Abstract [en]

This report aims to outline a number of attachment methods for the geophones used in vibration measurements. On behalf of Bjerking AB and their department for environmental control and vibration, a new attachment method has been developed that works on today’s building designs.

Suggested mounting methods include some methods with their main stronghold in the foundation’s outermost layer and some with mounting in the concrete inside the foam. The best method is to drill through the foam and with a concrete screw - suitable for concrete drilling without plug - and anchor the geophone in the concrete. Due to the difficulty to get a hold of these screws with the required length and diameter for the current case, a similar approach with available material has been developed. This method includes a hammer drill, a threaded rod, an expander and two nuts.

The conclusion drawn is that the attachment of the concrete is preferable and that this can be achieved with relatively simple means. Other methods require extensive knowledge of the building’s design as well as advanced and time-consuming tools.
