Standard frames are cross braced to provide increase strength and limit differential settlement of legs in soft ground. Additional special frames are not required.

A typical fl at slab/capital design shows clearly the requirement of only two types of tableform to be used for typical bay.

Steel packers are used in tableform for difference in thickness between flat slab and capital to reduce convention timber box-out.

Horizontal Formwork
Using standard components such as heavy duty frames, prop frames, steel primary and secondary bearers virtually assures just about any height and size configuration required and on a limited number of re-uses assures the contractor of the most cost efficient system.

Transfering of tableform
2-6
Transport Wheel (Trolley)
Transporter
Lower the table slightly to break the bond
of the concrete by turning the prop collar
downward( approx. 50mm).
Push transporter into position and set until
it supports the tableform.
Once transporter carries the tableform
weight, release the prop inner by taking out
the prop pins and pusing the prop inner into
the frame.
The transporter can then be removed once the tableform rests on the transporter wheel (trolleys).

2-7
Insert 4 numbers of transport wheel (or 6
when required) underneath the main
corner of tableform bottom prop inner.
Lower the transporter which supports the
tableform slowly.
Once the tableform rests on the transport wheel, the tableform can be pushed into the loading platform.
