Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a prefabricated column lifting tool. Background Art

[0002] In the traditional hoisting operation of prefabricated columns, the hoisting tools usually hoist directly through the reserved holes of the prefabricated columns. This method has certain safety hazards. On the one hand, if the position of the reserved holes of the prefabricated columns is inaccurate, it will affect the hoisting balance of the prefabricated columns, which may cause the prefabricated columns to tilt or flip during the hoisting process, causing safety accidents. On the other hand, the reserved holes of the prefabricated columns may be worn by the hoisting tools, resulting in a decrease in the structural strength of the prefabricated columns. To this end, the inventors proposed a prefabricated column hoisting tool. Utility Model Content

[0030] Example 1

[0031] See also Figure 1-Figure 2 In this embodiment, the prefabricated column lifting tool includes a support tube 10 inserted into the reserved hole 51 on the prefabricated column 50 oppositely, the outer end of the support tube 10 is provided with a baffle 11 abutting against the outer wall of the prefabricated column 50, the baffle 11 is connected to the lifting ring 30 through the sling 20, and the inner end of the support tube 10 is formed with a clamping plate 12 and a clamping groove 13 distributed along the circumferential direction. The clamping plates 12 and the clamping grooves 13 of the two corresponding support tubes 10 are correspondingly plugged in, and the clamping plate 12 is screwed and connected with the screw 40 inserted into the support tube 10.

[0032] In this embodiment, the two plug-in supporting tubes 10 are connected as a whole by a screw 40, and the baffle 11 is abutted against the outer wall of the prefabricated column 50, so that the center position of the line connecting the two hanging points can be located on the axis of the prefabricated column 50, thereby ensuring the stability of the hoisting and having the advantage of easy operation.

[0033] It should be noted that the support tube 10 is constructed as a whole into a cylindrical shape with an internal thread. As an example, the outer diameter of the support tube 10 is equal to the diameter of the reserved hole 51. The disc-shaped baffle 11 is welded to the outer end of the support tube 10, and the baffle 11 and the support tube 10 are coaxially arranged. A lifting ear 14 is welded on the outer wall of the baffle 11, and the lifting ear 14 is connected to the lifting ring 30 by a sling 20.

[0034] In addition, the support tube 10 is cut axially to form a slot 13 and a clamping plate 12. A rectangular notch is cut axially on the tube wall of the support tube 10. The notch is the slot 13. The tube wall between adjacent slots 13 forms a clamping plate 12. The inner wall of the clamping plate 12 retains the thread on the inner wall of the support tube 10. For example, the slot 13 and the clamping plate 12 have the same curvature.

[0035] It should be understood that the clamping plate 12 and the clamping groove 13 formed by cutting make the clamping plate 12 and the support tube 10 located on the same circumferential surface. When the clamping plates 12 on the two opposing support tubes 10 are inserted into the corresponding clamping grooves 13, the upper clamping plates 12 of the two corresponding support tubes 10 can enclose a cylindrical portion with the same configuration as the support tube 10. The inner wall of the cylindrical portion forms a complete thread and maintains a threaded connection with the screw 40 screwed into the support tube 10.

[0036] It should be noted that the reserved hole 51 is a through hole formed on the prefabricated column 50, and the reserved hole 51 is arranged along the diameter direction of the prefabricated column 50. The screw 40 is threadedly connected to the two support tubes 10 at the same time. At the same time, the screw 40 is also threadedly connected to the clamping plates 12 of the two support tubes 10. The screw 40 is used to connect the two support tubes 10 as one. The baffle 22 on the support tube 10 is abutted against the outer wall of the prefabricated column 10, and the two lifting ears 14 are symmetrically arranged on both sides of the prefabricated column 10, so that the midpoint of the line connecting the two lifting points formed by the two slings 20 on the two lifting ears 14 can be located at the axis of the prefabricated column 50, thereby improving the stability of the lifting.

[0037] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
