of the girder 5 are square shaped the coupling element 9 is mounted on the end of the girder 5 at the bottom edge of the girder 5 it fastens to an hq girder flange 10 the connecting member 22 is also provided with a flange plate 17 matching the flanges 10 of the hq girder the flanges extend continuously over the length of the entire girder system the box of connecting member 22 may also have its interior fitted with vertical reinforcement plates or other additional supports in flush with the column walls fig2 illustrates a number of different connecting members 22 for use in a building framework the connecting member 22 includes at least one horizontal coupling element 13 of a connecting member compatible with a coupling member 2 of a column and at least one vertical coupling element 16 of a connecting member compatible with a vertical coupling element 9 of a girder in case the building framework only comprises vertically positioned columns 1 and horizontally positioned girders 5 the connecting member 22 will be provided with no more than two horizontal coupling elements 13 of a connecting member and four vertical coupling elements 16 of a connecting member any intermediate configuration between the above extreme cases is possible for a connecting member it is natural that the girder systems may also.
