MIVAN PIN AND WEDGE

✅ Purpose

To join two aluminium formwork panels (wall-to-wall, wall-to-deck, deck-to-deck, etc.)

To ensure alignment and rigidity of formwork during concrete pouring

To allow fast, tool-free locking and unlocking

🔩 Components

1. Pin

A solid cylindrical rod with a flat or looped head

Typically made of high-strength steel

Inserted through pre-aligned holes in adjoining panels

Common length: 50 mm to 75 mm

2. Wedge

A sloped/angled steel plate or tapered piece

Inserted into the pin slot to lock it in place

Applies tight clamping force to the connection

Designed for easy hammering in and removal

🧱 Working Principle

Align holes of two Mivan panels (vertical or horizontal joint).

Insert the pin through the aligned holes.

Drive the wedge into the slot on the pin.

The wedge forces the panels tightly together, holding them rigid during casting.
