Description
`` 11~3583 This application is a division of Canadian Serial No. 310,198, fil~d Aug~st ~, 197~.
~ C;~OUN~ ~L` lll~: IN~IN~
The roof structure of an inclustrial building typically comprises rafter beams which extend parallel to one another across the building and slope from the center of the building down toward its sides, arld t~urlills which extend parallel to one another and W}liCh ~x~cnd across and are mounted on the rafter beall)s. I~ard s~lcet~. <?I c~teri~r roofing mateeial extend over and ~re att~lche~l to the purlins. In the past, when a rooE structute of an industrial building was to be insulated, elongated sheets of insulation material were stretched across the purlins and the sheets of hard roofing material wer~ atl:ached to the purlins through the insulation material. The relatively thin sheets of insulation material were ayplied to the roof structure by the workmen using th~ sheets o hard roofing material which were already installed in the roof structure as a working surface. Reels of insulation material were first unwound on the hard sheets Or roofing material and the long sheets of insulation material were move~ by hand over onto tl-e e~cposecl ~urlins ~d~ ellt tl-c hard roofing material and the lengths of the slleets o~
insulation material extended across tlle lcnc3ths of the purlins. The sheets of insulation material were stretched to prevent sagging between the purlins, and the hard roofing material was then placed over t)le insulation material and connected to the purlills.
As set orth in my prior U.S. ~a~ent No.
3,559,91~, it has now become common pracLice tc~ cx~cnd the sheets of insulation material along the lengths of the .. -1- ~
11~8583 purlins, instead of across the P1~rlins, so as to climinatc the seams between adjacent sheets of insulation material from being exposed inside the building. The new procedure as set forth in my patent has reduced hazards to workmen on the roof by ~alnt-aining the reels of insulation material in a relatively static and available position Oll the exposed purli]ls wit11out e~posin~
long lengths of a sheet of material to the wind while the workmen remain on the sheets of hard roofing material, so that the occasio11s when the workmen might be tempted to walk or climb out on the pur-lins to place or adjust the sheets of insulation material have been reduced.
SUMMARY OF THE INVENTION
.:
The invention comPrises an`insulated roof structure which includes improved means for insulating the roof structure. The rool structure can be comprised of a plurality of rafters spaced approximately parallel with respect to one another. The rafters support a plurality of purlins which are spaced approximately parallel with resDect to one another and extend acro~s.s the ra~ters.
Each of the purlins includes an upper laterally extending flange, a central web and a lower laterally extending flange. Sheets of hard roofing material are supported by the upper laterally extend-ing flanges of the purlins. Fasteners connect the sheets of hard roofing material to the upper laterally extending flanges of the purlins. Elongated strips of flexible sheet material extend along the lengths of the spaces between t~1e p~ c al~cl ~pa~ .` s~-a(-ec between adjacent ones of the purlins. The outer edges of the strips of flexible sheet material rest on the top surfaces of the upper laterally extending flanges of adjacent ones of the purlins.
Portions of the strips between the purlins extend down to a lower level into the space between the central webs oE the purlins and form troughs between the purlins. Insulation material, such as loose or batten heat insulation is positioned in the trouyhs of the sheet material and substantially fills the trouyhs up to the sheets of hard roofing mal:erial.
The invention further teaches a method for installing insulation to a roof structure. The ste~s COIlSi~ cr unrcc~in-l sheet material of a width wider than the space between adjacent purlins. The unreeling may be accomplished by supporting reels of the sheet material on pairs of adjacent purlill alld movillg each reel along the lengths of the purlins, thUS unrecling the sheet material. The unreeled portion of the sheets are formed in a trouah-shape between adjacent ones of the purlins with the edge portions of the sheets of material positioned Oll the uyper surfaces of the upper flanges of the purlins. The edge portions of adjacent sheets of material are sealed together placing heat insulation material in the troughs of the sheets of material.
Hard sheets of roofing material are placed over the insulation material and purlins. Alternately elongated flexible sheets of material of a width wider than the spaces between adjacent purlins are placed along the lengths of adjacent purlins and over the spaces between adjacent purlins. The sheet material is formed as it is placed on the purlins to locate the edge portions of the sheets of material on the upper surfaces of adjacent purlins to locate the central portion of the sheets of material at a lower level between the purlins. The edge portions of adjacent sheets are sealed together, and insulation material is place-l on thc central portions of the sheet material.
The sheet material can be of varying width but, prefer-ably, is at least wider than the distance between mid-points on the top flanges of adjacent ones of purlins. Thc wider thc sheet material, the further the i8583 ~aterial can hang down between the adjacent purlins rcsulting in a deeper trough and thus a thicker layer of insula-tion can be supported by the trough. The side edges of the flexible sheet material rest on the top surfaces of the upper laterally extending flanges of the adjacent ones of purlins while the center portion of the sheet material sags into the space between the purlins. The flexible sheet material in the disclosed embodiment is supported by a lattice of support straps bclow t]lC
sheet material extending through openings in ~he purlil-c; or resting on the rafters, or by attaching the sheet material at its side edges to the purlins.
In the preferred embodiment of the invention, the outer edges of the sheet material overlap, on the upper laterally extending purlin flanges, the outer edges of similar adjacent sheets extending between the next pair of purlins.
These outer edges are held in place by the fastening of the metal roofing panels to the purlins.
Also taught by this invention is the use of foam board or other solid insulation material to cover insulation gaps created by the metal purlins and the gaps between the purlins between the hanging troughs. Solid insulation material is fastened to the upper and lower flanges of the purlins. The solid insulation board covering the upper laterally extending flanges of the purlins can take the form of a board just wide enough to cover one of the purlins or it can be wide enough to span the space between adjacent purlins. The solid insulation material covering the lower extending flange of the purlin need only be wide enough to cover the flange and possibly any gaps beneath the upper laterally extending flange of the purlin to which it is attached and the flexible sheet material.
Thus the present invention seeks to provide an ,r~
~improved insulated roof stru ~ Qe8 ~e~ein insulation in the form of either loose or batten insulation can be expediently installed in the roof structure in varying desired thicknesses.
Briefly described, in this divisional application the invention comprlses an apparatus for installing insulation material in the roof of an industrial building and the like. A
. .
framework supports a reel of sheet material of a width greater ~ than the distance between a pair of adjacent parallel purlins in ; the roof structure. The sheet material is paid out from the, reel. Guide means guide the framework along a pair of adjacent parallel purlins in the roof structure. Means mounted on the framework and extending below the guide means, at distances ;~ apart which are less than the distance between adjacent ones of -~ the purlins, protrude downwardly between the adjacent parallel purlins and urge the central portion of the width of the sheet material downwardly between the adjacent ones of the purlins, while the edge portions of the sheet material remain on the upper surfaces of the adjacent purlins.
Other aspects, features and advantages of the present -~
invention will become apparent upon reading the following specificatlon, when taken in conjunction with the accompanying drawings.

Referring now in more detail to the drawings, in which like numerals indicate like parts throughout the several vie-~s, Fig. 2 illustrates the roof structure 9 which includes a plurality of spaced parallel purlins mounted on rafters 18. The purlins 1 each include a central web 2, lower flange 3 and upp~r flan~e 4.
A flexible sheet material 5 is unrolled along the upper flange 4 of adjacent ones of purlins, as shown in Fig. 1. The outer edges 6 of the sheet material are left on the upper laterally extending edyes 4 of the puLlins 1.
The elongate center portion of the sheet material sags down between the central web 2 of adjacent ones of purlins 1, thus forming a trough 7~ The trough is filled ~ith insulation material 8, loose or batten. If batt or blanket-type insulation 8 is used, the shape of the structure is more flat, as shown in the drawillgs~ If loose insulation is used, a more sagging appearance is created in the strips of flexible sheet material 5, but a more stiff 2Q sheet material 5 tends to provide a more unifolm appearance. Abutting edges 6 of adjacent sheets of flexible material 5 overlap one another on top of the upper flange 4 of purlins 1 as shown in Fig. 2 at 10 an~ aee held in place by the fastening of metal roof panel 12 to the upper flange 4 of purlin 1. Preferably, the overlapping edge- portions of -the strips of sheet material 5 are connected together as by adhesive or by heat sealing, depending on the characteristics of the material, the climate conditions and working conditions. This provides an effective vapor barrier beneath the hard roofing material.
lattice of support straps or banding is formed .
5~3 in the roof structure, with the lattice comprising cross straps 11 under tension extencling thro~lclll opel~ s in the central webs 2 of the purlins 1 and with longitudinal straps 13 extending parallel to the lengtlls of the purlins.
The lattice is used as an aid in supporting the bottom side of the trough 7. The support lattice can be formed from cross straps 11 extending through the pllrlills without the longltudinal straps 13, or the lattice can comprise longitudinal straps 13 res~ing on the ra~ters 18 (Fig. 3).
Figs. 3 and 4 show the use of solid insulation board for insulating the gaps between the insulation troughs 7. The upper flange 4 of purlins 1 can be insulated by placing along the top edge o~ the upper flange 4 a piece of solid insulation board 14 which is only slightly wider than the upper flange 4 itself or, an insulation board 16 can be used which rests on the top side of the upper lateral flange 4 and spans the entire space between adjacent ones of purlins. The underside of the Z0 purlins has a slightly wider gap to insulate and as a result slightly wider or insulation board 16, 17 is used to insulate the gap. If the channel insulation formed by the strips of sheet material 5 rest on a support lattice 11-13 that is mounted on the rafters 18 of the building, flat insulation board 16 (Fig. 3) can be used by directly riviting the insulation boards to the bottom surface of the lower flanges 3 of the purlin. If, however, the channel insulation is supported by the lattice of support straps at a higher elevation (Fig. 4) a channel-shaped board 17 is used with side flanges 20, and additional straps 19 can be placed over the rafters lB to engage the flanges as illustrated, or the straps 13 in the support lattice 11-13 on opposite sides of the purlins can be used (not shown).
The insulation board can be fabricated from various suitable materials ,such as glass reinforced cellular plastic isocyanurate insulation, ' ~s illustrated in ~igs. 1 and Sr the rcel support framework 24 comprises a pair of triangular side frames ~,5 and 26 and lower spacer bars 28, 29 and 30 extending across the bottom of the framework. A reel 31 oE t}le flexible sheet material is supported at the' upper apexes o~ t:he triangular side frames 25 and 26 on support bar 32, and the free end of the sheet material moves from the reel 31 beneath lower spacer bars 29 and 30. Bottom runnecs 34 and 35 are mounted on the bottom of the framework 24 and hold the framework on a pair of adjacent ones of the purlins 1.
- A pair of sheet guides 36 and 38 are slidably mounted on the rear spacer bar 30, and clamps 39 and 40 of the sheet guides are slidably mounted on the bar 30. Set screws 41 allow the clamps 39 and 40 to be attached to tl-e bar 30 at variable positions along the length of the bar. U-shaped guide elements 42 are mounted on the clamps 39 and 40 and project downwardly from the framework into the space between adjacent ones of the purlins- When the framework is pushed along the purlins, the sheet material unrolls from its reel 31, passes beneath the lower spacer bars 29 and 30, and the sheet guides 36 and 38 urge the central ~85~3 i portion of the strip of sheet material down~ rtll~ between the purlins. The side edge portions of the strip of sheet material are therefore guided onto the top surfaces of the upper flanges 4 of the purlins 1.
When the strip of sheet material has been ormed in the manner illustrated in Fig~ 5, by forming a trough between the purlins, the insulation material is then placed in the trough. For example, ]oose insulation can be blown into the troughs, batt insulation can be placed by workers standing on the already installed hard roofing material down into the troughs, or blanket insulation can be fed from reels down into the troughs.
It will be understood that the foregoing relates only to a disclosed embodiment of the present invention, and that numerous changes and modifications may be made therein within the scope of the invention as defined in the following claims.

SUMMARY OF THE INVENTION
.:
The invention comPrises an`insulated roof structure which includes improved means for insulating the roof structure. The rool structure can be comprised of a plurality of rafters spaced approximately parallel with respect to one another. The rafters support a plurality of purlins which are spaced approximately parallel with resDect to one another and extend acro~s.s the ra~ters.
Each of the purlins includes an upper laterally extending flange, a central web and a lower laterally extending flange. Sheets of hard roofing material are supported by the upper laterally extend-ing flanges of the purlins. Fasteners connect the sheets of hard roofing material to the upper laterally extending flanges of the purlins. Elongated strips of flexible sheet material extend along the lengths of the spaces between t~1e p~ c al~cl ~pa~ .` s~-a(-ec between adjacent ones of the purlins. The outer edges of the strips of flexible sheet material rest on the top surfaces of the upper laterally extending flanges of adjacent ones of the purlins.
Portions of the strips between the purlins extend down to a lower level into the space between the central webs oE the purlins and form troughs between the purlins. Insulation material, such as loose or batten heat insulation is positioned in the trouyhs of the sheet material and substantially fills the trouyhs up to the sheets of hard roofing mal:erial.
The invention further teaches a method for installing insulation to a roof structure. The ste~s COIlSi~ cr unrcc~in-l sheet material of a width wider than the space between adjacent purlins. The unreeling may be accomplished by supporting reels of the sheet material on pairs of adjacent purlill alld movillg each reel along the lengths of the purlins, thUS unrecling the sheet material. The unreeled portion of the sheets are formed in a trouah-shape between adjacent ones of the purlins with the edge portions of the sheets of material positioned Oll the uyper surfaces of the upper flanges of the purlins. The edge portions of adjacent sheets of material are sealed together placing heat insulation material in the troughs of the sheets of material.
Hard sheets of roofing material are placed over the insulation material and purlins. Alternately elongated flexible sheets of material of a width wider than the spaces between adjacent purlins are placed along the lengths of adjacent purlins and over the spaces between adjacent purlins. The sheet material is formed as it is placed on the purlins to locate the edge portions of the sheets of material on the upper surfaces of adjacent purlins to locate the central portion of the sheets of material at a lower level between the purlins. The edge portions of adjacent sheets are sealed together, and insulation material is place-l on thc central portions of the sheet material.
The sheet material can be of varying width but, prefer-ably, is at least wider than the distance between mid-points on the top flanges of adjacent ones of purlins. Thc wider thc sheet material, the further the i8583 ~aterial can hang down between the adjacent purlins rcsulting in a deeper trough and thus a thicker layer of insula-tion can be supported by the trough. The side edges of the flexible sheet material rest on the top surfaces of the upper laterally extending flanges of the adjacent ones of purlins while the center portion of the sheet material sags into the space between the purlins. The flexible sheet material in the disclosed embodiment is supported by a lattice of support straps bclow t]lC
sheet material extending through openings in ~he purlil-c; or resting on the rafters, or by attaching the sheet material at its side edges to the purlins.
In the preferred embodiment of the invention, the outer edges of the sheet material overlap, on the upper laterally extending purlin flanges, the outer edges of similar adjacent sheets extending between the next pair of purlins.
These outer edges are held in place by the fastening of the metal roofing panels to the purlins.
Also taught by this invention is the use of foam board or other solid insulation material to cover insulation gaps created by the metal purlins and the gaps between the purlins between the hanging troughs. Solid insulation material is fastened to the upper and lower flanges of the purlins. The solid insulation board covering the upper laterally extending flanges of the purlins can take the form of a board just wide enough to cover one of the purlins or it can be wide enough to span the space between adjacent purlins. The solid insulation material covering the lower extending flange of the purlin need only be wide enough to cover the flange and possibly any gaps beneath the upper laterally extending flange of the purlin to which it is attached and the flexible sheet material.
Thus the present invention seeks to provide an ,r~
~improved insulated roof stru ~ Qe8 ~e~ein insulation in the form of either loose or batten insulation can be expediently installed in the roof structure in varying desired thicknesses.

Referring now in more detail to the drawings, in which like numerals indicate like parts throughout the several vie-~s, Fig. 2 illustrates the roof structure 9 which includes a plurality of spaced parallel purlins mounted on rafters 18. The purlins 1 each include a central web 2, lower flange 3 and upp~r flan~e 4.
A flexible sheet material 5 is unrolled along the upper flange 4 of adjacent ones of purlins, as shown in Fig. 1. The outer edges 6 of the sheet material are left on the upper laterally extending edyes 4 of the puLlins 1.
The elongate center portion of the sheet material sags down between the central web 2 of adjacent ones of purlins 1, thus forming a trough 7~ The trough is filled ~ith insulation material 8, loose or batten. If batt or blanket-type insulation 8 is used, the shape of the structure is more flat, as shown in the drawillgs~ If loose insulation is used, a more sagging appearance is created in the strips of flexible sheet material 5, but a more stiff 2Q sheet material 5 tends to provide a more unifolm appearance. Abutting edges 6 of adjacent sheets of flexible material 5 overlap one another on top of the upper flange 4 of purlins 1 as shown in Fig. 2 at 10 an~ aee held in place by the fastening of metal roof panel 12 to the upper flange 4 of purlin 1. Preferably, the overlapping edge- portions of -the strips of sheet material 5 are connected together as by adhesive or by heat sealing, depending on the characteristics of the material, the climate conditions and working conditions. This provides an effective vapor barrier beneath the hard roofing material.
lattice of support straps or banding is formed .
5~3 in the roof structure, with the lattice comprising cross straps 11 under tension extencling thro~lclll opel~ s in the central webs 2 of the purlins 1 and with longitudinal straps 13 extending parallel to the lengtlls of the purlins.
The lattice is used as an aid in supporting the bottom side of the trough 7. The support lattice can be formed from cross straps 11 extending through the pllrlills without the longltudinal straps 13, or the lattice can comprise longitudinal straps 13 res~ing on the ra~ters 18 (Fig. 3).
Figs. 3 and 4 show the use of solid insulation board for insulating the gaps between the insulation troughs 7. The upper flange 4 of purlins 1 can be insulated by placing along the top edge o~ the upper flange 4 a piece of solid insulation board 14 which is only slightly wider than the upper flange 4 itself or, an insulation board 16 can be used which rests on the top side of the upper lateral flange 4 and spans the entire space between adjacent ones of purlins. The underside of the Z0 purlins has a slightly wider gap to insulate and as a result slightly wider or insulation board 16, 17 is used to insulate the gap. If the channel insulation formed by the strips of sheet material 5 rest on a support lattice 11-13 that is mounted on the rafters 18 of the building, flat insulation board 16 (Fig. 3) can be used by directly riviting the insulation boards to the bottom surface of the lower flanges 3 of the purlin. If, however, the channel insulation is supported by the lattice of support straps at a higher elevation (Fig. 4) a channel-shaped board 17 is used with side flanges 20, and additional straps 19 can be placed over the rafters lB to engage the flanges as illustrated, or the straps 13 in the support lattice 11-13 on opposite sides of the purlins can be used (not shown).
The insulation board can be fabricated from various suitable materials ,such as glass reinforced cellular plastic isocyanurate insulation, ' ~s illustrated in ~igs. 1 and Sr the rcel support framework 24 comprises a pair of triangular side frames ~,5 and 26 and lower spacer bars 28, 29 and 30 extending across the bottom of the framework. A reel 31 oE t}le flexible sheet material is supported at the' upper apexes o~ t:he triangular side frames 25 and 26 on support bar 32, and the free end of the sheet material moves from the reel 31 beneath lower spacer bars 29 and 30. Bottom runnecs 34 and 35 are mounted on the bottom of the framework 24 and hold the framework on a pair of adjacent ones of the purlins 1.
- A pair of sheet guides 36 and 38 are slidably mounted on the rear spacer bar 30, and clamps 39 and 40 of the sheet guides are slidably mounted on the bar 30. Set screws 41 allow the clamps 39 and 40 to be attached to tl-e bar 30 at variable positions along the length of the bar. U-shaped guide elements 42 are mounted on the clamps 39 and 40 and project downwardly from the framework into the space between adjacent ones of the purlins- When the framework is pushed along the purlins, the sheet material unrolls from its reel 31, passes beneath the lower spacer bars 29 and 30, and the sheet guides 36 and 38 urge the central ~85~3 i portion of the strip of sheet material down~ rtll~ between the purlins. The side edge portions of the strip of sheet material are therefore guided onto the top surfaces of the upper flanges 4 of the purlins 1.
When the strip of sheet material has been ormed in the manner illustrated in Fig~ 5, by forming a trough between the purlins, the insulation material is then placed in the trough. For example, ]oose insulation can be blown into the troughs, batt insulation can be placed by workers standing on the already installed hard roofing material down into the troughs, or blanket insulation can be fed from reels down into the troughs.
It will be understood that the foregoing relates only to a disclosed embodiment of the present invention, and that numerous changes and modifications may be made therein within the scope of the invention as defined in the following claims.
