Fig. 2 be photovoltaic roof shown in Fig. 1 A ?A sectional view, it illustrates the waterproof construction 30 between photovoltaic roof tile 10 and metal bituminized shingle 20.This waterproof construction 30 comprises drainage ridge 34, first flexible water sheet 35 rides on drainage ridge 34, overlap with the top surface edge of metal bituminized shingle 20 simultaneously, second flexible water sheet 36 is stacked on the first flexible water sheet 35, overlap with the top surface edge of photovoltaic roof tile 10, as which form reliable waterproof sealing simultaneously.This drainage ridge is arranged in roof support structure.
This drainage ridge 34 is included in base that roof support structure is installed and protrudes from the top ridge on metal bituminized shingle and photovoltaic roof tile surface, for the first flexible water sheet and the second flexible water oblique cut grafting thereon, forms drainage domatic.Alternatively, drainage ridge extends along overboard direction, and its cross section is L-type or T-shaped of falling.
This waterproof construction 30 is also included in hard-wired first angle-shaped piece 32 on metal bituminized shingle 20, hard-wired second angle-shaped piece 33 and buckle 31 on photovoltaic roof tile 10, this buckle 31 and the first angle-shaped piece 32 and the second angle-shaped piece 33 are removably linked together by screw etc.
Buckle 31 inside defines enclosure space, for holding external terminal and the cabling 13 of photovoltaic roof tile 10.This waterproof construction also has wind resistance and to take off, at roofing laterally and the effect of overboard direction stretch-proof.
Preferably, the first angle-shaped piece 32 is pressed on the first flexible water sheet 35, as the collision mat between metal bituminized shingle 20, to improve water resistance.
Above-mentioned first flexible water sheet and the second flexible water sheet obtain by cutting waterproof roll.
In the utility model, not only form waterproof construction 30 between the left side of photovoltaic roof tile and metal bituminized shingle, and between the right side of photovoltaic roof tile and metal bituminized shingle, also forming the second waterproof construction 40, the enclosure space that this second waterproof construction 40 is formed can be less than the volume protected from water in left side.
Wherein, photovoltaic roof also comprises the tile being cut into other sizes by metal bituminized shingle according to construction requirement, lays to facilitate roofing scene.
In the utility model when guaranteeing roof tile decorative effect and using function, the photovoltaic roof tile adopting monolithic area larger is single-row setting, while can obtaining enough generated outputs, significantly reduces operation and maintenance cost.
Below the paving method of waterproof construction of the present utility model is described in detail, comprises the following steps:
The first step, installs drainage ridge, metal bituminized shingle of from bottom to top mating formation in turn, and after often having laid piece of metal bituminized shingle, lays first flexible water sheet between surperficial edge and drainage ridge thereon;
Second step, photovoltaic roof tile of from bottom to top mating formation in turn, and after often having laid a slice photovoltaic roof tile, between photovoltaic roof tile and drainage ridge, lay the second flexible water sheet;
3rd step, installs the first angle-shaped piece and the second angle-shaped piece;
4th step, the wiring of photovoltaic roof tile;
5th step, finally installs buckle.
Above-mentioned paving method of the present utility model, has and interlocks step by step, rationally compact feature, is applicable to dissimilar plane watt and does waterproofing work.
Photovoltaic roof tile 10 of the present utility model is laid photovoltaic film 12 using metal pitch composite plate as matrix 11 and is formed, and meets photovoltaic film to thing followed roofing after watt surperficial planeness, large area light weight and large area to the requirement of the aspects such as tile deflection degree simultaneously.
By pitch base material and metal forming, pressing under predetermined temperature and pressure condition is formed metal pitch composite plate, pitch base material and metal forming are when pressing, predetermined temperature and pressure makes pitch substrate surface soften and merges with the asphaltic base colloid melted, and combines well to make metal forming and pitch base material.Pitch base material comprises PE thin layer, the first bitumen layer, tire basic unit, the second bitumen layer successively from bottom to top layer, wherein, is provided with the special glue-line of asphaltic base between the second bitumen layer and metal forming.This tire basic unit is preferably glass fiber blank base or polyester base.
Compared with the photovoltaic roof tile of the equal photovoltaic area of other structures, although the manufacturing cost of photovoltaic roof tile monolithic of the present utility model watt is higher, but the overall use cost comprising each links such as installation, maintenance obviously reduces, solve photovoltaic tiles exposed area of the prior art little, need a large amount of connections between tile and cause that product itself is unreliable, loaded down with trivial details defect of mating formation.
Preferred embodiment:
The specification of photovoltaic roof tile: length is not less than 1m, preferably 2 ~ 6 meters; Width is not less than 0.29m, preferably 0.29 ~ 0.51 meter; Thickness is no more than 8mm, preferably 4 ~ 8mm; Photovoltaic roof tile mat formation after the exposed area of monolithic photovoltaic roof tile be not less than 0.5m
