The utility model discloses the technological solution that adopts is a reinforcing bar concrete dysmorphism post of built -in CFRP pipe, including reinforcing bar, reinforcing bar, CFRP pipe and concrete, the reinforcing bar form and be located special -shaped post limb position by steel sheet welding, the reinforcing bar include the stirrup and indulge the muscle, the stirrup enclose into the skeleton, vertical muscle setting in special -shaped column section bight, the center of the crossing department of special -shaped post limb be provided with the CFRP pipe, special -shaped post intussuseption be filled with the concrete. Special -shaped column section form be T or L or cross.

Description

A kind of steel reinforced concrete hetermorphiscal column of inner CFRP tubular circular

Technical field

The utility model belongs to technical field of civil engineering, particularly relates to a kind of steel reinforced concrete hetermorphiscal column of inner CFRP tubular circular.

Background technology

Along with the development of builing industry, people not only have certain requirement for building structure, and also have certain requirement to the level of comfort of living, common reinforced concrete square columns sectional dimension is often greater than the thickness of body of wall, occupy the interior space, also have impact on the attractive in appearance of building, obviously traditional frame column structure can not meet the demand of people, and special-shaped column structure is a kind of new structure that grew up in recent years simultaneously.Through the research of domestic and international expert, scholar, steel concrete deformed pile structure theoretical system basically forms.The provinces and cities such as such as Tianjin, Shenyang, Guangdong, Shanxi have completed writing of local code, and and guide in engineering practice, building area reaches tens million of square metres.

Along with the building of super highrise building and large span was constantly occurring and developing in recent years, the size of post net increases, and the load that single-column is born increases.Adopt the building of reinforced concrete structure must add the section area of huge pillar, so easy formation, to the disadvantageous short column of antidetonation, also takies usable floor area.If now adopt Structure System with Special-shaped Column, be subject to the effective width restriction of column section, will inevitably thickness be increased, thus the advantage of hetermorphiscal column cannot embody.Therefore, in many highrise buildings, the application of shaped rc columns is often restricted.In steel concrete, add reinforcing bar, reinforcing bar part and reinforced concrete enveloped form an entirety and the effect of shared external load.When not increasing structural section area, the bearing capacity of post can be improved, improves the anti-seismic performance of structure simultaneously.

FRP has been widely used in the fields such as Aero-Space, and its superiority gets the nod already.But because its price is higher so do not use on a large scale in field of civil engineering.In the last few years, along with the raising of the level of production and the reduction of cost, this material obtained popularization energetically in builing industry.At present, CFRP is widely used in engineering, in the maintenance as bridge strengthening, maintenance and all kinds of industrial and civil architecture.In engineering, structure is because of time integral, produces structural deterioration.The method of adopt carbon fiber structural to reinforce, keeping in repair is the method that modern project technology is commonly used.Its high-strength light, tensile property is high, excellent in durability, antifatigue, and the advantages such as corrosion resistance and good are fully utilized.

Summary of the invention

The defect that the utility model exists to overcome prior art, the purpose of this utility model is to provide a kind of steel reinforced concrete hetermorphiscal column of inner CFRP tubular circular.

The technical solution that the utility model adopts is a kind of steel reinforced concrete hetermorphiscal column of inner CFRP tubular circular, comprise reinforcing bar, reinforcing bar, CFRP pipe and concrete, described reinforcing bar is formed by Plate Welding and is positioned at hetermorphiscal column post limb position, described reinforcing bar comprises stirrup and vertical muscle, described stirrup surrounds skeleton, described vertical muscle is arranged on hetermorphiscal column corners of cross section, and the center of described hetermorphiscal column post limb intersection is provided with CFRP pipe, is filled with concrete in described hetermorphiscal column.The wall thickness of described CFRP pipe is 3 ~ 6 layers of CFRP yardage roll, and individual fiber thickness is 0.167mm.

Described hetermorphiscal column section form is T or L or cross.

Compared with prior art, the beneficial effect that the utility model has is:

1. make full use of the characteristic of CFRP material high-strength light, decrease the use amount of steel, the deadweight of the component alleviated;

Concrete in 2.CFRP pipe is in three-phase pressured state, improves the supporting capacity of post, has saved space;

3. be distributed in hetermorphiscal column post limb by the reinforcing bar of Plate Welding, improve the ductility of post, improve bearing capacity, be conducive to seismic design.
