CONNECTING STRUCTURE OF MID SUPPORTING BEAM FOR TEMPORARY SOIL SHEATHING WORK

摘要

A connection structure of a central strut under construction of a temporary retaining wall is provided to support earth pressure by forming a triangular bearing structure of the central strut, to cut down construction cost by reducing material, and to improve working efficiency by enlarging the work space. A central strut(100) is horizontally installed in excavating the ground, and an end of the central strut is integrally connected to a wale. A preloading jack(150) is installed in the central strut to connect plural central struts, and inclined beams(200) are inclined and integrally combined with first and second connectors(310,320) with a triangular bearing structure. The first connector is placed between left and right sides of the central strut and an end of the inclined beam, and composed of a vertical beam inserted between the central struts and support beams inclined and integrally connected outside the vertical beam. The second connector comprises a horizontal beam placed between the inclined beam and the wale and contacted to the wale, and connecting beams inclined and integrally combined with the triangular structure.
