Slab Anchor Head Wedge for 4 Strands

A 4-strand slab anchor wedge is a post-tensioning component designed to secure 4×15.2mm steel strands (ASTM A416 standard) in thin concrete structures. It transfers strand tension evenly to concrete, used for bridge decks, building slabs, and parking garages.

Key Features (Industry-Standard)

· 4-Strand Fit: Precisely spaced holes for 15.2mm strands (uniform load distribution).

· Standard Materials: Carbon steel anchor plate (45# steel); heat-treated alloy steel clips (20CrMnTi).

· Self-Locking Wedges: Split clips grip strands/anchor plate during tensioning (stable anchorage).

· Slab-Optimized: Compact flat plate (~100mm dia × 50mm thick) fits thin concrete.

· Corrosion Options: Galvanized (general use); 304/316 stainless steel (corrosive environments).

Typical Specs (15.2mm Strands)

Common Uses

· Bridge deck transverse prestressing

· Building floor slab reinforcement

· Parking garage prestressed flat slabs

Quick Installation Steps

1. Embed flat ducts; align with anchor plate.

2. Thread 4 strands; insert clips.

3. Tension strands with a jack (per specs).

4. Grout ducts post-tensioning.
