Description
Technical field
The utility model relates to the photovoltaic modulies with construction material function, can load-bearing bilayer waterproof more particularly, to one kind
Photovoltaic roof system.
Background technique
All kinds of buildings that the mankind use all are likely to become production of energy and the immediate place of energy-consuming, it is various live
The roofing of the light on the sunny side of residence, workshop and other buildings can become the supporting body of photovoltaic power generation.Unfortunately largely build
The roof space for building object does not play the effect of photovoltaic power generation carrier.Make full use of roof area be it is a kind of can be in very great Cheng
The effective ways for reducing building energy consumption on degree, solving Building Energy-saving, so that the roof of building becomes many photovoltaic electrics
It stands.
Currently, the solar energy industry scale in China has occupied the first in the world.It is to be appreciated that for the east of economically invigorating region
Portion's coastal economy band, energy shortage after urbanization, building accumulation, soil is few, is unfavorable for developing large-scale ground photovoltaic plant, but
It is very suitable for developing Photovoltaic Building Integration.Although single architecture-integral scale of the project is small, drips and converge sea, and to electric power
The supplement on the spot of shortage, and solve the puzzlement that photovoltaic plant is lost in long distance transmission.
Domestic photovoltaic application is after years development, and either industry development is oriented to, or practical Policy Effect, by recent years
Start gradually from large-scale ground power plant application to distributed power generation mode transition, the distributed power generation based on building enters gold
10 year lead-time.Architecture-integral power generation mode, will with its " low spatial cost, low power transmission and transformation cost, low synthetic assembly at
Originally " the advantages of and following characteristics, become the prior development direction of China's application of solar energy.The additive type (BAPV) of industrial premises is answered
With will gradually eliminate since same Integration of building degree is not high.A large amount of The Factory Roofs all use color steel construction and non-concrete knot
Structure, this makes the load-bearing on roof and service life aspect all very risky.It is well known that the roof service life of color steel construction is extremely
There was only 15 years (less than 15 years since photovoltaic project construction) more, and the agreement that photovoltaic power generation is signed is 25 years, the two is complete
It is complete to mismatch.
Using structurally waterproof conceptual design photovoltaic roofing system, structurally waterproof be can achieve in conjunction with the height of building, right
For the enterprise owner of newly-built industrial premises, there is no need to color steel tiles, are mounted directly architecture-integral photovoltaic roof system generation
For color steel tile, the investment construction expense of color steel tile is also saved；And for those color steel tile service life to the industry needed replacing
Factory roof then haves no need to change the design of workshop original structure, does not need additionally to increase roof carrying, directly uses architecture-integral
Photovoltaic roof system is replaced the former roofing of insertion and becomes technology, art and function in conjunction with original building factory building height
Synthesis provides both artistic and practical photovoltaic system product, further increases the taste of building.
For example, a kind of disclosed BIPV photovoltaic roof of heat radiating type double layer water-proof structure, publication number on Chinese patent
For CN205577274U, including solar photovoltaic assembly, main sink, secondary sink, damping briquetting, component briquetting, ground connection thorn piece, subtract
