Abstract
The utility model discloses a compound steel pipe concrete pile with a pull rod. A circular steel pipe is arranged inside a rectangular steel pipe; a plurality of rectangular holes are formed in the walls of the rectangular steel pipe and the circular steel pipe at certain intervals in the height direction; a steel pull rod is formed from a flat steel or a steel plate; the steel pull rod penetrates through the rectangular holes and is connected with the rectangular steel pipe at the outer side through plug welding; and then concrete is grouted inside the two layers of steel pipes to form the compound steel pipe concrete pile with the pull rod. The compound steel pipe concrete pile with the pull rod is high in bearing capability, good in plasticity and toughness, excellent in fire resistance, simple in node structure and the like.
Description
Technical field
The utility model relates to the steel core concrete column field of mainly bearing vertical load.
Background technology
At present, concrete filled steel tube mainly is used for making the post of bearing vertical load.Concrete-filled circular steel tube column is because the effect of contraction of round steel pipe, has advantages such as bearing capacity height, plasticity and good toughness, fire resistance be better, but the bean column node complex structure, and need carry out flameproof protection, guarantee that it reaches the fire endurance of regulation.Rectangular steel-tube concrete column have plasticity and good toughness, fire resistance better, advantage such as bean column node simple structure; But because rectangular steel pipe is less to the concrete effect of contraction in inside, bearing capacity improves few with respect to the reinforced concrete post of identical reinforcement ratio.Therefore, need a kind of supporting capacity height, plasticity and good toughness, good, the simple steel core concrete column of joint structure of fire resistance.
Summary of the invention
In order to overcome the deficiency of existing single steel core concrete column, the utility model provides a kind of compound steel core concrete column with pull bar, and this post has advantages such as supporting capacity height, plasticity and good toughness, fire resistance is good, joint structure is simple.
The technical scheme of the utility model is: at rectangular steel pipe set inside round steel pipe; Short transverse whenever is provided with a plurality of rectangular openings at a distance from a segment distance in the tube wall upper edge of rectangular steel pipe and round steel pipe; Make reinforcing pull rod with band steel or steel plate, reinforcing pull rod is passed rectangular opening, and link together through plug welding with the rectangular steel pipe in the outside; Concrete perfusion all in the inside of two-layer steel pipe then forms the compound steel core concrete column of band pull bar.Because the good effect of contraction of inner circular steel pipe; The inner concrete bearing capacity of round steel pipe is improved greatly; Because the drawknot effect of reinforcing pull rod, rectangular steel pipe obtains certain raising to concrete effect of contraction, and its inner concrete bearing capacity and ductility obtain certain raising; Therefore, the bearing capacity of this compound steel core concrete column is higher.Because the inner circular steel pipe receives the protection of outer concrete, programming rate is slow in fire process, and bearing capacity reduces slowly, therefore has good fire resistance.Simultaneously, because the outside is a rectangular steel pipe, so the bean column node simple structure.
The utility model has improved rectangular steel pipe to the concrete effect of contraction in inside, has improved the bearing capacity of post, and simultaneously, because outside concrete protective effect, round steel pipe and inner concrete bearing capacity reduce in fire process slowly, and fire resistance is good.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the front view of the utility model;
Fig. 2 is the constructional drawing of the utility model rectangular steel pipe;
Fig. 3 is the constructional drawing of the utility model round steel pipe.
Among the figure: 1-rectangular steel pipe, 2-round steel pipe, 3-reinforcing pull rod, 4-concrete, 5-rectangular opening.
The specific embodiment
Among Fig. 1; At rectangular steel pipe 1 set inside round steel pipe 2; At rectangular steel pipe 1 and round steel pipe 2 set inside reinforcing pull rods 3, and be connected through plug welding, be used to retrain the distortion of rectangular steel pipe with rectangular steel pipe; Improve rectangular steel pipe to the concrete effect of contraction in inside, at last in the inside of rectangular steel pipe 1 and round steel pipe 2 all concrete perfusion 4 form coupled columns.
Among Fig. 2, short transverse whenever is provided with a plurality of rectangular openings 5 at a distance from a segment distance in the tube wall upper edge of rectangular steel pipe 1.
Among Fig. 3, short transverse whenever is provided with a plurality of rectangular openings 5 at a distance from a segment distance in the tube wall upper edge of round steel pipe 2.
