Description

Technical Field

[0001] This utility model relates to photovoltaic power generation, and in particular to an overhead photovoltaic roof. Background Technology

[0002] In existing technologies, the installation methods for building roof photovoltaic panels are mainly flat-lay roof photovoltaic installation and inclined-braced roof photovoltaic panel installation. Among them, flat-lay roof photovoltaic involves directly laying flexible photovoltaic components on the finished surface of the roof; inclined-braced bracket installation refers to the installation of roof photovoltaic panels on counterweight foundations or piers by relying on inclined bracing brackets.

[0003] The disadvantages of the above two schemes are: 1. Flat roof photovoltaic panels are greatly affected by the flatness of the finished roof surface, which is prone to unevenness and water accumulation, affecting roof drainage; 2. Flat roof photovoltaic panels affect heat dissipation; 3. Flat roof photovoltaic panels are located at a low position and are easily stepped on; 4. Braced roof photovoltaic panels require a large variety and number of support structures, which is not economical in the use of materials and consumes a lot of labor.

[0004] Therefore, there is an urgent need for a photovoltaic roof installation method that fully utilizes the characteristics of elevated roofs and the installation characteristics of photovoltaic panels, so as to meet both the requirements of building structure and the requirements of building function and energy conservation.

[0010] In a preferred embodiment, the lower part of the double-channel steel member is designed with a chamfer, which allows for flexible control of the installation angle of the photovoltaic panel assembly.

[0011] In a preferred embodiment, the number of photovoltaic panels in a single photovoltaic work group is greater than or equal to 2, which can be flexibly adjusted according to actual needs. Preferably, it is 2-4 panels.

[0012] In a preferred embodiment, the anchor bolts may be pre-embedded in the concrete support.

[0013] In a preferred embodiment, the top elevation of the concrete support is 25-30 cm above the finished roof surface.

[0014] The main advantages of this utility model are: (1) The form of the elevated roof used in this utility model is conducive to roof ventilation, heat insulation and heat dissipation of photovoltaic panels.

[0018] (5) The concrete support and roof structure slab described in this utility model are integrally cast, which effectively prevents water and leakage.

[0019] The specification of this utility model contains numerous technical features distributed across various technical solutions. Listing all possible combinations of these features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described utility model, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which should be considered as described in this specification), unless such a combination of technical features is technically infeasible. For example, one example discloses feature A+B+C, and another example discloses feature A+B+D+E. Features C and D are equivalent technical means that serve the same function, and technically only one needs to be used; they cannot be used simultaneously. Feature E can technically be combined with feature C. Therefore, the solution A+B+C+D should not be considered as described because it is technically infeasible, while the solution A+B+C+E should be considered as described. Attached Figure Description
