Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] Such as Figure 1 to Figure 6 , the present invention is an assembled T-beam bridge assembly-type lateral connection reinforcement. The T-beam bridge is composed of several T-shaped main girders 1, and a connecting joint 2 is provided between two adjacent T-shaped main girders 1. Each The bottom end of a T-shaped main beam 1 is provided with a T-beam horseshoe 100, which is used to reinforce the structure and is arranged between two adjacent T-shaped main beams 1, including a steel concrete composite backing plate 3, a top plate, a diagonal support 7 and a horizontal Support 9, the top plate is fixedly connected on the lower surface of the connecting joint 2 and the adjacent two T-shaped main beams 1, the steel concrete composite backing plate 3 is fixedly connected on the lower surface of the top plate, and the bottom ends of the two diagonal supports 7 are fix...

Abstract

The invention discloses a combination T beam bridge assembly type cross connection reinforced structure and a reinforcing method thereof. A top plate is fixedly connected to joint seams and the lowersurfaces of two adjacent T-shaped girders, a steel concrete combination base plate is fixedly connected to the lower surface of the top plate, the bottoms of two inclined supports are fixedly connected to T-shaped horseshoe parts of the two T-shaped girders, the tops of the two inclined supports are fixedly connected to the steel concrete combination base plate, and the two ends of a horizontal support are fixedly connected with the T-shaped horseshoe parts of the two T-shaped girders; the two inclined supports and the horizontal support form a triangular support structure. Accordingly, the defects that for a traditional cross connection reinforcing method, the construction period is long, the effect is poor, many limiting factors exist, and the construction condition requirements are highare overcome, the technical problem that combination T beam bridge cross connection urgently needs to be improved is solved. The structure can be widely applied to cross connection reinforcing of a combination T beam bridge and a concrete box beam bridge, and meanwhile the structure can also serve as a diaphragm plate of a new bridge for use.

Description

Technical field: [0001] The invention relates to an assembled transverse connection reinforcement structure of a combined T-beam bridge and a reinforcement method thereof. Background technique: [0002] Small and medium-span bridges are generally constructed using composite T-girder bridges. The T-shaped cross-section beam reduces the tensile area of ​​the concrete and greatly reduces the self-weight of the structure. At the same time, the compressive performance of concrete and the tensile performance of steel bars are fully utilized. Because it does not require on-site installation of formwork, it is easy to erect and low in cost, and is widely used in bridges with small and medium spans. In recent years, with the increase of vehicles and lack of adequate maintenance, bridges have suffered varying degrees of damage, including carbonation of concrete, increase of cracks and corrosion of steel bars. Among them, the insufficient transverse connection is one of its most s...
