Description

Technical Field

[0001] The present invention belongs to the technical field of steel structure installation, and more specifically, relates to a device and method for butting and installing large steel structure columns. Background Art

[0002] As one of the main types of building structures, steel structures play a vital role in modern architecture. Within the steel structure sector, with the rapid development of construction technology and the expansion of building scale, large steel columns are particularly widely used in projects such as super-high-rise buildings, large stadiums, and airport terminals. As the primary load-bearing components of these projects, the accuracy of their installation and positioning is directly related to the stability of the entire building structure.

[0003] In the existing steel structure installation technology, such as the patent document with application number CN202410211148.3, the invention discloses a rapid installation alignment device for steel structure engineering construction, including two telescopic rods, the right end of the telescopic rod is provided with a fixing hole, the left side of the telescopic rod is fixedly connected to a connecting block, and the middle part of the connecting block is provided with a limit hole. The invention clamps the steel structures on both sides in the middle through a clamping mechanism, and the hemispherical seat is adsorbed on the upper surface of the steel structure. Under the action of gravity, the small counterweight block and the large counterweight block keep the infrared rangefinder and the infrared receiving plate in a vertical downward state. When the infrared rangefinder is working and the telescopic rod is shortened to pull the two steel structures, the infrared rangefinder, the infrared receiving plate and the steel structure remain relatively stationary, so that the distance measured by the infrared rangefinder is the actual distance between the steel structures. This solves the problem that the existing steel structure alignment device is relatively cumbersome to operate when performing gap alignment, and is difficult to meet the needs of rapid alignment in existing steel structure engineering construction. However, during use, the invention requires the electromagnetic coil to be energized and the oil supply equipment to be used for oil supply, which is not convenient for high-altitude steel structure construction and fails to solve the problem of high-altitude installation operations of large steel structure columns. For example, the patent document with application number CN202110308307.8 discloses a steel column positioning device and a steel column installation construction method, in which upper and lower lug plates are provided on each side of the upper and lower steel columns, respectively, and the positioner is connected to the lower lug plate, and the horizontal position is adjusted by a jack acting horizontally on the upper steel column; the upper and lower lug plates can be connected by a connecting plate, and the jack acts vertically on the upper steel column to adjust the elevation, thereby realizing positioning welding of the upper and lower steel columns, reducing welding workload, improving construction efficiency, reducing the impact of welding on the steel column base material, and ensuring structural safety. However, the invention uses a jack for plane position and elevation adjustment, which is not suitable for high-altitude operations, and the installation accuracy of the qualitative mounting components is limited.

[0004] Since large steel structure columns are tall and heavy, the installation and construction of steel columns are difficult to operate, and the error after installation and docking is large, which can easily cause the steel columns to become unstable, thereby affecting the stability of the steel structure frame. Therefore, high installation accuracy is required. Most of the existing technologies are aimed at steel structures with smaller steel components and lighter weight, which are not suitable for the installation and docking of large steel structure columns, and cannot be used for high-altitude operations. Summary of the Invention

[0005] In response to the above defects or improvement needs of the prior art, the present invention provides a large-scale steel structure column docking installation and positioning device and method, which connects the positioning component to the steel column through a connecting component and a steel column reserved component, guides and positions the steel column, and fixes the docking component with the positioning component. By screwing in the adjusting bolt in the docking component, a thrust is added to the simple measuring component, which pushes the movable rod to move in a predetermined direction and cause displacement. The scale is observed and recorded through the square outer frame, and the docking position of the lower steel column and the upper steel column is measured and corrected, thereby achieving high-precision docking of the upper and lower steel columns.

[0007] The docking assembly includes a square outer frame with reserved holes and size scales on the outer surface, a simple measuring component installed inside, and an adjusting bolt for adjusting the displacement of the simple measuring component;

[0008] The positioning component includes a standardized square frame, a bottom crossbeam of which is provided with a calibration hole for fixing the docking component, and the calibration distance between the lower steel column and the calibration hole is measured by the docking component, and a correction hole for fixing the docking component is provided on the top crossbeam, and the distance between the upper steel column and the correction hole is corrected according to the calibration distance by the docking component to achieve docking positioning of the upper steel column and the lower steel column; the correction hole and the calibration hole are aligned up and down, and the hole sizes are the same, so as to achieve high-precision docking of the upper steel column and the lower steel column.

[0009] Furthermore, the docking assembly also includes a reserved rod fixed to the bottom of the square outer frame, and the docking assembly is fixed to the positioning assembly through the reserved rod passing through the calibration hole and the correction hole.

[0010] Furthermore, the simple measuring component includes a movable rod with a reserved circular hole, a fixed rod passing through the reserved circular hole to ensure that the movable rod moves in a predetermined direction, and a high-strength spring attached to the fixed rod to ensure that the movable rod cannot move freely.

[0011] Furthermore, the movable rod has a protruding display component, and the display component and the recording scale can be observed through a reserved channel above the square outer frame.

[0012] Furthermore, one end of the adjusting bolt is a sphere with an extended rod to reduce sliding wear on the contact surface between the adjusting bolt and the simple measuring component, and the other end is a bolt with a flange to facilitate screwing.

[0013] Furthermore, the positioning assembly also includes a corner reinforcement member fixed to the internal corner point of the standardized square frame to enhance the stability of the frame and a foldable connecting rod. The foldable connecting rod includes an open spherical sleeve and a long rod with a connecting section, one end of which is connected to the open spherical sleeve.

[0014] Furthermore, the positioning assembly also includes a reserved hole opened on the lower crossbeam of the standardized square frame.

[0015] Furthermore, the steel column reserved assembly includes a reserved transverse plate fixed on the lower steel column to serve as a platform, a reserved diagonal rod serving as a diagonal support for the reserved transverse plate, a reserved fixing rod passing through the reserved opening, and a reserved connecting piece.

[0016] Furthermore, the connecting assembly includes a sleeve with one end screwed and fixed to the reserved connecting piece of the steel column reserved assembly and the other end being an extended rod ball, a fine-tuning connecting device with one end sleeved with the extended rod ball of the sleeve and the other end connected to the long rod with a connecting section of the positioning assembly through a connecting bolt.

[0017] According to another aspect of the present invention, a positioning method for a large-scale steel structure column butt-jointed installation positioning device is provided, which is implemented by applying the large-scale steel structure column butt-jointed installation positioning device described above, and is characterized in that the specific implementation steps are as follows:

[0018] S100: Install the positioning assembly: After the lower steel column is installed and positioned, screw the reserved connector of the steel column reserved assembly into the sleeve of the connecting assembly and pass the reserved fixing rod of the steel column reserved assembly through the reserved hole of the positioning assembly. Then, unfold the foldable connecting rod on the positioning assembly, rotate the foldable connecting rod, connect it to the fine-tuning connector of the connecting assembly, and secure it with the connecting bolts;

[0019] S200: Recording the calibration scale of the lower steel column: Use the docking assembly to record the calibration scale of the lower steel column in the calibration hole of the positioning assembly. Two docking assemblies are installed on a single side of the lower steel column, and a total of 8 calibration scales are recorded. Compare the two calibration scales on the same side. If the scale error is less than the steel structure installation accuracy, it meets the requirements;

[0020] S300: Preliminary adjustment and positioning of the upper steel column: Before docking the large steel structure columns, the upper steel column has been hoisted into place and manually adjusted. After adjustment, the center axis error between the upper and lower steel columns is 1-2 cm, and the gap between the upper and lower steel columns is less than 1 cm. Select two adjacent sides of the upper steel column, set the calibration scale of the docking assembly on the two sides to the calibration scale of the lower steel column corresponding to the same side, and slowly move the upper steel column to closely contact the two selected sides with the corresponding docking assembly ends;

[0021] S400: Full calibration and docking: After positioning the two selected sides of the upper steel column, only tighten the adjustment bolts 104 of the docking components on the other two sides to make the docking components fit tightly against the other two sides, and record the four calibration scales at this time. Compare all calibration scales with the calibration scales one by one for verification. Components with scale errors exceeding the accuracy requirements are corrected by tightening the adjustment bolts 104. When the scale errors are within the accuracy requirements, slowly lower the steel column to complete the docking of the upper and lower steel columns.

[0022] S500: Welding and disassembly: After the welding of the connection between the upper steel column and the lower steel column is completed, the docking assembly, positioning assembly and connection assembly are disassembled in sequence to complete the docking construction of the upper steel column and the lower steel column.

[0023] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0024] 1. A docking assembly of a large steel structure column docking installation and positioning device of the present invention includes multiple components. The adjusting bolt is screwed in, and a thrust is added to the simple measuring component to push the movable rod to move in a predetermined direction to cause displacement, and the scale is observed and recorded through the square outer frame. This method is used to measure and record the calibration scale of the lower steel column through the calibration hole, and then the calibration scale of the upper steel column is corrected through the correction hole to achieve precise docking of the upper and lower steel columns, simplifying the installation and docking construction process of large steel structure columns. The docking assembly is easy to operate and solves the problems of difficult high-altitude installation operations and large installation errors of large steel structure columns compared to traditional manual installation. It can greatly reduce the high-altitude installation operation process, which not only improves the installation efficiency of large steel structure columns, but also improves the installation accuracy of large steel structure columns.

[0025] 2. The docking assembly, connection assembly and positioning assembly of a large steel structure column docking installation and positioning device of the present invention can all be installed and disassembled, which solves the problem that most traditional steel structure connection devices are complex in structure and cannot be reused. The present invention has the function of being reusable, which can reduce the cost of the device and produce better economic benefits.

[0026] 3. A large-scale steel structure column docking installation positioning device of the present invention reserves a 2-3mm gap between the circular hole of the fine-tuning connector of the connecting assembly and the sphere of the extended rod of the sleeve, and reserves a 2-3mm gap between the open spherical sleeve of the foldable connecting rod of the positioning assembly and the long rod with the connecting section. An elastic component is provided, and the connecting end of the elastic component adopts a sphere and a spherical sleeve as a connecting component, which solves the problem of slight deformation of the steel structure connection device under load during the installation of large steel structure columns. The elastic component can offset the load effect after slight deflection when the component is under load, thereby preventing the component from deformation, and protecting the reuse of the component and the installation accuracy of the steel structure column.

[0045] like Figure 1 As shown, an embodiment of the present invention provides a large-scale steel structure column docking installation and positioning device, comprising a docking assembly 1 for correcting deviations in the docking and positioning of steel columns, a positioning assembly 3 for guiding, a connecting assembly 2 for connecting the steel column and the positioning assembly 3, and a steel column reserve assembly 4 for fixing the positioning assembly 3 and connecting the connecting assembly 2. During construction, the installed steel structure column is recorded as the lower steel column, and the steel structure column to be installed is recorded as the upper steel column.

[0046] The positioning assembly includes a calibration opening 305 and a correction opening 304. The docking assembly 1 is moved in a predetermined direction through the calibration opening 305 to measure and record the calibration scale of the lower steel column. The docking assembly 1 is moved in a predetermined direction through the correction opening 304 to adjust and record the calibration scale of the upper steel column. All calibration scales are then compared and verified against the calibration scales, thereby enabling high-altitude docking installation of large steel columns, significantly optimizing the installation process and improving the accuracy of large steel column installation.

[0047] like Figure 2-5 As shown, the docking assembly 1 includes a reserved rod 101, a square outer frame 102, a simple measuring member 103 located inside the square outer frame 102, and an adjusting bolt 104 in contact with the simple measuring member 103.

[0048] A long strip channel is reserved above the square outer frame 102, and size scales (mm scale) are engraved on both sides of the channel for observing and recording the scales. The lower end of the channel is fixed to the reserved rod 101 fixed to the positioning assembly 3; the simple measuring component 103 includes a movable rod 103-1, a fixed rod 103-2 and a high-strength spring 103-3; the movable rod 103-1 has a protruding display part, and the display part and the scale can be observed and recorded through the reserved channel above the square outer frame 102; the movable rod Component 103-1 has a reserved circular hole, and the fixed rod 103-2 passes through the reserved hole to ensure that the movable rod 103-1 moves in a predetermined direction without deviation; the high-strength spring 103-3 is attached to the fixed rod 103-2 to ensure that the movable rod 103-1 cannot move freely; one end of the adjusting bolt 104 is a sphere with an extended rod to reduce the sliding wear of the contact surface between the adjusting bolt 104 and the simple measuring component 103, and the other end is a bolt with a flange for easy screwing.

[0049] The docking assembly 1 includes a pre-installed rod 101, a square outer frame 102, and a simple measuring member 103 that cannot be disassembled. By tightening the adjustment bolt 104 in the docking assembly 1, a thrust is applied to the simple measuring member 103, pushing the movable rod 103-1 in a predetermined direction. The square outer frame 102 is used to observe and record the scale, thereby measuring and correcting the docking position of the lower and upper steel columns.

[0050] like Figure 6 As shown, the connecting component 2 includes a sleeve 201, a fine-tuning connecting device 202 and a connecting bolt 203. One end of the sleeve 201 is tightened and fixed to the steel column reserved component 4, and the other end is a sphere with an extended rod; one end of the fine-tuning connecting device 202 is a component connected to the positioning component 3, and the other end is a circular hole that is socketed with the sphere of the extended rod, so as to facilitate the rotation of the fine-tuning connector 202. A gap of 2 to 3 mm is reserved between the circular hole and the thin rod of the sphere, which serves as an elastic connection and plays a buffering role under the action of external force.

[0051] like Figure 7 As shown, the positioning assembly 3 includes a standardized square frame 301, corner reinforcement members 302 fixed to the internal corners of the standardized square frame 301 to enhance frame stability, and a foldable connecting rod 303. The standardized square frame 301 has a calibration hole 305 and a reserved hole 306 on its lower crossbeam, and a correction hole 304 on its upper crossbeam. The docking assembly 1 is fixed to the positioning assembly 3 via the reserved rod 101 passing through the calibration hole 305 and the correction hole 304.

[0052] The calibration hole 305 and the correction hole 304 are aligned vertically and have the same hole size. The docking assembly 1 is installed in the calibration hole 305, and the distance between the lower steel column and the calibration hole 305 is calibrated. The docking assembly 1 is installed in the correction hole 304, and the distance between the upper steel column and the correction hole 304 is checked according to the calibrated distance between the lower steel column and the calibration hole 305, so as to achieve docking positioning of the upper steel column and the lower steel column;

[0053] like Figure 8 As shown, the foldable connecting rod 303 includes an open spherical sleeve 303-1 and a long rod 303-2 with a connecting section; the foldable connecting rod 303 is folded and unfolded through the open spherical sleeve 303-1, which is convenient for construction and transportation; one end of the long rod 303-2 with a connecting section is a sphere, and its spherical end is connected to the open spherical sleeve 303-1. The sphere facilitates the rotation of the long rod 303-2 with a connecting section, and a 2-3 mm gap is reserved between the open spherical sleeve 303-1 and the long rod, which serves as an elastic connection and plays a buffering role under the action of external force; the other end of the long rod 303-2 with a connecting section is a connecting end with a reserved hole, which is connected to the fine-tuning connector 202 in the connecting component 2 through an adjusting bolt 104, connecting the positioning component 3 to the steel column.

[0054] The steel column reserved assembly 4 includes a reserved diagonal rod 401 fixed to the lower steel column, a reserved transverse plate 402, a reserved fixing rod 403, and a reserved connecting piece 404. The reserved diagonal rod 401 serves as a diagonal brace to fix the reserved transverse plate 402, and the reserved transverse plate 402 serves as a platform to support various components and facilitate high-altitude operations. The reserved fixing rod 403 passes through the reserved hole 306 on the positioning assembly 3 to fix the positioning assembly 3 and prevent the positioning assembly 3 from shifting. The reserved connecting piece 404 on the lower steel column is connected to the sleeve 201 of the connecting assembly 2 to fix the positioning assembly 3 to the lower steel column.

[0055] This embodiment of the present invention effectively secures the positioning assembly 3 and uses the docking assembly 1 to calibrate the distance between the calibration hole 305 on the positioning assembly 3 and the lower steel column. This adjusts the calibration distance between the correction hole 306 on the positioning assembly 3 and the upper steel column to the calibrated distance, ultimately completing the docking installation of the large steel structure column. This device simplifies precision control during the installation process and improves the efficiency of large steel structure column installation.

[0056] like Figure 9 As shown, an embodiment of the present invention provides a method for positioning a large steel structure column butt-jointed installation positioning device, which is implemented by applying the above-mentioned large steel structure column butt-jointed installation positioning device.

Then unfold the foldable connecting rod on the positioning assembly, rotate the foldable connecting rod, connect it to the fine-tuning connecting device of the connecting assembly, and fix it with the connecting bolts.

[0058] S200: Record the calibration scale of the lower steel column: Use the docking component to record the calibration scale of the lower steel column in the calibration hole of the positioning component. Two docking components are installed on a single side of the lower steel column, and a total of 8 calibration scales are recorded. Compare the two calibration scales on the same side. If the scale error is less than the steel structure installation accuracy, it meets the requirements.

[0059] S300: Preliminary Adjustment and Positioning of Upper Steel Columns: Before docking large steel columns, the upper steel columns are hoisted into place and manually adjusted. After adjustment, the center axis error between the upper and lower steel columns is 1-2 cm, and the gap between the upper and lower steel columns is less than 1 cm. Select two adjacent sides of the upper steel column, set the calibration scales of the docking components on these two sides to the calibration scales corresponding to the same side of the lower steel column, and slowly move the upper steel column to align the two selected sides with the corresponding docking component ends.

[0060] S400: Comprehensive Calibration and Docking: After positioning the two selected sides of the upper steel column, tighten only the adjustment bolts 104 of the docking assemblies on the other two sides to ensure they are firmly in contact with the other two sides. Record the four calibration marks at this point. Verify all calibration marks against the calibration scale. Components with scale errors exceeding the required accuracy are corrected by tightening the adjustment bolts 104. Once the scale errors are within the required accuracy, slowly lower the steel column to complete the docking of the upper and lower columns.

[0061] S500: Welding and disassembly: After the welding of the connection between the upper steel column and the lower steel column is completed, the docking assembly, positioning assembly and connection assembly are disassembled in sequence to complete the docking construction of the upper steel column and the lower steel column.

[0062] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

After adjustment, the center axis error between the upper and lower steel columns is 1-2 cm, and the gap between the upper and lower steel columns is less than 1 cm. Select two adjacent sides of the upper steel column, set the calibration scales of the docking components on the two sides to the calibration scales corresponding to the same side of the lower steel column, and slowly move the upper steel column to closely contact the two selected sides with the corresponding docking component ends; S400: Full calibration and docking: After positioning the two selected sides of the upper steel column, only the adjustment bolts of the docking components on the other two sides are tightened to make the docking components close to the other two sides, and the four calibration scales at this time are recorded. All calibration scales are compared with the calibration scales one by one for verification. Components with scale errors exceeding the accuracy requirement are corrected by tightening the adjustment bolts. When the scale errors are within the accuracy requirements, the steel column is slowly lowered to complete the position docking of the upper and lower steel columns; S500: Welding and disassembly: After the welding of the connection between the upper steel column and the lower steel column is completed, the docking assembly, positioning assembly and connection assembly are disassembled in sequence to complete the docking construction of the upper steel column and the lower steel column.
