Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of longitudinal joints, that is, longitudinal joints of drywall materials (hereinafter simply referred to as wall materials) used in architecture and structures.

[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 body is formed, a joint is formed by butting the wall materials in the longitudinal direction, so-called vertical joints.There is a method of simply butting the vertical joints and planting caulking material in the joint. However, caulking material changes due to weather resistance.
Due to UV deterioration, there was a drawback that waterproofness 1 and designability could not be maintained for a long period of time. Furthermore, with wall materials that use synthetic resin foam as the core material, deformation of the metal plate that is the surface material at the longitudinal ends tends to occur (and it was not easy to install caulking material. Because the wall material made of this material is brittle, the edges of the wall material are prone to chipping (there was a disadvantage that the vertical joints lacked aesthetics. For this reason, there is a method of using joiners with an H-shaped cross section for the 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. There were some shortcomings.

[Purpose of the invention]

In order to eliminate such drawbacks, the present invention has two members: a slat plate formed from a horizontal portion and a fitting portion into a round shape in cross section, and a decorative camp formed into a T-shaped cross section from a decorative surface portion and an engaging portion. Using a joiner for vertical joints that forms an H-shaped cross section by combining decorative camp and siding boards, after fixing the siding boards, construct the wall material, and after installing the wall material, install the The fitting part of the decorative cap is fitted to the fitting part of the batten to facilitate construction, and the fitting part of the batten is formed with a fitting claw that protrudes inward, and the decorative cap is The engaging portion of the camp is formed with an engaging piece that protrudes outward, and the engaging piece of the makeup camp is prevented from coming off by engaging the engaging claw of the padding plate with the engaging piece of the decorative camp.
In addition, elasticity is applied to the contact surface between the back of the cosmetic cap and the edge of the wall material.
This relates to a vertical joint structure in which a molded elastic packing material made of rubber-based or EPDM-based material with cushioning and waterproof properties is planted to form vertical joints with improved waterproofness, airtightness, workability, and design. be.

Furthermore, since the decorative camp C engages with the fitting portion ↓ of the siding board B after the wall is formed, it will not suffer from dents or damage caused by the nailing film. Furthermore, makeup camp C
Since the shape corresponds to the decorative surface of the wall material, the line of the horizontal joint formed by the horizontal cladding will not be cut off (,
It becomes possible to form a wall body rich in design. Moreover, since the fitting claw 7 and the engaging piece 11 are securely engaged with each other, they do not come off, and the packing material 13 reliably closes the gap between the decorative cap C and the edge of the wall material, greatly improving waterproofness. This will improve the results.

〔Effect of the invention〕

As described above, according to the vertical joint structure according to the present invention, since the end portion of the wall material is covered with the decorative surface portion of the decorative cap, which is a part of the joiner, it is possible to form a wall body that is rich in aesthetics. At the same time, the horizontal joints will not be separated. Moreover,
Since the joiner is composed of two members: the siding board, which is the part that fixes the joiner to the wall base, and the decorative camp, which covers the end of the wall material, the siding board can be easily nailed, improving workability. In addition, since the decorative cap is attached after the siding boards and wall materials are fixed, no excessive force is applied to the decorative cap, which prevents damage to the surface of the wall material and prevents the decorative camp from deforming. be able to. Moreover, since the decorative cap can be attached by simply fitting it into the padding, it does not cause any dents or deformation.

In addition, the engagement force is strengthened by the engagement piece of the decorative cap 7, the mating claw of the siding board, and the cushioning properties of the packing material, so that it will not come off, even if the decorative surface of the wall material has some unevenness. However, there is no reduction in waterproofness. The waterproof strip ensures the waterproofness of the horizontal joints. Furthermore, since there is no need to insert the wall material into a joiner, it is easy to measure the dimensions of the wall material, making construction easier. It has the following characteristics.
