Ancon CombiDeck Steel Decking

Developed for use with the permanent metal deck shuttering, this system is manufactured in zinc coated mild steel with a stainless steel channel and supplied with an integral channel section that accepts standard Ancon 'T' head bolts.

The serrated and slotted edge of the Ancon brackets allow for vertical adjustment and the built-in channel will provide virtually limitless horizontal adjustment.

Features and benefits:

• Options include a full system manufactured from stainless steel.
• Supplied in a variety of heights to suit the floor thickness.
• Corner assemblies and special units are available to suit particular applications.
• The stainless steel channel is Ancon 30/20, positioned 55 mm below the top. Ancon 38/17 or 28/15 channel can be used to suit smaller loads.
• The thickness of the floor slab will determine the capacity of the support system. A 130 mm thick slab will limit the height of a single skin of brickwork to 4 metres.
• Thicker slabs will permit more masonry to be supported.
• Welded CombiDeck corner units are available for external corners, where it is not possible to fix directly to a corner column.
• Shims can be included between the bracket and the frame, up to a maximum thickness of the outside diameter of the fixing bolt, or 16 mm, whichever is less.
• Ancon extension plates can be used to increase the bearing for the brickwork.

Fixing CombiDeck to steelwork:

• The bottom of the CombiDeck should be fixed to the top of the steelwork at 225 mm maximum centres.
• Fixing straps are supplied to restrain the top edge of the CombiDeck. These will be positioned within 100 mm of each butt joint and at centres not exceeding 450 mm.
• Straps are supplied in 2 metre lengths for cutting and bending on site.
• The outer edge of the CombiDeck can extend beyond the steelwork up to maximum distance of 100 mm. If a greater distance is required, both the metal deck and the CombiDeck will need to be propped.
• A minimum of 125 mm should be left between the outer edge of the CombiDeck and the metal deck to allow sufficient space for the channel anchors and local reinforcement.
• Where the deck is at 90º to the CombiDeck, the open troughs must be filled to retain the wet concrete.
• Butt joints between lengths of CombiDeck should be taped to prevent concrete leakage.
