[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of vertical joints formed when connecting building panels (hereinafter simply referred to as "panels") useful for constructing an outer wall and an inner wall of a building. More specifically, the present invention relates to a vertical joint structure that has improved waterproofness as a complete surface waterproof structure, and has excellent fire resistance and heat insulation.

[0002]

2. Description of the Related Art Conventionally, as a structure for accommodating a vertical joint of this type, as shown in FIG.
A fixing tool β is used on the upper part of the panel c to cover the end of the panel c with a long decorative cover a made of a thin iron plate and having a hat-shaped cross section, and a joiner b. ₁ and the projecting portions b _{1 of the} joiner b are opposed to each other and connected by a fixing tool β such as a blind rivet, and the back surface of the panel c on both left and right sides, the back surface of the decorative cover a, and the groove on the fixing tool β are backed up. The method of filling with d and the sealing material e has been generally performed.

[0003]

However, in the conventional structure as described above, only the iron plate, the backup material d, and the sealing material e are provided in the vertical joints, and the joints are significantly inferior in heat insulation and airtightness. The heat bridge between the decorative cover a and the joiner b causes a problem, and dew condensation occurs, and the structure is weak against heat of a flame such as a fire. Therefore, in such joint structure which is the weakest point in the wall structure, JIS-
Fire resistance 1 of A-1304 (fire resistance test method for building structures)
It was a vertical joint structure that could not pass the structural certification test of time. Further, when the decorative cover a and the joiner b are connected, the decorative cover a, which is a surface decorative material, may be pegged, distorted, bent, or the like due to the impact and vibration of the fixing device β being placed. Was required.

[0004]

Therefore, in the present invention, an inverted hat is formed from a decorative surface having a substantially horizontal cross section of the decorative cover and a fixing groove protruding downward in a substantially central portion of the decorative surface and in a substantially concave shape. The holding body is formed into a long shape, and a substantially cross section of the locking body is formed into a reverse hat shape by a horizontal holding surface and an insertion groove that is formed by protruding a substantially central portion of the holding surface downward and in a substantially concave shape. A member that is formed into a hat shape with a long body by using a long body and a horizontal installation surface with a substantially cross section of the joiner and a rising portion that protrudes in a substantially convex shape with a substantially central portion of the installation surface upward. Be prepared

The ends of the left and right panels are laid on the installation surface of the joiner, and the retaining surface of the engagement body is made so that the insertion groove of the engagement body and the rising portion of the joiner face each other through the fireproof heat insulating material. Since it is fixed to the surface material of the panel, and the fixing groove of the decorative cover is inserted, abutted and fixed on the insertion groove of the locking body, the structure has vertical joints.
The vertical joint is covered with two members, the locking body and the decorative cover, to improve waterproofness, airtightness, and design, and the fireproof heat insulating material interposed between the locking body and the joiner allows the vertical joint to be improved. By completely separating the front side and the back side of the and preventing the thermal bridge, the fire resistance and heat insulation of the vertical joints are mainly improved, and the occurrence of dew condensation is prevented. In the event of a fire, the heat of the flame generated from the inside or outside of the building is blocked from being transmitted to the outside or inside,

Finally, by filling the gap between the front surface of the panel D and the rear surface of the decorative surface 1 of the decorative cover A and the fixing groove 2 of the decorative cover A with the backup material F and the sealing material G, a complete surface stop is achieved. It forms the vertical joint structure of water.

By forming the vertical joints in this manner, the vertical joints are covered with the two members of the locking body B and the decorative cover A, so that waterproofness, airtightness, and designability are improved. In addition, the front side and the back side of the vertical joint are completely separated by the fireproof heat insulating material E interposed between the locking body B and the joiner C to prevent the thermal bridge, and mainly the fire resistance and heat insulation of the vertical joint are provided. It improves the property and prevents the occurrence of dew condensation. In this way, even in the unlikely event of a fire, it is possible to block the heat of the flame generated from the inside or outside of the building from being transmitted to the outdoor side or the indoor side, and have a vertical joint structure that passes the fireproof 1 hour test. It is possible.

[0043]

As described above, according to the vertical joint structure of the present invention, the fixture does not appear at all on the external appearance of the wall body, and the surface is still waterproof. Since a fireproof heat insulating material is interposed between the locking body and the joiner, the heat insulation and airtightness of the joints are improved, and the front and back sides of the vertical joints are completely separated to prevent thermal bridges and condensation. Moreover, the vertical joints, which are the weakest points against heat, are strengthened, and JIS-A-1
It becomes a vertical joint structure that passes the fireproof 1 hour test of 304 (fireproof test method of building structure part). Even if the core material is an organic material such as a synthetic resin foam (phenolic foam or the like), a vertical joint structure that passes the fireproof 1 hour test is obtained.
Since the two members of the decorative cover and the locking body are present on the surface side of the vertical joint, the vertical joint structure has excellent waterproofness, airtightness, and strength. Due to the impact and vibration of placing the fixture, the decorative cover, which is the surface decorative material, does not have pecks, distortion, bending, etc., and therefore no skill is required for construction. There are characteristics and effects.
