- '8 Claims. (01. loll-s) The present invention relates to roof construction. 7, i p
The present invention contemplates an improved form of roof construction wherein the roofing material-is inthe form of sheets of insulating material such as wall board. This insulation board provides thermal insulation for the building but it generallyg's of too porous a nature to function as the only roof covering, and hence the invention also contemplates the application of a suitableimpervious coating to the insulating material.
According to the preferred method of laying the roof, the sheets of insulating board of suitable thickness (such as are secured to rafters or purlins in courses overlapping in a manner similar to ordinary shingles. The lower edges of the insulation boards are preferably raised up and spaced from the upper surface of the next lower course. After the insulating board has been securedin place hot asphalt, tar (or other impervious material .of a'nature commonly used for waterproofing) is applied to cover the insulation board and some of this enters the crevices formed between. the courses'of board- While the coating is still fluid, crushed slate, stone or gravel is sprinkled onto the coating. This provides a more pleasing color than the black of the asphalt or tar, andreduces the amount of radiant heat absorbed by the roof.
.Other objects of the present invention relate to an improved roof design which employs metal rafters, and. wooden purlins for supporting the insulation board." These parts may be pre-cut to flt and arranged to be readily secured together.
The accompanying drawings show, for' pur- I poses of illustration, several embodiments of the presentinvention, it being understood that the drawings are illustrative of the invention rather than limiting the same.
In the drawings: Figure l'is a perspective view of a form of rafters and purlins before the application of the roofing board;
Figure 5 is a perspective view of a completed roof;
Figure 6 is a perspective view, of a completed roof employing woodenrafters; and Figures '7 and 8 are views illustrating the seof each course of roof insulating board. Suc
curement of a roof rafter to the framing of an adjacent wall.
Figure 1 shows a form of metal roof plate 52 of channel shaped cross-section and designed for use with interchangeable wall forming units having channel shaped frame members suchas shown at 20, 2i and 24, as shown in my application serial No. 620,997, flled July 6,1932.
Metal rafters 81 rest on the roof plate 52 and are secured in place by angle brackets 86. The rafters are spaced 9. suitable distance, such as that of four of the interchangeable sections. The one rafter is used alone at the ends of the roof while two rafters may be used back to back as shown at the left. These rafters have upwardly bent lugs 80 formed out of the upper flange of ,the channel. Purlins 89 are placed above these lugs and secured within by nails 88' The purlins 89 are spaced apart a distance corresponding with the desired width of exposure boards are indicated at 90 in Figures'3 and 5, They are secured in place by nails 9| and spacers l2.-- The spacers act to hold the lower edge of the upper course away from the surface of the next lower courses will be apparent from Figure 3, After the insulating boards are secured in place, a coating of hot asphalt, tar, or other suitable waterproofing compound is applied. to the same. This coating is preferably-applied by a spraying process which forces some of the material up between the layers of roof covering material. The liquid coating is shown at 93. This coating forms .a uniform impervious covering for the entire roof. and may be used in the valleys as well as 3 absorbed by the roof.
The coating material preferably extends down under the lower courses as indicated at 94. It is received'above a flashing plate 95 secured to the lower purlin and bent up to embrace the coating and form a drip. A drain or eaves trough 98 is placed below the drip as shown.
7 The roof shown in Figure 6 is so far as the in- 50 sula'tion board, coating and'crushed slate, stone. or gravel surfacing, the same as described above. The drawings show such a roof secured to ordinary wooden rafters 91.
Figures 7 and 8 illustrate the securing of as rafter I? to the. vertical members I! employed v in a gable. Bolt like members OI have hooked ends 9! to engage the vertical members 3!. Nuts I" clamp the parts tightly together.
Insulation board suitable for the purposes of the present invention may be manui'actured from the fibres of wood, sugar cane. and the like. Board of this nature is commonly employed in building constructions for purposes of insulation and as a base for plaster.
It is obvious that the invention may be embodied in many forms and constructions, and 1 wish it to be understood that the particular forms shown are but a few of the many forms. Various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.
What is claimed is: v
1. The method of building roofs which consists in securing pieces of insulating board to a suitable,
support and in overlapping, shingle-like relation,
the lower edges of the insulating board being spaced away from the upper surface of the next lower piece of insulation board, applying a coating of impervious material to the exposed portions of the insulation board, and forcing some of said coating material into said space.
2. The method of building roots which consists in securing a lower course of root surfacing material to a roof support. securing a second course of similar material to the support so that a substantial portion of the lower course is exposed. and interposing a spacing member so that the lower edge of said second course is spaced above the upper surface of the first course, and applying hot impervious material to provide an impervious coating over the exposed surfaces and filling said spaces.
3. The method of building roots. which consists insecuringalowercourseofinsulating boardto a roof support and a spacing member substantially midway of theupper surface of the course. securing a second course of insulating board with itslower'edgerestingonthespacingmernberso as to be spaced above the surface of the first course, and applying a hot coating of impervious material over the exposed faces and filling the spaces. v
4. The method of building roots, which consists s in securing a lower course of insulating board to a roof support and a spacing member substantially midway oi the upper surface of the course. securing a second course of insulating board with its lower edge resting on the spacing member so 10 as to be spaced above the surface of the first course, applying a hot coating of impervious material over the exposed faces and filling the spaces. and sprinkling crushed slate onto the hot coating. 7
5. be building roof. a plurality of sheets of insulation board arranged in partially overlapping relation to provide a roof covering of multiple thickness, the lower edge of each board being spaced from the upper face of the next lower board, and a continuous impervious coating extending over the upper faces of the projecting portions of the insulation boards and the lower ends thereoi', and extending under said ends to enter into said spaces.
6. In a building met. a roof covering in the form of a multiple thickness of insulating board whose lower edges are opposite one another and spaced apart, and an impervious coating about the lower edges of each board and entering into 30 thespaoebetweenthemtoclosethespaeeand prevent the entry of water in between the super- 7.Inabuildingroof,aroof coveringinthe form of a multiple thickness of insulating board 35 whose lower edges are opposite one another and spaced apart, an impervious coating about the lower edges of each board and entering into the spacebetweenthemtoclosethespace andpneventtheentryofwaterinbetween the boards,and ame'talfiashingstripabouttheooatingwhichcoverstheloweredgeofthelowerboard.
