1. In the construction of the bottom of the circular column formwork to level, which is the bottom of the formwork construction must be carried out before the leveling work, if the bottom is not leveled or leveling deviations, will lead to the verticality of the circular column formwork is not enough, pouring the column tilt, and even the possibility of tipping. So in the bottom leveling to use the leveling instrument, so that the leveling error into the possible small, in order to ensure the verticality of the column.
2. Circular column formwork reinforcement when fastening steel belt specifications and spacing must be mastered, especially the staggered installation of the circular column formwork, can not only focus on the installation spacing of the steel belt, but also pay attention to the joints in the template, the upper and lower layers are to tighten the fastening steel belt, fastening. This is to reduce the spacing of the fastening steel belt, in fact, the reinforcement of the circular column formwork more solid. Therefore, the fastening steel belt can not only look at the spacing, but also pay attention to the seams of the template.
3. For large diameter circular column formwork, after supporting the formwork, must be used around the circular column formwork for the second reinforcement of the square column, the location of the square wood, placed immediately adjacent to the spacing of the template, as well as the spacing has been to uniform. This secondary reinforcement of the square wood is to protect the verticality of the circular column formwork, but also to increase the load-bearing capacity of the circular column formwork.
4. Circular wood formwork at the groove, must be affixed with transparent tape, so that you can place the construction circular wood formwork groove into the ash. The purpose of doing so is to protect the most vulnerable part of the circular column formwork.
