Abstract
The utility model relates to a reinforced concrete hollow floor slab which comprises reinforced concrete prefabricated components and a dense rib, wherein, each of the reinforced concrete prefabricated components is a hollow component; stress convex blocks are arranged on the outer side walls of the prefabricated components; supporting convex blocks which are matched with the stress convex blocks are arranged on both sides of the dense rib; a plurality of prefabricated components are vertically and horizontally arranged on a mould slab; gaps of the prefabricated components in vertical and horizontal arrangement are filled with reinforced concrete so as to become the dense rib, and the prefabricated components are supported by the dense rib. Thus, a hollow floor slab can be formed. During construction, only the mould slab of the dense rib needs to be supported, and the mould slab of the whole floor slab does not need to be supported; thus, the mould supporting quantity is small, the reinforced concrete assembled on the bottom layer and the top layer is canceled; thereby, the consumption of the steel reinforcement and the concrete is small, and the weight of the floor slab is light, the difficulty of the construction is decreased, and the construction time is saved.
Description
Technical field:
The utility model relates to the realm of building construction, specifically refers to a kind of reinforced concrete hollow floor.
Background technology:
Reinforced concrete cast-in-situ hollow floor plate than steel concrete solid floor feed consumption lack, floor is in light weight, the technology that existing reinforced concrete hollow floor (number of patent application 200420035588.6) adopts is with hollow prefabricated steel bar reinforced concrete, arrange in length and breadth and be placed on the bottom layer of the reinforcing steel concrete, filling out with steel concrete at the hollow prefabricated gap location of arranging in length and breadth becomes close rib, forms cassette ceiling.This cassette ceiling has following deficiency: 1, and building the bottom layer of the reinforcing steel concrete, to prop up modulus big, increased the time and the difficulty of construction of construction; 2, build the bottom layer of the reinforcing steel concrete, reinforcing bar, concrete feed consumption are many, have increased the weight of cassette ceiling.
Summary of the invention:
The purpose of this utility model is to provide a kind of reinforcing bar, the concrete feed consumption is few, floor is in light weight, reduces a modulus, reduces difficulty of construction, saves the reinforced concrete hollow floor of engineering time.
The purpose of this utility model is achieved like this, this reinforced concrete hollow floor, comprise precast member for reinforcing bar concrete, close rib, precast member for reinforcing bar concrete is a hollow unit, described prefabricated units lateral wall is provided with stressed projection, described close rib both sides are provided with the supporting lug that is complementary with stressed projection, a plurality of prefabricated units are arranged in length and breadth and are placed on the template, filling out with steel concrete at the gap location of arranging prefabricated units in length and breadth becomes close rib, prefabricated units are supported by close rib, form cassette ceiling.
Because the precast member for reinforcing bar concrete lateral wall is provided with stressed projection, described close rib both sides are provided with the supporting lug that is complementary with stressed projection, a plurality of prefabricated units are arranged in length and breadth and are placed on the template, filling out with steel concrete at the gap location of arranging prefabricated units in length and breadth becomes close rib, prefabricated units are supported by close rib, form cassette ceiling.Site operation, the template of a need Zhi Haomi rib, the template that need not prop up whole floor, prefabricated units are built on stilts to be bearing on the template, and a modulus is little, has saved and has built bottom and surfacing steel bar concrete, reinforcing bar, concrete feed consumption are few, and floor is in light weight, also reduce construction difficulty, save the engineering time.

The specific embodiment:
With reference to figure 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, this reinforced concrete hollow floor, comprise precast member for reinforcing bar concrete 3,11, close rib 2,4, precast member for reinforcing bar concrete 3 is the box-like hollow unit, precast member for reinforcing bar concrete 11 is the flute profile hollow unit, and described prefabricated units 3,11 lateral walls are provided with stressed projection 6, and described close rib 2,4 both sides are provided with the supporting lug 9 that is complementary with stressed projection 6.Site operation, set up crisscross template 1 earlier, a plurality of prefabricated units 3 or 11 are arranged built on stilts being bearing on the template 1 in length and breadth, spread reinforcing bar 10,5 in length and breadth at the gap location of arranging prefabricated units 3 or 11 in length and breadth, concreting forms close rib 2,4, stressed projection 6 is subjected to supporting lug 9 supportings of close in length and breadth rib 2,4, forms cassette ceiling.
The stress surface 7 of stressed projection 6 is horizontal plane both, and also inclined-plane, the bearing surface 8 of supporting lug 9 be horizontal plane both, and also inclined-plane is complementary with stress surface 7.Cover plate 14 can be added a cover on the top or bottom space 13 of box-like hollow unit 3, flute profile hollow unit 11.
Precast member for reinforcing bar concrete 3 or 11 lamina tectis 14 are provided with connecting reinforcement 12, form close rib 2,4 in gap location and reinforcing bar 10,5, cast-in-situ concrete in length and breadth, make close rib 2,4 and prefabricated units 3,11 become integral body, increase cassette ceiling globality and crack resistance.
With reference to Figure 10, Figure 11, when stressed projection 6 is whole prefabricated units sidewalls, stressed inclined-plane 7 is exactly whole prefabricated units lateral wall.
