Abstract

The invention relates to a hollow floor filled by breathable boxes and a manufacturing method of the hollow floor and belongs to the field of general building structures. The hollow floor (1) comprises beam top iron pieces (2), beam bottom iron pieces (3), ribbed beam stirrups (4), plate top iron pieces (5), concrete (6) and breathable box combined bodies (7), wherein the beam top iron pieces, beam bottom iron pieces and ribbed beam stirrups form ribbed beams (8); the hollow floor plane is divided into multiple partitions (9) by two ribbed beams of which the directions are mutually orthogonal; the breathable boxes (10), steel wire meshes (11) and positioning separators (12) form the breathable box combined bodies (7); the breathable box combined body is mounted in each partition; the plate top iron pieces are assembled on the upper part of the breathable box combined body; the hollow floor is formed after concreting; and the thickness of the concrete on the lower part of the breathable box is more than or equal to 30mm. According to the hollow floor disclosed by the invention, raw material production and field floor construction are extremely convenient, and the hollow floor is large in span, light in weight and high in structural reliability, shock resistance and crack resistance.

Description

(1) Technical field [0001] The invention relates to a cast-in-situ concrete hollow floor structure, in particular to a hollow floor filled with a ventilating box and a manufacturing method thereof, belonging to the field of general building construction. (2) Background technology [0002] In the field of construction, with the increasing number of long-span concrete structures, more and more floor slabs adopt hollow-core floor structure technology. Replacing part of the concrete with lightweight filling materials will basically not affect the mechanical performance of the structure, but it can greatly reduce the self-weight of the structure. According to the current "Technical Regulations for Cast-in-situ Concrete Hollow Floors" JGJ / T268-2012, according to the different filling methods of filling materials, it can be divided into hollow slabs with built-in filling bodies, hollow slabs with single-sided exposed filling bodies and hollow slabs with double-sided exposed filling...
