An exterior wall section forms a portion of an exterior wall of a building. The building has multiple floors and a framework defining the multiple floors. The exterior wall section includes a structural layer to be connected to the framework. The structural layer includes a plurality of studs connected together. An insulation layer is supported by the structural layer to insulate the building. Siding is supported by the structural layer and defines an exterior side of the exterior wall section. A perimeter of the exterior wall section is defined by the edge margins of the structural layer, the insulation layer and/or the siding. The exterior wall section includes an interlocking structure extending along the perimeter that mates with an interlocking structure of another exterior wall section to form a seal with said another exterior wall section when the exterior wall sections are connected to the building.

The invention concerns the construction process and can be employed in the course of construction of buildings and structures of different purposes in order to reduce labor consumption during formation of floor slabs, and to facilitate integrity retention of a slab and hoisting equipment during the rotation operation. The carcassing method assumes simultaneous construction of bearing solid-cast reinforced-concrete structural vertical elements and hinged to them vertically oriented reinforced-concrete pivot floor slabs. The construction process involves preliminary installation of separating elements between slabs and bearing structures as well as between adjacent slabs. After the concrete has developed its strength, the above slabs shall be flipped to the horizontal position and butt joints between slabs and bearing vertical elements as well as between adjacent floor slabs shall be grouted. The vertical elements and floor slabs are formed in layers, vertical partition elements represent sheet-type or film-type polymer materials, the pivot hinge of floor slabs represent an elongated element located in the middle portion of a floor slab and whose longitudinal axis coincides with the slab rotation axis. Bearing elements shall be formed as columns. Tubular round-in-section hinge elements of horizontally adjacent floor slabs shall be located at opposite sides of the longitudinal axis of a column. Floor slabs shall be reinforced by a prestressed reinforcement cage made of a sheathed steel cable. Tendons shall be installed inside of floor slabs after their formation. For this, the solidifying grout is fed into cavity of the slip formwork inside a slab, linear voids are formed by means of channel formers. The longitudinal axis of a hinge runs through the mass center of a floor slab. Slabs shall be flipped in the ascending and descending order. Channel formers shall be shifted upon shifting the formwork or upon transition to the next layer. Channel formers shall comprise the broach for installation of tendons in channels. Channel formers are equipped with vibrators for compaction of the grout. After rotation of slabs, the reinforcing cable shall be placed inside transverse channels and shall be tensioned.

The present disclosure provides an insulation system for a building. The insulation system comprises a wall section adapted to be installed at least partially between two vertically oriented posts of a building, and a base section configured to be interconnected to the wall section and comprising a surface extending outwardly and downwardly away from an outer surface of the wall section when the insulation system is installed at the building.

Methods and apparatus facilitate the construction of a building using prefabricated building units, each having a horizontal upper exterior surface and a plurality of vertical wall surfaces, wherein at least some of the prefabricated building units have at least one hollow column formwork structure. The prefabricated building units are lowered onto a pre-existing base at a construction site. A first story of the building is created by arranging a plurality of the prefabricated building units adjacent to each other on the base. Structural bearing material is applied to fill the hollow column formwork structures to create structural columns connected to the structural deck. Structural bearing material is applied to the horizontal upper exterior surfaces of the adjacent prefabricated building units to create a single structural deck over the prefabricated building units.
