A method of installing a reusable security barrier is presented that allows quick installation and removal. In one preferred embodiment, the method comprising providing precast concrete panels having a generally rectangular profile elevation, digging a foundation trench having a length equal to or longer than the panel width, lifting and placing the panel such that a portion of the panel is inserted inside the trench and a portion extends generally vertically upward from the trench forming a barrier, and filling and packing the portion of the trench unfiled by the panel with a filler material to provide a solid foundation. The method can further comprise utilizing multiple panels placed side edge to side edge with their bottom portions inserted inside a trench to form a longer security barrier. The method can further comprising removing the precast concrete panels from the trench for reuse in a second site security barrier when the original security barrier is no longer needed.

Precast wall systems and methods for constructing a high-rise building using the precast wall system is disclosed. In one embodiment, the system includes a plurality of interconnected precast panels, each having a top end plate, a bottom end plate, a plurality of vertical bars disposed between the end plates and a cementitious material encasing the vertical bars and defining a plurality of sides of the respective panel. A first of the precast panels has a first column member half defining a right side of the first panel, a second of the precast panels has a second column member half defining a left side of the second panel such that, when the right side of the first precast panel and the left side of the second precast panel are disposed horizontally adjacent to each other, the first column member half and the second column member half collectively form a column member.

The present disclosure relates generally to a precast wall having increased pouring resistance. The precast wall has a configuration by which resistance to the pouring pressure of concrete poured between outer and inner panels is increased, the configuration including rail members buried in outer and inner panels, link members disposed between connection members connecting the rail members in the outer and inner panels to act integrally, and coupling members.

The invention is related to a masonry reinforcement and to a dispenser therefore. The masonry reinforcement comprises a reinforcement strip that defines a strip plane and that is at least in one direction bendable. In the reinforcement strip multiple strip apertures are arranged along the longitudinal direction of the strip, each strip aperture comprising an aperture rim at the aperture rim or in the range of the aperture rim of some or all of the strip apertures rim serration members are arranged. The rim serration members are orientated inwardly. They can protrude out of the strip plane of the reinforcement strip in at least one direction.

The group of inventions relates to constructing structures, such as the buildings of nuclear power plants, which are erected from monolithic blocks or slabs made of concrete or reinforced concrete. A block or a slab contains a built-in container with components for the sorption extraction, from water, of radionuclides or toxic substances. The container has elements for feeding-in contaminated water and for evacuating treated water. An erection method includes building a structure using the said blocks or slabs. A method for manufacturing a building block or slab includes forming a body out of concrete, embedding into same at least one container having water-treatment components, and having fittings or flanges for feeding-in contaminated water and for evacuating treated water. The invention provides for safe operations when erecting structures, and prevents the spread of radionuclides beyond the boundaries of a structure.
