Description
Technical field
The present invention relates to building element technical field, in particular to a kind of basalt fibre of confined concrete models is compound
Pipe.
Background technique
Pillar or beam inside building structure, generally use steel core concrete column, internal using steel pipe as constraint material
Fill concrete, but the fire resistance property of steel and resistance to corrosion are excessively poor, therefore annual maintenance cost is relatively high, without
It helps, is dangerous.In addition conventional steel is whole, is disconnected and can guarantee that it does not directly take on external loads, to reach to mixed
The purpose of solidifying soil constrained maximization, can also substantially reduce the possibility that local buckling occurs for steel pipe itself, but steel pipe interval is cracked and needed
Concreting is used, position of cracking in the process is commonly present spillage problem.Basalt fibre is usually to be added as a kind of spike
Into concrete, for improving intensity, but basalt fibre production is become into composite material and is used as civil engineering practical application
In, instead of traditional concrete filled steel tubular member peripheral steel pipe this there has been no forefathers' researchs.
207598429 U of China Patent Publication No. CN, CN 207673491U, respectively at 10 and 2018 years 07 month 2018
" a kind of basalt fibre steel reinforced concrete composite pillar for marine environment " is disclosed within 31 days 07 month, by basalt fibre
Adding type steel inside pipe, will lead to waste of material, uneconomical, and not meet the requirement of green building.Because of basalt fibre profile
As the constraint of periphery, performance is better than steel pipe, and inside casting concrete is primarily subjected to the effect of pressure, the Basalt Type of outside
The constraint that material provides can make the intensity increase of this composite component very high.And the patent does not consider the leakage of pipe inner concrete
Slurry problem, especially in the seawater, seawater have corrosivity to the concrete in pipe, then can also play corruption to the fashioned iron in pipe
Erosion effect, therefore the durability of multiple tube can be greatly shortened, to bring very big security risk to ocean structure, while this is specially
Benefit does not account for the slippage between pipe inner concrete and basalt fibre pipe, therefore basalt fibre multiple tube and core yet
Heart concrete does not give full play to the material property of the two, thus intensity and not up to optimum state.
Summary of the invention
It is an object of the invention to overcome disadvantages mentioned above and provide it is a kind of can prevent concrete spillage, can solve in pipe mix
Slippage between solidifying soil and basalt fibre pipe, and it is mixed with the high constraint of good corrosion resistance, ductility, bearing capacity
Solidifying earth pillar basalt fibre multiple tube.
