Concrete & Construction

The components behind the pour.

Concrete pouring requires forms to hold shape, stakes to set position, ties to hold faces under load, reinforcement prepared in advance, and cast-in anchors to support the structure after. Corona supplies each component as a standalone product or part of an assembly. These seven sections describe how they work together.

CONCRETE SYSTEMS

How the components work together.

Below are seven systems that show each Corona component's role in concrete construction work. Each describes the operation and identifies which products are used together.

Seven systems around concrete work.

Each section explains how the components work together and names the Corona products used.

TEMPORARY FORMING

Slab-on-ground edge and conventional formwork

Temporary forms hold a straight edge for slabs on ground, footings, and job-built timber and plywood structures. Driven stakes beside the board retain the line during setup and the pour.

Round Stakes work alongside any board type. Flat Stakes grip soft ground and board surfaces where anchoring is poor. Rebar and Square Stakes provide alternative profiles for different ground conditions. Formwork Pins use a holed retention method.

FOUNDATION WORK

Footings, foundations and cast-in connections

Footing and foundation work assembles the form edge, reinforcement fabric and cast-in steel elements before the concrete pour.

Cut Rebar is laid to the reinforcement design. Wire ties the intersections to hold the cage in place. Anchor Bolts are positioned to project through and hold the base plate after the concrete has set. Plate Washers under the nut complete the bearing assembly.

FIXED-FORM PAVING

Road, pavement, kerb and footpath edges

Steel Road Forms establish the line and profile for concrete pavements, kerbs, channels and footpath edges. Each form section remains in place on the grade through the pour.

Road Form Pins are driven through the form housing to secure it to the ground. Temporary stakes beside the fixed form hold adjacent edges during the pouring operation.

FORM TIES

Form alignment and tying

Form-tie assemblies hold opposing faces under the horizontal pressure of fresh concrete. The Tie Rod spans the gap between the faces and carries the load.

At each end, a Tie Rod Nut engages the thread and bears against a Plate Washer on the form face. Threaded Rods provide an alternative threaded connection where rod-and-plate assembly is required.

CONCRETE JOINTS

Concrete joint bar placement

Concrete pavement and slab joints use dowel bars to transfer loads across the joint as the concrete moves. The dowel sits in the joint and carries shear load from one side to the other.

Cut Bars and Dowel Bars are supplied as smooth round bars across the joint. Cut Rebar supports the concrete on either side of the joint.

REINFORCEMENT PREPARATION

Reinforcement preparation for slabs and cages

Slabs, industrial floors and reinforcement cages are laid before the concrete is placed. Bars are positioned according to the reinforcement design and held in place at intersections.

Cut Rebar is supplied to length and laid in the fabric pattern. Wire ties the intersections to hold the cage position. Cut Bars and Dowel Bars are available for joint work applications.

CAST-IN ANCHORAGE

Foundation and base-plate anchorage

Cast-in Anchor Bolts project through the foundation after the concrete has set. The threaded projection carries the base plate and equipment connection.

A Plate Washer distributes the nut load on the bearing face. Threaded Rods provide an alternative interface where rod-and-plate assembly is preferred.
