Roof construction

1. A roof apparatus, comprising:

a) multiple supporting members that are selected from purlins, channels, joists, U-beams or hat channels;

b) clip assemblies on said supporting members, each said clip assembly including a bottom member, a top member, and a sliding anchor;

c) multiple roof panels that each have an upper portion, a lower portion, wherein an edge portion of one said roof panel connects to an edge portion of another roof panel;

d) valley portions on each roof panel that enable collection of rainwater and a channeling of the rainwater to each roof panel lower portion, each valley portion having a bottom; and

e) a shear connection that fasten each roof panel to a sliding anchor above the valley portion bottom.

2. The roof apparatus of claim 1 further comprising a panel cap that connects to said roof panel at a said valley portion.

3. The roof apparatus of claim 2 further comprising a panel cap fitting that occupies a said valley portion and fasteners that connect said panel cap fitting to a said valley portion.

4. The roof apparatus of claim 1 wherein said sliding anchor is able to move in all directions relative to said top member.

5. The roof apparatus of claim 1 wherein said sliding anchor is able to move in multiple directions relative to said top and bottom plates.

6. The roof apparatus of claim 1 wherein said top member has spaced apart openings and each valley portion connects to said sliding member next to a said top member opening.

7. The roof apparatus of claim 1 wherein the shear connection includes fasteners that extend through a said panel cap fitting, a said bracket, and a said roof panel.

8. A roof apparatus, comprising:

a) multiple supporting members that are part of a building frame;

b) multiple roof panels that each have edge portions, an upper portion, a lower portion, wherein an edge portion of one said roof panel connects to an edge portion of another said roof panel;

c) a connection assembly that forms an interface between said support members and said roof panels that enables the roof panels to move 360 degrees relative to said supporting members;

d) said connection assembly including a bottom member, a top member having spaced apart top member openings, a sliding anchor that is movable in multiple directions relative to said top and bottom members and brackets that are connected to the sliding anchor; and

e) one or more fittings that connect the roof panels and brackets to said sliding anchors, each said fitting extending through a top member opening.

9. The roof apparatus of claim 8 further comprising a panel cap that connects to said roof panel at a said channel portion.

10. The roof apparatus of claim 9 further comprising a panel cap fitting that occupies a said valley portion and fasteners that connect said panel cap fitting to a said channel portion.

11. The roof apparatus of claim 8 wherein said sliding anchor is able to move in all directions relative to said top member.

12. The roof apparatus of claim 8 wherein each said support member is selected from a group that includes purlin, joist, hat channel, U-beam.

13. The roof apparatus of claim 8 wherein each valley portion has a U or V shape in transverse cross section.

14. A metal building apparatus, comprising:

a) multiple supporting members that are part of a framework;

b) multiple metal roof panels that each have a top portion, a bottom portion, an edge portion of one said roof panel connecting to an edge portion of another roof panel;

c) a bracket that includes multiple panels and multiple bracket valleys, said bracket positioned below said roof panels;

d) a connection assembly that forms an interface between said multiple support members and said roof panels;

e) said connection assembly including a bottom member, a top member having spaced apart top member openings and a sliding anchor that is movable in multiple directions relative to said top and bottom members;

f) one or more fittings that connect the roof panels to said sliding anchors, each said fitting extending through a top member opening; and

g) each supporting member having opposed, parallel webs, an upper plate having an upper surface, a lower end portion and multiple spaced apart reinforcing members that each connect to said webs.

15. The metal building apparatus of claim 14 further comprising a longitudinally extending passageway that enables carriage of electrical lines, piping or other wiring.

16. The metal building apparatus of claim 15 wherein said passageway is positioned below said reinforcing members.

17. The metal building apparatus of claim 15 wherein said webs are spaced apart a first distance and said passageway is a second distance wide that is a greater distance than said first distance.

18. The metal building apparatus of claim 15 wherein said passageway includes two spaced apart compartments with a gap in between said compartments.

19. The metal building apparatus of claim 14 wherein said bottom member is the upper surface of said upper plate.

20. The metal building apparatus of claim 15 further comprising piping contained in said passageway.
