PFEIFER-MoFi 16

Easy and professional fastening of braces to double wall elements!

Particular attention must be paid to the reliable assembly of precast elements, always bearing the building process and the on-site safety of the workforce in mind. So-called braces, which are fastened not only to the ground, but also to the precast element, are used during the assembly of precast elements. They must be able to reliably absorb stress caused by winds during the entire assembly period, for instance.

Today, concrete screws approved by the building authority are usually used for ground anchoring. So far, there was no approved product for anchoring braces to the precast element, in particular for double wall elements with their extremely thin shells of 50 mm, which was also able to absorb the load effects occurring at the required height and with the appropriate safety levels.

The PFEIFER brace anchor MoFi 16 has been specially developed for use for fastening the brace, and has a corresponding building authority approval. This approval ensures that the planner is given reliable information regarding the load-bearing capacity of the anchoring of the brace for verification of assembly safety on the building site, and that these load-bearing capacities are of a sufficient level. This is important, as of course, the selected brace only functions in combination with the high-performance anchoring means used. This not only applies to the base point, but also to the anchoring in the precast element, as the system only has the same load-bearing capacity as the weakest link.

The PFEIFER brace anchor MoFi 16 is fastened to the formwork with the appropriate PFEIFER accessories either by gluing, nailing or magnet fixing at the precast company. The installation of additional reinforcement beyond the structural minimum standard is not necessary. The formwork fastening elements can be removed after demoulding of the concrete elements, and the screw-in opening of the MoFi 16 is exposed. The braces are then normally used after transport of the elements to the building site during erection, for example of the double walls. These can now be fastened over the MoFi 16 to the head point with a conventional, suitable M16 bolt of grade 8.8 and a washer. The concrete screws already mentioned above are also used at the base point. Once complete, this system is now able to absorb the effects occurring during assembly, as specified by the planner. After removal of the braces, the small recess can either be filled with suitable material or covered using the PFEIFER plug MoFi 16. The specific design of the product for this application led to the use of suitable materials and systems. One example is the use of an M16 standard thread within the anchor. This enables the use of conventional standard bolts M16 of grade 8.8. Therefore no special bolts need to be purchased, but rather it is even possible to obtain suitable bolts at short notice from a specialist store. Reliable assembly of the precast components is therefore ensured.

In accordance with the motto “We aren’t satisfied with simply fulfilling the requirements”,  PFEIFER can offer the customer a high-performance, reliable yet economical solution for the fastening of braces.

Fasten your precast components reliably and economically.
