Abstract
The invention discloses a kind of High-strength concrete member with local built-in fibre cloth restriction, this component is formed by indulging muscle (1), stirrup (2), high-strength concrete, cloth (3) and iron sheet (4).Vertical muscle (1) and stirrup (2) colligation form reinforcing cage.At vertical muscle (1) outside wrapping iron sheet (4), iron sheet (4) is interval wrapping between adjacent stirrup (2).Iron sheet (4) width and stirrup (2) spacing just as, iron sheet (4) junction adopts welding.Iron sheet (4) is had to wrap up between component ends two stirrup (2).Cloth (3) sticks with glue in iron sheet (4) outside, often opens iron sheet (4) and pastes 5-8 layer cloth (3).Cloth (3) retrains from inside component, improves compressive strength and the supporting capacity of component, improves ductility.Because there is high-strength concrete topping cloth (3) outside, be conducive to the long-term binding effect ensureing cloth (3).In addition, cloth (3) is pasted onto on iron sheet (4), and the stress avoiding cloth (3) is concentrated, and improves the utilization rate of cloth (3).
Description
Technical field
The application relates to a kind of restraint and high-strength concrete component.
Background technology
In the last few years, be used widely in the construction work that high-strength concrete was a large amount of at home and abroad and bridge engineering.Although high-strength concrete has higher intensity and durability than ordinary concrete, and sectional dimension of members can be reduced, alleviate dead load and reduce earthquake response, high-strength concrete has obvious fragility.Therefore to carry out retraining the ductility improving its component, to use high-strength concrete component in a large number in earthquake zone to high-strength concrete.At present, cloth is widely used in reinforcing in existing concrete structural system, utilizes carbon cloth or carbon fiber strips strengthen common concrete column and reinforce, and forms carbon-fiber textile concrete combined structure system, improve concrete tension, pressure bearing capacity, improve its ductility.But cloth is outside exposed, effectively do not protect, its long-term binding effect can be affected.In addition, the refractoriness of the epoxy resin usually adopted when pasting cloth and all non-constant of heat-resisting quantity, the mechanical property of general epoxy resin 100 degrees Celsius time will be subject to very large impact.Moreover, because lateral strain during concrete compression is uneven, easily cause cloth stress to concentrate, reduce the utilization rate of cloth.
Summary of the invention
The object of the present invention is to provide a kind of more simple effectively, cost is low and be conducive to the High-strength concrete member with local built-in fibre cloth restriction of long-term constraint, outside reinforcing cage, namely arranges iron sheet and cloth to improve the performance of component.
Technical scheme of the present invention is as follows:
A kind of High-strength concrete member with local built-in fibre cloth restriction, is made up of vertical muscle (1), stirrup (2), high-strength concrete, cloth (3) and iron sheet (4).Vertical muscle (1) and stirrup (2) colligation form reinforcing cage.At vertical muscle (1) outside wrapping iron sheet (4), iron sheet (4) is interval wrapping between adjacent stirrup (2), and the both sides up and down of a stirrup (2), only have side to have iron sheet (4) to wrap up.Cloth (3) sticks with glue in iron sheet (4) outside.Iron sheet (4) width is identical with stirrup (2) spacing, and stirrup (2) spacing is between 100mm-300mm.Iron sheet (4) junction adopts welding.Iron sheet (4) is had to wrap up between component ends two stirrup (2), if component has odd number stirrup (2), then in component end, iron sheet (4) not interval wrapping, but wrap up two iron sheets (4) continuously.Cloth (3) width is identical with iron sheet (4) width, pastes iron sheet (4) outside.Each iron sheet (4) external pasting 5-8 layer cloth (3), sticks with glue between every layer of cloth (3).Because iron sheet (4) is between adjacent stirrup (2), stirrup (2) can limit the position of iron sheet (4), therefore during disturbing concrete, can not cause the displacement of iron sheet (4), thus can not cause distortion and the displacement of cloth (3).Water after smashing high-strength concrete, there is high-strength concrete topping cloth (3) outside.
The present invention compared with prior art; cloth retrains from inside concrete; improve compressive strength and the supporting capacity of component; improve ductility; and outside cloth, have high-strength concrete topping, effectively can protect cloth, concrete is poor conductor of heat simultaneously; cloth alite paste can be avoided directly by high temperature action, be conducive to the long-term binding effect ensureing cloth.In addition, cloth is pasted onto on iron sheet, avoids because concrete lateral strain is uneven that cloth stress that is that cause is concentrated, and improves the utilization rate of cloth.

Detailed description of the invention
Below in conjunction with embodiment, the present invention will be further described:
Embodiment 1
First vertical muscle (1) is become reinforcing cage with stirrup (2) colligation, then at vertical muscle (1) outside wrapping iron sheet (4).Stirrup (2) radical is even number, and iron sheet (4) is interval wrapping between adjacent stirrup.Iron sheet (4) width is identical with stirrup (2) spacing.Iron sheet (4) interface adopts welding.Often opening iron sheet (4) first gluing outward, then paste cloth (3).Cloth (3) width is identical with iron sheet (4) width.Often open iron sheet (4) external pasting 5 layers of cloth (3), stick with glue between every layer of cloth (3).After formwork, water and smash high-strength concrete, constitute a kind of High-strength concrete member with local built-in fibre cloth restriction.
Embodiment 2
First vertical muscle (1) is become reinforcing cage with stirrup (2) colligation, then at vertical muscle (1) outside wrapping iron sheet (4).Stirrup (2) radical is odd number, and iron sheet (4) is interval wrapping between adjacent stirrup, and between last three stirrups (2) of a component end, iron sheet (4) is wrapped up continuously, and guaranteeing has iron sheet (4) to wrap up between component ends two stirrup (2).Iron sheet (4) width is identical with stirrup (2) spacing.Iron sheet (4) interface adopts welding.Often opening iron sheet (4) first gluing outward, then paste cloth (3).Cloth (3) width is identical with iron sheet (4) width.Often open iron sheet (4) external pasting 8 layers of cloth (3), stick with glue between every layer of cloth (3).After formwork, water and smash high-strength concrete, constitute a kind of High-strength concrete member with local built-in fibre cloth restriction.
