i Claim- (ol. 220 3.4)
jIThis invention relates tO'a method of and means for holding electrical outlet boxesiiri their proper positions while concreteis being poured around the outlet boxesfso that the outlet boxes will'not be moved out of their set positions.
'-Theobjectof the invention is to provide a method of and means for fastening an outlet box to a form member so that the outlet box will be maintained in its proper position during the pouring of the concrete.
Another object of the invention is to provide a method of and means for temporarily fastening electrical outlet boxes to concrete form members during the pouring of concrete whereby the correct placement or positioning of the outlet boxes will be facilitated, and wherein the parts can be used Over and over again.
A further object of the invention is to provide a method of and means for temporarily fastening outlet boxes to concrete form members which is extremely simple and inexpensive to utilize.
Other objects and advantages will be apparent during the course of the following description.
In the accompanying drawings forming a part of this application, and in which like numerals are used to designate like parts throughout the same:
Figure 1 is a fragmentary sectional View through a poured concrete structure showing an embedded outlet box fastened to a form member by the fastening means of the present invention;
Figure 2 is a fragmentary front elevational view of the fastening mechanism being used;
Figure 3 is a sectional view taken on the line 3-3 of Figure 1;
Figure 4 is a longitudinal sectional view taken through the back plate.
Referring in detail to the drawings, the numeral I ll designates a conventional form member which may be fabricated of wood, and arranged contiguous to the form member ID is the usual conventional outlet box I I. The outlet box II is provided with an open end and the outlet box II is adapted to be embedded in the concrete I4 for holding the usual electrical fixtures.
The present invention is directed to a method of and means for temporarily fastening the outlet box II to the form member ID, whereby the concrete I4 can be poured, and after the concrete hardens or sets, the outlet box II will be positioned in its proper position. The outlet box II includes a pair of spaced openings I3 that are arranged in the back wall I 2 for a purpose to be later described. Arranged contiguous to the outer surface of the back wall I2 is a back plate I5, Figure 4, and the back plate I5 is provided witha pair of spaced threaded apertures I6. The apertures 16 :in the back plate I5 register with theopenings ,I3 in the back wall I Z of the electrical outlet boxIIg j 'I'he' wooden form member I I! is provided with a. pair. of s a ed ope i s I 7. and. e t g through each of the openings I7 is an elongated bolt I8. Each of the bolts I 8 includes a threaded end I9 that projects through the opening I3 and is arranged in threaded engagement with the aperture I6. A hexagonally-shaped nut 20 is mounted on each of the bolts I8 adjacent the back wall I 2 to insure that the bolt I8 is properly positioned.
Arranged contiguous to the outer surface of the form member III is a bearing plate 2| which is provided with a pair of spaced holes 22, the holes 22 registering with or being aligned with the openings I! in the form member ID. The pair of bolts I8 project through the holes 22 and a wing nut or securing element 23 is arranged in threaded engagement with the outer threaded end 24 of each of the bolts I8 for maintaining the parts in assembled relation.
In use, the form member I0 is drilled Or otherwise provided with the pair of spaced openings I1 and the outlet box II is arranged contiguous to the form member I0. Then, the back plate I5 is positioned contiguous to the rear wall I2 of the outlet box II so that the apertures Ifiin the back plate I5 register with the openings I3 in the back wall I2. Then, the bearing plate 2| is arranged adjacent or contiguous to the outer surface of the form member ID so that its holes 22 register with the openings I1 in the form member I0. Then, the bolts I8 are inserted through the registering holes 22, openings I'I, openings I3, and the threaded ends I9 are arranged in engagement with the threaded apertures I6. Next, the wing nuts 23 are arranged in engagement with the threaded portions 24 of the bolts I8 so that the outlet box I I is securely fastened to the form member ID. Then, the concrete I4 is poured in the usual manner around the outlet box I I so that after the concrete I 4 sets or hardens, the outlet box II will be embedded therein. After the concrete I4 has set, the parts can be removed so that they can be used over and over again. That is, all of the parts except the back plate I5 can be recovered for further use. Thus, after the concrete I4 hardens, the wing nuts 23 are removed from the bolts I8, then the bearing plate 2| is removed, and next the form member ID is disassembled from the concrete I4, and then the bolts I8 can be taken Or removed from engagement with the apertures 16. Thus, there is provided the outlet box H which is correctly positioned and is securely embedded in the concrete mass it. The back plate 15 cannot be recovered for future use, since it is interposed between the back wall 12 of the outlet box and the adjacent portion of the concrete It.
By means of the present invention, it is not necessary to use wires to attempt to hold the outlet box in place while the concrete is being poured. The present invention will insure that the outlet box will not be moved out of place ,by the weight of the concrete or by the action of vibrators, and the cost of straightening boxes and positioning the electrical outlet boxes will be greatly reduced. Further, the outlet box II will have a neat appearance in its finished form.
What is claimed is:
In combination, a concrete form member, an outlet box, a means for temporarily fastening an electrical outlet box to the concrete form member, said outlet box having an open end and including a back wall, the open end of said outlet box being arranged contiguous to said form member, there being a pair of spaced openings in said back wall, a back plate arranged adjacent the outer surface of said back wall and provided with a pair of spaced threaded apertures, a pair of spaced parallel bolts projecting through said form member, through the openings in said back wall and arranged with their inner ends in threaded engagement with said apertures, securing elements arranged in engagement with the outer projecting ends of said bolts, and a bearing plate interposed between said securing elements and said form element, there being a pair of spaced holes in said bearing plate for the projection therethrough of said bolts.
