In carrying out a loft conversion some way has to be found of reinforcing the triangular timber roof trusses so that the internal bracing can be removed, to make the space. In the invention this is done by fixing C-sections to the outline of the triangular trusses, preferably sandwiching the timber frame. For the C-sections to overlap at the corners, part of one flange, e.g., the upper flange of the horizontal beam, is removed, and then the beams are bolted onto the frame. The process can be carried out with minimal disruption to the roof as no transverse (longitudinal) reinforcement is needed. A dormer process can also be included, making use of a versatile reinforcement plate.

An improved greenhouse structure having sides and a roof to define at least a partially enclosed space, with an interior ceiling section and the interior ceiling section being at least substantially transparent. An air channel is formed between the roof and the interior ceiling section with an air input device in fluid communication with the air channel and the interior ceiling section has one or more openings through it to allow air in the air channel to pass through and into the enclosed growing space to provide a top-down air conditioned effect.

A building earthquake resistance structure includes an integrally connected roof support frame, used for supporting a roof of a building independently from walls of the building; a plurality of support columns, fixedly connected to the roof support frame; an annular trench, arranged in the ground around the building; an annular damping came, arranged within the annular trench, lower ends of the support columns being fixedly connected to the annular damping frame; a plurality of dampers, arranged between a bottom portion of the annular trench and the annular damping frame. An earthquake resistance method for the building earthquake resistance structure prevents damage caused by the roof collapsing during an earthquake by supporting the roof of the existing building in the ground via the support columns. The building earthquake resistance structure is easy to construct and suitable for transforming traditional old buildings.

A rafter reinforcement bracket apparatus for securing rafters to strengthen a wood frame roof includes a bendable strap configured to conform to a rafter bottom side of a pair of opposing rafters and a beam between the pair of rafters. A left and right bracket are coupled to a strap top side adjacent a strap front edge and a strap back edge, respectively. Each has a perpendicular portion extending perpendicularly from the strap and an upper portion extending perpendicularly from the perpendicular portion and lying in a plane parallel to a plane of the strap. Each of the strap, the left bracket, and the right bracket has a plurality of mounting holes extending therethrough. Each of the mounting holes is configured to receive a fastener to fix the apparatus to the pair of opposing rafters and the beam.

A portable windbreak shelter assembly provides a combination shelter and windbreak which can be moved to a desired position using conventional vehicles typically available on a farm includes a shelter frame having a front, a back, a bottom face, a first lateral side face, and a second lateral side face. The first lateral side face and the second lateral side face extend upwardly from respective opposite edges of the bottom face and meet to define an apex of the shelter frame extending between the front and the back. A covering is coupled to the shelter frame wherein the covering and the shelter frame inhibit wind from passing through the shelter frame to define a sheltered interior space. The shelter frame is movable using conventional farm equipment.

Agricultural barns, warehouses, and methods for construction including a floor, walls that include foam wall panels, a wainscot of impact resistant panels at a lower portion of the wall, and a ceiling formed from foam roof panels integrated into the roof truss assembly. Once the floor, walls, and ceiling are assembled, walls and ceiling can be coated over with an abrasion resistant, impact resistant polymeric coating (e.g., akin to a truck-bed liner), tying these structures together in a seamless shell that provides sufficient elasticity to accommodate typical expansion/contraction due to daily and seasonal heating/cooling, humidity changes, etc. The sealed interior envelope allows the interior surfaces to easily be pressure washed daily, or whenever else needed. Such construction is particularly well suited to an agricultural barn or warehouse, where cattle or forklifts may run into the lower portion of the walls, and pressure washing may be a daily need.

A roof system and related methods for installing the roof system. The roof system includes a roof diaphragm including a nail board and an insulating panel connected to the nail board, wherein the insulating panel is adapted to be positioned between the nail board and a roof frame so that the insulating panel engages the roof frame. In several exemplary embodiments, the nail board comprises one or both of: oriented strand board (OSB) and plywood. In several exemplary embodiments, the insulating panel comprises one or both of: a closed-cell rigid polyisocyanurate (polyiso) foam core and a polystyrene foam core. In several exemplary embodiments, the roof system further includes a plurality of nail board fasteners connecting the roof diaphragm to the roof frame, the nail board fasteners each extending through the nail board, through the insulating panel, and into the roof frame to a depth.

A roof attachment system and methods of using same during the installation, maintenance, or repair of a roof on a commercial or residential building structure. The roof attachment system and the related methods of using and implementing the system include, among other things, an anchor or internal support assembly, and a hook or securement assembly. The roof attachment system enables the installer to utilize at least one internal support assembly, or at least one internal support assembly and the securement assembly to install the roof, depending upon the installation stage of the roof. Upon completion of the installation process, the roof includes multiple concealed internal support assemblies that provide multiple anchor points that are spaced an appreciable distance apart along the ridgeline of the roof. When the roof requires maintenance or repair, the securement assembly can be removably coupled to a specific internal support assembly to facilitate the maintenance or repair by a technician while also reducing the chances that the technician experiences a fall from the roof.
