As shown in FIG. 2, the siding board B has a horizontal plane nailing piece 1 and a waterproof projection 2 formed on the nailing piece 1.
A fitting portion composed of vertical pieces 4 projecting upward from approximately the center of the nail driving piece 1, a fitting groove 5 between the vertical pieces 4, and a plurality of stages of fitting pieces 6 projecting into the fitting groove 5. 3 and 3.

The material of the floor board B is an extruded product (plastic material) of a synthetic resin material, or a metal plate material, such as polyethylene, polypropylene, vinyl chloride resin,
Styrene resin, methacrylic resin, polyurethane, phenol resin, urea resin (urea resin), melamine resin,
One of fluororesin, silicon resin, fiber reinforced plastic, or only one nailing piece is made of metal. In addition, vinyl chloride extruded products
Good in terms of performance.

The nail driving piece 1 is a portion for fixing the floor board B on the frame α via a fixing tool β such as a nail. The fitting portion 3 is for accommodating a metal decorative cap C, which will be described later, and for preventing the fitting cap 3 from coming off from the fitting groove 5.

The vertical piece 4 functions to form the fitting groove 5, a contact surface (guide surface) of the wall material E, a fixing surface of the wall material E, a planting surface of the caulking material, and a waterproof surface.

The fitting pieces 6 formed in a plurality of steps are for locking the engaging claws 12 of the metallic decorative cap C, which will be described later, so as not to separate from the fitting groove 5.
The engagement depth (allowable wall material thickness) can be adjusted by forming a plurality of steps.

The metal makeup cap C (hereinafter, simply referred to as a makeup cap) is shown in FIGS. 3 (a), 3 (b) and 4 (FIG. 3).
As shown in FIG. 5 (a sectional view taken along the line EE of FIG. 3A), FIG. 5 (an end view taken along the line ROLL of FIG. 3A), and FIG. 6 (an end view taken along the line WH of FIG. 3A). For example, the insertion piece 7 having a length corresponding to the width of the wall material E shown in FIG. 7, a rising piece 8 in which one end edge of the insertion piece 7 is bent inward at a substantially right angle, and a rising piece 8 A bottom surface 9 whose lower end is bent outward at a substantially right angle, an engagement piece 11 whose tip is bent inward at a substantially right angle, and an engagement claw 12 which is formed by projecting from the engagement piece 11. The engaging portion 10, the engaging claw 13 protrudingly formed in the vicinity of the other end edge of the insertion piece 7, the notch 14 for forming the engaging claw 13 in an intermittent manner, and the upper end of the bottom surface 9. The waterproof piece 9a is formed, and the insertion piece 7 and the rising piece 8 have the same shape as the cross-sectional shape of the wall material E, and are a pair of short left and right, . 3 (a) left for the longitudinal joints F, FIG. 3 (b) is for the right side with respect to the longitudinal joint F.

The insert piece 7 has a male-female connecting structure at the left and right ends as shown in FIG. 7, and has a front surface material E ₁ , a back surface material E ₂ , and a core material E _3.
The boundary between the surface material E ₁ and the core material E ₃ of the wall material E made of
As shown in FIG. 3, the locking claws 13 are fixed to the surface of the wall material E, and the surface of the wall material E is covered with the rising pieces 8 so that the core material E ₃ of the wall material E is exposed to the outside. This is useful for preventing fluttering, improving aesthetics and preventing fluttering at the edge of the wood mouth.

The insertion piece 7 and the rising piece 8 have the same shape and size as the cross-sectional shape of the wall material E as shown in FIG. 7. By forming the shape and size to be the same, the joints on the side of the wall material E are formed. Since the line is not divided, the vertical joint F has a significantly improved design.

The bottom surface 9 is for forming joints on the vertical joints F, and a flat surface is formed by the left and right decorative caps C, and the waterproof piece 9a is covered with the lower end portion of the bottom surface 9 to form the joint portion F. It is formed and functions as a joint forming surface and a waterproof surface.

The waterproof piece 9a is bent so that the upper end of the bottom surface 9 is bent downward by about the plate thickness of the decorative cap C and is covered by the lower end of the bottom surface 9 at the time of connection to smooth the vertical connection of the decorative cap C, and This is for improving the waterproofness of the connecting portion.

When the engaging piece 11 is inserted into the fitting groove 5 of the mat board B, the engaging portion 10 combines the engaging claw 12 with the fitting piece 6 to exert an engaging force. The engaging claw 12
Is formed at a pitch P by drawing (louvering) as shown in the drawing, or although not shown, the tip of the engaging piece 11 is partially bent and formed with an interval, or the length of the cosmetic cap C is increased. It is also possible to form continuously in the direction.

The locking claws 13 are the surface material E ₁ of the wall material E and the core material E.
_It is inserted at the boundary with _3, and is for fixing the decorative cap C to the ostium of the wall material E. The vertices of the wall material E are covered with the rising pieces 8, and the core material E ₃ of the wall material E is It is useful for preventing exposure to the outside, improving aesthetics, and preventing fluttering at the end of the wood mouth.

Here, the dimensional relationship of each part will be briefly described. Therefore, the width of the vertical joint F between the wall materials E is W ₁ , the width between the vertical pieces 4 in the floor plank B is W ₂ , the width of the bottom surface 9 is W ₃ ,
Cosmetic cap height h ₁ of the C, and the thickness of the wall material E and h _2, the relationship of _{W 1 = W 2, W 1} = 2W 3, h 1> h 2.

Next, the construction method will be briefly described with reference to FIGS. First of all, Joiner A on a wall base on which a waterproof sheet D is laid on a frame α composed of studs, main columns and furring strips.
The nail striking piece 1 of the sheet B is struck by the fixture β in the portion where is used to fix the sheet B vertically. Next, as shown in FIG. 8, a decorative cap C is inserted and fixed at the end of the opening of the wall material E, and the wall material E is fixed.
Are sequentially brought into contact with the left and right sides of the vertical piece 4 of the sheet B, and the engaging portion 10 of the decorative cap C is fitted to the fitting groove 5 of the sheet B.
To engage the engaging claw 12 with the fitting piece 6, and fix the wall material E on the wall base material through the fixing tool β as shown in FIG. 9 to fix the left and right wall materials E from the base to the girder. To form vertical joints F as shown. Of course, the caulking material G is formed on the formed vertical joint F as shown by the dotted line,
Further, the waterproof property can be improved.

What has been described above is only one embodiment of the vertical joint structure according to the present invention, and FIGS. 10 (a) to 10 (f) and FIG.
It can be formed using the makeup cap C as shown in (a) to (f), and is shown in FIGS.
11A to 11F are makeup caps C for the left side of the vertical joint F, and FIGS.

FIG. 12 shows another embodiment of the vertical joint structure according to the present invention. The surface material E _{1 of the} wall material E is shown in FIG.
This is a vertical joint structure in which the rising piece 8 of the makeup cap C is sandwiched by the end portion E ₄ of. When formed in this way,
The cut end of the surface material E ₁ of the wall material E is not exposed to the outside,
The vertical joint structure has improved design.

[0023]

As described above, according to the vertical joint structure of the present invention, since the metallic decorative cap is fitted and integrated through the fitting portion of the synthetic resin sheet, the metallic joint cap is made of metal. There is no heat bridge between the decorative cap and the siding board, no condensation occurs inside the skeleton on the back surface of the siding board, and corrosion of the skeleton can be prevented. Since the makeup cap has the same cross-sectional shape as that of the dry wall material, the horizontal joint of the dry wall material is not divided by the makeup cap, and the vertical joint structure has significantly improved design. Since the vertical joints are covered with caulking material, it is surely waterproof. There are characteristics and effects.
