Description
Technical field
The utility model relates to a kind of ground tackle of strand tapered anchorage of civil engineering carbon fibre reinforced composite plate, particularly a kind of strand tapered anchorage of carbon fibre reinforced composite plate.
Background technology
Carbon fibre reinforced composite (be called for short CFRP) is by fibrous material and the matrix material high performance material by certain process combining, because it has the advantages such as lightweight, high-strength, corrosion-resistant, anti-fatigue performance is good, become a kind of new structural material of field of civil engineering gradually.According to different product forms, CFRP can be divided into: CFRP sheet material, CFRP bar and CFRP tubing.Sheet material is convenient to transport relative to bar and tubing, applies more extensive in structural strengthening transformation, but most case history, be all that low-level uses.In Practical Project, carbon fiber carries out common stickup at body structure surface in sheet form, and rate of utilization of strength does not reach 20% of normal intensity usually, and the stress level under serviceability limit state does not generally reach 5% of normal intensity.A large amount of theory analysises and experimental study show, significantly can improve stock utilization, significantly improving the service behaviour of structure to pasting after carbon fibre material Shi Hanzhang.
Carbon fiber board is needed to the ground tackle of function admirable to its Shi Hanzhang by stretch-draw, ground tackle mainly comprises binding ground tackle and the large class of strand tapered anchorage two.Bond type anchorage anchoring efficiency is high, reliable and stable, does not damage carbon fiber.But due to the physical characteristic that carbon fiber board itself has, size macrostructure that is high to the requirement of binding material, ground tackle is complicated, cause work progress inconvenient, simultaneously ground tackle can not reuse, binding material hardening time long and durability need checking further etc.
Strand tapered anchorage flexible design, can stretch-draw immediately after assembling; Centering is convenient; Interchangeability is good, but traditional strand tapered anchorage intermediate plate end stress is concentrated, and easily damages fiber.
Therefore, needing one to have can apply even reliable retention power to CFRP plate, and make full use of the advantage that carbon fiber board itself has, structure is simple, light, can reuse and the high ground tackle of operating efficiency.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of strand tapered anchorage of carbon fibre reinforced composite plate, this ground tackle overcomes the deficiency of the strand tapered anchorage ground tackle that there is carbon fibre reinforced composite plate, even reliable retention power can be applied to the strand tapered anchorage of carbon fibre reinforced composite plate, can reuse, anchoring efficiency is high, be convenient to engineer applied.
For solving the problems of the technologies described above, the present invention includes carbon fibre reinforced composite (being called for short CFRP) plate (band), first layer of polyurethane, second layer of polyurethane, intermediate plate and endoporus are the anchor ring of cone, two formed objects cell cubes that described intermediate plate cuts open by cone are formed, described cell cube is first module body and second unit body, described first module body becomes the conical surface with the external surface of second unit body, and match with the conical surface of anchor ring endoporus, the inner surface of described first module body is inlaid with the first layer of polyurethane, the inner surface of described second unit body is inlaid with the second layer of polyurethane, carbon fibre reinforced composite plate is provided with between described first layer of polyurethane and the second layer of polyurethane, described anchor ring is placed on carbon fibre reinforced composite plate and the first layer of polyurethane, second layer of polyurethane, on the assembly of first module body and second unit body.
Further, described anchor ring is steel anchor ring, and described intermediate plate is variable steel-degree intermediate plate.
Further, described first layer of polyurethane and the second layer of polyurethane shape are wedge shape.
Advantage of the present utility model and effect as follows:
(1) be embedded on steel clamp sheet by polyurethane, intermediate plate rigidity can be made to change, during carbon fibre reinforced composite plate tension, chucking power is relatively more even, not easy damaged fiber;
(2) friction factor between polyurethane and carbon fibre reinforced composite plate is larger than the friction factor between steel and carbon fibre reinforced composite plate, can improve anchoring efficiency.
(3) because anchor ring is fixed, structure is simple, light, can reuse.
