  • Patent number: 10711820
    Abstract: A composite screw includes a tapping end portion that includes a circular bottom surface, a peripheral surface and a main thread. The peripheral surface extends from the circular bottom surface. The main thread is formed around the peripheral surface. A reception recess is recessed from the circular bottom surface and the peripheral surface. The main thread has a discontinuation where the reception recess opens at the peripheral surface. A rigid body and a weld material fill the reception recess. The rigid body has an outer surface and an auxiliary thread. The outer surface is exposed from the reception recess. The auxiliary thread is formed on the outer surface and connected to the main thread to fill the discontinuation.

  • Publication number: 20200182281
    Abstract: A method for producing a composite screw includes: providing a screw body a circular bottom surface, a peripheral surface and a main thread; processing the screw body to format least one reception recess indented upwardly from the circular bottom surface and inwardly from the peripheral surface; providing at least one composite unit including a weld material and a rigid body of high stiffness material; disposing the weld material in the at least one reception recess and subsequently inserting and moving the rigid body into the at least one reception recess; and melting the weld material to secure the rigid body to the screw body.

  • Publication number: 20180209138
    Abstract: A combined anchor and rebar assembly includes a rebar, a bolt head, an anchor bolt and a weld joint. The bolt head is formed integrally as one piece with an end of the rebar. The anchor bolt includes a threadless portion and a threaded portion. The threaded portion has a diameter smaller than that of the threadless portion and is formed with a screw thread. The weld joint joins another end of the rebar to the threadless portion in a manner that the rebar and the threadless portion are aligned along an axial line. The weld joint has a cross section larger than that of the threadless portion and projects radially from the rebar and the threadless portion. A method of producing the combined anchor and rebar assembly is also disclosed.

  • Publication number: 20180001396
    Abstract: A dust vacuuming drill device is adapted to be connected with a vacuum suction device by a socket, and includes a drill bit and a driven shank threadedly engaged with each other and cooperatively defining therein an internal dust passageway in communication with the socket for removing the dust generated during a drilling operation. The drill unit can be removed from the driven shank when the drill unit is broken so as to readily replace the drill unit without the need to detach the driven shank from the socket, which results in low operation and material costs.

  • Publication number: 20170145824
    Abstract: A reinforcement bar to be embedded in a concrete structure includes a rod segment, a self-tapping segment, and a head. The rod segment defines a central axis. The self-tapping segment extends integrally from one end of the rod segment along the central axis. The head extends integrally from the other end of the rod segment along the central axis, and is operable manually to rotate about the central axis so as to drive the self-tapping segment to drill into the concrete structure.
