[0052] In one embodiment, see Figure 3 and Figure 4In the process of pouring concrete for prefabricated frame columns using existing technology, a sky pump 9 is used to pour from the top of the column. Due to the dense steel bars in the column cap, the pump pipe cannot be extended to the bottom of the column, making it impossible to ensure that the free fall height of the concrete does not exceed 3 meters, resulting in stratification and segregation and poor quality of concrete molding for tall independent columns. A steel column mold integral structure 7 is used, which is provided with a movable device 8 for pouring holes on the side of the steel column mold. A movable device 8 for pouring holes on the side of the steel column mold is provided at 2.5m, 5.0m and 7.5m respectively. First, all the cover plates 1 are pulled out of the slots 2, and the pump pipe of the sky pump 9 is extended into the pouring hole 6 at 2.5m on the side of the steel column mold integral structure 7 for pouring. When the pouring surface rises to 2.0m, the pouring is stopped, the pump pipe of the sky pump 9 is withdrawn, the cover plate 1 is inserted into the slot 2, and the 2.5m is closed. The pouring hole 6 at the top is then inserted into the pump pipe of the sky pump 9 at 5.0m for pouring. When the pouring surface rises to 2.5m, the pouring is stopped and the pump pipe of the sky pump 9 is withdrawn. The cover plate 1 is inserted into the slot 2, the pouring hole 6 at 5.0m is closed, and the pump pipe of the sky pump 9 is inserted into the pouring hole 6 at 7.5m for pouring. When the pouring surface rises to 7.0m, the pump pipe of the sky pump 9 is withdrawn, the cover plate 1 is inserted into the slot 2, the pouring hole 6 at 7.0m is closed, and pouring is then carried out from the top of the column. This ensures that the free fall height of the concrete is less than 3m, avoids stratification and segregation, and improves the concrete molding quality of tall independent columns.

[0053] This utility model achieves segmented casting of tall, independent columns using steel molds by providing casting holes on the side of the steel mold and controlling their opening and closing via a cover plate and a slot. This utility model can be used to retrofit existing steel column molds, demonstrating its versatility. It boasts a simple structure and is easy to operate and use. It effectively prevents delamination and segregation, improving the quality of concrete formed for tall, independent columns.
