Description

Technical Field

[0001] The present application relates to the field of photovoltaic building technology, and in particular to color steel tile fixings and photovoltaic buildings. Background Art

[0002] With the development of photovoltaic power generation technology and the continuous reduction in its cost, more and more industrial and residential buildings are beginning to deploy photovoltaic power generation devices on roofs, walls, and exterior wall decorations. In construction projects, color-coated steel sheets are an effective carrier for fixing photovoltaic modules due to their light weight, high strength, and ease of structural fabrication according to design requirements.

[0003] Generally, color steel tiles are fixed and installed by brackets to fix the color steel tiles in the required position. However, the brackets used to install the traditional color steel tiles only play a supporting role. When the wind is strong, the color steel tiles may be blown off the brackets, and the wind resistance of the color steel tiles is poor. Summary of the Invention

[0016] In one embodiment, the plurality of first support arms and the plurality of second support arms are respectively formed by bending the connection portion in two opposite directions;

[0017] In the first direction, a width of an end of the second supporting arm contacting the connecting portion is smaller than a width of the connecting portion.

[0018] In one embodiment, in the first direction, the side of the connecting portion includes a middle section connected to the second support arm and an edge section located between the middle section and the first support arm, and a notch is formed in the edge section.

[0019] In one embodiment, the second support arm includes a support section and a limiting section, the support section is connected to the connecting portion, and the limiting section is provided at an end of the support section away from the connecting portion;

[0020] The limiting section includes a first limiting plate and a second limiting plate, the first limiting plate is intersected and connected with the supporting section, one end of the second limiting plate is connected to the first limiting plate, and the other end of the second limiting plate is suspended and faces the connecting part, and the supporting section, the first limiting plate and the second limiting plate form a limiting groove with an opening facing the connecting part, and the second limiting plate includes multiple layers of bent and stacked sub-plates.

[0036] See Figure 1 In some embodiments of the present application, a photovoltaic building 300 is provided, including color steel tiles 200 and multiple color steel tile fixings 100. The color steel tiles 200 are installed on multiple color steel tile fixings 100 to support and fix the color steel tiles 200 through the color steel tile fixings 100. The color steel tile fixings 100 have better fixing performance for the color steel tiles 200, which can prevent the color steel tiles 200 from being blown off when the wind is strong, thereby improving the wind resistance of the color steel tiles 200.

[0037] See Figure 1-Figure 2 The color steel tile fixing member 100 includes a base 10 and a second support arm 30. The second support arm 30 is provided on the base 10 and is used to support and fix the color steel tile 200. The base 10 includes a connecting portion 12 and a first support arm 14. The first support arm 14 is provided on one side of the connecting portion 12, and the second support arm 30 is provided on the other side of the connecting portion 12 facing away from the first support arm 14. The orthographic projection of the second support arm 30 toward the connecting portion 12 is at least partially misaligned with the orthographic projection of the first support arm 14 toward the connecting portion 12. The end of the second support arm 30 away from the connecting portion 12 is used to fix and install the color steel tile 200.

[0038] That is to say, the first support arm 14 supports the connecting part 12 to construct the base 10 into a stepped shape, and the positive projections of the first support arm 14 and the second support arm 30 toward the connecting part 12 are at least partially staggered, which is equivalent to the first support arm 14 and the second support arm 30 being staggered on both sides of the connecting part 12. In this way, when the second support arm 30 supports and fixes the color steel tile 200, the force transmitted by the color steel tile 200 to the second support arm 30 can be transmitted through the connecting part 12 and decomposed into the first support arm 14. Moreover, the first support arm 14 and the second support arm 30 are staggered, and the two are located in different directions. The color steel tile fixing part 100 as a whole can provide support in multiple different directions, and has better stability.

[0039] For example, when the external wind force becomes stronger, the airflow pressure on the color steel tile 200 is greater, and the external force transmitted to the second support arm 30 by the color steel tile 200 is also greater. However, at this time, the second support arm 30 can transmit part of the external force it receives to the staggered first support arm 14 through the connection part 12. In this way, the staggered first support arm 14 and the second support arm 30 decompose the external force applied by the color steel tile 200, and the second support arm 30 does not need to bear the external force alone. The color steel tile fixing part 100 as a whole can withstand greater external force, and the overall structure is more stable, thereby improving the wind resistance of the color steel tile 200 fixed on the color steel tile fixing part 100.

[0040] The first support arms 14 and the second support arms 30 each include a plurality of first support arms 14, which are spaced apart from each other on the same side of the connecting portion 12, and the second support arms 30, which are spaced apart from each other on the other side of the connecting portion 12 facing away from the first support arms 14. The orthographic projections of the first support arms 14 toward the connecting portion 12 and the orthographic projections of the second support arms 30 toward the connecting portion 12 are arranged in an interlaced manner, that is, the first support arms 14 and the second support arms 30 are arranged in an interlaced manner on both sides of the connecting portion 12. In this way, through the cooperation of the first support arms 14 and the second support arms 30, the force borne by the color steel tile fixing member 100 and transmitted by the color steel tile 200 can be decomposed into various directions of the first support arms 14 and the second support arms 30, thereby further dispersing the force received by the color steel tile fixing member 100, further improving the reliability of the color steel tile fixing member 100 in fixing the color steel tile 200 and the wind resistance performance of the color steel tile 200.

[0041] According to some embodiments of the present application, the connecting portion 12 has a first end 121 and a second end 123 that are opposite to each other along a first direction A, and a third end 125 and a fourth end 127 that are opposite to each other along a second direction B that intersects the first direction A. Some of the plurality of first support arms 14 are disposed at the first end 121, while another portion of the first support arms 14 is disposed at the second end 123. Some of the plurality of second support arms 30 are disposed at the third end 125, while another portion of the second support arms 30 is disposed at the fourth end 127. In this way, the plurality of first support arms 14 and the plurality of second support arms 30 are staggered at the first end 121, the second end 123, the third end 125, and the fourth end 127 in various directions of the connecting portion 12. In this way, the color steel tile fixing member 100 can be supported from multiple directions, dispersing the external forces applied to it, and improving its stability.

[0042] One or more first connecting arms can be provided at the first end 121 of the connecting part 12, and one or more first connecting arms can also be provided at the second end 123 of the connecting part 12. In this way, the first end 121 and the second end 123 of the connecting part 12 are respectively provided with at least one first connecting arm, and at least two first support arms 14 are provided on the same side of the connecting part 12 as a whole. In this way, supporting the connecting part 12 by at least two first support arms 14 is equivalent to supporting the entire color steel tile fixing part 100.

[0043] One or more second connecting arms can be provided at the third end 125 of the connecting part 12, and one or more second connecting arms can also be provided at the fourth end 127 of the connecting part 12, so that the third end 125 and the fourth end 127 of the connecting part 12 are respectively provided with at least one second connecting arm, and at least two second support arms 30 are provided on the side of the connecting part 12 as a whole facing away from the first connecting arm, so that the color steel tile 200 is more stably supported and fixed by at least two second support arms 30.

[0044] For example, the number of the first connecting arms and the number of the second connecting arms are both two, the two first connecting arms are arranged opposite to each other along the first direction A, and the two second connecting arms are arranged opposite to each other along the second direction B.

[0045] According to some embodiments of the present application, there is no contact between at least one second support arm 30 and the first support arm 14 adjacent thereto, so that there is no contact between the first support arm 14 and the second support arm 30, thereby preventing stress from concentrating at the position where the first support arm 14 and the second support arm 30 contact each other, so that the color steel tile fixing piece 100 is subjected to more uniform force.

[0046] See Figure 3In the first direction A, the distance between the two opposite ends of the first support arms 14 in contact with the connecting portion 12 is greater than the width of the end of the second support arm 30 in contact with the connecting portion 12, that is, the end of the second support arm 30 connected to the connecting portion 12 is narrower and will not contact the adjacent first support arm 14, preventing the second support arm 30 from being too wide and contacting the first support arm 14 at the connecting portion 12, thereby causing stress concentration.

[0047] In addition, the color steel tile fixing member 100 can be formed by bending, with the multiple first support arms 14 and the multiple second support arms 30 being formed by bending in opposite directions at the connecting portion 12. After bending, the first support arms 14 and the second support arms 30 are both located at the edge of the connecting portion 12. Furthermore, the bend between the first support arms 14 and the second support arms 30 forms an arc-shaped transition section. If the width of the second support arm 30 is exactly the width between the two first support arms 14, the arc-shaped transition section of the second support arm 30 is likely to contact the arc-shaped transition section of the first support arm 14, thereby easily generating stress concentration at the contact point.

[0048] In order to solve the above problem, in the first direction A, the width of the end of the second support arm 30 that contacts the connecting part 12 is smaller than the width of the connecting part 12, so that the end of the second support arm 30 connected to the connecting part 12 is narrower than the connecting part 12, and thus there can be a gap between the second support arm 30 and the first support arm 14 located at the edge of the connecting part 12, preventing the second support arm 30 from contacting the first support arm 14 at the corners of the connecting part 12 and causing stress concentration.

[0049] See Figure 4 Furthermore, in the first direction A, the side of the connecting portion 12 includes a middle section 128 connected to the second support arm 30 and an edge section 129 located between the middle section 128 and the first support arm 14. A notch 13 is provided in the edge section 129. As described above, in order to prevent stress concentration caused by contact between the first support arm 14 and the second support arm 30 at the bend transition, the width of the second support arm 30 in the first direction A is set to be relatively small, so that the outer periphery of the connecting portion 12 has a spare connecting section between the second support arm 30 and the first support arm 14. In the process of transmitting part of the external force applied to the second support portion to the first support arm 14 through the connecting portion 12, stress is easily concentrated in the connecting section due to its narrow width. Therefore, the notch 13 is provided in the connecting section to eliminate this narrow area and thus prevent stress concentration there. Moreover, the notch 13 on the connecting portion 12 is located at the edge of the connecting portion 12 and is parallel to the bending axis of the second support arm 30. The notch 13 can release the stress of the second support arm 30 and the connecting portion 12 during the production process, thereby improving the mechanical properties and usage stability of the color steel tile fixing piece 100.

[0050] Optionally, the side wall of the notch 13 on one side in the first direction A is flush with the side wall of the second support arm 30, and the side wall of the notch 13 on the other side in the first direction A is flush with the inner surface of the first support arm 14, so as to completely remove the material at the edge section 129 to effectively eliminate stress.

[0051] See Figure 1-Figure 2 According to some embodiments of the present application, each first support arm 14 includes a side panel 141 and a bottom panel 143 that are intersecting and connected. Each side panel 141 is intersecting and connected with the connecting portion 12. The bottom panel 143 in each first support arm 14 is arranged at an end of the side panel 141 away from the connecting portion 12. In this way, the side panel 141 is connected between the bottom panel 143 and the connecting portion 12. The base 10 is firmly supported by the bottom panel 143, and the connecting portion 12 is supported by the side panel 141, so that the base 10 is stepped.

[0052] In addition, in the process of designing the color steel tile fixing part 100, if it is necessary to adjust the overall height of the color steel tile fixing part 100, for example, the overall height of the color steel tile fixing part 100 needs to be set higher, in this case, the height of the first support arm 14 can be increased without adjusting the height of the second support arm 30. This can prevent the second support arm 30, which is already high, from being too high and resulting in insufficient support. In this way, the heights of the first support arm 14 and the second support arm 30 can be reasonably set according to needs, thereby improving the support stability of the color steel tile fixing part 100.

[0053] A hollow cavity 145 is formed between the multiple side panels 141 of the multiple first support arms 14 and the connecting portion 12. The bottom panel 143 of at least one first support arm 14 is located on the side of the side panel 141 facing away from the hollow cavity 145. That is, the bottom panel 143 extends outward, away from the hollow cavity 145. In this way, the bottom panel 143 is bent outward to more firmly support the color steel tile fixing member 100. In addition, the bottom panel 143 is used to be fixedly mounted to a base such as a roof purlin. The bottom panel 143 is bent outward, away from the hollow cavity 145, to facilitate the connection and fixing of the bottom panel 143 to the purlin.

[0054] For example, in the first direction A, the two bottom plates 143 of the two first support arms 14 arranged opposite to each other are extended in directions away from each other, so that the two bottom plates 143 of the two first support arms 14 are turned outward, and the base 10 and the color steel tile fixing parts 100 are supported by the two turned-out bottom plates 143, so the overall structure is more stable and it is convenient to install and fix the bottom plates 143 through fasteners.

[0055] According to some embodiments of the present application, the second support arm 30 includes a support section 32 and a limiting section 34. The support section 32 is connected to the connecting portion 12, and the limiting section 34 is provided at one end of the support section 32 away from the connecting portion 12. In this way, the second support arm 30 is constructed into a hook shape, and the hook-shaped second support arm 30 is buckled with the connecting portion 12 of the color steel tile 200 to achieve limited fixation of the color steel tile 200.

[0056] The limiting section 34 includes a first limiting plate 341 and a second limiting plate 343. The first limiting plate 341 is connected to the supporting section 32. One end of the second limiting plate 343 is connected to the first limiting plate 341. The other end of the second limiting plate 343 is suspended and faces the connecting part 12. The supporting section 32, the first limiting plate 341 and the second limiting plate 343 form a limiting groove 35 with an opening facing the connecting part 12. In this way, the color steel tile 200 can be limited and buckled through the limiting groove 35 with an opening facing the connecting part 12. The second support arm 30 can not only support the color steel tile 200, but also prevent the color steel tile 200 from detaching from the color steel tile fixing part 100 in a direction away from the base 10.

[0057] Furthermore, the second limiting plate 343 includes multiple layers of bent and stacked sub-plates 345. The second limiting plate 343 is formed by bending and stacking the sub-plates 345 multiple times, so that the thickness of the second limiting plate 343 is thicker and the strength of the second limiting plate 343 is greater. When the color steel tile 200 has a tendency to move away from the base 10 in the vertical direction under the action of wind, the second limiting plate 343 is subjected to the vertical upward force of the color steel tile 200. At this time, the second limiting plate 343 has multiple layers of sub-plates 345 stacked by bending, and its own strength is strong. It will not be easily deformed and maintains the limitation of the color steel tile 200, thereby improving the wind-proof performance of the color steel tile 200.

[0058] According to some embodiments of the present application, a reinforcing rib 50 is provided on the color steel tile fixing member 100. The reinforcing rib 50 extends from the second support arm 30 along the longitudinal direction of the second support arm 30 to the connecting portion 12. In this way, the reinforcing rib 50 extends along the longitudinal direction of the second support arm 30, thereby increasing the strength of the second support arm 30 in the longitudinal direction and preventing the second support arm 30 from deforming in its own longitudinal direction. In addition, the reinforcing rib 50 extends from the second support arm 30 to the connecting portion 12, which is equivalent to the reinforcing rib 50 passing through the connection point where the second support arm 30 and the connecting portion 12 are connected to each other, thereby strengthening the mechanical connection between the second support arm 30 and the connecting portion 12, allowing the force on the second support arm 30 to be directly transmitted to the connecting portion 12, and at the same time allowing the base 10 to better support the second support arm 30 to withstand a larger load and improve stability.

[0059] Specifically, the reinforcing rib 50 is formed by the second support arm 30 and the connecting portion 12 being convex inwardly, for example, by stamping.

[0060] According to some embodiments of the present application, the color steel tile fixing member 100 has elastic deformation capability, for example, it is made of spring steel. The color steel tile fixing member 100 can undergo elastic deformation when subjected to an external load, and can return to its original shape when the external load disappears, thereby reducing the impact of external impact on the color steel tile fixing member 100 and the photovoltaic building 300.

[0061] Generally, the weather outdoors will change in many ways. When there is wind outdoors, the color steel tile 200 will impose an external load on the color steel tile fixing part 100 under the action of wind. When the wind stops, the color steel tile 200 is no longer affected by the wind, and the external load on the color steel tile fixing part 100 formed by the wind disappears. The color steel tile fixing part 100 has elastic deformation ability and can adaptively deform elastically when there is wind. When the wind stops, the color steel tile fixing part 100 can restore the deformation and return to its original state. The color steel tile fixing part 100 will not be deformed due to the intermittent influence of external wind force, thereby improving the structural stability of the color steel tile fixing part 100.

[0062] Specifically, when the wind is strong outdoors, the support section 32 and the limiting section 34 of the second support arm 30 directly receive the external load transmitted by the color steel tile 200, and the support section 32 and the limiting section 34 can adaptively undergo elastic deformation. When the wind stops outdoors, the support section 32 and the limiting section 34 can restore the deformation and continue to restore the original state to limit the installation of the color steel tile 200. In this way, the external intermittent load will not cause the color steel tile fixing part 100 to deform, thereby improving the structural stability of the color steel tile fixing part 100.

[0063] According to some embodiments of the present application, the present application further provides a color steel tile fixing member 100 as described in any of the above embodiments. The color steel tile fixing member 100 includes a base 10 and a second support arm 30. The second support arm 30 is provided on the base 10 and is used to support and fix the color steel tile 200. The base 10 includes a connecting portion 12 and a first support arm 14. The first support arm 14 is provided on one side of the connecting portion 12. The second support arm 30 is provided on the other side of the connecting portion 12 facing away from the first support arm 14. The orthographic projection of the second support arm 30 toward the connecting portion 12 is at least partially misaligned with the orthographic projection of the first support arm 14 toward the connecting portion 12. The end of the second support arm 30 away from the connecting portion 12 is used to fix and install the color steel tile 200.

[0064] That is to say, the first support arm 14 supports the connecting part 12 to construct the base 10 into a stepped shape, and the positive projections of the first support arm 14 and the second support arm 30 toward the connecting part 12 are at least partially staggered, which is equivalent to the first support arm 14 and the second support arm 30 being staggered on both sides of the connecting part 12. In this way, when the second support arm 30 supports and fixes the color steel tile 200, the force transmitted by the color steel tile 200 to the second support arm 30 can be transmitted through the connecting part 12 and decomposed into the first support arm 14. Moreover, the first support arm 14 and the second support arm 30 are staggered, and the two are located in different directions. The color steel tile fixing part 100 as a whole can provide support in multiple different directions, with better stability, thereby improving the wind resistance of the color steel tile 200.

[0065] For example, when the external wind force becomes stronger, the airflow pressure on the color steel tile 200 is greater, and the external force transmitted to the second support arm 30 by the color steel tile 200 is also greater. However, at this time, the second support arm 30 can transmit part of the external force it receives to the staggered first support arm 14 through the connection part 12. In this way, the staggered first support arm 14 and the second support arm 30 decompose the external force applied by the color steel tile 200, and the second support arm 30 does not need to bear the external force alone. The color steel tile fixing part 100 as a whole can withstand greater external force, and the overall structure is more stable, thereby improving the wind resistance of the color steel tile 200 fixed on the color steel tile fixing part 100.

[0066] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
