CUPLOCK (CUPLOK) SCAFFOLDING SYSTEMS

Cuplock Scaffolding System

Original designed and invented by SGB Company with exceptional safety margins, the Cuplock Scaffolding System (also called CUPLOK) is a multifunctional modular steel pipe scaffolding system.

Reasonable node joint structure, simple Manufacturing Process, easy and quick erection, especially widely construction application, which can fully meet the construction requirements of buildings such as houses, bridges, tunnels, chimneys, and water towers.

Compared with the traditional type of Pipe & Couplers scaffold, the Cuplock System scaffolding has the broad development and application prospects all over the world.

   DURA’s Cuplock Scaffoldings supply for the construction of Palm Jumeirah, Dubai.

  • DURA Cuplock Scaffolding is a multi-purpose steel scaffolding system for all access, shoring and supporting vertical loads.

  • The Cuplock Scaffolding is different from Ringlock Rosette connection scaffold which is welded a fixed BOTTOM CUP metal accessory as the node points that can lock up four base components in one hammer blow provide a wider range of applications.

  • Node points are spaced on all standards at 500mm intervals to ensure that correct working lifts can be provided and handrails are positioned at the correct height. Four components are secured in one action ensuring the system is faster to erect than traditional methods.

  • Cuplock Standard (Vertical), Ledger ( Horizontal), Diagonal Brace, Intermediate Transom, Steel Planks, Omega Transom, Hop up Bracket, Steel Ladder, Universal Jack/Base Plate/Fixed Forkheads are the mainly parts of this scaffolding system.

  • The round sockets are welded on a certain length of steel pipe every 0.5m called vertical, connecting with Ledger and Diagonal brace, bottom supported by Base Jack to set up a system

Cuplock Scaffolding System Introduction & Application

Operation Principle

The Cuplock scaffolding is a kind of scaffolding with using a creative design” Cup” as node points. It is only needed to be welded fixed bottom cup and pre-installed movable Top Cup on the Vertical pole, inserted horizontal ledger with welded pins between two Cup node points without any scattered accessories such as bolts, nuts, and plugs.

The Cup Node points are spaced on all standards at 500mm intervals to ensure that correct working lifts can be provided and handrails are positioned at the correct height. Four components are secured in one action ensuring the system is faster to erect than traditional methods.

System Cuplock Features

It has the advantages of rapid disassembly, labor-saving, stable and reliable structure, complete equipment, strong versatility, large bearing capacity, safe and reliable, easy to process, not easy to lose, easy to manage, easy to transport, and widely used. It has greatly enhanced the work effectiveness

Surface Treatment & Application Life

According to the requirement clients, our company DURA SCAFFOLD can supply surface treatment of Painting, Powder Coated, Electro-Galvanized, and Hot-dip Galvanized.

  1. Painting service life: 1 year in the dry construction environment
  2. Powder Coated service life: 2-3 years in the dry construction environment
  3. Electro-Galvanized service life: 2-3 years in the dry construction environment

Main Feature of Cuplock System Scaffolding

Components’ Size & Weight of DURA Cuplock System

The basic structural components of the Cuplock scaffolding system are Vertical Poles(Standards), Horizontal Ledgers, Diagonal Braces, Jack Bases, Steel Planks, etc. The auxiliary accessories include Intermediate Transom, Inside Intermediate Transoms, Omega Transom, Hop-Up Bracket, Omega Hop-Up Bracket, Steel Ladder, Stairways, etc.

Cuplock Standards/Verticals

These items from the Vertical Members of the scaffolding are made from Q345B high tensile steel tube with a size Diameter 48.3mm X thickness 3.25mm. The standard includes a fixed bottom cup which is welded at 500mm intervals, with a movable top cup that can secure up to four components.

These cups are the fixing node points for the horizontal ledgers, hop-up brackets, transoms, and ancillary items. At the top of the standard usually comes with Spigot that allows the further connection with other standards.

At the bottom of the standard, there is a corresponding drilled hole to allow below standards to be bolted together.

Cuplock Horizontals Ledgers

These are horizontal members that from the ledgers of the Cuplock system.

They are made of diameter 48.3mmX3.0mm thickness steel tubes, which are welded forged blades both ends so that can be inserted into the Cup nodes of the standards completely.

As the basic parts of the Cuplock scaffolding system, it’s simple, easy and quick to assemble. It can also be served as a guardrail in staircase towers.

Sizes are the following standard sizes, also can be designed and customized as requirements.

Diagonal Braces

The Dura Cuplock Diagonal Brace has three styles to form the oblique connection systems. The brace comes in different lengths to suit combined ledger sizes and standard heights.

Braces end can be made usual swivel forged blade or half couplers, and snap s, which all allowed to be connected on Standard.

Three styles:

  • Swivel Blade Face Brace;
  • Swivel Clamp Brace;
  • Snap to Snap Brace;
