Beam and slab formwork
Advantages of  "Lumina" slab form-system

The system can be used with few different parts in several different forming methods in order to be always adapted for the construction site conditions. This system is suitable and economic for all kinds of building projects.

1. Flex-method: Including main-beam and cross beam with the same section, adjustable for different spans by overlapping the beams.

2. Main - and side beams - method: Including beams (side and main) in the same level from the top. Different kinds of plywood can be used on the top of the beams.

a. without a drop head

b. with a drop head supporting the plywood (a strip of plywood remains during beams removing)

3. Panel-method without drop head  

The system was designed in a way that the panels can be placed on the beams without any fixing points. So it becomes a rapid assembling and disassembling system.

4. Panel method with Drop head for “early removing”.

This system not only has the same advantage of third method, but also it can be removed in a short time.

At great heights, the mentioned systems can be supported by scaffolding and shoring system which are placed on the safe soil and at average heights the props can be used for supporting.
In Lumina System design easy handling, simple transportation and light weight have been considered.
 

Design Assumption:

The slab thickness is considered 30 cm in static calculation and the allowable deflection will be checked in accordance with DIN 18202 row 7.
The props and reaction of system are designed to sustain 20 kN.
Connection of special head on the top of props can be set without screws.
The shuttering of all methods is executed from corner of a place without using additional elements.

Fillers are designed to be placed between the panels for adjusting different spans without additional support.

Panels: the panels are made from special steel profile; the weight of panel is less than 15 kg. Their sizes are 120 cm × 60 cm and 120 cm × 30 cm.
The necessary rigidity for panels is supplied by connecting the surface plate to the frame.

Beam: the supporting beam has been designed in a way that can be hanged up on the top of props by a special connection, and rotates to be fixed horizontally. Two types of this beam have been designed: with drop head method and usual method.   

Side-Beam: side beam would be the steel beam ST 140. It is designed in a way that can be used as a side beam to be connected to the main beam with a welded end plate. The upper part of the beam is covered with material (Class D) such as plastic or wood for connecting the surface plate.

Drop head for DBP-method: the plate on the drop head is narrowly designed to be able to go through between beams – halves and with sheet, plastic or plywood strip and is used as a temporary supporting.
