Abstract
The invention discloses a high-strength concrete member with a local built-in fibre cloth restriction. The high-strength concrete member is composed of a longitudinal bar (1), stirrups (2), a high-strength concrete, fibre cloth (3) and iron sheets (4), wherein the longitudinal bar (1) and the stirrups (2) are bound to form a reinforcement cage. The outside of the longitudinal bar (1) is bound with the iron sheets (4), and the iron sheets (4) are bound between adjacent stirrups (2) at intervals; the width of the iron sheets (4) is the same as a space of the stirrups (2); a connection part of the iron sheets (4) is welded. The iron sheets (4) are bound between two stirrups (2) at an end part of the member; the fibre cloth (3) is glued outside the iron sheets (4); each iron sheet (4) is glued with 5-8 layers of fibre cloth (3). The member is restricted by the fibre cloth (3) from the inside, so that compression strength and a bearing ability of the member are improved, so the ductility is improved. Because the outside of the fibre cloth (3) is bound with a high-strength concrete protecting layer, a long-term restriction effect of the fibre cloth (3) is effectively guaranteed. Moreover, the fibre cloth (3) is glued on the iron sheets (4), so that stress concentration of the fibre cloth (3) is avoided and a utilization rate of the fibre cloth (3) is improved.
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 a large amount of at home and abroad construction work of high-strength concrete and the bridge engineering.Though high-strength concrete has higher intensity and durability than ordinary concrete, and can reduce the member section size, alleviate dead load and reduce earthquake response, high-strength concrete has tangible fragility.Therefore to retrain the ductility that improves its member to high-strength concrete, so that use the high-strength concrete member in a large number in the earthquake zone.At present; Cloth is widely used in reinforcing in the existing concrete structural system, utilizes carbon cloth or carbon fiber band that the ordinary concrete post is strengthened and reinforces, and forms carbon cloth concrete combined structure system; Improve concrete tension, press bearing capacity, improve its ductility.But cloth is exposed outside, does not effectively protect, and can influence its long-term binding effect.In addition, the refractoriness and all non-constant of heat-resisting quantity of the epoxy resin that adopts usually when pasting cloth, the mechanical property of general epoxy resin in the time of 100 degrees centigrade will receive very large influence.Moreover, lateral strain is inhomogeneous during owing to concrete compression, causes cloth stress to concentrate easily, reduces the utilization rate of cloth.
Summary of the invention
The object of the present invention is to provide a kind of simple more effectively, cost is low and help the local built-in fabric cloth restraint and high-strength concrete component of long-term constraint, and the performance that iron sheet and cloth improve member promptly is set outside reinforcing cage.
Technical scheme of the present invention is following:
A kind of local built-in fabric cloth restraint and high-strength concrete component 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 the outside wrapping of vertical muscle (1) iron sheet (4), iron sheet (4) is wrapping at interval between adjacent stirrup (2), and the both sides up and down of a stirrup (2) only have a side that iron sheet (4) wrapping is arranged.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.Welding is adopted in iron sheet (4) junction.Iron sheet (4) wrapping is arranged between component ends two stirrups (2), if member has odd number stirrup (2), then in end of member, iron sheet (4) is wrapping at interval not, but wraps 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 the adjacent stirrup (2), stirrup (2) can limit the position of iron sheet (4), so during disturbing concrete, can not cause the displacement of iron sheet (4), thereby can not cause the distortion and the displacement of cloth (3).Water smash high-strength concrete after, there is the high-strength concrete topping cloth (3) outside.
The present invention compared with prior art, cloth retrains concrete internally, has improved the compressive strength and the supporting capacity of member; Improved ductility; And there is the high-strength concrete topping cloth outside, can effectively protect cloth, and concrete is a poor conductor of heat simultaneously; Can avoid the cloth alite paste directly to receive high temperature action, help guaranteeing the long-term binding effect of cloth.In addition, cloth sticks on the iron sheet, and the cloth stress of having avoided causing owing to the concrete lateral strain is inhomogeneous is concentrated, and has improved the utilization rate of cloth.

The specific embodiment
Below in conjunction with embodiment the present invention is further specified:
At first colligation becomes reinforcing cage with stirrup (2) vertical muscle (1), then at vertical muscle (1) outside wrapping iron sheet (4).Stirrup (2) radical is an even number, and iron sheet (4) is wrapping at interval between adjacent stirrup.Iron sheet (4) width is identical with stirrup (2) spacing.Iron sheet (4) interface adopts welding.First gluing outside every iron sheet (4) is pasted cloth (3) then.Cloth (3) width is identical with iron sheet (4) width.Every iron sheet (4) 5 layers of cloth of external pasting (3) stick with glue between every layer of cloth (3).After the formwork, water and smash high-strength concrete, constituted a kind of local built-in fabric cloth restraint and high-strength concrete component.
At first colligation becomes reinforcing cage with stirrup (2) vertical muscle (1), then at vertical muscle (1) outside wrapping iron sheet (4).Stirrup (2) radical is an odd number, and iron sheet (4) is wrapping at interval between adjacent stirrup, and between last three stirrups (2) of an end of member, iron sheet (4) is wrapping continuously, guarantees to have between component ends two stirrups (2) iron sheet (4) wrapping.Iron sheet (4) width is identical with stirrup (2) spacing.Iron sheet (4) interface adopts welding.First gluing outside every iron sheet (4) is pasted cloth (3) then.Cloth (3) width is identical with iron sheet (4) width.Every iron sheet (4) 8 layers of cloth of external pasting (3) stick with glue between every layer of cloth (3).After the formwork, water and smash high-strength concrete, constituted a kind of local built-in fabric cloth restraint and high-strength concrete component.
