Abstract
The utility model provides a kind of bridge strengthening structure, includes bridge pier, bridge floor, steel bar framework, transverse bar, former transverse bar, dowel.The bridge pier is the concrete support pedestal of bridge.The bridge floor is concrete walking road surface of the build of bridge above bridge pier.The steel bar framework is the bar construction for being arranged in bridge pier surrounding, and connecting in bridge floor bottom surface.The transverse bar is the bar construction that inside on bridge pier bottom reinforcement bars frame is arranged in transverse weld.The original transverse bar is the bar construction that bottom is laterally arranged in bridge pier.The dowel is the fixed steel bars for being implanted into bridge pier and bridge floor bottom surface.The utility model bridge strengthening structure, can be in the case where not destroying former bridge, and the overall structure of reinforcement bridge enhances the stability of bridge, and low cost, convenient for construction.
Description
Technical field
The utility model relates to bridge construction field more particularly to a kind of bridge strengthening structures.
Background technique
With the development of social economy, the magnitude of traffic flow is growing, the ability that is open to traffic of some old bridges of highway, carrying water
The flat demand for being no longer satisfied the volume of traffic is detected original bridges and culverts framework there are certain disease by the operation of more than ten years,
Need to carry out improvement reinforcing, bridge pier often occurs various cracks during military service, structural bearing capacity is caused to decline, since beam body is cut
Face size is small to show as that the section bending resistance moments of inertia is small, and bending bearing capacity is small at span centre position, leads to bending strength, insufficient rigidity,
The diseases such as appearance transverse crack and amount of deflection are excessive, if carrying out reinforcing not in time will cause damages to the use of bridge, still
Existing some reinforcement technique complicated construction techniques, difficulty is larger, and consolidation effect is also difficult to ensure.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of Scheme for Bridge Strengthening by Using, the technology
Scheme is achieved in that
A kind of bridge strengthening structure includes bridge pier, bridge floor, steel bar framework, transverse bar, former transverse bar, dowel.
The bridge pier is the concrete support pedestal of bridge.The bridge floor is concrete of the build of bridge above bridge pier
Walking road surface.The steel bar framework is the bar construction for being arranged in bridge pier surrounding, and connecting in bridge floor bottom surface.The transverse bar is
The bar construction of inside on bridge pier bottom reinforcement bars frame is arranged in transverse weld.The original transverse bar is that bottom is laterally arranged in bridge pier
Bar construction.The dowel is the fixed steel bars for being implanted into bridge pier and bridge floor bottom surface.
Preferably, the steel bar framework is 200mm at a distance from bridge pier surface.
Preferably, being divided into 300mm between the setting of the transverse bar.
Preferably, the depth of the dowel implantation bridge pier is 500mm.
The utility model bridge strengthening structure, can be in the case where not destroying former bridge, the overall structure of reinforcement bridge,
Enhance the stability of bridge, and low cost, convenient for construction.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is bridge strengthening structural schematic diagram.
Appended drawing reference: 1- bridge pier, 2- bridge floor, 3- steel bar framework, 4- transverse bar, 5- original transverse bar, 6- dowel.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of bridge strengthening structure, include bridge pier 1, bridge floor 2, steel bar framework 3, transverse bar 4, former transverse bar 5,
Dowel 6.
The bridge pier 1 is the concrete support pedestal of bridge.The bridge floor 2 is that the build of bridge is mixed above bridge pier 1
Solidifying soil walking road surface.The steel bar framework 3 is the bar construction for being arranged in 1 surrounding of bridge pier, and connecting in 2 bottom surface of bridge floor.Institute
Stating transverse bar 4 is the bar construction that inside on 1 bottom reinforcement bars frame 3 of bridge pier is arranged in transverse weld.The original transverse bar 5 is bridge pier 1
The bar construction that interior bottom is laterally arranged.The dowel 6 is the fixed steel bars for being implanted into 1 pier of bridge and 2 bottom surface of bridge floor.
When it is implemented, the steel bar framework 3 is 200mm at a distance from 1 surface of bridge pier.
When it is implemented, being divided into 300mm between the setting of the transverse bar 4.
When it is implemented, the depth that the dowel 6 is implanted into bridge pier 1 is 500mm.
