Abstract [sv]

This is a degree project performed at Halmstad University in Sweden on the subject carpet of

reinforcement. This project is developed in association with Celsa Steel Service in Halmstad.

The purpose of this report is to investigate how much time that can be saved if carpet of

reinforcement is used instead of the traditional way to work with reinforcement and see

what kind of parameters that is important between the choices. We are also going to see

how this product affects the situation for reinforcement workers from an ergonomic point of

view.

Carpet of reinforcement is made by straight reinforcement’s bars that are welded together

with steel bands. These rolls are made at a factory with a machine that welds together the

bars in determined centre distance, with desired dimensions after the construction

engineers’ blueprints. The big advantage is that the work at the construction site becomes

much easier. Also the number of reinforcement workers and the total time of the project

can be reduced. All this together saves money.

The soft parameters like work environment are also affected in a good way. The rolls are

heavy and have to be lifted with a construction crane which saves the reinforcement iron

workers body. The traditional work with reinforcement involves a lot of heavy lifting and

trying work positions for the workers. Therefore is it fairly usual with wear injuries in the

trade. We think that carpets of reinforcement may reduce the amount of wear injuries. Most

of the workers that we interviewed seem to like the product.

There are two different products that Celsa Steel Service provides the trade with. Bamtec is

the oldest of these products and also the most common and appreciated. In connection with

building of bridges it is forbidden to weld together the reinforcement because of the risk of

fatique fractares in welded zones. Because of this, Bamtec can not be used in bridges. For

use in bridges a new product called SpinMaster, without welding, has been developed.

Carpet of reinforcement works best at large simple foundation slabs but can also be used in

walls.
