Description
Technical Field
The utility model relates to a deformed steel bar adapting unit field especially relates to a double-end sleeve is connected to deformed steel bar.
Background
Screw-thread steel is a steel that is very commonly used in the building site, and the connection between two present screw-thread steels adopts welding or ligature to connect more, and the operation is got up the trouble, and it is inconvenient to dismantle, and joint strength is also not enough in addition, leads to at the bottom of the engineering efficiency, and the engineering quality is low.
Disclosure of Invention
The utility model aims to solve the technical problem that a double-end sleeve is connected to deformed steel bar is provided, simple structure for the mode of ordinary welding and ligature, promotes performance intensity greatly, connects convenient more fast, promotes production work efficiency.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a double-end sleeve is connected to deformed steel bar, includes cylindric main part, the inside of cylindric main part be provided with axial through hole, this axial through hole's both ends are provided with thread portion, link to each other through transition connecting portion between the thread portion at both ends, thread portion adopt trapezoidal thread, adjacent trapezoidal thread of thread portion between the thread groove width of thread groove be 6.2mm-6.4mm, the pitch between one side upper end of thread groove and one side upper end of adjacent thread groove is 10mm, the thread groove contained angle between the both sides inclined plane of thread groove between the trapezoidal thread is 90.
Furthermore, the outer side end of the thread part is provided with a guiding conical surface.
Furthermore, the included angle a between the conical surfaces at the two sides of the guiding conical surface is 90-120 degrees.
Has the advantages that: the utility model relates to a deformed steel bar connection double-end sleeve, simple structure, intensity is big, for the mode of ordinary welding and ligature, promotes performance intensity greatly, connects convenient more fast, promotes production work efficiency.
