The following is picture of prestressing work for bridge construction
Post-Tension in bridge construction is usually taken tensioning from two sides(one side is stressing-end, and the other side is dead end).
First, installation of stressing end anchor system
Second, installation of dead end anchor system
Use GYJ500A Compression Making Machine for making P Type Dead End Anchor
P Type Dead End Anchor Before Extrusion
P Type Dead End Anchor After Extrusion
Sometimes will use 5mm, 7mm, 9mm diameter pc steel wire and 18mm, 25mm, 28mm, 32mm steel rebar anchor in prestressing work. PC steel wire is also used in prestressed concrete work such as precast factory, hollow core slab, concrete pole, concrete column, etc.PC Steel Wire is used tensioned by monostrand jack such as QYC270 monostrand jack, YDC240(24 tons) monostrand jack, etc. We also supply power pack(stressed pump) for monostrand stressing work.
The steel rebar anchor is mostly used in bridges construction and buildings construction, the steel bar anchor system including: screw nuts, steel bar, anchor bearing plate, spiral reinforcing ring.
