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 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. 9, a decorative cover a and a joiner b made of a thin iron plate and having a hat-shaped cross section are used to project a protruding portion a of the decorative cover a. 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 front surface of the panel c and the back surface of the decorative cover a on both left and right sides, and the fixing tool β
A method has been generally used in which the upper groove is filled with a backup material e and a sealing material f 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, and dew condensation occurred, and the structure 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 a, which is a surface decorative material, may be peppy, distorted, bent, or the like due to the impact and vibration of the fixture β being struck. It required skill.

[0004]

SUMMARY OF THE INVENTION In order to eliminate the above drawbacks, the present invention provides a decorative cover with a horizontal decorative surface and a substantially central portion of the decorative surface downward and with a substantially concave shape. An elongated cross section of the joiner is formed by forming a long groove from the protruding fixing groove and a buffer portion that is bent in the middle of both side walls of the fixing groove outward or inward in a substantially U-shape approximately parallel to the decorative surface. A horizontal installation surface and a rising portion that protrudes in a substantially convex shape from the center of the installation surface upwards are formed into a hat-shaped elongated body, and the fixing groove of the decorative cover and the riser of the joiner are formed. The parts are connected by a fixture so that they face each other through a fireproof heat insulating material, and the end of the building panel is inserted between the decorative surface of the decorative cover and the installation surface of the joiner to form a vertical joint. As a result, the thermal insulation and airtightness of the vertical joints are improved, and thermal bridges are prevented. Therefore, when preventing the formation of dew condensation and improving the fire resistance performance, and further when placing a fixture that connects the decorative cover and the joiner, the buffer part collides with the surface of the panel and functions as a stopper. It is possible to prevent over-tightening of the fixture, which allows the fire-resistant heat insulating material to have elasticity and cushioning properties.
The present invention proposes a vertical joint structure in which the fixing depth of the decorative cover is constant and distortion and deformation due to over-tightening of the fixture can be prevented.

It serves to prevent the decorative cover A from being distorted or deformed due to excessive tightening of the tool β or impact of penetration.

As shown in the figure, by forming the buffer portion 4 on the outside of the fixing groove 2, when the fixing tool β is driven, the buffer portion 4 collides with the surface of the panel C and functions as a stopper. It is possible to prevent the fixture β from being overtightened. As a result, even if the fireproof heat insulating material D described later has elasticity and cushioning properties, the fixing depth of the decorative cover A becomes constant, and it is possible to prevent distortion and deformation due to over-tightening of the fixture β. It is a thing.

Further, the tongue piece 5 is formed by folding back both end edges of the decorative surface 1 to prevent danger.

The joiner B is, for example, as shown in FIG. 4, formed into a long body by molding the same material as that of the decorative cover A by the same method. The cross-sectional shape is formed in a hat shape from a horizontal installation surface 6 and a rising portion 7 that protrudes upward in a substantially central portion of the installation surface 6 and in a substantially convex shape.

The joiner B functions as a base material for vertical joints. As shown in FIGS. 1 and 2, the joiner B is continuously installed vertically on a wall base α made of a steel frame base or the like, and This is a part where the installation surface 6 is fixed to the wall base α using a fixing tool β such as a blind rivet. The installation surface 6 is a portion on which the panel C is laid, and also functions as a base plate, a waterproof plate, and an airtight plate for the vertical joints.

The rising portion 7 functions as a guide when the panel C is laid on the installation surface 6, and is also a portion above which the decorative cover A is fixed via the fireproof heat insulating material D.

Further, in FIG. 4, to prevent danger, a tongue piece 8 is formed by folding both end edges of the installation surface 6 to the front side, and a mountain shape is formed in the installation surface 6 along the longitudinal direction. One or more protrusions 9 (two protrusions in the figure) are formed. Even if rainwater or the like flows from the surface of the panel C, the ridges 9 function as raindrops and quickly discharge the water toward the base. It prevents the corrosion of α and also prevents the formation of dew condensation, mites and molds.

The panel C is a metal panel, a metal sandwich panel, a ceramic panel, an ALC panel, an extruded hollow cement board, a PC board or the like, which is a horizontal type, a vertical type, or a box type general type. It uses a lightweight fireproof panel made by sandwiching both sides with steel sheets made of thin metal as a core material.

As shown in FIGS. 1 and 2, the refractory heat insulating material D is filled in the grooves formed by the end portions of the left and right panels C and the rising portions 7 of the joiners B, and is made of metal. The decorative cover A and the joiner B are separated from each other to prevent the thermal bridge, so that the fire resistance and the heat insulating property of the vertical joint are mainly improved, and the occurrence of dew condensation and the thermal bridge are prevented. 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 can.

Fix with rivets at β. In addition, the wall base α is provided in advance in a position corresponding to the mounting length of the panel C, at a position where a vertical joint is formed.

Next, using the rising portions 7 as guides on the installation surface 6 of the joiner B, the panels C are laterally stretched from the base direction to the eaves direction and fixed on both sides in order. Then, the refractory heat insulating material D is filled in the concave groove surrounded by the rising portion 7 of the joiner B and the end portion of the panel C.

Further, the fixed groove 2 of the decorative cover A is brought into contact with the filled fireproof heat insulating material D, and the fixed groove 2 is driven by a fixing tool β such as a self-drilling screw screw to vertically move the decorative cover A. It is attached and fixed on the rising portion 7 of the joiner B. At this time, the cushioning portion 4 of the decorative cover A comes into contact with the surface of the panel C, so that it serves as a positioning guide and the fixing depth of the decorative cover A can be made constant. Further, even if the fireproof heat insulating material D has elasticity and cushioning property, the buffer portion 4 functions as a stopper to prevent overtightening of the fixture β, and at the time of mounting the fixture β at the time of mounting the fixture β. It is possible to improve the aesthetic appearance by absorbing the vibrations and shocks, preventing distortion, pebbles, and bending of the makeup surface 1 of the makeup cover A.

Finally, the fixing groove 2 of the decorative cover A, the back surface 1a of the decorative surface 1 and the space between the front surface of the panel C are filled with a backup material E and a sealing material F, respectively, to form a complete vertical joint structure of water stop.
