Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an exterior panel mounting structure with excellent waterproof properties.

Conventional technology and its problems Conventionally, in order to attach exterior panels to a base material, one end edge of one panel and the other end edge of an adjacent panel are engaged with each other, and one panel is fixed to the base material. However, many of the structures were installed by repeating this process one after another.

However, although these items are waterproof in normal rain, during storms, the edges of adjacent panels that are engaged with each other are curved due to strong winds, creating gaps that allow rainwater to enter the panels. There was a risk that water could flow into the building, seep into the underlying material, and flood the building.

Purpose of the invention The present invention provides an exterior panel mounting structure that eliminates the above-mentioned drawbacks, provides sufficient waterproofing even under strong winds, and is easy to construct.

Summary of the invention In order to achieve the above-mentioned object, the present invention forms a panel with a top piece, an upper side piece, and a lower side piece having a roughly shaped cross section, and the upper side piece has an inverted cross section. An inclined piece and a mounting piece are arranged in a row, a bent piece bent upward is provided on the mounting piece, a bent piece bent downward is provided on the inner surface of the top piece, and a bent piece bent downward is provided on the edge of the lower side piece. The panel mounting piece is attached to the base material, and the upwardly bent bending piece and the inclined piece are each connected to the downwardly bent bending piece and the locking part of the panel adjacent to the top. It has an exterior panel mounting structure that is crimped and fixed.

The feature of the present invention is that the downwardly bent bent piece of the panel adjacent to the upwardly bent bent piece of the panel is crimped, and at the same time, the locking part provided on the lower side piece of the panel adjacent to the inclined piece of the panel is pressed. It also has a configuration in which it is crimped and fixed.

Therefore, wind and rain that enters between the side pieces of adjacent panels is first affected by the crimped part between the inclined piece and the locking part, and then by the inclined piece, the upwardly bent bent piece, and the top of the adjacent panel. Intrusion is successively prevented by the air layer in the cavity formed by the upper and lower side pieces, and by the crimped portion between the upwardly bent bent piece and the downwardly bent bent piece. In the unlikely event that rainwater enters, it enters the groove formed by the upwardly bent bent piece and the mounting piece, flows sideways and can be discharged to the outside.

In the present invention, sufficient waterproofing effect can be obtained without using waterproof packing, but if waterproof packing is filled around the upwardly bent bent piece and the downward bent piece, rainwater will not flow into the groove. Since there is no inflow, a more complete waterproofing effect can be obtained.

Example Embodiments of the invention are explained in the drawings.

In Figures 1 to 3, a long panel 1 made of an aluminum profile has a top piece 2, an upper side piece 3 that is slightly inclined outward, and a lower part that stands up with only a few edges left. The side piece 4 is formed into a substantially square cross section. At the edge of the upper side piece 3, an inclined piece 5 which is inclined slightly downward with respect to the top piece 2 and a mounting piece 6 which is parallel to the top piece 2 are formed so as to have a rectangular cross section.
The mounting piece 6 has a bent piece 7 at its upper end, a minute V-groove 8 carved in the upper part, and an upwardly bent bent piece 9 with an approximately L-shaped cross section on the lower part, which protrudes from the top piece 2 side. It has been done. An upwardly projecting upper piece 10 of the bent piece 9 is formed to be inclined at approximately the same angle as the inclined piece 5.

At the edge of the lower side piece 4, a sloped piece 5 is attached to the bottom surface.
A locking portion 11 formed so as to be located approximately at the center of the surface is continuously provided. The inner surface of the top piece 2 has an almost inverted L cross section consisting of an upright piece 12 and an engaging piece 13.
A bent piece 14 bent downward in the shape of a shape is provided in a protruding manner.
The engagement piece 13 is formed to be slightly closer to the top piece 2 than the edge of the upper piece 10 of the bent piece 9, with the top piece 2 as a reference, and an R portion is provided on the edge. Furthermore, when the locking part 11 of the panel 1 adjacent to the top is crimped to the center of the inclined piece 5, at the same time, the engagement piece 13 of the bent piece 14 is inserted into the bent piece 9 of the adjacent panel 1 and crimped. It is protruded in a position where it can be used.

To attach the panel 1 to the base material 15, first, the mounting piece 6 of the panel 1 is brought into contact with the lowermost part of the base material 15, and screwed in with the screw 16 inserted at the V-groove 8 position. Next, the adjacent panel 1 from above
(FIG. 1), the locking portion 11 of the panel 1 from above collides with the center of the inclined piece 5 of the panel 1 below. At this time, the engaging piece 13 of the bent piece 14
is inserted by bending the upper piece 10 of the lower panel 1, and at the same time the locking part 11 and the inclined piece 5 are crimped, the two bent pieces 9 and 14 are also crimped.

The panels 1, 1 fixed by crimping at these two places form an air layer by providing a void 17 with the inclined piece 5, the upwardly bent piece 9, the lower side piece 4, the top piece 2, etc. Furthermore, a groove 18 is formed by both bent pieces 9 and 14 and the attachment piece 6. Mounting piece 6 of upper panel 1 fixed to lower panel 1
is fixed to the base material 15 with screws 16 as described above. In this way, adjacent panels 1 are sequentially inserted from above, crimped and fixed, and the panels 1 are attached to the outer wall.

During strong winds, wind and rain that enters between the upper and lower side pieces 3 and 4 are first blocked by the crimped part between the inclined piece 5 and the locking part 11, and the wind and rain that overcomes this are also strengthened by the air layer in the empty chamber 17. weakened and further bent on both sides 9,
It is also prevented at the crimped portion between 14 and 14. In the unlikely event that rainwater enters, it flows laterally through the groove 18 and is discharged to the outside.

In the embodiment shown in FIG. 4, one or both of the bent pieces 9 and 14 of the panel 1 are filled with a waterproof packing 19 made of an elastic material in the previously described embodiment.
This is an attempt to obtain a more complete waterproof effect.

Effects of the invention Since the invention has the above-described configuration, it is possible to prevent rainwater from entering even under considerable wind pressure, resulting in a highly waterproof panel mounting structure. What's more, the installation is extremely simple, just inserting the panels one by one from above, pressing them down, and securing them with screws.
It can significantly shorten construction time and reduce construction costs.
