A tile for attaching a solar battery module to the roof of a house comprises a substantially rectangular plate-like tile body. The upper surface of the tile body has a plurality of projecting portions and depressed portions alternately extending over the entire length of the tile in a direction of inclination of the roof. The upper surface of the tile body also has a recess for receiving the solar battery module. The recess has a bottom portion to be brought into contact with the reverse surface of the solar battery module. The recess also has a plurality of stop portions to be brought into contact with edge portions of the solar battery module to hold them.

A roofing tile for performing solar-light power generation includes a roofing tile main body set tilted on a roof, and a photovoltaic module fixed to the main body. The roofing tile main body has a recess open upward. The photovoltaic module is stored and fixed in the recess. The roofing tile main body has an eaves-side edge portion. This edge portion has a plurality of drain ditches. Each drain ditch crosses the upper portion of the eaves-side edge portion and communicates with the recess. The level of the bottom surface of each drain ditch is equal to or lower than that of the bottom surface of the recess. With this construction, rainwater that has entered the recess is discharged through the drain ditches. Rainwater is drained by running the rainwater downward on the upper surface side of the eaves-side edge portion along the tilt direction of the roofing tile.
摘要:
The upper surface of a tile body for use as a roofing material for a building is provided with a depression that holds therein a photovoltaic cell module having a function to convert solar energy into electrical energy. An adhesive is applied to the whole or part of the base of the depression, and the photovoltaic cell module, which has a terminal box on its lower surface, is fixed to the base of the depression by adhesive bonding.

A crane has an elevation structure foldable at its intermediate portion, a rope extended along the structure and a rope support for supporting the rope. When the structure is folded and elevated, the rope support is moved to and held at a position near the point of folding of the structure. After the completion of straightening of the structure, the rope support is held at a position adjacent to the extreme end of the structure. A rope supporting apparatus for realizing this method includes an arrangement for mounting the rope support for movement along the structure, and a shifting driving mechanism mounted on the rope support and adapted to drive the rope support along the length of the structure.
