A composite structure, wood - concrete destiny in particular to the embodiments of roadways of permanent works

摘要

The composite structure comprises longitudinal wooden beams 1, a slab of concrete carried by the beams and the slab. Each connector 12 is in the form of a double bracket reversed, the upper flange 13 is embedded in the concrete, and the lower flange 20 is sealed in a slot 21 of the beam 1. The intermediate horizontal part 15 of the connector 12 is fixed to the upper flange of the beam 1 by the rods 17 passing through the openings 16 of the intermediate part 15 and sealed in the holes 18 of the beam. & br / the invention permits the production of frames of bridges using only very little steels.
