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 sum up discovery by engineering practice in recent years, do not have some defectives that can not be ignored that the interchangeable anchoring system of bonding also exists, 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.
In addition, in the utility application " " pyridine of suspension bridge anchor " CN2527588Y " of applicant original application, a kind of structure that connects main rope and pre-stress system with branch sleeve, bearing pin is disclosed, but the anchoring strand by the strand tapered anchorage of field fabrication is partly still adopted in the prestressed concrete anchoring of this structure, thereby, still there is above-mentioned weak point; And this technical scheme is not considered the line style adjustment needs of main rope, can't adjust the main push-towing rope line style in the practice of construction.
Summary of the invention
The purpose of this utility model is to provide a kind of cable-styled anchorage anchoring system of finished product that is applicable to the suspension bridge anchorage, 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 cable-styled anchorage anchoring system of a kind of finished product, comprise that the prestressed concrete anchoring partly is connected with strand 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, shock reducing structure and nut assembly in the concrete, and described anchoring strand is a manufactured finished product anchor cable in factory;
Described fastener inserts comprises and is embedded in pre-pipe laying, the anchor plate in the pre-buried duct and is positioned at spiral bar under the anchor plate; No anti-corrosion material in the pre-pipe laying of fastener inserts;
Described nut assembly comprises spheric washer, Ball faced nut and the locking nut of installing successively;
Described strand connects and partly comprises bearing pin, connector, main cable strand links to each other with the upper end of finished product anchor cable by bearing pin, connector, after the pre-pipe laying of fastener inserts is passed in the lower end of finished product anchor cable, lower end directly is anchored on the anchor plate of back anchor face with nut assembly, and the described shock reducing structure of being made by damping material is installed in the mouth of pipe that the finished product anchor cable enters pre-pipe laying.
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 cable-styled anchorage anchoring system of the finished product 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 in the pre-pipe laying of fastener inserts in the perfusion 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 cable-styled anchorage anchoring system of the finished product of the utility model.
