Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a limiting and adjusting structure for large cantilever steel columns. Background Technology

[0002] During the construction of steel structures, the accuracy of steel column hoisting and positioning is crucial to the quality and safety of the structure. Due to the large mass of steel columns, their installation is a dynamic process of hoisting and positioning simultaneously. Currently, steel column installation is generally carried out using hoisting equipment and auxiliary guy ropes for adjustment, and then secured with anchor bolts.

[0003] The existing technical solutions mentioned above have the following drawbacks: when the cantilever height of the steel column is high and the cantilever time is long, it is difficult to ensure the lateral stability of the steel column by using guy ropes. Utility Model Content

[0004] This application provides a limiting and adjusting structure for large cantilever steel columns to increase lateral stability and improve the installation quality of the steel columns.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0006] A limiting and adjusting structure for large cantilever steel columns, wherein the steel column is composed of a web and flanges, two flanges are provided and symmetrically arranged on both sides of the web, and multiple steel columns are spaced apart, characterized in that: the limiting and adjusting structure includes a weak axis connecting beam, the weak axis connecting beam is fixed between two adjacent steel columns, a constraint support assembly is connected to the weak axis connecting beam, one end of the constraint support assembly is connected to the steel column, and a bidirectional adjusting device is connected between the two steel columns;

[0007] The constraint support assembly includes a telescopic rod and a support rod. One end of the telescopic rod is inserted into and threaded into the support rod. The ends of the telescopic rod and the support rod that are far apart are both fixed with end plates. The two end plates are respectively fixed to the weak axis connecting beam and the steel column.

[0008] By adopting the above technical solutions, the weak-axis connecting beam can connect multiple steel columns to form a whole, which can enhance the stability of the weak-axis part of the steel column. The adjustable constraint support component can correct the offset of multiple steel column groups and ensure the overall stability of the steel column group. The bidirectional adjustment device can realize the local adjustment and reinforcement of steel column offset through the bracing method. Through the cooperation of the weak-axis connecting beam, constraint support component and bidirectional adjustment device, the deviation of the steel column can be adjusted and the steel column can be limited. This can increase the lateral stability of the cantilever steel column, ensure the safety and stability of the temporary fixation of the large cantilever steel column during the construction stage, and improve the installation quality of the steel column.

[0009] Optionally, a connecting plate is fixedly connected to the end plate, and the two connecting plates are respectively fixed to the weak axis connecting beam and the steel column.

[0010] By adopting the above technical solution, the constraint support assembly is connected between the weak axis connecting beam and the steel column through the connecting plate, which facilitates the disassembly and assembly of the constraint support assembly by the workers during the construction phase.

[0011] Optionally, the constraint support assembly includes a telescopic rod and a support rod. One end of the telescopic rod is inserted and threaded into the support rod. Both ends of the telescopic rod and the support rod that are far apart are fixedly connected to an end plate. A connecting plate is fixedly connected to the end plate. The two connecting plates are respectively fixedly connected to the weak axis connecting beam and the steel column.

[0012] By adopting the above technical solution, the telescopic rod of the constraint support assembly can be rotated to change the length of the telescopic rod extending out of the support rod, thereby adjusting the offset of the steel column. At the same time, the threaded connection between the telescopic rod and the support rod has a self-locking characteristic, which can enhance the overall stability of the steel column group and improve the installation quality of the steel column. The constraint support assembly is connected between the steel column and the connecting beam connecting plate through the connecting plate, which facilitates the disassembly and assembly of the constraint support assembly by the workers during the construction phase.

[0013] Optionally, a pair of struts connects the two steel columns.

[0014] By adopting the above technical solution, and arranging struts according to the weak points of the steel column group, with the struts set at the edge and corner columns, the overall stability of the steel column group can be increased and the quality of steel column installation can be improved.

[0015] Optionally, each of the two adjusting rods has an adjusting connecting piece fixedly connected to one end away from the hydraulic rod, and the two adjusting connecting pieces are respectively fixedly connected to the two steel columns.

[0016] By adopting the above technical solution, the bidirectional adjustment device is connected between two steel columns by adjusting the connecting piece, which makes it convenient for workers to disassemble and assemble the bidirectional adjustment device during the construction phase.

[0017] Optionally, a connecting beam connecting piece for connecting the end plate is fixedly connected to the weak axis connecting beam.

[0018] By adopting the above technical solution, the connecting plate of the connecting beam facilitates the connection of the constraint support component to the weak axis connecting beam during construction, increases the structural strength at the connection between the constraint support component and the weak axis connecting beam, and ensures that the constraint support component can correct the displacement of the steel column group.

[0019] Optionally, the bidirectional adjustment device includes two adjustment rods, which are connected together by a hydraulic rod. The ends of the two adjustment rods away from the hydraulic rod are respectively fixed to the two steel columns.

[0020] By adopting the above technical solution, controlling the extension and retraction of the hydraulic rod of the bidirectional adjustment device can drive the adjustment rod and the steel column to move, thereby adjusting the deviation of the steel column and limiting its position. This increases the lateral stability of the cantilever steel column, ensures the safety and stability of the temporary fixation of the large cantilever steel column during the construction phase, and improves the installation quality of the steel column.

[0021] Optionally, the adjusting connecting piece has a through hole for the fixing bolt to pass through.

[0022] By adopting the above technical solution, the through holes opened on the adjustment connecting piece make it easy for workers to use bolts to fix or remove the bidirectional adjustment component.

[0023] Optionally, the cross-section of the weak-axis connecting beam is I-shaped.

[0024] By adopting the above technical solutions, the overall structural strength of the connecting beam joint can be increased, and the stability of the weak axis part of the steel column can be enhanced.

[0025] In summary, this application has the following technical effects:

[0026] 1. By setting up a weak axis connecting beam, a constraint support assembly and a two-way adjustment device, the deviation of the steel column can be adjusted and the steel column can be limited, which can increase the lateral stability of the cantilever steel column, ensure the safety and stability of the temporary fixation of the large cantilever steel column during the construction phase, and improve the installation quality of the steel column.

[0035] The present application will be further described in detail below with reference to the accompanying drawings.

[0036] This application discloses a limiting and adjusting structure for a large cantilever steel column, referring to... Figure 1 and Figure 2 The steel column 1 is composed of a web 11 and a flange 12. There are two flanges 12, which are located on both sides of the length of the web 11. The cross-section of the steel column 1 is I-shaped. Multiple steel columns 1 are set at intervals on the construction site. One end of the steel column 1 is connected to another steel column 1. The two connected steel columns 1 are connected to a common assembly 14 at one end. The assembly 14 consists of six pieces. The two ends of the six assembly pieces 14 are respectively welded to the side wall of the flange 12 of the two steel columns 1 away from the web.

[0037] Reference Figure 2 and Figure 3 The limiting and adjusting structure includes shear studs 13 welded to the steel column 1. Multiple shear studs 13 are spaced apart along the length of the web 11 and the flange 12. A weak axis connecting beam 2 connects two horizontally adjacent steel columns 1 with their webs 11 facing each other. The cross section of the weak axis connecting beam 2 is I-shaped. The weak axis connecting beam 2 is horizontally arranged and its two ends are welded to the webs 11 of the two steel columns 1 respectively. A connecting beam connecting piece 21 is welded to the bottom of the middle section of the weak axis connecting beam 2 along its length.

[0038] Reference Figure 1 and Figure 4 A constraint support assembly 3 is connected to the connecting beam connecting piece 21. The constraint support assembly 3 includes a telescopic rod 33 and a support rod 34. One end of the telescopic rod 33 is machined into a threaded section and inserted into the support rod 34. The threaded section of the telescopic rod 33 is threaded to the support rod 34. The axes of the telescopic rod 33 and the support rod 34 coincide. An end plate 32 is welded to the ends of the telescopic rod 33 and the support rod 34 that are far apart. A connecting plate 31 for passing through fixing bolts is welded to the side of the end plate 32 away from the telescopic rod 33 or the support rod 34. The connecting plate 31 at one end of the constraint support assembly 3 is fixed to the connecting beam connecting piece 21 by bolts, and the connecting plate 31 at the other end is fixed to the adjacent steel column 1 by bolts.

[0039] Reference Figure 1 and Figure 5 A pair of struts 4 are connected between two horizontally adjacent steel columns 1 with their flanges 12 facing each other. The two ends of the pair of struts 4 are respectively welded to the opposite side of the flanges 12 of the two steel columns 1. A bidirectional adjustment device 5 is connected between two steel columns 1 with their webs and flanges 12 not facing each other. The bidirectional adjustment device 5 includes two adjustment rods 51 with their axes overlapping. The two adjustment rods 51 are connected to a hydraulic rod 52 at their close ends. The two adjustment rods 51 are each welded to an adjustment connecting piece 53 at their far ends. The adjustment connecting piece 53 has a through hole for the fixing bolt to pass through. The adjustment connecting piece 53 at one end of the bidirectional adjustment device 5 is fixed to the web 11 of one steel column 1 by bolts, and the adjustment connecting piece 53 at the other end is fixed to the flange 12 of the other steel column 1 by bolts.

[0040] When this limiting and adjusting structure is used, the weak axis connecting beam 2 can connect multiple steel columns 1 to form a whole, which can enhance the stability of the weak axis part of the steel column 1. The adjusting constraint support component 3 can correct the offset of the group of multiple steel columns 1, ensuring the overall stability of the group of steel columns 1. The bidirectional adjustment device 5 realizes the local adjustment and strengthening of the offset of the steel column 1 through the method of bracing. Through the cooperation of the weak axis connecting beam 2, the constraint support component 3 and the bidirectional adjustment device 5, the offset of the steel column 1 can be adjusted, and the steel column 1 can be limited. This can increase the lateral stability of the cantilever steel column 1, ensure the safety and stability of the temporary fixation of the large cantilever steel column 1 during the construction stage, and improve the installation quality of the steel column 1.

[0041] The shear studs 13 can increase the bond between the steel column 1 and the concrete during the pouring of the outer concrete, thus improving the construction quality. The steel columns 1 are connected by the assembly parts 14, which can increase the structural strength of the connection points of the steel columns 1, ensure the safety and stability of the large cantilever steel columns 1 during the construction phase, and improve the installation quality of the steel columns 1.

[0042] The cross-section of the connecting beam connecting piece 21 is I-shaped, which can increase the overall structural strength of the connecting beam connecting piece 21 and enhance the stability of the weak axis part of the steel column 1. The connecting beam connecting piece 21 facilitates the connection of the connecting plate 31 of the constraint support component 3 to the weak axis connecting beam 2 during construction, increases the structural strength at the connection between the constraint support component 3 and the weak axis connecting beam 2, and ensures that the constraint support component 3 can correct the offset of the steel column group 1.

[0043] When using this limit adjustment structure, rotating the telescopic rod 33 of the constraint support assembly 3 changes the length of the telescopic rod 33 extending out of the support rod 34, which can adjust the offset of the steel column 1. At the same time, the threaded connection between the telescopic rod 33 and the support rod 34 has a self-locking characteristic, which can enhance the overall stability of the steel column 1 group and improve the installation quality of the steel column 1. The constraint support assembly 3 is connected between the steel column 1 and the connecting beam connecting piece 21 through the connecting plate 31, which makes it convenient for workers to disassemble and assemble the constraint support assembly 3 during the construction phase.

[0044] When using this limiting and adjusting structure, the support rods 4 are arranged according to the weak points of the steel column group 1. The support rods 4 are set at the side columns and corner columns, which can increase the overall stability of the steel column group 1 and improve the installation and construction quality of the steel column 1.

[0045] When this limit adjustment structure is used, controlling the extension and retraction of the hydraulic rod 52 of the bidirectional adjustment device 5 enables the hydraulic rod 52 to drive the adjustment rod 51 and the steel column 1 to move, thereby adjusting the deviation of the steel column 1 and limiting the steel column 1, increasing the lateral stability of the cantilever steel column 1, ensuring the safety and stability of the temporary fixation of the large cantilever steel column 1 during the construction phase, and improving the installation quality of the steel column 1. The bidirectional adjustment device 5 is connected between the two steel columns 1 through the adjusting connecting piece 53. The through hole opened on the adjusting connecting piece 53 makes it easy for workers to fix or remove the bidirectional adjustment component 5 with bolts, making it easy for workers to disassemble and assemble the bidirectional adjustment component 5 during the construction phase.

[0046] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
