Description

Technical Field

[0001] This application relates to the field of segmented steel column installation, connection and hoisting structure technology, and in particular to a segmented steel column installation, connection and hoisting structure. Background Technology

[0002] During the construction of steel structures, due to the large weight and length of the steel columns, and considering issues such as transportation and hoisting, the steel columns need to be disassembled into sections and connected in the air during installation.

[0003] The existing steel columns are too tall, making one-time hoisting difficult. Therefore, an aerial docking method is adopted. Aerial docking requires strict control of verticality and horizontal axis to ensure that the steel columns are vertical as a whole and that all the steel columns in the project are on the same axis. At the same time, the structural strength between the steel columns must be enhanced. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a segmented steel column installation and connection hoisting structure, which overcomes the deficiencies of existing technologies. It aims to solve the problem that some existing engineering steel columns are too high, making one-time hoisting difficult. Therefore, an aerial docking method is adopted. Aerial docking requires strict control of verticality and horizontal axis to ensure that the steel columns are vertical as a whole and that all steel columns in the entire project are on the same axis. At the same time, it is also necessary to strengthen the structural strength between the steel columns.

[0005] To achieve the above objectives, this application provides the following technical solution: a segmented steel column installation and connection hoisting structure, including a foundation, four sets of steel columns installed above the foundation, a connecting assembly between the four sets of steel columns and the foundation, the connecting assembly including a fixing plate, four sets of mounting screws on the top of the fixing plate, each of the four sets of mounting screws being threaded with a nut, a connecting sleeve inside the fixing plate extending downwards through the fixing plate, threaded holes at the bottom of each of the four sets of steel columns, threaded holes inside the threaded holes matching the four sets of mounting screws, structural steel sections on the top of the four sets of steel columns, four connecting assemblies on the top of the structural steel sections, and through holes at positions corresponding to the four sets of connecting assemblies on the top of the structural steel sections.

[0006] By adopting the above technical solution, and by setting up a foundation, four sets of steel columns are inserted into the inside of the connecting sleeve during installation. Then, the threaded holes are used to align the mounting bolts to achieve the effect of correcting the position of the steel columns during installation, preventing positional displacement during installation. After subsequent installation, the four sets of mounting bolts can further improve the stability and structural strength of the connection between the steel columns and the connecting components. The setting of the steel profile can also further enhance the structural strength and tightness of the connection between the two sets of steel columns, and can also achieve a fixed connection between the four sets of steel columns. This setting can make the connection between the two sets of steel columns tighter and more vertical, reduce the impact of skew on the steel column connection, and avoid displacement.

[0007] As a preferred technical solution of this application, a fixing sleeve is provided at the top of each of the four groups of steel columns, and a reinforcing rod is provided between each of the four groups of steel columns. The bottom of the reinforcing rod is fixedly connected to one side of the connecting assembly, and the top of the reinforcing rod is fixedly connected to the outside of the fixing sleeve.

[0008] By adopting the above technical solution and setting a fixed sleeve, the structural strength between multiple sets of steel columns can be further guaranteed by the set reinforcing rod during use. The fixed sleeve can achieve the connection effect between the bottom of the steel section and the top of the steel column, and the fixing effect of the reinforcing rod can be further improved.

[0009] As a preferred technical solution of this application, a straightening block is provided inside the connecting sleeve, and the straightening block is located at the bottom of the steel column.

[0010] By adopting the above technical solution and setting the correction block, the stability of the steel column inside the connecting sleeve can be improved during use, and the occurrence of tilting can be reduced.

[0011] As a preferred technical solution of this application, the connecting sleeve is provided with multiple sets of pads inside.

[0013] As a preferred technical solution of this application, each of the multiple sets of mounting screws is rotatably connected to a stop block, and each stop block is provided with a stabilizing ring on its top.

[0014] By adopting the above technical solution and setting the stop block, it can cooperate with the nut during use to achieve the effect of fixing the connecting plate, thus limiting the height of the connecting plate.

[0015] As a preferred technical solution of this application, the steel profile has an installation groove inside, and multiple sets of connecting rods are arranged inside the installation groove.

[0016] By adopting the above technical solution and setting the installation groove, the structural strength of the steel section can be improved and the stability of the structure can be enhanced during use.

[0017] As a preferred technical solution of this application, lifting blocks are provided on the outside of the steel section and on both sides of the multiple sets of steel columns, and mounting holes are provided inside the lifting blocks.

[0018] By adopting the above technical solution and setting up lifting blocks, it is easier and more stable for workers to lift steel sections and steel columns, thereby improving lifting efficiency.

[0019] As a preferred technical solution of this application, the size of the steel column matches the internal size of the connecting sleeve.

[0020] By adopting the above technical solution and matching the size of the steel column with the internal size of the connecting sleeve, the stability of the connection between the steel column and the connecting sleeve can be improved.

[0021] The beneficial effects of this application are:

[0022] 1. By setting up a foundation, during installation, four sets of steel columns are inserted into the inside of the connecting sleeve. Then, the threaded holes are used to align the mounting bolts, achieving the effect of correcting the position of the steel columns during installation and preventing positional deviation. After subsequent installation, the four sets of mounting bolts can further improve the stability and structural strength of the connection between the steel columns and the connecting components. The setting of the steel profile can also further enhance the structural strength and tightness of the connection between the two sets of steel columns, and can also achieve a fixed connection between the four sets of steel columns. This setting can make the connection between the two sets of steel columns tighter and more vertical, reducing the impact of skew on the steel column connection and avoiding deviation.

[0023] 2. By setting a fixed sleeve, the structural strength between multiple sets of steel columns can be further guaranteed by the set reinforcing rod during use. The fixed sleeve can realize the connection effect between the bottom of the steel section and the top of the steel column, and the fixing effect of the reinforcing rod can be further improved.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Reference Figure 1-4 A segmented steel column installation and connection hoisting structure includes a foundation 1, four sets of steel columns 2 installed above the foundation 1, and a connecting assembly 3 between the four sets of steel columns 2 and the foundation 1. The connecting assembly 3 includes a fixing plate 301, four sets of mounting screws 302 on the top of the fixing plate 301, and nuts 303 threadedly connected to the outside of each of the four sets of mounting screws 302. A connecting sleeve 304 is provided inside the fixing plate 301, extending downward through the fixing plate 301. Threaded holes 203 are provided at the bottom of each of the four sets of steel columns 2, and threaded holes 203 inside the threaded holes 203 that match the four sets of mounting screws 302. A steel section 4 is provided at the top of the four sets of steel columns 2, and four sets of connecting assemblies 3 are provided at the top of the steel section 4. Through holes 401 are provided at the top of the steel section 4 corresponding to the four sets of connecting assemblies 3. A straightening block 306 is provided inside the connecting sleeve 304, located at the bottom of the steel column 2.

[0031] By setting up foundation 1, during installation, four sets of steel columns 2 are inserted into the connecting sleeve 304. The threaded holes 203 are then used to align the mounting screws 302, achieving a positional correction effect for the steel columns during installation and preventing positional misalignment. After subsequent installation, the four sets of mounting screws 302 further enhance the stability and structural strength of the connection between the steel columns 2 and the connecting assembly 3. The steel profile 4 further strengthens the structural strength and tightness of the connection between the two sets of steel columns 2, and also achieves a fixed connection between the four sets of steel columns 2. This arrangement makes the connection between the two sets of steel columns 2 tighter and more perpendicular, reducing the impact of skew on the connection and preventing misalignment. By setting up the correction block 306, the stability of the steel columns 2 inside the connecting sleeve 304 is improved during use, reducing the occurrence of tilting.

[0032] Reference Figure 1 Each of the four sets of steel columns 2 is equipped with a fixing sleeve 501 at its top, and a reinforcing rod 5 is installed between each of the four sets of steel columns 2. The bottom of the reinforcing rod 5 is fixedly connected to one side of the connecting component 3, and the top of the reinforcing rod 5 is fixedly connected to the outside of the fixing sleeve 501. Multiple sets of pads 305 are installed inside the connecting sleeve 304. An installation groove 402 is opened inside the steel section 4, and multiple sets of connecting rods 403 are installed inside the installation groove 402. By setting the fixing sleeve 501, the reinforcing rod 5 can further ensure the structural strength between the multiple sets of steel columns 2 during use. The fixing sleeve 501 can achieve the connection effect between the bottom of the steel section 4 and the top of the steel column 2, and the fixing effect of the reinforcing rod 5 can be further improved. The pads 305 can be used to correct the angle when the angle of the steel column 2 changes inside the connecting sleeve 304. By setting the installation groove 402, the structural strength of the steel section 4 can be improved and the stability of the structure can be enhanced during use.

[0033] Reference Figure 1Each of the multiple sets of mounting screws 302 is rotatably connected to abutment blocks 307, and each abutment block 307 has a stabilizing ring 308 on its top. By setting abutment blocks 307, they can cooperate with nuts 303 during use to fix the connecting plate 202, thus limiting the height of the connecting plate 202. Lifting blocks 201 are provided on the outside of the steel profile 4 and on both sides of the multiple sets of steel columns 2, and each lifting block 201 has mounting holes inside. By setting lifting blocks 201, it is easier and more stable for workers to lift the steel profile 4 and steel columns 2 during use, improving lifting efficiency. The size of the steel column 2 matches the internal size of the connecting sleeve 304. Matching the size of the steel column 2 to the internal size of the connecting sleeve 304 improves the stability of the connection between the steel column 2 and the connecting sleeve 304.

[0034] Working principle: By setting up the foundation 1, during installation, four sets of steel columns 2 are inserted into the inside of the connecting sleeve 304. Then, the threaded holes 203 are used to align the mounting screws 302 to achieve the effect of correcting the position of the steel columns during installation, preventing positional displacement during installation. After subsequent installation, the four sets of mounting screws 302 can further improve the stability and structural strength of the connection between the steel columns 2 and the connecting components 3. The setting of the steel section 4 can also further enhance the structural strength and tightness of the connection between the two sets of steel columns 2, and can also achieve a fixed connection between the four sets of steel columns 2. This setting can make the connection between the two sets of steel columns 2 tighter and more vertical, reducing the impact of skew on the connection of the steel column 2 and avoiding displacement. By setting the fixing sleeve 501, the setting of the reinforcing rod 5 can further ensure the structural strength between the multiple sets of steel columns 2 during use. The setting of the fixing sleeve 501 can achieve the connection effect between the bottom of the steel section 4 and the top of the steel column 2, and the fixing effect of the reinforcing rod 5 can be further improved.

[0035] Among them, by setting the correction block 306, the stability of the steel column 2 inside the connecting sleeve 304 can be improved during use, and the occurrence of tilting can be reduced. The shim 305 can be set to correct the angle when the angle of the steel column 2 inside the connecting sleeve 304 changes during use.

[0036] Meanwhile, by setting the stop block 307, it can cooperate with the nut 303 during use to achieve the effect of fixing the connecting plate 202, thus limiting the height of the connecting plate 202;

[0037] In addition, by setting the installation groove 402, the structural strength of the steel section 4 can be improved and the stability of the structure can be enhanced during use; by setting the lifting block 201, it is easier and more stable for workers to lift the steel section 4 and the steel column 2 during use, thus improving the lifting efficiency; by setting the size of the steel column 2 to match the internal size of the connecting sleeve 304, the stability of the connection between the steel column 2 and the connecting sleeve 304 can be improved.
