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. Traditional steel column installation methods typically involve 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 roughly align it with the axis. Controlling the column's installation elevation often requires lifting the column two or more times, inserting steel shims at the bottom of the column for elevation adjustments, and repeatedly checking until the design requirements are met. Adjusting the axis position usually requires setting up external jacks or other jacking equipment along the foundation slab, which limits operating space and makes tool setup difficult.

[0003] The aforementioned traditional construction methods have the following main drawbacks: First, elevation adjustment requires repeated lifting of the steel column, which is cumbersome, takes up a lot of crane time, and has low construction efficiency; Second, the thickness of the pad is fixed, making continuous stepless adjustment impossible and elevation accuracy difficult to guarantee; Third, axis adjustment requires the installation of external equipment along the cup-shaped foundation, which is complex and extremely inconvenient to operate in a narrow space; Fourth, repeated lifting and hammering adjustments can easily damage the concrete surface of the cup-shaped foundation, affecting the foundation quality; Fifth, the entire installation process requires a large amount of labor, has a long construction period, and high construction costs.

[0004] Therefore, there is an urgent need for a method for the rapid installation and adjustment of steel columns 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 rapid installation and adjustment method for steel columns, so as to solve the problems of repeated lifting, low elevation adjustment accuracy, inconvenient axis adjustment operation and low construction efficiency in the prior art.

[0006] The present invention provides a method for rapid installation and adjustment of a steel column, comprising the following steps:

[0007] S1. Install the elevation adjustment device at the bottom of the steel column. The elevation adjustment device can support the steel column and adjust its vertical height.

[0008] S2. Hoist the steel column equipped with the elevation adjustment device into the cup-shaped foundation;

[0009] S3. Adjust the installation elevation of the steel column using the elevation adjustment device;

[0010] S4. The axis adjustment device is set between the side wall of the steel column and the side wall of the cup-shaped foundation. The axis adjustment device can generate a horizontal thrust between the side wall of the steel column and the side wall of the cup-shaped foundation.

[0011] S5. The steel column is moved horizontally by the axis adjustment device to adjust the axis position of the steel column;

[0012] S6. After completing the installation elevation and axis position adjustment, the gap in the cup-shaped foundation is filled with concrete grout.

[0013] Furthermore, the elevation adjustment device includes an inclined adjustment disc, an adjustment base, and a drive mechanism. 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 drive mechanism drives the inclined adjustment disc to slide along the second inclined surface, so that the inclined adjustment disc generates a vertical displacement relative to the adjustment base, thereby adjusting the installation elevation of the steel column.

[0014] Furthermore, the driving mechanism includes an adjusting bolt arranged in the horizontal direction. The adjusting bolt is rotatably inserted into a waist-shaped hole on the adjusting base. The adjusting bolt is threadedly engaged with the inclined adjusting disc. By rotating the adjusting bolt, the inclined adjusting disc is driven to slide along the second inclined surface, converting the horizontal displacement into a vertical displacement.

[0015] Furthermore, the elevation adjustment device also includes a detachable fixing structure disposed on the upper part of the inclined adjustment plate. The detachable fixing structure includes a fixing wing plate disposed on the upper part of the inclined adjustment plate and a fastening bolt disposed on the fixing wing plate. The fastening bolt is used to fix the inclined adjustment plate to the bottom of the steel column before hoisting, and to make the upper surface of the inclined adjustment plate support the bottom end face of the steel column.

[0016] Furthermore, the axis adjustment device includes a support base, a support end plate, and a drive assembly; the support base is installed on the side wall of the steel column, and the support end plate is disposed near the side wall of the cup-shaped foundation; by driving the drive assembly, the support end plate extends outward relative to the support base and abuts against the side wall of the cup-shaped foundation, using the side wall of the cup-shaped foundation as a reaction fulcrum to push the steel column to move horizontally.

[0017] Furthermore, the drive assembly includes an operating lever, a rotating component, a connecting screw, and a reversing assembly; the rotating component is mounted on one of the support chassis and the support end plate in a rotatable and axially limited manner, one end of the connecting screw is fixedly connected to the other, and the rotating component is threadedly engaged with the connecting screw; the rotating component engages with the operating lever, such that when the operating lever rotates in a first direction, it drives the rotating component to rotate in a first rotational direction to extend the support end plate, and when it rotates in the opposite second direction, it drives the rotating component to rotate in the opposite second rotational direction to retract the support end plate.

[0018] Furthermore, the reversing assembly includes a forward helical gear and a reverse helical gear coaxially fixed to both ends of the rotating member. The operating lever has two conical rotating heads that mesh with the forward and reverse helical gears respectively. 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, a conical rotating head meshes with the positive 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, another 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 component, which is installed on the support chassis. The axis adjustment device is slidably engaged with the side wall of the steel column through the connecting component and pushed into the gap between the side wall of the steel column and the side wall of the cup-shaped foundation. After the axis adjustment device reaches the predetermined position, the axis adjustment device is locked and installed on the steel column.

[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] Furthermore, both the elevation adjustment device and the axis adjustment device are steel components, which are left in the cup-shaped foundation as permanent supports after grouting.

[0025] The beneficial effects of this invention are as follows: By pre-installing the elevation adjustment device at the bottom of the steel column before hoisting and hoisting it into the foundation in one go with the steel column, this invention eliminates the tedious process of lifting the steel column twice and repeatedly inserting shims in traditional methods, significantly reducing crane occupancy time and improving construction efficiency. The elevation adjustment uses a sloping surface mechanism to convert the horizontal rotational motion of the bolts into vertical lifting motion, achieving continuous stepless adjustment of the steel column elevation with high precision. Operators can complete the operation from outside the foundation, making it convenient and quick. The axis adjustment involves sliding the axis adjustment device along the side wall of the steel column into the gap, using a built-in transmission mechanism to open the support plate, and using the side wall of the foundation as a reaction fulcrum to push the steel column horizontally. This eliminates the need for external jacks along the foundation, solving the operational difficulties of axis adjustment in narrow spaces. After adjustment, both the elevation adjustment device and the axis adjustment device remain within the foundation as permanent supports, forming an integral whole with the grouted concrete, further enhancing the stability of the steel column installation. The entire method is simple, easy to operate, and quick to adjust. It can be repeatedly applied to the installation of multiple steel columns, greatly saving labor and construction costs. It is especially suitable for steel structure factory construction scenarios with tight schedules. Attached Figure Description

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 discloses a rapid installation and adjustment method for steel columns. The method utilizes an elevation adjustment device 3 and an axis adjustment device 4 for construction, and specifically includes the following steps:

[0035] S1. Install the elevation adjustment device 3 at the bottom of the steel column 1. The elevation adjustment device 3 can support the steel column 1 and adjust its vertical height.

[0036] In this step, the elevation adjustment device 3 includes an inclined adjustment disc 31, an adjustment base 32, and a drive mechanism. The lower surface of the inclined adjustment disc 31 has a first inclined surface, and the upper surface of the adjustment base 32 has a second inclined surface that slides in conjunction 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 drive mechanism includes an adjusting bolt 34 arranged horizontally. The adjusting bolt 34 is rotatably inserted into a slotted hole 37 on the adjustment base 32. The slotted hole 37 is a vertically extending elongated hole, allowing the adjusting bolt 34 to move vertically together with the inclined adjustment disc 31. The adjusting bolt 34 is threadedly engaged with the inclined adjustment disc 31.

[0037] In practice, before hoisting the steel column 1, the upper surface of the inclined adjustment plate 31 is supported on the bottom end face of the steel column 1 on the ground. The inclined adjustment plate 31 is then fixed to the bottom of the steel column 1 using a detachable fixing structure located on its upper part. The detachable fixing structure includes a fixing wing plate 35 on the upper part of the inclined adjustment plate 31 and fastening bolts 36 on the fixing wing plate 35. By tightening the fastening bolts 36, the inclined adjustment plate 31 is clamped and fixed to the bottom of the steel column 1, completing the pre-fixing of the elevation adjustment device 3. After installation, the elevation adjustment device 3 and the steel column 1 form a whole, facilitating subsequent hoisting operations.

[0038] S2. The steel column 1, which is equipped with the elevation adjustment device 3, is hoisted into the cup-shaped foundation 2.

[0039] Using a crane, the steel column 1, pre-fixed with the elevation adjustment device 3, is lifted as a whole and vertically lowered into the cup-shaped foundation 2, so that the lower surface of 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. Since the elevation adjustment device 3 has been installed before hoisting, this step only requires one hoisting to place the steel column 1 in place, without the need for a second hoisting.

[0040] S3. Adjust the installation elevation of the steel column 1 using the elevation adjustment device 3.

[0041] The operator uses a wrench 33 to rotate the adjusting bolt 34 outside the cup-shaped foundation 2. The adjusting bolt 34 is threaded onto the inclined adjusting plate 31. Rotating the adjusting bolt 34 drives the inclined adjusting plate 31 to slide along the second inclined surface of the adjusting base 32. Due to the interaction between the first and second inclined surfaces, the horizontal sliding of the inclined adjusting plate 31 is converted into a vertical lifting motion, causing the inclined adjusting plate 31 to have a vertical displacement relative to the adjusting base 32, thereby driving the steel column 1 to rise and fall vertically. By rotating the adjusting bolt 34, the horizontal displacement is converted into a vertical displacement, precisely adjusting the installation elevation of the steel column 1 to the design requirements. The adjusting bolt 34 moves vertically together with the inclined adjusting plate 31 within the slotted hole 37, ensuring a smooth and unobstructed adjustment process. This inclined surface mechanism has a self-locking characteristic, and once adjusted to the correct position, it maintains a stable elevation without the need for additional locking measures.

[0042] S4. The axis adjustment device 4 is set between the side wall of the steel column 1 and the side wall of the cup-shaped foundation 2. 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.

[0043] In this step, the axis adjustment device 4 includes a support chassis 42, a support end plate 43, and a drive assembly. The axis adjustment device 4 also includes a connecting assembly, which is mounted on the support chassis 42. The connecting assembly includes a limiting end plate 47 and a pair of adjustable-gap claws 46, and is equipped with a telescopic spring.

[0044] In specific operation, the jaws 46 of the axis adjustment device 4 are engaged with the side wall or groove of the steel column 1. The spacing of the jaws 46 is adjusted by the telescopic spring, so that the axis adjustment device 4 is slidably engaged with the steel column 1. Then, the axis adjustment device 4 is pushed down along the side wall of the steel column 1 into the gap between the side wall of the steel column 1 and the side wall of the cup-shaped foundation 2. After the axis adjustment device 4 reaches the predetermined position, the spacing between the pair of jaws 46 is adjusted and locked by the locking bolts provided on the limiting end plate 47, so that the jaws 46 clamp the side wall of the steel column 1, locking the axis adjustment device 4 in the predetermined position of the steel column 1. The setting of the limiting end plate 47 can also keep the installation height of the axis adjustment device 4 on the side wall of the steel column 1 consistent, prevent the device from tilting or slipping during operation, and ensure the effective transmission of horizontal thrust.

[0045] S5. The steel column 1 is moved horizontally by the axis adjustment device 4 to adjust the axis position of the steel column 1.

[0046] In this step, the drive assembly includes an operating lever 41, a rotating component 48, a connecting screw 49, and a reversing assembly. The rotating component 48 is mounted on one of the supporting chassis 42 and the supporting end plate 43 in a rotatable and axially limited manner, and one end of the connecting screw 49 is fixedly connected to the other. In this embodiment, the rotating component 48 is rotatably and axially limited on the supporting end plate 43, and one end of the connecting screw 49 is fixedly connected to the supporting chassis 42, with the rotating component 48 and the connecting screw 49 threadedly engaged. The reversing assembly includes a forward helical gear 44 and a reverse helical gear 45 coaxially fixed to both ends of the rotating component 48, and the forward helical gear 44 and the reverse helical gear 45 are arranged in a mirror-symmetrical manner. 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 is provided with toothed portions that mesh with the arc-shaped ratchet structure. The operating lever 41 is configured to move along the axial direction of the rotating member 48 so that the conical rotating head selectively meshes with either the forward helical gear 44 or the reverse helical gear 45.

[0047] In specific operation, the operator moves the operating lever 41 to the first position and rotates the operating lever 41 in the first direction, causing a conical rotating head to mesh with the positive helical gear 44. The conical rotating head drives the positive helical gear 44 to drive the rotating component 48 to rotate in the first rotation direction. Through the threaded engagement between the rotating component 48 and the connecting screw 49, the connecting screw 49 causes the support end plate 43 to extend outward relative to the support base 42. The outer end face of the support end plate 43 gradually abuts against the inner surface of the side wall of the cup-mouth foundation 2. Using the side wall of the cup-mouth foundation 2 as the reaction fulcrum, continuing to rotate the operating lever 41 will push the steel column 1 to move horizontally in the opposite direction, achieving fine adjustment of the axial position. When reverse adjustment is required, move the operating lever 41 to the second position and rotate the operating lever 41 in the opposite second direction so that the other conical rotating head meshes with the reverse helical gear 45, driving the rotating part 48 to rotate in the second rotation direction. Through the threaded engagement, the support end plate 43 retracts inward relative to the support base plate 42, releasing the horizontal thrust. Then the axis adjustment device 4 can be repositioned or removed.

[0048] The large and small head design of the arc-shaped ratchet structure allows for directional selectivity in the meshing between the gear and the conical rotating head: in one direction of rotation, the toothed portion meshes tightly with the arc-shaped ratchet to transmit torque; in the opposite direction of rotation, the toothed portion slips off along the inclined surface of the arc-shaped ratchet, failing to transmit torque. This design allows the operator to flexibly control the bidirectional movement of the support end plate 43 simply by changing the rotation direction or axial position of the operating lever 41, making operation intuitive and simple.

[0049] S6. After completing the installation elevation and axis position adjustment, the gap in the cup-shaped foundation 2 is filled with concrete grout.

[0050] After the installation elevation and axis position of steel column 1 are adjusted to the design requirements, 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. Both the elevation adjustment device 3 and the axis adjustment device 4 are steel components, which, after grouting, serve as permanent supports and form an integral whole with the concrete, further enhancing the installation stability and long-term reliability of steel column 1.

[0051] The operational sequence of steps S3, S4, and S5 is as follows: first, the installation elevation of steel column 1 is adjusted, and then the axial position of steel column 1 is adjusted. This "adjust elevation first, then adjust axial position" process design ensures that the bottom of steel column 1 is subjected to uniform force during elevation adjustment, and that the elevation is already stable during axial position adjustment, so the two do not interfere with each other, thus improving the overall adjustment accuracy and construction efficiency.

[0052] 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.
