A system and method for securing a roof truss to a load bearing wall is disclosed. A strap is attached to a roof truss at one end and extended to the top of a load-bearing wall. A buckle is placed over the strap to pinch the strap between the vertical and horizontal arms of the buckle. The end of the strap is wrapped back toward the vertical side of the roof truss and a flat plate is placed to pinch the free end of the strap between the buckle and the flat plate. Screws are placed through holes in the flat plate and corresponding holes in the buckle to attach the system to the top of the load-bearing wall. The system and method of the invention provides both horizontal (lateral) resistance and uplift resistance, thus resisting horizontal (lateral) forces while at the same time providing uplift resistance.

A frame using tubular columns and tubular rafters of generally rectangular cross section. Columns are arranged parallel, spaced apart, opposed pairs that are connected by bolted-on girts to form wall frames. Rafters are arranged parallel, spaced apart, opposed pairs that are connected by bolted-on purlins to form roof frames. Inwardly facing sides of columns and rafters have pluralities of castellated holes. Outwardly facing sides of columns and rafters have another plurality of castellated holes. All connections for braces and crane lifts are made in the inwardly facing sides of the columns and rafters. Joints have either a ridge plate or a haunch plates, each plate with two bolt holes that may be pivot holes and additional bolt holes for securing the plates. Base plates have two pairs of parallel vertical spaced-apart flanges, each pair fitting within and releasably attachable to a column. Pairs may be arranged parallel or perpendicular.

Described is a method and apparatus for constructing light-weight, modular structures using special openC beams as a top and a bottom frame. Each openC beam comprises a vertical web member, a horizontal top flange extending perpendicularly in a first direction from the vertical web member, a horizontal bottom flange extending perpendicularly in the first direction and substantially parallel with the horizontal top flange and a upper vertical tab extending substantially perpendicularly from a distal edge of the horizontal top flange away from the horizontal bottom flange. Vertical posts are installed in one or more cutouts in the horizontal top flange of each openC beam and a planar surface of each of the vertical posts rests against the horizontal top flange for added support.

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.

The present invention relates to a truss that allows the formation of an arc when connected with other trusses and that creates an optimal angle that generates a lower calculation effort in the structure.

The present invention also relates to an arched structure comprising a plurality of such trusses and to a shed comprising a plurality of arched structures.

This invention relates to prefabricated, lightweight, multi-component structural modular building panels and modular building systems. The said panels are framed with edge members that have a unique connecting shape, making them modular. The multi-component panel allows for design flexibility and the mass manufacturing of its components. Connectors serve as a link to assemble the panels together, and to connect them to corners, floors or foundations, roof panels and the roof apex member, and or other conventional construction elements. Connectors and members, all with unique connecting shapes, coupled with the said panels, create a structural wall, roof, similar structure or building system. Assembled panels and members incorporate the primary building structure and the building envelope. The assembled panels, members and other components of the building system, in part or whole, can be flat packed for easy transport and shipping, and can be assembled quickly and easily with semi-skilled labor.

A modular building section defining the roof and opposing walls of a modular clearspan building. The building section includes a roof portion extending in a longitudinal direction between opposite first and second ends, and a pair of first and second legs, each leg pivotally attached about a pivot axis to the roof portion proximate a roof portion end. Each of the first and second legs has a stowed position in which the leg generally extends in the longitudinal direction and is in superposition with the roof portion, and an expanded position in which the leg depends from the roof portion and generally extends perpendicularly to the longitudinal direction. The legs are moveable independently of each other from their respective stowed positions to their respective expanded positions under the influence of gravity during lifting of the roof portion. Also disclosed are methods for constructing a modular clearspan building.
