Integrated-type steel structure roof photovoltaic system

Abstract

The invention relates to an integrated-type steel structure roof photovoltaic system. The integrated-type steel structure roof photovoltaic system comprises main beams, secondary beams, pieces of angle steel, purlines, supporting blocks, electric weld pieces, assembly frames, pressing blocks, pressing strips, sealants, waterproof adhesive tapes, color steel tiles, lateral cover plates and photovoltaic plates. The secondary beams are vertically erected on the two sides of the main beams correspondingly, the main beams are each in a U shape, and the two sides of the main beams are provided withmain beam shoulders, wherein the directions of the main beam shoulders are inward. Semicircular notches are pressed in the main beam shoulders, and the pieces of angle steel are welded to the outer sides of the bottoms of the main beams correspondingly and connected with the purlines through first screws. The integrated-type steel structure roof photovoltaic system has the beneficial effects thatthe main beams with the U-shaped sections, the inverted-T-shaped supporting blocks and certain compression components are adopted to constitute the integral mounting system, on-site construction is easy and convenient, materials are saved, and the roof water discharge is also greatly increased; and compared with a traditional building photovoltaic integrated system, the main beams are fixed to thepurlines through the pieces of angle steel on the outer side, inner cavities of the main beams do not need to be punched through, and water in the main beams is prevented from entering a building.

Description

technical field [0001] The invention belongs to the field of solar photovoltaic technology, and in particular relates to an integrated steel structure roof photovoltaic system. Background technique [0002] Distributed roof photovoltaic power plants have the advantages of not occupying land, not limited by photovoltaic indicators, and low cost, and have been widely used. To build a photovoltaic power station on a steel structure roof, the photovoltaic panel is often erected directly on the color steel tile, which is simple in construction and low in cost. However, the service life of conventional color steel tiles often does not meet the requirements of 25 years of photovoltaic power plant operation, or the roof color steel tiles have been corroded at the beginning of the construction of photovoltaic power plants, and the color steel tile roof needs to be replaced, which increases the investment cost of photovoltaic power plants and limits Distributed roof photovoltaic powe...

AI Technical Summary

Problems solved by technology

The disadvantage of this structure is that screws are used to penetrate the inner wall of the W-shaped bracket and connect with the roof purlins. During use, the water in the bracket will enter the building along the gap at the screw hole, resulting in water leakage.

In addition, during the 25-year operation period of the photovoltaic power station, the aging of the rubber block at the bottom will loosen the joints of the photovoltaic panels, causing the photovoltaic panels to slip
