PROBLEM TO BE SOLVED: To provide a simple method of firmly anchoring wire netting to a frame body made of steel or the like without using special skill or a special device in the wire netting formed by longitudinally and laterally combining spiral wires. SOLUTION: In this end fixing structure of wire netting 1 formed by longitudinally and laterally combining spiral steel wires, the longitudinal wire 14 and lateral wire 15a at the end of the wire netting 1 are clamped using two clamping hardware members formed of strip-like flat steel 2, L-shaped steel 2a, or the like and fastened by a bolt 3 and a nut 4 passing through the clamping hardware members. At least one lateral wire 15a parallel with the clamping hardware members is arranged on the end side of the longitudinal wire 14 rather than the bolt 3. The bolt 3 is thereby inserted through a mesh 5 formed by the lateral wire 15a and the longitudinal wire 14. Further, the end on the outside of the lateral wire arranged on the outside of the bolt in the longitudinal wire 14 intersecting in a right-angled direction to the lateral wire 15a is bent over a predetermined length to provide a bent part 9, and the bent part 9 is clamped by two clamping hardware members.

PROBLEM TO BE SOLVED: To provide an apparatus capable of freely supplying a spiral wire material having an optional pitch in the longitudinal direction of the wire material and a spiral radius within a face right-angled to the pitch. SOLUTION: The apparatus comprises two stages of front stage and rear stage. Each pass line of the front and rear stages includes a die section having an angle to each other and a workpiece forcing means placed at the entrance of the front stage for forcing the wire material in the direction of the pass line of the front stage. The die section of the front stage has a cylindrical die section proper 21 of the front stage which introduces the wire material 1, a housing 25 which is placed around the outer periphery of the cylindrical die section proper 21 and is free to turn, a plurality of front stage roller dies 24 which are fitted to the housing 25 and are free to rotate at the fixed positions, and a front stage turning means which turns the housing 25. The die section of the rear stage includes a hole die 31d which is fitted to the housing and guides the wire material and a pass line angle adjusting means. The pass line angle adjusting means which is fitted to the housing and is free to swing includes a lever 32a fitted with the hole die and an operating section 32c which is capable of adjusting the angle of the lever.

PROBLEM TO BE SOLVED: To exhibit an excellent shock-absorbing performance while enabling an efficient and simple construction. SOLUTION: A prevention fence for falling rocks, which receives the falling rocks is composed as follows. A hollow columnar body 20 includes net members 25 vertically and laterally combining linear elements formed in a spiral shape, wherein the outer diameter of the spiral is approximately doubles the diameter of the linear element, and is capable of self-holding the shape. A plurality of the hollow columnar bodies 20 without arranging the linear elements in the vertical direction are arranged so that mutual side ends 26 are superposed in the direction of extension at the net part configuring the side end of the hollow columnar body 20. Furthermore, the hollow columnar bodies 20 are connected to each other by adding spiral linear elements 55 for connection to the net members 25 of the side ends 26. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To enable a long spiral wire rod to be successively guided and cut in a device for guiding/cutting a spiral wire rod, and to provide a method therefor. SOLUTION: The device is composed as follows. At least a first guide part 21, whose diameter is reduced on the side of manufacturing counter-spiral, is supported freely rotatably so that the spiral wire rod coming out from a spiral wire rod manufacturing part A is revolved in a state of the jumping rope. The first guide part 21 is rotated at a speed equal to or almost equal to the rotational speed at the spiral wire rod manufacturing part. The spiral wire rod, which comes out from the spiral wire rod manufacturing part A and to which centrifugal force generated by the revolving is imparted, is introduced to the first guide part 21. The spiral wire rod coming out from the first guide part 21 is cut with a cutting part 30. A second guide part 22 composed of a cylindrical body may be fixed to the tip of the first guide part. A third guide part 23 having a tapered conical inner face may be fixed to the tip of the second guide part 22. COPYRIGHT: (C)2005,JPO&NCIPI

Die parts, in which each pass line PL1, PL2 of the pre-stage and the post-stage has an angle each other, is used. The wire rod is fed in the pass line direction through from the pre-stage die part 20 to the post-stage die part 30 while rotating the post-stage die part 30 in the face vertical to the pre-stage pass line PL1. The pre-stage die part 20 has a plurality of pre-stage roller dies 24 capable of fixedly and freely rotating. The post-stage die part 30 has a housing 31, which is mounted freely rotatably to the pre-stage die part 20, and a hole die 33d which is mounted to the housing 31 and guides the wire rod. At least any one of the values among a wire rod feeding speed, a rotational speed of the post-stage die part 30, and the pass line angle is adjusted. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a method for manufacturing a spiral wire of an arbitrary pitch in the longitudinal direction of the wire and an arbitrary spiral radius in a plane orthogonal thereto, and a device of high efficiency and high controllability for effectively performing the manufacturing method. SOLUTION: The wire is pushed in by giving an extrusion force in the pass line direction to a roller die having at least two working non-drive or drive rolls. The spiral wire of an arbitrary pitch and an arbitrary spiral radius is obtained by freely controlling the distribution in the pass line direction of the offset quantity in x-axis and y-axis of the wire by adjusting the extrusion speed of the wire and the speed periodically changing in the two-dimensional direction (x-axis direction and y-axis direction) of the relative position between the wire and the die in the plane orthogonal to the pass line.
