摘要： PROBLEM TO BE SOLVED: To provide a burial construction method for a formwork member capable of easily and securely installing the formwork member such as a formwork for a drain groove or an angular member for forming a concrete joint at a specified level, and an anchor member used therein. SOLUTION: A roughly cross-shaped anchor member 7 provided with a protruded part 9 is driven into a bottom plate 5a of a groove 5, and as a drain groove member 2 is supported by the anchor member 7, concrete is placed into the groove 5. In welding the anchor member 7 with a support bracket 10, an upper part 8a of an anchor main body 8 of the anchor member 7 is bent when their crossing part A is in a fused condition.

摘要： PURPOSE:To produce a waste water ditch having an optional depth with the thrust bending work of a metallic plate, by bending both side plates at obtuse angles in the same direction to a bottom plate and bending the center of the bottom plate at an obtuse angle to make both side plates parallel approximately. CONSTITUTION:A metallic plate 7 is put on a die 16, and a bending line 8 is placed on a V-shaped groove 17 having an obtuse angle, and the metallic plate 7 is subjected to the thrust bending work due to a punch 18. Then, the first side plate 10 is bent at an obtuse angle as shown by the two-dot broken line. Similarly, a bending line 9 of the metallic plate 7 is placed on the groove 17, and the second side plate 11 is bent by the thrust bending work due to the punch 18. The bent metallic plate 7 is put on another die 19, and a bending line 13 is placed on a V-shaped groove 20 having an obtuse angle, and the metallic plate 7 is subjected to the thrust bending work due to a punch 21 to make side plates 10 and 11 parallel approximately as shown by the two-dot broken line. Edges of side plates 10 and 11 are bent at right angles to the outside in positions of bending lines 14 to form flange parts 15.
