Description

  The present invention relates to a wall panel and a connection structure of the wall panel used in a bathroom or the like.

  Conventionally, in a wall panel used in a bathroom or the like, the upper surface of the surface material is formed by bending horizontally, and the end of the wall panel is inserted in order to insert a connecting material connected with the adjacent wall panel from above. There is known a configuration in which a part of the upper surface is cut off in a part or the like (Patent Documents 1 and 2).

  Also, conventionally, a configuration is known in which two wall panels adjacent to each other in the same plane are connected via a connecting member. FIG. 6 is a connecting structure of wall panels and wall panels developed by the applicant prior to the present invention, and this configuration is referred to as a comparative example in the present specification.

  In the connection structure 49 of the wall panel of Comparative Example 1 shown in FIGS. 6A and 6B, the wall panel 50 includes the surface material 51, the reinforcing material 52 covered with the surface material 51, and the left and right of the wall panel 50. And a longitudinal bar 53 provided at the end. The back surface side of the reinforcing material 52 is covered with a back surface material 54.

  The upper surface 56 is formed on the upper surface of the surface material 51 so as to be horizontally bent to the back surface side. Although not shown, the lower surface is similarly formed with a lower surface bent horizontally to the rear surface side.

  Adjacent two wall panels 50 are connected toward the front surface of the surface material 51 by a connecting material 57 having a substantially concave horizontal cross section. In order to connect or separate the two adjacent wall panels 50, the connecting member 57 is inserted from above or pulled out upward. For this purpose, the left and right end portions of the upper surface 56 are cut away to form notches 58.

  As shown in FIG. 6B, the notch 58 is formed in the left-right direction up to the gap 61 between the vertical beam 53 and the reinforcing member 52, and the upper surface of the vertical beam 53 is exposed. Although not shown, similar notches are formed at the left and right end portions of the lower surface, and the lower surface is exposed.

  In the connecting member 57, protrusions 62 are formed on the left and right toward the front surface of the surface member 51, and the left and right protrusions 62 are respectively fitted in grooves (not shown) formed in the left and right wall panels 50. By being fixed to the wall panel 50, the two wall panels 50 are connected.

  In the connection structure 64 of the wall panel of Comparative Example 2 shown in FIG. 6C, the wall panel 65 is substantially the same as that of Comparative Example 1, but the space where the reinforcing member 52 and the vertical crosspiece 66 are attached at the left and right end portions.

Although not shown, the notch 16 of the lower surface 15 may be formed to the lower part of the reinforcing member 3 so that a part of the lower part of the reinforcing member 3 is exposed.

  By the way, although the wall panel 1 has the clearance gap 20 between the vertical crosspiece 4 and the reinforcing material 3, the part of this clearance gap 20 in the wall panel 1 is weak in strength compared with other parts. Further, the portion of the notch 11 of the upper surface 10 of the surface material 2 (mainly the corner 12 of the notch) and the portion of the notch 16 of the lower surface 15 of the surface material 2 (mainly the corner 17 of the notch) It is weak in strength compared with the part of. It is not preferable from the point of view of the strength of the wall panel 1 that these weak parts in strength overlap.

  Therefore, in the wall panel 1 of the present invention, as shown in FIGS. 1 (b) and 2 (b), the position of the notch 11 on the upper surface 10 and the position of the notch 16 on the lower surface 15 are on the same vertical straight line. It is not formed. In addition, the notch 11 of the upper surface 10 and the notch 16 of the lower surface 15 are formed at the position of the gap 20 between the vertical crosspiece 4 and the reinforcing member 3 so as not to go.

  In short, the feature of the wall panel 1 of the present invention is that the position of the notch 11 of the upper surface 10 of the surface material 2 and the position of the notch 16 of the lower surface 15 are shifted in the left and right direction. It is formed so as not to come to the position of the gap 20 between the vertical crosspiece 4 and the reinforcing member 3.

  As shown in FIGS. 1 (b) and 2 (a), the left and right side ends of the front surface 8 of the surface material 2 (the side end on the left side is shown in FIG. 2 (a)) The side surfaces 23 and the back surface 24 are formed by being bent in a U-shape. The vertical bars 4 are inserted from the side into the spaces 25 surrounded by the front surface 8, the side surfaces 23 and the back surface 24 at the left and right end portions of the surface material 2 and fixed to the surface material 2.

  As shown in FIG. 1A, the side edge of the back surface 24 is cut out in the side surface on the back surface 24 so that a notch 28 extends in the vertical direction. A portion of the notch 28 in the vertical direction is notched deeper toward the side, and is formed along the side edge of the slit 5 for coupling material fitting described later formed in the longitudinal bar 4 There is.

  As shown in FIG. 1 (b) and FIG. 2 (a), the longitudinal bar 4 is formed in a substantially square pipe shape in cross section. A slit 5 for connecting material fitting is formed on the wall on the back side of the longitudinal bar 4. The slit 5 is composed of a wide portion 29 and a narrow portion 30.

  The wide width portion 29 is formed at the central portion in the vertical direction of the slit 5 and is formed in a wide lateral width so that the projection 34 of the connecting member 33 described later can be inserted and removed. The narrow portion 30 is formed on the upper and lower sides of the wide portion 29 and has a narrow lateral width so that the projection 34 can not be inserted and removed.

  As shown in FIGS. 1 (a) and 2 (b), in the back surface 24 of the surface material 2 and the back surface of the longitudinal beam 4, the fixing portion 37 at positions above and below the notch 28 and the slit 5 The material 2 and the longitudinal bars 4 are fixed to each other. The fixed portion 37 is formed by engaging a convex portion (for example, a dowel) formed on the back surface 24 of the surface material 2 with a hole or a concave portion formed on the vertical crosspiece 4.

(Connection structure)
The connection structure 40 of the wall panel 1 according to the present invention will be described below with reference to FIGS. As shown in FIG. 2 (b), two adjacent wall panels 1 arranged in the same vertical plane are connected via a connecting member 33.

  The connecting member 33 is formed by bending a metal material into a shape as shown in FIGS. 3 (a) and 3 (b). The connecting member 33 has a non-contacting portion 42 protruding rearward from the contact portion 41 between the left and right contact portions 41 and the left and right contact portions 41, and a lateral width direction outer side with respect to the contact portion 41. And the left and right rib portions 43 formed thereon.

  As shown to FIG. 5 (a), (b), the side end wall 45 of the connection material 33 which comprises a part of rib part 43 ahead [the front part 8 of the surface material 2] rather than the contact part 41 In the connection structure 40 in which the two wall panels 1 are connected by the connection member 33, the two wall panels 1 are formed to extend below the upper surface 10 of the facing 2.

  The front end 46 of the side end wall 45 is notched from the top to form a notch 47, as shown in FIG. 3 (b). When moving the connecting member 33 upward in order to disassemble the two wall panels 1 from the state where the two wall panels 1 are connected by the connecting member 33, the side end wall 45 has a width w in the front-rear direction of the notch 47 The dimensions are set so as not to abut on the upper surface 10 of the surface material 2.

  As shown in FIG. 3A, on the front surfaces of the left and right abutment portions 41, protrusions 34 respectively projecting forward are provided. The projecting portion 34 is formed of a neck portion 35 fixed to the abutting portion 41 and a large diameter portion 36 which tapers forward through the neck portion 35. The maximum diameter of the large diameter portion 36 is smaller than the width of the wide portion 29 of the slit 5 and larger than the width of the narrow portion 30.

  The connection structure 40 of the two wall panels 1 is shown in FIGS. 4 and 5. In the two wall panels 1, the two vertical bars 4 abut the left and right abutment portions 41 of the connecting member 33, The large diameter portions 36 of the left and right projections 34 of the connecting member 33 are fitted to the narrow portions 30 of the slits 5 of the crosspiece 4 so that the connecting members 33 are fixed to each other via the connecting member 33. It will be in the connected state. The joint material 48 is inserted into the gap between the two wall panels 1 to shut off water.

(Action)
In order to further clarify the features of the wall panel 1 and the connection structure 40 of the wall panel 1 according to the present invention having the above configuration, the operation and the like will be described.

  The upper end and the lower end of the surface material 2 of the wall panel 1 are bent to the back surface side to form the upper surface 10 and the lower surface 15 as described above, and the left and right ends of the upper surface 10 and the lower surface 15 respectively The notch 11 and the notch 16 are formed in this.

  When the notches 11 and 16 are formed in this manner, when an external force is applied to the wall panel 1, the external force is concentrated in the vicinity of the corner portions 12 and 17 of the notches 11 and 16, and the surface material 2 is buckled. It becomes easy to be damaged. In particular, in the configuration in which the notches 11 and 16 are formed up to the position of the gap 20 between the longitudinal bar 4 and the reinforcing member 3, the support strength of the longitudinal bar 4 or the reinforcing member 3 is reduced. , Easy to break.

  In the wall panel 1 of the present invention, as shown in FIG. 1 (b) and FIG. 2 (a), the notches 11 respectively provided at the left and right ends of the upper surface 10 The vertical crosspiece 4 or the reinforcing member 3 is present at the position of the corner 12 of the notch 11 so that the wall panel 1 is formed by the notch 11 of the upper surface 10. There is no decrease in the strength of the

  Similarly, as shown in FIGS. 1B and 2A, in the wall panel 1 of the present invention, the notches 16 respectively provided at the left and right end portions of the lower surface 15 serve as a lower portion or reinforcement of the vertical beam 4. Since the vertical rail 4 or the reinforcing member 3 is present at the position of the corner 17 of the notch 16 so that the lower part of the material 3 is formed by being cut away, the wall 16 is formed by the notch 16 of the lower surface 15 The strength of the panel 1 does not decrease.

  Furthermore, in the wall panel 1 of the present invention, as shown in FIGS. 1 (b) and 2 (a), the position of the notch 11 on the upper surface 10 and the position of the notch 16 on the lower surface 15 are on the same vertical line. However, they are formed to be shifted in the left and right direction.

  With such a configuration, the corner 12 of the notch 11 on the upper surface 10 where the stress mainly concentrates and the corner 17 of the notch 16 on the lower surface 15 mutually shift in the left-right direction. Therefore, the surface material 2 is less likely to be broken.

  In the case where two adjacent wall panels 1 as shown in FIG. 2B are connected by the connecting member 33, the large diameter portions 36 of the left and right projections 34 of the connecting member 33 are formed by the slits 5 of the vertical rail 4. Then, the connecting member 33 is moved downward to fit the large diameter portion 36 of the projection 34 into the narrow portion 30.

  Then, the two vertical bars 4 of the two wall panels 1 adjacent to each other abut on the left and right abutment portions 41 of the connecting member 33 and are fixed to the connecting member 33, respectively. It will be connected via.

  Thus, as shown in FIGS. 4 (a), (b), 5 (a) and 5 (b), the two adjacent wall panels 1 are connected by the connecting member 33 in one vertical plane. The obtained connection structure 40 is obtained.

  When the two wall panels 1 connected are separated, the connecting member 33 is moved upward from the connected state as shown in FIGS. 4 and 5. Then, since the projection 34 moves from the narrow portion 30 to the wide portion 29 of the slit 5 of the longitudinal bar 4, the projection 34 can be extracted through the wide portion 29 and the connecting member 33 can be removed from the wall panel 1 . Thereby, the two connected wall panels 1 can be separated.

  By the way, although the left and right side end walls 45 of the connection member 33 in the connection structure 40 of the present invention form a part of the rib 43, the side end walls 45 extend along the end of the longitudinal bar 4 forwardly. The strength of the connecting member 33 as a whole can be increased. A notch 47 is formed at the front end 46 of the side end wall 45 of the connecting member 33 from the upper end.

  When connecting the two wall panels 1 with the connecting member 33 or disassembling, it is necessary to move the projection 34 of the connecting member 33 in the slit 5. Even in such a case, cutting is performed. Since the notches 47 are formed, the connecting member 33 can be moved in the vertical direction without being restrained by the upper surface 10 of the surface member 2.

  As mentioned above, although the form for carrying out the connection structure of the wall panel concerning the present invention and the wall panel was explained based on the example, the present invention is not limited to such an example, and claims It goes without saying that there are various embodiments within the scope of the technical matters described in.

  Since the wall panel and the connection structure of the wall panel according to the present invention are configured as described above, they can be applied as walls used in various applications such as for structural parts and partitions of various places of a building.
