Brace system for vertical beams
The present invention provides an apparatus and method to selectively adjust and temporarily retain a vertical beam in a desired position quickly and with a high accuracy, while not damaging an outer surface of the beam.
1. Field of the Invention
The present invention relates to bracing of vertical beams in the construction industry.
2. Description of the Related Art
In the construction industry, vertical beams are used to support structural elements of a building such as walls, floors and trusses. Prior to permanently connecting the surrounding structural elements that a vertical beam is intended to support, it must be plumbed. Obtaining a true vertical orientation is important to the structural integrity of the overall final building or structure.
The brace 10 is fastened using any acceptable technique to the worker that is compatible with the beam 12 and the floor 18. For example, if the beam 12 is made of wood, the plate 14 is usually nailed or set with screws into the beam 12. If the beam is made of metal, the plate 14 is welded to the beam 12. If it is made of other materials, then other techniques are used, under the selection of the worker who has the task of plumbing the beams 12.
Once the brace 10 is affixed to the beam 12 and to the floor 18 as described above, and the length of the brace 10 can be adjusted, via the turnbuckles 20, to position the beam 12 in a desired vertical position. The brace 10 remains in place to retain the beam 12 until construction workers have had an opportunity to permanently connect the structural elements supported by the vertical beam 12. Often times, however, due to weather or construction project scheduling needs, it may be a number of days or even weeks after the brace 10 has been installed before workers permanently attach the remaining structural elements supported by the beam 12 to hold it fixed in the correct position so that the temporary braces may be removed. During this time, other work taking place near the construction site may disturb the vertical orientation of the beam 12. Thus, it may be necessary to further adjust the vertical orientation of the beam 12 by turning the turnbuckles 20 and/or by changing the location at which the bottom portion 13 of the brace 10 is adhered to the floor 18. After the structural elements attaching to the beam are securely fastened, the brace 10 used to plumb the beam 12 is removed.
The prior art brace 10 has several disadvantages. First, it is time consuming and costly to install. For example, when the beam 12 is made of steel, welders are often subcontracted and summoned to the construction site to weld or bond the plate 14 to the top portion of the beam 12. Hiring additional skilled laborers costs money, takes time to schedule and perform the work, and often causes project timeline delays.
Second, welding, nailing, or otherwise fastening the brace 10 to the top portion of the beam 12 leaves holes and weld marks in the outer surface of the beam 12. Often times, very expensive and aesthetically beautiful pieces of wood or steel columns are used in construction projects, and the architectural design of the overall project is such that the top portion of the beam 12 is intended to remain visually exposed throughout the life of the finished project. Thus, holes and weld marks on the outer surface of the beam 12 are undesirable as they detract from the overall beauty of the beam.
Third, due to the rigid top and bottom portions 11, 13 of the brace 10, a miscalculation during a first installation attempt can result in a situation where the top portion 11 of the brace is welded or nailed too high on the beam 12 such that the bottom portion 13 of the brace 10 cannot be securely fastened to floor 18 without the use of a shim, or without requiring that the top portion 11 of the brace be repositioned.
Yet another shortcoming is that the brace 10 is fastened according to the skill and care of the individual worker assigned to the task. Some workers may not take proper care in the task or may mar a high quality beam. Other workers must then repair the beam or replumb the beam because the first worker did not have sufficient skill or training for the task, or did not take sufficient care.
BRIEF SUMMARY OF THE INVENTIONThe present invention provides an apparatus and method to selectively adjust and temporarily retain a vertical beam in a desired position quickly and with a high accuracy, while not damaging an outer surface of the beam.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
The brace assembly 54 includes a bracing rod 58 and a clamp assembly 65. The clamp assembly 65 includes head brackets 66, 68 and fastening rods 70, 72.
The brace assembly 54 also includes a floor plate 16 coupled to the bracing rod for connecting the bracing rod to the floor 59.
In operation, the beam 52 can be plumbed in the “x” direction by making adjustments to the bracing rod 58 of the first brace assembly 54, and plumbed in the “z” direction by making adjustments to the bracing rod 60 of the second brace assembly 56. Adjustments can be made to the respective bracing rod 58, 60 of each of the first and the second brace assembly 54, 56 by (1) changing the length of the bracing rod 58, 60 (2) pivoting a bottom portion 58a, 60a of the bracing rod to change the angle α between the each bracing rod 58, 60 and a floor 59, or (3) by changing both the length of the bracing rod 58, 60 and pivoting the bracing rod 58, 60.
Turnbuckles allow a user to increase the length of a rod by turning the turnbuckle 62 in a first direction, and to shorten the length of a rod by turning the turnbuckle 62 in a second direction. In the present invention, turnbuckles 62 can be used to selectively increase the length of the bracing rod 58, 60 and thereby push the top of the beam 52 further away from the point where each bracing rod 58, 60 is anchored to the floor 59, and to selectively decrease the length of the bracing rod 58, 60 and thereby pull the top of the beam 52 further toward the point where each bracing rod 58, 60 is anchored to the floor 59.
In a first embodiment, the plate 16 for coupling to the floor 59 includes an angled portion at a 45° angle and the rod 60 has a bottom portion 60a coupled to the floor plate 16 with a rigid 45° connection. This may be done by welding, clamping, or any other technique currently used in and acceptable in the prior art. Since the base plate angle is set at 45°, the location for clamping the clamp assembly 61 and the length of the rod 60 are selected in order to assure a vertically oriented beam 52 that is plumb in the desired direction. In
In an alternative embodiment the angle of the bracing rod 58 can be also adjusted by pivoting the bottom portion 58a of the bracing rod to change the angle α between the bottom portion 58a of each bracing rod 58 and the floor 59. For example, when it is desired to move the top of the beam 52 closer to the point where the bracing rod 58 is anchored to the floor 59, this is done by increasing the angle α of the bracing rod 58. When it is desired to move the top of the beam 52 further away from the point where bracing rod 58 is anchored to the floor 59, this is done by decreasing the angle α of bracing rod 58. An adjustable floor bracing system 64 is used to increase or decrease the angle α of bracing rod 58, and various embodiments for such a design are discussed further below with respect to
As shown in
In one embodiment, first and the second fastening rods 70, 72 may be positioned to firmly retain a respective third and fourth side 52c, 52d of the beam within the first brace assembly 54. For this embodiment, the first fastening rod 70 is adjacent to and in contact with the third side 52c of the beam 52 and, the second fastening rod 72 is adjacent to and in firm contact with the fourth side 52d of the beam 52. To advantageously accommodate differently sized beams 52, each of the first and the second fastening rods 70, 72 are slidably mounted within a first opening 74 in the first head bracket 66 and a second opening 76 in the second head bracket 68, such that the distance between the first and the second fastening rods 70, 72 can vary.
In the example shown in
It is not necessary for the fastening rods 70, 72 to be in contact with the beam 52. Generally, the compression force of the clamp 65 will hold the beam in position and the fastening rods 70, 72 will be adjacent to, but spaced some short distance away from, the beam 52. Thus, in a preferred embodiment, the fastening rods 70, 72 do not contact the beam 52.
An adjustable locking system 80 is used to easily maintain the desired position of each of the fastening rods 70, 72 firmly against the beams 52. The example provided in
In operation, as the bracing rod 58 of the first brace assembly 54 is moved in the “x” direction, the top portion of the beam 52 also moves in the “x” direction and this movement enables a worker to plumb the beam 52. This is because the beam is clamped by clamp 65 and the connection between the bracing rod 58 and the first brace assembly 54 is rigid. Thus, as the bracing rod 58 is moved in the “x” direction, the clamp assembly 56 moves, as to the first and the second fastening rods 70, 72, causing the beam 52 positioned between them to also move in the “x” direction.
The second brace assembly 56 is composed of the same components as the first brace assembly 54, however, the orientation of the second brace assembly 56 on the beam 52 is such that the first head bracket 66 is positioned adjacent to the third side 52c of the beam 52, and the second head bracket 68 is positioned opposite the first head bracket 66 and adjacent to the fourth side 52d of the beam. Thus, the first and the second fastening rods 70, 72 are positioned adjacent to the first and the second side 52a, 52b of the beam 52, respectively. In this way, as the first and the second sides 52a, 52b of the beam 52 are clamped by the clamp assembly 65 and positioned between the first and the second fastening rods 70, 72 of the second brace assembly 56, when the bracing rod 60 of the second brace assembly 56 is moved in the “z” direction, the top portion of the beam 52 also moves in the “z” direction. Thus, by moving the bracing rod 60 of the second brace assembly 56 in the “z” direction, a worker can plumb the beam 52.
The turnbuckles permit fine tune adjustment of the beam's vertical orientation. By turning the turnbuckles just a few turns, or a fraction of a turn, the vertical position can be set with high accuracy, while permitting the mounting bracket to be at a variety of possible angles and not placing stress on the rod connection. Namely, if the floor bracket angle is set to a rigid position as is the case for bracket 16 of
Referring back to
The example shown in
Although the beam 52 shown in the above-mentioned figures is depicted with a square cross-section, the present invention is not limited to a particular type of beam and can be used on any number of beam types, such as round beams, I-beams, and tapered beams. In addition to a variety of beam shapes, the present invention may be used on beams made of any material, such as wooden beams, steel beams, composite beams, aluminum beams, and concrete beams.
The present invention is particularly helpful when the final orientation of the beam 52 is something other than vertical. For example, some architectural plans may call for a beam to be at a 45°, 30°, or some other angle. With the present invention, the beam can be temporarily held at any selected angle in a solid position until the building structure around the beam can be completed which holds it permanently in position.
From the foregoing it will be appreciated that, although specific embodiments of the invention have been described herein for purposes of illustration, various modifications may be made without deviating from the spirit and scope of the invention.
