Props |
................................................................................. |
|
Adjustable props are economical and popular instruments used to support the concrete elements. They provide the best temporary supports for all purposes. They are: |
|
|
Economical to hire or buy |
|
Easier and quicker in erection |
|
Provide safe load supporting |
|
|
CSFF is one of the leading manufacturers and exporters of adjustable props, recommended by major construction companies around the world.
The most important part of the props are the threaded portion called the Collar. The Collars are galvanized and include a high tensile steel pin. Both were designed to be rust-free and easy to adjust. |
|
Props are manufactured in two categories |
|
|
Medium Duty Props ( 2.0 mm thickness, inner and outer tube) |
|
Heavy Duty Props (3.1 mm thickness, inner and outer tube) |

|
Props should always be erected vertically and loaded concentrically. |
|
|
Props should always have the correct high tensile pin fitting. |
|
|
Failure
of props can result if reinforcing rods, tie rods or materials which
may be inferior in quality or smaller in diameter are used instead of
high tensile pin. |
|
|
Ensure that the props inner and outer tubes are straight, free from creases and telescope freely. |
|
|
Bent props should not be used. Ensure that both head and base plates are flat and perpendicular to the tubes. |
|
|
Ensure
the soffit formwork is adequately restrained from horizontal movement,
either from containment by the permanent structure or by diagonal
bracing. |
|
|
To improve load bearing capacity, lace props with tubes and fittings. |
|
|
Wherever suitable, tie the lacing into the permanent structure. |
|
|
Props should never be placed on top of one another to support high slabs. |
|
|
Never throw the props down to the ground from any height. |
|
|
Always handle them carefully. |
|
|
|
As a safety precaution, where props exceed 2.75 m in height, it is advisable to make use of lacing in both directions at a position one third of the distance up the prop extension. |
