An improved reinforced structural member and method of fabricating the member. The structural member is a truss slab of a type embodying a lower concrete slab having reinforcement embedded therein; means providing a network of passages overlying the base slab; and an overlying concrete slab with reinforcement therein, including concrete columns extending between the overlying slab and the base slab. Additional reinforcing members of struts are provided connected between the reinforcing members in the lower slab and the reinforcing members in the upper slab. These members are of improved construction embodying a lower section and a separable upper section. The lower section extends to the height of the top surface of the lower slab permitting improvements in the method in that the lower slab can be poured without the reinforcing struts or members being in the way. The upper section of the reinforcing strut is then joined to the lower section, after which the upper slab is poured.

An improved method of construction of a composite truss member of a type which includes a base slab of concrete containing reinforcing means extending through the slab, the said truss member having a web formation providing a network of spaces for allowing air circulation through the network, the truss member having an overlying layer of concrete over the web formation and having spaced columns of concrete extending through the web formation to the said base slab, the said truss member having reinforcing members embedded in the slabs including reinforcing strut members extending through the spaced columns of concrete, the improvement including the step of positioning first reinforcing strut members on a surface on centers corresponding to the centers of the spaced columns of concrete to be formed, forming the said reinforcing members to have top ends when positioned to be at substantially the top level of the lower slab of concrete and then pouring the concrete with the said reinforcing members in position prior to forming the said network and overlying layer of concrete and spaced columns of concrete, and securing second reinforcing strut members to predetermined ones of the first reinforcing strut members, attaching screed support means to said predetermined second reinforcing strut members, supporting screeding means from said screed support means, and screeding the surface of the lower slab of concrete.
