View Patent ↗A prefabricated building module is described. The building module may provide structural stability for a building, including when stacked with like building modules. The building module may provide a service riser for the building. The building module may provide fixtures for the building, including bathroom, kitchen and laundry fixtures. Also described is a building including prefabricated building modules and a method of constructing a building using prefabricated building modules.
1. A prefabricated building module for a building structure, wherein said prefabricated building module comprises:
at least one wall section of cross-laminated timber extending vertically between the upper and lower peripheral edges of the prefabricated building module,
wherein a cross-laminated timber of the at least one wall section of cross-laminated timber extends vertically from the upper peripheral edge to the lower peripheral edge of the prefabricated building module,
wherein said at least one wall section of cross-laminated timber is reinforced with at least one elongated structural section extending vertically from the upper peripheral edge of the prefabricated building module to the lower peripheral edge of the prefabricated building module, and said at least one elongated structural section is at least one parallel flange channel (PFC) section, and
wherein the prefabricated building module is configured to be securable in a stack of a plurality of prefabricated building modules so that one or more resulting columns of said cross-laminated timber of the at least one wall section of cross-laminated timber acts as a loadbearing structure for the building structure.
2. The prefabricated building module according to claim 1 , wherein said at least one parallel flange channel (PFC) section is provided in a recess formed in an outer surface of the at least one wall section of cross-laminated timber that is reinforced with at least one elongated structural section.
3. The prefabricated building module according to claim 1 , wherein the prefabricated building module is configured such that, when the prefabricated building module is secured in a stack of like prefabricated building modules, one or more resulting columns of said parallel flange channel (PFC) sections act as a loadbearing structure for the building structure.
4. The prefabricated building module according to claim 3 , including a floor of cross laminated timber prefabricated building module.
5. The prefabricated building module according to claim 4 , including a roof of cross laminated timber prefabricated building module.
6. The prefabricated building module according to claim 5 , including a ceiling section provided below at least a portion of the roof such that a services cavity is formed between the roof and the ceiling.
7. The prefabricated building module according to claim 6 , comprising a front side wall, a rear side wall, a left end wall and a right end wall, wherein said front side, rear side, left end and right end walls are arranged in combination with the roof and the floor to form a generally rectangular prism, and wherein the at least one wall section is at least part of at least one of the front side, rear side, left end and right end walls.
8. The prefabricated building module of claim 7 , further comprising at least one internal dividing wall for the prefabricated building module.
9. The prefabricated building module of claim 6 , further comprising a services connector on an external side of the prefabricated building module, for providing at least one service incorporated in the services cavity to a location external to the prefabricated building module.
10. The prefabricated building module of claim 9 , wherein the services connector is adapted to connect to a complementary connector in a wall structure to be fixed to the exterior of the prefabricated building module.
11. Parts for assembly of a building structure, the parts comprising:
a first plurality of stackable prefabricated building modules according to claim 1 for forming a first stack of prefabricated building modules;
a second plurality of stackable prefabricated building modules according to claim 1 for forming a second stack of prefabricated building modules;
components, different from the prefabricated building modules, for spanning a first distance between two said stacks of prefabricated building modules;
components, different from the prefabricated building modules, for spanning a second distance between two said stacks of prefabricated building modules, the second distance different from the first distance.
12. The parts for assembly of a building structure of claim 11 , wherein said at least one elongated structural section of each prefabricated building module is at least one parallel flange channel (PFC) section provided in a recess formed in an outer surface of the at least one wall section of cross-laminated timber that is reinforced with at least one elongated structural section.
13. A building structure comprising a plurality of prefabricated building modules arranged so as to form a vertical stack, each prefabricated building module comprising:
at least one wall section of cross-laminated timber extending vertically between the upper and lower peripheral edges of the prefabricated building module,
wherein a cross-laminated timber of the at least one wall section of cross-laminated timber extends vertically from the upper peripheral edge to the lower peripheral edge of the prefabricated building module, and
wherein said at least one wall section of cross-laminated timber is reinforced with at least one elongated structural section extending vertically from the upper peripheral edges of the prefabricated building module to the lower peripheral edge of the prefabricated building module, so that one or more resulting columns of said cross-laminated timbers of a plurality of wall sections of cross-laminated timber and one or more resulting columns of said at least one elongated structural sections in the vertical stack act as a loadbearing structure for the building structure, and the at least one elongated structural section is a parallel flange channel (PFC) section.
14. The building structure of claim 13 , wherein said at least one elongated structural section of each prefabricated building module is at least one parallel flange channel (PFC) section provided in a recess formed in an outer surface of the at least one wall section of cross-laminated timber that is reinforced with at least one elongated structural section.
15. The building structure of claim 14 , wherein:
the building structure includes a plurality of said stacks; and
the plurality of stacks provide primary stability for the building.
