In order to solve the above-mentioned technical problem, one of technical solution proposed by the present invention is:A kind of dress connected using self-locking With formula steel reinforced concrete composite floor, include the frame foundation formed by multiple hollow steel pipe columns, be fixed in frame foundation be horizontally disposed with H profile steel beam and the polylith that is arranged on H profile steel beam prefabricated reinforced concrete panel side by side, the H profile steel beam is by more Transverse beam and longitudinal beam are constituted, and every piece of prefabricated reinforced concrete panel is across on adjacent longitudinal beam;The longitudinal beam The top surface of top flange plate is connected with the floor that the length direction of beam along longitudinal direction extends, and the prefabricated reinforced concrete panel is equipped with Conduit that is downwardly open and matching with the floor is equipped with rubber and seals between the prefabricated reinforced concrete panel and longitudinal beam Material, the bottom surface of the prefabricated reinforced concrete panel, rubber envelope are expected, formation grouting is logical between the top flange plate and conduit of longitudinal beam Road, is filled with ungauged regions self-compacting high-strength concrete filler material in the grouting channel, on the prefabricated reinforced concrete panel Equipped with the stock inlet and grout outlet being connected to grouting channel.
Preferably, the conduit is in inverted trapezoidal, and concrete is filled in the hollow steel tubing string.
The improvement of one of above-mentioned technical proposal is:Between the prefabricated reinforced concrete panel, longitudinal beam and rubber envelope material It is to be glued.
Being further improved for one of above-mentioned technical proposal be:The floor is equipped with decorative pattern, and the floor is equipped with several Through-hole.
The further improvement of one of above-mentioned technical proposal is:Two pieces of adjacent prefabricated reinforced concrete panels are respectively equipped with It is directed towards and cooperate key teeth and keyway, is glued each other at the docking of the key teeth and keyway.
In order to solve the above-mentioned technical problem, technical solution proposed by the present invention second is that:A kind of assembled steel reinforced concrete combination building The installation method of plate, includes the following steps:
1)Hollow steel pipe column is installed and forms frame foundation, fixed H profile steel beam, the cloth above H profile steel beam are installed in frame foundation If floor;
2)Flexible strip rubber envelope material is bonded at the top flange plate edge of longitudinal beam;
3)The steel frame formed using hollow steel tubing string and H profile steel beam as platform, by lift installation with conduit and stock inlet, The prefabricated reinforced concrete panel of grout outlet, makes floor just be caught in conduit;Certainly using prefabricated reinforced concrete panel simultaneously The compression completely of rubber envelope material is ensured the leakproofness of grouting channel by body weight;
4)Ungauged regions self-compacting high-strength concrete filler material is subjected to pressure grouting by stock inlet, until each grout outlet flows out Stop grouting after continuous slurries, and rubber stopper closure is carried out to its grout outlet.
Being further improved for the two of above-mentioned technical proposal be:Adjacent two pieces of prefabricated reinforced concrete panels pass through preset key Tooth and keyway are attached, and are glued by epoxy resin in junction.
The advantageous effect that the present invention is brought is:
(1)The present invention mixes composite structure using H profile steel-and has given full play to steel construction and concrete respectively excellent performance, is reducing While depth of beam, the span of beam can be increased, thus conducive to the improvement interior space.
(2)The present invention uses assembled steel-concrete combined structure, and materials'use amount is few, and architecture quality lightens, and foundation cost becomes It is low, environmental protection more more energy efficient than traditional structure.
(3)The present invention using self-locking connection type, H profile steel beam and prefabricated reinforced concrete panel by floor and conduit into Row connection, and ungauged regions self-compacting high-strength concrete filler material is filled in the grouting channel formed between floor and conduit, Ungauged regions self-compacting high-strength concrete filler material forms an entirety in grouting channel, compared with prior art girder steel and pre-manufactured steel Reinforced concrete panel is only compared by peg connection, not only the faying face of ungauged regions self-compacting high-strength concrete filler material and floor Area it is big, to improve bonding strength height, and it is high to assemble construction efficiency.In addition, floor is located in grouting channel, pre- Under the complete encirclement of armored concrete panel processed, therefore faying face connector in the prior art can be efficiently solved(Peg)Corrosion And be difficult to quality control the problem of such as concrete cracking.
(4)Compared with traditional fabricated construction, in addition the present invention need not set up temporary support, can further improve Construction efficiency is assembled, construction quality is improved.
