The support structure includes: a plurality of rows of structural columns arranged in the foundation pit and vertically opposite to a plurality of basement structural beams; the structural columns penetrate each basement floor slab in the vertical direction and are fixed to the bottom of the basement top slab at the ground elevation, and each row of structural columns is connected to the corresponding basement structural beam.

[0004] A further improvement of the utility model is that it also includes two columns of retaining columns arranged at the head and tail ends of a plurality of rows of the structural columns. Each column includes a plurality of retaining columns, and a plurality of the retaining columns are vertically opposite to a plurality of rows of structural columns one by one; the retaining columns penetrate each basement structural floor slab in the vertical direction and are fixed to the bottom of the basement top slab at the ground elevation, and the two columns of retaining columns respectively connect the two ends of the basement structural beam.

[0005] A further improvement of the utility model is that the embedding depth of the retaining column is greater than the embedding depth of the structural column.

[0006] A further improvement of the utility model is that the structural column includes a lattice column inside and a frame column sleeved outside the lattice column to reinforce the lattice column, and the basement structural beam is connected to the frame column.

[0007] A further improvement of the utility model is that stud nails are nailed on the outer surface of the lattice column, and the frame column is connected to the outside of the lattice column through the stud nails.

[0008] The support structure of the utility model in which a basement structural column serves as a foundation pit support directly constructs a structural column at the position of the basement structural column and uses the structural column as a support column of the foundation pit at the same time to achieve the effect of dual use of one column. When constructing the basement, there is no need to remove the foundation pit support. The structural column can be directly reinforced and used as a support column of the basement. By using this support structure, the procedures of basement construction are effectively reduced and the construction progress is accelerated. Description of the Drawings
