Abstract
The utility model provides an adopt steel pipe concrete coincide post component of active powder concrete outsourcing, belongs to building material technical field, constitutes integral coincide post jointly by steel pipe, core concrete, stirrup and active powder concrete, and the stirrup cover is put in the outside of steel pipe, is equipped with in the four corners of stirrup and indulges the muscle, and active powder concrete placement is between steel pipe outer wall and stirrup. The utility model discloses novel structure has combined the advantage of traditional steel pipe concrete coincide post and active powder concrete, and the theory of operation is clear, improves bearing capacity, the ductility of traditional steel pipe concrete coincide post, anti crack, corrosion resistance's ability greatly, and the cost is reasonable, is fit for being used for high level, superelevation layer foundation and longspan bridge pier, off -shore structure etc..
Description
Technical field
The utility model belongs to building material technical field, relates to a kind of concrete filled steel tubular member, specifically relates to a kind of steel tube concrete superposed column component adopting RPC outsourcing.
Background technology
As everyone knows, concrete compressive strength is high, but bending resistance is very weak; And the bending resistance of steel, particularly shaped steel is strong, there is good elastoplasticity, but when pressurized easy unstability and lose axial compression resistance ability.And steel tube concrete superposed column structurally can by the advantages of the two together, can make concrete be in side loaded state, its compressive strength can significantly improve.Simultaneously due to concrete existence, improve the rigidity of steel pipe, both play a role jointly, thus greatly increase supporting capacity.But traditional steel tube concrete superposed column also has the defect of himself, comprise outside crack-resistant performance of concrete bad, durability corrosion resistance is poor is not suitable for off-shore structure, particularly adopts the steel tube concrete superposed column ductility of high-strength concrete and anti-seismic performance also can not be satisfactory.
Utility model content
The defects such as the cracking resistance that the utility model exists for above-mentioned conventional steel concrete superposed column is bad, durability corrosion resistance is poor, the large anti-seismic performance of high strength concrete filled steel tube fragility is bad, a kind of steel tube concrete superposed column component adopting RPC outsourcing is proposed, improve its supporting capacity and ductility, strengthen cracking resistance and corrosion resistance, extend its application life.
The technical solution of the utility model is: the steel tube concrete superposed column component adopting RPC outsourcing, it is characterized in that: jointly form monolithic superposed column by steel pipe, core concrete, stirrup and RPC, described stirrup is nested with the outside at described steel pipe, be provided with vertical muscle in the corner of described stirrup, described RPC is cast between described outer wall of steel pipe and described stirrup.
Described steel pipe can be round steel pipe, square steel pipe, rectangular steel pipe or polygonal steel pipe.
Described core concrete is ordinary concrete.
Described stirrup shape can be circular, square, rectangle or polygon.
The beneficial effects of the utility model are: the steel tube concrete superposed column component of the employing RPC outsourcing that the utility model provides, novel structure, combine the advantage of conventional steel concrete superposed column and RPC, operating principle is clear, greatly improve the ability of the bearing capacity of conventional steel concrete superposed column, ductility, cracking resistance seam, corrosion resistance, cost is reasonable, is suitable for high level, Super High foundation and Longspan Bridge bridge pier, off-shore structure etc.
Accompanying drawing explanation
Fig. 1 is the utility model surface structure schematic diagram.
Fig. 2 is the utility model A-A sectional drawing.
In figure: RPC 1, core concrete 2, steel pipe 3, stirrup 4, vertical muscle 5.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1-2, adopt the steel tube concrete superposed column component of RPC outsourcing, monolithic superposed column is jointly formed by steel pipe 3, core concrete 2, stirrup 4 and RPC 1, stirrup 4 is nested with the outside at steel pipe 3, be provided with vertical muscle 5 in the corner of stirrup 4, RPC 1 is cast between steel pipe 3 outer wall and stirrup 4.
As shown in Figure 1-2, adopt the detailed description of the invention of the steel tube concrete superposed column component of RPC outsourcing as follows: first in steel pipe 3(round steel pipe, square steel pipe, rectangular steel pipe or polygonal steel pipe) interior filling core concrete 2(ordinary concrete), stirrup 4 is overlapped outside steel pipe 3, stirrup 4 four angles arrange vertical muscle 5, stirrup 4 is wrapped by one deck RPC 1 outside steel pipe 3, add that the bearing capacity that RPC is splendid and corrosion resistance can improve bearing capacity and the corrosion resistance of steel core concrete column greatly because both sides inside and outside steel pipe 3 have concrete to wrap up.Adopt RPC 1 outside the factor steel pipe of consideration economic aspect, inside steel pipe, adopt core concrete 2; Core concrete 2, steel pipe 3, vertical muscle 5, outer active powder concrete 1 bear post external load simultaneously, and the cross section of whole post can be circular, square, rectangle or polygon, forms new steel tube-concrete composite structure.
The steel tube concrete superposed column component of the employing RPC outsourcing that the utility model provides, novel structure, combine the advantage of conventional steel concrete superposed column and RPC, operating principle is clear, greatly improve the ability of the bearing capacity of conventional steel concrete superposed column, ductility, cracking resistance seam, corrosion resistance, cost is reasonable, is suitable for high level, Super High foundation and Longspan Bridge bridge pier, off-shore structure etc.
