Abstract
The utility model relates to a box type prestressed concrete cap beam structure applied to a gate-type pier. Traditional cap beams of the gate-type pier are mostly of a rectangular solid concrete structure or a box type steel structure; the rectangular solid concrete structure is large in masonry quantity and self weight, only an in-situ support cast-in-place scheme can be adopted, the construction period of the rectangular solid concrete structure is long, and the influence on running of an existing road is large; the box type steel structure is high in engineering cost, large in later-period maintenance workload and difficult to inspect and maintain. According to the box type prestressed concrete cap beam structure applied to the gate-type pier, a box beam common section, box beam transition sections and anchorage sections are sequentially arranged from the center to the two sides. The box beam common section and the box beam transition sections are both of a hollow structure, and respectively comprise a top plate, web plates on the two sides and a bottom plate. The anchorage sections are of a solid structure and fixedly arranged at the tops of pier columns. Short steel cables are tensioned within the range of the box beam common section and the box beam transition sections on the two sides of the box beam common section. Long steel cables are tensioned within the whole cap beam structure, wherein the middles of the long steel cables are lower than the two ends. According to the box type prestressed concrete cap beam structure, the hollow box type prestressed concrete structure is adopted, prefabrication and lifting construction methods can be adopted, operation interference is reduced, elevation of lines is reduced, and engineering investment is reduced.
Description
Technical field
the utility model belongs to civil engineering bridge technology field, is specifically related to a kind of box pre-stressed concrete coping structure that is applied to transom pier.
Background technology
In recent years, China's traffic Foundation Design construction development is swift and violent, the development of the high-speed railway that the Line for Passenger Transportation of particularly take is representative and highway engineering high speed highway is particularly outstanding, circuit and existing busy trunk lines railway, the inevitably repeatedly graded crossing of existing busy trunk lines highway, when both angles hour, transom pier becomes a kind of selection of economical rationality, it can reduce to cross over the span of existing road and bridge greatly, cost saving, its economic benefit is very obvious, in Practical Project, is widely applied.
Rectangular solid cast-in-situ concrete bent cap structure or the steel bent cap structures of adopting in existing transom pier design more.Cast-in-situ concrete bent cap need to be set up support, concreting above existing road, its duration is grown and the operation of existing road is exerted an influence, particularly outstanding for its impact of existing busy trunk lines, while particularly crossing over existing railway, its embodiment can not obtain existing line manager's approval even sometimes; Another kind of transom pier-steel bent cap scheme, adopt steel work, deadweight lighter, generally adopt lifting construction, but this scheme exists engineering cost high, late maintaining workload is large, and is present in the shortcomings such as existing road (to existing railway at high-voltage contact net) top maintenance and inspection difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of box pre-stressed concrete coping structure that is applied to transom pier, is the bent cap structure designing for transom pier especially.
The technical scheme that the utility model adopts is:
A box pre-stressed concrete coping structure that is applied to transom pier, is characterized in that:
From mediad both sides, be followed successively by the general section of case beam, case beam changeover portion and anchoring section;
The general section of case beam and case beam changeover portion are hollow-core construction, by web and the base plate composition of top board, both sides, between top board and web, be provided with chamfering between base plate and web;
Anchoring section is entity structure, is consolidated in pier stud top.
In the scope of the case beam changeover portion of the general section of case beam and both sides, stretch-draw has short steel bundle, and stretch-draw is in the base plate of the general section of case beam and case beam changeover portion.
In complete section of bent cap structure of the general section of case beam, case beam changeover portion and anchoring section, stretch-draw has long steel bundle, and anchoring section end is fixed at two ends, and middle part is lower than two ends, and stretch-draw is in the base plate and web of the general section of case beam, case beam changeover portion and anchoring section.
The utlity model has following advantage:
The utility model adopts hollow box prestressed reinforced concrete construction, than the deadweight of mass concrete bent cap and steel strand consumption, reduce more than 30%, reduce basic bricklaying consumption, can adopt prefabrication and lifting construction, can greatly reduce existing road operation is disturbed, effectively reduce the elevation of circuit, design and construction are simple, save construction investment, reduce maintenance workload and the difficulty in later stage, more economical rationality, has wide application prospect.
Accompanying drawing explanation
Fig. 1 is the utility model elevation.
Fig. 2 is the utility model cross-sectional drawing.
In figure, general section of 1-case beam, 2-case beam changeover portion, 3-anchoring section, the short steel bundle of 4-1-, the long steel bundle of 4-2-, 5-pier stud, 6-top board, 7-chamfering, 8-web, 9-base plate.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in detail.
A kind of box pre-stressed concrete coping structure that is applied to transom pier that the utility model relates to, specially for transom pier design, is followed successively by the general section 1 of case beam, case beam changeover portion 2 and anchoring section 3 from mediad both sides.The general section 1 of case beam and case beam changeover portion 2 are hollow-core construction, form, between top board 6 and web 8, be provided with chamfering 7 between base plate 9 and web 8 by web 8 and the base plate 9 of top board 6, both sides.Anchoring section 3 is entity structure, is consolidated in pier stud 5 tops.In the scope of the case beam changeover portion 2 of the general section 1 of case beam and both sides, stretch-draw has short steel bundle 4-1, and stretch-draw is in the base plate 9 of the general section 1 of case beam and case beam changeover portion 2.In complete section of bent cap structure of the general section 1 of case beam, case beam changeover portion 2 and anchoring section 3, stretch-draw has long steel bundle 4-2, and anchoring section 3 ends are fixed at two ends, and middle part is lower than two ends, and stretch-draw is in the base plate 9 and web 8 of the general section 1 of case beam, case beam changeover portion 2 and anchoring section 3.
During construction, the general section 1 of prefabricated case beam and case beam changeover portion 2, the short steel bundle of stretch-draw 4-1, lifting, to designing transom pier position, is built anchoring section 3, and prefabricated case beam and pier stud 5 are linked together, anchoring section 3 reaches after stretch-draw requirement, implements the long steel bundle of stretch-draw 4-2, completes construction.
