The slope frame construction method null which uses the framework body and this framework body for slope frame formation

摘要

PURPOSE: To make it possible to easily form a firm grid slope frame by arranging frame bodies connecting plurality of inverted W-shaped lateral bars with a plurality of longitudinal bars in the shape of a grid, arranging reinforcing bars, and spraying mortar on them. ;CONSTITUTION: A plurality of inverted W-shaped lateral bars 11 in the front view are arranged, and leg bodies 11b are connected to each other with a plurality of longitudinal bars 12 to form lateral and longitudinal frame bodies 4 and 5. In addition, two reinforced installation materials equipped with lengthover the leg bodies 11b on both sides and reinforced installation sections 13c are so mounted at a proper interval in a loosely movable manner that they are positioned between a reinforced installation section 11c and slope faces A. Reinforcing bars 3 are arranged on a net-like body installed on the slope faces A in the shape of a grid at a specific pitch, and a plurality of frame bodies 4 and 5 are installed lengthwise and crosswise across the reinforcing bars 3. After that, the reinforcing bars 3 are lifted and is held with the reinforced installation sections 13c, another reinforcing bars 7 are arranged on the reinforced installation section 11c, and mortar, etc., are sprayed so as to bury the reinforcing bars 3 and 7 to form a grid slope frame.;COPYRIGHT: (C)1996,JPO
