Description

A solar color steel polymer coil composite roofing system

technical field

The invention relates to the field of house building materials, and specifically relates to a power generation and waterproof integrated roof system that combines solar power generation and building waterproofing technology with the current trend of building photovoltaic integration.

Background technique

Compared with high-rise residential buildings, the roofs of many industrial plants with light steel structure roofs and large-scale public buildings are generally well-lit, which can provide places for solar power generation, so that they can be self-contained and bring clean energy benefits to enterprises. However, the current installation method of fixing and supporting traditional photovoltaic modules on the light steel structure roof is to install a large number of brackets, installation nails, pressing blocks and installation holes on the original color steel tiles. These brackets, mounting nails and mounting holes are very likely to cause building water leakage in long-term operation. In addition, the mass of the additional brackets and pressing blocks, etc., coupled with the mass of the photovoltaic modules and the mass of the original light-weight steel structure color steel tiles, will increase the static load of the long-span light-weight steel structure roof, leaving a certain security risks. In addition, the original color steel tiles are covered and blocked by photovoltaic modules, and these color steel tiles cannot effectively perform architectural functions such as blocking sunlight, resulting in a waste of functions.

In the long run, solar photovoltaic buildings should be built with high efficiency, low energy consumption and must be economical in essence without sacrificing functionality, artistry, and comfort. In view of the above situation, it is necessary to develop a building photovoltaic integrated roof system that is more suitable for light steel structure buildings, simple to install, economical and convenient.

The solar polymer coil color steel composite roofing system of the present invention realizes the functions of heat preservation and heat insulation and blocking solar radiation through the general photovoltaic module, U-shaped color-coated steel tile, and heat preservation and heat insulation layer in the system.

The beneficial effects of the present invention are:

The outstanding advantage of the present invention is that the structure is self-waterproof and does not damage the waterproof layer of the traditional light-weight steel structure roof. A large number of perforations are required to install the guide rails and brackets of the solar modules, which fundamentally avoids damaging the waterproof layer of the traditional roof. The installation of the solar polymer coil color steel composite roof system does not need to cut the insulation layer or damage the waterproof layer or roof panel.

The outstanding advantage of the present invention is that it has outstanding maintainability compared with current solar tiles. The traditional solar tile is that the solar cells and the tiles of the building are bonded together by means of hot pressing, etc., and the tiles are occluded and lapped to form waterproofing. In the long-term operation, when individual solar tiles fail, some tiles around the faulty solar tiles need to be removed, and in some cases, even part of the roof building structure needs to be removed to remove the overlapping faulty tiles. In the solar power generation part of the present invention, the general-purpose photovoltaic module is installed on a square structure surrounded by color-coated steel tiles using fasteners, which can be easily disassembled and assembled quickly. When maintaining a faulty solar cell module, only the fastening member between the faulty general solar cell module and the zigzag structure needs to be removed, and then maintenance and overhaul can be performed.

The invention avoids the overlapping of the functions of common solar modules and color-coated steel plates, and saves most of the color-coated steel plates. In the traditional solar power generation system directly installed on the roof of the color-coated steel plate, the color-coated steel plate on the shielded part of the ordinary solar module cannot function to block solar radiation, resulting in a waste of materials. And the present invention has adopted square color coated steel plate tile, has saved the colored coated steel plate.

The outstanding advantage of the invention is that it is very light. It eliminates the guide rails and brackets of traditional roof solar equipment, and saves most of the color-coated steel plates. It is a solution for light-weight roofs such as metal structure roofs.

The outstanding advantage of the present invention is to carry forward the characteristics of rapid construction of large-area color steel roofs, and is a solution for light-weight roofs such as metal structure roofs. Because the installation of supporting equipment such as related solar panel brackets is not required, the construction labor intensity of the present invention is small and the construction speed is fast.

The outstanding advantage of the present invention is that there is an air barrier of more than 5 cm between the ordinary solar modules and the thermal insulation material in this system, which not only effectively increases the thermal insulation effect of the roof, but also effectively reduces the high temperature and hot spot effect of the photovoltaic modules In extreme cases, there is a risk of roof fires.

The outstanding advantage of the present invention is that the junction boxes and connecting cables of ordinary solar modules in this system are routed downwards, and there is an air barrier of more than 5 cm between the ordinary solar modules and the thermal insulation material. In this way, the roof is neat and beautiful, easy to clean, and effectively prevents the aging of the junction box and connecting cables from being exposed to rain, snow, and sunlight. And the electrical system is easy to overhaul and maintain.

The outstanding advantage of the present invention is that its U-shaped color-coated steel plate parts make the system possess certain flexibility, which can be suitable for flat roofs and curved roofs. Therefore, the present invention not only has the flexibility of the current flexible thin film solar cell roofing system, but also possesses the low-cost characteristics that the flexible thin film solar cell lacks due to the use of crystalline silicon solar cells.

The outstanding advantage of the present invention is that the U-shaped structure of its U-shaped color-coated steel plate parts makes the system have a certain flexibility, which can reduce the destructive effect of the roof expansion and contraction deformation on the photovoltaic modules caused by thermal expansion and contraction.
