Description
(1) technical field
The present invention relates to a kind of overpass bridge pier, particularly to a kind of leaf bud type bridge pier.
(2) background technology
Overpass uses circular reinforced concrete bridge pier mostly at present, and it is simple that it has construction, and construction technology is ripe, outward
The advantages such as shape brief introduction is attractive in appearance, are therefore widely adopted in Medium and small span bridge.But existing circular bridge pier column majority is adopted
Using solid circles cross section, concrete generally individually uses non-high-strength concrete, concrete material large usage quantity.Field cast-in-place construction week
Phase is long, and the environment of surrounding also can be produced certain destruction.
The aspects such as durability, the feature of environmental protection, economy, aesthetic property, original cylinder is focused in modern Bridge Design theory
Pier stud and post-stressed bridge pier can not meet requirement the most, it is necessary to by technological innovation, adapt to new century
The demand of the development of traffic engineering.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, enriches view and the practicality of Selection of Urban Pedestrian Overpass substructure
Property, it is provided that the overpass bridge pier of a kind of solid geometry structure.
The present invention is achieved through the following technical solutions:
A kind of leaf bud type bridge pier, including foundation platform, the internal landfill of described foundation platform has anchoring built-in fitting, and this anchoring is pre-
Embedded part top is positioned at foundation platform upper surface；Described anchoring built-in fitting top is welded with 4 concrete filled steel tube pier stud bottoms respectively
Together；Described concrete filled steel tube pier stud bottom end surface is provided with anchoring peg, and this concrete filled steel tube pier stud bottom has poured anchoring
Cushion cap；Described concrete filled steel tube pier stud is curved, and 2 relative concrete filled steel tube pier studs are symmetrical arranged, 4 steel tube concrete knolls
Capital end is connected with each other；Described adjacent 2 are provided with bearing beam in the middle of concrete filled steel tube pier stud；Described bearing beam is provided with rubber and props up
Seat, is provided with stiffened steel plates at this rubber support lower end bearing beam.
Described foundation platform and anchoring cushion cap are formed by concreting.
Described anchoring peg diameter 16mm, spacing 100mm, and anchoring peg are distributed in concrete filled steel tube pier stud bottom 0-
In 550mm altitude range.
Described concrete filled steel tube pier stud is outside is steel pipe, and the steel duct below bearing beam has poured concrete.
Described bearing beam is rectangle steel box-beam structure.
Entirety of the present invention is rendered as " leaf bud " type, and the entirety that four curved steel tube performance of concrete column confineds are arranged symmetrically with composition presents
For the bridge pier structure of leaf bud, concrete filled steel tube pier stud about 1/2 height and position sets bearing beam, and bearing beam is that steel construction rectangular box cuts
Face, bearing beam support bridge socle structure, four arc bridge piers are connected into entirety, it is ensured that bridge pier entirety stress simultaneously, and support
The outer tension force that extinguishing arc shape pier stress produces, bearing beam sets rubber support, and sky bridge girder falls within rubber support, rubber support
Bearing beam below position is reinforced with stiffened steel plates.
The invention has the beneficial effects as follows: bridge pier globality stress of the present invention, the design of possessive construction details is and reaches to make
Pier stud can overall, uniform stressed, the vertical load of shared girder, reach theoretical stress and design matching of stress,
Make Selection of Urban Pedestrian Overpass reach moulding in shape-designing to combine together with structure simultaneously, both beautiful and practical, it is worthy to be popularized.
(4) accompanying drawing explanation
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the three-dimensional shaft view of the present invention.
Fig. 2 is the local structural graph of the present invention.
Fig. 3 is the structure chart of the anchoring cushion cap of the present invention.
Fig. 4 is the linear graph of the concrete filled steel tube pier stud of the present invention.
In figure, 1 foundation platform, 2 anchoring cushion caps, 3 anchoring built-in fittings, 4 concrete filled steel tube pier studs, 5 anchoring pegs, 6 stress
Beam, 7 stiffened steel plates, 8 rubber supports.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment includes foundation platform 1, and described foundation platform 1 is internal
Landfill has anchoring built-in fitting 3, and this anchoring built-in fitting 3 top is positioned at foundation platform 1 upper surface；Described anchoring built-in fitting 3 top is divided
Do not weld together with 4 concrete filled steel tube pier stud 4 bottoms；Described concrete filled steel tube pier stud 4 bottom end surface is provided with anchoring peg
5, this concrete filled steel tube pier stud 4 bottom has poured anchoring cushion cap 2；Described concrete filled steel tube pier stud 4 is curved, 2 relative steel
Pipe concrete pier stud 4 is symmetrical arranged, and 4 concrete filled steel tube pier stud 4 tops are connected with each other；Described adjacent 2 with steel tube concrete knoll
It is provided with bearing beam 6 in the middle of post 4；Described bearing beam 6 is provided with rubber support 8, is provided with and adds at this rubber support 8 lower end bearing beam 6
Strength steel plate 7.Described foundation platform 1 and anchoring cushion cap 2 are formed by concreting.Described anchoring peg 5 diameter 16mm, spacing
100mm, and anchoring peg be distributed in the 0-550mm altitude range of concrete filled steel tube pier stud 4 bottom.Described concrete filled steel tube pier stud
4 outsides are steel pipe, and the steel duct of bearing beam less than 6 has poured concrete.Described bearing beam 6 is rectangle steel box-beam structure.
Pier Design is become leaf bud type, the height dimension of leaf bud type, pier stud arc radius and pier stud and stress by the present invention
The size of beam all can be adjusted according to the needs of Practical Project.Foundation platform 1 and concrete filled steel tube pier stud 4 use anchoring pre-
Embedded part 3 realizes transition and connects, and the design of anchoring built-in fitting 3 needs to carry out in strict accordance with related specifications and force request, and anchoring is pre-
The construction of embedded part 3 should ensure that construction quality, it is ensured that the reliability of component.Pier stud should first ensure that when welding with anchoring pre-embedded steel slab
Blank size bottom pier stud meets design requirement, scale error and welding quality and should require to perform in strict accordance with related specifications.
Anchoring peg 5 bottom anchoring cushion cap 2 and concrete filled steel tube pier stud 4 is enhancing pier stud bottom safety design, and two structures are all
Globality and shearing strength with anchoring cushion cap 2 bottom concrete filled steel tube pier stud 4 can be improved.Pier stud bearing beam less than 6 designs
For concrete filled steel tube, bending strength and the shearing strength of concrete filled steel tube pier stud 4 can be improved, strengthen steel tube concrete knoll
The stability in the large of post 4.Four concrete filled steel tube pier studs 4 are connected as the primary structure member that entirety becomes main by bearing beam 6, and are subject to
Power beam 6 itself also serves as transmitting the important component of girder vertical load, and therefore the design of bearing beam is the most crucial.
