壁材１の上下方向の接合部分に横方向に沿って溝部３を
形成させるのは、専ら建築物壁面の意匠性を高めるため
である。Since the lengths La and Lb of the step portions 2a and 2b provided at the upper and lower end portions of the outer wall material 1 are different, the length La and Lb of the step portions 2a and 2b are provided at the joining portion of the upper and lower outer wall materials 1. A groove portion 3 having a width (Lc) corresponding to the difference in Lb is formed in the lateral direction. Thus, the reason why the groove portion 3 is formed along the lateral direction at the joint portion in the vertical direction of the outer wall material 1 is to enhance the design of the building wall surface exclusively.
そして、横方向に隣接する外壁材１の間に目地４が垂

されてしまう。The joints 4 are formed vertically between the laterally adjacent outer wall materials 1, and the joint material is inserted between the joints 4 to waterproof the joints 4. If the conventional joint material having the same height is inserted into the joint 4, the joint material partially projects at the connection portion of the groove 3. With such a structure, the joint 4 of the connecting portion of the groove portion 3 is not sufficiently waterproofed, the waterproof property is deteriorated, and wind collides with the joint material protruding in the connecting portion of the groove portion 3. Abnormal noise is generated, and the appearance of the outer wall of the building is damaged by the protrusion of the joint material.
これらの不具合を防止しようとする目地材として、特
開平１−137041号公報に開示されているものが知られて
いる。As a joint material for preventing these problems, the joint material disclosed in JP-A-1-137041 is known.
