The center point of the arc of the slot is located on the corner junction line. The interengagement of the pins with the slot affords a link type guidance between the formwork units. As a result, forces are transmitted at the corner junction line only in the assembly state so that the line lies practically in the plane of the formwork surface which define the concrete surfaces.

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.
