In particular, while reducing the structural members of the reinforcing bar connector, simply tighten the fixing bolts, and the spikes protruding from the end faces of the fixing bolts penetrate the outer circumferential surface of the reinforcing bar. The present invention relates to a reinforcing bar structure that is tightly fastened and fixed to each other.
일반적으로 건축물의 시공시에는 건축설계도에 따라 건축물의 들보, 벽체, 기둥 등의 거푸집을 설치하고, 그 속에 철근을 배근(配筋)하여 콘크리트를 타설한 후, 일정기간동안 양생시켜 탈형(脫型)하면 철근콘크리트 구조물이 완성된다.In general, when constructing a building, formwork such as beams, walls, and pillars of the building is laid according to the architectural plan, reinforcing steel in it, placing concrete, curing it for a certain period of time, and demoulding it. ) Will complete the reinforced concrete structure.
철근콘크리트 구조물 속에 배근된 철근은 휨모멘트에 의한 인장 또는 압축응력을 부담하게 되는 것으로, 표면에 마디와 리브가 있는 이형철근과 표면에 마디가 없는 원형철근 등이 있으며, 길이는 3.5m~10m 사이의 일정한 규격으로 생산된다.The reinforcement reinforced in the reinforced concrete structure bears the tensile or compressive stress due to the bending moment, and there are deformed steel bars with ribs and ribs on the surface, and circular bars without nodes on the surface, and the length is between 3.5m and 10m. Produced to a certain standard.
상기 일정한 길이로 규격화되어 생산되는 철근은 거푸집의 폭과 높이보다 길이가 짧으면 한개 이상의 철근을 이어 붙인 후 거푸집 속으로 배근을 하게 된다.If the reinforcing bars are standardized to a certain length and are shorter than the formwork's width and height, the reinforcing bars are connected to one or more reinforcing bars.
철근의 연속성은 매우 중요한 것으로, 실제 현장에서 일정규격의 제품을 사용하므로 필연적으로 철근을 상호 이음하여 사용할 수 밖에 없는 실정이다.The continuity of the reinforcing bar is very important, and since the product of a certain standard is used in the actual site, it is inevitably used to connect the reinforcing bars.
철근의 연결방법에는 철근과 철근을 겹쳐서 연결하는 겹이음, 용접에 의한용접이음, 기계식 나사이음 등이 있는 바, 이하 기존의 철근연결방법에 대해 간단히 살펴보기로 한다.The connection method of rebars includes overlapping reinforcing bars and reinforcing bars, welding joints by welding, mechanical screw joints, and so on.
상기 철근연결방법중 겹이음은 현장여건과 숙련도에 의해 이음부분을 조절하면서 작업할 수 있어 대부분의 공사현장에서 채택하고 있으나, 철근연결부위를 소정의 길이로 겹쳐서 0.9mm이하의 철선으로 여러 곳을 묶어주기만 하므로 이음부위가 불안정하여 기계적 성질을 보장할 수 없으며, 직경이 큰 철근의 이음부분은 겹쳐진 철근의 부피로 인해 콘크리트 주입이 어렵고, 철근이 1m 정도 겹쳐지게 되므로 철근의 막대한 손실을 초래하는 단점이 있다.Among the reinforcing bar connections, the joints can be controlled while adjusting the joints according to the site conditions and proficiency, so most construction sites are adopting them. It is not easy to guarantee the mechanical properties because the joint is unstable because it is only tied, and it is difficult to inject concrete due to the overlapped reinforcing bar's volume. There is this.
또한, 용접이음의 경우는 고온의 열이 가해지는 용접부 주변의 철근허용응력이 감소하고, 특히 고강도 철근은 이음부 주변의 허용응력이 급격히 약화되어 치명적으로 철근의 강도가 낮아지며, 용접작업이 까다로워 숙련공이 아니면 시공시간이 많이 소요되는 단점이 있다.In addition, in the case of welded joints, the allowable stress of the reinforcement around the welded part is reduced, especially in the case of high strength reinforcing bars, the allowable stress around the joint is weakened rapidly, and the strength of the reinforcement is fatally lowered. Otherwise, there is a disadvantage that a lot of construction time.
한편, 철근의 기계적 나사이음은 상기 겹이음과 용접이음의 단점을 개선한 철근연결방법으로서, 철근 단부를 나사가공하여 커플링과 너트 등으로 체결시키는 것인 바, 상기 나사이음은 인장, 압축, 휨, 비틀림 등 기계적 성질이 우수하고 전체길이가 일정하므로 정밀시공을 할 수 있다.On the other hand, the mechanical screw joint of the reinforcing bar is a reinforcing bar connection method to improve the shortcomings of the lap joint and the weld joint, the end of the rebar is screwed to the coupling and coupling, such as nuts, the screw joint is tension, compression, It has excellent mechanical properties such as bending and torsion, and its overall length is constant, so precise construction is possible.
그러나, 나사부분의 철근 단면적 감소로 응력이 약해지는 단점과, 이음부의 위치와 길이가 정확해야 하므로 가공 정밀도가 높아야 하는 등 시공이 까다롭고, 철근 단부의 나사가공작업 후 한쌍의 쐐기, 너트 및 양면볼트 등을 조립해야 하는등 철근 연결작업이 복잡하고 구성부재가 많아 비경제적인 단점이 있다.However, it is difficult to construct, such as the weakness of stress due to the reduction of the cross section of the threaded part, and the exact position and length of the joint part, which requires high machining accuracy. Rebar connection work is complicated, such as the need to assemble bolts, there are a lot of constituent members are uneconomical disadvantages.
본 고안은 상기와 같은 종래의 철근연결구조의 문제점을 해결하고자 안출한 것으로, 철근의 외경보다 큰 직경의 삽입공을 형성하고, 중앙부에는 스토퍼를 결합하며, 단면부에 스파이크가 돌출형성된 수개의 고정볼트를 각각 결합한 간단한 구성의 연결구를 마련하여, 상기 연결구의 삽입공 양측으로 철근의 끝부분이 각각 스토퍼에 맞닿여 멈추도록 삽입하고, 고정볼트를 조여 스파이크가 철근의 바깥둘레 표면을 파고들어 고정되도록 하므로서, 철근과 철근의 이음부를 긴밀히 체결함과 동시에 철근콘크리트 구조물 전반에 우수한 시공성과 경제성을 얻을 수 있는 철근연결구조를 제공코져 하는 것이다.The present invention has been made to solve the problems of the conventional reinforcing bar connection structure, forming an insertion hole having a diameter larger than the outer diameter of the reinforcing bar, the stopper is coupled to the center portion, the several fixed protrusions formed spike Provide a connector with a simple configuration combining the bolts respectively, insert the ends of the reinforcement to the stopper abutting on both sides of the insertion hole of the connector, and tighten the fixing bolts so that the spikes are dug into the outer circumferential surface of the reinforcement Therefore, to close the joint of the reinforcing bars and reinforcing bars and at the same time to provide a reinforcing bar connecting structure to obtain excellent construction and economical efficiency in the overall reinforced concrete structure.

철근(40)(41)의 외경보다 큰 직경의 삽입공(11)이 형성되고, 중앙부를 수직관통하는 스토퍼(20)가 결합되며,Insertion hole 11 having a diameter larger than the outer diameter of the reinforcing bar 40, 41 is formed, the stopper 20 is vertically penetrated through the center,
상기 스토퍼(20)를 경계로하여 좌, 우측에는 수개의 나사공(12)이 서로 수직방향으로 마주보며 뚫리고, 나사공(12)에는 일측 단면부로 끝이 뾰족한 스파이크(31)가 돌출형성된 고정볼트(30)를 각각 결합하여 철근 연결구(10)를 구성하며,Fixing bolts having a plurality of threaded holes 12 facing each other in the vertical direction on the left and right sides with the stopper 20 as a boundary, and a spike 31 having a pointed tip 31 at one end portion thereof protruding from the screwed hole 12. Combining each of the (30) constitutes a rebar connector 10,
상기 연결구(10)의 삽입공(11) 양측으로 철근(40)(41)의 끝부분이 각각 스토퍼(20)에 맞닿여 멈추도록 삽입하고,Inserted so that the ends of the reinforcing bars 40, 41 abut the stopper 20, respectively, to both sides of the insertion hole 11 of the connector 10,
연결구(10)의 나사공(12)에 각각 조립된 고정볼트(30)를 조임공구로 조여주면, 고정볼트(30) 단면부에 돌출형성된 스파이크(31)가 철근(40)(41)의 바깥둘레 표면을 파고든 후 멈추도록하므로서, 철근(40)과 철근(41)이 긴밀히 체결, 고정되도록 한 것을 특징으로 한다.When the fixing bolts 30 respectively assembled in the screw holes 12 of the connector 10 are tightened with the tightening tool, the spikes 31 protruding from the end surfaces of the fixing bolts 30 are formed outside the reinforcing bars 40 and 41. The rebar 40 and the reinforcing bar 41 are tightly fastened and fixed by stopping after digging the circumferential surface.
상기 본 고안의 철근연결구조에 따른 철근연결과정 및 작용을 살펴보면;Looking at the reinforcing bar connection process and action according to the reinforcing bar structure of the present invention;
먼저, 한쪽 철근(40)을 잡고 끝부분을 연결구(10)의 삽입공(11) 일측으로 밀어 넣는다.First, grab one of the reinforcing bar 40 and push the end portion into the insertion hole 11 side of the connector (10).
상기 삽입공(11)으로 진입한 철근(40)은 연결구(10)의 중앙부을 관통하여 결합된 스토퍼(20)에 맞닿이면서 진입을 멈추게 된다.The reinforcing bar 40 entering the insertion hole 11 is stopped by entering the stopper 20 coupled to penetrate through the central portion of the connector 10.
연결구(10)의 일측 삽입공(11)으로 철근(40)의 진입이 완료되면, 스토퍼(20)를 경계로하여 연결구(10)의 일측 바깥둘레에 서로 마주보며 뚫린 수개의나사공(12)에 각각 가조립된 고정볼트(30)를 스패너 또는 육각렌치 등의 조임공구로 조여준다.When the entry of the reinforcing bar 40 into one side insertion hole 11 of the connector 10 is completed, several screw holes 12 facing each other on the one outer circumference of the connector 10 with the stopper 20 as a boundary Tighten the fixing bolts 30 respectively assembled in the tightening tool such as a spanner or a hexagon wrench.
상기 고정볼트(30)는 육각머리볼트나 스크류볼트를 선택적으로 조립체결할 수 있는 것이며, 고정볼트(30)의 육각머리 타측 단면부 또는 렌치 삽입홈 타측 단면부에는 끝이 뾰족한 스파이크(31)가 돌출형성된다.The fixing bolt 30 can be assembled to the assembly of the hexagonal head bolt or screw bolt selectively, the other end of the hexagon head of the fixing bolt 30 or the other end of the wrench insertion groove spikes 31 having a sharp end Protruding.
상기 수개의 고정볼트(30)를 조임공구로 조여주게 되면, 고정볼트(30)는 철근(40)을 향해 수직방향으로 진행하여 바깥둘레 면에 맞닿이게 되는 바, 고경도의 특수강으로된 고정볼트(30)를 계속 조여주면 단면부에 돌출된 스파이크(31)가 철근(40)의 표면을 파고들면서 멈추게 됨으로서 연결구(10) 일측으로 삽입된 철근(40)의 끝부분을 긴밀히 체결고정하게 되는 것이다.When the several fixing bolts 30 are tightened with a tightening tool, the fixing bolts 30 proceed in the vertical direction toward the reinforcing bar 40 to be brought into contact with the outer circumferential surface. The fixing bolts are made of special steel of high hardness. If you continue to tighten (30) is to stop the spike 31 protruding in the cross section to the surface of the reinforcing bar 40 to stop tightly tighten the end of the reinforcing bar 40 inserted into one side of the connector (10). .
서로 마주보며 나사공(12)에 가조립된 수개의 고정볼트(30)를 조여줄 때는 철근(40)이 연결구(10) 내경의 중심축선상에 위치시킨 후, 마주보는 양측 고정볼트(30)를 교대로 각각 조여주는 것이 가장바람직하다.When fastening several fixing bolts 30 assembled to the threaded hole 12 facing each other, the reinforcing bar 40 is positioned on the central axis of the inner diameter of the connector 10, and then the opposite fixing bolts 30 are opposite to each other. It is most desirable to tighten each alternately.
상기와 같은 방법으로 한쪽 철근(40)의 고정이 완료된 후, 다른 한쪽 철근(41)을 연결구(10) 타측 삽입공(11)으로 밀어 넣게 되면, 철근(41)은 타측에 삽입고정된 철근(40)과 마찬가지로 스토퍼(20)에 맞닿이면서 진입을 멈추게 된다.After the fixing of one reinforcing bar 40 is completed in the same manner as described above, when the other reinforcing bar 41 is pushed into the other insertion hole 11 of the connector 10, the reinforcing bar 41 is inserted into and fixed to the other side ( As in 40, the entry is stopped while contacting the stopper 20.
상기 스토퍼(20)는 연결구(10)의 좌, 우측면을 기준으로 한가운데 나사결합된 것으로, 양측으로 각각 삽입되는 철근(40)(41)의 삽입부 길이가 정확하게 일치되도록하는 역할을 한다.The stopper 20 is screwed in the middle of the left and right sides of the connector 10, and serves to ensure that the lengths of the insertion portions of the reinforcing bars 40 and 41 respectively inserted into both sides are exactly matched.
한편, 철근(41)의 진입이 완료된 후, 스토퍼(20)를 경계로하여 연결구(10)의 타측 바깥둘레에 서로 마주보며 뚫린 수개의 나사공(12)에 각각 가조립된 고정볼트(30)를 상기와 마찬가지로 조임공구로 조여준다.On the other hand, after the entry of the reinforcing bar 41 is completed, the fixing bolt 30 respectively assembled in several screw holes 12 facing each other on the other outer circumference of the connector 10 with the stopper 20 as a boundary, respectively Tighten with a tightening tool as above.
상기 수개의 고정볼트(30)를 조임공구로 조여주게 되면, 고경도의 특수강으로 된 고정볼트(30)는 철근(41)의 바깥둘레 면에 맞닿이게 되고, 스파이크(31)가 철근(41)의 표면을 파고든 후 멈추게 됨으로서, 연결구(10) 일측으로 삽입된 철근(41)의 끝부분을 긴밀히 체결고정하게 되는 것이다.When the several fixing bolts 30 are tightened with a tightening tool, the fixing bolts 30 made of high hardness special steel are brought into contact with the outer circumferential surface of the reinforcing bar 41, and the spikes 31 are reinforced with the bar 41. By digging the surface of the stop and then, the end of the reinforcing bar 41 inserted into one side of the connector 10 will be tightly fastened.
상기 본 고안의 철근연결구조에 있어서, 연결구(10)의 삽입공(11) 직경을 철근(40)(41)의 외경보다 크게 형성한 것은 도 4와 같이 철근(40)(41)을 고정볼트(30)로서 체결한 후 콘크리트를 타설할 시 연결구(10) 내측으로 콘크리트가 유입, 굳어지게 함으로서 철근연결부위를 더욱 견고히 체결할 수 있도록 한 것이다.In the reinforcing bar structure of the present invention, the diameter of the insertion hole 11 of the connector 10 is larger than the outer diameter of the reinforcing bar 40, 41 is fixed to the reinforcing bar 40, 41 as shown in FIG. (30) After the concrete is poured into the connector 10 when the concrete is poured into the concrete, it will be able to tighten the reinforcing connection more firmly.
이상에서 상세히 살펴본 바와 같이 본 고안은 철근(40)(41)의 외경보다 큰 직경의 삽입공(11)을 형성하고, 중앙부에 스토퍼(20)를 결합하며, 단면부에 끝이 뾰족한 스파이크(31)가 돌출형성된 수개의 고정볼트(30)를 서로 수직방향으로 마주보도록 각각 결합하여 철근 연결구(10)를 구성한 후,As described in detail above, the present invention forms an insertion hole 11 having a diameter larger than the outer diameter of the reinforcing bars 40 and 41, couples the stopper 20 to the center, and has a sharp pointed end portion 31. After combining the fixing bolts (30) protruding from each other to face each other in the vertical direction to form a reinforcing connector (10),
상기 연결구(10)의 삽입공(11) 양측으로 철근(40)(41)의 끝부분이 각각 스토퍼(20)에 맞닿여 멈추도록 삽입하고, 연결구(10)의 나사공(12)에 각각 조립된 고정볼트(30)를 조임공구로 조여주면, 고정볼트(30) 단면부에 돌출형성된 스파이크(31)가 철근(40)(41)의 바깥둘레 표면을 파고든 후 멈추게 되어, 철근(40)과 철근(41)이 긴밀히 체결, 고정되도록 하므로서,Insert the end portions of the reinforcing rods 40 and 41 to both sides of the insertion hole 11 of the connector 10 so as to contact and stop the stopper 20, respectively, and assembled to the screw holes 12 of the connector 10, respectively. When the fixed bolt 30 is tightened with a tightening tool, the spike 31 protruding from the end of the fixed bolt 30 cuts into the outer circumferential surface of the reinforcing bars 40 and 41, and then stops. As the rebar 41 is tightly fastened and fixed,
종래의 겹이음, 용접이음 방식에서 발생할 수 있는 부실공사, 수명감축 및 철근의 막대한 손실을 방지하고, 기계식 나사이음 보다 간단한 구성부재를 사용하여 철근 연결작업을 간단히 수행할 수 있게 되어, 각종 건물이나 교량 및 터널, 댐, 고속도로 등 철근콘크리트 구조물 전반에 우수한 시공성과 경제성을 제공할 수 있게 되는 등 그 기대되는 가치가 다대한 매우 유용한 고안이다.It prevents inadequate construction, lifespan reduction and remarkable loss of reinforcing bars, which can occur in conventional lap joints and welding joints, and it is possible to easily perform reinforcing bar connections using components that are simpler than mechanical screw joints. It is a very useful design with great expected value, such as being able to provide excellent construction and economic feasibility over reinforced concrete structures such as bridges, tunnels, dams and highways.
