Description

  The present invention relates to a kind of reinforcing bar connector, and in particular, two fitting connection parts cover and hold the opposite joint-side outside of the two reinforcing bars, respectively, and further, the outer sleeve positions the two fitting connection parts in a simple manner. The present invention relates to a reinforcing bar connector that is assembled, saves assembly time and construction cost, has high frictional resistance, and has good tensile strength and seismic strength.

  As bridge heights increased and high-rise buildings became more common, the use of rebar connectors increased dramatically. In building and civil engineering processes, columns, beams, or continuous walls of foundation processes, such as reinforced concrete structures (RC) or steel reinforced concrete structures (SRC) structures, are generally connected using two connectors.

  Since general rebar length dimensions are limited to the production site and the place of transportation process, both have a fixed length range requirement, and the construction site extends the rebar length according to the connection method to meet the actual construction requirements. I have to deal with it.

  FIG. 9 is a known three-dimensional exploded view. This known reinforcing bar connector is formed by combining a sleeve A and a plurality of nuts B, and has a tooth screw A1 on the inner tube wall on the two sides of the sleeve A, and the sleeve. There are male threads A2 on the outer pipe wall on the two sides of A, and inclined pipes A3 are processed on the inner and outer circumferences of the two sides of the sleeve A, respectively, and there are a plurality of split grooves A4 on the two inclined pipes A3. .

  The left and right rebars C are inserted from the two sides of the hollow sleeve A, and the two nuts B are screwed into the male screws A2 on the two sides of the sleeve A, and the inclined female screws provided inside the two nuts B are inserted. When the screw B1 is screwed toward the center of the sleeve A and the inclined female screw B1 is screwed with the male screw A2 of the inclined tube A3, the female screw B1 rotates to bias the inclined tube A3 inward, and the two teeth The left and right reinforcing bars C are clamped by the screw A1.

This reinforcing bar connector has an effect of connecting the left and right reinforcing bars, but has a partially incomplete defect as follows.
(1) This known reinforcing bar connector has left and right reinforcing bars C sandwiched by tooth screws A1 in the cylindrical wall on the two sides of the sleeve A, and a line contact formed by the surfaces of the tooth screws A1 and the reinforcing bars C. Due to the pinching method, the frictional resistance is insufficient, so that the rebar C cannot meet the stress requirements such as the tensile strength, the tensile strength cannot be maintained, and the seismic strength is lowered.
(2) In this known reinforcing bar connector, only by continuously rotating two nuts B at the two ends of the sleeve A, the female screw B1 of the nut B is completely screwed into the male screw A2 at the two ends of the sleeve A. Thus, by completely rotating the nut B to the predetermined position, the two-end toothed screw A1 can be reliably positioned by sandwiching the left and right reinforcing bars C. Such a rotational screwing method makes the assembly process cumbersome and takes construction time.

  Therefore, how to solve the above-mentioned well-known drawbacks and inconveniences is the direction in which related companies want to improve their research.

  In light of the above-mentioned problems and shortcomings, the present inventor collected related materials, conducted various evaluations and considerations, and made many years of experience in this industry, and made trial manufactures and improvements.
