Connected together. Moreover, the panels (refer FIG. 1 (a), (b)) attached adjacently in the direction orthogonal to the adjacent direction of a panel are connected by the connection member 5 inserted by the connection recessed part 4. FIG.
This will be described in detail below.

First, the configuration of each member for connecting the panel 1 and the panel 1 will be described.
The panel 1 is a wall panel that is a substantially rectangular flat body in plan view, and covers a substantially entire area of the wall surface 20 so as to substantially cover the wall surface 20 of the existing wall body with a plurality of sheets arranged side by side. Are arranged along the wall surface 20. The plurality of panels 1 have substantially the same width.
The example shown here is an example in which a protruding portion 21 protruding in the forward direction, that is, a beam is formed on the wall surface 20, and in this case, the panel 1 C is attached to the wall surface 20, and the front surface portion 21 a of the protruding portion 21 and Panels 1A and 1B are attached to each of the side surface portions 21b.
The dimensions and the number of attached panels 1 are set according to the dimensions of the wall surface 20 and the protruding portion 21.

The panel 1 in the figure shows a panel with heat insulation as an example, but is not limited to this, and may be formed from a wood-based material, gypsum board, or the like. Moreover, the functional panel provided with soundproofing property, deodorizing property, etc. may be sufficient. In the figure, 12 indicates a main body of the panel 1, and 13 indicates a side surface of the panel 1.
The panel 1 includes a surface plate 10 and a resin foam 11 as shown in FIGS. 3A and 3B, and a vacuum heat insulating material (not shown) is accommodated on the back side of the surface plate 10, A resin foam 11 is filled around the vacuum heat insulating material, and the vacuum heat insulating material is covered with the resin foam 11.

The surface plate 10 is formed by coating a metal plate 10a functioning as a core material with a resin 10b. As the metal plate 10a, a steel plate or the like is used, a galvanized steel plate, a coated steel plate, a tin-plated steel plate, or the like. May be used. As the resin 10b covering the metal plate 10a, a synthetic resin such as a vinyl chloride resin is used. The synthetic resin may be a thermoplastic resin or a thermosetting resin. The synthetic resin is not limited to vinyl chloride resin, and other synthetic resins may be used.
Both end portions of the metal plate 10a, specifically both left and right ends, are respectively bent as shown in FIG.

The metal plate 10a on the one end 1a side of the panel 1 is bent in a substantially vertical direction from the main body portion 12 toward the wall surface 20 (L-shaped in a plan view), and around the bent metal plate 10a. The resin 10b is covered to form the fitting convex portion 2.
More specifically, the fitting convex portion 2 is formed at a position slightly spaced outward from the side surface portion 13 on the one end 1 a side of the panel 1, and thereby the side surface portion 13 on the one end 1 a side of the panel 1. A connecting space 19 is formed in the gap with the fitting convex portion 2.
That is, the formation position of the fitting convex portion 2 is provided in the vicinity of the fitting concave portion 3 when the fitting convex portion 2 is fitted into the fitting concave portion 3 of the panel 1 disposed adjacent thereto. It is set as the position where the connection recessed part 4 which does not interfere. Therefore, when the panels (panel 1C and panel 1D in the illustrated example) are fitted together, the coupling recess 4 is accommodated in the coupling space 19 formed in the gap between the side surface portion 13 and the fitting projection 2, so that the coupling recess The panel 1 </ b> D can be fitted to the wall surface 20 from the front without disturbing 4.
More specifically, when the panel 1D is fitted to the panel 1C, the end portion 13a (see FIG. 3B) on the back surface side (wall surface 20 side) of the side surface portion 13 on the one end 1a side of the panel 1 is fitted. It is comprised so that it may contact | abut to the wall side protrusion part 18 mentioned later. That is, the end portion 13a on the back surface side of the side surface portion 13 on the one end 1a side is provided so as to form a gap in which the wall surface protruding portion 18 can be interposed. Therefore, when fitting the fitting convex portion 2 of the panel 1D into the fitting concave portion 3 of the panel 1C from the front with respect to the wall surface 20, the end portion 13a is pushed to a position where the wall side protruding portion 18 abuts. If it goes, the fitting convex part 2 can be firmly fitted to the fitting concave part 3.

The metal plate 10a on the other end 1b side of the panel 1 is bent into a substantially U shape in plan view so as to have a concave shape with an opening in front of the wall surface 20, and a thin resin 10b is formed around the bent metal plate 10a. Is coated. Accordingly, the side surface portion 13 on the other end 1b side, the extending portion 15 extending outward from the side surface portion 13 in the substantially vertical direction, and facing the side surface portion 13 and being substantially vertical from the extending portion 15 A fitting recess 3 into which the above-described fitting protrusion 2 is fitted is formed by the upright portion 16 extending in the direction.
More specifically, as shown in FIG. 3 (b), the fitting convex portion 2 fitted into the fitting concave portion 3 is guided between the main body portion 12 and the side surface portion 13 on the other end 1b side. A chamfered portion 14 having an inclined surface is formed. In addition, a guide portion 16a having an inclined surface is formed at the end portion of the upright portion 16 in order to guide the fitting convex portion 2 so as to be easily fitted into the fitting concave portion 3 in the same manner as the chamfered portion 14. Has been. Reference numeral 16b denotes a locking projection for locking the fitting projection 2 so that it does not easily come off the fitting recess 3. When the fitting projection 2 is fitted, the locking projection 16b is fitted to the fitting projection. After the protruding portion 2a formed on the portion 2 gets over, it is in a fitted state (see FIG. 3B).
The locking protrusions 16b may be formed on the protrusions in the vertical direction (or the horizontal direction depending on the orientation of the panel 1), or may be provided with an appropriate interval. Good.

The fitting recess 3 is opened on the front side so as to receive the fitting protrusion 2 protruding toward the wall surface 20, whereby the fitting protrusion 2 and the fitting recess 3 are located with respect to the wall surface 20. And can be fitted from the front. When the panels 1C and 1C are fitted to each other, the fitting convex portion 2 is smoothly guided into the fitting concave portion 3 due to the presence of the guide portion 16a and the chamfered portion 14.
Then, by fitting the fitting convex portion 2 and the fitting concave portion 3, the panel 1C attached adjacent to the linear direction (see d1 in FIG. 3A) connecting the one end 1a side and the other end 1b side, 1D can be connected. In other words, in the illustrated example, the panels 1C and 1D arranged side by side in the horizontal direction are connected by fitting the adjacent fitting convex portion 2 and fitting concave portion 3 together.

On the further outward side of the upright portion 16 (on the right side in FIG. 3B), a connecting recess 4 is formed to open to the side of the panel 1. That is, in the illustrated example, the connecting recess 4 is formed on the other end 1b side where the fitting recess 3 is formed.
The connecting recess 4 includes an upright part 16, a protruding part 17, and a wall side protruding part 18. The protruding portion 17 and the wall-side protruding portion 18 are formed so as to protrude in a substantially vertical direction with respect to the upright portion 16, and the protruding portion 17 has a holding portion 17 a formed in a slightly bowl shape in plan view. Is formed. The projecting portion 17 and the wall-side projecting portion 18 face each other and are substantially parallel to each other, and are formed between the projecting portion 17 and the wall-side projecting portion 18. After being fitted, it is firmly held by the holding part 17a.
Thus, the panel (1A-1C) attached adjacent to the direction (refer d2 of FIG. 2 (a)) orthogonal to the adjacent direction of panel 1C, 1D is the connection member inserted by the connection recessed part 4. FIG. 5 is connected. That is, in the illustrated example, the panels 1 </ b> A, 1 </ b> B, and 1 </ b> C arranged in parallel in the vertical direction are connected by the connecting member 5 fitted in the connecting recess 4.

  The structure and shape of the panel 1 are not limited to the illustrated example, and the formation of the fitting convex portion 2, the fitting concave portion 3, and the connecting concave portion 4 is not limited to the illustrated example. For example, in the illustrated example, the positions of the fitting convex portions 2 and the fitting concave portions 3 formed on the left and right ends of the panel 1 may be reversed, or the connecting concave portion 4 is formed on the side where the fitting convex portions 2 are formed. May be provided.

  The connecting member 5 is made of a metal material, a hard resin material, or the like, and is not limited to a prismatic shape as in the illustrated example, and may be a circular cross section. Moreover, although the connection member 5 of the example is L-shaped in order to connect the panels 1A and 1B arranged at the place where the protruding portion 21 is provided on the wall surface 20, it is not limited to this. For example, when connecting the panels arranged in a place without the protruding portion 21, the connecting member 5 may be linear (not shown). Furthermore, it may be substantially Z-shaped so that the three panels arranged on the protruding portion 21 and the like can be connected by a single connecting member 5.

Next, an example of the construction procedure of the panels 1A to 1C and the panels 1C and 1D will be described with reference to the drawings.
The structure around the wall surface 20 shown in FIG.
In FIG. 2A, 22 is a ceiling, 23 is a peripheral edge, 24 is a frame on the wall that is screwed to a joist (not shown) of the ceiling 22, 25 is a floor surface, 26 is a baseboard, and 27 is a floor surface 25. It is a frame under the wall screwed to. The peripheral edge 23 is screwed or tacked to the frame 24 on the wall, and the baseboard 26 is tacked to the frame 27 below the wall.
The protruding portion 21 refers to a portion protruding forward from the wall surface 20, and in the drawing, 21 a is a front surface portion of the protruding portion 21, and 21 b is a side surface portion. When the projecting portion 21 is a beam, 21b corresponds to the bottom of the beam.
Below, the construction point of panel 1A-1C installed in the wall surface 20 like Fig.2 (a) is demonstrated. Here, the connecting member 5 that connects the panels 1A and 1B attached to the front surface portion 21a and the side surface portion 21b of the protruding portion 21 is referred to as a first connecting member 5A. Moreover, let the connection member 5 which connects the panels 1B and 1C attached to the side part 21b and the wall surface 20 be the 2nd connection member 5B.

First, the panel 1C is attached to the wall surface 20, the panel 1B is attached to the side surface portion 21b, and the panel 1A is attached to the front surface portion 21a. An adhesive is applied to each of the back surfaces of the panels 1A to 1C. Of course, an adhesive may be applied to an object to be attached (for example, the wall surface 20), and the panels 1A to 1C may be bonded.
Then, the first connecting member 5A and the second connecting member 5B are sequentially fitted into the connecting recess 4 from the side of the bonded panels 1A to 1C. The procedure at this time may be inserted from the second connecting member 5B that connects the panel 1C and the panel 1B, or may be inserted from the first connecting member 5A that connects the panel 1A and the panel 1B. .

When the installation of the panels 1A to 1C arranged side by side in the vertical direction is completed in this way, the panels are sequentially arranged in the row. For example, if the panel 1D attached to the side of the panel 1C attached to the wall surface 20 is attached so as to fit the fitting convex part 2 into the fitting concave part 3 of the panel 1C from the front, the panel 1C is placed between the panel 1C and the panel 1D. Can be attached with high accuracy without causing a large gap. At this time, the connection recessed part 4 is stored in the connection space 19, and the fitting recessed part 3, the connection recessed part 4, and the 2nd connection member 5B are covered with the panel 1D arranged in parallel. Therefore, the second connecting member 5 is not exposed after the construction, and the appearance is good. Of course, the first connecting member 5 </ b> A is also covered by the adjacent panel.
After that, the same procedure is repeated, and after attaching all the panels 1, the baseboard 26 and the peripheral edge 23 are attached. Then, an L-shaped cover 6 may be adhered to the corners of the panels 1A and 1B and the corners of the panels 1B and 1C in a cross-sectional view so as to hide the gaps between the panels 1A, 1B, and 1C ( (Refer FIG.2 (b)).

  According to the above, the panels 1 </ b> A to 1 </ b> D are connected by the first and second connecting members 5 </ b> A and 5 </ b> B in the vertical direction and in the horizontal direction by fitting the fitting convex portion 2 and the fitting concave portion 3. Therefore, it is possible to prevent the panels 1A to 1D from partially falling. For example, even if the adhesiveness of the panel 1B bonded to the side surface portion 21b corresponding to the underside of the beam declines, the panel 1B is connected by the first and second connecting members 5A and 5B. Can be prevented. 2A, the upper end of the panel 1A is fixed by a peripheral edge 23, and the lower end of the panel 1C is fixed by a baseboard 26. The peripheral edge 23 and the baseboard 26 are members that are long in the horizontal direction, and fix the upper end or lower end of the plurality of panels. In addition to the connecting action by the first and second connecting members 5A and 5B, The panels 1A and 1C can be firmly fixed to the protruding portion 21 or the wall surface 20.

Moreover, since the 1st and 2nd connection member 5A, 5B can be inserted in the connection recessed part 4 after attaching panel 1A-1C to the wall surface 20 and the protrusion part 21, construction is very easy.
Furthermore, even if the protruding portion 21 is present on the wall surface 20 as described above, the adjacent panels 1A to 1C can be easily and reliably connected by the first and second connecting members 5A and 5B.
If the panel 1 connected by a plurality of connecting members, such as the first and second connecting members 5A and 5B, that is, the one connecting member 5 is connected to two panels, the protrusion 21 protrudes. Even if the width is different or there is a variation in dimensions, it does not hinder the connection. That is, when the three panels 1 arranged at the place where the protruding portion 21 is located are connected by one connecting member as shown in the figure, the connecting member 5 is designed in accordance with the protruding width of the protruding portion 21. There must be. However, if a plurality of L-shaped connecting members 5 are prepared as shown in the figure, it is possible to connect well without considering the protruding width of the protruding portion 21.
Further, when the panel 1 and the wall surface 20 are bonded with an adhesive as described above, the panel 1 can be brought into close contact with the wall surface 20, and the panel 1 can be easily attached to the wall of the RC structure that cannot be screwed. It becomes possible.

Note that the protruding portion 21 is not limited to a portion protruding as a beam, and may be a portion where a pipe is broken or a place where a pillar is present. Moreover, if it is the above-mentioned panel connection structure, it is not limited to the case where there is a protruding portion 21 in the vicinity of the ceiling as shown in the figure, but can also be applied to the case where there is a protruding portion on the floor surface 25 side.
In addition, the configuration, shape, number of installations, and the like of the panel 1 (1A to 1D), the fitting convex portion 2, the fitting concave portion 3, the connecting concave portion 4, the connecting member 5, and the wall surface 20 according to the above-described embodiment are illustrated in the drawings. It is not limited.
