Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of vertical joints formed at the time of connecting building panels useful for constructing an outer wall and an inner wall of a building, and more specifically to an interior. The present invention relates to a vertical joint structure in which a space is formed to prevent a capillary phenomenon to improve waterproofness.

[0002]

2. Description of the Related Art Conventionally, as a structure for accommodating a vertical joint of this kind, as shown in FIG. 14 (a), a fixing member β is used on a frame α made of a steel frame base or the like, and a thin iron plate has a hat-shaped cross section. It is intended to covering the decorative cover a and Joyner b by building panel c edge long as the method, by facing the protruding portion b ₁ between the projecting portions a ₁ and Joyner b of the decorative cover a Connected with a fixing tool β such as a blind rivet, and the surface of the building panel c on the left and right sides and the decorative cover a
14 and the inside of the groove on the fixture β with the backup material d and the sealing material e, or FIG.
As shown in (b), using a building panel c in which a box fold piece c ₁ is formed at the end in order to improve the adhesive strength of the sealing material e, the sealing material e is filled on the joiner b and vertical joints are formed. Has generally been done.

[0003]

However, in the structure as described above, the infiltration of rainwater or the like is prevented only by forming the backup material d and the sealing material e. However, there is no escape route for the rainwater that has penetrated into the interior of the building, and it remains inside the building body α and corrodes the building body α. Moreover, in the structure of FIG. 14A, there are problems in terms of workability and cost because the backup material d and the caulking material e are used in many portions (three locations). Further, when the backup material d is formed, the position where the backup material d is formed becomes deeper or shallower because the position is not accurate, which changes the embedding thickness of the sealing material e, resulting in the sealing. The amount of the material e used was changed, resulting in a vertical joint structure having problems in cost, waterproofness, and adhesive strength.

[0004]

Further, in the figure, in order to prevent danger, a tongue piece 6 in which both end edges of the installation surface 4 are folded back to the front side is formed. Further, the tongue piece 6 functions as a rain catcher and quickly discharges it toward the base even if rainwater or the like flows in from the surface of the construction panel F by any chance. It is intended to prevent the corrosion of the frame α and also prevent the occurrence of dew condensation, mites and molds.

Further, as shown in FIG. 3, the inorganic sheet C formed on the joiner B is a decorative cover A made of metal.
By separating the space between Joiner B and Joiner B to prevent a thermal bridge (heat conduction) and blocking the space between the back surface of building panel F and Joiner B, fire resistance, flame resistance, and heat resistance of vertical joints are mainly achieved. To improve fire resistance and prevent dew condensation. In this way, even in the unlikely event of a fire, the heat and smoke of the flame generated from the inside or outside of the building will be blocked from being transmitted to the outdoor side or indoor side, and the vertical joint structure will pass the fireproof 1 hour test. Is something that can be done. Examples of the material include rock wool felt, ceramic wool, glass wool, asbestos, gypsum board, water glass bond, various inorganic foams, ultra-high density phenol foam, inorganic fire-resistant caulking agent,
It is an inorganic type that is strong against fire and consists of one kind of.

Examples of the material thereof include foamed polyethylene, chloroprene rubber, EPT rubber, synthetic rubber beads, bond breakers and the like which are generally commercially available.

The extruded material E ₁ such as EPDM is made of a joint material E extruded as shown in FIG. 4, and generally, for example, EPDM, EPM, polyvinyl chloride type, chloroprene type, chlorosulfonated type. One having elasticity such as polyethylene type, ethylene propylene type, asphalt impregnated polyurethane type, or one of non-elastic type such as polybutene type, polypropylene type, butyl type and rubber asphalt type is used. In particular, as shown in FIG. 1, when weather resistance, stain resistance, heat resistance, etc. are required to be formed on the exposed portion, weather resistance, stain resistance such as EPDM,
A material having excellent heat resistance, ozone resistance, chemical resistance, etc. is used. In order to prevent the groove E ₂ from being deformed by the fixture head β ₁ of the fixture β when the extruded material E ₁ such as EPDM is inserted and the deformation of the extruded material E ₁ such as EPDM appearing on the surface after the insertion. It is a thing.

The backup material functions as a filling material for preventing three-point adhesion of the sealing material, which will be described later, and as a bulking material for reducing the amount of the sealing material used. Examples of the material thereof include foamed polyethylene, chloroprene rubber, EPT rubber, synthetic rubber beads, bond breakers and the like which are generally commercially available.

The sealing material fills the above-mentioned back-up material and functions as a waterproof material for completing a complete surface waterproof structure, and is generally commercially available as a two-component silicone-based or inorganic fire-resistant caulk.
