The present invention ensures convenience of installation and guarantees the assembled cross beam has good stability.

An assembled structure system includes a prefabricated member, a fastener and a locking member. The prefabricated member is provided with at least one cavity, and the fastener is assembled in the at least one cavity. At least one fastener is assembled in each cavity. The cavity includes an upper end surface, a lower end surface, a left end surface and a right end surface. The left end surface or the right end surface includes a vertical surface perpendicularly connected to the upper end surface and an inclined surface connected to the vertical surface. A connection angle between the vertical surface and the outer side of the inclined surface forms an obtuse angle. The inclined surface is connected to the lower end surface. The fastener includes a fixed surface, two side surfaces and a bottom surface. The fixed surface, the two side surfaces and the bottom surface are hingedly connected.

Herein is disclosed a latch mechanism for latching together extruded support members used to construct temporary partitions and the like. The latch mechanism consists of a latch and strike plate combination wherein a latch is placed at the end of one extrusion and a strike plate is positioned at the end of a second extrusion. The strike plate has hooks and the latch has a bail which is dimensioned to engage the hooks. Each of the latches are switchable between an unlocked orientation wherein the bail is free from the hooks and a locked position wherein the bail engages the hooks and biases the two extrusions together. The strike plate, bail, and hooks are dimensioned and configured such that up to four extrusions can be latched around a single fifth central extrusion.

A system for creating an enclosed room, such as an office, in an open space that has a floor and a ceiling. The system includes a support frame that is self-supported on the floor of the open space. The support frame includes a series of head rails supported by a series of vertical columns resting on the floor. The vertical columns support a series of wall panels and the head rails support a ceiling such that the ceiling is supported by the support frame independent of the wall panels. The ceiling of the enclosed room is created by a series of ceiling panels and at least one air intake panel and at least one air exhaust panel. The air exhaust panel includes an exhaust fan that removes air from within the enclosed room and draws fresh air into the enclosed room. The ceiling can include a plurality of adjustable louvers and lighting.

Connectors for a framing system, wherein each of the connectors includes pairs of flanges that extend in parallel away from a base.

A fast, flexible, and affordable structural building solution is disclosed. Current construction methodologies are prohibitively costly, slow, and wasteful. This construction method provides responsive and adaptive short to long term structural solutions. A reconfigurable flat packed modular structure can be shipped, assembled, and move-in ready in a fraction of the time of standard structural solutions. This system is easy to assemble and reusable with decreased maintenance costs and utilizes standardized shipping infrastructure. The structural elements are designed to build flexible residential, commercial, and industrial spaces. Component standardization reduces construction and maintenance cost over traditional building methods. The ease of construction reduces the learning curve for the assembly process. Embedded utilities in the components further minimize construction time. The modular nature of the design system allows for rapid assembly, disassembly, and redeployment as needed. Components are specifically built to ship using standard shipping containers for optimal organization of components and transportation.
