The splice plates are attached together end to end such that a longitudinal end of each splice plate is attached to a longitudinal end of at least one other splice plate.
Description
FIELD OF THE INVENTION

The present invention generally relates to a lintel for use in building construction, and more specifically, to a masonry lintel useful to span wide openings.


BACKGROUND

Relatively large openings such as walkways and archways provide an aesthetically pleasing feature of construction in buildings and other structures. Moreover such architectural features permit passage of large objects through a structure. Generally, lintels span the distance between two spaced supports. It can be challenging to construct a lintel over an opening when the construction is masonry. It is necessary to support the masonry as it is being built over the opening. This can be done by providing support underneath, but this does not provide a clean look in the finished structure because they are exposed. Concealed lintel support systems are known for use in constructing masonry lintels, but have limitations as the span of the opening in the structure increases.


SUMMARY

In one aspect, a lintel system for supporting masonry blocks above an opening in a structure generally comprises a lintel having a length configured to span a width of the opening. Support plates each have an opening within a perimeter of the support plate and a slot therein for receiving the lintel therein for mounting the support plate on the lintel. A support rod is receivable through the opening in the support plate and configured to be received through the masonry blocks for connecting the masonry blocks to the lintel. The lintel comprises a plurality of separately formed, elongate plate members each having opposite longitudinal ends. The plate members are attached together end to end along the length of the lintel such that a longitudinal end of each plate member is attached to a longitudinal end of at least one other plate member.


In another aspect, a lintel system for supporting masonry blocks above an opening in a structure generally comprises a lintel configured to span a width of the opening. Support plates each have an opening within a perimeter of the support plate and a slot therein for receiving the lintel therein for mounting the support plate on the lintel. A support rod is receivable through the opening in the support plate and configured to be received through the masonry blocks for connecting the masonry blocks to the lintel. The lintel comprises a plurality of plate members attached to each other. Each plate member includes one of a projection and a recess. A projection on a first plate member is configured to be received in a recess of a second plate member adjacent the first plate member for interlocking the first and second plate members together.


Other objects and features will be in part apparent and in part pointed out hereinafter.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1-2, a masonry lintel system indicated generally at 10 includes support plates 11 mounted between a pair of lintels 12. Masonry support rods 13 extend through openings in the support plates 11 and between adjacent ones of the support plates. The support plates 11 have slots that receive portions of the lintels 12 for mounting the support plates on the lintels. As described more fully hereinafter, the lintel 12 is formed from a plurality of splice plates 14 (broadly, “plate members”). The lintel 12 spans the width of an archway opening 16 formed by masonry blocks in the form of bricks 18. The bricks have holes in them that receive the support rods 13. The support rods transfer the weight of the bricks to the support plates 11, which in turn transfer the weight to the lintels 12. In this way, the lintel system 10 supports the weight of the bricks 18 above the archway opening 16. The lintel system 10 is configured such that it is concealed within the bricks 18 when the archway is complete. Although the lintel system 10 includes two lintels 12 of the same construction in FIG. 1, a lintel system may include fewer or additional lintels. The splice plates 14 lintels 12 to be manufactured more efficiently while configuring the lintels to have adequate strength so that the lintel system 10 is capable of supporting the weight of the bricks 18 in an archway having a relatively long span.


The lintel 12 comprises arcuate splice plates 14A, 14B, 14C, 14D joined together to define an arch shaped spanning member 20 and base members 22 disposed at longitudinal ends of the lintel. The base members 22 extend laterally from splice plates 14A and 14D. As shown in FIG. 1, in use, the base members 22 are configured to rest on horizontal surfaces of the bricks 18 to position the lintel 12 above side walls of the archway opening 16. In one embodiment, the lintel 12, including the splice plates 14, is formed from steel and has a length L of about 12 feet (4 meters) and a thickness T of about 0.38 inches (0.97 cm). Other dimensions for the lintel are envisioned without departing from the scope of the disclosure. Broadly, the lintel 12 is a “plate type” lintel. The lintel could have over configurations such “box type” without departing from the scope of the disclosure.


Referring to FIGS. 1A-2A, the splice plates 14 interlock with each other and are welded together to form the lintel 12. A first splice plate 14A defines a leftmost portion of the lintel 12, as viewed from the vantage of FIG. 1A, and includes a base member 22 at one end and an interlocking formation 24A (FIG. 2) at an opposite end. The interlocking formation 24A comprises a center enlarged head projection 26 and a pair of side projections 28 on either side of the center projection. The center enlarged head projection 26 comprises a narrowed connecting neck 30 and a rectangular shaped enlarged head 32 having rounded corners. The side projections 28 each comprise a narrowed connecting neck 34 and an enlarged head 36. The projections 26, 28 define enlarged end recesses 38 each including a narrow first portion and an enlarged second portion. A fourth splice plate 14D defines a rightmost portion of the lintel 12, as viewed from the vantage of FIG. 1A, and includes a base member 22 at one end and an interlocking formation 24F at an opposite end. The fourth splice plate 14D is identical to the first splice plate 14A and thus the interlocking formation 24F is identical to the interlocking formation 24A on the first splice plate. It will be understood that the splice plates at the ends of a lintel need not be identical within the scope of the present invention.


Referring to FIG. 2B, a second splice plate 14B defines a left center portion of the lintel 12, as viewed from the vantage of FIG. 1A, and includes a first interlocking formation 24B at one end and a second interlocking formation 24C at an opposite end. The second interlocking formation 24C is identical to the interlocking formation 24A on the first splice plate 14A. The first interlocking formation 24B comprises a pair of enlarged head projections 44 each comprising a narrowed connecting neck 46 and a round enlarged head 48. The projections 44 define a center enlarged end recess 50 and a pair of side recesses 52. The center enlarged end recess 50 comprises a narrow first portion and an enlarged second portion. The enlarged head projections 44 are configured to mate with the enlarged end recess 38 in the first splice plate 14A, the center enlarged head projection 26 on the first splice plate is configured to mate with the center enlarged end recess 50 on the second splice plate, and the side projections 28 on the first splice plate 14A are configured to mate with the side recesses 52 in the second splice plate 14B. Thus, the splice plates 14A, 14B are configured to fit together like puzzle pieces.


A third splice plate 14C defines a right center portion of the lintel 12, as viewed from the vantage of FIG. 1A, and includes a first interlocking formation 24D at one end and a second interlocking formation 24E at an opposite end. The first and second interlocking formations 24D, 24E are identical to the first interlocking formation 24B on the second splice plate 14B. Thus, the first interlocking formation 24D is configured to mate with the second interlocking formation 24C on the second splice plate 14B, and the second interlocking formation 24E is configured to mate with the interlocking formation 24F on the fourth splice plate 14D. In this embodiment, the interlocking formations 24A-24F and the welds connecting the splice plates 14A-14D comprise attachment mechanisms. After the splice plates 14A-14D are connected together, they can be permanently joined as by welding along the interface of adjoining splice plates. Therefore, each of the splice plates 14A, 14B, 14C, 14D is configured to fit together with at least one other splice plate like puzzle pieces. The configuration of the connection is such that even prior to welding, the splice plates 14A-14D cannot be disconnecting by pulling apart within the plane of the first and second splice plates.


In the illustrated embodiment, the lintel 12 is arch shaped. However other configurations of the lintel are envisioned. For example, as shown in FIG. 3, a lintel 112, similar to lintel 12, has a straight, flat, rectangular shape. Lintels of the type described herein may be used in lintel systems having only a single lintel, in pairs as shown in FIG. 1 or in any suitable combination for a particular job.


Referring to FIGS. 4-5C, a lintel 212 comprises a plurality of arcuate splice plates 214A, 214B, 214C, 214D defining an arch shaped plate member 220 and base members 222 disposed at longitudinal ends of the lintel. The base members 222 extend laterally from splice plates 214A and 214D.


Referring to FIGS. 4 and 5A, the splice plates 214 interlock with each other and are welded together to form the lintel 212. A first splice plate 214A defines a leftmost portion of the lintel 212, as viewed from the vantage of FIG. 4, and includes a base member 222 at one end and an interlocking formation 224A at an opposite end. The interlocking formation 224A comprises a pair of side projections 228 each comprising a narrowed connecting neck 234 and an enlarged head 236. The projections 228 define a central recess 238 including a narrow first portion and an enlarged second portion. A fourth splice plate 214D defines a rightmost portion of the lintel 212, as viewed from the vantage of FIG. 4, and includes a base member 222 at one end and an interlocking formation 224F at an opposite end. The fourth splice plate 214D is identical to the first splice plate 214A and thus the interlocking formation 224F is identical to the interlocking formation 224A on the first splice plate.


Referring to FIG. 5B, a second splice plate 214B defines a left center portion of the lintel 212, as viewed from the vantage of FIG. 4, and includes a first interlocking formation 224B at one end and a second interlocking formation 224C at an opposite end. The second interlocking formation 224C is identical to the interlocking formation 224A on the first splice plate 214A. The first interlocking formation 224B comprises a single, central projection 244 comprising a narrowed connecting neck 246 and a round enlarged head 248. The projection 244 defines a pair of side recesses 252. The enlarged head projection 244 is configured to mate with the enlarged end recess 238 in the first splice plate 214A, and the side projections 228 on the first splice plate 214A are configured to mate with the side recesses 252 in the second splice plate 214B. Thus, the splice plates 214A, 214B are configured to fit together like puzzle pieces.


Referring to FIG. 5C, a third splice plate 214C defines a right center portion of the lintel 212, as viewed from the vantage of FIG. 4, and includes a first interlocking formation 224D at one end and a second interlocking formation 224E at an opposite end. The first and second interlocking formations 224D, 224E are identical to the first interlocking formation 224B on the second splice plate 214B. Thus, the first interlocking formation 224D is configured to mate with the second interlocking formation 224C on the second splice plate 214B, and the second interlocking formation 224E is configured to mate with the interlocking formation 224F on the fourth splice plate 214D. In this embodiment, the interlocking formations 224A-224F and the welds connecting the splice plates 214A-214D comprise attachment mechanisms. Therefore, each of the splice plates 214A, 214B, 214C, 214D is configured to fit together with at least one other splice plate like puzzle pieces. Thus, even prior to welding the splice plates 214A-214D cannot be separated from each other by pulling in the plane of the splice plates.


In the illustrated embodiment, the lintel 212 is arch shaped. However other configurations of the lintel are envisioned. For example, as shown in FIG. 6, a lintel 312, similar to lintel 212, but has a straight, flat rectangular shape.


Referring to FIGS. 7-8C, a lintel 412 comprises a plurality of arcuate splice plates 414A, 414B, 414C, 414D defining an arch shaped plate member 420 and base members 422 disposed at longitudinal ends of the lintel. The base members 422 extend laterally from splice plates 414A and 414D.


Referring to FIGS. 7-8A, the splice plates 414 interlock with each other and are welded together to form the lintel 412. The lintel includes a spanning member 420 and a base member 422. A first splice plate 414A defines a leftmost portion of the lintel 412, as viewed from the vantage of FIG. 7, and includes one of the base members 422 at one end and an interlocking formation 424A at an opposite end. The interlocking formation 424A comprises an angled projection 426 at a bottom of the formation and a recess 438 at a top of the formation. The angled projection 426 includes an angled transition surface 431. In the illustrated embodiment, the angled transition surface 431 extends from a floor of the recess 438 at an angle of about 45 degrees. The angled transition surface 431 could extend at other angles without departing from the scope of the disclosure. A fourth splice plate 414D defines a rightmost portion of the lintel 412, as viewed from the vantage of FIG. 7, and includes the other of the base members 422 at one end and an interlocking formation 424F at an opposite end. The fourth splice plate 414D is identical to the first splice plate 414A and thus the interlocking formation 424F is identical to the interlocking formation 424A on the first splice plate.


Referring to FIG. 8B, a second splice plate 414B defines a left center portion of the lintel 412, as viewed from the vantage of FIG. 7, and includes a first interlocking formation 424B at one end and a second interlocking formation 424C at an opposite end. The second interlocking formation 424C is identical to the interlocking formation 424A on the first splice plate 414A. The first interlocking formation 424B comprises an angled projection 444 at a top of the formation and a recess 452 at a bottom of the recess. The angled projection 444 includes an angled transition surface 447. In the illustrated embodiment, the angled transition surface 447 extends from a floor of the recess 452 at an angle of about 45 degrees. The angled transition surface 447 could extend at other angles without departing from the scope of the disclosure. The angled projection 444 is configured to mate with the recess 438 in the first splice plate 414A, and the angled projection 426 on the first splice plate 414A is configured to mate with the recess 452 in the second splice plate 414B such that the angled transition surfaces 431, 447 engage engaged each other. Thus, the splice plates 414A, 414B are configured to fit together like puzzle pieces.


Referring to FIG. 8C, a third splice plate 414C defines a right center portion of the lintel 412, as viewed from the vantage of FIG. 7, and includes a first interlocking formation 424D at one end and a second interlocking formation 424E at an opposite end. The first and second interlocking formations 424D, 424E are identical to the first interlocking formation 424B on the second splice plate 414B. Thus, the first interlocking formation 424D is configured to mate with the second interlocking formation 424C on the second splice plate 414B, and the second interlocking formation 424E is configured to mate with the interlocking formation 424F on the fourth splice plate 414D. In this embodiment, the interlocking formations 424A-424F and the welds connecting the splice plates 414A-414D comprise attachment mechanisms. Therefore, each of the splice plates 414A, 414B, 414C, 414D is configured to fit together with at least one other splice plate like puzzle pieces. It will be appreciated that in this embodiment, the splice plates 414 are not mechanically interlocked prior to being joined by welding or in another suitable manner.

In the illustrated embodiment, lintel 2212 is arch shaped. However other configurations of the lintel are envisioned. For example, as shown in FIGS. 41 and 42, a lintel 2312, similar to lintel 2212, has a straight, flat, rectangular shape. In this embodiment, the attachment plates 2325A, 2325B (broadly, “attachment mechanisms”) have a straight, rectangular shape.


In the illustrated embodiment, the attachment plates 2225A, 2225B are welded to the lintel 2212. However other ways of attaching the attachment plates to the lintel are envisioned. For example, as shown in FIGS. 43-45, a lintel 2412, substantially identical to lintel 2012, comprises attachment plates 2425A, 2425B (broadly, “attachment mechanisms”) bolted to lintel 2412.


In the illustrated embodiment, lintel 2412 is arch shaped. However other configurations of the lintel are envisioned. For example, as shown in FIGS. 46 and 47, a lintel 2512, similar to lintel 2412, has a flat rectangular shape.
