Useful Construction Tips for Concrete Column Formwork
To retain the concrete shuttering tightly in proper position and for correct arrangement, a concrete pad known as a starter is cast before settling the formwork. The density will be approximately 45 mm to 60 mm and the dimensions will be exactly equivalent to the dimensions of the projected column. The starter is to be cured for a day or 2 so that it becomes strong to set the shuttering around it. Formworks for columns are formed with plastic, plywood sheets or steel sheets fabricated with plenty of stiffeners.
A thin film of oil or grease should be included with the inner surface of the formwork so that the column can be detached smoothly once the concrete gets solidified. Shuttering should be arranged perfectly and vertical. The diagonals should be examined to verify whether the dimensions are correct.
Formwork should be comprehensively supported with props size before pouring the concrete to resist its movement horizontally or vertically throughout concreting. The gaps close to the shuttered joints should be sealed so that there is no leakage of slurry. Column formwork is shaped and sized to the needs of a project. In order to help facilitate quality control during the pouring stage of using column formwork, clamps that are horizontal and made of either steel or timber are often used in conjunction with column moulds. Column formwork’s head is frequently employed to support beam formwork, or column formwork is cast to the bottom side of beams. The use of column formwork in conjunction with beam formwork allows for quick and precise construction.
Appropriate space should be arranged in the inside face of the shutter and reinforcement by setting up cover blocks of about 40mm. The formworks should be detached after a day of casting and if it is required to detach them previously, they should be kept up to at least sixteen hours.
Two of the major benefits of using column formwork include that it is quick and simple to assemble and that it reduces the amount of labour and equipment needed to successfully produce uniform and strong vertical concrete shapes of desired dimensions.
