Prefabricated building

Abstract

A building constructed utilizing prefabricated wall frame structures, prefabricated roof truss structures and prefabricated purlin structures. In constructing the walls of the building, at least portions of the walls are constructed utilizing prefabricated braced frame structures. These braced frame structures can be interspersed with unbraced frame structures. Each of the braced frame structures has a plurality of lateral wooden frame members that interconnect two longitudinal wooden frame members and a built-in wooden frame cross-bracing member that extends in between the lateral wooden members. The wooden members of each of the frame structures are interconnected by metal connector plates. At least several of the purlin structures that are attached on top of the roof trusses have built-in cross-bracing. Each of the prefabricated braced purlin structures has a plurality of lateral wooden purlin members interconnecting two longitudinal wooden purlin members and a built-in wooden purlin cross-brace member extending between the lateral wooden purlin member. A plurality of metal connector plates interconnect the wooden members of the purlin structure. Each of the prefabricated roof truss structures is provided with at least a knee brace. This knee brace extends out from said roof truss structure in a V-shape formation for attachment to a longitudinal support column in such a manner as to distribute the forces created in the roof and purlin structure into the columns and truss joints, where the knee braces are connected to the columns.
