Description

Technical Field

[0001] This disclosure relates to the field of building technology, and in particular to a honeycomb-shaped reinforced concrete structural floor slab. Background Technology

[0002] Honeycomb structures not only possess high specific strength and specific stiffness, but are also lightweight and have excellent energy absorption properties, making them widely used in the manufacture of shells for aerospace, aircraft, and trains. Traditional honeycomb structures primarily rely on longitudinal load-bearing capacity, with relatively weak lateral load-bearing capacity, which aligns with the stress characteristics of floor slab structures.

[0003] Currently, most large-span hollow cavity floor slabs on the market adopt vertically arranged rib beams and are filled with lightweight cubes. This is because current floor slab calculation methods calculate the X and Y vertical directions separately. However, for one-way slabs, the main direction is calculated based on stress, while the non-main directions are for structural reinforcement. Therefore, for one-way slabs, especially large-span one-way slabs, the traditional floor slab construction method results in excessive self-weight and increases construction costs.

The outer edge of the isosceles trapezoidal top plate is coplanar with the outer edge of the honeycomb ribs, and the isosceles trapezoidal top plate is located above the honeycomb ribs.

[0012] The third honeycomb configuration consists of a pentagonal top plate, honeycomb ribs, and honeycomb cavities.
