Description

The utility model relates to construction, namely to the reinforcement of building envelopes, energy-efficient buildings and structures.

The technical solution according to the patent of the Russian Federation No. 31802, E04C 5/07, publ. 08/27/2003, which describes a reinforcing element (flexible connection) with a rod formed of a polymer binder and oriented along the axis of the rod of threads from a durable low-modulus material. It contains anchor hooks at the ends in the form of conical thickenings, wherein anchor hooks are formed by a layer of sand fixed on the surface of the rod with a cured polymer binder. The disadvantage of this anchor element is the complexity of its manufacture, because the process of applying thickenings at its ends is an additional operation.

Also known is the reinforcing element for wall structures according to the patent of the Russian Federation No. 2142039, E04C 5/05, publ. 11/27/1999 (prototype) having conical hooks at the ends with sections of constant or decreasing section and a restrictive sleeve with a support flange mounted in its central part. The disadvantage of this design is its complexity and the need to include in the line for the manufacture of reinforcing elements special equipment for placement in a tube formed from strands of fiberglass, impregnated with a binder, embedded element. In addition, the surface of the obtained rod is smooth, which does not provide its necessary adhesion to mortar or concrete.

The technical result of the proposed solution is to simplify the manufacturing process of flexible communication and its reliable fixation in mortar or concrete.

The specified technical result is achieved in that in a flexible connection containing a composite rod with a restrictive sleeve located in its middle part, and anchors at its ends, the rod has a granular coating along its entire length. Moreover, the anchors can be made in the form of segments of a plastic pipe or in the form of segments of a metal pipe with adhesive applied to them and a granular layer.

The proposed technical solution is illustrated by drawings.

FIG. 1 - flexible connection - spacer.

FIG. 2 - flexible connection - suspension.

FIG. 3 - flexible connection - suspension with anchors in the form of pipes.

In FIG. 1 shows a flexible connection in a three-layer enclosing structure containing a rod 1, the cylindrical part of which has a granular coating 2, for example sand. In the middle part of the rod 1 there is a restriction sleeve 3, the flange of which is at right angles to the rod 1. The end parts of the rod are anchors 4. A flexible connection is possible when the restriction sleeve 3 has a flange located at an acute angle to the rod 1 (Fig. . 2). In the third embodiment, to the construction according to the second embodiment, thickeners (metal or plastic) are located on the anchors 4 of the rod in the form of pipe sections 4 pressed onto the anchors 4 of FIG. 3).

Flexible tie-spacer (Fig. 1) is used in a three-layer enclosing structure (concrete-insulation-concrete) for fixing the outer facade layer of the sandwich panel relative to the inner supporting layer. It is perpendicular to the concrete layers of the building envelope and perceives a horizontal compressive load. Flexible anchor depth is less than 50 mm according to GOST 31310-2005.

Compared to a flexible tie-strut, a flexible tie-suspension (Fig. 2) and a flexible tie-suspension with a pipe-shaped anchor (Fig. 3) are inclined with respect to the previously installed strut and absorb a vertical tensile load.

Flexible communication is made as follows. A granular coating (e.g. sand) is applied to the composite rod. Further, in the middle part of the rod, a restrictive sleeve with a flange is formed using a thermoplastic machine. On a flexible connection-spacer, the restrictive sleeve is formed at right angles to the rod (Fig. 1), and on a flexible connection-suspension - at an acute angle to it (Fig. 2, Fig. 3).

Flexible connection - a suspension with an anchor in the form of a pipe (FIG. 3) is made by pressing pipe sections (metal or plastic) in a known manner onto the flexible communication anchors of FIG. 2. In the case of using a metal pipe, it is necessary to further cover it with an adhesive, for example, epoxy adhesive, and then apply a granular layer to it.

Compared with the prototype rod, the manufacture of the proposed rod is more technologically advanced and less labor intensive. In addition, the use of special equipment is not required. The rod is anchored due to adhesion, and not due to thickening of the rod itself. The advantage of the proposed technical solution is its more durable connection of a flexible connection with a concrete layer. The most reliable connection is obtained using the structure of FIG. 3, because along with adhesive interaction, anchoring occurs due to the expanded part of the anchor in the form of a pipe segment.

Thus, the claimed technical result was achieved: a more technological process for manufacturing flexible communication and its more reliable fixation in mortar or concrete was created.
