<p>Bearing structure of concrete bridge prestressed by cohesive and / or free cable, comprising in cross section of at least single-chamber back girder (1) and the subsequent outer brackets (4), whereby from side plates (13) of back girder (1) outwardly stand out at its lower plate (12) supporting teeth (14) and at the upper plate (12) center consoles (111), on which continue monolithic plates (41) of outer bracket (4) arranged along the sides of the central brackets (111) and on their level , whereby the outer brackets further include prefabricated braces (2) arranged between the supporting claws (14) and outer ends of monolithic plates (41). Prefabricated brace (2) comprises in the direction from supporting claw a planar upward inclined part (21) consisting of a plate and the planar horizontal part (211). In the transition area upward inclined part (21) to a horizontal part (211) is a prefabricated brace (2) connected to the outer edge of a monolithic plate (41) and the horizontal part (211) of prefabricated brace (2) follows the monolithic plate (41) of outer brackets (4) and forms a marginal part of the bridge deck.</p> |
