The adjustable U-head jack for disc-lock scaffolding, also known as adjustable screw jack or threaded jack, is a core load-bearing accessory in the disc-lock scaffolding system. It achieves fine height adjustment through thread rotation, mainly used to support formwork, square timber and concrete pouring loads, adapts to the vertical pole connection of disc-lock scaffolding, and is widely applied in beam-slab support, full hall scaffolding erection and other scenarios in construction projects.

. Adjusting Nut: Equipped with a cross rotating handle for quick manual height adjustment, made of cast steel with high strength and good wear resistance.
. Screw Rod: Hot-rolled from Q235 or 45# steel, galvanized surface for rust prevention, high thread precision and smooth adjustment.
. Support Plate/Base Plate: Divided into U-shaped support (for bearing square timber/steel pipe) and flat base (for floor load-bearing), stamped from steel plate with firm welding.
. Connecting Sleeve: Precisely inserted into the vertical pole of disc-lock scaffolding to ensure connection stability.

. Height Adjustment: Fine adjustment within the range of 200mm - 600mm to meet different construction elevation requirements.
. Load Transfer: Evenly transfer the upper formwork and construction loads to the vertical poles of disc-lock scaffolding to ensure balanced stress.
. Construction Adaptation: Adapt to the standardized connection of disc-lock scaffolding, improve erection efficiency and reduce construction errors.
