Modular scaffold, consisting of - at least one elongated vertical paste comprising a metal tube or another hollow profile, into the end of which a hollow coupling profile is inserted, - of which the outer surface lies at least partly against the inner surface of the vertical post - which is connected to the vertical post by means of connectors, the connector interrupting the continuous surface of the vertical post and on each vertical post, at least one disk-shaped connection disk is pushed on, via a centre opening, which is located in its centre, and is fastened, and - the two large disk faces are in each case enclosed by the two legs of at least one approximately fork-shaped tubular cross-bar connection, which is connected to an approximately horizontally extending tubular crossbar, and - a key in each case and - is passed through one key opening in each case in the legs, as well as - through one edge opening in each case in the connection disks, - one coupling profile in each case is connected to a vertical post by means of two or more connectors, which are subdivided into - a first group (11 a) with the same distance in each case from the end of the vertical post and - a second group with the same distance in each case from the end of the vertical post, which is greater than in the case of the first group, characterised in that - a connection disk at least partly covers the second group (11 b) and - the end faces of the legs of the fork-shaped tubular cross-bar connection lie, outside the first group of connectors, on the vertical post. - at least one elongated vertical paste comprising a metal tube or another hollow profile, into the end of which a hollow coupling profile is inserted, - of which the outer surface lies at least partly against the inner surface of the vertical post - which is connected to the vertical post by means of connectors, the connector interrupting the continuous surface of the vertical post and on each vertical post, at least one disk-shaped connection disk is pushed on, via a centre opening, which is located in its centre, and is fastened, and - the two large disk faces are in each case enclosed by the two legs of at least one approximately fork-shaped tubular cross-bar connection, which is connected to an approximately horizontally extending tubular crossbar, and - a key in each case and - is passed through one key opening in each case in the legs, as well as - through one edge opening in each case in the connection disks, - is passed through one key opening in each case in the legs, as well as - through one edge opening in each case in the connection disks, - one coupling profile in each case is connected to a vertical post by means of two or more connectors, which are subdivided into - a first group (11 a) with the same distance in each case from the end of the vertical post and - a second group with the same distance in each case from the end of the vertical post, which is greater than in the case of the first group, characterised in that - a connection disk at least partly covers the second group (11 b) and - the end faces of the legs of the fork-shaped tubular cross-bar connection lie, outside the first group of connectors, on the vertical post. - a first group (11 a) with the same distance in each case from the end of the vertical post and - a second group with the same distance in each case from the end of the vertical post, which is greater than in the case of the first group, - a connection disk at least partly covers the second group (11 b) and - the end faces of the legs of the fork-shaped tubular cross-bar connection lie, outside the first group of connectors, on the vertical post.
