Embodiment Construction
[0034] The present invention will be further described below in conjunction with accompanying drawing.
[0035] The SP prestressed hollow laminated slab combined floor beam-slab connection structure provided by the present invention mainly includes a SP prestressed hollow slab 1, a longitudinal reinforcement grid 4, a steel beam 5, a shear connector 6, Post-cast concrete layer 8, such as figure 1 , figure 2 , image 3 and Figure 4 shown.
[0036] Open the plate end groove 2 at the 1 / 4 core hole of the upper plate end of the SP prestressed hollow plate 1, and open the plate top hole 3 at the remaining core holes, and the opening position is aligned with the slot length, such as figure 1 , figure 2 and Figure 5 shown.
[0037] Set up the longitudinal steel grid frame 4 at the groove 2 of the plate end, and when it is a beam-slab connection at the side beam, it is spot welded and fixed with the steel beam 5 on site, such as figure 1 , figure 2 , image 3 and Figu...
