Things to Consider Before Constructing Practical Columns

Practical columns are elements that help tie together and stabilize masonry walls. Although not part of the building's primary structural system, their construction requires proper planning and execution to ensure they function as intended.

Before constructing practical columns, several factors should be considered to ensure the work proceeds systematically and the resulting construction is of high quality.

1. Review Construction Drawings
The first step is to examine the construction drawings and structural details.

Pay attention to the position, dimensions, reinforcement, and the connection between the practical column and the wall or other structural elements. Do not determine details based solely on common field practices.

2. Determine Column Positions
The locations of practical columns must be determined early on, particularly at:

Junctions where two wall planes meet.

Long or high wall sections.

Specific areas around doors and windows.

Points requiring additional stiffening.

Placement must strictly adhere to the building's technical plan.

3. Consider the Wall Type
The type of wall material must be identified before determining construction details.

Red brick walls and lightweight concrete block walls have different characteristics and installation methods; therefore, the connection details between the practical column and the masonry must be adjusted accordingly.

4. Determine Dimensions and Reinforcement
Cross-sectional dimensions, the number of main reinforcement bars, bar diameters, and stirrup spacing must comply with the specified technical requirements.

Do not reduce dimensions or reinforcement quantities without the approval of the responsible technical personnel.

5. Prepare Quality Materials
Ensure that the materials used meet project specifications, including:

Reinforcing steel bars.

Stirrups.

Cement.

Aggregates.

Water.

Formwork materials.

Material quality directly impacts the final quality of the practical columns.

6. Ensure Formwork Readiness
The formwork must match the design dimensions and positioning.

Ensure the formwork is sufficiently strong and stable, and will not shift during concrete pouring.

7. Pay Attention to Concrete Cover
Reinforcement requires adequate concrete cover to protect it from the external environment.

Use spacers or appropriate methods to maintain the reinforcement's position during the concrete pouring process. 8. Consider the Connection to the Building Structure
Practical columns must be coordinated with main columns, beams, tie beams (sloofs), and other construction elements.

Connections between elements must adhere to construction details to ensure the wall is properly integrated into the building system.

9. Prepare the Work Area
Ensure the work area is safe and easily accessible before reinforcement installation and concrete pouring begin.

Materials should be organized neatly to avoid obstructing work and to minimize the risk of accidents.

10. Double-Check Before Pouring Concrete
Before pouring the concrete, inspect the following:

Column position.

Formwork dimensions.

Quantity and placement of reinforcement bars.

Stirrup spacing.

Concrete cover.

Formwork stability.

Cleanliness of the pouring area.

These checks are crucial because remedial work is far more difficult once the concrete has hardened.

Practical Columns Are Not Substitutes for Main Columns
It is important to remember that practical columns and main columns serve different functions.

Practical columns help reinforce and stabilize walls, whereas main columns are part of the structural system designed to bear and transfer building loads.

Therefore, practical columns must not be used as substitutes for main structural columns.

Conclusion
Before constructing practical columns, ensure that the position, dimensions, reinforcement, wall type, materials, formwork, and connections to the building structure have been carefully planned.

Adhering to construction drawings and technical specifications ensures a more systematic workflow and guarantees that the practical columns perform as required by the construction design.
