FIELD OF THE INVENTION
This invention relates to the use of a split collar apparatus for interconnecting beams to columns in the construction of a building. The split collar apparatus comprises a collar that slide-ably engages with a column of the building frame and provides one or more sites to enable the attachment of a beam to the collar and thence to the column to which the collar is engaged.
BACKGROUND OF THE INVENTION
In the construction of a building, a moment frame is one architectural choice, where mo- ment frames have shear strength where the moment frame gets its shear strength capacity via the collective stiffness provided by the joints between vertical and horizontal members. Each joint is carefully designed to resist deflection in each joint and thereby collectively provide shear strength and shear capacity in the entire wall frame (thereby forming a truss). The moment frame distributes the shear loads throughout the structure with each joint providing a portion of the shear capacity. Thus, the shear loading is distributed much more evenly throughout the structure and individual connection requirements between the vertical columns and the horizontal beams are decreased compared to the connection strength required at braced bays of a braced frame.
BRIEF SUMMARY OF THE INVENTION
This invention relates to the use of a split collar apparatus to interconnect beams with columns in the construction of a building. Given the requirements of a moment frame architec- ture, the present split collar apparatus can be used to produce connections between beams and columns that supply the collective stiffness provided by the joints between vertical and horizon- tal members.
The split collar apparatus comprises a collar that includes two segments, a lower segment and an upper segment that slide-ably engage with a column of the building frame and provide one or more sites to enable the attachment of a beam to the collar, when the beam is mounted between the lower segment and the upper segment of the collar, and thence to the column of the building frame to which the collar is secured. Each of the lower segment and the upper segment includes one or more flanges, oriented to extend in a direction that is perpendicular to the col- umn, and that contain holes to match corresponding holes formed in the beam which is to be at- tached to the collar. At least the lower segment of the collar also has formed therein at least one hole that corresponds to a mating hole that is formed in the column, so a fastener inserted through the holes in the collar and in the column enable the attachment of these two components, to thereby position the beams at the corresponding vertical level on the column, when they are mounted on the flanges of the collar.
The use of bolted connections facilitates fine adjustment of the alignment of the beams and columns, and the segments of the collar can thence be welded to the column of the building frame (and/or have material, such as a liquid grout, inserted between the collar and column) to secure the final alignment of these elements and provide a rigid set of joints. In addition, the col- lar can be used to interconnect two stacked columns, each secured to a respective one of the up- per segment and the lower segment of the collar. Thus, the collar funct ions both to support beams and secure columns in a stacked fashion.

DETAILED DESCRIPTION OF THE INVENTION
This invention relates to the use of apparatus to interconnect beams to columns in the construction of a building. Figure 2 illustrates the basic structure of the columns and beams in the construction of a building frame 200. This structure includes a plurality of vertically oriented columns 201 - 204 which are interconnected by horizontally oriented beams 211 - 213, 221 - 230. The interconnection of these elements is effected by split collars 241 - 246.
In order to illustrate the details of the Split Collar Bolted Frame Connector (for simplicity of description it is termed "split collar 101” herein). Figure 1 is used as an example of an imple- mentation of the split collar 101 that can be used in the construction of the Building Frame 200 shown in Figure 2. The apparatus comprises a split collar 101 that slide-ably engages with a col- umn 102 of a section 100 of building frame 200 and provides one or more sites to enable the at- tachment of one or more beams 111-114 to the collar 101 and thence to the column 102 to which the collar 101 is secured. The Figures use box beams to illustrate the functionality of the split collar 101, but these beams can alternatively be other well-known beam configurations, such as I-Beams (wide flange beams), C - channel, and L shaped beams.
In particular, Figures 1 and 5 illustrate a perspective view and an exploded view, respec- tively, of the split collar 101. The split collar 101 includes two segments, a lower segment 103 of the split collar 101 and an upper segment 104 of the split collar 101 that slide-ably engage with a column 102 of the building frame 100 and provides one or more sites to enable the at- tachment of beams 111- 114 to the split collar 101, when secured between the lower segment 103 of the split collar 101 and the upper segment 104 of the split collar 101, and thence to the column 102 of the building frame 100 to which the split collar 101 is secured. Each of the lower segment 103 of the split collar 101 and the upper segment 104 of the split collar 101 consists of a tubular segment which slide-ably engages with the column 102 of the building frame 100 and further includes one or more flanges 131 - 134 and 141 - 144, oriented to extend in a direction that is perpendicular to the column 102, and each of which contain holes 131 A - 13 IF through 134A - 134F and 141A - 141 F through 144A - 144F to match corresponding holes 181- 184 formed in the beams 111 - 114 which is to be attached to the split collar 101. The flanges can be of various shapes, from circular disks to the rectangular shapes illustrated herein.
At least the lower segment 103 has formed therein at least one hole (which has bolt 163 inserted therein as shown in Figures 1 , 5A, 5B) that corresponds to a mating hole (not shown) that is formed in the column 102 of the building frame 100, so at least one fastener 163 inserted through the holes 162 in the split collar 101 and in the column 102 of the building frame 100 en- able the attachment of these two components, to thereby position the beams 111 - 114 at the cor- responding vertical level on the column 102 of the building frame 100, when they are mounted on the flanges 131 - 134 and 141- 144 ofthe split collar 101.
In addition, the lower segment 103 of the split collar 101 can be welded 172 to the col- umn 102 of the building frame 100 to ensure a rigid connection between these elements by sup- plementing the bolt attachment of these two elements. Furthermore, the use of the term“bolted” is simply an illustration of one means of interconnecting elements and is not intended to be limit- ing in its scope, as understood by those of ordinary skill in the constructions arts.
The beams 111 - 114 each have at least one opening 191-194 formed in at least one side or top/bottom surface thereof, proximate the distal end of the beam 111- 114 to enable a worker to secure a fastener (not shown), such as a bolt, that is inserted in the collection of holes formed in the top surface and bottom surface of the beam 111 - 114 proximate the distal end of the beam 111 - 114. These fasteners also traverse the mating holes 131A - 13 IF through 134A - 134F formed in the flanges 131 - 134 and mating holes 141A - 141F through 144A - 144F formed in the flanges 141 - 144 of the collar 101. These bolts, as they are tightened, function to secure the proper alignment of the beams 111 - 114 and split collar 101 making fine adjustments as they are tightened as is well known in the construction arts.
An additional, optional, set of holes 164, 151 can be formed in the upper segment 104 of the split collar 101 and column 105 of the building frame 100, so at least one fastener 161 insert- ed through the holes 164 in the split collar 101 and 151 in the column 102 of the building frame
100 enable the attachment of these two components, to thereby supplement the function of the lower segment 103 of the split collar 101 to position the beams i l l - 114 at the corresponding vertical level on the column 105 of the building frame 100, when they are mounted on the flang- es 131 - 134 and 141 - 144 of the split collar 101. This set of holes 164, 151 and fastener 161 may be considered redundant, since the beams 111 - 114 are fastened to the flanges 131 - 134 of the lower segment 104 of the split collar 101 and thence to the column 102 of the building frame 100. Furthermore, the upper segment 104 of the split collar 101 can be welded 171 to the col- umn 102 of the building frame 100 to ensure a rigid connection between these elements by sup- plementing the bolt attachment of these two elements. Another option is to use liquid grout in- serted between the segments of the split collar 101 and the columns 102, 105 to ensure a rigid connection between these elements by supplement ing the bolt attachment of these two elements. Multiple Segment Columns
In addition, as shown in Figure 5B which illustrates an exploded view of the split collar
101 connecting two vertically stacked columns, the split collar 101 can be used to interconnect two stacked columns 102, 105. Thus, the split collar 101 functions both to support beams 111 -
114 and secure columns 102, 105 in a stacked fashion. Figure 5B illustrates a perspective view of the split collar 101 with segments of the beam 111- 114 inserted therein and the lower segment 103 and the upper segment 104 of the split collar 101 separated by sliding the upper segment 104 vertically on the column 105 to expose a site where a first segment 105 of a column is to be joined to a second segment of a column 102 by welding the two together at this site. Once the weld is completed, the exposed surfaces of the column 105 and the column 102 can be smoothed by grinding or any other technique to enable smooth movement of the upper segment 104 on the column 102, with this weld 106 being covered by the upper segment 104 of the split collar 101 when lowered into place on top of the beams 111 - 114. The split collar connection therefore serves as the column splice joint between vertically adjacent columns 105, 102. While a mostly “bolted” field connection is desired and designed in the split collar connection, it is not neces- sarily 100% a bolted connection. There is a considerable shop fabrication via welding implied in the design, but this is viewed as tolerable as quality control and inspection is reasonable to ac- complish in a factory/shop setting. In contrast to this, field welding is much more difficult to control, particularly at scale. So the Split Collar Bolted Frame Connector shows a mostly bolted connection in the field to make this tolerable. There are still some field welding steps involved, but they are relatively minor and do not constrain the primary assembly process or singularly de- termine the structural integrity of the building.
It is worth noting that the tube of the upper Collar segment 104 can be longer than the lower Collar Tube 103. This is because the tube of the upper Collar segment 104 also functions as a Mating Tube. This means that the tube of the upper Collar segment 104 is empty at a par- ticular level during framing of a building, such that new Wall Frames can then be set into place by dropping them into the empty spaces of the tube of the upper split collar segment 104 be- low. So the split collar design is a 4 Way Connector of primarily bolted configuration, but it is also concurrently an integral Mating Tube for subsequent assemblies to be aligned and affixed to the partially framed structure. This is illustrated in Figure 6 which provides a perspective view of an alternative configuration of the Split Collar Bolted Frame Connector connecting two verti- cally stacked columns. Here, the upper segment 104 of the split collar 101 functions both to se- cure the horizontal beams 111-114 but also provide a locus to receive the lower end of vertically oriented column 105 which slides into the top opening of the upper segment 104 of split collar 101 to seat therein against the top of the existing lower column 102 at the site indicated by dotted line 601. Summary
The split collar apparatus interconnects beams to columns in the construction of a build- ing that incorporates a moment frame architecture. The split collar apparatus includes two seg- ments, a lower segment and an upper segment that slide-ably engage with a column and include one or more flanges, oriented to extend in a direction that is perpendicular to the column, and that contain holes to match corresponding holes formed in the beam which is to be attached to the collar. At least the lower segment of the collar has formed therein at least one hole that cor- responds to a mating hole that is formed in the column, so a fastener inserted through the holes in the collar and in the column enable the attachment of these two components, to thereby position the beams at the corresponding vertical level on the column, when they are mounted on the flanges of the collar.
