A method of constructing a modular building, the method can include the following sequential steps: constructing a multi-floor building frame by connecting a plurality of like open topped-trays and column assemblies, with the trays forming floors and the column assemblies separating the floors; assembling walls or walls formwork to the frame; and pouring wet concrete into the trays to form the building.

A wall of a building structure, the wall comprising: inner and outer face surfaces formed from glass fibre reinforced board; a support structure comprising one or more rigid components positioned between the inner and outer face surfaces; and a quantity of low-density cellular lightweight concrete (CLC) which substantially fills the space between the inner and outer face surfaces.

The invention relates to a method for constructing a roof, the roof being intended for a building having a perimeter enclosure, the method having the production of a formwork configured to support the roof during its construction and to allow the casting of a slab, the construction of a supporting structure configured to ensure that the roof is mechanically resistant and that the roof is attached to the building receiving the roof, the casting of the slab performing a bonding material function, the slab being configured to transfer mechanical stresses within the supporting structure, and the construction of an external girdling, referred to as a cornice, connecting the roof to the building by girdling both a portion of an outer surface of the perimeter enclosure of the building and a portion of the girdling structure attached to the building, in order to increase the mechanical resistance of the roof to being torn off.

An inference system for monitoring a cementitious mixture for three-dimensional printing is provided. The inference system includes an ambient condition sensor, a temperature sensor, a moisture sensor and an image capturing device. The inference system also includes a controller coupled to the ambient condition sensor, the temperature sensor, the moisture sensor, and the image capturing device. The controller receives sensed ambient conditions, a temperature signal, and a moisture content signal. The controller receives an image feed of a portion of a cementitious mixture. The controller also receives signals indicative of a motor speed and a motor torque associated with a mixing container. The controller builds a model and determines a material suitability of the cementitious mixture using the model based on the received ambient conditions, the temperature signal, the moisture content signal, the image feed, the motor speed, and the motor torque and determines one or more corrective actions.

A method of construction of composite wall module system in which a first wall module and a second wall module are coupled to the first wall module by a vertical joint. The vertical joint is comprised of plurality of anchors and reinforcement bars as well as steel side plates allowing composite wall steel faceplates to be discontinuous across the vertical joint. The faceplates of the first and second modules are not made continuous across the vertical joint through continuous welding. The vertical wall joint further includes fill disposed between faceplates and side plates adjacent to anchors and reinforcement bars.

The present disclosure relates to components and methods for a modular building system, used for high-rise residential and office building, to pre-fabricate and assemble the system quickly, easily and simply. More particularly, it relates to a building temporary self-supporting panel system invention that includes formwork, structural rebars and insulated panels for the purpose of wall, floor and roof, also for the structure and enclosure. The building system is composed of a number of layers and a temporary-structural frame, integrating all constructive elements needed: temporary structural capacity, thermal and acoustical insulation, impermeability and pre-installations; designed considering operation, function, fabrication and assembling.

A device for fabricating structures of large dimensions, layer by layer. The invention relates to a device making use of positioning an extrusion head in three dimensions by means of cables in order to deposit a pasty material continuously in thin layers, e.g. a mortar comprising either a hydraulic binder or thermoplastic compounds or thermosetting compounds or curable compounds. The invention is for making industrial elements of very large dimensions, and more particularly for making buildings.

A method of tensioning concrete is disclosed.

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.
