The truss bracket 100 (hereinafter invention) comprises a first side plate 200, a second side plate 210, and one or more web plates 220. The first side plate 200 may be coupled to the second side plate 210 by the one or more web plates 220 such that the first side plate 200 is parallel to the second side plate 210. The invention 100 may join two or more coplanar timber elements 900 at a joint of a roofing truss such that the two or more coplanar timber elements 900 may be retained in a predefined orientation. The predefined orientation may vary based upon the position of the joint on the roofing truss. The invention 100 may be operable to align the two or more coplanar timber elements 900, to limit insertion distance of an individual timber element selected from the two or more coplanar timber elements 900, to establish a pitch of a roof made from the roofing trusses, to hide an end face of one or more of the individual timber elements, or combinations thereof. As a non-limiting example, the roofing truss may be a rigid structure constructed by arranging the two or more coplanar timber elements 900 into an open framework while the two or more coplanar timber elements 900 are lying in a horizontal orientation. The two or more coplanar timber elements 900 may be coupled using embodiments of the invention 100. The roofing truss may then be rotated to a vertical orientation for installation on a building. The roofing truss may be replicated multiple times and used to provide distributed support for the roof. The invention 100 may aid in the rapid construction of a plurality of the roofing trusses where each of the roofing trusses requires joining of the two or more coplanar timber elements 900 in a consistent, reproducible manner.
Throughout this document, reference directions may be stated in terms of the roofing truss being in a vertical orientation as the roofing truss would be when installed on the roof. Front may refer to the side of the roofing truss corresponding to the positions of the first side plates 200 of the brackets and rear may refer to the side of the roofing truss corresponding to the positions of the second side plates 210 of the brackets. Left and right may refer to the viewer's left and right when standing in front of the roofing truss and facing the roofing truss. The top and bottom of the roofing truss are the upper and lower boundaries of the roofing truss as installed, respectively.
The various faces of the individual timber element may be referred as a front face, a rear face, end faces, and side faces. Specifically, the face of the individual timber element that contacts the first side plate 200 may be referred to as the front face of the individual timber element. The face of the individual timber element that contacts the second side plate 210 may be referred to as the rear face of the individual timber element. The smallest faces of the individual timber element may be referred to as the end faces of the individual timber element. The two remaining faces of the individual timber element that are not the front face, the rear face, or the end faces may be referred to as the side faces of the individual timber element.
The first side plate 200 may be a rigid plate that couples to the front faces of the two or more coplanar timber elements 900. The second side plate 210 may be a rigid plate that couples to the rear faces of the two or more coplanar timber elements 900. In some embodiments, the first side plate 200 and the second side plate 210 may be identical in size and shape. In some embodiments, the invention 100 may be operable to retain at least two of the two or more coplanar timer elements 900 to form an oblique angle between the at least two of the two or more coplanar timber elements 900.
The first side plate 200 may comprise a first plurality of fastener apertures 202. The second side plate 210 may comprise a second plurality of fastener apertures 212. The first side plate 200 and the second side plate 210 may couple to the two or more coplanar timber elements 900 using a plurality of fasteners 940 that pass through the first plurality of fastener apertures 202 and the second plurality of fastener apertures 212, respectively. As non-limiting examples, the plurality of fasteners 940 may comprise bolts, nuts, lock washers, flat washers, screws, nails, or combinations thereof.
In some embodiments, a one-to-one correspondence may exist between the positions of the first plurality of fastener apertures 202 on the first side plate 200 and the positions of the second plurality of fastener apertures 212 on the second side plate 210 such that a path may exist for an individual fastener to pass through one of the first plurality of fastener apertures 202, through one of the two or more coplanar timber elements 900, and through one of the second plurality of fastener apertures 212. As a non-limiting example, the one-to-one correspondence may exist between the first plurality of fastener apertures 202 and the second plurality of fastener apertures 212 such that an individual bolt may pass through one of the first plurality of fastener apertures 202, through one of the two or more coplanar timber elements 900, and through one of the second plurality of fastener apertures 212. An individual nut may then couple to the individual bolt to retain the individual bolt.
The one or more web plates 220 may couple to both the first side plate 200 and the second side plate 210 such that the one or more web plates 220 may establish a spacing between the first side plate 200 and the second side plate 210. An individual web plate selected from the one or more web plates 220 may be a rigid plate that couples to the first side plate 200 and the second side plate 210 along opposing edges of the individual web plate. As a non-limiting example, the individual web plate may be welded to the first side plate 200 and to the second side plate 210. Each of the one or more web plates 220 may be perpendicular to the first side plate 200 and to the second side plate 210.
The one or more web plates 220 may be contained entirely between a first boundary plane 214 defined to be coplanar with the front of the first side plate 200 and a second boundary plane 216 defined to be coplanar with the rear of the second side plate 210. The two or more coplanar timber elements 900 that are joined using the invention 100 may be contained entirely between the first boundary plane 214 and the second boundary plane 216.
In some embodiments, one or more of the individual web plates may be bent into a non-planar shape such that the bent web plate may contact more than one of the coplanar timber elements that are joined by the invention 100.
In some embodiments, the invention 100 may be operable to couple the joint of the roofing truss when the invention 100 is populated with less than a full complement of timber elements. As used herein, ‘the full complement of timber elements’ may refer to the maximum number of timber elements that an embodiment of the invention 100 was designed to join together at a single joint. As a non-limiting example, a center bracket 260 at the bottom center of the roofing truss shown in
