 is formed in a flat shape and is composed of, for example, a structural body wall or a partition wall made of reinforced concrete. The frame-shaped base frame 10 is a part that serves as a base for fixing the wall board member 30, and is arranged along the surface of the base part 2 at a predetermined distance from the base part 2. As shown in Figures 4 and 5, the frame-shaped base frame 10 is formed by combining long members 11, for example, made of lightweight steel, into a rectangular frame shape. The long members 11 are formed of two types: horizontal members 12 and vertical members 13.

[0017] The cross members 12 are arranged horizontally at the upper and lower ends of the frame-shaped base frame 10, and extend across the entire width of the frame-shaped base frame 10. The cross members 12 are made of channel steel with a U-shaped cross section. The upper cross member 12 is arranged so that the groove opening faces downward, and the lower cross member 12 is arranged so that the groove opening faces upward. Of the vertical plate portions of the cross members 12 (a pair of plate portions that form the sides of the groove), the vertical plate portion of the cross member 12 on the front side (inside the room) is shorter in height than the vertical plate portion on the back side (side of the base member 2).

[0018] The vertical members 13 are suspended between the upper and lower horizontal members 12, 12. One vertical member 13 is provided at each longitudinal end of the horizontal member 12, and two are provided in the longitudinal middle of the horizontal member 12. In other words, two rectangular frame portions 14, 14 are formed in the frame-shaped base frame 10. Depending on the shape and size of the frame-shaped base frame 10, there may be one rectangular frame portion or three or more. The two vertical members 13, 13 in the longitudinal middle of the horizontal member 12 are arranged adjacent to each other. The upper end of the vertical member 13 is inserted into the groove of the upper horizontal member 12, and the side of the horizontal member 12 and the side of the vertical member 13 are fastened with screws. An insertion hole 15 is formed on the surface side of the vertical member 13. A fixing member for attaching the wall board member 30 to the frame-shaped base frame 10 is inserted into the insertion hole 15.

[0019] As shown in FIG. 2, the frame-shaped base frame 10 includes a frame-shaped base frame 10 of standard dimensions and a frame-shaped base frame 10a that is placed at the upper end of the wall surface. The frame-shaped base frame 10 of standard dimensions has, for example, a width of approximately 900 mm and a height of approximately 887.5 mm. The frame-shaped base frames 10 are stacked two levels above the floor. In this embodiment, an opening 4 is formed on the side of the two-level stacked frame-shaped base frames 10. The two levels of frame-shaped base frames 10, 10 form the side edges of the opening 4.

[0020] The width of the upper frame-shaped base frame 10a is the same as the standard dimension, and the height is appropriately set according to the ceiling height of the room. In other words, the height of the upper frame-shaped base frame 10a is the ceiling height minus the height of two standard frame-shaped base frames 10. The upper frame-shaped base frame 10a is also positioned above the opening 4, forming the upper edge of the opening 4.

[0021] When a beam shape occurs, a frame-shaped base frame 10b is provided to face the beam shape portion 5 (see FIG. 1). The frame-shaped base frame 10b of the beam shape portion 5 is disposed on the side of the beam shape, and has a width dimension that is, for example, the reference dimension minus the width dimension of the beam shape, and a height dimension that is the same as the height dimension of the frame-shaped base frame 10a at the upper end.

[0022] The wall board component 30 is a plate-like component attached to the front side (inside the room) of the frame-shaped base frame 10, and is removably fixed to the frame-shaped base frame 10 via a fixing member. The fixing member is, for example, made of a resin anchor. The resin anchor is an expansion anchor made of vinyl chloride, and when pressed from the wall board component 30 side toward the frame-shaped base frame 10 side, the tip of the leg is pushed out and expanded, and is engaged with the frame-shaped base frame 10. Note that the expansion anchor of this embodiment can be easily removed by rotating the shaft with a screwdriver or the like from the fixed state.

[0023] The wall board members 30 are made of corrugated cardboard plates. The wall board members 30 have a rectangular shape when viewed from the front. The wall board members 30 are fixed to the frame-shaped base frame 10 in groups of two, one for each rectangular frame portion 14. Insertion holes 31 (see FIG. 1 ) through which fixing members are inserted are formed in the four corners of the wall board members 30. The insertion holes 31 are formed at positions corresponding to the insertion holes 15 formed in the vertical members 13 of the frame-shaped base frame 10.

[0024] The wall unit 3 is formed by the frame-shaped base frame 10 and the wall board members 30. In this embodiment, as shown in FIG. 1 , the wall board members 30 include a standard-sized wall board member 30 attached to the frame-shaped base frame 10, an upper wall board member 30a attached to the frame-shaped base frame 10a located at the top of the wall surface, and a formwork wall board member 30b attached to the frame-shaped base frame 10b located at the beam-shaped portion. The standard-sized wall board member 30 has a width of approximately 440 mm and a height of approximately 877.5 mm. Thus, two wall board members 30 are attached horizontally to the frame-shaped base frame 10, with a joint width of approximately 10 mm between the wall board members 30. The shape and size of the wall board members 30 are appropriately determined depending on the ceiling height and the size of the opening 4. Wall board members 30a and 30b with small upper end heights may not be provided.

[0025] The width of the upper wall board member 30a is the same as the standard dimension, and the height is appropriately set according to the ceiling height of the room. In other words, the height of the upper wall board member 30a is the ceiling height minus the height and joint width of two standard wall board members 30. The upper frame-shaped base frame 10a and the wall board member 30a form the upper wall unit 3a.

[0026] The width of the wall board member 30b of the beam section 5 is, for example, the standard width minus the beam width and joint width, and the height is the same as the height of the wall board member 30a at the upper end. The frame-shaped base frame 10b of the beam section 5 and the wall board member 30b form the wall unit 3b of the beam section 5.

[0027] Wall board members 30c are provided to cover the edges of the wall located around the periphery of the opening 4 (see FIG. 3). The wall board members 30c are elongated plates with a width equal to the thickness of the wall, and are arranged perpendicular to the other wall board members 30. The wall board members 30c are abutted against the side surfaces of the vertical members 13 and fastened with screws. Note that the method of fastening the wall board members 30c is not limited to fastening with screws. For example, they may be fastened using vinyl chloride expansion anchors. Wall board members 30c are also provided on the side surfaces of the frame-shaped base frame 10 located at the side edges of the opening 4 and on the underside of the frame-shaped base frame 10a located at the upper edge of the opening 4 (see FIG. 1).

[0028] The connecting fitting 50 is a member that connects the frame-shaped base frame 10 to the base part 2. The connecting fitting 50 is configured to be able to adjust the distance between the frame-shaped base frame 10 and the base part 2. As shown in Figures 6 and 7 , the connecting fitting 50 includes a frame fixing plate part 51, a base fixing plate part 52, and a connection plate part 53.

[0029] The frame fixing plate portion 51 is a portion fixed to the frame-shaped base frame 10 and has a rectangular shape. A screw insertion hole 54 is formed in the frame fixing plate portion 51. The screw insertion hole 54 is formed in one location in the middle of the frame fixing plate portion 51 in the width direction, above the middle of the frame fixing plate portion 51 in the height direction. The frame fixing plate portion 51 abuts against the back surface of the horizontal member 12 or the vertical member 13 of the frame-shaped base frame 10 and is fixed with a screw V (see FIG. 8). The positions and number of the screw insertion holes 54 are not limited to those in this embodiment and are determined appropriately depending on the shape and weight of the wall unit 3.

[0030] The base fixing plate portion 52 is a rectangular portion that is fixed to the surface of the base portion 2. The base fixing plate portion 52 has a larger area than the frame fixing plate portion 51 and protrudes downward more than the frame fixing plate portion 51. An anchor insertion hole 55 is formed in the base fixing plate portion 52. The anchor insertion hole 55 is formed in one location in the widthwise middle of the base fixing plate portion 52, in the portion that protrudes downward. An anchor bolt B attached to the base portion 2 is inserted into the anchor insertion hole 55. The base fixing plate portion 52 abuts against the surface of the base portion 2 and is fixed via the anchor bolt B (see FIG. 8 ). The position and number of the anchor insertion holes 55 are not limited to those in this embodiment and can be determined appropriately depending on the shape and weight of the wall unit 3. Before installation, the base fixing plate portion 52 is arranged parallel to the frame fixing plate portion 51. If the surface of the base portion 2 is inclined due to an error in construction, the frame fixing plate portion 51 and the base fixing plate portion 52 may not be parallel to each other after installation.

[0031] The connecting plate 53 is a member that connects the frame fixing plate 51 and the base fixing plate 52. The connecting plate 53 has two thin plate portions 56, 56. The thin plate portions 56 are continuous with both widthwise ends of the frame fixing plate 51 and extend perpendicular to the frame fixing plate 51 toward the base fixing plate 52. The thin plate portions 56, 56 are arranged parallel to each other. The base fixing plate 52 is continuous with the tip of the thin plate portions 56, 56 and is perpendicular to the thin plate portion 56. The base fixing plate 52 is bent toward the opposite side from the frame fixing plate 51 with respect to the connecting plate 53, and has a crank shape (Z-shape) in plan view. The thin plate portions 56, 56 are strong enough to grip the wall unit 3 and are deformed by hitting the frame-shaped base frame 10 with a rubber hammer or the like when installing the frame-shaped base frame 10. In other words, the connecting fitting 50 is configured so that the distance between the frame-shaped base frame 10 and the base portion 2 can be adjusted by bending the connecting plate portion 53.

[0032] When constructing the wall structure 1 having the above-described configuration, first, the connecting fittings 50 are attached to the back side of the frame-shaped base frame 10, and then the base portion 2 is attached to the frame-shaped base frame 10. Then, the frame-shaped base frame 10 is struck with a rubber hammer or the like to deform the connecting plate portion 53 (see Figure 8), thereby adjusting the movement of the frame-shaped base frame 10 in and out. This makes the surface of the frame-shaped base frame 10 flat and flush, and makes it possible to absorb any unevenness in the surface of the base portion 2.

[0033] Thereafter, the wall board member 30 is laid on the surface side of the frame-shaped base frame 10, and the fixing member, a vinyl chloride expansion anchor, is pushed through the insertion hole 31 and into the insertion hole 15. This causes the tip of the fixing member to expand and engage with the frame-shaped base frame 10, fixing the wall board member 30 in place.

[0034] According to the wall structure 1 of this embodiment, the wall base can be easily formed by attaching the frame-shaped base frame 10 to the base portion 2, which significantly reduces the construction effort and time compared to the conventional method of assembling runner members and stud materials at the construction site. In particular, in this embodiment, the connecting plate portion 53 of the connecting fitting 50 is deformable, so that the frame-shaped base frame 10 can be easily adjusted for ingress and egress (adjusting the distance between the frame-shaped base frame 10 and the base portion 2) by tapping it, and unevenness in the base portion 2 can be absorbed.

[0035] Furthermore, since the wall board member 30 is made of a cardboard plate material, the insertion holes 31 can be easily formed. Also, since it is made of cardboard, it can be reused as recycled paper. Furthermore, since the wall board member 30 only requires that fixing members be inserted into the insertion holes 31 and the fixing members can be easily removed, the wall board member 30 itself can be reused or discarded as is.

[0036] Furthermore, in this embodiment, the wall structure 1 can be easily constructed with a simple and few steps by attaching the frame-shaped base frame 10 and fixing the wall board members 30. In addition, the light steel construction work that was previously performed can be omitted, reducing the construction work.

[0037] Next, the configuration of a wall structure 1a according to a modified example will be described with reference to FIG. 9. In this modified example, the wall structure 1a is formed below a ceiling 6 formed by exposing a reinforced concrete skeleton. As in the above embodiment, the wall structure 1a includes a frame-shaped base frame 10, wall board members 30, and connecting metal fittings 50. The frame-shaped base frame 10 is disposed with a clearance from the surface of the ceiling 6 and is fixed to the base part 2 via the connecting metal fittings 50. The wall board members 30 are attached to the surface side of the frame-shaped base frame 10 via expansion anchors made of polyvinyl chloride. The upper end of the wall board members 30 protrudes above the upper end of the frame-shaped base frame 10. Specifically, the upper end of the wall board members 30 protrudes above the upper end of the frame-shaped base frame 10 by the amount of clearance between the frame-shaped base frame 10 and the ceiling 6 so that the upper end of the wall board members 30 abuts against the surface (underside) of the ceiling 6. In addition, if there are unevenness on the surface of the ceiling 6, a wall board member 30 with a long protruding length is used and its upper end is cut off so that the upper end of the wall board member 30 abuts against the surface of the ceiling 6.

[0038] According to the wall structure 1a configured as described above, the frame-shaped base frame 10, which is difficult to change its shape, can be easily installed by providing a clearance between it and the ceiling 6, regardless of whether the surface of the ceiling 6 is uneven. On the other hand, the wall board member 30 is to be abutted against the surface of the ceiling 6, but because it is made of a corrugated board material, its upper end can be cut to fit the surface of the ceiling 6. Therefore, the wall board member 30 can also be easily installed regardless of whether the surface of the ceiling 6 is uneven.

[0039] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and appropriate design changes can be made to the materials, shapes, sizes, and the like without departing from the spirit of the present invention. For example, in the above-described embodiments, the frame-shaped base frame 10 is composed of long light-gauge steel members 11, but this is not limiting. The long members may be made of materials other than metal, such as wood or resin.

[0040] In addition, in the above embodiment, the wall structure 1 is applied to a partition wall in which wall paneling is laid on both sides of the wall base, but it can also be applied to a wall of other structure in which wall paneling is laid on one side of the wall base, for example.

[0041] In the above embodiment, the connecting fitting 50 has a crank shape in plan view, with the frame fixing plate portion 51, the base fixing plate portion 52, and the connecting plate portion 53 intersecting each other at right angles. However, this is not limited to this. As shown in FIG. 10 , the connecting fitting 60 may have an L-shape in plan view. The connecting fitting 60 includes a frame fixing plate portion 61, a base fixing plate portion 62, and a connecting plate portion 63. The base fixing plate portion 62 and the connecting plate portion 63 intersect at right angles, and the frame fixing plate portion 61 and the connecting plate portion 63 are formed on the same plane. The base fixing portion 62 abuts against the base portion 2 and is fixed with anchor bolts B. The frame fixing plate portion 61 abuts against the side of the vertical member 13 of the long member 11 of the frame-shaped base frame 10 and is fixed with screws V. The connecting plate portion 63 and the frame fixing plate portion 61 have slits (not shown) extending in the protruding direction, which makes the connecting plate portion 63 more easily deformable. As a result, when installing the frame-shaped base frame 10, the connecting fittings 60 can be deformed by hitting the frame-shaped base frame 10 with a rubber hammer or the like (see FIG. 10(b)). Therefore, in the connecting fittings 60 as well, the distance between the frame-shaped base frame 10 and the base part 2 can be adjusted by bending the connecting plate part 63.
