Support Frame STB
The safe support system for single-sided formwork
What was an exception years ago is a routine matter today: single-sided walls. For example when concreting against existing structures or for the skinning of pits, for retaining walls or for shafts and tunnels.
With single-sided walls, the total concrete pressure must be transferred from the formwork into the structure or into the ground. Meva support frames offer a safe and economical solution with an anchoring system that is built into the foundation, the floor slab or the slab.
The following must be considered when using support frames:
- Foundations, floor slabs etc. must be able to resist the transmitted loads (a static calculation may be required).
- The anchor dimensions and the layout must be planned in detail before the start of construction.
- In order to avoid overloading the formwork, the support frames should be attached to the panels, close to the tie holes.
- As a rule, anchor bars must not be welded, heated or deformed.
- The ‘opposite side’ of the single-sided formwork (e.g. existing wall) must be able to resist the concrete pressure.
