An anchor rail for fixing fasteners includes a first rail part and a second rail part which are connected to one another and on each of which anchor webs are formed, wherein a channel-shaped receptacle for a head section of a fastening means is formed between a first wall of the first rail part and a second wall of the second rail part, and an inwardly projecting web is provided on the first wall and an inwardly projecting web is provided on the second wall, and the inwardly projecting webs overlap the channel-shaped receptacle at the edge side. An outwardly projecting support web projects at least in sections on the first wall and/or the second wall opposite the inwardly projecting web. A method for producing an anchor rail which can absorb particularly high forces includes forming the inwardly and outwardly projecting webs from strip-shaped blanks welded to the first and second rail parts.

A connector assembly, having an upper connector, a pin coupling the upper connector to a lower connector and a gusset plate sandwiched between the upper and lower connectors. Also, disclosed is a hoistable connector assembly, a lifting frame assembly, a coupling system for modular frame units, a method for assembling a module unit using the connector assembly, and a modular frame unit and building having the connector assembly.

A weldment support for holding a weldment plate in a precast concrete form is provided. The weldment support holds the weldment plate at a predetermined position so that the weldment plate is exposed on one side of the finished precast concrete panel. Weldment plates have one or more studs extending into the form to anchor the plate in the precast concrete panel. The weldment support has multiple adjustment features to secure the weldment support to different sizes of studs and to set the weldment plate at different positions within the form. In some embodiments, one adjustment feature is a plurality of deflectable fingers that engage the stud of the weldment plate, and another adjustment feature is a plurality of segments that can be broken off of the support to set the position of the weldment plate in the form.

A masonry veneer support assembly for mounting masonry veneer to supporting wall structure has a shelf angle, and first and second shelf angle mounting brackets. Each shelf angle mounting bracket has an upwardly extending back that mounts to the supporting wall structure, and a web extending forwardly away from the wall structure. The web has first and second shelf angle mounting seats formed therein. The first shelf angle mounting seat is upwardly spaced from the second shelf angle mounting seat. Hangers in the form of two-part separable brackets are provided to permit masonry veneer to be mounted underneath the shelf angle, thereby concealing it from view.

The invention provides a prefabricated volumetric construction module having connection mechanism for securing to other similar modules. A prefabricated volumetric construction module includes a self-supporting structure and pairs of corner castings arranged at least at the corners of the structure. During building construction, the modules are assembled and secured together using connection rods and interlocking plates to provide vertical securement between vertically adjoining modules and horizontal securement between horizontally adjoining modules.

A ceiling beam connector that permits the incorporation of ornamental panel designs such as triangles, parallelograms, and trapezoids into suspended ceilings. The connector has a faceplate attached to either two arms or a leg. The leg is attached to either the faceplate or an arm at an acute angle measured from an axis perpendicular to the faceplate. To maintain standard beam lengths and rout spacing at 2 foot, 3 foot, or 4 foot (61 cm, 91 cm, or 122 cm) beam spacing, the leg may project out at the following angles measured from the axis: about 14.0°, about 18.4°, about 26.6°, about 30.3°, about 45.0°, about 59.7°, about 63.4°, about 71.6°, or about 76.0°.

A foundation connector is formed with a foundation attachment section and a frame attachment section connected by a transition section at the central area of the foundation connector. The frame attachment section is attached to a frame member with fasteners and the foundation attachment section is attached to the foundation with anchors. The foundation attachment section has a curved foundation attachment base. The frame attachment section has a curved frame attachment base. A transition section is provided between the foundation attachment section and the frame attachment section that is curved.

Structural plates and methods of constructing arch-shaped structures using structural plates. Structural plates may include a combination of features including: an outer structural plate having adjacent circumferential apertures respectively spaced nominally greater than adjacent circumferential apertures of an inner structural plate; and the outer structural plate having nominally 5 enlarged or differently shaped circumferential apertures (as compared to circumferential apertures of the inner structural plate) such that the embodiment structural plates may be radiused to a variety of different radii while achieving desirable overlapping alignment of apertures along overlapping circumferential edges for receiving fasteners therein. Joiner plates may be provided for interconnecting structural plates along transverse edges in a non-overlapping arrangement, 10 thereby reducing the quantity of structural plate material that otherwise would be needed for a given circumferential length of the arch-shaped structure.
