Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a steel column hoisting device and a construction method thereof. Background Art

[0002] During construction, the traditional method for installing rigid circular steel columns involves using four shackles mounted on a single column's lifting lug. The installation team then performs the installation and alignment, and the welding team then performs the welding. This method requires workers to climb up and down each column to remove the shackles, and the entire process, from installation to welding, takes nearly two hours. Workers must perform alignment after measuring and positioning, without releasing the lifting machinery. This lengthy and time-consuming process increases labor costs, and the frequent climbing up and down of the columns impacts the densely packed rebar within the structure, posing a significant safety hazard.

[0032] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] Reference Figures 1 to 5 As shown, the present invention provides a steel column lifting device, including: a plurality of limit members 1, a movable kit 2, and a position adjustment component 3.

[0035] The plurality of position limiting members 1 are fixedly mounted on the upper ends of the plurality of steel columns 4. In some embodiments, the position limiting members are plate-shaped, welded to the outer sides of the steel columns, and arranged along the radial direction of the steel columns.

[0036] As a preferred embodiment, a limiting member 1 is fixedly provided on opposite sides of the upper end of the steel column 4. A pair of limiting members is symmetrically fixedly provided on the upper end of each steel column.

[0037] The movable kit 2 includes two first plywoods 21 and lifting ears 22. Specifically, the two first plywoods are detachably stacked together. A plurality of first limiting grooves are formed on opposite sides of the two first plywoods 21. The first limiting grooves pass through the first plywood. A plurality of first limiting grooves are arranged along the length direction of the first plywood 21. The two first limiting grooves of the two first plywoods 21 that are positioned opposite to each other form a first set of holes. The first set of holes is used for the upper end of the steel column 4 to be movably passed through. The first plywood 21 is supported by a plurality of limiting members 1. Lifting ears 22 are respectively connected to the opposite ends of the two first plywoods 21.

[0038] In this embodiment, the first clamping plate is a rectangular steel plate. The center of the rectangular steel plate is bent to form a plurality of first retaining grooves. When the two first clamping plates are aligned, the first set of holes formed by the corresponding first retaining grooves in the two first clamping plates has a diameter greater than the outer diameter of the steel column and smaller than the sum of the steel column diameter and the length of the retaining member. Therefore, the two first clamping plates, when aligned, are supported by the retaining member.

[0039] The positioning assembly 3 includes two second splints 31 and a positioning member 32. The two second splints 31 are detachably stacked together. A plurality of second limiting grooves are formed on opposite sides of the two second splints 31. The plurality of second limiting grooves are arranged along the length direction of the second splints 31. The second limiting grooves of the two second splints 31 are enclosed to form a second set of holes. The second set of holes is used for the lower end of the steel column 4 to pass through movably. The aperture of the second set of holes is larger than the outer diameter of the steel column. A gap is set between the inner wall of the second sleeve and the side of the steel column. The second splint 31 is provided with a plurality of through holes. The through holes are connected to the second set of holes. A plurality of through holes are arranged along the circumferential direction of the second set of holes. The positioning member 32 is installed in the through hole in an adjustable manner. The positioning member 32 extends into the second set of holes and the positioning member 32 abuts against the lower end of the steel column 4.

[0040] In this embodiment, the second clamping plate is a rectangular steel plate. The center of the rectangular steel plate is bent to form a plurality of second limiting grooves. When the two second clamping plates are aligned, the second set of holes formed by the corresponding second limiting grooves in the two second clamping plates has a diameter greater than the outer diameter of the steel column.

[0041] In a preferred embodiment, the positioning member 32 is formed with external threads. The through-hole is formed with internal threads. The positioning member 32 is threadedly engaged with the through-hole. The depth of the positioning member extending into the second set of holes is adjusted by rotating the positioning member. When adjusting the position of the steel column in the second set of holes, the multiple positioning members cooperate to adjust the lower end of the steel column to be coaxial with the installed steel column below.

[0042] As a preferred embodiment, each second sleeve is provided with at least four positioning members 32 in the circumferential direction. The at least four positioning members 32 are arranged at equal intervals.

[0043] In this embodiment, see Figure 3 As shown, four positioning members 32 are spaced circumferentially around each of the second set of holes. Each positioning member has an inner end and an outer end. The inner end of the positioning member extends into the second set of holes and presses against the outer side of the steel column, while the outer end of the positioning member extends outside the second clamping plate. A stop flange is formed on the outer end of the positioning member. Construction personnel use this stop flange to quickly and easily adjust the depth of the positioning member's extension into the second set of holes.

[0044] See Figure 2 As shown, two first splints 21 are stacked together by a tension assembly. Specifically, the tension assembly includes a tension rod 23 and a pressing member 24.

[0045] The first clamping plate 21 is provided with a plurality of first locking holes. These first locking holes are arranged along the length of the first clamping plate. The middle portion of the tie rod 23 is movably inserted into the first locking holes of the two first clamping plates 21. Removably connected to the opposing ends of the tie rod 23 are pressing members 24. The pressing members 24 press against the opposite sides of the first clamping plates 21.

[0046] In this embodiment, both ends of the tie rod 23 are formed with external threads. The pressing member 24 is provided with a threaded hole. The pressing member 24 is screwed to the end of the tie rod 23.

[0047] Continue reading Figure 3 The second splint is also stacked together by a tension assembly. The specific structure of the tension assembly is the same as that of the first splint, so it will not be repeated here.

[0048] The present invention provides a construction method of a steel column hoisting device, comprising the following steps:

[0049] S1: Fix a plurality of position limiting members 1 to the upper ends of a plurality of steel columns 4 respectively.

[0050] S2: The two first splints 21 of the movable kit 2 are detachably stacked together, so that the first set of holes formed by the two first limiting grooves positioned opposite to each other of the two first splints 21 can be movably mounted on the upper end of the steel column 4, and the first splint 21 is supported on multiple limiting members 1.

[0051] Among them, when the movable kit is installed on the upper ends of multiple steel columns at the same time, the two first splints are detachably stacked together through the pulling assembly, so that the first limiting grooves of the two first splints form multiple first sets of holes, and then the multiple first sets of holes are movably mounted on the upper ends of multiple steel columns.

[0052] S3: The two second clamping plates 31 of the positioning assembly 3 are detachably stacked together, so that the second set of holes formed by the second limiting grooves of the two second clamping plates 31 can be movably sleeved on the lower end of the steel column 4, and the positioning member 32 of the positioning assembly 3 is pressed against the lower end of the steel column 4.

[0053] Among them, when the positioning assembly is installed on the upper ends of multiple steel columns at the same time, the two second splints are detachably stacked together through the pulling assembly, so that the second limiting grooves of the two second splints form multiple second sets of holes, and then the multiple second sets of holes are movably mounted on the lower ends of multiple steel columns.

[0054] The positioning assembly can be locked to the lower ends of multiple steel columns through positioning pieces.

[0055] Preferably, to facilitate subsequent adjustment of the steel column's position within the second set of holes, a support member is welded to the lower end of the steel column. The support member is supported by the second clamping plate. With the support member, when hoisting multiple steel columns, there is no need to lock the adjustment assembly to the lower ends of the multiple steel columns using a locating member. Consequently, subsequent adjustments to the steel column's position can be made directly using the locating member, thereby shortening the steel column installation process.

[0056] S4: hoisting the lifting ears 22 at opposite ends of the two first clamping plates 21 of the movable kit 2 by a hoisting machine, so that the plurality of steel columns 4 are arranged above the upper ends of the installed steel columns 4 .

[0057] Specifically, the lifting rope of the lifting machinery is connected to the lifting ears at both ends of the first clamping plate.

[0058] The movable kit is lifted upward by a lifting machine, so that multiple steel columns are connected with the positioning components and lifted together to the installation position of the steel columns.

[0059] S5: Temporarily fix the second clamping plate 31 of the adjustment assembly 3, and adjust the positions of the plurality of positioning members 32 in the through-holes of the second clamping plate 31 so that the steel column 4 is coaxially arranged with the installed steel column 4.

[0060] Specifically, in a set of positioning members positioned opposite to each other in the second set of holes, when the depth of one positioning member extending into the second set of holes increases, the other positioning member correspondingly retreats to the same depth in the through-hole, so that the steel column is clamped in the opposite set of positioning members.

[0061] In this way, the position of the steel column in the second set of holes can be adjusted quickly and accurately through multiple sets of positioning parts in multiple directions.

[0062] S6: Weld the lower end of the steel column 4 to the upper end of the installed steel column 4.

[0063] S7: Lower the movable kit through the lifting machinery so that the movable kit slides down along the steel column to the lower end of the steel column.

[0064] Specifically, the lifting rope is lowered by the lifting machinery, so that the movable kit slides down along the steel column to the lower end of the steel column, and then the construction workers can remove the movable kit and adjustment components at the lower end of the steel column, avoiding frequent high-altitude operations for the construction workers and reducing safety hazards during the installation of the steel column.

[0065] S8: Remove the movable kit and adjustment components.

[0066] Specifically, the movable kit and the positioning assembly are separated from the plurality of steel columns by disassembling the tensioning assembly.

[0067] The steel column hoisting device of the present invention can simultaneously hoist multiple steel columns and quickly position them in the same cycle, which has outstanding advantages when facing tight construction schedules and insufficient manpower. On the other hand, the steel column accurately adjusts its position under the coordinated cooperation of multiple positioning parts of the positioning assembly, and the column bottom is fully welded and connected. The steel column is accurately installed, and finally the lifting rope is lowered by the lifting machinery to adjust the movable kit to the bottom of the hoisted steel column. The construction workers can disassemble the movable kit together with the positioning assembly at the lower end of the steel column, that is, the construction workers can complete the rapid disassembly while standing on the floor. This is an innovation that fundamentally changes the previous need for workers to climb up to the top of the column by climbing a ladder and hanging a safety belt to disassemble.

[0068] The steel column lifting device of the present invention has extremely high precision to ensure the quality of the main structure. Specifically, the positioning piece is threaded, and the horizontal error within 1 mm can be achieved by controlling the number of turns of the positioning piece in four directions.

[0069] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention herein is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features having similar functions disclosed in this application.
