DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint for a frame of a building opening to be installed in a joint groove which needs to ensure watertightness between a frame for a fitting and a wall covering material around the opening of the building. It is about materials.

[0002]

2. Description of the Related Art Conventionally, silicon has been used as a means for sealing a joint groove between an adjacent wall exterior material such as siding in a building and a frame for a fitting around an opening of an entrance or a window. By filling a sealing material such as rubber into the joint groove, the watertightness of the joint groove is enhanced.

[0003] However, especially in the joint groove between the wall exterior material and the edge frame for fittings, the rainwater flowing along the wall often reaches the ground through the portion, and also the sealing material is not directly exposed. Since the sealing material is often exposed to sunlight, the sealing material deteriorates with time and the sealing effect is reduced, and when an external force such as an earthquake is applied, the sealing material is often easily peeled from the joint groove. . In addition, during the construction, it is necessary to fill the sealing material after masking so that the sealing material does not adhere to the wall exterior material and the edge frame for fittings, etc. It is necessary to construct the surface of the sealing material as flat as possible so as not to damage it and to prevent air bubbles from entering the sealing material, but the edge frame for fittings often hinders the work. Is required. Furthermore, when the sealing material is filled in the joint groove, unevenness may occur, and the sealing effect cannot always be enhanced.
