BGW Double-wall spacer = DWAH

The double-wall spacer (DWAH) is a component installed into double walls during their production. This component significantly determines the wall thickness and concrete cover in double walls. The double-wall spacer (DWAH) is made of Ø 10mm ribbed concrete steel bent U-brackets. The legs of the U-bracket are secured at the end by a welded strut to prevent the U-bracket from bending open. Approximately 30 mm long plastic caps are placed on the base legs of the U-bracket. A socket for the base is welded in the middle of the bracket.

The height of the DWAH corresponds to the wall thickness minus the concrete cover of the first wall shell to be concreted and can be supplied in any desired concrete cover thickness. Such a double-wall spacer – if not additionally reinforced with brackets – can bear approximately 1000 kg with a 20 mm concrete cover. In this case, the concrete on the side opposite the base fails.

The M16 thread in the double-wall spacer, on which the base was screwed, can be used for attaching diagonal supports during double-wall assembly. The thread is protected with a plastic cap.
