Side Forms / Mold Walls: Height 1.2-1.5m, Thickness 6-12mm

Component Specifications

Definition

Side forms, also known as mold walls, are critical structural components in slipform assembly systems that create the vertical boundaries for concrete placement during continuous casting operations. These forms maintain precise dimensional control while moving upward with the hydraulic system, ensuring uniform wall thickness and surface finish in structures like silos, towers, and core walls.

Working Principle

Side forms function as moving vertical containment systems that hold freshly placed concrete in position until initial set. As the slipform assembly hydraulically rises at controlled rates (typically 150-300mm/hour), the forms provide continuous support without stopping construction, allowing concrete to gain sufficient strength to maintain shape while exposed forms move upward to new positions.

Materials

High-strength steel (A572 Grade 50 or equivalent), 6-12mm thickness, with wear-resistant facing (often AR400 steel or polyurethane lining) at concrete contact surfaces. May include thermal insulation layers for temperature-controlled curing.

Hydraulic system failure affecting form movement

FMEA Triads

Trigger: Insufficient bolt torque at connections
Failure: Joint separation leading to concrete leakage
Mitigation: Implement torque verification procedures and use locking fasteners with visual indicators

Trigger: Wear plate deterioration beyond tolerance
Failure: Poor surface finish and dimensional inaccuracies
Mitigation: Establish regular inspection schedule and maintain inventory of replacement wear components

Trigger: Hydraulic pressure imbalance
Failure: Uneven form movement causing structural misalignment
Mitigation: Install pressure monitoring systems with automatic shutdown triggers for pressure deviations >10%

Frequently Asked Questions

What is the primary function of side forms in slipform assembly?

Side forms provide continuous vertical containment for concrete during upward movement of the slipform system, ensuring dimensional accuracy and surface quality while allowing uninterrupted construction.

How do side forms differ from conventional formwork?

Unlike static formwork, side forms move continuously with the slipform system, eliminating construction joints and enabling faster construction of tall uniform structures without daily setup/removal cycles.

What maintenance do side forms require?

Regular inspection for wear, cleaning after each use, lubrication of moving parts, checking alignment and connections, and replacement of wear plates when surface imperfections exceed tolerance limits.
