FIELD: process engineering.SUBSTANCE: invention relates to joints of reinforcement rods an may be used in construction and erection and making construction components from cast-in-situ and prefabricated concrete. Proposed joint comprises reinforcement rods, strap and lengthwise joint weld seams. Reinforcement rods are arranged in said strap with clearance there between. Cylindrical strap has definite-width-and-thickness cutouts. Weld seam are made between strap and rods. Said strap features tubular cross-section with definite ID.EFFECT: increased strength and reliability, minimum softening nearby seams.5 cl, 12 dwg, 1 ex |
