Description

      The present invention is a support device for photovoltaic power generation panel mounts on tiled roofs. The device can be manufactured and installed in a simple manner, rain leakage does not occur after the installation of the photovoltaic power generation panel, and it can handle heavy wind and snow loads. It is a technology that combines the conventional technology with consideration of the fact that it has sufficient strength and the maintenance of roof tiles is reduced.

      As for the technology to drill two holes in one existing or new roof tile, the sand blasting method using compressed air or the small diameter Kowa removal method using the motor rotating shaft is adopted. Depending on the hardness, the method is properly used.

      For the lower mount hardware, the main body is located in the lower surface of the roof of the roof tile and the small space of the field plate. The structure is provided with rising walls on the base frame base plate and the two bolts, thereby enabling the distribution of the concentrated load applied to the bolts of the frame hardware. As a result, it has a shape that can handle a heavy load of wind and snow.

      The structure in which two mounting bracket bolts are installed at the peak of the first tile and the second tile of the same structure is installed at the adjacent position of the tile is combined with the peaks of the left and right tiles. Four point support is obtained. The four points of the long span support provide the strength and stability required for installing the upper base plate.

      A conventional tile roof solar power panel is constructed by replacing the old tile with a dedicated metal support tile. Since the structure of the metallic support tile is provided with facilities such as an opening, a protruding structure is located in the valley portion of the tile. For this reason, it is an obstacle to the location of the tiles.

      The method of installing bolts at the peak of the tile is a method of opening before the tile quenching and quenching after that. Therefore, the 1-hole method or the notch method is common. Before the tile quenching, the opening has a large error also in the position size of the hole, and there is a difficulty in quick construction.

      A three-layer structure combining a roof rafter, a field plate, and a reinforcing plate is a structure generally adopted as a bottom structure of a supporting tile. The fixing method is a method of fixing two roof rafters, a field plate and a reinforcing plate with screws or bolts and nuts.

      The shape of the support hardware positioned between the photovoltaic power generation panel mount and the reinforcing plate has a characteristic shape by adding various ideas to the shape considering the mounting load, waterproof performance and construction possibility. The document is

      In the support system of the photovoltaic power generation panel mount on the tile roof, the conventional system generally replaces the old tile with a dedicated support tile. The structure of the supporting tile is that the protrusion structure is located in the valley portion of the tile by providing equipment such as an opening. As a result, the protruding structure is an obstacle to the flow of water flowing through the valley of the roof tile, and there are problems that cleaning management is difficult after installing the photovoltaic power generation panel.

      When installing the mounting hardware bolts on the roof of the roof tile, a method is provided in which a hole is formed in the roof tile before quenching. However, it is difficult to secure a stable expected dimension after quenching and it takes a long time to manufacture. .

      When one hole of the support base hardware bolt is installed in the peak portion of the conventional roof tile, the strength of the support base hardware is insufficient with respect to a heavy load of wind and snow.

      The mounting position of the bolts of the support base hardware that drills two holes in the peak portion of the tile according to (Claim 2) is not the position of the valley portion of the tile but the position of the peak portion of the tile. It is characterized by solving the problem that hinders the running water in the valley of the tile.

      There are two methods of drilling work for drilling two holes in the roof of the tile. Part 1 is pasting a rubber sheet with an accurate hole position cut in advance on the tile, and then sandblasting with compressed air. It is to perform spray drilling construction. The rubber sheet affixed to the tile surface according to claim 2 is used as a tile reinforcement and a waterproof sheet after the fact.

      As the drilling method 2, the roof tile is fixed with a jig and then drilled with a wet diamond core punched cutter drill. The two methods of drilling work are selected according to the hardness of the roof tile.

      The roof tiles are installed in the two holes of the roof of the roof tiles through the bolts of the mounting hardware. The processing method of the strength reduction part by drilling in the vicinity of the tile hole which becomes the subsequent process is to reinforce the peak part of the tile with a waterproof sheet, to install the stretchable caulking waterproof in the gap between the hole and the bolt, and the caulking A waterproof sheet for secondary reinforcement is additionally applied to the waterproof upper surface.

      The structure of the mount hardware according to (Claim 1) is composed of a base plate, a wall, and two bolts, and is an integral structure by welding or the like. The mounting bracket is constructed at a position using a small space between the bottom surface of the roof tile and the top surface of the reinforcing plate, and the mounting bracket has a feature that the wall corresponding to the load in the horizontal and vertical directions suppresses the bending of the bolt.

      The upper frame base plate described in claim 3 is a metal plate that receives the frame that works between the metal frame of the photovoltaic power generation panel and the frame metal bolts below the roof tile. The upper frame base plate has a structure that obtains four-point support from two pieces of left and right adjacent roof tiles. This structure is characterized in that there is no hindrance to running water in the tile valley and that a stable structure is provided by a long span structure that forms a fulcrum at the peak position of the two tiles.

      The reinforcing plate installed on the top of the field plate is structured to fix two or more screws to three or more rafters. This is a structure that secures stability and high strength because it is increased from the conventional two rafter stops to at least three stops.

      The content of (Claims 1, 2, and 3) is proposed as a solar power generation panel installation stand support apparatus of a tile roof. And the item of the claim of this invention can be used individually or as an aggregate combined with the prior art. The listed hardware, board and waterproof sheet are not intended to fix the material, but to ask the characteristics of the required quality.

      The structure of the lower mount metal object described in (Claim 1) is large in that a large load is applied to the metal frame of the photovoltaic power generation panel mounted in the flowing direction of rainwater, so that two bolts are arranged in tandem. It is a structure that receives snow load.

      Two bolts of the lower mount bracket are constructed with a wall between the base plate, and the wall and the base plate are integrated with the two bolts to suppress the bending load applied to the bolt, and the strength of the entire lower mount bracket Ensure safety.

      According to (Claim 2), mechanically drilling two holes at the peak position of the tile in use or a new tile, and a waterproof sheet for reinforcing the tile at the peak position of the tile and for improving waterproofness is attached. This means that it is easy to adapt to the various conditions at the site.Therefore, it is possible to construct a small variety of old roof tiles without producing a large number of roof tiles exclusively for support at the factory. It is possible to respond to the type on site.
