Abstract
The utility model relates to bending structures in bridges, buildings and other structures, in particular to a fiber reinforced plastic (FRP) outer pack pipe FRP geosynthetic sea sand fiber reinforced concrete bending member which comprises an FRP outer pack pipe, an FRP geosynthetic and a concrete structure, wherein the FRP geosynthetic and the concrete structure are arranged in the FRP outer pack pipe, the FRP geosynthetic is distributed and arranged along the length direction of the FRP outer pack pipe in a dispersed mode, and the FRP geosynthetic is distributed and arranged along the radial direction of an cross section of the FRP outer pack pipe in a dispersed mode. The FRP outer pack pipe FRP geosynthetic sea sand fiber reinforced concrete bending member adds concrete and FRP outer pack pipe to traditional bending members. The FRP outer pack pipe FRP geosynthetic sea sand fiber reinforced concrete bending member has good corrosion resistance, and effectively solves the problem that traditional FRP geosynthetic concrete bending members are poor in shearing resistance and low in ductility.
Description
Technical field
The utility model relates to the flexural member in the structures such as bridge, building, more particularly, relates to a kind of FRP pipe outsourcing FRP muscle material sea sand fibrous concrete flexural member.
Background technology
The beam that in engineering structures fields such as bridge, building, generally uses at present comprises steel concrete (Reinforced concrete, RC) beam and girder steel.These two kinds of beam corrosion resistances are all relatively poor, in the open air, coastal or flush wait in the adverse circumstances corrosion easily and degenerate.
In order to solve in the worldwide durability and the degenerate problem of building, bridge construction, (fibre-reinforced polymer, FRP) composite material is in the application that obtains in recent years more and more widely for fiber-reinforced polymer.FRP is a kind ofly mixed with resin matrix by high-performance fibers such as carbon fiber, glass fiber and basalt fibres, the novel metalloid material that is composited through certain processing technique.FRP has very strong corrosion resistance, also has advantages such as lightweight, high-strength, convenient formation simultaneously.
Summary of the invention
The utility model has overcome shortcoming of the prior art, and a kind of FRP pipe outsourcing FRP muscle material sea sand fibrous concrete flexural member is provided, and has solved the shear behavior difference and the low problem of ductility of traditional F RP muscle material concrete flexural member effectively.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
A kind of FRP pipe outsourcing FRP muscle material sea sand fibrous concrete flexural member comprises the FRP overclad tubes, and is arranged at FRP muscle material and concrete structure in the FRP overclad tubes.
Further, FRP muscle material is the dispersity distributed and arranged along the length direction of FRP overclad tubes.
Further, FRP muscle material is the dispersity distributed and arranged along the cross section radial direction of FRP overclad tubes.
Further, FRP muscle material is arranged at the eccentric position of the tension side of FRP overclad tubes.
Further, the cross section of flexural member is circular or square.
Further, the FRP overclad tubes is Wrapping formed FRP overclad tubes.
Further, concrete structure is the sea sand concrete structure.
Further, the sea sand concrete structure is a sea sand fibrous concrete structure.
Compared with prior art, the beneficial effect of the utility model is:
A kind of FRP pipe outsourcing FRP muscle material sea sand fibrous concrete flexural member comprises the FRP overclad tubes, and is arranged at FRP muscle material and concrete structure in the FRP overclad tubes.
The utility model has adopted concrete and FRP overclad tubes in to traditional flexural member, its good corrosion resistance has solved traditional F RP muscle material concrete flexural member shear behavior difference and the low problem of ductility effectively.
