Abstract
The utility model provides a kind of double-disk T bridge reinforcement structure, includes bridge pier, bridge floor, diaphragm plate, bar planting, vertical muscle, metope.The bridge pier is the concrete support pilum of T beam bridge.The bridge floor is the concrete T beam bridge surface being arranged in above bridge pier.The diaphragm plate is the symmetrical lateral connection concrete slab built and bridge pier top is arranged in bridge floor bottom.The bar planting is the high tensile reinforcement being arranged in inside diaphragm plate across bridge pier.The vertical muscle is to be welded in bar planting, connects the longitudinal reinforcement of bridge floor bottom and bridge pier bottom.The metope is to build in bridge pier inner surface, covers the concrete mortar of vertical muscle.The utility model double-disk T bridge reinforcement structure can reinforce the transverse splicing between two panels beam, improve the overall stability of bridge, and construction is simple in the case where not destroying former bridge structure.
Description
Technical field
The utility model relates to bridge construction field more particularly to a kind of double-disk T bridge reinforcement structures.
Background technique
At a high speed, heavy duty is the trend of Transportation Development from now on, and train is quick, comfortable and safe service requirement railroad bridge
Must have sufficiently large rigidity and good globality, biggish amount of deflection and amplitude occur to prevent bridge, after train speed raising,
Main problem existing for Existing Railway Bridges concentrates on lateral stiffness deficiency, and bridge lateral Oscillation Amplitude is excessive, directly affects row
Vehicle safety is the biggest obstacle of railway speed increase, is the bottleneck of completely speed-raising, under railway speed increase improvement project background, how
Scientific evaluation is carried out to both wired upper bridge structures, to determine which kind of measure reinforcing whether bridge need reinforcement and use, so as to
Planned, bridge of being done step by step, which updates, to be reinforced, and is enhanced the lateral stiffness of Existing Railway Bridges, is improved its overall stability,
The potentiality for giving full play to Existing Railway Bridges equipment are Existing railway promotion and railway speed increase problem in urgent need to solve.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of double-disk T bridge reinforcement scheme,
The technical solution is achieved in that
A kind of double-disk T bridge reinforcement structure includes bridge pier, bridge floor, diaphragm plate, bar planting, vertical muscle, metope.
The bridge pier is the concrete support pilum of T beam bridge.The bridge floor is the concrete T beam bridge being arranged in above bridge pier
Surface.The diaphragm plate is the symmetrical lateral connection concrete slab built and bridge pier top is arranged in bridge floor bottom.The bar planting
For the high tensile reinforcement inside diaphragm plate is arranged in across bridge pier.The vertical muscle is to be welded in bar planting, connects bridge floor bottom and bridge
The longitudinal reinforcement in pier bottom portion.The metope is to build in bridge pier inner surface, covers the concrete mortar of vertical muscle.
Preferably, the diaphragm plate forms plate more than the tabula for protruding 300mm-400mm on bridge pier upper outer surface.
Preferably, being divided into 100mm between the setting of the vertical muscle.
Preferably, the metope concrete mortar grade is consistent with former bridge.
The utility model double-disk T bridge reinforcement structure can reinforce two panels in the case where not destroying former bridge structure
Transverse splicing between beam improves the overall stability of bridge, and construction is simple.
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 double-disk T bridge reinforcement structural schematic diagram.
Appended drawing reference: 1- bridge pier, 2- bridge floor, 3- diaphragm plate, 4- bar planting, 5- indulge muscle, 6- metope.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of double-disk T bridge reinforcement structure, includes bridge pier 1, bridge floor 2, diaphragm plate 3, bar planting 4, indulges
Muscle 5, metope 6.
The bridge pier 1 is the concrete support pilum of T beam bridge.The bridge floor 2 is the concrete T that 1 top of bridge pier is arranged in
Beam bridge surface.The diaphragm plate 3 is the symmetrical lateral connection concrete slab built and 1 top of bridge pier is arranged in 2 bottom of bridge floor.Institute
Stating bar planting 4 is the high tensile reinforcement being arranged in inside diaphragm plate 3 across bridge pier 1.The vertical muscle 5 is to be welded in bar planting 4, connecting bridge
The longitudinal reinforcement of 1 bottom of 2 bottom of face and bridge pier.The metope 6 is to build in 1 inner surface of bridge pier, covers the concrete sand of vertical muscle 5
Slurry.
When it is implemented, the diaphragm plate 3 forms plate more than the tabula for protruding 350mm on 1 outer surface of bridge pier.
When it is implemented, being divided into 100mm between the setting of the vertical muscle 5.
When it is implemented, the 6 concrete mortar grade of metope is consistent with former bridge, concrete grade C15.
