Description

The present invention relates to a structure of vertical joints formed by joining the longitudinal ends of drywall materials used in buildings and structures. More specifically, the present invention relates to a structure in which rainwater is prevented from entering from a connecting portion of the drywall material, which is a cross-joint portion of the drywall material.

Generally, a drywall material with a sandwich structure using a metal plate as a surface material, a synthetic resin foam as a core material, and a sheet-like material as a backing material, or a drywall material made of an inorganic material is used to form a horizontal wall. When the body is formed, vertical joints are formed by abutting the drywall material in the longitudinal direction, and the vertical joints are simply sewn together, caulking material is planted, H-shaped joiners are used, and floor joints are used. There is a method of forming vertical joints by fitting two members, a board and a decorative cap. (See, for example, Patent Documents 1 and 2).
