Abstract
The present invention discloses a reinforced concrete hollow floor plate which comprises a plurality of reinforced concrete precast members and dense ribs, wherein the reinforced concrete precast members are hollow, and the outer side walls of each precast member are provided with stress lugs; both sides of each rib are provided with supporting lugs matched with the stress lugs; the precast members are vertically and horizontally arranged on a template; the gaps among the precast members vertically and horizontally provided are filled with reinforced concrete to form the dense ribs; the precast members are supported by the dense ribs to form the hollow floor plate; the opening of each precast member is provided with a box-shaped hollow cover plate. As the opening of each precast member is provided with the box-shaped hollow cover plate, the weight of the floor plate does not increase if the thickness of the cover plate does not increase; the area of the outer side wall of each cover plate is greatly enlarged, and the surface of each precast member, which is in contact with the cast-in-place concrete is enlarged; therefore, water on the floor plate is hard to leak into the inner cavities of the precast members, and water does not accumulate in the inner cavities of the precast members.
Description
Technical field:
The present invention relates to the realm of building construction, specifically refer 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 object of the present invention is to provide the water on a kind of floor to be difficult for to hollow prefabricated inner chamber seepage, the prefabricated units inner chamber can ponding, does not increase the reinforced concrete hollow floor of floor weight again.
The present invention seeks to realize 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, hollow prefabricated opening part is stamped the steel concrete cover plate, arranging prefabricated units in length and breadth, the gap location of cover plate is filled out with steel concrete becomes close rib, prefabricated units, cover plate is supported by close rib, the steel concrete cover plate is the hollow cover plate of box-like on the described prefabricated units opening, and the hollow cover plate lateral wall of box-like is provided with connecting reinforcement.
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, water on the floor is difficult for to hollow prefabricated inner chamber seepage, the prefabricated units inner chamber can ponding, connecting reinforcement is at gap location and integral body is formed in reinforcing bar, cast-in-situ concrete in length and breadth, make the hollow cover plate of close rib and box-like become integral body, increase cassette ceiling globality and crack resistance, 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 invention 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 present invention can be widely used in house, bridge construction.
