Description
Technical field
The utility model belongs to bridge structure rapid construction, prefabrication technical field of construction.
Background technology
The concept of prefabricated installation is accepted already, but mainly to superstructure.Beams of concrete or girder steel are in factory
After completing, building site is transported to, only waits Bent beam to finish, it is possible to which roof beam structure is got on.At present, prefabricated installation concept expands
Open up substructure.Bent cap and column start to be prefabricated in the factory, then transport to building site installation.For example, the U.S. some without earthquake
Area has been carried out this technique if (such as moral gram Long Si states).But in some earthquake prone areas, just seldom in this way.
From construction, two components of column and bent cap use prefabricated installation most convenient.Because they are all straight-bars, make, transport, hang
Dress is all very simple.But in earthquake areas, problem is exactly appeared on both linkage interfaces.From antidetonation angle, this interface
It is most critical position, it is desirable to which the position will have enough intensity and ductility.And in most cases, the prefabricated peace of bent cap column
Dress can cause anti-seismic performance to decline.
The domestic research of substructure precast segment assembling technique and application are relatively fewer, but just gradually obtain China engineer
Concern and attention.Precast segment assembly bridge pier is that bridge is vertically divided into some block parts, such as cushion cap, post, bent cap, work
Factory is prefabricated, transports to construction site, on-site consolidation.Engineering prefabricated components easily standardize, the advantages of more playing precasting process：
Pre-fabricated factory, it is easy to quality control；It is small to surrounding enviroment and traffic impact；Can effectively eliminate danger region job safety it is hidden
Suffer from；Precast concrete shrinkage and creep is small etc..
In huge highway bridge colony, there are about 1/4 bridge is weathered out-of-date or afunction.That is,
There is thousands of bridge to need repairing, reinforce or change.The transformation and upgrade of bridge, undoubtedly part of taking a long view is meddlesome, is
It is necessary；But consider from instantly, it can bring the deuce to pay to daily traffic.Break off a friendship, traffic disturbance can not only be caused by detouring, and
And user's delay time at stop and unnecessary fuel consumption can be also caused, economic loss is huge.Therefore, process is reconstructed in bridge strengthening
In, it should try one's best and shorten the duration, minimally disturb traffic.
It undoubtedly can more be speeded up the work than cast-in-place using the construction of prefabricated installation method, reduce field operation time, this is
The conclusion having already been confirmed.Prefabricated mounting process can be completed with parallel operations, extensive work in factory, few occupancy scene
Room and time, it is not necessary to close traffic for a long time and detour.In addition, also reduce the danger that worker works in chaotic scene
Property.
Existing each component connecting node of prefabricated substructure technology is still to be tested in the reliability that high earthquake region uses.
The content of the invention
The purpose of this utility model is to provide a kind of prefabricated substructure of highway bridge and is connected locating structure with basis, to solve
The installation positioning of integrated prefabricated bridge substructure component, both speeded up the work, and reduced field operation time, make both again
The position of linkage interface will have the technical problems such as enough intensity and ductility.
To achieve these goals, technical essential is as follows used by the utility model：
A kind of prefabricated pier of highway bridge is connected locating structure with basis, including bent cap and the integrated prefabricated bridge bottom of pier stud
Component, cast-in-place basis, basis top fixing steel plate, ring flange, pier stud steel plate hoop and WELDING STUDS；It is existing in stretching into for concrete knoll
Part in casting foundation rim of a cup, outside are fixed with pier stud steel plate hoop, and concrete knoll lowermost end is provided with to be connected with pier stud steel plate hoop
The end socket steel plate connect；WELDING STUDS is set on the outside of steel plate hoop, filled between cast-in-place basic rim of a cup and pier stud steel plate hoop fast hard high
Reinforced concrete；Ring flange is fixed with the top of cast-in-place basic rim of a cup, it is fixed that ring flange upper end radial is provided with some basis tops
Position steel plate, the inner faces of some basis tops fixing steel plates are connection positioning end, itself and pier stud steel plate hoop Site Welding.
The dowel of cross arrangement, the outer end of dowel and the foot stall steel of outside fixation are embedded with inside the concrete knoll
Plate hoop connects.
The utility model has the advantages that it can be used in positioning prefabricated components pier stud, it is ensured that pier before rapid hardening high-strength concrete hardening
Post perpendicularity.Solve the prefabricated substructure connectivity problem in high earthquake region simultaneously, Short/Medium Span Bridge rapid construction requirement can be met, had
Effect shortens the duration, reduces bridge construction to traffic impact.This patent is particularly suitable for use in the high existing Bridge Reconstruction of earthquake region heavy traffic
Engineering.
