Description

Technical Field

[0001] This invention relates to the technical field of building structures, and in particular to a modular transverse water-guiding covering structure. Background Technology

[0002] As photovoltaic applications expand from ground-mounted power stations to building roofs and facades, there is a growing demand in engineering for using photovoltaic systems as building exterior covering components. In addition to generating electricity, building exterior covering components must also provide long-term enclosure functions, including rain and seepage prevention, load-bearing and wind uplift resistance, thermal expansion and contraction adaptation, durability, and maintainability.

[0003] However, existing photovoltaic modules are mainly designed with power generation and module integrity as the design goals, rather than being designed to bear the responsibility of building envelope load and waterproofing. Their module edges, seams, and fixing parts lack the shielding, overlapping, diversion, and drainage paths commonly used in roof panels or curtain wall systems. Under conditions of wind pressure, capillary action, or gravity accumulation, water can easily enter under the module along the seams, and waterproofing reliability often depends on additional sealing and auxiliary structures.

[0004] To compensate for the above deficiencies, silicone rubber seals and auxiliary drainage structures (such as M-shaped water channels) are often used in engineering. However, silicone rubber seals are sensitive to the condition of the substrate and the construction process. They are prone to aging, cracking or adhesion degradation under long-term exposure to ultraviolet rays, temperature difference cycles and humid and hot environments. The sealing performance decreases over time and it is difficult to ensure consistency on site. Auxiliary drainage structures increase the number of structural layers and connection interfaces, increasing the potential leakage points. Under conditions of rainwater collection, pollution deposition or thermal expansion and contraction, water accumulation, blockage or overflow is likely to occur. Moreover, inspection and maintenance are inconvenient, affecting the long-term reliability of waterproofing.

[0005] In addition, photovoltaic modules are often installed on corrugated steel roofs in engineering projects, with the corrugated steel roofs bearing the waterproofing and load-bearing load, and the modules are then fixed by brackets or clamps. However, corrugated steel roofs rely on overlapping and screw holes combined with gaskets / sealant for waterproofing. Perforation damages the coating, and the sealing material is prone to aging, corrosion, loosening, and leakage over time. At the same time, corrugated steel roofs use a fixed profile, and the overlapping parts are usually accompanied by cross-sectional superposition and local thickness increase, resulting in abrupt height changes at the installation interface. Brackets or clamps are prone to geometric interference or insufficient fit in the overlapping area, resulting in local stress concentration and uneven distribution of pre-tightening force after tightening. This may lead to uneven pressure on the sealing structure and local seal failure (such as gasket deformation or decreased sealing performance due to aging of the sealing material), thereby increasing the risk of leakage. After failure, it is often necessary to disassemble the modules and brackets for inspection and repair, which causes great construction interference and high maintenance costs.

[0006] In summary, existing approaches such as "conventional components + sealing / water channels" or "color steel roof tiles with added components" cannot simultaneously meet the building envelope requirements of waterproof reliability, structural adaptability, aesthetic consistency, and maintenance controllability over the building's lifespan. Therefore, the industry urgently needs a photovoltaic (PV) coverage product system for building envelope applications. This system would enable PV coverage units to perform waterproofing and structural stability functions on roofs and / or facades, reducing reliance on additional sealing and auxiliary drainage structures and achieving long-term rain and seepage prevention. Simultaneously, this product system should be able to form waterproof flat tiles / covering panels that can replace color steel roof tiles, providing a smoother and more aesthetically pleasing appearance while reducing engineering risks such as perforation, seal aging, and high maintenance costs. Furthermore, it should be able to be further expanded into high-end envelope systems suitable for building curtain walls and curtain wall roofs to meet even higher requirements for aesthetic consistency, reliability, and engineering adaptability, thereby supporting the engineering application of Building Integrated Photovoltaics (BIPV) in curtain wall and roof applications.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a modular transverse water-guiding cover structure, comprising multiple cover units, adjacent cover units being assembled longitudinally and / or laterally, each cover unit having a longitudinally extending water-blocking edge structure on both sides that is higher than the middle of the cover unit, and after the upper and lower adjacent cover units are assembled, a transverse water-guiding groove is formed between the water-blocking edge structures; the longitudinal seam between the left and right adjacent cover units is set opposite to the outer side of the water-blocking edge structure, and the transverse water-guiding groove is set opposite to the inner side of the water-blocking edge structure, so that rainwater entering the transverse water-guiding groove and rainwater in the middle area of ​​the exposed surface of the cover unit are restricted between the water-blocking edge structures under the action of the water-blocking edge structures, and are prevented from crossing the water-blocking edge structures and entering the longitudinal seam; Each of the covering units has a receiving portion recessed at its upper end relative to the exposed surface, and a receiving portion that mates with the receiving portion at its lower end; when the upper and lower adjacent covering units are assembled, the upper and lower adjacent covering units are fitted together, and the exposed surfaces of each covering unit are kept flush. The longitudinal seam is provided with a waterproof structure and / or a flow guiding structure.

[0008] Furthermore, the inner sides of the water-blocking edge structures on both sides are provided with water-guiding channels along the longitudinal direction. The water-guiding channels are connected to the transverse water-guiding channels and are interconnected with the central area of ​​the exposed surface of the covering unit for water guidance.

[0009] Furthermore, a transverse sealing strip is provided at the transverse seam corresponding to the transverse water guide channel, and the top surface of the transverse sealing strip is flush with the exposed surface of the covering unit.

[0010] Furthermore, the outer side of the water-blocking edge structure is provided with a longitudinal guide portion, and a guide strip extending longitudinally is provided below the longitudinal seam. The longitudinal guide portions on adjacent covering units are arranged within the same section of the guide strip.

[0012] Furthermore, the longitudinal seam is provided with locking fasteners for connecting adjacent covering units; the waterproof structure is provided with quick-release components that can be detachably connected to the guide strip.

[0013] Furthermore, the waterproof structure includes an upper waterproof cover strip with an inverted U-shaped groove, which is located above the longitudinal joint and forms a waterproof covering structure. The waterproof cover strip is composed of multiple sub-waterproof cover strips connected end to end, with the lower part of the upper sub-waterproof cover strip accommodating the upper part of the lower sub-waterproof cover strip to form an accommodating fit and achieve continuous waterproofing. A quick-release connection structure is provided between the waterproof cover strip and the guide strip to fix the waterproof cover strip above the longitudinal joint.

[0014] Furthermore, the covering unit includes a flow guiding unit and a functional panel disposed in the middle area of ​​the upper surface of the flow guiding unit, wherein the functional panel is one of a photovoltaic panel, a glass panel, a stone panel, or a metal panel.

[0015] Furthermore, the flow guiding unit of the covering unit is connected to the functional panel by sealing and bonding around the perimeter or at the contact surface, or the covering unit is integrally molded from one of the following: metal, composite material, ceramic, glass, or plastic.

[0016] Furthermore, the middle part of the flow guiding unit forms a receiving frame; the functional panel includes an upper panel sealed and installed on the upper surface of the receiving frame, and a lower panel sealed and installed on the lower surface of the receiving frame; one or more functional layers are selectively provided in the area enclosed by the receiving frame, the functional layers being one or more of the following: thermal insulation layer, heat exchange layer, transparent layer, and translucent layer, or the area enclosed by the receiving frame is a cavity.

Secondly, it can also form a waterproof flat tile / covering board that can replace the color steel plate type of roof covering method, and the power generation layer can be attached on it to achieve a flatter and more beautiful appearance and a longer system life, while reducing the engineering risks caused by perforation, sealing aging and high maintenance costs. Third, a photovoltaic module structure with waterproof function is formed. Based on this structure, a high-end enclosure system form for curtain walls and curtain wall roofs can be realized, meeting higher requirements for appearance consistency, reliability and engineering adaptability, thereby realizing the application of building-integrated photovoltaics.

Detailed Implementation

[0020] To facilitate understanding of the present invention, it will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly fixed to that element, or one or more intermediate elements may exist between them; when an element is described as being "connected to" another element, it can be directly connected to that element, or one or more intermediate elements may exist between them. The directional terms "upper," "lower," "left," "right," "inner," and "outer," etc., used in this specification are only used to describe the relative positional relationships of the components in the accompanying drawings and do not constitute a limitation on the scope of protection of the present invention.

[0021] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for describing particular embodiments only and is not intended to limit the invention. "and / or" refers to any one or more combinations of the listed items.

[0022] like Figures 1 to 11As shown, the present invention provides a modular transverse water-guiding cover structure, including multiple cover units 1. Adjacent cover units 1 are assembled longitudinally and / or laterally. Water-retaining edge structures 16 extending longitudinally and higher than the middle of the cover unit 1 are formed on both sides of the cover unit 1. After the upper and lower adjacent cover units 1 are assembled, a transverse water-guiding channel 2 is formed between the water-retaining edge structures 16. The longitudinal joint between the left and right adjacent cover units 1 is set opposite to the outer side of the water-retaining edge structure 16, and the transverse water-guiding channel 2 is set opposite to the inner side of the water-retaining edge structure 16, so that water can enter the transverse water-guiding channel. Rainwater from the 2 and the rainwater in the middle area of ​​the exposed surface of the covering unit 1 are confined between the water-blocking edge structures 16 by the action of the water-blocking edge structures 16, and are prevented from crossing the water-blocking edge structures 16 and entering the longitudinal joint; the upper end of each covering unit 1 is recessed downward relative to the exposed surface to form a receiving part 11, and the lower end is provided with a receiving part 12 that cooperates with the receiving part 11; when the upper and lower adjacent covering units 1 are assembled, the upper and lower adjacent covering units 1 are made to form a receiving fit, and the exposed surfaces of each covering unit 1 are kept flush; a waterproof structure and / or a diversion structure are provided at the longitudinal joint.

[0023] The inner sides of the two water-blocking edge structures 16 are respectively provided with longitudinal water-guiding channels 13. The water-guiding channels 13 are connected to the transverse water-guiding channels 2 and are interconnected with the central area of ​​the exposed surface of the covering unit 1 for water guidance. Specifically, the water-guiding channels 13 on both sides are smoothly connected to the transverse water-guiding channels 2 through inclined surfaces, which allows rainwater flowing into the transverse water-guiding channels 2 to flow smoothly into the water-guiding channels 13 and prevents rainwater from accumulating in the transverse water-guiding channels 2.

[0024] A transverse sealing strip 3 is installed at the transverse joint corresponding to the transverse water guide channel 2. The top surface of the transverse sealing strip 3 is flush with the exposed surface of the covering unit 1. The transverse sealing strip 3 can play a certain sealing role, preventing rainwater from completely flowing into the transverse water guide channel 2 and preventing it from seeping into the room. Through the water-blocking edge structure 16, the longitudinal joint is isolated from the transverse joint, and no connection is formed. Rainwater seeping into the transverse joint will only enter the transverse water guide channel 2 and be discharged through the water guide ditch 13; while rainwater seeping into the longitudinal joint will flow to the longitudinal guide part 14 and the guide strip 4, and will not flow into the transverse water guide channel 2. See details. Figure 6 As shown, a transverse sealing strip 50 is provided at the point where the receiving part 11 and the receiving part 12 meet to further prevent air leakage and improve sealing performance.

[0025] The outer surface of the water-blocking edge structure 16 is provided with a longitudinal guide section 14, and a guide strip 4 extending longitudinally is provided below the longitudinal joint. The longitudinal guide sections 14 on adjacent covering units 1 are located within the same section of guide strip 4. This ensures that even if rainwater seeps into the longitudinal guide section 14, it will be guided into the guide strip 4, preventing rainwater from directly seeping into the room, thus achieving a multi-layered water-guiding and waterproofing structure. The guide structure at the longitudinal joint can be a structure formed by the longitudinal guide section 14 and the guide strip 4 working together.

[0026] The guide strip 4 is composed of multiple sub-guide strips connected end-to-end. The lower part of the upper sub-guide strip is accommodated by the upper part of the lower sub-guide strip to form an accommodating fit and achieve a continuous seal. The guide strip 4 is concave, and a longitudinal sealing strip 5 is provided on its side plate. In the assembled state, the longitudinal sealing strip 5 forms a sealed fit with the adjacent covering unit 1. Specifically, a sealing structure is provided between adjacent sub-guide strips. The sealing structure can be sealant or a sealing strip to ensure sealing and waterproofing. The longitudinal sealing strip 5 ensures that rainwater is confined within the guide strip 4, preventing it from seeping into the room and ensuring the overall structure's sealing and waterproofing. (See details...) Figure 11 As shown, a lower sealing plate 90 can be provided at the joint of adjacent sub-guide strips, and a longitudinal sealing strip 5 is provided at the upper end of the sub-guide strip to further prevent air and water leakage.

[0027] refer to Figures 1 to 4 As shown, this embodiment is manufactured using hardware materials. A locking fastener 6, shaped like an inverted U, is provided within the longitudinal seam for connecting adjacent covering units 1. Both sides of the locking fastener 6 are respectively engaged within the longitudinal guide portion 14 and fixedly connected to the support beam 9 by bolts. A connecting buckle 30 is welded to the bottom of the waterproof cover strip 8. The bottom ends of the connecting buckle 30 have spring clips. A fixing bracket 40, secured with bolts, is provided at the top of the locking fastener 6. The fixing bracket 40 has a slot for engaging with the connecting buckle 30. When actually assembling or disassembling the waterproof cover strip 8, simply aligning the spring clip at the bottom of the connecting buckle 30 with the slot on the fixing bracket 40 achieves a secure connection.

[0028] refer to Figures 5 to 9As shown, this embodiment is manufactured using aluminum alloy. Locking fasteners 6 for connecting adjacent cover units 1 are also provided within the longitudinal seams. The locking fasteners 6 are inverted U-shaped, but have slots on the sides of the longitudinal guide section 14, allowing both sides of the locking fasteners 6 to engage. These locking fasteners 6 are also fixedly connected to the support beam 9 by bolts. A quick-release piece 7 is provided between the waterproof cover strip 8 and the guide strip 4. Each end of the quick-release piece 7 has a spring-loaded buckle, and the bottom of the waterproof cover strip 8 and the top of the guide strip 4 each have a slot. When actually installing or removing the waterproof cover strip 8, simply engage the spring-loaded buckles at both ends of the quick-release piece 7 into the slots of the waterproof cover strip 8 and the guide strip 4 to achieve a fixed connection. See details... Figure 9 As shown, a sealing ring 70 is fitted onto the bolt to further prevent rainwater from seeping into the interior.

[0029] The waterproof structure includes an upper waterproof cover strip 8 with an inverted U-shaped groove. The waterproof cover strip 8 is located above the longitudinal joint and forms a waterproof covering structure. The waterproof cover strip 8 is composed of multiple sub-waterproof cover strips connected end to end by interlocking. The lower part of the upper sub-waterproof cover strip accommodates the upper part of the lower sub-waterproof cover strip to form a accommodating fit and achieve continuous waterproofing. A quick-release connection structure is provided between the waterproof cover strip 8 and the guide strip 4 to fix the waterproof cover strip 8 above the longitudinal joint. See details. Figure 9 As shown, the upper end of the waterproof cover strip is fixed in place by a fixing screw 60, which prevents the waterproof cover body 8 from moving upwards after installation, thus preventing the waterproof cover strip 8 from being opened. See details. Figure 11 As shown, an upper sealing sheet 80 can be provided at the joint of adjacent sub-waterproof cover strips, and an upper sealing strip 100 can be provided on the inner bottom surface of the lower sub-waterproof cover strip to further prevent air and water leakage.

[0030] The covering unit 1 includes a flow guiding unit and a functional panel 15 disposed in the central area of ​​the upper surface of the flow guiding unit. The functional panel 15 is one of a photovoltaic panel, a glass panel, a stone panel, or a metal panel. The flow guiding unit and the functional panel 15 of the covering unit 1 are connected by sealing and bonding around the perimeter or at the contact surface, or the covering unit 1 is integrally molded from one of the following: metal, composite material, ceramic, glass, or plastic. The sealing and bonding connection uses silicone rubber sealant 20.

[0031] The middle part of the flow guiding unit forms a receiving frame; the functional panel 15 includes an upper panel 151 sealed and installed on the upper surface of the receiving frame, and a lower panel 152 sealed and installed on the lower surface of the receiving frame; one or more functional layers 153 are selectively provided in the area enclosed by the receiving frame, and the functional layer 153 is one or more of the following: thermal insulation layer, heat exchange layer, transparent layer, and translucent layer, or the area enclosed by the receiving frame is a cavity.

[0032] In practical applications, this invention can be spliced ​​into a flat surface for use on building facades or roofs. A straight-edge component 10 is provided on the outermost side of the formed plane to better ensure the aesthetics and waterproofing of the entire surface. It can also be assembled into a Building Integrated Photovoltaic (BIPV) structure. Through the structure and principles of this invention, rainwater can be effectively prevented from entering the internal structure and interior, extending service life while meeting requirements for waterproof reliability, structural adaptability, appearance consistency, and maintenance controllability. Furthermore, this invention can form a waterproof flat tile / covering panel that can replace corrugated steel sheet roofing, providing a smoother and more aesthetically pleasing appearance while reducing engineering risks such as perforation, seal aging, and high maintenance costs. In addition, this invention is also a waterproof photovoltaic module structure and can be further extended to a high-end enclosure system suitable for building curtain walls and curtain wall roofs, meeting higher requirements for appearance consistency, reliability, and engineering adaptability, thereby supporting the engineering application of Building Integrated Photovoltaic (BIPV) in curtain wall and roof scenarios.

[0033] In summary, the structure and working principle of the present invention have been fully explained through the above embodiments. For those skilled in the art, various equivalent modifications or substitutions can be made to its specific structural form and connection method without departing from the concept and scope of protection of the present invention, and all such equivalent modifications or substitutions should fall within the scope of protection of the present invention.
