Connecting element for connecting at least two wooden construction parts and a joint plate

Abstract

In a joint between two wooden structural members (2 and 3) there is inserted a joint plate (4), whose foot part (5) is joined abuttingly to the wooden structural member (2) by screws (7). The joint plate (4) is pushed into a slot (8) of the wooden structural member (3), whereupon connecting elements (1) are inserted in appropriate number through the wooden structural member (3) and the joint plate (4). Such a connecting element is provided at one of its ends with a boring part (11) and at its other end with a tool drive (12). The worked-off material is received by a portion (14) of smaller cross section and appropriate flutes (13). In addition, an axially secure relationship after setting is achieved with a thread (15) at one end of the connecting element. After it has been finally set, the connecting element (1) is seated in an exact fit as the fixation between the joint plate (4) and the wooden structural member (3) in its self-drilled hole.
