Berpais AJ 01 armor seam

  The expansion joint system consists of two pieces of galvanized steel plates with edge protection joints, which are fixed together by easily broken plastic bolts. Each steel plate has rectangular holes distributed at a certain distance on both sides, which are bent to form continuous anchors to ensure a firm connection with the concrete. When the steel plate is bent, a 15mm horizontal surface is formed on each side to protect the concrete from damage; At the same time, the system is equipped with rectangular transmission plates and expansion sleeves; After the installation of the system, each compartment block on the floor can freely expand and contract in both vertical and horizontal directions to avoid the formation of cracks.
