Abstract
The utility model discloses a bridge pier structure with a square steel tube provided with stiffening ribs with openings and light steel fiber reinforced concrete. The bridge pier structure comprises the square steel tube; the inner side of the square steel tube is provided with the stiffening ribs uniformly; each stiffening rib is provided with the openings at a regular interval; and the light steel fiber reinforced concrete is filled in the square steel tube. The bridge pier structure is characterized by simplicity, reasonability, good load-carrying capability, and easy establishment and construction, and solves the problems of large self weight of a concrete-filled steel tube column and poor cohesion and integration between a steel tube and concrete.
Description
Technical field
The utility model relates to the bridge construction field of engineering technology, especially relates to a kind of concrete structure of establishing perforate stiffening rib square steel pipe lightweight steel fibrous concrete bridge pier.
Background technology
At present, because square steel tube concrete column has good ductility and bearing capacity performance in earthquake, thereby in industry and civilian construction, obtained using widely.In recent years, also adopted square steel tube concrete column in the bridge construction more and more, but because the flakiness ratio of the outer steel plate of post is bigger, general inside all is provided with floor, to strengthen the local stability of steel plate and concrete adhesion stress and steel plate.Steel core concrete column in the bridge mainly is used as bridge pier, outside steel plate double as template and primary structure member.But, the present several problems of steel core concrete column ubiquity:
1, the adhesion stress between steel pipe and the concrete is not enough, and the globality of combining structure is not enough;
2. the deadweight of steel core concrete column is bigger than normal, the limit structural size.
Summary of the invention
To defective that exists in the above-mentioned prior art or deficiency, the purpose of the utility model is, a kind of perforate stiffening rib square steel pipe lightweight steel fibrous concrete bridge pier of establishing is provided, and it is simple and reasonable and stress performance good, builds easy construction.
In order to realize above-mentioned task, the technical scheme that the utility model is taked is:
A kind of perforate stiffening rib square steel pipe lightweight steel fibrous concrete bridge pier of establishing comprises square steel pipe, it is characterized in that on pipe diameter, be evenly distributed with stiffening rib, the stiffening rib equal intervals is distributed with hole, is filled with the lightweight steel fibrous concrete in the steel pipe.
Other characteristics of the utility model are:
The profile of said square steel pipe is square or rectangle.
Be connected with welding manner between said stiffening rib and the square steel pipe.
The utility model establish perforate stiffening rib square steel pipe lightweight steel fibrous concrete bridge pier, compared with prior art have the following advantages:
1, simple and reasonable and stress performance good, from heavy and light, can solve the excessive problem of the existing deadweight of present steel core concrete column.
2, offer equally spaced hole adding on the vertical rib; After having filled the lightweight steel fibrous concrete; The concrete of two sides of stiffening rib all can be brought into play the shearing resistance effect, is mounted in the residing stress state of concrete in the steel plate hole, and its compressive strength is improved; Improve the steel pipe and the hypodynamic problem of concrete binding of present steel core concrete column greatly, also improved the globality of structure simultaneously.

Fig. 3 is the schematic cross-section of Fig. 1;
Mark among the figure is represented respectively: 1, square steel pipe, 2, stiffening rib, 3, hole, 4, the lightweight steel fibrous concrete.
Through accompanying drawing and embodiment the utility model is done further detailed description below.
The specific embodiment
As shown in Figure 1; Like Fig. 1～shown in Figure 3; Present embodiment provides a kind of concrete structure of establishing perforate stiffening rib square steel pipe lightweight steel fibrous concrete bridge pier, comprises square steel pipe 1, on square steel pipe 1 internal diameter, is evenly distributed with stiffening rib 2; Stiffening rib 2 equal intervals are distributed with hole 3, are filled with lightweight steel fibrous concrete 4 in the square steel pipe 1.
In actual building course, at first, on each stiffening rib 2, evenly offer a plurality of holes 3, then stiffening rib 2 is fixed on square steel pipe 1 inboard.In the practice, but welding manner connects between the two.At last, lightweight steel fibrous concrete 4 is cast between square steel pipe 1 and perforate stiffening rib 2 and the hole 3, makes and fill up lightweight steel fibrous concrete 4 in the square steel pipe 1.
Present embodiment is processed establishes perforate stiffening rib square steel pipe lightweight steel fibrous concrete bridge pier, and deadweight is alleviated, and can solve the excessive problem of the existing deadweight of present steel core concrete column; Simultaneously; Have equally spaced hole owing to add on the vertical rib, after having filled the lightweight steel fibrous concrete, the concrete of two sides of stiffening rib all can be brought into play the shearing resistance effect; Be mounted in the residing stress state of concrete in the steel plate hole; Its compressive strength is improved, improved the steel pipe and the hypodynamic problem of concrete binding of present steel core concrete column greatly, also improved the globality of structure simultaneously.
Above embodiment only is a preferred embodiment of the utility model; The utility model is not limited to the foregoing description; Any simple modification that the characteristic of every technical scheme according to the utility model is done, increase or equivalence change, and all still belong in the protection domain of the utility model.
