ATTORNEYS United safes Patent o 2,995,870 REGLET AND COUNTERFLASHING William F. OHanlon, Jr., 8825 Guatemala Ave., Downey, Calif. Filed Apr. 4, 1958, Ser. No. 726,585 3 Claims. (Cl. 50-47) This invention has to do with dashing reglets and counterashing such as used on parapets and other walls surrounding deck and roof areas for the purpose of providing a weather-tight joint between the wall and rooting paper or the like covering the deck or roof area.

In conventional roof construction roofing paper over the roong surface is turned up at its margins to lie against the marginal wall surrounding the roof area. In order to cover the exposed upturned edges of the roofing paper and form a weather-tight joint it is common to provide a reglet or ashing member embedded in the material of the wall (usually concrete or masonry) which subsequently receives a counterashing member which extends down over the upturned roofing paper. While there have been many types of reglets designed and in use, a diiculty lcommon to most such reglets is that they are subject to being lled with concrete at the time the wall is cast making it necessary later to clean out this unwanted material before the counterashing can be installed. In this connection the reglet is nailed to the inside of the wooden form. Subsequently the form is filled with concrete which is vibrated and tamped. In many cases careless workmen allow the tools used for this purpose to strike and damage the reglet. Also, the act of vibrating the concrete itself tends -to cause the concrete to seep through any cracks and ll all voids with the result that the concrete often works between the form wall and the reglet into the groove or channel into which the counterashing is later inserted.

Another contributing factor `to the disadvantages of reglets heretofore used is the fact that in nailing the reglets to the form the reglets are often deformed suiciently to permit the seepage of the concrete between the reglet and the form into the portion of the reglet from which the concrete should be excluded.

An object of the invention is to provide a novel reglet flashing member and counterashing construction which overcomes the above-noted disadvantages of flashing members heretofore used.

A further object of the invention is to provide a novel form of reglet which can be readily nailed to the Wooden form and which, when nailed in place, is designed to prevent concrete gaining access to the counterflashingreceiving portion thereof facing the form.

Another object is to provide a novel relatively rigid reglet designed to withstand the blows of careless workmen in tamping and vibrating the concrete in the form without being damaged. In this connection it is an object to provide a reglet which includes a double-walled construction throughout the portions of the device which normally require protection against damage. i A further object is to provide a novel reglet ashing designed to be nailed to the form which is constructed in a manner to withstand fthe force of a hammer blow without damage or deformation. In this connection it is an object to provide a device having a cell-like or tubular central bridging portion which adds rigidity to the device and provides a unique nailing portion and a portion to which the counterashing can be secured by screws.

A further object is to provide novel means for preventing access of concrete into the counterashing-receiving portion of the device and which may be used for stripping clear any thin sheet of concrete which may overlie the entrance to the reentrant counterashing-receiving 2 channel portion of the device after the forms have been removed.

Still another object is to provide a reglet and counterashing construction wherein the reglet and counterashing are so designed that the counterashing is held under spring tension against the upturned margin of the rooting paper which it covers.

A still further object is to provide a novel modified form of reglet for use with a masonry wall and another for use with a plaster wall.

Referring to the drawing:

FIG. 1 is a fragmentary sectional view showing a reglet ashing member embodying the invention attached to a wooden form member;

FIG. 2 is a fragmentary sectional view showing a roof and parapet or surrounding wall of concrete with the reglet fo FIG. 1 embedded in the wall and a counterflashing associated therewith covering the upturned margin of roofing paper;

FIG. 3 is a sectional w'ew of the reglet of FIG. I showing auxiliary means for preventing ingress of cement into the counterashing-receiving portion of the device;

FIG. 4 is a fragmentary sectional view of a masonry wal-l and modified form of reglet member attached thereto; and

FIG. 5 is a fragmentary sectional view of a stucco or plaster wall and a further modified reglet member attached thereto.

More particularly describing the invention, the reglet ashing shown in FIGS. l, 2 and 3 is particularly designed for incorporation into a cement or concrete wall such as that designated 11 bounding a roof or deck 12 provided with a waterproof multilayer roongpaper or the like 14. The margins of the paper are turned up along the inner side of the wall as indicated at 14'. The reglet flashing of the invent-ion is generally designated by numeral 15 and the counterashing by numeral 16.

In FIG. 1 I `show a wooden board 18 which may be assumed to be one wall of a wooden form in which the concrete wall 11 is cast. The reglet is attached to the form by means of conventional double-headed nails 19. In FIG. 2 the reglet is shown embedded in the concrete of the wall 11 after the form has been removed and a portion of the nail 19 clipped off. In FIG. 2 the counterflashing 16 is shown attached to the reglet.

Referring now in more detail to the construction of the reglet member, this is formed from a single piece of sheet metal, such as galvanized iron, copper, aluminum or the like of a suitable gauge commonly used in. the trade. This sheet metal member is bent or formed to provide an upper mounting flange 20, a downwardly opening, upwardly inclined counterflashing-receiving channel section 21, a central tubular section 22, a lower mounting ange 23, and a downwardly and rearwardly` inclined anchor ange 24.

It should be noted that the elongated stift" body of sheet metal is longitudinally folded and/or bent so that the upper mounting flange 20 is of double-wall thickness with the two walls 20a and 2Gb juxtaposed and connected by a bend 20c. This is also true of the reentrant channel section 21 which has an upper portion formed by walls 21a and 2lb and a lower portion formed by walls 21e and 21d.

The channel section 21 is formed with downwardly diverging walls so that the opening thereinto has a greater cross-sectional area than other portions of the space between the walls. The wall 21e of the channel section extends to a point 26 where it forms an obtuse angle with a lower wall 27. The wall 21d stops short of the bend or fold point 26 and connects with a rearwardly projecting convex or rounded bridging wall 28 which, in conjunction with the lower portion of wall 21e` and upper Patented-Ang. 15, 19.61

' v 2,995,870 f l p 3 portion of wall 27, denes the tubular section 22 through which nails 19 are driven to secure the device to the wooden form. In this connection, the wall 28 may be provided with a plurality of spaced holes 28' for the reception of nails. It'is unnecessary to provide holes in the forward wall portion of the tubular section.

'The wall 27 in conjunction with a continuation thereof, designated 31, forms a mounting flange of yU-shapeincross section into which the lower margin of the wall 28v is received. The three walls thus make up the lower mounting ange which is generally designated by numeral' 23. -A continuation 32 of wall 31 forms the downwarly and rearwardly inclined anchor flange 24.

For use in combination with the reglet 15, I provide a counterflashing 16. This includes an upper marginal portion 35 which is rearwardly inclined and adapted to be vreceived in the space within the channel section 21 of the reglet. lBelow this is a somewhat less inclined mounting section 36 through which metal fastener screws 38 are provided at intervals for securing the counterdashing to the reglet. Beneath the section 36 is a short inclined section 40 and below this is a main section 42 which terminates at its lower margin in an outwardly inclined portion 43.

As appears from FIG. 2, the upturned marginal portions 14' of the rooiingpaper 14 or the like are received between the main body 42 of the counterflashing and the. wall. -It is one of the features of my invention that the angle between the main portion 42 and the portion 35 which is received in the channel section of the reglet, is such that the counterashing must be sprung outwardly in order to install it with the result that it is constantly resiliently urged against the rooting paper. The normal position ofthe counterflashing is shown in broken lines in FIG. 2. Thus the counterashing securely contacts the rooting paper and insures a weathertight joint.

It Vsometimes happens that a thin sheet of the ncr particles of concrete works down between the form wall 18: and the reglet so that when the form is removed this sheet covers the entrance to the channel section. If a exible. rope or coated wire 46 is inserted in the channel section as shown in FIG. 3 before the reglet is nailed to the form, the. wire. may be pulled out readily after the` forms have been removed to clear the opening to the channel section 21.

In FIG. 4 I show a modied form of reglet, designated 50, which is intended for use in connection with a masonry wall, designated 51. This reglet also is formed of sheet metal, and it includes a main channel section 52 formed by the walls 53 and. 54. The wall 53 is continued bya reverse bend 55 to form an inclined wall 56 which terminates in the horizontal wall 57. The latter has a forwardly and upwardly extending anchor liange 58.

Below the channel section 53 the wall 54 merges into a straight section 60 which is substantially vertical, and `this in turn is connected to a rearwardly extending horizontal section 61. The lower portion of the device is formed by a vertical mounting flange 62 formed as a continuation of wall 61.

In the use of the device the counterashing previously shown and described is inserted in the channel section 5,1 and the connterashing; secured in place by means 4 of metal fastener screws which may be made to pass through the wall 60.

In FIG. 5 I show la reglet designed for use in connection with a plaster wall. Here the wall is shown as comprising la plaster coating associated with

wooden members

71 and 72. The `reglet has a channel section 74 `for receiving the counterflashing.` This is made up of an upper wall 75 and a lower Ywall 76. The latter is joined to a lower mounting flange wall 77 which provides for securing the lower end of the device to member 71, as by nails.

The upper portion of the device is bent at 80 and again at 81 to form a double-walled, upwardly projecting mounting flange 82. The rear wall 83 of this isv connected by a bend 84 with an upwardly and rearwardly inclined wall section 85 which terminates above and beyond the channel section 74 in a vertical mounting ange 87. Nails may be used for securing this to the member 73.

In the use of the device the counter-ashing is received in the channel section 74 and is secured in place by screws which may be driven into the member 72.

Although I have shown and described preferred forms of my invention, I contemplate that various modifications and changes may be made therein without departing from the invention, the scope of which is indicated by the following claims.

Iclaim:

l. A flashing reglet comprising an elongated stiff body of sheet metal folded longitudinally to provide along the edges thereof upwardly and downwardly extending masonry wall mounting anges, the intermediate portion of said body extending rearwardly and upwardly from its connection with said anges and providing therebetween a reentrant channel to receive one edge portion of a counterashing between the spaced walls thereof, and an elongated rearwardly projecting tubular wall portion underlying a portion of the lower wall of said channel and connected thereto and to a portion of said downwardly extending flange. in spaced bridging relation to the connection therebetween.

2. The structure as recited in claim l in which said body of sheet metal is folded upon itself to provide a double wall structure, and wherein said tubular wall portion comprises one wall of said double wall structure.

3. The structure as recited in claim 2 in which an end of said double wall structure is rearwardly inclined from said downwardly extending ange to provide a wall anchor, and an end of said tubular wall portion extending between the walls of said downwardly extending flange to provide a triple wall structure adjoining said tubular wall portion.
