The invention relates to the technical field of holographic projection, and discloses a combined truss for a holographic projection curtain wall. The combined truss comprises a truss body, an installation plate is fixedly installed on the front face of the truss body, a curtain roll is installed on the front face of the installation plate in a sliding mode, a projection screen is stretched out ofone side of the curtain roll, a pull column is fixedly installed at one end of the projection screen, and a transverse frame is fixedly installed in the middle of a truss stand column. According to the combined truss for the holographic projection curtain wall, the curtain roll is vertically arranged at one side of a truss; the projection screen is driven by rotation of wind-blowing fan blades todrive the belt to rotate, so that a pull column pulls the projection screen to be transversely unfolded; blowing of left and right wind directions to the projection screen is overcome; through holes are formed in a wood plate
