The type of anchor
is jm13-yn (jm13-yn) with good performance. Tension generally adopts through type jack.
Specifications and models are as follows: bjm15-n (bm15-n) or bjm13-n (bm13-n) (B, the first letter of flat anchor
in Chinese Pinyin, representing the meaning of flat anchorage); flat anchorage is mainly used for Transverse Prestress of bridge deck, hollow slab and low height box girder, so as to make stress distribution more uniform and reasonable and further reduce structural thickness.
The specification and model of (fixed end anchorage) are: jym15-n (ymp15-n) or jym13-n (ymp13-n); it is suitable for the situation of large design stress at the end or limited space at the end of the component. It is a kind of wrapped anchorage that uses an extruder to press the extrusion sleeve on the steel strand. It is embedded in the concrete and arranged as required. After the concrete solidifies to the design strength, it is tensioned.
