Description

  The present invention relates to a structure of a vertical joint portion formed by attaching end portions in the longitudinal direction of a dry-type wall material used for construction and construction. More specifically, the present invention relates to a vertical joint structure in which the boundary portion between the vertical joint portion and the wall surface is formed so as to be indistinguishable and the cosmetic cap is not dropped off.

  In general, a dry wall material with a sandwich structure with a metal plate as a surface material, a synthetic resin foam as a core material, and a sheet-like material as a back material, or a dry wall material made of an inorganic material, is used as a horizontal wall. When the body is formed, vertical joints are formed by the longitudinal matching of the dry wall material. The vertical joints are simply attached together, a caulking material is planted, an H-shaped joiner is used, There is a method of forming a vertical joint by fitting two members of a plate and a decorative cap. (For example, see Patent Documents 1 to 3).

  However, since the upper end of the decorative cap is inserted into the fitting portion of the dry wall material, there is a risk that it will be detached from the wall body depending on the fitting state of the dry wall material.

  In order to solve such drawbacks, in the present invention, in the vertical joint structure covering the joint part of the dry wall material, the vertical joint structure is composed of a lining plate and a decorative cap, and the lining plate is a long plate material. The decorative cap comprises a vertical flat decorative face part and an engaging part projecting in the longitudinal direction at the center of the back surface of the decorative face part, and a dry wall material is provided at the upper end of the decorative face part. The vertical joint structure which formed the upper part corresponding to the cross-sectional shape of this horizontal joint part is provided.

  According to the vertical joint structure according to the present invention, since the upper part formed in accordance with the cross-sectional shape of the horizontal joint part of the dry wall material is formed at the upper end of the decorative surface part of the decorative cap, (1) the upper part is the dry type wall material. It is not inserted into the engagement groove between them, and can be fixed to the wall substrate independently without being influenced by the engagement state of the dry wall material. (2) Since it is fixed independently to the wall base without being influenced by the engagement state of the dry wall material, there is no influence (interference) by the dry wall material, and the engagement between the siding board and the decorative cap is reliable, There is no risk of the cosmetic cap falling off after construction. There are features and effects.

  Hereinafter, typical examples of the vertical joint structure according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view showing a construction state of a vertical joint structure according to the present invention, FIG. 2 is a perspective view showing a construction state of the vertical joint structure, FIGS. 3A and 3B are cross-sectional views showing a vertical joint structure, FIG. 4 is a cross-sectional view showing an embodiment of a dry wall material D used for a vertical joint structure, FIG. 5 is a cross-sectional view showing a construction state of the dry wall material D, A is a joint for a vertical joint, and B is a joint. A board, C is a decorative cap, D is a dry wall material, M is a joint, T is a vertical joint, Y is a horizontal joint, α is a wall base, and β is a fixture.

  In more detail, the vertical joint structure is a thin metal plate material such as iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel plate, galbarium steel plate, enamel steel plate, clad steel plate, laminated steel plate (PVC steel plate, etc.), sandwich steel plate. (Damping steel plate, etc.), synthetic resin plate materials such as vinyl chloride resin, polycarbonate resin (including color plates coated with various colors of course) are formed into various shapes by roll molding, press molding, etc. It is a thing.
