PURPOSE:To raise the workability of slope frame construction by a method in which expanded plastic pieces are fixed to the sloped ground along the undulation of the slope to form a polygonal formwork and cement mortar, etc., is placed into the apertures of the formwork to form the slope frame. CONSTITUTION:A formwork 1 of a square form without corners is built up by combining four expanded plastic pieces 2 of a planar view bent form. Afterwards, in the constructing stage of a slope frame 5, a framed structure of reinforcing bars is set, and then cement concrete or mortar is sprayed. The pieces 2 are fixed to the sloped ground by driving piles 8 inserted into the fittings 7 of the pieces 2 into the ground. The slope frame having high heat insulating property, high water holding capacity, and sufficient strength can be very easily constructed along the undulation of the slope with excellent workability because of the light weight of the frame materials.
