Embodiment Construction
[0017] As shown in the accompanying drawings, the present invention is a reinforced concrete hollow floor slab, which includes a cast-in-place dense rib 1, a cast-in-place roof 2, and a prefabricated bottom plate 3, and is formed by a cast-in-place dense rib 1, a cast-in-place roof 2, and a prefabricated bottom plate 3 Cavity 4, the prefabricated bottom plate 3 is assembled by the top prefabricated block 7 and the bottom prefabricated block 8, and there are more than two gaps 6 on the bottom prefabricated block 8, wherein, the gap 6 on the upper part of the bottom prefabricated block 8 is used to place the top The prefabricated block 7 forms the prefabricated bottom plate 3, and the gap 6 at the bottom of the bottom prefabricated block 8 and the bottom protrusion of the cast-in-place dense rib 1 interlock. The hollow floor slab is composed of cast-in-place dense ribs 1, cast-in-place roof 2, and prefabricated bottom slab 3 to form a cavity 4, and the cast-in-place dense ribs 1,...

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 more than two notches (6). An upper notch of the bottom prefabricated block (8) is used for placing the top prefabricated block (7) to form the prefabricated soleplate (3). A lower notch of the bottom prefabricated block (8) is mutually engaged with a bottom projection (5) of the cast-in-situ multi-rib (1). 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 the 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...
