Abstract
The invention discloses a high-strength composite concrete bridge pier stud structure. The high-strength composite concrete bridge pier stud structure comprises a steel pipe, an inner-layer reinforced concrete column and outer-layer concrete, wherein the inner-layer reinforced concrete column is poured in the steel pipe, and the outer-layer concrete is poured outside the steel pipe. Steel bars in the inner-layer reinforced concrete column comprise longitudinal steel bars and stirrups, wherein the stirrups are arranged in the radial direction of the steel pipe, and the longitudinal steel bars are sleeved with the stirrups and connected together through the stirrups. The high-strength composite concrete bridge pier stud structure is high in compressive strength and strong in anti-pulling capability.
Description
Technical field
The present invention relates to a kind of bridge pier structure, be specifically related to the compound concrete bridge pier column structure of a kind of high strength.
Background technology
In many engineer operations, for example overpass bridge and viaduct, the application of pier column is all very widely.The effect of pier column structure in bridge construction is vital, and it is one of topmost load-carrying members.On bridge, will pass through a lot of vehicles every day, little of private car, arrives greatly load truck, so one of key element that safety problem is people to be focused on very much.And as the pier column of major bearing structures, its bearing strength and tension degree are exactly very crucial factor.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, provides a kind of high strength compound concrete bridge pier column structure, and this is invented, and not only compressive strength is high, and anti-pull ability is strong.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
The compound concrete bridge pier column structure of a kind of high strength, it comprises internal layer reinforced concrete post and the outer concrete of building respectively inside and outside steel pipe and steel pipe, reinforcing bar in described internal layer reinforced concrete post has longitudinal reinforcement and stirrup, described longitudinal reinforcement has four at least, and axially evenly distributed along steel pipe, described stirrup has four at least, and along radially the arranging of steel pipe, and is enclosed within longitudinal reinforcement outer and longitudinal reinforcement is connected together.Main bearing structure is internal layer reinforced concrete post, in internal layer reinforced concrete post, has longitudinal reinforcement, has strengthened its anti-pressure ability.Longitudinal reinforcement overcoat has stirrup, is convenient to fixedly longitudinal reinforcement.Between internal layer reinforced concrete post and outer concrete, there is steel pipe, strengthened its anti-pull ability.
Further technical scheme is:
The thickness of described outer concrete is less than or equal to 1/10 of the described compound concrete bridge pier column structure radius of high strength.The main bearing structure of the compound concrete bridge pier column structure of high strength is internal layer reinforced concrete post, and outer concrete also can play pressure-bearing effect, but it is mainly protection steel pipe, so be difficult for too thick.
Described outer concrete is circular, and coaxial with steel pipe.Circle is the selection of most of bridge piers, and from aesthetics, it is very attractive in appearance.
Described outer concrete ovalisation, and the same point of the intersection point of its major axis and minor axis and the center of circle of steel pipe.In situation of the same area, circular cross-section is large apart from frequently for the maximum bending resistance inertia of elliptic cross-section, and therefore in the situation that reaching identical stress, the comparable circular section of oval cross section is little, thereby has saved concrete amount.
Compared with prior art, the invention has the beneficial effects as follows:
1, in inner concrete, be embedded with reinforced frame, strengthened the bearing strength of bridge pier column.
2, between inside and outside concrete, be provided with steel pipe, strengthened the resistance to tension of bridge pier column.
3, outer concrete is arranged to ellipse, can saves material to a certain extent, reach cost-saving effect.
Accompanying drawing explanation
?below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
Fig. 1 is that the outer concrete of the present invention is circular structural representation.
Fig. 2 is that the outer concrete of the present invention is oval-shaped structural representation.
Label in figure is: 1, longitudinal reinforcement; 2, steel pipe; 3, internal layer reinforced concrete post; 4, outer concrete; 5, stirrup.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.Embodiments of the present invention include but not limited to the following example.
The compound concrete bridge pier column structure of a kind of high strength as shown in Figure 1, it comprises internal layer reinforced concrete post 3 and the outer concrete 4 of building respectively inside and outside steel pipe 2 and steel pipe 2, reinforcing bar in internal layer reinforced concrete post 3 has longitudinal reinforcement 1 and stirrup 5, longitudinal reinforcement 1 has four at least, and axially evenly distributed along steel pipe 2, stirrup 5 has four at least, and along radially the arranging of steel pipe 2, and is enclosed within longitudinal reinforcement 1 outer and longitudinal reinforcement 1 is connected together.The thickness of outer concrete 4 is less than or equal to 1/10 of the described compound concrete bridge pier column structure radius of high strength.Outer concrete 4 is circular, and coaxial with steel pipe 2.
The compound concrete bridge pier column structure of a kind of high strength as shown in Figure 2, it comprises internal layer reinforced concrete post 3 and the outer concrete 4 of building respectively inside and outside steel pipe 2 and steel pipe 2, reinforcing bar in internal layer reinforced concrete post 3 has longitudinal reinforcement 1 and stirrup 5, longitudinal reinforcement 1 has four at least, and axially evenly distributed along steel pipe 2, stirrup 5 has four at least, and along radially the arranging of steel pipe 2, and is enclosed within longitudinal reinforcement 1 outer and longitudinal reinforcement 1 is connected together.The thickness of outer concrete 4 is less than or equal to 1/10 of the described compound concrete bridge pier column structure radius of high strength.Outer concrete 4 ovalisation, and the same point in the center of circle of the intersection point of its major axis and minor axis and steel pipe 2.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, within all falling into protection scope of the present invention.
