The minimum width of a brick pillar varies depending on its purpose and structural requirements, but commonly accepted dimensions are provided below.
Typical Brick Pillar Dimensions
Brick pillar width depends on factors like structural load and aesthetic design. Here are typical minimums:
- Corner Pillars: 2 x 2 bricks (approximately 450mm x 450mm). These pillars need to be more substantial to handle loads and provide stability at corners.
- Intermediate Pillars: 1 1/2 bricks wide (approximately 340mm). These are used for support between corners and don't require as much width.
- Minimum Combined Pillar Width for Support: Some guidelines suggest a minimum width equal to 25% of each side length it supports. This varies considerably based on the load the pillar is meant to bear.
Considerations
- Structural Load: The primary factor determining pillar width is the load it needs to support. A pillar supporting a heavy roof will need to be wider than one supporting a lightweight fence. Consult with a structural engineer for precise calculations.
- Building Codes: Local building codes often specify minimum pillar dimensions. Always check local regulations before construction.
- Aesthetics: While structural requirements are paramount, aesthetics also play a role. You may choose a wider pillar for visual appeal.
- Reinforcement: Properly reinforced pillars (using rebar and concrete fill) can achieve greater strength with less width compared to unreinforced pillars.
In conclusion, while minimum widths like 340mm or 450mm are commonly used, the absolute minimum acceptable width for a brick pillar is highly dependent on local building codes and its specific structural function. Always consult with a qualified professional to determine the appropriate dimensions.
