Abstract
The invention discloses a hole-type steel tube concrete pier stud, which comprises a pier stud body, wherein the pier stud body comprises a steel tube, an inner-packed concrete layer and an outer-packed concrete layer; the inner-packed concrete layer is filled in the inner cavity of the steel tube; the outer-packed concrete layer is poured around the steel tube; and the inner-packed concrete layer, the steel tube and the outer-packed concrete layer are connected into a whole by through holes arranged in the tube wall of the steel tube. Therefore, the hole-type steel tube concrete pier stud has a better load bearing performance and is convenient to construct, complex reinforcement processes are avoided, and the problems of corrosion prevention and internal disengaging of the steel tube concrete are effectively solved.
Description
Technical field
The present invention relates to a kind of combining structure pier stud, especially a kind of with the steel-mixed pier stud of porous steel pipe as the central steel skeleton.
Background technology
At present, steel commonly used-mix pier stud is generally fluid concrete formation in steel pipe.This steel-mix pier stud to have the following advantages: 1, steel pipe has improved concrete fragility to concrete effect of contraction, has greatly improved concrete strength; 2, fill in the inner chamber of steel pipe in the concrete, delayed the cripling of steel pipe effectively.Therefore, since its excellent stress performance, this type steel-mix pier stud to be widely used in engineering practice.But this steel-mix limitation below the pier stud existence: 1, the outer wall of steel pipe is exposed in the air, the easy corrosion; It is stressed thereby influence, and therefore, need consider the antirust of steel pipe in the engineering practice; In general, the antirust processing mode that cost is low, its durability is relatively poor; And effect rust-proofing method preferably, cost is higher, at present; Outer wall of steel pipe corrosion protection method commonly used is that (concrete itself is alkalescence at the outside mixed dirt bed of outer wall of steel pipe cast formation; The steel pipe external wrapping concrete is had antirust function to steel), still, outer wall of steel pipe is smooth usually; Concrete is directly built in the steel pipe outside and is come off easily, does not have antirust effect.In the actual engineering, normally, make outer wall of steel pipe coarse, carry out the cast of external wrapping concrete layer again, connect into integral body to guarantee external wrapping concrete layer and original encased structures earlier in modes such as steel pipe outside welding steel mesh reinforcement or pegs.But the mode of welding steel mesh reinforcement or peg is had relatively high expectations to solder technology, and its welding job amount is huge.If steel pipe walls is thinner, steel pipe walls is burnt phenomenon in the time of possibly having welding; 2, there is shrinkage phenomenon in the steel pipe concrete filled, and there is inner possibility of coming to nothing in concrete filled steel tube, and can influence the concrete filled steel tube globality.
Summary of the invention
The present invention is directed to the deficiency of prior art, a kind of porous concrete filled steel tube pier stud is provided, it has load-carrying properties preferably, and has avoided numerous and diverse arrangement of reinforcement operation, easy construction; Anticorrosion and the inside that the has solved concrete filled steel tube effectively problem of coming to nothing.
For realizing above technical purpose, the present invention will take following technical scheme:
A kind of porous concrete filled steel tube pier stud comprises the pier stud body, and this pier stud body comprises steel pipe, interior bag layer of concrete and external wrapping concrete layer; Interior bag concrete is filled in the inner chamber of steel pipe, and external wrapping concrete is cast in the periphery of steel pipe, and the through hole of being offered on said interior bag layer of concrete, steel pipe and the tube wall of external wrapping concrete layer through steel pipe links into an integrated entity.
The rectangular array of said through hole evenly distributes or is and is dislocatedly distributed.
Rounded or the rectangle setting in the cross section of said pier stud body.
The through hole of being offered on the tube wall of said steel pipe is circular port or square opening.
According to above technical scheme, can realize following beneficial effect:
Porous concrete filled steel tube pillarwork proposed by the invention still remains with the stress performance advantage of encased structures itself.External wrapping concrete and concrete filled are poured into a mould simultaneously, connect as a wholely through the steel pipe walls hole, do not exist external wrapping concrete to be connected not firm with steel pipe and obscission has good antirust function to steel.Simultaneously, although also there is contraction in inner concrete, is connected to integral body with external wrapping concrete and has limited its contraction and come to nothing.Use the porous steel pipe and substitute reinforcing bar, itself have load-carrying properties preferably, and avoided numerous and diverse arrangement of reinforcement, easy construction.
So with respect to prior art, the present invention has the following advantages:
The one, good integrity.External wrapping concrete and concrete filled are connected to integral body through porous steel pipe tube wall hole, can play steel pipe antirust with the prevention steel pipe inner concrete phenomenon of coming to nothing.
The 2nd, stress performance is superior.The porous encased structures possesses the stressed advantage of concrete filled steel tube, and steel pipe and concrete retrain each other, improves the holistic resistant behavior of structure.
The 3rd, contact point structure is simple, connects reliable.The cross member reinforcing bar can directly intert in the through hole of porous steel pipe tube wall, can build with porous concrete filled steel tube pier stud to be integral body.
The 4th, simple structure, construction is convenient.The processing of porous steel pipe only needs on existing steel pipe processing mode, to increase the perforate operation, just can produce in batches.And the porous steel pipe substitutes arrangement of reinforcement, has also avoided a large amount of numerous and diverse reinforcing bar bindings and welding.And outsourcing and concrete filled only need one-time-concreting just plastic.

The specific embodiment
Accompanying drawing discloses the structural representation of preferred embodiment involved in the present invention without limitation; Below will combine accompanying drawing that technical scheme of the present invention at length is described.
Shown in Fig. 1 to 7, porous concrete filled steel tube pier stud of the present invention comprises the pier stud body, and this pier stud body comprises steel pipe, interior bag layer of concrete and external wrapping concrete layer; Interior bag concrete is filled in the inner chamber of steel pipe, and external wrapping concrete is cast in the periphery of steel pipe, and the through hole of being offered on said interior bag layer of concrete, steel pipe and the tube wall of external wrapping concrete layer through steel pipe links into an integrated entity.The rectangular array of said through hole evenly distributes (like Fig. 4, Fig. 6) or is be dislocatedly distributed (like Fig. 5, Fig. 7).Cross section of said pier stud body rounded (as shown in Figure 1) or rectangle (as shown in Figure 2) are provided with.The through hole of being offered on the tube wall of said steel pipe is circular port (like Fig. 4, Fig. 5) or square opening (like Fig. 6, Fig. 7).
When construction, at first frame founds good pier stud external mold, with porous steel pipe installation in position, concreting then.For position of joints, can intert in through hole through horizontal steel bar, form effectively connection.Can intert reinforcing bar in the through hole, be used for the connection of building of transverse member.
