<p>The appliance, for attachment of loads to reinforced concrete building structures, comprises a box-sectioned anchor bar with a slit for suspension of screw heads from outside, and with anchor units welded at intervals on the cross arm which links the shanks. Here the anchor units (5) are in the form of ribbed reinforcing bars. These may have a load bearing connection with the reinforcing rods (7) in the concrete structure and be bent out sideways at their open ends, either across the longitudinal line of the anchor bar (1), or along this line. The anchor bar may be borne by the concrete structure steel reinforcement. The anchors permit accurate static determination of the load bearing capacity of the anchorage.</p> |
