DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in which longitudinal dry wall materials (hereinafter simply referred to as "wall materials") used in a building or a building are joined in a longitudinal direction, that is, a vertical joint structure.

[0002]

2. Description of the Related Art Generally, a wall material formed of 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 wall material made of an inorganic material is used. When the wall is constructed in a stretched state, vertical joints are formed at the butting portions in the longitudinal direction of the wall material. The vertical joints are simply butt-butted or a method of planting a caulking material at the joint is used, but there are problems in weather resistance, workability, and aesthetics.

As a method of solving such a problem, a vertical joint structure in which a vertical joint portion is covered by using two members, a decorative cap and a floor plate, has been widely applied in recent years. Although the invention relates to a vertical joint structure is already many applications, as the structure is similar to the present invention, Kokoku 7-99046 Patent Publication is disclosed.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram of claim 1 of the present invention, and FIG.
(1) is a decorative cap used in claim 1 of the present invention, FIG.
(2) is an explanatory view of the stitch plate.

[0008] As shown in FIG.
Is composed of a decorative face plate 2 and a fitting portion 9, and the fitting portion 9 is composed of two outer guide pieces 10 and an inner guide piece 11 protruding. Two outer guide pieces 10 protrude upward from substantially the center of the decorative face plate 2, and one inner guide piece 11 protrudes from between them. Therefore, the fitting portion 9 has a substantially inverted W-shaped cross section in which two substantially inverted V-shaped fitting grooves 12 are combined. Fitting claws 13 are formed on both side surfaces of the inner guide piece 11.

As shown in FIG. 2 (2), a horizontal plate 8 of the tiling plate 7 and an engaging portion 3 are provided. Each of the engaging portions 3 has two pairs of a rising piece 4, a restraining piece 5, and a fitting. It consists of a piece 6. Startup piece 4 two protrudes from the back surface substantially center of the horizontal plate 8, further a restraining piece 5 bends the beyond each of the width than the substantially inverted V-shaped decorative cap is wide substantially inverted V-shaped fitting piece 6 is formed. The tip of the fitting piece 6 is further bent to provide an engagement projection 17.

FIG. 1 illustrates a vertical joint structure according to claim 1 of the present invention using two members, a decorative cap 1 and a floor plate 7. The horizontal plate 8 of the floor plate 7 is fixed to the wall foundation 14 with nails 15, the wall material 16 is disposed on the wall foundation 14 on both sides of the two rising pieces 4, and the decorative cap 1 is placed on the floor board. Insert into 7. A substantially inverted V-shape of the width of the mat first plate 7 of the decorative cap 1 substantially inverted
Since the width is wider than the V-shape , the engaging portion 3 is elastically deformed inward by the elasticity of the compression direction received from the fitting portion 9 and is in close contact with the fitting portion 9 as described above.

FIG . 3 is a schematic diagram of the first embodiment of the present invention.
FIG. 4 is an explanatory view of a process in which a cosmetic cap 1 is detached from a floor plate 7.
3 (1) is in the inserted state, FIG. 3 (2) is in the middle, FIG.
(3) shows the state of the disconnection completion. You can see from Figure 3 (2)
As described above, according to the first aspect of the present invention, the decorative cap 1 is detached.
Even in the state of being hooked, the engaging portion 3 is formed by the outer guide piece 10 and the inner guide piece.
Elastic deformation inward due to the elastic force in the compression direction received from 11
It has the advantage that it does not come off easily because it adheres well
You. FIG. 4 is an explanatory view of the second embodiment of the present invention.
(1) Cosmetic cap used in the invention of claim 2 of the present invention, FIG. 5 (2) is an explanatory view of the insole th plate. Claim 2
Invention is characterized in that is not provided against engaging projections to the invention of claim 1, others are no different. Claim
In the case of the invention of item 2, the distal end surface of the fitting piece 6 serves as an engagement projection. The invention of claim 1 is suitable when the workability when the decorative cap 1 is intentionally removed from the floor plate 7 is considered, but the invention of claim 2 is suitable when the decorative cap 1 is not intentionally removed.

FIG. 6 is an explanatory view of the third aspect of the present invention,
7 (1) Cosmetic cap used in the invention of claim 3 of the present invention, FIG. 7 (2) is an explanatory view of the insole th plate. Claim 1
The difference from the invention is that the arrangement of the fitting piece 6 and the restraining piece 5 is reversed, and the fitting claw 13 is not the inner guide piece 11 but the outer guide piece 1.
A point having zero, but functionally no different from the first aspect of the present invention.

[0013]

According to the present invention, a vertical joint according to claims 1 to 3 is provided.
Due to the structure, even if the decorative cap receives a large external force, the engaging portion of the decorative cap is
Pressure applied from the outside to the inside by the guide piece and the inner guide piece
It adheres while elastically deforming inward due to elasticity in the shrinking direction
Engaged in, which has the property of easily disengaged difficult decorative cap off compared with the structure of the conventional vertical joints, also repeatedly and in cosmetic cap detachable, flooded in cold climates, even if freezing expansion Elasticity due to plastic deformation of the piece
And the makeup cap may come off easily.
It has such effects as
