The invention relates to a foundation for a wind power plant, wherein the foundation (10) comprises substantially prefabricated elements, preferably of reinforced concrete, with a first, vertically extending base-like section (11), on which a tower of the wind power plant can be arranged, and a second, substantially horizontally extending section (12) as foundation body, which is in contact with the ground (100), wherein the first section (11) is arranged above the second section (12). Thereby, according to the invention, it is provided that the first vertically extending base-like section (11) is formed of at least three layers (13, 16, 17) arranged one above the other, of which the upper and the lower layer (13, 17) comprise at least two ring-like layers (13a, 13b, 17a, 17b) and the middle layer (16) is formed from at least one ring-like layer (16a), in that the height (H+I, 2I) of the upper and/or lower layer (13, 17) is less than the height (J) of the middle layer (16), and in that the layers (13, 16, 17) are vertically braced to the second section (12) by means of at least two vertical tendons (19).

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.

The present disclosure discloses a modular building for civil use, which comprises a wall panel (6), a floor panel (5), a vertical column, and a foundation block (1). A protrusion (11) is provided at a center of a bottom surface of the foundation block (1), and a recess (12) is provided at a center of a top surface of the foundation block (1). A protruding post matched with the recess (12) of the foundation block (1) is provided at a bottom part of the vertical column. An engagement structure for connecting with the wall panel (6) and/or the floor panel (5) is provided on the vertical columns.

A concrete chair elevates rebar above an underlying surface. The chair includes a rectilinear rim having a length, width and height of different distance. The rim may be oriented so each side abuts the underlying surface so rebar can be supported at three different heights above the underlying surface. In a foundation pour, the chair supports rebar at three different elevations. In a tilt wall pour, the chair supports rebar at three different elevations and produces a mark on the cured wall of considerably reduced extent.

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.

A wall unit (V) for a retaining structure (100) comprises a foot portion (1a) and a wall portion (1b), wherein the wall portion (1b) is inclined with respect to the foot portion (1a), so that it extends over the foot portion (1a). Accordingly, the wall unit (1) is stable during construction and assembly. A corner unit (7) for a retaining structure (100) is adapted to engage with two wall units (1). A retaining structure (100) comprises at least one wall unit (1).

A modular assembly is provided and includes a modular frame to be installed at least partially below grade and at least two panels attached to the modular frame, where the at least two panels are made of a material that withstands lateral, vertical and shear forces generated by surrounding below grade materials. The modular frame and the at least two panels are joined together as a unit prior to installation.

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 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.
