In the commercial roofing, the amount of metal roofing is the largest, but problems such as leakage, rust, etc. also occur. The existing traditional way is to install the photovoltaic guide rail and the assembly on the existing color steel tile by adopting a clamp. The common galvanized color steel tiles are adopted for the common metal roof, and are corroded, peeled and damaged quickly when exposed to the sun and rain. The service life of a typical metal roof is 10 to 15 years, which is not a significant match with the 25-year operation of a photovoltaic system. And the metal roof is formed by buckling and splicing dozens of centimeters wide color steel tiles, adopts rigid connection, and has leakage hidden trouble at the splicing seams. The most common leakage is mainly at the detailed joint parts of a ridge, a lighting belt, a fan, a roofing pipeline, a gutter and the like. The thin nodes can not be connected with the large-surface color steel tile into a whole, and only can be locally sealed in an auxiliary way by adopting sealing paste or waterproof coiled materials. Leakage begins to occur in three to five years. The leakage repair is repeated repeatedly and cannot be cured radically. On the one hand, frequent personnel on-site maintenance and cleaning and the self weight (15 kg/m) of the photovoltaic module can increase the deformation of the color steel tile when the photovoltaic system is installed on the roof. In addition, under the action of wind load, the clamp and the wave crest of the color steel tile have long-term friction, so that the corrosion of the color steel tile is aggravated, and larger leakage is caused. Roof renovation once every decade results in huge losses for both owners and photovoltaic investors.

As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, fig. 1 is an exemplary structural schematic of a fused tile photovoltaic roof structure, according to some embodiments of the present disclosure. A fused tile photovoltaic roof structure as shown in fig. 1, comprising: the photovoltaic component comprises a supporting structure 1, a heat-insulating layer 2, a fusion tile layer consisting of a plurality of fusion tiles 3 and a plurality of light photovoltaic plates 4;

the support structure 1 is located at the lowermost layer of the fused tile photovoltaic roof structure for supporting other roof structures above it. That is, the support structure may be used to support the insulation layer 2, the fused tile and the photovoltaic module. As shown in fig. 1, the support structure 1 may include purlins 11 and a steel mesh 12. The steel wire mesh 12 is placed above the purline 11 and supported by the purline 11. The steel wire mesh 12 may be laid on the purlin 11 and fixed to the purlin 11 by steel wires or the like. The heat preservation layer 2 is arranged above the steel wire mesh 12 and is supported and stabilized by the steel wire mesh 12.

The heat-insulating layer 2 is positioned on the upper layer of the supporting structure 1. As shown in fig. 1, the insulating layer 2 is disposed on the upper layer of the steel wire mesh 12, and the material of the insulating layer 2 may be glass wool or insulating cotton.

The fusion tile layer is arranged on the upper layer of the heat preservation layer 2 and consists of a plurality of fusion tiles 3. The fusion tiles 3 are mutually overlapped to form a whole and bear the photovoltaic assembly in a public mode. The adjacent fusion tiles are partially overlapped with each other. Here, the adjacent includes both left and right adjacent and front and back adjacent. The lap joint parts of the adjacent fusion tiles are fixed by hot air welding. Meanwhile, each fusion tile forming the fusion tile layer is fixed on the purline through a fixing piece, and each fixing piece is covered with a waterproof coiled material. The fastener may be a fastener such as a self-tapping screw or the like. The waterproofing roll may be a PVC roll or a TPO roll. The fused tile layer can be installed, for example, by laying the fixed steel wire mesh 12 and the insulating layer 2 on the purline 11 and then laying the fused tile layer. And overlapping the mutual parts of the adjacent fusion tiles 3, and fixing the overlapped parts by hot air welding. The fused tile layer is fixed on the purline 11 by using self-tapping screws, and each self-tapping screw is covered with a TPO waterproof coiled material. The fusion tiles 3 are mutually lapped, so that the whole roof forms a closed whole, and the risk of roof leakage is effectively reduced.

The fusion tiles 3 may be formed by compounding a metal plate and a thermoplastic material, and the cross-section of the fusion tiles 3 may be corrugated. The metal plate for compounding into the fusion tile 3 may be a galvanized steel plate, an aluminized zinc steel plate, a galvanized alloyed steel plate, an electrogalvanized steel plate, an aluminum plate, a stainless steel plate, or the like. Meanwhile, the surface of the fusion tile 3 can be provided with a waterproof film, and the waterproof film can be a TPO film and the like. By the metal sheet and the compound formation of thermoplastic material, and from taking waterproof film's integration tile 3, can effectively solve the problem of roofing corrosion when waterproof, prolong the life of roofing.

The photovoltaic module is mounted on the fused tile layer and may be composed of a plurality of light photovoltaic panels 4. For example, the light photovoltaic panel is composed of a plurality of light photovoltaic panels with the self weight of 6-8 kilograms per square meter, and the light photovoltaic panels can reduce the load of a roof and reduce the risk of falling of photovoltaic modules. The light photovoltaic panel can also be a photovoltaic panel with certain flexibility, and when the building roof where the photovoltaic module needs to be installed is a circular arc slope and the slope is large, the flexible photovoltaic panel can be in line with the circular arc roof, so that the risk of hidden cracking of the photovoltaic panel is reduced.

The lightweight photovoltaic panel can include a photovoltaic functional region and an extension region. As shown in fig. 1, the lightweight photovoltaic panel 4 may include a photovoltaic functional region 41 and an extension region 42. The photovoltaic functional area 41 is a main functional area of the light photovoltaic panel 3 for converting light energy into electric energy; the extension region 42 is a region of one turn of the outer periphery of the photovoltaic functional region 41.

Each light photovoltaic panel 4 is directly connected to the fusion tiles 3 constituting the fusion tile layer. When the light photovoltaic panel 4 is installed, the light photovoltaic panel 4 is laid on the fusion tile layer and is mainly supported by two or more wave crests on the fusion tile layer. When the wave crests of the fusion tiles 3 forming the fusion tile layer are trapezoidal isoplanars, the plurality of wave crests can be further coated with the adhesive. The light photovoltaic plate 4 is bonded with the wave crest of the fusion tile 3 through the adhesive, so that the light photovoltaic plate 4 is more firmly connected with the fusion tile layer, and the wind uncovering resistance of the light photovoltaic plate 4 is improved.

The extension region 42 includes a fixing portion 421 and an abutting portion 422. The extensions 42 may be side bars for mounting compounded by the lightweight photovoltaic panel 4 itself. For example, in the production of the light photovoltaic panel 4, a material capable of being welded and fixed, such as a TPO coil or a PVC coil, is laminated on the side of the photovoltaic functional region 41, so that the photovoltaic functional region 41 and the extension region 42 are integrally formed. The extension 42 can also be connected to the extension 42 at the side of the light photovoltaic panel 4 as required before the photovoltaic module is installed. For example, a weldable coil, such as a TPO coil or a PVC coil, is attached around the periphery of an existing common lightweight photovoltaic panel.

The fixing portion 421 is fixed in the wave trough of the fused tile layer by hot air welding. The fixing portions 421 of the adjacent light photovoltaic panels may be fixed on the waterproof layers in the same or different wave troughs. As shown in fig. 1, the fixing portions 421 of the two adjacent left and right lightweight photovoltaic panels 4 are fixed in the same wave trough. The fixing portions 421 of the left and right adjacent light photovoltaic panels 4 may also be fixed in different wave troughs. For example, two adjacent fixing portions 421 may be fixed in two adjacent troughs separated by one peak, or two troughs separated by two or more peaks according to the installation requirement. The fixing portion 421 is welded in the trough by hot air, so that the wind-resisting ability of the photovoltaic module can be effectively improved.

The butt joint 422 is used for butt joint between the adjacent light photovoltaic panels 4. For example, when the roof slope is small, the adjacent light photovoltaic panels 4 may be butted in a flat butt joint manner, that is, the butting parts 422 of the adjacent light photovoltaic panels 4 are butted in a flat joint manner. Referring to fig. 2, fig. 2 is an exemplary top view of adjacent lightweight photovoltaic panel flat interfaces of a fused tile photovoltaic roof structure, according to some embodiments of the present disclosure. As shown in fig. 2, the butt-joints 422 of two adjacent light photovoltaic panels 4 are laid in alignment. For another example, when the slope of the roof is large, the abutting portions 422 of the adjacent light photovoltaic panels 4 may be overlapped with each other, and the overlapped portions may be bonded by an adhesive, fixed by hot air welding, or fixedly connected by other methods. The photovoltaic modules are mutually overlapped and fixed to form a whole, so that accumulated snow can be reduced, and the snow load resistance of the roof is improved.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
