The ultimate rigid-element frame

Heavy-duty precast concrete frames, as seen in paper mills, factories, or stadiums, always require heavy‑duty connections. However, solutions are often designed only for pin connections or for moderate- if not small-load cases. This might be a limiting factor in the decision to design a precast frame. Other construction methods, such as cast-in-situ, will be more time-consuming and rendered impossible by tight construction schedules.

Peikko offers the ultimate solution for building a rigid column–beam precast concrete frame. You can design your column–foundation and column–beam connections to be stiff against torsion without additional stiffening structures. With the aid of beam shoes, column shoes, and anchor bolts, assembly of the elements is very quick, easy, and safe. No temporary bracing is needed: the connection transfers assembly-time loads immediately when the nuts are tightened. Good adjustment possibilities guarantee accuracy in the frame structures.

How does the Peikko solution work?
A column with cast-in column shoes is fixed to anchor bolts that are cast into the structure below the column. A beam with cast-in beam shoes is supported on corbels and fixed to anchor bolts cast horizontally into the column. Fixing is achieved with nuts and washers screwed to the anchor bolts. The joints between elements should be grouted before loading of the structures above. When the grout has hardened, the joints function as a rigid reinforced-concrete structure.

Peikko’s anchor bolts, column shoes and beam shoes have gone through rigorous test programs. The system is widely approved in various countries. Peikko also offers free design software and technical support to make the use of the system as easy as possible – from design to erection. Let us help you make the ultimate rigid-element frame!
