Abstract
The utility model discloses a steel bar reinforced concrete hollow floor which comprises a reinforced concrete prefabricated component and a dense rib; the reinforced concrete prefabricated component is a hollow component; stress projections are provided on the outer side wall of the prefabricated component; supporting projections matching with the stress projections are provided on both sides of the dense rib; a plurality of prefabricated components which are vertically and horizontally arranged are positioned on a pattern slab; the gap of the prefabricated components which are vertically and horizontally is filled with reinforced concrete so as to become the dense rib; the prefabricated components are supported by the dense rib, which forms a hollow floor slab; a box shape hollow cover board is provided on the opening of the prefabricated component; because the box shape hollow cover board is provided on the opening of the prefabricated component, the thickness of the cover board can not increase, and the weight of the floor can not increase; but the area of the outer side wall of the cover board is increased, and a contact face contacting cast-in-place concrete is increase, so water on the floor can not easily leak into the inner cavity of the hollow prefabricated component, and the inner cavity of the prefabricated component can not accumulate water.
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, existing reinforced concrete hollow floor, the technology that adopts is to be provided with stressed projection at the hollow prefabricated steel bar reinforced concrete lateral wall, reinforced concrete ribbed 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.The user can cover the steel concrete cover plate or spread other panel as required at hollow prefabricated opening part, but this cassette ceiling has following deficiency: hollow prefabricated opening part covers the steel concrete cover plate, the sidewall of steel concrete cover plate is thin, to contact face little with the cast-in-situ concrete of building close rib, water on the floor passes through the slit easily to hollow prefabricated inner chamber seepage, as doing cover plate thick, sidewall area is a little bigger, has increased floor weight again; Hollow prefabricated opening part is directly spread other panel (as wood flooring), and the panel sidewall is also thin, and gapped between the adjacent panels, the water on the floor also easily to hollow prefabricated inner chamber seepage, causes hollow prefabricated inner cavity water accumulation.
Summary of the invention:
The purpose of this utility model is to provide the water on a kind of floor to be difficult for to hollow prefabricated inner chamber seepage, and the prefabricated units inner chamber can ponding, does not increase the reinforced concrete hollow floor of floor weight again.
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, the 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, and described prefabricated units opening is provided with the hollow cover plate of box-like.
The hollow cover plate lateral wall of described box-like is provided with the antiseep projection.
Because the prefabricated units opening is provided with the hollow cover plate of box-like, the thickness of cover plate does not increase, floor weight can not increase yet, but the lateral wall area of cover plate has increased much, to contact face big with cast-in-situ concrete, and the water on the floor is difficult for to hollow prefabricated inner chamber seepage, and the prefabricated units inner chamber can ponding, as being provided with the antiseep projection at the hollow cover plate lateral wall of box-like, antiseep better effects if then.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described

The specific embodiment:
With reference to figure 1---Figure 18, this reinforced concrete hollow floor, comprise precast member for reinforcing bar concrete 8, close rib 10,11 in length and breadth, precast member for reinforcing bar concrete 8 is a hollow unit, prefabricated units 8 lateral walls are provided with stressed projection 7, close rib 10,11 both sides are provided with the supporting lug that is complementary with stressed projection 7, a plurality of prefabricated units 8 are arranged in length and breadth and are placed on the template 12, the prefabricated units opening is provided with the hollow cover plate 3 of box-like, the hollow cover plate lateral wall 1 of box-like is provided with antiseep projection 6, the hollow cover plate 3 of box-like promptly can be square box, also can be the rectangle box.
Cover after 9 in back-up sand slurry is put down between the hollow cover plate 3 of prefabricated units 8 and box-like, filling out with steel concrete at the gap location of arranging the hollow cover plate 3 of prefabricated units 8 and box-like in length and breadth becomes close in length and breadth rib 10,11, the hollow cover plate 3 of prefabricated units 8 and box-like is subjected to close in length and breadth rib 10,11 supportings, forms cassette ceiling.
The lateral wall 1 of the hollow cover plate of box-like, the thickness of top board 4 do not increase, floor weight can not increase, but the area of the lateral wall 1 of cover plate has increased much, to contact face big with the cast-in-situ concrete of building close in length and breadth rib 10,11, water on the floor is difficult for to hollow prefabricated inner chamber 5 seepages, and prefabricated units inner chamber 5 can ponding, the antiseep projection 6 that hollow cover plate 3 lateral walls 1 of box-like are provided with, percolating water there is the stifled effect of resistance, also is subjected to the supporting of close rib 10,11 simultaneously.
The connecting reinforcement 2 that is provided with on the hollow cover plate lateral wall 1 of box-like, at gap location and reinforcing bar in length and breadth, integral body is formed in cast-in-situ concrete, makes close rib 10,11 and the hollow cover plate 3 of box-like become integral body, increase cassette ceiling globality and crack resistance.
The utility model can be widely used in house, bridge construction.
