The invention relates to the technical field of steel structure construction, and discloses a cross-layer steel truss inverted hanging type construction method which comprises the following steps: S1, construction of steel frames at the two ends of a roof cross-layer truss; s2, a roof cross-layer truss is hoisted; s3, the davit is installed; s4, hoisting of a lower-layer floor truss; and S5, secondary steel member construction. According to the construction method, the roof cross-layer truss is hoisted firstly, then the floor truss on the lower layer is hoisted, an inverted hoisting method is adopted, a traditional construction method from bottom to top is eradicated, and the situation that when the steel structure on the upper layer is hoisted, a temporary support needs to penetrate through the formed steel structure on the lower layer, and consequently construction is difficult is avoided. When the davit is installed, the davit bears axial tension, a lateral stable support does not need to be additionally a
