Description

A waterproof photovoltaic building-integrated roof system replacing color steel tiles

technical field

The invention relates to the technical field of photovoltaic buildings, in particular to a waterproof photovoltaic building-integrated roof system that replaces color steel tiles.

Background technique

Laying traditional color steel tiles on the roof of the steel structure workshop increases the construction cost of the workshop. When using traditional photovoltaic power generation brackets to install photovoltaic power generation components on the roof of the traditional steel structure color steel tile workshop, aluminum alloy fixtures, aluminum alloy guide rails, and aluminum alloy medium pressure blocks are required. , aluminum alloy edge pressing blocks, screws, nuts and other materials, resulting in many types of materials, high material costs, complicated and time-consuming installation procedures, and high construction costs.

The traditional steel structure color steel tile roof has a relatively short service life, and there will be rust, damage, water leakage and other phenomena during use. After installing the photovoltaic power generation components on the roof of the traditional steel structure color steel tile factory, if you want to repair the roof, you need to first remove the photovoltaic power generation components on the roof in a large area, and then reinstall the photovoltaic power generation components after the roof is repaired. It will cause damage to the photovoltaic power generation components, and at the same time will increase the workload and increase the maintenance cost.

When the aluminum alloy fixture is fixed on the roof of the traditional steel structure color steel tile factory, punching will destroy the sealing of the original color steel tile, and it is easy to cause water leakage on the roof.

The structural design of waterproof photovoltaic brackets, photovoltaic roof ridges and photovoltaic maintenance channels used in traditional photovoltaic building-integrated roofs is unreasonable, mainly in the following aspects:

(1) When the traditional waterproof photovoltaic bracket is fixed to the roof C-shaped steel beam, it is mainly fixed by self-tapping and drilling. When the self-tapping and drilling are fixed, the worker needs to stand above the C-shaped steel beam and use a hand drill to continuously apply downward force. After the self-tapping thread penetrates the waterproof bracket, it is driven into the C-shaped steel beam, and this process is likely to cause a high-altitude fall accident;

(2) After self-tapping through the waterproof photovoltaic support, if the power of the hand drill is not well controlled before the C-shaped steel beam is penetrated, it is easy to cause the position of the waterproof photovoltaic support to be displaced, which will eventually cause the actual waterproof photovoltaic support. installation error;

(3) The waterproof photovoltaic support is penetrated by the self-tapping thread, and there is a hidden danger of water leakage in the later stage of the penetration;

(4) The use of self-tapping to fix the waterproof photovoltaic bracket has the potential safety hazard of being unstable;

(5) The size of the upper and lower ports of the vertical water guide groove of the traditional waterproof photovoltaic support is the same. When connecting the two vertical water guide grooves, a connecting piece is generally used for connection, and the position of the connecting piece is generally sealed with structural adhesive. The steel structure roof has a large temperature difference between winter and summer, day and night, and the structural adhesive will age after a long time. If the connecting piece is loose, it is easy to cause water leakage. The structural design also has the disadvantages of high material cost, complex structure, low installation efficiency and high construction cost;

(6) The horizontal water guide channel of traditional waterproof photovoltaic bracket generally adopts a rectangular design and is placed on the top of the vertical water guide channel. The upper vertical edge of the guide gutter is higher than the lower vertical edge, and when the rainwater flow is large, the rainwater overflows from the lower vertical edge of the horizontal gutter;

(7) The traditional waterproof photovoltaic support adopts a rectangular horizontal water guide trough placed above the vertical water guide trough before laying photovoltaic power generation components, resulting in the difference between the lower frame of the upper photovoltaic power generation module and the upper frame of the lower photovoltaic power generation module. There is a gap between them, which will increase the inflow of rainwater in the horizontal gutter, which is easy to cause rainwater to overflow from the lower vertical edge of the horizontal gutter. Because the gap is too large, debris will fall into the horizontal gutter and affect the drainage. In order to solve the problem that the gap between the upper and lower photovoltaic power generation modules is too large, traditional waterproof photovoltaic brackets are generally sealed with structural rubber strips or aluminum with a T-shaped structure. The above two solutions will cause material waste, increase the difficulty of construction, and increase the difficulty of disassembly and maintenance of photovoltaic power generation modules in the later stage;

(8) For the traditional waterproof photovoltaic support, the photovoltaic power generation components are laid after the support is fixed. After the photovoltaic power generation components are laid, they are fixed with aluminum alloy side pressure blocks, aluminum alloy middle pressure blocks, screws and nuts. During the process of pressing blocks and aluminum alloy edge pressing blocks, workers are easy to trample or press the photovoltaic power generation components; if some photovoltaic power generation components need to be replaced later, it is also easy for workers to step on or press the surrounding photovoltaic power generation components during the process of removal and replacement. For power generation components, stepping or pressing on the surface of the photovoltaic power generation components will cause the internal cells of the photovoltaic power generation components to crack, and the cracks of the cells will directly affect the service life and power generation of the photovoltaic power generation components;

(9) Each aluminum alloy side pressure block, aluminum alloy middle pressure block, screws and nuts need to be assembled on the construction site, resulting in an increase in the amount of on-site construction, and it is easy to lose small parts such as screws and nuts during the assembly process. Affect the overall construction progress;

(10) After the traditional waterproof photovoltaic support and photovoltaic power generation components are installed, the photovoltaic cables of the photovoltaic junction box on the back of the photovoltaic power generation components have no fixed position, causing the photovoltaic cables to hang on the back of the photovoltaic power generation components disorderly, which affects the overall appearance and also exists. Security risks;

(11) After the traditional waterproof photovoltaic support is fixed, the photovoltaic power generation components are laid. Because the traditional waterproof photovoltaic support uses aluminum alloy medium pressure blocks to fix the photovoltaic power generation components on the left and right sides, and due to the size of the aluminum alloy medium pressure block, the After the photovoltaic power generation modules on the left and right sides are fixed, there will be a gap of about 2 to 3 cm. Because the gap between the photovoltaic power generation modules and the modules is too large, the rainwater flow in the vertical gutter will increase. The rainwater overflows the vertical gutter; at the same time, because the gap between the photovoltaic power generation components is too large, the roof resources are wasted, the available area of the roof is greatly reduced, and the installed capacity of the photovoltaic power generation components on the roof is reduced; If the gap is too large, the sundries will fall into the longitudinal gutter, causing blockage and affecting the drainage effect;

(12) The traditional photovoltaic roof is formed by splicing multiple pieces of the same structure. During the splicing process, there is a gap between the roof structure and the structure. The method to deal with the gap between the structures is to lay a steel plate on the two roof structures, and then use self- The tapping holes are respectively punched and fixed, and the holes are easy to leak; some photovoltaic roof ridges are designed to be concave, which turns the roof ridge into a large water channel. If the rainwater cannot be discharged in time, water leakage is likely to occur;

(13) The maintenance channel of the traditional photovoltaic roof system cannot be flexibly combined and changed according to the roof conditions during installation;

(14) Traditional photovoltaic roof systems generally do not set up lighting belts.

Therefore, in view of this, the inventor, adhering to years of rich experience in design, development and actual production in the related industry, researches and improves the existing structure and defects, and provides a waterproof photovoltaic building-integrated roof system that replaces color steel tiles. In order to achieve a more practical purpose.
