Abstract

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.

First claim

We claim:

1. A method for manufacturing a formwork element for concrete structures, the formwork element comprising:
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 segment 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 sub-segments each being hollow-profile structures,
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.

2. The method of claim 1 , wherein the sub-segments are designed as edge segments and/or intermediate segments.

3. The method of claim 2 , wherein the edge segments and/or intermediate segments have differing widths.

4. The method of claim 1 , wherein the sub-segments have at least one side wall which subtends an angle with the outer side of less than 90°.
