Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for concrete column processing, specifically a concrete column hole forming component and a concrete column forming module that is simple in structure, has good forming effect, high forming efficiency, and high load-bearing capacity. Background Technology

[0002] As is well known, a concrete column is the part of a concrete pile that extends above the ground. A common construction method for concrete columns is to use a molding mold to pour concrete into it. This molding mold typically includes a cylindrical steel plate, a cover plate, and a column hole forming component. The cover plate has a grouting hole in its center, and positioning holes for the forming component are distributed around its circumference. During construction, the cylindrical steel plate is first placed on the concrete pile, and then the cover plate is fixed to the upper end of the cylindrical steel plate. Next, the column hole forming component is vertically fixed through the positioning holes. At this point, a grouting cavity is formed between the cylindrical steel plate, the cover plate, and the column hole forming component. Concrete slurry is then filled into the grouting cavity of the molding mold through the grouting holes. After molding and fixing, the column hole forming component is... Pull out the cover plate, remove the cylindrical steel plate, and in this process, because the column hole forming part is a smooth rod-shaped structure, the inner end face of the column hole on the formed column is a smooth hole. During the connection between the column and the upper foundation, because the column hole is a smooth hole, there is insufficient connection strength in the connection of the steel bars with the foundation. However, since it is formed by concrete grouting, it would be complicated to process it into a rough hole later and affect the overall strength and performance of the concrete. However, it is difficult to process the column hole into a rough hole during the concrete forming process. Therefore, it is necessary to develop a structure that can form a rough column hole and remove the column hole forming part after the concrete is formed. Summary of the Invention

[0021] A method for forming a concrete column, characterized by the following steps:

[0022] (1) Making concrete column hole forming part 9: The column hole forming part 9 includes an air bag 1, a support frame, an air inlet pipe 3, and an air extraction pipe 4. The support frame includes an upper support 2, a lower support 5, and a connecting frame 6. The upper support 2 and the lower support 5 are circular. The circular upper support 2 and the lower support 5 are connected and fixed by the connecting frame 6.

The upper support 2, the lower support 5, and the connecting frame 6 are covered with an air bag 1. The air bag 1 is wrapped around the cylindrical structure formed by the upper support 2, the lower support 5, and the connecting frame 6. The air bag 1 is fixedly connected to the upper support 2 and the lower support 5. The upper end of the air bag 1 is connected to the air inlet pipe 3 and the air extraction pipe 4 respectively. After the air bag 1 is inflated, the middle part expands and protrudes out of the connecting frame 6. After the air bag 1 is deflated, it shrinks into the connecting frame 6.

[0023] (2) Assemble the concrete column forming module: The forming module includes a cylindrical steel plate 7, a cover plate 8 and a column hole forming component 9 in step (1). The cover plate 8 has a grouting hole 10 in the middle. The grouting hole 10 has positioning holes for the forming component distributed in the circumferential direction.

[0026] (5) Demolding: After the concrete column in step (4) is formed, the airbag 1 is evacuated by the air pump. After evacuation, the airbag 1 shrinks and detaches from the concrete slurry until it shrinks onto the connecting frame 6. Then the column forming part is pulled out. After pulling out, the cover plate 8 and the cylindrical steel plate 7 are removed in sequence to finally complete the concrete column with the column hole with a rough surface.
