Lightweight, elevated metal structure with a support system for integrating photovoltaic panels for a waterproofed roof terrace

Abstract

The invention is a lightweight metal structure, raised above a waterproofed roof terrace, designed to support a photovoltaic panel integration system. It involves creating a metal structure using cold-rolled galvanized profiles, directly attached to the building's framework by posts that pass through the waterproofing membrane. This structure is designed to accommodate a standard photovoltaic panel integration system, such as those found on carport-type installations.This system will preserve the existing waterproofing (no total removal, but just spot penetrations), partially protect it over time, provide shade on the roof to limit the impact of solar radiation in summer, allow better ventilation of the photovoltaic panels and therefore a higher yield than if they were attached directly to the roof and finally allow the installation of bifacial photovoltaic panels which would benefit from the radiation reflected by the roof.

Description

Title of the invention: Lightweight and raised metal structure with a support for a photovoltaic panel integration system for a waterproof flat roof. Technical field

[0001] The field of the present invention lies in the types of supports allowing the reception of photovoltaic panel integration systems on industrial roofs of the multi-layer waterproofing type called flat roofs and so-called inaccessible roofs. The state of the prior art

[0002] Photovoltaic panel integration systems for industrial roofs with multi-layer waterproofing require certain characteristics of the waterproofing complex in order to be installed properly (load-bearing capacity of the support tray with additional load, class C insulation, reinforced membrane, etc.). However, most of the time, the existing waterproofing complex has not been planned as with all the related constraints to receive these photovoltaic panel integration systems. Thus, it is often necessary to replace all or part of the complex (Membrane, insulation, see support tray) to meet the technical requirements of the existing systems, which is economically and ecologically detrimental. Existing systems also require the panels to be installed in contact with the waterproofing complex, which does not allow good ventilation of the lower face and therefore a lower efficiency of the installation due to overheating of the panels. Description of the invention

[0003] The device according to the invention therefore proposes, to overcome the drawbacks of other existing systems, to create a supporting metal structure in galvanized cold profile, raised above the existing waterproofing (1) (more than 80cm), taken up directly on the frame of the building (2) by tubular posts (6) crossing the waterproofing complex (1) and sleeved on suitable anchors (7). Supporting crosspieces (4) (in galvanized cold profile) will be supported by the posts (6) in the same plane as the main structure of the building. A jibe (5) (also in galvanized cold profile) running perpendicular to the crosspieces (4) will be supported by the latter and connected by means of samples. This structure is intended to receive a standard integration system of photovoltaic panels (3) that can be found on shade-type installations. Figure presentation

[0005] Metal anchor supports (7) are installed on the main structure of the building (2) on the underside of the waterproofing complex (1). The complex is drilled at the anchors and to the size of the through posts (6) to sleeve the latter onto the metal anchors (7). The drilling and the posts (6) are then waterproofed by upstands compatible with the nature of the membrane. The cold-profile crosspieces (4) are bolted to the posts (6) then the continuous purlins (5) are bolted onto the crosspieces (4) by means of samples (8). Finally, the photovoltaic panel integration system (3) is installed perpendicular to the purlins (5) to drain rainwater. Advantages of the invention

[0006] This installation will allow: - to safeguard the existing waterproofing (1) (no overall removal, but just specific crossings) - to partially protect it over time (bad weather, UV, etc.) - to provide shade on the roof and limit the impact of solar radiation in summer - to allow better ventilation of the photovoltaic panels (3) and therefore a higher yield than if they were placed directly on the roof like current systems - to be able to consider the installation of bifacial photovoltaic panels which would benefit from the radiation reflected by the roof. Potential industrial applications

[0007] Thus our concept is intended to be economically (better yield of photovoltaic panels) and ecologically (less waste and carbon impact in the case of an existing building) more efficient for equipping so-called inaccessible roof terraces with a photovoltaic installation.

[0008] It will allow the industrial roofs to be equipped with photovoltaic panels, including The cover is of the inaccessible flat roof type, without having to replace all or part of the existing waterproofing complex.
