Description

Technical Field

[0001] The present application relates to the technical field of steel structure installation, and in particular to a steel structure and a photovoltaic system. Background Art

[0002] The connection between the superstructure and foundation of a steel structure building is the design focus of the steel structure. The reliability and durability of the connection between the steel pipe pile foundation and the column are the key considerations. However, in the existing connection method, the central axis of the steel pipe pile foundation and the column is not aligned, resulting in a decrease in connection reliability due to connection deviation and incomplete welding. Utility Model Content

[0003] In view of this, the present application provides a steel structure and a photovoltaic system that achieves alignment of the central axes of a column and a foundation.

[0004] The embodiment of the present application provides a steel structure, including a column and a foundation, and also including a first connecting member and a second connecting member. The first connecting member is fixed to one of the column and the foundation, and the first connecting member has a guide portion, and the guide portion has a root and an end portion, and the root portion is fixed to one of the column and the foundation, and the radial size of the guide portion decreases from the root portion to the end portion. The second connecting member is fixed to the other of the column and the foundation, and the second connecting member is provided with a guide hole, and the guide portion is used to be inserted into the guide hole.

[0005] In the above-mentioned steel structure, when the column is docked with the foundation, due to the gravity of the column and the upper structure of the building, the guide part whose radial dimension decreases from the root to the end can slide relative to the hole wall of the guide hole until the guide part is inserted into the guide hole, thereby realizing rapid alignment of the first connecting member and the second connecting member, that is, driving the column and the foundation to dock quickly, facilitating the connection operation of the column and the foundation.

[0006] In some embodiments, the guide hole and the guide portion are coaxial, so that when the guide portion is inserted into the guide hole, the central axes of the base and the column can coincide, thereby avoiding the problem of misalignment between the base and the column.

[0007] In some embodiments, the guide portion includes a plurality of guide plates, and the width of each guide plate along the radial direction of the column or base decreases from the root to the end, and / or the plurality of guide plates are distributed around the column or base in a circumferential direction. In this way, the guide portion generally forms a conical structure, which facilitates the insertion of the guide portion into the guide hole.

[0008] In some embodiments, the guide plate is a triangular plate or a trapezoidal plate.

[0009] In some embodiments, the outer side surface of the guide portion includes a guide surface and a transition surface. The guide surface is inclined from the outside to the inside in the direction from the root to the end. Along the radial direction of the column or the foundation, the distance between the transition surface and the axis of the column or the foundation is less than or equal to the radius of the guide hole. During the process of inserting the guide portion into the guide hole, the inclined guide surface can slide relative to the hole wall of the guide hole to correct the problem of misalignment between the foundation and the column. After the guide portion is inserted into the guide hole, the transition surface can be accommodated in the guide hole and cooperate with the hole wall of the guide hole to improve the alignment stability of the first connector and the second connector.

[0010] In some embodiments, the first connecting member also includes a first fixing plate, and the second connecting member includes a second fixing plate. The first fixing plate is arranged on the periphery of the guide portion, and a portion of the guide hole is arranged on the second fixing plate. The first fixing plate is fixedly connected to the second fixing plate, so that after the guide portion is inserted into the guide hole, the relative positions of the first connecting member and the second connecting member can be fixed by the first fixing plate and the second fixing plate, thereby further improving the alignment stability of the first connecting member and the second connecting member and facilitating subsequent installation operations.

[0011] In some embodiments, the first fixing plate and the second fixing plate are both provided with fixing holes, and the fixing hole of at least one of the first fixing plate and the second fixing plate is a waist-shaped hole. In this way, when the foundation and / or the column undergoes slight deformation, or when the fixing holes on the first fixing plate and the second fixing plate are not completely aligned, the fixing holes on the first fixing plate and the second fixing plate can still be connected to allow fasteners to pass through, which is conducive to reducing assembly difficulty and precision and improving assembly efficiency.

[0012] In some embodiments, the first connecting member also includes a first connecting plate, and the second connecting member also includes a second connecting plate, the first connecting plate connects the guide portion and one of the column and the foundation, the first fixing plate connects the first connecting plate, and the second connecting plate connects the second fixing plate and the other of the column and the foundation.

[0013] In some embodiments, there are multiple first connecting plates, which are distributed around the circumferential direction of the column or the base; there are multiple second connecting plates, which are distributed around the circumferential direction of the column or the base, and another part of the guide hole is formed between the multiple second connecting plates.

[0014] In this way, the assembly structures of the guide part and the positioning hole on the column and the foundation are simple and low in cost, which facilitates the connection operation between the column and the foundation.

[0015] In some embodiments, the first fixing plate is configured to be located outside one of the column and the foundation to facilitate the connection operation of the first connecting member and the second connecting member.

[0016] In some embodiments, the second fixing plate is configured to be located outside the other of the column and the foundation to facilitate the connection operation of the first connector and the second connector.

[0017] In some embodiments, the steel structure further includes a packaging component, which is configured to surround the outer periphery of at least one of the first connector and the second connector, and is welded between the column and the foundation. Due to factors such as the complex outdoor installation environment and the large size of the steel structure, the size of the column and the foundation varies slightly. After the column and the foundation are aligned and corrected by the first connector and the second connector, the size of the packaging component is measured on-site to improve the dimensional accuracy, so as to facilitate the welding of the packaging component between the aligned column and the foundation. The tube walls of the packaging component, the column, and the foundation are continuous, forming a continuous supporting main structure, which is conducive to improving the supporting strength.

[0018] An embodiment of the present application further provides a photovoltaic system, comprising the steel structure described in the above embodiment and a photovoltaic component supported by the steel structure.

[0019] In the steel structure of the present application, when the central axis of the column is deflected relative to the central axis of the foundation, due to the gravity of the column and the upper structure of the building, the outer side surface of the guide part with a reduced radial dimension can slide relative to the hole wall of the guide hole. In this process, the column or the foundation may be slightly deformed until the guide part is inserted into the guide hole to achieve alignment with the first connecting member and the second connecting member, that is, to drive the column and the foundation to connect quickly, so that the relative position of the column and the foundation remains stable, so as to facilitate the connection operation of the column and the foundation.

[0057] In order to further illustrate the technical means and effects adopted by the present application to achieve the intended application purpose, the following is combined with the drawings and implementation methods. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0059] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0060] Please also see Figure 1 and Figure 2 , Figure 1 A steel structure 200 in one embodiment is illustrated. Figure 2 A steel structure 200 in an embodiment is illustrated. An embodiment of the present application provides a steel structure 200. The steel structure 200 is applied to the field of construction, and the steel structure 200 includes a plurality of foundations 2003 and a plurality of columns 2001. The plurality of foundations 2003 are generally installed on land or at sea, etc., as a land and sea support foundation. The plurality of columns 2001 are generally first connected to a building superstructure 400, such as a roof, a platform, etc. The plurality of columns 2001 need to be connected one-to-one with the plurality of foundations 2003, so as to complete the installation of the building superstructure 400 on land or at sea.

[0061] The ends of the column 2001 and the foundation 2003 opposite to each other are generally tubular sections formed by an annular wall, and the tubular sections are, for example, tubular structures of round tubes or square tubes. The column 2001 connected to the building superstructure 400 and the foundation 2003 connected to land or sea are similar to cantilever structures, and there are problems of thermal expansion and contraction when the temperature changes; due to the large size, they are usually installed outdoors, and they may be slightly deformed by factors such as wind or external operating force; the relative position accuracy of multiple columns 2001 installed on the building superstructure 400 is different due to factors such as human and environmental factors; the above problems may cause the distance between two columns 2001 to be actually not equal to the distance between the two correspondingly connected foundations 2003.

[0062] In one connection mode, such as Fig. 9 As shown, the column 2001 and the foundation 2003 use a flat plate as an intermediate transition structure 500, that is, the column 2001 is welded to one side of the flat plate, and the foundation 2003 is welded to the other side of the flat plate, but the two opposite sides of the flat plate are both flat, and the flat plate has no positioning effect on the foundation 2003 and the column 2001, resulting in a serious misalignment between the column 2001 and the foundation 2003, which is inconsistent with the theoretical relative position after the connection, and the central axes of the tubular sections of the column 2001 and the foundation 2003 are seriously misaligned, affecting the overall safety and reliability of the steel structure 200.

[0063] When a single column 2001 is installed with a single foundation 2003, deformation caused by factors such as temperature and force may also cause misalignment between the column 2001 and the foundation 2003 connected by the plate and the guide structure.

[0064] The steel structure 200 provided in the present application can align the tubular section of the column 2001 and the tubular section of the foundation 2003 when the column 2001 is docked with the foundation 2003, so as to improve the coaxiality of the central axis of the tubular section of the column 2001 and the central axis of the tubular section of the foundation 2003, so as to improve the alignment accuracy of the column 2001 and the foundation 2003, thereby improving the overall safety and reliability of the steel structure 200.

[0065] The following embodiment takes the cylindrical tube sections of the column 2001 and the foundation 2003 as a circular tubular structure as an example to describe the steel structure 200 in detail. It can be understood that other shapes of tubular sections can also be used to guide the column 2001 and the foundation 2003 through the steel structure 200 to improve the alignment accuracy of the column 2001 and the foundation 2003.

[0066] See also Figure 2 and Figure 3 , Figure 2 A steel structure 200 is schematically shown. Figure 3The column 2001 of the steel structure 200 is schematically connected to the foundation 2003. The steel structure 200 includes a first connection member 10 and a second connection member 20. The first connection member 10 is configured to be fixed to the inner wall of the column 2001, and the second connection member 20 is configured to be fixed to the inner wall of the foundation 2003. In one embodiment, the first connection member 10 is welded to the inner wall of the column 2001, and the second connection member 20 is welded to the inner wall of the foundation 2003, but it is not limited thereto. In other embodiments, the first connection member 10 can also be fixed to the foundation 2003, and the second connection member 20 can also be fixed to the column 2001.

[0067] See also Figure 3 , Figure 4 and Figure 5 The first connecting member 10 has a guide portion 12, and the guide portion 12 has a root and an end. When the first connecting member 10 is fixed to the column 2001, the root of the guide portion 12 is directly or indirectly fixed to the column 2001. When the first connecting member 10 is fixed to the foundation 2003, the root of the guide portion 12 is directly or indirectly fixed to the foundation 2003. From the root to the end, the radial dimension of the guide portion 12 is reduced, so that the guide portion 12 is roughly similar to a cone or a frustum. The second connecting member 20 is provided with a guide hole 2013, and the guide portion 12 is used to be inserted into the guide hole 2013.

[0068] The central axis of the column 2001 is the central axis of the tubular section connected to the first connector 10 in the column 2001. The central axis of the foundation 2003 is the central axis of the tubular section connected to the second connector 20 in the foundation 2003. In the process of hoisting the building superstructure 400 and driving the column 2001 to move relative to the foundation 2003 and move downward for assembly, when the central axis of the column 2001 deflects relative to the central axis of the foundation 2003, due to the gravity of the column 2001 and the building superstructure 400, the inclined outer side surface of the guide part 12 slides relative to the hole wall of the guide hole 2013. In this process, the column 2001 or the foundation 2003 may be slightly deformed until the guide part 12 is inserted into the guide hole 2013, so as to realize the alignment of the first connector 10 and the second connector 20, that is, to drive the central axes of the column 2001 and the foundation 2003 to align so as to facilitate the connection operation of the column 2001 and the foundation 2003.

[0069] In some embodiments, the guide hole 2013 and the guide portion 12 are coaxial. Further, the base 2003 and the guide hole 2013 can be coaxial, and the guide portion 12 and the column 2001 can be coaxial, so that when the guide portion 12 is inserted into the guide hole 2013, the central axes of the base 2003 and the column 2001 can coincide, thereby improving the alignment accuracy of the column 2001 and the base 2003 and avoiding the problem of misalignment between the base 2003 and the column 2001.

[0070] See also Figure 4 , Figure 5 and Figure 6 In some embodiments, the guide portion 12 includes a plurality of guide plates 121, and the width of each guide plate 121 along the radial direction of the column 2001 or the base 2003 decreases from the root to the end. The plurality of guide plates 121 can also be distributed around the circumferential direction of the column 2001 or the base 2003. In the embodiment of the present application, the plurality of guide plates 121 are generally distributed in a cross shape or a cross shape, but the present application is not limited thereto. In this way, the guide portion 12 is generally wide at the top and narrow at the bottom, which is convenient for inserting into the guide hole 2013.

[0071] In one embodiment, the guide plate 121 is a triangular plate or a trapezoidal plate, but the present application is not limited thereto.

[0072] In some embodiments, the outer side surface of the guide portion 12 includes a guide surface 113 and a transition surface 115. The guide surface 113 is close to the end of the guide portion 12, the transition surface 115 is close to the root of the guide portion 12, and the guide surface 113 intersects with the transition surface 115. The guide surface 113 and the transition surface 115 can be specifically arranged on the outer side surface of the guide plate 121. From the root to the end, the guide surface 113 is inclined from the outside to the inside. Along the radial direction of the column 2001 or the base 2003, the distance between the transition surface 115 and the axis of the column 2001 or the base 2003 is less than or equal to the radius of the guide hole 2013. In the embodiment of the present application, the transition surface 115 can be arranged roughly parallel to the axis of the column 2001 or the base 2003. During the process of inserting the guide portion 12 into the guide hole 2013, if the column 2001 and the base 2003 are offset, the inclined guide surface 113 can slide relative to the hole wall of the guide hole 2013 to correct the offset problem between the base 2003 and the column 2001. After the guide portion 12 is inserted into the guide hole 2013, the transition surface 115 can be received in the guide hole 2013 and cooperate with the hole wall of the guide hole 2013 to improve the alignment stability of the first connecting member 10 and the second connecting member 20.

[0073] In some embodiments, the first connector 10 further includes a first fixing plate 13, and the second connector 20 includes a second fixing plate 23. The first fixing plate 13 is disposed on the periphery of the guide portion 12, and a portion of the guide hole 2013 is disposed on the second fixing plate 23. The first fixing plate 13 is fixedly connected to the second fixing plate 23, so that after the guide portion 12 is inserted into the guide hole 2013, the relative positions of the first connector 10 and the second connector 20 can be fixed by the first fixing plate 13 and the second fixing plate 23, further improving the alignment stability of the first connector 10 and the second connector 20, and facilitating subsequent installation operations. The fixing method between the first fixing plate 13 and the second fixing plate 23 includes, but is not limited to, welding, mechanical locking, etc.

[0074] Specifically, the first fixing plate 13 and the second fixing plate 23 are substantially annular plates, but are not limited thereto. Along the axial direction of the column 2001 or the base 2003, a first abutting surface 101 is formed on one side of the first fixing plate 13, and a second abutting surface 201 is formed on one side of the second fixing plate 23, and the first abutting surface 101 and the second abutting surface 201 are arranged opposite to each other. After the guide portion 12 is inserted into the guide hole 2013, the first abutting surface 101 fits with the second abutting surface 201, and the second abutting surface 201 prevents the first abutting surface 101 from deflecting, that is, prevents the guide portion 12 from sliding relative to the guide hole 2013, so that the relative position of the column 2001 and the base 2003 remains stable.

[0075] It can be understood that the first abutting surface 101 and the second abutting surface 201 are planes, which can be understood to include smooth planes and rough planes, such as planes with anti-slip patterns, planes with bumps caused by increased friction or process flow.

[0076] See also Figure 5 and Figure 8 In some embodiments, the first fixing plate 13 and the second fixing plate 23 are connected and fixed by fasteners 300. The first fixing plate 13 and the second fixing plate 23 are both provided with fixing holes, and the fasteners 300 can be set through the fixing holes of the two to mechanically lock the first fixing plate 13 and the second fixing plate 23. The fixing hole of at least one of the first fixing plate 13 and the second fixing plate 23 is a waist-shaped hole. In this way, when the base 2003 and / or the column 2001 are slightly deformed, or the fixing holes on the first fixing plate 13 and the second fixing plate 23 are not completely aligned, the fixing holes on the first fixing plate 13 and the second fixing plate 23 can still be connected for the fasteners 300 to pass through, which is conducive to reducing the difficulty and accuracy of assembly and improving assembly efficiency.

[0077] In one embodiment, the fixing hole on the first fixing plate 13 is set as the first fixing hole 1011, and the first fixing hole 1011 passes through the first abutting surface 101. The fixing hole on the second fixing plate 23 is set as the second fixing hole 2011, and the second fixing hole 2011 passes through the second abutting surface 201. The second fixing hole 2011 extends in the circumferential direction so that the first fixing hole 1011 and the second fixing hole 2011 are kept in communication within a set distance of relative movement in the circumferential direction, and the first connecting member 10 and the second connecting member 20 are connected and fixed by the fastener 300 in cooperation with the first fixing hole 1011 and the second fixing hole 2011. Because the second fixing hole 2011 and the first fixing hole 1011 are kept in communication within a set distance in the circumferential direction, when the base 2003 and / or the column 2001 are slightly deformed, the first fixing hole 1011 and the second fixing hole 2011 can still be connected to allow the fastener 300 to pass through.

[0078] The fastener 300 fixes the first connecting member 10 and the second connecting member 20 to be connected, thereby making the relative position of the foundation 2003 and the column 2001 stable and able to resist external forces such as external wind force and welding force, which is beneficial to improving the relative stability of the foundation 2003 and the column 2001 under external forces, and further helps to ensure that the central axes of the column 2001 and the foundation 2003 are aligned.

[0079] Please refer again Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 In some embodiments, the first connecting member 10 further includes a first connecting plate 11, and the second connecting member 20 further includes a second connecting plate 21. The first connecting plate 11 connects the guide portion 12 and the column 2001, and the first fixing plate 13 connects the first connecting plate 11, so that the first fixing plate 13 and the guide portion 12 are relatively fixed to the column 2001 through the first connecting plate 11. The second connecting plate 21 connects the second fixing plate 23 and the base 2003.

[0080] The number of the first connecting plates 11 is multiple, and the multiple first connecting plates 11 are distributed around the circumferential direction of the column 2001 or the base 2003. Specifically, the multiple first connecting plates 11 are arranged along the circumferential direction and are respectively welded to the inner wall of the column 2001, that is, the multiple first connecting plates 11 are arranged around the central axis of the column 2001. The first fixing plate 13 is connected to each first connecting plate 11. Each first connecting plate 11 can be connected to a guide plate 121 as a whole. A connecting surface 111 is formed on the side of the first connecting plate 11 facing the guide plate 121. The connecting surfaces 111 of the multiple first connecting plates 11 are arranged in the same plane. The multiple connecting surfaces 111 are in contact with and fixedly connected to the side of the first fixing plate 13 away from the first abutting surface 101. In one embodiment, the connecting surface 111 is perpendicular to the central axis of the column 2001, but is not limited thereto. At this time, the connecting surface 111 is parallel to the first abutting surface 101 of the first fixing plate 13, so that the first fixing plate 13 is made of a plate-like structure to reduce costs. It is understood that in other embodiments, the connecting surfaces 111 and the first abutting surface 101 on opposite sides of the first fixing plate 13 may also be non-parallel. For example, in another embodiment, the first abutting surface 101 and the side of the first fixing plate 13 facing away from the first abutting surface 101 are respectively adapted uneven wall surfaces to increase the welding length of the first abutting surface 101 and the first fixing plate 13.

[0081] A through hole 1301 is also provided in the middle region of the first fixing plate 13. A plurality of first fixing holes 1011 are arranged around the circumference of the through hole 1301. A plurality of guide plates 121 pass through the through hole 1301, that is, the guide portion 12 passes through the through hole 1301, so that the guide surfaces 113 of the plurality of guide plates 121 are located on the side of the first abutting surface 101 facing the base 2003.

[0082] The guide surfaces 113 of the plurality of guide plates 121 are inclined at the same angle relative to the first abutting surface 101 and are arranged circumferentially, that is, arranged around the central axis of the column 2001 to form the guide surfaces 103 of the intermittent guide portions 12 .

[0083] The two opposite sides of the transition surface 115 on the outer side of the guide plate 121 are respectively connected to the connection surface 111 and the guide surface 113. The transition surface 115 is in contact with the hole wall of the through hole 1301 of the first fixing plate 13. The transition surfaces 115 of the first connecting plates 11 provide inner support for the first fixing plate 13, which is beneficial to improve the overall strength of the first fixing plate 13.

[0084] In one embodiment, it can be understood that in other embodiments, there may also be a gap between the transition surface 115 and the hole wall of the through hole 1301 .

[0085] In one embodiment, the portion where the transition surface 115 is connected to the guide surface 113 passes through the through hole 1301 and is located on the side of the first abutting surface 101 away from the connecting surface 111. The transition surfaces 115 of the plurality of first connecting plates 11 are arranged circumferentially and are used to contact the hole wall of the guide hole 2013. The transition surface 115 is in contact with the guide surface 113, and the guide surface 113 slides relative to the hole wall of the guide hole 2013, which can drive the transition surface 115 to enter the guide hole 2013. When the distance between the transition surface 115 and the central axis of the column 2001 is equal to the radius of the guide hole 2013, the transition surfaces 115 of the plurality of first connecting plates 11 arranged circumferentially contact the hole wall of the guide hole 2013 of the second connecting member 20, further improving the alignment stability of the first connecting member 10 and the second connecting member 20.

[0086] It is understandable that in other implementations, when the distance between the adapter surface 115 and the central axis of the column 2001 is smaller than the radius of the guide hole 2013 , there may be a gap between the adapter surface 115 and the guide hole 2013 to facilitate the insertion of the guide portion 12 into the guide hole 2013 .

[0087] In one embodiment, the plurality of first connecting plates 11 extend toward the central axis of the through hole 1301 until the plurality of first connecting plates 11 converge, but the invention is not limited thereto. The plurality of first connecting plates 11 may be abutted or welded, so that the plurality of first connecting plates 11 support each other inside the column 2001, which is beneficial to improving the strength of the steel pipe section of the column 2001.

[0088] The first connecting member 10 is connected by a plurality of guide plates 121 and the first fixing plate 13 to form a guide surface 103 and a first abutting surface 101 arranged along the circumferential direction, and has a simple structure, is easy to assemble and has a low cost.

[0089] In one embodiment, the first connecting member 10 further includes a plurality of reinforcing plates 15. The plurality of reinforcing plates 15 are arranged along the circumferential direction. At least one reinforcing plate 15 is arranged between every two first connecting plates 11. The reinforcing plates 15 are used to be connected between the first fixing plate 13 and the inner wall of the column 2001 to improve the relative position stability between the first fixing plate 13 and the column 2001. It can be understood that in other embodiments, the reinforcing plates 15 can also be omitted.

[0090] It is understood that the guide surface 103 of the guide portion 12 may also be a continuous surface, for example, Figure 7 As shown, in another embodiment, the first connecting member 10a includes a welded first fixing plate 13a and a guide member 17. The first fixing plate 13a is connected to the tubular section of the column 2001, and the guide member 17 is roughly a spherical top structure. The spherical top surface of the guide member 17 is a continuous guide surface 103a. The first fixing plate 13a is located on the outer periphery of the guide member 17 to form a first abutment surface 101a. The guide surface 103a is inclined relative to the first abutment surface 101a, and the inclination angle is variable, but the guide surface 103a can also move relative to the hole wall of the guide hole 2013, thereby guiding the central axis of the column 2001 to align with the central axis of the base 2003.

[0091] The number of the second connecting plates 21 is also multiple, and the multiple second connecting plates 21 are configured to be connected to the foundation 2003. The second fixing plate 23 is connected to the same side of the multiple second connecting plates 21. The multiple second connecting plates 21 are distributed around the column 2001 or the foundation 2003 in the circumferential direction to improve the force uniformity of the second fixing plates 23 and the foundation 2003. Another part of the guide hole 2013 is formed between the multiple second connecting plates 21.

[0092] In one embodiment, the second fixing plate 23 is substantially annular. The second connecting plate 21 is connected to the outer peripheral edge of the second fixing plate 23 along the radial direction of the second fixing plate 23, thereby improving the connection strength between the second connecting plate 21 and the second fixing plate 23.

[0093] The welding and assembly of the plurality of second connecting plates 21 and the second fixing plate 23 is simple and low in cost.

[0094] In one embodiment, a second fixing hole 2011 is arranged between two circumferentially adjacent second connecting plates 21, and a first fixing hole 1011 is arranged between the circumferentially adjacent reinforcing plate 15 and first connecting plate 11. When the reinforcing plate 15 does not exist, a first fixing hole 1011 is arranged between two adjacent first connecting plates 11. The outer side surfaces of the first connecting plate 11, the second connecting plate 21 and the reinforcing plate 15 are all inclined from outside to inside, so as to provide installation space for the fastener 300 and reduce the difficulty of installing the fastener 300. The first connecting plate 11, the second connecting plate 21 and the reinforcing plate 15 act as reinforcing ribs, providing connection support for the first fixing plate 13 and the second fixing plate 23, and improving the connection strength.

[0095] It can be understood that in other embodiments, a plurality of connection holes (first fixing hole 1011 and second fixing hole 2011 ) may be arranged between two adjacent plates (first connection plate 11 , reinforcing plate 15 , and second connection plate 21 ).

[0096] It is understandable that in other embodiments, the first fixing plate 13 and the second fixing plate 23 may be welded to achieve the connection and fixation of the first connecting member 10 and the second connecting member 20 .

[0097] In one embodiment, multiple guide plates 121 protrude to the outside of the column 2001, so that the second fixing plate 23 is located outside the column 2001; multiple second connecting plates 21 protrude to the outside of the base 2003, so that the second abutment where the plate is connected to the second connecting plate 21 is located outside the base 2003, but it is not limited to this.

[0098] The first fixing plate 13 is located outside the column 2001 , and the second fixing plate 23 is located outside the foundation 2003 , which helps to connect the first fixing plate 13 and the second fixing plate 23 , and further helps to connect the first connecting member 10 and the second connecting member 20 .

[0099] It can be understood that in other embodiments, one of the first fixing plate 13 and the second fixing plate 23 is located in the external space between the column 2001 and the foundation 2003 .

[0100] Please refer again Figure 2 and Figure 3 In some embodiments, the steel structure 200 further includes a packaging member 30. The packaging member 30 is configured to surround the outer periphery of at least one of the first connecting member 10 and the second connecting member 20, and is welded between the column 2001 and the foundation 2003.

[0101] The size of the package 30 is confirmed after the first abutting surface 101 and the second abutting surface 201 are attached. Due to factors such as outdoor installation and the large size of the steel structure 200, the size of the column 2001 and the foundation 2003 is slightly changed. After the column 2001 and the foundation 2003 are aligned and guided by the first connecting member 10 and the second connecting member 20, the size of the package 30 is measured on site to improve the size accuracy, so that the package 30 can be welded between the aligned column 2001 and the foundation 2003.

[0102] The packaging member 30 is welded between the column 2001 and the foundation 2003 to form a tubular structure. One end of the tube wall of the packaging member 30 is connected to the tube wall of the column 2001, and the other end of the tube wall of the packaging member 30 is connected to the tube wall of the foundation 2003. The tube walls of the column 2001, the packaging member 30 and the foundation 2003 are continuous, forming a continuous supporting main structure, which effectively improves the supporting strength.

[0103] To facilitate welding of the package 30 , the package 30 may be divided into several parts and welded sequentially. For example, the package 30 is divided into two arc plates, and the two arc plates are welded sequentially between the column 2001 and the base 2003 .

[0104] In one embodiment, the packaging member 30 is located outside the first fixing plate 13 and the second fixing plate 23 to seal the column 2001 and the base 2003 so that the column 2001 and the base 2003 form an integrated visual effect.

[0105] It can be understood that in other embodiments, the first abutment surface 101 and the central axis of the column 2001 can be arranged at an angle, but as long as the guide surface 103 is arranged around the central axis of the column 2001, the guide surface 103 slides relative to the hole wall of the guide hole 2013 under the drive of gravity until the first abutment surface 101 fits the second abutment surface 201, the second abutment surface 201 stops the movement of the first abutment surface 101, and the guide surface 103 stops sliding, thereby achieving the correction of the first connecting member 10 and the second connecting member 20.

[0106] An embodiment of the present application further provides a photovoltaic system, comprising the steel structure 200 described in the above embodiment and a photovoltaic component supported by the steel structure 200 .

[0107] In the steel structure 200 of the present application, when the central axis of the column 2001 deflects relative to the central axis of the foundation 2003, due to the gravity of the column 2001 and the building superstructure 400, the guide surface 103 of the guide part 12 slides relative to the hole wall of the guide hole 2013. In this process, the column 2001 or the foundation 2003 may be slightly deformed until the first abutting surface 101 and the second abutting surface 201 are in contact, and the guide part 12 stops sliding relative to the guide hole 2013, so as to achieve the alignment of the first connecting member 10 and the second connecting member 20, that is, to drive the central axis of the column 2001 and the foundation 2003 to align. The two planes (the first abutting surface 101 and the second abutting surface 201) are in contact, so that the relative position of the column 2001 and the foundation 2003 remains stable, so that the column 2001 and the foundation 2003 can be connected.

[0108] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not intended to be limiting of the present application. As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
