Abstract
The invention provides a steel strand anchoring structure, and belongs to the field of anchoring devices. The anchoring device comprises an anchoring cup arranged at the outer periphery of a steel strand; a support nut for supporting the anchoring cup is arranged on the outer side of the anchoring cup; a clamping piece for tightly pressing the steel strand is arranged on the inner side of the anchoring cup; a protection pipe is arranged at the outer periphery of the steel strand between an anchoring disc and a base; and multiple reinforcing ribs are spirally distributed on the outer side of the protection pipe. The steel strand anchoring structure can adaptively adjust the prestress of the steel strand to prevent the prestress value change of the steel strand caused by stratum creep, steel looseness and structure change so as to enhance the stability of an anchoring system and to guarantee the safety and the stability of buildings and bridges.
Description
Technical field
The invention belongs to anchor device field, especially relate to a kind of steel strand anchoring structure.
Background technology
The advantage of prestress steel strand reinforced technological synthesis external prestressing strengthening technology, high strength steel strand reinforcing technique, it is a novel reinforcing technique, the high powerful feature of steel strand can be given full play to, but existing steel strand anchoring structure cannot carry out compliance adjustment to steel strand prestress, and cause steel strand prestress value to change due to the creep on stratum, steel are lax, structural change etc., cause anchoring body system to destroy, the safety and stability of building, bridge cannot be ensured.
Summary of the invention
In view of this, the present invention is intended to propose a kind of steel strand anchoring structure, to relax and structural change etc. causes anchoring body system that the problem destroyed occurs to solve due to the creep on stratum, steel.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of steel strand anchoring structure, comprise one next to be arranged and all L-shaped pedestal in longitudinal section and anchor dish, through hole is provided with in the middle part of the level board of described pedestal and anchor dish, steel strand one end is fixed on the level board of described anchor dish by fastening devices, and the described steel strand other end reaches below the level board of pedestal after passing the through hole on the level board of anchor dish and pedestal successively; The level board of described anchor dish is symmetrically arranged with two bolts hole, adjustment bolt passes described bolt hole from top and withstands the level board of pedestal, and the adjusting nut coordinated with adjustment bolt is arranged at the lower end of described anchor dish level board; The vertical plate of described pedestal is symmetrically arranged with two slotted holes, the vertical plate of described anchor dish is provided with the circular hole corresponding to described slotted hole, the vertical plate of described anchor dish and pedestal is fixed together through after described circular hole and slotted hole by fastening bolt.
Further, described fastening devices comprises the anchor cup being arranged at steel strand periphery, and described anchor cup arranged outside has the holding nut supporting described anchor cup, is provided with the intermediate plate compressed by steel strand inside described anchor cup.
Further, the steel strand periphery between described anchor dish and pedestal is provided with protection tube.
Further, the described protection tube arranged outside reinforcing rib that has several in spiral distribution.
Relative to prior art, steel strand anchoring structure of the present invention has following advantage: by adopting technique scheme, compliance adjustment can be carried out to the prestressing force of steel strand, avoid the steel strand prestress value change because the creep on stratum, steel relax, structural change etc. causes, thus strengthen the stability of anchoring body system, ensure the safety and stability of building, bridge.
