However, the width of the roof field varies depending on the size and design of the house, and the module roofing materials 4 and 5 containing the solar cells cannot be cut off.
Utilizing the difference of one daylighting plate 48 with the module roofing material 5 of the above, that is, the width of 105 mm, the number of the first and second module roofing materials 4 and 5 should be selected in parallel according to the field width. Must.

FIG. 20 and FIG. 2 show concrete construction widths.
As shown in FIG. 1, the waterproof wall 16 of the waterproof plate 7, the first and second waterproof
When the vertical support legs 53 and the vertical walls 50 of the vertical rails 44 of the module roofing materials 4 and 5 are located at the central portions of the lower width adjusting portion 14, the intermediate width adjusting portion 24 and the upper width adjusting portion 32, respectively, The width D of the adjustment part is 11.5 mm, the distance W between the upper left and right width adjustment parts 32 is 29 mm, and the width E of the frame 47 is 18.5.
mm, the distance between the centers of the connecting members 2 and 3, that is, the standard construction width A per row is 606 mm and the construction width L in the case of the first module roofing material 4 having the construction width L of 530 mm.
Is 711 mm for the second module roofing material 5 of 635 mm
mm.

Next, an example of the correspondence between the combination of the first and second module roofing materials 4 and 5 and the field width U (see FIG. 22) will be described. When six first module roofing materials 4 each having a standard construction width A of 606 mm are arranged in parallel, an applicable field width U is 3636 mm, and the first module roofing material 4 is 5
When two sheets and one second module roofing material 5 having a standard construction width A of 635 mm are arranged side by side, an applicable field ground width U is 3741 mm.
When four first module roofing materials 4 and two second module roofing materials 5 are arranged side by side, the applicable field ground width U
Is 3846 mm.

The waterproof wall 16 of the waterproof plate 7 and the vertical rail 44
The vertical support leg 53 and the vertical wall 50 each have a thickness of about 1.5 mm, and move in the lower width adjustment unit 14, the middle width adjustment unit 24, and the upper width adjustment unit 32 toward the center of the connection members 2 and 3. The possible width I is 5 mm, the width J that can be moved in the outer edge direction is 5 mm, and the width can be finely adjusted to plus or minus 10 mm per row at maximum, so that the width between the actual roof field width U and the total finishing width can be adjusted. The error in the plus or minus direction is less than half of 105 mm, which is the difference in width between the first module roofing material 4 and the second module roofing material 5, that is, 5
In the case of 2.5 mm or less, fine adjustment is made by adjusting the overlapping width of the connection members 2 and 3, the module roofing materials 4 and 5, and the engagement portion.

When the total finishing width is wider than the field width U, as shown in FIG. 23, the vertical supporting legs 53 and the vertical walls 50 of the vertical bar 44 are located near the center of the connecting members 2 and 3 and have a minus width. After adjustment, the minus construction width B is 596 mm for the first module roofing material 4 and 701 mm for the second module roofing material 5. When the total finishing width is narrower than the field width U, as shown in FIG. 24, the vertical support legs 53 and the vertical walls 50 of the vertical bar 44 are located near the outer edges of the connecting members 2 and 3, and have a plus width. After making adjustments, the plus construction width C is the first
The module roofing material 4 has a thickness of 616 mm, and the second module roofing material 5 has a length of 721 mm.

Therefore, when six modular roofing materials 4 and 5 are arranged in parallel, fine adjustment of 10 mm in the plus direction and 10 mm in the negative direction is possible for each row, and the fine adjustment width of the entire roof is 60 mm.
This is half of 105 mm, which is the difference between the width of the first module roofing material 4 and the second module roofing material 5,
Since it is larger than 2.5 mm, the first and second module roofing materials 4 and 5 are appropriately selected and combined, and the connection members 2 and
By performing the fine adjustment in the width adjustment unit 3, it is possible to cope with all field widths.

For example, when the field width U is 3981 mm,
When three first module roofing materials 4 and three second module roofing materials 5 are arranged side by side, the standard total finishing width is 39.
It becomes 51 mm, and the field width U becomes 30 mm wider. Therefore, 5 mm, which is obtained by dividing 30 mm by the number of parallels of the module roofing materials 4 and 5, is adjusted in a plus direction for each row, so that the width of the first module roofing material 4 is 611 mm and the second module roofing material 5 is installed. The width may be 716 mm, and the connection members 2 and 3 may be allocated.

When the field width is 3786 mm, the first
When four module roofing materials 4 and two second module roofing materials 5 are arranged in parallel, the standard total finishing width is 3846
mm, and the land width U becomes 60 mm narrower.
10mm obtained by dividing mm by the number of parallels 6 is adjusted in a minus direction for each row, and the construction width of the first module roofing material 4 is 596 mm,
The width of the second module roofing material 5 is set to 701 mm, and the connection members 2 and 3 are allocated.

Tables 1 to 5 show combinations of the first and second modular roofing materials 4 and 5 and the corresponding roof field widths.

[Table 5] According to Tables 1 to 5, the allowable field width when the first and second module roofing materials 4 and 5 are combined overlaps with the adjusted field widths in the upper and lower columns. Means that any combination of the first and second module roofing materials 4 and 5 can be applied to a roof having any field width.
If the number of rows is selected to be large, the lighting efficiency with respect to the roof area increases.

For example, in the case of a roof having a field width U of 9400 mm, even if 13 first module roofing materials 4 and two second module roofing materials 5 are combined, 12 first module roofing materials 4 will be used. And three second module roofing materials 5 may be combined, or 11 first module roofing materials 4 and four second module roofing materials 5 may be combined.
Increasing the number of the second module roof members 5 increases the number of rows of the daylighting plate unit 48, and increases power generation efficiency. This selection range increases as the field width increases, and the daylighting plate alone 48
Can be increased in number, and the ratio of the lighting area to the construction area can be increased.

Further, fine adjustment can be performed in the keraba portion in the same manner as in the intermediate width adjuster 24 and the upper width adjuster 32, and the rising wall 43 of the keraba member 6 can adjust the side width of the side connection member 3. As shown in FIG. 25, the width F of the side width adjusting portion 38 is 31.5 mm.
mm, the thickness of the rising wall 43 is about 1.5 mm, so the plus adjustment width M and the minus adjustment width N
Is 15 mm each, and the left and right sides can be finely adjusted in total by 30 mm in the plus direction and 30 mm in the minus direction. Further, the width M ′ from the standard position of the fluff member holding piece 36 of the lower side connecting member 33 to the water return protrusion 21 of the fluff member 6 is substantially equal to or slightly larger than the plus adjustment width M.

When the fine adjustment on the side is unnecessary, as shown in FIG.
Is located at the center of the side width adjusting portion 38 of the side connection member 3, and when the total finishing width is wider than the field width U, as shown in FIG. If the total finishing width is narrower than the field width U by sliding toward the negative side, as shown in FIG.
Is slid toward the outer edge of the side connection member 3 to perform a minus adjustment.

Accordingly, when the side width adjustment is performed, the allowable width of the minus adjustment field width and the plus adjustment field width of Tables 1 to 5 is increased by 30 mm each, and the daylighting plate is further utilized by using the side width adjustment. The number of columns of the single unit 48 can be increased.
Furthermore, when the roof width U is different between the eaves portion and the ridge portion or when a construction error occurs, these errors can be absorbed in the keraba portion within the range of the width F of the side width adjusting portion 38. , Making the final construction easy.

Further, the inner end of the frame 47 and the lighting plate unit 48
As described above, a connection interval of 5 mm is formed as described above, so that even if the module roofing members 4 and 5 are attached with a maximum negative adjustment, the connection with the outer end of the upper width adjusting portion 32 is possible. An interval K having a width of 12 mm is formed between the lighting plate unit 48 and the lighting plate unit 48.

In the case of the first module roofing material 4a of mm, it is 870 mm, and in the case of the second module roofing material 5a having the construction width L of 935 mm, it is 1025 mm.

First and second modular roofing materials 4a, 5
To give an example of the correspondence between the combination of a and the ground width U, if six first module roofing materials 4a are arranged in parallel, the total finishing width becomes 5220 mm, and six first module roofing materials 4a are arranged in parallel and the second When one module roofing material 5a is juxtaposed, the total finishing width becomes 6245 mm. When this total finishing width corresponds to the actual field width U, the vertical support 53 and the vertical wall 50 of the vertical rail 44 are each provided with an intermediate width adjusting portion 83.
It is located at the center of the upper width adjustment unit 32 and does not require fine adjustment.

As shown in FIGS. 32 and 33, the vertical support legs 53 and the vertical walls 50 of the vertical rail 44 are respectively about 1.
It has a thickness of 5 mm, and the width of the middle width adjustment portion 83 and the upper width adjustment portion 32 is 15.5 mm. Therefore, the width I that can be moved in the center direction of the connection members 22 and 23 is 7 mm and can be moved in the outer edge direction. The width J is 7 mm, and it can be finely adjusted to plus and minus by 14 mm per row at the maximum. If there is an error between the actual roof field width U and the total finishing width, the connecting member 2
Fine adjustment is made by adjusting the overlapping width of the engaging portion between the module roof members 2 and 23 and the module roof members 4a and 5a.

Further, as shown in FIG. 34, the width F of the side width adjusting section 86 is the same as that of the side width adjusting section 38 shown in FIG.
Since the plus adjustment width M and the minus adjustment width N at the edge portion are 15 mm, the left and right sides can be finely adjusted by 30 mm in the plus direction and 30 mm in the minus direction. When the total finishing width is wider than the field width U, fine adjustment is performed in the same manner as the intermediate width adjusting section 83 and the upper width adjusting section 32, and as shown in FIG. The vertical wall 50 is positioned near the center of the connecting members 22 and 23 to perform a minus width adjustment, and the minus construction width B is set to 856 mm by performing a minus width adjustment of 870 mm to 14 mm in the first module roofing material 4a.
1025mm to 14mm for the second modular roofing material 5a
By adjusting the minus width, it becomes 1011 mm. When the total finishing width is narrower than the field width U, as shown in FIG. 36, the vertical support 53 and the vertical wall 50 of the vertical bar 44 are located near the outer edges of the connecting members 22 and 23 and have a plus width. After the adjustment, the plus construction width C is set to 870 mm for the first module roofing material 4a and adjusted to 14 mm plus width to 884 mm, and to the second module roofing material 5a to 1025 mm and adjusted to 1425 plus width by 1039 mm.

For example, if the field width U is 5447 mm,
When five first module roofing materials 4a and one second module roofing material 5a are arranged in parallel, the standard total finishing width is 5375 mm, and the field width U is 72 mm wider.
Therefore, 12 mm, which is obtained by dividing 72 mm by the number 6 of the module roofing materials 4a and 5a in parallel, is plus-adjusted for each row, the working width of the first module roofing material 4a is 882 mm, and the construction of the second module roofing material 5a is The width may be 1037 mm, and the connection members 22 and 23 may be allocated.

When the field width U is 5488 mm, when four first module roof members 4a and two second module roof members 5a are arranged in parallel, the standard total finishing width is 5 mm.
530 mm, and the field width U becomes 42 mm narrower.
Therefore, 7 mm, which is obtained by dividing 42 mm by the number of parallel of the module roof materials 4a and 5a, is minus-adjusted for each row, so that the construction width of the first module roof material 4a is 863 mm and the construction width of the second module roof material 5a. Is set to 1018 mm, and the connection members 22 and 23 may be allocated.

[Table 9] Also in Tables 6 to 10, a plurality of combinations of the first module roofing material 4a and the second module roofing material 5a can be selected for a certain field width, however, the first embodiment described above is used. Similarly to the above, the number of rows of the lighting plate unit 48 is selected so as to increase, and the lighting efficiency is increased.

Also in this case, the number of rows of the daylighting plate unit 48 can be increased by fine adjustment as the field width becomes wider.
It is possible to increase the daylighting area. Further, when the module roof members 4a and 5a are attached with the maximum negative adjustment, the outer end of the upper width adjusting portion 32 and the
The distance K between the light-collecting plate 8 and the light-collecting plate 8 is 13 mm.

The width F of the side width adjusting portion 86 of the side connecting member main body 84 is equal to the side width adjusting portion 38 of the side lower connecting member 33.
Is equal to the width F of 31.5 mm, and the thickness of the rising wall 43 is about 1.5 mm.
And the negative adjustment width N is also 15 mm, respectively, and the total of both left and right sides is 30 mm in the plus direction and 30 mm in the minus direction.
mm can be finely adjusted, and when fine adjustment on the side portion is unnecessary, as shown in FIG. 31, the rising wall 43 of the keraba member 6 is located at the center of the side width adjustment portion 86, and the total finishing width 35 is larger than the field width U, as shown in FIG. 35, the rising wall 43 is slid toward the center of the side connection member 23 to perform a negative adjustment, and when the total finishing width is smaller than the field width U, As shown in FIG. 36, the rising wall 43 is slid toward the outer edge of the side connection member 23 to perform the negative adjustment.

The size of the daylighting plate unit 48, the number of the daylighting plate unit 48 in the module roofing material in parallel, the width of the width adjusting portion of the connecting member, and the like can be changed as appropriate.

Further, a single 100 mm square daylighting plate 4 having a narrow width
By using a module roofing material in which 8 rows are arranged in the width direction and a module roofing material in which 9 rows are arranged, and the roof width 1 is covered with two module roofing materials, the width adjustment is further facilitated.

According to the roofing device utilizing solar cells of the present invention, the number of first and second module roofing members having a different number of light-collecting plates in the width direction by an appropriate number is appropriately combined to adjust the width of the intermediate portion and the side portion connecting member. Since the first and second module roofing members are slidably engaged in the width direction and connected to the first and second module roofing members,
By changing the combination of the and the second modular roofing material, it is possible to cope with roofs having various widths of the field, and by changing the engagement depth between the width adjusting portion and the side edge of the roofing material, By making adjustments, it is possible to roof roofs of all widths using only standard roof materials,
There is no need to cut, cut, or solder the roofing material, which makes the construction extremely easy and significantly reduces costs.

Further, by changing the fine adjustment width, the number of parallel light-receiving plates can be increased, and the ratio of the light-receiving area to the roof area can be increased to increase the light-receiving efficiency.
