Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

With the large-scale installation of photovoltaic power stations, ground photovoltaic land is less and less, and install photovoltaic module on building, can provide the place for photovoltaic power generation on the one hand, on the other hand also brings new selection and element for the building. The number of roofs suitable for mounting the photovoltaic modules is large, but the large-span metal roof is more suitable for application of the photovoltaic modules in batch production. BIPV is a technology for integrating a solar power generation assembly (photovoltaic assembly) into a building, and the photovoltaic assembly and a roof panel on the outer surface of the building can be combined together in a gluing mode and the like, so that the building has photovoltaic power generation capacity.

In the BIPV technology, the materials used for the large-span metal roof mainly comprise an aluminum-zinc plated steel plate, a stainless steel plate, an aluminum alloy plate and the like, common roofs comprise roofs of industrial factory buildings, and roofs of public buildings such as airports, railway stations, gymnasiums, convention and exhibition centers and the like. These roofs are characterized by a large floor space, often several tens of meters in height. Due to the characteristics of the roof, the roof is easily affected by strong wind to cause wind uncovering damage, so the wind uncovering resistance of the roof is a problem to be solved in important places for the large-span metal roofs. Similarly, if a photovoltaic system is installed on the large-span metal roof, the influence on the wind uncovering resistance of the metal roof after the photovoltaic system is installed needs to be considered in an important way.

The existing method for installing the photovoltaic module on the metal roof mainly comprises the steps of installing a guide rail bracket on a lock edge rib of the metal roof by using a wind-resistant clamp, and then installing the photovoltaic module on a guide rail fixed by using the guide rail bracket. Further, through metal support fixed mounting between the roofing purlin that metal roofing and roofing below were weighed, consequently, it is corresponding with metal support's position to ensure the mounted position that the anti-wind pressed from both sides, just can reduce the injury to the stress concentration of metal roofing.

Therefore, the existing method for installing the photovoltaic module on the metal roof can generate three problems, firstly, after the metal roof is installed, the position of the metal support cannot be seen above the metal roof, so that the installation position of the wind-resistant clamp is difficult to find, and the wind-resistant clamp is installed at a position deviated from the metal support, so that under the condition of receiving wind suction force or load, concentrated load on the wind-resistant clamp can be directly loaded on a weak metal roof plate, and the metal roof plate is damaged. Secondly, because the interval of metal support is the interval phase-match with the roofing purlin, after the anti-wind clamp was installed at the position that the metal support corresponds, the interval of guide rail will be unanimous with the interval of roofing purlin to lead to the installation photovoltaic module the mounting point on the guide rail optimum stress point position for photovoltaic module not, this bearing capacity that can reduce photovoltaic module. The use of double layer rails is required to solve this problem and increases the cost of the system and the weight bearing of the roofing system. Third, because the anti-wind presss from both sides to rely on static friction fixed, for guaranteeing that the installation is reliable, it accompanies very big clamp force with just needing anti-wind, too big clamp force can make between the metal roofing and the metal support of clamping position closely combine, because metal roofing expend with heat and contract with cold deformation is bigger, it has certain clearance to ensure generally between metal roofing and the metal support, just can guarantee can sliding relatively between metal roofing and the metal support, thereby release expend with heat and contract with cold's stress, if anti-wind presss from both sides to press from both sides metal roofing and metal support and tightly leads to the relative metal support of metal roofing can not slide, long-time use will greatly reduced metal roofing's life.
