Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] The invention is attached Figure 1-9 As shown, a reinforced concrete hollow floor slab includes cast-in-place dense ribs 1, prefabricated side walls 2, prefabricated bottom slab 3, and cast-in-place roof 4. The hollow floor slab consists of prefabricated side walls 2, prefabricated bottom The dense rib 1 forms a cavity 5, and the prefabricated floor 3 has a groove 16 on the top, and the groove 16 is filled with a lightweight material 17. figure 1 It is a schematic diagram of filling the light material 17 in the groove 16 of the prefabricated bottom plate 3 .

[0021] There are longitudinal ribs or transverse ribs or both longitudinal ribs and transverse ribs in the groove 16 of the prefabricated floor 3, and the ribs 13 are covered with lightweight materials 17. In this way, the weight of the prefabricated floor 3 is reduced, and the prefabricated floor can also be...

Abstract

The invention discloses a reinforced concrete hollow floor slab and a construction method. The hollow floor slab comprises cast-in-situ dense ribs (1), a prefabricated side wall (2), a prefabricated bottom plate (3) and a cast-in-situ top plate (4). The top of the prefabricated bottom plate (3) is provided with a groove (16), and the inside of the groove (16) is filled with a light material (17). The construction method of the reinforced concrete hollow floor slab comprises the following steps of: erecting a template (11), binding ribbed reinforcing steel bars (12) and placing the prefabricated side wall (2); placing the prefabricated bottom plate (3) on a placement component (9), pouring concrete, disassembling the placement component (9) after the concrete reaches a certain strength and placing the prefabricated bottom plate (3) on a bottom projection (7) of the prefabricated side wall (2); and brushing mortar (15) below the prefabricated bottom plate (3) so as to form the whole hollow floor slab. The cast-in-situ concrete and the prefabricated parts of the hollow floor slab are combined to form a structural system which is stressed together, and the stress property and the integrity of the hollow floor slab are better. The inside of the prefabricated bottom plate is filled with the light material, and the floor slab has light weight, low manufacturing cost, good properties of heat preservation and heat insulation and convenient construction.

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. Some hollow slabs are assembled from multiple reinforced concrete prefabricated hollow components (patent application number 200420035588.6). Multiple prefabricated hollow components are arranged vertically and horizontally. On the bottom reinforced concrete, the gaps between the vertical and horizontal hollow members are filled with reinforced concrete to form dense ribs to form an assembled hollow floor slab. This kind of hollow floor slab needs to be poured with a bottom slab to form a hollow floor slab. The steel and concrete consume a lot of materials, and the weight increases. the cost of the floor. [0003] A reinforced concrete assembled floor slab (the ...
