F. X. A. KREIL MONOLITHIC HOLLOW CONCRETE WALL CONSTRUCTION Filed Sept. 19, 1927 Sept. 23, 1930.
ATTORNEY' ranas Patented sept. 23, 1930 FRANCIS x. A. xnEII., or ALTADENA, CALIFORNIA MoNoLITnIc HOLLOW CONCRETE-WALL cONsrnucrIoIt Appneatien mea september 1a, 1927. serial ite. 220,363.
c Thisinvention relates to wall constructions and more particularly to forms or cores that may be used in forming a wall to cast spaces thereln for the purpose of lightening the 5 load thereof.
inside pillars, itis often necessary to lighten the load of such wall. Tile and brick have been used to accomplish this end, but due to likelihood of earthquakes, such tile and brick is not satisfactory, whereas concrete walls are acceptable to'avoid dangers that otherwise might arise as a resultof subjecting such wall to tremors due to earth uakes. 1 5 Heretofore, woodenorms have been used to form an air. space in a concrete wall t0 be lightened, but if such form is left in the wall it is likely to swell and crack the wall and if such wooden form or core is withdrawn 20 from the wall likelihood of cracking the wall is also revalent. i
An o ject of my invention is to provide a novel and improved form or c ore for use in constructing a hollow concrete wall and which will be inexpensive, light and not likely toswell if left in the wall and thereby eliminate the objectional feature ,of the use of wooden forms. e
Another object is to provide a novel and 9 improved form or "core 'by means of which concrete walls may be poured at one time from floor to top whereby cold joints may be eliminated which occur in the use of metal forms that nerall ermit ouriny at one time of thegeconcreiepto a dlepth ogf' about three or four feet.
Another object is to provide -a novel fo for creating perfect vacuum spaces in bui' ding walls. .Another object is to provide novel, inexpensive means whereby a concrete wall may be provided with hollow spaces fwithout likelihood of cracking the wall by the means employed in its construction.
Other objects, advantages and features of invention may appear from the accompanying drawing the subjoined detail .andv the appended claims. `The accompanying drawing illustrates the accordance with Inyl invention. In wall constructions of buildings between vform tongue and groove fastening means in invention -in some of the forms I at present deem preferable. t
-Figure 1 is a front elevation of a concrete' wall. constructed with air spaces formed in Parts are broken away to; illustrate interior construction.
Fig. 2 is a horizontal transverse section of the wall shown in Fig. 1. l
Fig. 3 is a fragmental perspective view of 69 a 'form or core constructedJ in accordance with A my invention.
Fig. 4 is a fragmntal perspective view of a modified form of core ,constructed in accordance with my invention.
My `invention comprises the combination Aof a concrete wall A having imbedded therein an inexpensive form or core 1v that 1s adapted to provide in the wall A a perfect vacuum air space a.
The core or form 1 is preferably made of a single sheet of ribbed-metal lath or light gauge sheet metal which is bent intp the desired shape with its meeting edges bent to 76 the form of hooks 2 and 3 that engage with each other to maintain the edges in fixed relation to each other. The 'hooks v2 and'3 are ',bent inward from the outer surface of the The form 1 may be of a length .equal to the distance^ between the fioors band c of the building and may also be of shorter lengths l to extend from the a licor b to the under side of a window d. As shown in Figs, 1-3, the 85 s tilfening members in the form of`channel' irons 4 are secured tothe outside ofthe end walls ofthe form 1 adjacent the corners thereofby means of the 5, which are extended through said end walls `from the inside around the outside of said channel irons and tied together at their ends. .Said channel irons reinforce and stiifenthe form -at ltsI corners. e'
Heavy wire hoops form and secured thereto at suitable distances i 6 are slipped over'the apart., as for example, about eighteen inchesf or twofeet, by means ofthe wires 7 which extend over said hoops through the side and 10o end walls of the form, at the corners thereof,
and are tied together at their ends.
In the modification of my core or form 1 shown in Fig. 4, the stifi'ening members-are. in the form of anglse irons 10 which are substituted for the channel irons 4 and fsaid angle irons are placed over the corners of the form and tied to the ends of the core by tie wires 11, which are extended through the side and -endwalls of the form around said angle Yirons and tied together at their ends.,
In practice, my `form is placed within the usual outside Wall form 12, 'and blocks e space the form 1 from the Wall form 12, and maintains it centrally therein. Concrete 18 is poured within the wall form around form 1 from top to bottom thereon, thus eliminating cold joints between` pourings. The spacing and having its meeting ed wire hoops extending blocks e are withdrawn y as the concrete is poured. The concrete mix may be wet or dry, preferably the consistency of mortar. The seep holes 8 are closed or sealed when the outside lforms are stripped, thus providing a perfect vacuum space throughout the Wall.
I claim:
1. A form for walls, said form com rising a sheet of metal bent into the shapeo the ,form and having its `meeting edges interlocked, and stiifening means secured to th form adjacent the corners' thereof.
2. A form for walls, said form comprising a sheet of metal bent into the shape of the form s interlocked, and reinforcing irons secure to the ends of the form adjacent the corners thereof.
3;- A form for walls, said form comprising a sheet of metal bent into the shape of the form, i stifening members secured to the ends of said form adj acent' the corners thereof, and heavy around the form at suitable distances apart.
v 4. A form for Walls, said form comprising a sheet of metal lath bent into the shape of the form, means holding the edges of said lathA in fixed position, and stiiening means secured to the form adjacent the corners thereof.
5. A form for walls, said form comprising form, and means to secure the channel irons to the form.
7. A form for walls, said form comprising a sheet of metal lath bent into rectangular shape and having its meeting edges secured together,- reinforcing irons at the ends of the form adjacent the corners thereof, and-tie wires for tyingthe irons to the form.
8. A Wall construction of con-crete having thereincores to form air spaces; said cores comprisin a sheet metal lath bent into the shape'of t e core; means closing the top of the cores; seep holes at the bottom of the core adapted to be closed; and said cores having lstiffening members secured to its sides.
9. A core for concrete walls and which comprises a strip of metal lath bent into the shape of the core; means for holding -the edges of said lath in fixed position; stifemng members securedto the sides of said core; heavy wire hoops encircling said core at sultable distances from each other, and 4means closing the top of said core; there being seep holes at the bottom of said core adapted to be closed after drainage.
In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 10th day of September, 1927.
f 'FRANCIS X. A. KREIL.
