Cuplock System Scaffold Complete Guide

What is Cuplock System

Scaffolding is a temporary structure used for construction support and framing. It is also called staging. Strong and sturdy are the most important for construction safety.

Cuplock Scaffolding is one type of scaffold. Compare to traditional tube and coupler type of scaffolding, cuplock is a modular scaffolding with systematic steel components and parts. The systematic cuplock parts are pre-engineered with node-locking devices welded. Cuplock standard with the welded fixed bottom cup. Allows 4 components(for example ledgers) to connect from four directions. The top cup of the standards covers the components in place. A hammer is the only tool used to make the node connection firmly fixed.

Features of Cuplock Scaffolding

Simple To Use 

Cuplock scaffolding parts are designed with specified sizes with welded node locking devices. Workers just need to make them connected and formed by a hammer. Very simple and easy to erect and disassemble.

Safety For Construction

Cuplock scaffolding is made of a 3.2mm scaffold in S355 steel grade. The high yield and tensile strength steel ensure cuplock scaffold material with high load capacity.

Fixed bottom cup are made from 5mm steel plates. Very strong to take all loads from cuplock ledgers, and braces.

Drop-forged top cups slide over to cover the cuplock ledger blades. Rotate the top cup to make the ledger blades covered safely and firmly.

Forged top cups can take all hits from hammers. Make the cuplock system stable without any moving and losing.

Easy to Handle

Cuplock scaffolds use high grade steel but less weight. Compare to traditional type 4 scaffolding pipes. It is lighter 20% lighter. Easy to handle in construction. Cuplock materials are packed in steel pallets. Easy to transit by forklift.

Save Time and Cost

Simple in erection, easy handling. Cuplock can short 30%-50% of time in scaffold construction.

The light weight makes the cuplock cheaper in cost too.

Hot dip galvanized finish gives the cuplock a longer life more than 10 years. Using cuplock scaffold save you cost in the short and long term.

Flexible Application 

Cuplock scaffolding system is able to form all shapes of scaffold and staging for construction which traditional scaffold is hard to arrange. With cuplock cantilever frames and brackets, cuplock scaffold is easy to support concrete slabs and beams beyond the main scaffold framing too.

In addition, using cuplok is easy to form any mobile scaffolding, staircase towers, and birdcages for internal and external construction.

Wellmade Cuplock Scaffolding major application:

1. Facade Scaffolding
2. Formwork Support
3. Birdcages
4. Maintenance Access
5. Stair Access
6. Mobile Scaffolding
7. Handrail and Edge Protection

Cuplock Scaffolding Construction Height

1. Single (putlog) Scaffold Height: 24m
2. Double Scaffolding Height: 50m
3. Cantilever Scaffold Height: 20m
4. Full Framing Scaffold Height: 30m

In construction, cuplock scaffolding needs to be anchored to fixed buildings and structures for safety purposes by anchor tubes and eye bolts.

When the cuplock scaffolding construction height is more than 40 meters, needs a professional design and safety calculation to arrange the cuplock bearing the required weight.

Cuplock Scaffolding Node Locking Devices Arrangement

All cuplock scaffolding components are with distinguished locking devices welded or riveted on.

• Cuplock standards are welded with node locking devices of top cups and bottom cups. The cups are welded at every 500mm intervals.

The quantity of the cups for each size of the standards is in the following table.

Cuplock Standard SizeCups Quantity0.5m Standard11.0m Standard21.5m Standard32.0m Standard42.5m Standard53.0m Standard63.5m Standard74.0m Standard8

• Cuplock ledges are welded with two ledger blades at two ends of the scaffold horizontal tubes.   The ledger blades are inserted into the bottom cups of the cuplock standards, which are welded and fixed on the cuplock standards.

The ledger blades will be covered by the top cup of each node after being inserted into the bottom cup. The top cups are slidable and can be rotated to cover the ledger blades in position. One set of bottom and top cups can fix four ledger blades at the same time. So the cuplock scaffold allows 4 directions of cuplock ledger connection at each node.

• Cuplock scaffolding diagonal braces node locking devices can be three different types: half swivel clamps, swivel blades snap on locks.

The brace locking devices are fixed at both ends of the brace tubes by strong rivets. They are connected to the standard cups or fixed to standard main tubes.

• Cuplock steel planks with hooks. They can easily move from one level to another level without tightening and loosing the board clamps.

While if using cuplock hop-up transoms and hop-up brackets in construction, steel or timber plank without hooks (with plain ends) can be easily arranged between different platform levels.
