Abstract: The earth sheltered building consists of a thin elliptoidal shell which is attached to a generally curvilinear top viewed foundation. The elliptoidal shell meets the foundation at a generally horizontal latitudinal plane which is spacially below and parallel to the equatorial plane of the elliptoid. The building has ingress and egress means defined generally by the intersection of a pair of latitudinal lines and a pair of longitudinal lines of the elliptoid. Ingress and egress means can also be obtained by the omission of any meridian surface section of the elliptoid or any section defined by a plane spacially parallel to a meridian plane. The building can also be elongated by placing a vaulted section of elliptic vertical cross section congruous with two hemi-elliptoidal shells. The building can be constructed by the use of predetermined inner and outer form panels which assemble into inner and outer form networks.

The fact that each upper column member is separately supported by an adjustable device that assures proper vertical positioning, means that there are minimal bending stresses in the upper and lower beams during the heavy loading which occurs when supporting poured concrete, so that the structural members can be constructed of a material of high strength but low rigidity such as aluminum.

Abstract: A construction system for constructing multistory buildings is disclosed. Concrete joists are poured in place, using high-strength concrete. The concrete is poured into a removable, reusable ganged-form structure. The sides of the joist forms swing away from the joists after the concrete is set. Monolithic slab soffits, comprising an underlayer of gypsum board and an overlayer of concrete are pre-cast and moved into place to connect the joists before pouring of the joist concrete. The combination of pre-cast soffits and poured-in-place joists permits rapid and inexpensive construction of the multiple floors of a building. Alternatively, the slab soffit may be poured in place, in the same pour as for the joists, by placing fire-resistant boards between adjacent joist forms, thereby eliminating the need for cleaning any form work in those areas.

Abstract: Apparatus for constructing reinforced concrete modular construction units comprising longitudinally extending multi-sided construction units. Reinforcing bars and mesh are formed into a cage of the desired size and shape for the particular unit. Such cage is mounted on a rotatable shaft which may also be raised and lowered relative to a horizontal bed. Each side of the modular construction unit is in turn positioned in a perimeter form on the bed in which the concrete is poured and finished flat to form each side of the modular unit. After each side has cured a sufficient time to insure its structural integrity the cage is raised and rotated to align another side of the cage with the horizontal bed. The cage is lowered into position adjacent the bed in a suitable form and concrete is poured around the reinforcing structure on that side of the cage to form that side of the wall of the building. Successive sides are similarly formed until the longitudinally extending hollow construction unit has been completed.
