Description
Technical field
The present invention relates to precast beam fields, more particularly, to a kind of steel, concrete combination beam.
Background technique
T plate is the solidifying native bearing carrier of precast reinforced rolling of plate, beam combination, by roomy panel and two narrow and high ribs
Composition, panel is both the compressive region of transverse bearing structure and longitudinal load-bearing rib.Compressive region section is larger, and natural axis is close
Or entering panel, tension main reinforcement has the biggish arm of force.So T plate has good structural mechanical property, specific power transmission
Level, succinct geometry are the bearing carriers of a kind of large span, big area coverage.Prestressing force T plate span is up to 20 meters
More than, up to 30 meters or more if with high-strength lightweight concrete.
But the most fatal problem of T plate, which is exactly that end is anti-, pushes away that performance is poor, and prestress steel is almost nil in end pulling force, and grain
The lateral pressures such as library, garage are big, and anti-to plate end to push away more demanding, therefore T plate is unable to reach requirement.
Summary of the invention

The width of straight-bar and the width fits of U-shaped board.
By using above-mentioned technical proposal, U-shaped board limits straight-bar, prevents straight-bar from being bent to the width direction of beam, mentions
The high support effect of straight-bar.
Preferably, section of the steel tank along beam width direction is T-shaped, and upper and lower two layers of steel is worn in every steel tank
Muscle, top bars quantity are three, and lower layer's number of steel bars is one.
By using above-mentioned technical proposal, the multistory reinforced connective stability for improving steel tank and reinforcing bar is also improved
The connective stability of square steel and reinforcing bar.
Preferably, the attachment base includes the first I-steel being vertically arranged, and the grooves on two sides of the first I-steel is interior from upper
Several transverse slats are horizontally fixed under；Short rib includes the first short rib and the second short rib, and the first short rib is located at the both ends of long rib, and first
The end of short rib is inserted into the groove of the first I-steel side and is welded and fixed.
By using above-mentioned technical proposal, the structural strength of attachment base and long rib is improved.
Preferably, the long rib includes the second I-steel, is fixed vertically from left to right in the outside groove of the second I-steel
There are several risers, the end of the second short rib is inserted into the second I-steel inboard groove.
By using above-mentioned technical proposal, the working strength of long rib is improved.
Preferably, the described second short rib is C-type steel, and the upper and lower two sides of the second short rib are equipped with notch, and it is short that notch passes to second
The end of rib, the bottom surface of notch and the inner wall of the second I-steel inboard groove are smooth, and the second short rib is welded and fixed with long rib.
By using above-mentioned technical proposal, the structural strength of the second short rib Yu long rib junction is improved.
Preferably, several angle steel are fixedly connected between two root long ribs, an angle steel, phase is set between every adjacent two short ribs
