摘要： PROBLEM TO BE SOLVED: To provide a tapping screw constituted of a corrosion-resistant metal, which can be screwed into a hard base such as concrete or the like, and is manufactured easily, and also to provide its manufacturing method.
SOLUTION: The manufacturing method is characterized in that: a shaft 12 constituted by the corrosion-resistant metal, and at least single-start thread 13 integrally and at least partially constituted in the periphery of the shaft 12 are arranged; a plurality of small blades 22 constituted of a hard material is provided inside the thread 13, and the stiffness of the blade 22 is greater than that of the thread 13; the blade 22 is welded to the thread 13, preferably inside notch arranged in the thread; preferably the blade 22 is fixed to the thread 13 by electric resistance weld; the fixed blade 22 is at least partially projected from the thread 13 outward radially; and a mutual space A between the blades 22 is gradually enlarged in extending direction from a free end 14 of the shaft 12 to the thread 13.

摘要： PROBLEM TO BE SOLVED: To provide a self-tapping screw, in which insertion of the screw into a hard base is improved and which is easily produced.
SOLUTION: In the self-tapping screw 11 having a shaft 12, when a free end of the shaft 12 is a start point, a screw thread 21 is extended over at least a part of a shaft length, the screw thread 21 has cutting bodies 26, 36, 46, 56, 66 made of material higher in hardness than the thread screw 21, in cutouts 24 opened at least partially outside in a radial direction. Radially outer profiles 27, 37, 47, 57, 67 of the cutting bodies are at least partially projected from the screw thread. The height of the screw thread 21 is gradually reduced toward the free end of the shaft 12, and the heights A, B, C, D, E of the radially outer profiles of the cutting bodies are gradually decreased.

摘要： PROBLEM TO BE SOLVED: To provide a tap fixing element for a mineral structure, and a method for anchoring this. SOLUTION: In the method for anchoring, a structure 1 is formed with a hole 2 by a boring device, and then, the fixing element 11 is screwed into the formed hole 2. The fixing element 11 includes a rotation gripping means 16 for a driving tool, a shaft 12 having a valley diameter K and equipped with at least one cutting blade 21 at a first end area, and a tap screw where difference between the outer diameter A and the valley diameter K of the shaft 12 is 0.05-0.7 times as large as a pitch P. The boring device 101 has a boring-device-nominal-diameter of 0.95-1.10 times as large as the valley diameter K of the shaft 12. COPYRIGHT: (C)2011,JPO&INPIT
