U-Head Screw Jack

The core function of U-Head Screw Jack is to provide stable and adjustable support.It adjusts the height of the U-shaped pallet by rotating the lead screw,so as to accurately support or lift the structures that need support,such as concrete formwork,steel pipes,wooden flutes,etc.

It is mainly composed of the following parts:

U-shaped pallet(U-shaped pallet):a component that directly bears the support(e.g.steel pipe,wooden square).Its unique U-shaped design effectively prevents the support from slipping laterally.

Lead screw:The transmission component of the core.By rotating the lead screw,the lifting and lowering of the U-shaped pallet can be precisely adjusted,allowing for the adjustment of the support height.

Adjustment nut or adjuster:Put on the lead screw.Rotate it to drive the lead screw to lift and lower,and some designs adjust directly by rotating the lead screw itself.

Other components:depending on the design,it may also include stiffener,connecting disc 1,reducer mechanism(for adapting to different diameter support pipes)1,etc.

Features&Benefits:

Top support lead screws with U-shaped pallets have the following features:

Support Stability:U-shaped pallets can effectively limit the horizontal movement of supports,prevent slipping,and enhance the safety and stability of the overall support system.

Height Adjustable:Precise height fine-tuning can be achieved by rotating the lead screw or adjustment nut,adapting to different construction height requirements and relatively easy to operate.

Strong load-bearing capacity:Mostly made of Q235 steel and other materials,and through stiffeners,reinforcement ribs and other designs to ensure that it can withstand large loads.

Durable and high turnover:The surface of many top screws will be treated with hot-dip galvanization and other treatments,which are rust-resistant and wear-resistant,which can extend the service life and is suitable for multiple turnarounds.

Shock absorption and noise reduction(partial design):Some improved toppers also add springs and other cushioning devices,which can absorb vibration during partial construction,reduce noise,and reduce the potential harm of vibration to the support structure.

Main application scenarios

This type of top support screw is widely used in formwork support systems on building construction sites,such as:

The main or secondary beam supports the horizontal formwork system.

For use at the top or bottom of the scaffolding system,providing adjustable support points.

It is suitable for formwork support of floors,beams,columns and other structures of cast-in-place concrete.
