Abstract
A support structure for a frame formwork panel including a support structure and a formwork skin connected to the support structure, the support structure having two longitudinal edge girders and two transverse edge girders, wherein a corner connecting piece which is welded to the two respective edge girders is provided in at least some of the corner regions of the support structure where a longitudinal edge girder and a transverse edge girder come together.
Claims18
A support structure for a frame formwork panel, the support structure comprising:
- two longitudinal edge girders comprising at least a first longitudinal edge girder and two transverse edge girders comprising at least a first transverse edge girder, wherein the two longitudinal edge girders and the two transverse edge girders each define, on respective rear sides, a flange projecting toward a center region of the support structure;
- a corner connecting piece, connected by welded connection to the flange of the first longitudinal edge girder and the flange of the first transverse edge girder, disposed in at a corner region of the support structure where the first longitudinal edge girder and the first transverse edge girder meet,
- wherein in at least one of the following weld connection positions:
- a) the welded connection between the longitudinal edge girder and the corner connecting piece;
- b) the welded connection between the transverse edge girder and the corner connecting piece;
- or
- c) the welded connection in a region of miter surfaces of the first longitudinal edge girder and the first transverse edge girder,
- the welded connection is configured as a plug weld connection or as a recess weld, at least one of the flanges defining a recess at an edge of the flange and/or in the case of the plug weld joint position(s) a) and b), the plug weld joint defines a hole in the flange of the first transverse edge girder or the first longitudinal edge girder.
