Description
Technical field
The utility model relates to prestressed cable anchoring system manufacturing technology field, the especially a kind of formula that bonds ground tackle that includes the squash type composite entity of steel strand.It is squash type composite entity dragline anchorage.
Background technology
In recent years, along with the development of highway, railway construction, prestressed anchor has also obtained good application; The formula that the bonds ground tackle of prior art is will push casing pressure knot on presstressed reinforcing steel with extruder, and it is pre-buried or be arranged in concrete, steel structure bridge, and arranges on demand and carry out stretch-draw.The formula that the bonds ground tackle of prior art has sub-thread extruding anchor, monolithic extruded anchor; Wherein, the sub-thread extruding anchor is single presstressed reinforcing steel to be installed on once to push in extruded sleeve form the sub-thread extruding anchor, and monolithic extruded anchor is many presstressed reinforcing steels to be installed on once to push in an extruded sleeve form monolithic extruded anchor; Before once pushing, monolithic extruded anchor for the frictional force that increases presstressed reinforcing steel and extruded sleeve, the increase extruded sleeve bond stress to presstressed reinforcing steel, in the presstressed reinforcing steel termination, tapered sleeve is housed, but this tapered sleeve often can come off; Again due to the extruding anchor anchor monolithic extruded after, just at its external surface processing connecting thread, cause monolithic extruded anchor connecting thread difficulty of processing large, the problem such as cost of manufacture is high, anchorage reliability is low.
The utility model content
The purpose of this utility model is to provide a kind of squash type composite entity dragline anchorage, and it is large that the method for this squash type composite entity dragline anchorage can solve monolithic extruded anchor connecting thread difficulty of processing, the problem that cost of manufacture is high, anchorage reliability is low.
In order to address the above problem, the technical solution adopted in the utility model is: this squash type composite entity dragline anchorage includes sphere backing plate and the Ball faced nut that leans against anchor plate one side, and being enclosed within many steel strand that Extruding spring and extruded sleeve are housed at termination point casing in monolithic extruded anchor cover, the termination of the core wire of described steel strand in described extruded sleeve has the little pier nose section of outer imperial palace; The profile of described extruded sleeve is positive six prisms; Described monolithic extruded anchor is sleeved in the support anchor ring of tubular, and the inner in described support anchor ring cylinder hole has been threaded connection clamp nut, is equipped with between described monolithic extruded anchor cover and described clamp nut and is enclosed within each root steel strand support backing plate outward; The outside of described support anchor ring is connected with described Ball faced nut by screw thread.
In the technical scheme of above-mentioned squash type composite entity dragline anchorage, technical scheme can also be more specifically: the outer end in described support anchor ring cylinder hole has been threaded connection the lifting nut; The outer face of described anchor plate is connected with protective cover; At described protective cover and described lifting nut, described support anchor ring is filled with anticorrosion grease between described Ball faced nut and described sphere backing plate; The inner of described support anchor ring is filled with epoxy mortar to the adapter sleeve that is enclosed within described steel strand outside is housed between the drag-line overcoat that includes many described steel strand in described adapter sleeve.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, the termination of the core wire of steel strand in extruded sleeve has the little pier nose section of outer imperial palace, can increase the friction of center presstressed reinforcing steel and peripheral presstressed reinforcing steel, improved the bond stress of extruded sleeve to presstressed reinforcing steel, guarantees the reliability of anchoring; The profile of extruded sleeve is positive six prisms, monolithic extruded anchor is sleeved in the support anchor ring of tubular, can make its inner crimping consolidation more, not only its to get its volume less, and can increase friction between extruded sleeve, thereby it is as a whole that it is combined into, to give full play to the mechanical property of each root steel strand; The inner in support anchor ring cylinder hole has been threaded connection clamp nut, be equipped with between monolithic extruded anchor cover and described clamp nut and be enclosed within the outer support backing plate of each root steel strand, not only can be balanced and the mechanical property of each root steel strand of performance, and can with the stressed support anchor ring that is delivered to of each root steel strand, these active forces be delivered on anchor plate by Ball faced nut, sphere backing plate by it.
2, the technical scheme of this squash type composite entity dragline anchorage is can implementation structure compact, external diameter is little, thereby the preformed hole size that this ground tackle is installed is reduced, increased presstressed reinforcing steel frictional force each other when realizing optimized integral structure, improve extruded sleeve to the bond stress of presstressed reinforcing steel, guaranteed the reliability of anchoring.
3, processing technology is simplified, and the external screw thread that supports anchor ring only needs to get final product with monolithic extruded anchor assembling after single processing, and need not the whole Shu Jiagong of special equipment, thereby can reduce cost of manufacture.
