Abstract
A "top-down" construction technique is described. The deck form assemblies for each structural concrete slab are lowered and supported from the level above the same. In the preferred arrangement the form deck assemblies for each structural slab are supported by the concrete slab itself above the proposed location of the new structural slab.
Claims13
In a method of constructing a multi-level building structure, the steps comprising:
- (a) providing for at least a portion of said building, a generally vertical frame structural column network made up of spaced, generally vertical columns that are substantially free of one another;
- (b) forming for a horizontal diaphragm slab which is to structurally connect vertical columns together, a first concrete structure with a form assembly held at a first location at the level to be defined by said horizontal diaphragm slab;
- lowering said form assembly from its first location to a second location at a lower level for another horizontal structural diaphragm slab;
- and
- (c) using said form assembly at said second location to form a concrete structure for the horizontal structural diaphragm slab at said lower level.

In a method of constructing a multi-level building structure, the steps comprising:
- (a) providing for at least a portion of said building, a generally vertical frame structural column network made up of spaced, generally vertical columns that are substantially free of one another;
- (b) providing temporary bracing between at least some of said columns;
- (c) thereafter forming with a deck form assembly, a first generally planar concrete structure for a horizontal diaphragm slab which is to structurally connect together said vertical columns and span the space between adjacent spaced columns of said network;
- (d) thereafter lowering said deck form assembly from its first location for said horizontal diaphragm slab to a second location at a lower level for the formation of the next preceding lower horizontal structural diaphragm slab;
- (e) supporting said form assembly at said second location from the level defined by the slab of step (c);
- (f) thereafter using said form assembly at said second location to form a generally planar concrete structure also spanning said space between adjacent columns;
- and
- (g) repeating the steps labeled (c)-(f) to form a plurality of succeeding horizontal diaphragm slabs for said multi-level building structure.
