Metal support for wood structural elements

Claim 2

In a wooden truss structure or the like for supporting structural elements the improvement which comprises: a. a plurality of spaced wooden truss elements; b. a narrow transversely extending channel in each said truss element, said channels being aligned in a manner to receive a straight metal strip inserted therein; c. a metal support strip comprising a portion generally U-shaped in cross section, said U-shaped portion being positioned snugly in said channels; and d. nail means extending downwardly inside said U-shaped portion, through the bottom of said U-shaped portion and into the wood defining each said channel in a manner to fasten said strip in each said channel and to effect the spreading of the sides of said U-shaped portion tightly against the sides of said channel.

Claim 3

The structure according to claim 1 and additionally comprising a flange extending outwardly approximately perpendicularly from the top of said U-portion, said flange lying against the surface of said truss.

Claim 4

The structure according to claim 2 wherein said strip comprises two such flanges to form a strip which is generally T-shaped in cross section.

Claim 5

The structure according to claim 2 comprising two such channels and wherein said strip comprises two such portions joined by said flange, each said channel snugly containing one of said portions.

Claim 6

The structure according to claim 3 comprising two such channels and wherein said strip comprises two said T-shaped sections having a common flange, each said channel snugly containing one of said portions.

Claim 7

The structure according to claim 3 wherein a plurality of such truss elements and a plurality of such strips form a grid and wherein there are in each of said truss elements a plurality of said channels and there are a corresponding plurality of said strips, said truss elements being substantially parallel to each other and said strips being substantially parallel to each other and perpendicular to said truss elements.

Claim 8

A floor comprising: a. a plurality of spaced parallel trusses or the like; b. a plurality of spaced parallel narrow channels extending transversely across the surface of each of said trusses; c. a plurality of spaced parallel metal support strips positioned perpendicular to said trusses to form a grid therewith, each said strip being a unitary element generally T-shaped in cross section and having a generally U-shaped base leg portion and upper flange portions; said U-shaped portion positioned snugly in aligned channels in said parallel trusses and said flange portions lying against truss surfaces; d. nail means extending downwardly inside said U-shaped portion, through the bottom of said U-shaped portion and into the wood defining each said channel in a manner to fasten said strip in each said channel and to effect the spreading of the sides of said U-shaped portions against the respective sides of said channels; e. plywood panels secured to said trusses and resting on said flange portions.

Claim 9

A floor comprising: a. a plurality of spaced parallel trusses or the like; b. a plurality of spaced parallel narrow channels extending transversely across the surface of each of said trusses; c. a plurality of spaced parallel metal support strips positioned perpendicular to said trusses to form a grid therewith, each said strip being a unitary element generally T-shaped in cross section and having a generally U-shaped base leg portion and upper flange portions; said U-shaped portion positioned snugly in aligned channels in said parallel trusses and said flange portions lying against truss surfaces; d. nail means extending downwardly inside said U-shaped portion, through the bottom of said U-shaped portion and into the wood defining each said channel in a manner to fasten said strip in each said channel and to effect the spreading of the sides of said U-shaped portions against the respective sides of said channels; e. plywood panels secured to said trusses and resting on said flange portions.

Claim 10

A wall comprising: a. a plurality of spaced parallel trusses or the like; b. a plurality of aligned narrow channels, each extending transversely across the surface of one of said trusses; c. a metal support strip spanning said trusses, each said strip being a unitary element generally T-shaped in cross section and comprising a generally U-shaped base leg portion, said U-shaped portion positioned snugly in said aligned channels; and d. nail means extending downwardly inside said U-shaped portion, through the bottom of said U-shaped portion and into the wood defining each said channel in a manner to fasten said strip in each said channel and to effect the spreading of the sides of said U-shaped portions against the respective sides of said channels.

Claim 11

A wall comprising: a. a plurality of spaced parallel trusses or the like; b. a plurality of aligned narrow channels, each extending transversely across the surface of one of said trusses; c. a metal support strip spanning said trusses, each said strip being a unitary element generally T-shaped in cross section and comprising a generally U-shaped base leg portion, said U-shaped portion positioned snugly in said aligned channels; and d. nail means extending downwardly inside said U-shaped portion, through the bottom of said U-shaped portion and into the wood defining each said channel in a manner to fasten said strip in each said channel and to effect the spreading of the sides of said U-shaped portions against the respective sides of said channels.

Claim 12

The wall according to claim 8 and comprising stringers joining ends of said trusses and wherein each of said stringers is provided with one such aligned channel snugly containing said portion of said strip.
