Although reinforcement configurations vary throughout each column project, the SKEW Jig-System offers a standardized assembly procedure that covers the assembly from straightforward to more complex columns.


Step 1: Positioning of standard stirrups.

Stirrups can be positioned in the teeth slots on a 25mm grid. Several markings are implemented in the SKEW Jig-System to visually show 5 and 10cm spacing. This makes exact positioning of stirrups fast and easy. For series, colored markers can be applied to the Jig-System to quickly identify stirrup positions.
Stirrups can have (multiple) inner stirrups, which in traditional steel fixing on trestles can dictate a specific assembly order. It is therefore recommended to bend a combined stirrups shape:
Traditional: Several individual stirrups.
Stirrup Proposal: 1 combined stirrup shape, directly from the bending machine

Step 2: Positioning of Console Stirrups and special reinforcement.

Often it can be difficult to add particular shapes when Bars are already in place. To make sure that particular console stirrups can easily be positioned, they can already be placed into the Jig-System, before adding the bars. Large lifting hooks, or special add-ins could also be positioned in this step, when positioning afterwards can be unpractical.

Step 3: Feeding main Bars.

A predetermined number of bars can be pushed through the stirrups. The use of rollers and the rebar bullet can smoothen this assembly step. Typically, the two bottom-corner bars are fed trough first.

Step 4: Fastening main Bars

When in position, the first bars are usually fastened to each individual stirrup. A skeleton shape of the column is formed.

Step 5: Feeding additional Bars.

Since the shape of the column is formed, additional bars can be added in preferred order. Again, the use of rollers and the rebar bullet will make this a smooth action.

Step 6: Fastening additional Bars

When dealing with many bars, the fastening choice can become significantly important in the overall assembly time.
The choice of fastening can later determine the amount of fastening points. For example, a tight traditional knot would be stronger than a tie made with a Tying gun. Yet a tack-weld can be steadier than a tied knot. Therefore, fewer welds are required than ties. And fewer handmade ties are required than tying gun ties.
It is recommended to set rules on the amount of fastening points that are required in the column configuration. For example, when dealing with 12 bars, the additional ten bars can be tied to only a small number of stirrups, while preserving a rigid element. Finding the best alternating tying and/or welding pattern will result in an optimal solution with the fewest amount of fastening points in a yet strong element.

Step 7: Fastening additional reinforcement / Consoles.

Once all bars are fastened, additional rebar can be tied in. Typically, these shapes include the ending U-stirrups on both console endings, and the remaining console-stirrups. Join-reinforcement, connection plates, lifting add-ins or anchors can typically be tied in afterwards.

Assembly speed.

Through a standardized work practice, unnecessary assembly steps are eliminated. On top, measuring, checking and do-over times are reduced to a bare minimum. Once implemented, workers can further streamline procedures trough division of roles, implementation of add-ons and goods supply and organization around the assembly stations.
During implementation, assembly time savings of 40-60% are measured, when following the assembly Steps. On top, by using Tying guns or Welding equipment, additional 10-20% savings are achievable.

SKEW JIG-SYSTEM: Column Assembly Steps


Do it yourself!
By taking the prefabrication of reinforcement into their own hands, Precast Plants and Contractors can quickly and effectively improve their overall manufacturing process. At the same time controlling the quality of the reinforcement and reducing the dependency on reinforcement element suppliers.
Quality Assurance and Control
When an order of reinforcement elements finally comes in and turns out to be substandard due to small flaws or inconsistencies or even larger deviations, the choices are to return, repair or completely redo the elements. None of these options are convenient for a busy company.
Short lead times are essential for the efficient operating of your business. With tight deadlines and not much room for error the last thing you want to be concerned with is meeting deadlines for delivery times on your project, the relationship with your supplier or unexpected additional costs. The adoption of your company’s standard by subcontractors is often preceded by a period of trial and error that comes at your expense.
When choosing to keep Quality Management and Quality Control in-house you gain the chance to further develop. Short lines of communication and frequent feedback within your organization will help you create a Continuous Improvement Cycle.
Planning and flexibility
Dependency on suppliers means relying on their adequate planning. Staying on top of your project when dealing with third parties, especially under the pressure of time, can be an enormous challenge. Working ahead not an option as reinforcement is often supplied in individual batches as and when they are completed.
Those Precast Plants and Contractors that manufacture themselves experience great freedom in planning and production flow: A controlled just-in-time delivery for the client and no more having to wait for a suppliers’ truck that is stuck in traffic. They get the benefits of being able to work ahead, spread the workload and easily meet their deadlines.
Cost savings
Having to pay for transport, commission, tooling and depreciation expenses of your supplier occasionally leads to an expensive total cost for pre-assembled reinforcement.
Standardizing your production process for your particular element portfolio can make you more efficient than your supplier. You can optimize the assembly procedure to your requirements. 
Where to start?
Ask yourself if the risks and the benefits of outsourcing are in balance. What are the benefits 
in relation to the advantages of manufacturing reinforcement yourself?
When starting, it is recommended to start with the production of a rather standard element. One welder or steel fixer can assemble a specific product(group) in a designated area. If you don’t have a cutting and bending capacity, this still can be outsourced. The in-house assembly of additional elements can be added over time. If the volume allows, the cutting and bending can also be considered to be done yourself, further increasing your dependency.

New Solutions for panels and tailored mesh!

Due to an increasing amount of requests concerning tailored mesh panels or bespoke mesh manufacturing in recent years, SKEW has been working on improved solutions for manual mesh welding lately.

Oftentimes the manual assembly of panels is actually faster and more cost effective than working with tailored, machine-manufactured mesh with later added rebar. We also see a reduction in the material used and a smaller manufacturing or stocking area when manufacturing manually.

By looking at shapes of reinforcement in more detail, loose bars regularly seem to give more options to optimize reinforcement.

These customer requests have now led to a larger digital library of Customizable Assembly Setups. A few examples of these can be found here. Based on typical reinforcement configurations, SKEW can quickly generate offers and part lists for your purposes.

These Setups are again easily customized to suit your specific needs, resulting in a high flexibility when working on the System.

SKEW has developed an improved grip system for the manual assembly of Pile Cages.
