Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, and in particular to a multi-functional adjustment component for steel column installation. Background Technology

[0002] In steel structure factory building projects, steel column installation is a crucial step in the main structure construction. The traditional method involves measuring the elevation of the foundation slab, hoisting the steel column into the foundation, and temporarily fixing it with triangular wedges around the column to ensure it is roughly aligned with the axis. Controlling the column's installation elevation typically requires a second hoisting, inserting steel shims at the bottom of the column for elevation adjustments, and repeated checks until the design requirements are met.

[0003] The aforementioned traditional methods have the following main drawbacks: First, elevation adjustment requires repeated lifting of the steel column and insertion of shims, which is cumbersome, inefficient, and the fixed thickness of the shims makes continuous stepless adjustment impossible, making it difficult to guarantee elevation accuracy. Second, adjusting the axis position requires setting up external jacking equipment such as jacks along the foundation, which limits the operating space, makes tool setup difficult, and requires the pre-fabrication of fine-tuning auxiliary parts, making the process complex. Third, repeated lifting and hammering adjustments can easily damage the concrete surface of the foundation, affecting the foundation quality. Fourth, the entire installation process takes up a lot of crane time and requires a large amount of manpower, which is particularly disadvantageous when the construction period is tight.

[0004] Therefore, there is an urgent need for a steel column installation and adjustment tool system that is simple to operate, quick to adjust, reusable, and causes minimal damage to the foundation. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a multi-functional adjustment component for steel column installation, so as to solve the problems of repeated lifting and low accuracy required for steel column installation elevation adjustment in the prior art, as well as limited operating space and complex tools for axis adjustment.

[0006] The present invention provides a multi-functional adjustment assembly for steel column installation, including an elevation adjustment device and an axis adjustment device;

[0007] The elevation adjustment device is installed inside the cup-shaped foundation and is used to support the steel column. It includes an inclined adjustment plate, an adjustment base and a drive mechanism. The inclined adjustment plate can be driven by the drive mechanism to move relative to the adjustment base in a direction inclined to the horizontal plane, thereby generating vertical displacement and driving the steel column to rise and fall vertically.

[0008] The axis adjustment device is disposed between the side wall of the steel column and the side wall of the cup-shaped foundation, and is used to drive the steel column to move horizontally relative to the side wall of the cup-shaped foundation.

[0009] Furthermore, the lower surface of the inclined adjustment disc is provided with a first inclined surface, and the upper surface of the adjustment base is provided with a second inclined surface that slides in cooperation with the first inclined surface; the driving mechanism includes an adjusting bolt arranged in the horizontal direction, the adjusting bolt is connected between the inclined adjustment disc and the adjustment base, and is configured to drive the inclined adjustment disc to slide along the second inclined surface when rotated, thereby driving the steel column to rise and fall vertically.

[0010] Furthermore, the adjusting bolt is rotatably inserted into a through hole on the adjusting base, the through hole being a vertically extending oblong hole, so that the adjusting bolt can move vertically up and down with the inclined adjusting disc; the adjusting bolt is threadedly engaged with the inclined adjusting disc, so that when the adjusting bolt is rotated, the inclined adjusting disc is driven to slide along the second inclined surface and drive the steel column to move vertically up and down.

[0011] Furthermore, the upper surface of the inclined adjustment plate is a support end face for supporting the steel column. The support end face is provided with a detachable fixing structure. The detachable fixing structure is used to fix the inclined adjustment plate to the bottom of the steel column before hoisting, so that the elevation adjustment device is hoisted into the cup-shaped foundation along with the steel column as a whole.

[0012] Furthermore, the axis adjustment device includes a support chassis, a support end plate, and a drive assembly;

[0013] The supporting base and the supporting end plate are respectively disposed at both ends of the driving assembly. The supporting base is configured to be installed on the side wall of the steel column, and the supporting end plate is configured to abut against the side wall of the cup-shaped foundation.

[0014] The drive assembly is used to drive the support end plate to extend outward or retract inward relative to the support base, thereby generating or releasing a horizontal thrust between the steel column sidewall and the cup-shaped foundation sidewall.

[0015] The outer end face of the support plate is used to abut against the inner surface of the cup-mouth base sidewall, and the cup-mouth base sidewall is used as a reaction fulcrum to push the steel column to move horizontally.

[0016] Furthermore, the drive assembly includes an operating lever and a transmission mechanism that transmits the rotation of the operating lever as the extension and retraction of the support end plate. The operating lever can selectively drive the support end plate to extend or retract.

[0017] Furthermore, the transmission mechanism includes a rotating component, a connecting screw, and a reversing assembly. The rotating component is mounted on one of the supporting chassis and the supporting end plate in a rotatable and axially limited manner. One end of the connecting screw is fixedly connected to the other of the supporting chassis and the supporting end plate. The rotating component is threadedly engaged with the connecting screw. The reversing assembly engages with the operating lever, causing the operating lever to drive the rotating component to rotate in a first rotational direction when rotating in a first direction to extend the supporting end plate, and to drive the rotating component to rotate in the opposite second rotational direction when rotating in the opposite second direction to retract the supporting end plate.

[0018] Furthermore, the reversing assembly includes a forward helical gear and a reverse helical gear coaxially fixed to the rotating member. The operating lever has a conical rotating head that meshes with the forward and reverse helical gears. Both the forward and reverse helical gears have an arc-shaped ratchet structure with a gradually changing radius along the circumference. The conical rotating head has a toothed portion that meshes with the arc-shaped ratchet structure. The operating lever is configured to move along the axial direction of the rotating member so that the conical rotating head selectively meshes with the forward or reverse helical gear.

[0019] When the operating lever is moved to the first position and rotated in the first direction, the conical rotating head meshes with the forward drive gear, driving the rotating component to rotate in the first rotation direction;

[0020] When the operating lever is moved to the second position and rotated in the opposite second direction, the conical rotating head meshes with the reverse drive gear, driving the rotating component to rotate in the second rotation direction;

[0021] This drives the rotating component to rotate in the corresponding direction, and through the threaded engagement between the rotating component and the connecting screw, it causes the support end plate to extend or retract.

[0022] Furthermore, the axis adjustment device also includes a connecting assembly, which is installed on the support chassis for sliding the axis adjustment device along the side wall of the steel column and can lock the axis adjustment device after it reaches a predetermined position.

[0023] Furthermore, the connecting assembly includes a limiting end plate and a pair of adjustable-spacing claws; the claws are used to slidably engage the support chassis with the side wall of the steel column, and the limiting end plate is provided with a locking bolt. The spacing between the pair of claws is adjusted and locked by the locking bolt, so that the claws clamp the side wall of the steel column, thereby locking the axis adjustment device at a predetermined position on the steel column.

[0024] The beneficial effects of this invention are as follows: The multi-functional adjustment component for steel column installation of this invention forms a complete steel column installation adjustment system by setting up an elevation adjustment device and an axis adjustment device. The elevation adjustment device adopts an inclined plane fit structure, converting the horizontal rotational motion of the bolts into the vertical lifting motion of the inclined adjustment disc, realizing continuous stepless adjustment of the steel column installation elevation. This eliminates the need for secondary lifting of the steel column and inserting shims; operators can complete the fine-tuning of the elevation from outside the foundation, making operation simple, quick, and highly accurate. The axis adjustment device is installed on the side wall of the steel column via a support base. An operating lever drives the transmission mechanism to open the support end plate and abut against the side wall of the foundation. Using the side wall of the foundation as a reaction fulcrum, the steel column is moved horizontally, achieving effective adjustment of the steel column axis position in narrow spaces without the need for external jacks along the foundation. The entire component has a simple structure, is easy to install and disassemble, has high operating efficiency, and is reusable, significantly saving labor and material costs and reducing damage to the foundation concrete during construction. It is particularly suitable for steel structure factory construction scenarios with tight schedules. Meanwhile, after the adjustment is completed, both the elevation adjustment device and the axis adjustment device can be left as permanent supports in the cup-shaped foundation, forming an integral whole with the grouting concrete, which further enhances the stability of the steel column installation.

Figure 3 This is an exploded view of the elevation adjustment device of the present invention. Figure 4 This is a schematic diagram showing the installation of the axis adjustment device of the present invention at the groove. Figure 5 This is a schematic diagram of the installation of the axis adjustment device of the present invention on the side wall. Figure 6 The figure shows a partial cross-sectional view of the axis adjustment device of the present invention. This embodiment provides a multi-functional adjustment component for steel column installation. This component is mainly used to precisely adjust the installation elevation and axis position of the steel column 1 when installing it in the cup-shaped foundation 2. The multi-functional adjustment component for steel column installation in this embodiment includes an elevation adjustment device 3 and an axis adjustment device 4. These are independent, separate devices that work together to complete the installation and adjustment of the steel column 1 in actual use. The elevation adjustment device 3 is responsible for fine-tuning the vertical height of the steel column 1, while the axis adjustment device 4 is responsible for fine-tuning the horizontal displacement of the steel column 1. Working together, they form an efficient construction procedure of "adjusting the elevation first, then adjusting the axis."

[0034] In this embodiment, the elevation adjustment device 3 is installed inside the cup-shaped foundation 2 and is used to support the steel column 1. It includes an inclined adjustment plate 31, an adjustment base 32, and a drive mechanism. The inclined adjustment plate 31 is located at the bottom of the steel column 1, and its upper surface directly supports the entire weight of the steel column 1. The adjustment base 32 is located below the inclined adjustment plate 31, and its lower surface supports the bottom surface of the cup-shaped foundation 2. The inclined adjustment plate 31 can be driven by the drive mechanism to move relative to the adjustment base 32 in a direction inclined to the horizontal plane, thereby generating vertical displacement and driving the steel column 1 to rise and fall vertically. This design converts the horizontal driving force into a vertical lifting force, allowing operators to work on the outer side of the cup-shaped foundation 2 without having to work in the narrow space at the bottom of the steel column 1, greatly facilitating construction.

[0035] In this embodiment, the lower surface of the inclined adjustment disc 31 is provided with a first inclined surface, and the upper surface of the adjustment base 32 is provided with a second inclined surface that slides in cooperation with the first inclined surface. Both the first and second inclined surfaces are planar inclined surfaces, and they fit together to form a sliding pair. The driving mechanism includes an adjusting bolt 34 arranged horizontally. The adjusting bolt 34 is connected between the inclined adjustment disc 31 and the adjustment base 32, and is configured to drive the inclined adjustment disc 31 to slide along the second inclined surface when rotated, thereby causing the steel column 1 to rise and fall vertically. When the adjusting bolt 34 rotates, the inclined adjustment disc 31 slides horizontally along the second inclined surface. Due to the wedge effect of the inclined surface, the horizontal sliding is converted into a vertical rising and falling motion, realizing the elevation adjustment of the steel column 1. Furthermore, this inclined surface mechanism has a self-locking characteristic, and once adjusted to the correct position, it can maintain a stable elevation without additional locking measures.

[0036] In this embodiment, the adjusting bolt 34 is rotatably inserted into a through hole in the adjusting base 32. The through hole is a vertically extending oblong hole 37, allowing the adjusting bolt 34 to move vertically up and down with the inclined adjusting disc 31. The oblong hole 37 design allows the adjusting bolt 34 to move vertically along with the inclined adjusting disc 31 when it slides along the inclined surface, avoiding jamming caused by rigid constraints. The adjusting bolt 34 is threadedly engaged with the inclined adjusting disc 31. Specifically, the inclined adjusting disc 31 has a threaded structure that engages with the adjusting bolt 34, or is provided with a nut that engages with the adjusting bolt 34, so that when the adjusting bolt 34 is rotated, the inclined adjusting disc 31 is driven to slide along the second inclined surface and drive the steel column 1 to move vertically up and down. The operator can conveniently tighten the adjusting bolt 34 from the outside of the cup-shaped base 2 using a wrench 33 or the like, achieving remote and precise operation.

[0037] In this embodiment, the upper surface of the inclined adjustment plate 31 serves as a support end face for supporting the steel column 1, and the support end face is provided with a detachable fixing structure. The detachable fixing structure includes a fixing wing plate 35 disposed on the upper part of the inclined adjustment plate 31, and fastening bolts 36 are provided on the fixing wing plate 35. The detachable fixing structure is used to fix the inclined adjustment plate 31 to the bottom of the steel column 1 before hoisting. Specifically, the upper surface of the inclined adjustment plate 31 is supported on the bottom end face of the steel column 1, and then the inclined adjustment plate 31 is fixed to the bottom of the steel column 1 by the fastening bolts 36, so that the elevation adjustment device 3 is hoisted into the cup-shaped foundation 2 along with the steel column 1. This pre-fixing method eliminates the cumbersome steps of post-installation inside the cup-shaped foundation 2, improves construction efficiency, and also ensures the stability and safety of the elevation adjustment device 3 during hoisting.

[0038] In this embodiment, the axis adjustment device 4 is disposed between the side wall of the steel column 1 and the side wall of the cup-shaped foundation 2, and is used to drive the steel column 1 to move horizontally relative to the side wall of the cup-shaped foundation 2. The axis adjustment device 4 includes a support base 42, a support end plate 43, and a drive assembly. The support base 42 and the support end plate 43 are respectively disposed at both ends of the drive assembly, and are spaced apart from each other. The support base 42 is configured to be mounted on the side wall of the steel column 1, serving as the fixed end of the axis adjustment device 4; the support end plate 43 is configured to abut against the side wall of the cup-shaped foundation 2, serving as the movable end of the axis adjustment device 4. The drive assembly is used to drive the support end plate 43 to extend outward or retract inward relative to the support base 42, thereby generating or releasing a horizontal thrust between the side wall of the steel column 1 and the side wall of the cup-shaped foundation 2. The outer end face of the support plate 43 is used to abut against the inner surface of the side wall of the cup-mouth base 2, and the side wall of the cup-mouth base 2 is used as the reaction fulcrum to push the steel column 1 to move horizontally, so as to achieve precise positioning of the axial position of the steel column 1.

[0039] In this embodiment, the driving assembly includes an operating lever 41 and a transmission mechanism that transmits the rotation of the operating lever 41 to the extension and retraction of the support end plate 43. The operating lever 41 can selectively drive the support end plate 43 to extend or retract. The operating lever 41 allows the operator to operate from above or to the side of the cup base 2, overcoming the problem of narrow internal space and inconvenience for tool operation in the cup base 2.

[0040] In this embodiment, the transmission mechanism includes a rotating component 48, a connecting screw 49, and a reversing assembly. The rotating component 48 is mounted on one of the supporting base 42 and the supporting end plate 43 in a rotatable and axially limited manner. One end of the connecting screw 49 is fixedly connected to the other of the supporting base 42 and the supporting end plate 43. In this embodiment, the rotating component 48 is rotatably and axially limitedly mounted on the supporting end plate 43, and one end of the connecting screw 49 is fixedly connected to the supporting base 42. The rotating component 48 and the connecting screw 49 are threadedly engaged. When the rotating component 48 rotates, the threaded engagement drives the connecting screw 49 to move axially, thereby causing the supporting end plate 43 to extend or retract relative to the supporting base 42. The reversing assembly cooperates with the operating lever 41, causing the operating lever 41 to drive the rotating member 48 to rotate in the first rotation direction when rotating in the first direction, thereby extending the support end plate 43; and to drive the rotating member 48 to rotate in the opposite second rotation direction when rotating in the opposite second direction, thereby retracting the support end plate 43. The design of the reversing assembly allows the operator to flexibly control the bidirectional movement of the support end plate 43 simply by changing the rotation direction or position of the operating lever 41, making operation intuitive and simple.

[0041] In this embodiment, the reversing assembly includes a forward helical gear 44 and a reverse helical gear 45 coaxially fixed to the rotating member 48. The forward helical gear 44 and the reverse helical gear 45 are arranged in a mirror-symmetrical manner and are responsible for torque transmission in different rotational directions, respectively. The operating lever 41 has two conical rotating heads at its mating end that mesh with the forward helical gear 44 and the reverse helical gear 45, respectively. Both the forward helical gear 44 and the reverse helical gear 45 have an arc-shaped ratchet structure with a gradually changing radius along the circumference, and the conical rotating head has a toothed portion that meshes with the arc-shaped ratchet structure. The large and small head design of the arc-shaped ratchet structure makes the meshing between the gear and the conical rotating head directionally selective: in one rotational direction, the toothed portion meshes tightly with the arc-shaped ratchet to transmit torque; in the opposite rotational direction, the toothed portion slips along the inclined surface of the arc-shaped ratchet and cannot transmit torque, thus achieving a "slippage" effect. The operating lever 41 is configured to move along the axial direction of the rotating member 48, allowing the conical rotating head to selectively engage with either the forward helical gear 44 or the reverse helical gear 45. When the operating lever 41 moves to a first position and rotates in a first direction, one conical rotating head engages with the forward helical gear 44, driving the rotating member 48 to rotate in the first rotation direction. When the operating lever 41 moves to a second position and rotates in the opposite second direction, the other conical rotating head engages with the reverse helical gear 45, driving the rotating member 48 to rotate in the second rotation direction. Through this reversing mechanism, the rotation of the operating lever 41 in different directions is converted into the rotation of the rotating member 48 in the corresponding direction. The threaded engagement between the rotating member 48 and the connecting screw 49 causes the support end plate 43 to extend or retract, achieving precise bidirectional adjustment of the axial position of the steel column 1.

[0042] In this embodiment, the axis adjustment device 4 further includes a connecting assembly. The connecting assembly is mounted on the support chassis 42 and is used to slide the axis adjustment device 4 along the side wall of the steel column 1. It can also lock the axis adjustment device 4 after it reaches a predetermined position. As shown in the figure, the connecting assembly includes two forms, which can be installed on the side wall of the steel column 1 or in a groove, respectively, to meet the axis adjustment needs of the steel column 1 in different directions. The connecting assembly allows the axis adjustment device 4 to be easily adjusted in height on the side wall of the steel column 1 to adapt to adjustment requirements at different positions.

[0043] In this embodiment, the connecting assembly includes a limiting end plate 47 and a pair of adjustable-gap claws 46. The claws 46 are used to slidably engage the support base 42 with the side wall or groove of the steel column 1, and are equipped with a telescopic spring. The telescopic spring provides preload to keep the claws 46 in contact with the side wall of the steel column 1. The limiting end plate 47 is provided with locking bolts and bolt holes. The spacing between the pair of claws 46 is adjusted and locked by the locking bolts, so that the claws 46 clamp the side wall of the steel column 1, thereby locking the axis adjustment device 4 in a predetermined position on the steel column 1. The limiting end plate 47 also maintains a consistent installation height of the axis adjustment device 4 on the side wall of the steel column 1, preventing tilting or slippage of the device during operation and ensuring effective transmission of horizontal thrust. This is prior art and will not be described further here.

[0044] This application also discloses a rapid installation and adjustment method for a steel column 1. This method utilizes the aforementioned multi-functional adjustment assembly for steel column installation during construction, and specifically includes the following steps:

[0045] S1. Install the elevation adjustment device 3 at the bottom of the steel column 1. Specifically, before hoisting the steel column 1, support the upper surface of the inclined adjustment plate 31 on the ground against the bottom end face of the steel column 1, and fix the inclined adjustment plate 31 to the bottom side wall of the steel column 1 by the fastening bolts 36 on the fixed wing plate 35, thus completing the pre-fixing of the elevation adjustment device 3. The elevation adjustment device 3 can support the steel column 1 and adjust its vertical height. After installation, the elevation adjustment device 3 and the steel column 1 form an integral unit, which facilitates subsequent hoisting operations.

[0046] S2. The steel column 1 equipped with the elevation adjustment device 3 is hoisted into the cup-shaped foundation 2. A crane is used to lift the steel column 1 as a whole, so that the adjustment base 32 rests on the bottom surface of the cup-shaped foundation 2, thus completing the initial positioning of the steel column 1.

[0047] S3. Adjust the installation elevation of the steel column 1 using the elevation adjustment device 3. The operator uses a wrench 33 to rotate the adjusting bolt 34 outside the cup-shaped foundation 2. The adjusting bolt 34 drives the inclined adjusting plate 31 to slide along the second inclined surface of the adjusting base 32. By utilizing the inclined surface, the horizontal displacement is converted into vertical displacement, which drives the steel column 1 to rise and fall vertically, and precisely adjusts the installation elevation of the steel column 1 to the design requirements.

[0048] S4. The axis adjustment device 4 is positioned between the side wall of the steel column 1 and the side wall of the cup-shaped foundation 2. Specifically, the claws 46 of the axis adjustment device 4 are engaged with the side wall of the steel column 1. The spacing of the claws 46 is adjusted by a telescopic spring, allowing the axis adjustment device 4 to slide along the side wall of the steel column 1. The axis adjustment device 4 is then pushed downwards into the gap between the side wall of the steel column 1 and the side wall of the cup-shaped foundation 2. After reaching the predetermined position, the spacing of the claws 46 is locked by the locking bolts on the limiting end plate 47. The axis adjustment device 4 can generate a horizontal thrust between the side wall of the steel column 1 and the side wall of the cup-shaped foundation 2.

[0049] S5. The steel column 1 is moved horizontally by the axis adjustment device 4 to adjust its axial position. The operator uses the operating lever 41 to select the driving direction via the reversing assembly, driving the rotating component 48 to rotate. Through the threaded engagement of the rotating component 48 and the connecting screw 49, the support end plate 43 extends outward and abuts against the inner surface of the side wall of the cup-mouth base 2. Using the side wall of the cup-mouth base 2 as a reaction fulcrum, the steel column 1 is moved horizontally, achieving precise positioning of the axial position. If reverse adjustment is required, the meshing gear can be switched by moving the operating lever 41.

[0050] S6. After completing the installation elevation and axis position adjustment, both the elevation adjustment device 3 and the axis adjustment device 4 are placed inside the cup-shaped foundation 2, and the gaps inside the cup-shaped foundation 2 are filled with concrete grout. After grouting, the elevation adjustment device 3 and the axis adjustment device 4 form an integral whole with the concrete as permanent support components, further enhancing the installation stability and long-term reliability of the steel column 1.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
