Title: Testing of mechanical expansion anchors and concrete screw anchors inhollow-core slabs

For stabilization of prefabricated concrete elements during mounting obliquebraces are used. These oblique braces are occasionally attached into hollow-coreslabs. Abetong and Strängbetong are two companies using this method forstabilization and are in need of load values on what different fastenings canmanage attached into hollow-core slabs.Therefore this report is based on the testing of mechanical expansion anchors andconcrete screw anchors mounted in hollow-core slabs. The result of each fasteningis presented in tables with characteristic load values.After founding the concrete screw anchors most useful, an Excel-program wasdesigned where oblique loading can be presented.Keywords:
