Support structure for building engineering construction and assembled dust falling equipment

The invention belongs to the technical field of constructional engineering, and particularly relates to a support structure for constructional engineering construction and assembled dust falling equipment. The invention provides a building engineering construction support structure convenient to assemble and move and assembled dust falling equipment. The support structure for building engineering construction comprises a pedal vehicle and the like, and first square grooves are symmetrically formed in the pallet position of the rear portion of the pedal vehicle; the first square groove of the pedal vehicle is provided with the supporting mechanism for lifting the transverse plate, and the upper portion of the supporting mechanism is hinged to the rear side of the left side wall and the rear side of the right side wall of the transverse plate; and the protective guard is arranged at the top of the transverse plate. The whole support structure can be driven to move through the pedal vehicle, the transverse plate
