This application relates to building construction, and more specifically devices, systems, and methods for constructing buildings using pre-fabricated connectors and structural members that are formed from oriented strand board or similar manufactured wood products.
The home construction industry has been significantly challenged by a persistent shortage of skilled labor required for framing houses. This shortage has led to increased costs for hiring skilled laborers, making framing more expensive in terms of both time and money. The framing process itself can be lengthy, often exceeding 90 days on a single project. Additionally, scheduling delays to secure a quality framing crew, along with the extended framing process and subsequent delays in other construction activities, further escalate costs. This problem is even more acute in remote locations. Furthermore, the use of 2×4 or 2×6 wood stud construction in most wood-framed homes poses challenges such as warping and twisting which leads to waste or defective builds, necessitating additional material orders and complicating the maintenance of straight walls. Moreover, the traditional method of building each component-including vertical walls, studs, trusses, loft joists, and floor joists-separately and on-site introduces potential errors, diminishing the structural integrity of the building and complicating the construction process.
One embodiment provides a system for building construction, comprising: a first and second plate-shaped connector each comprising a first and second arm portion that each include multiple bolt holes arranged in a matching pattern; and a first and second I-beam-shaped structural member, wherein each structural member has a first end and a second end that each include multiple bolt holes arranged in the matching pattern, wherein the first and second connectors are adapted to couple the first and second structural members end-to-end by forming a three-layer sandwich comprising a first outer layer that is the first connector, an inner middle layer that is the first end of the first structural member and the second end of the second structural member, and a second outer that is the second connector, wherein the pattern of bolt holes of the first end of the first structural member is in alignment with the pattern of bolt holes of the first arm of the first and second connector, wherein the pattern of bolt holes of the second end of the second structural member is in alignment with pattern of bolt holes of the second arm of the first and second connector, and wherein the first and second connectors and the first and second structural members are removably coupled to one another via bolts through the aligned multiple bolt holes in the connectors and structural members.
In some embodiments, the connectors and structural members are formed from oriented strand board. In some embodiments, an angle between the arms of the first and second connector is less than 180 degrees. The first and second connectors may be elbow connectors where the angle between the arms is 90 degrees. The first and second connectors may be roof connectors, where the angle between the arms is one of standard roof pitches between 1:12 and 12:12. The arms of the first and second may be connected by a through bolt that forms a hinge, such that an angle between the arms is selectable by a user, wherein the angle can be fixed by tightening a bolt threaded to the through bolt. The connectors may be T-connectors that each include a third arm. The structural members may include one or more holes adapted to receive utilities, including one or more of water pipe, vent pipe, electric conduit, or electrical cable.
In some embodiments, the system further includes a first I-beam shaped lateral connector that has a first end and a second end, wherein each end has (1) a tenon that includes a hole and (2) a receptacle cut-out matching the shape of the tenon, wherein each of the structural members include mortise adapted to receive the tenon, wherein the first lateral connector is adapted to connect the first structural member to a third I-beam shaped structural member, such that, when connected: the first and third structural members are in a parallel orientation to one another; the first lateral connector is between and perpendicular to each of the first and third structural members; the tenon of the first end of the first lateral connector extends through one of the mortises of the first structural member, wherein the first lateral connector is secured to the first structural member by a peg, dowel or pin positioned in the hole in the tenon; and the tenon of the second end of the first lateral connector extends through one of the mortises of the third structural member, wherein the first lateral connector is secured to the third structural member by a peg, dowel or pin positioned in the hole in the tenon.
In some embodiments, the system may further include a second I-beam shaped lateral connector that has a first end and a second end, wherein each end has (1) a tenon that includes a hole and (2) a receptacle cut-out matching the shape of the tenon, wherein the second lateral connector is adapted to connect the first structural member to a fourth I-beam shaped structural member, such that, when connected: the first and fourth structural members are in a parallel orientation to one another, wherein the first structural member is between the second and fourth structural members; the second lateral connector is between and perpendicular to each of the first and fourth structural members; the tenon of the first end of the second lateral connector extends through one of the mortises of the first structural member; the tenon of the second end of the second lateral connector extends through one of the mortises of the third structural member; and the tenon of the first end of the second lateral member extends into the receptacle cut-out at the first end of the first lateral connector.
The mortises in the structural members that are adapted to receive the tenon may be rectangular, wherein the tenons at each end of the first lateral connector may be rectangular and adapted to fit through the mortises in the structural members. The first and second plate-shaped connectors may each include two rectangular-shaped mortises configured to receive the tenon at either end of the first lateral connector, such that, when the first lateral connector is connected to the first structural member: the tenon at the first end of the first lateral connector passes through (1) one of the rectangular-shaped mortises in the first plate-shaped connector, (2) a mortise at the first end of the first structural member, and (3) one of the rectangular-shaped mortises in the second plate-shaped connector; and the tenon at the first end of the first lateral connector is secured via a peg, dowel, or pin through the hole at the end of the tenon.
Other embodiments provide a method of constructing a building, comprising: forming a first wall on a concrete slab or wooden deck by: placing multiple I-beam shaped structural members on the ground in an array; connecting adjacent structural members to one another using multiple lateral connectors, wherein each lateral connector has a tenon at each end that inserts into a mortise in one of the structural members; and for each of the structural members, connecting two plate-shaped elbow connectors at one end of the structural member, such that the two elbow connectors sandwich the end of the structural member, wherein the connectors and the structural member are connected by bolts passing through aligned holes in the connectors and structural members.
The method may further include standing the first wall; attaching the first wall to the concrete slab or wooden deck; forming a second wall from an array of structural members connected to one another via multiple lateral connectors, wherein each of the structural members has an attached elbow connector at one end; standing the second wall; and attaching the second wall to the concrete slab or wooden deck.
The method may further include connecting an I-beam shaped structural member to each of the elbow connectors of each wall thereby forming a roof member; connecting each roof member to a corresponding roof member from the other wall using a two plate-shaped roof crown connectors; and connecting lateral connectors to adjacent roof members.

In an exemplary preferred embodiment, the present invention employs 9½″ or 12″ structurally engineered beams (103,
The system generally includes structural members (e.g., I-beam, joists) and connective components (e.g., an elbow connector, a T-connector). Any of these structural members and connectors may have one or more pre-cut holes or knock-outs for the passage of utilities. Typically, the builder will align a hole in a connector with a corresponding hole in a structural member so that there is clear passage through the combined structure.
Structural beams are securely assembled using dowels, bolts, washers, and nuts. (See
More specifically, the component fittings of the present invention allow T-connector, 45 connector, 90 connector, and crown connectors to be sandwiched and bolted to the I-beam. The I-beam is machined with predetermined slots and holes that correspond to the unique component fittings, as described herein. These engineered slots and holes are used to securely connect all the components during the construction process, ensuring the structure remains square and preferably on a two-foot center. (See
In the preferred embodiment, the 45 connector is sandwiched and bolted to both a vertical wall stud and a roof truss, with a pitch angle ranging from 1-12 to 12-12 (see
SB (“Small Building”) and SBX (“Large Small Building”) connectors are lateral connectors that are used to connect vertical I-beams to one another. The SBX connector 901 connects each vertical I-beam and is pinned with a dowel or bolt to hold the vertical I-beam together, acting as a fire stop in compliance with fire code (see

View 840 is a perspective environmental view showing connector 801 being used to laterally connect two adjacent I-beams 103 in an array of I-beams that forms, for example, a wall. View 850 is a front cutaway view of connector 801 being used to connect two I-beams 103. This view also shows interlocking tenons 853 from adjacent SB connectors.
While the elbow connector 1601 is a unitary plate of oriented strand board, we can speak of it as having two arms 1602 and 1603 arranged at an angle 1604 with respect to one another. The connector 1601 also include rectangular slots (mortises) 1611 configured to receive the tenons (or fingers, tongues) of an SB, SBX, or similar connector.
As can be seen in views 1620 and 1630, the connector 1601 can be used with another elbow connector 1605 to sandwich the end of an I-beam member 1606. Each arm and the end of the I-beam member 1606 has a pattern of through holes which, when are aligned with one another such that the sandwich of elbow connectors and I-beam can be locked down by the use of bolts, nuts, and washers. In views 1610 and 1630 the alignment of pre-cut holes for utilities is also shown.
The central member 1806 of the I-beam includes cutaway utility holes (or knock-outs), slots (mortises), and bolt holes. The bolt holes are used to receive bolts when attaching connectors such as the elbow, extension, or T-shaped connectors described above. The slots are adapted to receive the tenon (also referred to as “tongue” or “finger”) members of lateral connectors, such as those shown in
