Building system

Claim 2

A building system comprising a pair of spaced precast bearing wall panels disposed parallel to one another, a series of precast floor planks extending between said bearing wall panels seated on said upper surfaces of said bearing wall panels with the ends of said planks being spaced inwardly from the outside surface of said bearing wall panels, a plurality of junction components, each said junction component including a body portion having an upper surface including a downwardly inclined outer portion and a lower surface, a depending seal lip extending downwardly from the outer edge of said lower surface, the lower surface of each said junction component being seated on the upper surface of each said bearing wall panel adjacent to but spaced from the adjacent ends of the floor planks with said seal lip overlying the upper outer edge of said bearing wall panel, seal structure on said upper surface of said junction component, and securing means disposed in the space between each said junction component, the adjacent bearing wall panel and the adjacent ends of said floor planks to secure said bearing wall panel and said floor planks together.

Claim 3

The system as claimed in claim 1 wherein said junction components are shorter than said bearing wall panels and a plurality of said junction components are disposed in abuttIng end to end series along each said bearing wall panel, and further including a seal component secured between the adjacent end surfaces of said junction components.

Claim 4

The system as claimed in claim 2 wherein the adjacent end surfaces of said junction components each include a groove extending from top to bottom of the component and said seal component is an elongated strip member disposed with its edges in the opposed grooves and extending across the space between said grooves.

Claim 5

The system as claimed in claim 3 wherein each said junction component further includes inclined drain channels for conducting condensate downwardly.

Claim 6

A building system comprising a pair of spaced precast first bearing wall panels disposed parallel to one another, a series of precast floor planks extending between said bearing wall panels seated on said upper surfaces of said bearing wall panels with the ends of said planks being spaced inwardly from the outside surface of said bearing wall panels, at least one junction component seated on the upper surface of each said first bearing wall panel adjacent to but spaced from the adjacent ends of the floor planks, each said junction component including a depending lip extending downwardly from its lower surface, said lip overlying the upper outer edge of said first bearing wall panel, a pair of second bearing wall panels, each said second bearing wall panel having a lower surface seated in sealing relation to the upper surface of a corresponding junction component, post-tensioning means extending between the first and second bearing wall panels of each pair, and securing means disposed in the space between each said junction component, the adjacent bearing wall panel and the adjacent ends of said floor planks to secure said bearing wall panel and said floor planks together.

Claim 7

A building system comprising a pair of spaced precast first bearing wall panels disposed parallel to one another, a series of precast floor planks extending between said bearing wall panels seated on said upper surfaces of said bearing wall panels with the ends of said planks being spaced inwardly from the outside surface of said bearing wall panels, at least one junction component seated on the upper surface of each said first bearing wall panel adjacent to but spaced from the adjacent ends of the floor planks, each said junction component including a depending lip extending downwardly from its lower surface, said lip overlying the upper outer edge of said first bearing wall panel, a pair of second bearing wall panels, each said second bearing wall panel having a lower surface seated in sealing relation to the upper surface of a corresponding junction component, post-tensioning means extending between the first and second bearing wall panels of each pair, and securing means disposed in the space between each said junction component, the adjacent bearing wall panel and the adjacent ends of said floor planks to secure said bearing wall panel and said floor planks together.

Claim 8

The system as claimed in claim 5 and further including a curtain wall extending between each said pair of bearing wall panels, each curtain wall including at each end thereof structure secured to the adjacent bearing wall panel for supporting said curtain wall between said pair of bearing wall panels, a series of precast roof planks extending between the highest pair of bearing wall panels and floating joint structure coupling the outer edge of each outside roof plank to the adjacent curtain wall.

Claim 9

The system as claimed in claim 5 wherein each said junction component has projection means extending upwardly from its upper surface and the lower surfaces of said second pair of bearing walls include recesses for receiving said projecting means.

Claim 10

The system as claimed in claim 7 wherein said junction components are shorter than said bearing wall panels and a plurality of said junction components are disposed in abutting end to end series along each said bearing wall panel, the adjacent end surfaces of said junction components each include a groove extending from top to bottom of the component, inclined drain channels for conducting condensate downwardly and further including an elongated strip seal member disposed with its edges in the opposed grooves and extending across the space between said grooves.
