Premanufactured structures for constructing buildings
Premanufactured structures for constructing buildings comprise a construction system for an energy efficient multi-story building with standard single or mixed units. The multi-story building is constructed using premanufactured structures: non-weight bearing walls with finished exterior including all electrical, insulating, plumbing and communications components that are premanufactured at a site distant from a building site, and the non-weight bearings walls are attached to a floor and ceiling slabs, interfacing with each other to enclose units of the building; interior components that are premanufactured at a remote site to connect to inside portions of the non-weight bearing walls; and exterior components that are premanufactured at the remote site to attach to exterior surfaces of the building. Non-weight bearing walls, interior components, and exterior components are installed and connected together to provide the energy efficient multi-story building with units with different floor plans, and optionally, a retail level with underground parking.
1. A wall comprising:
a plurality of metal studs;
an acoustical insulation layer woven between the plurality of metal studs;
a first inner wall panel adjacent to the acoustical insulation layer;
a second inner wall panel adjacent to the acoustical insulation layer on a surface opposite the first inner wall panel;
a head section on a top portion of the plurality of metal studs, an inside of the head section lined with magnesium oxide boards, wherein vertical sides of the head section are offset and spaced inwardly from the first and second inner wall panels; and
a base section on a bottom portion of the plurality of metal studs, an inside of the base section lined with magnesium oxide boards, wherein vertical sides of the base section are offset and spaced inwardly from the first and second inner wall panels.
2. The wall of claim 1 , further comprising an L-shaped base support member configured to receive the base section.
3. The wall of claim 2 , wherein the L-shaped base support member is configured to be coupled to a floor.
4. The wall of claim 3 , further comprising fire-resistant caulk between the floor and the base section.
5. The wall of claim 1 , further comprising an L-shaped head support member configured to receive the head section.
6. The wall of claim 5 , wherein the L-shaped head support member is configured to be coupled to a ceiling.
7. The wall of claim 6 , further comprising a pad between the L-shaped head support member and the ceiling.
8. The wall of claim 7 , wherein the pad comprises neoprene.
9. The wall of claim 6 , further comprising a fire-sealant tape between the ceiling and the L-shaped head support member.
10. The wall of claim 6 , further comprising fire safing materials between the head section and the ceiling.
11. The wall of claim 5 , wherein the head section is secured to the L-shaped head support member by a horizontal support fastener.
12. The wall of claim 11 , wherein the L-shaped head support member includes a slot configured to accept the horizontal support fastener and allow vertical movement of the horizontal fastener within the slot.
13. The wall of claim 1 , wherein the first and second inner panels comprise magnesium oxide board.
14. A method of installing a demising wall, the method comprising:
securing a head section of a demising wall to an L-shaped head support member coupled to a ceiling at a desired location of the demising wall; and
securing a base section of the demising wall to an L-shaped base support member coupled to a floor at the desired location of the demising wall;
wherein the demising wall further comprises a plurality of metal studs, an acoustical insulation layer woven between the plurality of metal studs, and first and second wall panels on opposite sides of the metal studs,
wherein the head section is provided on a top portion of the plurality of metal studs, an inside of the head section is lined with magnesium oxide boards, and vertical sides of the head section are offset and spaced inwardly from the first and second inner wall panels, and
wherein the base section is provided on a bottom portion of the plurality of metal studs, an inside of the base section is lined with magnesium oxide boards, and vertical sides of the base section are offset and spaced inwardly from the first and second inner wall panels.
15. The method of claim 14 , further comprising attaching a trim along the base section and head section of the demising wall, wherein the trim is configured to conceal the L-shaped head support member and the L-shaped base support member.
16. The method of claim 15 , wherein the trim comprises aluminum.
17. The method of claim 14 , further comprising sealing with a caulk open spaces between the floor and the base section.
18. The method of claim 14 , further comprising filling a gap between the ceiling and the head portion with fire safing materials.
19. The method of claim 14 , wherein securing the head section to the L-shaped head support member comprises passing a horizontal fastener through the L-shaped head support member and at least partially through the head section and wherein securing the base section to the L-shaped base support member comprises passing a horizontal fastener through the L-shaped base support member and at least partially through the base section.
20. The method of claim 14 , further comprising coupling a finished panel to a vertical surface of the demising wall.
21. The wall of claim 1 , wherein the vertical sides of the head section are spaced from the first and second inner wall panels by a first pair of horizontal flanges, and wherein the vertical sides of the base section are spaced from the first and second inner wall panels by a second pair of horizontal flanges.
22. The wall of claim 1 , wherein the insides of the head and base sections are lined with magnesium oxide boards arranged parallel to the first and second inner wall panels.
