<p>This invention relates to a frame corner construction including two frame members butted together at a joint by a tensioning-eccentric connector, the two frame parts having boreholes extending perpendicularly to the joint for receiving a tension bolt, each frame part having at the end of its borehole a preferably round recess perpendicular to the borehole and open to one side face of the frame part, a round tensioning eccentric being turnably inserted into the recess of the one frame part for engagement with a clamping end of the tension bolt, the fastening end of which being held fast in the recess of the other frame part by means of a holder. Presently known frame corner constructions of this kind suffer from certain disadvantages such as overly complex construction of the tensioning-eccentric connector requiring a high degree of skill, and high cost factor. The invention seeks to overcome these problems by providing an easy and inexpensive frame corner construction. The invention provides for holding fast the fastening end of the tension bolt with an abutment stop part which is fixed on the fastening end of the tension bolt, the length of which abutment stop part in the circumferential direction of the recess which receives the abutment stop part being greater than the diameter of the corresponding borehole. Further the abutment stop part has an abutment surface which substantially corresponds to the shape of a corresponding circumferential wall of the recess, and the inner dimension of this recess in the axial direction of the boreholes corresponds approximately to the length of the tension bolt including that of the abutment stop part for adapting the tension bolt to be insertable into the boreholes from the recess which receives the abutment stop part.</p> |
