Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to an aluminum alloy buckle roof photovoltaic support installation structure. Background Technology

[0002] Amid the global energy transition, with the advancement of "dual-carbon" goals and a surge in demand for green electricity, the photovoltaic (PV) retrofitting of existing buildings has become a key path to increase the proportion of renewable energy. Commercial complexes, industrial plants, and public buildings that previously lacked pre-designed PV installation capabilities are now seeking efficient and compatible integrated PV solutions. Aluminum alloy single-panel roofing, with its lightweight, high strength, excellent corrosion resistance, convenient construction, and good architectural aesthetics, is widely used in various scenarios such as commercial complexes and public buildings.

[0003] Due to the special roof structure, traditional installation methods are difficult to apply directly. Targeted design is needed for the installation of photovoltaic brackets on aluminum alloy single-panel roofs in order to create feasible conditions for the installation of photovoltaic modules. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an aluminum alloy buckle roof photovoltaic support installation structure.

[0005] This aluminum alloy roof photovoltaic support structure includes: a bottom beam, self-tapping screws, a light steel keel, and aluminum alloy panels; aluminum alloy panels are installed on the light steel keel, and the bottom beam is installed on the surface of the aluminum alloy panels; rubber gaskets are installed between adjacent aluminum alloy panels, and the rubber gaskets are fixed to the light steel keel by self-tapping screws that pass through the bottom beam, rubber gaskets, and light steel keel.

[0006] Preferably, rubber gaskets are fixed between the bottom beam and the aluminum alloy panel.

[0007] Preferably, the rubber gasket thickness is ≥5mm.

[0008] Preferably, sealant is applied between the rubber gasket and the light steel keel, and the head of the self-tapping screw located outside the bottom beam is covered with sealant.

[0009] Preferably, the self-tapping screw, rubber gasket, and sealant are on the same axis.

[0010] The beneficial effects of this utility model are:

[0011] 1) A rubber pad is provided between the bottom beam and the aluminum alloy panel of this utility model to prevent local stress concentration after the self-tapping screw is installed, which may cause deformation of the aluminum alloy panel.

[0012] 2) During the installation process, the bottom beam of this utility model is fixed to the roof using only self-tapping screws and sealant, with minimal interference to the roof. Even if the photovoltaic modules need to be removed later, it will not cause irreversible damage to the roof, which facilitates the subsequent adjustment of the building's functions.
