Connection systems for reinforcement mesh

A connecting system for connecting first and second mesh sheets each defining a plurality of longitudinal members at least one pin housing, a first pin member, and a second pin member. A first loop portion is formed on at least one of the plurality of longitudinal members of the first mesh sheet. A second loop portion is formed on at least one of the plurality of longitudinal members of the second mesh sheet. At least one pin housing defines a loop passageway, and the first and second loop portions extend in opposite directions through the loop passageway. The first pin member is arranged between the first loop portion and the at least one pin housing. The second pin member is arranged between the second loop portion and the at least one pin housing. Loads that displace the first and second mesh sheets away from each other are transferred between the mesh sheets by the pin housing and the first and second pin members.
