FIELD: construction. ^ SUBSTANCE: dowel contains rod with longitudinal central opening and having remote and spacing zones. In rod spacing zone two longitudinal grooves are located that separate spacing zone into two halves. On external surface of rod spacing zone along its length in diametral planes annular grooves are arranged. On internal surface of rod spacing zone longitudinal blind grooves are provided. Annular grooves of one half of rod are displaced in relation to its second half, and mentioned halves are connected between each other with links. ^ EFFECT: increase of dowel bearing capacity in relation to axial and transverse operation loads, simplification of dowel installation. ^ 4 cl, 9 dwg |
