Features of Hydraulic Core Hollow Jack
1. YDC Types Stressing jack is a general-purpose prestressed
through-heart jack, which is used for tensioning operations of
various steel strand anchorages. Widely used in post-tensioning
large buildings, structures, prestressed concrete bridges, rock
anchoring, hydraulic structures, foundation anchoring, and other
major projects.
2. The main parts of the jack are made of high-strength steel,
which has the characteristics of compact structure, lightweight,
small volume, short axial length, and short reserved tension length
of steel strand, which can save steel strand material. And the
hoisting is flexible, durable, easy to operate, and easy to
maintain.
3. YDC type jack is a kind of feed-through jack, which is a
multi-purpose prestressed tensioning equipment. It is easy to
operate, mainly used for single-hole tensioning, and can also be
used for long and short preloading. Tensioning and troubleshooting,
and suitable for high-strength steel wire bundles and strands of
various specifications.
Installation of Post-Tension Jack and Anchorage
1. The steel strand shall be threaded into the reserved gallery of the structure, and the exposed length of the steel strand at the tensioning end is required to be 200-250mm longer than the working length of the jack. The steel strand must be cut with a thin disc grinder without loose ends or "rough ends" to avoid difficult perforation.
2. Cover the end of the steel wire bundle of the working anchor plate, push it to the anchor base plate, and align it with the spigot.
3. Installation of working anchor clips: before installing clips, use steel rings to clamp each pair of clips together, then push them into the taper hole of the anchor plate along the steel strand, and then push them until they do not move.
4. Installation of limit plate: the limit plate is designed according to the working anchor plate and matched with the hole of the anchor plate.
5. Installation of jack: first bind the end of the steel strand bundle with a wire pin, then lift the jack and put it on the steel strand, and put the support opening of the front cover of the jack on the outside of the limit plate. At this time, the jack can be coaxially aligned.
6. Install the tool anchor on the support lip at the end of the piston.
YCWB series cross-core light jacks YCWB series jack - the generation IV new type and light jack successfully introduced by us on the basis of YCWE series jack and further improved and optimized by us on structure and size. It has a small volume, light weight, good sealing performance, high strength and reliability, and strong universality, and it is the updated product for the jack. It is widely used in post-tensioning prestressing construction. Supported with different accessories, it can tension M clamping piece group Anchor and various clamping piece group Anchors as well as DM button-head Anchor and cool cast Anchor.
