Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting structure for exterior panels suitable for application to roofs and exterior walls.

BACKGROUND ART Conventionally, exterior materials, so-called folded plates, which are formed by bending a plate to form peaks, have been widely used, for example, as roofing materials.

This folding plate has bolt holes drilled therein and is used by being attached to a structural member of a building, such as a beam, using bolts and nuts.

The installation required time and effort to align the bolt holes and tighten the bolts, resulting in poor work efficiency and the bolt holes causing leaks and corrosion.

The present invention has been made in an attempt to solve these difficulties, and its gist consists of a bulge extending in an arc shape to the left and right of the top and a depression constricting inward in an arc shape following the bulge. It consists of an exterior plate formed with a mountain portion having a ridge portion and a fixture for attaching the exterior plate. The locking portion has a smooth outer surface by bending both left and right ends of the plate piece inwardly, and the remaining both sides are also bent inwardly, and the locking portion has a smooth outer surface. The exterior plate mounting structure is characterized in that the bulging portion is elastically fitted into the locking portion.

Next, an example of the present invention will be explained with reference to the drawings.

1 and 2 show an example of the exterior plate used in the present invention, and FIGS. 3 and 4 show one embodiment of the mounting structure for the exterior plate of the present invention.

In the figure, reference numeral 1 denotes an exterior plate, and a plate body having a predetermined width and length is bent to form a peak portion 11.

Among the peaks 11, lla is formed in the middle part of the plate, and one or more threads may be provided as necessary.

11b and 11c are peaks formed along the side edges of the plate body, and when a plurality of exterior plates are arranged side by side and joined together, the peaks are formed on top of the peak 11b. 11c
is fitted.

Each of the mountain parts 11 has a bulge part 12 that projects in an arc shape from the left and right sides of the top thereof, and a recess part 13 that constricts inwardly in an arc shape following the bulge part 12.

Examples of the plate body used for the exterior plate 1 include galvanized steel plates, steel plates coated with vinyl chloride resin, and other anticorrosion-treated steel plates, other metal plates such as aluminum plates, and plastic plates.

2 is a locking portion, and the exterior plate 1 is fitted into the locking portion 2 at the bulging portion 12 thereof.

For the locking part 2, a plate piece made of a steel plate thicker than the exterior plate 1 is used, for example, and both ends 21.21 of the locking part 2 have a first bent part 211 and a second bent part 212 at the tip, respectively, forming an obtuse angle. When the bulging part 12 is fitted, the first bent part 211 is at a position near the top of the mountain part 11, and the second bent part 212 is bent inward at three places. The outer surface of the plate piece from
It is inscribed in 2.

It is preferable that both of these bent portions 211 and 212 be bent smoothly so that no corner portions are formed.

Further, the leading edge of the end portion 21 may be further rolled inward so that the end surface is hidden.

Note that both sides 22.22 of the plate piece are also bent inward.

By bending both sides 22 in this way, when fitting the exterior plate 1 to the locking part 2, the inner surface of the exterior plate 1 will be aligned with the side sides 2.
This prevents the edges of the locking portion 2 from being damaged, and also increases the rigidity of the locking portion 2 itself.

Reference numeral 3 denotes a leg portion made of a steel plate, and the rigidity is increased by bending the side edges to form a reinforcing edge 31.

One end 32 of this leg portion 3 is attached to the back surface of the top plate portion 23 of the locking portion 2, and the other end 33 is attached to a structural member of the building, such as a beam.
By being attached to the locking portion 2, the locking portion 2 is brought into a protruding state.

Note that the leg portion 3 extends from the top plate portion 23 of the locking portion 2 to the side edge 2, for example.
It may be made integral with the locking part 2 by providing a tongue piece extending in two directions and bending it downward.

In the present invention, the locking portion 2 and the leg portion 3 constitute a fixture.

The exterior plate of the present invention is attached as follows.

That is, a predetermined number of locking portions 2 are arranged on the left and right in accordance with the spacing between the peaks 11 and 11 of the exterior plate 1, and a plurality of locking portions 2 are also arranged at predetermined intervals along the ridgeline direction of each peak 11. , each locking part 2 is attached to a beam 4 by a leg part 3.

In addition, when installing, both ends 21. of each locking part 2.
21 is aligned in the direction in which the bulging portion 12 of the exterior plate 1 extends.

Attach the exterior plate 1 to the locking part 2 by first attaching it to the peak part 1 on one side.
1b, then the adjacent ridge 11a, and so on until the ridge 11c on the other side is fitted by the bulging portion 12 of the ridge 11.

Fitting at each peak 11 is performed at both ends 2 of the locking portion 2.
1. First, on one of the 21 left and right bulges 1 of the mountain part 11.
2.12, and then wrap the inner surface of the remaining bulge 12 along the other end 21.

During fitting, the recessed part 13 is once expanded by the pressure from the end 21 of the locking part 2, but after the end 21 begins to pass, it contracts again, and the outer surfaces of both ends 21 and 21 are brought into contact with the inner surface of the bulge 12. A tight fit is achieved.

Both end portions 21.21 of both end portions 2 of the locking portion 2 may be entirely bent in an arc shape along the inner surface of the bulging portion 12, as shown in FIG. In order to reduce the pressing force that the bulging part 12 receives from the locking part 2 and to perform the work smoothly, as in the above example, the end part 21 of the plate piece has a first bent part forming an obtuse angle. 211 and a second bent portion 212 at the tip.
It is better if it is bent inward at three points.

When fitting the bulging portion 12 to the locking portion 2, the first bent portion 211
This is because the degree to which the outer surface of the end portion 21 of the plate between the second bent portion 212 and the second bent portion 212 presses against the inner surface of the bulged portion 12 is reduced.

Also, the leg portions 3 may be produced by separating one leg portion 3 for each locking portion 2 as in the above-mentioned example, but for example, a band-shaped steel plate is attached to the peak portion 1 of the exterior plate 1. , 1 may be bent to match the spacing and number of legs 3, so that a plurality of legs 3 may be made in a row at predetermined intervals.

In the mounting structure of the exterior plate of the present invention, the exterior plate is attached by being elastically fitted into the locking part at the bulging part, so the causes of leakage and corrosion due to bolt holes are eliminated, and the installation is easy. The work becomes easier, more efficient, and faster.

In addition, the exterior plate is formed with a crest having a bulge extending in an arc from the left and right sides of the top and a concave part constricting inward in an arc following the bulge, into which the plate is fitted. The locking part is
Both ends and sides of the plate are bent inward to make them smooth and highly rigid.
The fitting of the exterior plate is done easily and effortlessly due to the elastic effect.
In addition, once fitted, the exterior plate and the locking part are in close contact with each other, and any external force in the direction of removing the exterior plate will cause the locking part to expand, so it will not come off and there is no risk of it falling off. It becomes.

In addition, since the locking portion has both ends and both sides of the plate piece bent inward, unlike a case where the end face of the plate piece presses against the inner surface of the bulging part of the exterior plate, Since the pressure is applied using the smooth outer surface of the plate, there is no risk of the pressing force being concentrated locally, and therefore the exterior plate will not be damaged by being pushed up or broken through by the locking part. It becomes.
