Rullarmering : Att adoptera en armeringsmetod

Sammanfattning: Rebar carpet is an innovation that favors the working environment of the rebar workers and saves time. Reinforcement workers today are a vulnerable group. Heavy lifts and backbreaking postures are a part of their everyday work. It is already established that work with rebar carpets is both time-saving, economically beneficial and from a working environment point of view better than traditional reinforcement work. Despite all benefits it is used in rather few projects today. The purpose of this study is to identify how the construction industry embraces new innovations related to in situ concrete with post-tensioned reinforcement. The goals are to find out how designers, contractors and manufacturers are working to adopt rebar carpets in the construction process and to shed light on, factors affecting the adoption. The study is based on semi-structured interviews with designers, contractors and a representative of a rebar manufacturing company. Designers and contractors have not, generally speaking, been actively working to adopt rebar carpet. The governing factors for the use of rebar carpets is the designers and contractors knowledge and previous experience of rebar carpet. The contractors who have previous experience of rebar carpet can imagine using rebar carpet again and contractors with no previous experience believe that they need more knowledge of rebar carpet before they dare to try. Design engineers who have designed for rebar carpet before has it in mind when they design other projects. Designers who have no previous experience of rebar carpet demand more knowledge about how they can facilitate the use of rebar carpet.
