In the floor plate B, the waterproof fin 7 and the waterproof piece 8 are made of a soft synthetic resin material (plastic material).
The other parts are made of a hard synthetic resin, and as shown in FIG. 1, the waterproof fin 7 adheres to the end of the wall material E in a deformed state, and the elasticity (restoring force) of the waterproof fin 7 causes the wall to close. The end of the material E is kept waterproof and airtight, and the waterproof piece 8 adheres to the back surface of the metal decorative cap C in a deformed state as shown in FIG. This prevents the engaging portion 12 of the metal decorative cap C from rusting and can maintain the engaging force for a long period of time.

[0018]

As described above, according to the vertical joint structure of the present invention, since the metal decorative cap is fitted and integrated via the synthetic resin pawl, the space between the decorative cap and the pawl is provided. Because there is no thermal bridge, no dew condensation occurs inside the skeleton on the back of the slab, and corrosion of the skeleton can be prevented. Insole th plate also can be formed in any shape for an extruded product made of synthetic resin,
The formation of the multi-stage fitting pieces, waterproof fins, and waterproof pieces is simple. Since the multi-stage fitting piece is formed on the synthetic resin floor plate, it can be adjusted by the engagement depth according to the wall material thickness. The engagement between the fitting piece of the synthetic resin floor plate and the engaging claw of the metal decorative cap is reliable and strong.
Since the waterproof fin made of a soft synthetic resin material is pressed by the wall material, the pressing force appropriately acts on the fitting groove, and the decorative cap does not come off. A waterproof piece made of a soft synthetic resin material is always pressed by the back surface of the decorative surface of the metal decorative cap and closely adheres in a deformed state, preventing rainwater and the like from entering into the fitting groove, and forming a metallic makeup. By preventing the rusting of the engaging portion of the cap, the engaging force can be maintained for a long time, and the metal decorative cap can be prevented from peeling off. Since the waterproof fin made of a soft synthetic resin material is always in close contact with the end of the wall material under elasticity, the waterproofness and airtightness are maintained. There are features and effects such as.
