A prefabricated earth retaining structure for construction is provided to protect a lagging board against earth pressure and to have a strong support structure by fixing H-beams and a lagging board using steel bars strongly and fixing a lagging board using connection members. The prefabricated earth retaining structure for construction comprises an H-beam(30) unified with many support brackets(31), a lagging board(40) provided with many coupling holes(41) and many bolt grooves(42), a connection member(50) composed of a horizontal stiffening plate(51) provided with four coupling pins projected to the top and bottom and a vertical support plate(53) placed perpendicular to the widthwise side of the horizontal stiffening plate and provided with a support bracket(55), and a steel bar(70) fastened to the support brackets of the H-beam and the connection member by nuts(N). |
