Abstract
The utility model discloses a high-strength composite concrete bridge pier column structure. The structure comprises a steel tube as well as an inner reinforced concrete column and outer concrete which are respectively poured inside and outside the steel tube, wherein longitudinal reinforcement and stirrups are arranged in the inner reinforced concrete column; and the stirrups are arranged along the radial direction of the steel tube, are sleeved outside the longitudinal reinforcement and are connected with the longitudinal reinforcement. The structure not only has high compressive strength but also has strong pull resistance.
Description
Technical field
The utility model relates to a kind of bridge pier structure, is 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 bridge pier post all is very widely.The effect of bridge pier rod structure in bridge construction is vital, and it is one of topmost load-carrying members.Will pass through a lot of vehicles every day on the bridge, little of private car, arrives the load-carrying lorry greatly, so one of key element that safety problem is people to be paid attention to very much.And as the bridge pier post of major bearing structures, its bearing strength and tension degree are exactly The key factor very.
The utility model content
The utility model has overcome the deficiency of prior art, provides a kind of high strength compound concrete bridge pier column structure, and this utility model not only compressive strength is high, and anti-pull ability is strong.
For solving above-mentioned technical problem, the utility model adopts following technical scheme:
The compound concrete bridge pier column structure of a kind of high strength; It comprises the internal layer reinforced concrete post and the outer concrete of building respectively inside and outside steel pipe and the steel pipe, and the reinforcing bar in the described internal layer reinforced concrete post has longitudinal reinforcement and stirrup, and 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 it is outer and longitudinal reinforcement connected together to be enclosed within longitudinal reinforcement.Main bearing structure is the internal layer reinforced concrete post, in the internal layer reinforced concrete post longitudinal reinforcement is arranged, and has strengthened its anti-pressure ability.Longitudinal reinforcement is with stirrup outward, is convenient to fixedly longitudinal reinforcement.Between internal layer reinforced concrete post and the outer concrete steel pipe is arranged, strengthened its anti-pull ability.
Technical scheme further is:
The thickness of described outer concrete is less than or equal to 1/10 of the compound concrete bridge pier column structure radius of described high strength.The main bearing structure of the compound concrete bridge pier column structure of high strength is the internal layer reinforced concrete post, and outer concrete also can play the pressure-bearing effect, but it mainly is the 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 in the center of circle of the intersection point of its major axis and minor axis and steel pipe.Circular cross-section is big apart from frequently for the maximum bending resistance inertia of elliptic cross-section under situation of the same area, therefore in that to reach under the situation of identical stress the comparable circular section of oval cross section little, thereby has saved concrete amount.
Compared with prior art, the beneficial effect of the utility model is:
1, is embedded with reinforced frame in the inner concrete, strengthened the bearing strength of bridge pier column.
2, be provided with steel pipe between the inside and outside concrete, strengthened the resistance to tension of bridge pier column.
3, outer concrete is arranged to ellipse, can saves material to a certain extent, reach the effect of practicing thrift cost.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.
Fig. 1 is that the outer concrete of the utility model is circular structural representation.
Fig. 2 is oval-shaped structural representation for the outer concrete of the utility model.
Label among the 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 utility model is further described.The embodiment of the utility model includes 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 the internal layer reinforced concrete post 3 and outer concrete 4 of building respectively inside and outside steel pipe 2 and the steel pipe 2, and the reinforcing bars in the internal layer reinforced concrete post 3 have longitudinal reinforcement 1 and stirrup 5, and 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 it is outer and longitudinal reinforcement 1 connected together to be enclosed within longitudinal reinforcement 1.The thickness of outer concrete 4 is less than or equal to 1/10 of the compound concrete bridge pier column structure radius of described 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 the internal layer reinforced concrete post 3 and outer concrete 4 of building respectively inside and outside steel pipe 2 and the steel pipe 2, and the reinforcing bars in the internal layer reinforced concrete post 3 have longitudinal reinforcement 1 and stirrup 5, and 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 it is outer and longitudinal reinforcement 1 connected together to be enclosed within longitudinal reinforcement 1.The thickness of outer concrete 4 is less than or equal to 1/10 of the compound concrete bridge pier column structure radius of described 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 utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the utility model.
