Abstract

A profile clamp (1) is disclosed with an annular clamping band (2) that comprises on its axial ends flanks sloped radially inwards and in the region of its circumferential ends respectively one tensioning head (5, 6), wherein the tensioning heads (5, 6) can be tightened towards one another by a head (8) of a threaded bolt (7) and a mating thread element (9).

The object is to specify a profile clamp with which a reliable coned flange connection is possible even at changing temperatures.

For this purpose, it is provided that at least one spacer piece (10) is arranged between the head (8) and the mating thread element (9).

Claims

1. Profile clamp (1) with an annular clamping hand (2) that comprises on its axial ends flanks (3, 4) sloped radially inwards and in the region of its circumferential ends respectively one tensioning head (5, 6), wherein the tensioning heads (5, 6) can be tightened towards one another by a head (8) of a threaded bolt (7) and a mating thread element (9), characterized in that at least one spacer piece (10) is arranged between the head (8) and the mating thread element (9).

2. Profile clamp according to claim 1, characterized in that the spacer piece (10) surrounds a threaded section of the threaded bolt (7).

3. Profile clamp according to claim 1, characterized in that the spacer piece (10) is arranged between the tensioning heads (5, 6).

4. Profile clamp according to claim 3, characterized in that the spacer piece (10) comprises on its radially inner side flanks (13, 14) sloped radially inwards.

5. Profile clamp according to claim 3, characterized in that in the untightened state, at least one tensioning head (5, 6) is tilted relative to the spacer piece (10) such that it initially comes to hear against the spacer piece (10) on the radially outer side during tightening.

6. Profile clamp according to claim 3, characterized in that at least one tensioning head (5, 6) is embodied in an open manner on the radially outer side.

7. Profile clamp according to claim 1, characterized in that the spacer piece (10) is arranged on the outside of a tensioning head (5, 6).

8. Profile clamp according to claim 1, characterized in that the spacer piece (10) is embodied as a bent metal sheet part.

9. Profile clamp according to claim 8, characterized in that the spacer piece (10) has a polygonal cross section.

10. Profile clamp according to claim 1, characterized in that the spacer piece (10) is connected to a tensioning head (5, 6).

11. Profile clamp according to claim 10, characterized in that the spacer piece (10) is formed from the tensioning head (5).

12. Profile clamp according to claim 10, characterized in that the spacer piece (10) is hooked into the tensioning head (5).
