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.
Tips for the field
When support frames are used, the following must be considered:
- Foundations and floor slabs etc. must be able to resist the transmitted loads (a static calculation might be required).
- The dimensions of the anchors and the layout have to be planned in detail before the construction start.
- In order to avoid overloading the formwork, the support frames should be attached to the panels close to tie holes.
- The ‘opposite side’ of the single-sided formwork (e.g. existing wall) must be able to resist the concrete pressure.
- As a rule, anchor bars must not be welded, heated or deformed.
