Abstract
A composite structure has a rod (1) and a collar (2) locked on the rod (1) and composed of two semicollars (12, 22), each extending over an angle smaller than 180.degree. and having lateral longitudinal flanges (12', 12", and 22', 22"), whereat they are linked to each other by clamping bolts (3', 3"). The flanges (12', 22') on one side of the semicollars (12, 22) adhere to each other with their facing plane surfaces (212', 222'), whereas the facing plane surfaces (212", 222") of the flanges (12", 22") on the opposite side of the semicollar (12, 22) are spaced. The rod (1) has at least one outer positioning projection (6', 6"), which is engaged in a corresponding inner positioning recess of the collar (2).
Claims15
A composite structure comprising a rod (1) with a curvilinear and tubular profile and a collar (2) fixed on the rod (1), the collar composed of two semicollars (12, 22), each semicollar having first and opposite lateral longitudinal flanges (12', 12", and 22', 22") projecting outwards, the first flanges tightened and locked together by means of a clamping bolt (3') passing therethrough, each flange (12', 12", 22', 22") of each semicollar (12, 22) being delimited by an inner surface and an opposite outer surface which are substantially plane-parallel (112', 212';
- 112", 212";
- 122', 222';
- 122", 222"), the inner surfaces of the flanges of one of the semicollars (212', 212";
- 22', 22") facing the flanges of the other semicollar, a substantially semicylindrical inner surface of at least one of the semicollars (12, 22) extends over a circular arc between the inner surfaces (211, 212";
- 2221, 222") of the flanges (12', 12";
- 22', 22") of the at least one semicollar (12, 22), characterized in that the inner surfaces (212', 222') of the first flanges (12', 22') of each semicollar (12, 22) are on one common plane, whereas the inner surfaces (212", 222") of the opposite flanges (12", 22") of each semicollar (12, 22) are on substantially parallel planes and are spaced to such an extent that, when the collar (2) is mounted and locked on the rod (1), the first flanges (12', 22') of the two semicollars (12, 22) on one side of the collar adhere to each other at the inner surfaces thereof (212', 222'), whereas the opposite flanges (12", 22") of the two semicollars (12, 22) on the other side of the collar are spaced, and the inner surfaces (212", 222") of the opposite flanges are substantially parallel.
A clamp collar for clamping a rod with a tubular profile comprising two semicollars having generally semicircular arcs of less than 180.degree. and having lateral longitudinal flanges with distinctive inner surfaces on opposite sides of the collar, with the inner surfaces of first flanges on one side of the collar touching each other and opposite flanges on a second side of the collar spaced from each other when the collar is mounted and locked on the rod, a connector holding the first flanges together with inner surfaces touching each other and a bolt extending through the opposite flanges and holding the opposite flanges inward toward each other, wherein the connector comprises a bolt and nut.
