Abstract
The utility model discloses a concrete column with a steel pipe, which comprises a steel pipe and concrete poured into the inside of the steel pipe. The concrete column with the steel pipe is characterized in that the section of the steel pipe is a polygon with at least five edges. Moreover, an inner supporting pipe is arranged in the steel pipe, and the concrete is poured between the steel pipe and the inner supporting pipe. Because the steel pipe adopts a steel pipe of which the section is octagonal, the inner supporting pipe is arranged in the steel pipe. Under the precondition of meeting the stress, the concrete only needs to be poured between the steel pipe and the inner supporting pipe. A water blanking pipe can pass through a hollow part, the sectional dimension and the self weight of the column are also decreased, and the use quantity of the concrete is saved, thereby lowering the construction cost and achieving favorable architectural and economic effects.
Description
Technical field
The utility model belongs to technical field of structural engineering, is specifically related to a kind of steel core concrete column.
Background technology
Because strong concrete has intensity height, distortion characteristics such as little, impervious corrosion resistance is good, can improve the supporting capacity of concrete structure and member significantly, reduce concrete structure deadweight, reduce the sectional dimension of structural element, therefore at highrise building, in order to reduce the size in cylinder cross section, and use strong concrete widely in the large-span structure.But the ductility of strong concrete is relatively poor, influences the shock resistance of structure.In order to address this problem, adopted encased structures on the engineering, because steel pipe provides effect of contraction to concrete, has produced the sleeve effect, so the whole anti-seismic performance of the plastic displacement of encased structures, the energy dissipation capacity that increases structure, raising building.At present, the cross section of common steel core concrete column is circle or rectangle, when the house number of plies of building is got over for a long time, the load that post is born will strengthen, need the sectional dimension of post just big more, for the sectional dimension that reduces post just needs thicker steel pipe to offer the enough supports of concrete, so need the special processing of factory, must improve construction costs, improve difficulty of construction.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of steel core concrete column that had not only satisfied force request but also had building and economic effect.
The technical scheme that its technical problem that solves the utility model adopts is:
Steel core concrete column comprises steel pipe and the inner concrete that waters, and it is characterized in that: described steel tube section is the polygon at least five limits, and is provided with interior stay pipe in the steel pipe, and pouring has concrete between described steel pipe and interior stay pipe.
Further, steel tube section is an octagon, and the cross section of interior stay pipe is corresponding quadrangle.
Further, be provided with gusset plate between described steel pipe and interior stay pipe.
The beneficial effects of the utility model are: because steel pipe of the present utility model has adopted the cross section is octagonal steel pipe, is provided with interior stay pipe in the steel pipe.Satisfying under the stressed prerequisite, only needing placing of concrete between steel pipe and interior stay pipe.Not only cavity can pass through leader, and reduced post sectional dimension and deadweight, saved concrete amount, thereby reduced construction costs, reached good building and economic effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a cross-sectional view of the present utility model.
The specific embodiment
With reference to Fig. 1, the utility model discloses a kind of steel core concrete column, comprise the concrete of steel pipe 1 and inner pouring, steel pipe 1 cross section be the polygon of hexagon at least, and is provided with interior stay pipe 2 in the steel pipe 1,2 pourings of steel pipe 1 and interior stay pipe have concrete.
As shown in the figure, steel pipe 1 cross section is an octagon in the present embodiment, and the cross section of interior stay pipe 2 is corresponding rectangle.2 of stay pipes have watered concrete in octagon steel pipe 1 and rectangle.Further, during for placing of concrete in stay pipe 2 can keep stable and improve the force intensity that is subjected to of mechanism, welded ten gusset plates 3 at steel pipe 1 and 2 of interior stay pipes.In order to make steel pipe 1 and interior stay pipe 2 stressed even, ten gusset plates 3 are symmetrically distributed along steel pipe 1 centre section.
Above-mentionedly just preferred embodiments more of the present utility model are illustrated and describe, but embodiment of the present utility model is not restricted to the described embodiments, such as: steel tube section can be hexagon, and interior stay pipe is that the cross section is corresponding quadrangle or circle; Steel tube section also can be decagon, and interior stay pipe is that the cross section is corresponding circle, quadrangle or hexagon.As long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
