Now, as shown in FIGS. 2 and 3, since the lighting glass body B is not attached to the outer half of the side connection member A' in the transverse direction, the support groove 11 is attached to this side.
However, the side connection cover D' is not provided with a dripping prevention piece 24. A fitting protrusion 34 is formed in this outer half, and a fitting recess 35 into which the fitting protrusion 34 of the side connecting member A' fits is formed in the corresponding half of the side connecting member cover D'. form. In addition, the combination of the side connection member A' and the side connection member cover D' is such that the fitting protrusion 34 of the side connection member A' fits into the fitting recess 35 of the side connection member cover D', and the wind pressure is reduced. Form a reinforced structure. Further, the side connecting member has a symmetrical shape on the right side and on the left side.

Although not shown, the intermediate connecting member A is configured to be symmetrical in cross section, and each transverse half has the same structure as the inner half of the side connecting member A'.

Next, an outline of the assembly of the solar energy collection device will be explained. First, the square pipe 1 and the channel steel 2, which are integrally provided perpendicular to each other, are attached to a frame such as a steel frame, and the side connecting members A' are placed on both sides of the collection device, and the intermediate connecting member A is placed between them. As mentioned above, each of the connecting members A and A' has a connecting member mounting bracket 4 whose center part is inserted through the round hole, and a metal fitting 4 whose both ends are inserted through the elongated hole 15. , is fixed to the channel steel 2 so as to be able to absorb the thermal expansion.

Next, attach the lighting glass body fixing fittings P and the lower end engagement fittings 21 to each of the connecting members A and A' with the bolts 18,
20, the lower end cover G is engaged and attached to the engaging fitting 21, and the lower end cap E is fitted to the connecting members A, A' and the cover G, and then the mounting bracket 4 is attached. Tightly fix it to the bolt 5a with a nut (not shown). Then, the lighting glass bodies B ₁ to B ₃ are sequentially connected to the adjacent connecting members A and A' via the fixing fittings P, and the respective connecting member covers D and D' are opened at the top of the connecting members A and A'. the part. Lighting glass bodies connected in this way
_B1 to _B3 form a dustproof and waterproof structure, and in the event that water leaks from the outside, it will be drained to the outside through the drain grooves 12 of the connecting members A and A' and the water hole (not shown) of the lower end cap E. It is designed to be expelled.

Further, the intermediate connecting member cover D and the upper end cover I are each fixed to the connecting member A with bolts and nuts (not shown), and the adjacent covers I fixed in this manner are
The upper end cover connection member T is fitted and covered at the joint portion of the upper end cover. Next, the decorative cover L is fitted and attached to the side connecting member A', the side connecting member cover D', and the intermediate connecting member A adjacent thereto from the side of the side connecting member A',
Finally, the joint between the covers I and L is covered with a decorative cover connecting member T'.

Effects of the Invention As described above, the side connection member of the solar energy collecting device has a support groove provided inside the main body, and a drainage groove and a glass body fixing support groove are sequentially formed only on one side of the support groove. Since the support groove has a fixing hole and a long hole, it is suitable for use as a structural member for both side edges of the collection device, as well as for assembling other components of the device such as the lighting glass body and the lower end cover. Even if water leaks from the outside of the device, it can be drained from the drain groove.Thermal expansion of the side connection member is done equally upward and downward, with the base point approximately in the center, so that water leaks from the outside of the device. This greatly contributes to the provision of a solar energy collection device that has a small relative displacement with respect to the surface of the solar cell, can absorb thermal expansion well, has a windproof structure, and can withstand use under various environments.
