A reinforcing method for a steel beam (10) embodiment having a steel profile (20) comprising a lower head (23) and an upper head (21) which is substantially parallel to said lower head (23), characterized by comprising the steps of:
- a) Connecting embedded studs (232) under the lower head (23) of the steel profile (20),
- b) Positioning the fixture (41) and cables (42) inside a mold system (30),
- c) Positioning the steel profile (20) on the mold system (30) such that the embedded studs (232) are placed into said fixture (41),
- d) Applying pre-tensioning process to said cables (42) by means of pre-tensioning apparatus (60),
- e) Fixing the tensions and positions of said cables (42) and applying lower reinforcing concrete (40) to a concrete chamber (312) provided in the mold system (30),
- f) Removing the pre-tensioning apparatus (60) and releasing the cables (42),
- g) Transferring the tensioning forces, existing in the fixed cables (42) and in the lower reinforcing concrete (40), to the steel beam (10) through the embedded studs (232).
