Description
Technical Field
The utility model relates to a construction technical field specifically is an indoor girder steel of assembled steel construction house does not have exposed structure.
Background
The steel beams of the assembled steel structure house are exposed in the air under the common condition, or are packaged only through decoration and fitment, and cannot be isolated from the air, so that the assembled steel structure house is corrosion-resistant, fire-resistant and unfavorable for the structure, and the steel beams in the assembled steel structure house can cause corrosion and fire after being exposed in the air for a long time.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem to a there is not exposed structure of assembled steel construction house indoor girder steel is provided.
The utility model provides a problem, the technical scheme who adopts is:
the utility model provides an indoor girder steel of assembled steel construction house does not have exposed structure, including the girder steel, prefabricated superimposed sheet shelves on the bottom flange of girder steel, the round hole has been seted up to the web of girder steel, reinforcing bar on the prefabricated superimposed sheet passes the round hole of seting up on the girder steel web, placed in the net that prefabricated superimposed sheet upper rib beam reinforcing bar formed and filled the box, it has pour concrete layer to fill box upper end and fill between the box, the upper limb and the web of girder steel are wrapped up layer by the concrete, the bottom flange of girder steel is scribbled outward and is brushed anticorrosive paint layer and from interior to exterior has set gradually fireproof paint layer and plaster coat.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:
the problems of fire prevention and corrosion prevention of the indoor steel beam are solved, the working link including steel beam packaging in decoration is avoided, the later-stage maintenance problem caused by corrosion prevention in the later stage of the steel structure house is also avoided, and the cost is saved.

The specific implementation mode is as follows:
the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.
Referring to fig. 1, 2, 3, 4, 5, 6, 7 and 8, the assembled steel structure house indoor steel beam is of a non-exposed structure and comprises a steel beam 2 and a prefabricated composite slab 1, wherein the prefabricated composite slab 1 is placed on a lower flange of the steel beam 2, a web of the steel beam 2 is provided with a round hole, steel bars on the prefabricated composite slab 1 penetrate through the round hole formed in the web of the steel beam 2, a filling box body 3 is placed in a grid formed by the steel bars of an upper rib beam 4 of the prefabricated composite slab 1, a concrete layer 10 is poured between the upper end of the filling box body 3 and the filling box body, the upper flange and the web of the steel beam 2 are wrapped by the concrete layer 10, an anticorrosion paint layer is coated outside the lower flange of the steel beam 2, and a fireproof paint layer 8 and a plastering layer 9 are sequentially arranged from inside to outside.
The construction method of the structure comprises the following steps:
(1) mounting a steel beam 2;
(2) after the steel beam 2 is installed, selecting a corresponding prefabricated composite slab 1 according to a drawing, hoisting the prefabricated composite slab 1 in place, and placing the prefabricated composite slab 1 on the lower flange of the steel beam 2;
(3) binding iron steel bars 5 below the prefabricated laminated slab 1, and placing a filling box body 3 in a grid formed by the rib beam 4 according to a drawing;
(4) binding iron steel bars 6 on the prefabricated laminated slab 1;
(5) pouring a concrete layer 10, pouring the upper flange and the web plate of the steel beam 2 inside, and isolating the steel beam from the air;
(6) and (3) coating anticorrosive paint and a fireproof coating layer 8 on the lower flange of the steel beam 2, and finally coating an ash layer 9, and finally completing the isolation of the steel beam and the air to form an indoor steel beam non-exposed structure of the prefabricated steel structure house.
The utility model discloses a prefabricated superimposed sheet 1 sets up on girder steel 2 bottom flange, then through setting up the reinforcing bar, place packing box 3, it is isolated with the air to make girder steel 2 top flange and web such as concreting layer 10, girder steel 2 bottom flange is through applying paint anticorrosive paint with a brush, then spout fireproof coating layer 8, plaster layer 9 comes to be isolated with the air, the fire prevention of indoor girder steel 2 has been solved, the anticorrosive problem, work links including not only having avoided decorating fitment with girder steel 2 packing, the later stage maintenance problem that steel construction house later stage caused because of it is anticorrosive has still been avoided, the cost is saved.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent variations made by using the contents of the specification and the drawings are included in the scope of the present invention.
