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.
