<p>This is a degree project performed at Halmstad University in Sweden on the subject carpet of</p><p>reinforcement. This project is developed in association with Celsa Steel Service in Halmstad.</p><p>The purpose of this report is to investigate how much time that can be saved if carpet of</p><p>reinforcement is used instead of the traditional way to work with reinforcement and see</p><p>what kind of parameters that is important between the choices. We are also going to see</p><p>how this product affects the situation for reinforcement workers from an ergonomic point of</p><p>view.</p><p>Carpet of reinforcement is made by straight reinforcement’s bars that are welded together</p><p>with steel bands. These rolls are made at a factory with a machine that welds together the</p><p>bars in determined centre distance, with desired dimensions after the construction</p><p>engineers’ blueprints. The big advantage is that the work at the construction site becomes</p><p>much easier. Also the number of reinforcement workers and the total time of the project</p><p>can be reduced. All this together saves money.</p><p>The soft parameters like work environment are also affected in a good way. The rolls are</p><p>heavy and have to be lifted with a construction crane which saves the reinforcement iron</p><p>workers body. The traditional work with reinforcement involves a lot of heavy lifting and</p><p>trying work positions for the workers. Therefore is it fairly usual with wear injuries in the</p><p>trade. We think that carpets of reinforcement may reduce the amount of wear injuries. Most</p><p>of the workers that we interviewed seem to like the product.</p><p>There are two different products that Celsa Steel Service provides the trade with. Bamtec is</p><p>the oldest of these products and also the most common and appreciated. In connection with</p><p>building of bridges it is forbidden to weld together the reinforcement because of the risk of</p><p>fatique fractares in welded zones. Because of this, Bamtec can not be used in bridges. For</p><p>use in bridges a new product called SpinMaster, without welding, has been developed.</p><p>Carpet of reinforcement works best at large simple foundation slabs but can also be used in</p><p>walls.</p>
