Column/beam interconnect nut-and-bolt socket configuration
View Patent ↗Column/I-beam interconnect structure including an attaching plate joined to an I-beam end. This plate possesses, along its lateral margins, angularly oriented upper and lower through-passages, each characterized with a reception axis, and designed to receive, along that axis, portions of a hex nut-and-bolt set which is used to clamp together two adjacent, angularly related attaching plates. The socket portions, or outer chambers, of the through-passages are formed with spaced and generally parallel-planar upper and lower surfaces which act in these socket portions to restrain a received hex nut against rotation about its own rotational assembly axis which, in the socket portion, is coincident with the socket portion's reception axis. This arrangement uniquely allows for a structural configuration wherein laterally directed moment loads are transferred very closely relative to the elevations of such beams' flanges, and more specifically, as close as possible to key axes of force transmission such as those that lie laterally centrally in the planes of these flanges.
1. Beam-to-column attaching structure comprising
an angular-modularity, substantially planar plate having a pair of spaced, parallel-planar faces, one of which is anchorable at the end of an elongate structural I-beam to the beam's substantially planar central web and upper and lower, substantially parallel-planar flanges, where said plate has elongate, lateral edges, and is configured to be joined through said edges to the comparable lateral edges in a pair of angularly adjacent, other, like plates, thus to form therewith a portion of a collar adapted to wrap around the outside of an elongate structural column at a defined location along the length of the column, with the other face in the plate being adapted to face the outside of such a column, and
along each of said plate's said lateral edges, a row of angularly oriented through-passages, with each row lying along a line which will substantially parallel the plane of the central web in a beam having an end anchored to said one face in the plate, and with the through-passages in each row being non-uniformly spaced and organized into two, upper and lower groups which will lie clustered adjacent the upper and lower flanges, respectively, in an associated I-beam, with the spacings D 2 exiting between next-adjacent through-passages in each group being less than the spacing D 3 existing between the next-adjacent through-passages in the two groups,
each through-passage accommodating the reception and utilization of a hex nut-and-bolt assembly which is defined by an elongate assembly axis, and which is designed to participate in the angular joining of the plate to a next-adjacent plate, with each through-passage having a chamber which opens to said one face in the plate, and which includes a pair of spaced, parallel-planar surfaces adapted, with respect to any nut residing in the chamber, to engage the nut, thus to prevent rotation of that nut about its associated assembly axis.
2. The structure of claim 1 , wherein said surfaces in said chamber, with said plate anchored to the end of an I-beam, lie in planes that substantially parallel the planes of the I-beam's flanges.
