Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to dry wall materials (hereinafter referred to as fi'
This relates to the structure of the longitudinal joints, that is, the longitudinal joints of the wall materials (L is referred to as wall material).

[Conventional technology]

In general, walls are formed in a sand-inch structure with a metal plate as the surface material, synthetic resin foam as the core material, and a sheet material as the back material, or wall materials made of inorganic materials are used to form horizontal walls. When the wall is formed, joints, so-called vertical joints, are formed by butting the wall materials in the longitudinal direction, and there is a method of simply butting the vertical joints and planting caulking material in the joints. However, caulking materials have the disadvantage that they cannot maintain their waterproof properties and design over a long period of time due to changes in weather resistance and deterioration by ultraviolet rays. However, wall materials using synthetic resin foam as the core material tended to deform the metal plates serving as the surface material at the ends in the longitudinal direction, making it difficult to install caulking material. Furthermore, since wall materials made of inorganic materials are brittle, the edges of the wall materials tend to chip, resulting in poor aesthetic appearance at vertical joints. For this reason, there is a method of using a joiner with an H-shaped cross section for vertical joints. However, with this method, it is necessary to insert the wall material into the U-shaped parts formed on both sides of the joiner, which may cause deformation or damage to the wall material and deformation of the joiner itself, which may affect the aesthetics or waterproofness. It had the disadvantage of lacking in. Additionally, in order to improve waterproofness, caulking material or the like is sometimes planted in the joiner, but long-term waterproofness cannot be expected and there is no certainty.

[Object of the Invention] In order to eliminate such drawbacks, the present invention includes a slat board formed from a horizontal nail driving piece and a fitting part into a round cross section, and a cross section T formed from a decorative surface part and an engaging part. It consists of two parts, a decorative cap formed in a letter shape, and the vertical joint joiner is used to form a cross section into an 11-shape by combining the decorative cap and the siding board, and after fixing the siding board, the wall material is installed. After the wall material is installed, the engaging part of the decorative cap is fitted to the fitting part of the siding board to facilitate construction, and the waterproof projections formed on the nailing pieces of the siding board are This invention relates to a vertical joint structure for forming a bed that is made of soft plastic and has significantly improved waterproofness, as well as improved workability and design.

[Structure of the invention]

A typical vertical joint structure according to the present invention will be explained in detail below using the drawings. Fig. 1 is a sectional view showing the above-mentioned vertical joint part, where A is a joiner for vertical joints (hereinafter simply referred to as a joiner), B and C are a decorative cap and siding board that make up joiner A, and D is a wall material. be. To explain further, Joiner A is a long metal plate (color steel plate, aluminum plate,
A decorative cap B and plastic are extruded by roll forming, press forming, extrusion molding, injection molding, etc. of a PVC steel plate, stainless steel plate, sandwich steel plate, clad steel plate, etc.) or a synthetic resin plate as shown in Fig. 2(a). It consists of two members, a paving board C formed by molding, injection molding, etc. as shown in FIG. 2(b). More specifically, as shown in Figure 2 (al), the cosmetic camp B has a long shape with a length of, for example, 909 to 7272+n, or a length corresponding to the width of the wall material, and has a surface on the decorative surface and an engaging portion. This decorative surface portion 1 has a substantially T-shaped cross section.
consists of a horizontal horizontal surface 2 and inclined decorative surfaces 3.4 provided on both sides of the horizontal surface 2, and the horizontal surface 2 covers the ends of the wall material at the vertical joints of the wall as shown in Figure 1. This is a part that improves the design, and the inclined decorative surface 3.4 improves waterproofness by closely adhering to the wall material in line contact.

The engaging portion l consists of an engaging piece 6 projecting downward from approximately the center on the decorative surface portion, and an engaging protrusion 7 projecting outward at the tip or midway of the engaging piece 6, and will be described later. When the engaging piece 6 is fitted into the fitting groove 12 of the board C, the engaging protrusion 7 is combined with the fitting pawl 13 to strengthen the engagement force. The engaging protrusions 7 may be formed by drawing as shown in the figure, or may be formed by partially bending the tip of the engaging piece 6 (not shown) with intervals, or may be formed continuously in the longitudinal direction of the decorative cap B. It is also possible to form

As shown in Fig. 2 fbl, the paving board C consists of a main body part 8 and a waterproof protrusion 14.As for the materials, the main body part 8 is made of hard plastic and the waterproof protrusion 14 is made of soft plastic, which are integrally formed by extrusion molding. It is something that forms. To explain in more detail, the main body part 8 is made up of a nailing piece 9 and a part for the fitting part, and the cross section is formed into a substantially rectangular shape. This is the part that is fixed using a fixture. In addition, the pressure at the fitting part is determined by the two guide pieces 11 bent upward at approximately the center of the nailing piece 9, and both guide pieces 1
1, the fitting groove 12 is formed into a substantially U-shaped cross section, and a fitting claw 13 is provided protruding from the inner surface of the fitting groove 12. This fitting part rule is a part that fits the engaging part of the decorative cap B, and the fitting claw 13 is combined with the engaging protrusion 7 of the decorative cap B, so that the decorative cap B is separated from the batten board C. This is to prevent this from happening. In addition,
The fitting claw 13 can be formed into any desired shape such as a substantially triangular cross section as shown in the figure, or an arc shape or a trapezoidal shape (not shown), and the forming range thereof may be continuous as shown in the figure, or Alternatively, although not shown, it is also possible to form them at intervals or to form them asymmetrically. In addition, the guide piece 11 functions as a guide when engaging the engaging part of the decorative cap B with the fitting part, and also functions as a contact surface and a waterproof surface when applying elasticity and wall material construction. It is. Furthermore, as shown in the figure, the waterproof protrusion 14 is formed in the shape of an inclined tongue protruding toward the fitting part side, and is made of soft plastic, so that when a vertical joint is formed, as shown in FIG. The waterproof protrusions 14 are deformed with elasticity by the wall material, preventing water from entering through the joints and deformation due to wind pressure, resulting in joints with greatly improved waterproof properties. Note that the direction of inclination of the waterproof protrusion 14,
The number of formations is arbitrary and is not particularly limited.

Here, the dimensional relationship of each part will be briefly explained.

Now, the width between the ends of the wall material at the vertical joints as shown in Figure 1, Figure 2+al, (b) is Wl, the width between the guide pieces 11 of the siding board C is W2, and the nails are driven. The height from the piece 9 to the mating claw 13 is hI, and the width on the cosmetic surface of the cosmetic camp B is W3.
, the height from the end of the inclined decorative surface 3.4 to the engagement protrusion 7 is h2
, when the thickness of the waterproof protrusion 14 is t and the thickness of the wall material is d, V/+ # W2 , Ws > V/+, h, fh
2- There is a relationship of t = d. This relationship is cosmetic; when Toyasobu B is inserted into the siding board C, the engaging protrusion 7 engages with the fitting claw 13, and the inclined decorative surface 3.4 on the decorative surface part is securely in line contact with the decorative surface of the wall material. Moreover, the waterproof protrusions 14 come into surface contact with the wall material, resulting in a vertical joint structure with enhanced design, waterproofness, and engagement force.

Next, a construction example will be briefly described using FIG. 1.

First, the nailing pieces 9 of the siding board C are driven with nails F into the part of the wall base E consisting of studs, main pillars, rims, waterproof sheets, etc., where the joiner A is to be used, and fixed.

Next, the wall material is sequentially brought into contact with the left and right sides of the guide pieces 11 of the siding board C, and is fixed onto the wall base E via the nails F, and the wall material is constructed from the base to the girder. Next, vertical joints as shown in the makeup character are formed. In this way joiner A
By forming vertical joints, it is possible to fix the decorative surface part 9 on the top of the nailing piece 9 with a fixing tool such as a nail, so the width relationship between the decorative surface part and the nailing piece 9 can be set freely. . Further, since the decorative camp B engages with the fitting portion of the paving board C after the wall is formed, it will not receive any dents or scratches caused by the nailing film. In addition, makeup cap B
Since it covers the edges of the wall material, even if the edges of the wall material are not aligned in a straight line, it will not appear on the outside, and it will form a vertical joint that is rich in design, aesthetics, and waterproofness. becomes possible. Moreover, the decorative cap 7 B has a fitting claw 13 and an engaging protrusion 7.
Since they are securely locked together, they will not come apart. Also,
Since the waterproof protrusion 14 is made of hard plastic, it is pressed by the wall material and makes surface contact with the wall material with added elasticity, resulting in a vertical joint structure with significantly improved waterproofness.
