Description

Technical Field

[0001] This utility model relates to the field of waterproof building materials technology, and in particular to a prefabricated waterproof and thermal insulation integrated panel and a prefabricated roof photovoltaic system using the same. Background Technology

[0002] Waterproof membranes and insulation boards are both important types of waterproofing materials in building engineering. Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. Insulation boards are mainly used in building walls, roofs, etc., to provide insulation and energy saving.

[0003] In order to promote the application of green building, waterproof membranes and insulation boards are often combined into integrated waterproof and insulation panels. In the process of realizing this utility model, the applicant discovered that existing integrated waterproof and insulation panels have at least the following problems:

[0004] 1. The existing waterproof and thermal insulation integrated panel has a waterproof membrane attached to its upper surface. The waterproof membrane is a soft material and cannot be used to install photovoltaic brackets or photovoltaic systems.

[0005] 2. The mandatory standard for integrated waterproof and thermal insulation panels requires two layers of waterproofing. However, if a photovoltaic system is to be installed, additional fasteners need to be installed through at least part of the integrated panel. Alternatively, during installation, one layer of waterproofing in the integrated waterproof and thermal insulation panel may be damaged, which will reduce the waterproofing performance.

[0006] 3. Previously, after the waterproof and thermal insulation integrated panels were installed, nails were used to fasten them. In rainy or humid weather, moisture may seep into the waterproof and thermal insulation integrated panels, causing the nails to rust and thus creating potential hazards.

[0007] In view of this, how to solve the problems of existing waterproof and thermal insulation integrated panels, such as the inability to install photovoltaic systems due to the soft waterproof membrane, the decline in waterproof performance, and the corrosion of fasteners, has become the research topic to be solved by this utility model. Utility Model Content

[0008] This utility model provides a prefabricated waterproof and thermal insulation integrated panel and a prefabricated roof photovoltaic system using the same, with the aim of solving the problems of existing waterproof and thermal insulation integrated panels, such as the inability to install photovoltaic systems on soft waterproof membranes, reduced waterproof performance, and corrosion of fasteners.

[0009] To achieve the above objectives, the first aspect of this utility model proposes an assembled waterproof and thermal insulation integrated panel, which, from bottom to top, comprises a lower steel plate, a lower foaming layer, a thermal insulation layer, an upper foaming layer, an upper steel plate, and a roll material layer.

[0010] The lower steel plate is a profiled steel plate with multiple forming grooves spaced apart along the laying length direction, and the lower steel plate has a lower overlapping edge formed by a forming groove at the first end facing the laying length direction.

[0011] The lower foam layer fills the forming groove of the lower steel plate and a certain distance above the surface.

[0012] The insulation layer is composed of multiple insulation boards arranged in an array on the upper surface of the lower foam layer.

[0013] The upper foam layer fills a certain distance on the upper surface of the insulation layer.

[0014] The upper steel plate is laid on the upper surface of the upper foam layer.

[0015] The coil layer is laminated to the upper surface of the upper steel plate, and the coil layer has an upper lap edge at the second end in the direction of laying length.

[0016] The integrated waterproof and thermal insulation panel is configured such that, in the state of assembly between adjacent integrated waterproof and thermal insulation panels, the upper overlapping edge of the integrated waterproof and thermal insulation panel at the first end overlaps the roll layer of the integrated waterproof and thermal insulation panel at the second end, and the lower overlapping edge of the integrated waterproof and thermal insulation panel at the second end is assembled on the forming groove of the integrated waterproof and thermal insulation panel at the second end.

[0017] To achieve the above objectives, a second aspect of this utility model provides a prefabricated roof photovoltaic system, which includes a prefabricated waterproof and thermal insulation integrated panel as described in the first aspect of this utility model, and photovoltaic modules mounted on the waterproof and thermal insulation integrated panel.

[0018] The relevant contents of this utility model are explained as follows:

[0019] 1. In the above-mentioned technical solution of this utility model, in view of the problems existing in the existing waterproof and thermal insulation integrated panels, such as the inability to install photovoltaic systems with soft waterproof membranes, reduced waterproof performance, and fastener corrosion, an innovative prefabricated waterproof and thermal insulation integrated panel and a prefabricated roof photovoltaic system using the prefabricated waterproof and thermal insulation integrated panel are designed. The prefabricated waterproof and thermal insulation integrated panel includes, from bottom to top, a lower steel plate, a lower foam layer, an insulation layer, an upper foam layer, an upper steel plate, and a membrane layer. The lower steel plate, upper steel plate, and membrane layer constitute three layers of waterproofing. The composite application of the upper steel plate and the membrane layer makes it possible to install a photovoltaic system. Moreover, the installation of the photovoltaic system will only damage one layer of waterproofing at the installation location, without affecting the other two layers of waterproofing. Therefore, the waterproof performance is better. The lower foam layer and upper foam layer set in the waterproof and thermal insulation integrated panel allow the fasteners to be placed inside the foaming agent and insulation layer without penetrating the upper steel plate. After being filled with foaming agent, there will be no moisture corrosion, avoiding the hidden danger of reduced structural strength in the future.

[0020] 2. In the technical solution of the first aspect above, the thickness of the lower steel plate is 0.5-0.6mm, the thickness of the upper steel plate is 0.2-0.3mm, and the thickness of the roll layer is 1.2-2mm. With this reasonable thickness setting, the waterproof performance of these three layers of waterproofing is good, and the thickness setting of the lower and upper steel plates takes into account both weight and structural strength.

[0021] 3. In the technical solution of the first aspect above, a plurality of the insulation boards are arranged vertically and tightly on the upper surface of the lower foaming layer to improve the compressive strength of the insulation layer, thereby enhancing the overall strength of the entire waterproof and thermal insulation integrated board. The insulation board is a polystyrene extruded board or a rock wool board.

[0022] 4. In the technical solution of the first aspect above, the length of the upper overlapping edge is greater than or equal to 80mm, thereby providing a sufficiently long upper overlapping edge for welding multiple waterproof and thermal insulation integrated panels in the future, and improving the waterproof effect.

[0023] 5. In the technical solution of the first aspect above, the roll layer is made of PVC roll or TPO roll, which has good waterproof effect and high strength.

[0024] 6. In the above-mentioned first aspect of the technical solution, the waterproof and thermal insulation integrated panel further includes fasteners that are fastened to the external ribs. The fasteners pass upward through the lower foaming layer, the thermal insulation layer, and the upper foaming layer from the location of the forming groove. The top of the fasteners abuts against the lower surface of the upper steel plate, and the fasteners do not penetrate.

[0025] 7. In the technical solution of the first aspect above, the lower steel plate of one of the waterproof and heat-insulating integrated panels has two, three, four, five or six forming grooves, which is more flexible and can be selected according to the length required for assembly, avoiding on-site cutting.

[0026] 8. In the technical solution of the second aspect above, the photovoltaic module includes a photovoltaic base selectively disposed at a position corresponding to the position directly above the molding groove, and the photovoltaic base is provided with an upward-opening mounting hole, so as to enable the photovoltaic module to be installed onto the waterproof and heat-insulating integrated board more quickly and firmly.

[0027] 9. In the technical solution of the second aspect above, the photovoltaic module includes a photovoltaic panel and a photovoltaic support. Multiple photovoltaic supports are provided at the bottom of the photovoltaic panel. The photovoltaic support located in the middle is assembled into the photovoltaic base. A connecting layer with the same material as the roll material is provided around the photovoltaic base and the photovoltaic support. The photovoltaic supports located on the periphery are also fixed to the upper surface of the roll material through the connecting layer. In this way, in addition to further improving the installation firmness of the photovoltaic module, the weakening of the waterproof and heat-insulating integrated panel is also avoided after the photovoltaic module is installed.

For example, they may refer to a fixed connection, a detachable connection, or an integral part; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; they may refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

In the description of this application, it should be noted that the terms "upper", "lower", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0031] Due to the application of the above solution, this utility model has the following advantages and effects compared with the prior art:

[0032] The above-mentioned solution of this utility model addresses the problems of existing waterproof and thermal insulation integrated panels, such as the inability to install photovoltaic systems with flexible waterproof membranes, decreased waterproof performance, and fastener corrosion. It innovatively designs a prefabricated waterproof and thermal insulation integrated panel and a prefabricated roof photovoltaic system using this panel. This prefabricated waterproof and thermal insulation integrated panel includes, from bottom to top, a lower steel plate, a lower foam layer, an insulation layer, an upper foam layer, an upper steel plate, and a membrane layer.

[0050] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0051] This utility model aims to address the problems existing in existing waterproof and thermal insulation integrated panels, such as the inability to install photovoltaic systems with flexible waterproof membranes, reduced waterproof performance, and corrosion of fasteners 7. It innovatively designs a prefabricated waterproof and thermal insulation integrated panel and a prefabricated roof photovoltaic system using the waterproof and thermal insulation integrated panel, so that the waterproof and thermal insulation integrated panel can be equipped with photovoltaic modules 8, thereby improving waterproof performance and reducing safety hazards.

[0052] Example 1, as Figures 1 to 4 As shown in Embodiment 1 of this utility model, a prefabricated waterproof and thermal insulation integrated panel is provided. The waterproof and thermal insulation integrated panel includes, from bottom to top, a lower steel plate 1, a lower foaming layer 2, a thermal insulation layer 3, an upper foaming layer 4, an upper steel plate 5, and a roll material layer 6.

[0053] The lower steel plate 1 is a profiled steel plate with multiple profiled grooves 11 spaced apart along the laying length direction. The lower steel plate 1 has a lower overlapping edge 12 formed by a profiled groove 11 at the first end facing the laying length direction.

[0054] The lower foam layer 2 fills the forming groove 11 of the lower steel plate 1 and a distance above the surface.

[0055] The insulation layer 3 is composed of multiple insulation boards 31 arranged in an array on the upper surface of the lower foam layer 2.

[0056] The upper foaming layer 4 fills a distance above the surface of the insulation layer 3.

[0057] The upper steel plate 5 is laid on the upper surface of the upper foam layer 4.

[0058] The coil layer 6 is laminated to the upper surface of the upper steel plate 5, and the coil layer 6 has an upper lap edge 61 at the second end facing the laying length direction.

[0059] The integrated waterproof and thermal insulation panel is configured such that, in the state of assembly between adjacent integrated waterproof and thermal insulation panels, the upper overlapping edge 61 of the integrated waterproof and thermal insulation panel at the first end overlaps the roll layer 6 of the integrated waterproof and thermal insulation panel at the second end, and the lower overlapping edge 12 of the integrated waterproof and thermal insulation panel at the second end is assembled on the forming groove 11 of the integrated waterproof and thermal insulation panel at the second end.

[0060] Through the implementation of the above embodiments of this utility model, a three-layer waterproof system is formed by the lower steel plate 1, the upper steel plate 5, and the roll material layer 6. The composite application of the upper steel plate 5 and the roll material layer 6 makes it possible to install a photovoltaic system. Furthermore, the installation of the photovoltaic system will only damage one of the waterproof layers at the installation location, without affecting the other two layers of waterproofing. Therefore, the waterproofing performance is better. The lower foaming layer 2 and the upper foaming layer 4 set in this integrated waterproof and thermal insulation board allow the fasteners 7 to be placed inside the foaming agent and the thermal insulation layer 3 without penetrating the upper steel plate 5. After being filled with foaming agent, there will be no moisture corrosion, avoiding the hidden danger of reduced structural strength in the future.

[0061] In another embodiment of the present invention, the thickness of the lower steel plate 1 is 0.5-0.6 mm, the thickness of the upper steel plate 5 is 0.2-0.3 mm, and the thickness of the roll layer 6 is 1.2-2 mm. This reasonable thickness setting ensures good waterproofing performance for the three layers of waterproofing. The thickness settings of the lower steel plate 1 and the upper steel plate 5 balance weight and structural strength. Since the upper steel plate 5 is relatively thin, its position can be indicated by referring to [reference needed]. Figure 3 The enlarged schematic diagram shown.

[0062] In another embodiment of the present invention, a plurality of the insulation boards 31 are arranged vertically and tightly on the upper surface of the lower foaming layer 2 to improve the compressive strength of the insulation layer 3, thereby enhancing the overall strength of the entire waterproof and heat-insulating integrated board. The insulation board 31 is a polystyrene extruded board or a rock wool board.

[0063] In another embodiment of the present invention, the length of the upper overlap edge 61 of the roll layer 6 is greater than or equal to 80mm, thereby providing a sufficiently long upper overlap edge 61 for welding multiple waterproof and thermal insulation integrated panels subsequently, thus improving the waterproof effect. Specifically, the roll layer 6 is made of PVC roll material or TPO roll material, which has good waterproof effect and high strength.

[0064] In another embodiment of the present invention, the integrated waterproof and thermal insulation panel further includes a fastener 7 for fastening to the external rib 9. The fastener 7 extends upward from the location of the forming groove 11 through the lower foam layer 2, the thermal insulation layer 3, and the upper foam layer 4. The top of the fastener 7 abuts against the lower surface of the upper steel plate 5, but the fastener 7 does not penetrate. Furthermore, the lower steel plate 1 of one of the integrated waterproof and thermal insulation panels has two, three, four, five, or six forming grooves 11, which provides greater flexibility and can be selected according to the required assembly length, avoiding on-site cutting.

[0065] Example 2, as Figure 5 , Figure 6 As shown in Embodiment 2 of this utility model, a prefabricated roof photovoltaic system is proposed. The roof photovoltaic system includes a prefabricated waterproof and heat-insulating integrated panel as described in Embodiment 1 of this utility model, and a photovoltaic module 8 mounted on the waterproof and heat-insulating integrated panel.

[0066] In another embodiment of the second embodiment of this utility model, the photovoltaic module 8 includes a photovoltaic base 81 selectively disposed at a position corresponding to the position directly above the molding groove 11. The photovoltaic base 81 is provided with an upward-opening mounting hole, so as to enable the photovoltaic module 8 to be installed onto the waterproof and heat-insulating integrated board more quickly and firmly.

[0067] In another embodiment of the second embodiment of this utility model, the photovoltaic module 8 includes a photovoltaic panel 82 and a photovoltaic support 83. A plurality of photovoltaic supports 83 are provided at the bottom of the photovoltaic panel 82. The photovoltaic support 83 located in the middle is assembled into the photovoltaic base 81. A connecting layer 84 with the same material as the roll layer 6 is provided around the photovoltaic base 81 and the photovoltaic support 83. The photovoltaic supports 83 located on the periphery are also fixed to the upper surface of the roll layer 6 through the connecting layer 84. In this way, in addition to further improving the installation firmness of the photovoltaic module 8, it also avoids the weakening of the waterproof and heat-insulating integrated panel after the photovoltaic module 8 is installed.

The insulation layer 3 is composed of multiple insulation boards 31 arranged in a vertical array on the upper surface of the lower foamed layer 2. The insulation boards 31 are made of rock wool boards. The upper foamed layer 4 fills the upper surface of the insulation layer 3. The upper steel plate 5 is laid on the upper surface of the upper foamed layer 4. The thickness of the upper steel plate 5 is 0.2mm. The roll material layer 6 is laminated to the upper surface of the upper steel plate 5. The roll material layer 6 has an upper overlap edge 61 at the second end in the laying length direction. The thickness of the roll material layer 6 is 1.5mm, and the roll material layer 6 is made of PVC roll material. In the state of the adjacent waterproof and thermal insulation integrated panels being assembled, the upper overlap edge 61 of the waterproof and thermal insulation integrated panel at the first end overlaps the roll material layer 6 of the waterproof and thermal insulation integrated panel at the second end, and the lower overlap edge 12 of the waterproof and thermal insulation integrated panel at the second end is fitted onto the forming groove 11 of the waterproof and thermal insulation integrated panel at the second end. The nail (fastener 7) passes upward through the lower foam layer 2, the thermal insulation layer 3, and the upper foam layer 4 from the position of the forming groove 11, and the top of the fastener 7 abuts against the lower surface of the upper steel plate 5.

[0071] like Figure 5 , Figure 6 As shown, the photovoltaic base 81 is positioned directly above one of the forming grooves 11, and the lower surface of the photovoltaic base 81 is bonded to the upper surface of the upper steel plate 5. Multiple photovoltaic supports 83 are provided at the bottom of the photovoltaic panel 82, with the photovoltaic support 83 located in the middle being assembled into the photovoltaic base 81.
