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.
Claims22
In a method of constructing a plurality of generally horizontal structural concrete diaphragm slabs for a multi-level building structure, the steps comprising:
- (a) providing a generally vertical frame structural column network made up of spaced vertical columns that are substantially free of one another;
- (b) structurally connecting spaced vertical columns together by making out of concrete with a deck form assembly, a first horizontal structural diaphragm slab providing said connection;
- (c) thereafter lowering said deck form assembly from the level defined by said first slab when it is made, to a position for the formation of the next lower structural diaphragm slab connecting said spaced vertical columns together;
- and
- (d) supporting said form for the construction of said next lower diaphragm slab from the level defined by said first slab.
In a method of forming a plurality of generally horizontal structural concrete diaphragm slabs for a multi-level building structure, the steps comprising:
- (a) providing a generally vertical column frame network made up of spaced vertical columns that are substantially free of one another;
- (b) structurally connecting spaced vertical columns together by constructing out of concrete with multiple deck form assemblies, a first horizontal structural diaphragm slab providing said connection;
- and
- (c) thereafter supporting said deck form assemblies from the level defined by said first slab for the construction of the next lower structural diaphragm slab.
In a method of constructing a plurality of generally horizontal structural diaphragm concrete slabs for a multi-level building structure, the steps comprising:
- (a) providing for said building structure, a generally vertical structural column frame network made up of a plurality of spaced vertical columns that are substantially free of one another;
- (b) connecting spaced vertical columns together by constructing a first one of said structural diaphragm concrete slabs with multiple deck form assemblies;
- (c) thereafter lowering said deck form assemblies from said first slab after it has been constructed into position for the construction of the next lower structural diaphragm slab.
In a method of making a plurality of generally horizontal structural concrete diaphragm slabs for a multi-level building structure, the steps comprising:
- (a) providing for said building structure, a generally vertical structural column frame network made up of spaced vertical columns that are substantially free of one another;
- (b) structurally connecting spaced vertical columns together by constructing a structural concrete diaphragm slab with deck form assemblies;
- (c) thereafter lowering said deck form assemblies from the first slab after it is constructed, to a position for the formation of the next lower structural diaphragm slab;
- (d) supporting said deck form assemblies for the formation of said next lower slab from said first slab, including supporting an attachment with said first diaphragm slab when it is constructed to transmit to said first slab, the loads expected during the formation of said next lower structural diaphragm slab;
- (e) said step of lowering including rotating a threaded rod which is attached to one of said form assemblies and threadably engaged within said embedded attachment;
- and
- (f) repeating the steps labeled (b), (c), (d) and (e) for each pair of vertically adjacent structural concrete slabs to construct a plurality of succeeding structural diaphragm slabs.
