Abstract
Abstract Floor and ceiling supports, both generally V-shaped, are connected by a central post-like intervening spacer structure portion, the open arms of the V bearing against the ceiling, to be poured, and the floor or support, which may be a previously poured cement construction, respectively; the V-shaped support portions are preferably made of welded pipes, connected with the central spacer portion by holes and cross pins fitting into the holes to adjustably space the floor and ceiling portions, and permit limited swinging movement to allow for slight misalignments. The erected support structure of the double-V form is laterally maintained in position by stiffening members, preferably clamped to the post-like spacer and providing laterally extending clamp connections for pipe length to hold the support structure in lateral alignment.

Claim 4
Dependent Claim
56 words
Structure according to claim 1, wherein the attachment means for at least one of the support portions (4) comprises holes (8) formed in the spacer portion extending transversely to the plane of the V-structure of the respective support portion, and pins (9) extending through both the floor support portion and the holes in the spacer portion.
Claim 5
Dependent Claim
46 words
Structure according to claim 1, wherein the attachment means for the floor support portion comprises a reception tube (7, 7'') telescopically and longitudinally adjustably secured to the spacer portion; and bearing pin means (4g) swingably connecting the inverted V-structure adjacent its apex to the reception tube.
Claim 6
Dependent Claim
54 words
