Purpose of the development: Purpose: Due to the transition of the construction industry on the reinforcement of concrete structural elements in thermal hardening of the reinforcement FMI has developed a special method of connecting reinforcement bars crimp sleeve.

Recommended application field: Fields of application: capital construction, reconstruction work.

Technical characteristic: Main technical characteristics: 1. Connect rebars produced ferrule fittings for classes A500S, A600S, A800S diameter 12 ... 14 mm. 2. The geometrical dimensions of the coupling sleeve:    The diameter of connection    reinforcing bars, mm D, mm, d, mm L, mm    12 19.5 100 13.2    14 26.0 100 15.6

Advantages over analogues: Advantages:        - For the method of connecting rods developed specifications, guidelines and portable           implementation of the proposed method on a construction site;        - In comparison with the welding method of the compound thus more economical. On request it is possible to quickly produce equipment for connecting reinforcing bars of different diameters.

The development stage readiness: Introduced in production

Technical and economic effect: Permanent connection of the thermal hardening way valve is being promoted in the "Ukravtodor", where he proved to be a reliable and easy to use.

Description of the development:
()
Conducted numerous studies on the static and fatigue strength of the joints and reinforced concrete beam specimens reinforced rods connected showed that their carrying capacity is equivalent to the continuous rod.
