Adjustable Construction Props
Construction props are adjustable metal temporary supports that hold up slabs, beams, walls, and trenches in concrete forming until the concrete has cured to sufficient strength, or buildings and structures during repair until the permanent structures can take over the load. Thus, the construction props include:
- Adjustable formwork props for concrete shoring and telescopic
- Building props for structural support in repair and construction
Construction Props For Formwork
Props are adjustable shoring parts of the formwork system. They support formwork panels, formwork beams (like H20 timber beams and aluminium beams), and plywood in concrete slabs, beams, and walls. Compared to shoring scaffolding in formwork, the props are telescopic and standard independent, which is more efficient and easier for formwork construction.
Construction formwork props, known as shuttering props, include slab single props, push-pull single and double brace props, and trench props according to the design and function.
Slab single props are the most popular construction props for concrete formwork. They are used to support concrete slabs and beams vertically in construction.
Push-pull props brace the formwork panels in the wall and column formwork concrete. Push pulls can be single-braced or double-braced.
Trench props are short and adjustable to brace the trenches during construction forming.
Construction Props For Building Repair
Construction props used to support permanent buildings and structures temporarily during maintenance are called building props. Building props are one type of scaffolding prop, which is adjustable and easy to set up anywhere that needs support in repair and maintenance processes.
Light Duty, Medium Duty and Heavy Duty Construction Props
According to the construction props’ designed load capacity, there are light-duty, medium-duty, and heavy-duty props.
Take a 4m height construction prop, for example.
- Light-duty 4m props are designed to take a load of 12.8-17KN (A40 and B40 Class 4m Props)
- Medium-duty 4m props are designed to take a load of 25.5 KN (C40 Class 4m Props)
- Heavy Duty props at 4m are designed to take loads of 34 KN and 51 KN (D40 and E40 Class Props)
Mark: Refer to EN1065 standard.
Steel and Aluminium Construction Props
Construction props are adjustable metal props. According to metals, there are steel props and aluminium props. Steel props are made of steel tubes and structures, while aluminium props are made of aluminium tubes and profiles.
- Steel props are heavier in self-weight, take more weight, and are cheaper. They are widely used in most constructions.
- Aluminium props are lighter in self-weight, convenient to handle, and less prone to rust, but they are more expensive than products made of steel.
Construction Props Adjustable Height Range and Sizes
Construction props are adjustable in height. Thus, prop sizes range from minimum to maximum height. For example, the 2-3.5m prop size means the props are adjusted from a minimum of 2.0m to a maximum of 3.5m.
To simplify things, construction props are named according to their maximum height in sizes. So, 2-3.5m props are called 3.5m props.
According to the EN1065 construction prop standards, the props are listed in seven sizes according to the maximum height: 2.5m, 3.0m, 3.5m, 4.0m, 4.5m, 5.0m, and 5.5m.
Some special props, like acrow props (a type of formwork prop with 3.2mm inner and outer tube invented in the UK), have sizes 0# (1.07m to 1.82 m), 1# (1.76m to 3.12m), 2# (1.98m to 3.35m), 3# (2.59m to 3.96m), and 4#(3.27m to 4.88m).
More than standard prop sizes, there are various customised sizes and ranges for each project requirement.
Construction Prop Parts
Construction props are modular shoring posts used for construction shoring and support. They consist of inner tubes, outer tubes, prop sleeves, prop nuts, prop lock pins, bottom and top plates, etc.
- The inner tubes of the props typically have holes. Lock pins are inserted inside the holes to fix the props at a required height.
- Outer tubes have threaded and screwed sleeves and nuts, which can be adjusted slightly to secure the structure precisely.
- The bottom plates are the feet of the props, standing on the ground.
- Top heads connect to the shoring structures directly, receiving weight from the shoring system and structure.
Construction props are used for different functions. Thus, the top heads are important and designed according to the structure’s shapes and requirements.
According to the top head types, there are construction props with flat top plates, flat base plates, U heads, fork heads, J heads, or cross heads.
Shoring Props VS Post Shores
Shoring Props
Adjustable Shoring Props are one of the lightweight construction steel props with parts of handled prop cups.
Typically, the shoring props have a 40/48 and 48/56mm diameter inner and outer tubes.
Post Shore Props
Post-shore props are construction props with a threaded sleeve and prop nut. They have bigger inner and outer tube diameters than the shoring props, including 48/60mm, 60/71mm, 63/76mm, and 76/89mm.
Prop nuts of the post shore props can be cast iron, cast steel, or drop forged.
Panted, Galvanised and Coated Construction Props
Steel construction props need surface protection to prolong their life in construction.
There are painted, galvanised, and powder-coated steel construction props.
How to Use Construction Props
- Place Props at the point that needs to be supported
- Extending the inner tube of the construction props to just shy of the designed height
- Insert locking pins into the holes of the inner tube, fixing the prop height.
- Use the screw collar(prop nut or prop cups) to adjust the height of the props precisely.
- Put a prop tripod at the feet of the props to make the propping system more stable.
