2. Description of the Related Art Conventionally, various types of metal roofs exist. In particular, as a fitting type metal roof,
There is a folded plate type or a tiled roof type having a cross section in which a chevron and a trough are continuous. In recent years, solar roofs have begun to spread from the viewpoint of energy saving and environmental protection. Among them, a vertical building plate constructed by mounting a solar power generation member on a vertically long main plate is often used as a construction member of an outer enclosure such as a roof (or wall). I have.

In such a metal roof, there is a flat type solar enclosure in addition to the folded plate type and the like. The flat-type solar enclosure has a roof surface formed by a flat roof plate with a solar power generation member and a flat cap material.

[0004]

However, as described above, the flat type roof with the solar power generating member does not have a suitable place for grounding the electric charge charged by the power generation of the solar power generating member. The construction of the ground by type was complicated.

[0005] Even when grounding is performed, it is necessary to perform several operations such as drilling through holes such as mounting bolts on a flat-type metal roof, which requires time and effort for mounting. This not only increases the burden on the workers, but also causes inconveniences such as infiltration of rainwater. Therefore, development of a ground structure in a flat solar enclosure that can easily and reliably perform grounding has been desired.

[0006]

The inventors of the present invention have conducted intensive studies in order to solve the above-mentioned problems, and as a result, have found that the present invention provides a flat solar architectural plate having fitting side portions on both sides in the width direction. A gutter and a cap material fitted to the opposed fitting sides of the adjacent flat building board, an elastic portion bent in a dogleg shape, and a horizontal plate supporting the elastic portion And a ground spring portion made of iron, steel plate or other conductive material. The ground spring portion has a tip portion formed so as to bite into the back surface of the flat solar building plate. The construction of the earth in the flat solar enclosure, which is provided with a roof, makes it possible to complete the construction of the ground simultaneously with the construction of the roof, making it extremely simple and reliable, and improving the construction efficiency. Markedly It improved, and sufficiently excellent mechanical strength is obtained by solving the above problems.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1A is a schematic front view showing a state where an earth spring portion is attached to a flat solar enclosure according to the first embodiment of the present invention. First, the flat solar architectural plate A has fitting sides 2 formed below both sides in the width direction of the main plate 1.

Next, as shown in FIG. 4 and the like, the cap material C is formed by bending a metal plate appropriately and is elongated in the longitudinal direction, and fitting leg pieces 4 and 4 are formed on both sides of the top 3 in the width direction. In addition, bent ends 4a, 4a are formed at the lower ends of the fitting leg pieces 4, 4. Specifically, the top portion 3 and the fitting leg pieces 4 and 4 are integrally formed by appropriately bending a metal plate, and the space between the top portion 3 and the fitting leg pieces 4 and 4 is substantially the same. It is folded back in an arc shape. Then, the flat solar building plates A,
A is fitted to the opposite fitting side portions 2
a, 2a and 4a, 4a are fitted.

Next, as shown in FIG.
As shown in FIG. 4, it is formed in a U-shaped cross section, and rising side portions 5b, 5b are formed on both sides in the width direction of the bottom portion 5a, as shown in FIG. Horizontal pieces 5c, 5c inward from the upper ends of both rising side portions 5b, 5b
Are formed. The gutter 5 is fixed directly to the base portion 9 or is fixed via fixing members 7, 7,... And fixing members 8 such as screws and bolts. The structure of the base 9 may be a structural material 9a made of a conductive material such as a lip channel steel, an H-shaped steel or an I-shaped steel, or the structural material 9a.
And a base material 9b such as a heat insulating plate. When the base portion 9 is composed of only the structural material 9a, the gutter 5 can be fixed by welding means.

As shown in FIGS. 1 to 3 and the like, the fixing member 7 is formed by bending a band plate to form pressing portions 7b, 7b at both longitudinal ends of a fixing plate portion 7a. is there. The fixing members 7, 7,... Are disposed between the gutters 5, 5,.
The two holding parts 7b, 7b hold and fix the horizontal pieces 5c, 5c on both sides in the width direction of the gutter 5, and
Are arranged and fixed on the base portion 9 (FIG. 2).
reference). When the fitting side portions 2 and 2 of the flat solar building plate A are fixed near both sides in the width direction of the gutter 5, the fitting side portions 2 and 2 are fixed to the holding portions 7 b and 7 b of the fixing member 7. 2 is fitted.

The flat solar building board A comprises a main board 1 and a coating film 10. On the surface of the main plate 1, a solar power generation member 1b is mounted. The solar power generation member 1b is a solar cell formed in a sheet shape. The solar power generation member 1b is sealed with an EVA (ethylene-vinyl acetate copolymer) resin or the like, and is mounted on a steel plate 1c made of iron or another conductive material with a coating 1a such as a fluororesin film. As a result, the durability of the solar power generation member 1b is enhanced (see FIG. 2 and the like). The back surface of the steel plate 1c is covered with a coating film 10 to prevent electric shock and oxidation.

Next, a description will be given of an earth spring portion D which may be provided so as to be engaged with the fixing plate 7 in the present invention (see FIGS. 1 to 5). The ground spring portion D includes an elastic portion 11 formed in a bent shape and a horizontal portion 12 as a horizontal plate supporting the elastic portion 11, and is formed of iron, a steel plate, or another conductive material. You. A tip 6 is formed at one end, and preferably, the tip 6 is formed in a sharp shape. That is, the flat solar building plate A
It is formed so as to bite into the back surface of. In order to function as a ground, the ground spring portion D is preferably locked on the fixed plate 8 with a screw or the like via a through hole 8a. However, it may be locked by welding, adhesive or the like.

In this state, when the main plate 1 (flat solar architectural plate A) is pressed downward, the sharp tip 6 of the earth spring D is applied to the coating applied to the back surface of the main plate 1. Break through (see FIG. 6A). As a result, the ground spring portion D is added to the steel plate 1c on the upper layer of the coating film.
As a result, the flat solar construction plate A and the ground spring portion D
Continuity with the terminal is ensured. Accordingly, the electric charge charged on the flat solar construction board A is satisfactorily grounded to the ground portion 9 made of a conductive material via the ground spring portion D. In addition, since the ground spring portion D has elasticity, it is possible to always keep the flat solar building plate A pushed up from below.

[0014]

EXAMPLE As shown in FIG. 6, the load when the main plate 1 (flat solar architectural plate A) was pressed downward until certain conditions were satisfied and the state of grounding were measured.
Specifically, the height of the earth spring portion D (distance from the body and the frame to the back of the flat solar building plate A)
However, the load from compression from 40 millimeters to 32 millimeters was measured three times.

As a result, the first load is 250 Newton (25.49 kgf), the second load is 250 Newton (25.49 kgf), the third load is 300 Newton (30.59 kgf), and the average is 266 Newton. (27.12 kgf). Here, when the continuity test was confirmed by the resistance value for the state of the grounding, it was confirmed that the grounding was completely performed with a relatively small load of 75 Newtons (7.65 kgf). Therefore, according to the ground structure of the flat solar enclosure of the present invention, the construction of the roof is completed and the construction of the ground is completed at the same time.

Here, in the present invention, a plurality (two) of the ground spring portions D, D are disclosed for one flat solar construction plate A (for example, see FIG. 1). However, the present invention is not limited to this, and as another modified example of the first embodiment, a structure in which one ground spring portion D is attached to one flat solar construction plate A [FIG.
(B)). This is because grounding is reliably performed even in this case, and a good antistatic effect can be obtained. Further, three or more earth springs D, D,... May be attached to one flat solar building plate A. For example, when the standard size of one flat solar building plate A is large, the ground spring portion D grounds from a plurality of locations.
This is because a better antistatic effect can be obtained.

[0017]

Function: A plurality of gutters 5, 5,... Are arranged and fixed in parallel on a base portion 9, and flat building plates A, A,. The gutter 5 is fixed near the upper sides of the gutter 5 on both sides in the width direction. Next, the cap member C is fitted and fixed between the fitting side portions 2 and 2 between the adjacent flat building boards A and A. Also,
The gutter 5 is fixed to the base portion 9 with a fixing member 7 and a fixing tool 8 (see FIG. 6). Alternatively, the gutter 5 may be performed by welding means.

[0018]

According to the first aspect of the present invention, there is provided a flat solar architectural plate A provided with fitting side portions 2 on both sides in the width direction;
A gutter 5 and a cap material C which are fitted to the opposed fitting sides 2 and 2 of the adjacent flat building plates A and A,
An elastic part 11 bent in a dogleg shape;
And a horizontal portion 12 as a horizontal plate for supporting
And a ground spring portion D made of iron, steel plate or other conductive material. The ground spring portion D is provided with a tip portion 6 formed so as to bite into the back surface of the flat solar construction plate A. First, the construction of the earth in the solar enclosure enables the construction of the roof to be completed at the same time as the construction of the roof, so that the construction can be performed very simply and reliably. Second, construction efficiency can be significantly improved. Third, a ground structure having sufficiently excellent mechanical strength can be obtained.

In detail, the flat solar construction plate A constructed as a roof by fitting the gutter 5 and the cap material C together with the gutter 5 and the cap material C disposes unnecessary electric charges generated from the solar power generation unit 1b to the earth spring unit D. Through the base material 9 formed of a metal or other conductive material via the base material, the ground can be taken.

In particular, the ground spring portion D is configured to include an elastic portion 11 bent in a dogleg shape and a horizontal portion 12 as a horizontal plate for supporting the elastic portion. When the solar building plate A is fitted with the gutter 5 and the cap material C, the back surface of the flat solar building plate A comes into contact with the tip 6 of the ground spring portion D. Then, at the time of complete fitting (at the time of completion of construction), the distal end portion 6 of the earth spring portion D penetrates the coating film 10 applied to the back surface of the flat solar building plate A, and Dig into 1c.

As a result, the steel plate 1c of the flat solar building plate A and the ground spring portion D are electrically connected to each other, so that the ground 9 can be grounded to the metallic base material 9 or the like. The construction of the ground can be completed reliably and satisfactorily simultaneously with the completion of the construction of the roof, and the construction of the ground in the flat solar enclosure can be performed very simply and reliably, which is an extremely excellent effect.

Further, as described above, since the construction of the roof can be completed reliably and satisfactorily simultaneously with the completion of the construction of the roof, the construction efficiency can be remarkably improved.
In addition, since the ground spring portion D has an elastic force toward the flat solar building plate A, even if the roof construction is completed for many years, the tip portion 6 always has the flat solar building plate. The state in which the steel sheet 1c of A is bitten can be maintained. As a result, there is an extremely excellent advantage that the ground state can always be maintained satisfactorily for many years, and also a state excellent in mechanical strength can be maintained.

Next, according to the second aspect of the present invention, in the first aspect, the ground structure in the flat solar enclosure having a sharp end portion 6 of the ground spring portion D is provided. In addition to the excellent effects and advantages of the present invention, the sharpened tip portion 6 allows the tip portion 6 to bite into the steel plate 1c of the flat solar building plate A more reliably. As a result, even if there is unevenness in the application of the coating film 10 on the back surface of the flat solar construction board A and there is a portion having an increased thickness, the ground can be reliably taken through the earth spring portion D. There are very good advantages.
