7' Claims. .(Cl. 108-26) This invention relates to a roof flashing.
- Among the objects of the invention are toprovide a roof flashing having an improved,'built-in reglet which is so constructed that it does not weaken the parapet wall of the building; to provide a roof flashingconstruction which is bent or kinked in a superior manner along its foot portion to prevent cutting orchafing of the roofing materials; to .provide a flashing construction which is built in such a manner as to permit the application of. the plaster to the parapet wall'before the roofing is laid; to provide a flashing construction that is more readily applicable to a variety of types of building construction; and further, to provide a flashing construction Wherein the counter-flashing is gripped or sealed at a plurality of levels in such a manner that .it is more securely held in its proper operative position. Other objects, advantages and features of invention willhereinafter appear.
. Referring to the accompanying drawing, which illustrates what is at present deemed to be preferred embodiments of the invention,
Fig. 1 is a perspective and sectional view showing a fragment of theparapet and roofof a building with my improved flashing construction applied thereto.
Fig. 2 is a fragmental, vertical sectional detail showing a .form supporting the flashing in position for being built intoa parapet wall.
. Fig. 3 is a vertical, sectional view of a modification. r V
.Fig. 4 is a view-similar to Fig. 3 but shows-a second modification.
Referring in detail to the drawing, and describing, first the form of the invention illustrated in Figs. 1 and 2, the concrete parapet wall It is shown supporting a regletl I, said reglet consisting of a strip of sheet metal'o'f considerable width which'isdoubled over u'ponitself throughout the greater portion of its width, its upper edge portion being directed "backwardly', that is. to say toward'theoutside of the building, thereby form ing the double or two ply flange 12 which is em-' bedded inthe concrete wall I 0.
The double'flange I2 is not, however, the only embedded portion of the 'reglet,for from the front edge of the lower -run of said flange the reglet'has a back run-or sheet portion H which overlies the face of the wall Hi to a considerable verticalextent but at the lower edge terminates in an-embedded foot flange 15 that is directed backwardl-y and downwardly.
"The upper run of the aforesaid reglet topflan'gefil2 is-continueddownwardly to form theregletapron Hi, the counterflashing 20 having an-enclosed upper portion -2l which is-encased-or housed betweensaid apron-l6 and the backsheet l4 an'dis thus gripped insuch-a manneras-tobe held-in place.
-Above its strip 21- the counterflalshing has along its upper edge-a forwardly inclined edge portionor flange 2'3, and-along the lower edge of itssaid-strip "2| the counterflashing-has a backwardlyand downwardly inclined relatively narrow strip '25. The three strips of the counterflashing which have been described 'impartto-its upper 'portionasinuousity corresponding in outline to the shape of the alined reglet strips between which -it is gripped and the -sheet-materlal of which the reglet is :made is of a sufiiciently stifi character to provide for safely keeping in place the counterflashing after the latter has been pushed-upwardlyin'to place between the apron-and back-sheet of the reglet.
Between its lower body portion and its sinuous upper part the counter'flas'hing 20 has a relaupperedge, and a lower horizontal rowof nails 46 passingthrough the run Mf-of said reglet 'just above its basal flange 15.
Properly positioned holes forthe nails "will be punched through the reglet before it is nailed in place onthe form as aforesaid. The lower portion of the regl'et just above its basal flange L-l'5 will 'be nailed down to the formwork as'shown, but thenai-ls t5 of the upper row will be only partly driven in, thus maintaining the flange I 2- along the 'upper edge 0f the attached reglet directed backwardly from the formwork, as shown in Fig. '2'.
The construction of the parapet wall with the reglet--built thereinto is accomplished by construc'tingthe desired horizontal extent of formworkand attached regl'et shown in Fig. '2 said formwork being positioned with the face thereof to which the'reglet is attached in alinement with the vertical plane which deflnesthe inner face of a, length of parapet wall about to be-constructed, itfbe'ing understoodthat suitable outer formwork will be provided-so that the concrete may befilled' in between the two formwork members or sections. After the concrete has been filled in thereby embedding the upper and the lower reglet flange portions, then the body portion of the formwork is forcibly withdrawn and by the use of a chisel or other suitable cutting tool the portions of the nails which project from the set concrete will all be cut off flush with the inner face of the completed wall, so that the completed structure will present the appearance shown in Fig. 1.
It will be seen that the means which have been described for securing the reglet to the wall do not require that any hollow spaces remain in the completed wall, hence the building of the reglet into the wall does not weaken the latter. The double upper flange [2 of the reglet is upwardly inclined hence does not interfere with, packing the concrete into the space subjacent to it. The portions of the nails 45 of the: upper row which remain embedded in the completed wall aid in affording anchorage for the built-in reglet. Each of the lower nails 46 has a double headed portion 46a the section of the nail between and including its two heads affording secure anchorage in the completed wall for the lower part of the reglet.
After the roofing 50, with its upwardly directed marginal portion 5|, has been laid, the lower or counterflashing is-edged upwardly into its operative position as shown in Fig. 1. The reglet apron 16 may be sprung outwardly somewhat to facilitate moving of the counterflashing up into its fully inserted position such insertion of the counterflashing is facilitated by reason of adjacent runsor fiat zones of both sheets of the outer part of the reglet joining each other at obtuse angles.
The double seal or locking members provided by the two opposed sinuous sheet portions of the reglet by its two most abrupt backward bent or interlocking parts'or zones provides a positive means for holding the flashing in place. A definite and fixed amount of lap is also provided to insure protection against wind-driven rains.
Owing to the fact that the main straight run 2!! of the counterflashing is deflected backwardly at 201: to a considerable extent in relation to the counterflashing strip subjacent thereto, its lower edge portion which carries the flange 55 is caused to press firmly backward against the roofing which extends upwardly therebehind. This pressure will take place along the back side of the angle between the body :portion of the counterflashing and its basal flange and will keep rain from being blown upunder the counterflashing, and will also prevent the counterflashing from being blown upwardly or becoming loose.
In Fig. 3 is shown a modification wherein the reglet is of a single ply character throughout its entire length. In this View a brick parapet wall 55a is shown upstanding above the level of the roof 56, and the reglet is shown as consisting of an upper horizontal portion 5'! having a terminal upwardly directed flange 58, the reglet portion 51 resting on top of one of the brick courses 55b and underlying a mortar course 59 within which its flange 58 is embedded. -The apron of this form of the reglet extends downwardly in a generally horizontal direction over the face of the parapet wall, like the reglet shown in Fig. 1 and, together with the counterflashing, being shaped the same, these parts are also lettered in the same manner.
;In orderto facilitate inserting the counterflashing 20 between the outer face of the brick wall and the apron of the reglet due to the rough nature of the brick and mortar particles adheringe thereto, I provide an angular sheet metal part 60. Said part has a horizontally extending flange 6i underlying and fastened in any suitable manner to the portion 51 and a vertically extending flange 62 overlying the front face of the brick wall and extending downwardly to a point adjacent the marginal portion 5! of the roofing.
In Fig. 4 is shown a second modification of the invention wherein also the reglet is of a singleply character. In this view a vertical wooden parapet 15 is shown upstanding above the level of the roof 56 and the reglet is shown as consisting of a metal sheet having an approximately horizontal mid width portion 18 joined at approximately a right angle a vertical upper run 19. The wall 15 abuts against a framework 8| to which the upper reglet run 19 is secured by nails 82. The plaster wall 83 is then built upon the central reglet run 18 thus gripping it between itself and the top of the lower, wooden wall 15.
The depending orapron portion of this reglet and the counterflashing which cooperates with it are like the corresponding parts that have already been described and are therefore. lettered in the same manner.
It should be understood that the present disclosures are for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the subject matter claimed.
What is claimed is:
1. A reglet having a flanged back portion for embedding in a wall, said reglet being provided with an apron depending from the embeddable portion thereof, said apron being provided with vertically spaced backwardly deflected portions joining each other at obtuse angles, and a counterfiashing having deflected portions to match, underlie .and interlock with said deflected portions of said reglet, said counterflashing being upwardly insertable behind said apron into its interlocked relation thereto.
2. The subject matter of claim 1 and, said counterflashing having a forwardly deflected portion and subjacent thereto a backwardly deflected portion to grip the marginal portions of applied sheet roofing, said two portions of said counterflashing extending in a generally downward direction and joining each other at an obtuse angle.
3. The subject matter of claim 1 and, said counterflashing having a forwardly deflected portion and subjacent thereto a backwardly deflected portion having a downwardlyand forwardly'directed foot flange, said two portions of said flashing superjacent to said foot flange joining each other at an obtuse angle.
4. In a flashing construction for the marginal portion of applied sheet roofing, a reglet having a back portion, an anchor flange whereby said reglet is securable to a. parapet wall, said reglet having in its secured position a downwardly extending apron which in its general direction parallels said wall, said apron having a plurality of vertically spaced, rearwardly directed deflected portions, the lowermost of said deflected portions being positioned to rest normally in a detached manner against the face of the parapet wall to which it is attached, and a vertically extending counterflashing having in its upper portion forwardly deflected portions rearwardly interlockable with said deflected portions of said reglet, said counterflashing being insertable upwardly behind said apron into operative position after the reglet has been installed upon a wall.
5. As an article of manufacture, a reglet consisting of upper and lower portions embeddable in a parapet wall and an intermediate depending, portion consisting of an apron and an underlying back sheet each of which has vertically spaced apart, narrow, forwardly directed bends or runs and a wider intervening substantially straight run which is backwardly directed at a less inclination than said runs which are above and below it, said bends and runs of said apron and back sheet fitting approximately into each other, to permit for the insertion of a counterflashing, and a counterfiashing having a plurality of runs similarly contoured to be gripped between said intervening runs of the back sheet and apron of said reglet.
6.
