Building or construction members are provided which include wooden girders or beams which form a framework onto which is molded a concrete plate or slab. A connection is formed between the beams and the concrete slab at least one sheet metal strip (4) having on one edge clips in the form of indentations (5) provided with teeth (6) and on the other edge with bent portions (9) constituting a flanged edge. On the flank of the sheet there are stamped portions (7) forming projections and cut portions (8) forming openings issuing onto the edge on which is formed the flanged edge (9). The indentations (5) provided with the teeth (6) are anchored in the beam (1), while the openings are permitting the passage and retaining of metal fittings (3). The flanged edges (9), the stamped portions (7) and the enlargements (8) participate in the anchoring of the metal sheet (4) in the concrete slab (2).
Composite wood-concrete construction member comprising a concrete slab (2), beams or girders (1) made from wood, in solid, glued laminated, agglomerated fibre or particle form and constituting framework on which is moulded said concrete slab (2), metal fittings (3) embedded in said concrete slab, and sheet metal strips, at least one of said sheet metal strips (4) fixed to each of said beams, said sheet metal strips having clips (5-6) on one edge and inserted in the beams (1), said sheet metal strips also having joining means for joining the sheet metal strip (4) to at least one of the concrete slab (2) and the metal fittings (3).
