Description

Technical Field

[0001] This invention relates to the field of rooftop color steel photovoltaic bracket technology, and in particular to a rooftop color steel photovoltaic bracket and its connection method. Background Technology

[0002] With the rapid development of green energy, photovoltaic power generation systems are increasingly widely used in the building sector. Among them, rooftop corrugated steel tile photovoltaic support systems are favored due to their advantages such as not damaging the original roof structure and convenient installation. Traditional corrugated steel tile roof photovoltaic supports are usually fixed to the upright locking edge of the roof with clamps and rely on a guide rail system to support and fix the photovoltaic modules.

[0003] Traditional upright locking clamps are mostly asymmetrically designed, which can easily become tilted during installation and under load due to instability of the center of gravity. This affects the locking effect of the clamp and the flatness of the subsequent installation of the guide rail and photovoltaic modules. Furthermore, the connection between the guide rails usually relies on simple connectors, which are often not strong enough and can easily become weak points in the structure under load, posing a safety hazard. Moreover, the edge clamps used to secure photovoltaic modules are usually only compatible with modules of a single thickness, lacking compatibility, limiting their application range and reducing installation efficiency. The traditional locking structure of the clamp and guide rail has a relatively short clamp length. In the vertical direction, the clamp is usually positioned between two adjacent photovoltaic modules. During installation, the torque control of the electric wrench requires extremely precise control. Slight carelessness may cause the guide rail to deform. In addition, the thinness of the clamp itself results in a short engagement length with the bolt. Similarly, when using an electric wrench, if the torque control is not correct, the connection between the bolt and the clamp will loosen. The construction is difficult and inefficient. In view of this, in-depth research was conducted to address the above problems, which led to this case. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a roof-mounted color steel photovoltaic bracket and connection method. This invention addresses the issues of traditional upright locking clamps, which are often asymmetrically designed and prone to tilting during installation and under load due to instability, affecting the clamp's locking effect and the flatness of the subsequent installation of the guide rails and photovoltaic modules. Furthermore, the connection between guide rails typically relies on simple connectors, which are often insufficient in strength and can easily become weak points in the structure under load, posing safety hazards. Additionally, the edge clamps used to secure photovoltaic modules are usually only compatible with modules of a single thickness, lacking compatibility, limiting their application range, and reducing installation efficiency. Traditional locking structures with clamps and guide rails have relatively short clamp lengths. Vertically, the clamps are usually positioned between two adjacent photovoltaic modules, requiring extremely precise torque control with an electric wrench during installation. Slight errors can lead to guide rail deformation. Moreover, the thinness of the clamps results in a short engagement length with the bolts. Similarly, when using an electric wrench, incorrect torque control can cause the bolt and clamp connection to loosen, leading to high construction difficulty and low efficiency.

[0005] The technical solution of the present invention to achieve the above objectives is as follows: a roof color steel photovoltaic bracket, including roof color steel tiles, the roof color steel tiles including multiple roof covering panels, two adjacent roof covering panels are connected by a standing seam structure, and a balanced standing seam clamp is provided on the standing seam structure;

The extension plate and the top plate are symmetrically arranged with the first central upright plate as the center. The extension plate and the top plate are movably attached to the bottom horizontal surface. The upper wall surfaces of the extension plate and the top plate are on the same horizontal plane. A countersunk threaded hole is provided in the center of the extension plate.

[0010] Preferably, the clamping fixture includes a bending clamping frame, a clamping plate extending vertically from the top of the bending clamping frame, a thinning support plate extending from one end of the clamping plate in the same direction as the extension plate, a support threaded hole coaxial with the countersunk threaded hole on the thinning support plate, and a support bolt being threadedly inserted into the countersunk threaded hole and the support threaded hole.

[0011] Preferably, each of the threaded components includes a second connecting bolt, which is movably inserted through the clamping plate and the first central upright plate.

[0013] Preferably, the pressing component includes an insert plate, the lower wall of which has a slot that matches the locking strip, a vertical plate extending upward from one end of the insert plate, and a pressure plate extending parallel to the insert plate from one end of the vertical plate. The pressure plate is movably attached to the upper wall of the photovoltaic module. The insert plate has through holes that match the thin and thick through holes. The distance between the thin bottom support plate and the thin limiting plate, and the distance between the thick bottom support plate and the thick limiting plate are the same as the thickness of the insert plate.

[0014] Preferably, the high-strength locking block includes a main body block, a thickened block at the lower end of the main body block, and the central portions of the main body block and the thickened block are threadedly fitted onto one end of a locking bolt. Top-fitting blocks are provided on both sides of the main body block. Each top-fitting block includes a top extended surface, and the edge of the top extended surface has a locking curved surface that matches the top and bottom thickened edges. The edge of the locking curved surface extends downwards to form a closed inclined surface, the bottom of which is closed to the bottom of the main body block. A hollow groove is formed in the center of the top-fitting block. The cross-sectional area of ​​the thickened block is not greater than the sum of the cross-sectional areas of the two hollow grooves. The top extended surface is on the same plane as the upper wall of the main body block. The front and rear end faces of both the main body block and the top-fitting block are aligned with the front and rear end faces of the main body block.

[0015] A connection method includes the following steps:

[0016] Step 1: Pre-tighten the balanced standing seam clamp and clamp it onto the standing seam structure of the roof corrugated steel sheet to be installed. Then tighten the balanced standing seam clamp to fix it on the roof corrugated steel sheet. Finally, use support studs on the top of the balanced standing seam clamp to support and connect the extension plate and the thinning support plate in the balanced standing seam clamp. Tighten the top surface of the support studs so that they do not protrude from the top of the balanced standing seam clamp. Install and fix multiple balanced standing seam clamps in this way at the required intervals.

[0017] Step 2: Place the guide rail flat on the top surface of the fixed balanced upright locking clamp, and use high-strength clamps and locking bolts to connect and fix the bottom surface of the guide rail to the top surface of the balanced upright locking clamp.

[0018] Step 3: Insert the reinforcing connector into both sides of the control rail and tighten it with the other control rail that needs to be connected by mounting the first connecting bolts on both sides.

[0019] Step 4: Place the photovoltaic modules flat on the guide rail in the required order. Then, use high-strength clamps and locking bolts to install the compatible side pressure blocks on the outside of the photovoltaic modules. During installation, adjust the direction of the compatible side pressure blocks as needed to adapt to photovoltaic modules of different thicknesses. Use high-strength clamps and locking bolts to press the middle pressure block and photovoltaic modules together between two adjacent photovoltaic modules. The installation is now complete.

[0020] The rooftop color steel photovoltaic bracket and connection method manufactured using the technical solution of the present invention have the following beneficial effects:

[0021] 1. The balanced upright locking clamp has a top plate and an extension plate symmetrically arranged around the first central upright plate, which makes the clamp bear the force evenly on both sides when clamping the upright locking structure, reducing the risk of tilting during installation and use, and ensuring the support quality of the guide rail.

[0022] 2. The guide rail adopts a double-sided hook structure design, and reinforcing connectors can be installed on both sides to ensure connection strength. The reinforcing connectors have a structure design with a right-angle extension frame, which improves their own strength, even exceeding the strength of the guide rail itself, forming an equal-strength connection system. This ensures the connection quality at the guide rail connection and improves the safety factor of the entire photovoltaic support system under large load conditions.

[0023] 3. The compatible edge clamping block is equipped with both thin and thick clamping structures, which can simultaneously fix two photovoltaic modules of different thicknesses, expanding the scope of application, reducing the types of accessories, and improving installation efficiency;

[0024] 4. The high-strength clamp has increased its length, which is greater than the distance between two photovoltaic modules. In the vertical direction, the high-strength clamp has an overlapping area with the two photovoltaic modules, increasing the contact area with the guide rail. This allows the force of the electric wrench to be transferred from the guide rail to the photovoltaic module frame without shearing or deforming the guide rail itself. During construction, there is no need to deliberately control the wrench force, which facilitates installation, speeds up construction, and improves efficiency. Furthermore, the thickened block design increases the engagement length with the locking bolt, eliminating the need for precise control of the electric wrench torque during installation and preventing the locking bolt from loosening from the high-strength clamp. This makes operation simpler and improves construction speed. Attached Figure Description

[0045] Example 1:

[0046] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-11 As shown, a type of roof-mounted color steel photovoltaic bracket.

[0047] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0048] A rooftop color steel photovoltaic support includes a roof color steel tile 1, the roof color steel tile 1 includes multiple roof covering panels 11, and two adjacent roof covering panels 11 are connected by a vertical locking structure 12, and a balanced vertical locking clamp 5 is provided on the vertical locking structure 12.

[0049] It should be noted that two adjacent roof covering panels 11 are connected by a standing seam structure 12 to form a roof corrugated steel tile 1, which is installed on the roof of the building.

[0050] Specifically, the top of the balanced upright locking clamp 5 is symmetrically arranged with the upright locking structure 12 as the center. A guide rail assembly is movably installed on the balanced upright locking clamp 5. The guide rail assembly consists of multiple opposing guide rails 3. Reinforcing connectors 4 are movably installed on both sides of the connection between two adjacent opposing guide rails 3 through the first connecting bolts 2. Multiple photovoltaic modules are movably attached to the multiple opposing guide rails 3. An inverted V-shaped middle pressure block 9 is movably installed between two adjacent photovoltaic modules. A compatible edge pressure block 6 is movably arranged on the edge of each photovoltaic module. The balanced upright locking clamp 5, the inverted V-shaped middle pressure block 9 and the compatible edge pressure block 6 are all connected to the opposing guide rails 3 through high-strength locking blocks 7. Locking bolts 8 are installed on the high-strength locking blocks 7.

[0051] It should be noted that the balanced upright locking clamp 5, through its symmetrical structural design, maintains a balance of weight on both sides, reducing the degree of tilting when installed on the upright locking structure 12. This facilitates the locking and fixing of the balanced upright locking clamp 5. When the guide rail 3 is installed on the balanced upright locking clamp 5, it ensures the support quality of the guide rail 3 and the subsequent installation quality of the photovoltaic modules. The guide rail 3 adopts a symmetrical design, and both sides can be fitted with reinforcing connectors 4 via the first connecting bolts 2, ensuring the strength of the connection between the two guide rails 3. The reinforcing connector 4, through its structural design, has improved strength compared to traditionally shaped connectors, ensuring the overall strength of the photovoltaic bracket. The inverted V-shaped pressure block 9 is used for pressing. Two adjacent photovoltaic modules are secured by a compatible edge clamping block 6. The compatible edge clamping block 6 is suitable for photovoltaic modules of various thicknesses and can fix two photovoltaic modules of different thicknesses, thus expanding the applicability of the edge clamping block and improving the overall installation efficiency. The balanced upright locking clamp 5, the inverted V-shaped middle clamping block 9, and the compatible edge clamping block 6 are all connected to the guide rail 3 by a high-strength clamping block 7 and a locking bolt 8. The high-strength clamping block 7 increases the engagement length with the locking bolt 8. When the electric wrench rotates the locking bolt 8, there is no need to deliberately control the wrench force, making the operation simple and thus speeding up the construction speed and improving work efficiency. At the same time, through structural design and the extension of its length, the connection strength is guaranteed while achieving lightweight.

[0052] Specifically, the guide rail 3 includes a horizontal bar 31, and the two ends of the horizontal bar 31 are symmetrically provided with side hook structures. The side hook structure includes a side vertical surface 32. The top of the side vertical surface 32 extends horizontally with a top horizontal surface 33. The top horizontal surface 33 located outside the horizontal bar 31 extends downward with a top vertical flange 34. The bottom of the side vertical surface 32 extends horizontally with a bottom horizontal surface 35. The bottom horizontal surface 35 located outside the horizontal bar 31 extends upward with a bottom vertical flange 36. The top horizontal surface 33 located inside the horizontal bar 31 is provided with a top thickened edge 37. The bottom horizontal surface 35 located inside the horizontal bar 31 is provided with a bottom thickened edge 38.

[0053] It should be noted that the horizontal bar 31 is used to connect the side hook structure on both sides and provide lateral support. The side facade 32 is set at 90 degrees with the horizontal bar 31 and provides longitudinal support. The top horizontal surface 33 and the bottom horizontal surface 35 can be matched with the roof covering panel 11 or photovoltaic modules.

[0054] Specifically, the reinforcing connector 4 includes a central facade 41. The two ends of the central facade 41 extend inclinedly towards the side facade 32, with an upper support leg 42 and a lower support leg 43. One end of the upper support leg 42 extends upward with an upper retaining edge 44, and one end of the lower support leg 43 extends downward with a lower retaining edge 45. The upper retaining edge 44 is movably attached to the side facade 32, the top horizontal surface 33, and the top vertical flange 34. The lower retaining edge 45 is movably attached to the side facade 32, the bottom horizontal surface 35, and the bottom vertical flange 36. Right-angle extension brackets 46 are provided at both the upper and lower ends of the central facade 41. A boss 47 is provided on the side of the central facade 41 near the side facade 32. The first connecting bolt 2 is movably inserted into the boss 47 and the central facade 41 through a thread. One end of the first connecting bolt 2 is movably attached to the side facade 32.

[0055] It should be noted that the reinforcing connector 4 is installed at the connection point of the two mating guide rails 3 via the first connecting bolt 2. The right-angle extension bracket 46 is used to expand the area of ​​the central facade 41, increase the strength of the central facade 41, and prevent deformation of the central facade 41. When it is necessary to connect the two sections of the mating guide rail 3, the upper retaining edge 44 slides into the area enclosed by the top vertical flange 34, the top horizontal surface 33, and the side facade 32. At the same time, the lower retaining edge 45 slides into the area enclosed by the bottom vertical flange 36, the bottom horizontal surface 35, and the side facade 32. In the area enclosed by the side facades 32, the top horizontal surface 33 and the bottom horizontal surface 35 restrict the reinforcing connector 4 from moving vertically, and the top vertical flange 34 and the bottom vertical flange 36 restrict the reinforcing connector 4 from moving horizontally. By setting side hook structures on both sides of the horizontal bar 31, the reinforcing connector 4 can be installed on both sides of the control rail 3. For the form of photovoltaic brackets laid flat on the roof color steel tile 1, the connection strength at the connection of the two control rails 3 is improved, the load requirements are met, and the safety factor is improved.

[0056] Specifically, the balanced upright locking clamp 5 includes a support clamp and a clamping clamp. The support clamp and the clamping clamp are installed on the upright locking structure 12 through multiple threaded components. The support clamp includes a first central upright plate 501. A bottom plate 502 extends laterally from the bottom of the first central upright plate 501. A top plate 503 extends from the top of the first central upright plate 501 in the same direction as the bottom plate 502. A large arc connecting surface 514 is provided between the top plate 503 and the first central upright plate 501. An extension plate 504 extends laterally from the end of the top plate 503 that is opposite to the bottom plate 502. The extension plate 504 and the top plate 503 are symmetrically arranged with the first central upright plate 501 as the center. The extension plate 504 and the top plate 503 are movably attached to the bottom horizontal surface 35. The upper wall surfaces of the extension plate 504 and the top plate 503 are on the same horizontal plane. A countersunk threaded hole 505 is opened in the center of the extension plate 504.

[0057] Specifically, the clamping fixture includes a bending clamping frame 506, a clamping plate 507 extending vertically from the top of the bending clamping frame 506, a thinning support plate 508 extending from one end of the clamping plate 507 in the same direction as the extension plate 504, a support threaded hole 509 coaxially formed on the thinning support plate 508 and the countersunk threaded hole 505, and a support bolt 510 being threadedly inserted into the countersunk threaded hole 505 and the support threaded hole 509.

[0058] It should be noted that the support clamp and clamping clamp are pre-tightened by multiple threaded components and clamped onto the upright locking structure 12. Then, the multiple threaded components are tightened to fix the support clamp and clamping clamp onto the corrugated steel roof. At this time, the first central upright plate 501 is attached to the side wall of the upright locking structure 12, and the bottom plate 502 is attached to the roof covering panel 11. Since the top plate 503 and extension plate 504 are symmetrically arranged on both sides of the first central upright plate 501, there is a balancing effect on both sides, reducing the degree of tilting when the upright locking clamp is installed on the upright locking structure 12, facilitating the locking and fixing of the balanced upright locking clamp 5. When the guide rail 3 is installed on the balanced upright locking clamp 5, the top plate 503 and extension plate 504 can be balanced on the guide rail 3, ensuring the support quality of the guide rail 3 and the subsequent installation quality of the photovoltaic modules. After tightening the multiple threaded components... After fixing the support fixture and clamping fixture onto the upright locking structure 12, the support bolt 510 is threaded into the countersunk threaded hole 505 and the support threaded hole 509. Since no clamping fixture needs to be installed between the top plate 503 and the central vertical plate, a large arc connecting surface 514 can be set to ensure the connection strength between the top plate 503 and the central vertical plate. However, a clamping fixture needs to be installed between the first central vertical plate 501 and the extension plate 504. Therefore, the support bolt 510 is set at the connection position between the first central vertical plate 501 and the extension plate 504. Through the thread engagement of the support bolt 510 with the countersunk threaded hole 505 and the support threaded hole 509, a support relationship exists between the extension plate 504 and the thinned support plate 508, ensuring the strength of the extension plate 504. The countersunk threaded hole 505 is used to accommodate the head of the support bolt 510, so that the top surface of the support bolt 510 does not protrude from the top of the extension plate 504.

[0059] Specifically, each threaded assembly includes a second connecting bolt 511, which is movably inserted through the clamping plate 507 and the first central upright plate 501. A connecting nut 512 is movably fitted onto the second connecting bolt 511 via threads. Both the top plate 503 and the extension plate 504 are provided with elongated through holes 513.

[0060] It should be noted that the connection between the support fixture and the clamping fixture is achieved through the cooperation of the second connecting bolt 511 and the connecting nut 512, and the elongated through hole 513 is used for the through passage of the locking bolt 8;

[0061] Specifically, the compatible edge pressure block 6 includes a support 61, on which a pressure member 62 is movably mounted;

[0062] It should be noted that the compatible edge pressure block 6 is installed on the control rail 3 through the support 61, and the pressure piece 62 is movably inserted into the support 61 to fix the edge of the photovoltaic module.

[0063] Specifically, the support 61 includes a second central upright plate 611, and thin-pressed structure and thick-pressed structure are respectively provided on both sides of the second central upright plate 611.

[0064] It should be noted that photovoltaic modules come in various thicknesses. Taking 33mm and 35mm thicknesses as examples, a thin-pressed structure is matched with a 33mm thick photovoltaic module, and a thick-pressed structure is matched with a 35mm thick photovoltaic module. In actual production, the size design of the thin-pressed and thick-pressed structures includes, but is not limited to, matching photovoltaic modules with 33mm and 35mm thicknesses. When the thickness of the photovoltaic module is 33mm, the pressing component 62 is installed on the thin-pressed structure. When the thickness of the photovoltaic module is 35mm, the pressing component 62 is installed on the thick-pressed structure. The thin-pressed and thick-pressed structures can be symmetrically arranged with the central upright plate as the center, which can simultaneously fix two photovoltaic modules with different or the same thickness, improving adaptability and installation efficiency.

[0065] Specifically, the thin-pressed structure includes a thin bottom support plate 612, which is horizontally disposed on one side wall of the second central upright plate 611. A thin limiting plate 613 is disposed on one side wall of the second central upright plate 611 above the thin bottom support plate 612. Thin through holes 614 are coaxially formed on both the thin bottom support plate 612 and the thin limiting plate 613. The thick-pressed structure includes a thick bottom support plate 615, which is horizontally disposed on the other side of the second central upright plate 611. On the side wall, the thick bottom support plate 615 is located between the thin bottom support plate 612 and the thin limiting plate 613. On the other side wall of the second central upright plate 611, above the thick bottom support plate 615, a thick limiting plate 616 is provided. The thick limiting plate 616 is located above the thin limiting plate 613. Both the thick bottom support plate 615 and the thick limiting plate 616 have thick through holes 617 coaxially formed. Both the thin bottom support plate 612 and the thick bottom support plate 615 have retaining strips 618 on their upper walls.

[0066] It should be noted that when the pressure member 62 is installed on the thin pressure structure, the pressure member 62 is pushed laterally between the thin bottom support plate 612 and the thin limiting plate 613. The thin bottom support plate 612 is used to support the pressure member 62, and the thin limiting plate 613 is used to prevent the pressure member 62 from moving longitudinally in the thin bottom support plate 612. When the pressure member 62 is installed on the thick pressure structure, the pressure member 62 is pushed laterally between the thick bottom support plate 615 and the thick limiting plate 616. The thick bottom support plate 615 is used to support the pressure member 62, and the thick limiting plate 616 is used to prevent the pressure member 62 from moving longitudinally in the thick bottom support plate 615.

[0067] Specifically, the pressure component 62 includes an insertion plate 621. The lower wall of the insertion plate 621 has a slot 622 that matches the slot strip 618. One end of the insertion plate 621 extends upward with a vertical plate 623. One end of the vertical plate 623 extends parallel to the insertion plate 621 with a pressure plate 624. The pressure plate 624 is movably attached to the upper wall of the photovoltaic module. The insertion plate 621 has through holes 625 that match the thin through hole 614 and the thick through hole 617. The distance between the thin bottom support plate 612 and the thin limiting plate 613, and the distance between the thick bottom support plate 615 and the thick limiting plate 616 are the same as the thickness of the insertion plate 621.

[0068] It should be noted that the insertion plate 621 is inserted between the thin bottom support plate 612 and the thin limiting plate 613 and between the thick bottom support plate 615 and the thick limiting plate 616 through the matching of the slot 622 and the clip 618. After the insertion plate 621 is installed in place between the thin bottom support plate 612 and the thin limiting plate 613, the through hole 625 and the thin through hole 614 are coaxially arranged. After the insertion plate 621 is installed in place between the thick bottom support plate 615 and the thick limiting plate 616, the through hole 625 and the thick through hole 617 are coaxially arranged for inserting bolts. The pressure plate 624 is pressed against the upper wall surface of the edge of the photovoltaic module, and the vertical plate 623 is attached to the side wall surface of the edge of the photovoltaic module. The support 61 and the pressure plate 62 are fixed by the high-strength clip 7 that matches the guide rail 3, thereby realizing the fixation of the photovoltaic module.

[0069] Specifically, the high-strength locking block 7 includes a main block 71, with a thickened block 72 at the lower end of the main block 71. The center of the main block 71 and the thickened block 72 are threadedly fitted onto one end of the locking bolt 8. Top-fitting blocks 73 are provided on both sides of the main block 71. The top-fitting block 73 includes a top extended surface 731, and the edge of the top extended surface 731 is provided with a locking curved surface 732. The locking curved surface 732 matches the top thickened edge 37 and the bottom thickened edge 38. The edge of the locking curved surface 732 extends downwards to form a closed inclined surface 733. The bottom of the closed inclined surface 733 is closed with the bottom of the main block 71. A hollow groove 74 is provided in the center of the top-fitting block 73. The cross-sectional area of ​​the thickened block 72 is not greater than the sum of the cross-sectional areas of the two hollow grooves 74. The top extended surface 731 and the upper wall of the main block 71 are on the same plane. The front and rear end faces of the main block 71 and the top-fitting block 73 are aligned with the front and rear end faces of the main block 71.

[0070] It should be noted that when installing the high-strength clamping block 7, the high-strength clamping block 7 is inserted horizontally into the guide rail 3. Its top extended surface 731 and the engaging curved surface 732 match the guide rail 3. The thickened block 72 thickens the main block 71, increasing the length of the high-strength clamping block 7 itself, that is, increasing the engagement length between the locking bolt 8 and the high-strength clamping block 7. When the electric wrench rotates the locking bolt 8, there is no need to deliberately control the wrench force, making the operation simple, thereby speeding up the construction and improving work efficiency. A hollow groove 74 is set inside the top engaging block 73 to reduce the overall weight of the high-strength clamping block 7. Through the design of the closed inclined surface 733, the high-strength clamping block 7 of this technical solution has narrower inclined surfaces on both sides compared with the traditional high-strength clamping block 7, while ensuring normal installation. This can reduce the amount of material used by 4%, achieving lightweighting, which is convenient for use when laying photovoltaic brackets on the roof color steel tile 1, reducing the load on the roof color steel tile 1 and preventing damage to the roof color steel tile 1.

[0071] More specifically, existing clamps are relatively small in length and are usually positioned vertically between two photovoltaic modules. During construction, the torque of the electric wrench needs to be very precise. If the wrench force is slightly too strong, the guide rail may be sheared and deformed. In this technical solution, the length of the high-strength clamp 7 set between two adjacent photovoltaic modules is greater than the distance between the two photovoltaic modules. In the vertical direction, the high-strength clamp 7 has an overlapping area with the two photovoltaic modules, which transmits the force of the electric wrench from the control guide rail 3 to the frame of the photovoltaic module. This ensures that the control guide rail 3 itself will not be sheared and deformed. During construction, there is no need to deliberately control the wrench force, which facilitates installation and speeds up construction and improves efficiency.

[0072] More specifically, simulation tests of this system revealed that the section modulus of a traditional single-sided connecting guide rail is 1243 mm². 3 The cross-sectional area is 158 mm². 2 In this technical solution, the section modulus of the guide rail 3 is 1498 mm. 3 The cross-sectional area is 168 mm². 2 It has greater strength;

[0073] More specifically, simulation tests of this system revealed that the section modulus of the traditional connector is 472 mm². 3 In this technical solution, the section modulus of the reinforcing connector 4 is 1780 mm². 3 It has greater strength, and since the strength of the reinforcing connector 4 is greater than the strength of the guide rail 3 itself, it conforms to the equal strength connection system.

[0074] Example 2:

[0075] A connection method includes the following steps:

[0076] Step 1: Pre-tighten the balanced standing seam clamp 5 and clamp it onto the standing seam structure 12 of the roof corrugated steel sheet 1 to be installed. Then, tighten the balanced standing seam clamp 5 to fix it onto the roof corrugated steel sheet 1. Finally, use support studs to support and connect the extension plate 504 and the thinning support plate 508 in the balanced standing seam clamp 5 at the top. Tighten the top surface of the support studs so that they do not protrude from the top of the balanced standing seam clamp 5. Install and fix multiple balanced standing seam clamps 5 at the required spacing in this manner.

[0077] Step 2: Place the guide rail 3 flat on the top surface of the fixed balanced upright locking clamp 5, and use the high-strength clamp 7 and locking bolt 8 to connect and fix the bottom surface of the guide rail 3 to the top surface of the balanced upright locking clamp 5.

[0078] Step 3: Insert the reinforcing connector 4 into both sides of the control rail 3, and connect it to the other control rail 3 that needs to be connected by tightening it with the first connecting bolts 2 installed on both sides.

[0079] Step 4: Place the photovoltaic modules flat on the guide rail in the required order. Then, use the high-strength clamping block 7 and locking bolt 8 to install the compatible side pressure block 6 on the outside of the photovoltaic modules. During installation, adjust the direction of the compatible side pressure block 6 as needed to adapt to photovoltaic modules of different thicknesses. Use the high-strength clamping block 7 and locking bolt 8 to press the middle pressure block 9 between two adjacent photovoltaic modules. The installation is now complete.

Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
