Description

[Technical Field]

[0001] The present invention relates to a base panel that is easy to attach and remove, and to a partition panel and a wall panel that use the same. [Background technology]

[0002] For example, wall panels using tiles as a finishing material are usually installed by adhering the finishing material to a base material such as gypsum board (see, for example, Non-Patent Document 1). The base material is fixed directly to the wall surface of the building or via a base member such as lightweight steel. [Prior art documents] [Non-patent literature]

[0003] [Non-Patent Document 1] https: / / www.dinaone.co.jp / special / wall-tile-construction-method / Summary of the Invention [Problem to be solved by the invention]

[0004] In the case of using such conventional technology, when dismantling a wall panel, the tiles must be destroyed and discarded, which poses a problem in that they cannot be reused.

[0005] In view of the problems of the prior art, the object of this invention is to provide a base panel that is easy to install and remove by introducing a base plate made of steel plate, and that allows for the easy reuse of finishing materials such as tiles, as well as a partition panel and a wall panel that use the same. [Means for solving the problem]

[0006] The gist of the invention of claim 1 for achieving this purpose is that it comprises a vertically long rectangular steel base plate and a backing material attached to the back side of the base plate, and the base plate has mounting pieces formed on the back side of each of the left and right side ends, which have vertical rows of upward slotted work holes for screws, and operation holes corresponding to the slots of each work hole are opened on the front side, so that the base plate can be fastened with screws inserted through each operation hole into the slot of each work hole.

[0007] In addition, reinforcing plates can be attached to the upper and lower ends of the back surface of the base plate, and each mounting piece can have a reinforcing rib formed at its tip that is bent 90 degrees toward the back surface.

[0008] In addition, the base plate may have reinforcing plates attached to the upper and lower ends on the back side, and each mounting piece may have a reinforcing rib at the tip that is bent at 90 degrees toward the back side.

[0009] The gist of the configuration of the invention of claim 5 is that a base panel of any of claims 1 to 4 is screwed to the left and right supports of the partition device, and a finishing material is adhered to the surface side of the base panel.

[0010] The gist of the invention of claim 6 is that a base panel of any of claims 1 to 4 is screwed to the wall of a building and a finishing material is adhered to the surface side of the base panel. [Effects of the Invention]

[0011] According to the configuration of the invention of claim 1, the base plate can be removably fastened with screws that pass through the left and right operation holes and into the slots of the corresponding work holes. However, for ease of subsequent removal, the screws are screwed in to an appropriate depth during installation. Therefore, when removing the base plate, the entire plate is pushed upward to move the screws in the slots relative to the work holes, and then the entire plate is moved parallel to the surface to remove the heads of the screws from the work holes, making installation and removal of the entire plate easy.

[0012] The screws are, for example, countersunk head screws, and the work hole and slot are sized to allow the head of the screw to pass through and not pass through, respectively, the operating hole is sized to allow the head of the screw to pass through but also to allow a screw driving tool to be inserted, and the slot is sized to allow the neck of the screw to be inserted.The backing material on the back side of the base board is a so-called "backing material" to ensure the rigidity of the base board, and may be, for example, an inorganic material such as gypsum board or a wood material such as plywood.

[0013] The reinforcing plate on the back side of the base plate can sufficiently increase the rigidity of the upper and lower parts of the base plate. In addition, the reinforcing ribs formed at the tip of each mounting piece can increase the rigidity of the mounting piece and improve the mounting strength of the base panel.

[0014] According to the configuration of the invention of claim 5, the base panel is fastened to the left and right support posts of the partition device with screws, making it easy to attach and remove, and it is possible to reuse finishing materials such as tiles that are adhered to the surface of the base panel. In addition to tiles, colored glass plates, natural stone plates such as marble, resin plates, etc. can be used as finishing materials.

[0015] When the configuration of the invention of claim 6 is used, it is the same as when the configuration of the invention of claim 5 is used, except that the object to which the base panel is screwed is the wall surface of a building or a base component such as lightweight steel on the wall.

[0017] Hereinafter, an embodiment of the invention will be described with reference to the drawings.

[0018] The base panel 10 comprises a base board 11 and a backing material 12 attached to the back side of the base board 11 (Fig. 1). Figs. 1(A) to 1(C) are respectively an overall back view and an enlarged cross-sectional view of a main part corresponding to the arrows X1-X1 and X2-X2 in Fig. 1(A), and Figs. 1(D) and 1(E) are schematic enlarged perspective views of a main part as seen from the front side and the back side, respectively.

[0019] The base plate 11 is made of a vertically long, rectangular steel plate. The left and right side edges of the base plate 11 are each folded back on the back surface to form mounting pieces 11a with a U-shaped cross section, and the tips of the mounting pieces 11a are bent 90° back to form reinforcing ribs 11b. The mounting pieces 11a are parallel to each other and spaced a distance d apart from the front surface of the base plate 11.

[0020] The left and right mounting pieces 11a, 11a each have a vertical row of work holes 11c, 11c... with upward slots 11d at a predetermined pitch. Furthermore, on the surface side of the base plate 11, operation holes 11e, 11e... are opened along the left and right side edges so as to correspond to the tips of each slot 11d of the left and right work holes 11c, 11c.... Note that while the work holes 11c and 11e are illustrated in FIG. 1 as vertically elongated rectangles and squares, respectively, they may have shapes other than those shown. Furthermore, the work holes 11c with slots 11d may be so-called "pot-shaped holes."

[0021] Steel reinforcing plates 13 are attached symmetrically to the upper and lower ends of the back surface of base plate 11. Low ribs 11f are formed on the back surface of the upper and lower ends of base plate 11, and each reinforcing plate 13 has an L-shaped cross section and an upright side 13a and an attachment side 13b. The tip edge of attachment side 13b is attached to rib 11f on the base plate 11 side.

[0022] The back surface material 12 is attached to the back surface side of the base plate 11 so as to cover almost the entire surface except for the upper and lower reinforcing plates 13, 13 and the left and right mounting pieces 11a, 11a. The thickness t of the back surface material 12 is set so as to exceed the upright sides 13a of the reinforcing plates 13 and the tips of the reinforcing ribs 11b of the base plate 11 (FIGS. 1(B) and (C)).

[0023] The installation and removal procedures for the base panel 10 are shown, for example, in Figures 2(A), (B) and 3(A), (B), respectively. However, in Figures 2 and 3, only a portion of the right end of the base plate 11 of the base panel 10, excluding the backing material 12, is shown, and only a portion of the right side of the left and right support posts 21, 21 for the C-channel-shaped partition device is shown as an example of the object to be fastened with screws to the base panel 10.

[0024] When attaching the base panel 10 to the posts 21 (FIG. 2(A)), first, the mounting pieces 11a of the base plate 11 are positioned by aligning the tips of the operation holes 11e and the slots 11d of the work holes 11c with the pilot holes 22a, which are pre-installed in a row on the front surface of each post 21. Next, the screws 22 are screwed into the pilot holes 22a on the posts 21 via the tips of the operation holes 11e and slots 11d (FIGS. 2(A) and 2(B)), thereby fastening the base plate 11 and attaching the base panel 10 to the posts 21. However, at this time, each screw 22 is screwed in to an appropriate depth so that the base panel 10 can move up and down along the front surface of the post 21.

[0025] When removing the base panel 10 from the posts 21, 21 (FIG. 3(A)), first, the entire base panel 10 is lifted along the front of each post 21 (in the direction of arrow K1 in the figure), and each screw 22 on the post 21 is moved relatively from the slot 11d to the working hole 11c and advanced. Next, when the base panel 10 is moved parallel to the front surface away from each post 21 (in the direction of arrows K2, K2 ... in the figure (B)), the heads of each screw 22 on the post 21 pass rearward through the working hole 11c, and the base panel 10 can be removed from the posts 21, 21.

[0026] The base panel 10 can be reattached to the posts 21, 21 using the screws 22, 22... (FIG. 3(B)) on each post 21. That is, when the base panel 10 is positioned so that the work holes 11c, 11c... align with the screws 22, 22... on the posts 21 and each mounting piece 11a is seated on the front surface of the post 21, the head of each screw 22 is inserted into the corresponding work hole 11c. Then, when the entire base panel 10 is lowered along the front surface of the posts 21, the neck of each screw 22 rises relatively and enters the slot 11d of the work hole 11c, and each screw 22 engages with the tip of each slot 11d, thereby attaching the base panel 10 to the posts 21, 21.

[0027] Similarly, before attaching the base panel 10 to the posts 21, 21, screws 22 can be screwed to a predetermined depth into the pilot holes 22a, 22a... on each post 21, and the base panel 10 can be attached using these screws 22, 22...

[0028] The base panel 10 can be used to form a partition panel 30 for a partition device (Fig. 4). However, Fig. 4(A) to (C) are each a schematic cross-sectional view showing the procedure for forming the partition panel 30, and for convenience, the lower and upper sides of each figure will be referred to as the front side and rear side, respectively, in the following description.

[0029] First, in accordance with the above-mentioned installation procedure, the base panel 10 is screwed to the front sides of the left and right support posts 21, 21 for the partition device with the screws 22, 22... (FIGS. 4(A) and (B)).

[0030] Next, a finishing material 31 such as tiles is adhered to the front surface of the base plate 11 of the base panel 10 via an adhesive 32 to form the partition panel 30 (FIG. 1C). The finishing material 31 can be extended to the front center of the left and right supports 21, 21, to form proper joints between adjacent partition panels. By adhering the finishing material 31 to the surface of the base panel 10 after it has been attached to the supports 21, 21, the relative relationship between the panels and adjacent partition panels can be aligned, easily achieving a neat overall appearance. However, the adhesive 32 may be replaced with double-sided adhesive tape. The finishing material 31 can also be adhered to the front surface of the base plate 11 before the base panel 10 is attached to the supports 21, 21.

[0031] If necessary, the partition panel 30 can be easily removed from the posts 21, 21 in accordance with the removal procedure described above without destroying the finishing material 31.

[0032] In Fig. 4, a partition panel 40 is attached to the rear side of the supports 21, 21. The partition panel 40 is made up of a front panel 41 made of, for example, a steel plate and a backing material 42 such as gypsum board. The partition panel 40 is fastened to the rear side of the supports 21, 21 via large and small fastening fittings 23, 24 (Figs. 4 and 5). Figs. 5(A) to 5(C) are respectively a schematic front view of the supports 21, 21 in Fig. 4(A) as seen from the front side, and a schematic side view of each support 21 as seen in the direction of arrows Y1 and Y2 in the same figure.

[0033] The locking fitting 23 is screwed to the side surface of the opening side of the support 21 so as to cross the opening 21a (Figs. 4(A) and 5(C)), and can lock the partition panel 40 with an upward-facing hook 23a protruding from the rear side of the support 21. On the other hand, the locking fitting 24 is attached to the side surface of the rear side of the support 21 close to the rear side of the support 21 via wing-shaped hooks 24b, 24b that are inserted into vertical slits 21b, 21b on the support 21 (Figs. 4(A), 5(A), (B)), and can lock the partition panel 40 with the upward-facing hook 24a protruding from the rear side of the support 21. Note that a plurality of locking fittings 23, 24 are provided at predetermined intervals in the vertical direction of each support 21.

[0034] The partition panel 30 forms appropriate joints with the adjacent partition panels 30, 40 and glass panel 50 via the support posts 21, and the surfaces of each panel are aligned to achieve a good appearance (Fig. 6). Note that Figs. 6(A) to 6(C) are schematic cross-sectional views of the main parts.

[0035] For example, in Figure 6(A), the partition panels 40, 30 on the front and rear sides of the support pillar 21 are adjacent to each other on the left and right. However, the locking fittings 23 for the front and rear partition panels 40, 40 have hooks 23a, 23a that protrude from the front and rear of the support pillar 21. Also, in Figure 6(B), the partition panels 30, 30 on the front side of the support pillar 21 are adjacent to each other on the left and right, and the partition panels 30, 40 on the rear side are adjacent to each other on the left and right. However, a connecting plate 25 that crosses the opening 21a is screwed to the side surface of the opening side of the support pillar 21.

[0036] In Figure 6(C), the front and rear partition panels 30, 40 on the left side of the support pillar 21 are adjacent to the glass panel 50 on the right side of the support pillar 21. The glass panel 50 has front and rear glass plates 51, and the glass plates 51 are incorporated into a frame body that combines one vertical frame 52 that is attached to the support pillar 21 by screws via cushioning materials 52a, 52a, a lower frame and an upper frame (not shown), and the other vertical frame 52 (not shown) via cushioning materials 53a, 53a... on the inside and outside of the periphery and glass retainers 53, 53.... However, the glass plates 51, 51 may also be made of synthetic resin plates or the like.

[0037] Furthermore, the height position of the surface of the partition panel 30 can be aligned with the surfaces of other partition panels 40 and glass panels 50 by appropriately setting the distance d (Figure 1(C)) between the surface side of the base plate 11 and the mounting piece 11a.

[0038] In the above description, the pillars 21 for the partition device shown in Figures 2 to 6 are installed vertically at predetermined intervals between the floor rails on the floor surface and the ceiling rails on the ceiling surface in the room of a building. However, the lower end of the pillar 21 is equipped with a height adjustment jack, and a telescopic bracket is interposed between the upper end and the ceiling rail in an extendable manner. In addition, the partition panel 30 can be supported from below by unillustrated receiving brackets attached to the lower end of each of the left and right pillars 21, 21. This is because the weight of the partition panel 30 tends to be large due to the finishing material 31. In addition to the C-channel shape shown in the figure, the pillars 21 may be rectangular or square in cross section, or may be groove-shaped or I-shaped in cross section. Other embodiments

[0039] The base panel 10 can be removably screwed to a base member such as lightweight steel on the wall of a building (not shown) in accordance with the installation procedure shown in FIG. 2, and then a finishing material 31 such as tiles can be attached to the surface of the base board 11 using adhesive 32 or double-sided adhesive tape in accordance with FIG. 4(C) to form a wall panel (not shown). The wall panel can be easily attached and removed in the same manner as the partition panel 30. The base member may be made of any material, including wood, as long as it has appropriate strength and can be fastened with screws 22. It is also possible to omit the base member and screw the base panel 10 directly to the wall of the building. [Industrial Applicability]

[0040] The present invention can be widely and suitably applied to buildings for all purposes where it is required to appropriately reuse finishing materials such as tiles without destroying them. [Explanation of symbols]
