A general-purpose profile roof structure for photovoltaic sunshine houses that can be wired and waterproof

Abstract

The invention relates to a photovoltaic sunlight room universal type profile roof structure. Second square steels are welded on the left side and the right side of the upper end face of each lengthways girder, and a first interval which contains series cables is left between the two second square steels on each lengthways girder. First square steels are welded on the left side and the right side of the upper end face of each cross beam, and a second interval is left between the two first square steels on each cross beam. Each two square steels located on each lengthways girder lengthways cut off all the first square steels, and cut-off portions are connected through welding. All the first square steels and the second square steels form a latticed bearing frame matched with double glass photovoltaic modules. The series cables are buried in the first intervals, and the upper portions of the series cables are filled with foam cushions. Positions, located the below double glass photovoltaic modules, in the first intervals and the second intervals, are filled with first layer waterproof silicone sealant, and positions located above the first intervals and the second intervals and between each two double glass photovoltaic modules are filled with second layer waterproof silicone sealant. The photovoltaic sunlight room universal type profile roof structure uses universal profiles, andhas the advantages of being reliable in water prevention performance, good in invisibility of wire cable arrangement and the like.

Description

technical field [0001] The invention belongs to the field of photovoltaic systems, and relates to a general-purpose profile roof structure for a photovoltaic sunlight room that can be wired and waterproof. Background technique [0002] Photovoltaic sun room is a non-traditional low-carbon building built with double-glass photovoltaic modules and metal frames. When the double-glass photovoltaic module joint is used for a long time, there will be water leakage. In addition, considering the aesthetics of the sun room, it is necessary to conceal the serial cables between the double-glass photovoltaic modules. [0003] Chinese patent CN109217794A discloses an inner longitudinal waterproof structure for a photovoltaic waterproof system. This structure aims to solve the problem of water leakage, and the serial cables cannot be concealed. In addition, there are also problems of complex structure and special profiles, so the project adaptability is poor, and it is difficult to use ...
