RUBBERIZED BITUMINOUS SEALING JOINT Albert C. Fischer, Chicago, Ill.; Wallace C. Fischer and Cecile G. Fischer, executors of said Albert C. Fischer, deceased, assignors to Servicised Products Corporation, a corporation of Illinois Application April 4, 1945, Serial No. 586,479
(Cl. S-7) 3 Claims.
A 'I'his invention relates to rubberized bituminous sealing joints and particularly to such joints for rooiing sheets and analogous structural sheets.
It is the object of the present invention. to provide a lasting joint between adjoining sheets of roong material which remains effective under all temperature conditions in both extremely hot and cold weather.
It is a further object of the invention to provide a sealing joint for roong sheets which may be supplemented by the integration of roofing nails which are self-sealing, so that no penetration of moisture into the joint ever takes place.
It is a further object of the invention to provide self-sealing rooing` sheets which seal any ruptures or breaks in the rooiing sheets occasioned by undue expansion, impacts or other disturbances.
It is a further object of the invention to provide a laminated structural unit exemplified by roofing sheets or built-up roofing, waterprooiing sheets, concrete curing sheets and the like, in which at least one of the laminations consists of tacky and adhesive rubberized bituminous material which serves to heal and seal any breaks in the felt or paper layers of the sheet material.
Other objects and purposes will appear from the following detailed description of the invention, taken in commotion with the accompanying drawings, wherein Fis. 1 is a vertical sectional view of a roofing joint embodying rubberized bituminous lap cement coating;
Fig. 2 is a vertical sectional view showing the rooting joint embodying a lap cement coating of rubberized bituminous material which is supplemented by fastening nails;
Fig. 3 is a vertical sectional view of a roong nail coated with tacky adhesive rubberized bituminous material which seals more completely the opening in the joint whereat the nail is applied;
Fig. 4 is a vertical sectional view of a sheet Y of structural material embodying a coating of rubberized bituminous material which is selfhealing;
Fig. 5 is a vertical sectional view of a multiply structural sheet material having a plurality of laminations of paper or fabric covered with layers of rubberized bituminous material to effectuate a sealing of the composite sheet upon the occurrence oi a break in any one of the lamina;
Fig. 6 is a vertical sectional view of a laminated structural sheet which may be a roofing sheet embodyingI an intermediate rubberized layer between sheets oi rooting paper or fabric, and
Figs. 'I to 9 illustrate variations of rooiing arrangements of that shown in Figs. 1 to 3.
Fig. l shows a roofing joint embodying sheets .l and 2 `of roofing paper. or cloth of conventional construction, in which the lap joint between them is made by the application of a coating of rubberized bituminous material 3, at the junction between the ends of the sheet. The use of this specific material in lieu of conventional lap cement results in a lasting joint which remains effective under all adverse conditions including sub-freezing temperatures as low as 10 F. The application of this material is also a simple procedure, since the same is applied as a coating or paint and not as a cut-back material for the purpose of dissolving any of the asphaltic material on the rooting sheets i and 2. The `joint becomes adherent immediately and remains so even when sheets I and 2 move relatively to one another as a result of variations in temperature.
. The sealing joint with the rubberized bituminous material may be supplemented by the penetration of roofing nails or tacks 4 into the roong stud B as` shown in Fig. 2. The rubberized biv tuminous material surrounds the nail closely and in eect acts as a self-sealing puncture in a tire, in which case the sealingcomposition becomes localized at the opening to effect a closing thereof. This self-sealing function may be further supplemented by the use of nails 5 having at least the Shanks 6 thereof coated with rubberized bituminous material of rubberized-bituminous nature. This assures a copious supply of sealing medium at the point where penetration of moisture into the joint is most likely to occur.
The rubberized bituminous mixture used in the making of the joint under consideration is oi a tacky adhesive character having a great degree of distendability and recuperative power.
The composition may consist of about 31/2% to 5% of rubber, 35% of a hard brittle asphalt having a melting point of about 170 F. to 180 1/, to 1% of a plasticizing agent, about 40% of a soft asphalt having a ilow point of about F., 5% to 7% of a mineral ller and 1% to 3% of a flow retarder.
The composition may have a polymerized linseed oil in lieu of the rubber constituent.
A suitable composition is as follows:
Reclaimed rubber 17.5% Flux oil (residual 011)-.. 3.8% (1% to 10.0%) Polymerized coumarone- 1.5% (1% to 5.0%) Synthetic rubber 4.7% (2% to 10.0%) Hydrocarbon oil (S. V.
superior base) 20.0% (13% to 23.0%) Resin '1.5% (2% to 12.0%) Asphalt 45.0% (40% to 50.0%)
The rubberized bituminous coating composition is also useful in roofing sheets and analogous sheet materials used in diierent locales other than sealing joints, yby virtue of the flowing characteristic of the material which is effective in sealing ruptures and breaks in the sheet material of which the same forms a part. The use of rubberized bituminous material in such sheets is illustrated in Figs. 4 to 6.
Fig. 4 shows a layer of rubberized bituminous material superposed upon a layer of paper or fabric which normally can'be used as a structural sheet for rooilng purposes, waterproong material, concrete curing sheets or other miscellaneous construction purposes. Upon the occurrence of a rupture or break II* in the sheet of fabric or paper II, as a result of stretching of the latter sheet, or external impacts, the sheet I retains its integrity and flows into the rupture il' to mend the break in the sheet so the function thereof can be carried on.
Fis. 5 shows a laminated sheet construction formed of multiple layers I3 of paper or fabric alternating with layers I2 ci rubberized bituminous material which are self-sustaining and 5 which accommodate themselves to the irregularities or breaks I3 to render them self-healing.V
In the constructional form of the invention shown in Fig. 6, the layer of rubberized bituminous material Il forms an intermediate ply between the layers I5 oi fabric or paper to mend any breaks which may occur in either one or both of these sheets.
Fig. 'I illustrates an arrangement wherein the sheet of roofing felt I8 is applied to the rooiing planks Il by means of nails 5 and the adjacent sheet of roofing felt is lapped over the edge o! the sheet I8 and is adhesively applied thereto by a layer of rubberized bituminous material I9. In view of the fact that the overlapped edge of the sheet 20 is in engagement with the underlying sheet I8 by means of the adhesive layer of rubberized bituminous material I9 only, the sheet 20 is free to move relatively to sheet I8 without hindrance of any attaching nails.
The use of the Vrubberized bituinino` rial which is more-distendable than rubber, particularly 1n its scanned state, and is adhesive v under all temperature conditions, makes possible the eiectivesealing of joints and unintentional ruptures in sheet materialso that effective seals are had for unlimited periods of time.
The rubberized bituminous material may be applied to one or both overlapping portions of the sealing joint for roofing sheets. The layers of the rubberized bituminous composition in thelaminated sheet constructions may be applied by any suitable coating procedures known inthe art of laminating fabrics and other sheets.
This application is a continuation-impart of my application Serial No. 576,461, iiled February 6, 1945, now abandoned.
I claim:
1. A lap joint for roofing sheets embodying a layer of rubberized bituminous oil composition between overlapping portions of said sheets, said composition comprising rubber. flux oil and asphalt, and being tacky, adhesive and highly distensible at varying degrees of temperature,
