Description

Technical Field

[0001] The embodiments of this application relate to the technical field of building construction, and more particularly to a steel frame support structure. Background Technology

[0002] A steel frame bracing structure typically includes steel columns, steel beams, and steel braces. The steel columns extend vertically and connect to the foundation. The steel beams extend perpendicularly to the steel columns and are connected to them. The steel braces extend at an angle relative to both the steel columns and beams.

[0003] For a steel brace located vertically between the foundation and the steel beam, the upper end of the steel brace can be connected to a steel column and a steel beam, and the lower end of the steel brace can be connected to another steel column.

[0004] The steel frame support structure connected in the above manner has poor stability, which affects the reliability of the steel frame support structure. Utility Model Content

[0005] Embodiments of this application provide a steel frame support structure for improving the stability and reliability of steel frame support structures.

[0006] On one hand, embodiments of this application provide a steel frame support structure. The steel frame support structure includes steel columns, a first steel beam, and a first steel brace. There are multiple steel columns, including adjacent first and second steel columns. Each steel column includes a column body and a column base, with the column base connected to one end of the column body and connected to a foundation. The first steel beam is adjacent to and spaced apart from the foundation, connecting the first and second steel columns. The upper end of the first steel brace is connected to the first steel column and the first steel beam, and the lower end of the first steel brace is connected to the second steel column. The lower end of the first steel brace is also connected to at least one of the foundation and a ground beam. The ground beam and the foundation are adjacent in the XY plane, which is perpendicular to the extension direction of the steel columns.

[0007] In some possible implementations, the first steel brace includes a steel brace body and a first base plate, the first base plate being connected to one end of the steel brace body and having a first through hole. The steel frame support structure also includes a first anchor plate, a first anchor bolt, and a first nut. The first anchor plate is embedded in at least one of the foundation and the ground beam. The first anchor bolt passes through the first through hole and is connected to the first anchor plate, with a portion of the first anchor bolt located on the side of the first base plate near the steel brace body. The first nut is located on the side of the first base plate near the steel brace body and is threadedly connected to the first anchor bolt.

[0008] In some possible implementations, there are multiple first anchor plates, which are spaced apart. There are also multiple first anchor bolts, which are connected to multiple first anchor plates respectively.

[0009] In some possible implementations, the first steel brace further includes a first shear key connected to the side of the first base plate away from the steel brace body, and at least a portion of the first shear key is embedded in at least one of the foundation and the ground beam.

[0010] In some possible implementations, the column base includes a second base plate with a second through hole. The steel frame support structure also includes a second anchor plate, a second anchor bolt, and a second nut. The second anchor plate is embedded in the foundation. The second anchor bolt passes through the second through hole and connects to the second anchor plate, with a portion of the second anchor bolt located on the side of the second base plate closer to the column. The second nut is located on the side of the second base plate closer to the column and is threadedly connected to the second anchor bolt.

[0011] In some possible implementations, at least a portion of the first base plate is exposed to the foundation and ground beam. At least a portion of the second base plate is exposed to the foundation, and the second base plate and the first base plate are integrally formed, or the second base plate is embedded in the foundation, or the second base plate and the first base plate are separate components.

[0012] In some possible implementations, the second anchor plate and the first anchor plate are integrally formed when at least a portion of the second base plate is exposed to the foundation.

[0013] In some possible implementations, when at least a portion of the second base plate is exposed to the foundation, the column base also includes a second shear key, which is connected to the side of the second base plate away from the column, and at least a portion of the second shear key is embedded in the foundation.

[0014] In some possible implementations, when the second base plate is embedded in the foundation, the second steel column also includes a first stiffening rib, which is connected to the column body. The side of the first stiffening rib away from the column base is flush with the side of the first base plate away from the first anchor plate.

[0015] In some possible implementations, the first steel brace includes a first flange that is connected to the column. The second steel column also includes a second stiffening rib that is connected to the column, and the side of the second stiffening rib away from the foundation is flush with the side of the first flange away from the foundation and the ground beam.

[0016] In summary, the embodiments of this application have at least the following beneficial effects: In the embodiments of this application, the lower end of the first steel diagonal brace can not only be connected to the second steel column, but also to at least one of the foundation and the ground beam, which reduces the force exerted by the first steel diagonal brace on the second steel column, reduces the risk of damage to the second steel column, and improves the robustness and reliability of the steel frame support structure.

[0025] Figure 1 The diagram shows a steel frame support structure provided in some embodiments of this application. Figure 1 As shown, an embodiment of this application provides a steel frame support structure 100. It can be understood that the steel frame support structure 100 is a three-dimensional load-bearing structure.

[0026] In some examples, such as Figure 1 As shown, the steel frame support structure 100 includes steel columns 110. It is understood that the steel columns 110 are columnar structures, and can be I-beams, Z-beams, square steel, or round steel, etc. The embodiments of this application do not further limit this. Figure 1 As shown, the steel column 110 can extend along the third direction Z.

[0027] Continue to refer to Figure 1 In some examples, there are multiple steel columns 110, including first steel columns 1101 and second steel columns 1102 arranged adjacent to each other. For example, the first steel columns 1101 and second steel columns 1102 can be arranged adjacent to each other along a first direction X, or the first steel columns 1101 and second steel columns 1102 can also be arranged adjacent to each other along a second direction Y.

[0028] The second direction Y is perpendicular or approximately perpendicular to the first direction X. That is, the angle between the second direction Y and the first direction X can be 90°, 88°, or 89°, etc. The third direction Z is perpendicular to the plane containing the first direction X and the second direction Y. That is, the angle between the third direction Z and the plane containing the first direction X and the second direction Y (i.e., the XY plane) can be 90°, 88°, or 89°, etc.

[0029] Multiple steel columns 110 can be arranged in an array along the first direction X and the second direction Y, or multiple steel columns 110 can be arranged in other ways. The embodiments of this application do not further limit the arrangement of multiple steel columns 110.

[0030] Figure 2 This is a schematic diagram showing the positional relationship between the first steel column, the first steel brace, the foundation, and the ground beam, provided for some embodiments of this application. Figure 3 for Figure 2 A magnified view of a portion of region H1. Figure 4 A schematic diagram showing the connection relationship between the first steel column, the first steel brace, and the foundation provided for other embodiments of this application. Figure 5 for Figure 4 A magnified view of a portion of region H2.

[0031] In some examples, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, any steel column 110 includes a column body 111 and a column base 112. The column base 112 is connected to one end of the column body 111 and is connected to the foundation 210.

[0032] For example, the column base 112 and the column body 111 can be integrally formed to improve the reliability of their connection. The foundation 210 can include a natural foundation, a pile foundation, or a pile cap. The embodiments of this application do not further limit the specific form of the foundation 210.

[0033] Understandably, column base 112 may be exposed to and connected to foundation 210, or column base 112 may be embedded in and connected to foundation 210.

[0034] Continue to refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 In some examples, the column base 112 includes a second base plate 1121, on which a second through hole (not shown in the figure) is provided. Understandably, the second base plate 1121 is a flat plate-like structure, the second base plate 1121 is connected to one end of the column 111, and the second through hole penetrates the second base plate 1121 along the thickness direction of the second base plate 1121.

[0035] The steel frame support structure 100 also includes a second anchor plate 151, a second anchor bolt 152, and a second nut 153. The second anchor plate 151 is embedded in the foundation 210. The second anchor bolt 152 passes through a second through hole and is connected to the second anchor plate 151.

[0036] For example, the second anchor bolt 152 and the second anchor plate 151 can be threaded together. For instance, the end of the second anchor bolt 152 near the second anchor plate 151 can be provided with an external thread, and the second anchor plate 151 can be provided with a threaded hole, so that the second anchor bolt 152 can be threadedly connected to the second anchor plate 151.

[0037] Understandably, the threaded connection between the second anchor bolt 152 and the second anchor plate 151 can improve the ease and reliability of their connection.

[0038] Alternatively, the second anchor bolt 152 can also be welded or snapped onto the second anchor plate 151. The embodiments of this application do not further limit the connection method of the second anchor bolt 152 and the second anchor plate 151.

[0039] A portion of the second anchor bolt 152 is located on the side of the second base plate 1121 near the column 111. The second nut 153 is located on the side of the second base plate 1121 near the column 111 and is threadedly connected to the second anchor bolt 152.

[0040] For example, the second anchor bolt 152 located at the end of the second base plate 1121 near the column 111 may be provided with external threads, so that the second nut 153 can be threadedly connected to the second anchor bolt 152.

[0041] Understandably, the second anchor plate 151 is embedded in the foundation 210, one end of the second anchor bolt 152 is connected to the second anchor plate 151, and the other end passes through the second through hole opened on the second base plate 1121 and is connected to the second nut 153, so that the second anchor plate 151, the second anchor bolt 152, the second nut 153 and the second base plate 1121 can form a connection node to connect the column 111 and the foundation 210.

[0042] The second anchor plate 151 and the second nut 153 can limit the movement of the steel column 110 away from the foundation 210 along the third direction Z, and the second anchor plate 151 can also limit the movement of the steel column 110 towards the foundation 210 along the third direction Z. Furthermore, the second anchor bolt 152 passes through the second through hole, thereby limiting the movement of the steel column 110 in the XY plane (the plane containing the first direction X and the second direction Y). This improves the connection reliability between the column 111 and the foundation 210.

[0043] By using the above-described method to connect the steel column 110 and the foundation 210, the convenience and strength of the connection between the two can be improved.

[0044] In some examples, such as Figure 2 and Figure 3 As shown, at least a portion of the second base plate 1121 is exposed to the foundation 210. For example, when at least a portion of the second base plate 1121 is exposed to the foundation 210, the column base 112 can be referred to as an exposed column base.

[0045] like Figure 2 and Figure 3 As shown, when at least a portion of the second base plate 1121 is exposed to the foundation 210, a portion of the second anchor bolt 152 can be embedded in the foundation 210 and connected to the second anchor plate 151, and another portion of the second anchor bolt 152 can be exposed to the foundation 210 and connected through the second through hole and the second nut 153.

[0046] like Figure 2 and Figure 3 As shown, when at least a portion of the second base plate 1121 is exposed to the foundation 210, the number of the second anchor plate 151 and the second anchor bolt 152 can both be multiple, and multiple second anchor bolts 152 and multiple second anchor plates 151 are connected.

[0047] For example, the number of second anchor plates 151 and second anchor bolts 152 can be equal, with multiple second anchor bolts 152 connected to multiple second anchor plates 151 in a one-to-one correspondence. Alternatively, the number of second anchor plates 151 can be less than the number of second anchor bolts 152, with at least two second anchor bolts 152 connected to the same second anchor plate 151. It is understood that the embodiments of this application do not further limit the number of second anchor plates 151 and second anchor bolts 152.

[0048] The number of second anchor bolts 152 and second anchor plates 151 is multiple, which can improve the connection reliability of steel column 110 and ground beam 220.

[0049] Understandably, the number of second through holes can be equal to the number of second anchor bolts 152, with multiple second anchor bolts 152 passing through multiple second through holes in a one-to-one correspondence. Alternatively, the number of second through holes can be less than the number of second anchor bolts 152, with at least two second anchor bolts 152 located within the same second through hole.

[0050] The number of second nuts 153 can be multiple, with at least two second nuts 153 and one second anchor bolt 152 threaded together. For example, ... Figure 2 and Figure 3 As shown, the steel frame support structure 100 may also include a second gasket 154, which is sleeved on the second anchor bolt 152 and located between the second nut 153 and the second base plate 1121.

[0051] Continue to refer to Figure 2 and Figure 3 When at least a portion of the second base plate 1121 is exposed to the foundation 210, the column base 112 may also include reinforcing ribs 1122, and the number of reinforcing ribs 1122 may be multiple.

[0052] Multiple reinforcing ribs 1122 are connected to the side of the second base plate 1121 near the column 111. The multiple reinforcing ribs 1122 are spaced apart circumferentially along the column 111 and are connected to the column 111 respectively. This increases the strength of the portion of the column 111 near the second base plate 1121, thereby improving the robustness and reliability of the steel frame support structure 100.

[0053] For example, the number of reinforcing ribs 1122 can be four, six, or eight, etc. The embodiments of this application do not further limit the number of reinforcing ribs 1122.

[0054] Continue to refer to Figure 2 and Figure 3 When at least a portion of the second base plate 1121 is exposed to the foundation 210, a first filling layer 301 may be provided between the second base plate 1121 and the foundation 210 to serve as a leveling layer.

[0055] For example, the second base plate 1121 can be leveled first, and then the first filling layer 301 can be filled between the second base plate 1121 and the foundation 210. Alternatively, the surface of the first filling layer 301 away from the foundation 210 can be smoothed first, and then the steel column 110 can be installed on the side of the first filling layer 301 away from the foundation 210. Understandably, the second anchor bolt 152 can penetrate the first filling layer 301 to connect the second anchor plate 151 embedded in the ground beam 220.

[0056] Continue to refer to Figure 2 and Figure 3 In some examples, when at least a portion of the second base plate 1121 is exposed to the foundation 210, the column base 112 also includes a second shear key 1123, which is connected to the side of the second base plate 1121 away from the column 111, and at least a portion of the second shear key 1123 is embedded in the foundation 210.

[0057] For example, the second shear key 1123 and the second base plate 1121 can be integrally formed to improve the connection reliability between them. At least a portion of the second shear key 1123 is embedded in the foundation 210, so that the second shear key 1123 can limit the movement of the column 111 in the XY plane, thereby improving the connection reliability between the steel column 110 and the foundation 210.

[0058] In other examples, such as Figure 4 and Figure 5 As shown, the second base plate 1121 is embedded in the foundation 210. For example, when the second base plate 1121 is embedded in the foundation 210, the column base 112 can be referred to as an embedded column base.

[0059] like Figure 4 and Figure 5As shown, when the second base plate 1121 is embedded in the foundation 210, the second anchor bolt 152 and the second nut 153 can both be embedded in the foundation 210.

[0060] When the second base plate 1121 is embedded in the foundation 210, the number of the second anchor plate 151 and the second anchor bolt 152 can both be one, with one second anchor bolt 152 connected to one second anchor plate 151. Alternatively, the number of the second anchor plate 151 and the second anchor bolt 152 can both be multiple, with multiple second anchor bolts 152 connected to multiple second anchor plates 151. The embodiments of this application do not further limit the number of the second anchor plate 151 and the second anchor bolt 152.

[0061] There can be multiple second nuts 153, with at least two second nuts 153 connected to the same second anchor bolt 152. For example, the steel frame support structure 100 may also include a second washer 154, which is fitted onto the second anchor bolt 152 and located between the second nut 153 and the second base plate 1121.

[0062] Continue to refer to Figure 4 and Figure 5 When the second base plate 1121 is embedded in the foundation 210, a second filling layer 302 can be provided between the second base plate 1121 and the foundation 210 to play a leveling role.

[0063] For example, the second base plate 1121 can be leveled first, and then the second infill layer 302 can be filled between the second base plate 1121 and the foundation 210. Alternatively, the surface of the second infill layer 302 away from the foundation 210 can be smoothed first, and then the steel column 110 can be installed on the side of the second infill layer 302 away from the foundation 210. Understandably, the second anchor bolt 152 can penetrate the second infill layer 302 to connect the second anchor plate 151.

[0064] Understandably, when the second base plate 1121 is embedded in the foundation 210, the foundation 210 can limit the movement of the column 111 in the XY plane. At this time, the second shear key 1123 can be omitted to simplify the structure of the steel column 110.

[0065] Refer again Figure 1 In some examples, the steel frame support structure 100 also includes steel beams 120, which connect adjacent first steel columns 1101 and second steel columns 1102. Understandably, there can be multiple steel beams 120, and any one steel beam 120 connects two adjacent steel columns 110 (first steel column 1101 and second steel column 1102).

[0066] For example, when the first steel column 1101 and the second steel column 1102 are arranged adjacent to each other along the first direction X, the steel beam 120 can extend along the first direction X and connect the first steel column 1101 and the second steel column 1102. When the first steel column 1101 and the second steel column 1102 are arranged adjacent to each other along the second direction Y, the steel beam 120 can extend along the second direction Y and connect the first steel column 1101 and the second steel column 1102.

[0067] The steel beam 120 and the steel column 110 (first steel column 1101 and second steel column 1102) can be connected by welding or by a structure such as bolts and nuts. The embodiments of this application do not further limit the connection method between the steel beam 120 and the steel column 110. The steel beam 120 can be an I-beam, a Z-beam, a square steel, or a round steel, etc., and the embodiments of this application do not further limit this.

[0068] Continue to refer to Figure 1 In some examples, the steel beam 120 includes a first steel beam 121 and a second steel beam 122. The first steel beam 121 is adjacent to and spaced apart from the foundation 210, and connects the first steel column 1101 and the second steel column 1102. The second steel beam 122 is located along the third direction Z on the side of the first steel beam 121 away from the foundation 210, and connects the first steel column 1101 and the second steel column 1102.

[0069] Understandably, the first steel beam 121 and the second steel beam 122 are spaced apart along the third direction (Z) and are respectively connected to the steel column 110 to improve the robustness and reliability of the steel frame support structure 100. For example, there can be multiple second steel beams 122, which can be spaced apart along the third direction (Z) on the side of the first steel beam 121 away from the foundation 210 and respectively connected to the steel column 110.

[0070] Continue to refer to Figure 1 In some examples, the steel frame support structure 100 also includes steel diagonal braces 130, and the steel beams 120 can be I-beams, Z-beams, square steel, or round steel, etc. The embodiments of this application do not further limit this. It is understood that the structures of the steel columns 110, steel beams 120, and steel diagonal braces 130 can be the same or different.

[0071] In some examples, the steel brace 130 includes a first steel brace 131 and a second steel brace 132.

[0072] Continue to refer to Figure 1The second steel diagonal brace 132 can be located between the first steel beam 121 and the second steel beam 122. The upper end of the second steel diagonal brace 132 (the end away from the foundation 210) can be connected to the second steel beam 122 and the first steel column 1101. The lower end of the second steel diagonal brace 132 (the end closer to the foundation 210) can be connected to the first steel beam 121 and the second steel column 1102.

[0073] The first steel diagonal brace 131 can be located between the first steel beam 121 and the foundation 210. The upper end of the first steel diagonal brace 131 (the end away from the foundation 210) can be connected to the first steel column 1101 and the first steel beam 121. In some possible implementations, the lower end of the first steel diagonal brace 131 (the end closer to the foundation 210) can be connected to the second steel column 1102.

[0074] Understandably, the extension direction of the steel diagonal brace 130 is inclined relative to the extension directions of the steel column 110 and the steel beam 120, so that the steel diagonal brace 130 can support the steel column 110 and the steel beam 120, thereby improving the strength and reliability of the steel frame support structure 100. For example, the above connection structure can be referred to as a steel frame support structure – central support structure.

[0075] For example, the steel diagonal brace 130 can be connected to the steel column 110 and the steel beam 120 by welding or by bolts and nuts. The embodiments of this application do not further limit the connection method between the steel diagonal brace 130 and the steel column 110 and the steel beam 120.

[0076] Figure 6 This is a schematic diagram illustrating the connection relationship between steel columns, steel beams, and steel braces provided in some embodiments of this application. Figure 7 for Figure 6 A cross-sectional view along the EE direction.

[0077] Understandably, such as Figure 6 and Figure 7 As shown, when the steel brace 130, steel column 110 and steel beam 120 are connected, for example, when the upper end of the first steel brace 131, the first steel column 1101 and the first steel beam 121 are connected, the center line O3 of the steel brace 130, the center line O1 of the steel column 110 and the center line O2 of the steel beam 120 can intersect at one point.

[0078] However, the first steel diagonal brace 131 is located between the first steel beam 121 and the foundation 210. The lower end of the first steel diagonal brace 131 (the end closer to the foundation 210) can only be connected to the second steel column 1102, and cannot be connected to the first steel beam 121 or the second steel beam 122. This will cause the first steel diagonal brace 131 to exert a force on the second steel column 1102, increasing the risk of damage to the second steel column 1102 and affecting the firmness and reliability of the steel frame support structure 100.

[0079] Based on this, in the embodiments of this application, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the lower end of the first steel diagonal brace 131 (the end closest to the foundation 210) is connected to the second steel column 1102, and the lower end of the first steel diagonal brace 131 is connected to at least one of the foundation 210 and the ground beam 220. The ground beam 220 and the foundation 210 are arranged adjacent to each other in the XY plane, and the XY plane is perpendicular to the extension direction (i.e., the third direction Z) of the steel column 110. Understandably, the XY plane is the plane containing the first direction X and the second direction Y, and the extension direction (i.e., the third direction Z) of the steel column 110 can be perpendicular or approximately perpendicular to the XY plane.

[0080] For example, the lower end of the first steel diagonal brace 131 can be connected to the column base 112 of the second steel column 1102, or the lower end of the first steel diagonal brace 131 can also be connected to the column body 111 of the second steel column 1102, or the lower end of the first steel diagonal brace 131 can also be connected to the column body 111 and the column base 112 of the second steel column 1102. The embodiments of this application do not further limit this.

[0081] The ground beam 220 can be a reinforced concrete structure. Alternatively, the ground beam 220 can also be other structures, which are not further limited in the embodiments of this application. The lower end of the first steel diagonal brace 131 can be connected to the foundation 210 (see...). Figure 4 Alternatively, the lower end of the first steel diagonal brace 131 can also be connected to the ground beam 220 (see...). Figure 2 Alternatively, the lower end of the first steel diagonal brace 131 can also be connected to the foundation 210 and the ground beam 220.

[0082] In the embodiments of this application, see Figure 8 , Figure 9 , Figure 10 and Figure 11 The lower end of the first steel diagonal brace 131 can be connected to the second steel column 1102 (see...). Figure 2 , Figure 4 , Figure 8 and Figure 10 It can also be connected to at least one of the foundation 210 and the ground beam 220 (see Figure 2 , Figure 4 , Figure 9 and Figure 11 This reduces the axial force exerted by the first steel diagonal brace 131 on the second steel column 1102, lowers the risk of damage to the second steel column 1102, and improves the robustness and reliability of the steel frame support structure 100.

[0083] Understandably, such as Figure 2 and Figure 4 As shown, the center line O3 of the steel diagonal brace 130 (e.g., the first steel diagonal brace 131) and the center line O1 of the steel column 110 (e.g., the second steel column 1102) can intersect at a point.

[0084] Continue to refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some examples, the first steel brace 131 includes a steel brace body 1311 and a first base plate 1312, the first base plate 1312 being connected to one end of the steel brace body 1311.

[0085] For example, the first base plate 1312 can be a flat plate structure, and the first base plate 1312 and the steel diagonal brace body 1311 can be an integrally formed structure to improve the connection reliability between the two.

[0086] A first through hole (not shown in the figure) is provided on the first base plate 1312. Understandably, the first through hole penetrates the first base plate 1312 along the thickness direction of the first base plate 1312.

[0087] The steel frame support structure 100 also includes a first anchor plate 141, a first anchor bolt 142, and a first nut 143. The first anchor plate 141 is embedded in at least one of the foundation 210 and the ground beam 220. The first anchor bolt 142 passes through a first through hole and is connected to the first anchor plate 141.

[0088] For example, the first anchor bolt 142 and the first anchor plate 141 can be threaded together. For instance, the end of the first anchor bolt 142 near the first anchor plate 141 can be provided with an external thread, and the first anchor plate 141 can be provided with a threaded hole, so that the first anchor bolt 142 can be threadedly connected to the first anchor plate 141.

[0089] Understandably, setting the first anchor bolt 142 and the first anchor plate 141 to be threaded together can improve the convenience and reliability of their connection.

[0090] Alternatively, the first anchor bolt 142 can also be welded or snapped to the first anchor plate 141. The embodiments of this application do not further limit the connection method between the first anchor bolt 142 and the first anchor plate 141.

[0091] A portion of the first anchor bolt 142 is located on the side of the first base plate 1312 near the steel diagonal brace body 1311. The first nut 143 is located on the side of the first base plate 1312 near the steel diagonal brace body 1311 and is threadedly connected to the first anchor bolt 142.

[0092] For example, the first anchor bolt 142 located at the end of the first base plate 1312 near the steel diagonal brace body 1311 may be provided with external threads, so that the first nut 143 can be threadedly connected to the first anchor bolt 142.

[0093] Understandably, the first anchor plate 141 is embedded in at least one of the foundation 210 and the ground beam 220, one end of the first anchor bolt 142 is connected to the first anchor plate 141, and the other end passes through the first through hole opened on the first base plate 1312 and is connected to the first nut 143, so that the first anchor plate 141, the first anchor bolt 142, the first nut 143 and the first base plate 1312 can form a connection node to connect the steel diagonal brace body 1311 to at least one of the foundation 210 and the ground beam 220.

[0094] For example, when the first anchor plate 141 is embedded in the foundation 210, the first steel diagonal brace 131 can be connected to the foundation 210. When the first anchor plate 141 is embedded in the ground beam 220, the first steel diagonal brace 131 can be connected to the ground beam 220. When the first anchor plate 141 is embedded in both the foundation 210 and the ground beam 220, the first steel diagonal brace 131 can be connected to both the foundation 210 and the ground beam 220.

[0095] Understandably, the first anchor plate 141 and the first nut 143 can limit the movement of the first steel diagonal brace 131 away from the foundation 210 and the ground beam 220 along the third direction Z, and the first anchor plate 141 can also limit the movement of the first steel diagonal brace 131 towards the foundation 210 and the ground beam 220 along the third direction Z. Furthermore, the first anchor bolt 142 passes through the first through hole, thereby limiting the movement of the first steel diagonal brace 131 in the XY plane (the plane containing the first directions X and Y). This improves the connection reliability between the first steel diagonal brace 131 and at least one of the foundation 210 and the ground beam 220.

[0096] By using the above-described configuration to connect the first steel diagonal brace 131 to at least one of the foundation 210 and the ground beam 220, the ease and stability of the connection can be improved.

[0097] The first steel diagonal brace 131 is connected to at least one of the foundation 210 and the ground beam 220 via the first anchor plate 141, the first anchor bolt 142, and the first nut 143. This simple force transmission method improves the accuracy and convenience of stress analysis of the connection nodes formed by the first anchor plate 141, the first anchor bolt 142, the first nut 143, and the first base plate 1312, facilitating stress calculation during construction design and improving the safety and reliability of the connection nodes.

[0098] Continue to refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 In some examples, there are multiple first anchor plates 141, which are spaced apart. There are multiple first anchor bolts 142, which are connected to multiple first anchor plates 141 respectively.

[0099] For example, the number of first anchor plates 141 and first anchor bolts 142 can be equal, in which case multiple first anchor bolts 142 are connected to multiple first anchor plates 141 in a one-to-one correspondence. Alternatively, the number of first anchor plates 141 can be less than the number of first anchor bolts 142, with at least two first anchor bolts 142 connected to the same first anchor plate 141. The embodiments of this application do not further limit the number of first anchor plates 141 and first anchor bolts 142.

[0100] Understandably, the number of first through holes can be equal to the number of first anchor bolts 142, with multiple first anchor bolts 142 passing through multiple first through holes in a one-to-one correspondence. Alternatively, the number of first through holes can be less than the number of first anchor bolts 142, with at least two first anchor bolts 142 located within the same first through hole.

[0101] The number of first anchor bolts 142 and first anchor plates 141 is multiple, which can improve the connection reliability between the first steel diagonal brace 131 and at least one of the foundation 210 and ground beam 220.

[0102] There can be multiple first nuts 143, with at least two first nuts 143 threadedly connected to the same first anchor bolt 142. For example, the steel frame support structure 100 may also include a first washer 144, which is fitted onto the first anchor bolt 142 and located between the first nut 143 and the first base plate 1312.

[0103] Continue to refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 For example, the first steel diagonal brace 131 may also include a third stiffening rib 1313, which may be connected to the steel diagonal brace body 1311 and the first base plate 1312. For example, the third stiffening rib 1313 may be integrally formed with the steel diagonal brace body 1311 and the first base plate 1312 to improve the connection reliability between the two.

[0104] The third stiffening rib 1313 can improve the mechanical strength of the first steel diagonal brace 131 and reduce the risk of damage to the first steel diagonal brace 131.

[0105] For example, there can be multiple third stiffening ribs 1313, which are spaced apart on the steel brace body 1311.

[0106] Continue to refer to Figure 2 , Figure 3 , Figure 4 and Figure 5In some examples, the first steel brace 131 further includes a first shear key 1314, which is connected to the side of the first base plate 1312 away from the steel brace body 1311, and at least a portion of the first shear key 1314 is embedded in at least one of the foundation 210 and the ground beam 220.

[0107] For example, the first shear key 1314 and the first base plate 1312 can be integrally formed to improve the reliability of their connection. At least a portion of the first shear key 1314 is embedded in at least one of the foundation 210 and the ground beam 220, so that the first shear key 1314 can limit the movement of the steel diagonal brace body 1311 in the XY plane, thereby improving the reliability of the connection between the first steel diagonal brace 131 and at least one of the foundation 210 and the ground beam 220.

[0108] In some examples, such as Figure 2 and Figure 3 As shown, at least a portion of the first base plate 1312 is exposed to the foundation 210 and the ground beam 220.

[0109] like Figure 2 and Figure 3 As shown, when at least a portion of the first base plate 1312 is exposed to the foundation 210 and the ground beam 220, a portion of the first anchor bolt 142 can be embedded in at least one of the foundation 210 and the ground beam 220 and connected to the first anchor plate 141, and another portion of the first anchor bolt 142 can be exposed to the foundation 210 and the ground beam 220 and connected to the first nut 143 through the first through hole.

[0110] Continue to refer to Figure 2 and Figure 3 When at least a portion of the second base plate 1121 is exposed to the foundation 210, the second base plate 1121 and the first base plate 1312 are integrally formed.

[0111] In other words, when at least a portion of the first base plate 1312 is exposed to the foundation 210 and at least a portion of the second base plate 1121 is exposed to the foundation 210 and the ground beam 220, the column 111 and the steel diagonal brace body 1311 can share the base plate, so as to simplify the structure of the steel frame support structure 100 and improve the construction convenience of the steel frame support structure 100.

[0112] Continue to refer to Figure 2 and Figure 3 In some examples, when at least a portion of the second base plate 1121 is exposed to the foundation 210, the second anchor plate 151 and the first anchor plate 141 are integrally formed.

[0113] In other words, when at least a portion of the first base plate 1312 is exposed to the foundation 210 and at least a portion of the second base plate 1121 is exposed to the foundation 210 and the ground beam 220, the column 111 and the steel diagonal brace body 1311 can share the anchor plate, so as to simplify the structure of the steel frame support structure 100 and improve the construction convenience of the steel frame support structure 100.

[0114] In other examples, such as Figure 4 and Figure 5 As shown, when the second base plate 1121 is embedded in the foundation 210, the second base plate 1121 and the first base plate 1312 are set separately. This arrangement can reduce the mutual influence between the first base plate 1312 and the second base plate 1121.

[0115] like Figure 4 and Figure 5 As shown, when the second base plate 1121 is embedded in the foundation 210, the second anchor plate 151 and the first anchor plate 141 can be installed separately. This arrangement can reduce the mutual influence between the first anchor plate 141 and the second anchor plate 151.

[0116] In some examples, such as Figure 4 and Figure 5 As shown, when the second base plate 1121 is embedded in the foundation 210, the second steel column 1102 also includes a first stiffening rib 113, which is connected to the column body 111. For example, the first stiffening rib 113 and the column body 111 can be an integrally formed structure to improve the reliability of their connection.

[0117] The side of the first stiffening rib 113 away from the column base 112 is flush with the side of the first base plate 1312 away from the first anchor plate 141.

[0118] Understandably, the side of the first stiffening rib 113 away from the column base 112 and the side of the first base plate 1312 away from the first anchor plate 141 can be flush or nearly flush.

[0119] By setting the first stiffening rib 113, the mechanical strength of the column 111 can be improved, and the risk of damage to the column 111 can be reduced. The side of the first stiffening rib 113 away from the column base 112 is flush with the side of the first base plate 1312 away from the first anchor plate 141, which can improve the structural regularity of the steel frame support structure 100.

[0120] In some examples, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the first steel diagonal brace 131 also includes a first flange 131a, which is connected to the column 111.

[0121] For example, both the first steel brace 131 and the second steel column 1102 can be I-beams, and the first flange 131a of the first steel brace 131 can be connected to the second flange 1102a of the second steel column 1102.

[0122] The second steel column 1102 also includes a second stiffening rib 114, which is connected to the column body 111. For example, the second stiffening rib 114 and the column body 111 can be an integrally formed structure to improve the reliability of their connection.

[0123] The side of the second stiffening rib 114 away from the foundation 210 is flush with the side of the first flange 131a away from the foundation 210 and the ground beam 220.

[0124] By setting the second stiffening rib 114, the mechanical strength of the column 111 can be improved, and the risk of damage to the column 111 can be reduced. The side of the second stiffening rib 114 away from the foundation 210 is flush with the side of the first flange 131a away from the foundation 210 and the ground beam 220, which can improve the structural regularity of the steel frame support structure 100.
