Scaffold U-Head Jack

Scaffold U-Head Jack: Professional Load-Bearing Support Solution

Shandong Xingrui Building Materials Co., Ltd. delivers industrial-grade Scaffold U-Head Jack systems engineered from Q235 premium steel for demanding construction environments. Manufactured in our 79,800 square meter facility with 12 welding robots and 6 automatic welding lines, each unit features a Φ32/36mm precision screw, 120×120mm support plate, and 350mm adjustment stroke. Our product achieves precise elevation control for formwork primary and secondary walers, tested under ISO 9001 certified quality protocols by 180 professional technicians. With load-bearing capacity validated through full-process tracking systems, these reusable components distribute formwork pressure efficiently while maintaining structural integrity across variable floor heights.

Core Functions and Applications

Your construction projects require reliable top-support accessories that handle extreme vertical loads. The product serves as the critical interface between scaffolding standards and horizontal shoring members in three high-priority scenarios.

For high-rise concrete formwork, it supports H20 timber beams or aluminum beams under heavy slabs. The U-shaped groove prevents lateral movement of primary beams, reducing collapse risks during concrete pouring. The large support plate disperses concentrated loads across scaffolding nodes.

In infrastructure bridge shoring, these jacks endure vibrating environments during pier construction. The extended adjustable screw accommodates diverse girder heights while lock nuts secure positioning under dynamic loads.

Industrial plant maintenance operations benefit from the U-shape's ability to cradle irregular piping components. This design flexibility makes it indispensable for refinery turnaround projects where standard flat jacks cannot safely secure overhead systems.

Technical Specifications of Scaffold U-Head Jack

Manufacturing Excellence

Our cold bending workshop and steel casting facility produce components that meet EN 12811-1 standards. The welding workshop employs CO2 shielded full-penetration welding between threaded stems and U-plates, ensuring zero detachment under stress.

Each Scaffold U-Head Jack undergoes real-time quality tracking from raw material selection to finished product testing. The forging workshop utilizes 5 semi-automatic lines to maintain grain flow in threads, maximizing shear strength compared to cut-thread alternatives.

Surface treatments in our electrostatic spraying workshop provide corrosion resistance for 5-10 year service life. Hot-dip galvanization options deliver 60-80 microns zinc coating for coastal or high-moisture environments.

Quality Assurance Process

You receive products backed by complete traceability systems. Our inspection protocol verifies four critical safety benchmarks before shipment.

Weld penetration testing confirms structural integrity through macro-etching analysis. Thread tolerance checks ensure smooth nut movement with minimal lateral play, preventing seizure under pressure.

Ultimate load testing validates safe working loads per international standards. Magnetic gauges measure galvanization thickness to guarantee rust-resistant thread performance in harsh conditions.

ISO 14001 environmental certification ensures manufacturing processes meet sustainability requirements. ISO 45001 occupational health standards protect the 920-person workforce producing your scaffolding solutions.

Installation and Safety Guidelines

Maintain at least 150mm or 25% of total stem length inside the vertical standard for structural stability. This insertion depth prevents buckling when supporting formwork loads.

Clean threads after concrete exposure and apply lubrication before reuse. Discard units with compromised thread profiles or bent stems to maintain jobsite safety standards.

The ductile cast iron handle withstands hammer-adjustment impacts without cracking. Lock nuts secure elevation settings, acting as force-transferring accessories between vertical supports and horizontal beams.

The extended screw design fits various floor heights while the U-groove securely positions main and secondary ribs. This eliminates beam slippage during concrete pouring operations.

FAQ

Q：What differentiates solid and hollow stem versions?

A：Solid stems deliver higher load capacity for heavy shoring applications. Hollow stems reduce weight and cost for standard slab support projects without compromising safety margins.

Q：How do I select appropriate surface treatment?

A：Choose electro-galvanization for dry indoor projects. Opt for hot-dip galvanized finishes when facing outdoor moisture exposure or long-term infrastructure installations.

Q：Can jacks be reused after concrete contact?

A：Yes, provided you clean and lubricate threads immediately. Regular maintenance extends service life beyond typical project durations.

Q：Why specify roll-threaded over cut-threaded stems?

A：Roll-threading preserves steel grain flow, creating 30% higher shear strength. This manufacturing method prevents thread stripping under cyclical loading.

Q：What minimum insertion depth ensures safety?

A：International standards require 150mm minimum engagement or 25% of total stem length inside scaffold tubes to prevent pullout failures.
