Abstract: A component having at least two parts which contact one another via their narrow faces, includes multiple connection elements which pretension the parts with respect to one another. The connection elements are accommodated in recesses formed as undercuts in the parts. The recesses are aligned transversely to the longitudinal extension of the narrow faces of the parts, the openings of the recesses being open towards the narrow faces of the parts. The connection elements are respectively formed of two wedge-shaped pieces arranged in a diametrically opposed manner. When the pieces of the connection elements are accommodated completely in the recesses, the ribs of the connection elements completely fill out the recesses, so that the parts are pretensioned with respect to one another, and a gap is prevented from forming between the parts or the closing of a previously present gap is achieved.

Abstract: A planar, angled or T-shaped building element (1) has at least two panels (2) of cross-laminated wood which are connected to one another in the narrow faces of the panels with the aid of a coupling strip (4). The coupling strip (4) has a cross-sectional shape with two ribs (5) with a trapezoidal cross-sectional shape which positively engage in undercut grooves in the interconnected panels (2). The coupling strip (4) is composed, for example, of two wedge-shaped parts (10 and 11) of mirror-symmetrical design.
