PRECAST MASONRY WALL PANEL AND METHOD OF PRECASTING SAME Filed April 5, 1968 4 Sheets-Sheet 4 INVENTOR MANGUM w. "SLOAN BY TDalL-ul' IL. S ud- G L ATTOR EYS United States Patent 01 ice 3,530,632 Patented Sept. 29, 1970 US. Cl. 52-425 9 Claims ABSTRACT OF THE DISCLOSURE A precast masonry wall panel having a pair of spaced wythes of masonry units bonded together by a concrete core, with each wythe having metal rod reinforcing lattices partially embedded in mortar between the masonry units and projecting into the concrete core. Metal attaching plates are secured to the ends of the concrete core adjacent the side edges of the panel for attachment in a building structure by welding. This wall panel is precast by arranging masonry units in a bed and applying mortar between the masonry units with the reinforcing lattices positioned in the mortar in projecting disposition, and then positioning a pair of these precast wythes in spaced face-to-face relation with concrete therebetween to form the core that bonds, the wythes together and embeds the projecting lattices in the core.

BACKGROUND OF THE INVENTION The present invention relates to precast masonry wall panels and the method of precasting such panels. Pressently, prefabriacted wall panels are generally known and used, primarily for the purpose of expediting construction and minimizing costs in comparison with on-the-job construction. The time and labor savings advantage of prefabricated wall panels is especially significant in masonry construction as inconventient, inefficient, and expensive on-the-job brick or block laying is eliminated. A single wythe precast masonry wall panel can be simply preformed to serve as a non-load bearing veneer, facing or partition panel, but cannot normally serve as a load bearing member, especially when formed from standard brick units. Therefore, the problem has been to obtain a precast masonry wall panel of sufficient strength to serve as a load-bearing member and of a simple construction that can be efficiently and inexpensively preformed.

SUMMARY OF THE INVENTION By the present invention, a precast masonry wall panel is provided with sufficient reinforcement for use of the panel as a load-bearing structural component, rather than as only a non-load-bearing veneer, facing or partition member. Further, the reinforcement is so disposed in the panel that the construction can be varied to suit particular structural and design requirements. Importantly, this reinforced masonry wall panel is precast in a simple and inexpensive manner that provides a complete precast panel requiring no on-the-job construction other than that necessary for securement in the building structure, which is accomplished simply due to features of the panel of the present invention.

Basically, this masonry wall panel comprises a single wythe of masonry units, such as brick, bonded together by mortar with reinforcing means partially embedded in the mortar between the units and projecting from one face of the wythe. This reinforcing means provides the strength for load-bearing use of the panel and the projection of the reinforcing means provides means for attachment of the wythe to a building structure or to other components of the panel. A layer of concrete may be bonded to the face of the wythe with the projection of the reinforcing means embedded therein for further strengthening of the panel and to provide a concrete face on one side of the panel.

Preferably, a pair of such masonry wythes with projecting reinforcing means are combined in spaced relation to form a double wythe panel with a concrete core bonding the wythes together into a composite panel with the reinforcing means projections embedded in the core, or the wythes can be secured together without a core by welding together the reinforcing means projecting from the opposed wythes.

For simplified attachment in a building structure, metal attaching plates are secured to the ends of the concrete layer or core adjacent the side edges of the panel for attachment by welding to corresponding plates of adjacent panels and to metal components of the building structure.

In the preferred embodiments the reinforcing means is a vertically extending metal rod lattice having a pair of spaced rods, one embedded in the mortar between the masonry units and the other spaced from the face of the wythe and with an intermediate metal rod extending sinuously between and secured to the spaced rods.

As further reinforcement, grid means may be embedded in the concrete core between spaced wythes with the spacing of the wythes being sutficient to space the projecting reinforcing means to accommodate the grid means therebetween.

The masonry wall panel is preformed according to the method of the present invention by arranging a plurality of masonry units, such as brick, in a single layer bed, and positioning reinforcing means between the units with a portion of the reinforcing means projecting above the bed while allowing mortar to set between the units to bond the units together and to embed the reinforcing means partially in the mortar. The reinforcing means may be initially positioned either before the mortar is poured or after the mortar is poured but before the mortar sets. This single layer panel may be used directly as a single wythe wall panel or it may be further preformed by applying a layer of concrete on the face of the bed with the projecting reinforcing means bonded therein.

In the preferred embodiment, a pair of these single wythes are precast and then positioned in spaced face-toface relation with the reinforcing means projecting into the space between wythes. Concrete is then allowed to set in the space between wythes to form a core bonding the wythes together and embedding the reinforcing means projections in the core. For further reinforcement, the wythes may be spaced sufficiently to provide a space between the oppositely projecting reinforcing means and reinforcement grid means may be disposed in this space. Alternatively, a double wythe panel can be precast omitting the concrete core by spacing the wythes so that the reinforcing means projecting from one wythe abuts the reinforcing means projecting from the other wythe, and then welding the abutting reinforcing means projections together to form an integral double wythe panel. The aforementioned attaching plates may be included in precasting the single wythe, concrete layer embodiment or the double wythe, concrete core embodiment by positioning the plates prior to setting of the concrete.

Thus, the present invention provides a simple and inexpensive method of precasting masonry wall panels capable of versatile application to form various modified panel constructions.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the preferred embodiment of the present invention illustrated in FIGS. 1-4, the precast masonry wall panel 10 is a double wythe construction. The wythes 12 and 14 are each formed from conventional building bricks arranged in vertical rows with mortar 18 conventionally disposed between the brick 16 and forming a bond therebetween. The wythes 12 and 14 may be of any desirable height and length suitable for use in a particular building structure. For example, the height may be equivalent to the spacing between the foundation and the roof system of a one-story building or equivalent to the height of a one-story increment of a multi-story building, and the lengths may be an even increment of the building length small enough to render the panel readily transportable.

The wythes 12 and 14 are reinforced to provide sufficient strength in the panel for use of the panel as a structural load-bearing building component. In the embodiment illustrated, the reinforcing means is in the form of vertically extending metal rod lattices 20, each consisting of a pair of spaced vertical rods 22 and 24, one rod 22 of the pair being embedded in the mortar 18 between brick and the other rod 24 being spaced inwardly in the panel from the inner face of the wythe in which the lattice is embedded. These spaced rods 22 and 24 are connected by an intermediate rod 26 that extends sinuously between and is secured by welding to the spaced rods. In the embodiment illustrated, the lattices extend substantially the full height of the wythes 12 and 14 and are disposed between the first and second and between the first and second and between the third and fourth vertical rows of brick in a four row wythe construction.

The wythes 12 and 14 of each panel 10 are coextensively positioned in spaced face-to-face relation with the lattices 20 projecting into the space between wythes, which space is filled with a concrete core 28 that bonds the wythes 12 and 14 together and embeds the inwardly spaced rods 24 of the lattices 20 therein. The thickness of the concrete core 28 is sufficient to provide a space between the lattices 20 projecting from opposite wythes for convenient disposition of vertically arranged reinforcement grid means 30 in the space between lattices 20. The grid means 30, as illustrated in FIG. 4, is simply a system of conventional reinforcing rods and can be omitted where not required to provide strengthening.

The concrete core 28 substantially completely fills the space between the opposed wythes 12 and 14, though voids may be provided if desired to reduce the weight and cost of the panel 10 and the composition of the concrete may vary to obtain desired properties. The range of variations in the concrete composition and in the volume of voids, if any, is determined primarily by the particular strength, moisture resistance, thermal insulation, and

acoustical insulation properties desired for a specific use. In this regard, special coating layers may be applied to the inner faces of the wythes and different core compositions used in different areas of the panel to obtain special characteristics.

In the embodiment illustrated, the concrete core 28 also serves as a support for attachment of the precast panel 10 in a building structure, and for this purpose the core fills the space between wythes 12 and 14 at the four corners of the panel for securement thereat of metal attaching plates that consist of a pair of upper attaching plates 32 secured to the upper end of the core 28 adjacent the opposite side edges of the panel 10 and disposed between and substantially flush with the upper surfaces of the wythes 12 and 14, and a pair of lower attaching plates 34 secured to the lower end of the core 28 adjacent the opposite side edges of the panel 10 and extending across the lower surfaces of both wythes 12 and 14 to the outer faces thereof.

Securement of the attaching plates 32 and 34 to the core 28 is enhanced by anchoring members in the form of metal rods 38 welded to the plates and extending into the core with an inner hook configuration that prevents dislodgment of the plates from the core.

The location of the upper attaching plates 32 adjacent the side edges of the panels 10 results in abutment of each upper attaching plate 32 of one panel with a corresponding upper attaching plate 32 of the adjacent panel so that the abutting plates can be welded together, as indicated at 36, in FIGS. 1 and 3, to secure the panels together in a multi-panel wall structure. At corners of the wall structure the upper attaching plate 32 of one panel extends beyond the side edge of its panel for abutment with the corresponding plate 32 of the other corner panel.

The lower attaching plates 34 serve to attach the panels 10 to the building foundation by welding, as seen at 40 in FIGS. 1 and 2, to metal anchoring plates 42 located directly under the lower attaching plates 34 on a foundation footing 44 on which the panels 10 are supported.

A wall structure is built, using the described precast wall panels 10 of this preferred embodiment of the present invention by laying the foundation footing 44 to extend continuously under the wall structure at a width greater than that of the wall panels 10. Anchor bolts 46 are embedded in the footing outwardly of both sides of the intended panel locations and at spacings along the footing 44 equivalent to the length of individual panels. These anchor bolts 46 extend above the surface of the footing 44 for extension through the anchoring plates 42, which are thereby bolted to the footing at locations aligned with the intended locations of the lower attaching plates 34 of the panels. These anchoring plates 42 extend widthwise sufficiently for bolt attachment and extend lengthwise sufficiently for disposition under the lower attaching plates 34 of adjacent panels 10.

A panel 10 is then placed on the footing 44 with a mortar joint 48 between the footing and panel and extending intermediate the anchoring plates 42, and the lower attaching plates 34 are Welded along their exterior edges to the anchoring plates 42. Additional panels are then sequentially erected in a similar manner with adjacent panels secured together by a vertical mortar joint 50 and by welding of the abutting upper attaching plates 32. A roof system 52 may then be erected on top of the panels 10.

The resulting precast panel wall structure requires no further structural support, and due to the reinforcement incorporated in the individual panels it has suflicient strength in itself to serve as a load-bearing wall structure. As a matter of fact, for some purposes sufficient strength is obtained with reinforcing lattices 20 incorporated in only one of the two wythes.

As mentioned heretofore, the concrete core 28 provides desirable properties. However, there may be instances where these properties are not necessary or where the properties of a void between the wythes 12 and 14 are desired, in which case the modification of FIG. 6 is suitable. This coreless precast wall panel 54 is a double wythe construction having wythes 56 and 58 and reinforcing lattices 60 identical to the wythes 12 and 14 and reinforcing lattices 20 of the panel 10 of FIGS. 14, but with the wythes 56 and 58 disposed so that the inner rods 62 of the lattices of one wythe 56 abut the inner rods 64 of the lattices of the other wythe 58 with the abutting rods 62 and 64 welded together, as shown, along their abutment. As there is no core to which attaching plates may be secured, this coreless precast wall panel is secured in a building structure by mortar or other conventional means.

The precast masonry wall panels 10 and 54 of the embodiments of FIGS. 1-4 and'FIG. 5 have brick at both faces, which is desirable in many applications for aesthetic and physical property purposes. There are applications,

however, where brick on one of the faces is not desired or is not necessary. For these applications the precast masonry wall panel of the present invention can be modified accordingly as shown in FIG. 7. This modified panel 66 is a single wythe construction having a wythe 68 with reinforcing lattices 70 identical to the wythes 12 and 14 and lattices 20 of the panel 10 of FIGS. I4, and having a concrete layer 72 similar to the concrete core 28 of the embodiment of FIGS. 14 and providing a concrete surface on one face of the panel 66. This concrete layer 72 is bonded to the brick on the face of the wythe 68 from which the lattices 70 project and is preferably, though not necessarily, of a thickness sufficient to embed completely therein the projecting portions of the lattices 70. The concrete layer 72 also can serve the same purpose as the concrete core 28 of the embodiment of FIGS. l-4 for securement thereto of upper and lower pairs of attaching plates identical to the plates 32 and 34 of the embodiment of FIGS. l-4.

Further, where the properties of a concrete layer are not necessary, the single wythe 68 with reinforcing lattices 70 can serve as a single wythe precast masonry wall panel without a concrete layer. Such a panel can be secured in a building structure by mortar or by mortar and welding of the metal lattices to metal components of the building structure.

All of the described embodiments of the precast masonry wall panel of the present invention are simply and inexpensively preformed by the method of the present invention, wherein the reinforced wythes are first precast individually and then further processed to form one of the illustrated panel embodiments, or used without processing as a simplified panel.

These reinforced individual wythes are preformed as illustrated in FIG. 5 by arranging a plurality of brick 16 in a single layer flat bed 74 with the bed 74 having the dimensions of the desired finished wythe and with the brick arranged in spaced relation in rows corresponding to the vertical rows of the completde wythe. In the embodiment illustrated, the brick are arranged in four rows.

The reinforcing lattices 20 are then placed in the spacings between the first and second and between the second and third rows of brick with the one rod 22 of each lattice 20 well within the space between brick and the other rod 24 parallel to and above the brick. Mortar 18 is then poured in fluid form into all of the spaces between brick, which results in the rods 22 being embedded in the mor tar. While the lattices 20 are retained in position, the

mortar is allowed to set, thereby bonding the brick to- Upon setting of the mortar 18, the brick 16, lattices 20 and mortar 18 become an integral reinforced brick wythe that can be used directly as a precast masonry wall panel or further processed to form one of the illustrated embodiments. As an identical wythe construction can be used in all of the embodiments, the method of the present invention is characterized by versatility as well as simplicity.

To complete the preforming of the wall panel 10 of the embodiment of FIGS. 1-4, a pair of reinforced wythes 12 and 14 formed as described above are disposed in spaced face-to-face relation with the lattices 20 projecting into the space therebetween and with the reinforcement grid means 30, if used, positioned between wythes and between the lattices projecting from opposite wythes. The concrete can be applied by pouring onto a flat wythe and then positioning the other wythe on top of the concrete. Preferably, however, the two wythes are first arranged in erect face-to-face disposition and the concrete poured into the space therebetween. Upon setting, the concrete forms the aforementioned core 28, bonding the wythes together by interface bonding with the brick and by having embedded therein the projections of the lattices 20.

The aforementioned attaching plates 32 and 34 are placed in position either before or after pouring of the concrete, but in either case before the concrete sets.

A modification of this embodiment can be formed by omitting the lattices 20 in the precasting of one of the wythes and otherwise proceeding as described above.

To complete the preforming of the wall panel 54 of the embodiment of FIG. 6, a pair of reinforced wythes 56 and 58 formed as described above are disposed in spaced face-to-face relation with the projecting rods 64 of the lattices 60 of opposed wythes abutting, and then Welding the rods 64 together to form the integral panel 54.

To complete the preforming of the wall panel 66 of the embodiment of FIG. 7, a single reinforced wythe 68 formed as described above is covered on the face from which the lattice projects with concrete poured in fluid form thereon in a thickness sufficient to cover the projections of the lattices 70. Upon setting, the concrete forms the aforementioned layer 72 that is bonded to the brick and has the lattices 70 embedded therein. Attaching identical to the plates 32 and 34 of the embodiment of FIGS. 1-4 may be placed for securement in the concrete layer 72 in the same manner as the plates 32 and 34 are positioned for securement in the concrete core 28 as described above.

The thickness of the concrete layer 72 of the embodiment of FIG. 7 is preferably sufficient to completely embed the projecting lattices 70 therein, although in some cases it may be desirable to limit the thickness so that the lattices 70 project therebeyond to provide convenient means for attaching the panel to a building structure.

From the above it is apparent that the precast masonry wall panel construction and method of precasting of the present invention is adaptable to numerous variations and it is to be understood that other variations and modifications are within the scope of the present invention, which is not intended to be limited to the foregoing detailed description or otherwise, except as defined in the appended claims.
