Abstract
The invention relates to a polyvinyl chloride (PVC) pipe reinforced concrete and steel pipe concrete laminated member which belongs to a civil engineering member. A PVC pipe is adopted in an outer layer of the member, a steel pipe is adopted in an inner layer, concrete is filled in the inner steel pipe, reinforced concrete is filled between the outer PVC pipe and the inner steel pipe, end faces of the outer PVC pipe reinforced concrete and the inner steel pipe concrete are level, and geometric centers of sections of the outer PVC pipe and the inner steel pipe are coincide. The outer PVC pipe and the inner steel pipe respectively adopt section forms of circle, square, rectangle, polygon, round end, ellipse and the like. The member has the advantages of common steel pipe concrete laminated members, can improve the bearing capacity and the corrosion resistance while increasing small dead weight, and can be applied to large-diameter pillars in bridge piers and buildings and other related towering structures or pillar members.
Description
Technical field
The present invention relates to a kind of civil engineering member, particularly relate to a kind of pvc pipe steel concrete-steel tube concrete superposed member.
Background technology
Conventional steel tube concrete superposed member is to be formed by the concrete filled steel tube at middle part, cross section and the outer reinforced concrete sandwich of steel pipe; This class formation can effectively improve the supporting capacity of member, ductility and refractory ability, and reduce the member section size; Begun to use in, the highrise building many at some.Yet the member skin is a steel concrete, and the corrosion resistance of member is a big problem, and steel concrete places air or wet environment that carbonization and alkali-aggregate reaction can take place for a long time, causes reinforcing bar and steel pipe generation corrosion.
Summary of the invention
The object of the present invention is to provide a kind of pvc pipe steel concrete-steel tube concrete superposed member, improved structure, can effectively suppress the carbonization and the alkali-aggregate reaction of operational phase steel concrete, and then improve structural life-time in the operability of construction stage; Because pvc pipe is lighter, dead load increases less simultaneously.
The objective of the invention is to be achieved through the following technical solutions:
Pvc pipe steel concrete-steel tube concrete superposed member, this member comprise inside and outside two-layer pipe, and interior pipe adopts steel pipe, and outer tube adopts pvc pipe, and fill concrete in the steel pipe is a steel concrete in the two pipe clamp layers, and steel concrete is made of vertical muscle, stirrup and concrete.
Described pvc pipe steel concrete-steel tube concrete superposed member, its outer pvc pipe steel concrete is equal with interior concrete filled steel tube end face, and the geometric centroid of pvc pipe, steel concrete and interior steel tube section overlaps.
Described pvc pipe steel concrete-steel tube concrete superposed member, its outer pvc pipe and interior steel pipe are circular cross-section; Or outer pvc pipe is that circular cross-section, interior steel pipe are the square-section; Or outer pvc pipe is that square-section, interior steel pipe are circular cross-section; Or outer pvc pipe and interior steel pipe are the square-section; Or outer pvc pipe and interior steel pipe are the square-section; Or outer pvc pipe is that circular cross-section, interior steel pipe are the square-section; Or outer pvc pipe is that square-section, interior steel pipe are the square-section; Or outer pvc pipe and interior steel pipe are hexagonal cross-section; Or outer pvc pipe and interior steel pipe are octagonal cross-section; Or outer pvc pipe and interior steel pipe are the nose circle tee section; Or outer pvc pipe and interior steel pipe are elliptic cross-section.
Advantage of the present invention and effect are:
The template action of outer pvc pipe has been improved structure in the operability of construction stage, and can effectively suppress the carbonization and the alkali-aggregate reaction of operational phase steel concrete, and then improves structural life-time; The pvc pipe material itself has determined structure to have favorable environment protection energy and corrosion resistance in operational phase; Because pvc pipe is lighter, dead load increases less simultaneously.
Outer pvc pipe of the present invention adopts the pvc pipe of market purchase or the pvc pipe in customization 2-30mm different tube diameters and cross section, the reinforcing bar of steel concrete can adopt plain bars or high tensile reinforcement, concrete can be that ordinary concrete or compressive strength are high-strength concrete or the self-compacting concrete of 80-120MPa, interior steel pipe can adopt regular tenacity steel or the yield strength high-strength steel more than 550Mpa, and can to adopt the ratio of steel pipe external diameter or the outer length of side and thickness of steel pipe be the thin-wall steel tube of 40-150.This new structure can be applied to major diameter post and other relevant towering structure or its post member in bridge pier, the building, especially in the environment that corrosion resistance is had relatively high expectations.
