Patent number: 6666636Abstract: A drop-in anchor includes a sleeve having a threaded region having an internal thread formed therein and a split region having at least two longitudinal channels formed therein. The channels define sections. The split region has inwardly tapered inner walls. A plug is configured for engagement with the sleeve at the split region. The plug has a top surface and defines a tapered shape. A bolt having a threaded portion and a through-bore extending longitudinally therethrough, is configured for threaded engagement with the sleeve threaded region. A setting member is configured for insertion into the bolt bore. The setting member engages the plug top surface and a force exerted on the setting member drives the plug into the sleeve split region so as to urge the split region sections axially outwardly. A method for securing the anchor in the opening in the structure is also disclosed.Type: GrantFiled: April 23, 2002Date of Patent: December 23, 2003Assignee: Illinois Tool Works, Inc.Inventors: Jeffrey C. Warmolts, Timothy M. Moran

Patent number: 6420458Abstract: A chemical anchoring adhesive having a solid, putty-like consistency includes two parts in direct contact with each other along an interface. The first part includes about 20-45% by weight of an epoxy resin, about 10-40% by weight of a first particulate filler having an oil absorption value of at least about 30, and about 40-65% by weight of a second particulate filler, at least about 70% of which has a U.S. Sieve size between 16 and 45. The second part includes about 5-20% by weight of an aliphatic amine compound, about 0.1-15% by weight of a tertiary amine compound, about 1-23% by weight of a first particulate filler having the oil absorption described above, and about 52-87% by weight of a second particulate filler having the U.S. Sieve size described above.Type: GrantFiled: July 26, 2000Date of Patent: July 16, 2002Assignee: Illinois Tool Works, Inc.Inventors: James E.

Patent number: 6416256Abstract: A method of making and applying a chemical anchoring adhesive in the form of a highly viscous, self-contained rope or slug is provided. The rope or slug has an average cross-sectional area determined from a formula that takes into account the cross-sectional area of a borehole, the average cross-sectional area of an anchor pin to be inserted into the borehole, and a penetration factor which reflects penetration of the adhesive into the walls of the borehole. By selecting the proper area for the anchoring adhesive, the rope can be cut into slugs having depths equal to the depths of boreholes. When the slugs are inserted into the boreholes, and anchor pins are driven, the amount of adhesive provided by each slug will be just enough to completely fill the interstitial spaces between the anchor pin and inner wall of the borehole, accounting for penetration of some adhesive into the borehole wall.Type: GrantFiled: July 26, 2000Date of Patent: July 9, 2002Assignee: Illinois Tool Works Inc.Inventors: James E.

Patent number: 6402434Abstract: A method of applying a chemical anchoring adhesive to the interior of a borehole includes the steps of providing a highly viscous, self-contained slug of chemical anchoring adhesive, inserting the slug into the borehole, providing an anchor pin, and driving the anchor pin into the borehole using a driving tool that imparts rotary motion to the anchor pin. The adhesive slug includes a first part having a first color and including a resin, and a second part having a second color different from the first and including a curing agent. The rotary motion of the anchor pin mixes the first and second parts together to form a substantially homogeneous composition having a third color different from the first and second colors. The visual indication provided by the third color notifies the worker when the mixing is complete, saving time and money at the construction site while minimizing the occurrence of defective or insufficient mixing.Type: GrantFiled: July 26, 2000Date of Patent: June 11, 2002Assignee: Illinois Tool Works, Inc.Inventors: James E.

Patent number: 6403678Abstract: A rope of chemical anchoring adhesive useful in heavy construction applications includes first and second parts in continuous contact along an interface extending the length of the rope. The first part includes a resin and has a highly viscous, putty-like consistency. The second part includes a curing agent and has a highly viscous putty-like consistency. The rope can be cut into slugs at the construction site which are sized according to the depth of the borehole, into which the anchor pin is driven.Type: GrantFiled: July 26, 2000Date of Patent: June 11, 2002Assignee: Illinois Tool Works, Inc.Inventors: James E.

Patent number: 6291555Abstract: A chemical anchoring adhesive includes first and second parts each having a highly viscous, putty-like consistency. The first and second parts are joined directly to each other along an interface. The first part includes a resin, and the second part includes a curing agent. The anchoring adhesive does not require separate encapsulation of one or both parts, and can be formed and cut to desired sizes and quantities at any stage before insertion into a borehole.Type: GrantFiled: July 26, 2000Date of Patent: September 18, 2001Assignee: Illinois Tool Works IncInventors: James E. Surjan, Richard J. Ernst, Mark S. Timmerman, Cyndie S. Hackl, Jeffrey C. Warmolts, Eldridge Presnell
