The invention relates to the manufacture of reinforcement products for reinforced concrete structures and can be used to form joints of intersecting reinforcing bars.

The aim of the invention is to increase the reliability of the connection, as well as to ensure the possibility of forming a multi-positioned unit.

FIG. 1 shows a rod connection, general view; in fig. 2 is a view A of FIG. one; FIG. 3 - device for connecting by connecting wire, general view; on ig. 4 is a view B in FIG. 3; in fig. 5 - node I Ea of FIG. four; in fig. 6 - -double-position |: disconnecting unit composed of two Devices.

The reinforcement rods 1 and 2 at the intersection point are connected by wire 3, the middle 1H part 4 of which is curved with a girth, 2 and the ends 5 are fixed around |, and 1 with spiral turns with a different 4-way winding.

I A device for the formation of such a connection-} 1, reinforcement rods consists of an orbit 6 with an opening 7 for gripping the rod- {I 1 and fixed on the body of flexible 1x8 disks 8 connected to the gear ones (scales 9 and mounted on the support 10 of the body 6. Each gear wheel to 9 is engaged with two teeth 11, with which gear racks 12 are engaged.

I In the bending disks 8, pro-holes and 13 are formed, corresponding to openings 7 in the core (lyce 6, and grooves 14 that are diametrically located to the notch grooves for fixing the ends of the | 1 wire 3. On the sides of the disks 8 facing each other, under the groove 14 41 are additional bending elements 15, 1 for example, in the form of rollers or stops for bending the ends of the wire after they exit the grooves 14.

To form a multi-position junction block, the rails 12 and the body 6 are made with connecting elements 16 and 17 for fastening them to the power cross member 18 and the frame 19, between which the power cylinders 20 are mounted.

The connection of the reinforcing bars is as follows.

The device is installed at the intersection of the rods in such a way that the support sleeves 10 rest on the lower rod 1 and the upper rod 2 lies between the bending disks 8, B of the slot 13 lay the wire 3 and press the connecting element LB to move the rails 12, and the disks 8 through one or a pair of gear 11 and a gear wheel 9 rotate in opposite directions. The length of the wire 3 covers the upper rod 2 with a bend, and the ends of the wire, fixed in the grooves 1, are bent in opposite directions and wound on the lower rod 1 with spiral turns. When the wire is twisted, its ends are gradually pulled out of the grooves 14 and, after leaving the wire, are bent by the bending elements 15 to form subsequent turns of the helix.

When several intersections of reinforcing bars are connected, the devices are combined into blocks with crosshead 18 and frame 19 with power cylinders 20 using connecting elements 16 and 17.

Claims (2)

1. A device for connecting intersecting reinforcing rods with a connecting wire, comprising a housing with an opening for gripping the reinforcing rod and bending disks located on their sides for twisting the ends of the connecting wire, characterized in that it is equipped with toothed rails, by means of gears with bending disks, in which slots are formed, corresponding to the openings in the housing, and grooves diametrically arranged with respect to the slot, for fixing The ends of the wires are fixed, and additional bending elements are fixed on the sides of the disks facing each other for the final twisting of the ends of the wire. 2. The device according to claim 1, characterized in that, in order to provide the possibility of forming a multi-position connecting unit, it is provided with a frame with a power traverse, and the housing and the toothed racks are made with fastening elements. viewA 12 fu-g3 FI.2 17 ten Fy .6 FIG. five rs
