When the outer wall of a building is composed of a plurality of panels, a groove-shaped joint is formed between the end faces of each panel. Conventionally, a joint member disclosed in Patent Document 1 is known as a joint member disposed on such joint. The joint member includes a joint member body formed in an elongated shape by an elastic material and a holding member formed in an elongated shape by a material having rigidity.
[0003]
However, in this joint member, a part of the holding member is arranged between the panel and the base material, and this part is fixed with a fixing member having a head such as a screw, and the joint member is arranged on the joint. In order to sandwich the holding member between the panel and the base material, the holding member must be installed before the panel is attached to the building, and there is a problem that the working order is limited. In order to solve this problem, after installing the panel on the building, for example, a substantially U-shaped holding member corresponding to the joint shape is fixed by a fixing member, and the joint member main body is fitted and fixed to the holding member. It is thought that it should be done. However, in this case, the head of the fixing member protrudes toward the joint member main body at the bottom wall portion of the holding member and interferes with the joint member main body. For this reason, the joint member main body is partially convex at the position where the head of the fixing member is located, and the joint member main body is uneven in the depth direction of the joint, resulting in a decrease in appearance.
[0004]
For this reason, it is also conceivable to employ the joint member described in Patent Document 2. The joint member is divided into an appearance member that is visible from the outside when the joint member main body is disposed, and a plurality of receiving members that are located closer to the base material of the building than the appearance member. The appearance member is formed in a long shape and has a long fitting piece. Further, the receiving member is formed shorter than the appearance member in the longitudinal direction, and has a fitting projection that can be fitted to the fitting piece of the appearance member in a state that it can slide in the longitudinal direction of the appearance member.
[0005]
In this joint member, the receiving member is fitted to the external member in a state in which the receiving member can slide in the longitudinal direction of the external member by fitting the fitting piece of the external member and the fitting protrusion of the receiving member. Therefore, in this joint member, the receiving member can be arranged avoiding the position where the head of the fixing member is located, and the appearance member can be prevented from being uneven, and the decorative effect can be improved.
