Quoin corner form used in bricklaying

Abstract

A quoin form device and method for constructing a quoin corner and a regular corner on a structure. The quoin form includes a two frames rotatably joined by a central hinge. The frames include parallel proximal and distal members joined by a series of cross-members. Slots are defined between the cross-members to allow egress of mortar during bricklaying. Spacers are attached to the frame, to provide along with the frame, a surface for arranging bricks in a protruding pattern. The frame removably attaches to the structure via a pair of braces and is supported by brackets attached to the bottom of the frame. The regular corner is of a similar configuration but without the spacers so that the brick are flush with an adjoining wall. Furthermore, the method includes use of a twig for quickly running and securing a leveling line to serve as a guide in laying courses of brick.

Description

FIELD OF THE INVENTION

[0002] This invention relates generally to the art of brick laying, more particularly to the art of using a form in brick laying and still more particularly to the art of using a quoin-form in brick laying to create a quoin corner and a regular corner-form for creating a regular corner on a structure.

BACKGROUND OF THE INVENTION

[0003] Brickwork for residential and commercial structures requires great craftsmanship and time on behalf of the bricklayer. Consequently, bricklaying is expensive. Aspects of bricklaying which require particular skill and time include: 1) the formation of regular corners, 2) the construction of quoin corners, and 3) laying level courses of brick during formation of a wall. These constructions are performed by hand, laborious, and particular attention is required to make the corner as close as possible to a true right angle.

[0004] A quoin corner is an inner or outer corner of a structure and has a distinguishing ornamental design formed of stone, brick, other masonry or wood. In recent years, it has become popular to build brick-faced commercial and residential structures having quoin corners constructed of the same brick material as the walls of the structure, but having the quoin corner projected outward from the surface of the structure. For example, the quoin corner is formed by positioning in a pattern some of the bricks flush with the wall while the remaining bricks protrude three-quarters of an inch or an inch from the surfaced of the wall. A common quoin corner pattern is characterized by repeating, from ground to roof, one flush brick then five protruding bricks. Another common quoin corner pattern is repeating two flush brick then five protruding bricks.

[0005] As with the regular corner, quoin corner is laid by hand and must be as close to a true right angle as possible. The protruding-flush arrangement of the bricks makes this particularly difficult. Moreover, the quoin corner must be properly integrated with the walls while having the protruding bricks extend a proper distance from the wall and the flush bricks remain true with the wall. A quoin corner which fails to meet all the requirements is visually unappealing and may be structurally inferior. A prior art method form proper quoin corners include the use of leveling devices coupled with a good eye and craftsmanship learned from years of experience. Consequently, constructing quoin corners is especially troublesome for novice bricklayers and even experienced bricklayers require ample construction time.

[0006] The courses of brick forming the wall between the corners must be level, and also level with the corresponding row of bricks comprising the corners. A current method for maintaining a level wall is to run a string or leveling line between two of the corners. The leveling line is secured at the corners and positioned at a desired height for use a guide for a particular course of brick. To keep the level line from sagging between the corners, a support nail is often pounded into the structure between the corners. This process of running the leveling line positioning a nail to support the leveling line is repeated as the rows of bricks are constructed. Since the leveling line is used as a guide, it is very important that the string is level. However, repeated positioning of a nail to support the leveling line tends to be inaccurate and lends itself to human error.

[0007] Accordingly, what is needed are corner forming devices to respectively aid the bricklayer in the construction of a regular corner and a quoin corner so that the corners can be constructed in a fraction of the time and without requiring exceptional skill. Further needed is a twig device for quickly and accurately positioning a leveling line in the construction of walls.

SUMMARY OF THE INVENTION

[0008] The present invention provides apparatus and methods for brick laying quoin corners, regular corners and maintaining a leveling line. The quoin corner includes two slotted frame members hingedly connected. Horizontal slots within the frame members are evenly spaced and within the members are evenly spaced and run horizontally from the hinged edge of the frame member to the opposing edge of the frame member.

[0009] In use, the frame members are moved about the hinge to form a ninety-degree angle. The form is then spaced away from the corner of a structure and attached to the structure. The form is spaced away from the structure such that a brick may be placed between the wall of the structure and the frame member, with the outside surface of the brick contacting the frame member when said brick protrudes from the main brick surface of the wall by three-quarters of an inch to an inch. The slots within each frame member are proportional in width to the height of the brick being laid within the frame. As each layer of brick and mortar are placed between the structure surface and the frame member, mortar is allowed to escape through the slots in the frame member. Once the quoin corner has been formed and the mortar has had time to partially cure, the invented form can be simply removed from the corner structure. Thus, the invented form allows consistent and efficient brick laying of a brick quoin corner with a consistent amount of protrusion from the main brick surface, and with carefully controlled surface quality and angle measurement.

[0010] In the broadest sense, the present invention includes a first frame member attached to a second frame member. The first and second frame members are substantially rectangular and have planar inner and outer faces. The frame members also include a parallel proximal and distal member and cross members joining the proximal and distal members. The height of each cross member is less than 2½ inches and defines a plurality of parallel slots between the cross members. The slots each have a height greater than ½ inch so to allow mortar to therethrough when in use.

[0011] A object of the present invention is to include a first brace attached to the first frame and a second brace attached to the second frame. The first and second frames are capable of respectively holding the first and second frame members a distance from a structure and capable of adjusting that distance.

[0012] Another object of the present invention is to include a distal bracket removably attachable to the bottom end of the first frame and distal bracket removably attachable to the distal end of the second frame. A removable center bracket is simultaneously attachable to the respective bottom ends of the first and the second frames. The center bracket is capable of holding the first and second frames in a ninety degree relationship.

[0013] A further object of the present invention is to include a central hinge for rotatably joining the first and second frame members.

[0014] A still further object of the present invention is for each slot to have a height in a range of 1 inch to 2 inches. Preferably, the height of each slot is in the range of 1 inch to 1½ inch. More preferably, the height of each slot is in the range of 1½ inches to 2 inches.

[0015] Another object of the present invention is include a first spacer removably attachable to the first frame member and a second spacer to the second frame member. The spacer has a proximal end, a distal end, and a first member joining said proximal end to said distal end.

[0016] Still another object of the present invention is to provide a first member having a height less than 2¼ inches and cross members each having a height less than 2¼ inches.

DETAILED DESCRIPTION

[0023] FIG. 1 illustrates a quoin form 10 for making a quoin corner on a structure such as a residential or commercial building. The quoin form 10 includes two frames 12 rotatably joined by a central hinge 14. The frames 12, and components attached to the frames 12, are mirror images of each other. Consequently, the disclosure typically will be directed towards one frame 12, but applies equally to both frames 12.

[0024] The frame 12 preferably is unitary, substantially rectangular in shape, and formed of a sufficiently rigid, durable material such as metal or sturdy polymer material. The frame 12 includes parallel, proximal and distal, height-wise members 16, 18. The proximal member 16 is secured to the central hinge 14 and the distal member 18 forms an outer end of the frame 12. A series of parallel, horizontal cross-members 20 join the proximal and distal members 16, 18. The cross-members 20 typically are the same size, elongate and extend, as measured from the central hinge 14, a distance greater than the horizontal width of the desired quoin corner. Typically, this distance is sufficient to accommodate the length of 2 or 2½ standard bricks. Furthermore, the cross-members 20 have a height less than a standard brick; 2¼ inches. (A standard brick is 8 to 8¼ inches wide, 2¼ to 2½ inches high, and 3¾ to 3⅞ inches deep). Preferably the height of the cross-members 20 is in the range of ½ inch to 2 inches, and more preferably within the range of ½ inch and 1 inch.

[0025] An adjustable brace 22 is attached to the upper end of the distal member 18 for attaching the quoin form 10 to a structure. The brace 22 includes a bolt 24 attached to, and extending upward from, the distal member 18; an elongate bracket 26 movable on the bolt 24; a spacer 28 and a washer 30 positioned on the bolt 24 to elevate the bracket 26 above the distal member 18; and a wingnut 32 attached to the terminal end of the bolt 24 to removably secure the bracket 26 in a position.

[0026] The elongate bracket 22 includes a main body 34 and an end portion 36 bent ninety degrees from the main body 34 to conform to a surface of a structure. The main body 34 has an elongate slot 38 which receives the bolt 24 and allows the quoin form 10 to be positioned closer to, or further from, the structure. The end portion 36 is provided with a hole 40 for receiving a nail which secures the quoin form 10 to the structure.

[0027] A level 42 is positioned at the top edge of the uppermost cross-member 44 to provide a means for ensuring the quoin form 10 is level.

[0028] The cross-members 20 define a series of parallel horizontal slots 46 therebetween which terminate at the proximal and distal members 16, 18. The slots 46 are elongate and extend horizontally substantially the same distance as the cross-members 20. The height of each slot 46 is at least ½ inch preferably between 1 and 2 inches, more preferably between 1 and 1½ inches, and more preferably still between 1½ and 1¾ inches. The combined height of the cross-members and the slots 46 are configured so that when in use each slot 46 corresponds to a mortar interface between courses of brick to allow egress of excess mortar from between the bricks. The cross-members 20 are positioned adjacent the brick courses and form a planar inward facing surface against which the bricks are aligned.

[0029] A notch 48 is cut into the distal member at the outer terminal end of the slot. The notch 48 is sized and positioned to hold a leveling line at a height suitable to serve as a guide.

[0030] To create a pattern of flush and protruding bricks, a widthwise spacer is removably attached to the frame 12, such as the single-brick widthwise spacer 50 shown in FIG. 1. The single-brick widthwise spacer 50 includes proximal and distal downward extending leg sections 54, 56 which and a member 57 joining the legs sections 54, 56. The member 57 has the same height as the cross-members 20, that is, less than the height of a brick, and is used to position the flush course of bricks. Additionally, the widthwise spacer 50 extends the width of the frame 12 with the proximal edge terminating in a 45 degree chamfer 52 such that when the chamfers 52 abut one another the quoin form 10 is positioned at a 90 degree angle.

[0031] The widthwise spacer 50 is removably attached to the bottommost cross-member 58 of the frame 12 by any suitable manner such as the shown bolts 60 and wing-nuts 62. The widthwise spacer 50 has holes 64 which align with holes 66 in the bottommost cross-member 58 to receive the bolts 68.

[0032] The bricks forming the first course are placed abutting the widthwise spacer 50. Succeeding courses of brick are placed abutting the cross members 20 and, consequently, protrude beyond the flush bricks a distance approximately equal to the depth of the widthwise spacer 50. Typically, the thickness of the spacer 50 is ¾ inch or one inch, however, widthwise spacers of different depths can be interchangeably used to select the amount of protrusion.

[0033] A vertically oriented heightwise spacer 70 can also be removably attached to the frame 12 for use in conjunction with the widthwise spacer 50. The heightwise spacer 70 forms an outer boundary to assist in the proper positioning of the protruding bricks. The heightwise spacer 70 is attached to the frame 12 by any suitable manner, such as the shown bolts 72 and wing-nuts 74. Holes 76 are provided in the heightwise spacer 70 which align with holes 78 in the frame 12 to receive the bolts 72. Additionally, a plurality of holes (not shown) can be provided in the cross-members 20 to allow adjustment of the heightwise spacer 70 to accommodate more or less bricks. Typically, the heightwise spacer 70 is positioned to accommodate 2 to 2½ standard bricks.

[0034] Two sets of brackets, starter brackets and continuation brackets, are removably attachable between the spacer leg sections 54, 56 and the proximal and distal members 16, 18. The starter brackets are used when constructing the first segment of the quoin corner, that is, one complete pattern of bricks. The starter brackets include a distal starter bracket 84 and a center starter bracket 86. The distal starter bracket 84 has a main body 88, an insertion portion 90 directed ninety degrees upwards from the main body 88 and an outer lip 92 directed ninety degrees downwards from the main body 88. The outer lip 92 is outwardly spaced about ½ inch to 1½ inches from the insertion portion 90 along the main body 88. Preferably, the outer lip 92 is spaced about ¾ inch from the insertion portion 90. A offset between the outer lip 92 and the insertion portion 90 is sized to accommodate the depth of the widthwise spacer 50 so that the bricks placed against the widthwise spacer 50 are flush in relation to the adjacent wall.

[0035] When in use, the insertion portion 90 is secured between the distal member 18 and the widthwise spacer 50. The leading edge of the main body 88 is placed atop the foundation to keep the quoin form 10 from moving. The outer lip 92 abuts the corner of the foundation upon which the quoin form 10 is to be built and to hold the quoin form 10 in place.

[0036] The center starter bracket 86 is similar to the distal starter bracket 84 and includes a main body 98, an insertion portion 100, and an offset outer lip 102. The offset is the same amount as for the distal starter brackets 84. However, the center starter bracket 86 is configured to be operational along a ninety degree angle. Accordingly, the outer lip 102 holds the quoin form 10 about a corner of the foundation and the insertion portion 100 is inserted between the proximal members 16 and the widthwise spacers 50 to hold the quoin form 10 at a right angle.

[0037] After the first segment is laid, the distal and center continuation brackets 103, 104 as illustrated in FIG. 2, replace the starter brackets to position and hold the quoin form 10 in place for construction of subsequent segments on top the first segment. The distal continuation bracket 103 includes a main body 105, an upward extending insertion portion 106 and a downward extending lip 107.

[0038] The center continuation bracket 104 is similar to the distal continuation bracket 103 and includes a main body 108, an insertion portion 109, and a lip 110. However, the center continuation bracket 104 is configured to be operational along a ninety degree angle.

[0039] The continuation brackets 103, 104 are generally similar in configuration and operation as the starter brackets 84, 86, except that the insertion portion 106, 109 and the lip 107, 108 are generally aligned in a common plane. Consequently, when in use, the lip 107, 108 is properly positioned adjacent to the outer surface of the preceding course of brick so to maintain the quoin form 10 in proper position.

[0040] Alternative heightwise spacers can also be used to dictate any desired number of courses of brick. For example, FIG. 3 shows a quoin form 10A configured the same as illustrated in FIG. 1, but having a double-brick widthwise spacer 114. The double-brick widthwise spacer 114 is similar to the single-brick widthwise spacer 50, but sized to flushly position two courses of brick.

[0041] The double-brick spacer 114 has a proximal member 116, a distal member 118, and two parallel cross-members 120 joining the proximal and distal members 116, 118. The proximal end of the double-brick spacer 114 terminates in a 45 degree chamfer 122 so that when the chamfers 122 abut one another the quoin form 10 is positioned at ninety degrees. The cross-members 120 define a slot 124 therebetween. The cross-members 120 and the slot are configured in the same relationship as the cross-members 20 and slots 46 previously described in regards to FIG. 1. Accordingly, when in use, the cross-members 120 align adjacent to the front surface of the brick courses and the slot 124 aligns with the mortar between the courses.

[0042] The double-brick spacer 114 is removably attached to the bottommost cross-member 126 of the frame 12 by any suitable manner such as the shown bolts 128 and wing-nuts 130. The double-brick spacer 114 has holes 132 which align with holes 134 in the bottommost cross-member 126 to receive the bolts 128. The double-brick spacer 114 is also provided with downward extending proximal and distal legs 136, 138 to which holding plates 140 are removably attached. The legs 136, 138 and holding plates 140 are provided with holes 141, 142, 143 through which wing-nuts 144, 145 and bolts 146, 147 secure the plates 140 to the legs 136, 138. The plates 140 and the legs 136, 138 function to removably secure brackets therebetween. The same starter brackets 84 and continuation brackets 103, 104 described above and illustrated in FIGS. 1 and 2 are used with the double spacer quoin form 10A.

[0043] Both of the previously described quoin forms 10, 10A can be used to form a quoin corner of an inner corner of a structure, in addition to the previously discussed outer corner. To do so, the frames 12 are rotated to form a 270 degree angle with the widthwise spacers attached to the obtuse side. The chamfers of the widthwise spacers 50 can engage by properly positioning a set of opening in the frame 12 for securing the widthwise spacer. Additionally, the distal brackets 84. 103 are each inserted to face the inner corner. An inside center quoin bracket, having a main body, an insertion portion directed ninety degrees upwards from the main body, and an outer lip directed ninety degrees downwards from the main body, is configured to be operational along the 270 degree angle formed by frames. (This embodiment is not shown).

[0044] Another alternative is to provide the quoin form 10, 10A with spacers and center brackets for the construction of both inner and outer corners. In this alternative, the level device and the attachment means are positioned on the top edge of the frame 12 so to not interfere with bricklaying. In a further alternative, the two frames 12 are fixedly secured togther at ninety degrees.

[0045] FIG. 4 illustrates a regular corner form 150 for making a both outer and inner regular corners on a structure. The illustrated regular corner form 150, shown in position to make an outer corner, includes two frames 152 rotatably joined by a central hinge 154. Alternatively, the frames 152 can be fixedly secured together at ninety degrees without a central hinge. The frames 152, and components attached to the frames 152, are mirror images of each other. Consequently, the disclosure typically will be directed towards one frame 152, but applies equally to both frames 152.

[0046] The regular corner form 150 is configured similar to the quoin form 10 but without the spacers 50, 70. That is, the regular corner form 150 includes proximal and distal height-wise members 156, 158 wherein the distal members 158 are provided with a notch 160 for attaching a leveling line; a series of parallel, horizontal cross-members 162 join the proximal and distal members 156, 158; slots 164 are defined between the cross-members 162; a leveling device 166 is provided; and a brace 168 is provided for attaching the frame 12 to a structure.

[0047] The regular corner form 150 uses different distal and center brackets 170, 172 than the quoin form 10. The distal and center brackets 170, 172 are removably attachable to the lower end of the frame 152 for holding the frame 152 in position. The distal bracket 170 includes horizontally extending plate 174 for insertion into the mortar between courses of brick and thereby supporting the regular form 150; a pair of plates 176 extending ninety degrees upward from the horizontal plates 174 and defining a channel 178 therebetween for receiving the lower end of the frame 152; and a plate 180 extending ninety degrees downward from the horizontal plates 174 to align the regular form 150 flushly with the external surface of the corner.

[0048] The center bracket 172 includes a horizontal plates 184, a pair of upward extending plates 186, 187 defining a channel 188 therebetween, and downward extending plates 190 similar to the distal bracket 170, but configured to be operational along a ninety degree angle. Accordingly, lower edges of the frames 152 are held within the channels 188 at a right angle and the downward extending plates 190 hold the regular form 150 about a corner of the structure. The brackets 170, 182 are used as both starter and continuation brackets.

[0049] To construct an inner corner, the distal bracket 170 and the brace 168 are faced in the opposite direction to that shown in FIG. 4. Although the same center bracket 172 can be used, an inner corner center bracket, or a modified center bracket is preferred (not shown). For example, an inner corner center bracket can be configured similar to the center bracket 182, but with the horizontal plate extending in the opposite direction and the downward extending plates positioned to be flush against the wall when in use.

[0050] FIG. 5 shows a twig 200 for quickly and accurately keeping a level line from sagging and thereby serving as a guide for laying level courses of brick. The twig 200 is essentially configured as one frame 152 of the regular corner form 150 by comprising parallel proximal and distal side members 202, 204; a series of parallel, horizontal cross-members 206 joining the proximal and distal members 202, 204 and defining slots 213 therebetween; a leveling device 208; braces 210; and distal brackets 212. The cross-members 206 and the slots 213 are configured as previously described in relation to FIG. 1, but preferably having a shorter width.

[0051] The differences include that the twig 200 utilizes a second removably attachable distal bracket 212 instead a center bracket, and has two adjustment braces 210. Additionally, each cross-member 206 is provided with a means for attaching the level line by any suitable attachment device such as, for example, a hook, bob or boss. The level line attachment means 214 is preferably attached to the upper edge, at the midpoint, of the cross-members 206 and extends slightly into the slot 213.

[0052] In constructing a quoin corner, the desired widthwise spacer is selected depending on the pattern of protruding and flush bricks desired and the amount of protrusion. The quoin form 10 is rotated until the beveled 45 degree chamfers 52 of the widthwise spacers 50 engage. The insertion portion 90 of the brackets 84, 86 are inserted and tighten between the widthwise spacer 50 and the frame 12. The central bracket 86 and the chamfers 52 maintain the quoin corner form at 90 degrees. Proper distance between the structure and the invented form is determined and the quoin form 10 is securely positioned accordingly by use of the brackets 84, 86 and the adjustment brace 22.

[0053] Mortar and brick are then laid between the frame wall and the quoin form 10 with the initial layer of brick resting on the main body starter brackets 84, 86. The slots 46 in the frame 12 align with succeeding mortar joints from the foundation up. Succeeding courses of brick are placed abutting the widthwise spacer 50 and the cross-members 20 to form a consistent quoin corner. Since the cross-members 20 are spaced farther from the structure than the widthwise spacer 50, the bricks abutting the cross-members 20 will protrude from the corner. As the brick and mortar are laid within the quoin form 10, excess mortar escapes through the slots 46.

[0054] To construct a second segment of the brick pattern, the quoin form 10 is easily removed by unattaching the brace from the structure and removing the starter brackets 84, 86 from the semi-hardened mortar. Thereafter, continuation brackets 94, 96 are attached and used to position the quoin form 10 atop the newly constructed first segment of the quoin corner. The adjustable brace 22 is then attached to the structure to secure the quoin form 10. Brick and mortar are laid, in the same manner as the initial process, on top the first quoin corner segment. This process is repeated until a desired height is reached.

[0055] The regular corner form 150 is used to construct a standard brick corner. That is, a corner in which all of the bricks are flush with a respective wall. The regular corner form 150 is used essentially the same as the quoin corner form 10 except the regular form 150 uses the same brackets 170, 172 for both starter and continuation brackets, and there are no spacers.

[0056] The twig 200 is used in conjunction with either the quoin or regular corner forms 10, 150. The twig 200 is position between the corner forms 10, 150; spaced a distance from the structure wall so that brick can be laid between the twig 200 and the structure wall; and attached to the structure wall by use of the adjustable braces 210. A leveling line is ran between the corner forms 10, 150 and the twig 200 to serve as a guide for laying a level course of brick. The leveling line is releasable positioned in the notches 48, 160 of the corner forms 10, 150 and in the line attachment means 214 of the twig 200. Since the notches 48, 160 of the corner forms 10, 150 and the line attachment means 214 are equivalently spaced, the level line can quickly be removed from a row and accurately positioned on a subsequent row.

[0057] The preferred height of the quoin corner form 10 is oriented to one course of flush bricks followed by five courses of protruding bricks. Another preferred arrangement calls for a quoin form 10A capable of retaining two courses of flush bricks followed by five courses of protruding bricks. However, the present invention is not restricted by these preferred arrangements and other configurations are also acceptable. For example, the height of the quoin form can be adjusted to accommodate more or less protruding or flush bricks. As another example, multiple widthwise spacers can be used to vary to pattern of bricks. As a further example, although preferred that the quoin and regular corner form be separate devices, the quoin form can be used to make regular corner by removing the spacers.
