A framing assembly has at least one rafter vent assembly having a connecting member with a plurality of vent tubes for providing supplemental ventilation and additional structural support to a frame of a building structure. The at least one rafter vent assembly may be an interior rafter vent assembly or an exterior rafter vent assembly. The interior rafter vent assembly has at least one brace member and a connecting member, with the connecting member having a connecting plate, two end plates, and the plurality of vent tubes. The exterior rafter vent assembly has the connecting member that has a connecting plate and the plurality of vent tubes. The framing assembly also preferably has a plurality of modified structural insulated panels (SIPs) and modified rafter splines.

A ridge is directly supported by a ridge supporting post that is erected on a floor plane of a floor right below a gable roof to provide a stable building frame having a pentagon shape in front view and furthermore to realize a beamless space where no lower chord member such as a roof beam extends above the floor right below the gable roof. Also, a tall window extending continuously toward the vicinity of the ridge is provided between the ridge supporting post of a gable end wall and each of gable end side sub-pillars erected on both sides of the ridge supporting post. Thus, a living space gives a feeling of spaciousness and openness in spite of a compact appearance of a building.

A light steel roof truss with a structure of a double continuous beam includes structural beams (1) and structural columns (2). The structural beam (1) consists of a pair of continuous beams, and the structural column (2) is located between the two continuous beams through locating holes (4). Thereby the stability of a support structure of the roof truss is increased, and the supporting members of the roof truss can be connected conveniently.

This invention provides fall protection systems, in metal building construction, and methods of installing such systems. A given such system comprises a suspension fabric, supported by a grid-work of longitudinal and lateral support bands. The distance of the safety band from the rafter corresponds to about 40 percent to about 75 percent of the diameter of the bag. Thus for a 30-inch diameter bag, the distance between the edge of the rafter and the middle of the safety band is about 12 inches to about 23 inches. The safety band protects the suspension fabric from being cut by the near edge of the rafter when a falling object impacts the fall protection system near the edge of the rafter.

Load support structures for mounting a load atop a raised rib metal panel roof make use of relatively small, inexpensive, and easy-to-make adapter plugs as interfaces between the raised ribs and one or more component pieces or members of the load support structure, such as an upper diverter or a lower closure member. The adapter plug has an inner surface and an outer surface, the inner surface having an inner profile substantially matching or conforming to some or all of the profile of a particular style of rib profile. The outer surface of the adapter plug has a standardized shape, some or all of which is made to conform to an upper diverter, lower closure, and/or other component member of the load support structure.

This invention provides fall protection systems comprising a suspension fabric, supported by a grid-work of longitudinal and lateral bands, in metal building construction. The fall protection system uses the combination of relatively softer banding, a safety band spaced a particular distance from each rafter, and safety clips to attach the safety bands to the intermediate purlins, thus to distribute the force of impact of a load, falling close to a rafter, to better absorb and dissipate the force of the impact, including distributing the impact of the falling load over a greater area of the roof structure. The invention further provides methods of making elements of such systems, methods of installing elements of such systems, and buildings embodying such systems.

A mobile building constructed on a trailer, comprising: a wheeled trailer upon which the building is built, a floor and a plurality of walls secured to the trailer; and a roof structure, wherein external sides of the walls are braced with sheeting secured to the walls, the sheeting extending from a base of the building and securing to the roof structure.

The invention discloses a device for real-time monitoring and correcting the displacement of indoor microform model measuring equipment, comprising a measuring equipment, a sensing device, and a adjusting device that are installed on a truss; the outside of the truss is provided with a horizontal and a vertical base point; the sensing device and the adjusting device both take the horizontal and vertical base points as benchmarks, and are both connected to a controller; the adjusting device is connected to the measuring equipment, which can drive the measuring equipment to fine-tune on the truss. The invention further discloses a real-time monitoring and correcting method using the device. The invention is simple in structure, convenient to use, and easy to install. Since an automatic adjusting device is used, the adjustment value can be accurate to 0.01 mm, making the data obtained from the indoor model observation test more accurate and reliable.

Modular building methods and systems using precision machined modular panels. Standard modular panels are used for constructing walls, floor, and roof, with transitions from wall to roof and wall to floor provided by special transition panels. The standard panels include a channel formed configured to receive a flange of a C-channel member. The present method progresses by installation of a foam panel (or stack or row of such panels), followed by installation of a C-channel member, with the flange of such member engaged in the panels, followed by installation of an adjacent row or stack of panels, before installation of the next, adjacent C-channel member. Such alternating placement of panels and frame members eliminates the need for a tape measure, the need for any independent frame for the building, and ensures the walls, floor, and roof are square and plumb, as the precision machined panels ensure these requirements are met.

The present disclosure provides systems, apparatuses, and methods relating to roof construction. In some embodiments, a roof panel system may include a prefabricated horizontal building frame and a prefabricated roof panel structure. The horizontal building frame component may include a plate having a first aperture. The prefabricated roof panel structure may include two parallel lateral structural members and two parallel transverse structural members, one of the transverse structural members having a second aperture. The system may further include a fastener assembly connecting the horizontal building frame component to the roof panel structure through the first and second apertures.
