A purlin mounting system for use in a flat roof structure includes a purlin with a flat mounting wall and an upright wall extending perpendicularly from the mounting wall. First and second mounting shelves are attached to the upright wall and extend outwardly in opposite directions. Each mounting wall is positioned to receive an edge of a roof section thereon. The flat mounting wall and the upright wall define a vertical mounting channel extending from a lower surface of the flat mounting wall a distance less than the distance of the first and second mounting shelves from the mounting wall. A purlin positioning and mounting device is designed to be attached to a roof beam and includes a vertically extending support wall designed to extend upwardly from a supporting roof beam when attached to the supporting roof beam and to nest within the mounting channel.

A structure with integrated insulation. The structure with integrated insulation includes a steel frame. The steel frame includes a first support beam and a second support beam. The structure with integrated insulation also includes an assembly with integrated insulation. The assembly with integrated insulation includes a first building panel with integrated insulation, the first building panel with integrated insulation being attached to the first support beam on the first surface of the first building panel with integrated insulation. The assembly with integrated insulation also includes a second building panel with integrated insulation. The second building panel with integrated insulation 4 includes an indentation in the first surface configured to receive at least a portion of the first building panel with integrated insulation. The second building panel with integrated insulation being attached to the second support beam on the second surface of the second building panel with integrated insulation.

The present invention discloses steel framing members for use in load bearing solar applications to reduce the amount of steel used by providing structural shapes that allow for more bending and torsion strength which allows for greater spans between posts and rafters to reduce the number of posts, rafters and concrete used. The structural shapes further allow for the elimination of angle braces and the elimination or reduced use of sag rods, knee braces and the associated fasteners. Multiple fastener locations on the same structural member assist further in bending and torsion strengths and allow for lighter gauge materials to be used to conserve materials. Minimizing or eliminating the number of posts, rafters, concrete, angle braces, sag rods, knee braces and fasteners also reduces the amount of equipment and labor used. The labor and material savings helps make solar applications less expensive and provides a lower carbon footprint to make the possibility of using them more attainable.

A modular construction system in which a number of three dimensional construction elements are adjoined to form a modular wall, ceiling or floor assembly. In their pre-assembly condition, each three dimensional construction element is formed from a planar metallic sheet (10) sub-divided by fold lines (12a, 12b) into panels (14, 16, 18) defining a multi-panelled sheet. Each panel lies in a common plane and at least one of the panels is deformable along its fold lines out of said common plane to form an assembled three-dimensional construction element for adjoining to other three-dimensional construction elements. At least one panel is provided with an opening (14a, 16a) dimensioned to allow the passage of a reinforcement or stabilizing material through the assembled three-dimensional construction element.

The invention describes a girder profile made of stone material and tensile-resistant material, which is preferably made of CO2 in order to fix greenhouse gases. This is intended to replace steel girders and aluminum girders with sustainable building materials. The invention adopts the principle of dovetailing from timber construction and transfers this principle to the structure made of stone material and fiber material, in that the planes of the profile, which usually meet orthogonally, overlap geometrically with regard to the tension-stable material parts or at least meet in one cutting plane. Such materials made of mineral substances and fibrous materials are significantly lighter, more durable and more ecological than such carriers made of metallic materials.

Sub-girts usable in exterior wall system assemblies are disclosed that encompass ventilation and/or spark-arresting features and/or adhesive-receiving features. The sub-girts can comprise one or more flanges and chords that have ventilation holes and/or adhesive-receiving holes formed therein. The flanges and the chords of the sub-girts can form within the sub-girt and/or the exterior wall system assemblies one or more chambers through which air and moisture can travel and/or flame and spark be arrested.

A deck framing system includes a perimeter support member that has a joist support wall and a web wall extending perpendicularly from the joist support wall and an overhang wall extending perpendicularly from the web wall. First and second joist support brackets include a joist support portion and a pair of attachment wings, where each one of the pair of attachment wings contacting the web wall of the perimeter support member. First and second joists each include a deck support wall and a lower wall. The deck support walls of the first and second joists are disposed between the overhang wall and the joist support portions, and the lower walls are disposed between the joist support portions and the joist support wall.

A panelized system for structural decking systems. The panelized system has a plurality of joists operatively coupled together through one or more decking panels. In order to aid in resisting rollover (e.g., the joists rotating with respect to the decking panels and/or support members during installation) bracing members may be utilized. A bracing member may be operatively coupled to a joist (e.g., a lower chord of a joist, web, upper chord, or the like) and to the decking panel (e.g., location on the decking between two joists, such as the mid-point of decking between two joists, or the like). In this way, the joists may be supported directly to the decking instead of having to run cross-bracing (e.g., x-shaped, or the like) between each of the joists. Once the panelized system is assembled on the ground, the panelized system may be lifted into place and assembled to a building.

There is described a method of manufacturing a dome (2), the method comprising: providing a plurality of beams (6, 106, 206, 306), each of the plurality of beams (6, 106, 206, 306) comprising one or more slots (16, 22); and engaging at least one of the slots (16, 22) of each of the plurality of beams (6, 106, 206, 306) with a slot (16, 22) of the one or more slots (16, 22) of another of the plurality of beams (6, 106, 206, 306) so as to form at least part of the dome (2). There is also described a dome (2) manufactured in accordance with the method.
