SDG Precast Accessories: A Guide for Manufacturers

In the world of precast concrete production, the use of BT Innovation innovative products such as shuttering magnets MagFly® AP, shuttering support systems Multiform, magnetic formers, nailing plates and chamfers have become increasingly prevalent. These magnets, play a vital role during the manufacturing process of precast concrete elements. With advancements in technology and materials, these magnets offer unparalleled holding force-to-mass ratios, revolutionising the precast industry by enhancing both efficiency and safety.

Double wall precast concrete sandwich panels consist of two concrete shells separated by an insulated void. Holding these sandwich panels together requires specialised precast accessories that maintain structural integrity and thermal performance. While steel trusses can connect the shells, they can create undesirable thermal bridges, reducing insulation efficiency. Instead, fiberglass double wall connectors like ThermoPin anchors eliminate this issue by preserving the continuity of insulation. Other accessories like double wall anchors, dowels, and DWAK Rockets spacers serve critical functions in transporting, bracing, and manufacturing double wall panels. With specialised products for handling, connecting, and producing, SDG offer the necessary accessories for effective double wall precast construction.

Precast wall and floor slab connections are critical for ensuring structural stability in precast construction. These connections link precast wall panels to each other and to floor slabs.

Common precast connection systems for connecting walls include PVL loop boxes and loop rails, cast into panels, after removing the formwork, the cover is removed, the loops are opened, and a vertical rebar installed into loops. BT-Spannschloss turnbuckles also efficiently connect precast walls while enabling precise assembly.

With robust products for joining wall to wall or walls to floors, SDG offer reliable precast structural connections to unite building components into an integrated structure. Careful design and installation of these accessories creates durable precast buildings to safely withstand loading.

Socket Lifting System

The Threaded Socket System uses conventionally threaded parts for adjustable lifting and anchorage of panels. With socket safe working loads from 500kg to 12500kg, it enables lifting diverse concrete elements from beams to walls. Multiple socket types allow manufacture and installation of panels with demoulding, loading, and tilting.

Lifting With Spread Anchor System

The Spread Anchor System is an industrial scale solution for high-capacity repeated handling. Quick action clutches from 0.7t to 22t simplify connections, prevent mismatches, and uniquely flip very narrow solid and insulated wall panels.

Spherical Anchor Lifting Systems

Spherical Anchor Systems efficiently manoeuvre precast units of varying sizes with an easy engage and release mechanism. This rapid attachment system enhances productivity, especially for repetitive positioning tasks.

Plastic spacers serve a vital function in precast concrete manufacturing. Precast requires maintaining strict concrete cover over reinforcement steel per code requirements. Plastic’s versatility adapts spacers to the diversity of precast elements and directions of support. Spacers centrally position rebar within moulds before pouring, whether in vertical or horizontal orientation. This ensures proper spacing that prevents defects from inadequate cover. With characteristics suiting an array of specific precast applications, plastic spacers align steel exactly as needed prior to concrete placement. Their adaptable performance and durability under wet concrete conditions drive extensive use for achieving quality in precast construction.

Galvanised Spiral Tubing is used for diverse applications in both precast and cast-insitu concrete projects. Tailored to facilitate precast connections, service penetrations, and the creation of formers for starter bars and post-tensioning ducts. These robust metal ducts allow for effortless casting into concrete, providing a seamless integration that can be securely tied into position alongside the reinforcing steel.
