Summary of the invention
According to background technology, it is compact more on a kind of structural entity that the purpose of this utility model is to provide, in the whole waterproof of anchored end steel strand, further strengthened water resistance, anchored end in the new type of compression dispersion-type prestressed anchorage cable that bore diameter further reduces.
To achieve these goals, the utility model is achieved through the following technical solutions:
Anchored end in a kind of new type of compression dispersion-type prestressed anchorage cable, mainly by fixed end drag-line (1), anchor head (2) in the anchor cable, skull (3), cover plate (4), hold-down screw (5), O RunddichtringO (6) is formed, wherein: anchor head (2) cross-under together in the endoporus (21) of fixed end drag-line (1) by anchor head (2) in the anchor cable and the anchor cable, make fixed end drag-line (1) and anchor cable interior anchor head (2) form an integral body by hold-down screw (5) with the head that makes cover plate (4) be pressed on fixed end drag-line (1) that is connected of the interior anchor head (2) of anchor cable by cover plate (4), skull (3) is by the head nut (31) of skull (3), the bottom thread (32) of skull (3) and the anchor head screw thread (22) of the interior anchor head (2) of anchor cable are spirally connected, and compress O RunddichtringO (6).
Owing to adopted technique scheme, the utlity model has following advantage and effect:
1, structure of the present utility model is simpler, and more integration is compacter, can further reduce bore diameter, has also simplified assembly technology simultaneously, makes it cheap for manufacturing cost, can reduce the cost of a large amount of use prestress anchorage cables.
2, the utility model by single steel strand waterproof, changes in the whole waterproof of anchored end steel strand on the structure, has further strengthened water resistance, and total length adopted corrosion protection, and working service is repaired simple and easy.
