2. Description of the Related Art Conventionally, as shown in FIG. 6, a mounting structure for a roof material of this type includes a falling portion 1a having an eave-side end bent downward and a ridge-side end formed on the metal roof material 1. And a rising portion 1b is formed by bending the metal roofing material 1 upwardly, and the falling portion 1a is provided with a displacing portion 3 which can be elastically displaced up and down in the vicinity of the back surface of the metal roofing material 1 in the mounting posture. A fixing bracket 5 that can be placed and that can fix the rising portion 1b and the falling portion 1a of the metal roofing material 1 is attached to the ground A, and the displacement portion 3 is provided with a folded portion 3a. It has been proposed that a fixing portion 5a is provided on the fixing metal member 5 so as to be able to lock the turn-back portion 3a by overcoming the displacement of the displacement portion 3 by multiplication. In other words, according to the above-described configuration, the metal roofing material 1 having the falling portion 1a provided with the displacement portion 3 is pushed from the outside of the roof so as to slide into the fixing fitting 5, so that the displacement portion 3 An elastic displacement is generated, and based on the elastic displacement, the locking portion 5a of the fixture 5 can be passed over the folded portion 3a provided in the displacement portion 3. Then, based on the overcoming, the folded portion 3a is locked by the locking portion 5a of the fixing bracket 5, so that the metal roofing material 1 can be easily attached and fixed to the ground. Further, since the metal roofing material 1 can be mounted and fixed to the ground surface only by the locking by the locking portion 5a in a state where the metal roofing material 1 is placed on the fixing bracket 5, the metal roofing material 1 can be fixed. The permissible dimensional error at the time of attachment of the material 1 is such that accommodation occurs in the roof inclination direction. As a result, an effect is expected that it is possible to reduce the labor required for mounting the metal roofing material 1 and increase the allowable dimensional error in the roof inclination direction when the metal roofing material 1 is mounted.

[0003]

However, when the above-described displacement portion 3 is provided on the metal roofing material 1, an L-shaped inclined position (between the falling portion 1a and the displacement portion 3) is provided. Or a C-shaped bottomed portion U is formed. By the way, the allowable dimensional error in the roof inclination direction is very useful in mounting the metal roofing material 1 when mounting the metal roofing material 1. However, in severe wind and rain, the clearance allowing the rattling of the metal roofing material 1 is allowed. Is also formed. Therefore, the mist due to the wind and rain enters the mounting space S between the falling portion 1a and the fixing bracket 5, and further, the mist from the rattled folded portion 3a and the locking portion 5a. In addition, it has been pointed out that water droplets in which mist aggregates may enter the bottomed portion U and water may be accumulated in the bottomed portion U.

That is, water accumulates in the bottomed portion U,
Furthermore, if water enters between the members made of metal near the bottomed portion U due to a capillary phenomenon or the like and the water is left as it is, the bottomed portion U or the metal roofing material may be rusted. Therefore, it is considered that there is a possibility that the above-mentioned problem may occur, and a technique for coping with such inconvenience is desired.

Further, the metal roofing material 1 and the fixing member 5
It is thought that if a mist enters the gap between the two, water will accumulate on the ground A, causing inconvenience such as rain leakage.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a metal roofing material which is less likely to be degraded even in the event of wind and rain while maintaining the above-mentioned structure for facilitating attachment and detachment to a roof. It is still another object of the present invention to provide a roofing material that is even more waterproof.

[0007]

In order to achieve this object, a roof material mounting structure according to the present invention is characterized by a structure in which a solar cell 2 is adhered to the surface side.
In order to attach the roofing material 1 to the ground A,
Falling part 1 with eaves-side end bent down to root material 1
a and the rising portion 1b obtained by bending the ridge side end upward.
The metal roofing material 1 can be formed and
The rising portion 1b and the falling portion of the roof material 1
1a is fixed in a state in which water is stopped,
Attach to the ground A and fix the falling part 1a
Near the back surface of the metal roofing material 1 for fixing to the metal fitting 5
The displaceable portion 3 which can be elastically displaced up and down by the falling portion
1a, and a folding part 3a is provided on the displacement part 3.
And by overcoming the elastic displacement of the displacement portion 3
The locking portion 5a capable of locking the folded portion 3a is fixed to the fixing metal.
And the fixing bracket 5 is attached to the ground A.
In the state where the beam is radiated, the falling portion 1a and the rising portion
The part 1b is attached to the fixing bracket 5 by an operation from the outside of the roof.
On the other hand, it is a roof material mounting structure
Thus, the folded portion 3a is engaged with the locking portion 5a.
Seal part 3b elastically abutting on said locking part 5a in a state
Is formed between the falling portion 1a and the displacement portion 3.
Between the bottomed portion U to be formed and the folded portion 3a,
Due to being provided over the width direction of the roofing material 1 , a plurality of folded portions 3 a may be provided in the displacement portion 3 in parallel in the width direction of the metal roofing material 1.

Although the drawings are referred to for explaining the features of the present invention, the present invention is not limited to the drawings.

[Effects] According to the structure of the present invention having the above-mentioned characteristic configuration, the metal roofing material with the falling part to which the elastic fitting having the displacement part is attached is attached to the fixing fitting and the drain plate. By pushing from the outside of the roof to slide it up,
An elastic displacement can be generated in the displacement portion, and the displacement portion can be caused to go over the locking portion of the fixing bracket based on the elastic displacement. Then, based on the overcoming, the folded portion provided in the displacement portion is locked by the locking portion of the fixing bracket, so that the metal roofing material can be easily attached and fixed to the ground. Further, since the metal roofing material is mounted and fixed on the ground surface only by the locking by the locking portion in a state where the metal roofing material is placed on the fixing bracket and the drain board, the metal roofing material is fixed. The permissible dimensional error at the time of installation of the vehicle has flexibility in the roof inclination direction. Further, the displacement portion is provided with a seal portion that elastically contacts the lock portion in a state where the folded portion is engaged with the lock portion, so that the seal portion is used in the case of severe wind and rain. Even if the metal roofing material rattles, the metal roofing material comes into contact with the locking portion so that the metal roofing material can easily follow, and the rattling of the metal roofing material occurs between the locking portion and the displacement portion. An allowable gap is hardly formed. Therefore, even if mist due to wind and rain enters the mounting space between the falling portion and the fixing bracket, further, between the folded portion and the locking portion, mist or mist is aggregated. Water droplets can be prevented from entering the bottomed portion.

[0010] Therefore, it is possible to reduce the labor required for mounting the metal roofing material, to increase the allowable dimensional error in the roof inclination direction when mounting the metal roofing material, and to reduce the size of the metal roofing material. Water intrusion can also be suppressed.
For this reason, it is possible to eliminate the inconvenience such as deterioration due to rust, which is feared in the mounting structure of the metal roofing material proposed earlier.

It is preferable that a plurality of folded portions are arranged on the displacement portion in the width direction of the metal roofing material. With such a configuration, when attaching the metal roofing material, the folded portion is formed. This makes it possible to move over the displacement portion with a small amount of effort over the locking portion of the fixing bracket, as compared with the case where the portion is provided over the entire width in the width direction of the metal roofing material.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the structure of the present invention, and FIGS. 2 to 4 show an attaching operation and a detaching operation of a metal roofing material.

In FIG. 1, reference numeral 1 denotes a metal roofing material that is attached to the ground A when roofing. A solar cell 2 is adhered to the surface side of the metal roofing material 1. More specifically, as shown in FIGS. 2 to 4, a substrate 1 </ b> A on the back side of the metal roofing material 1 is made of a colored zinc iron plate, and an EVA (ethylene vinyl resin) enclosing the solar cell 2 is provided on the front side. (Acetate) resin layer 1B is disposed, and a transparent glass plate 1D is disposed on the surface side of the resin layer 1B, and the three are integrated by the adhesive force of the resin. The reason why the substrate 1A on the back side is made of a colored zinc-iron plate is that the substrate 1A made of the colored zinc-iron plate functions as a non-combustible material and is preferable from the viewpoint of fire prevention. Also, the left and right edges of the metal roofing material 1, that is, the substrate 1 made of the colored zinc-iron plate
A water return portion 1d (see FIGS. 1 and 2) formed by folding the substrate 1A downward in the "Haze" direction is provided at the left and right edges of A.

The metal roofing material 1 is formed with a falling portion 1a having an eave-side end bent downward and a rising portion 1b having a ridge-side end bent upward. The elastic metal fitting 3 made of spring steel, which forms a displaceable part that can be elastically displaced up and down in the vicinity of the back surface of the metal roofing material 1 in the mounting posture, is detachably attached by screws 4 that can be operated from the outside of the roof. And the elastic metal fitting 3 is provided with a folded part 3a that is folded toward the falling part 1a. In addition, the operation of attaching the elastic metal fitting 3 with the screw 4 is, specifically, making a hole for the screw 4 in advance in the falling portion 1a and the elastic metal 3, and attaching the screw 4 to the prepared hole. The workability is improved by screwing.

A fixing bracket 5 on which the metal roofing material 1 can be placed and on which the rising portion 1b and the falling portion 1a of the metal roofing material 1 can be fixed is attached to the ground A. The fixing member 5 is provided with a hook-shaped locking portion 5a which can lock the folded portion 3a by going over the folded portion 3a which multiplies the elastic displacement of the elastic metal member 3. Further, the mounting position of the screw 4 in the vertical direction with respect to the falling portion 1a of the metal roofing material 1 is set to a position below and below the locking portion 5a in a state in which the folded portion 3a is climbed over.

Further, the elastic fitting 3 is elastically in contact with the locking portion 5a to attach a bottomed portion U formed by the elastic fitting 3 and capable of forming a puddle to the metal roof material 1. The sealing portion 3b for sealing the space between the metal roofing material 1 and the mounting space S for performing the mounting operation is provided over the width direction of the metal roofing material 1.

Further, in the lateral direction (so-called “haze” longitudinal direction)
A draining plate 6 on which the respective ends of the metal roofing material 1 adjacent to each other can be placed and which can receive and leak water from gaps between them is arranged in a state of being supported by the fixing bracket 5. The draining plate 6 is a sheet metal member disposed below the gap, and has a falling portion 6a (see FIGS. 1 and 2) formed by bending an eaves-side end downward and a ridge-side end upward. It has a rising portion 6b (see FIG. 2) formed by bending, and a side rising portion 6d (see FIG. 1) formed by bending the left and right ends inward and upward. Is to be performed.

When using such a structure of the present invention,
The metal roofing material 1 having the falling portion 1a to which the elastic metal member 3 having the folded portion 3a is attached is fixed to the fixing metal member 5.
And from the outside of the roof so that it slides on the draining board 6
By pushing from the state shown in FIG. 2 to the state shown in FIG. 3, an elastic displacement shown by an arrow in FIG. 2 is generated in the folded part 3 a, and based on the elastic displacement, the folded part 3 a
It is possible to cause the locking portion 5a to get over.
Then, based on the overcoming, the folded portion 3a is turned into the locking portion 5
a, the metal roofing material 1 can be easily attached and fixed to the ground A. At this time, the seal portion 3b elastically contacts the locking portion 5a,
The space between the mounting space S and the bottomed portion U is sealed (see FIG. 5). In addition, since the metal roofing material 1 is fixedly attached to the ground A only by locking with the locking portion 5a in a state where the metal roofing material 1 is placed on the fixing bracket 5 and the draining plate 6, The permissible dimensional error at the time of attaching the metal roofing material 1 is such that accommodation occurs in the roof inclination direction. In addition, since the elastic fitting 3 is detachably attached to the falling portion 1a with the screw 4 operable from the outside of the roof, after all the metal roofing materials 1 are once attached to the ground A, a part of the elastic fitting 3 is partially removed. Even when a failure occurs in the solar cell or its connection part and it becomes necessary to partially remove the metal roofing material 1 corresponding to the failure occurrence part, by removing the screw 4 from the outside of the roof as shown in FIG. By releasing the locking state by the locking portion 5a, the part of the metal roofing material 1 can be easily removed as shown by a white arrow in FIG.

Next, another embodiment will be described. <1> When the elastic fitting 3 is attached to the falling part 1a with the screw 4, the falling part 1a and the elastic fitting 3
Instead of opening a pilot hole, open a screw insertion hole,
The screw 4 inserted into the screw insertion hole can be screwed and attached to a nut (not shown) arranged on the back side of the elastic fitting 3. <2> The screw 4 may be a bolt. <3> Although the displacement portion is formed using the elastic fitting 3 separate from the substrate 1A of the metal roofing material 1, the displacement portion is formed integrally with the falling portion of the substrate 1A. Any of these forms is generally referred to as a displacement section. <4> Further, the folded portion 3a provided in the displacement portion does not need to be provided over the entire width of the metal roofing material 1 in the width direction, and a plurality of folded portions 3a are formed in the displacement portion. It is desirable that the metal roofing materials 1 be juxtaposed in the width direction. With this configuration, even if the water droplets reach each of the folded portions 3a, the water droplets that have entered easily flow in one of the width directions and easily fall on the roof surface, so that the water droplets accumulate in the folded portions 3a. Things are hard to happen. Further, it is desirable that the folded portions 3a are juxtaposed at equal intervals in the width direction, and by juxtaposing them at equal intervals, the metal roofing material 1 can be mounted in a well-balanced manner, and it is possible to prevent rattling.
