DETAILED DESCRIPTION

[0032] In order for a building to utilize solar energy, it is usually necessary to install photovoltaic panels on the roof of the building through a bracket assembly to form a photovoltaic roof.

[0034] Since the metal shaft 3' and the TPO plate 1' in the above-mentioned support are mainly made of two different materials and assembled, after the metal shaft 3' is vertically penetrated through the building roof, the air outside the building roof and the air inside the building roof will generate a cold bridge phenomenon at the metal shaft 3' of the support due to the temperature difference to form condensed water. The condensed water will pass through the building roof along the metal shaft 3' and enter the building, thereby soaking the user's belongings in the house, which will correspondingly reduce the user experience.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0039] In order to solve the above technical problems, Figure 2 As shown, an embodiment of the utility model provides an anti-cold bridge support, including a support plate 1 and a connector 2, the support plate 1 includes a sealing sheet 11 and a wrapping portion 12, the wrapping portion 12 at least wraps around a portion of the circumferential side of the connector 2, the sealing sheet 11 is arranged around the periphery of the wrapping portion 12, the sealing sheet 11 is used to seal and connect the building roof 5; the wrapping portion 12 and the connector 2 are used to connect the photovoltaic panel through the support frame 4 of the bracket assembly; the connector 2 is used to be connected to the screw 3 of the bracket assembly penetrating the building roof 5.

[0040] It should be noted that the sealing sheet 11 is arranged around the outer edge of the wrapping portion 12, and it can also be understood that the wrapping portion 12 can be located in the middle area of ​​the sealing sheet 11. The sealing sheet 11 can be sealed and connected to the building roof in the following manner. For example, the sealing sheet 11 can be made of waterproof material, so the sealing sheet 11 can be fused and welded to the surface of the building roof 5 by a hot air gun to achieve a sealed connection between the sealing sheet 11 and the building roof 5.

[0041] The wrapping unit 12 is Figure 2 The surface facing the positive direction of the Z axis in the coordinate system is the top surface of the wrapping portion 12, and the screw 3 is Figure 2 The end on the positive side of the Z axis in the coordinate system is the top of the screw 3. Figure 2 As shown, the top end of the screw rod 3 is vertically penetrated through the building roof 5 and connected to the connecting member 2 , and the top end of the screw rod 3 is located in the connecting member 2 , so that the support plate 1 and the connecting member 2 are fixed to the building roof 5 through the screw rod 3 .

[0042] The wrapping portion 12 at least wraps around a portion of the circumferential side surface of the connector 2. It can be understood that the wrapping portion 12 can wrap around the entire connector 2, or the wrapping portion 12 wraps around a portion of the circumferential side surface of the connector 2, such as the upper structure.

[0043] In this embodiment, the support plate 1 mainly includes a sealing sheet 11 and a wrapping portion 12. Since the wrapping portion 12 wraps around at least a portion of the connecting member 2, and the sealing sheet 11 is arranged around the periphery of the wrapping portion 12, the support plate 1 and the connecting member 2 can form an integral structure. The sealing sheet 11 can be sealed and connected to the building roof 5, so that the anti-cold bridge support with a larger surface and an integral structure can be sealed and stably installed on the building roof 5.

[0044] The top surface of the wrapping portion 12 can be higher than the top surface of the sealing sheet 11, and the sealing sheet 11 is fitted and installed on the building roof 5, so that the wrapping portion 12 wrapped around the connecting piece 2 is also higher than the building roof 5, and the support frame 4 can be installed on the wrapping portion 12 higher than the building roof 5, so that there is a certain height space between the support frame 4 and the building roof 5, and the photovoltaic panel can be arranged above the support frame 4 of the bracket assembly. When the wrapping portion 12 and the connecting piece 2 are assembled with the support frame 4, not only the assembly convenience of the photovoltaic panel and the support frame 4 can be improved, but also because the wrapping portion 12 is at least wrapped around part of the circumferential side surface of the connecting piece 2, the connecting piece 2 and the wrapping portion 12 wrapped around the connecting piece 2 can improve the vertical support stiffness of the photovoltaic panel, and correspondingly improve the installation stability of the photovoltaic panel.

[0045] Since the wrapping portion 12 at least wraps around part of the circumferential side of the connector 2, and the top end of the screw rod 3 of the bracket assembly is passed through the building roof 5 and then connected to the connector 2, so that the top end of the screw rod 3 is in the connector 2, and the portion below the top end of the screw rod 3 is in the building roof 5, so that the entire screw rod 3 is not exposed to the natural environment outside the building roof, that is, the support plate 1 and the connector 2 sealed with the building roof 5 effectively reduce or even prevent the temperature conduction between the air outside the building roof 5 and the screw rod 3 passed through the building roof 5, so as to prevent the cold bridge phenomenon, and accordingly avoid the generation of condensation water at the screw rod 3, so as to protect the items of users in the building.

[0046] In one embodiment of the utility model, the connecting member 2 includes a connecting block 21, the wrapping portion 12 is wrapped around the top surface and the peripheral side surface of the connecting block 21, and the top end of the screw rod 3 extends into the connecting block 21 from the bottom surface of the connecting block 21.

[0047] It should be noted that the connecting member 2 includes a connecting block 21. When the wrapping portion 12 is wrapped around the top surface and the peripheral side surfaces of the connecting block 21, most of the structures of the connecting block 21, such as the top surface and the peripheral outer side surfaces, are located inside the wrapping portion 12. When the top of the screw 3 is passed through the building roof 5 and connected to the connecting block 21, not only can the connection between the screw 3 and the connecting block 21 be achieved, but also because the top end of the screw 3 is located inside the connecting block 21 and does not extend beyond the connecting block 21, the position below the top end of the screw 3 is located inside the building roof 5, which can also prevent cooling from occurring and avoid the generation of condensed water.

[0048] In this embodiment, an internal thread can be opened in the connecting block 21, and an external thread can be set at the top of the screw rod 3, so that the top of the screw rod 3 is passed through the building roof 5 and threadedly connected with the internal thread of the connecting block 21, so as to achieve a stable connection between the screw rod 3 and the connecting block 21.

[0049] Specifically, the connecting block 21 may be a polygonal column structure, so that when the screw rod 3 is connected to the connecting block 21 , the connecting block 21 is prevented from rotating in the wrapping portion 12 , thereby improving the assembly convenience and stability of the screw rod 3 and the connecting block 21 .

[0050] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the connecting member 2 further includes a connecting column 22, one end of which is connected to the connecting block 21, and the connecting column 22 is used to be inserted into the building roof 5;

[0051] The connection block 21 and the connection column 22 are respectively provided with internal threads threadedly connected to the screw rod 3 .

[0052] It should be noted that the wrapping portion 12 can be wrapped around the connecting block 21, and the connecting column 22 can be arranged at the lower end of the connecting block 21, and the connecting column 22 can extend downward beyond the wrapping portion 12 and penetrate the portion of the building roof 5, which is equivalent to increasing the vertical length of the entire connecting piece 2. When vertically arranged and connected internal threads are respectively opened in the connecting block 21 and the connecting column 22, it can be understood that the length of the internal thread of the connecting piece 2 is increased. The top end of the screw rod 3 is penetrated through the building roof 5 and connected to the internal thread of the connecting piece 2, thereby further improving the connection stability and reliability of the screw rod 3 and the connecting piece 2 by increasing the connection length of the screw rod 3 and the connecting piece 2.

[0053] The connecting column 22 is used to be inserted into the building roof 5, which means that the length of the connecting column 22 is less than the thickness of the building roof 5, so that the connecting column 22 cannot completely penetrate the building roof 5. Figure 2 The dimension in the Z-axis direction of the coordinate system is the length of the connecting column 22, and the building roof 5 is Figure 2 The dimension in the Z-axis direction of the central coordinate system is the thickness of the building roof 5 .

[0054] The connecting column 22 and the connecting block 21 can be an integrally formed structure, thereby effectively improving the mechanical strength of the connecting piece 2; the connecting column 22 can be a cylindrical structure, and before the connecting column 22 is inserted into the building roof 5, a circular hole can be opened at the corresponding position of the building roof 5 and the anti-cold bridge support by an electric tool, so that it is not only convenient for the connecting column 22 to be inserted into the part of the building roof 5 (i.e., inserted into the circular hole), but also convenient for the internal thread to be opened in the connecting column 22, and the screw 3 and the internal thread of the connecting column 22 are quickly assembled. Among them, the connecting piece 2 can be tapped by drilling equipment such as a CNC lathe to form the internal thread.

[0055] In addition, the support plate 1 and the connecting member 2 of the anti-cold bridge support can be assembled in the following manner. For example, after the connecting column 22 and the connecting block 21 are processed to form the connecting member 2, a waterproof material such as a TPO material can be injected into the surface of the connecting member 2 at a certain position by injection molding. Figure 5 As shown, the structure wrapped around the connection block 21 may be the wrapping portion 12 of the support plate 1, and the structure outside the wrapping portion 12 may be the sealing sheet 11 of the support plate 1; wherein the wrapping portion 12 matches the shape of the connection block 21.

[0056] Among them, the outermost part of the sealing sheet 11 of the support plate 1 can be a circular structure, which makes it easier and more efficient during injection molding, and is more convenient when sealing and welding with the building roof 5 through a hot air gun, so as to improve the installation efficiency of the anti-cold bridge support and the building roof 5.

[0057] In one embodiment of the present invention, Figure 4 As shown, a rounded structure 23 is provided at the connection between the connection column 22 and the connection block 21 .

[0058] It should be noted that a rounded structure 23 is provided at the outer edge of the connection between the connecting column 22 and the connecting block 21 to effectively avoid stress concentration at the connection between the connecting column 22 and the connecting block 21 and reduce the risk of breakage of the connecting column 22 and the connecting block 21.

[0059] In one embodiment of the present invention, Figure 3 As shown, the support plate 1 further includes a blocking portion 13 , which is wrapped around the bottom surface of the connecting block 21 . The blocking portion 13 is provided with a through hole for the connecting column 22 to pass through, and the size of the through hole is smaller than the size of the connecting block 21 .

[0060] It should be noted that the connection between the sealing sheet 11 and the wrapping portion 12 extends in the direction of the connecting column 22 to form the blocking portion 13. It can be understood that the blocking portion 13 is located below the connecting block 21 and the wrapping portion 12, wherein the wrapping portion 12 is wrapped around the surrounding side walls and the top surface of the connecting block 21, and the blocking portion 13 covers the bottom surface of the connecting block 21. Since the connecting column 22 is arranged below the connecting block 21, the blocking portion 13 reserves a through hole at the connecting column 22 to avoid the connecting column 22, or to facilitate the connecting column 22 to pass through the through hole and then pass downward to the building roof 5.

[0061] Since the size of the perforation is smaller than that of the connecting block 21, when the top end of the screw 3 is passed through the building roof 5 and assembled and tightened with the connecting column 22 of the connecting piece 2 and the connecting block 21, the blocking portion 13 can effectively prevent the connecting block 21 from detaching from the wrapping portion 12, thereby further improving the assembly stability of the screw 3 and the anti-cold bridge support.

[0062] In an embodiment of the present invention, the connecting member 2 is made of a material with a thermal conductivity lower than 10 W / (m·k).

[0063] It should be noted that in the above-mentioned prior art, the metal shaft can be a steel shaft or an aluminum shaft. Since the thermal conductivity of steel is usually 40-50W / (m·k), and the thermal conductivity of aluminum is usually 200W / (m·k), the thermal conductivity is better, so when the metal shaft passes through the building roof 5, the top and bottom ends of the metal shaft respectively contact the external and internal air of the building roof 5, and it is easy for cooling to occur at the metal shaft and generate condensed water; therefore, in this embodiment, the connecting member 2 is limited to be made of a material with a thermal conductivity of less than 10W / (m·k), which can effectively reduce or even avoid preventing the temperature conduction between the air outside the building roof 5 and the screw 3 penetrating the building roof 5, so as to prevent the cold bridge phenomenon, and correspondingly avoid the generation of condensed water at the screw 3, so as to protect the items of users in the building.

[0064] In an embodiment of the present invention, the connecting member 2 is made of any one of nylon, a composite material of polypropylene + glass fiber and a composite material of thermoplastic polyester + glass fiber; and / or the supporting plate 1 is made of a waterproof material.

[0065] It should be noted that the connector 2 is made of nylon, and the thermal conductivity of nylon is generally 0.25-0.510W / (m·k), so that the temperature conduction between the air outside the building roof 5 and the air inside the building roof 5 can be better prevented, and the cooling phenomenon can be further prevented; and the pull-out force of the connector 2 made of nylon is generally greater than 7000N, and it has good tensile properties. After being connected and assembled with the screw 3, the safety performance of use can be well guaranteed. Furthermore, the heat deformation temperature of the connector 2 made of nylon is above 240°C, which can withstand a certain high temperature environment and is very suitable for use under outdoor roof conditions.

[0066] The composite material of polypropylene + glass fiber refers to a polypropylene material with glass fiber added; and the composite material of thermoplastic polyester + glass fiber refers to a composite material composed of thermoplastic polyester such as polybutylene terephthalate and glass fiber in a certain proportion.

[0067] The support plate 1 is made of waterproof material, which can effectively prevent rainwater or condensed water outside the building roof 5 from entering the building from the connection between the support plate 1 and the building roof 5. For example, the waterproof material can be TPO material, where TPO material refers to thermoplastic polyolefin material, which is an elastomeric material composed of two components, rubber and polyolefin, combining the properties of rubber and thermoplastic plastics, and can show high elasticity of rubber at room temperature, and can be plasticized and formed at high temperature.

[0068] Combination Figure 6 As shown, another embodiment of the utility model provides a bracket assembly, including a screw rod 3, a nut member 6, a support frame 4 and the anti-cold bridge support as described in the above embodiment, the screw rod 3 is passed through the building roof 5 and is threadedly connected to the connecting member 2 above the building roof 5, and the nut member 6 is sleeved on the screw rod 3 and is located below the building roof 5.

[0069] It should be noted that the support frame 4 can be installed above the wrapping portion 12. The top end of the screw rod 3 is passed through the building roof 5 and is threadedly connected to the connector 2, and the bottom end of the screw rod 3 can be connected through the nut member 6, and the nut member 6 is located below the building roof 5, so that the anti-cold bridge support is fixed to the building roof 5 through the screw rod 3 between the nut member 6 and the connector 2, thereby improving the assembly stability of the two.

[0070] The nut member 6 may be a rivet nut or a common nut.

[0071] In one embodiment of the present invention, Figure 6 and Figure 7As shown, the bracket assembly also includes a fastener 7, the support frame 4 includes a support angle steel 41 and a connecting frame 42, the connecting frame 42 includes two connecting plates, the two connecting plates are respectively arranged on the opposite sides of the wrapping portion 12 of the anti-cold bridge support, and the connecting plate is tightly arranged with the wrapping portion 12, the fastener 7 is passed through the connecting plate, the wrapping portion 12 and the connector 2 of the anti-cold bridge support to fasten the connecting frame 42 and the anti-cold bridge support; the support angle steel 41 is arranged above the connecting frame 42 and connected to the connecting frame 42, and the upper end of the support angle steel 41 is used to connect the photovoltaic panel.

[0072] It should be noted that the connecting frame 42 can be a door-type structure, so the connecting member 2 can have two connecting plates, and bolt holes can be provided on the wrapping portion 12 and the connecting block 21. When the connecting member 2 is assembled with the anti-cold bridge support, the two connecting plates are respectively installed on the opposite sides of the wrapping portion 12, and then the fasteners 7 are passed through the bolt holes of the connecting plates and the wrapping portion 12 and the connecting block 21, so as to increase the connection area with the anti-cold bridge support through the two connecting plates, and correspondingly improve the assembly stability of the connecting frame 42 and the anti-cold bridge support. Specifically, the fastener 7 can be a nut structure, which is not specifically limited here.

[0073] By installing the supporting angle steel 41 above the connecting frame 42 and fixing the supporting angle steel 41 to the connecting frame 42, the photovoltaic panel can be installed on the supporting angle steel 41, so that the photovoltaic panel can be stably supported from below by the supporting angle steel 41. There is no need to add parts such as guide rails in the prior art, which reduces the installation of parts, thereby reducing the cost of the overall bracket assembly and improving installation efficiency.

[0074] Specifically, the support angle steel 41 and the connecting frame 42 can be an integrated structure, thereby effectively improving the mechanical strength of the support frame 4, so as to correspondingly improve the installation stability of the photovoltaic panel. The number of the support angle steel 41 is at least one, for example, when the number of the support angle steel 41 is two, the two support angle steels 41 can be arranged opposite to each other, thereby increasing the connection area between the support angle steel 41 and the photovoltaic panel, so as to further improve the installation stability of the photovoltaic panel.

[0075] Combination Figure 7 As shown, another embodiment of the utility model provides a photovoltaic roof, including a building roof 5, a photovoltaic panel and the bracket assembly as described in the above embodiment, the building roof 5 includes a stacked waterproof layer 51, thermal insulation cotton 52 and a roof inner panel 53, the sealing sheet 11 of the anti-cold bridge support is sealed and connected to the waterproof layer 51; the photovoltaic panel is installed on the support frame 4 of the bracket assembly.
