FIELD: construction.SUBSTANCE: device for manufacturing the reinforced concrete sleepers with studs contains the form for laying concrete mixture, elements for installation and fixation of studs. Elements for mounting and fixing the studs are designed as a rod made of thermoplastic elastomer (TPE), at the front edge of lower part of the rod there is embedded metal screw by means of which the rod is connected with the form with the possibility of disassembly, the lower part of the rod is designed with thread the pitch of which coincides with the pitch of inner thread of stud; the front edge of lower part of the rod is designed as a washer.EFFECT: increase of reliability of spatial fixation of studs in the form, exclusion of concrete mixture ingress into the inner cavity of stud.5 cl, 2 dwg |
