Abstract

PURPOSE:To promote work efficiency and beauty efficiency in the case a butt joint part such as jointless glasses or clear panels, etc., are sealed with sealant by laminating a soft foamable material having width narrower than a hard foamable material on an adhesive layer on one side of the hard foamable material, and providing a stripping agent layer on the soft foamable material. CONSTITUTION:An adhesive layer 2 is provided on one side of a hard foamable material, a soft foamable material 3 having width narrower than the hard foamable material is laminated thereon, and a stripping agent layer 4 is provided on the soft foamable material to form a backup material A. Glasses 7 and 7 are so arranged that they are butted on each other at a specific interval, masking tapes 9 and 9 are stuck on one side of the ends of the glasses 7 and 7, and the backup material A is stuck on them. Then, after a joint part is filled with non-sag sealant 8, the surface of the sealant 8 is levelled with a leveller, and it is left for a specific period of time. After that, the tapes 9 are stripped from the plate glasses 7, and the backup material A is stripped from the solidified sealant 8.

In recent years, due to changes in architectural styles, butt joints such as glass or transparent panels having no joint bottom are often sealed with a sealing material. In such a sealing operation, a conventional backup material cannot be used. For example, a method of arranging a stiffener glass or a rib glass on the back surface of a butt joint portion such as glass or a transparent panel (see Japanese Utility Model Publication No. 54-6257 and Japanese Utility Model Publication No. 54-6257).

However, according to the former method, the stiffener glass or the rib glass must be arranged on the back surface of the butt joint portion of the glass or the transparent panel, and the space and the scenery are varied. There was a problem of being restricted. Further, in the latter method, since the joint plate is present in the butt joint portion of the glass or the transparent panel, there is a problem that the beauty of the butt joint portion of the glass or the transparent panel is impaired. For this reason, in order to seal butt joints such as glass or transparent panels without joint bottoms with a sealing material, it is necessary to simultaneously fill the sealing material from the front and back of the joint and make the front and back surfaces of the sealing material even with a spatula. Therefore, there is a problem that the workability of the sealing work and the finish of the sealing material are poor.
