Abstract
The invention discloses a cement-based composite restraint concrete compound column comprising a concrete inner core. The concrete inner core is peripherally wrapped 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 manufacture method of the cement-based composite restraint concrete compound column. The method includes the following steps: A, making a mould or setting up a formwork for pouring the concrete inner core, and demolishing the mould after the concrete inner core is solidified; B, setting up a cement-based composite layer mould on the periphery of the concrete inner core; C, injecting cement-based composite into an inner cavity between the concrete inner core and the mould; D, 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 restraint concrete compound column can replace traditional reinforcement, 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 limited concrete combined column.Present invention also offers the method manufacturing above-mentioned cement-base composite material limited concrete combined column.
Background technology
Tradition cylinder is generally adopted reinforced concrete structure, fragility is big, ductility is poor, shock resistance is weak, when there is violent earthquake, owing to Lack of support and power consumption are poor, cause that building or works produce collapse, in order to solve the problems referred to above, the present invention proposes a kind of new combinative structure post, and bearing capacity is high, shock resistance strong, develops skill support for engineering structure post.
Summary of the invention
In view of the deficiency that background technology exists, the technical problem to be solved is to provide a kind of bending resistance, resistance to compression, anti-seismic performance is better and manufacturing schedule is shorter cement-base composite material limited concrete combined column.Present invention also offers the method manufacturing above-mentioned cement-base composite material limited concrete combined column.
The present invention has adopted the following technical scheme that: cement-base composite material limited concrete combined column, it is characterized in that: include concrete inner core, concrete inner core 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 the above-mentioned cement-base composite material limited concrete combined column of manufacture provided by the invention: comprise the following steps: A, make mould or set up pouring template concrete inner core, after concrete inner core solidification mummification, removing mould or template;B, set up cement-base composite material layer outer template or mould in concrete inner core periphery;C, in the inner chamber between concrete inner core and outer template or mould inject cement-base composite material formed cement-base composite material layer;D, after the solidification of cement-base composite material layer mummification, remove outer template or mould.
Cement-base composite material limited concrete combined column provided by the invention and manufacture method thereof have the advantage that 1, can substitute tradition reinforcing bar, and the overall bending resistance of combined column, shearing resistance and tensile strength can be made to be strengthened;
2, the Compressive Bearing Capacity of pillar, ductility and energy dissipation capacity are significantly improved;
3, save the work of assembling reinforcement, can save labour turnover and the reduction of erection time;
4, 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 pillar.
