COMPLEX DEVICE FOR CONNECTION OF REINFORCING BARS AT CONSTRUCTION SITE Russian patent published in 2025 - IPC E04C5/16 B23K31/02 

FIELD: construction.

SUBSTANCE: invention relates to equipment for construction and installation works. For convenience of process of execution of construction and installation works on fabrication of reinforcement joint by pouring of molten metal the device has small dimensions, has mobility. Proposed device comprises working chamber with metal melting crucible and cooling system to maintain preset temperature conditions. Working chamber is made with a side and a steel bracket and is located in one of the sections of the two-section box made with heat-insulating walls. Melting pot is equipped with special gripping elements for its movement, as well as a drain ceramic tube for joint filling. In the other section of the housing there is a cooling system in the form of a tank with nitrogen, a pump for its transfer, connecting pipes and a spiral cooler.

EFFECT: higher rate of reinforcement jointing at construction site and higher quality of jointing.
