Description

Formwork-supporting-free self-insulation floor system with steel structure

Technical Field

The utility model belongs to the technical field of fabricated building floors, and particularly relates to a steel structure formwork-free self-insulation floor system.

Background

The steel structure building is a novel building system, and at present, the application of steel in high-rise buildings is mature day by day and gradually becomes a mainstream building process. The steel structure building has the following advantages: the construction time can be greatly saved, and the construction is not influenced by seasons; the using area of the residential space can be increased, and the construction waste and the environmental pollution are reduced; the building material can be repeatedly used, and the development of other novel building material industries is pulled; the shock resistance is good, the use is easy to modify, the flexibility and the convenience are realized, the comfort is brought to people, and the like, so that the shock resistance is more and more widely applied. One kind of floor on current steel construction is steel bar truss building carrier plate, but all uses the bottom steel sheet of steel bar truss building carrier plate as the template, welds profiled sheet on the roof beam during connection, or welds the peg on the roof beam, then concreting.

The defects of the technical scheme are as follows: firstly, the bottom steel plate of steel bar truss floor carrier plate can not be dismantled, can not reuse, has consumed a large amount of steel sheets. Secondly, the difficulty of decoration of owners is increased. Thirdly, the floor slab needs to be additionally provided with a heat insulation layer.

The second method is to support the steel structure, lay the floor support plate, fix the steel bar grid, and pour concrete.

The defects of the technical scheme are as follows: the floor needs to be additionally provided with a heat insulation layer.

The third way is to hoist the precast concrete floor slab to the steel beam and then install. For example, chinese patent No. CN106088432B discloses a floor slab splicing structure and a building formwork including the floor slab splicing structure. In the floor splicing structure, splicing sides of a first floor to be spliced and a second floor to be spliced are respectively erected on two sides of a first I-shaped steel lower flange; a first groove is formed in the first floor to be spliced from the top side to the splicing side of the first floor to be spliced, and a first connecting part extends from the body part of the first floor to be spliced into the first groove; a second groove is formed from the top side to the splicing side of the second floor slab to be spliced, and a second connecting part extends from the body part of the second floor slab to be spliced into the second groove; one end of the connecting rib is accommodated in the first groove, and the other end of the connecting rib penetrates through the web plate of the first I-shaped steel and is accommodated in the second groove; and pouring layers are formed in the first groove and the second groove.

The above prior art solutions have the following drawbacks: firstly, in the process of assembling the floor slab, the floor slab usually needs to be hoisted for installation, the scheme needs to insert the two adjacent side edges of the floor slab into the lower flanges of a pair of adjacent first I-beams, then slowly lower the other two side edges of the floor slab, and directly fall onto the upper flanges of the two corresponding second I-beams, the floor slab needs to be positioned at a plurality of adjusting positions in the air, the floor slab can be installed completely, and the installation process of the floor slab is slow. Secondly, the floor slab needs to be additionally provided with an insulating layer.

And fourthly, supporting the steel structure, hoisting the concrete composite slab, placing two ends of the concrete composite slab on the steel beam, and pouring concrete on the concrete composite slab to form the floor slab.

The defects of the technical scheme are that firstly, the concrete laminated slab has large area, heavy weight, high hoisting cost and time and labor consuming operation. Secondly, a special transportation channel for a large trailer needs to be arranged on the site, the turning radius needs to be large, a special bearing stockyard needs to be arranged, and a top plate of a ground warehouse needs to be specially designed in an enhanced mode. Thirdly, the floor slab needs to be additionally provided with a heat insulation layer.

Fourthly, more raw materials such as cement, reinforcing steel bars and the like are used.
