Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to an automatic steel column alignment device for building construction and a construction method. Background Art

[0002] As the core load-bearing member of the modern building system, the installation accuracy of steel structures directly determines the overall safety and stability of the building structure. During the butt joint construction of steel columns, three-dimensional alignment of the spatial position, axis alignment, and perpendicularity of the upper and lower segments is required to ensure the precise docking of the load transfer path. However, restricted by factors such as the excessive self-weight of the steel column and the complex high-altitude operation conditions, manual alignment has prominent problems such as low efficiency, large fluctuations in accuracy, and high safety risks, making it difficult to meet the technical requirements of high-efficiency and precise construction for modern steel structure projects.

[0003] At present, the commonly used alignment process is "temporary earplate welding - mechanical jacking", that is, multiple groups of earplates are welded at the butt joint end of the steel column, and a temporary fixing structure is formed by bolt-connecting double splints. Multiple construction workers operate hydraulic jacks to apply thrust to the steel column and make multiple adjustments in combination with measuring instruments. However, this method has limitations: on the one hand, the earplate welding and subsequent cutting processes will damage the surface integrity of the steel column base material, form a heat-affected zone and produce repair welding scars, reducing the durability of the component and affecting the aesthetics of the steel column; on the other hand, the manual operation has poor coordination, and the alignment process is prone to repeated oscillations, making it difficult to achieve precise fine-tuning; in addition, in the hoisting operation environment, due to the large volume and heavy weight of the steel column, during the alignment process by manual, not only the labor intensity is large, time-consuming and laborious, with low alignment efficiency, but also safety hazards are easily generated.

[0004] Based on this, it is necessary to research an automatic steel column alignment device for building construction and a construction method. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an automatic steel column alignment device for building construction and a construction method, which effectively solves the problems of poor coordination of existing manual operations, inaccurate positioning, time-consuming and laborious, and low efficiency.

[0006] To achieve the above object, the technical solution adopted by the present invention is: an automatic steel column correction device for building construction, including an arc-shaped connecting piece, an upper sleeve body, a lower sleeve body and a guiding and positioning component. The upper sleeve body and the lower sleeve body both include at least two groups of arc-shaped connecting pieces. At least two groups of arc-shaped connecting pieces are connected end to end correspondingly to form an annular sleeve body. The guiding and positioning component is arranged between the upper and lower sleeve bodies. The guiding and positioning component includes a connecting rope, a positioning rod and a guiding seat. The positioning rod is fixed on the upper sleeve body along the circumference, and a connecting ring is arranged at the bottom of the positioning rod. The guiding seat is fixed on the lower sleeve body along the circumference. The inner cavity of each guiding seat is hollow and is coaxial with the positioning rod respectively. The inner diameter of the guiding seat is adapted to the diameter of the positioning rod so that the positioning rod is inserted into the guiding seat in a matching manner. One end of the connecting rope is connected to a winding device, and the other end passes through the rear end of the guiding seat and is fixedly connected to the connecting ring.

[0007] Further, the upper part of the guiding seat is of an open structure, and the lower part is in a straight cylinder shape. The positioning rod can be properly sleeved in the straight cylinder structure at the lower part of the guiding seat.

[0008] Further, the bottom of the positioning rod is of an arc-shaped structure, and a groove is opened in the middle of the arc-shaped structure. The connecting ring is fixedly installed in the groove.

[0009] Further, ear plates are respectively arranged at the head and tail ends of the arc-shaped connecting piece, and a screw rod is threadedly connected in the middle of the connecting piece. The inner end of the screw rod extends to the middle of the sleeve body and is fixed with an arc-shaped plate to fixedly sleeve the sleeve body on the steel column.

[0010] Further, positioning seats are fixed on the three groups of arc-shaped connecting pieces forming the upper sleeve body along the circumference. The screw rod on the upper sleeve body is threadedly connected in the positioning seat, and the inner end extends to the middle of the upper sleeve body and is fixedly connected with the arc-shaped plate.

[0011] Further, support platforms are respectively fixed at the tops of the three groups of arc-shaped connecting pieces forming the lower sleeve body. A centering component is fixed at the top of each support platform. The centering component includes a positioning plate, a screw rod and a base. The base is fixed on the support platform. The screw rod is threadedly connected in the base. The inner end of the screw rod is fixed with a positioning plate. The inner end of the positioning plate contacts the outer wall of the steel column, and the upper part of the positioning plate extends above the steel column.

[0012] Further, the winding device is any one of a winch, a wire winding wheel or a reel.

[0013] Further, a winding assembly is provided on the lower sleeve body. The winding assembly includes a winding seat, a guiding seat, a central shaft, and a driving motor. The winding seat is disposed at the bottom of the lower connecting member. The winding seat is divided into three winding zones by a partition plate. The central shaft is fixedly sleeved inside the winding seat and extends vertically upward. The driving motor is fixed to the top of the lower connecting member, and its output end is in transmission connection with the central shaft. A plurality of guiding seats are fixed to the bottom of the lower sleeve body, and the bottom of each guiding seat is in a C-shaped structure for the connecting rope to pass through correspondingly.

[0014] The present invention also provides a method for automatically correcting steel columns for building construction, including the following steps: Step 1: Correspondingly combine a plurality of arc-shaped connecting members together to form an upper sleeve body, and fixedly sleeve it on the upper steel column so that the arc-shaped plate of the upper sleeve body tightly presses against the outer wall of the upper steel column; Step 2: Correspondingly combine a plurality of arc-shaped connecting members together to form a lower sleeve body, and fixedly sleeve it on the lower steel column so that the arc-shaped plate on the lower sleeve body tightly presses against the outer wall of the lower steel column; Step 3: Use a crane to hoist the upper steel column above the lower steel column, and pass the connecting rope through the guiding seat and fixedly connect it to the connecting ring at the bottom of the positioning rod; Step 4: Drive the winding device to wind the connecting rope, and drive the crane to drive the upper steel column to move downward so that the positioning rod is correspondingly located above the guiding seat; Step 5: Continue to drive the winding device to perform the winding operation. Under the traction of the connecting rope, the positioning rod is adaptively inserted into the guiding seat. At this time, the upper steel column and the lower steel column are coaxial; continue to make the crane drive the upper steel column to move vertically downward until it is butted against the top surface of the lower steel column; Step 6: Perform welding operation on the butt joint surface of the upper steel column and the lower steel column through a welding machine; after welding is completed, the device can be removed.

[0015] The beneficial effects of the above technical solutions are as follows: The device and construction method for automatically correcting steel columns for building construction provided by the present invention transform the traditional steel column correction process that relies on experience into a standardized and automated operation process through the synergistic effects of mechanical restraint, dynamic traction, and geometric guidance, significantly improving construction accuracy, safety, and efficiency.

[0016] Each component of the present invention adopts a split structure, which is convenient for flexibly adjusting the diameter of the sleeve body and the length of the positioning rod according to the size of the steel column, adapting to different engineering requirements, and is convenient for installation and disassembly, significantly improving the reuse rate of the device and the construction adaptability; and the split sleeve body forms a rigid reference through multiple groups of screw clamps, avoiding the slipping problem of traditional temporary jigs and extending the service life of the device.

[0017] In the present invention, the outer diameter of the positioning rod matches the inner diameter of the straight cylinder section of the guiding seat, enabling automatic flexible guiding and rigid limiting in the vertical direction during the hoisting of steel columns, ensuring precise alignment of the central axes of the upper and lower steel columns. The combined use of the connecting rope and the winding device can dynamically adjust the horizontal displacement of the upper steel column during hoisting, achieve fine adjustment and correction through traction balance, avoid the safety hazards of traditional manual high-altitude pushing operations, and improve the adjustment efficiency at the same time.

[0018] In the present invention, the arc structure at the bottom of the positioning rod can come into contact with the curved surface of the inner wall of the conical open end to form a geometric constraint. When there is a slight horizontal offset or inclination of the hoisted upper steel column, the arc end of the positioning rod can slide along the inclined surface of the conical open end. Through the synergistic action of gravity and traction, the positioning rod is automatically guided to move towards the central axis of the guiding seat, realizing passive dynamic deviation correction. This process requires no manual intervention, significantly reduces the requirements for initial hoisting accuracy, and improves the fault tolerance ability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments: Example 1. This example aims to provide an automatic steel column alignment device for building construction, which is mainly used for coaxial docking and alignment construction of the upper and lower steel columns of circular structures to ensure the verticality of the upper and lower steel columns. In the prior art, construction workers assist in pushing the hoisted steel column, and repeatedly confirm the adaptability of the docking surface. This not only has cumbersome operations but also has a low safety factor. In view of the problems of the prior art, this example provides an automatic steel column alignment device for building construction.

[0022] As Figures 1-5 shown, the automatic steel column alignment device for building construction provided in this example includes an arc-shaped connecting piece, an upper sleeve 3, a lower sleeve 4, and a guiding and positioning assembly 5. Among them, both the upper sleeve 3 and the lower sleeve 4 include at least two groups of arc-shaped connecting pieces. At least two groups of arc-shaped connecting pieces are connected end to end correspondingly to form an annular sleeve structure. The arc-shaped connecting piece includes an upper connecting piece 31 and a lower connecting piece 41.

[0023] In a specific implementation structure, as Figure 2 shown, in this example, the upper sleeve 3 is composed of three arc-shaped upper connecting pieces 31. Both ends of the upper connecting piece 31 are integrally formed with ear plates, and screw holes are spaced on the ear plates. In this example, the three upper connecting pieces 31 are correspondingly fixedly connected together by bolts at the head and tail to jointly form an annular upper sleeve 3. In actual application, it can also be jointly composed of two or more than three arc-shaped upper connecting pieces 31 according to production requirements. The bottom of the upper connecting piece 31 is turned outward to form a flange 32, and a screw hole is opened in the middle of the upper connecting piece 31. The upper screw 34 is threadedly connected in this screw hole. The inner end of the upper screw 34 extends to the middle of the upper sleeve 3 and is fixed with an arc-shaped upper clamping plate 35. By screwing the upper screw 34 to drive the upper clamping plate 35 to move inward and outward, and then fixing with a nut, the upper sleeve 3 can be fixedly sleeved on the upper steel column.

[0024] As Figure 3 shown, in this example, the lower sleeve 4 is composed of three arc-shaped lower connecting pieces 41. Both ends of the lower connecting piece 41 are integrally formed with connecting ear plates, and screw holes are spaced on the ear plates. In this example, the three lower connecting pieces 41 are correspondingly fixedly connected together by bolts at the head and tail to jointly form an annular lower sleeve 4. In actual application, it can also be jointly composed of two or more than three arc-shaped lower connecting pieces 41 according to production requirements. A support platform 42 is fixed at the top of the connecting piece. The lower screw 43 is threadedly connected in the middle screw hole of the lower connecting piece 41. The inner end of the lower screw 43 extends to the middle of the lower sleeve 4 and is fixed with an arc-shaped lower clamping plate 44. By screwing the lower screw 43 to drive the lower clamping plate 44 to move inward and outward, and then fixing with a nut, the lower sleeve 4 can be fixedly sleeved on the lower steel column.

[0025] With such a setting in this embodiment, before the upper and lower steel columns 2 are butted, the upper sleeve body 3 and the lower sleeve body 4 can be respectively and fixedly sleeved on the upper and lower steel columns in advance. By screwing the screw rod to drive the clamping plate to press against the surface of the steel column, a rigid positioning reference can be formed on the outer wall of the steel column. Then, the guiding and positioning assembly 5 between the upper and lower sleeve bodies is used to ensure the precise butt joint of the upper steel column 1 and the lower steel column 2 during the hoisting operation.

[0026] Further, as Figure 4 and 5 shown, in this embodiment, the guiding and positioning assembly 5 includes a connecting rope 6, a positioning rod 51, and a guiding seat 52. A positioning seat 33 is fixed on the flanging of the upper sleeve body. The upper screw rod 34 is threadedly connected in the positioning seat 33 and is fixed by screwing a locking nut at the outer end. A positioning rod 51 is fixed at the bottom of the positioning seat 33. The bottom of the positioning rod 51 is a spherical structure, and a connecting ring 54 is fixed at the center of the bottom for tying with the connecting rope 6. A base 53 is fixed on the support platform 42 of the lower sleeve body 4. A through hole 45 is provided in the middle of the base 53, and the through hole 45 penetrates downward to the lower part of the support platform 42. The guiding seat 52 is fixed on the base 53. The inner cavity of the guiding seat 52 is hollow and is coaxial with the through hole on the base 53. And the upper part of the guiding seat 52 is an open structure, and the lower part is a straight cylinder. The outer diameter of the positioning rod 51 is adapted to the inner diameter of the straight cylinder section of the guiding seat 52, so that the positioning rod 51 can be properly sleeved in the straight cylinder structure below the guiding seat 52 to make the positioning rod 51 and the guiding seat 52 coaxial, thereby ensuring that the upper steel column 1 and the lower steel column 2 are concentrically corresponding.

[0027] In addition, as Figure 4 and 5 shown, in this embodiment, the bottom of the positioning rod 51 is an arc structure, and a connecting ring 54 is fixed in the middle of the arc structure. The connecting rope 6 is tied to the connecting ring 54. One end of the connecting rope 6 is connected to the winding device on the ground, and the other end passes upward through the inside of the guiding seat 52 and then the output end is fixedly connected to the connecting ring 54.

[0028] With such a setting of the guiding and positioning assembly 5 of the present invention, through the coaxial adaptation of the positioning rod 51 and the guiding seat 52, combined with the spherical structure at the bottom of the positioning rod 51, it can automatically realize the flexible guiding and rigid limiting in the vertical direction during the hoisting process of the steel column, ensure the accurate alignment of the axes of the upper and lower steel columns, and effectively reduce the deviation risk of manual pushing. And the cooperation of the connecting rope 6 and the winding device can dynamically adjust the horizontal displacement of the upper steel column 1 during the hoisting process, and realize the fine adjustment and correction through the balance of the traction force, avoid the safety hazards of the traditional manual high-altitude pushing operation, and improve the adjustment efficiency at the same time.

[0029] In addition, to prevent interference to the positioning rod 51 caused by the connecting ring 54 when the bottom of the positioning rod 51 moves along the inner wall of the conical open end above the guiding seat 52, which may cause structural damage, in actual application, a groove can be opened at the center of the positioning rod 51 to fix the connecting ring 54 in the groove and then connect it to the connecting rope 6, thereby improving the practicability and structural safety and stability.

[0030] Principle of operation: For the automatic steel column alignment device for building construction provided by the present invention, in actual application, first, according to the diameter of the steel column, select the corresponding number of arc-shaped upper and lower connecting pieces. Connect the ear plates of each arc-shaped connecting piece end to end through bolts, and screw the upper and lower screw rods to press the corresponding clamping plates against the surface of the steel column, forming a complete annular upper sleeve 3 and lower sleeve 4, so as to respectively fix the upper sleeve 3 and lower sleeve 4 on the upper steel column 1 and lower steel column 2, forming a rigid fixing reference. Pass the free end of the connecting rope 6 through the inner cavity of the guiding seat 52 and connect it to a winding device (such as a winch or a manual hoist). Adjust the tension of the connecting rope 6 through the winding device to make the positioning rod 51 in a hanging state.

[0031] Then start the lifting device and slowly lower the upper steel column 1. When the positioning rod 51 approaches the conical open end of the guiding seat 52, use the winding device to adjust the length of the connecting rope 6 so that the arc-shaped end at the bottom of the positioning rod 51 initially enters the open area of the guiding seat 52. The arc-shaped structure of the positioning rod 51 forms a sliding contact with the conical inner wall of the guiding seat 52. During the lifting process, due to the action of gravity, the arc-shaped end automatically slides along the conical surface towards the central axis of the guiding seat 52, realizing passive guiding. When the positioning rod 51 enters the straight cylinder section of the guiding seat 52, continue to lower the upper steel column 1. At this time, the outer diameter of the positioning rod 51 is in close fit with the inner wall of the straight cylinder section, forcibly constraining the axes of the upper steel column 1 and the lower steel column 2 to coincide. When the butt joint surfaces of the upper and lower steel columns are in full contact, stop the lifting, complete the permanent fixation of the upper and lower steel columns 2 by welding, and finally loosen the screw rods of the upper and lower sleeves, release the constraint of the clamping plates on the steel column, disassemble the arc-shaped connecting pieces and remove the sleeves.

[0032] The automatic steel column alignment device for building construction provided by the present invention realizes the automatic alignment of steel column butt joints through a multi-dimensional collaborative mechanism of "mechanical constraint + dynamic traction + geometric guidance". The split sleeve structure of the present invention uses screw clamping to form a rigid positioning reference, solving the pain point of easy slippage of traditional clamps. In the guiding and positioning assembly, the arc-shaped structure at the bottom of the positioning rod 51 and the conical open end of the guiding seat 52 form a funnel, automatically converging the horizontal deviation to the axial direction through sliding contact, and cooperating with the dynamic adjustment of the traction force of the connecting rope 6 to achieve precise centering without manual intervention. This device fundamentally solves the industry problems of low efficiency, high risk, and poor accuracy in steel structure hoisting through high-precision mechanical limits.

[0033] Embodiment 2. On the basis of Embodiment 1, this embodiment further describes the winding arrangement of the connecting rope 6.

[0034] For the winding and relaxation control of the connecting rope 6, in practical applications, devices such as a winch can be selected and placed on the ground. In cooperation with the hoisting and lowering operation of the steel column 1, a rigid wire rope or other tools can be used for the connecting rope. It can also be the structural arrangement of the winding assembly provided in this embodiment, such as Figures 5-7 As shown, this embodiment provides a winding assembly for the connecting rope 6, including a winding seat 7, a guiding seat 8, a central shaft, and a driving motor 9. The winding seat is located below the lower connecting member and does not contact the bottom surface of the lower connecting member. The central shaft is fixedly sleeved inside the winding seat, and the top of the central shaft extends vertically upward. The driving motor 9 is fixed on the top of the lower connecting member 41, and its output end is in transmission connection with the central shaft. In this embodiment, partitions are fixedly sleeved on the winding seat 7 at intervals, so that the winding seat is respectively divided into three winding areas. The connecting ropes 6 wound on each winding area respectively pass through the through holes 45 of the lower connecting member 41, and the output ends are respectively fixedly connected to the connecting rings 54 on the three groups of positioning rods 51.

[0035] Furthermore, to avoid the problem of wire entanglement during the connection winding or relaxation process, in this embodiment, a plurality of guiding seats 8 are respectively fixed at the bottom of the lower connecting member 41. The bottom of each guiding seat 8 is in a C-shaped structure for the connecting rope 6 to pass through, and the heights of the guiding seats 8 corresponding to the three groups of connecting ropes 6 are all different. After the connecting ropes 6 at different positions pass through the guiding seats 8 respectively, they are respectively wound around the three winding areas on the winding seat 7. In this way, when the driving motor 9 is controlled to rotate, the three groups of connecting ropes 6 can be synchronously tightened or relaxed. In addition, when the connecting rope at a position farther from the winding seat passes through the through hole and passes through the bottom of the ear plate, a pulley structure can also be fixed at the bottom of the ear plate to guide it through the pulley. On the one hand, it can guide it to be wound around the winding seat in the correct direction, and on the other hand, it can also prevent the connecting rope from directly contacting the ear plate, thereby causing wear and affecting the service life.

[0036] In this embodiment, the winding assembly is configured such that the central axis of the winding seat is divided into three independent winding areas by a partition. Each group of connecting ropes corresponds to one area, and the central axis is uniformly driven by a drive motor to rotate, ensuring that the three connecting ropes maintain synchronous and equal length movement when winding or unwinding. This prevents uneven force on the upper steel column due to differences in the tightness of individual ropes, thereby maintaining dynamic balance during the correction process and improving centering accuracy. The C-shaped structure and differentiated height design of the guide seat ensure that the three connecting ropes form a spatial layered arrangement after passing through the lower housing, preventing the ropes from rubbing against each other or tangling during the winding and unwinding process. At the same time, the guide seat's guidance and constraints on the connecting ropes further limit their swing range, reduce path deviation caused by wind load or swaying, and ensure the stability of the rope movement trajectory.

[0037] Furthermore, the drive motor, winding seat, and guide seat are directly integrated into the lower casing, eliminating the need for additional ground-based equipment (such as a winch). This reduces the need for auxiliary facilities required for aerial work and is particularly suitable for construction sites with limited space. The modular structure facilitates quick installation and disassembly, and works in conjunction with the casing's rigidity benchmark to enhance the system's overall stability. Furthermore, the three connecting ropes form a triangular traction layout. Even if one cable experiences a sudden malfunction (such as a jam), the remaining two groups can maintain basic correction functionality through force reconfiguration, avoiding the risk of loss of control of the steel column due to single-point failures and significantly improving the system's fault tolerance and construction safety.

[0038] Example 3, based on Examples 1 and 2, this example provides a method for automatically correcting steel columns for construction, specifically comprising the following steps: Step 1: Assemble multiple arc-shaped connectors together to form an upper sleeve, and securely fit it onto the upper steel column so that the arc-shaped plates of the upper sleeve are tightly pressed against the outer wall of the upper steel column; Step 2: Assemble multiple arc-shaped connectors together to form a lower sleeve, and securely fit it onto the lower steel column so that the arc-shaped plates on the lower sleeve are tightly pressed against the outer wall of the lower steel column; Step 3: Use a crane to hoist the upper steel column above the lower steel column, and pass the connecting rope through the guide seat and securely connect it to the connecting ring at the bottom of the positioning rod; Step 4: Drive the winding device to reel the connecting rope, and drive the crane to move the upper steel column downward so that the positioning rod is located above the guide seat; Step 5: Continue to drive the winding device to perform the winding operation. Under the traction of the connecting rope, the positioning rod is adapted to be inserted into the guide seat. At this time, the upper steel column and the lower steel column remain coaxial. Continue to use the crane to drive the upper steel column to move vertically downward until it docks with the top surface of the lower steel column. Step 6: Use a welding machine to weld the butt joints of the upper and lower steel columns; after welding, remove the device.

[0039] The embodiments of the present invention described above do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is that the upper and lower sleeves are first clamped by screws to form a stable reference, and then combined with the coaxial adaptation design of the positioning rod and the guiding seat. At the same time, the cooperation of the connecting rope and the winding device can dynamically adjust the horizontal displacement of the upper steel column during the hoisting process, and achieve fine adjustment and correction through the balance of traction force. Thus, it can automatically realize flexible guidance and rigid limitation in the vertical direction during the hoisting of the steel column, ensuring the precise alignment of the axes of the upper and lower steel columns. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the claims of the present invention.

Step 6: Weld the butting surfaces of the upper steel column and the lower steel column through a welding machine; after welding is completed, the device can be disassembled.
