Fig. Ι a partial view of a door frame.,

Fig. 2 shows a section through the box profile 3 along the line b of Fig. 1, Fig. 3 shows a section through the box section 3 along the line / Fig. 1,

Fig. 4 a section through the corner connection along the line «of Fig. I,

Fig. 5 a section along the line c of Fig. I,

Fig. 6 shows a section through the box section 1 along the lines in Fig. 1 and Fig. 7 shows a section through the box section 2 along the line d in Fig. 1.

In particular: 1 means a box section with one-sided, open guide rail, 2 a box profile with both-sided open guide rail, 3 sin box profile with one open and one closed guide rail, 4 the stepped closed guide bar of the box section 3, 5 the clear width of the Box profiles 1, 2, 3, 6 the open guide strips of box profiles 1, 2, 3, 7 infill insert, S infill window, 9 infill sheet formwork.
