Description

Technical Field

[0001] The invention belongs to the technical field of auxiliary construction, in particular to an auxiliary construction device for a steel tube concrete column. Background Art

[0002] At present, steel tube concrete columns are used as load-bearing components in construction projects. Since steel tubes can work together with concrete, the working conditions of steel tubes and concrete under pressure can be improved. For steel tubes, since the tubes are filled with concrete, the stability of the tube wall under pressure is improved to a certain extent. For core concrete, during the compression process, due to the constraint of the steel tube wall, it is in a state of triaxial stress, which greatly improves the strength of the concrete.

[0003] However, when pouring concrete into the steel pipe after the construction is completed, since the steel pipe is in a straight state, the construction workers need to take the pouring pipe to pour concrete at the pouring area of ​​the steel pipe, and the height of the steel pipe is relatively high, and the construction workers cannot safely and effectively align it for pouring, resulting in low construction efficiency, and when opening and closing the pouring, the excess concrete accumulated at the pouring port is easy to stick to the outer wall of the steel pipe, resulting in the overall aesthetics of the steel pipe after the pouring is low, and the concrete attached to the outer wall of the steel pipe will affect the performance of the steel pipe.

[0004] By setting up a conveying mechanism to transport concrete and enabling it to freely adjust the pouring height and position, it is possible to adapt to the pouring of steel pipes of more sizes. By cleaning the pouring port, it is prevented that excess concrete falls on the outer wall of the steel pipe during opening and closing pouring, thereby reducing the overall aesthetics of the steel pipe. Summary of the invention

When excess concrete adheres to the edge of the steel pipe, and when the height needs to be changed to cast steel pipes of different heights, the first servo motor 602 is started, and the first servo motor 602 drives the take-up roller 603 to rotate, so that the take-up roller 603 reels or loosens the wire 604, thereby raising and lowering the height of the lifting frame 5, so that the device can adapt to steel pipes of different heights and grout them. Furthermore, when grouting steel pipes installed in an array at the same height, the second servo motor 607 can be started to drive the screw 608 to rotate, so that the screw 608 drives the connecting block 609 to move when rotating due to its own shape, and then drives the grouting position of the grouting head 802 clamped and fixed by the clamping arm 610 to move in parallel, so that the grouting of multiple groups of steel pipes arranged in an array at the same height can be met without moving the device, thereby improving the efficiency of the device in grouting multiple groups of steel pipes.
