Method for continuously producing a mesh-type support by welding a lower member arrangement, which comprises at least one lower member, in particular two lower members, and an upper member, which is arranged at a specific height in relation to the lower member arrangement, and has at least one diagonal member running back and forth between the at least one lower member and the upper member, in particular in a zigzagging form, wherein the welding of the at least one lower member and the upper member to the at least one diagonal member is performed by means of a lower-member welding device and an upper-member welding device, wherein the height of the upper member in relation to the lower member arrangement is changed during the continuous production of the mesh-type support. The invention also relates to a device for carrying out the method.
A method of continuously producing a lattice girder by welding a lower chord arrangement which includes at least one lower chord, in particular two lower chords, and an upper chord which is arranged at a specific height in relation to the lower chord arrangement to at least one diagonal member which extends back and forth between the at least one lower chord and the upper chord, in particular in a zig-zag form, wherein welding of the at least one lower chord and the upper chord to the at least one diagonal member is effected by means of a lower chord welding device and an upper chord welding device, characterised in that the height of the upper chord relative to the lower chord arrangement is changed during the continuous production of the lattice girder.
Apparatus for continuously producing a lattice girder comprising a lower chord arrangement which includes at least one lower chord, in particular two lower chords, an upper chord arranged at a specific height relative to the lower chord arrangement and at least one diagonal member which extends back and forth between the at least one lower chord and the upper chord, in particular in a zig-zag form, wherein the at least one lower chord and the upper chord are welded to the at least one diagonal member and the apparatus for that welding operation includes a lower chord welding device and an upper chord welding device, characterised in that the apparatus further includes a device for height adjustment of the upper chord during the continuous production of the lattice girder.
