Described vertical chord member has two kinds of forms, and be positioned at middle vertical chord member and adopt H profile steel, the vertical chord member being positioned at corner adopts angle steel; Described lateral ties bar and oblique contact bar adopt angle steel or bar shaped steel.
Described connector is arranged on vertical chord member, and it can be the perforate of the perforated panel of weldering nail, welding, vertical chord member or shaped steel outer wrapping spiral bar.Vertical chord member arranges connector and can ensure collaborative work between steel structure and Reinforced Concrete Pier Column.
Described steel structure is provided with three road stirrups, often comprises together vertically spacedly arranging stirrup more, wherein: the periphery of steel structure is located at by first stirrup; Second stirrup is located in the middle of steel structure, and it is through the perforate on vertical chord member web and as the part of connector; The inward flange of steel structure is located at by 3rd road stirrup.
Described stirrup is designed to circular arc in Gang Gou corner and smoothly transits.
Described steel structure peripheral the separation along circumferential direction is provided with many vertical muscle, but makes stressed ripping circular saw significantly lower than ordinary concrete pier stud under equal stress condition.
The utility model has following beneficial effect:
(1) the utility model steel structure-Combined concrete height pier structure is under bridge completion state, concrete pier mainly bears vertical force component in high pier, steel structure assists concrete to bear moment of flexure in cross section, and concrete is wrapped in the stability that can increase steel structure structure outside steel structure.
(2) connector that arranges between steel structure and concrete of the utility model, can guarantee between the two can Transfer of Shear, ensures collaborative work.
(3) when the utility model steel structure is arranged in performance of concrete column confined, assume responsibility for most cross section unbending, reduce the main muscle quantity of reinforcement in reinforced concrete for high piers cross section.Only need arrangement reinforcing bar in cross section and be connected auxiliary reinforcement, playing and prevent concrete cracking, restriction concrete crack width, and ensureing the acting in conjunction between steel structure and concrete.
(4) the utility model steel structure-Combined concrete height pier, the part originally as the interim stiff skeleton of construction can be used by rational structure, without the need to removing, decreasing working procedure, simplifying design process.
(5) when adopting the utility model can reduce high pier construction, the consumption of temporary steel structure, increases the volume of the circular flow of template, reaches accelerating construction progress, provide convenient construction, saves operating expenses.
