RHEINSTEIN 3 SETTING SHOE FOR HOLLOW STRUCTURAL WALL PANEL Filed Feb. 26, 1957 2 Sheets-Sheet 2 l/VVE/W'Of? Alfred Rheinstein ATTORNEYS United States Patent- SE'I TING .SHOE FOR HOLLOW STIiUCTURAL WALL PANEL This invention relates to a wall assembly device, and more particularly to a mounting or setting shoe for joining adjacent hollow pre-cast structural. wallpanel sections. a

It is an object of this invention to provide-an assembly guide for building a structural wall from hollowxprecast panel sections whereby relative movement of the panels is prevented after assembly to provide reinforcement for the wall and to maintain the sections in register during setting of the bonding material.

Another object is to provide such device which ensures the proper'width of vertical joints between adjacent' panel sections. 1

Another object is to provide a setting device of the above character which is of sturdyinflexible unitary design. Y

Briefly this invention involves a setting shoe for span.- ning the adjacent ends of hollow preacastwall panel sections which comprises a flat elongated main body portion having at least one hollow wedge-shaped member withits base centrally mounted on the body portion and with the pointededge of the wedge alignedtransversely relative to the body portion. A vertical flange isprovidecl at each end of the main body portion which has a straight section at its junction with the body portion and .:an outwardly tilted extension-having an inner beveled surface. The wedgealso haslverticalside portions adjoining the main body portion. This configuration defines outwardly flared rectangular recesses between eachwedge and each flange'oneither side of the wedge for receiving the transverse partitions of adjacent wall panel sections.

Fig. 6 is a longitudinal section of a single wedge device inplace between two'adjacent wall sections;

Fig. 7 is a longitudinal section of a double wedge de vice in place between four adjacent wall panel sections. -One embodiment of the invention is shown in Figs. 1 and 2. It is comprised of a setting shoe structure designated generally-by the numeral 10, being channelshaped in longitudinal section (see Fig. 2) and having a fiat elongated web or main body portion 11. At the ends 12, 13 of the main body portion 11 are respective flanges 14, 15 whichhave corresponding straight base portions or sections 16, '17 joined to the main body portion 11 in aperpendicular relation thereto, and longitudinally and outwardly tilted extensions 18, 19 adjoining said straight sections, which. are tapered or beveled toward their outermost ends 20, 21.

Centrally "disposed between the flanges 14, 15 is a hollow wedge-shaped member 22 which has its rectangular base 23 mounted on the top 24 of the main body 1 portion 11 softhat its pointed edge'25 "is transversely disposed with respect .to the main body portion and lies roughly parallel to, and midway between, the outermost ends 20,-"21 of the flanges 14,15. The wedge-shaped member 22'has a transverse generally triangular-shaped hollow'central portion 26 opening on both sides 27, 28. inclined side portions 29, 30 are integrally formed at respective ends 31, 32 to the vertical faces 33, 34 of the rectangular'base 23 and converge upwardly toward a common veitex '35 which forms the so-called pointed edge 250i the wedge member 22. Thus it can be seen that the configuration of the wedge member 22 and the adjacent flange members 14 and 15, define a pair of The invention is generally embodied in one of two alv ternate forms, one form having one wedge and flanges extending upwardly from the main body portion at'either side of the wedge, and the other form having'a'pair of wedges with their bases mounted one on the top'and the other on the underside of the main body portion in opposed relation to one another, and a pair of flanges on either side of the wedges extending above and below the main body portion. The first form is used for merely joining two panel sections to one another, whereas the second form is used for joining four panel sections together, all of which will be described in greater detail hereinafter.

Other objects and features of this inventionwill become apparent in the following specification and claim and in the drawings, in which:

Fig. 1 is a plan view of an embodiment having a single wedge;

Fig. 2 is a longitudinal section taken along lines 2-2 of Fig. 1;

Fig. 3 is a plan View of an embodiment having a pair of wedges;

1 Fig. 4 is a longitudinal section taken along lines 4-4 of Fig. 3;

Fig. 5 is a fragmentary perspective showing a double wedge device in place of two adjacent wall panel sections;

outwardly 'fiared rectangular recesses 36 and 37 at either side-of the wedge member 22. More specifically, the inboard surfaces 38, 39 of the vertical sections 16, 17 respectively of flanges 14,15, and the corresponding vertical faces 33, 34 on the basemember 23 define a pair of transverse rectangular grooves or channels '40 and 41 along the oppositeendportions 42 43 of the web 11. Likewise, the inboard surfaces 44, '45 of. the flange extensions-18, 19 and'the-upper-faces 46, 47 of themclin'ed' side portions 29, 30 provide an outwardly flared I mouth for the respective channels 46, 41 as shown in Fig; 2. I

The above described setting shoe can be integrally formed by either bending, machining, or casting from a suitable metal such as aluminum to provide a lightweight and strong'device; The rectangular recesses 36 and 37, as well as the dimension of the rectangular base 23 of the wedge member22 are all dimensioned so as to snugly receive the transverse partitions of the particular wall panel sections being assembled as will be described in greater detail below.

Another embodiment of the invention is shown in Figs. 3 and4, and isdesignated generally by the number it As shown in Fig. 4, this embodiment has a longitudinal section resembling two devices according to the first embodiment previously described, placed back to back so as to resemble an I-beam having a pair of hollow wedge-shaped members 22 centrally mounted on the web or main body portion 11 in opposed relation to one another. With this duplicate structure, the shape and configuration of the flanges 14, 15 and wedge-shaped members 22 are identical all respects to the first embodiment. However, two pairs of rectangular channels 40,

41 are provided in opposed relation to one another, i.e.

one pair on the top 24 of the main body, portion 11, and

the other directly opposite on the underside 49 thereof. Consequently, it is possible to'join together four ad,-

3 in Figs. 5, 6 and 7. In building a structural wall from a plurality of hollow wall panel sections 50 of a wellknown type, composed of cementitious material pro-cast into sections as shown in Fig. 5 having two opposed panels 51 and 52, inter-connected by transverse, partitions 53, a pair of panel sections are put in place with a pair of their side edges 55, 56 abutting one another so as to register a respective pair of grooves 57, '58 and the side channels '59, 69. Then the setting shoe is put in place across the two panel sections 50 so as to span the adjacent ends thereof. For example, a setting shoe according to they first embodiment having a. single wedge member 22 is placed at the bottom of the two panel sections as shown in Fig. 6 withthe wedge member 22 inserted within the space between the opposed channels S9 and 60 and the bottom portions 61 of the latter transverse partitions 53 resting in the rectangular channels 40, 41 respectively. As a matter of convenience and efiiciency, it may be a preferred practice to place the setting shoe 10 at the desired location prior to positioning the panel sections. The setting shoe may be secured in place to the foundation 62 by any convenient means such as screws or the like (not shown), and thus various purposes. It first provides a means for quickly and easily placing the above type wall panel sections next to one another to bring their respective side edges into proper register so that the respective channels and grooves will be properly aligned with one another. The setting shoe is preferably nonflexible so as to rigidly maintain the correct alignment during the hardening of thebond material. Furthermore, the setting shoe is invisible from the outside and also provides the structural wall with a strengthening member. Being of a lightweight me-tal, it is easily transported to the building site and easily-positioned bythe mason or other workman assembling the wall. In addition, oxidation will not afprovide a means of ensuring the proper location of the panel sections. At the top of the panel sections (see Figs. 5 and 7), if a structural wall is'to be built using another row of panel sections above the first row,- then the second embodiment of the setting shoe is employed.

The device is set in place in roughly the same manner as the one previously described. The bottom wedge 22 (shown in dotted lines in Fig. 5) is placed between the side channels 59, and the web or main body portion 11 of the device spans the adjacent ends with the flanges 14, 15 disposed on the opposite sides of the transverse partitions 53. Thus the wedge 22 on the top,24 of the main body portion 11 is properly positioned with the flanges 14 and 15 to receive panel sections for installation of the next row. The assembly of the two rows of panel sections is shown in Fig. 7, where the upper end portions 63 of the transverse partitions 53 of the bottom row 64 are maintained in their. proper position by the longitudinal channels 49, 41 on the underside 49 of the web 11, and the bottom end portions 61 of the transverse partitions of the upper row 65 are received in the rectangular channels 40, 41 at the top 24 of the web 11.

During such assembly of these wall panel sections 50, bonding material 66, such as mortar or the like is placed in the grooves 57, 58 along the side edges 55, 56. Such bonding material may be either placed within such grooves prior to placing thepanel sections side by side, or maybe inserted after the sections have been put in place. v

Thesetting shoe of the presentinvention thus serves feet the non-ferrous metal to any important degree. In some applications a ferrous metal or other material may be preferred. While. two embodiments of this invention have been shown and described herein, it is to be understood that certain additions and changes can be made to the devices shown without departing from the scope and spirit of this invention.

I claim:

in a structural wall the combination of a plurality of hollow pre-cast structural wall panel sections each having a pair of transverse partitions defining elongated channels along opposite side faces thereof and a hollow center space therebetween all extending through the top and bottom of the panelsection, said panel sections being disposed in a common plane with adjacent sections iri-contact with one another and their respective said channels in register; and setting shoes positioned across contacting ends of adjacent panel sections, said shoes having flat elongated main body portions disposed across said contacting ends, wedge-shaped members having their bases centrally mounted on said body portions with their pointed edges disposed transversely thereto, said wedges being positioned between facing channels of said adjacent panel sections, and flange members at both ends of said body portions vertically disposed in the center spaces of said sections adjacent said transverse partitions, whereby said adjacent. panel sections are permanently maintained in alignment with one another and joining with bonding material is simplified.
