Description

The invention relates to reinforcement, "nymi elements used for the manufacture of prestressed concrete structures.

A reinforcing element is known that contains a bundle of continuous winding wires with an anchor fixed on loop ends and a grip for tension in the form of a gage connected to a sleeve on which a nut is installed, while grommets of elastic material with bent edges £ 1 are installed between the concentric layers of the wire ].

However, this reinforcing element has a complex structure and laborious manufacturing.

The closest to the invention is a reinforcing element containing a bundle of continuous winding wires with a tension grip attached to loop ends and a lingering anchor consisting of an insert and a tip covering the end portion of the loop [2].

A disadvantage of the known reinforcing element are high intensity and large dimensions of the drawbar anchor.

2

The purpose of the invention is to reduce the metal and dimensions of the drawbar anchor.

5 The goal is achieved by the fact that in the reinforcement element containing the beam

. continuous winding wires with a tension grip and a lug anchor fixed on loopback ends, consisting of an insert and a tip covering the end part, a loop current, the insert is made in the form of a metal plate equipped with fixing clamps with paper clips, and the tip is in the form of a crimp

'5 clip, provided with a covering metal strip, while the latter is missed inside the clip fixing clamps liner,

__ In order to preserve the rows of wires at the loop end of the beam after removing the drawbar anchor, the end portion of the loop is provided with a tie.

FIG. 1 shows the reinforcement element, a general view; in fig. 2 - pet25 left end with drawl anchor; in fig. 3 shows section A-A in FIG. one; in fig. 4 - looped end after removing the drawbar anchor; in fig. 5 tip before installation; on

The reinforcing element contains a bundle of 1 continuous winding wires with a claw 3 fixed at the loopback end 2 for tension and an extended Anchor on the end section of loop 4, as well as a hinge branch connection unit 5.

The draw anchor consists of an insert that is made in the form of a rigid steel plate 6 connected by welding with two fixing clamps 7 with staples 8, and also from a tip in the form of a compression clamp 9 rigidly connected to a female steel strip 10 which is connected to a compression clamp 9 in the place of maximum opening of the loop. The rigid plate b is installed on the inner side of the end portion of the loop.4, and the circumferential strip 10 is outside the loopback end and is missed inside the clips 8 of the fixing clamps 7.

In order to maintain wire strangeness, after removing the pull-in anchor, a stitch 11 is installed at the end section of loop 4. Twisting 12 is installed at the entry point of loop 4 into the construction channel on the node 5 of the connection of the hinge branches. the clip 13 and is pressed for greater stabilization of its position to the end of the loop 4 with a rigid plate 6 and the surrounding strip 10.

The device works as follows.

When winding the wire on the stops for receiving the beam 1 on one of the stops are pre-fixed with a rigid plate 6 with retaining clamps 7, assembled as shown in FIG. 6, as well as the coupler 11. After navivika beam, the ends of the fixing clamps 7 and the ends of the coupler 11 are connected, respectively, with clips 8 and 13, passing inside the clips 8 fixing clamps 7 and outside the coupler 11 with a clip 13 covering the strip 10. After this, close the crimping clamp 9, connected to the female strip 10 prior to installation as shown in FIG. 5, around the loopback end 4 at the point of maximum opening of the loop. At the same time establish twist 12 on

node 5 connection of the loop branches for fixing the length of the loop. After that, the reinforcing element is removed from the stop, fixed to the loopback end 4 at the site of placement of the rigid plate b a broaching rope (not shown), pulling the reinforcing element through the structure channel. After insertion of the loopback end 4 into the construction channel ’, twist 12 is removed.

After pulling the reinforcing element through the construction channel, disconnect the drawstring rope, remove the rigid plate 6 with the fixing clamps 7 with the pre-folding of the staples 8. Next remove the crimping clamp 9 together with the female stripe 10.

On the end section of the loop 4 remains a coupler 11 to maintain the rows during anchoring. Next, proceed to the anchoring of the reinforcing element using a stationary anchor.

Claims (2)

Claim . 1. A reinforcing element containing a bundle of continuous wire wires with a gripper attached to loopback ends and a lingering anchor consisting of an insert and tip covering the loop end portion, characterized in that, in order to reduce the metal capacity and dimensions of the pull-in anchor, the liner is made in the form of a metal plate, provided with locking clamps with clips, and the tip - in the form of a crimping clamp, provided with a covering metal strip, while the latter is missed inside the clips of the locking clamps of the liner. 2. The element in π. 1, characterized in that, in order to preserve the rows of wires at the loop end of the beam after removing the drawbar anchor, the end portion of the loop is provided with a tie.
