A splice having a main body and one or more protrusions extending from the main body. The one or more protrusions can be operable to interfere with a rail when the main body is installed into an opening of the rail. The one or more protrusions may be operable to cut into a coating of the rail and form an electrical connection between the rail and the main body.

A method including placing on a surface a first beam having a first end with a first clevis component opposing a second clevis component. A second beam, including a second end having a third clevis component opposing a fourth clevis component, is placed adjacent the first end on the surface. The first clevis component is connected to the third clevis component. A lifter is connected to the first end and the second end, which are lifted simultaneously from the surface while rotating the first beam and the second beam about the connector until the second clevis component engages the fourth clevis component. Connection between the second clevis component and the fourth clevis component then may be completed.

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.

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.

A construction system for a module of a dwelling the main elements of which are made of plastic material includes a set of hollow profiled beams (1, 1) of elongate rectilinear shape of type 1 and of type 2. The beams (1, 1) include at each end (5, 5) a transverse passage opening (6, 6). The transverse passage opening (6) of a beam (1) of type 1 comes to be nested with the transverse passage opening (6) of a beam (1) of type 2 when the two beams (1, 1) are assembled end to end at a right angle leaving a passage opening (6, 6) between the two ends (5, 5) of the beams (1, 1). Two beams (1) of type 1 can be assembled with two beams (1) of type 2 to form a rectangular frame. The system further includes a set of corner assembly elements (2, 2), each assembly element (2, 2) including a body intended to pass through the transverse passage opening (6, 6) of the beams (1, 1) of type 1 and 2. The system also includes a set of plates (3) that can be assembled between two beams (1) of type 1 when assembled or two beams (1) of type 2 when assembled to form a rectangular frame, and a set of posts (11) of hollow rectangular section the hollow ends of which come to be nested over a corner assembly element (2, 2) of a rectangular frame formed of beams (1, 1) of type 1 and of type 2 so as to form a three-dimensional framework. The posts (11) include longitudinal rails or grooves (8) on two adjacent surfaces to receive other plates (3) between the posts (11) during assembly. Each hollow profile beam (1, 1) including along an upper surface spaced rails or grooves (8) intended to receive said other plates (3).

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.
