Description
Technical field
The utility model relates to civil construction projects, and the construction of cracking is prevented especially suitable for cable-stayed bridge curve concrete Sarasota.
Background technique
The Sarasota of cable-stayed bridge generallys use concrete structure, the small eccentricity component based on being pressurized.For to Sarasota landscape
There is the concrete pylon of surface modeling in recent years in the needs of moulding, and structure is compression member with large eccentricity, make Sarasota section
There is tension.For control cord tower section tensile stress, Sarasota section is made to crack, cracking resistance tectonic sieving is used to Sarasota, is mentioned
The endurance quality and security performance of high Sarasota.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of curve concrete Sarasotas to prevent cracking from constructing, with effectively anti-
Only large eccentricity component crack in tension improves the endurance quality of curve concrete Sarasota.
It is as follows that the utility model solves technical solution used by its technical problem:
The curve concrete Sarasota of the utility model prevents cracking from constructing, and curve concrete Sarasota is by left side pier stud, right side pier stud, crossbeam
Constituted with cushion cap, pier stud on the left of curved shape, right side pier stud top consolidation be integrated, lower end and cushion cap consolidate, crossbeam both ends point
It is not consolidated with left side pier stud, right side pier stud, it is characterized in that: the direction across bridge side wall of the tensile region of the left side pier stud, right side pier stud
Interior laying vertical prestressing steel beam, and prestressing force is applied by tensioning vertical prestressing steel beam, keep curve concrete Sarasota total cross-section equal
In pressured state.
The left side pier stud, the direction across bridge inner sidewall of right side pier stud bury anticracking reinforced mesh in direction across bridge lateral wall.
The left side pier stud, right side pier stud and crossbeam are poured by C55 steel fiber reinforced concrete.
The utility model has the beneficial effects that making Sarasota total cross-section after Sarasota section tensile zone arranges vertical prestressing
It is in pressured state, solves the problems, such as large eccentricity component crack in tension；Using steel fiber reinforced concrete plus surface layer reinforced mesh
Concrete surface crack problem in work progress is effectively solved, the endurance quality of Sarasota is improved.
Detailed description of the invention
This specification includes following three width attached drawing:
Fig. 1 is the main view that the utility model curve concrete Sarasota prevents cracking from constructing；
Fig. 2 is the cross-sectional view that the utility model curve concrete Sarasota prevents pier stud direction across bridge inner sidewall in cracking construction；
Fig. 3 is the cross-sectional view that the utility model curve concrete Sarasota prevents pier stud direction across bridge lateral wall in cracking construction；
Component and corresponding label be shown in figure: left side pier stud 1, right side pier stud 2, crossbeam 3,4, first groups of cushion cap it is vertically pre-
Stress steel beam N1, second group of vertical prestressing steel beam N2, third group vertical prestressing steel beam N3, the 4th group of vertical prestressing steel beam
