Suspension components

AR Suspended Connection

With a threaded joint system, concrete facade elements or brackets for walls built on site are suspended from the structure of the building. AR suspension parts are used for attaching shell elements and masonry brackets to the building’s frame.

In addition to the structure's own weight, the suspnesion parts transfer wind loads. The steel parts of shell elements can also be used for lifting the elements and connecting overlapping elements together via dowel joints.

The suspnesion parts transfer vertical and horizontal forces. These forces must be considered in the design of the supporting structure. For operational purposes, the parts are positioned so that equal stress is formed on the parts. Height adjustment is done via a threaded rod, and before installation, it must be ensured that the drawn angled threaded rod is equipped with a locking nut.

The suspension parts are sized for the supported structure's own weight and wind loads. If the suspension parts are also loaded with vertical live loads, this must be separately considered in the sizing of the anchoring parts. ARKL fastening plates can be used for transferring more than just the element's own weight only with a separate analysis by a structural engineer, as vertical live loads reduce the reliability of blunted grips relative to the concrete's fracture cone.

The ARM compression part acts as a compression tie for the shell element's ARR anchor part, transferring both the compression loads caused by the element's suspension and wind to the frame structure. The connection areas at the top edge of the element are insulated after the diagonal tie is installed, so the adjustment of the ARM compression tie can be done in the insulated state by tightening the threaded rod. Finally, the lock nut is tightened against the shell element.

AR Masonry Support

Products

A-BEAM®

A-BEAM® and Anstar’s connection technology form part of the frame system, offering cost-efficiency and flexibility for construction.

Ties

Diagonal ties are used in concrete sandwich panels to connect the outer skin with the inner skin through the insulation layer. The ties transfer the self-weight and wind loads of the outer skin to the inner skin.

Fastening plates

Fastening plates are used on cast-in-place and prefabricated structures to provide a mounting surface for welding.

Suspension components

Anstar has developed bracket and support systems for efficient and affordable construction. The connection pieces are easy to install both at the prefabrication factory and on site.

Balcony connections

Balcony hinges are used to transfer horizontal forces from the balcony to the building frame. The hinged connection enables vertical movement.

Rebar bolts and anchor bolts

high-quality rebar and anchor bolts are responsibly made with recycled steel. There are two different basic types of bolts: ATP- ja AHP® rebar bolts and ALP® anchor bolts

AEP® hidden bracket

AEP® hidden brackets are used to fasten a concrete element beam or Anstar A-BEAM® to the side of a concrete element column, wall or another beam. 

AOK® support

The AOK® support is used in a hollow-core slab floor opening as the load-bearing structure for the end of the slab. The AOK® support has been granted a patent, which enables exclusive rights to the most cost-effective support in the market.

Column shoes

Column shoes are used in light- and heavy-duty column extension and foundation connections; wall shoes are used in the tension connections of stiffening wall and shaft elements, retaining walls and earth pressure walls that stiffen the building.

Rebar couplers

Rebar couplers are used for joining rebars with full tension capacity. The ends of bars to be joined are provided with threads, and the bars are joined using a coupler sleeve that transfers the force on the rebar across the connection.

Bracing connections

ADE® and ADK® bracing connections are designed for stabilising the concrete element frame. These connections
are used in the joints between concrete columns and stabilising steel bracings.
