Abstract
This invention relates to a method of constructing a footing and a foundation wall thereon, and form therefore in a hardenable building material for use in a continuous, perimeter type building foundation. An improved shape for the footing and foundation wall is disclosed which allows the use of a novel formwork system, thus permitting both elements to be cast simultaneously in a monolithic arrangement. Additionally, the cast shape of the foundation system is such that the basic function of transmitting superimposed building loads to the earth is an improvement over the more traditional types of foundation systems. In the preferred embodiment of the invention, much of the formwork is expendable and is permanently left in place, being removed only where visable in the finished structure.
Claims39
A monolithic building foundation system, comprising:
- a plurality of horizontally elongated vertically planar members each having an upper planar portion and lower angled portion thereof, wherein each of said upper planar portions of each of said plurality of elongated vertically planar members further comprises an upper wall portion and a lower wall portion having weakened strip means disposed therebetween for separating said upper wall portion from said lower wall portion;
- top tie means for removably coupling a pair of said plurality of horizontally elongated vertically planar members in a generally parallel relationship with respect to the upper planar portion, wherein the lower angled portions of each member of the pair diverge from each other;
- and
- connection means for coupling each pair of said plurality of horizontally elongated vertically planar members in a generally end-to-end fashion thereby forming a unitary longitudinal chamber.
A method for constructing a monolithic building foundation comprising the steps of:
- excavating earth to form a trench;
- disposing within said trench a plurality of horizontally elongated vertically planar members each having an upper planar portion and a lower angled portion thereof wherein each of said upper planar portions further comprises an upper wall portion and a lower wall portion having weakened strip means disposed therebetween for separating said upper wall portion from said lower wall portion, in substantially parallel fashion such that each of said plurality of elongated vertically planar members corresponds and pairs with another of said plurality of elongated vertically planar members such that a continuous longitudinal chamber is formed therebetween;
- supporting each of said corresponding horizontally elongated vertically planar members to each other in paired fashion;
- bracing said paired and corresponding plurality of elongated vertically planar members to the adjacent earth;
- pouring a predetermined amount of a generally plastic material into said continuous longitudinal chamber thereby forming therein a monolithic foundation footing and wall simultaneously;
- removing a portion of said upper planar portion of each of said horizontally elongated vertically planar members after said plastic material hardens thereby leaving an upper foundation wall exposed;
- and
- backfilling around the monolithic building foundation system to a level grade.
