  According to the insertion piece disclosed in Patent Document 1, it is possible to prevent damage caused by the base material 8 and the pillar 11 hitting by an earthquake, and positioning at the time of mounting the exterior panel 15 by the wide portion 9 can also be performed. But there is still room for improvement.

  The present invention improves the insertion piece disclosed in Patent Document 1 so that it can be easily inserted into the joint between the base material and the column and can be smoothly performed, and also supports variations in joint width. It is an object of the present invention to provide a joint spacer that is easy to do.

In the invention according to claim 1, after the base material provided with the outer wall panel is formed with a joint between the pillars and attached, the spacer is positioned with respect to the base material so that the front side is flush with the nail, The above-mentioned spacer having an outer wall structure in which the outer wall panel is attached to the spacer from the front side by attaching to the end surface of the base material by fixing means such as screws and adhesive, and is made of resin or rubber. A spacer main body fixed to the side end surface by the fixing means, and an insertion portion that is integrated with the spacer main body and inserted into the joint, and a lip that elastically contacts the column on one side of the insertion portion. Each lip is formed so that the protruding amount gradually increases toward the distal end of the insertion portion, and the other side of the insertion portion forms a flat surface flush with the spacer body and is joined to the base material side end surface. Features
The invention according to claim 2 is characterized in that, in the invention according to claim 1, the insertion portion is provided with a notch for easily cutting the insertion portion between the root and the lip.

  The invention according to claim 3 is the invention according to claim 1 or 2, wherein the fastening means is a nail, and the surface on which the nail on one side of the spacer body is driven is uneven to make the applied nail tip difficult to slip. It is characterized by being formed.

  According to the first aspect of the invention, the spacer can be held by inserting the insertion portion into the joint between the base material and the column, and the spacer body is positioned so as to be flush with the base material and stopped. Compared with the case where the insertion part with lip formed on both sides is inserted into the joint with the same joint width and the case where the insertion part with lip formed on one side is inserted, the lip on both sides In the former insertion part provided, the lip on each side is shortened and rigidity is increased, whereas in the latter insertion part provided with the lip on one side, the lip is made relatively long and rigid. Therefore, it is easy to insert the lip into the joint while bending the lip, and the lip is easy to bend. Is elastic In order to avoid direct contact between the base material and the column, damage due to contact can be avoided, and when inserting into the joint, the insertion portion should be stiff so that the insertion portion will not bend for smooth insertion. However, in an insertion part provided with a lip on one side, even if the lip is made of the same material as that of the insertion part, it can be made long, so even if the rigidity of the insertion part is increased, the flexibility of the lip may be impaired. There is an effect that it can be smoothly inserted along the side end surface of the base material because the one side of the insertion portion is a flat surface.

  According to the invention which concerns on Claim 2, the lip according to joint width can be pushed in and inserted in a joint. In other words, when the joint width is wide, the insertion part is inserted into the joint as it is, and when the joint width is narrow, the insertion part is cut into pieces to remove a lip having a large protruding amount, and a lip having a protruding amount that matches the joint width is pushed in and inserted. To do. When the joint width is small or almost absent, the base of the insertion portion is cut off to remove the entire insertion portion, and the insertion into the joint is not performed.

  In the invention according to claim 3, when the nail is applied to the spacer main body and driven, the nail tip is difficult to slip, so that the nail driving becomes easy.

Hereinafter, joint spacers according to embodiments of the present invention will be described with reference to the drawings. In the figure, the same structural parts as those shown in FIG.
