Reinforcement hook with clamp
SUBSTANCE: invention is attributed to construction engineering and can be used for binding of reinforcement cages of concrete products. Reinforcement hook contains shaft on one end of which handle is installed which can be rotated, and the second end of the shaft is tapered and bended as hook. Lever is hinged on the handle. The lever is capable to change position relative to handle. Two more levers are installed on shaft of reinforcement hook which levers can travel along hook and relative to each other and they are interconnected by elastic element. As a result due to simple fastening elements using, binding with wire pieces without loop is provided and production is cheapened.
EFFECT: cheapening of construction.
The invention relates to the field of construction and can be used for tying rebar reinforced concrete frames products.
There is a method of tying rebar pieces of wire with a slightly blunt cutters. The piece of wire is slid around the overlapping rods, tails crossed, grab the pliers and fold in the harness. However, quickly rotate the pliers, not releasing the wire tails quite difficult.
The described method of tying rebar wire twisting with rebar hook: folded in half and rolled to a turn and a half pass under the wire overlapping rebar, take it hook over the loop, bring the tail through the hook and turn the handle, fold in the harness .
Known rebar hook consists of a metal rod, one end is pointed, cone-shaped and bent a hook to catch the loop and the other end is bent, so that the auger, which can be rotated with one hand and arm, rotating on the last shoulder rotation. Rebar hook is taken as a prototype of the claimed invention.
The disadvantage of this hook is that it can be used only for mating fastening elements, with the end of the ear or loop. The task of the invention is the equipment and the known hook clip, which will allow a mating pieces of wire without loops.
The technical result of the invention is to reduce the cost of production through the use of simple fasteners. The technical result is ensured by the fact that the handle is attached to the lever with position change in relation to it, and on the shaft are two lever can move along and relative to each other and interconnected by the elastic element.
The invention is illustrated by drawings. In the drawings shown.
1, 2 - proposed reinforcing the hook.
3, 4, 5, and 6 3 and 4 levers.
Numbers denote: 1 - shaft 2 - arm, 3, 4 - arm, 5, 6 - spring 7 - washer 8 - lever arm, 9, 10 - wire tail.
We offer rebar hook consists of a shaft 1, one end is pointed and bent in the form of a hook, and the second set arm 2, the rotating relative to the shaft, 1, 2. Shaft mounted two levers 3, 4 can move along the shaft and relative to each other. The levers 3, 4 are attached to the elastic member such as the spring 5 and the shaft 1 and the lever 4 - spring 6. On the shaft between the handle 2 and the lever 4 is installed washer 7 to rotate and move along the shaft. On the handle pivoted lever 8 can be moved relative to the handle.
The device runs the trail the way. The lever 8 is pressed against the arm 2, and the lever pushes the washer 7, which in turn pushes the lever 4. The lever 3 moves together with the lever 4 and its end jams first wire tail 9. Then the lever 8 is pressed stronger, the lever 4 is shifted and his butt jams of the second wire tail 10. The shaft 1 turn several times and thus weave two wire tail in tow. Then the lever 8 is released and the springs 5, 6 return the device to its original position.

Rebar hook containing the shaft, one end of which is mounted for rotation arm, and the second end of the shaft is pointed and bent in the form of a hook, characterized in that it is provided with a lever pivoted on the handle with the ability to change the position in relation to it, and the two levers mounted on the shaft for movement along and relative to each other and interconnected by the elastic element.
SUBSTANCE: armature guy is carried out at first in angular cells on construction contour, then in central cell, after in cells adjoining to central cell on all central axis across construction, then on cells of layer adjoining to central layer of cells in direction to external contour and at the end cells located on construction perimeter. In angular cells an armature guy is made in spans between a corner pillar and the first from it in two axes on construction location. In cells adjoining to central cell, on all central axis a guy is made on longitudinal spans on construction location, on cells of a layer adjoining to central layer of cells, guy is made in two mutually perpendicular spans, beginning from central axes concerning central cell, thus guy on different parts is carried out by different devices.
EFFECT: increase of load-carrying capacity of construction floorings and reliability of devices for armature guy.

FIELD: equipment designed for fastening reinforcement by means of wire, for example for fastening mutually crossing reinforcing rods, possibly in building.
SUBSTANCE: machine includes housing; rotating drum carrying wire for fastening reinforcing rods; unit for controlling drum rotation; one or more detected objects. Detected object may be placed on lateral surface of drum. At controlling rotation of drum, said object is detected through opening of lid providing light reflection from light irradiator. Light reflected from detected object and light reflected from lid is received for determining difference between their intensity values.
EFFECT: enhanced operational reliability of machine, elimination of errors at monitoring wire consumption.

FIELD: preparing, conveying, or working-up building materials or building elements in situ, mounting and prestressing of reinforcing inserts.
SUBSTANCE: reinforcing bar binder feeds wire while rotating a wire reel installed in chamber and binds reinforcing bars. The chamber comprises the first detecting means to detect wire reel rotation and the second detecting means to detect number of second wire reel parts to be detected during reel rotation by the first detecting means. Binder body is provided with control means to control the amount of fed wire or wire torque depending on the number of second parts detected by the second detecting means.
EFFECT: increased structural simplicity and provision of automatic regulation of fed wire amount and torque thereof.

FIELD: apparatuses for fastening reinforcing parts, for example mutually crossed reinforcing rods.
SUBSTANCE: drum around which wire for fastening reinforcing rods is wound is mounted in shaft arranged in housing. Annular recess is formed along edge of opening of housing. Diameter of said recess exceeds that of lower part of housing. At side of opening of housing drum has flange arranged in said annular recess. On inner peripheral surface of opening of drum boss there is dent for preventing drum separation from its mounting shaft. On outer edge surface of shaft there is mounting recess for engaging dent.
EFFECT: improved design preventing wire penetration into gap between housing and drum, enhanced operational reliability of drum and machine for binding reinforcing rods.
