[0047] Refer to the instructions attached figure 1 Attached Picture 9 The prestressed concrete composite slab with steel truss and the manufacturing method of the present invention will be described in detail below.
[0048] The pre-stressed concrete laminated slab with steel truss of the present invention includes a prefabricated base plate 1, transverse steel bars 3 and a laminated layer 4. The prefabricated base plate 1 includes a plurality of pieces, and each prefabricated base plate 1 extends along the length direction. The two sides of the prefabricated bottom plate are inclined surfaces 11, and a wedge-shaped seam 2 is formed between adjacent prefabricated bottom plates 1. The wedge-shaped joint 2 is filled with high-strength grouting material to the upper surface 10 of the prefabricated bottom plate. The interior of the prefabricated bottom plate 1 is arranged longitudinally along the length The pre-stressed steel bars 5 are arranged in the width direction and the horizo...
