Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a device for concrete pouring of steel columns. Background Technology

[0002] Concrete-steel columns are composite structures in which concrete is filled into steel tubes. This structure combines the characteristics of concrete and steel, and can give full play to their respective advantages when subjected to stress. Steel provides good ductility, and concrete provides compressive resistance, giving it the characteristics of high load-bearing capacity, good ductility, and excellent seismic performance. It is widely used in the construction of steel structures, bridges and other fields.

[0003] Concrete pouring for steel columns typically employs either pumping and jacking or direct pouring. Pumping and jacking requires sophisticated equipment and is more expensive. Direct pouring is more commonly used on-site. For tall column structures, this usually involves creating sections of opening at suitable locations on the sidewall, erecting scaffolding, and using chutes for segmented concrete pouring. However, scaffolding erection, changing pouring locations (pouring site changes), and closing openings are time-consuming and labor-intensive, hindering project cost control and pouring quality control. Furthermore, it requires significant manual labor, has low mechanization, and does not align with current construction trends. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for concrete pouring of steel columns that is simple in structure, effectively reduces labor input, and saves construction time.

[0005] This utility model is achieved through the following technical solution: a device for concrete pouring of steel columns, including a hopper, a winch, and an electromagnetic chuck. The winch is installed at the top of the steel column and connected to the hopper. The winch is used to drive the hopper to rise and fall along the height direction of the steel column. The electromagnetic chuck is installed on the side wall of the hopper and is used to make the hopper adhere to the outer surface of the steel column. The outlet of the hopper is connected to a discharge pipe. The steel column has multiple feed inlets spaced apart along its height direction.

[0006] Furthermore, a vibrator is provided on the hopper, and the vibrator is located near the outlet of the hopper.

[0007] Furthermore, plate-type lifting lugs are respectively provided on the left and right side walls of the hopper, and the hoisting rope of the winch is connected to the plate-type lifting lugs.

[0008] Furthermore, it also includes two traction ropes, which are respectively connected to the plate-type lifting lugs on the left and right side walls of the hopper.

[0009] Furthermore: a support frame is provided on the top side wall of the steel column, and the support frame and the feed inlet are on the same side, and the winch is fixed on the support frame.

[0010] Furthermore, the inner wall of the hopper is provided with three spaced strip-shaped mounting boxes, and each strip-shaped mounting box is provided with the electromagnetic chuck.

[0011] Furthermore, it also includes a circumferentially closed steel member, which is used to seal the inlet that has been filled.

[0012] Furthermore, each of the strip-shaped mounting boxes is equipped with an electromagnetic sensor.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model uses a winch to control the hopper to move up and down on the surface of a steel column, and adjusts the hopper with a traction rope. An electromagnetic chuck stabilizes the hopper on the steel column surface, aligning it with the column's feed inlet. This allows for concrete pouring of the steel column with minimal manual labor, effectively reducing personnel input and ensuring construction safety. It also reduces time spent on scaffolding erection and manual relocation of the work surface, significantly saving construction time. Compared to other processes, it can use ordinary self-compacting concrete, effectively saving material costs. Mechanized segmented pouring allows for fast and smooth segment transitions, facilitating control of concrete pouring quality, avoiding construction joints, and features a simple structure that can be assembled using existing on-site equipment, effectively reducing work difficulty.

[0015] 2. By installing a vibrator near the hopper outlet, the vibrating action of the vibrator can ensure that the hopper discharges material evenly and avoids overflow.

[0016] 3. The feed inlet is sealed with a circumferentially enclosed steel structure, which can effectively ensure that the connection of individual steel columns is carried out in sections. Attached Figure Description

Detailed Implementation

[0024] Figures 1 to 6 The present invention provides a schematic diagram of an embodiment of a device for concrete pouring of steel columns, including a hopper 1, a winch 2, and an electromagnetic chuck 3. The winch 2 is located on the top of the steel column 4 and is connected to the hopper 1. The winch 2 is used to drive the hopper 1 to move up and down along the height direction of the steel column 4. The electromagnetic chuck 3 is located on the side wall of the hopper 1 and is used to make the hopper 1 adhere to the outer surface of the steel column 4. The discharge port of the hopper 1 is connected to a discharge pipe 6. The steel column 4 has multiple feed ports 5 that are spaced apart along its height direction.

[0025] A vibrator 7 is installed on the hopper 1, and the vibrator 7 is located near the outlet of the hopper 1.

[0026] The vibrator 7 is a small vibrator 7.

[0027] Plate-type lifting lugs 8 are respectively provided on the left and right side walls of the hopper 1, and the lifting rope 9 of the winch 2 is connected to the plate-type lifting lugs 8.

[0028] It also includes two traction ropes 10, which are respectively connected to the plate-type lifting lugs 8 on the left and right side walls of the hopper 1.

[0029] A support frame 11 is provided on the top side wall of the steel column 4, and the support frame 11 and the feed inlet 5 are on the same side. The winch 2 is fixed on the support frame 11.

[0030] The inner wall of the hopper 1 is provided with three spaced strip-shaped mounting boxes 12, and each strip-shaped mounting box 12 is provided with an electromagnetic chuck 3.

[0031] It also includes a circumferentially enclosed steel member 13, which is used to seal the already filled feed inlet 5.

[0032] The two ends of the circumferential closed steel member 13 are connected by bolts 14.

[0033] Each strip-shaped mounting box 12 is equipped with an electromagnetic sensor.

[0034] In use, before pouring concrete, the electromagnetic chuck 3 and electromagnetic sensor are installed in the strip-shaped mounting box 12. The hoisting rope 9 of the winch 2 is connected to the plate-type lifting lug 8 on the side wall of the hopper 1. The winch 2 drives the hopper 1 to descend above the bottom feed inlet 5. The traction rope 10 is used to adjust the direction of the hopper 1 so that the discharge pipe 6 of the hopper 1 extends into the feed inlet 5 of the steel column 4. The electromagnetic chuck 3 is activated so that the hopper 1 is attracted to the outer surface of the steel column 4 to stabilize the hopper 1. At the same time, the traction rope 10 and the winch 2 are tightened appropriately. When the concrete 15 is poured, the concrete 15 is... 5. The concrete 15 is slowly poured into the hopper 1. The concrete 15 is poured into the steel column 4 through the discharge pipe 6 of the hopper 1 from the inlet 5. During the pouring of the concrete 15, the change in the pouring height of the concrete 15 will affect the reflection or absorption characteristics of electromagnetic waves. The electromagnetic sensor judges the pouring height of the concrete 15 by sensing the change in the magnetic field. When the pouring surface of the concrete 15 is slightly lower than the inlet 5, the pouring stops. The hoist 2 lifts the hopper 1 to the next inlet 5. At the same time, the circumferential closed steel component 13 is used to close the already poured inlet 5. This cycle is repeated until the top inlet 5 is poured.

[0035] After the top feed inlet 5 is poured, concrete 15 is injected from the top of the steel column 4 until it is full and sealed with a column cap. After the pouring is completed, the reversing sealing component is welded to the steel column 4 in a circumferential full-section manner.

[0036] The above detailed description is a specific description of a feasible embodiment of the present utility model. This embodiment is not intended to limit the patent scope of the present utility model. All equivalent implementations or modifications that do not depart from the present utility model should be included in the patent scope of this case.
