BAMTEC Carpet Reinforcement
Steel bars utilized in BAMTEC carpet is conventional ribbed reinforcement which can be welded. Various bar diameter ranges from 8 mm to 32 mm can be used to construct BAMTEC carpet reinforcement. The BAMTEC carpet reinforcement can be transported to project site with up to 15 m in length and up to 35m is possible to roll out. The long and spacing of steel bars can be varied as per the requirements of the design. That is why BAMTEC carpet reinforcement can be employed for slabs with openings, non-rectangular slabs, and slabs on which different loadings are imposed. So, as it can be observed that the BAMTEC carpet reinforcement can be extremely complex that is why sophisticated design software with partially or completely automated production machine is needed to meet the requirements of the BAMTEC system. Steel bars in BAMTEC carpet reinforcement are kept in place or welded to small size steel strip.

Advantages of BAMTEC Carpet Reinforcement System
- This system is cost effective, because finite element analysis in which a detailing software is integrated and manufacturing robotics are combined in BAMTEC system, around 75% of materials employed in cut and bent reinforcement is needed in this system. This is because finite element curtailed prefabricated reinforcement is provided by the BAMTEC reinforcement system and eventually waste of material will largely decrease.
- Accuracy and quality is enhanced considerably
- Extremely fast construction
- Different bar diameter and spacing can be provided
- On-site checking of fixed reinforcement can be avoided
Design of BAMTEC Slab Reinforcement
There are number of software which can be used for the design of BAMTEC carpet reinforcement and most of and produce input data for the manufacturing machine. There are different methods to calculate forces act on the slabs, these forces will be used to compute reinforcement ratio for various regions of the slab. After that, the calculated reinforcement ratio is used by BAMTEC module and output BAMTEC carpet. Moreover, if the software which is used to estimate the reinforcement ratio is not integrated with BAMTEC module, then the designer must allocate specific amount of reinforcement for different parts of the slab based on the requirements of the slab. The plan for unrolling the carpet can be produced by software. An example of BAMTEC carpet reinforcement roll out plan, which is marked, is shown in Figure-3.

Production of BAMTEC Carpet Reinforcement
After the design and detailing of BAMTEC carpet reinforcement is finished by applying suitable design and detailing software, the BAMTEC carpet production machine, which is completely automated, is fed with out-of-design and detailing software data. So, the production of the BAMTEC carpet is carried out automatically which helps in placing reinforced steel bars at its position precisely. Moreover, the automated BAMTEC carpet machine can weld any specified bar diameter ranges from 8 mm to 32 mm and any steel bar length that can be from 1.7 m to 15m. It is possible to place different bar sizes with different spacing in one BAMTEC carpet. Different size of BAMTEC carpet reinforcement can be manufactured and maximum size is about 30m long and 15m breadth, and the weight of single carpet is up to 2 tones. Figure-4 and Figure-5 show BAMTEC carpet reinforcement machine which is fully automated.

Installation of BAMTEC Carpet Reinforcement
Installation of BAMTEC carpet reinforcement is considerably quick and need less labor compared with conventional reinforcement installation. Large carpet needs three or four worker whereas smaller carpet can be installed with only two workers with the help of cranes, and skilled labors are not required. It is estimated that 3-8 minutes are required to place a carpet disregard of the size and weight of the carpet. Therefore, it can be said that, BAMTEC carpet reinforcement is ten times quicker compare with the conventional method. The carpet installation steps include delivering the carpet to the project site, then the BAMTEC carpet is left to its position on the slab; the first bar in the carpet is placed at its exact location, and finally the carpet is rolled out.
