3.2.2.2. PROPPING WITH TOWERS

In beams longer than 10.00 meters, we should use the solution with towers, main beamwork and

secondary beamwork. See figure below.

The ideal option in a propping design using
towers is to mix towers with struts.

◄

Overview of the inner beam
propping with TS3 metallic
tower.

FONT VIEW

This option should also be applied with inner beams wider than 40 cm and higher than 70

cm, as seen in topic 3.2.1.1
