Embodiments of methods and apparatuses to measure a concrete foundation from within the concrete in order to maintain the foundation in a controlled flat condition over time we disclosed. A method, for example, may include placing a conduit network inside forms of a concrete foundation, documenting the conduit network in X and Y coordinate system, pouring the concrete foundation with the conduit network inside the concrete in generally the same position, passing an elevation measuring sensor through the conduit network to record a baseline elevation of the conduit and using this baseline for relative comparisons in the future. An embodiment of a method also may include using the relative change in the conduit elevation to predict the relative risk of a repair and financial losses and using the relative change in the conduit elevation to assist in the proper repair and maintenance of the foundation.

A method of constructing an inhabitable underground structure is disclosed that comprises the steps: creating a cutout in the earth at a desired location to generally match a desired shape of an interior of the underground structure; applying a reinforcement structure to an outer perimeter of the cutout; and applying shotcrete over the reinforcement structure to create a monolithic underground structure.

A cooling tower structure having a concrete perimeter foundation wall with a perimeter rebar grouping. The structure includes at least four columns formed of CMU blocks with at least two columns being freestanding and positioned approximate corners of the foundation wall. Each column further includes a column rebar grouping being tied into the perimeter rebar grouping. At least three bond-beams formed of CMU blocks are connected between the columns at least four feet above the foundation. The bond-beams include beam rebar groupings tying into at least one of the column rebar groupings. The structure includes housing walls formed of CMU blocks extending upward from the bond beams. At least one fan is on at least one pedestal column positioned within the foundation wall, with a pedestal rebar grouping extending though the pedestal column from a concrete pedestal footing. A series of water collection troughs are positioned within the cooling tower above the fan and fill media is positioned in the cooling tower above the collection troughs.

The deck block has is made of plastic by a roto-moulding process. The deck block has a truncated pyramidal shape with a flat top plane, a hollow center; a uniform wall thickness; a central vertical post socket and four joist slots extending horizontally from the post socket at a right angle with each other. The deck block has a multi-wall pillar therein extending between a bottom surface of the post socket and a bottom plane of the block. This pillar is made of four vertical hollow oval-shaped columns that are arranged in a circular array under the post socket for reinforcing the bottom surface of the post socket. In another aspect, the joist slots have protruding lips on each side thereof, for enlarging a top surface of the block and for reinforcing the joist slots.

An anchor bolt device for securing a structural member to a concrete foundation is described. The anchor bolt device includes a first anchor bolt, which has an enlarged portion, a shank portion, and a tail portion. The enlarged portion extends from a first end of the first anchor bolt and has an enlarged portion cross-section. The tail portion extends from a second end of the first anchor bolt and has a tail portion cross-section. The shank portion is disposed between the enlarged portion and the tail portion and has a shank portion cross-section that is smaller than the enlarged portion cross-section. A first coupling is disposed at the first end of the first anchor bolt for securing the first anchor bolt to the structural member. A second anchor bolt may be coupled to the second end of first anchor bolt at a second coupling.

Disclosed herein are support column structures which can be used to support bridges, buildings or other structures. In some cases, a support column structure can be deconstructable and include one or more removable elements. In some cases, a support column structure can include shape memory alloy reinforcing bars. In some cases, a removable element of a support column structure can include an engineered cementitious composite. In some cases, a removable element includes one or more sleeves to separate an engineered cementitious composite from one or more shape memory alloy reinforcing bars. Methods include assembling and disassembling a support column structure.

A mounting base (10A) that shortens construction time and reduces cost is formed from a metal foundation (16), a metal cover (17), height-adjusting bolts (18), support bolts (19), and mortar (20). In the base (10A), the first fixed ends (47) of the bolts (19) are inserted into support bolt insertion holes (39) formed in a metal plate (24) and are fixed to the metal plate (24) with nuts (50), and the second fixed ends (48) of the bolts (19) are fixed to a concrete slab (12) with nuts (51). The portion of the first fixed ends (47) of the bolts (19) which extends between the metal plate (24) and the top surface of the concrete slab (12) is integrated with the mortar (29) filled into the space (46), and the metal cover (17) covers the opening (27) at the top of a metal tube (23).

A foldable building structure includes a wall assembly made from a semi-rigid continuous sheet material configured with creases that enable the sheet material to be bent or folded to form multiple integrally formed together walls. A roof assembly can be formed from a second semi-rigid continuous sheet material that is configured with creases that enable the sheet material to be bent or folded to form multiple integrally formed roof panels. A floor assembly can be made out a third semi-rigid continuous sheet of material that also can be folded to form foundation members and floor panels.
