Methods and apparatuses may include a stiffened beam assembly including a structural beam portion having a web and upper and lower flanges, and at least one continuous stiffening member extending back and forth between the upper and lower flanges on one side of the web, forming one or more trusses or other reinforcing structures. The beam portion and/or the stiffening member(s) may comprise formed sheet metal. The stiffening member(s) may be mechanically attached to the beam portion.

The present invention is directed to a framing member for use in a steel framed flooring structure. The framing member has a U-shaped rectangular cross section with two parallel spaced apart flanges and a central web bridging the flanges and connected to one edge of each of the flanges. The central web has an extension on each end thereof, the extension extending beyond the flanges a distance of at least half the width of the flange.

The present invention provides a prefabricated floor panel system used in stay in place formwork for pouring concrete floors. The prefabricated floor panel system includes a top and has walls depending downwardly at an upper lateral edge of the wall from each outermost lateral edge of the top, a lower lateral edge of each wall having a ledge extending outwardly away from the top. A first ledge of one prefabricated floor panel system is capable of overlying another ledge of an adjacent prefabricated floor panel system to allow for the one prefabricated floor panel system to be joined to the adjacent prefabricated floor panel system to form a channel. The first ledge of the prefabricated floor panel system is provided with a reinforcing bar spaced away from the wall and the first ledge of the prefabricated floor panel system, the reinforcing bar being supported by a plurality of a reinforcing bar chairs spaced along the length of the prefabricated panel system, the reinforcing bar chairs being attached to the first ledge or wall such that there are no significant interfering structures projecting from a lower surface of the first ledge. The other ledge of the prefabricated floor panel system is free of interfering structures above the ledge to allow the first ledge of one prefabricated floor panel system to overlie the other ledge of an adjacent prefabricated floor panel system to allow for the one prefabricated floor panel system to be joined to the adjacent prefabricated floor panel system to form a channel.

The present technology relates to beams having a cross section defining a plurality of channels and assemblies comprising the beams. The beams can be used to form a beam assembly that is installed inside the truck bed of a pick-up truck. A ladder loader and a solar panel assembly can be pivotably secured to the beam assembly along either the driver side wall or the passenger side wall of the truck bed.

An elongated structural ceiling grid member including an open-ended upper portion, an open-ended lower portion, and first and second flanges. The open-ended upper section is formed by a floor and a first set of second parallel and spaced sidewalls extending from and substantially perpendicular to the floor. The open-ended upper portion has an opening opposite the floor and defined by the first and second parallel and spaced sidewalls. The open-ended lower portion is formed by a ceiling and a second set of parallel and spaced sidewalls that extend from and are substantially perpendicular to the ceiling. The open-ended lower portion has a second opening opposite the ceiling and defined by the third and fourth parallel and spaced sidewalls. The first flange is attached to and extends perpendicular to the third parallel and spaced sidewall and the second flange is attached to and extends perpendicular to the fourth parallel and spaced sidewall.

An elongate profile (1) having a first portion (2) and a second portion (3), the first and second portions (2, 3) being joined together at a first joining portion (JP1), the first and second portions (2, 3) being non collinear, the joining portion (JP1) comprising an array of raised or rebated formations (10a), each formation extending across the joining portion (JP1) in a direction which is non-parallel to the principal axis of the profile and flat lands being provided between successive formations in an array (10A) and the pitch (P) between successive formations in an array being from 2 to 20 times, for example from 5 to 15 times, the thickness (G) of the flatlands.

A monolithic corner encapsulates one or more panels while maintaining structural integrity and maintain hygienic properties. The corner may securely receive one or more panels and provide flexibility to easily adjust the one or more panels. The corner may simplify installation and an ability to adjust connected panels without compromising safety, installation time, and sterility.

The invention proposes a system for constructing a module of a building, including core construction elements (1) that are surrounded by the surrounding construction elements (2A, 2B). The core construction elements (1) each include, in section, a cross including two main arms (6) of equal length which intersect at mid-length at right angle. Each core construction element (1) has a plane of symmetry about the axes of the arms. The main arms (6) of the cross terminate, at the ends thereof, with transverse portions (7). Each surrounding construction element (2A, 2B) is composed of four partial surrounding parts (2A, 2B, 2A′, 2B′) of a generally triangular shape which are assembled around a core element (1). Construction elements forming junction parts (4A, 4B) allow assembling panels (4A, 4B) to form a module of a building in the form of a rectangular parallelepiped volume comprising four corners.

The invention relates to a structural beam for use in a building, the structural beam comprising a first end, a second end and a longitudinal axis extending therebetween; at least two spaced apart wall members each wall member extending parallel with the longitudinal axis, abase member spanning between the at least two spaced apart wall members, wherein the base member and each wall member cooperate to form a trough for receiving cement, wherein each wall member includes: a first ledge extending outwardly away from the trough and; a second ledge extending outwardly away from the trough; wherein the first ledge and second ledge cooperate to form a channel dimensioned for receiving a part of an insulation member.

A splice joint of a main girder of a crane, the main girder including at least two longitudinal main girder parts to be connected to each other by their ends and each having a central web which includes at least one web plate, longitudinal upper and lower flanges, the lower flange protruding from the central web to both sides thereof. The splice joint includes a plate-like tongue-and-groove joint, the tongue-and-groove joint including a tongue fixed to the central web of a main girder part, and a groove fixed to the central web of a second main girder part; and a lower flange joint receiving the bending forces of the splice joint. The tongue-and-groove joints are arranged reversed in relation to each other, and the location of the tongues and grooves on opposite sides of the web is reverse in relation to each other.
