Description

[Detailed Description of the Invention] This invention relates to a watertight connection structure for metal wall materials, which has a plurality of air chambers in the connecting portion, which is used for connecting metal wall materials in buildings.

Conventionally, as a connection structure for metal wall materials in a building, as shown in FIG. A groove-shaped portion 15 having a trapezoidal cross section is bent and formed in the middle part of the back side overlapping connection plate 14 of the other metal wall material 10B in the width direction of the overlapping connection plate, and each overlapping connection plate 11, 14 has a width thereof. It is known that the bolt is fastened by a fastener 7 such as a drill screw that is inserted into the intermediate part and screwed onto a support member 16 such as a rim.
Furthermore, as shown in FIG. 2, there is also known a connection structure in which a sealing material 17 is filled in the outer hollow portion between the front side overlapping connection plate 11 and the back side overlapping connection plate 14 in the connection structure as described above.

However, in the case of the conventional connection structure, if the fastener 7 is strongly tightened, the hollow part of the overlapping connection plate is deformed, so it is not possible to create a stable air chamber, and the third
As shown in the figure, the distal end of the flange 13 rises, resulting in a poor appearance.Furthermore, the overlapping connection part requires many bending operations, and in the case of the connection structure shown in Fig. 2, filling with the sealing material 17 is required. Therefore, the connection work is complicated.

The object of this invention is to provide a watertight connection structure for metal wall materials having a plurality of air chambers at the connection part, which advantageously solves the above-mentioned problems.

Next, this invention will be explained in detail using illustrated examples.

FIG. 4 shows an example of the metal wall material 1 used in this invention, in which an inclined side plate 19 and a front overlapping connection plate 2 are sequentially bent and connected on one side in the width direction of a metal plate 18. , and the front overlapping connection plate 2 has an outer groove portion 3 and an inner groove portion 4 having an obtuse V-shaped cross section and extending in the longitudinal direction of the overlapping connection plate and spaced apart from each other in the width direction of the overlapping connection plate. is bent, and the edge of the front overlapping connection plate 2 constitutes one opening edge 5 of the outer groove-shaped portion 3, and furthermore, the edge 2 of the outer groove-shaped portion 4 on the middle side of the wall material
0 is common to the tip of the inclined side plate 19, and the edge portions 5, 20 protrude a small amount δ from the back side of the flat plate portion 21 between the grooved portions 3, 4. Further, on the other side of the metal plate 18 in the width direction, an inclined side plate 22, a flat back side overlapping connection plate 6, and an inclined rising plate 23 are sequentially arranged in a bent manner.

FIG. 5 shows a watertight connection structure of metal wall materials having a plurality of air chambers at the connection part using the metal wall materials shown in FIG.
The front side overlapping connection plate 2 of A is connected to the other metal wall material 1B.
The back side of the back side overlapping connection plate 6 is in contact with a support member 16 such as a metal rim, and a fastener 7 such as a drill screw is attached to each groove-shaped portion. It is passed through each of the overlapping connection plates 2 and 6 between 3 and 4 and is screwed onto the support member 16, and the flat plate portions of each overlapping connection plate 2 and 6 are strongly tightened and connected by the fastener 7. Along with
The opening edges on both sides of the groove-shaped parts 3, 4 are brought into close contact with the back side overlapping connection plate 6, and two air chambers 8, 9 are stabilized by each groove-shaped part 3, 4 and the back side overlapping connection plate 6.
is configured.

If wind and rain try to infiltrate through the watertight connection part of the above embodiment, the pressure difference between indoor and outdoor is buffered and reduced in sequence by each air chamber, so that the intrusion of wind and rain is prevented.

When implementing this invention, each of the groove-shaped portions 3,
The cross-sectional shape of 4 may be a right-angled or acute-angled V-shape, or may be an arcuate shape. Also, the edge of the middle side of the wall material of the inner groove-shaped portion 4 and the inclined side plate 19
A narrow flat plate portion may be provided between the tip of the
Furthermore, a protrusion or a groove may be formed in a curved manner in the middle part of the wall material.

Furthermore, as shown in FIG.
4, and the plane 24 may be inclined with respect to the extension plane 25 of the back side of the backside overlapping connection plate 6 such that the edge 5 side is located on the back side of the connection plate.

As in the above embodiment, the opening edges 5 and 20 of each groove-shaped portion 3 and 4 may be made to protrude slightly toward the back side of the flat plate portion 21, or as shown in FIG. If the edges 5, 20 are arranged on the inclined plane 24, when the respective overlapping connection plates 2, 6 are tightened with the fastener 7, the opening edges 5, 20 are arranged on the back side overlapping connection plate 6. Can be strongly pressed against the surface.

According to this invention, an outer groove-shaped portion 3 and an inner groove-shaped portion 3 extending in the longitudinal direction of the overlapping connecting plate and spaced apart in the width direction of the overlapping connecting plate are provided on the front side overlapping connecting plate 2 of one metal wall material 1A. A gutter-shaped portion 4 is formed, and the overlapping connection plate 2 is connected to the other metal wall material 1B.
The overlapping connecting plates 2, 6 are superimposed on the flat back side overlapping connecting plates 6 of are tightly connected, so that even if the overlapping connection plates 2 and 6 are strongly tightened, they will not be deformed, and the opening edges on both sides of each groove-shaped portion 3 and 4 are connected to the surface of the back side overlapping connection plate 6. It is possible to form two independent air chambers 8, 9 with a stable closed cross-sectional shape by bringing them into close contact with each other, thereby improving the watertightness of the polymerization joint of the metal wall material, and furthermore, the surface side polymerization The edge of the connecting plate 2 constitutes the outer opening edge 5 of the outer groove-shaped portion 3, and since no flange is connected to the outer opening edge, the tip of the flange is formed when the overlapping connection is strongly tightened. It is possible to solve the problem of the conventional connection structure in which the sides rise up and deteriorate the appearance, and in the case of the watertight connection structure of the present invention, bending of the overlapping connection part is easier than in the conventional connection structure. Effects such as a small number, simple shape, and easy processing can be obtained.
