Abstract

The building system employs precast corners (16) and elongated walls (12) with integral footings (14 and 18) to construct a foundation and basement. Precast first elongated wall sections (50) and corner sections (52) and floor slabs form a first level. Upper level wall sections (74), corner sections (76) and floor slabs (72) form an upper level. Gable sections (90), a ridge beam (92) and roof slabs (94) form a roof. The precast members all include a steel mesh reinforcement (102, 104 and 106). Sections are rigidly connected together at their ends (58 and 68) by connector assemblies (108 and 160) that are connected directly to the reinforcement (102). The sections are secured together by sheebolts (120) that extend vertically from a lower section into an upper section.

Claims19

Dependent claims

A building comprising a foundation formed from a plurality of precast lower level corner sections, each of which has a steel mesh reinforcement encased in concrete, an integral footing having a steel mesh reinforcement encased in concrete and sufficient area to be supported by soil, and at least one first end surface and one second end surface;

a plurality of precast lower level elongated wall sections each of which has a steel mesh reinforcement encased in concrete, an integral footing having a steel mesh reinforcement encased in concrete and sufficient area to be supported by soil, and at least one first end surface and one second end surface;
said wall sections with integral footings and said corner sections with integral footings are placed in positions with the first end surface on one section adjacent to and facing the second end surface on another section and forming said foundation with the desired shape and size;
and a metal connector assembly for holding the first end surface and the adjacent second end surface in subspositions fixed positions relative to each other, including members connected to the steel mesh reinforcement adjacent to the first end surface of one section, to the steel mesh reinforcement adjacent to the second end surface of another section, and to each other.

A method of building a structure including forming a plurality of precast lower level corner sections, each of which has a steel mesh reinforcement enclosed in concrete, an integral footing with steel mesh reinforcement encased in concrete, at least one first end surface and at least one second end surface;

forming a plurality of precast lower level elongated wall sections, each of which has a steel mesh reinforcement encased in concrete, an integral footing with steel mesh reinforcement encased in concrete, at least one first end surface and at least one second end surface;
preparing a generally flat surface at a construction site to support the lower level corner sections and the lower level elongated wall sections;
transporting the lower level elongated wall sections and the lower level corner section from a precast facility to said construction site;
positioning the lower level corner sections and the lower level elongated wall sections on said generally flat surface with a first end surface on some sections facing a second end surface on an adjacent section;
and connecting lower level corner and elongated wall sections to each other where a first end surface faces a second end surface on an adjacent section.
