Abstract
The invention discloses a cement-based composite and steel pipe combined compound column. A concrete inner core is located in a pipe fitting which is peripherally covered with a cement-based composite layer, and the cement-based composite layer comprises cement, sand and/or mineral admixtures, water, steel fibers and PVA (polyvinyl acetate) fibers. The invention further provides a manufacturing method of the cement-based composite and steel pipe combined compound column. The method includes: A, setting up a cement-based composite layer outer-layer formwork or mould on the periphery of the pipe fitting; B, depositing concrete inside the pipe fitting, injecting the cement-based composite into an inner cavity between the pipe fitting and the outer-layer formwork or mould to form the cement-based composite layer; C, after the cement-based composite layer is solidified and dried, demolishing the outer-layer formwork or mould. The cement-based composite on the outer layer of the cement-based composite and steel pipe combined compound column can replace traditional reinforcement, and the pipe fitting serves as a skeleton of the reinforced compound column, so that overall bending strength and tensile strength of the compound column can be enhanced, and ultimate tensile strain can be up to 0.7% maximally.
Description
Technical field
The present invention relates to a kind of cement-base composite material and steel pipe combination combined column.Present invention also offers the method manufacturing above-mentioned cement-base composite material with steel pipe combination combined column.
Background technology
Tradition cylinder is generally adopted reinforced concrete structure, it is necessary to expend plenty of time assembling reinforcement cage, and it is general to pour into a mould the cylinder bending resistance that obtains, resistance to compression, comparison of seismic resistant properties.Under being subject to violent earthquake and Impact Load, due to Lack of support, deformation power consumption poor, cause building collapsing.The invention provides a kind of method strengthening structural bearing capacity and anti-seismic performance.
Summary of the invention
In view of the deficiency that background technology exists, the technical problem to be solved is to provide the cement-base composite material and steel pipe combination combined column that a kind of bending resistance, bending resistance and anti-seismic performance are better and manufacturing schedule is shorter.Present invention also offers the method manufacturing above-mentioned cement-base composite material with steel pipe combination combined column.
The present invention has adopted the following technical scheme that: cement-base composite material and steel pipe combination combined column, including pipe fitting, pipe fitting periphery is enclosed with cement-base composite material layer, and cement-base composite material layer comprises cement, sand and/or mineral and closes material, water, steel fibre and PVA fiber.
The method of cement-base composite material and steel pipe combination combined column is stated in manufacture provided by the invention, comprises the following steps: A, set up cement-base composite material layer outer template or mould in pipe fitting periphery；B, in the inner chamber between pipe fitting and outer template or mould inject cement-base composite material formed cement-base composite material layer；C, after the solidification of cement-base composite material layer mummification, remove outer template or mould.
Cement-base composite material provided by the invention and steel pipe combination combined column and manufacture method thereof have the advantage that 1, can substitute tradition reinforcing bar, and the overall bending resistance of combined column, shearing resistance, tension and anti-seismic performance can be made to be strengthened, ultimate tensile strength is maximum can to 0.7%；2, save the work of assembling reinforcement, can save labour turnover and the reduction of erection time；3, after cement-base composite material parcel also confined concrete inner core, after adding steel fibre and PVA fiber due to the cement-base composite material of outer layer, tensile property strengthens and has certain ductility, make damaged surface that crack not easily to occur, improve durability and the service life of structure.4, pipe fitting can have concrete inner core mould and the effect of two kinds of skeleton concurrently, enables concrete inner core and cement-base composite material layer to pour into a mould simultaneously, and intensity aspect has again further lifting.
