A method for constructing a building structure using gravity and weight of the building structure is provided. The method includes designing an architecture and a construction plan of the building structure, planning an initial box for a structural design, tuning a ground required for construction of the building structure, constructing the initial box as per the planning, constructing an upper floor on the initial box, constructing remaining parts of the building structure including foundation for the building structure, and assembling a plurality of temporary structures to the building structure.

Disclosed are interlocking steel plate foundations of various configurations. Interlocking foundations eliminate the need for concrete foundations and have a much shorter assembly time. Interlocking foundations have fins which provide for increased torsional restriction for the same or less material than other metal foundations such as the metal fin tube style foundation. Optionally multiple foundations can also be linked together to construct foundations of any shape and size

A system for mounting an anchor bolt to formwork or other structures associated with concrete construction includes a main body and latch coupled to the main body. The anchor bolt can pass through the main body and the latch can be moved so that threads formed in the latch engage threads formed in the anchor bolt to secure the anchor bolt in position as concrete is poured around the anchor bolt. The main body and the latch can have through holes for receiving a nail to lock the position of the latch with respect to the main body.

This disclosure describes devices and methods for forming voids in or adjacent concrete structures. In some embodiments, a device may include a structure. The structure may be substantially planar. The structure may include a plurality of channels extending therefrom. In some embodiments, the channels are closed at a first end distal from the structure. In some embodiments, the channels are open at a second end proximal to the structure. In some embodiments, the device may be formed from a molded pulp. The molded pulp may be configured to inhibit penetration of water. In some embodiments, the device may be configured to substantially support poured concrete during at least a portion of a curing process of the poured concrete.

A landscape edging block can include a shaped structure having a first and a second end. The first end can include a surface that is concave simultaneously along a horizontal plane and a vertical plane. On the contrary, the second end can include a surface that is convex simultaneously along a horizontal plane and a vertical plane. The shaped structure can include a top and sides configured to resemble decorative stone. Additionally, first end of the block can be configured to engage a second end of a second block in order to form a landscaping border.

A ballast block has a uniquely designed framework consisting of lightweight, pre-fabricated, metal panel members and cross-bracing and elongated bracing members. The various components of the ballast block framework are compactly bundled and shipped to the end use location for assembly on-site. Once assembled, the ballast block framework is properly positioned on its permanent, end use location and concrete or equivalent ballast material is poured into the framework, completely filling its internal space. The ballast block can be sized and fabricated for the specific desired purpose.

A nuclear island base slab of a nuclear power plant and a manufacturing method therefor, and a nuclear island of a nuclear power plant. The nuclear island base slab of a nuclear power plant includes a concrete base slab body and a plurality of air ducts embedded in the concrete base slab body. The air duct has an internal-penetrating bent pipe structure. A first end of the air duct is exposed on an upper surface of the concrete base slab body. A second end of the air duct is exposed on a side surface or the upper surface of the concrete base slab body.
