Self-locking tube-gripping straight-cutting connector for reinforcing steel bars

Abstract

The invention provides a self-locking tube-gripping straight-cutting connector for reinforcing steel bars. The self-locking tube-gripping straight-cutting connector comprises a first connector, a second connector and a first elastic snap ring, wherein the first connector comprises a plug-in raised head, a connecting shaft and a first sleeve allowing a first reinforcing steel bar to be connected, the connecting shaft is connected to the plug-in raised head and the first sleeve in the axial direction, and the radial size of the plug-in raised head is larger than that of the connecting shaft; the second connector comprises a spigot and socket pipe and a second sleeve allowing a second reinforcing steel bar to be connected, a first end of the spigot and socket pipe is connected to the second sleeve, a limiting cavity is formed in the spigot and socket pipe, a first inserting hole is formed in a second end of the spigot and socket pipe and communicates with the limiting cavity, a positioning block is arranged in the limiting cavity, and a positioning groove is formed in the positioning block; and the first elastic snap ring is arranged in the limiting space and positioned between the positioning block and the first inserting hole, the plug-in raised head is inserted into the positioning groove, and the first elastic snap ring is arranged on the outer side of the connecting shaft in a sleeving manner and propped against the plug-in raised head. The problem that the construction efficiency is low when a traditional reinforcing steel bar connecting sleeve or connector is used in reinforcing steel bar butting construction is solved.

Description

technical field [0001] The invention relates to a steel bar connection tool, in particular to a self-locking clamping type steel bar direct insertion joint. Background technique [0002] In the construction of reinforced concrete structures, the connection methods of steel bars include binding, welding and mechanical connection. In the current building construction, the steel mechanical connection joint is the most commonly used because of its better connection effect. The steel bar mechanical connection joint greatly improves the connection strength of the steel bar without destroying the bending resistance of the steel bar, and ensures the construction quality of the reinforced concrete structure. [0003] The common methods of steel mechanical connection joints include extrusion sleeves and threaded connection joints. Sleeve extrusion connection requires extrusion equipment and requires a certain operating space. The threaded joint is a joint with an internal thread, a...
