Roof eave anchor bolt fixture - has bolts positioned on masonry top before casting into subsequently applied concrete layer

摘要

The process, for anchorage of eaves purlins in a roof structure, involves use of set bolts anchored in the sill (1), masonry (2) and connected to the eaves purlins (4). The set bolts (5) are placed in position on top of the masonry before application of the top layer of concrete, and cast into this layer when it is laid. The bolts are pref. fitted with projecting support feet (6), before being set in position, and these feet may be placed below the reinforcement of the top layer of concrete. A completely correct fixture of the set bolts is ensured in all circumstances, removing any danger of the roof being carried away in high winds. The interval between bolts can be selected according to local needs.
