Step by Step Guide

1. Design

Image

Option 1: Utilising the engineer’s initial design model, Hy-Ten can undertake a full slab design using our powerful finite element software (Sofistik). Our software also automatically details the reinforcement.

Once the design and detailing have been checked and approved, our software produces schedules that are transferred electronically to one of our Bamtec manufacturing robots.

The combination of powerful F.E.design, integrated detailing, fully automated carpet manufacture plus the inclusion of our unique non-standard bar diameters (14,18,22mm) means Hy-Ten can supply complex reinforcement configurations that give up to 35% materialsavings over standardized cut and bent reinforcement. It also means fast, cost efficient and accurate design and detailing.

Hy-Ten include the cost of design and detailing in the Bamtec cost / tonne. Accordingly, utilizing this option allows engineers / customers to enjoy free design and detailing.

Option 2: Hy-Ten can redetail the existing cut and bent configuration to suit Bamtec. This option does not provide material savings, but does enable customers to benefit from the speed with which Bamtec can be installed.

2. Manufacture

Image

Hy-Ten manufacture Bamtec at Bootle in Liverpool and Wallingford in Oxfordshire. In total Hy-Ten currently has 4 Bamtec manufacturing robots.

Operating both from coil and stock bar, the robots weld standard CARES approved reinforcement bars to continuous 1mm thick metal strips at 1.5 metre centres to produce the Bamtec carpets that will be rolled out on site.

The Bamtec robots can weld any bar diameter required from 8mm to 32mm (including our unique non-standard diameters - 14, 18, 22mm) and any bar length required from 1.7 metres to 15metres. The bars within each carpet can be of varying diameter and length and at varying centres and positions relative to one another. Carpets can be of varying size (up to 15 metres wide and 30 metres long) and of varying weight (up to 2 tonnes).

This versatility allows us to supply very complex and variable reinforcement configurations for a multitude of construction applications in carpets that are quickly and easily rolled out on site.

Furthermore, the process is fully automated, the robots working to information transferred from our Sofistik design and detailing software, thereby ensuring that the bars are positioned in exactly the configuration required by the engineer's design.

3. Installation

The installation of Bamtec carpets is substantially quicker and requires fewer site personnel than the fixing of traditional reinforcement, resulting in reduced fixing costs and shorter site programmes.

All the carpets arrive on site pre-slung for easy off loading and site movement.

Instead of the time consuming traditional method of positioning and tieing each individual reinforcement bar, Bamtec carpets (incorporating bars already welded in the correct position relative to each other) are moved into starting position by crane and then simply rolled out. The carpets do not need to be tied to one another.

Hy-Ten can provide couplers on internal column bars at soffit level. This means that columns are not an obstruction to the rolling of carpets. This enables us to supply larger and fewer carpets, thereby speeding up the installation process.

Hy-Ten design and produce shear rails which can be used in conjunction with Bamtec to further improve the rate of construction.

A typical time saving from the use of Bamtec in a concrete frame building is two thirds of the time foreach pour of the equivalent slab fixed in loose bar.

To assist installation, Hy-Ten provide site personnel with a rollout plan and an overview plan. The rollout plan shows the exact position and rollout direction of each carpet.
