Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0018] Such as figure 1 and Figure 6 As shown, the laminated hollow floor of the honeycomb-hole profiled steel plate of the present invention is characterized in that: it comprises a base form when splicing a plurality of cell-hole profiled steel plates-concrete prefabricated base plate to form the floor construction, and the base form is provided with a concrete layer 4. Form a superimposed hollow slab; the cast-in-place concrete 4 should use fine stones as the coarse aggregate of the concrete, so as to make the pouring more compact.
[0019] Such as figure 2 As shown, the cell profiled steel plate-concrete prefabricated bottom plate includes a plurality of honeycomb hole profiled steel plates 1 with flanges on both sides, and the honeycomb hole profiled steel plate 1 in the honeycomb hole profiled steel plate-concrete prefabricated bottom plate T...

The invention provides a honeycomb pore profiled steel sheet overlapped hollow floor slab, and belongs to the field of buildings. The honeycomb pore profiled steel sheet overlapped hollow floor slab comprises a bottom formwork which is formed when a plurality of honeycomb pore profiled steel sheet-concrete prefabricated bottom plates are spliced to form a floor slab for construction. A concrete layer is arranged on the bottom formwork, and the overlapped hollow floor slab is formed. The honeycomb pore profiled steel sheet-concrete prefabricated bottom plates comprise a plurality of honeycomb pore profiled steel sheets with the two sides provided with flanges. The honeycomb pore profiled steel sheets are provided with a plurality of regular honeycomb-shaped holes. The honeycomb pore profiled steel sheets are spliced to be of a concave-convex structure. hollow dies are arranged between ribs of the concave-convex structure formed by splicing the honeycomb pore profiled steel sheets. Reinforced bars penetrate through the gaps of the hollow dies arranged on the concave-convex structure. The honeycomb pore profiled steel sheet overlapped hollow floor slab has the characteristics of low weight, high strength, reasonable structure and easy and convenient construction, and the hollow floor slab is filled with the prefabricated hollow dies so that the dead weight of the floor slab can be greatly lowered. The hollow dies is arranged at internals, and the horizontal reinforced bars are arranged, so that the bidirectional co-stressing characteristic of the floor slab is achieved, and stressing of the floor slab is more reasonable.
Description
technical field [0001] The invention relates to a hollow floor slab, and is especially suitable for a hollow-core floor slab laminated with honeycomb hole profiled steel plates used in the construction field. Background technique [0002] As one of the most suitable floor forms for industrial production, laminated floor slabs have the characteristics of quick construction, no need for formwork, no need for suspended ceilings, good integrity, and reasonable structural stress. However, the prefabricated floor of the traditional laminated floor is generally thicker to meet the needs of the floor with a larger span. This makes the prefabricated floor thicker and the weight of the laminated floor is also larger. Laminated hollow panels can save materials, reduce self-weight, and have better sound insulation effect, which has better economic benefits. At present, laminated hollow slabs are usually in the form of one-way slabs, and few can realize two-way slabs. Contents of the ...
