Abstract
The utility model provides a sea sand concrete structure with nonrust reinforcing bar, including extra large sand concrete structure and set up nonrust reinforcing bar or the nonrust steel wire in extra large sand concrete structure. The chlorion that utilizes the superior corrosion resisting property of nonrust reinforcing bar to resist in the extra large sand corrodes, consequently need not desalinate and desalination extra large sand, also need not adopt artificial safeguard measures such as isolation layer to the reinforcing bar, makes extra large sand concrete can directly be arranged in building structure to make and promote extra large sand concrete enable on a large scale, saved a large amount of manual works and economic cost simultaneously.
Description
Technical field
This utility model relates to a kind of marine sand concrete structure with stainless reinforcing bar.
Background technology
Flourish along with China's civil engineering construction, concrete amount increases rapidly the most therewith.River sand resource as concrete fine aggregate is the deficientest, and to ecological environmenies such as the riverbed of China, soil and groundwaters, the exhaustive exploitation of fluvial sand is caused the biggest destruction.And in fact as the replacement scheme of fluvial sand, use marine sand concrete can alleviate the difficult problem that river sand resource is not enough in coastal area, solve the inconvenience of long-range sand material Mining Transport, be conducive to preserving the ecological environment, it is achieved the sustainable development of building industry.But, due to the chloride ion meeting corrosion reinforcing bar in sea sand, and existing sea sand desalting desalting technology can expend a large amount of economy and human cost.
Although used FRP pipe or FRP muscle to replace the solution of normal carbon reinforcing bar to solve etching problem in marine sand concrete in the past, but FRP material can only tension and cannot pressurized and being cut, and the fragility of FRP material is bigger, its linear expansion coefficient and concrete the most difference, these all have impact on cooperation performance therebetween, is also unfavorable for stability and the anti-seismic performance of component simultaneously.
Used in the past regular reinforcement or steel pipe are carried out isolation processing (such as smearing epoxy resin) although etc. artificial protective measure can prevent the sea sand corrosion to steel to a certain extent; but the complicated construction technique of these measures; it is unfavorable for spread, and destroys the interfacial bond property between steel and concrete to a certain extent.
Summary of the invention
The problems referred to above are improved by this utility model, i.e. the technical problems to be solved in the utility model is: cannot meet the requirement of anticorrosion and mechanical index in existing element structure simultaneously.
Specific embodiments of the present utility model is: a kind of marine sand concrete structure with stainless reinforcing bar, the stainless reinforcing bar including marine sand concrete structure and being arranged in marine sand concrete structure or stainless steel silk.
Further, described stainless reinforcing bar or stainless steel silk use one or more materials in Austenitic rustless steel, ferrite type rustless steel, martensite type rustless steel and all stainless steels of austenite ferrite type to make.
Further, described marine sand concrete structure is that the natural sea sand processed without desalinating desalting forms as fine aggregate mixing.
Further, described marine sand concrete structural section is rectangle or circle.
Further, in described marine sand concrete structure, it is provided with crisscross stainless reinforcing bar, for colligation or weld between stainless reinforcing bar and the longitudinally disposed stainless reinforcing bar of described horizontally set.
Further, described longitudinally disposed stainless reinforcing bar is provided with the nose bar stainless reinforcing bar for location horizontally set.
Compared with prior art; this utility model has the advantages that the decay resistance utilizing stainless reinforcing bar superior is to the Chloride Attack resisting in sea sand; therefore need not sea sand is desalinated and desalting processing; also without reinforcing bar being used the artificial protective measures such as sealing coat; make marine sand concrete be used directly in building structure, thus save substantial amounts of artificial and Financial cost.
Stainless reinforcing bar except every mechanical performance index such as intensity and ductility etc. be above or the most defeated in regular reinforcement in addition to, it also has the linear expansion coefficient close with regular reinforcement and interfacial bond property, the overall structure making the present invention has good mechanical property and superior endurance quality concurrently, it is adaptable to the works in coastal high corrosion area requires longer Important building with some to service life.
The new structural systen of the invention can make marine sand concrete be directly used in all composition components of monolithic architecture structure, the floor that especially concrete amount is most, the reinforced concrete construction technique of existing maturation can also being used, being possibly realized so that promoting marine sand concrete on a large scale.
The utility model is described in more detail with detailed description of the invention below in conjunction with the accompanying drawings.

Detailed description of the invention
As shown in Fig. 1～10, the detailed description of the invention of the present invention is: a kind of structural elements collectively constituted by stainless reinforcing bar 2 and marine sand concrete structure 1, and the structure of molding includes beam, post and floor, and the integral structural system being made up of these structural elements.During construction, by stainless reinforcing bar embedment marine sand concrete, the two common stress resists external load.
Use stainless reinforcing bar to make the longitudinal reinforcement needed for structural elements and transverse steel when being embodied as, rustless steel is indulged muscle and horizontal bar colligation again or is welded into framework of steel reinforcement, then at the outer formwork of framework of steel reinforcement, and pour marine sand concrete, ensure that concrete vibrating is closely knit simultaneously.Marine sand concrete uses the natural sea sand processed without desalinating desalting to form as the uniform mixing of fine aggregate.Stainless reinforcing bar can use one or more materials in all stainless steels such as Austenitic rustless steel, ferrite type rustless steel, martensite type rustless steel and austenite ferrite type rustless steel to be made.
Additionally, be provided with the nose bar stainless reinforcing bar for location horizontally set for the ease of positioning described longitudinally disposed stainless reinforcing bar, it is beneficial to operation when installing.
The foregoing is only preferred embodiment of the present utility model, all impartial changes done according to this utility model claim and modification, all should belong to covering scope of the present utility model.
