DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-4. The utility model provides a technical solution: a support-free assembled integral high-rise reinforced concrete frame structure, including a cast-in-place concrete column 1;

A cast-in-place column cap 4 is provided on the top of the cast-in-place concrete column 1;

Two prefabricated main beams 2 are arranged on the top of the cast-in-place column cap 4, and the two prefabricated main beams 2 are located on the same straight line;

Prestressed double T-plates 3 are installed on one side of the two prefabricated main beams 2;

A cast-in-place laminate layer 6 is provided on the top of the prestressed double T-slab 3 .

As shown in FIG. 4 , a rubber support 5 is provided on the prefabricated main beam 2 , and the prestressed double T-plate 3 is installed on the rubber support 5 .

As shown in Figures 1 and 4, a laminated layer of steel bars is arranged on the top of the prestressed double T-slab 3, a surface bar is arranged on the top of the prefabricated main beam 2, and a laminated layer 6 is cast on the laminated layer of steel bars and the surface bar.

As shown in FIG. 2 , the prefabricated main beam 2 is an L-shaped structure, and the prestressed double T-plate 3 is arranged on the horizontal end of the prefabricated main beam 2 .

As shown in FIGS. 1-3 , the cast-in-place column cap 4 is a square structure, and two reinforcing plates are provided at the bottom of the prestressed double T plate 3 .

The working principle of the utility model is as follows: a plurality of cast-in-place frame columns 1 are arranged, column caps 4 are cast-in-place on the top of the cast-in-place frame columns 1, prefabricated main beams 2 are arranged at the four corners of the top of the cast-in-place column caps 4, prestressed double T-plates 3 are installed on the prefabricated main beams 2, and a cast-in-place composite layer 6 is arranged on the prestressed double T-plates 3 and the prefabricated main beams 2.
