METHOD OF INSTALLING ARMATURE RODS Russian patent published in 2018 - IPC E04C5/16 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, namely to a method for joining reinforcement of reinforced concrete products. Method of installation is carried out with the help of a coupling, in which the stackable and increasing reinforcing bars inserted into it from the opposite sides are pre-positioned, the joined ends of which abut against each other in the middle part and compress its input portions constituting at least three diameters of the reinforcement bars to form a zone not subjected to compression, and transitional sections, on the section located between the middle and input parts, which provides a variable value of deformation of the clutch metal. Mounting the valve without crimping the middle part of the coupling allows the build-up (joining) of reinforcing bars without end-cutting in the conditions of a construction site.

EFFECT: formation of the transition curve of the surface from the crimped to the middle part allows to ensure equal strength of the completed connection, to increase its reliability, to increase productivity and quality of work.
