  Embodiments of the present invention will be described below.

  FIG. 1 shows an example of a joint structure of an outer wall according to the present invention. In this example, a plurality of pillars 12 (other pillars 12 are not shown in FIG. 1) are set up separately, and a base material 13 formed of plywood or the like is attached to the outdoor side of each pillar 12, and then this base A moisture permeable waterproof sheet 14 is stretched on the surface of the material 13. Further, a receiving plate (wooden rim) 15 having a thickness of about 12 mm is attached to the surface on the outdoor side of each column 12 with a screw or the like via a base material 13 and a moisture permeable waterproof sheet 14.

  A joining member 3 made of a metal such as aluminum is attached to the receiving plate 15 with fastening screws 16. Here, as shown in FIGS. 2B, 2 </ b> C, and 3, the joining member 3 has a pair of vertical pieces 2 and 2 spaced apart from each other at a predetermined interval at a substantially central portion of one surface of the long fixed piece 1. It is formed so as to be parallel to the longitudinal direction of the fixed piece 1. Further, the vertical pieces 2 and 2 of the joining member 3 are suspended on the fixed piece 1 so as to be higher than the thickness (about 16 mm) of the outer wall material 4. Further, on the surface of the fixed piece 1 on which the vertical pieces 2 and 2 are provided, a plurality of grooves 17 having a depth of about 0.5 mm are provided at equal intervals from the vertical pieces 2 toward the side edges of the fixed piece 1, for example, 5 mm intervals. Is formed. When the joining member 3 is attached to the backing plate 15, the fastening screw 16 can be prevented from slipping on the fixed piece 1 by inserting the tip of the fastening screw 16 into the groove 17. The mounting work can be performed smoothly.

  Next, as shown in FIG. 1, a fastener 18 for attaching the outer wall material 4 is fixed to the base material 13 with the fixing tool 19 via the moisture-permeable waterproof sheet 14. Here, as the fastener 18, for example, as shown in FIG. 4A, one formed by providing an upward holding piece 45 and a downward holding piece 46 on one surface of the fixed piece 21 can be used. And when attaching the outer wall material 4 up and down using this fastener 18, first, as shown in FIG. 4 (b), a downward holding piece of the fastener 18 is provided on a locking projection 62 provided at the upper end of the outer wall member 4. The fastener 18 is passed through the fixing hole 41 provided in the fixed piece 21 while the stopper 46 is locked, and the fastener 19 is screwed or struck to the base material 13, thereby fixing the fastener 18 to the moisture permeable waterproof sheet 14. It fixes to the base material 13 via. After the lower outer wall material 4 is installed in this manner, the upward holding piece 45 of the fastener 18 is locked in the groove portion 61 provided at the lower end portion of the other outer wall material 4. By repeating as necessary, the outer wall material 4 can be attached up and down.

  A plurality of outer wall members 4 and 4 are installed with a gap between them. At this time, the outer wall member 4 is aligned with the edge of the groove 17 formed in the fixed piece 1 of the joining member 3, The material 4 is attached to the fastener 18. As described above, since the groove 17 is formed in the fixed piece 1, the outer wall materials 4 and 4 installed on both sides of the joining member 3 can be easily aligned. In addition, since a plurality of grooves 17 are formed in the fixed piece 1, the gap between the adjacent outer wall materials 4 and 4 can be arbitrarily changed.

  Between each outer wall material 4 installed on both sides of the joining member 3 and the vertical piece 2 of the joining member 3, gaps of about 10 mm are formed at equal intervals. First, foamed polypropylene and foamed polyethylene are formed in this gap. Alternatively, the back-up material 20 formed of various resins or the like is inserted into the back and packed, and then a primer is applied to the inner surface of the gap and then the sealing material 5 is filled. As described above, by using the backup material 20 that does not adhere to the sealing material 5, it is possible to prevent three-sided adhesion, improve water tightness, and prevent water and the like from entering the indoor from the outside.

  Here, since the vertical piece 2 of the joining member 3 is suspended on the fixed piece 1 so as to be higher than the thickness of the outer wall material 4, the tool used for the primer application work and the sealing material 5 filling work. May be caught in the corner of the tip of the vertical piece 2, so that these operations may not be performed smoothly. Therefore, in such a case, the inclined surface 11 may be formed on the outer wall material 4 side of the tip of each vertical piece 2 as shown in FIG. The inclined surface 11 prevents various tools from being caught, the primer can be easily applied to the gap between the vertical piece 2 and the outer wall material 4, and the sealing material 5 can be easily filled. It is possible to improve the property.

  The joint structure of the outer wall is formed as described above, and the fixing piece 1 of the joining member 3 is arranged on the rear surface side (indoor side) of the outer wall materials 4 and 4 as shown in FIG. The pair of vertical pieces 2, 3 protrude from the front surfaces of the outer wall members 4, 4 through a gap between the adjacent outer wall members 4, 4. The pair of vertical pieces 2 and 2 protruding in this way can be seen from the outside, and these vertical pieces 2 and 2 can add an appearance accent to the joint portion, compared with the joint structure of the conventional outer wall. Thus, the design can be improved.

  By the way, normally, a plurality of outer wall materials 4 are used and installed vertically and horizontally, so that the length of the joining member 3 may be insufficient. In this case, as shown in FIG. 3, the plurality of joining members 3 and 3 are arranged side by side so that the vertical pieces 2 and 2 are continuous. At this time, the joint between the adjacent joining members 3 and 3 is conspicuous. There is a risk that. Therefore, in such a case, a connector 9 made of a metal such as aluminum as shown in FIGS. 2A and 3B may be used. In FIG. 3, the components other than the joining member 3 and the connector 9 are not shown. The connector 9 is formed by extending a pair of side plate pieces 7 and 7 from the both side edges of the bottom plate piece 6 substantially vertically to the same side and providing an engaging portion 8 at the tip of each side plate piece 7. Here, the width of the bottom plate piece 6 of the connector 9 is substantially equal to the distance between the pair of vertical pieces 2, 2 of the joining member 3, and the height of the side plate piece 7 of the connector 9 is the vertical piece 2 of the joining member 3. Is approximately equal to the height of Each engaging portion 8 of the connector 9 is formed in a claw shape by bending the tip end portion of each side plate piece 7 to the side opposite to the other side plate piece 7. On the other hand, an engagement protrusion 10 that engages with an engagement portion 8 of each side plate piece 7 of the connector 9 is provided at the tip of each vertical piece 2 of the joining member 3. Each engagement protrusion 10 of this joining member 3 is formed by bulging the tip of each vertical piece 2 to the opposite side of the other vertical piece 2.
