Abstract
One kind of profiled bar-concrete combined girder relates to a flyover componed of combination bridge , which comprises of the topper reinforced concrete block, the lower profiled bar girder and the cut-joint part between these. The character of the girder is that the mentioned cut-joint part comprises continuous wave-shaped reinforcing steel bar located on top of profiled bar girder. The single wave's shape is trapezia or the polygon approximated to trapezia. At the side of the profiled bar girder, all the top of trapezia joint to it, on the other hand the top stretch into the reinforced concrete. The cut-joint part of the girder can be directly made to continuous structure by the whole round steel. The part is made and installed extremely easily and has the biggest strength combined with the reinforced concrete block, the stronger cut-resistant behavior and can also strengthen the intensity of the reinforced concrete, under the same cut-resistant intensity, the whole cost of the combination girder is much lower than the single cut-joint profiled bar-concrete combination girder as well.
Description
Technical field:
The present invention relates to a kind of spanning member of combined bridge, particularly a kind of shaped steel-concrete combination beam.
Background technology:
Shaped steel-concrete combination beam as combined bridge top (spanning) member has obtained application widely owing to have advantages such as own wt is light, construction costs is low, structure stress is reasonable, and becomes the principal mode of the structure of domestic and international combined bridge spanning gradually.Shaped steel-concrete combination beam is by section steel beam, armored concrete slab, and the shearing connecting piece that is positioned between the two constitutes, the shearing connecting piece of existing shaped steel-concrete combination beam all adopts monomer-type, mainly contain socket cap weldering nail connector, the channel-section steel connector, forms such as bent-up bar connector are (referring to Fig. 6～Fig. 8), in order to guarantee the intensity of shaped steel-concrete combination beam, every meter long Liang Shangxu arranges tens, dozens or even hundreds of shearing connecting piece, and must be according to the relevant building operations standard of country, spacing between the strict control shearing connecting piece, installation direction etc., thereby expended great amount of manpower, in man-hour, the cost and the difficulty of construction of compound beam have been increased.
Summary of the invention:
The technical problem to be solved in the present invention is: existing shaped steel-concrete combination beam adopts the existing shearing connecting piece of monomer-type shearing connecting piece various, consuming time, consumption power, the cost of compound beam and the problem of difficulty of construction have been increased, the shearing connecting piece that a kind of employing is provided is the shaped steel-concrete combination beam of continuous structure, the making of the shearing connecting piece of the continuous structure of this compound beam and construction and installation are very easy, the adhesion of itself and concrete slab is big, have under the same shear strength situation, cost greatly reduces than the cost of the shaped steel-concrete combination beam that adopts the monomer-type shearing connecting piece.
The technical scheme that solves its above-mentioned technical problem is: a kind of shaped steel-concrete combination beam, comprise armored concrete slab, section steel beam and the shearing connecting piece between top reinforcement concrete slab and lower floor's section steel beam, it is characterized in that: described shearing connecting piece is made of the continuous wave shape wave reinforcing bar that is positioned on the section steel beam, the polygon that is shaped as trapezoid or is similar to of the single ripple of this waveform reinforcing bar with trapezoid, each trapezoidal top on the one side that links to each other with section steel beam and section steel beam welding are fixing, and each top of another side is stretched in the armored concrete slab.
Because adopt said structure, shaped steel-concrete combination beam of the present invention has the following advantages:
1, the shearing connecting piece of Cai Yonging can directly be bent into whole round steel, and making and installation are very easy;
2, because the shearing connecting piece that adopts is a continuous structure, the adhesion maximum of itself and concrete slab, anti-shear ability is stronger;
3, because the shearing connecting piece that adopts is a continuous structure, can in concrete slab, play the effect of longitudinal reinforcement, the reinforcing steel bar concrete strength.
Because above characteristics, shaped steel-concrete combination beam of the present invention has under the same shear strength situation as the spanning member of combined bridge, and cost reduces greatly than the cost of the shaped steel-concrete combination beam that adopts the monomer-type shearing connecting piece; Shaped steel-concrete combination beam of the present invention also can be used as the beams and slabs of other buildings in addition---as house beam, aqueduct joist, crane girder or the like.

The specific embodiment:
Embodiment one:
A kind of shaped steel-concrete combination beam, by armored concrete slab (1), section steel beam (3) and be positioned at top reinforcement concrete slab (1) and lower floor's section steel beam (3) between shearing connecting piece (21) form, described shearing connecting piece (21) is made of continuous wave shape wave reinforcing bar, the single ripple of this waveform reinforcing bar be shaped as trapezoid, described section steel beam is standard type girder steel or the section steel beam (3) that welded by steel plate, each trapezoidal top on one side that shearing connecting piece (21) links to each other with section steel beam and section steel beam (3) welding are fixing, and each top of another side is stretched in the armored concrete slab (1) (referring to Fig. 1, Fig. 3).
Embodiment two:
A kind of shaped steel one concrete combination beam, section steel beam that constitutes by armored concrete slab (1), with shaped steel truss (4) and the shearing connecting piece (22) that is positioned between top reinforcement concrete slab (1) and the lower floor's section steel beam are formed, described shearing connecting piece (22) is made of continuous wave shape wave reinforcing bar, the single ripple of this waveform reinforcing bar be shaped as trapezoid, upper chord (5) the end face welding of each trapezoidal top on the one side that links to each other with the shaped steel truss and shaped steel truss is connected, and (referring to Fig. 2, Fig. 4) in the armored concrete slab (1) stretched on each top of another side.
As a kind of conversion of the embodiment of the invention one, embodiment two, the shape of the single ripple of the described shearing connecting piece (21) that is made of continuous wave shape wave reinforcing bar, (22) can also be to clip the sinusoidal waveform on top or the polygon approximate with trapezoid.
Among above-mentioned two embodiment, the trapezoidal height h value of described waveform bar cutting connector is greater than and equals 1/3 of concrete slab thickness H, be h 〉=1/3H, the length D on the trapezoidal top that links to each other with section steel beam is generally more than or equal to 4 times of bar diameter Φ d, be D 〉=4 Φ d, angle α=45 of trapezoidal waist and section steel beam °.
