An apparatus for connecting at least two rods by a wire clamp comprises, mounted on one housing portion, a movable handle portion for the advance of said wire clamp, and closing jaws which are adapted to bring the locking portions of the wire clamp into engagement beneath the rods to be connected, and in the other housing portion, a binding hook fitted on a knurled rod, in order to twist the closed loop of the wire clamp which is situated above the rods to be connected. A sliding plate, which is connected to the handle, comprises a mechanism directed to actuating a bending pin on one of the closing jaws, in order to provide for positive interlocking of the wire clamp, and a mechanism for controlling and achieving safe individualization and advance of the wire clamps. Such an apparatus is adapted for reliable, swift and relatively comfortable operation even when exposed to the rough handling on a construction site.

Apparatus for connecting at least two rods

In a method for connecting at least two rods, wherein a binding apparatus, which is provided with a rotatable hook member, seizes a wire loop, which extends around the rods, and twists the loop during a pulling movement. The wire clamp or clip which has leg portion ends provided with locking means is brought around the rods to be connected in such a manner that, when viewed from the hook member the locking means are brought into engagement with each other behind the rods, and the closed wire clamp in front of the rods is seized by the hook member of the binding apparatus and twisted. The device is required for this purpose includes a binding apparatus which has a slide member connected to a displaceable gripping member for the forward advancement of the wire clamp and closing jaws which are adapted to bring the locking members on the wire clamp into engagement behind the rods to be connected. In this method and with this device, it is possible to achieve a connection between two reinforcement steel roeds in one working operation, by a forward-pushing movement and a backward-pulling movement, so as to eliminate the complicated process of inserting the binding wire behind the rods to be connected. This method in particular, considerably facilitates the work on the ground. The method also permits less specialized personnel to be used and, in addition, is quicker than conventional methods.

Method and device for connecting at least two rods

A twistable wire clamp for connecting objects has a V-shaped configuration, the lower portion of each of its two shanks forming an oblong loop having locking means consisting of the closed end of the narrower loop, on one hand, and of a locking member projecting towards the inside of the wider loop and extending in the same plane as the loop, on the other hand. On each side of the transitional portion between said two shanks, said clamp is provided with a respective shoulder. Said clamp is placed, by means of an apparatus, around the objects to be connected or the opening to be closed, after which said locking means are brought into engagement with one another by said apparatus, and said wire clamp is seized in the area of said transitional portion and twisted by a binding hook of the apparatus. Said loops are convex with respect to their plane, and said closed end portion has a thinning and is bent over towards said other loop. Such a wire clamp provides reliable operation of the apparatus when effecting connections.
