Abstract
A whole replaceable anchorage system comprises a prepressing force concrete anchoring part and a strand connecting part. The strand connecting part is composed of a draw bar assembly and a connector. A main cable strand to be anchored and the prepressing force concrete anchoring part are connected into one piece through the strand connecting part. The prepressing force concrete anchoring part comprises an anchor stand, a nut assembly and an embedded assembly which is pre-embedded inside the concrete. The anchor strand is a finished anchor cable which is well processed in a factory. The inside of an embedded pipe of the embedded assembly is free of anticorrosive materials. The finished anchor cable of the anchor strand is a hot cast anchor type anchor cable, a cold cast anchor type anchor cable or a full-bundle-extruding anchor type anchor cable. Through long prepared holes are arranged on two sides of prepressing force hole channels of the embedded assembly. When the cable needs to be replaced, a tool cable is installed inside the prepared hole channels on the two sides of the prepressing force hole channels. The force of the finished anchor cable is transferred to the tool cable to bear, and then the whole finished anchor cable is replaced. The whole replaceable anchorage system is reliable in anchoring performance, the construction precision has low requirements, and the cable replacing and construction are convenient.
Description
Technical field
The utility model relates to a kind of prestressing force anchorage anchoring system, especially for the prestressing force anchorage anchoring system of suspension bridge anchorage.
Background technology
The anchorage anchoring system is the lifeline engineering of suspension bridge, and its design, construction quality have determined the safety of bridge and durable to a great extent, and large-scale suspension bridge anchorage anchoring system is divided into two types of shaped steel anchoring system and prestress anchorage systems; Large-scale suspension bridge anchorage anchor system adopts prestress anchorage system more, existing prestress anchorage system has two kinds of patterns, a kind of is the bonded anchoring system of grout injection in prestressed pore passage, a kind of is the nothing interchangeable anchoring system that bonds of the anticorrosion grease of perfusion in prestressed pore passage, the latter compares with the former, and its anti-corrosive properties and durability are comparatively reliable.And because of the latter's prestress wire or grease all can monitor, replaceable, so have " forever " antiseptic property; Just because of this, not having the interchangeable anchoring system of bonding had obtained using more widely in recent years; But the engineering practice by is in recent years summed up and is found, existing nothing some defectives that can not be ignored that interchangeable anchoring system (referring to Fig. 1) also exists that bond, and its major defect shows as:
1, the strand tapered anchorage reliability requirement is higher:
Traditional prestressing with bond steel bundle is at just pressure injection cement paste in prestressed pore passage soon after the stretch-draw, prestressing force is reliable in time short before grouting so need only, and grouting quality guarantees, so just in case its component failure of ground tackle assembly, cement paste itself still can provide enough bond stresss to prestressed strand, the prestressing force of setting up in structure can be not entirely ineffective owing to the inefficacy of ground tackle, and the anchorage anchoring system prestressed strand of perfusion grease is very big to the dependence of ground tackle, in case the ground tackle assembly goes wrong, its prestressing force is with entirely ineffective.
2, construction process requirement height:
The grease that present interchangeable anchorage anchoring system pours in prestressed pore passage is a liquid state, and purpose is that convenient perfusion is changed with later grease; But thus, the sealing of system has proposed very high request to construction, constructing operation is arranged slightly or check not in place, seepage will take place in the grease in the system, this not only influences outward appearance, and the seepage that the more important thing is is difficult to radical cure to be handled, and has strengthened the operation maintenance cost; Early stage application of having built the suspension bridge of interchangeable anchorage anchoring system, because of inadequately, in design, all there is in various degree grease seepage in the not careful anchoring system that causes on the construction technology to its sealing understanding.
3, prestressing force replacing technology is loaded down with trivial details:
When need are changed prestressing force, to emit the grease in the prestressed pore passage earlier, the single then prestressing force that loosens, single replacing steel strand, single tendon stretch anchoring prestressing force also needs the supplementary irrigation grease at last, and whole replacing process is comparatively cumbersome.
Summary of the invention
The purpose of this utility model is to provide a kind of integral body interchangeable anchorage anchoring system, and this system anchoring property is reliable, the construction precision requirement is low, and changes the rope easy construction.
The technical scheme that addresses the above problem is: the interchangeable anchorage anchoring system of a kind of integral body, comprise that the prestressed concrete anchoring partly is connected with the strand of being made up of rod assembly and connector partly, connecting main cable strand and the prestressed concrete anchoring that partly will intend anchoring by strand partly fuses, described prestressed concrete anchoring partly comprises the anchoring strand, is embedded in fastener inserts and nut assembly in the concrete, and described anchoring strand is a manufactured finished product anchor cable in factory; No anti-corrosion material in the pre-pipe laying of fastener inserts.
Its further technical scheme is: the anchor head at described finished product anchor cable two ends as the anchoring strand is hot-cast anchor formula, chill casting anchor formula or whole bundle extruding anchor formula.
The prestressed pore passage both sides of described fastener inserts are provided with elongated preformed hole.
The whole interchangeable anchorage anchoring system of the utility model is compared with the interchangeable anchorage anchoring system of existing nothing bonding, has following beneficial effect:
1, the anchoring property of finished product anchor cable is better than existing do not have the interchangeable anchorage anchoring system of bonding and constructing at the scene by the anchor cable of intermediate plate anchor anchoring.
2, the finished product anchor cable is low to construction requirement, need not to pour in prestressed pore passage anti-corrosion material, easy construction.
3, in the time of need changing prestressed concrete anchoring finished product anchor cable partly, only need finished product anchor cable integral body is changed, change easy construction.
Be described further below in conjunction with the technical characterictic of drawings and Examples the whole interchangeable anchorage anchoring system of the utility model.
