A panel system for the containment of landslides caused by partial collapses and also by “rock breakdowns”, for use in the fortification of mining tunnels, hillsides and roads, together with anchor bolts and plates, comprising a network constituted by straps of metal or other material resistant to traction or with the capacity of tearing along the strap (1) (2) (3), with each node of this network firmly linked with a buckle (6) (7) (8) (16) and with a frame (20) attached to this network, where the frame comprises flat tendons (17) near the perimeter of the panel, linked to plates with lugs (D11) or with flat connectors (12) (13) (14) (15) which go beneath the normal plates.

A threaded reinforcing bar coupling structure comprises a pair of reinforcing bars and a tubular coupler connecting the pair of reinforcing bars. Each of the reinforcing bars is a deformed reinforcing bar having spiral node portions on an outer periphery of a reinforcing bar main body having a round shaft shape. A cylindrical portion with node portions removed is formed on an end portion of the reinforcing bar, and a male threaded portion is formed on the cylindrical portion. The male threaded portion has hardness or tensile strength greater than that of a remaining portion of the reinforcing bar. The pair of reinforcing bars is connected by the screw tubular coupler that is screwed onto the male threaded portions.

A reinforcing bar binding machine (1A) includes a magazine (2A) in which a wire (W) is housed, a curl guide unit (5A) that winds the wire (W) around a reinforcing bar (S), a wire feeding unit (3A) that feeds the wire (W), and a binding unit (7A) that twists crossing portions between one end and the other end of the wire (W) wound around the reinforcing bar (S). The wire feeding unit (3A) is configured such that a second displacement member (36) for displacing a second feed gear (30R) is located behind a second feed gear (30L) and provided between the second feed gear (30L) and a handle portion (11A).

The disclosure relates to a crimping station comprising a crimping tool designed to crimp a sleeve around a first end portion of a thread and around a second end portion of a thread, said crimping station comprising a sleeve preparation subassembly which has a feed device that supplies a metal strip and conveys said strip as far as a shaping device designed to plastically deform said strip in order to give said strip a concave curved cross section, so as to obtain a preformed strip, and then as far as a cutting device which is designed to sever a portion of length of said preformed strip in order to obtain a sleeve preform that a loading tool places within the crimping tool.

A device and method for making a wire basket, the device having a spinning fixture with a top plate with an outer periphery, arms attached at a top end at the periphery of the top plate and projecting downwardly, such that bottom ends of the arms collectively form a circular arrangement having a diameter greater than the diameter of the top plate, a means for guiding wire onto the spinning fixture such that the wire is wound onto the spinning fixture in a preselected pattern, and contacts to maintain the wire onto the spinning fixture in preselected locations, and the method including providing an apparatus for delivery of wire through a wire feed and for translating the wire feed lineally along a traverse, providing a spinning fixture for winding wire thereon, and winding a preselected pattern of wire onto the spinning fixture by translating the wire feed along the transverse.

A binding machine includes a body part, a feeding unit configured to feed a wire, a first guide extending in a first direction from an end portion on one side of the body part, configured to guide the wire fed by the feeding unit, and having a first induction part provided on a tip end-side in the first direction, a second guide spaced from the first guide with an interval, in which a binding object is inserted, in a second direction orthogonal to the first direction, and configured to guide the wire fed by the feeding unit, and a twisting unit configured to twist the wire. The first induction part is constituted by a surface inclined in a direction in which the interval between the first guide and the second guide decreases from a tip end-side toward a base end-side of the first induction part in the first direction.

An apparatus for twist tying wire around intersecting rebar bars. The apparatus is configured to receive and discharge precut wire segments, form and wrap the wire around the rebar, and twist the wire securely around the rebar. The user merely positions the tool at the rebar intersection, release a wire segment into the work end of the tool, and with a single fluid motion move a slide mechanism up to bend the wire segment around the rebar and twist it about itself to tie the rebar together.
