Types of Shoring and Scaffolding
In building construction, temporary structures are often required to support walls, trenches, and workers during construction or repair work. Shoring and scaffolding are two such important systems. In the ITI Draughtsman Civil trade, understanding their types and applications is essential for ensuring safety and efficiency at the construction site.
Shoring is used to support unstable structures or excavations, while scaffolding provides a working platform for workers at height.
Shoring
Shoring is a temporary support provided to structures to prevent collapse during construction, repair, or alteration. It is commonly used when walls become weak or when nearby excavation affects the stability of a building.
Types of Shoring
1. Raking Shoring
Raking shores are inclined supports placed against a wall to provide lateral support.
- Used for weak or bulging walls
- Provides temporary support during repairs
2. Flying Shoring
Flying shores are horizontal supports used between two adjacent buildings.
- Used when intermediate support is not possible
- Supports walls of neighboring structures
3. Dead Shoring
Dead shores are vertical supports used to carry loads of structures temporarily.
- Used when lower parts of walls are removed
- Supports beams and floors
Advantages of Shoring
- Prevents collapse of structures
- Ensures safety during construction
- Allows repair and alteration work
Scaffolding
Scaffolding is a temporary structure used to provide support and access for workers and materials during construction, maintenance, or repair work at height.
Types of Scaffolding
1. Single Scaffolding
Also known as bricklayer’s scaffolding, it is used for brick masonry work.
- Consists of vertical posts and horizontal supports
- Economical and simple construction
2. Double Scaffolding
Also called mason’s scaffolding, it is used for stone masonry work.
- Provides stronger support
- Two rows of vertical supports
3. Cantilever Scaffolding
Supported on one side only, used when ground space is limited.
- Used for high-rise buildings
- Requires careful design
4. Suspended Scaffolding
Platform is suspended from the roof using ropes or chains.
- Used for painting and repair work
- Adjustable height
5. Trestle Scaffolding
Supported on movable ladders or tripods.
- Used for indoor work
- Suitable for low heights
6. Steel Scaffolding
Made of steel tubes and fittings.
- Strong and durable
- Easy to assemble and dismantle
7. Patented Scaffolding
Ready-made scaffolding with special fittings.
- Quick installation
- Adjustable platform levels
Components of Scaffolding
- Standards: Vertical members
- Ledgers: Horizontal supports
- Putlogs: Support platform boards
- Braces: Provide stability
Safety Measures
Proper safety measures must be followed while using shoring and scaffolding:
- Ensure strong and stable support
- Use quality materials
- Provide guardrails and safety nets
- Regular inspection
Importance in Construction
Shoring and scaffolding are essential for:
- Safety of workers
- Supporting structures during construction
- Providing access to higher levels
Importance in Draughtsman Civil Trade
Knowledge of shoring and scaffolding helps draughtsmen in planning construction activities and preparing safe working drawings. It also helps in understanding temporary support systems.
Conclusion
Shoring and scaffolding are important temporary structures used in construction to ensure safety and support. Understanding their types and applications is essential for proper construction planning.
For students of the ITI Draughtsman Civil trade, this knowledge is crucial for ensuring safe working conditions and successful execution of construction projects.
