Embodiment Construction

[0019] As shown in the accompanying drawings, the present invention is a reinforced concrete hollow floor slab, which includes cast-in-place dense ribs 1 , cast-in-place roof 2 , and prefabricated bottom slab 3 . The present invention is characterized in that: the prefabricated bottom plate 3 is assembled from a top prefabricated block 7 and a bottom prefabricated block 8 . The prefabricated bottom plate 3 formed by the top prefabricated block 7 and the bottom prefabricated block 8 has a cavity inside, which can reduce the amount of reinforced concrete and reduce the weight. The prefabricated bottom plate 3 can be mechanized and the construction speed is fast.

[0020] The present invention is also characterized in that there are ribs 9 on the bottom prefabricated block 8, and the ribs 9 on the bottom prefabricated block 8 can be longitudinal ribs, transverse ribs or criss-cross ribs, which effectively improves the strength and rigidity of the prefabricated floor 3.

Abstract

The invention discloses a reinforced concrete hollow floor slab, which comprises a cast-in-situ multi-rib (1), a cast-in-situ crest slab (2) and a prefabricated soleplate (3). The prefabricated soleplate (3) is formed by joining a top prefabricated block (7) and a bottom prefabricated block (8). The bottom prefabricated block (8) is provided with a rib (9) or stuffing (10). The bottom prefabricated block (8) is provided with two or more notches (6). When producing the hollow floor slab, the cast-in-situ multi-rib (1) and the cast-in-situ crest slab (2) are firstly poured, and then a reinforcement fabric (11) and the prefabricated soleplate (3) are arranged on a bottom projection (5) of the cast-in-situ multi-rib (1) or on a projection (5) which is coated with mortar (12); the cast-in-situ multi-rib (1), the cast-in-situ crest slab (2) and the prefabricated soleplate (3) form a cavity (4); and the mortar (12) is painted below the prefabricated soleplate (3) to form an integral hollow floor slab. The hollow floor slab has good integrity, large rigidness, high bearing capacity, long service life and simple construction procedure.

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 gaps between the vertical and horizontal hollow prefabricated components are filled with reinforced concrete to form dense ribs to form a hollow floor slab. This kind of hollow floor slab has the following disadvantages: steel bars and concrete consume a lot of materials, which increases the cost of the floor slab, and the integrity of the floor slab is not good; moreover, the box-shaped hollow member is large in siz...
