ROOF FLASHING Filed May 5. 1928 2 Sheets-Shae! 2 Patented May 5, 1931 STATES PATENT OFFICE WALTER- P. BUDD, OF DURHAM, NORTH CAROLINA ROOF FLASHING This invention relates to improvements in roof flashing constructions.

The primary object of this invention is the provision of a practical and economical flashing construction, which embodies a flashing holder which may be built into a brick or concrete parapet wall above the roof as the building is constructed, having an improved flashing apron adapted for detachable assoio ciation with the wall and roofing.

A further object of this invention is the provision of an improved flashing construction particularly well adapted for anchorage in concrete parapet walls and the like,

by means of which flashing may be eiflciently attached in place in an economical man ner, to provide a positive water-seal at the juncture of the roof deck and wall.

Other objects and advantages of this in- '21) vention will be apparent during the course of the following detailed description.

In the accompanying drawings, wherein for the purpose of illustration is shown a preferred form of this invention.

Figure 1 is a perspective view of a metal strip or member which is adapted to be embedded in a concrete parapet or other wall above the roof deck, during the formation thereof, and which has associated therewith means to hold the apron and other roofing flashing.

Figure 2 is a view showing the member of Figure 1 held by the form for the concrete wall, and showing the relation which the same bear-s to the form and wall, prior to the removal of the form.

Figure 3 shows the flashing holder of Figures l and 2 in its relation after the form work for the wall has been removed, and

49 showing the attachment of the apron flashing thereto at an intermediate step.

Figure 4 shows the improved roof flashing in place at the juncture of a concrete wall and roof deck.

Figure 5 is a fragmentary perspective view, partly in section, taken through a part of the flashing holder of Figure 1, showing the construction thereof by means of which the same may be attached to form work, and permit the latter to tear loose therefrom.

Figure 6 is an enlarged sectional view showing the relation in which the flashing holder of Figure l is attached to the form work, so as to enable the latter to tear loose from the flashing holder.

Figure 7 is an inside elevation of the apron attaching flange of the holder of Figure 6, showing more particularly the opening adapted to receive the attaching nail by means of which the holder is secured in place to form work during the construction of the wall.

The improved flashing construction is adapted to be used more particularly at the juncture of parapet walls with roof decks.

To this end, the roof deck F adjacent the wall B, is provided with roof covering material 15, which extends over the deck F and upwardly along the outer face of the wall B, as is shown at 16 in the drawings, to

cover the juncture at the connection of the base of the wall with the roof deck. Ordinary flashing 17 which may be of composition, sheet metal, or other material, is bent in an L-shaped relation at the juncture of the roof deck with the wall, to overlie the roofing material 15 and 16; said ordinary l.shapcd flashing 17 including a portion 18 overlying the roofing 15 on the roof deck, and the upstanding portion 19 along the outer face of the wall overlying the portion 16 of the roofing, as shown in both forms of the invention.

Referring to the sheet metal flashing holder A,adapted to be used in concrete walls; the same comprises a body portion 20 adapted to be embedded in the concrete wall in a hori zontal position. The body 20 is corrugated, preferably longitudinally as shown at 21 in the drawings, in order to strengthen the same. The corrugations extend longitudinally, and in cross section the body 20 of the strip of course has a wavy or grooved appearance. Along the rear margin the body 20 is provided with an upstanding vertical protecting flange 23, which in height approximates an inch, although this may vary. The purpose is to prevent seepage of water along the body and into the wall, and keep moisture above the body. The flange 23, of course, has another function, and that is of providing brace arms for supporting the strip A on the form work during the construction of the wall. To this end, arms 2i are struck from the ma terial ot' the flange 23, the arms 24 being struck longitudinally from the flange 23, along a division line which extends parallol with the upper and lower edges of the flange 23, and the arm 2a is severed at 26, at one end, from the flange, but at the other end it is integrally connected with the flange, and on which end the bracearm 24 is twisted, as shown at 27 in Figure 2 of the drawings, to position the brace arm 24: transverse to the flange 23, and in an upward diagonal and divergent relation with respect to the horizontal body 20.

Along the opposite marginal longitudinal portion of the body 20, an upstanding attaching flange 30 is provided, which is of approximately the same height the flange 23, and at the upoer edge thereof the flange 30 has a depending flange 32 connected therewith, and depending along the outer side of the flange 30, in spaced relation therewith to provide a socket The flange 32 in width about one-half the width oi" the flange 30, and as above mentioned is normally bent transverse in upstanding vertical relation with respect to the body 20. At spaced intervals along the flanges 30 and 32, the same are provided with pairs of aligning openings. These aligning openings consist of a large opening 35 punched or otherwi e termed in the flange 30, and a concentric aligning smaller opening 36 in the flange 32. The flange 32 "from the tree edge 37 thereof, in right angled relation therewith to each oi the openings 36, is split, as shown at 38 in Varions views of the drawings, for a purpose to be subsequently described.

Referring to the manner of. attachment of the holder A in the wall ii. the term work tor receivin the poured con rote is suitably placed. and it includes a board or member ll} placed upon the root to torni and shape the inside surface ot the wall ll. ()n the inside "face ll of this member 40, the flanges E30 and 32 are attached by na s 42, or other appropriate securing elemen t c said nails being driven through the openings 35 and 36, and into the board or member s0, with the head i8 lying against the inside surface of the flan 30. The nails 42 are of such size that the heads L3 are approximately the same diameter, but just slightly more than the diameter of the larger opening 35 in the flange 30. The flanges 30 and are thus secured tightly against the inside surface of the board or member to, in order to position the body 20 of the sheet n etal attaching strip A in a horizontal plane. The brace arm 24 is bent at 27 in the manner above described and positioned in an upwardly sloping relation towards the form 40, above the body 20, and at its free end it is flanged or bent at 46. This end 46 is provided with openings l7 therethrough, "for receiving nails 48, by means of which to attach the arm 2-l at its free end against the form member ll), as illustrated in Figure 2 of the drawings.

he flange 30 is secured at spaced intervals along the length thereof to the form member 40, and the arms 21 are provided at spaced intervals along the strip A and secured as above described in a bracing relation to support the body 20 in a horizontal position on the form L0. The concrete is then poured ito the form, and the entire body 20 and brace arms 24- are covered, and the poured concrete is allowed to harden.

WVhen the wall B is sufliciently hard, the form member 40 is removed, and since the opening 35 is about the same as the head of the nails 42, the heads of the nails may be torn through said openings 'ithout destroying the flange 30, and due to the split 38 running thru the opening 36, the nails may be readily removed from the openings 35, without materially injuring the flange 32. Inasmuch as the flanges 46 of the brace arms 2 perform no function in connection with flashing the root, it does not matter if the renu *al of the form 4.0 tears the flanges 4G. Ordinarily, however, the nails 48 will tear out the flanges 46 without materially injuring the same, and. the flanges 46 may then be bent downwardly over the outer surface of the wall B as shown in Figures 3 and 4c of the drawings. lVhen the form ll) is removed. it will tear the flanges 30 and 32 loose from the face 60 ot' the wall B, into an outstanding relation theretrom, and the flanges 30 and 32 are then transverse in a right angled relation with respect to the wall (30, as illustrated in Figure 3 of the drawings.

After this. however. the apron may be assembled in the space 33 between the flanges 530 and 32.

Referring to the construction of the apron flashing E. the same preferably comprises an elongated body strip 70, which is relatively wide, and the upper edge thereof is provided with a preferably right angled flange 71, which is adapted to lit in the inwardly facing socket 38 between the flanges 80 and 32 ot the holding strip A above described, with the body depending along the wall face 60 and overlapping the ordinary flashing 19 at its lower skirt edge. The body 70 at the lower edge thereof is flanged at 73 in an angled re lation with respect to the plane of the body 70, and after the apron flashing has been assembled in this manner in the socks 33 of the flanges 30 and 32, the said flanges 30 and 32 are bent downwardly in a doubled relation over the body'FO, as shown in Figure 4 of the drawings, to draw the upper end of the apron hing flush against the inside surface of the wall 13, and this holds the apron flashing in a secured relation against the wall and against the upper portion of the ordinary flashing 17, in a positive leak-proof connection at the juncture of the roof with the Wall B.

5 Various changes in the method of attaching the flashing construction, and changes in the shape, size, and arrangement of parts may be made to the forms of invention herein shown and described, without departing frOm,
