Then, as shown in FIG. 2 (a), the surface material 3 includes a front wall portion 7 on the front side and left and right side end portions of the surface material 3 (the left side end portion is shown in FIG. 2 (a)). Are respectively formed on the back surface side by being bent into a substantially U-shape, and a side wall portion 8 and a back wall portion 9.

  At the left and right ends of the surface material 3, the vertical rail 4 is located in the space 11 between the front wall portion 7 and the back wall portion 9, in other words, the space surrounded by the front wall portion 7, the side wall portion 8, and the back wall portion 9. It is inserted from the side and fixed to the surface material 3.

  As shown in FIG. 2A, the side wall edge of the back wall portion 9 is cut out to the side, and the cutout 12 extends in the vertical direction on the back wall portion 9. . A part 13 in the vertical direction of the notch 12 is further deeply cut out to the side, and the notch 12 is formed in the vertical beam 4 and is a slit 17 (FIG. It is formed along the side edge of b).

  As shown in FIG. 2A, convex portions (for example, dowels) 16 are formed in the back wall 9 at positions above and below the notch 12 and in the vicinity of the notch 12, respectively. ing. The convex portion 16 engages with a hole or a concave portion 22 (see FIG. 2B) formed in the vertical rail 4 described later. Although not shown in the drawings, a configuration in which a convex portion is formed on the vertical rail 4 and a hole or a concave portion is formed on the back wall portion 9 may be employed.

The narrow width portion 19 is formed vertically with the wide width portion 18 in between, and has a narrow lateral width so that the protrusion 29 cannot be inserted or removed. The notch 12 in the back wall portion 9 is formed by notching a portion that overlaps the slit 17 of the vertical rail 4.

  Holes or recesses 22 are respectively formed at positions above and below the slit 17 of the vertical rail 4 and in the vicinity of the notch 12. The hole or recess 22 engages with the protrusion 16 formed in the back wall 9 described above. In addition, as above-mentioned, the structure by which a hole or a recessed part is formed in the back wall part 9, and a convex part is formed in the vertical beam 4 may be sufficient.

(Function)
In order to clarify the configuration and characteristics of the wall panel 1 of this embodiment, the assembly process and operation will be described. In order to further clarify the characteristics of the wall panel 1, a connection structure in which two wall panels 1 are connected adjacent to each other will be described as an example of use.

  When assembling the wall panel 1, as shown by the arrow in FIG. 3A, it is pushed against the elasticity 11 of the back wall 9 against the gap 11 between the front wall 7 and the back wall 9 of the surface material 3. Insert the vertical rail 4 from the side to open. And the convex part 16 of the back wall part 9 is engaged with the hole or recessed part 22 formed in the vertical beam 4 and positioned, and the vertical beam 4 is positioned between the front wall part 7 of the surface material 3 and the back wall part 9. 11 to fix.

  As a result, as shown in FIG. 3B, the vertical beam 4 is attached to the side end portion of the surface material 3. Further, the plate member 2 serving as a core is attached to the back surface side of the surface material 3 between the left and right vertical bars 4. In this way, the wall panel 1 as shown in FIGS. 1A and 1B is assembled.

  In the wall panel 1, the convex portion 16 of the back wall portion 9 of the surface material 3 is engaged with the hole or the concave portion 22 formed in the vertical rail 4, and the gap between the front wall portion 7 and the back wall portion 9 of the surface material 3 is. Since the vertical beam 4 is sandwiched and fixed to 11, the vertical beam 4 is not easily detached from the surface material 3.

  Next, a connection structure for connecting two adjacent wall panels 1 will be described. As shown in FIG. 4A, a connecting member 25 as shown in FIGS. 4B and 4C is used to connect two adjacent wall panels 1 together. The connecting member 25 is formed by bending a metal material into a shape as shown in FIGS. 4B and 4C.

  The connecting member 25 includes a left and right contact portion 26, a non-contact portion 27 protruding rearward from the contact portion 26 between the left and right contact portions 26, and the lateral width direction outer side with respect to the contact portion 26. The right and left rib portions 28 are formed. As shown in FIGS. 4 (c) and 5 (b), protrusions 29 projecting forward are provided on the front surfaces of the left and right contact portions 26, respectively.

  The projecting portion 29 is formed of a neck portion 32 fixed to the contact portion 26 and a large-diameter portion 33 that expands in a tapered shape toward the front via the neck portion 32. The maximum diameter of the large diameter portion 33 is smaller than the width of the wide width portion 18 of the slit 17 and larger than the width of the narrow width portion 19.

  When two adjacent wall panels 1 as shown in FIG. 4A are connected by the connecting member 25, the large-diameter portions 33 of the left and right protrusions 29 of the connecting member 25 are connected to the slit 17 of the vertical beam 4. The width portion 18 is inserted into the slit 17, the connecting member 25 is moved downward, and the neck portion 32 of the projection portion 29 is fitted to the narrow width portion 19.

  Then, the two vertical bars 4 of the two adjacent wall panels 1 come into contact with the left and right contact portions 26 of the connecting member 25 and are fixed to the connecting member 25, respectively. 25 is connected. As a result, as shown in FIGS. 5A and 5B, a connection structure in which two adjacent wall panels 1 are connected to each other in one vertical plane by the connecting member 25 is obtained.

  The protruding portion 29 of the connecting member 25 is fitted into the connecting member fitting slit 17, and the force applied to the connecting member 25 in this connection structure is large, particularly in the vicinity of the slit 17 of the vertical rail 4 through the protruding portion 29. Works. For this reason, there is a risk that the vertical beam 4 may come off from the surface material 3 or the surface material 3 may float with respect to the vertical beam 4.

  However, the wall panel 1 of this embodiment is provided with holes or recesses 22 formed in the vertical beam 4 in the vicinity of the upper and lower sides of the connecting material fitting slit 22, and the back wall of the surface material 3 corresponding to this position. Since the convex portion 16 of the portion 9 is provided, the vertical rail 4 is firmly positioned and fixed to the surface material 3 in the vicinity of the slit 17. Therefore, the vertical beam 4 is prevented from being detached from the surface material 3 and the surface material 3 is prevented from floating with respect to the vertical beam 4.

  Between the two adjacent wall panels 1 connected to each other, as shown in FIG. 5B, a joint material 34 for water stoppage is inserted from the front (bathroom side). The fins 35 projecting to the left and right of the joint material 34 abut against the side wall portion 8 of the surface material 3 of the wall panel 1 and exhibit a water stop function. As described above, water is stopped by the fin 35 of the joint material 34, but the water stopped by the fin 35 may cause rust on the side wall 8 by contacting the side wall 8.

  However, since the surface of the side wall 8 of the wall panel 1 of this embodiment is coated with resin and has rust prevention properties, the occurrence of rust is suppressed even when water contacts the side wall 8.

(Modification)
Hereinafter, modification 1 of the surface material and the vertical rail in the wall panel 1 of the present embodiment will be described. FIG. 6A is a horizontal cross section showing a state in which the vertical beam 46 of the first modification is inserted and fixed in the gap between the front wall portion 42 and the rear wall portion 43 of the surface material 41 of the first modification. The figure is shown.

  In the first modification, the back wall 43 of the surface material 41 is bent forward to form a convex portion 47, and correspondingly, a concave portion 48 is formed on the back surface of the vertical beam 46. Is formed. Therefore, when the vertical beam 46 is inserted from the side into the gap between the front wall part 42 and the back wall part 43 of the surface material 41, the convex part 47 of the back wall part 43 engages with the concave part 48 of the vertical beam 46, Positioned and fixed.

  FIG. 7B is a diagram for explaining a second modification of the surface material and the vertical rail in the wall panel of the present embodiment, and in the gap between the front wall portion 52 and the back wall portion 53 of the surface material 51 of the second modification. FIG. 10 is a horizontal sectional view showing a state in which a vertical beam 56 of Modification 2 is inserted and fixed.

  In this modified example 2, the front end portion 54 of the back wall portion 53 of the surface material 51 is bent forward at a right angle to form a convex portion 57, and correspondingly, a hole 58 is formed on the back surface of the vertical beam 56. Is formed. Therefore, when the vertical beam 56 is inserted from the side into the gap between the front wall portion 52 and the back wall portion 53 of the surface material 51, the convex portion 57 of the back wall portion 53 engages with the hole 58 of the vertical beam 56, Positioned and fixed.

  FIGS. 7C and 7D illustrate a third modification of the surface material and the vertical rail in the wall panel of the present embodiment. FIG.7 (c) shows the state which inserts the vertical crosspiece 66 into the gap | interval of the front wall part 62 and the back wall part 63 of the surface material 61 of a wall panel from the side like the arrow, FIG.7 (d) The horizontal cross section which shows the state which the vertical crosspiece 66 was inserted and fixed to the clearance gap between the front wall part 62 and the back wall part 63 of the surface material 61 is shown.

  In the third modified example, a chamfered portion 69 is formed at a part of a corner portion of the vertical beam 66 facing a corner portion formed by the front wall portion 62 and the side wall portion 68, and the front wall portion 62 of the surface material 61 is formed. And the surface of the vertical beam 66 (front side surface), an adhesive 67 is applied to fix the vertical beam 66 to the surface material 61 more firmly.

  When the adhesive 67 is applied, a lump of the adhesive 67 is attached to the back surface of the front wall 62 as shown in FIG. 7C, and the vertical beam 66 is inserted from the side as indicated by an arrow. Then, as shown in FIG. 7 (d), the adhesive 67 is applied to the gap between the front wall portion 62 and the vertical rail 66 while extending.

  When the adhesive 67 is applied in this way, if the vertical beam 66 is inserted between the front wall part 62 and the back wall part 63, the adhesive is bonded to the gap between the side wall part 68 of the surface material 61 and the vertical beam 66. There is a problem that the agent 67 flows in and stays and cannot be inserted all the way to the extent that the vertical beam 66 contacts the side wall 68.

  However, in the modified example 3, as described above, the chamfered portion 69 is formed at a part of the corner portion of the vertical beam 66 facing the corner portion formed by the front wall portion 62 and the side wall portion 68. When the vertical beam 66 is inserted into the gap of the back wall portion 63 from the side, the chamfered portion 69 functions as a reservoir for the adhesive 67. Therefore, the problem that the adhesive 67 flows into and stays in the gap between the side wall portion 68 and the vertical beam 66 and the vertical beam 66 cannot be sufficiently inserted can be suppressed.

  As mentioned above, although the form for implementing the wall panel which concerns on this invention was demonstrated based on the Example, this invention is not limited to such an Example, The technical statement described in the claim It goes without saying that there are various embodiments within the scope of the matter.
