Description
SPECIFICATION
Prefabricated curb unit for a standing roof seam
The present invention relates in general to building structures, and, more particularly, to the assembly of roof structures.
Frequently, building equipment, such as fans, air conditioning units, or the like, are supported on the roof of a building. Such equipment requires installation of a roof curb unit.
Butler Manufacturing Company manufactures .roof panels under the Trademark "MR-24".
These roof panels are interlocked using a double lock standing seam.
Heretofore, there has been no roof curb unit available which is compatible with the Butler
MR-24 roof in a prefabricated manner.
In accordance with the present invention, there is provided a method of installing a roof curb with a roof having standing seams between adjacent roof panels, which comprises (1) installing a plurality of roof panels having edges arranged for interlocking by seaming; (2) seaming interlocked edges of the roof panels over most of the roof except for edges adacent an intended open area; (3) installing a roof curb having peripheral extensions into the open area; and (4) completing the seaming of the partially-seamed edges together with peripheral extensions of the roof curb to form a solid seal of the roof curb with the roof.
The roof curb unit used in the present invention is a prefabricated unit which can be seamed directly into the Butler MR-24 roof structure.
Such a roof curb unit is very watertight and presents a very high quality construction.
The curb unit used in the present invention may include a welded and closed cricket. The cricket is an integral part of the curb walls and adds strength to the overall curb design.
The cricket sheds water and eliminates water ponding on the upslope portion of the curb.
The curb walls and cricket are preferably constructed of 16 gauge "GALVALUME" (Trademark) material. A special welding procedure may be used to join the cricket and curb walls to an MR-24 panel of a predetermined length.
After welding, the curb and MR-24 panel become an integral unit.
The curb and MR-24 panel unit is placed on the roof according to a pre-roof layout plan, and is seamed into the MR-24 roof panel system, and thus becomes an integral part of the
MR-24 roof system.
The invention is described further, by way of illustration, with reference to the accompanying drawings, in which:
Figure 1 is a perspective view of one embodiment of a prefabricated curb unit used in the present invention;
Figure 2 is a perspective view of an MR-24 roof prepared to receive the prefabricated curb unit shown in Fig. 1;
Figures 3 and 4 are perspective views showing the installation of the prefabricated curb unit of Fig. 1 into the MR-24 roof of Fig.
2;
Figure 5 is a perspective view showing the underside of the prefabricated curb unit of Fig.
1;
Figure 6 is an exploded perspective view showing insulation of the curb unit of Fig. 1;
Figure 7 is an elevational sectional view taken along line 7-7 of Fig. 6; and
Figure 8 is an elevational view in cross-section of the double lock seam between panels.
Referring to the drawings, shown in Fig. 1 is a prefabricated roof curb unit 10 which can be seamed into a roof panel, such as roof panel RP shown in Fig. 2, which preferably is part of an MR-24 roof manufactured by Butter
Manufacturing Company. The roof includes building structural support means, such as purlins P, having a blanket B of insulation thereon and thermal spacer blocks SP on the insulation blanket (see Fig. 3). The roof panels RP are supported on the thermal spacer blocks and the insulation blanket. A full disclosure of such a system is contained in U.S. Patent No.
4,348,846, issued on September 14, 1982.
The roof curb unit 10 includes a one-piece elongate panel 14 having side edges 18 and 20 and end edges 22 and 24. The panel 14 is part of an MR-24 roof, and includes seaming means 30, 32 and 34 which are located on each side edge and also centrally of the panel, respectively. The panel 14 has co-planar portions 14' and 14" extending between seaming means 30 and 32 and 32 and 34 respectively. Seaming means 30 and 32 are fully described in the aforementioned U.S. Patent No. 4,348,846. The MR-24 roof panels, and the mounting thereof, as by a seaming machine SM, such as a ROOF RUNNER (Trademark) seaming machine, or the like, is also fully disclosed in U.S. Patent No. 3,120,828.
As discussed in U.S. Patent No. 3,120,828, the standing seams are all double lock standing seams. One such seam is shown in Fig. 8.
The seaming means includes sloping first sides 36 and sloping second sides 38 with shoulders 40 and 42 extending horizontally therefrom. An upstanding flange 44 is mounted on the shoulders to be incorporated into a roof seam when the roof panels are mounted. As discussed in the aforementioned
U.S. Patent No. 3,120,828, the roof panels are mounted on roof purlins with spacer blocks and blanket insulation providing thermal integrity to the roof. The interconnected panels are RP1, RP2, RP2-21 and RP3 as shown in Fig. 2.
The roof curb unit 10 further includes a corrugation 240 located centrally thereof to be positioned beneath a panel seam 242 when assembled with the roof panel, as best seen in Fig. 3.
The roof curb unit 10 also includes a rim means welded to the panel 14 to form an integral unit. The rim means includes a pair of side panels 50 and 52, a pair of end panels 54 and 56 and an L-shaped rim portion 60 surrounding a curb opening 70 defined in the panel. A closed triangular cricket 74 is welded to the end panel 56 of the curb rim means 60 and serves as. a water guide. The cricket 74 has apex 76 located up-slope of the curb unit 10 so water is shed from the curb unit.
Referring to Figs. 2, 3 and 4, installation of the curb unit 10 into a roof panel system
MR-24 in accordance with the present invention is easily understood. Two roof panels
RP2 and RP22 have a cut out opening 90 defined therein. The unit 10 is inserted into the cut out opening 90 with leading end 22 positioned beneath the up roof portions of panels RP2 and RP2-21 and aft end 24 positioned on top of the down roof portions of panels RP2 and RP22. The seaming means 34 is accommodated by a portion of the seam 94 connecting panels RP2 and RP2-21, and on top of the continuation of that seam.As best seen in Fig. 2, all seams are full seams, except for seams 100 and 102, which are partial seams and accommodate the seaming means 30 and 32, respectively, to interjoin the curb unit 10 with panels RP1, RP2, RP221 and RP3. The partial seams 100 and 102 are shown in Fig. 2 to be incompletely folded over, that is, the double lock stops at the location whereat the curb ends join the roof panel seams. The double lock seam is located at all other locations, however. Appropriate support channels 110 can be mounted on the purlins to further support the curb 10 when mounted, if suitable.
Suitable attaching means, such as straps 120, splice plates 122 and fasteners 124, are used to attach the curb unit to the panel RP2 and panel RP221. As discussed in the aforementioned Patent No. 4,348,846 as to the use of gauges 200, 201, the panel straps themselves can be used as tempiates to ap propriateiy mark the roof panels. The straps 120 can also be used to appropriately mark the curb 10 as weil. Field holes 130 can be located and drilled.
Insulation can also be included in the curb unit 10, as best seen in Figs. 6 and 7. An insulation collar 140 is attached by fasteners, such as bolts 142, or the like, to the curb unit sides 50, 52 and ends 54, 56, as indicated in Figs. 6 and 7.
Insulation 144 is positioned between the collar 140 and curb unit 10, and the collar 140 is attached to the roof insulation B by a channel 150, or the like. Insulation 144 can be rigid, if suitable. The collar 140 can be one-piece, or a plurality of interjoined pieces, as desired, and as indicated in Fig. 6.
After the curb 10 is installed in the roof panels MR-24, sealant can be used to ensure proper sealing around the curb.
By incorporating the curb unit into the roof panel, building equipment requiring a curb unit, for example, fans and air conditioning units, may be installed on the roof of a building roofed by such roof panels, including the Butler MR-24 roof structure.
In summary of this disclosure, the present invention comprises a novel curb unit which can be directly seamed into a roof structure, so that building equipment may be supported on the roof. Modifications may be made within the scope of this invention..
