Structure for connecting and jointing square still supporting beam in temporary soil sheathing and reinforcing members for the same

PURPOSE: A structure for connecting and joining square steel pipe for temporary sheathing construction and connecting/welding reinforcement members for the same are provided to facilitate connection and disassembly of struts in an installation place, since one end of a strut to be connected is placed on a connecting reinforcement member. CONSTITUTION: A structure for connecting and joining square steel pipe strut(10) for temporary sheathing construction comprises following steps. Square steel pipe struts are connected to each other by connecting reinforcement members(20) in ground drilling. The connected square steel pipe strut is welded with a wale or a jack support through a welding reinforcement member. An insertion portion is formed on one side of the welding reinforcement member for the insertion of the end of the square steel pipe strut, and a coupling plate, which is welded with the wale or the jack support, is formed on the other side of the welding reinforcement member. A support partition plate and the reinforcing member are connected between the insertion portion and the coupling plate. The support partition plate is fixed to one side of the insertion portion.
