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.

A beam system and method of erecting a supporting arch enables large roofed structures to be erected quickly and economically. The method includes aligning a plurality of structural elements longitudinally; connecting upper corners of the structural elements to upper corners of adjacent structural elements, wherein adjacent lower corners of the structural elements remain unconnected; elevating first and second structural elements in a middle of the supporting arch; connecting lower corners of the first and second structural elements together; elevating third and fourth structural elements adjacent the first and second structural elements, respectively; and connecting lower corners of the third and fourth structural elements to lower corners of the first and second structural elements, respectively.

Disclosed herein is the fabrication and implementation of prefabricated volumetric construction modules that include transitioning members that adjust between vertical support columns and structural trusses via lateral joints. Modification of vertical support columns to trusses enables open space configurations in volumetric construction. Each volumetric module includes a habitation zone and a truss zone. Folding or transitioning a vertical support column at the lateral joint positions a lower region of the support column from the habitation zone into the truss zone. The vertical support columns are transitioned in a specified order where within a given row of vertical support columns. Beginning from a first interior column on an edge-positioned transforming volumetric module, workers fold half of the vertical support columns of the given row into the truss arrangement in a first direction toward the edge-positioned transforming volumetric module. Continuing from a second interior column on an opposite edge-positioned transforming volumetric module, a worker folds a remining half of the vertical support columns of the given row into the truss arrangement in a second direction toward the opposite edge-positioned transforming volumetric module.

A modular building section defining the roof and opposing walls of a modular clearspan building. The building section includes a roof portion extending in a longitudinal direction between opposite first and second ends, and a pair of first and second legs, each leg pivotally attached about a pivot axis to the roof portion proximate a roof portion end. Each of the first and second legs has a stowed position in which the leg generally extends in the longitudinal direction and is in superposition with the roof portion, and an expanded position in which the leg depends from the roof portion and generally extends perpendicularly to the longitudinal direction. The legs are moveable independently of each other from their respective stowed positions to their respective expanded positions under the influence of gravity during lifting of the roof portion. Also disclosed are methods for constructing a modular clearspan building.

A structure is able to be collapsed when tension is not applied to a main tension member. As tension is applied to the main tension member, the tension member aligns and brings tension path components together so as to automatically assemble the tension path components and erect the structure.

A drilling rig mast erection system includes a mast support shoe that is fixedly attached to a drilling rig substructure and has a support shoe pinned connection. A bottom mast section has a first mast pinned connection that is adapted to be pivotably connected to the support shoe pinned connection. A mast positioning apparatus is adapted to pivotably position the bottom mast section so that the first mast pinned connection is positioned adjacent to the support shoe pinned connection.
