Description
Technical field
The utility model belongs to building engineering structure field, refers in particular to a kind of FRP tube nucleus heart reinforcing bar sea sand concrete columns.
Background technology
As the continuous development of China's science and technology and the breakthrough successively of building engineering field, New Building Materials are more
Enter among the life of people.Although the large population base in China, the occupancy volume per person of natural resources is seldom, coagulation
Part of the soil as structure, the construction to engineering plays indispensable effect, and river sand is as the bone for preparing concrete
Expect one of composition, it is mainly derived from the excavation of the riverbed on land and massif.In recent years, river sand is largely exploited, to riverbed
And its ecological environment on periphery causes serious destruction.The resource of river sand increasingly deficient, we need badly to find it is a kind of green
The alternative materials of color improve the natural environment that we depend on for existence.And sea sand has that reserves are big, clay content is low, modulus of fineness is equal
It is uniform to be distributed the advantages that wide, but also because of the objectionable impurities that its own contains the corrodible reinforcing bar passivation film such as chlorion, serious shadow
The service life of structure is rung.Therefore, the use of sea sand often needs fresh water to carry out desalt processing, treats that it reaches the mark of building sand
Standard, it can use.But the processing method that tradition desalts to sea sand desalting is extremely cumbersome, and the time length of desalt processing, efficiency is low,
Substantial amounts of freshwater resources and manpower and financial resources are wasted, this causes it lacks in fresh water greatly to hinder caused by the popularization in area
Hinder.
FRP (Fiber Reinforced Polymer, i.e. fiber-reinforced polymer) pipe concretes are because with three-dimensional constraint
Concrete strength, deformable amount are larger and the advantages that designability is good, its industrial factory building that can be used in corrosive environment, near
Tide wet marine environment building, science of bridge building and offshore platform engineering etc..But traditional FRP pipes confined concrete still suffer from
Lower shortcoming, and have a strong impact on its popularization in engineering.First, the fragility of FRP materials is larger so that FRP pipe concretes up to
It can suddenly be destroyed under to ultimate bearing capacity state, and cause the direct avalanche of building structure.In addition, poured in FRP pipe concretes
At initial stage, its rigidity and bearing capacity are relatively low, there may be excessive deformation or the situation of unstability under concrete gravity, and cause to build
Building structure does not reach preferable intensity and load-carrying properties.

Implement the utility model, have the advantages that：
1st, the utility model uses double FRR tubular constructions, and by filling marine sand concrete, structure between ectonexine FRP pipes
FRP pipe concretes cylinder structure in pairs.Because FRP pipes have corrosion resistance, under the isolation work of internal layer FRP pipes, both played pair
The effect that steel skeleton in normal concrete is protected, and improve the entirety of cylinder under the booster action of marine sand concrete
Intensity and load-carrying properties so that the harmful substance such as chlorion in marine sand concrete can not be diffused into the coagulation in internal layer FRP pipes
It is effective to prevent its corrosion to steel skeleton at steel skeleton in soil.I.e. original sea sand can be used directly in this structure, without to original
Beginning sea sand carries out desalt processing, then can be used for marine sand concrete is made and carries out cylinder and pours, drastically increase cylinder
Durability, the process of freshwater resources, omission and desalination is saved, drastically increased the utilization rate of sea sand.
2nd, the utility model is in steel skeleton, steel skeleton built in internal layer FRP pipes by that can delay or suppress concrete oblique segmentation,
Improve rigidity, compression strength, ductility and the anti-seismic performance of cylinder.When coupled column reaches capacity bearing capacity, outer layer FRP pipe and
After the internal fiber of internal layer FRP pipes is oppressed and is broken, steel skeleton can still carry pressure, redistribute stress, and then make whole
Individual cylinder enters softening stress-displacement stage, prevents the generation of brittle break and causes the direct avalanche of building structure.
3rd, the utility model strengthens shape column structure by the connection of connecting plate, steel skeleton and concrete to be formed, significantly
The bending-resistant performance of cylinder is improved, avoids cylinder that the situation of unstability occurs in the construction stage, solves existing FRP pipe concretes
Initial stage is being poured, its rigidity and bearing capacity are relatively low, and there may be excessive deformation or the situation of unstability under concrete gravity.
