Zusammenfassung:	The invention discloses a foundation pit inner support without a stand column support used in a foundation pit, and aims to provide a foundation pit inner support which can bear the vertical load of a profile steel inner support beam so as to prevent the middle part of the profile steel inner support beam from bending downwards under the action of self weight; and stand column piles used for supporting the profile steel inner supporting beams in the foundation pit can be omitted, so that foundation pit inner supporting in the foundation pit is facilitated. The structural steel inner supporting beam is located in the enclosing purlin beam and used for supporting a foundation pit, the bracket device is used for supporting the structural steel inner supporting beam, the bracket device comprises two structural steel brackets located at the same height and a connecting longitudinal beam connecting the two structural steel brackets, and one structural steel bracket is located at one end of the structural steel inne
