Definition and benefits of column starter
This construction video tutorial provides detail information on column starter. You will learn the process for casting of starter as well as advantages of column starter.
Starter is generally a casting of concrete material with equivalent width and length of column section and comparatively smaller height of around 10 cm. It is cast in such a manner that equal cover is left encircling the reinforcement bars of column and then shuttering of column is provided. The main purpose of starter is to fine-tune the form work of a column vertically to maintain sufficient gap among column reinforcement and shuttering.
To retain the exact position of the columns in the below slab as well as retain the column lines in number of floors easily, starter is marked.
Given below, the major benefits of a starter :
a. It is easier to set up & check the center line of the starter as compared to that of the column.
b. With the existence of the starter is exact place, fixing the column becomes stronger. Sometimes, the column form work turns out to be skew. With starter, this issue is reduced completely.
d. Once the shuttering for column is completed, bracing or supports are settled ,the verticality is examined on two sides (adjacent faces ) with a plumb bob and alignment is examined through a cotton or nylon thread.
e. The column is casted as soon as all checks are finished with the certified concrete mix.
f. The column shuttering is eliminated next day and the curing should be started. Based on the climate (temperature and humidity ), the curing is performed either by spraying water at intermediate intermissions or covering column by hessian clothe to keep it wet.
