<p>This invention relates to a connection for precast concrete elements intended for house construction, i.e.between wall-, floor-and roof-elements. The development of the connections has been carried out based on the element's premises, i.e. material consumption, structural features and building site erection. The connections consist of teeth and grooves which ensure structural strength and stiffness. The site erection of the elements becomes quick and simple, with low quantity of concrete or mortar needed at the building site.</p> |
