By bridge pier is applied to ring orientation prestress at a certain distance, be a kind of effective ways that improve load carrying capacity of bridge, improve its functional performance.High strength fibre cloth is a kind of more high-tensile fibrous material that has, and wherein, the tensile strength of basalt fiber cloth can reach 3000-4840Mpa, and modulus of elasticity is 80-100Gpa, and intensity, the modulus of elasticity of carbon cloth are higher.Cloth is enclosed and is enclosed within on bridge pier, bridge pier is applied to ring orientation prestress, bridge pier is carried out to active to be reinforced, can change bridge pier inside concrete stress state, can fundamentally solve the generation again of bridge pier disease, be also bridge construction while passing through interim heavy equipment, equipment, guarantee the stressed safe effective way of bridge pier.
Application number is: 201120008128.4 utility model patent discloses a kind of by anchor head, screw rod, nut be wrapped in the high-strength fiber material self-locking anchor device that the high strength fibre cloth that is reinforced component surface forms, this anchor device simple structure, easy to operate, can carry out reinforcement and strengthening to existing structure quickly and easily, improved the supporting capacity of existing structure and extended application life.But the syndeton that is limited to anchor head and high strength fibre cloth end in this patent, its performance in following several respects remains further to be improved:
1, the anchoring ability of cloth end remains further to be improved;
2, can not adopt existing tensioning equipment to implement stretch-draw, the stretching force be applied on cloth is on the low side; Can not guarantee the consolidation effect to ruggedized construction;
3, in loading and holding the lotus process, there is the slippage risk in anchor head place cloth, and this bridge construction that reinforcing is born to fatigue loading is very disadvantageous.
Summary of the invention
The utility model provides a kind of anchoring ability that improves the cloth end for solving the technical problem existed in known technology, avoid loading with hold the lotus process in the end of cloth the stretching force of slippage, increased fiber cloth appears, thereby guarantee the high tensile strength fibrous material wedge shape anchor device to the consolidation effect of ruggedized construction.
The technical scheme that the utility model is taked for the technical problem existed in the solution known technology is:
A kind of high tensile strength fibrous material wedge shape anchor device, comprise the high strength fibre cloth of wrapping treating the ruggedized construction surface; Comprise two anchor heads, two anchor heads are connected with the two ends of high strength fibre cloth respectively, it is characterized in that: be equipped with the wedge shape plug-in opening on each anchor head; Comprise two otic placodes, two otic placodes are separately fixed on the lateral surface of two anchor heads; Comprise the connecting rod of being made by the high-strength deformed steel bar muscle, the two ends of described connecting rod are installed on two otic placodes, and carry out anchor connection by ground tackle; The end construction of described high strength fibre cloth is: comprise fixed core, fixed core consists of the steel plate bar with circular arc corner; The end of high strength fibre cloth scribbles epoxy resin, and is intertwined and connected with fixed core, forms winding head; Comprise the clamping steel plate, clamp steel plate and be clamped in the both sides of winding head, and connect by high-strength bolt; Comprise epoxy resin outer wrapping body, described epoxy resin outer wrapping body is coated on and clamps outside steel plate; Described epoxy resin outer wrapping body forms the wedge shape plug-in mounting with anchor head and coordinates.
The utility model can also adopt following technical scheme:
Described wedge shape plug-in opening is V shaped hole, and described epoxy resin outer wrapping body is the V-type body structure matched.
Advantage and the good effect that the utlity model has are:
The utility model adopts above-mentioned anchor device, than prior art, increase steel plate gripping layer and epoxy resin outer wrapping body layer outside the winding structure of the end of high strength fibre cloth, and epoxy resin outer wrapping body layer and anchor head form the wedge-like engagement structure, it has improved the anchoring ability of cloth end on the one hand, on the other hand, due to the wedge action of anchor head and epoxy resin outer wrapping body, avoid loading with hold the lotus process in the end of cloth slippage appears.In addition, two otic placodes connect by connecting rod, can adopt existing food-through tension jack to carry out stretch-draw to connecting rod, thereby realize the stretch-draw to cloth.The stretching mode of this kind to cloth, can guarantee it is applied to larger stretching force, and then guarantee the consolidation effect to ruggedized construction.
