Description

The patent application claims priority to and herein incorporates by reference Provisional Patent Application No. 61/106,057, entitled “Masonry Structure” and filed on Oct. 16, 2008.

BACKGROUND

1. Field
The present disclosure is related to the field of masonry structures, and more specifically to factory-built masonry structures.
2. Background
Traditional masonry structures such as fireplaces, countertops, brick walls and other hearth products are constructed by a mason and thus can be expensive. Furthermore, they are built on-site and can require significant time to be completed. Because of the above, in recent years, pre-built fireplaces have become popular. Also, factory built fireplaces are an attractive alternative because they can be installed in multi-level buildings.
In designing factory-built fireplace, one goal has been to design fireplaces that resemble traditional masonry built fireplaces. For example, recent designs of factory-built fireplaces have incorporated refractory panels. However, such refractory panels, and other similar designs, have been incapable of achieving the desired masonry look. In an attempt to create a better masonry look, designers have added bricks to the firebox areas of the factory built fireplaces. However, such construction designs have shown to be structurally unstable, often falling and breaking, and thus unable to provide an adequate retention of the bricks. Additionally, in such designs, bricks are usually poorly aligned and do not tend to be capable of providing multiple brick pattern arrangements.

SUMMARY

In one aspect of the disclosure, an apparatus includes a panel, a plurality of fasteners, and a plurality of bricks secured to the panel by the fasteners.
In another aspect of the disclosure, a method of assembling a masonry structure includes arranging a plurality of bricks with a panel, and securing the bricks to the panel with a plurality of fasteners.
In yet another aspect of the disclosure, an apparatus includes a panel, a plurality of bricks, and means for fastening the bricks to the panel.
In a further aspect of the disclosure, a fireplace includes a firebox having a plurality of walls defining an area for a fire, each of the walls having a panel, a plurality of fasteners, and a plurality of bricks secured to the panel by the fasteners.
It is understood that other aspects of the present disclosure will become readily apparent to those skilled in the art from the following detailed description, wherein it is shown and described only exemplary aspects of the disclosure by way of illustration. As will be realized, the disclosure includes other and different aspects and its several details are capable of modification in various other respects, all without departing from the spirit and scope of the present disclosure.

In some instances, well-known structures and components are summarily described and/or shown in block diagram form in order to avoid obscuring the concepts of the present disclosure.
With reference to FIGS. 1A and 1B, masonry fireplace 100 according to an exemplary embodiment is illustrated therein, in this configuration, the panels 40 b, 50 b, and 60 b are factory built, and the whole structure can be assembled on site using the factory built panels. The fireplace 100 generally comprises a firebox 10 having a front end 12 and a rear end 14. The firebox 10 defines a cavity 30 and panels 40 b, 50 b, 60 b are preferably disposed in the cavity 30. In the illustrated embodiment, the fireplace 100 has a chimney outlet 20. However, the fireplace 100 can be vent free, thus not requiring a chimney outlet. The fireplace 100 can be adapted to burn various types of materials. For example, the fireplace 100 can be a wood and/or gas burning fireplace.
FIG. 2 illustrates the fireplace 100 of FIG. 1 with the panels 40 b, 50 b, 60 b removed. The cavity 30 has a frame with a rear area 40 a, side areas 50 a and a base area 60 a. The frame can comprise of at least one rail that defines the periphery of the cavity 30. The frame can optionally comprise a plurality of panels, such as a rear wall 40 a, sidewalls 50 a and a base 60 a. Optionally, the panels 40 b, 50 b, 60 b can comprise the frame areas 40 a, 50 a, 60 a.
The panels 40 b, 50 b, 60 b are preferably removably attached to the rear area 40 a, side areas 50 a, and base area 60 a, respectively. For example, the panels 40 b, 50 b, 60 b can be riveted, bolted, screwed, welded, or connected with other connectors or fasteners to the cavity frame areas 40 a, 50 a, 60 a. In the illustrated embodiment, the panels 40 b, 50 b, 60 b are in the form of masonry panels configured to receive bricks.
The panels 40 b, 50 b, 60 b are preferably made of metal. For example, the panels 40 b, 50 b, 60 b can be made of steel. Optionally, the panels 40 b, 50 b, 60 b can be made of a sheet metal commonly used in the fireplace industry. However, the panels 40 b, 50 b, 60 b can optionally be made of any material providing the necessary structural, thermal, and other characteristics required in fireplace construction.
The panels 40 b, 50 b, 60 b are preferably sized to substantially cover the entire frame areas 40 a, 50 a, 60 a, respectively. Additionally, the panels 40 b, 50 b, 60 b are preferably configured to provide adequate structural support to masonry material disposed thereon. For example, the panels 40 b, 50 b, 60 b can have a thickness capable of providing said structural support.
According to the illustrated embodiment, the panels 40 b, 50 b, 60 b comprise a running bond pattern. However, the panels 40 b, 50 b, 60 b can comprise other patterns, such as a herringbone pattern, as illustrated in FIG. 3.
FIG. 4 illustrates a secure placement of bricks 95 a on a panel 90. The panel 90 provides a means for holding the bricks 92. The panel may be made of metal, similar to the panels 40 b, 50 b, and 60 b described in FIG. 2. The panel 90 comprises a number of holes 91. The bricks 95 a are attached to the panel 92 by rivets 96. At least one rivet 96 gets inserted into each brick 95 a. At least one blind hole 93 in each brick 95 a is aligned with one hole 91 in the panel 90. Through each aligned pair of holes 91 and 93, a rivet 96 is passed to fasten one brick 95 a to the panel 90. The rivets provide means for fastening the bricks to the panel.
FIG. 5 and FIG. 6 show the rivet 96 as inserted into a brick 95 a of the panel 90, through the hole of the brick 93 and the hole of the panel 91. Each rivet 96 has a shaft 97 and a mandrel 98. The rivet 96 has a head 80, and may be made of aluminum. The dimension of the hole of the brick 93, in an area adjacent to the hole of the panel 91, is wider than the dimension of the hole of panel 91. The hole of the panel 91 extends from one side 102 to another side 103. For example, the hole of the brick 93 may be approximately ¼″ wide and the diameter of the hole in the panel may be approximately 3/16″. The diameters of the holes 91 and 93 with respect to one another would have to be selected carefully to assure that adequate support is obtained, especially in view of the size of the rivet 96 and the size of brick 95 a being used The brick 95 a has an upper gap 200 which its diameter extends from one side 104 to another side 105 surrounding the tail 70 of the rivet 96. As shown in FIG. 6, once the top 75 of the mandrel 98, gets fully inserted into the shaft 97, it 98 causes the tail 70 of the rivet 96 to expand. The expanded tail 70 portion of the rivet 96, forms a lock 99 inside each brick 95 a, and thereby further secures the brick 95 a to the panel 90. The brick 95 a is locked into place when the tail 70 expands because it wedges against the side of the hole 93 in the brick 95 a and the tail 70 expands to a diameter larger than the diameter of the hole in the panel 91.
FIG. 7 shows the rear view of the panel 90 of FIG. 4. The panel 90 may be reinforced with a number of stiffeners 85. The stiffeners 85 provide means for stiffening the panel so that the panel can securely and without bending, hold the bricks 95 a attached to it on the other side. An exemplary structure of a stiffener 85 is shown in FIG. 8. The stiffener 85 may be formed as a channel and may be made of metal or another substitute material. The stiffeners 85 runs along the grouting on the opposite side of the bricks.
FIG. 9 illustrates a method of fastening bricks 95 a onto the panel 90 of FIG. 4. The method illustrated in FIG. 11 entails placing a number of bricks 95 a on the panel 90 in the following way. For each brick 95 a, the side with at least one blind hole 93, must face the panel 90. Next the holes of the bricks 93 need to be aligned with the holes of the panel 91. To help the alignment process, a frame 95 may be used. First, the frame 95 is placed on the panel and then the bricks 95 a are placed in each of the holders 95 b of the frame 95. At this point, the holes of the panel 91 are aligned with the holes of the bricks 93, and the rivets 96 are passed through the holes of the panel 91 and then through the holes of the bricks 93. Once the bricks 95 a are fastened, then the frame 95 is removed. Next, the area in between the bricks 86, may be grouted by a grouting material such as cement.
FIG. 10 illustrates one method of cutting of the panel 90 once the bricks 95 a are installed. As shown, a cut is made to form an edge 88 which is at an angle. This is done to fit the cut panel 90 in an area which has an edge with a similar angle. For example, each side of the lower panel 60 b in FIG. 2 is cut at an angle to fit the lower base part 60 a of the fireplace 100. FIG. 11 illustrates another method of cutting the panel 90 with installed bricks 95 a. Here the cut is made along an edge 77 that is tapered. This for placing two panels 90 side to side at an angle with respect to one another. For example, in FIG. 2, the back panel 40 b and one of the side panels 50 b may be cut along an edge 77 to stand next to one another.
In general, some of the configurations described above are for factory-built secured masonry surface coverings, so that they could be installed in a time and cost efficient manner, for various applications. The configurations are specially suited for fireplaces wherein the on-site building of such structures are difficult and/or prohibited by local safety regulations.
