A modular support frame comprises trusses, purlins transverse to the trusses, and vertical posts supporting the various trusses. A supply of wedges permits flange-type connectors to be joined to complementary connectors throughout the foundation. The trusses are arranged end-to-end in parallel rows, each row comprising at least one pair of trusses or more depending on the desired size of the foundation. Vertical posts are positioned between the ends of each of the trusses within a row and at opposing ends of the row, and each post comprises a pair of flange-type connectors at predetermined heights. Each of the trusses is terminated at either end with a pair of complementary connectors such that adjacent in-line trusses can be mounted to the post between them and the outer pair of trusses can be mounted to the posts terminated the row. Purlins extend perpendicularly between the trusses in adjacent rows to reinforce the frame. To that end, the trusses comprise flange-type connectors and the purlins are terminated at either end with complementary connectors.

A modular foundation including plurality of prefabricated concrete modules defining an upper layer of modules including at least one internal passage opening onto at least its upper and lower faces, at least one lower layer of modules on which the upper layer at least partially rests, including at least one internal passage opening onto at least one of its sides and onto at least its upper face, this internal passage communicating at the level of the interface between the upper layer and the lower layer(s) with the internal passage of the upper layer in such a manner as to form at least one global internal passage in the foundation opening onto at least one side and onto at least the upper face of the foundation.

A system of stem wall foundation blocks is a set of reinforced precast, post-tensioned modular footing and stem wall foundation blocks with a unique interconnecting design optimized for both residential and commercial applications that eliminates the need for on-site manufacturing of a foundation mold. The apparatus provides a unique modular foundation design for a variety of applications within construction. A series of wall blocks of different shapes and arrangements interlock, thus enabling users to modify the dimensions of their foundation mold to a desired purpose. Engineered bolts and lapped connections enable the modular wall pieces to securely connect after they have interlocked. This arrangement enables construction workers to move the interlocking blocks into position and then begin pouring concrete inside to lay the foundation. The reinforced precast, post-tension modular footing, and stem wall foundation blocks are less expensive and more efficient for building and constructing residential and commercial foundations.

A foundation system for supporting a structure thereon comprising: a plurality of blocks, each block having at least three sides; at least two recesses formed in the at least three sides of each block; a plurality of connecting plates having a first end configured to be secured within a recess of a first block and a second end configured to be secured within a recess of an adjacent block such that the connecting plate extends between recesses of adjacent blocks to secure adjacent blocks together to form a foundation grid of said blocks; and enclosure panels mountable to said blocks along an edge thereof so as to form an enclosure about a perimeter of the foundation grid.

A construction module for a structure, comprising: a formwork member that includes a base, a pair of parallel side walls that extend upwardly from the base, and a pair of parallel end walls. The base, the side walls and the end walls define a cavity for reinforcement and concrete. A reinforcement member includes an upper portion and a lower portion. When the reinforcement member is located in the cavity and concrete fills the cavity, the lower portion of the reinforcement member and the concrete define an elongate beam.

The present invention relates to a building system and a method of making and assembling the building system. In particular, the present invention relates to a footing for a building structure, the footing comprises a plurality of precast concrete layers, each precast concrete layer comprising reinforcement bars and a plurality of apertures. The footing further comprises a base structure comprising a base plate and a plurality of alignment bars protruding from the base plate. The footing is configured such that when the plurality of precast concrete layers are positioned on top of one another, the plurality of alignment bars of the base structure extend through the respective apertures of each precast concrete layer. Furthermore, the present invention relates to a building structure having one or more building modules.

The present invention relates to a building system for erecting a building structure. The building system comprises a plurality of precast transportable concrete wall panels; each wall panel comprising a reinforcement structure and a plurality of cast-in connecting inserts, each connecting insert being located at a predetermined position; and a precast transportable concrete floor panel, the floor panel also comprising a reinforcement structure and a plurality of cast-in connecting inserts, each being located at a pre-determined position, the floor panel further comprising a recess along at least a portion of a perimeter of the floor panel. The building system is configured such that when each precast wall panel is positioned in a substantially upright position in the recess of the floor panel, connecting inserts of two adjacent panels align so that the panels can be connected using a plurality of mechanical fasteners.

A modular slab, slab system, piles and methods of use thereof are described along with specific applications and methods of manufacture. The slab or slab system may be pre-insulated and pre-finished before being assembled on site. The slab system may be advantageous to use as a replacement for traditional in-situ poured building foundations. The slab system may also have uses in other fields such as for floors, roads, bridges, pavements/side walks and other civil and structural applications.

A foundation for a wind power plant includes a circular or polygonal pedestal divided into several ring sections for carrying a tower and support elements extending radially outward from the pedestal, wherein the ring sections and the support elements are designed as prefabricated concrete elements or are assembled from prefabricated concrete elements, and wherein adjacent support elements are spaced from one another in the circumferential direction, adjacent support elements are each connected with one another by a tangentially extending beam designed as a prefabricated concrete element.

A post-tensioning system that is configured for use with concrete wind turbine foundation designs to post-tension the foundations and reduce the amount of reinforcement steel that is needed compared to conventional non-post-tensioned, steel reinforced concrete foundation designs. In the case of an inverted T gravity foundation, the post-tensioning system described herein reduces the amount of reinforcement steel that is required by 30-40 tons.
