Abstract

The subject matter of the utility model is a system for assembling a supporting structure, especially for photovoltaic panels, characterized in that the supporting structure consists of vertical supports for photovoltaic panels and of longitudinal connecting sections whose cross-section resembles the shape of an inverted "U", which sections are arranged between the supports. The connecting sections are detachably connected to the supports by placing the ends of the sections in the sockets of the supports and then joining them together using a joining piece, preferably a sheet metal screw. The connecting section has holes near both of its ends, which holes correspond to the side holes in the supports, so that after the end of the connecting section has been placed in the socket of the support it is possible to join them together preferably by means of a sheet metal screw. The joining piece is put through a rectangular washer, which is adapted to the shape of the side hole in the support. The connecting sections reinforce the stability of the supporting structure while also setting precise distances between the supports and further rows of photovoltaic panels.

Description

System for assembling a supporting structure, especially for photovoltaic panels
The subject matter of the utility model is a system for assembling a supporting structure, especially for photovoltaic panels.
Previously known systems for assembling supporting structures designed especially for photovoltaic panels are made of large elements (ready-made systems of frames and supports), which makes their transport and assembly difficult due to their size and weight, or of a high number of small elements, the connecting of which is very time-consuming. These features become particularly evident in the case of the so-called solar farms, where hundreds of modules with photovoltaic panels are used.
Utility model application No. CN210899008U reveals a solution in the form of a supporting frame or a series of supporting frames, which are permanently bonded to concrete bases ensuring stability of the construction. Solutions of this kind are extremely cumbersome during both transport and assembly. Individual frames constitute a monolithic construction of considerable dimensions, and the concrete bases, due to their weight, additionally hinder assembly and transport.
Invention application No. US2013153520 reveals a solution concerning a system for the manufacturing of supporting bases for photovoltaic panels. The solution uses metal spokes connected in such a way that they form triangular frames, further connected to each other by means of appropriate sections. However, assembly of this kind of structure is very time-consuming due to the very high number of elements, especially in the case of connecting many photovoltaic panels to create the so-called solar farms. What is more, such a construction needs to be permanently bonded to the ground in order to ensure its stability.
The system for assembling a supporting structure, especially for photovoltaic panels, of the utility model, is characterized in that the supporting structure consists of vertical supports for photovoltaic panels and of longitudinal connecting sections whose crosssection resembles the shape of an inverted “U”, which sections are arranged between the supports. The connecting sections are detachably connected to the supports by placing the ends of the sections in the sockets of the supports and then joining them together using a joining piece, preferably a sheet metal screw. The connecting section has holes near both of its ends, which holes correspond to the side holes in the supports, so that after the end of the connecting section has been placed in the socket of the support it is possible to join them together preferably by means of a sheet metal screw. The joining piece is put through a rectangular washer, which is adapted to the shape of the side hole in the support. The connecting sections reinforce the stability of the supporting structure while also setting precise distances between the supports and further rows of photovoltaic panels.
The system for assembling a supporting structure, especially for photovoltaic panels, of the utility model, ensures fast and precise assembly of even very extensive photovoltaic installations, which then translates into lower costs of installation. At the same time, use of detachable elements of the supporting structure that get connected to each other only during the assembly of photovoltaic panels ensures more convenient transport thereof.
The subject matter of the utility model is presented in the drawing, where fig. 1 shows the connecting section as well as the low support and the high support, before they are joined together, fig. 2 shows the low support and the high support joined with the connecting section, fig. 3 shows the low support and the manner of joining it with the connecting section, and fig. 4 shows an embodiment of the supporting structure of the utility model in a variant for eight photovoltaic panels in two rows.
The individual elements marked in the drawing are as follows:
1 - connecting section,
2 - high support,
3 - low support,
4 - hole in the connecting section,
5 - washer,
6 - joining piece,
7 - side hole in a support,
8 - socket of a support.
The system for assembling a supporting structure, especially for photovoltaic panels, consists of longitudinal connecting sections 1 whose cross-section resembles the shape of an inverted “U” and which near both of their ends have holes 4 intended for screwing in a joining piece 6, preferably a sheet metal screw. The first end of the connecting section 1 is placed in the socket 8 of the high support 2, and the second end of the connecting section 1 is placed in the socket 8 of the low support 3, wherein the sockets 8 of the high support and of the low support correspond in shape to the cross-section of the connecting sections. After the ends of the connecting sections have been placed in the sockets 8, the connecting sections are fastened by means of joining pieces 6, preferably sheet metal screws, and washers 5. The washers 5 have a shape that matches the side holes 7 in the supports, preferably rectangular. A single connecting section 1 with a high support 2 and a low support 3, when joined together, form a single supporting structure for a photovoltaic panel, wherein a single panel is supported on two supporting structures.
As shown in fig. 4, the supporting structures hold photovoltaic panels arranged in rows, with any number of photovoltaic panels in each row, wherein the connecting sections 1 additionally set precise distances between further rows of photovoltaic panels thus ensuring their optimal arrangement but also stabilizing the entire construction.
