RMD offer a comprehensive range of tie
systems to suit your job requirements either for use with
RMD construction equipment or for your own equipment.
1. She-Bolt System
This system is ideally suited for large areas of crane
handled forms, timber or steel, as the whole assembly
of the she-bolt, tie rod and she-bolt, can be passed through
both faces of the form from one side.
Manufactured from high tensile steel with rolled BSW thread,
crimped to prevent rotation of the tie when the she-bolt
is removed. Length from 50mm in increments of 25mm up
to 600mm. 2. Rapid Tie System
The RMD Rapid Tie System is a "through" tie system in
which the bar passes entirely through the formwork, waler
plates, cone and tube assembly, locked in position with
the knock-on wing nut threaded on to each end of the tie
bar.
The expendable tube not only acts as a spacer ensuring
the correct width of wall required, but also allows easy
removal of the tie bar after pouring. Only one knock-on
wing nut has to be removed to allow quick stripping of
the tie assembly.
3. RMD Rapid Anchor
The RMD Rapid Anchor allows a cast-in fixing into concrete
to connect directly to the Rapid Tie System. It comprises
a special nut tapped to suit 15mm Rapid Tie which is encased
in plastic. A circular steel washer increases the bearing
area in the concrete. This cast-in anchor is designed
to transmit axial forces into previously cast work.
Rapid Tie She Bolt
The RMD Rapid Tie She Bolt allows the
Rapid Tie System to be used as a non-recoverable (embedded)
tie. The advantages of the 'lost' Tie and She Bolt system
are known to users of The RMD High Tensile System. A particular
advantage on double-faced formwork is the ability to pass
the assembled tie system through both formwork faces from
one side after the forms have been erected.
The She Bolt System can also be used on single face formwork,
e.g. in connections into rock faces etc., and for second
fix connections into existing walls.
The Rapid Tie She Bolt is designed to give 50mm cover
to the 'lost' Rapid Tie.
Concrete Anchor
For use with RMD 15mm Rapid Tie Bar.
Its key features are:
- Safe Working Load in suitably drilled
concrete - 80kN minimum factor of safety = 2 (from tests).
- Length of Anchor - 120mm.
- Weight - approximately 0.3kg.
- Drilled hole size - 36mm nominal
diameter (38mm max).
- Minimum concrete strength - 30n/sq.mm.
