Original application December 5, 1942, Serial No. 467,971. Divided and this application October 16, 1947, Serial No. 780,272

1 Claim.

This invention relates to methods of constructing walls, and is particularly well adapted, altho not limited to use in the construction of the outside walls of buildings.

The present application is a division of an application filed by me December 5, 1942, Serial No. 467,971, disclosing Molding Apparatus for forming Buildings, which has since matured in Patent No. 2,434,708, on January 20, 1948.

The principal object of the invention is to provide a method of constructing buildings whereby the hollow walls, with both vertical and horizontal air spaces, may be progressively formed with footings upwardly of an integral mass of concrete or like cementitous material, the vertical spaces being in communication with horizontal spaces formed by tubes of any suitable material as metal, clay or composition of sufficient strength to sustain the superimposed load of concrete or Vthe like, until it has set. These tubes are preferably disposed in their desired positions before the concrete sets and arranged in vertically spaced relation with concrete surrounding the circumference of each tube, held against lateral displacement by suitable forms and collapsible cores, which may be progressively placed as the wall is built to the desired height.

Other objects and advantages of the invention will appear in the following detailed description, taken drawings, forming a part of this specification, and in which drawings:

Fig. 1 is a vertical cross sectional view thru, a suitable footing providing with suitable anchor members or bolts, reinforcement anchors and guide stubs extending upwardly from the top thereof.

Fig, 2 is a view partly in plan, showing the footing on a reduced scale, and partly in horizontal section thru suitable molding apparatus which may be used in practicing this method, the tubes for horizontal air spaces also being shown in plan.

Fig. 3 is a vertical, cross sectional view thru the footing and showing the tubes and collapsible 'cores in elevation, together with suitable means for supporting theA tubes, .a portion of the view being broken away to condensethe same.

Fig. 4, is a side elevation of the wall form, a portion being broken away to condense the view.

Fig. 5 is a fragmentary, vertical, cross sectional view similar to the lower vportion of Fig. 3, but showing concrete in place between the wall form and surrounding the tubes.

Fig. 6 is a fragmentary, horizontal sectional in connection with the accompanying view of a finished wall portion and showing a vertical void and communicating horizontal voids. Fig. 7 is a vertical, longitudinal sectional view thru the wall at the vertical voids and axes of the tubes, a portion of the view being broken away to condense the view.

The preferred rst step in the method is to provide a footing 60 of concrete having embedded therein suitably spaced form anchor members 18, such as bolts; reinforcement anchors 8|); and, guide stubs 8|, which extend upwardly from the top surface of the footing as shown in Fig. l. The form anchor members i3 are spaced apart one from another longitudinally of the footing along lines adjacent its inner and outer sides so as to detachably secure spaced wall material confining forms to the footing as shown in Fig. 2. These forms may comprise spaced vertical channel members |3|, and metallic flanged mold panels |35, of the character shown in my aforesaid Patent 2,434,708, it sufcing to state that, in the example shown the bolts extend thru foot anges 8 of the channel members ISI, and bottom anges 9 of the'lowermost panels |35, and receive nuts l0 to hold these forms in place.

Likewise the guide stubs 8| are disposed 'in groups spaced apart one from another longitudinally of the footing Ell, each group comprising a plurality of stubs in lines inwardly of the lines of fo-rm anchor members 13, so as to hold suitable, vertically disposed core forms 83 against lateral displacement, between the form members |3| and |35, as shown in Figs. 2 and 3. These core forms 83 are preferably of the collapsible type an example of which is shown in my covpending application for patent on collapsible Ywall forms and cores. In the example shown the Vapparatus 99 comprises a plurality of vertically spaced rods 274, arranged in pairs, a plurality oi' tubes 215 arranged between the rods of each pair, and means 216 engaging the rods and tubes for securing the latter in the vdesired position against displacement as cementitious material is poured into the cavity between the wall forms and about the collapsible cores, reinforcing rods and tubes.

Suitable ties 211 of wire or the like may be used to secure the lower portions of the rods 21d to the reinforcement anchors 89, and a suitable steadying bar 218 is also disclosed in Fig. 3 to temporarily hold the rods at their upper ends against displacement.

The rods 214 may be of any suitable cross section with one rod of each pair adjacent to and spaced from one of the upright wall forms, and the other adjacent to and spaced from the other upright wall form as shown in Figure 2. The tie 211 may lbe wire wrapped around the lower end of the rod and its adjacent reinforcement anchor 80. The upper ends of the rods may extend thru holes 219 in the bar 218, which is temporarily secured to one of the wall forms as by bolt 239.

The tubes 215 may be of any suitable, inexpensive material capable of withstanding the pressure of the superimposed load of concrete, until it has become set. It is preferred to use tubes which may be cut from tubular stocks, with a saw, or other suitable instrument, to the desired length and, to have the open ends of th-e tubes in planes perpendicular to the axes of the tubes. However, these tubes may be of molded material, such as clay, of the desired length, or of sheet metal formed into tubes. tubes abut against the collapsible core forms 83 as shown in Fig. 2 so they are temporarily closed against ingress of cementitious material while the wall is being poured and until the collapsible core forms are removed.

The means 216 may comprise wires arranged crosswise of the reinforcing rods, above and below the tubes 215 and having their end portions 281 wrapped around the reinforcing rods, but this is merely by way of example, since any suitable means may be provided for this purpose.

In carrying out the method, the footing Bil iS formed with the anchor members or fbolts 13, the reinforcement anchors 89 and the guide stubs 8l in place, In locating these projecting elements 13, 85 and Si care is exercised so as to have the longitudinal rows of anchor members 5S spaced apart the correct distance so that when the -V spaced wall material confining forms |31 and |35 are placed, a wall of the desired thickness may be produced. The guide stubs Si arealso accurately located so that they may removably retain the core forms in proper position, which may be arranged either in engaging pairs or isolated in spaced apart relation one to another, as shown in Fig. .2. The reinforcement anchors need not be so accurately located as to distance between the core forms, but should be spaced the desired distance from the wall forms E31 and 135 so as to locate the tub-es .215 preferably midway between the outer faces of the finished wall.

With the footing thus formed having the elements 19, Se and el in proper location, the collapsible core forms, tubes with their reinforcement and in end abutting relationship with the core forms, and the spaced wall material confining forms may be placed, either progressively as cementitious material l2 is poured between the wall forms and extending exteriorly of the core forms and tubes, or the collapsible core forms and tubes in the relationship described, as well as the spaced wall material confining forms may all be placed for the formation of the entire height of wall before pouring of the cementitious material. After the latter has set, the collapsible The open ends of the core forms 83 are removed, with a resulting wall having the characteristics such as may be 0bserved in Figs. 5, 6 and 7.

It will be noted that, by this method, while the collapsible core forms are removed and hence form no part of the finished wall, the guide stubs 8| used in retaining these collapsible cores in place while the mass of cementitious material is being poured and until it has set, remain embedded in the footing and wall and subsequently serve to assist in anchoring the wall to the previously formed footing and particularly against lateral movement of the wall with respect to the footing. This anchoring of the wall to the footing by the guide stubs 8l takes place adjacent the vertical voids 63, at zones of the wall where the cross sectional area of cementitious material is less than at zones of the wall where the horizontal voids 64 are located. However the wall is anchored to the footing at the last mentioned zones by the reinforcing anchors all, associated with the tubes 215.

I claim:

In the method of constructing a poured concrete wall having a footing, and horizontal and vertical communicating voids, those steps which consist of forming a footing having embedded therein upwardly projecting form anchor members spac-ed apart from one another longitudinally of the footing along lines adjacent its inner and outer sides, upwardly projecting guide stubs disposed in groups spaced apart longitudinally of the footing, each group comprising a plurality of stubs in lines inwardly of the said lines of anchor members, and upwardly projecting reinforcing anchors disposed in groups between said groups of guide stubs each group of reinforcing anchors comprising a plurality i anchors in lines inwardly of the said lines of guide stubs; setting in place between the stubs of each of said groups of guide stubs, a removable vertically disposed core form for forming a vertical void in the wall; securing to the anchors -ofeach of said groups of reinforcing anchors, apparatus for forming horizontal voids in the wall, including tubes in endwise abutting relation with said removable core forms; detachably securing spaced wall material conning forms to said form anchor members; lling the spacebetween said wall material forms, cores and tubes upwardly from said footing with concrete, embedding said guide stubs and reinforcing anchors in the mass of concrete; and, removing said core forms after the concrete has set so as to open the ends of said tubes to the vertical voids formed by said core formsand leave the wall tied to the footing at the zones of the vertical voids by said guide stubs.
