Perakitan kerucut pengikat dalam delapan ukuran dari M24D15 hingga M42D26,5, ditambah sarung formwork — penambat beban untuk formwork naik dan cantilever.
Formwork naik dan cantilever bergerak naik sepanjang dinding, sehingga kerucut harus menahan beban yang sama berulang kali dan melepaskan diri dengan bersih setiap kali. Seri ini mencakup perakitan kerucut empat bagian — baut kerucut, baut beban, batang screw, dan pelat dasar — dalam delapan ukuran, ditambah sarung yang menjaga lubang pengikat tetap bersih.
Koni + cangkang + set baut untuk sistem naik dan slipform, toleransi ±0,5 mm.
Climbing and cantilever formwork moves up the wall lift by lift, so the anchorage has to take the same load repeatedly and release cleanly every time. The four-piece tie cone assembly — cone nut, load bolt, screw rod and base plate — is cast into the wall, carries the form load, and then unscrews so the cone can be recovered and the hole plugged. A cone that binds or a thread that galls costs a shift on a climbing cycle, which is why the steel grade and thread finish matter more here than on a one-off pour.
Eight kit sizes span M24D15, M24D20, M30D15, M30D20, M36D20, M36D25, M42D25 and M42D26.5, with system tensile ratings from 140 kN on the M24D15 and M30D15 up to 380 kN on the M42D26.5. Cone and rod are 45# steel, the load bolt is class 10.9, and plate and sleeve are QT450-10 ductile iron. Choose the four-piece set where the sleeve is not needed and the five-piece set where the tie hole has to stay clear for the next lift. Match the D-number to the tie rod diameter used on the same form so one rod serves both systems.
Common sizes ship from stock in about three days; the larger M42 sizes and special plate dimensions take 7–15 days. Because a climbing system is ordered as a cycle set, we quote cones together with the matching rods and plates so the recovered parts and the new parts are dimensionally interchangeable lift after lift. Sets are packed by size in marked boxes — mixing sizes in one carton is the fastest way to stall a climbing cycle on site.
A formwork tie rod is a high-strength threaded bar that, together with nuts, anchor plates and walers, holds formwork panels against the lateral pressure of fresh concrete. It passes through the wall section and is either fully recovered after stripping (through-tie used with a sleeve) or permanently embedded (lost-end / water-stop type).
