A secure and mobile retail structure for securely storing and selling restricted access products is provided. In one embodiment, a vault wall located between a first end wall and a second end wall dividing the interior volume, from the vault wall to the first end wall, into a vault area for securely storing therein the restricted access products, and, from the vault wall to the second end wall, into a service area for serving customers. The vault wall comprises a secure access doorway to provide restricted access to the vault area from the service area. In some embodiments, the structure compromises one or more passive mobility means operable to be used for moving said structure from one location to another location. In some embodiments, the structure is integrated into a motorized vehicle.

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 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.

A modular construction system comprising: a main connector having a body and an integrally formed rod, the rod having a rod tubular body, a rod insertion end, and a rod hollow chamber traversing the rod from the rod tubular body through the rod insertion end, and wherein the rod is radially disposed about the body; a plurality of main bars, the main bars having a first receiving end, a main bar tubular body, a second receiving end, a main bar hollow chamber traversing the main bar from the first receiving end through the main bar tubular body to the second receiving end, at least three main bar longitudinal sides, a plurality of apertures on the main bar longitudinal sides, and at least three main bar grooves between adjacent main bar longitudinal sides, the main bar grooves being parallel with the main bar tubular body and the main bar hollow chamber.

A variable shape three-dimensional structure includes: an upper frame; a lower frame; and a longitudinal coupling member that couples the upper and lower frames. Each of the frames includes cross units and an end coupling portion. Each cross unit is formed by two rigid members crossing each other and pivotally coupled together. The end coupling portion pivotally couples the ends of the rigid members of the cross units. The longitudinal coupling member includes a bent unit comprising a first and second bent rigid members, and a bent portion coupling shaft. The first and second bent rigid members are bent in a V-shape. The bent portion coupling shaft pivotally couples the bent portions of the first and second bent rigid members. The upper end of the bent unit is coupled to the upper frame and the lower end of the bent unit is coupled to the lower frame.
