MASON, 0F GREENWICH, CONNECTICUT PIASTRE. BOARD Application-lied March 15, 1926. Serial No. 94.685.
This invention relates to plasterboard, and refers more particularly to a plasterboard built up of felted fibrous material. rlhe preferred embodiment of the invention comf prises va corrugated surface sheet united to a fiat imperforate base sheet.
The plasterboardof the present invention may be used as a plaster-receiving board or as plaster lath, or as a sound deadener between floors,walls, or the like, and for moistureproofing solid frost-transmitting walls such as brick, stone, or the like, upon the inner side of .which plaster'is to be applied.
The board of the present invention possesses, among other properties, the advantage of functioning as insulation against transmission'of both heat and cold in addition to its sound-proong and weather-proofing properties.
The plasterboard may be made in continuous elongated exible sheets and rolled into convenient shipping rolls as asphaltic rooting material is manufactured and rolled for shipment.
The plasterboard of the present invention may be nailed directly to studs, solid Walls, rafters, and the like, and may be used as a lining for refrigerators, cold storage rooms, or the like, to exclude heat and moisture from such enclosures.
In the drawings 4 Fig. l is a face view of a plasterboard manufactured in accordance with the present invention, and 4 f Fig. 2 is a ,cross sectional view taken on the staggered line 2-'4-'2 of Fig. 1.
Referring more in detail to the drawings, l designates as a whole a corrugated surface sheet, and 2 a flat, imperforate basesheet ,which may be united thereto by means of the adhesive 3. This adhesive 3 may simultane- 4ously -function as a waterproofing or mois-` ture-proofing medium, or a moisture-proofing medium may be incorporated directly into the felt. The base sheet 2 may be a sheet tively cheap material, such as chip board or through. The structure may be made in a similar substances, and may be provided with the alternate ribs 4, valleys 5, and ribs 6. The ribs 4 are preferably self-supporting and rectangularly shaped in cross-section, thus obviating the necessity for any reinforcing elements. The area between the exterior side walls of each of the ribs 4 is substantially the same as the Width of these ribs it. Each of the rectangularly shaped ribs 4 may be provided with holes 7 through which the plaster 6a 8 will key, as shown clearly at the right hand side of Fig. 2.
When this built up structure is installed,
the nails will pass through both the corru gated sheet l and base sheet 2 and serve as 65 auxiliary meansto firmly hold the corrugated and flat sheets in contact, in addition to the cementitious material 3.
As a feature of the present invention, to provide a corrugated sheet suitable for plaster as described herein which will be Sulliciently reinforced and of the required stiffness and rigidity, I have conceived the idea of providing ribs 6, preferably rounded in form and of much less width than the ribs 4, in the valley spaces 5 between the exterior side walls of the rectangularly shaped ribs 4. These auxiliary ribs 6 are preferably not provided with holes for keying plaster but serve as reinforcing ribs or areas for the sheet.
The board of the present invention serves as an insulator to prevent the transmissionof heat and, possessing moisture-proofing properties, it prevents frost from passing therecontinuous sheet in much the same manner as roofing material is made, being rolled into convenient form for shipment. The sheet may be severed subsequently into suitable lengths and properly secured to a wall to be plastered.
In addition to acting as a reinforcement, the ribs 6, having a closed surface (that is, not apertured), will provide dead air spaces 9 between these ribs and the flat base sheet. These dead air spaces 9 will effectively function to prevent the transmission of heat and cold through the wall and will also effectively deaden the transmission of sound. By
forming the ribs 4 in substantially rectangu- 100 30 surface only lar sha e and making them self-supporting, I am-ab e to .dispense with anyother supportin or reinforcing elements.
claim as my invention:
5 1. A plasterboard, comsrising a sheet of fibrous-material corru ate to form self-supporting interspaced ri s and alternate channels between said ribs, alternate ribs being rectangularly shaped in cross-section, the im spaces between the exterior walls of the rectangularly shaped ribs being provided with' smaller auxiliaryreinforcingribs, the faces of the rectangularly shaped ribs on the upper s surface only being perforated at intervals w to permit keying of plaster, and a flat base sheet cemented to th lower flat imperferatable faces of the corrugated sheet, said smaller auxiliary reinforcing ribs being of relatively less width than the width of the' en- -20 larged rectangularly shaped ribs. 2. A plasterboard, com rising a sheetof fibrous material corru ated to form se1f-sup porting interspaced ri s and alternate channels between said ribs, 'alternate ribs being 5 rectanlarly shaped in cross-section, the spaces tween the exterior walls of the rec-' tangularly shaped ribs being provided with smaller auxiliary reinforcing ribs, the faces of the rectanllarly shaped ribs on the u per ing perforated at interva 's to permit keying of plaster, and a flat base sheet cemented to the lower flat imperforatable faces of the corrugated sheet, said smaller auxilia reinforcing ribs being of relatively, 3., less wi th than the width of the enlarged rectangularly shaped ribs and presenting a closed surface to orm air spaces between the auxiliary ribs and said base sheet.
3. A plasterboard, com rising a sheet of 4@ brous material corru te to form self-supporting interspaced ri s and alternate channels between said ribs, alternate ribs being rectan ularly shaped 'in cross-section, the
spaces tween the exterior walls of the rec- 45. tangularly shaped ribs being provided with smaller auxiliar imperforate reinforcing ribs, the faces o the rectan larly shaped ribs on the upper surface only bein rforated at intervals to permit keying o plster,
54p and a flat base sheet cemented to the llower at imperforatable faces of the corrugated sheet, said smaller auxiliary reinforcing ribs bein of relatively less width than the width of t e enlarged rectangularly shaped ribs,
55 the area between the exterior side walls of each of the rectangular ribs being substantially the same as the width of said ribs.
