Description

A composite hollow floor slab with honeycomb hole profiled steel plate

technical field

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

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 invention

Aiming at the deficiencies of the above-mentioned technologies, a hollow-core floor slab laminated with honeycomb hole profiled steel plates is provided with simple structure, light weight, no bottom form, fast and convenient construction, two-way force, reasonable structure and good integrity.

In order to achieve the above object, the honeycomb hole profiled steel plate laminated hollow floor slab of the present invention comprises a bottom form when the floor is constructed by splicing a plurality of honeycomb hole profiled steel plates-concrete prefabricated floor, and a concrete layer is poured on the bottom form to form laminated hollow panels;

The cell profiled steel plate-concrete prefabricated bottom plate includes a plurality of honeycomb hole profiled steel plates with flanges on both sides, and a plurality of hollowed out honeycomb hole profiled steel plates are arranged on the honeycomb hole profiled steel plate, and the honeycomb hole profiled steel plate It is a corrugated thin steel plate with a cross-section bent into the shape of "Ji". Multiple honeycomb-hole profiled steel plates are spliced through the flanges on both sides to form a concave-convex structure with the same interval. There are multiple hollow molds, and there are gaps between multiple hollow molds arranged longitudinally in the same rib. The hollows in the gaps are provided with steel bars that pass through the concave-convex structure of the honeycomb hole profiled steel plate transversely, and the steel bars are close to the honeycomb hole. The concave-convex surface on one side of the steel plate is poured into the concrete slab.

The hollow form is an open hollow box or a lightweight filling block, and the open surface of the open hollow box is close to the concrete floor when it is arranged; The lower flange of the honeycomb profiled steel plate is assembled by buckle or iron wire; the hollow hole pattern of the honeycomb arrangement of the honeycomb profiled steel plate adopts hexagonal holes, Round holes or other hole shapes; the steel bars pass through the hollows arranged in the honeycomb arrangement of the honeycomb-hole profiled steel plate, and the ribs and the honeycomb-hole profiled steel plate are fixed to each other by iron wires.

Beneficial effects: The hollow floor slabs laminated with honeycomb-hole profiled steel plates use the honeycomb-hole profiled steel plates themselves with honeycomb hollows, which provide sufficient rigidity and reduce weight under the premise of ensuring strength. The honeycomb-hole profiled steel plates are formed by splicing The concave-convex structure is integrated with the concrete slab, and the hollow formwork is set between the ribs of the honeycomb-hole profiled steel plate to further reduce the weight. The arrangement of the hollow formwork at intervals and the arrangement of transverse steel bars can realize the two-way joint force of the floor, making the force of the floor structure more reasonable. .

The invention makes full use of the combination effect of the steel plate and concrete, and sets hollow molds between each rib of the profiled steel plate, so that the upper and lower flanges and webs of the profiled steel plate are wrapped by concrete, forming a more reasonable combination form.
