Description

Technical Field

[0001] This utility model relates to the field of steel column hoisting technology, and more specifically, to a steel column hoisting lug device that can be repeatedly installed and dismantled. Background Technology

[0002] In steel structure construction, steel columns are typically hoisted using welded lifting lugs. These lugs, as construction materials, serve only for hoisting and have no other practical use. During production, the high consumption of lug material and the large amount of welding work increase production costs. Furthermore, after hoisting, if the lugs interfere with subsequent construction processes (such as floor slab laying), they must be manually removed, wasting both materials and labor. Moreover, removing lugs requires hot work, posing safety hazards and potentially causing secondary damage to the structure itself. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a reusable steel column lifting lug device that eliminates the need to weld lifting lugs onto each steel column using traditional methods. This device is safe and reliable to use and will not have a negative impact on the structure.

[0004] The present invention adopts the following technical solution:

[0005] A reusable steel column lifting lug device includes a steel plate, a lifting lug installed at the middle of the upper end of the steel plate, two bolt mounting holes on the steel plate, a washer plate installed at the lower end of the steel column, bolts passing through the bolt mounting holes, the steel column and the washer plate, and a nut installed at the bottom of the bolt, the number of washer plates being equal to the number of bolts.

[0006] Furthermore, two symmetrical steel column lifting lug devices are installed on each steel column. The steel column includes a steel column upper plate, a steel column lower plate, and a steel column middle plate. The steel column middle plate connects the steel column upper plate and the steel column lower plate. Two sets of lifting lug device mounting holes are installed on the steel column upper plate. The lifting lug device mounting holes are arranged in a straight line. The pad is located at the lower end of the steel column upper plate, and the steel plate is located at the upper end of the steel column upper plate. Bolts pass through the lifting lug device mounting holes.

[0007] Furthermore, two pads are symmetrically arranged on both sides of the steel column's middle plate.

[0008] Furthermore, the lifting lug includes a rectangular plate and a semi-circular plate. The lower end of the rectangular plate is fixed to a steel plate, and the semi-circular plate is provided with lifting holes.

[0009] Furthermore, multiple reinforcing plates are installed at the connection between the lifting lug and the steel plate.

[0010] Furthermore, the stiffening plate is connected to the lifting lugs and the steel plate by welding, and the lifting lugs are connected to the steel plate by welding.

[0011] Beneficial effects

[0012] This invention is flexible in use, can be made with on-site materials and is reusable. It eliminates the need to weld lifting lugs to each steel column using traditional methods, thereby reducing material waste and production costs. It is also safe and reliable in use and will not have a negative impact on the structure. Attached Figure Description

[0015] Figure 3 This is a schematic diagram illustrating another perspective of an embodiment of the present utility model. Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] As shown in the figure, this utility model discloses a reusable steel column lifting lug device, including a steel plate 1, a lifting lug 2 installed at the middle of the upper end of the steel plate 1, two bolt mounting holes 101 on the steel plate 1, a pad 4 installed at the lower end of the steel column 3, a bolt 5 passing through the bolt mounting holes 101, the steel column 3 and the pad 4, a nut installed at the bottom of the bolt 5, and the number of pads 4 is equal to the number of bolts 5.

[0018] This invention eliminates the need to weld lifting lugs onto the steel column 3 to be hoisted. Instead, the lifting lugs are pre-welded to the steel plate 1. During installation, the steel plate 1 is directly connected to the steel column 3. This reduces material waste, welding workload, labor, and production costs. Furthermore, it is safe and reliable during use, requires no hot work, and will not negatively impact the structure. After use, the entire steel column lifting lug device is disassembled from the steel column 3 and reused for hoisting the next steel column.

[0019] In one embodiment of this utility model, two symmetrical steel column lifting lug devices are installed on each steel column 3. The steel column 3 includes a steel column upper plate 31, a steel column lower plate 32, and a steel column middle plate 33. The steel column middle plate 33 connects the steel column upper plate 31 and the steel column lower plate 32. Two sets of lifting lug device mounting holes 331 are installed on the steel column upper plate 31. The lifting lug device mounting holes 331 are arranged in a straight line. The pad 4 is located at the lower end of the steel column upper plate 31, and the steel plate 1 is located at the upper end of the steel column upper plate 31. The bolt 5 passes through the lifting lug device mounting holes 331.

[0020] This utility model is installed on the upper plate 31 of a steel column. A steel plate 1 is placed on the upper plate 31 of the steel column, and bolts 5 are used to fix the steel plate 1 and the upper plate 31 of the steel column, ensuring a stable installation. Then, lifting lugs are installed to indirectly lift the steel column 3.

[0021] The pad 4 serves to protect the lower end of the upper plate 31 of the steel column.

[0022] In one embodiment of this utility model, two pads 4 are symmetrically arranged on both sides of the steel column middle plate 33.

[0023] The two pads 4 are designed to distribute stress symmetrically and avoid applying pressure to one side of the upper plate 31 of the steel column.

[0024] In one embodiment of the present invention, the lifting lug 2 includes a rectangular plate 22 and a semi-circular plate 21. The lower end of the rectangular plate 22 is fixed on the steel plate 1, and the semi-circular plate 21 is provided with a lifting hole 211.

[0025] The hook lifts the lifting lug 2 from the lifting hole 211 of the lifting lug 2, and indirectly lifts the steel column 3.

[0026] In one embodiment of this utility model, multiple reinforcing plates 6 are installed at the connection between the lifting lug 2 and the steel plate 1. The reinforcing plates 6 serve to strengthen the lifting lug and distribute the pulling force of the hook on the lifting lug 2.

[0027] In one embodiment of this utility model, the stiffening plate 6 is connected to the lifting lug 2 and the steel plate 1 by welding, and the lifting lug 2 is connected to the steel plate 1 by welding.

[0028] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
