Methods of assembly of prefabricated truss construction modules
The disclosure provides a method that includes providing or assembling a rectangular horizontal member, joining a vertical member to the rectangular horizontal member such that the vertical member bisects a length of the horizontal member and forms a T-junction at the horizontal member, joining first and second sloped members to the rectangular horizontal member and vertical member such that the first and second sloped members span from a top of the vertical member to opposing ends of the horizontal member, and joining first and second support members such that the first and second support members span from the T-junction between the vertical member and horizontal member to work points on an underside of each of the first and second sloped members. The structure thus formed can be assembled from prefabricated units shipped together in parallel planar orientation in a shipping container to provide a roof truss unit.
1 . A method, comprising:
providing or assembling a rectangular horizontal member;
joining a vertical member to the rectangular horizontal member such that the vertical member bisects a length of the horizontal member and forms a T-junction at the horizontal member;
joining first and second sloped members to the rectangular horizontal member and vertical member such that the first and second sloped members span from a top of the vertical member to opposing ends of the horizontal member, each first and second sloped member having a groove cut into an underside portion; and
joining first and second support members such that the first and second support members span from first ends disposed on either side of the T-junction between the vertical member and horizontal member to opposing second ends which only make direct contact with work points on the underside portion of each of the first and second sloped members at each groove, wherein the second ends of the first and second support members are precision cut male ends which are mated with each groove;
wherein no additional support members are joined such that each of the first and second sloped members has no more than one work point disposed on their respective underside portions between the top of the vertical member and each opposing end of the horizontal member.
2 . The method of claim 1 , wherein the rectangular horizontal member is a panel.
3 . The method of claim 1 , wherein the vertical member is a panel.
4 . The method of claim 1 , wherein the first and second sloped members are panels.
5 . The method of claim 1 , wherein first and second support members are planks.
6 . The method of claim 1 , wherein the rectangular horizontal member is a frame.
7 . The method of claim 1 , wherein the vertical member is a plank.
8 . The method of claim 1 , wherein the first and second sloped members are frames.
9 . The method of claim 1 , wherein the first and second support members are frames.
10 . The method of claim 1 , wherein the first and second support members are panels.
11 . The method of claim 1 , wherein the rectangular horizontal member, vertical member, first and second sloped members, and first and second support members are made of wood.
12 . The method of claim 1 , wherein when assembled together the rectangular horizontal member, vertical member, first and second sloped members, and first and second support members form a truss unit for manufacture of a roof structure.
13 . The method of claim 12 , further comprising joining a roof structure overlying the truss unit.
14 . The method of claim 13 , further comprising joining filler units representing ceiling panels or frames to flank on either side of the truss unit, wherein the roof structure is joined to overlie the truss unit and flanking filler units.
15 . The method of claim 13 , further comprising joining two truss units to flank a filler unit representing a ceiling panel or frame, wherein the roof structure is joined to overlie the filler unit and flanking truss units.
16 . The method of claim 14 , further comprising joining a plank spanning a top of the truss unit and a width of each of the flanking filler units, the plank forming a ridge to support the roof structure.
17 . The method of claim 15 , further comprising joining a plank spanning a top of the two truss units and a width of the filler unit therebetween, the plank forming a ridge to support the roof structure.
18 . The method of claim 13 , wherein the roof structure comprises panels overlying alternating truss units and filler units representing ceiling panels or frames.
19 . The method of claim 13 , wherein the roof structure comprises a frame, panels overlying the frame, and roofing material overlying the panels.
20 . The method of claim 19 , further comprising weaving a web of wiring to connect and compress members of the frame of the roof structure.
21 . The method of claim 1 , wherein the steps of the method are performed on the ground of a construction site.
22 . A method comprising loading a shipping container with first, second, and third planar prefabricated modules capable of forming the truss unit and roof structure of claim 14 as cargo in the interior of the shipping container through an open top of the shipping container, the prefabricated modules stacked vertically in parallel orientation.
23 . The method of claim 22 , wherein:
the first prefabricated module comprises the rectangular horizontal member;
the second prefabricated module comprises the vertical member, first and second sloped members, and first and second support members collapsed in parallel orientation to each other; and
the third prefabricated module comprises the roof structure.
