It is widely known that the outer panel is fixed to the outer edge by screwing the outer panel to the rear edge of the outer wall panel with screws. [0003] In such a mounting structure of the outer wall panel, as a means for fixing the connected outer wall panel to the backside rim, the outer side of each joint portion of the outer wall panel is used. In order to insert the screw into the backside rim from the outside, it is difficult to clearly grasp the height position of the backside rim located on the back side from the outside of the outer wall panel, and it is difficult to perform screwing work, and the outer wall panel To prevent rainwater from entering from the holes after the screws are screwed from the outside of the screw, it is necessary to take care that the surface of the holes is closed with a washer through the seal washer to the screw. There was a problem that it was troublesome and could not be performed efficiently. According to the present invention, in order to solve the above-mentioned problems in the conventional outer wall panel mounting structure, the outer wall panels are connected to each other via joints provided on both side edges. It is an object of the present invention to provide an outer wall panel mounting structure in which a screw portion can be easily screwed to a joint portion of an engaged outer wall panel from a back side rim in a state, and a screwed portion is not exposed outside the outer wall panel. Things. According to the present invention, as one specific means therefor, one side edge along the longitudinal direction of the outer wall panel has an inward joint bent from the side to the inside of the back side of the panel, and the other side edge has It has an outward joint bent from the side to the outside of the back side of the panel, and connects a plurality of adjacent panels to each other by engaging the outward joint and the inward joint with each other, on the back side of the connected panel A body edge having a plurality of stop holes opened at predetermined intervals based on the distance between the engaged inner and outer joint portions is disposed, and the body edge is located at the inner and outer joint portions engaged with each other. The outer wall panel and the body edge are screwed through a hole in the body edge. [0006] The body edge disposed on the back side of the outer wall panel is made of a Z-shaped section steel in which both side edges along the length direction are bent in opposite directions, and a plurality of stop holes are provided on one side edge. It is preferable that the structure is established at predetermined intervals. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A mounting structure of an outer wall panel according to the present invention will be described with reference to an embodiment shown in the drawings. The mounting structure of the outer wall panel is, as shown in FIG.
And a body edge 5 arranged on the back side of the panel 1. The outer wall panel 1 has a reinforcing groove 2 recessed in the center in the length direction toward the back side. have. The outer wall panel 1 has an inward joint 3 bent at one side edge 1a along the longitudinal direction of the outer wall panel from the side surface toward the inside of the back surface of the panel 1, and the other side edge. 1b has an outward joint 4 bent from the side surface toward the outside of the rear surface of the panel 1. As shown in FIG. 2, the inward joint 3 provided on one side edge 1a of the panel 1 has a side 3a bent at a right angle in a lateral direction and a side 3a. The back side 3b is formed by bending the back side 3b at a right angle toward the inside and the locking side 3c having the front end of the back side 3b bent toward the back side of the panel. Further, the outward joint 4 provided on the other side edge 1b of the panel 1 has a side 4a bent at a right angle in the side direction, and a back side formed by bending the side 4a at a right angle toward the outside of the back surface of the panel. A side 4b and a locking side 4c formed by folding the front end of the back side 4b toward the back side of the panel are formed. In addition, the side 4a and the back 4
b is slightly longer than the side 3a and the back side b of the inward joint 3 provided on one side edge 1a of the panel 1 so that the inward joint 3 can be fitted into the outward joint 4. It is preferable to keep it. Therefore, as shown in FIG. 1, the inward joint 3 of another outer wall panel 1 adjacent to the surface of the outward joint 4 of the outer wall panel 1 can be fitted. By fitting the inward joint 3 of another outer wall panel 1 into the outward joint 4 of the panel, a plurality of outer wall panels 1
Are connected to each other in series via the inner and outer joints 3 and 4. On the other hand, as shown in FIG. 3, the body edge 5 arranged on the back side of the outer wall panel has a Z-shaped cross section formed by bending both side edges 5a and 5b along the length direction in opposite directions. A plurality of stop holes 6 are formed at one side edge 5a at predetermined intervals. The distance h between the stop holes 6 formed in the one side edge 5a is determined by the center A of the back side 3b of the inward joint 3 of the outer wall panel 1 and the back side 4b of the outward joint 4. Is set to be equal to the length H connecting between the center portion B and the center portion B. As shown in FIG. 1, the outer wall panel mounting structure of the present invention having the above-described structure firstly arranges a body edge 5 horizontally above a portion constituting a wall surface via a pillar. The outer wall panel 1 is set up on the front surface of the body wall 5, and the inward joint 3 of the outer wall panel 1 is fixed to the body edge 5 through a tapping screw 7 from a stopper hole 6 a formed at one end of the body wall 5. Next, as described above, the inward joint 3 of another outer wall panel 1 is fitted into the surface of the outward joint 4 of the outer wall panel 1, and the adjacent panels 1, 1 are connected to each other. At that time, since the stop hole 6b is opened in the body edge 5 at the same interval as the length between the center of the inward joint 3 and the outward joint 4 of the panel 1, the inside and outside engaged with each other. The center of both joints 3 and 4 coincides with the position of the stop hole 6b, and the inner and outer joints 3 and 4 are fixed to the body edge 5 through the tapping screw 7 from the stop hole 6b.
Hereinafter, the outer wall panel 1 is screwed to the body edge 5 while being connected by a similar procedure. When the outer wall panel 1 is combined at a corner of a building, for example, as shown in FIG.
