FRIMEDA Lifting Anchor System

The FRIMEDA Lifting Anchor System consists of flat steel anchors, recess formers and lifting clutches. The design of the lifting clutches and anchors permit loads in any direction. One of the main benefits of this system is the availability of erection anchors for tilting of thin elements with no edge breaking. The clutches can be released either directly by hand at the clutch head or by remote control.

The Anchor
The anchors are made from a special quality of flat steel. The anchor head has a hole in which the locking ring of the clutch can engage.

Ring Clutches
The ring clutch is positioned in the recess surrounding the cast-in anchor and the locking latch is closed by hand, enabling the locking ring to engage with the anchor head. The clutch is thus connected with the anchor in a matter of seconds. The ring clutch can now be pulled in all directions to allow for lifting, rotating and pitching of the unit. There is no preferred direction. To release, open the latch and the ring clutch can be removed.

The key benefits and features for FRIMEDA Lifting Anchor System are as per below:
• 15 load classes from 0.7 to 26.0
• Numerous types of anchor
• Confusion of load classes not possible, because only those components that belong together fit together
• Erection anchors protect the concrete when shear loads are applied

Halfen Moment Precast Shoe HCC

These days, there is a significantly more economical way to assemble precast columns. The Precast Shoe provides a handy solution for connection to foundations or for linking columns together.

The advantage of the pre-fabricated system with screw connection is the quick assembly. The connection is easy to adjust and immediately loadable so that bracing is not required which results in less labor at site and enormous time gain. The system comprises of the HCC column shoe and the suitable HAB anchor bolts for the foundation base.

The principle: The precast shoes are cast in pre-cast columns, the anchor bolts are cast in foundations on site using a drilling pattern. They are joined by load bearing nuts during assembly. As a last step the bottom of the column and remaining recess are filled with non-shrinking mortar.

Application with precast elements

Invisible Connections

Traditionally, precast slabs such as stair landings used to be supported by a steel angle bolted to the wall. Installation was slow, required high degrees of accuracy, tied up the crane with costly hook- time and could only be used on straight walls. The TSS and BSF range of connectors was developed specifically to address these and other needs.

The Architect gains a smooth obstacle-free soffit with no supports on show.

The Engineer gains a robust, simple and efficient connection, which can also be used to satisfy robustness.

The Insitu Contractor does not need to incorporate connections into the wall requiring tight tolerance.

The Precaster keeps control of the connection within the factory, with no need for specialist operations on site.

The Main Contractor gains reduced crane hook-time requirements, and rapid provision of access stairs.

TSS Telescopic Connectors

BSF Telescopic Beam Connectors

For transferring heavy loads from beams into columns, walls or other beams, the ideal solution is the BSF system. These 3-part telescopic connectors have individual capacities ranging from 225 kN to 700 kN. By optionally using BSF connectors in pairs, loads of up to 1400 kN can be catered for.

87

Traditionally, beams were supported off of columns using integral corbels. Apart from being inherently difficult and costly to form, corbels reduce local headroom and can appear visually cumbersome. Using BSF telescopic connectors eliminates the need for corbels, leaving a smooth soffit and architecturally ‘clean’ lines at concrete intersections. Round, or odd-shaped columns can also easily be accommodated by the BSF system.

HEK Precast Coupler

A connection of conventional precast elements uses steel wire loops or rebend connections, which require subsequent filling of the connection joints with grout mortar; these types of connections are not immediately loadable to their full capacity. To continue construction, temporary bracing is required to ensure stability of the erected elements until the grout in the joint has cured sufficiently. In many cases considerable waiting periods have to be taken into account in the construction schedule to allow the grout mortar to cure sufficiently.

Dry connection of precast elements dispenses with grout filling the joint, substantially reducing the time and effort required for installation.

The HEK Precast coupler is a boltable precast concrete connection that uses serrated plates, which are immediately capable of longitudinal and shear loads right after installation. Furthermore it compensates for manufacturing and installation tolerances of up to 10 mm.

Advantages:
• Bolt connection
• Durable corrosion protection
• Short installation time
• No temporary bracing required
• Less crane time
• Weather independent installation
• Dismountable

HEK Precast Coupler HALFEN HEK Precast Coupler

The main advantage of this system is the quick, efficient and weather independent installation of precast elements. The connections can be subjected to their full load capacities immediately after installation. This can accelerate the construction process.

The HEK Precast coupler element, cast into concrete, is both a load transferring and connection element between elements. The precast coupler element with counter plate is designed for a bolt, that is screwed into a fixing anchor cast into the component to be connected.
