A volumetric modular unit constructed at a modular unit factory and shipped assembled to a modular building project site is disclosed. A modular building constructed from shipped volumetric modular units is also disclosed. Features of a volumetric modular unit and modular building are designed to account for and leverage traditional building practices. Shipping constraints often dictate volumetric modular unit design constraints. The volumetric modular unit and modular constructed building addresses both design needs and shipping constraints to leverage more economical resources available at a volumetric modular unit manufacturing plant.

A modular assembly is provided and includes a modular frame to be installed at least partially below grade and at least two panels attached to the modular frame, where the at least two panels are made of a material that withstands lateral, vertical and shear forces generated by surrounding below grade materials. The modular frame and the at least two panels are joined together as a unit prior to installation.

A factory-built home that is capable of being constructed on a concrete foundation slab is disclosed herein. The home is broken down into a plurality of small functional modules that are supported in a manner that facilitates connection to the concrete foundation slab. For example, a plywood subfloor or a lumber bracing system may be used.

Readily joining CLT panels to obtain a box-shaped building unit.

An orthogonal part of each surface of a rectangular parallelepiped has a structure wherein a surface of edge of lumber 11s of a CLT panel 11 is made abut on an inner main surface 10i of a CLT panel 10 and joined thereto by a joining member 2 so that a surface of edge of lumber 10s of the CLT panel 10 and an outer main surface 11o of the CLT panel 11 are flush. A joining part by the joining member 2 has a structure wherein the surface of edge of lumber 10s and the inner main surface 10i and outer main surface 10o of the CLT panel 10 are opened so that the outer main surface 10o side is wider than the inner main surface 10i side, the surface of edge of lumber 11s and at least the outer main surface 11o of the CLT panel 11 are opened so that the inner side of the CLT panel 11 is wider than the surface of edge of lumber 11s side, and the butterfly joint-shaped joining member 2 is inserted into the opening of the CLT panel 10 and the opening of the CLT panel 11 from the surface of edge of lumber 10s of the CLT panel 10 and the outer main surface 11o of the CLT panel 11 side.

The modular system for constructing a timber-framed building includes a plurality of timber-framed modules which each have a rectangular parallelepipedal cross-section and are composed of a series of vertical posts which are continuous up the entire height thereof and are interconnected in pairs by at least two horizontal joists . At least two modules are assembled horizontally, thereby defining a wall between those modules. At least two timber-framed modules are assembled vertically, so at least one wall post is provided between vertical posts. The wall posts of horizontally adjacent modules are offset with respect to one another and overlap, at least in part. The posts of an upper module rest on the posts of a lower module, directly or indirectly by a layer of non-compressible material. The invention further relates to a timber-framed building having at least one modular system of this type.

A composite construction element or panel system for use in construction of multi-storey structures, either as a prefabricated panelized system or as a modular system. The composite construction element comprises two mass timber subpanels joined at a distance to form a hollow core, through which various building services (e.g. HVAC or electrical systems) and/or insulation may be integrated. When used as a modular system, after assembly, the two subpanels become one structural entity of increased structural capacity while providing a hollow core to provide/deliver desired building services.

A system for securing modular building units to each other and a method for assembling structures using said method is disclosed. The disclosed system allows for modules to be connected to each other from an external position, without a person having to enter the modules to fasten components internally. The system and method may be used to build structures using prefabricated modules, avoiding significant amounts of onsite labor and drastically reducing the time required to erect structures.

The invention relates to a construction element for attachment of structural elements. The element comprises an upper plate member and a lower plate member, having a same width and a same length and extending between two end portions, parallel to each other at a first distance. The upper and lower plate members are connected to each other along longitudinal sides of said plate members by means of a plurality of intermediate beams. Each end portion further comprises at least one upper and at least one lower distance element having a width and a height, and being arranged at an upper surface and a lower surface of said end portions respectively. A longitudinally transversal cross section of each end portion forms a cross-shaped circumference, said circumference comprising four right angled abutment surfaces, defined by the plate members and the distance elements. The invention also relates to a module and a construction comprising such a construction element and a method of assembly of such a construction.

A method of manufacturing wall elements for buildings, cross laminated timber panels of a specific width and length stocks in a store, and the panels are sawed up transversely to the longitudinal direction to obtain cross laminated timber panels of the same width and smaller length. A plurality of panels are placed onto a conveying track transversely to the direction of running, and indeed such that the panels are flush at the top and bottom and the side edges of consecutive panels contact one another. The panels on the conveying track are connected along the contacting longitudinal sides to form a cross laminated timber apron. The apron is sawed up transversely to the direction of running of the conveying track to obtain cross laminated timber boards of a defined width.

A modular assembly is provided and includes a modular frame to be installed at least partially below grade and at least two panels attached to the modular frame, where the at least two panels are made of a material that withstands lateral, vertical and shear forces generated by surrounding below grade materials. The modular frame and the at least two panels are joined together as a unit prior to installation.
