The present invention relates to a pre-assembly slab system for concrete wind turbine towers, wherein the pre-assembly slabs can be transported to the vicinity of the tower of another wind turbine in the same wind farm or in another wind farm and be reused for the assembly of this other tower. The invention further relates to a method for assembling the pre-assembly slab system for concrete wind turbine towers.

A foundation anchor system for a building structure is disclosed herein. The foundation anchor system includes a positioning member for setting and aligning a sill plate anchor component in a foundation wall of a building structure, an anchor member configured to be disposed in the foundation wall, and an anchor bolt configured to secure a sill plate member to the foundation wall. The positioning member includes a body portion, first and second downwardly extending tab portions for overlapping opposite sides of the foundation wall, and an anchor component engagement portion configured to removably engage an end of a sill plate anchor or an end of a sill plate anchor bolt. The anchor member includes a tubular body portion with a threaded interior bore, and a frustoconical skirt portion for retaining the anchor member in the foundation wall. An installation method utilizing the foundation anchor system is also disclosed herein.

A precast concrete wall on a prepared subgrade, comprises standardized, precast, reinforced concrete foundation, wall and cap modules. The cap modules include parapets on opposed sides and an elevated roadway therebetween. A plurality of tie down rods, each extending through the cap modules, two or more courses of wall modules and at least partially into the foundation modules. An optional anti-tunneling barrier is provided in the subgrade, below the foundation. A method of constructing the wall includes specifying standardized reinforced concrete foundation, wall and cap modules so that they can be manufactured by multiple suppliers, and providing a logistical model to minimize shipping costs by matching each point of fabrication with the appropriate point of delivery.

A cement form includes a first surface arranged vertically and configured to support a volume of cement, a second surface arranged horizontally and configured to contact a ground support surface. The cement form includes a foam material and has a wedge cross-sectional shape.

The present invention is an arch/building support system comprising two (or more) opposing wedges, at least one located at the base of each side of the arch, with the bases of the opposing wedges facing each other, the opposing wedges connected to each other by a semi-rigid flexible rod or rods. In a building structure, the flexible member could be rebar(s) made of one or various materials (metal, plastic, nylon etc.) with various degree of elasticity. The rebars could envelop the structure (around the outside or shell) or reside within it, and may also incorporate some sort of spring mechanism. The rebar(s) are anchored to the upper wedge on each side of the arch, but need not be, and could instead be anchored to the ground.

A cement form includes a first surface arranged vertically and configured to support a volume of cement, a second surface arranged horizontally and configured to contact a ground support surface. The cement form may include at least one of a foam material and a polymer material. The cement form may include a wedge cross-sectional shape.

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 is directed to a customizable, modular foundation system using blocks and post-tensioning for improved structural integrity of the foundation. In some embodiments, the improved foundation system is provided by post-tensioning a plurality of blocks together such that cables or bars used for tensioning run in different directions than any of the joint lines between adjacent blocks. In this way, there are no bendable joints between adjacent blocks. Moreover, in some embodiments the blocks are hexagonal, such that each block has six sides and post-tensioning cables can run in at least three different directions. Structures or apparatuses may be secured to the foundation comprised of multiple blocks, with the foundation being rigid, customizable, and both assembled and usable in any desired location.

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 floating foundation assembly includes a plurality of piers and one or more decks. The plurality of piers are screwed into or otherwise secured to a ground surface at predetermined distances from each other, at predetermined depths. The one or more decks include a precast prestressed deck with standardized geometries. The one or more precast prestressed decks are installed transversely across tops of the plurality of piers and are configured for affixing a structure above them. The one or more precast prestressed decks are manufactured in a controlled environment at an off-construction site, after which they are transported to a construction site and installed on top of the plurality of piers to form the floating foundation assembly. These resulting decks and supporting floating foundation assemblies have superior quality, durability, weatherproofing, and crack resistance.
