The strike assembly type fixing device for a shipyard according to the present invention is configured such that a protruding flange inclined downward is integrally formed with a fixture to form a single body at a portion where an upper end and a lower end of a fixture are connected to each other, and a packing ring is provided to be inserted into the lower end of the fixture in close contact with the protruding flange.

A locking structure includes a main body, a first combining portion, and a second combining portion. The second combining portion is disposed on an outer periphery of the main body. The first combining portion is connected to a bottom portion of the main body. A chamber is formed inside the first combining portion. At least one slot is formed on a side wall or a bottom wall of the first combining portion and communicated with the chamber. The chamber is at least partially filled with the workpiece via the at least one slot, and the workpiece is at least partially combined with an inner side and an outer side of the first combining portion, so as to combine the locking structure with the workpiece tightly.

A self-piercing fastener having a planar base plate with a top, a bottom, and a peripheral edge. A plurality of prongs are fixed to the peripheral edge and extend downward past the bottom of the baseplate. Each of the prongs has a central axis and an arrowhead-shaped barb fixed to a distal end. Each barb has opposed front edges extending from the tip, and opposed back edges oriented at a reverse acute angle relative to the central axis of the prong. Each barb is adapted to fixedly embed in the interior of a panel to which the fastener is affixed.

A hole punch and a method for piercing a workpiece wherein a hole punch includes a sheet metal part and a piercing body attached thereto which carries out the piercing function and which is provided with a thread cylinder or can be provided with a thread cylinder, for example by pressing a threaded pin into a centrally arranged passage of the hole punch, wherein the hole punch can also be formed in one piece as a piercing body with a sheet metal-like flange. Furthermore a method is claimed for the manufacture of the hole punch.

An aircraft joint between overlapping first and second components includes a fastener assembly. The fastener assembly includes a threaded fastener and a boss having an outer diameter and a threaded internal bore. The boss is fixedly attached to the second component at the overlap region. The first component has a through hole having a diameter sized to receive the outer diameter of the boss. The boss is received in the through hole from a first side of the first component. The fastener extends through the through hole from a second side of the first component opposite the first side. The fastener is threadably received in the internal bore of the boss and reacts against the second side of the first component to fasten the first component to the second component.

One aspect is an apparatus including an additively manufactured first component and a captive nut contained within the first component for interconnecting the first component to a second component. Another aspect is an apparatus including a first additively manufactured component having a hole and a second additively manufactured component having a socket. The apparatus further includes a pin having a head engaging a surface of the first component and a shaft extending from the head through the hole in the first component and into the socket of the second component. Another aspect is an apparatus including first and second panels. The apparatus also includes a bolt having a head and a shaft extending from the head and a nut located at a distal end of the shaft. The first and seconds panels may be sandwiched between the bolt and nut to interconnect the first and second panels.

A handle attachment assembly that includes first and second insert members, and a handle assembly that includes a cover and a main body portion. The main body portion includes a handle portion and first and second attachment portions extending from the handle portion. The cover is removably connected to the main body portion and the main body portion and the cover cooperate to define a handle interior. The first and second attachment portions include first and second attachment members, respectively. The first attachment portion and the first insert member are secured together by a first fastener, and the second attachment portion and the second insert member are secured together by a second fastener.

A hole punch and a method for piercing a workpiece wherein a hole punch includes a sheet metal part and a piercing body attached thereto which carries out the piercing function and which is provided with a thread cylinder or can be provided with a thread cylinder, for example by pressing a threaded pin into a centrally arranged passage of the hole punch, wherein the hole punch can also be formed in one piece as a piercing body with a sheet metal-like flange. Furthermore a method is claimed for the manufacture of the hole punch.

A cast-in-place anchor assembly is disclosed for suspending objects below a metal deck. The assembly includes an anchor body and an anchor support. The anchor body includes a threaded opening. The anchor support includes a central member which, in use, extends from a first upper side of the metal deck to a second lower side of the metal deck. The central member further includes a connector. The central member also includes a biasing portion which cantilevers radially outward. The central member further includes a stopping member sized to be larger than a deck opening. An end of the anchor body is connected to a connector to conceal the threaded opening from poured concrete. The stop member flexes to pass through the opening in the metal deck and the stop member and the biasing member flexingly bias the anchor support into position relative to the metal decking.

A device and a method are provided for setting a press-in element into a workpiece at a predetermined location. The device includes main body; a fixing unit, which is attached to the main body and which is designed to fix the workpiece; and a processing unit, which is attached to the main body and includes: a boring unit, which is designed to create a bore in the workpiece fixed by the fixing unit; and a pressing unit, which is designed to press a press-in element into the bore. The method fixes the workpiece; creates a bore in the workpiece; positions a press-in element over the bore; and presses the press-in element into the bore, wherein a single device is used to carry out the method.
