A lower connector includes a lower connector hollow body, a pair of lower connector bosses coupled to the lower connector hollow body, and a pair of lower connector arms coupled to the lower connector bosses. A connector assembly includes an upper connector coupled to a lower connector and a gusset plate sandwiched between the upper and lower connectors.

Connectors for assembling off-the-shelf framework such as pipes and tubes. The connectors include parts that can have puzzle-shaped ends for locking the components together, and when connected, the connectors form various cavities that may include friction-inducing components disposed in the cavities to render the framework stationary. The cavities may be sized to accommodate different sizes of framework.

A connector includes a first joint member, a second joint member, and a fastener. The first joint member includes a first tubular outer wall at least partially enclosing a first outer cavity, and a first tubular inner wall at least partially enclosing a first inner cavity. The second joint member includes a second tubular outer wall at least partially enclosing a second outer cavity, and a second tubular inner wall at least partially enclosing a second inner cavity. The fastener extends through first and second openings of the first inner cavity, and through first and second openings of the second inner cavity to position the first joint member relative to the second joint member.

A bracket for supporting a plurality of vertically extending supports is provided. The bracket has an outer housing and an internal support. The internal support is receivable within the outer housing, and the outer housing and the internal support together define a plurality of channels. Each one of the plurality of channels is shaped and configured to receive a free end of a corresponding one of the plurality of vertically extending supports.

The invention comprises a scalable and foldable multipurpose frame structure configured with a generally flat-roof as a worksite and a peaked-roof as a recreational canopy, a cover retaining system and a ventilation system. The frame structure comprises a plurality of foldable wall trusses connecting a plurality of upright telescopic posts transversely forming a wall frame structure and a closed loop geometric footprint, a plurality of foldable roof trusses connecting a centrally disposed roof assembly to either the telescopic posts or the wall trusses transversely forming the roof. The cover retaining system comprises various spring clips for known-size frame members, and various clamps for unknown-size frame members, to secure roof and wall cover to the frame structure. The ventilation system comprises an enclosure that can utilize standard furnace air filters and existing air circulation devices. Multiple frame structures can be linked together to scale up space.

The present invention relates to an integrated bracket for fixing a sprinkler reducer, and more particularly, to an integrated bracket for fixing a sprinkler reducer, in which left and right portions of a bar-shaped steel frame structure for a sprinkler bracket are vertically bent, tightening/coupling parts are provided at two opposite ends of the steel frame structure, and a fixing unit having a new structure and serving as a middle bracket is integrated with a central portion of the steel frame structure, such that the single bar-shaped steel frame structure may perform a function of fixing the sprinkler reducer and coupling a ceiling steel frame.

A storage container includes: a frame defining a storage space, the frame including a plurality of lower poles extending in a first direction at a bottom of the storage container, a plurality of first side poles coupled to the plurality of lower poles and extending in a second direction crossing the first direction, a plurality of second side poles coupled to the plurality of lower poles and extending in the second direction, a plurality of second upper poles coupled to the plurality of first side poles and the plurality of second side poles, and a plurality of first upper poles coupled to the plurality of second upper poles and the plurality of first side poles; a base around the frame and defining an opening; a top attached to the base; and a support member attached to the frame and connected between adjacent ones of the plurality of first upper poles.

A batten fixing clip, comprising: a male connector comprising a batten interface portion for attachment to a batten, and a female connector interface portion for engaging a female connector; and a female connector comprising a support structure interface portion for attaching to a support structure and a male connector interface portion for engaging the male connector, the male connector interface portion including a retainer and a resilient clip comprising of an aperture, wherein the aperture receives at least part of the female connector interface portion and the clip biases the female connector interface portion against the retainer when in use.

A sign having a display section formed from two pliable sheets and a frame assembly having members joined by various connector pieces. The connector pieces may include couplers and corner pieces. The connector pieces may be used to construct the frame assembly. The connector pieces may also be used to stow the frame assembly when the sign is not in use or being packaged for shipment and also during shipment. For example, the connector pieces may cover the ends of frame assembly members to keep them organized and to keep the members from piercing packaging or other parts of the sign.

A connector assembly, which in one embodiment has an upper connector and in another embodiment has a lower connector. The assembly can have a gusset plate sandwiched between the upper and lower connectors. Also, disclosed is a hoistable connector assembly, a lifting frame assembly, a coupling system for modular frame units, a method for assembling a module unit using the connector assembly, and a modular frame unit and building having the connector assembly. Also, a system for coupling adjacent modular frame units for forming a modular building and a method for coupling modular frame units for forming a modular building are provided.
