The invention relates to the manufacture of prestressed concrete products, collected from a single block.Known internal anchor for the manufacture of prestressed concrete products, including the housing, the front portion of which is rounded, the back and bottom part is made flat, the sides of the housing and has a rounded groove, and the lower part of the housing is equipped with a Jack having in cross section the shape of a truncated wedge, and in longitudinal section the shape of a parallelogram.The aim of the invention is ogeda fact, that front part of the body of the anchor is equipped with editions of coaxially spaced holes and grooves in the rear part of the body is rounded, and the base chassis in the rear are also done with the issue. In this case base provided with side tabs to secure the beginning and end of the threads of the valve, and one of the projections made split.In Fig. 1 shows an anchor with three front releases and a cylindrical hole in them, end view; Fig. 2 is a side view; Fig. 3, a top view in Fig. 1.Anchor for reinforcing element consists of a body 1 with the releases in which there are openings 3, through which with the help of other parts carry the connection of one concrete product with another in the longitudinal direction. The housing 1 is made integral number of 2 editions of the anchor may be two, three, four, and so on, and the holes 3 in 2 editions can have a round, oval-longitudinal wedge-shaped and different form.Side surfaces of the housing 1 anchor and rounded front 4 provided with grooves 5 and the base 6 of the housing 1 of the anchor has a slot 7, through which the fastening bolt on the clamp pallet form, the slot 7 in the section about the existence of anchor for the inner creates the opportunity to change the nature of reinforcement in concrete, where the strength of concrete depends not on mortar concrete with metal fittings, and on the strength of the reinforcement, and therefore there is no need to create a preset parallel arrangement of reinforcement and anchor, to make them collapsible, bulky. This creates an opportunity to simplify the design of the anchor and many times to make it smaller, lightweight, placing anchors in two rows along the height of the product. The implementation of the housing 1 bolt with the socket 7 in the base 6 creates the opportunity to fix it on the pallet forms and apply native method navipane rebar anchor. The changing nature of work of reinforcement in concrete creates an opportunity to more fully utilize the properties of reinforcing steel and to apply reinforcing steel with high technical qualities, i.e. normative resistance, reducing this number of threads of the valve, reducing the consumption of steel in two or more times, taking into account and the weight of the anchors while freeing up production entirely from waste, and at the same time positioning the reinforcing elements in two rows along the height of the product. Performing small anchor design creates the opportunity to save it releases the required size with one hole in each issue, where PE is to be round, oval, longitudinal wedge-shaped and the other. The presence of nests in anchor for fixing it on the pallet forms and creating opportunities in the application of machine mode of navipane fittings, changes the role and nature of the issues at anchor, using editions of the anchor only for the connection of one product with another and with other parts in the longitudinal direction. 1. Anchor for reinforcing element, comprising a housing with grooves on its surface and with a wedge-shaped nest from its inception, having in longitudinal section the shape of a parallelogram, characterized in that, to allow connection of concrete products in a forward direction, the front part of the body of the anchor is equipped with editions of coaxially spaced holes and grooves in the rear part of the body is rounded, and the base chassis in the rear are also done with the issue.2. Anchor under item 1, characterized in that the base body provided with side lugs for fastening the beginning or end of the threads of the valve, and one of the projections made split.

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.

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: 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.

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.

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.

SUBSTANCE: mechanism is intended for attaching extended elements to each other, and especially such elements as reinforced bars and electric cables by means of at least one wire. Mechanism consists of two jaws (6, 7) moved down on the elements to be connected (8). There are provisions made for means (20) of supplying wire (12) along guide surface (10) of the first jaw (6) to guide surface of (11) the second jaw (7), thus forming a wire loop which envelopes the above elements on three sides, and in this case ends of this loop can be twisted on the fourth side of elements (8). Twisting means consist of device (14) rotating relative to jaws (6, 7) and guiding the wire (12) at its supply to jaw and removal from jaw.
