Detail process for positioning steel reinforcement of Neck Column
While going to bear the load of entire building, the neck columns should be developed cautiously.
Neck Column refers to the column that is located among footing and grade beam. It's also known as short column.
In the current construction sectors, all columns of a building are designed as reinforced concrete column and steel reinforcement acts as the pillar of any reinforced concrete member.
Given below, the detailed process for positioning steel reinforcement of neck column perfectly.
Steel reinforcement is also presented as rebar or MS bar or simply rod.
Column is built up on footing. Different types of footing are available for column. In this construction article, you will learn how to build up a column on a isolated footing. It will help you to arrange steel reinforcement of neck column on any type of footing.
Steel reinforcement of neck column is set on the bottom reinforcement of footing. Some footings contain two layer of reinforcement. One layer is arranged in bottom whereas another layer is arranged on top of the footing. Some footing contains only one layer of steel reinforcement that is arranged at bottom of the footing. The reinforcement of neck column is arranged directly on that bottom reinforcement.
In the image given below, there exist 3 footing and 5 grid lines. Here, the footings are presented with reference to the grid line. A sheet known as footing layout is provided in structural drawings. There will be detailed dimension for positioning footing in that drawing.
A column layout drawing sheet is also found in the structural drawing book to find out how column is arranged with reference to grid lines.
As soon as the bottom reinforcement of footing is placed, the steel reinforcement of neck column should be set.
How to arrange Steel Reinforcement of Neck Column
It includes the following three steps :-
1. Placing a stirrup on footing reinforcement
2. Fasten Column's skeleton distinctly
3. Placing column's skeleton on the Stirrup
