Problems solved by technology

This kind of hollow slab has the following disadvantages: 1. The amount of reinforced concrete in the bottom layer is large, which increases the construction time and construction difficulty; 2. The reinforced concrete in the bottom layer consumes a lot of steel and concrete, which increases the weight of the hollow slab.

Abstract

The present invention discloses a reinforced concrete hollow floor slab. It includes reinforced concrete prefaricated member and rib, the reinforced concrete prefabricated is hollow member, the outside wall of the described prefabricated member is equipped with bearing projection, two sides of the described rib are respectively equipped with supporting projection matched with said bearing projection. Several prefabricated members are arranged in crisscross mode and placed on the form, and the gap position of crisscross arranged prefabricated members can be filled up with reinforced concret so as to form ribs, the prefabricated members are supported by ribs, so that the invented hollow floor slab can be obtained.

Description

Technical field: [0001] The invention relates to the field of building construction, in particular to a reinforced concrete hollow floor slab. Background technique: [0002] Reinforced concrete cast-in-place hollow slabs consume less material than reinforced concrete solid slabs, and the slabs are lighter in weight. The existing reinforced concrete hollow slabs (patent application number 200420035588.6) adopt the technology of placing reinforced concrete hollow prefabricated components vertically and horizontally on the bottom reinforced concrete On the top, the gap between the vertical and horizontal hollow prefabricated components is filled with reinforced concrete to form dense ribs, forming a hollow floor slab. This hollow slab has the following deficiencies: 1, pouring the bottom reinforced concrete has a large supporting modulus, which increases the time and construction difficulty of construction; 2, pours the bottom reinforced concrete, which consumes a lot of steel ...
