The new construction projects of the construction industry at present tend to large-space, beamless and column-less structures more and more, namely a cast-in-place beamless hollow floor structure system, which is characterized in that a plurality of box bodies horizontally uniformly distributed at intervals are used for forming a gap grid for in-place concrete pouring to form a hidden beam system for bearing external load, so that the effect of occupying space by exposing an original primary beam and a secondary beam under a floor is avoided, raw materials are saved, the use space is enlarged, the construction period is accelerated, and the cost is reduced.

When the built-in box body of the traditional cast-in-place beamless hollow floor slab is constructed, the built-in box body is required to be installed in the middle of reinforced concrete of the hollow floor slab, so that after the bottom steel bars are laid during construction, the built-in box body is arranged according to drawing requirements, the box body is installed and fixed, cushion blocks are arranged on four feet of each box body simultaneously, and each built-in box body is fixedly bound with the bottom steel bars by iron wires so as to prevent the built-in box body from floating upwards or horizontally displacing to influence the construction quality when concrete construction is poured.

Disclosure of Invention

The utility model aims to provide a multi-support box body of a cast-in-place hollow floor slab, which is used for casting the cast-in-place concrete hollow floor slab in site construction.

The utility model aims to realize the multi-pillar box body of the cast-in-place hollow floor slab, which comprises a box body A, wherein the box body A is of a cubic groove structure, at least two pillars vertical to the bottom surface are uniformly distributed in the box body A, a reinforcing rib in a shape like a Chinese character 'mi' is processed on the bottom surface of the box body A, vertical reinforcing ribs are processed on four side surfaces of the box body A, the upper end of the side surface of the box body A is provided with a circumferential fixed edge, and supporting leg mounting holes are vertically processed at four vertex angles of the box body A.

The multi-post box further comprises an upper cover plate E which is combined with the box bodies A, B, C with different heights respectively to form box structures in various forms when in use.

Preferably, steel bar supporting legs are inserted into the supporting leg mounting holes, and the height of each box body from the template is adjusted by adjusting the depth of the steel bar supporting legs inserted into the supporting leg mounting holes.

The utility model has the following advantages and positive effects:

1. the utility model is used for cast-in-place concrete hollow floor slabs in large quantity, reduces the use of sub beams and columns, reduces the construction cost of buildings and increases the use space on the basis of saving materials, and leads the stress of the structure to be more reasonable.

2. The box body structure is simple and reasonable, can be uniformly arranged according to a drawing during construction, does not need a cushion block or box body positioning binding, does not generate the phenomena of box body floating and horizontal movement, can form box body structures with various height size forms by utilizing the combination among box bodies with different heights during construction according to requirements, can be mutually sleeved for convenient transportation, greatly increases the transportation quantity, can be assembled on site during construction, and has the advantages of low labor intensity, low cost, quick construction progress and easier quality control.
