Clamping Device For Deck Panels With Support Saddles

US Patent:
6453495, Sep 24, 2002
Filed:
Aug 31, 1999
Appl. No.:
09/387287
Inventors:
Dave A. Meggers - Topeka KS
Jerry D. Plunkett - Russell KS
Stephen R. Gill - Russell KS
Robert L. Hoback - Russell KS
Hugh S. Walker - Manhattan KS
Jon Held - Manhattan KS
Assignee:
Kansas Department of Transportation - Topeka KS
International Classification:
E01D 1912
US Classification:
14 73, 2482283, 24823121, 24823141
Abstract:
A clamping device for use with or without a support saddle includes upper and lower filler bars adapted to extend along the upper and lower surfaces of a tongue like connecting member on an upstream deck panel. A pair of clamping bars are operable by a pair of bolts which extend though the filler bars and tongue like member upon placement of the panel atop the underlying support beams. Upon tightening the bolt, the free ends of the clamping bars bear against the underside of the support beam with the bolt head urging the tongue like member against the top of the beam so as to mechanically connect the panel to the beam. A support saddle has a pair of sidewalls of a selected height to space the overlying deck panel from the support beam. The top wall of the support saddle may be inclined to cant the deck panel relative to the support beam.

Preassembled, Easily Mountable Strain Gage

US Patent:
5289722, Mar 1, 1994
Filed:
Apr 27, 1992
Appl. No.:
7/873756
Inventors:
Hugh S. Walker - Manhattan KS
Robert J. Dorgan - St. George KS
Assignee:
Kansas State University Research Foundation - Manhattan KS
International Classification:
G01B 716
US Classification:
73775
Abstract:
A prefabricated, easily installable strain gage assembly (10) is provided which includes an elongated synthetic resin substrate (12) having adhesive (16) applied to the majority of one surface thereof while leaving a handling tab portion (18) adjacent one end of the substrate (12). A strain gage unit (28) is secured to the adhesive-bearing surface of substrate (12). A strippable protective film (56) is placed in covering, protective relationship to the strain gage (28) and the adhesive surface of substrate (12). Preferably, the substrate (12), adhesive (16) and film (56) are substantially transparent, and the substrate (12) is provided with perpendicular alignment marks (55, 55a) which are strategically located relative to the strain gage unit (28). A relatively long hold-down region (42) forming a part of the substrate (12) is provided between the handling tab portion (18) and strain gage unit (28), so that, upon initial visual alignment of the assembly (10) on a test surface ( 60), the film (56) may be partially removed to allow temporary adherence of the region (42) to the surface (62). This insures maintenance of the gage alignment and permits subsequent complete removal of film (56), application of bonding materials (68, 70, 72) to the strain gage unit (28) and surface (62), full lay-out of the substrate (12) on the surface (62), and subsequent substrate removal.
