Embodiment Construction

[0012] The invention is attached Figure 1~5 As shown, a reinforced concrete hollow floor slab includes cast-in-place dense ribs 1, prefabricated side walls 2, prefabricated floor 3, and cast-in-place roof 4. There are holes 7 or gaps 13 at the bottom of the prefabricated side walls 2, and there are holes 7 or gaps 13. Support rib 6. figure 1 It is a schematic diagram of the construction of reinforced concrete hollow slabs. During construction, the hollow slab formwork 11 is first erected, the rib beam steel bars 12 are bound, and the prefabricated side walls 2 are placed between the rib beam steel bars 12. The upper part of the prefabricated side wall 2 has a shelf 9, and the hole at the bottom 7 or in the gap 13, the supporting ribs 6 are bound; the prefabricated bottom plate 3 is placed on the shelf 9, and concrete is poured between the vertically and horizontally arranged prefabricated side walls 2 and on the upper part of the prefabricated bottom plate 3. After the concre...

Abstract

The invention discloses a reinforced concrete hollow floor slab and a construction method. The hollow floor slab comprises a cast-in-situ multi-rib (1), a prefabricated side wall (2), a prefabricated soleplate (3) and a cast-in-situ crest slab (4). The bottom part of the prefabricated side wall (2) is provided with a hole or a notch (7), and a supporting rib (6) is arranged inside the hole or the notch (7). The construction method of the hollow floor slab comprises the following steps: erecting a hollow floor slab molding plate (11), binding a ribbed reinforced bar (12) and placing the prefabricated side wall (2); placing the prefabricated soleplate (3) on a holding piece (9), pouring the concrete, removing the holding piece (9) after the concrete reaches a given strength, and placing the prefabricated soleplate (3) on the supporting rib (6) on the bottom part of the prefabricated side wall; utilizing the prefabricated side wall (2), the prefabricated soleplate (3) and the cast-in-situ crest slab (4) to form a cavity (5), painting mortar (15) on the bottom of the prefabricated soleplate (3) to form an integral hollow floor slab. The hollow floor slab consists of cast-in-situ concrete and prefabricated components, so the floor slab has light weight and good integrity.

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] The patent with the publication number CN 1900449A discloses a reinforced concrete ribbed floor slab, in which a plurality of hollow prefabricated component frames are placed on the formwork, the prefabricated component covers are covered on the hollow component frames, and the gaps between the vertically and horizontally arranged prefabricated components are filled. The reinforced concrete is used as dense ribs to form a cast-in-place dense rib hollow floor slab. This kind of hollow floor slab all has the following disadvantages: steel bars and concrete consume a lot of material, and it is heavy, which increases the cost of the floor slab; the integrity and impermeability of the floor slab are not good. Invention content: [0003] The object of the present invention is to provide a reinforced concret...
