The collapsible shelter includes a truss and canopy framework that permits a flexible, collapsible canopy to be moved between a raised position and a lowered position. The collapsible shelter includes at least three legs supporting flexible poles removably mounted to the tops of the legs and forming the framework of the canopy. X-shaped truss pairs of link members are connected to each of the legs on each side of the shelter between adjacent legs.

A frame tent system having a plurality of upright columns, a plurality of eave members, and a plurality of rafters. The plurality of members are inter-connected by a system of novel eave weldments. The eave weldment is preferably a four-way connector unit interconnecting the frame members of the tent system at major points of connection to form the frame tent system. The eave weldment is formed of a weldment plate and an insert tube disposed perpendicular to the weldment plate. The frame members of the tent system each include a channel for releasably receiving ends of the eave weldment. In particular, the channel disposed in the rafter receives a first end of the weldment plate; the channel disposed in the upright column receives a second end of the weldment plate; the channel disposed in the eave members receive an end of the insert tube thereby forming the frame tent system.

A connection apparatus includes a frame-side member securable to a steel structural frame, a brace-side member securable to a seismic brace, and a coupling element that secures frame-side and brace-side members to each other. By way of example, the connection element may provide a hinge-type connection, which substantially isolates a seismic brace from nonaxial loads. As another example, the connection element may be a ball-and-socket type connection, which substantially isolates a seismic brace from nonaxial loads and absorbs any shear and moment applied thereto when the seismic brace drifts out of an intended plane of the steel structural frame. The connection element may also include a collar to stabilize the brace-side member and prevent shears and moments from causing the same to buckle in an unintended direction. Methods of installing and using the connection apparatus are also disclosed.
摘要:
A frame joining structure for electrical and electronic equipment housing cabinets, in which ends of frames are simplified in shape to dispense with complex cutting and which possesses excellent strength and waterproof property. Ends of outer side surfaces (4) of three mutually orthogonal frames (1a, 1b, 1c), which constitute a framework of a cabinet, are cut at two planes of ±45° relative to a plane defined by other two frames to be point-shaped. These ends are joined together directly or through a corner member (20) having the same configuration as that of the ends to constitute a firm corner portion.

The collapsible shelter includes a truss and a canopy framework that provides a flexible, collapsible canopy that is capable of flexing and moving, in whole or in part, between a raised position and lower positions having a reduced profile from the raised position. The collapsible shelter includes at least three legs supporting a flexible framework mounted to the tops of the legs and forming the framework of the canopy. Truss pairs of link members are connected to each of the legs on each side of the shelter between adjacent legs.
摘要:
A connection assembly for connecting parts of a multi-component product comprising a post having two releasably interlocking sides and an extension member. A slot provided in the exterior sidewall of the post at the juncture of the interlocking sides is configured to mate with the extension member. The extension member may be engaged with the slot when the two sides of the post are in a separated unlocked position. The two sides may then be placed in an interlocking position so as to fixedly connect the extension member therebetween.

A linear cold connection with connecting places contains a first and a second structural component to join first and second construction elements of a frame for road or rail bound vehicles. First construction elements are attached to the first structural component and second construction elements are attached to the second structural component. The first and second structural components are joined together via a pair of first and second joint faces. The joint faces form a length of arc of a circular cylinder with a common circular-cylinder axis. The first structural element is joined to the second structural element via a bolt-type connection penetrating openings in the first and second joint faces. The diameters of the openings transverse to the circular-cylinder axis are larger than the diameters of the bolts where they penetrate the openings with the result that, when the bolt-type connection is loose, both structural components can be displaced with respect to each other by relative movement of the first and second joint faces transverse to the circular-cylinder axis and with that accommodate tolerances.
摘要:
A prefabricated building component, e.g. for incorporation in a wall, a floor, a roof or another building component, comprises a frame formed by lengths of lumber with heat insulating foam material provided in spaces between the lumber so as to form a heating insulating barrier. To reinforce the frame against racking forces, a reinforcement sheet of fiber reinforced composite material is provided on the barrier and the lumber at least one side of the frame.

A board to board coupling structure coupled between at least two panel assemblies, the board to board coupling structure including a tubular shaft, two locating plates respectively mounted in a longitudinal groove at the tubular shaft, two inner socket assemblies respectively mounted on the tubular shaft, two end caps respectively mounted on the tubular shaft, two outer sockets, a plurality of hook plates, and a plurality of plug plates. The hook plates are fixed to the at least two panel assemblies, each having a hooked portion respectively hooked on a top notch at an outer race at one inner socket and a notch at an upright flange at one outer socket. The plug plates are fixed to the at least two panel assemblies, each having a plug portion inserted in between the socket body and outer race at one inner socket and engaged into the notch at the upright flange at one outer socket. The end caps each have toothed blocks inserted in gaps between threads at the socket body of each inner socket and then respectively forced into engagement with the threads at the socket body of each inner socket.
