A method for manufacturing a formwork element 10 for concrete structures, uses a formwork element having a base body 12 of hollow profile construction with an outer side 14 designed as a form lining. The base body 12 is formed by at least two interlocking sub-segments which are permanently connected to one another at their interlocking edge areas. The sub-segments, such as edge segment and intermediate segment 16, 18, which are advantageously produced through extrusion, are hooked to one another to form an inseparable unit in the connected state. |

1. A method for manufacturing a formwork element for concrete structures, the formwork element having a base body of hollow profile construction with an outer side constituting a form lining, wherein the base body has at least two interlocking sub-segments which are permanently connected to each other at mutually interlocking edge areas by means of a hooked connection formed proximate inner and outer sides of the sub-segments, thereby constituting an inseparable unit, wherein the hooked connection extends through a large fraction of the entire length of the base body or through a large fraction of an entire length of the inner and outer sides of the base body, with the hooked connection having a locking groove disposed on one sub-segment proximate the inner side of the base body, the locking groove capturing an inner wall section of the other sub-segment, wherein the locking groove is partially covered by an inner wall leg of the sub-segment having that locking groove, the inner wall leg protruding parallel to the inner side of the base body, wherein the locking groove has a groove bottom, one end of which is disposed on a side wall of the sub-segment, and a groove flank angled toward the inner side of the base body, a profiled inner wall section of the other sub-section having an offset edge area which engages below the inner wall leg as well as an integral profiled strip which protrudes into and at a side of the locking groove towards the groove bottom to seat over a large area on the groove flank in a locked position of the inner wall section, wherein the hooked connection has a snap-on hook proximate the outer side of the base body and disposed on one sub-segment, which snaps into locked engagement with a locking element disposed on the other sub-segment, the method comprising the steps of:
a) introducing the sub-segment having the offset edge area into the locking groove of the other sub-segment until the offset edge area is guided beneath the inner wall leg of the other sub-segment; and b) establishing, following step a), the hooked connection by pivoting one sub-segment relative to the other sub-segment under forced guidance of the offset edge area of the inner wall section and in a hinge-like manner in the locking groove until the snap-on hook snaps into locked engagement with the locking element, thereby bringing the offset edge area of the inner wall section of the one sub-segment into a locked position in which the profiled strip of the one sub-segment seats on the groove flank of the locking groove of the other sub-segment. |
