Description

[Technical Field]

[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to a household photovoltaic power station. [Background Technology]

[0002] Currently, residential photovoltaic (PV) power stations typically employ two installation methods: rooftop installation and courtyard installation, corresponding to the installation of "residential sloping roof overhead PV brackets" and "residential courtyard PV brackets." The standard "residential sloping roof overhead PV bracket" can only be installed on a sloping roof with the roof tiles, while the standard "residential courtyard PV bracket" can only be installed within the farmer's courtyard. Given the current trend of villages with uniform house layouts (e.g., two-story sloping roof houses + terraces + courtyards), simply installing PV brackets on the sloping roof or solely on the courtyard limits the installed capacity. Farmers require integrated installation of the courtyard and sloping roof, while ensuring that the terrace space is not occupied by the brackets. [Utility Model Content]

[0003] To address the shortcomings of existing technologies, the technical problem to be solved by this utility model is to provide a support system for the integrated connection between a sloping roof and a courtyard, as well as a household photovoltaic power station, thereby solving the problem of integrated installation of a household photovoltaic power station in a courtyard and on a sloping roof.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A support system integrating a sloping roof and a courtyard includes a roof support installed on the roof of the house and a courtyard support located in the courtyard. A first sloping roof and a second sloping roof are correspondingly located on opposite sides of the roof. The roof support includes several lateral beams spaced laterally on the first sloping roof, several back braces spaced laterally on the second sloping roof, and short column support assemblies installed on the first and second sloping roofs to support the lateral beams and back braces. The back braces are correspondingly positioned to the sloping beams, with their upward-sloping ends connected to the beams. The sloping beams extend diagonally downwards along the first sloping roof to above the courtyard. The courtyard support includes columns installed in the courtyard, with the upper ends of the columns connected to the sloping beams. A support reinforcement structure is provided between the columns and the sloping beams and / or between the columns.

[0006] Preferably, the short column support assembly includes a short column and a roof short support member. The bottom of the roof short support member is supported on the first sloping roof and the second sloping roof. The short column and the roof short support member are fixed together by bolts. The upper end of the short column is fixed to the sloping beam and the back tie rod.

[0007] Preferably, the roof support also includes a wall support assembly fixed to the front wall and / or rear wall of the house, wherein the wall support assembly fixed to the front wall is connected to the inclined beam, and the wall support assembly fixed to the rear wall is connected to the rear tie rod.

[0008] Preferably, the wall support assembly includes an inclined support rod, a horizontal tie rod, and a first fixed seat. The first fixed seat is fixed to the wall. The upper end of the inclined support rod is connected to the inclined beam, and the lower end is connected to the first fixed seat. One end of the horizontal tie rod is connected to the inclined support rod, and the other end is connected to the first fixed seat.

[0009] Preferably, purlins are vertically and intersectingly fixed on the inclined beam, and transverse support rods are vertically and intersectingly fixed on the back tie rod.

[0010] Preferably, a ridge brace is provided between the back tie rod and the upward inclined end of the inclined beam.

[0011] Preferably, the support reinforcement structure includes a pressure bar parallel to the lower part of the inclined beam and positioned corresponding to the courtyard location, and a two-force bar between the inclined beam and the pressure bar.

[0012] Preferably, the lower level of the building has a protruding structural wall, and a horizontal bracing system is provided between the column and the protruding structural wall. The horizontal bracing system includes a horizontal bracing rod and a second fixing seat fixed to the protruding wall. One end of the horizontal bracing rod is connected to the column and the other end is connected to the second fixing seat.

[0013] Preferably, the support reinforcement structure includes a reinforcing diagonal brace disposed between the column and the inclined beam, and a reinforcing horizontal brace and / or a reinforcing diagonal brace connecting two adjacent columns.

[0014] In addition, this utility model also provides a residential photovoltaic power station, including the aforementioned support system.

[0015] The present invention adopts the above technical solution and has the following beneficial effects:

[0016] 1. This utility model combines a household sloping roof roof photovoltaic bracket with a household courtyard photovoltaic bracket to form a bracket system that integrates the sloping roof and the courtyard. It designs the roof bracket and the courtyard bracket as one unit, forming an integral slope above the first sloping roof and the courtyard to install photovoltaic modules, which can increase the number of photovoltaic modules installed and increase the power generation area.

[0017] In addition, for houses with balconies, no columns are installed above the balconies; instead, all columns are placed in the courtyard to ensure that the balconies are not occupied by the supports. This satisfies the requirement for integrated installation of photovoltaic panels on the courtyard and sloping roof, ensuring structural safety while preventing the balconies from being occupied by the supports and maintaining normal usability. It also increases the amount of photovoltaic panels that can be installed, achieving a combination of usability and aesthetics.

[0018] For courtyard supports, the structural stability of the courtyard supports can be ensured by the support and reinforcement structures between the columns and the inclined beams, as well as between the columns.

[0019] 2. Short column support assemblies are installed between the inclined beam and the rear tie rod and the roof. In addition, the roof support also includes wall support assemblies fixed to the front wall and / or rear wall of the building. This use of short column support assemblies avoids the roof leakage caused by using hook assemblies. The main fixing points can be fixed using wall support assemblies. The wall support assembly fixed to the front wall is connected to the inclined beam, ensuring reliable support for the cantilevered portion of the inclined beam near the wall. The wall support assembly fixed to the rear wall is connected to the rear tie rod, ensuring reliable support for the cantilevered portion of the rear tie rod near the wall.

[0020] 3. The purlins connect several diagonal beams into a whole, and the horizontal support rods connect several back tie rods into a whole, making the roof support structure more stable.

[0021] 4. A ridge brace is provided between the back tie rod and the upward inclined end of the inclined beam to ensure that the upward inclined end of the inclined beam is also reliably supported, thereby enhancing the overall structural stability of the roof support.

[0022] 5. The support reinforcement structure includes a lower compression member installed parallel to the inclined beam below the courtyard location, and a two-force member installed between the inclined beam and the lower compression member. The inclined beam acts as an upper compression member, and together with the lower compression member and the two-force member, forms a steel truss structure. The advantage of a truss is that the members mainly bear tension or compression, which can make full use of the material, save materials, and reduce the structural weight.

[0023] 6. The lower level of the house is provided with a protruding structural wall, and a horizontal bracing system is provided between the column and the protruding structural wall to further enhance the structural stability of the courtyard support.

[0024] 7. The support reinforcement structure includes a reinforcing diagonal brace located between the column and the inclined beam, as well as a reinforcing horizontal brace and / or a reinforcing diagonal brace connecting two adjacent columns, thereby further enhancing the structural stability of the courtyard support.

[0025] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. [Attached Image Description]

However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0038] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0039] The terminology used in this invention is for the purpose of describing specific embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "front," "rear," "longitudinal," and "lateral," which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0042] The residential photovoltaic power station in this embodiment is mainly designed for double-sloped roof scenarios, referring to... Figure 1 As shown, house 3 has a double-sloped roof. The roof has sloping roofs on both sides of the ridge, typically north and south (or front and back, since houses usually face south). Here, the south-facing sloping roof is designated as the first sloping roof 31, and the north-facing sloping roof as the second sloping roof 32. Additionally, this house type has a terrace 33 or other protruding structures on the lower level, with corresponding protruding structural walls. Therefore, this embodiment needs to address the issue of integrating the residential photovoltaic power station courtyard with the sloping roof, while ensuring that the terrace space is not occupied by the support structure.

[0043] like Figures 1 to 6As shown, the support system that integrates the sloping roof and the courtyard includes a roof support 1 installed on the roof of the house and a courtyard support 2 located in the courtyard. The roof support 1 includes a number of sloping beams 11 distributed laterally on the first sloping roof, a number of back tie rods 14 distributed laterally on the second sloping roof, and short column support assemblies 12 installed on the first and second sloping roofs to support the sloping beams and back tie rods. The back tie rods 14 are arranged in a corresponding lateral position to the sloping beams 11, and the upward diagonal ends of the back tie rods are connected to the sloping beams. The sloping beams 11 extend diagonally downward along the first sloping roof to the courtyard. The courtyard support 2 includes columns 21 installed in the courtyard. The upper ends of the columns are connected to the sloping beams. A support reinforcement structure is provided between the columns and the sloping beams, and between the columns.

[0044] The aforementioned integrated support system for the sloping roof and courtyard combines the roof support and courtyard support into one unit, forming a unified slope above the first sloping roof and courtyard for installing photovoltaic modules. This increases the number of photovoltaic modules installed and expands the power generation area.

[0045] In addition, for houses with balconies, no columns are installed above the balconies; instead, all columns are placed in the courtyard to ensure that the balconies are not occupied by the supports. This satisfies the requirement for integrated installation of photovoltaic panels on the courtyard and sloping roof, ensuring structural safety while preventing the balconies from being occupied by the supports and maintaining normal usability. It also increases the amount of photovoltaic panels that can be installed, achieving a combination of usability and aesthetics.

[0046] Because a support structure is installed between the columns and the inclined beams, the structural stability of the courtyard support is ensured.

[0047] It is understandable that the inclined beam can be a single, integrated structure, extending from the first sloping roof into the courtyard and covering the power station installation space within the courtyard, or it can be segmented, corresponding to roof support 1 and courtyard support 2, and connected as a whole by connectors, such as welding or bolting. The inclined beam is supported by columns and short columns to give the support structure a certain angle.

[0048] In addition, several purlins 15 are vertically and intersectingly fixed on the inclined beam 11, and the photovoltaic module 4 is installed on the purlins 15. Horizontal support rods 16 are vertically and intersectingly fixed on the rear tie rod 14. All of these can be connected by bolts. Thus, the purlins connect several inclined beams into a whole, and the horizontal support rods connect several rear tie rods into a whole, making the roof support structure more stable.

[0049] The short column support assembly rests on the roof tiles of the sloping roof, ultimately bearing the pressure of constant, active, and direct winds. Specifically, the short column support assembly 12 includes a short column 122 and a roof short support member 121. The bottom of the roof short support member is supported on the first and second sloping roof surfaces. The short column 122 and the roof short support member 121 are fixed together with bolts. The upper end of the short column is fixed to the inclined beam and the back tie rod. Specifically, the roof short support member 121 can be C-steel, and the short column 122 can be U-steel. A waterproof membrane 311 is installed on the sloping roof surface. One side of the C-steel is supported on the waterproof membrane, and the back is fixed to the short column 122 with bolts. Alternatively, on the second sloping roof surface, the roof short support member 121 can be C-steel, and the short column 122 can be a long bolt. The open side of the C-steel is supported on the sloping roof surface, and then the back is fixed to the lower end of the long bolt, and the upper end of the long bolt is fixed to the back tie rod.

[0050] Furthermore, the roof support 1 also includes a wall support assembly 13 fixed to the front wall and the rear wall of the house. The wall support assembly fixed to the front wall is connected to the inclined beam 11 to ensure that the cantilevered part of the inclined beam near the wall is reliably supported. The wall support assembly fixed to the rear wall is connected to the back tie rod 14 to ensure that the cantilevered part of the back tie rod near the wall is reliably supported.

[0051] like Figure 3 and Figure 4 The wall support assembly 13 includes an inclined support rod 131, a horizontal tie rod 132, and a first fixing seat 133. The first fixing seat 133 is fixed to the wall. The upper end of the inclined support rod 131 is connected to the inclined beam, and the lower end is connected to the first fixing seat. One end of the horizontal tie rod 132 is connected to the inclined support rod, and the other end is connected to the first fixing seat. The resulting wall triangular bracing system ultimately bears the pressure from constant, dynamic, and positive winds, as well as the tensile force generated by wind suction.

[0052] Furthermore, a ridge brace 17 is provided between the rear tie rod 14 and the upward-sloping end of the inclined beam 11. This adds a support point at the upward-sloping end of the inclined beam, enhancing the overall structural stability of the roof support.

[0053] To create a terrace, the house features a protruding structural wall. A horizontal bracing system 25 is installed between the column and the protruding structural wall. The horizontal bracing system 25 includes a horizontal tie rod 251 and a second fixing seat 252 fixed to the protruding wall. One end of the horizontal tie rod is connected to the column, and the other end is connected to the second fixing seat. This further enhances the structural stability of the courtyard support.

[0054] like Figure 1As shown, in some embodiments, the support reinforcement structure includes a lower pressure bar 22 parallel to the bottom of the inclined beam and corresponding to the courtyard position, and a two-force bar 23 between the inclined beam and the lower pressure bar. The inclined beam, equivalent to the upper pressure bar, together with the lower pressure bar and the two-force bar, forms a steel truss structure. The advantage of a truss is that the members mainly bear tension or compression, which can make full use of the material, save materials, and reduce the structural weight. In addition, diagonal bracing bars 24 are provided between the column and the inclined beam for reinforcement.

[0055] In the above embodiments, the main components are connected by welding, such as between the inclined beam and the back tie rod, between the inclined beam and the back tie rod and the short column, between the column and the inclined beam, between the column and the horizontal tie rod, between the column and the diagonal brace, between the two-force member and the inclined beam and the lower pressure member, etc.

[0056] like Figure 7 As shown, in some embodiments, the house may not have a terrace, and therefore no protruding structural wall is required on the lower level. Additionally, the rooftop photovoltaic system is installed in an overhead manner, the height of the short column support components can be increased, and a reinforcing beam can be added below the inclined beam. The front end of the reinforcing beam connects to the column, the rear end connects to the back tie rod, and the middle connects to the short column support components. No wall support components are installed between the front wall of the house and the adjacent row of columns.

[0057] In addition, the support reinforcement structure includes a reinforcing diagonal brace 28 disposed between the column 21 and the inclined beam 11, and a reinforcing horizontal brace 27 connecting two adjacent columns and the reinforcing diagonal brace 28. In this embodiment, a hinge 26 can be provided between the reinforcing diagonal brace 28 and the column and inclined beam. The hinge is welded to the column and inclined beam, and the reinforcing diagonal brace 28 is hinged to the hinge 26.

[0058] like Figure 8 As shown, two reinforcing diagonal braces 28 can be arranged in an X-shape between the two horizontal columns, and the X-shaped intersections can be welded or bolted together. When the column height is low, a single-layer X-shaped reinforcement structure can be installed, such as... Figure 9 As shown, when the column height is relatively high, a double-layer X-shaped reinforcement structure can be installed. Furthermore, the intersections of the X-shapes are fixed together by welding or bolting.

[0059] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
