Description

BACKGROUND

Manufactured stone and brick products have gained popularity in the housing industry because of their light weight, variety of style options, ease of installation and relatively inexpensive cost. In general, such products are produced using specialized dyed concrete. The color of the products may be varied to provide a variety of style options to consumers. During manufacturing, partially cured products are removed from molds and stacked into ovens for further curing. More specifically, de-molded products are loaded onto wooden pallets, the wooden pallets are loaded onto skids, and the skids are loaded into the ovens. After further curing, the products are removed from the ovens and pallets, and packaged in boxes for shipping. The time and labor necessary to load the products onto drying racks, unload the products and package the products for shipping is costly. Additionally, if the stones are packaged for shipping before being fully cured, the shipping boxes prevent air from circulating around the products and heat generated from further curing may cause condensation to appear on the surface of the products, thereby affecting the color of the stone or brick and creating unsightly staining.

SUMMARY

The present invention is directed to methods and packages for curing and shipping manufactured masonry panels. The package may include groups of manufactured masonry panels retained between sets of spaced slotted rails. In use, the multiple sets of masonry panels are retained between first and second sets of slotted rails with pairs of the masonry panels being retained back-to-back and air flow channels being established between both main body portions and manufactured facial portions of the masonry panels, allowing for further curing of the masonry panels. The masonry panels can be stacked between sets of slotted rails until the desired package size is obtained.
In one embodiment of the invention, each masonry panel includes a main body panel having first and second rows of manufactured stone or brick extending therefrom and a securing bracket extending from a top portion of the main body panel. In use, a set of the masonry panels is inserted into upper slots formed in the top wall of each of a set of spaced slotted rails such that a bottom portion of each masonry panel is retained by the first set of slotted rails. A second set of spaced slotted rails is lowered over the masonry panels and the securing brackets extending from the masonry panels are inserted into lower slots formed in the bottom wall of each of the second set of spaced slotted rails such that the securing brackets are retained by the second set of slotted rails. In this manner, groups of masonry panels can be stacked between sets of slotted rails until the desired height and width of the package is obtained. Optionally, one or more braces may be secured to the package for added stability during transport.
The first and second sets of slotted rails securely retain masonry panels there between such that air flow channels are defined between the main body portions and the manufactured stone or brick of the masonry panels. With this configuration, partially cured manufactured stone or brick can be packaged before being fully cured, and may be further cured within the package without detrimental effects to the appearance of the manufactured stone or brick. Further, oven drying of the package is not necessary and, therefore, no curing oven need be utilized.

With initial reference to FIG. 1, a pallet 10 carries a curing and shipping package 12 of stacked manufactured brick or masonry panels 14 in accordance with the present invention. More specifically, a plurality of masonry panels 14 are packaged within and supported by spaced slotted rails 16 in a manner that allows for secure shipping and curing of masonry panels 14. As depicted, groups of masonry panels 20-23 may be packaged between multiple sets of spaced slotted rails indicated at 26-30. In one embodiment shown, the package 12 is constituted by five sets of slotted rails and four groups of panels. However, it should be understood that package 12 is not limited to this configuration, but can include any number of desired rails and panels. In the example shown, a first group of masonry panels 20 is retained between first and second sets of slotted rails 26 and 27; a second group of masonry panels 21 is retained between second and third sets of slotted rails 27 and 28; a third group of masonry panels 22 is retained between third and fourth sets of slotted rails 28 and 29; and a fourth group of masonry panels 23 is retained between fourth and fifth sets of slotted rails 29 and 30.
Details of masonry panels 14 wilt be discussed in more detail with reference to FIG. 2. At this point, it should be understood that each masonry panel 14 is generally very similar, such that details will only be discussed with reference to masonry panel 14A. Masonry panel 14A includes a main body panel 40 having a front face portion 42 and a back face portion 43. Main body panel 40 includes a slanted or tapered bottom portion 46 and a top portion 47 from which a securing bracket 50 extends. Securing bracket 50 is formed from metal and includes an offset fastener receiving portion 52 adapted to receive fasteners (not shown) in a recessed manner to secure masonry panel 14A to a wall (not shown). First and second manufactured, such as stone or brick, facial portions 56 and 57 extend in respective rows and are attached to front face portion 42 in a vertically spaced and laterally offset or other suitable manner such that a first mortar receiving portion 60 is defined there between. In a manner known in the art, the manufactured facial portions 56 and 57 are made from a colored concrete composition, but may be made from other suitable materials. More specifically, masonry panels 14 are created in a mold (not shown) and partially cured for a suitable period, such as approximately 18-48 hours, before being de-molded. Once de-molded, masonry panels 14 can be packaged in accordance with the method of the present invention, as will be discussed in more detail below.
As best seen in FIG. 1, each slotted rail 16, which can be comprised of wood, plastic or any other suitable material, includes top, bottom and opposing side walls 62-65. Top wall 62 includes a plurality of laterally extending upper slots 66 formed therein. Similarly, bottom wall 63 includes a plurality of laterally spaced lower slots 68 formed therein. Upper slots and lower slots 66 and 68 may have any suitable shape. For example, in the embodiment shown, upper slots 66 comprise rectangular slots and lower slot 68 comprises a rectangular slot having first and second notched portions 70 and 71 at the open end of each slot 68. See FIG. 2. At this point, it should be understood that each slotted rail 16 in rail sets 27-30 are generally the same such that details for each rail need not be separately described. With respect to the bottom slotted rail set 26, this rail set may be formed in the same manner as the other rails sets 27-30 or may include only upper slots 66 formed therein as depicted in FIG. 1. Likewise, it should be understood that the top set of rails 30 of package 12 need not be formed with upper slots 66, as depicted in FIG. 1 and may only include lower slots 68.
Reference will now be made to sets of slotted rails 16A and 16B in FIG. 2 in order to describe a method for packaging masonry panels 14. It should be understood that slotted rails 16A and 16B represent rails from adjacent sets of rails, such as 29 and 30 of FIG. 1. As demonstrated by slotted rail 16A, each upper slot 66′ is adapted to retain a set of back-to-back, paired masonry panels such as 14B and 14C. More specifically, upper slots 66′ are adapted to receive respective bottom portions 46 of masonry panels 14B and 14C, with the angling or tapering of bottom portions 46 aiding in positioning of panels 14B and 14C in upper slots 66′. The depth of each upper slot 66′ is such that a bottom portion 76 of the first facial portion 56 rests upon top wall 62′ of slotted rail 16A when masonry panels 14B and 14C are fully received therein. In other words, as shown in FIG. 2, packaging masonry panels includes the steps of inserting respective bottom portions 46 of a first set of masonry panels 14C into the plurality of upper slots 66′ of the first set of spaced slotted rails 16A such that bottom portions 76 of respective first facial portions 56 abut the top walls 62′ of the slotted rails 16A. In this position, respective securing brackets 50 of masonry panels 14B and 14C are also arranged back-to-back and in contact with one another. In this configuration, offset fastener receiving portions 52 abut and aid in creating an air circulation gap 78 between the respective main body panels 40 of masonry panels 14B, 14C. The remainder of upper slots 66′ in slotted rail 16A may be likewise loaded with masonry panels 14 until each of upper slots 66′ supports two back-to-back masonry panels 14. At this point, it should be noted that the spacing of upper slots 66′ are such that masonry panels 14C and 14D supported by adjacent upper slots 66′ do not touch, and an additional air circulation gap 80 is maintained between manufactured facial portions 56 and 57 of opposing masonry panels 14C and 14D.
Once the desired number of paired masonry panels 14 are loaded into slotted rail 16A, slotted rail 16B is then lowered over respective securing brackets 50 such that the securing brackets 50 of each set of masonry panels, such as 14B, 14C, are received into a respective lower slot 68′ of slotted rail 16B. More specifically, the method of packaging masonry panels further comprises the steps of inserting respective securing brackets 50 of the first set of masonry panels 14B, 14C, into the plurality of lower slots 68′ of a second set of spaced slotted rails (represented by 16B), such that top wall portions (not separately labeled) of respective facial portions 57 abut respective bottom walls 63′ of the second set of spaced slotted rails. As clearly illustrated, lower slots 68′ are multiple times more narrow as compared to upper slots 66′ in order to securely retain masonry panels 14 within slotted rails 16. In use, first and second notched portions 70 and 71 aid in the aligning and loading of masonry panels 14 into slotted rails 16. More specifically, notched portions 70 and 71 provide a wide opening through which securing brackets 50 may be received to help guide securing brackets 50 into lower slots 68′. The process of loading masonry panels 14 between slotted rails 16 is continued until the desired number of levels of masonry panels 14 have been established for package 12. Optionally, one or more braces 84, straps or bands, may be attached to package 12 in order to provide additional stability during transport.
Advantageously, air circulation gaps 78 and 80 between masonry panels 14 provide sufficient circulation such that partially cured masonry panels 14 can be loaded into package 12 of the present invention for additional curing of the panels. Further, the manner in which masonry panels 14 are packaged prevents condensate staining of the manufactured panels 14 as the panels continue to cure. As a result, defective product returns are minimized and customer satisfaction increased. It should also be appreciated that manufacturing and labor costs are reduced by providing a package 12 that also constitutes a shipping container and that allows for further curing of masonry panels 14 without the need for a dryer.
Although described with reference to various embodiments of the invention, it should be readily understood that various changes and/or modifications can be made to the invention without departing from the spirit thereof. For instance, although brick masonry panels are depicted, it should be readily understood that the present system could be utilized in conjunction with other types and styles of manufactured stone products, generally being referred to herein as masonry products or panels, requiring an extended curing period. Further, the number of masonry panels 14 in each group of panels 20-23 is not limited by the example depicted in FIG. 1. In general, the invention is only intended to be limited by the scope of the following claims.
