In areas where the upper tile bar half body 14 becomes an obstruction, only that portion of the upper tile bar half body 14 is removed, and a piping space is formed on the lower tile bar half body 13.

The waste boards 4 laid on the field board 2 have rising parts 4 on both side edges.
a, and this rising portion 4a enters inside the inverted ridge 15 of the lower tile bar half body 13.

The heat insulating material 5 is arranged on the waste board 4 at the bottom between the adjacent tile bars 3.3 without any covering, but as shown in Japanese Patent Application Laid-Open No. 15538/1983, the heat insulating material 5 is made of aluminum. It may be replaced with a so-called metal roofing material covered with a metal plate such as a plate (in this case, the tile rod 3 may also serve as a connecting member for this metal roofing material).

The tile rod 3 is formed such that the interval between the left and right side walls 22, 22 of the upper tile rod half body 14 is smaller than the width of the lower tile rod half body 130, and the heat collection area where the heat collection plate 6 is installed is made as large as possible. It has been made possible.

and the mounting leg portion 37 and the glass vertical frame restraining leg portion 38.
A packing 40 made of an elastic body such as a sponge body is fitted into the upper space between the two and filled in the upper space.

The left and right vertical frames 41 of the framed cover glass 7 are held between the horizontal outward projections 28 of the tile rods and the restraining legs 38 of the tile rod cover 35.

The vertical frame 41 is made of an extruded aluminum material with a street-shaped cross section, and has a pair of upper and lower white edges 42 and 43 facing each other at its outer end, and an opening-like mounting section on the outer surface. A member fitting groove 44 is formed, and a rising wall 45 is provided on the upper surface of the outer end to be approximately at the same height as the side wall 22 of the tile bar 3, and this is inserted into the backing 40 in the tile bar cover 35. ing.

Further, at the inner end, a pair of upper and lower folded portions 46, 46 in the shape of a cutout circuit are provided in an opposing manner, and both side edges of the transparent cover glass 70 are placed between these folded portions. They are watertightly fitted through a gasket 47 having a substantially U-shaped cross section.

Furthermore, a support leg 48 is protruded from the middle of the width of the lower surface of the vertical frame 41, and this supports the upper protrusion 29 of the horizontal outer protrusion 28 of the earth tile bar half body 14. and 30.

Although the weight of the cover glass 7 can be supported by the above-mentioned mounting method alone, it is not possible to completely prevent the cover glass 7 from lifting up due to the influence of wind pressure or the like.

Therefore, the vertical frame 41 is further integrally connected to the tile bar 3 via a plurality of attachment members 49 provided at predetermined intervals as shown in FIGS. 4 and 5.

The mounting member 49 includes a mounting plate portion 51 that is fitted into the groove 31 and fixed to the back wall thereof with screws 50, and a mounting plate portion 51 that has a T-shaped cross section on the road side that rises from the center and projects outward. Joining part 52
The fitting portion 52 fits into the fitting groove 4 of the vertical frame 41.
4 is slidably fitted.

In order to easily attach the vertical frame 41 as described above using the attachment members 49 on site, attachment members 49 are provided at predetermined intervals on the lower outer horizontal portion of the vertical frame 41, that is, on the lower wall of the fitting groove 44.
A notch 44a that is slightly longer than the fitting part 52 is formed, and after fitting the fitting part 52 into the vertical frame 41 through the notch 44a, by slightly shifting the vertical frame 41 downward. , the fitting portion 52 can be fitted into the groove 44.

Note that, although not shown in detail, horizontal frames 53 are attached to the upper and lower edges of the cover glass 7 so that they can be fitted and connected to each other, and this is connected to the horizontal outer protrusion 28 of the upper tile bar half body 14. It is placed on and supported on the upper flange 29°30 of.

In the map, 54 is a cover of a side chamber in which the vertical pipe part of the drain pipe 12 is housed, 55 is a tile rod filler that blocks the outer surface of the tile rod 3 on the opposite side to the side chamber, and 56 is the inlet pipe 11 and the drain pipe. 12 is a cover of the front chamber in which the lower horizontal pipe section is housed, 57 is an eave partition plate, 58 is a partition plate between the front chamber and the heat collecting section, and 59 is a ridge wrapping plate.

In the above, the assembly of the 3 tile rod parts is as follows: First, the lower tile rod half 13 is fixed on the roofing board 2 with nails 18, and then the upper tile rod half 14 is fitted thereon and fixed together. After the vertical frame 41 of the cover glass 7 is assembled and attached to the attachment member 49, the tile rod cover 35 is finally placed on the cover glass 7 to complete the assembly.

This invention is based on the above-mentioned structure, and the lower tile bar half 1 has a main body portion of the tile bar 3 having a tile bar cover 35 on the upper surface and has a substantially U-shaped cross section.
3, and an upper tile bar half body 14 that can be fitted and tightly coupled thereto.
Since it is divided into two parts, upper and lower, when the entire tile rod main body is integrally molded to have a substantially U-shaped cross section as in the past, the installation and fixation with the nails 18 is done on the left and right side walls. Since it has to be done through the narrow space between the two, special tools and nails are required, which makes the workability somewhat difficult.However, in accordance with the present invention, only the lower half of the tile bar 13 with a low height is used. After attaching with nails 18, the upper tile bar half body 14 is fitted from above, thereby fixing the main body part of the tile bar 3 having the desired height on the roofing board 2. The tile rod 3 can be easily installed on the rafters 19,
Work efficiency can be improved.

In addition, since the upper tile bar half body 14 does not need to have a wide gap between its left and right side walls 22, 22 as a space for nailing work, this can be made as narrow as possible, and the height can be adjusted arbitrarily. Since the heat collecting plate 6 can be installed in a relatively large heat collecting area, and the heat insulating material 5 is made thick enough, it is possible to achieve an efficient heat collection with excellent heat insulation effect. A hot part can be formed.

Furthermore, the upper tile bar half body 14 has a relatively large cross section.
Since this can be formed into any hollow shape having one or more pairs of connecting walls 24, 25 above and below the left and right side walls 22, 222, it is possible to achieve good dimensional accuracy only by extrusion molding. There is no need for the troublesome manufacturing work of removing unnecessary parts from a tile bar that is once extruded into a hollow shape to achieve dimensional accuracy to obtain a tile bar with the desired U-shaped cross section.

Furthermore, in areas that obstruct piping such as the inlet pipe 11 and the drain pipe 12, only the lower half tile bar 13 is installed and the upper half tile bar 14 is removed to create piping space. Therefore, there is no need to cut out the main body of the tile rod itself for piping as in the past.
It is easy to manufacture and has good workability.
