<p>The present invention provides a connection member for connecting a construction element to a wall and/or floor of a building, the wall and/or floor being composed of a building material having a soft structure such as gas concrete or cellular concrete (foamed concrete) and/or gypsum. One end of the connection member is provided with a thread having sharp edges and a large pitch, and the total length of the connection member is about 100 mm or more. The threaded end can be screwed into the building material in such a way that the other end can withstand a considerable tensile strain and/or shear strain.</p> |
