Description

Technical Field

[0001] The present invention relates to the technical field of a support structure for a panel body attached to a wall surface.

Background Art

[0002] Today, there are demands such as improving the design by attaching a panel body (decorative panel board) to a wall surface. In such a case, a vertical joint member having locking protrusions is laminated on the surface of a base material attached to the wall surface, and the panel body is attached to the wall surface by locking a locking hole formed in the panel body to the locking protrusions formed in the vertical joint member (see, for example, Patent Document 1). The panel body attached to the wall surface in this way is unstable simply by being locked to the locking protrusions. Therefore, in the conventional method, an L-shaped support fitting is fixed to the lower edge of the vertical joint member with screws, and the lower edge of the panel body is supported by the support fitting. In addition, when the panel body widely covers the wall surface between the ceiling surface and the floor surface, a support portion for supporting the lower edge of the panel body is formed by bending on a floor side member (floor rail member) provided on the wall surface in a state of standing upright from the floor surface (see, for example, Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when the support fitting is fixed to the vertical joint material with screws, not only does the number of parts increase because the support fitting is required as a separate member, but there is also a problem that the workability is poor because the work of attaching the support fitting is required. On the other hand, in the case where the support portion is bent and formed on the floor side member, there is a fear that the locking position of the panel body by the locking projection provided on the vertical joint material and the support position of the panel body by the support piece portion provided on the floor side member are displaced left and right, and the support of the panel body becomes unstable. To avoid this, it is necessary to consider positioning the support position of the panel body and the support piece portion formed on the floor side member, and there are problems to be solved by the present invention in these.

Means for Solving the Problems

[0005] The present invention was created for the purpose of solving these problems in view of the above circumstances. The invention of claim 1 is that a vertically long flat plate-shaped vertical joint material is screwed to a wall surface, and locking holes formed at the left and right edge portions facing the wall surface of the panel body are locked to a plurality of locking projections arranged in a vertical row with a gap in the vertical joint material, so that when configuring to be attachable to the wall surface of the panel body, a support piece portion for supporting the lower edge of the panel body locked to the locking projection is formed at the lower end portion of the vertical joint material, which is a support structure of the panel body. The invention of claim 2 is the support structure of the panel body according to claim 1, characterized in that the support piece portion is formed by bending the lower end of the vertical joint material. The invention of claim 3 is that when adjacent left and right panel bodies are attached in a planar arrangement state, on the vertical joint material, a plurality of locking projections and screw fixing positions provided respectively for locking the adjacent edge portions of the left and right panel bodies are provided in a state of being located on the same vertical line, and below the extension of the vertical line of the left and right locking projections and the screw fixing positions, a support piece portion for supporting the lower edges of the left and right panel bodies is provided, which is the support structure of the panel body according to claim 1. In the invention according to claim 4, when the adjacent first and second panel bodies are attached to a corner portion that bends in a cornered state, the vertical joint member is such that first and second vertical joint members corresponding to the first and second panel bodies are respectively screwed to the wall surface, and the screw fixing row provided on the vertical row line of the first and second vertical joint members has at least two vertical row lines, namely, a first vertical row line closest to the corner portion side and a second vertical row line spaced apart from the corner portion. The extension length of the extended edge portion extending from the first vertical row line of the first and second vertical joint members toward the corner portion side is such that the first vertical joint member is longer than the second vertical joint member. The corner side edge portion of the second panel body attached to the second vertical joint member is positioned more on the corner side than the surface of the first panel body attached to the first vertical joint member. Further, the support piece portions formed on the first and second vertical joint members are set to a length from the edge on the second vertical row line side of the vertical joint member to the vertical row line of the first vertical row line. This is the support structure of the panel body according to claim 1, characterized in that

Effect of the Invention

[0006] By adopting the invention according to claim 1, by locking the locking hole formed in the panel body to the locking projection formed in the vertical joint member provided on the wall surface, the panel body can be attached to the wall surface. As a result, a support piece portion for supporting the lower edge of the panel body is formed at the lower end portion of the vertical joint member, so that there is no need to prepare a special support piece portion as a separate member, and the number of parts can be reduced and the workability can be improved. By adopting the invention according to claim 2, the support piece portion is formed by bending the lower end of the vertical joint member, and thus can be easily formed. According to the invention of claim 3, in the case where adjacent left and right panel bodies are attached to a single vertical joint member in a flat arrangement state, the vertical joint member is provided with a plurality of locking protrusions and screw fixing positions that are respectively provided for locking the adjacent edge portions of the left and right panel bodies on the same vertical line, and moreover, a support piece portion is provided below the extension of the vertical line of the left and right locking protrusions and the screw fixing positions to support the lower edge of the left and right panel bodies. As a result, the panel body to be attached to the wall surface via the vertical joint member has the screw fixing position of the vertical joint member to the wall surface, the locking position by the locking protrusion of the panel body, and the support position by the support piece portion of the lower edge of the panel body in a vertical row, enabling stable attachment support of the panel body to the wall surface. According to the invention of claim 4, in the case where adjacent first and second panel bodies are attached to a corner portion that bends into a corner state, as the vertical joint member, first and second vertical joint members corresponding to the first and second panel bodies are respectively screwed to the wall surface, and at least two vertical lines are formed by the screw fixing row provided in a vertical row of the first and second vertical joint members, namely, the first vertical line closest to the corner portion side and the second vertical line spaced apart from the corner portion. And the extension length of the extended edge portion extending from the first vertical line of the first and second vertical joint members toward the corner portion side is such that the first vertical joint member is longer than the second vertical joint member. The corner side edge portion of the second panel body attached to the second vertical joint member is located closer to the corner portion than the surface of the first panel body attached to the first vertical joint member. Moreover, the support piece portions formed on the first and second vertical joint members are set to be long with a length from the edge on the second vertical line side of the vertical joint member to the vertical line of the first vertical line. As a result, the lower edges of the first and second panel bodies attached to the corner portion in a corner state can be reliably supported. Moreover, the corner side edge portion of the first vertical joint member provided for attaching the first panel body is in a state closer to the corner portion than the surface of the second panel body, so that the corner side edge or the wall surface of the first joint member cannot be visually recognized from the gap between the edge portions of the first and second panel bodies, and the extended edge portion of the first vertical joint member can be visually recognized, thus avoiding the loss of appearance.

MODE FOR CARRYING OUT THE INVENTION

[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a panel body, and the panel body 1 is attached and fixed to a wall surface W of a building via vertical joint members 2 provided with a gap on the left and right. In the present embodiment, the vertical joint members 2 are not directly attached and fixed to the wall surface W, but a base material 3 directly attached and fixed to the wall surface W via screws 3a is interposed between the wall surface W and the vertical joint members 2, and the vertical joint members 2 are attached and fixed to the wall surface W via screws (bolts, fasteners) 2a. And the panel body 1 is configured to be attached to the wall surface W by fitting and locking locking holes 1a provided on the back surfaces (surfaces facing the wall surface W) of the left and right edge portions of the panel body 1 into a pair of left and right locking projections 2d provided on the vertical joint members 2 as described later. All of these are the same as in the prior art. Incidentally, as the vertical joint members 2, the present invention can be implemented even if they are provided directly on the wall surface W without the base material 3.

[0009] Horizontal long flat ceiling side members and floor side members (ceiling rail members, floor rail members) 4 and 5 are attached to the upper and lower edge portions of the wall surface W via screws 4a and 5a. On the other hand, the base material 3 is formed in a vertically long flat plate shape having the same thickness (for example, 1 mm) as the ceiling side member 4 and the floor side member 5, and is not laminated with the ceiling side member 4 and the floor side member 5 between the lower end edge 4b of the ceiling side member 4 and the upper end edge 5b of the floor side member 5, and is attached to the wall surface W via screws 3a. On the other hand, the vertical joint members 2 are set to have a narrower left - right width than the base material 3 and are in a vertically long flat plate shape. By being applied to the surface (front surface, front) of the screw - fixed base material 3, the base material 3 is interposed between the wall surface W and the vertical joint members 2, and the vertical joint members 2 are attached and fixed to the wall surface W via screws 2a. The upper and lower end edges 2b and 2c of the vertical joint members 2 are set to be attached and fixed to the wall surface W via screws 2a in a state of being polymerized (laminated) from the surface side with respect to the ceiling side member 4 and the floor side member 5. And the vertical joint members 2 are attached in such a state that the base material 3 is interposed therebetween, so that the upper and lower end edges 2b and 2c are attached and fixed in a state of being laminated on the ceiling side member 4 and the floor side member 5, and are attached and fixed to the wall surface W in a state of being raised by the thickness of the ceiling side member 4 and the floor side member 5. In this case, the positions of the screws 2a for fixing the vertical joint material 2 are arranged such that a pair of them are located on the vertical column lines X1 and X2 in a vertical column shape side by side on the left and right.

[0010] Furthermore, a plurality of locking protrusions 2d are formed on the vertical joint material 2 with a gap in the vertical direction, with a pair of them being formed side by side on the left and right with the left and right edges notched and having a gap in the vertical direction. The left and right locking protrusions 2d are formed in a state where they are located or substantially located on the vertical column lines X1 and X2 of the screw 2a. The panel body 1 has locking holes 1a formed at both left and right ends of the back surface (rear surface, back) facing the wall surface W of the panel body 1. By locking the locking holes 1a to the locking protrusions 2d, the panel body 1 can be attached to the wall surface W.

[0011] And by doing so, although with the base material 3 in between, the panel body 1 is attached and fixed to the left and right vertical joint materials 2 attached and fixed to the wall surface W. The lower edge portion 1b of the panel body 1 attached in this way is configured to be supported by the support piece portion 2e provided at the lower edge portion 2c of the vertical joint material 2. Specifically, the support piece portion 2e is formed by bending at a right angle forward a tongue-shaped extension (protrusion) from the lower end of the lower edge portion 2c laminated on the floor side material 5 of the vertical joint material 2. The support piece portion 2e supports the panel body 1 by abutting against each lower edge portion 1b of the left and right panel bodies 1 attached to one vertical joint material 2 from below. The support piece portion 2e is formed as a pair on the left and right corresponding to the left and right panel bodies 1.

[0012] And in this case, since the support piece portion 2e is attached and fixed in a state where the lower edge portion 2c of the vertical joint material 2 is laminated on the floor side material 5, it is arranged at a position lower than the upper edge 5b of the floor side material 5. As a result, the lower edge portion 1b of the panel body 1 is configured to be supported by the vertical joint material 2 in a state of covering the floor side material 5 up to the vertical intermediate portion covering the upper edge 5b of the floor side material 5. Moreover, the support piece portions 2e formed on the vertical joint material 2 to support the lower edge portion 1b of the panel body 1 are provided in a state where a pair of them are divided left and right while being located on the lower extension line of the vertical line X of the locking projection 2d at the fixing position of the screw 2a. Of course, it may be configured such that the pair of left and right ones are connected in series.

[0013] In the present embodiment configured as described above, by locking the locking hole 1a formed on the back surface of the panel body 1 facing the wall surface W to the locking projection 2d formed on the vertical joint material 2 provided on the wall surface W, the panel body 1 can be attached to the wall surface W. In this case, as a result of the support piece portion 2e for supporting the lower edge 1b of the panel body 1 being formed at the lower edge portion 2c of the vertical joint material 2, there is no need to specially prepare the support piece portion as a separate member, and the number of parts can be reduced. In addition, the on-site attachment workability of the support piece portion as a separate member becomes unnecessary, and the workability can be improved. Moreover, in this case, since the support piece portion 2e can be formed by bending the extension portion formed at the lower end of the vertical joint material 2, the support piece portion 2e can be easily formed.

[0014] Moreover, in this case, one vertical joint material 2 is attached in a state where the adjacent left and right panel bodies 1 are arranged in a planar manner. In this case, on the vertical joint material 2, a plurality of locking projections 2d provided in pairs on the left and right for locking the adjacent edge portions of the left and right panel bodies 1 and the left and right fixing positions of the screws 2a are provided in a state where they are located on the same line X in the vertical column. Moreover, below the extension of the vertical column line X where the left and right locking projections 2d and the fixing positions of the screws 2a are arranged, left and right support piece portions 2e for supporting the lower edge portions 1b of the left and right panel bodies 1 are provided. As a result, as the panel body 1 attached to the wall surface W via the vertical joint material 2, the fixing position of the vertical joint material 2 to the wall surface W by the screw 2a, the position where the locking projection 2d to which the locking hole 1a of the panel body 1 is locked is provided, and the support position by the support piece portion 2e of the lower edge portion 1b of the panel body 1 are arranged in a vertical column on the same vertical column line X, and the panel body 1 can be stably attached and supported to the wall surface W.

[0015] In this case, a support piece portion 2e for supporting the lower end edge portion 1b of the panel body 1 is formed at the lower end edge portion 2c of the vertical joint material 2 provided in a stacked state on the floor side member 5. As a result, the panel body 1 is supported at a lower position than the upper end edge 5b of the floor side member 5 at the lower end edge portion 1b, and the lower end edge portion 1b of the panel body 1 can be positioned below the upper end edge 5b of the floor side member 5. For this reason, the upper end edge 5b of the floor side member 5 can be covered by the panel body 1, and the visibility is not impaired.

[0016] Of course, the present invention is not limited to the case where a pair of left and right panel bodies 1 are attached in a planar shape as in the above-described embodiment. The present invention can be similarly implemented for a concave corner portion in the shape of an inward corner that is bent, and conversely, for a convex corner portion in the shape of an outward corner that is bent. In particular, in the case of an inward corner portion, it is preferable to be configured as in the second embodiment described below.

[0017] In the second embodiment, as the inward corner portion C, there are a first wall surface W1 and a second wall surface W2 that are bent at a right angle. The first vertical joint material 21 and the second vertical joint material 22 are attached and fixed to these first and second wall surfaces W1 and W2 via screws 21a and 22a. Then, by engaging locking holes 11a and 12a formed in the first and second panel bodies 11 and 12 with locking projections 21d and 22d provided on these first and second vertical joint materials 21 and 22, the first and second panel bodies 11 and 12 are attached to the first and second wall surfaces W1 and W2.

[0018] And in this case, since the first and second vertical joint members 21 and 22 are configured to attach the first and second panel bodies 11 and 12 to the edges of the first and second wall surfaces W1 and W2, unlike the case of attaching the two panel bodies 1 adjacent to each other in a planar manner as in the above-described embodiment, it is only necessary to attach one panel body 11 or 12. Therefore, as the locking protrusions 21d and 22d formed on each of the vertical joint members 21 and 22, they are provided on the vertical column line X1 biased toward the vertical edge 21g side closer to the corner portion C side, and are respectively attached to the first and second wall surfaces W1 and W2 via screws 21a and 22a to the first and second wall surfaces W1 and W2 configured in this way.

[0019] Specifically, the first and second vertical joint members 21 and 22 are respectively fixed by a pair of screws 21a and 22a arranged in parallel from left to right, similar to the case of the vertical joint member 2 of the first embodiment. As the vertical column lines at the fixing positions of the screws 21a and 22a, it is provided with the first vertical column line X1 closest to the corner portion C side and the second vertical column line X2 spaced apart from the corner portion C. These first and second vertical column lines X1 and X2 are set such that the distances (widths) from the vertical edges 21f and 22f on the side spaced apart from the corner portion C of the first and second vertical joint members 21 and 22 are the same as the distances of the pair of left and right vertical column lines X1 and X2 formed in the first embodiment. And the locking protrusions 21d and 22d formed on the first and second vertical joint members 21 and 22 are formed to be located on the first vertical column line X1 close to the corner portion C. And in this embodiment, the support piece portions 21e and 22e formed at the lower edges of the first and second vertical joint members 21 and 22 do not support the lower edge portions 1b of the panel bodies 1 adjacent to each other from left to right as in the above-described embodiment. Instead, since it is only necessary to support the lower edge portions 11b and 12b of the first and second panel bodies 11 and 12 individually, they are configured to be wide from left to right up to the first and second vertical column lines X1 and X2, and are configured to be able to support the panel bodies 11 and 12 more reliably as will be described later.

[0020] Then, first and second vertical joint members 21 and 22 are attached and fixed to the first and second wall surfaces W1 and W2 via screws 21a and 22a in this manner, and first and second panel bodies 11 and 12 are respectively attached to the first and second vertical joint members 21 and 22. In that case, the vertical edge 12c on the corner C side of the second panel body 12 is set to fit into the gap S1 between the vertical edge 11c on the corner C side of the first panel body 11 and the second wall surface W2. However, the fitting of the vertical edge 12c of the second panel body 12 into the gap S1 between the vertical edge 11c of the first panel body 11 and the second wall surface W2 is set to be a loose fitting with a gap S2 remaining between the vertical edge 11c of the first panel body 11 and the surface plate 12d of the second panel body 12 that has been fitted in.

[0021] Moreover, in this case, the vertical edge portions 21g and 22g on the corner C side of the first and second vertical joint members 21 and 22 are longer in the left - right direction than in the case of the vertical joint member 2 of the first embodiment and are extension edge portions extending to the corner C side. However, the first extension edge portion 21g formed on the first vertical joint member 21 is longer than the second extension edge portion 22g formed on the second vertical joint member 22. Only the first extension edge portion 21g is visible from the gap S2 between the vertical edge 11c of the first panel body 11 and the surface plate 12d of the second panel body 12, and consideration is given so that the edge of the first extension edge portion 21g cannot be seen, and consideration is given so that the visibility at the corner C is not impaired.

[0022] And in this case, first and second support piece portions 21e and 22e formed at the lower edge portions of the first and second vertical joint members 21 and 22 to support the lower edge portions 11b and 12b of the first and second panel bodies 11 and 12 attached to the corner C that is in a corner - folding state are set to be long (wide) from the position on the first vertical column line X1 side where the locking protrusions 21d and 22d of the respective vertical joint members 21 and 22 are located to the position on the second vertical column line X2 side spaced apart from the corner C. As a result, the support by the support piece portions 21e and 22e of the lower edge portions of the first and second panel bodies attached to the corner C in the corner - folding state is ensured.

[0023] Incidentally, the present invention can be applied to a structure in which a panel body is locked and attached to a vertical joint material attached to a wall surface. As in the above embodiment, when attaching panel bodies adjacent to each other left and right, it is of course not limited to the case of attaching a panel body to a corner portion in a corner shape, and in the case of the panel body 1 attached to the wall surface W at the end (the panel body 1 at the left end in FIG. 1), the vertical joint material 2 can be implemented using a vertical joint material similar to the second vertical joint material 22 employed in the second embodiment, for example.
