Embodiment Construction
[0046] Figure 1 to Figure 8 An embodiment of a one-touch rebar coupling according to the invention is shown in .
[0047] Referring to the accompanying drawings, a one-touch steel bar coupling 10 according to the present invention is used to connect steel bars to each other when reinforcing bars in the construction of civil or concrete buildings 1, and has a coupling body 20, wherein the coupling body 20 forms There is a hollow part 24 with a first tapered part 21 and a second tapered part 22, the first tapered part 21 and the second tapered part 22 are used to insert the first steel bar 310 and the second steel bar 310 to be connected from both sides. The first insertion port 21a and the second insertion port 22a side of the reinforcement bar 320 are gradually expanded, and the component input opening 25 is formed on the outer peripheral surface of the coupling body 20 . The coupling body 20 has a first tightening unit 30 and a second tightening unit 40, wherein the first t...

The one-touch rebar coupling according to the present invention has a coupling body, a first tightening unit, a second tightening unit, a support member, a support member fixing portion, and a spring, wherein the coupling body is formed with a first tapered portion and the hollow part of the second tapered part, the first tapered part and the second tapered part gradually expand from the insertion openings on both sides for the insertion of steel bars, and the outer peripheral surface of the coupling body is formed with a part input port , the first tightening unit is inserted into the first tapered portion of the hollow portion through the component input port of the coupling body, and the second tightening unit is inserted into the second tapered portion of the hollow portion through the component input port of the coupling body. In the part, the support member is used to support the end of the steel bar provided and joined inside the coupling body, the support member fixing part fixes the support member with respect to the coupling body, and the springs are respectively supported by the support members to The first tightening unit and the second tightening unit are elastically biased toward the first tapered portion and the second tapered portion, respectively.
Description
technical field [0001] The present invention relates to rebar couplers, and more particularly, to a one-touch rebar coupler with improved coupler bodies and rebar support structures for connecting rebars in the construction of buildings. Background technique [0002] Generally, concrete is a composite composition composed of cement, sand, gravel, water, etc. in an appropriate proportion. Although its compressive strength is relatively high, compared with the compressive strength, its tensile length is relatively low, so it is prone to Cracking properties. In order to reinforce the strength of the concrete as described above (compensate for the tensile length), steel tendons (reinforcing bars) are placed in the form (Formwork) in which the concrete is poured. [0003] Existing reinforced concrete structures are not only capable of constructing various forms of structures due to their excellent compressive and tensile strengths, but also widely used in various architectural a...
