Abstract
Concrete slab foundation and method of construction in which ground soil is graded to form a building pad, a plurality of plastic domes having top and side walls are placed in a rectilinear array on the pad, and concrete is poured over the domes to form a monolithic structure consisting of a gridwork of criss-crossing ribs between the side walls and a horizontally extending deck above the top walls. The concrete is prestressed with longitudinally extending tendons in the ribs, and the plastic domes are left in place as a permanent part of the foundation to serve as a moisture barrier at the under side of the deck and the lateral faces of the ribs.
Claims12
In a concrete slab foundation constructed on a pad of ground soil:
- a plurality of plastic domes arranged in a rectilinear array on the pad, each of said domes having a horizontally extending top wall, four side walls and an open bottom, a monolithic concrete structure poured over the domes consisting of a gridwork of criss-crossing ribs between the side walls and a horizontally extending deck above the top walls, tendons extending longitudinally within the ribs and prestressing the concrete, and the plastic domes serving as a moisture barrier at the under side of the deck and the lateral faces of the ribs.
In a method of constructing a concrete slab foundation on ground soil, the steps of:
- grading the soil to form a building pad, placing a plurality of plastic domes having top and side walls in a rectilinear array on the pad, pouring concrete over the domes to form a monolithic structure consisting of a gridwork of criss-crossing ribs between the side walls and a horizontally extending deck above the top walls, prestressing the concrete with longitudinally extending tendons in the ribs, and leaving the plastic domes in place as a permanent part of the foundation to serve as a moisture barrier at the under side of the deck and the lateral faces of the ribs.
In a method of constructing a concrete slab foundation on ground soil for a building having different floor levels, the steps of:
- grading the soil to a plurality of different levels to form a building pad having different levels corresponding to the different floor levels, placing a plurality of plastic domes having top and side walls in a rectilinear array on each level of the pad, the domes on the different levels all being of equal size, pouring concrete over the domes to form a monolithic structure consisting of a gridwork of criss-crossing ribs between the side walls and a horizontally extending deck above the top walls, the ribs all being of uniform height and the deck being of uniform thickness throughout, prestressing the concrete with longitudinally extending tendons in the ribs, and leaving the plastic domes in place as a permanent part of the foundation to serve as a moisture barrier at the under side of the deck and the lateral faces of the ribs.
