A rotary joint includes a socket rod having a socket rod flange with a basically spheroid concave bearing surface at a first end, a housing nut encircling the socket rod and having a threaded wrenching head, and a ball rod having a basically spheroid convex bearing surface and threaded side walls around the bearing surface. A diameter of the threaded side walls of the ball rod corresponds to a diameter of the threaded wrenching head of the housing nut. First guiding tracks are on the concave bearing surface oriented into a first swivelling direction, the socket rod being swivable to the ball rod along the first guiding tracks into the first swivelling direction. Second guiding tracks are on the convex bearing surface and oriented into a second swivelling direction, the socket rod being swivellable to the ball rod along the second guiding tracks into the second swivelling direction.

A corner fitting includes a sleeve body having a hollow inner space and configured to coaxially fit over a pipe member of a predetermined size. An edge of the sleeve body at a second distal end has a corner cut portion, a protruding tab, and two recesses, the protruding tab being diametrically opposed to the corner cut portion in the radial direction of the sleeve body, and the recesses being diametrically opposed to each other in the radial direction of the sleeve body. The corner cut portion is configured and shaped such that the sleeve body fits together with an identical sleeve body on the pipe member of the predetermined size with the corner cut portions of the two sleeve bodies contacting each other and with the pipe being nested between the protruding tabs of the second distal ends of the two sleeve bodies.

The present Stacked Wall Truss Construction and its use in multi-story buildings makes use of prefabricated modular wall elements (100) that are interconnected in three dimensions to enable the rapid completion of building construction with improved quality of construction over that found in traditional multi-story building construction. The resultant building is a structural steel frame without the use of stacking columns. Vierendeel trusses (100) with vertical members (101-105) of tube steel are used, thereby the construction process becomes stacking trusses fit up as complete walls, not erecting columns. An inner Mating Member (131-135) enables each truss to be near perfectly positioned on top of the installed truss below.

The present Stacked Wall Truss Construction and its use in multi-story buildings makes use of prefabricated modular wall elements (100) that are interconnected in three dimensions to enable the rapid completion of building construction with improved quality of construction over that found in traditional multi-story building construction. The walls are created with stacking modular elements to form a vertically continuous structure, and Floor Modules (161,162) are supported by a Floor Shelf (141-144) at predetermined elevations to provide a solid surface on top of which a Topping Slab (1031,1032) of concrete is poured which fills the space between the Floor Module and the Wall Trusses to create an integral structure.

A node for interconnecting frame members of a frame, the node including a single piece node body. A plurality of cup-shaped node connectors are disposed on the node body. Each of the plurality of node connectors include a closed end attached to the node body and an open end opposite the closed end and extending away from the node body. A sidewall extends between and connects the closed end to the open end. A tenon is formed on the open end. The tenon is shaped and sized to fit within a frame member. A transition is formed between the sidewall and the tenon defining a peripheral, radially outwardly facing groove in cooperation with the frame member, the groove shaped and sized to receive a weld.

Provided herein is an assembly for carrying or supporting a load. The assembly comprises a plurality of members connectable in an assembled arrangement for carrying or supporting the load. Each member comprises a first end and a second end, at least one of the first end and the second end has a pair of connecting members comprising two lugs that each has defined therein two holes. The lugs are configured for alignment with a corresponding pair of lugs formed on another member in the assembly. Fasteners extend through the holes formed in the lugs when the holes are aligned. Further provided are members for use in the assembly and connector elements for attaching two or more members in the assembly.

The disclosed technology includes a tripod reinforcement beam for reinforcing a tripod grillage of a transmission tower. The tripod reinforcement beam may include top and bottom faces that are substantially planar surfaces, a rear face disposed substantially perpendicularly between a rear edge of the top face and a rear edge of the bottom face, and a front face disposed between a front edge of the top face and a front edge of the bottom face. The rear face may include first and second substantially planar rear face portions and an angled rear face portion. The front face may be include first and second substantially planar front face portions that are oriented parallel to the first and second substantially planar rear face portions, respectively.
