AI Technical Summary

Technical Problem

In existing technologies, rainwater can easily seep into the roof from between two adjacent support components, affecting the waterproofing of photovoltaic buildings.

Method used

Design a roof structure in which the overlapping part of the support member fits and is fixedly connected to the second connecting part. The height of the overlapping part is higher than that of the photovoltaic module. Rainwater flows along both sides of the overlapping part to the photovoltaic module and is discharged. Combined with the design of the sealing connection and waterproof layer, the waterproof performance is enhanced.

Benefits of technology

It effectively prevents rainwater from seeping into the roof, improves the waterproofness and wind resistance of photovoltaic buildings, and enhances the overall performance of the roof structure.

Abstract

The application relates to a photovoltaic building and a roof structure thereof, the roof structure comprising a plurality of support pieces sequentially laid along a first direction, each support piece comprising a first connecting part, a supporting part and a second connecting part sequentially arranged along the first direction, the first connecting part being provided with an overlapping part at an end away from the supporting part, the supporting part being used for supporting a photovoltaic module, and the top surface of the overlapping part being higher than the height of the photovoltaic module; in the two adjacent support pieces, the overlapping part of one support piece overlaps the second connecting part of the other support piece, and the overlapping part and the second connecting part are fixedly connected. When raindrops fall on the overlapping position between the two adjacent support pieces, the raindrops can flow to the photovoltaic modules with lower height on both sides along the first direction along the top of the overlapping part, and then be discharged on the photovoltaic modules along the inclined direction YY' of the roof, so that the rainwater can be prevented from penetrating into the roof from the overlapping position of the two adjacent support pieces.
