A chemical anchor bolt and cap assembly installable in a hole drilled in masonry to tightly fasten a fixture thereto and to resist loosening of the fastening should the masonry be subjected to vibratory or other external forces. The assembly includes a bolt having an externally-threaded cylindrical shank coated with a release agent and a thin-walled hollow cap having a non-cylindrical shape coupled to the end of the shank and extending therefrom in axial alignment with the shank. To install the assembly, the shank and the cap coupled thereto are inserted through a mounting hole in the fixture into the masonry hole in which is deposited an uncured epoxy that then surrounds the cap and the shank. When the epoxy hardens, formed therein is a female thread matching the release-coated male thread of the shank so that the bolt is now turnable, the cap being then embedded in the epoxy. As a consequence, formed in the masonry hole below the end of the shank is a hard epoxy column having a non-cylindrical cavity whose epoxy bank is defined and lined by the non-cylindrical cap to create a partial barrier to the unimpeded advance of the shank.

An enhanced strength screw-type, self-tapping masonry anchor for fastening a fixture or other attachment to masonry in which a hole is drilled to receive the anchor. The anchor is provided with a shank having a root section surrounded by at least one helical male cutting thread whose crest diameter exceeds the diameter of the hole whereby when the anchor is screwed into the hole, the cutting thread then cuts a female thread in the bank of the hole to mechanically retain the anchor therein to impart to the anchor a holding power that resists axial pull-out forces. Formed on the root in the helical land between successive convolutions of the thread is a ridge that is raised above the root to define a compacting zone between the ridge and the bank of the hole. Particulate debris produced by the cutting action is discharged into the land and forced into the compacting zone to create a dense mass that wedges the anchor in the hole and thereby enhances the holding power of the anchor.

A self-tapping, screw-type masonry anchor turnable into a hole drilled in masonry to fasten an object thereto, the anchor also being capable of being chemically retained in the hole to render it exceptionally resistant to pull out and vibratory forces. The anchor includes a head engageable by a tool to turn the anchor into the hole and a shank extending from the head surrounded by at least one helical cutting thread whose crest diameter exceeds the hole diameter whereby as the anchor is turned into the hole, a mating thread is then tapped in its bank. Also surrounding the shank in the space between successive convolutions of the thread is a helical zone. The shank of the anchor is coated with a release agent, and when a charge of an uncured, flowable resinous adhesive is deposited in the hole and the shank is turned therein, this adhesive then fills the helical zone, the flowable adhesive acting to lubricate and cool the cutting thread as the shank is turned into the hole. When the adhesive cures and hardens, a chemical barrier is formed in the zone which is bonded to the bank of the hole but not to the shank. Thus the anchor is mechanically retained in the hole by the cutting thread and chemically retained therein by the hardened barrier, yet the anchor can be turned out of the hole to unfasten the object from the masonry.

A chemical anchor bolt and cap assembly installable in a hole drilled in masonry for fastening an object thereto The threaded shank of the bolt and the hollow cap extending from its end are inserted into the hole, causing an uncured bonding agent deposited in the hole, such as an epoxy, to surround the cap and the shank. When the epoxy hardens the cap is then embedded in the epoxy to create a void below the end of the shank. Cast in the epoxy surrounding the shank is a female thread that complements the shank thread. To permit the bolt to turn and cause the end of the shank to advance into the void and thereby tighten the fastening, the threaded shank has coated thereon a releasable barrier layer that acts to masks surface irregularities in the shank thread and to slightly space the shank thread from the female thread. As a consequence, the female thread cast in the epoxy is functionally free of irregularities and is loosely intermeshed with the shank thread whereby the bolt can then be easily turned.

A fail-safe anchor bolt assembly installable in a pre-drilled hole in masonry to fasten a fixture or other object thereto, the assembly remaining securely anchored even should the hole later be enlarged as a result of a crack developed in the masonry. The assembly includes a bolt having a head engageable by a torque tool to turn the bolt and a shank extending from the head loosely encircled by an expansible shell whose normal outer diameter is close to that of the drilled hole. Threadably received on the end of the shank adjacent the shell is a wedge nut having a generally conical frustrum shape defining a leading end followed by a leading portion which merges with a compressible trailing portion terminating in a trailing end, the leading portion having a maximum diameter close to the diameter of the drilled hole and the compressible trailing portion having a normal maximum diameter greater than the diameter of the drilled hole. When the assembly is installed in a drilled hole, the leading portion of the nut enters into and acts to expand the shell against the wall of the hole to provide an anchoring force. But should a crack later develop in the masonry resulting in an enlargement of the drilled hole, the trailing portion then enters the shell to further expand it to maintain the anchoring force.

411386

A self-tapping, screw-type anchor capable of being turned into a hole drilled in masonry whose hardness renders the wall of the hole highly resistant to a tapping action. The anchor includes a thread forming a helical ridge on the root of the anchor, the thread having a profile defining a pair of opposing curvilinear flanks rising above the root and converging toward a crest. The curvature of the flanks which is preferably hyperbolic, creates a crest having a small included angle adapted to penetrate the wall of the hole, the crest being supported on a relatively broad base that merges with the root to firmly secure the thread thereto and thereby prevent deformation or mutilation of the thread as the anchor is being turned into the hole.

A cartridge strip magazine for successively feeding cartridges into the breech of a powder-actuated fastener setting tool. When a cartridge in alignment with the breech is fired, the resultant expanding gas acts to propel a drive piston to launch a fastener. The inlet to the breech is provided with a frusto-conical upper entry section and an inwardly offset frusto-conical lower section having the same slope as the upper section. The magazine is molded of a strip of resilient plastic material having a row of noses projecting therefrom, each nose socketing a cartridge and being adapted to nest within the inlet of the tool breech. Each nose is formed with an outer wall having a frusto-conical lower section which when the nose is nested within the breech abuts and conforms to the lower section of the breech, and an outwardly-offset frusto-conical upper section that then abuts and conforms to the upper section of the breech.

A centering sleeve and overflow ring assembly adapted to facilitate proper installation in a hole drilled in masonry of a stud for fastening a fixture or other object to the masonry. Deposited in the hole is a charge of a flowable bonding agent which when cured then anchors in place the stud inserted in the hole. The ring is preferably formed of a flat, tearable material and is seated on the masonry in registration with the hole. The sleeve which is snugly nested in the upper end of the hole includes inwardly-directed centering means that engage the stud inserted in the hole to maintain the stud centered therein while providing a flow passage between the stud and the sleeve. When the inserted stud plunges into the charge of bonding agent, the agent then rises in the hole and passes through the flow passage in the sleeve to overflow onto the ring. After the overflow accumulated on the ring cures and hardens, it can then be discarded by tearing off the ring. The centering means may be arranged to retard gravity flow of the agent from the sleeve should the sleeve be nested in a hole drilled in overhead or vertical masonry, thereby preventing leakage of the agent from the hole.

A centering sleeve and overflow member assembly adapted to facilitate installation of a bolt having a head and a shank extending therefrom in a hole drilled in masonry having a diameter greater than that of the shank to fasten a fixture to the masonry. The fixture has a mounting hole in alignment with the masonry hole in which is deposited a charge of a flowable uncured bonding agent. The overflow member which rests on the fixture has an opening therein in registration with the mounting hole and the sleeve which fits in the mounting hole telescopes into the upper end of the masonry hole. The sleeve is provided with centering means which when the shank is inserted through the sleeve into the masonry hole and the bolt head then lies adjacent the fixture, then acts to maintain the shank coaxial with the sleeve and with the bank of the masonry hole below the sleeve to define an inner passage between the shank and the sleeve and an annular space between the shank and the bank. When the shank enters the masonry hole and plunges into the charge, the flowable agent is caused to rise in the annular space and through the inner passage in the sleeve to overflow onto the member placed on the fixture. When the agent cures and solidifies, it then chemically anchors the shank in the masonry hole, the solidified agent collected on the overflow member being then discarded to provide a clean fixture surface.
