Abstract
A coupling device for coupling reinforcing bars used in structural concrete comprising an elongate tubular body for receiving bar end portions, a plurality of engagers being adjustably positioned through the elongate tubular body, the coupling device being characterized in that the plurality of engagers are configured with a plurality of different end portions being configured for a different engaging of the reinforcing bars.
Claims40
A coupling device for coupling reinforcing bars used in structural concrete comprising:
- an elongate tubular body for receiving end portions of said reinforcing bars;
- a plurality of threaded engagers being adjustably positioned through threaded holes in said tubular body;
- said coupling device being characterized in that:
- said plurality of engagers are configured with a plurality of different types of end portions for engaging said reinforcing bars;
- wherein said different types of end portions have different end shapes that are configured for different types of respective engagings of said reinforcing bars.
A coupling device for coupling bars comprising:
- a sleeve-like body for receiving said bars;
- a plurality of threaded engagers being adjustably positioned through threaded holes in said sleeve-like body;
- said coupling device being characterized in that:
- at least one of said plurality of engagers comprises a first type of end portion having a first end shape, configured for a first type of engaging of said bars;
- and
- at least one of said plurality of engagers comprises a second type of end portion having a second end shape, configured for a second type of engaging of said bars.
A coupling device for coupling bars comprising:
- a sleeve-like body for locating over and about portions of said bars;
- a plurality of threaded engagers positioned though threaded holes in said sleeve-like body, said engagers being positively adjustable through said sleeve-like body;
- said coupling device being characterized in that:
- said plurality of engagers are different types of engagers having different end shapes for different respective types of engagings of said bars.
A method of coupling reinforcing bars used in structural concrete comprising:
- receiving end portions of said reinforcing bars in an elongate tubular body;
- adjustably positioning a plurality of threaded engagers through threaded holes in said tubular body;
- said method being characterized by:
- engaging said reinforcing bars with a plurality of different types of end portions of said plurality of engagers, said different types of end portions having different end shapes being configured for different respective types of engagings of said reinforcing bars;
- and
- coupling said reinforcing bars by said different types of engaging of said reinforcing bars by said different types of end portions, to different extents of bar penetration.
