A composite structural member for a building structure comprises a first elongate portion having a first end region and a second end region and a second elongate portion having a first end region and a second end region. The second end region of the first elongate portion is connected to the first end region of the second elongate portion so that the composite structural member provided thereby is substantially longer than either of the first and second elongate portions. The first elongate portion may comprise a first member suited for resisting high magnitude forces and the second elongate portion may be a second member, less well suited for resisting high forces but having lower cost per unit length. The composite structural member may be a rafter, especially a rafter of a portal frame.

An interface for a structural column includes a female end section that includes at least one first sidewall that extends from a first end along a longitudinal direction and defines a first cavity. An interior surface of the at least one first sidewall tapers transversely outwardly along the female end section towards the first end. The interface also includes a male end section that includes at least one second sidewall that extends from a second end along the longitudinal direction and defines a second cavity. The at least one second sidewall is configured to be received within, and oriented in substantially face-to-face adjacent relationship with, the at least one first sidewall. Each of the female end section and the male end section is a respective unitary casting.

The present invention discloses the components and kit for technical construction method of sturdy and permanent connection up to six beam components perpendicularly, while none of the nodal joint structure protrudes outside the open channel(s) of the beam component(s). The method is user friendly during assembling.

The present invention relates to a building construction having a smaller aperture by extending the aperture top side edges referred to as protrusions and where the protrusions and the aperture bottom edges secure metal framing members from vertical movement and the aperture side edge and hole notches that secure the metal framing members from vertical and horizontal movement. The metal framing members have different shapes and notches that overlap other metal framing member that engage the metal support members to reduce or eliminate vertical and horizontal movement between the metal framing members.

A swaged interface includes a male element that includes a male cavity defined by at least one male sidewall, and a plurality of first openings defined in the at least one male sidewall. The swaged interface also includes a female element that includes a female cavity defined by at least one female sidewall, and a plurality of second openings defined in the at least one female sidewall. The female element has an inner cross section sized to receive the male element such that each of the first openings is aligned with a respective one of the second openings. The inner cross section is formed by swaging.

A building system for building modular structures, based on the use of universal structural elements, and their universal fasteners, where all elements are of opposite ends or bipolar elements, where each end refers to the distance from the intersection point of two connectors to the center of the holes at the time of assembly.

A tubular beam with mechanically fastened end plates preferably includes a tubular member and at least one end plate. At least one cross plate may be secured within the tubular member with fasteners to strengthen thereof. The tubular member may have any suitable cross section including, square, rectangular, hexagonal, triangular or the like. A plurality of hand access openings, a plurality of beam fastening holes and a plurality of fastener holes are formed through a side wall of the tubular member. The end plate is attached to an end of the tubular beam with a plurality of fasteners. A fastener gusset may be formed in inside corners of the tubular member to accommodate a blind fastener hole for attaching the at least one end plate. Each end plate preferably includes a hand access opening, a plurality of plate fastening holes, and a plurality of blind fastener holes and/or fastener holes.

An assembly column-beam connection component includes a vertically-oriented connecting body for connecting to columns and a horizontally-oriented connecting body for connecting to beams. One end of the horizontally-oriented connecting body is connected to the vertically-oriented connecting body. The vertically-oriented connecting body includes sequentially arranged front sidewall, left sidewall, rear sidewall, and right sidewall. Each of these sidewalls features concave portions extending along the vertically-oriented connecting body's length in the vertical direction. The concave portions on the left sidewall and rear sidewall are positioned near the junction of the left sidewall and rear sidewall, while those on the front sidewall and right sidewall are situated at their respective centers. Multiple installation through-holes for connecting to columns are provided on the various sidewalls of at least one end of the vertically-oriented connecting body.
