A method has been generally used in which e and a sealing material f are filled to form vertical joints on the wall base α.

[0003]

However, in the conventional structure as described above, the vertical joint has only the iron plate, the backup material e, and the sealing material f, and the vertical joint is significantly inferior in heat insulation and airtightness. At the same time, the thermal bridge between the decorative cover a and the joiner b became a problem, which caused dew condensation and was vulnerable to the heat of the flame such as a fire, and was a vertical joint structure that could not pass the fireproof structure certification test. Furthermore, when the decorative cover a and the joiner b are connected, the decorative cover, which is a surface decorative material, may be peppy, distorted, bent, and the like due to the impact and vibration of the fixing device β being placed. Was required.

[0004]

Therefore, in the present invention, the decorative cover has a horizontal decorative surface, two locking pieces protruding downward from a substantially central portion of the decorative surface, and a tip of the locking piece. A locking claw formed to project outwardly is formed into a T-shaped elongated body, and the locking body has a horizontal holding surface, a substantially central portion of the holding surface is downward, and A fixed groove protruding in a concave shape,
Forming a long body from the engaging claw that engages with the locking claw of the cosmetic cover by projecting the middle of both side walls of the fixing groove inward, and the joiner has a substantially cross section of the horizontal installation surface and the installation surface. With a substantially central portion upward, and from a rising portion that protrudes in a substantially convex shape, with a member formed into a long body formed in a hat shape,

The fixing groove of the locking body and the rising portion of the joiner are connected by a fixing tool so as to face each other through a fireproof heat insulating material, and a construction panel is provided between the holding surface of the locking body and the installation surface of the joiner. Since the structure is constructed by inserting the ends of the vertical joints, the heat insulation and airtightness of the vertical joints are improved,
Since the heat bridge is prevented, the occurrence of dew condensation is prevented and the fire resistance is improved, and moreover, since the decorative claw of the decorative cover is locked to the engaging claw of the locking body, the decorative cover is attached. Even if the locking body is slightly deformed or distorted due to over-tightening of the fixture that secures the joiner and the locking body, or shock or vibration when fixing, it will be covered with a cosmetic cover, so it is beautiful. It proposes a vertical joint structure with good properties.
