Description
One, technical field:
The utility model relates to a kind of anchor, particularly a kind of prestressed tendon intermediate plate anchor.
Two, background technique:
Existing prestressed tendon intermediate plate anchor is as shown in Figure 3: this anchor is made up of common prestress wire 8, anchor plate 9, anchor ring 11 and intermediate plate 10; Intermediate plate 10 clamping steel strand, male cone (strobilus masculinus) by intermediate plate matches with the internal taper hole of anchor ring, and is stressed when taper hole small end direction is moved when steel strand, drives the intermediate plate follow-up, thereby make intermediate plate produce a very big chucking power to steel strand, steel strand anchor in the anchor ring taper hole is tight.The deficiency that this technology exists is:
One: steel strand hardness is higher, and the intermediate plate thread form is thinner, and the intermediate plate tooth directly contacts with steel strand, when stressed, may pull the intermediate plate thread form, causes the stripped thread phenomenon;
Its two: the steel strand antiseptic property is relatively poor, especially in interlock place of intermediate plate and steel strand, easily produces corrosion, influences the life-span of steel strand;
Its three: the weight of steel strand is bigger, on a large amount of engineerings such as bridge of using drag-lines, will increase the weight of drag-line and the deadweight of bridge greatly, makes troubles for design and construction;
Its four: whole anchor size is relatively large, and for ground tackle is installed outside member, exposed parts is also bigger, thereby causes the overall dimensions of member bigger, and engineering cost improves; Ground tackle is installed in member, can be to a certain degree weakened the intensity of node, particularly reduce shock strength.
Three, summary of the invention:
The technical problems to be solved in the utility model is: the intermediate plate tooth directly contacts with steel strand in the pre existing stress rib intermediate plate anchor, may pull the intermediate plate thread form when stressed, causes the stripped thread phenomenon; In interlock place of intermediate plate and steel strand, easily produce corrosion, influence the life-span of steel strand; The volume of steel strand is big, weight is heavier, and the problem of construction inconvenience and the more high aspect of engineering cost provides a kind of antiseptic property of product, stressing conditions to improve, the security and stability of life of product, engineering improves, the weight of product is lighter, and cost is low, the intermediate plate anchor of easy construction.
The technological scheme of dealing with problems is: 1. use prestressing force non-metallic fiber muscle---be called pre-stress FRP muscle, particularly carbon fibre bar or rope again and replace common prestress wire; 2. carbon fibre bar or rope peripheral hardware steel sheath, and fill with special binding resin in the sheath internal pressure; 3. intermediate plate directly is clamped on the outer surface of the oversheath with certain rigidity and suppleness, the extruding of the high-strength cohesive force by binding resin and a small amount of distortion of oversheath and special binding resin produces chucking power to carbon fibre bar or rope.
Its concrete structure is: a kind of pre-stress FRP muscle intermediate plate anchoring body device with sheath, comprise prestressed tendon, anchor plate, intermediate plate and anchor ring, it is characterized in that: described prestressed tendon is with oversheath outward, intermediate plate directly is clamped on the outer surface of prestressed tendon oversheath, fills binding resin in the sheath internal pressure.
Described prestressed tendon is a prestressing force non-metallic fiber muscle, and this non-metallic fiber muscle comprises carbon fibre bar, aramid fiber reinforced plastic bars, and the glass fibre muscle, the pbo fiber muscle, described oversheath 3 is the steel sleeves with certain rigidity and suppleness.
Described carbon fibre bar can be single non-smooth gluten, as top screw thread is arranged, and the surface is uneven, and also can be around the carbon fiber rope that forms by 7 diameters fine carbon fibre muscle strand that is 1.5～5mm.
The binding resin of sheath internal pressure perfusion is the modified epoxy with toughness reinforcing, fast hard, enhancing, anti-aging function.
During use, when the prestressing force non-metallic fiber muscle that is with steel sheath stressed when taper hole small end direction is moved, the follow-up of drive intermediate plate, clamp the steel oversheath, and push binding resin in right amount, thereby prestressing force non-metallic fiber muscle (carbon fibre bar or carbon fiber rope) is produced a very big chucking power, and anchor is tight in the anchor ring taper hole with prestressing force non-metallic fiber muscle (carbon fibre bar or carbon fiber rope).Its major advantage is as follows:
1. prestressing force non-metallic fiber muscle---be that pre-stress FRP muscle weatherability excellent, antiseptic property are good, be difficult for the generation corrosion, long service life is used for the coastal area engineering or the ocean engineering effect is more outstanding;
2. fill binding resin in the sheath, prestressing force non-metallic fiber muscle does not contact with air, further strengthens antiseptic property;
3. pbo fiber muscle, carbon fibre bar or carbon fiber rope, aramid fiber reinforced plastic bars and so on prestressing force non-metallic fiber muscle Young's modulus height, relatively more responsive to stress deformation, thereby the load that the overwhelming majority is added on the member can both affact on carbon fibre bar or the carbon fiber rope, reduced deformation of members, increase the security and stability of member, improved the bulk life time of member;
4. pbo fiber muscle, carbon fibre bar or carbon fiber rope intensity height, in light weight can reduce the deadweight of member widely; Anti-fatigue performance is good, can improve the security and stability of member;
5. carbon fibre bar, carbon fiber rope, aramid fiber reinforced plastic bars flexural rigidity are low, and better softness is easy to reel, are convenient to the carrying of long rope and set up.
6. the direct clamping reinforcing bar of intermediate plate oversheath outer surface, directly do not contact with carbon fibre bar or carbon fiber rope and so on prestressing force non-metallic fiber muscle, both can avoid pulling the intermediate plate thread form, can avoid scratch carbon fibre bar or carbon fiber rope and so on prestressing force non-metallic fiber muscle again;
7. whole anchor size is less, and the headspace that is used to install ground tackle on the member also can be less, thereby can reduce the size of member to a certain extent, reduces engineering cost, saves cost.
