Spartan Sideform Connection / Joining

Spartan Permanent Joiner Sleeves

In the process of forming precast panels and structures it is almost unavoidable to have to cut sideform sections and lengths to make up specific lengths of edgeform on a mould or internal opening and penetrations.

This results in damage to sideforms and hence costly waste. The Spartan Sideform is designed to be very easily and cost-effectively permanently joined so that smaller pieces can be joined to make up longer lengths again without effecting the operational capabilities or quality of finish of the sideform. This drastically reduces long-term costs and operational material waste and makes the SRB Sideforms / Edgeforms one of the most cost effective alternatives available.

The Spartan Sideform has internal rib guides that suit standard stainless steel square hollow section. The stainless steel sleeves are inserted into the ribbed guides in one end of the Spartan Sideform, leaving a section (around 100 mm / 4 inches or more) protruding from the end. The sleeves are then either pop riveted or screwed into position in the specific purpose grooves at the rear of the sideform (designed to accommodate the screw or pop rivet head).

The sideform length to be joined is then aligned with the protruding stainless steel sleeves and the two sections of sideform pushed together to fully abut. The internal sideform ribs ensure that the two lengths of sideform perfectly align in both planes. Once abutted, pop rivets or screws are once again used to secure the fitted / joined piece.

Spartan Production Connector Plates

During the production process it is necessary to temporarily join two lengths of sideform / edgeform to produce the required length of the panel or structure being cast. This however is not a permanent join particularly when excessively long sideform lengths are required and permanently joining the sideforms would thus make them too heavy and impractical to handle.

SRB utilises Steel Connector Plates in purpose built channels at the rear of the sideforms to simply, quickly and very cost effectively join lengths of sideform for the duration of the manufacture process.

The connector plates are generally left / stored in one end of a standard length sideform simply by turning the knob on the connector plate to lock it in the sideform channel.

The two sideform lengths being joined are abutted end to end and the connector plate is simply released and pushed into the channel of the sideforms being joined so that the plate is engaged in both sideforms. The knobs are then easily hand tightened securing the two sideforms to one another for the length of the the production process.

Once the concrete is sufficiently cured for stripping the connector plate is loosened and pushed fully into one sideform and again locked to remain in that sideform. This disconnects the two joined sideforms enabling them to be separately stripped away from the cast member.
