[0054] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0055] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0057] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0058] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0059] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a photovoltaic component, including a photovoltaic module 4 and a color steel tile 3. The photovoltaic module 4 is installed on the color steel tile 3, and can convert solar energy into electrical energy for powering various devices in the building. The color steel tile 3 includes a male rib 31, a female rib 32 and an angle portion 33. The angle portion 33 is located between the male rib 31 and the female rib 32. The angle portion 33 is raised in the height direction, which can increase the wind resistance of the color steel tile 3. A bottom plate is arranged between the male rib 31 and the angle portion 33, and a bottom plate is also arranged between the female rib 32 and the bottom plate. The male rib 31 and the bottom plate, and the female rib 32 and the bottom plate are connected by a bending portion 34; the bending portion 34 includes a first bending section 341 and a second bending section 342. One end of the first bending section 341 is connected to the male rib 31 or the female rib 32, and the other end extends toward the direction close to the angle portion 33. The first bending section 341 is connected to the bottom plate by a second bending section 342 extending obliquely. The edge of the photovoltaic module 4 can be bonded and fixed to the corner portion 33, or the edge of the photovoltaic module 4 can be bonded and fixed to the first bending section 341. In a possible embodiment, the photovoltaic component also includes a clamp 5, which is fixed to the male rib 31, the female rib 32 of the color steel tile 3 or to the corner portion 33, so that the photovoltaic module 4 can be fixed to the color steel tile 3 through the clamp 5. When the photovoltaic component is located in an area with a high wind speed, the roof of the color steel tile 3 will be affected by the wind load, causing a difference in the air flow rate on the upper and lower surfaces of the roof of the color steel tile 3, resulting in a pressure difference between the upper and lower surfaces of the roof of the color steel tile 3. When the air flow rate on the upper surface of the roof of the color steel tile 3 is significantly greater than the air flow rate on the lower surface of the roof of the color steel tile 3, the pressure below the roof of the color steel tile 3 is greater than that above, so that the color steel tile 3 is subjected to a pressure perpendicular to the roof of the color steel tile 3 and outward. The photovoltaic component also includes a middle bracket, which is connected to the corner portion 33 in the color steel tile 3, supporting the color steel tile 3 to avoid the possibility of deformation of the color steel tile 3 due to uneven roof. The photovoltaic component also includes a support 10, one end of the support 10 is between the male rib 31 and the female rib 32 of the adjacent color steel tile 3, and is fixedly connected by locking, and the other end of the support 10 is fixedly connected to the purlin on the building body, thereby fixing the photovoltaic module 4 on the building body, and can also reduce the possibility of safety accidents caused by the color steel tile 3 being dislodged by force. The building body here can be a roof, ground, wall and other structures, and the specific type of the building body is not particularly limited in the embodiment of the present application.

[0060] The cells in the photovoltaic module 4 are used to convert solar energy into electrical energy. The present application does not limit the structure of the cells. The types of cells include but are not limited to passivated emitter rear contact cells (Passivated Emitter Rear Cell, PERC), tunnel oxide passivated contact cells (Tunnel Oxide Passivated Contact, TOPCON), heterojunction cells (Heterojunction with Intrinsic Thin-film, HJT), back contact cells (Back Contact, BC), perovskite cells (Perovskite Solar Cells, PSC), etc.

[0061] For PERC cells, along the thickness direction, PERC cells include front surface metal silver electrode, front surface silicon nitride passivation layer, phosphorus layer emitter, P-type base silicon layer, local aluminum back field, metal aluminum back electrode, back passivation layer (Al2O3 / SiNx). PERC cells use a passivation film to passivate the back, replacing the full aluminum back field, enhancing the internal back reflection of light in the silicon base, reducing the recombination rate on the back, and increasing the efficiency of the cell by 0.5%-1%.

[0062] For TOPCon cells, along the thickness direction, TOPCon cells include metal silver electrodes, front surface silicon nitride passivation layers, boron-doped emitters, N-type base silicon layers, diffused doping layers, ultra-thin silicon oxide, doped polysilicon, silicon nitride, and metal silver electrodes. The back of the cell is composed of a layer of ultra-thin silicon oxide (1nm to 2nm) and a layer of phosphorus-doped microcrystalline amorphous mixed Si film, which together form a passivation contact structure. This structure can block the recombination of minority carrier holes and increase the open circuit voltage and short circuit current of the cell. The ultra-thin oxide layer allows majority electrons to tunnel into the polysilicon layer while blocking the recombination of minority carrier holes. The good passivation effect of ultra-thin silicon oxide and heavily doped silicon film causes the energy band on the silicon wafer surface to bend, thereby forming a field passivation effect, greatly increasing the probability of electron tunneling, reducing contact resistance, and increasing the open circuit voltage and short circuit current of the cell, thereby improving the cell conversion efficiency.

[0063] For HJT cells, along the thickness direction, the HJT cells include a front low-temperature silver electrode, a front conductive film, an N-type amorphous silicon film, an intrinsic amorphous silicon film, an N-type base silicon layer, an intrinsic amorphous silicon film, a P-type amorphous silicon film, a back conductive film, and a back low-temperature silver electrode.

[0064] For IBC cells, along the thickness direction, IBC cells include silicon nitride anti-layer, N+ front surface field, N-type base silicon layer, P+ emitter, N+ back field, aluminum oxide passivation layer, silicon nitride anti-reflection layer, and metal silver electrode. IBC cells use ion implantation technology to obtain P and N regions with good uniformity and precisely controllable junction depth. There is no grid line blocking on the front of the cell, which can eliminate the shading current loss of the metal electrode and achieve the maximum utilization of incident photons. The short-circuit current can be increased by about 7% compared with conventional solar cells; due to the back contact structure, there is no need to consider the grid line blocking problem, and the grid line ratio can be appropriately widened, thereby reducing the series resistance and having a high fill factor; the surface passivation and surface light trapping structure can be optimized to obtain a lower front surface recombination rate and surface reflection.

[0065] For perovskite cells, along the thickness direction, the perovskite cell includes substrate material, conductive film, electron transport layer (titanium dioxide), perovskite absorption layer (hole transport layer), and metal cathode. Perovskite materials have a high light absorption coefficient and a long carrier diffusion distance. After the photons absorbed by the perovskite material are converted into electrons, they are easily collected by the electrode with low loss, so they can generate higher photoelectric voltage and current, making perovskite show higher photoelectric conversion efficiency.

[0066] like Figure 3 As shown, the embodiment of the present application provides a support 10 for connecting the purlins and the color steel tile 3 in the photovoltaic component. The support 10 includes a base 1 and a connector 2. The base 1 includes a mounting plate 11 and a fixing plate 12. The fixing plate 12 is located on one side of the mounting plate 11 and is used to connect with the purlin. The connector 2 is installed on the mounting plate 11 and is used to connect with the color steel tile 3. The mounting plate 11 extends along the height direction Z of the support 10, and the fixing plate 12 extends along the thickness direction Y of the support 10, so that the base 1 is L-shaped. A mounting groove 111 is provided on one side of the mounting plate 11 away from the fixing plate 12. A mounting beam 112 is provided in the mounting groove 111. The mounting beam 112 extends along the width direction X of the support 10, so that the two ends of the mounting beam 112 are respectively connected to the two side walls of the mounting groove 111. The connector 2 includes a mounting hole 21, and the mounting beam 112 extends into the mounting hole 21, so that the connector 2 is sleeved in the mounting beam 112 through the mounting hole 21.

[0067] The connector 2 is sleeved on the mounting beam 112 through the mounting hole 21. The two ends of the mounting beam 112 are connected to the two side walls of the mounting groove 111. The two side walls of the mounting groove 111 can limit the relative position of the connector 2 and the base 1 along the width direction X of the support 10, thereby improving the reliability of the connection between the connector 2 and the base 1 and reducing the possibility of the connector 2 falling off from the end of the mounting beam 112. Under the action of a high-velocity wind field, after the surface of the color steel tile 3 is subjected to wind load, a pressure difference will be generated between the upper and lower surfaces, so that the color steel tile 3 is subjected to a force in the direction away from the base 1. The color steel tile 3 is connected to the connector 2, and the color steel tile 3 will exert a force on the connector 2 in the direction away from the base 1. The connector 2 has a mounting hole 21, so that the connector 2 is sleeved on the mounting beam 112 of the base 1. When the connector 2 is subjected to a force in the direction away from the base 1, the possibility of the connector 2 being separated from the base 1 can be reduced, which is conducive to improving the reliability of the connection between the color steel tile 3 and the purlin, and reducing the possibility of the color steel tile 3 falling off and causing a safety accident.

[0068] like Figure 4 As shown, in a possible embodiment, along the height direction Z of the support 10 , first reinforcement members 113 are provided on both sides of the mounting beam 112 .

[0069] The first reinforcement member 113 can be formed integrally with the mounting beam 112, and is a flange of the mounting beam 112 bent along the thickness direction Y of the bracket, and a bending section is also provided at the end of the flange. The bending sections in the first reinforcement member 113 on both sides of the mounting beam 112 are bent in a direction close to each other, which can improve the strength of the mounting beam 112 and reduce the possibility of deformation of the mounting beam 112. At the same time, the height of the first reinforcement member 113 protruding from the surface of the mounting beam 112 can also be reduced. The connecting member 2 is sleeved on the mounting beam 112, which reduces the possibility of interference between the first reinforcement member 113 and the inner wall of the mounting hole 21. The first reinforcement member 113 extends along the width direction X of the support 10. Along the extension direction of the mounting beam 112, the side edges of the mounting beam 112 are connected to the first reinforcement member 113, so that the first reinforcement member 113 can strengthen the strength of the mounting beam 112. When the connecting member 2 is subjected to a force in a direction away from the base 1, the possibility of deformation of the mounting beam 112 can be reduced, which is beneficial to improving the reliability of the connection between the color steel tile 3 and the support 10.

[0070] like Figure 4 As shown, in a possible embodiment, a first reinforcement member 113 is also provided on one side of the mounting groove 111 close to the fixing plate 12 , where the first reinforcement member 113 may be a flange provided on the bottom wall of the mounting groove 111 , and also extends along the width direction X of the support 10 .

[0071] The first reinforcing member 113 disposed on the bottom wall of the mounting groove 111 can be integrally formed with the mounting plate 11, and is formed by bending the bottom wall of the mounting groove 111 along the thickness direction Y of the support 10, thereby improving the strength of the position where the mounting groove 111 is disposed in the mounting plate 11, and reducing the possibility of deformation of the mounting plate 11. The fixing plate 12 can be an integrally formed structure with the mounting plate 11, and has an angle with the mounting plate 11 to form an L-shaped structure, which can further improve the strength of the side where the mounting plate 11 is connected to the fixing plate 12, reduce the possibility of deformation of the mounting plate 11, and help improve the reliability of the color steel tile 3 after being connected to the support 10.

[0072] like Figure 4 As shown, in a possible embodiment, second reinforcement members 114 are provided on both sides of the mounting plate 11 along the width direction X of the support 10, and the second reinforcement members 114 extend along the height direction Z of the support 10, so that the two side edges of the mounting plate 11 are provided with second reinforcement members 114 of the same height.

[0073] The second reinforcement 114 is integrally formed with the mounting plate 11. The second reinforcement 114 can be a flange bent along the thickness direction Y of the support 10 on the two side surfaces in the width direction X of the mounting plate 11. When the mounting plate 11 is subjected to external force, the possibility of deformation of the two side surfaces in the width direction X of the mounting plate 11 can be reduced, thereby strengthening the strength of the mounting plate 11 and facilitating the reliability of the connection between the color steel tile 3 and the support 10.

[0074] like Figure 4 As shown, in a possible embodiment, the mounting plate 11 includes a third reinforcement member 115 , and the third reinforcement member 115 is located at an end of the mounting plate 11 away from the fixing plate 12 .

[0075] The third reinforcement 115 is integrally formed with the mounting plate 11. The third reinforcement 115 can be a flange bent along the thickness direction Y of the support 10 at one end of the mounting plate 11 away from the fixed plate 12. When the mounting plate 11 is subjected to external force, the possibility of deformation of the side of the mounting plate 11 away from the fixed plate 12 can be reduced, thereby improving the strength of the mounting plate 11.

[0076] The fixing plate 12, the second reinforcement 114 and the third reinforcement 115 are all bent along the thickness direction Y of the support 10. The fixing plate 12 is bent toward one side of the mounting plate 11, and the second reinforcement 114 and the third reinforcement 115 are bent toward the other side of the mounting plate 11. When installing the self-tapping screws, the possibility of the fixing hole 121 being blocked by the second reinforcement 114 and the third reinforcement 115 is reduced, which makes it easier for the staff to install the support 10 on the purlin.

[0077] like Figure 4As shown, in a possible embodiment, the fixing plate 12 includes a fixing hole 121, and the self-tapping screw passes through the fixing hole 121 to connect the base 1 to the purlin. The spacing between the fixing hole 121 and the mounting plate 11 is 9 mm to 13 mm.

[0078] The base 1 is connected to the purlin by self-tapping screws. If the spacing between the fixing hole 121 and the mounting plate 11 is less than 9 mm, the end of the self-tapping screw may interfere with the mounting plate 11, making it inconvenient to install the self-tapping screw. When the color steel tile 3 is subjected to a large external force, the mounting plate 11 connected to the color steel tile 3 is also subjected to a force in a direction away from the fixing plate 12. If the spacing between the fixing hole 121 and the mounting plate 11 is greater than 13 mm, the spacing between the connection point where the fixing plate 12 and the purlin are connected by the self-tapping screws and the mounting plate 11 is large, the torque is large, and the fixing plate 12 is prone to deformation. Therefore, the spacing between the fixing hole 121 and the mounting plate 11 can be 9 mm, 11 mm, 13 mm, etc., preferably 11 mm. Compared with the prior art, the spacing between the fixing hole 121 and the mounting plate 11 is reduced, which can reduce the possibility of deformation of the fixing plate 12.

[0079] like Figure 4 As shown, in a possible embodiment, a plurality of fourth reinforcement members 116 are provided between the mounting plate 11 and the fixing plate 12. The mounting plate 11 and the fixing plate 12 may be an integrally formed structure, and a protrusion as the fourth reinforcement member 116 is provided at the position where the mounting plate 11 and the fixing plate 12 are connected, which can limit the angle between the mounting plate 11 and the fixing plate 12, reduce the possibility of deformation at the connection position of the mounting plate 11 and the fixing plate 12, and help improve the bearing capacity of the base 1 against external forces.

[0080] Along the width direction X of the support 10, a plurality of fourth reinforcement members 116 are arranged at intervals to improve the connection strength between the mounting plate 11 and the fixing plate 12. The fixing hole 121 is arranged on the fixing plate 12, and the spacing between the fixing hole 121 and the mounting plate 11 is small. Along the width direction X of the support 10, a plurality of fourth reinforcement members 116 and the fixing hole 121 are staggered, which can reduce the interference between the fourth reinforcement members 116 and the fixing hole 121, and facilitate the installation of self-tapping screws.

[0081] like Figure 4 As shown, in a possible embodiment, the base 1 may be made of a steel plate through machining, and the thickness of the steel plate used for machining the base 1 is 1 mm to 2 mm.

[0082] If the thickness of the steel plate is less than 1mm, its strength is relatively low, and it is still easy to deform when the base 1 is subjected to external force, causing the color steel tile 3 to detach from the purlin under the action of high-velocity wind field, which is easy to cause safety accidents. The base 1 includes multiple reinforcements to reduce the possibility of deformation of the base 1. If the thickness of the steel plate is greater than 2mm, it will lead to waste of steel and increase the production cost of the base 1. Therefore, the thickness of the steel plate can be 1mm, 1.5mm, 2mm, etc., preferably 1.5mm, so that the base 1 has sufficient strength, which can reduce the possibility of deformation of the base 1 and reduce the production cost of the base 1.

[0083] like Figure 3 and Figure 5 As shown, in a possible embodiment, the connecting member 2 is sleeved on the base 1 through the mounting hole 21. Along the width direction X of the support 10, the width of the side of the connecting member 2 where the mounting hole 21 is provided is smaller than the width of the mounting beam 112, so that there is a gap between the connecting member 2 and the two side walls of the mounting groove 111, thereby enabling the connecting member 2 to move along the mounting beam 112.

[0084] When the photovoltaic component is installed in an area with a large temperature difference between day and night, the color steel tile 3 is affected by the temperature, and the color steel tile 3 expands and contracts due to heat and cold, which will cause the color steel tile 3 to deform. The end of the connector 2 away from the base 1 is connected to the color steel tile 3. When the color steel tile 3 is deformed, the connector 2 will be driven to move. There is a gap between the connector 2 and the side wall of the installation groove 111, so that the connector 2 can move with the color steel tile 3 relative to the base 1, which can reduce the possibility of damage to the support 10 when the color steel tile 3 is deformed, which is conducive to improving the service life of the support 10.

[0085] like Figure 5 , Figure 6 and Figure 7 As shown, in a possible embodiment, the connector 2 includes a mounting portion 24, a first connecting portion 22, and a second connecting portion 23. The connector 2 can be formed by bending a steel plate. Before bending, the first connecting portion 22 and the second connecting portion 23 are respectively located at two ends of the mounting portion 24 in the length direction. After bending, the mounting portion 24 encloses the mounting hole 21. The first connecting portion 22 and the second connecting portion 23 are located on the same side of the mounting portion 24, so that the first connecting portion 22 and the second connecting portion 23 can be connected to the color steel tile 3 at the same time. The overlapping position of the first connecting portion 22 and the second connecting portion 23 can be fixed by bonding or welding, so that the connector 2 is sleeved on the mounting beam 112, reducing the possibility of the connector 2 falling off.

[0086] Along the width direction X of the connecting member 2, the first connecting portion 22 and the second connecting portion 23 are inclined in different directions, the angle between the first connecting portion 22 and the mounting portion 24 is α, 120°≤α≤140°, and the angle between the second connecting portion 23 and the mounting portion 24 is β, 120°≤β≤140°.

[0087] The first connection part 22 and the second connection part 23 are inclined in different directions, so that the end of the first connection part 22 and the end of the second connection part 23 after the connection part 2 is bent are staggered, which can increase the connection area between the connection part 2 and the color steel tile 3, and thus improve the reliability of the connection between the connection part 2 and the color steel tile 3. If the angle between the first connection part 22 and the mounting part 24 and the angle between the second connection part 23 and the mounting part 24 are both less than 120°, the distance between the first connection part 22 and the second connection part 23 is large after the connection part 2 is bent, and the first connection part 22 and the second connection part 23 may also interfere with the base 1, reducing the range of movement of the connection part 2 relative to the base 1. When the color steel tile 3 is affected by temperature and expands and contracts, the connection part 2 cannot move with the expansion and contraction of the color steel tile 3, which is easy to cause damage to the support 10. If the angle α between the first connection part 22 and the mounting part 24 and the angle β between the second connection part 23 and the mounting part 24 are both greater than 140°, after the connection member 2 is bent, the end of the first connection part 22 and the end of the second connection part 23 may overlap, and the reliability of the connection between the connection member 2 and the color steel tile 3 is reduced along the width direction X of the support 10. The angle α between the first connection part 22 and the mounting part 24 can be 120°, 130°, 140°, etc., preferably 125°, and the angle β between the second connection part 23 and the mounting part 24 can be 120°, 130°, 140°, etc., preferably 125°, so that after the connection member 2 is bent, the first connection part 22 and the second connection part 23 can be staggered along the width direction X of the support 10, thereby increasing the connection area between the connection member 2 and the color steel tile 3.

[0088] In a possible embodiment, the thickness of the steel plate used to make the connector 2 is 0.4 mm to 0.8 mm, specifically 0.4 mm, 0.6 mm, 0.8 mm, etc., preferably 0.6 mm. If the thickness of the steel plate is less than 0.4 mm, the strength of the connector 2 is low, and the color steel tile 3 is easy to detach from the connector 2 under the action of a high-speed wind field, causing property losses and safety accidents. If the thickness of the steel plate is greater than 0.8 mm, the production cost of the connector 2 will be increased.

[0089] like Figure 5 and Figure 6 As shown, in a possible embodiment, the first connection portion 22 and the second connection portion 23 are arranged at intervals along the width direction X of the support 10. Along the height direction Z of the support 10, the first connection portion 22 and the second connection portion 23 are connected to the color steel tile 3 away from the side of the base 1.

[0090] The connecting piece 2 is connected to the color steel tile 3 through the first connecting part 22 and the second connecting part 23, which can increase the connection area between the connecting piece 2 and the color steel tile 3, reduce the possibility of the color steel tile 3 being forced out under the action of a high-speed wind field, and improve the reliability of the color steel tile 3 after being connected to the support 10.

[0091] like Figure 5 and Figure 7 As shown, in a possible embodiment, the first connection portion 22 and the second connection portion 23 both include a first bending portion 221 and a second bending portion 222, which are used to connect with the color steel tile 3. The first bending portion 221 is bent along the thickness direction Y of the support 10, and the second bending portion 222 is located at the end of the first bending portion 221 and is bent toward a side close to the mounting portion 24.

[0092] The male rib 31 of one of the adjacent color steel tiles 3 and the female rib 32 of the other are connected to the same support 10. When the support 10, the purlin and the color steel tile 3 are connected, the male rib 31 of one color steel tile 3 is first matched with the connecting piece 2 in the support 10, the base 1 of the support 10 is in contact with the purlin, and the relative position of the support 10 and the purlin is adjusted, and then the support 10 is fixed to the purlin by self-tapping screws, and then the female rib 32 in the other color steel tile 3 is buckled into the connecting piece 2 and the male rib 31. When the connector 2 is locked with the color steel tile 3, the male rib 31 and the female rib 32 are respectively located on both sides of the thickness direction of the connector 2, and overlap with the first bending portion 221 and the second bending portion 222, and then the second bending portion 222 is bent, and at the same time, the male rib 31 and the female rib 32 are bent along with the second bending portion 222, and then the first bending portion 221 is bent, so that the male rib 31, the female rib 32 and the connector 2 are wound and connected, which can improve the reliability of the color steel tile 3 after being connected to the connector 2, and reduce the possibility of the color steel tile 3 being separated from the support 10. The first bending portion 221 and the second bending portion 222 are arranged at the end of the connector 2, so that the connector 2 is convenient for bending and winding when the color steel tile 3 and the connector 2 are fixed.

[0093] like Figure 5 and Figure 7 As shown, in a possible embodiment, the angle between the first bending portion 221 and the second bending portion 222 is less than 90°. When the male rib 31, the female rib 32 and the connecting piece 2 are wound and connected, it is convenient for the second bending portion 222 to bend toward the direction close to the first bending portion 221, thereby reducing the difficulty of connecting the color steel tile 3 and the connecting piece 2.

[0094] The embodiment of the present application relates to a support 10 and a photovoltaic component. The support includes a base 1 and a connector 2. The base 1 includes a mounting plate 11 and a fixing plate 12. The fixing plate 12 is located on one side of the mounting plate 11 and is used to connect with the purlin. The connector 2 is installed on the mounting plate 11 and is used to connect with the color steel tile 3. A mounting groove 111 is provided on the side of the mounting plate 11 away from the fixing plate 12. A mounting beam 112 is provided in the mounting groove 111. The mounting beam 112 extends along the width direction X of the support 10, and the two ends of the mounting beam 112 are respectively connected to the two side walls of the mounting groove 111. The connector 2 includes a mounting hole 21. The connector 2 is sleeved on the mounting beam 112 through the mounting hole 21, which can reduce the possibility of the connector 2 being separated from the base 1, thereby improving the reliability of the connection between the color steel tile 3 and the purlin. When the color steel tile 3 is in a high-velocity wind field, the possibility of the color steel tile 3 being separated from the purlin can be reduced, thereby reducing the possibility of causing a safety accident.

[0095] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
