Description

A kind of prefabricated girder of laminated floor slab
Technical field
A kind of prefabricated girder of laminated floor slab is the utility model is related to, belongs to buildings in general constructing technology field.
Background technology
At present, it is known it is widely used industry with civil buildings floor construction, essentially cast-in-place solid reinforced concrete slab and Two kinds of precast hollow slab, using the former building, the rate of utilization of strength of its sound isolating and heat insulating performance difference and reinforced concrete is low, using the latter Building, its structural integrity difference is unfavorable for antidetonation, and handling workload is big.
With great attention of the building trade to energy-conserving and environment-protective, it is desirable to Development of Green Building, reduce building energy consumption conscientiously, go out Show various hollow brick laminated floor slabs, the laminated floor slab used at present, be made up of porous brick and cast-in-situ floor, or first cast-in-place girder Cast-in-situ floor again, work progress need the small beam steel of the artificial colligation in scene, and labor intensive work efficiency, colligation quality is uneven, colligation The small beam steel of shaping is rigidly poor, is easily deformed;Each small beam steel is both needed to set up bed die support, then with vertical flitch branch Support, timber consumption are big;During integral cast-in-situ, the mobility of concrete slurry is limited to, sky easily occurs in the end for forming girder shape Gap or voids and pits, influence the load-bearing of floor;And the complicated construction technique of whole building floor, enforcement difficulty is big, long in time limit, needs Substantial amounts of support shuttering, bed die and the support of vertical flitch are laid, safety hazards be present.
Utility model content
For the above-mentioned deficiency of prior art, the technical problems to be solved in the utility model is to provide a kind of laminated floor slab Prefabricated girder, to avoid floor integral construction from laying a large amount of support shutterings, complex process, enforcement difficulty is big, and small beam steel shows Time-consuming for the artificial colligation in field, and uniformity is poor, and rigidity is poor, and cast-in-place girder has the problem of space.
In order to solve the above technical problems, the utility model adopts the following technical scheme that:
A kind of prefabricated girder of laminated floor slab, the prefabricated girder are reinforced concrete structure, including the small beam body of concrete, Small beam steel, the small beam steel part are embedded in the concrete girder body to form embedded bar, embedded bar and institute State the overall structure that the small beam body of concrete is combined into armored concrete;The small beam steel part is from the small beam body of the concrete Side is stretched out to form top reserved steel bar, and top reserved steel bar is used to connect the reinforced mesh in floor and connects cast-in-place coagulation Soil;The small beam steel part is stretched out to form both ends reserved steel bar, both ends reserved steel bar from the small beam body both ends of the concrete For being overlapped with crossbeam;Two sides of the small beam body upper surface of concrete form building respectively between the top reserved steel bar Plate brick faying surface, contain the embedded bar in the concrete girder body below the floor brick faying surface.
Above-mentioned technical proposal is further improved, the small beam steel is triangular truss structure, including three are in isosceles triangle The truss supervisor for be arrangeding in parallel and being arranged along concrete girder body length direction, some abdomens being connected to two-by-two between truss supervisor Bar.
Further, the small beam body of the concrete is rectangular shape, and two truss supervisor of the small beam steel is pre-buried In the concrete girder body, a truss supervisor is reserved in above the small beam body of the concrete, and the two of three truss supervisors End exceeds the both ends of the small beam body of the concrete, is reserved in outer.
Further, some web members, which are welded and fixed, is connected between three truss supervisor.
In use, prefabricated girder is erected between crossbeam, supported by the vertical support bar for being supported on lower first floor face, nothing Small beam bottom board need to be set up again;Floor brick is laid between adjacent prefabricated girder by prefabricated girder as support frame.
Compared with prior art, the utility model has the advantages that:
1st, this prefabricated girder compares the girder of cast-in-place construction, and bed die, prefabricated girder need not be set up during floor slab construction Itself there is some strength and rigidity, a large amount of support shutterings, the frame of vertical support bar can be reduced as the support frame of floor brick If while improve working security;
2nd, the small beam body of precast concrete, avoid cast-in-place process and the problem of space and voids and pits occur, it is ensured that floor Load-bearing property;
3rd, small beam steel uses prefabricated triangle steel truss structure, compared to the structure of the artificial colligation in former scene, saves On-site construction time, the uniformity of manufacture is good, and quality is substantially improved, and whole structural stability is strong, and rigidity is good, is unlikely to deform;
4th, the laminated floor slab construction technology constructed using this prefabricated girder is simplified, and exploitativeness is strong, shortens the duration.
