In other words, the angle θ between the upper surface 9 of the surface material 2 and the folded surface 13 is set to an angle such that the end 14 of the folded surface 13 is located forward of the rear surface 15 of the reinforcing material 3.

  Further, as shown in FIG. 3A, the end portion 14 of the folded surface 13 and the upper end 5 of the reinforcing material 3 are provided so as to be in the vicinity of the pole or in contact with each other. Here, “in the vicinity of the pole” means that the end 14 of the folded surface 13 can abut the upper end 5 of the reinforcing member 3 when an external force due to the weight of the ceiling or the like acts downward on the upper surface 9 of the surface material 2. It means that it is the neighborhood where it becomes.

  As shown in FIGS. 1 and 2, the left and right side end portions of the front surface 8 of the surface material 2 (only the left side end portion is shown in FIG. 1 (a) and FIG. 2) It is bent in a substantially U-shape to form a side surface 18 and a side-folded surface 19.

  A longitudinal rail 4 is inserted from the side and fixed to the surface material 2 in the space surrounded by the front surface 8, the side surface 18 and the side folding surface 19 at the left and right side end portions of the surface material 2. And as shown in Drawing 1 (b) and Drawing 2 (a), upper surface 9 of surface material 2 is notched in the end part on either side, respectively, and notch 20 is formed.

  Furthermore, as shown in FIG. 2 (a), FIG. 3 and FIG. 4, a member such as a ceiling fixing member 23 (see FIG. 4) described later is inserted into the upper surface 9 and inserted into the wall panel 1 side. A unit 24 is provided. The member insertion portion 24 is a hole in the present embodiment, but may be a notch or may be a projection that protrudes a part of the upper surface 9 upward.

  The lower end portion of the surface material 2 is also formed in the same manner as the upper end portion. That is, the lower end portion of the front surface 8 of the surface material 2 is horizontally bent rearward (rear surface side) to form a lower surface 27 as shown in FIGS. 1 (a), 2 (b) and 3 . A gap 28 is provided between the lower surface 27 and the lower end 6 of the reinforcing member 3.

  The lower surface 27 has its tip end side folded upward and forward toward the central portion side in the thickness direction of the reinforcing member 3 to form a folded surface 29. The angle θ between the lower surface 27 and the folded surface 29 is formed to be an acute angle.

  The end 30 of the folded back surface 29 is formed to be located on the front side (surface side) of the rear surface (back surface) 15 of the reinforcing material 3. Further, as shown in FIG. 3A, the end portion 30 of the folded surface 29 and the lower end 6 of the reinforcing material 3 are provided in the vicinity of the pole or in contact with each other. Here, “in the vicinity of the pole” means the vicinity where the end 30 of the folded surface 27 abuts on the lower end 6 of the reinforcing member 3 when an external force is applied upward to the lower surface 27 of the surface material 2. It means that.

  The lower surface 27 of the surface material 2 is notched at each of the left and right end portions, as shown in FIG. 2B, and a notch 31 is formed. Furthermore, as shown in FIG. 2 (b) and FIG. 3, a member such as a floor fixing member (not shown) fixed to the floor 33 is inserted into the lower surface 27 and inserted into the wall panel 1 side. A unit 32 is provided. Moreover, in the case of the wall panel installed on a door, it is also possible to insert the member for fixing on a door into the member insertion part 32. FIG.

(Action)
In order to make the characteristics of the wall panel 1 having the above configuration clearer, its operation and the like will be described.

  The upper end portion of the surface material 2 is horizontally bent backward to form an upper surface 9 as shown in FIG. 3, and the upper surface 9 is further bent downward at an acute angle to form a folded surface 13 and folded back. The end 14 of the surface 13 is provided near or in contact with the pole of the upper end 5 of the reinforcing member 3.

  With such a configuration, as shown in FIG. 3B, even if the ceiling 36 etc. is placed on the upper surface 9 of the wall panel 1 and the weight of the ceiling 36 etc. acts on the upper surface 9, Since the end portion 14 does not protrude (step off) behind the rear edge 7 of the upper end 5 of the reinforcing member 3 and abuts on the upper end 5, the upper surface 9 is deformed downward as described in the first and second conventional examples. (Refer FIG.6 (c), (d)) is suppressed.

  Further, the upper surface 9 of the surface material 2 is folded back to form a folded surface 13, and a portion (referred to as a folded edge) 37 to be folded back functions as a so-called reinforcing rib and imparts rigidity to the upper surface 9. .

  In the configuration shown in FIG. 3, the upper end of the surface material 2, that is, the end 14 of the folded surface 13 is folded back toward the back surface of the front surface material 2 and is not exposed rearward. In the work of attaching the panel 1 or the like, it is difficult for the operator to touch the end portion 14 of the turnback surface 13 and the hand is prevented from being broken.

  And while the clearance gap 10 is formed between the upper surface 9 of the surface material 2 and the upper end 5 of the reinforcing material 3, since the member insertion part 24 is provided in the upper surface 9, as shown in FIG. In addition, the ceiling fixing member 23 can be fixed by inserting the engaging protrusion 40 into the gap 10 on the wall panel 1 side from the member inserting portion 24.

  In addition, as shown in FIG. 4, the ceiling fixing member 23 includes a main body portion 41, an overhang portion 42 projecting forward from the upper end of the main body portion 41, an engagement projection 40 projecting downward from the overhang portion 42, and an overhang And a hook-like engaging portion 43 extending upward from the portion 42. The engagement portion 43 engages with the engagement hole 46 formed in the ceiling 36 and positions the wall panel 1 on the ceiling 36.

  The action of the upper surface 9 of the wall panel 1 is the same as that of the lower surface 27 of the surface material 2. That is, the lower surface 27 of the wall panel 1 is placed on the floor 33 and installed as shown in FIG. 3B, but received from the floor 33 as a reaction force of the weight of the ceiling 36 and the wall panel 1 Even if the force acts on the lower surface 27 of the surface material 2, the end 30 of the folded surface 29 abuts on the lower end 6 of the reinforcing material 3, so that the lower surface 27 is suppressed from being bent upward.

  Further, the folded edge 47 in which the lower surface 27 of the surface material 2 is folded back to the folded surface 29 functions as a so-called reinforcing rib, and imparts rigidity to the lower surface 27. Furthermore, since the lower end of the surface material 2, that is, the end 30 of the folded surface 29 is not exposed rearward, it becomes difficult for the operator to touch the end 30 of the folded surface 29 in the attachment work of the wall panel 1, etc. Is prevented from being cut.

  And while the clearance 28 is formed between the lower surface 27 of the surface material 2 and the lower end 6 of the reinforcing material 3, and the member insertion part 32 is provided in the lower surface 27, although illustration is not carried out, The floor fixing member and the member for fixing on the door can be fixed by inserting the engagement protrusion thereof from the member insertion portion 32 into the gap 28 on the wall panel 1 side.

  By the way, conventionally, the wall panel 1 has been manufactured by contacting and bonding the reinforcing material 3 to the rear surface (rear surface) of the surface material 2, but in such bonding work, the positioning of the reinforcing material 3 with respect to the surface material 2 is When it was troublesome and it adhered in the incorrect position, the correction was very troublesome. However, in the wall panel 1 of the present invention, such a problem is solved.

  That is, when affixing the reinforcing material 3 to the surface material 2 with an adhesive, as shown in FIG. 3C, the reinforcing material 3 is in contact with the surface material 2 from the side. As described above, according to the wall panel 1 of the present invention, when the reinforcing material 3 is in contact with the surface material 2 from the side, the reinforcing material 3 is placed at an appropriate position in the central portion of the surface material 2. , Easy to position.

  The reason is that, as shown in FIG. 3 (c), the wall panel 1 is folded back because the upper surface 9 and the lower surface 27 are respectively folded downward and upward at acute angles to form folded surfaces 13 and 29. This is because the surfaces 13 and 29 serve as guides to guide and contact the reinforcing material 3 to the appropriate position of the surface material 2.

  As mentioned above, although the structure of the upper part of the wall panel 1 and the lower part, and an effect | action are symmetrical vertically and is substantially the same, in the present Example, both were each demonstrated. However, only one of the upper and lower portions may be configured as described above.

(Modification)
Modifications 1 to 3 of the wall panel 1 of the above embodiment will be described with reference to FIG. In the first to third modifications, since the configurations of the upper and lower portions of the wall panel are vertically symmetrical and substantially the same, the upper and lower portions will be described simultaneously in the following description. However, only one of the upper and lower portions may be configured as follows.

  The wall panel 51 of the modification 1 shown in FIG. 5A further folds the folded surfaces 13 and 29 of the surface material 2 of the above embodiment toward the front surface 8 of the wall panel 1 horizontally, and an upper horizontal end surface 52, The lower horizontal end face 53 is formed.

  With such a configuration, the upper horizontal end face 52 and the lower horizontal end face 53 of the surface material 2 can stably contact the upper end 5 and the lower end 6 of the reinforcing member 3, and the upper folded edge 56, Since the lower folding edge 57 is further formed, the function as a reinforcing rib is added and the rigidity is further enhanced.

  The wall panel 61 of the second modification shown in FIG. 5 (b) includes the upper horizontal end face 52 and the lower horizontal end face 53 as in the first modification, but the upper surface 9, the lower surface 27 and the upper fold of the surface material 2 are folded. The angle formed by the surface 62 and the lower turning surface 63 is an acute angle, but an angle close to a substantially right angle.

  With such a configuration, in addition to the same effects as those of the first modification, since the bending process for forming the upper turning surface 62 and the lower turning surface 63 uses a substantially right-angled mold, the mold cost There is an effect that it is reduced and processing becomes easy.

  The wall panel 71 of the third modification shown in FIG. 5C is bent at an obtuse angle backward and downward from the upper surface 9 and the lower surface 27 first to form a gently inclined upper surface 72 and a moderately inclined lower surface 74, and the end thereof It is configured to be bent at an acute angle toward the upper end 5 and the lower end 6 of the reinforcing member 3 forward, upward, and backward to form folded surfaces 13 and 29.

  According to the wall panel 71 of the third modification, in the wall panel 1 of the first embodiment, the upper bending edge 73 from the upper surface 9 and the lower surface 27 of the surface material 2 to the upper surface 72 and the lower surface 74 is lower. The function as a reinforcing rib by the bending edge 75 is added and the rigidity is further enhanced.

  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 said was described in the claim. It goes without saying that there are various embodiments within the scope of the matter.

  Since the wall panel according to the present invention is configured as described above, it can be applied as a wall used in various applications, such as for structural parts and partitions of various places of a building. The wall panel according to the present invention is also applicable as described above.
