Anchor Bolt Pull-Out Tests
Performance of the anchor bolts which connect the curtain wall to the building and transfer human impact and wind loads to the structure are of course of vital importance. The load figures given by the manufacturer assume installation in ideal conditions, whereas these rarely obtain on site. For example, holes drilled in concrete frequently hit re-bar, particularly where it is quite dense at the slab edge. Standard masonry bits are deflected and an oversized and angled hole result which be representative of the manufacturer's test installation.
The Pull-Out Test uses a simple machine to exert a calibrated tension load on the anchor and verify that it can support the design load. There are adapters for different situations and custom set-ups, when they are required, can be prepared.
