Abstract
The utility model provides a carbon fibre reinforced plastic steel skeleton-steel pipe-encased concrete reinforced column, which relates to a building component form. The reinforced column comprises a carbon fibre reinforced plastic fibre fabric, a steel skeleton and a steel pipe-encased concrete core column. The steel skeleton is positioned at the four corners of the steel pipe-encased concrete core column; the carbon fibre reinforced plastic fibre fabric is adhibited with the outside of the steel skeleton; the carbon fibre reinforced plastic fibre fabric is integrally adhibited with the steel skeleton and the steel pipe-encased concrete core column. The reinforced column is reinforced by a reinforcing method adopted after the steel pipe-encased concrete core column is damaged, and compared with a reinforced structure simply adopting angle irons, the reinforced structure can better improve the bearing capability and extendability of the steel pipe-encased concrete core column.
Description
Technical field
The utility model relates to a kind of building unit form, particularly relates to a kind of structure of carbon fiber-reinforced plastic steel reinforced-steel tube concrete combination column.
Background technology
Steel tube concrete core pole is meant a kind of structural element that concrete filled steel tube is set in the inboard of reinforced concrete post.This member has produced the sleeve effect because steel pipe provides effect of contraction to the concrete of core space, so, can improve significantly post bearing capacity, improve the whole anti-seismic performance of building, its energy dissipation capacity is apparently higher than general reinforced concrete post.This kind post has been applied among many engineerings, often is applied in concrete engineering in the post of which floor high axial compression ratio of bottom of highrise building, and its stress is mainly small eccentric pressure.But remain in following main deficiency: steel tube concrete core pole is during at compression damage, and the reinforced concrete post two parts in the steel core concrete column and the outside may not destroy simultaneously, inside and outside in other words well co-operation.
For this problem, the scholar who has has proposed the notion of boundary volume distributed ratio, that is: " when volume distributed ratio during greater than the boundary volume distributed ratio internal and external parts can co-operation until destruction, otherwise the outside is destroyed prior to inside part ".The proposition of this theory has solved a great problem in steel tube concrete core pole research and the application really, but in some engineering was used, its boundary volume distributed ratio was excessive, was difficult to realize.
Because China is between in the world two main earthquake zones, therefore, earthquake be inevitable.Just have the earthquake on ground such as Taiwan, Japan recent years, though fail to involve the continent, it still is right providing for a rainy day.
Summary of the invention
The purpose of this utility model is to provide a kind of carbon fiber-reinforced plastic steel reinforced-steel tube concrete combination column, this concrete filled steel tube coupled column is after such post destroys, by the consolidation process of reinforcing bar and carbon fibre reinforced plastic (CFRP), thereby improve bearing of component and ductility.
The purpose of this utility model is achieved through the following technical solutions:
Carbon fiber-reinforced plastic steel reinforced-steel tube concrete combination column, this coupled column comprises carbon fibre reinforced plastic fabric, reinforcing bar and steel tube concrete core pole, its described reinforcing bar is positioned at four jiaos of steel tube concrete core pole, the carbon fibre reinforced plastic fabric is pasted on the outside of reinforcing bar, and it is an integral body that carbon fibre reinforced plastic fabric and reinforcing bar, steel tube concrete core pole are pasted.
Aforesaid carbon fiber-reinforced plastic steel reinforced-steel tube concrete combination column, described reinforcing bar can be angle steel, also can be welded by steel plate; The fabric that the carbon fibre reinforced plastic fabric adopts can be unidirectional or two-way, and machine direction and mast axis angle are between 0～90 °.
Advantage of the present utility model and effect are:
The utility model is reinforced after steel tube concrete core pole is damaged, and the structure after the reinforcing can better improve the carrying and the ductility of steel tube concrete core pole than the simple structure that adopts the reinforcement means reinforcing of angle steel.
Description of drawings
Accompanying drawing is the schematic cross-section of the utility model carbon fiber-reinforced plastic steel reinforced-steel tube concrete combination column.
The specific embodiment
With reference to the accompanying drawings the utility model is elaborated.
As shown in the figure, carbon fiber-reinforced plastic steel reinforced-steel tube concrete combination column of the present utility model comprises carbon fibre reinforced plastic fabric 2, reinforcing bar 1, steel tube concrete core pole three parts.Wherein, steel tube concrete core pole comprises the concrete of round steel pipe and its inside and outside portion.Reinforcing bar 1 is positioned at four jiaos of steel tube concrete core poles, and carbon fibre reinforced plastic fabric 2 is positioned at the outside of reinforcing bar, and carbon fibre reinforced plastic is formed whole by stickup and reinforcing bar, steel tube concrete core pole.Reinforcing bar can be an angle steel, also can be welded by steel plate; The fabric that carbon fibre reinforced plastic fabric 2 adopts can be unidirectional or two-way, and machine direction and mast axis angle can be between 0～90 °.
The utility model is to the structure after its reinforcing after steel tube concrete core pole is damaged, its reinforcement means is: when reinforcing steel tube concrete core pole, at the upright reinforcing bar of the outer bogie side frame of steel tube concrete core pole, connect by horizontal batten plate between the reinforcing bar, the spacing of reinforcing bar and steel tube concrete core pole should reduce as far as possible; That is, angle steel (or steel plate is welded) is stood on the Si Jiaochu of post, and connect into integral body by horizontal batten plate.Then, it is flat to use " building slurry " that external surface is touched, and pastes the carbon fibre reinforced plastic fabric in the outside of post at last.
