An assembly of adjustable shoring apparatus and a leg brace assembly, said shoring apparatus comprising:
- upper and lower pairs of spaced apart parallel chords having horizontally extending longitudinal axes, the chords in said lower pair being spaced beneath and vertically aligned with respective chords in said upper pair,
- a plurality of struts extending obliquely from said upper chord pair to said lower chord pair and between the chords in each pair in a continuous longitudinal series of strut pairs of like substantially V-shaped configuration having their apices at said lower chord pair, the center lines of successive strut pairs being uniformly spaced apart,
- the chords in said lower pair having pairs of aligned holes in respective chords and centered on said center lines of successive strut pairs,
- means connecting the upper and lower ends of said struts respectively to the chords of said upper and lower pairs in a truss-like structure adapted for supporting a load on the chords of said upper pair,
- a plurality of vertically extending elongated legs each having a vertical series of support pin holes which extend transversely therethrough, said legs having upper portions inserted between the chords in said lower pair and lower portions extending below said structure to provide support therefor, and said legs being vertically reciprocally movable relative to said structure for adjusting the combined height thereof,
- the strut pairs in said series each being adapted for inserting one of said legs between the struts of and at the apex of the strut pair, said legs being inserted between said struts in respective selected strut pairs and being insertable alternatively between the struts of other strut pairs and at other locations along the length of said structure for supporting the structure alternatively at said other locations, said support pin holes in said legs being adapted for registering successively with said pairs of chord holes adjacent to the inserted legs,
- and means for supporting said structure on said legs adjustably at varying elevations including means carried by the chords in said lower pair and defining support pin holes, said hole-defining means being adapted for disposing the pin holes thereof on opposite sides of each leg for registry with said pairs of chord holes thereat and with said support pin holes of the leg successively in any of said locations of the leg, and a support pin removably insertable through a selected one of said support pin holes in each leg and through the support pin holes of said hole-defining means and said chord holes in registry therewith for transferring the load forces from said hole-defining means to said legs;
- and said leg brace assembly comprising:
- an elongated leg brace member having a longitudinal series of pivot pin holes therein adjacent to one end thereof and a connecting pin hole therein adjacent to the opposite end thereof,
- pin mounting means inserted in a pair of said chord holes at a first strut pair which is adjacent to a second strut pair having a leg inserted between the struts thereof,
- a pivot pin on said pin mounting means and extending transversely with respect to said structure and inserted in a selected one of said pivot pin holes in said leg brace member for swinging movement of the leg brace member thereon, said connecting pin hole in said leg brace member being arranged for registering with a selected one of said support pin holes in the leg inserted at said first strut pair, and
- a connecting pin removably insertable through said connecting pin hole and said support pin hole registering therewith,
- whereby the disposition of said pivot pin between said lower chord pair and said leg brace member is variable for connecting the leg brace member to the latter leg at points spaced varying distances below the lower chord pair and spaced above the lower end of the latter leg, and the leg brace member may be disconnected from the leg and swung upwardly on said pivot pin to a position wherein the leg brace member is disposed completely above the bottom surfaces of the lower chord pair to permit movement of the shoring apparatus on said surfaces without interference from the leg brace member.
