WALL-BONDING DEVICE.

Application filed August 13, 1923. Serial No. 657,116.

To all whom it may concern:

Be it known that 1, JAMES H. lVAUGH, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in all-Bonding Devices, of which the following is a specification.

This invention relates more specifically to a device for bonding together the members of a hollow concrete wall.

A main object of the invention is to provide a bonding device designed to be employed in connection with slip forms for bonding the members of a hollow concrete wall together as the wallis poured.

A further object is to provide a bonding device carrying a plurality of bonding members that may be positioned on the opposing faces of a pair of hollow wall members and utilized with a wall slip form during the pouring of the wall members.

A still further object of the invention is to provide a novel concrete wall slip form, in which the wall bonding device constitutes a portion of the form.

Other objects and advantages will be apparent from the following description, reference being had to the accompanying drawing, in which:

Fig. 1 is a plan view of my bonding device illustrated in connection with a slip form mold in operative position on a hollow concrete wall. 7

This invention is designed to be employed in connection with concrete slip forms of the type illustrated in my co-pending application for U. S. Letters Patent entitled Apparatus for constructing concrete walls, S. N. 587,894, filed September 13, 1922.

In the above entitled application the slip form was designed for forming a singlev solid concrete wall, while the form constituting a part of my invention is adapted for the formation of a hollow concrete wall,

the construction being altered to conform to my novel wall bonding device which is employed in conjunction therewith.

Mold walls for forming the hollow wall are arranged in pairs l0, l1, and 12, 13, each pair being spaced apart between which the concrete is poured to form the wall mem bers 1e, 15, the space between the pairs of mold walls being filled with an insulating material, such as ground cork, in the construction of ice houses, or other refrigerating structures. lValls 11, 12, are rigidly connected together by means of longitudinally extending beams 16, 17, 18, spaced apart, whilethe outer faces of mold walls 10, and 13, have similar beams 19, 20, 21, secured thereto. Bolted or otherwise secured to the outer faces of beams 19, 20, 21, are a plurality of vertically extending beams 22, 23, spaced apart a suitabledis tance, the upper ends of said beams extending upwardly beyond the upper edge of the mold walls and each oppositely disposed pair are tied together with laterally extending timbers 24, 25, spaced apart. Disposed upon the upper edges of the mold walls are a number of transversely extending beams 26 spaced apart and their ends extending beyond the outer faces of vertically extending beams 22, 23, a suitable distance to form a support for a platform flooring 27 for the workmen. Inclined braces 28 are provided to tie beams 26, to the lower end of beams 22, 23. A. railing 29 is secured along the outer edges of the platforms to insure the safety of the workmen, during the construction of the hollow wall.

Mounted in the foundation 30 of the hollow wall are a plurality of vertically disposed reinforcing rods 31, 32, the rods ex tending upwardly through each wall member to approximately slightly greater than the entire height of the finished wall, and which for convenience in the handling may be formed in sectional lengths. The rods pass through exteriorly threaded sleeves 33, 34, mounted in threaded bearing blocks 36, secured between the cross timbers 2%,

25, secured, to the upper ends of the vertical beams 22. 23, of the slip form. The lower ends of sleeves 33, 34, beanagainst blocks 37, 38, capable of being rigidly secured to each of the rods 31, 32, and their upper ends are each provided with a toothed wheel 39, for rotating the sleeves to eievate the form as the work progresses. In order to strengthen the form construction, vertically disposed tie rods 40, are secured between beams 19 and blocks 11 mounted between the cross timbers 21-, 25, and a plurality of vertical tie rods 43 are secured between beams 16, 18, and cross bars at secured to the top of the form walls and spaced apart as clearly shown in Fig. 1 of the drawings.

The improved bending device preferably consists of a plurality of pairs of vertically disposed timbers or wood strips 4:5, 4:6, approximately 1" X 3". Hounted in each pair of timbers 45, 46, are a plurality of wall bonding rods 48, which pass through aper tures 19 formed in the timbers, their ends terminating beyond the outer faces of the timbers -15, 46, and the vertically disposed rods 31, 32, as clearly shown in Figs. 2 and 3 of the drawings. The ends of bonding rods 18 are upturned as at 50, and horizontally disposed reinforcing rods 51 are mounted on the cross rods, the upturned ends of said cross rods preventing a displacement while pouring the concrete.

The timbers or wood strips carrying the bonding rods 48 are disposed against the opposite faces of the Wall members and spaced apart a suitable distance as shown in Fig. 1 of the drawings.

In order that the bonding devices will not interfere with the operation of the slip forms, each of the inner oppositely disposed mold walls 11, 12, are provided with a plurality of vertically disposed slots or openings 55, of approximately the same width as the wood stJips it-5 carrying the bonding rode, the strips chambering in the openings formed in the mold walls. By means of the above construction it will be noted that the bonding devices may be placed in position before work .on the wall is commenced, the vertical rods 31, 32', and the horizontally disposed bonding rods 51 maintaining the devices in proper spaced relation, as the Work proceeds. As the strips carrying the bonding rods completely fill the slots formed in the mold walls, no leakage of the wet concrete will occur during the pouring operation.

In the operation of my bonding devices the slip forms are placed over the concrete foundations 60, and then the plurality of pairs of bonding devices are placed in the slots formed in the mold walls 11 and 12. The vertical reinforcing rods 31 being in position the horizontal reinforcing rods 51 are placed on the upturned ends of the bonding rods 48, as clearly shown in Fig. 3 of the drawings. As the wall members of the hollow wall are poured it will be seen that the bonding devices will securely bond the memhere together. After the poured portion of the members has set a sufficient time the slip form is moved upwardly by means of the toothed wheels The above operation is continued until the wall is completely linished, the slots in the side walls 11 and 12 permitting an up ard movement of the slip form without interfering in the slightest with the bonding device, and moreover as the wood strips 45 completely fill the slots formed in the side walls 11 and 12, no leakage of the wet concrete from the slip form will occur.

From the above description it will be noted that I have provided a novel form of bending device which may be effectively used in connection with concrete slip forms, and furthermore it may be used advantageously with stationary concrete forms.

As the strips 15 are thin, they may be left against the inner faces of the wall member or they may be removed therefrom without disturbing the bonding rods l8, saw slots 62 being formed in side strips from one side te each of the apertures.

What I claim is- 1. In a bonding device for hollow concrete walls, a plurality of vertically disposed wooden strips arranged in oppositely disposed pairs and spaced apart, and a plurality of bonding rods connected to each pair of said wooden strips, the ends of said rods projecting beyond the outer faces of said strips, the pairs of wooden strips being removable from the bonding rods after the formation of the hollow wall members.

In combination with concrete slip forms for forming hollow concrete wall members, said forms being provided in their oppositely disposed walls with a plurality of vertically disposed slots, of a plurality of elongated members arranged in pairs each pair being oppositely disposed and provided with a plurality of transversely disposed bonding members secured thereto, said elongated members being disposed in the slots formed in the mold walls of said mold forms, the ends of the bonding members projecting into the mold. forms, whereby the operation of the slip form will not interfere with the bonding members, and means to move said slip forms.

3. The combination of a hollow concrete wall molding form of the slip form type, having slots in the oppositely disposed walls of the mold wall members, of a plurality of metallic bonding members, and means to support the same in position, said bonding members extending into the mold cavities of the mold wall members, and the supporting means disposed in the slots formed in the walls of the mold members.
