A bracket includes a first wing, a second wing and a bridge that connects the first wing to the second wing. The first wing has a first inner surface and a first outer surface. The second wing has a second inner surface and a second outer surface. The bridge extends from the first inner surface to the second inner surface thereby coupling the first wing to the second wing such that the first inner surface is normal to a first direction, and the first inner surface is parallel to the second inner surface. The bridge includes a front edge and a rear edge. The front edge forms a recess that extends into the bridge towards the rear edge along a second direction that is perpendicular to the first direction, and the recess terminates within the bridge prior to reaching the rear edge.

A lightweight transportable containerized shelter includes wall panels made of a non-metal composite material coated at least on its inner face with a metal layer for EMI protection. The several wall panels are secured to a metal structural frame without the use of fasteners so as to define a containerized transportable shelter. The shelter meets ISO standards 668 and 1496. The shelter provides a continuous barrier to electromagnetic signals. Moreover, the containerized shelter is amenable to nine high stacking as required for ISO certification.

A module for a structural system may include chords oriented along a length of the module and a plurality of rib assemblies positioned between the chords. Two of the rib assemblies may include shear keys configured to be received in piers at a final installation site. A method of making a structure may include positioning the shear keys in pockets of the piers.

A support stand for supporting a volumetric modular unit above the ground is disclosed. The support stand includes a top portion with a top surface for contacting and supporting an underside of the modular unit above the ground. A bottom portion with a bottom surface supports the top portion at an elevation above the ground against the underside of the modular unit. An elevating portion has a top side connected to the top portion, a bottom side connected to the bottom portion, and an elevating span between the top side and the bottom side. A pad is connected to the bottom portion. The pad has a bottom surface for contacting and supporting the bottom portion against the ground, an inner pad perimeter and an outer pad perimeter. The top surface is parallel with the bottom surface. The underside and weight of the modular unit is supported on the top surface.

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.

Modular building cleanrooms having integrated mechanical rooms with removable, walkable floor panels above their ceilings are disclosed. The attic area above the sealed cleanroom ceiling and below joists of the modular building's frame provides an interstitial volume through which ducts, piping, electrical conduit, etc. run from the mechanical room to dampers, valves, and junctions boxes. The walkable floor panels can be bar grating through which maintenance people can see components below. The floor panels can have individual sections that may be removed for access to the components. Along with walkable floor panels, the modular building roofs can have foldable electrical panelboards that are pre-wired at the factory and then rotated upright once delivered to their destination.

The top surface is parallel with the bottom surface. The underside and weight of the modular unit is supported on the top surface.

The invention is directed broadly to a modular housing system having a structural framework comprising an internal chassis as a core structural element, the internal chassis including: a first ladder frame that defines a base; four columns at least two being extendable columns; and a second ladder frame engaged to the first ladder frame via the four columns, such that at least one of a distance and an angle between the first ladder frame and the second ladder frame is adjustable to define a usable volume of the structural framework.

Disclosed is a building module for use in modular building assemblies. The building module has frame comprising one or more parallelepiped unit cells and connection nodes at the corner of the unit cells, so that building modules can be connected together in a modular fashion using the connection nodes. Also disclosed is a system for building construction that comprises such building modules, and habitable modular buildings that comprises the building modules.

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.
