Application filed September 12, 1927.- Serial No. 218,980.
This invention relates to oist hangers, and th sin object is to provide an i1 ioroved type if hanger adapted for use in the construction concrete bui dings, and ofthe same general 3e as that shown in my application for patown cot:
embodying improvements there Another obj out is to provide-an integral or compositehanger formed of sheetxmetal and provided with a U-shaped position for receivingand holding an end of the joist abutting the face of the wall, and an inwardly and upwardly inclined member adapted to beembedded in the concrete a wall and. disposed at such an angle that the wall may properly support the joist and the hanger without undue strain, and providing an ample safety factor.
@ther objects will appear as the description progresses.
I have shown a preferred embodiment of my invention in the accompanying drawings, in which: I 7
Fig. 1 is a perspective view ofa hanger embodying my improvements;
Fig. 2 is a perspective view of a section of concrete wall with. my hanger mounted there-' in and serving as supports for oists.
My improvements consists primarily in the I provision of an integral or composite hanger formed of sheet metal and embodying a U- sl sped hanger properH, having parallel upward y extending sides A and A spaced apart and connected the bottom by a portion B. The sides A. and A have'inwardly and upwardly extending portions a and a, respectively, which may be formed as shown in Fig. 1, or otherwise, for permanently anchoring the hangers in the concrete as shown inllig. 2.
The rear edges Z) and bofthe sides A and A, respectively, are adapted to rest against the front face of the concrete wall VJ, and are arranged to support joists as at J, J, on the bottom 13 and between the sides and A. The upper portion of the hanger is provided with an an 'ularl' dis eosed extension C having a lower end B, which may be welded to the lower edges of the portions a and a at points (Z and cZ, etc., where the hanger is of composite character.
Portion G has a central portion 0 extending upwardly and inwardly into the. wall WV at an acute angle, and is bent upwardly and forwardly at E to form an anchor.
When the hanger H is embodied in the wall shown, it provides a'rigid and firm brackt filed April 30, 1927, Serial Number et support for an end of the joistas atJ, with the oist r sting at 1tsend against the face ofthe wall W. Such a type of hanger may be readily built into the wall'lW during the erection of a building,as shown-in Fig.2, where forms F and F are used for providing the wall recess into whichrthe concrete forthe wall VJ is poured. Y i 'l-he boardsof the forms F are cut awayto provide recesses into which the joists J,J, etc-.,
framed as theiorm's-are erected, so that the ends of the joists will abut the front face of thewall. As the forms are erected studs 'S, S, etc, are arranged on the inner side of the form and carry a plate P on the tops thereon, on which the hangers ll are set, and to winchsaid hangers may be temporarily nailed in one or more openings as at 10 in the bottoms T3 of the hangers, so asto properly position the hangers with respect to the forms of he wall whilethe concrete of the wall is be,-
ing poured. j
lV hen the wall is erected to a point above the plane of the oists J, J, etc, the j oists may be placed in the hangers H and secured therer to by nails inserted through apertures 12, 12 in the sidesA and A. Thus the joists of a building may be set into place as the wall is erected, and the studs S and plates P may be arranged in tiers one upon the other, if the building has more than two floors.
The form of the hangers as shown isparticularly arranged so when the edges 6 and b of the hangers rest a st the completed wall, and theportion C thereof is embedded in the concrete of the wall, the hangers provide a substantially rigid structure which can not be removed from position due to any strain or loads on the oists. 7
Furthermore, the placing of the hangers in the wall does not requireintricate. or complicated framing of the forms and structure necessary for the erection of the wall. Accordingly, a subs antial amount of time and money is saved over other nethods and devices.
It will be understood that while I have shown a pre' rred embodiment of my invention, the same may be modified or changed. within the scope of the'appended olanns with-:
out departing fromthe spirit thereof.
lVhat I claim is: C j 1. A. oist hanger comprising a stirrup having vertically disposed parallel sides, a bottom portion connecting said sides, the inner edges of sides and sa1d bottom port1on adapted to abut the face of a wall, extensions integral with and having their lower edges disposed at right angles to said sides, and an anchor member extended horizontally, thence inclined upwardly and bent forwardly at its end from and secured to said extensions, said extensions and said anchor member adapted to be embedded in the wall, for the purpose described.
2. A joist hanger comprising a U-shaped stirrup having right angularly disposed edge portions adapted to abut the face of and to rest upon seats in a wall, and an anchor member extended horizontally from said stirrup and inclined upwardly and bent forwardly at its inner end whereby when the same embedded in a wall said hanger will be permanently supported, as and forthe purpose described. V
3. A hanger comprising a U-shaped stirrup for receiving a joist, an anchor having an outer horizontal supporting portion permanently secured to the upper portion of said stirrup, and a central portion inclined inwardly and upwardly from the stirrup and bent forwardly at its inner end to form an anchor when the same is embedded in a wall.
l. A joint hanger comprising a U-shaped stirrup having spaced parallel side portions adapted to be disposed edgewise against the face of a wall and a connecting portion for supporting a joist, said sides having their upper portions extended inwardly from the rear edges of the lower portions thereof so to be embedded in a. wall, and an anchor memher having. a horizontal portion connecting the lower edges of the upper portions 01' said sides and bent upwardly and inwardly therefrom at an acute angle and thence forwardly at a point above the upper extremities of said sides, for the purpose described.
