AI Technical Summary
In construction, the installation of flange connecting columns requires welding of hoisting ear plates, resulting in low construction efficiency and poor economicality.
A lifting device including a chassis, ear plate and reinforcement plate is designed, which matches the top flange hole of the flange connecting column through the bolt hole on the chassis, and is welded to the chassis through the lifting hole on the ear plate to strengthen the plate and ear plate. Weld the plate and the chassis to avoid welding the hoisting ear plates on the columns.
It has achieved simplified production and convenient use, saving construction time and expenses, and improving construction speed and economy.

Abstract
Description
1. Technical Field
[0001] The invention relates to a hoisting device for a flange connection column and belongs to the technical field of building construction. 2. Background Technology
[0002] In the construction of actual engineering structures, the upper and lower sections of some engineering structure columns are connected by high-strength bolt flanges. In order to facilitate the installation of the columns, usually when the columns are made in the factory, the lifting lugs are welded on the columns for installation and construction. After the installation is completed, the lifting lugs are cut off, and the cut parts are repaired by welding, grinding and repainting. This construction method requires a lot of unnecessary labor and materials, affecting the speed and economy of construction. III. Summary of the invention
[0003] The purpose of the present invention is to solve the problem that when installing flange connection columns, hoisting ear plates need to be welded, the construction efficiency is low and the economy is poor, and to provide a hoisting device that avoids welding hoisting ear plates on columns.
[0004] In order to achieve the above object, the present invention adopts the following technical solution:
[0005] A lifting device for flange-connected columns, comprising: a chassis, a lug plate and a reinforcing plate. The characteristics are: a group of bolt holes are opened on the chassis, and the spacing and diameter of the holes are the same as the holes on the top flange of the flange-connected column; a lifting hole is opened on the lug plate, and the lug plate is welded to the chassis; and the reinforcing plate is welded to the lug plate and the chassis.
[0006] The invention has the advantages of simple manufacture, convenient use, avoiding welding of hoisting ear plates on columns, and saving construction time and cost. IV. Description of the drawings
[0007] Figure 1 It is a schematic diagram of the structural composition of the present invention;
[0008] Figure 2 It is a schematic diagram of the application state of the present invention;
[0009] See attached Figure 1 , Attachment Figure 2 The present invention includes a chassis 1, an ear plate 2 and a reinforcing plate 3. V. Specific implementation methods
[0010] For specific embodiments, please refer to the attached Figure 1 A flange connection column hoisting device comprises: a chassis 1, an ear plate 2 and a reinforcing plate 3. The characteristics are: a group of bolt holes 5 are opened on the chassis 1, and the spacing and diameter of the holes are the same as the holes on the top flange 5 of the flange connection column 6; a hoisting hole 4 is opened on the ear plate 2, and the ear plate 2 is welded to the chassis 1; and the reinforcing plate 3 is welded to the ear plate 2 and the chassis 1.
[0011] When applying, refer to the attached Figure 2 , connect the chassis 1 of the hoisting device and the top flange 5 of the flange connection column 6 with bolts 8 and tighten them, and then the hoisting operation can be carried out.
