Abstract
An I-shaped FRP (fiber reinforced plastic) section-steel pipe-concrete column combination belongs to a long strip-shaped component for load-bearing in a fixed building and comprises a rectangular, square or circular steel pipe, an I-shaped FRP section and concrete. The I-shaped FRP section is placed in the steel pipe, the concrete is filled between the steel pipe and the I-shaped FRP section, and the section of the I-shaped FRP section-steel pipe-concrete column combination is a rectangular structure, a square structure or a circular structure. Compared with the prior art, the I-shaped FRP section-steel pipe-concrete column combination has the advantages that the size of the section of a column can be reduced under the condition that steel ratio and configuration rate of FRP (fiber reinforced plastics) are reasonably selected, a framework of the steel pipe can be used for temporary support during construction, and construction speed is increased. In addition, ductility of the column is improved by the steel pipe, the steel pipe is favorable for an anti-seismic design for a seismic area, bearing capacity of the column is improved by the aid of the characteristics of light weight and high strength of FRP materials, and service area is increased.
Description
Technical field
The utility model relates to I shape FRP section bar-steel tube-concrete post, particularly relates to by rectangle, square or round steel pipe and is placed on the I shape FRP section bar in the steel pipe and the concrete that is filled between the two constitutes.
Background technology
Because frame construction has advantages such as flexible arrangement, usage space are big, therefore received the extensive concern of engineering.And be generally common reinforced concrete post as the frame column of the main member of frame construction, and promptly tied up reinforcing cage earlier, propped up template again; Last fluid concrete; Make this traditional reinforced concrete post exist long in time limit, difficulty is big, inefficient shortcoming, Chinese utility model patent has provided " a kind of reinforced concrete post " after improving for No. 03248845.9, comprises precast member for reinforcing bar concrete; Reinforcing bar; Reinforced concrete post is made up of polylith steel concrete tubular prefabricated units, longitudinal reinforcement network for location sheet, longitudinal reinforcement, and polylith steel concrete tubular prefabricated units are overlapped into the post mould, and the longitudinal reinforcement network for location sheet that adapts with tubular prefabricated units inner chamber is set between adjacent steel reinforced concrete tubular prefabricated units seam; Longitudinal reinforcement interts in longitudinal reinforcement network for location slice graticule; Serial connection polylith steel concrete tubular prefabricated units, concreting in the superimposed post mould cavity of steel concrete tubular prefabricated units finally becomes reinforced concrete post again.Though the shortcoming that the reinforced concrete post after this improvement has existed when tentatively having overcome conventional steel reinforced concrete column production can not satisfy the increasingly high requirement of high-rise building to the use concrete structure.For this reason, people develop novel concrete structure again, and for example United States Patent (USP) provides for No. 3051161 uses the concrete filling steel pipe, to increase the encased structures technical scheme of compressive strength.China's utility model patent has provided " a kind of novel steel tube concrete column " for No. 99236299.7; Wherein being used for the concrete steel pipe of filling is the special-shaped thin wall steel pipe; Be provided with binding bar on each limit of special-shaped thin wall steel pipe; Though this steel core concrete column has solved the single problem of existing concrete filled steel tube post shapes, but still exist for the local buckling that prevents thin-wall steel tube binding bar need be set, construction has the shortcoming of inconvenience more.And I shape FRP section bar-steel tube-concrete post is to utilize the I shape FRP section bar that is placed on steel duct to replace core concrete to bear structural load; Reduced the lateral pressure of core concrete to steel pipe walls; And binding bar need be set; And can reduce the sectional dimension of member, the appearance of similar techniques scheme is not then arranged in document as yet.
Summary of the invention
The purpose of the utility model is because the number of plies of building is more and more, depth of building is increasingly high to current; The intensity of institute's materials used is increasingly high; Such as Materials with High Strength FRP, high-strength concrete etc.; And the ductility of high-strength concrete is relatively poor, and FRP belongs to the linear elasticity material, with the anti-seismic performance that influences structure.In conjunction with the theory of the own concrete filled steel tube of knowing, the structure of existing steel core concrete column is improved, and provided novel I shape FRP section bar-steel tube-concrete post.This novel I shape FRP section bar-steel tube-concrete post; Solve the shortcoming of existing square, rectangle or round steel pipe concrete column; Make full use of the intensity of FRP material; Have the bearing capacity height, rigidity is big, in light weight, plasticity, good toughness, characteristics such as shock resistance and anti-fatigue performance are good, anti-seismic performance is good.
The technical scheme that the utility model provides is: this novel I shape FRP section bar-steel tube-concrete post is by rectangle, square or round steel pipe and be placed on the I shape FRP section bar in the steel pipe and the concrete that is filled between the two constitutes; Be characterized in the coupled column of described I shape FRP section bar-steel tube-concrete post for forming by FRP, steel pipe and three kinds of different materials of concrete; Be I shape FRP section bar-steel tube-concrete coupled column, wherein the cross sectional shape of I shape FRP section bar-steel tube-concrete post is rectangular configuration, square structure or circular configuration.
Used steel pipe can be welded by steel plate in the I shape FRP section bar-steel tube-concrete post described in the utility model, can be that rectangle also can be square or circle, built-in I shape FRP section bar.The configuration of steel pipe is by existing steel and the design of concrete combined structure tecnical regulations.
Compared with prior art, the beneficial effect of the utility model is:
(1) behind choose reasonable steel pipe, FRP Disposing rate, can reduce the sectional dimension of post, steel pipe skeleton can provide interim support when construction, quicken construction;
(2) because the existence of steel pipe has improved the ductility of post, improve the bearing capacity of post, be beneficial to the earthquake zone seismic design.
(3) I shape FRP section bar-steel tube-concrete post can reduce the weight of building in use, increases effective usable floor area.
