Technical Field
The invention relates to the technical field of buildings, in particular to a foamed light soil sandwich floor system.
Background
The floor slab in industrial and civil buildings is a bending member, the concrete in the compression area bears pressure, the steel bar in the tension area bears tension, and the stress near the neutral axis of the floor slab is very small, so in recent years, in order to save the concrete consumption and reduce the dead weight of the floor slab, the concrete near the neutral axis is drawn out to form a cavity, and a concrete rib connecting an upper layer plate and a lower layer plate is left to form a hollow floor slab. The hollow floor not only reduces the dead weight of 40-60% of the floor slab, but also keeps the rigidity of 80-90% of the floor slab, however, the hollow floor is provided with a cavity which is not beneficial to the load transmission of an upper plate, so that the upper plate still needs more tension steel bars to ensure that the load of the upper plate is transmitted to a concrete rib and then to a lower plate, in addition, the lower plate of the hollow floor is thinner and is not beneficial to the installation of fasteners such as expansion bolts and the like, and the part of the floor slab, which is not a ribbed plate, is not suitable for the installation position of a suspended ceiling or large-scale lamp decoration, thus the prior art still has certain defects.

Examples
As shown in fig. 1, a foamed light-weight soil sandwich floor includes:
an upper plate 3;
a lower laminate 1;
the upper plate 3 and the lower plate 1 are parallel and arranged at intervals;
a plurality of rib plates 4 are arranged between the upper plate 3 and the lower plate 1, one ends of the rib plates 4 are connected with the upper plate 3, and the other ends of the rib plates 4 are connected with the lower plate 1;
the upper plate 3, the lower plate 1 and the plurality of rib plates 4 are enclosed to form a cavity 6, and the cavity 6 is filled with foam light soil 2. The load of the upper plate 3 of the floor can be vertically transmitted to the lower plate 1 through the foam lightweight soil 2, the whole stress of the floor is stable, the thicknesses of the upper plate 3 and the lower plate 1 can be optimized, the configuration amount of tensile steel bars can be reduced, the foam lightweight soil 2 is foam cement lightweight soil prepared from cement paste and a special foaming agent for cement, the volume weight of the foam cement lightweight soil is 1/5-1/8 of concrete, the using amount of the concrete can be reduced, the self weight of the floor is reduced, the foam lightweight soil 2 is filled in the cavity 6, and the installation of a suspended ceiling or large-scale lamp decoration is not influenced. The invention adopts foam light soil 2 to replace a cavity 6 of a hollow floor system to form a sandwich structure.
The invention has two construction schemes of sandwich floor systems, which are as follows:
the first construction scheme is as follows: firstly, installing a template and a reinforcing steel bar of a lower layer plate 1 of a floor slab and a template and a reinforcing steel bar of a ribbed plate 4, then performing concrete pouring on the lower layer plate 1 and the ribbed plate 4, and then casting foam light soil 2 in a cast-in-place mode in a cavity 6; and pouring the upper plate 3 after the concrete of the lower plate 1 and the foamed lightweight soil 2 are initially set, and finally forming the floor with the sandwich structure.
The second construction scheme is as follows: firstly, prefabricating a foam prefabricated core block from foam lightweight soil 2 or an air-entrapping building block material in a prefabricated field or a factory building, firstly installing a lower layer plate 1 and reinforcing steel bars of a floor slab when in use, then placing the foam prefabricated core block on a reinforcing steel bar net of the lower layer plate 1, fixing the foam prefabricated core block through the reinforcing steel bars of a rib plate 4 and the reinforcing steel bars of the lower layer plate 1, arranging anti-floating reinforcing steel bars, and then integrally pouring the floor slab to finally form the floor slab with a sandwich structure.
The shortcoming of "hollow superstructure" can all be overcome to above-mentioned scheme, if the installation pipeline, the use scheme directly lay the pipeline for a moment can, during use scheme two, because "foam prefabricated core piece" is easily moulding, process easily, can be at will trompil, fluting on "foam prefabricated core piece", because hole, groove are less, and is very little to the gravity influence of floor, need not the repair. In addition, after the cavity 6 is filled, the floor slab cannot form a resonance cavity effect, the foam light soil 2 can absorb a large amount of noise, and the sound insulation effect is even better than that of the cavity 6.
As shown in fig. 1, in order to enhance the connection strength between the upper plate 3 and the rib plate 4, in the present embodiment, a rib plate reinforcing bar 7 is disposed between the upper plate 3 and the rib plate 4. In order to enhance the connection strength of the lower plate 1 and the ribbed plate 4, ribbed plate steel bars 7 are arranged between the lower plate 1 and the ribbed plate 4. In addition, a reinforcing steel bar 5 for reinforcing the connection strength between the upper plate 3 and the foam light soil 2 is arranged between the upper plate 3 and the foam light soil 2 in the cavity 6. And a reinforcing steel bar 5 for reinforcing the connection strength of the lower plate 1 and the foam light soil 2 is arranged between the lower plate 1 and the foam light soil 2 in the cavity 6. And the concrete upper and lower floor slabs and the foamed light soil 2 core are connected by adding steel bars, so that the integrity of the sandwich floor slab is further improved.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
