A system of profile elements and an insertion guide element for use in such a system

摘要

The invention provides a system of profile elements for the construction of frame structures, said system comprising elongate hollow profile elements (1,2,3;20,21) with at least one longitudinal channel with substantially rectangular cross-section and joining elements for providing angle joints between two such profile elements, said joining elements comprising a centring and load transferring insertion guide element (4;22) with a substantially rod-shaped shank part (5;23) for insertion with comparatively tight sliding adjustment into the mouth of said channel at a cut surface in one of said two profile elements, and a substantially circular-section-shaped head part (6;25) integral with the shank part and a first side wall portion (7;35) which joins one (8;33) of two opposite parallel sides of the shank part and forms an angle (v) therewith corresponding to a prescribed maximum angle for said predetermined angle range, between which side wall portion and the other (11;34) of said opposite sides of the shank part the head part has a cylindrical wall section (9;36) with a radius corresponding to the width of a channel in the second of said two profile elements. <IMAGE> <IMAGE>
