PURPOSE:To conserve labor and power as well as to shorten the period of construction by a method in which vertical beams are joined with couplers by rigidconnection and horizontal beams are connected to the couplers by hinge. CONSTITUTION:Four bracket 17 are welded to the facing sides of a coupler body 16, and an intermediate coupler 18 is connected through a shaft 19 vertical to slope to the horizontal beam connection 17a. A vertical beam 12 is fixed to the vertical beam connection 17b by bolts 21 to form a slope frame structure. Since the beam 11 and the coupler 13 are connected universally, the structure can easily follow the undulation of sloped ground and the curving of the slope sides, labor saving is attained and construction period can be curtailed.
