Description
본 고안은 철근 콘크리트 구조물의 골조로 사용되는 철근을 상호 연결시키는 철근 연결장치에 관한 것이다.The present invention relates to a reinforcing bar connecting device for interconnecting the reinforcing bar used as a frame of the reinforced concrete structure.
일반적으로 건축이나 토목공사에서 콘크리트 구조물의 강성보강을 위해 사용되는 철근은 소정의 길이를 갖도록 절단된 상태로 공사 현장에 공급된다. 그리고 콘크리트 타설작업에 앞서 철근을 시공할 때에는 상호 결속이 요구되는 두 철근의 단부를 겹친 상태에서 가는 철선 등으로 결박하는 방식을 취하여 구조물의 골격이 형성되도록 한다.In general, reinforcing bars used for stiffness reinforcement of concrete structures in construction or civil engineering are supplied to the construction site in a state of being cut to have a predetermined length. And before reinforcing the concrete, when constructing the reinforcing bars, the structure of the structure is formed by binding the ends of the two reinforcing bars which are required to be bonded together with thin wires.
그러나 이러한 종래의 철근 연결방식은 연결할 두 철근의 단부를 중첩시킨 상태에서 철선으로 결박하기 때문에, 철근이 상호 겹치는 부분으로 인해 재료의 손실이 큰 문제가 있을 뿐만 아니라, 철선을 수 차례 감아서 조여주어야 하는 등 결속작업이 더디기 때문에 작업성이 떨어져 공기지연을 야기하는 문제가 있었다.However, such a conventional reinforcing bar connection method is because the binding of the steel bars in the overlapping state of the reinforcing bars, there is a big problem of material loss due to the overlapping parts of the rebar, as well as winding the wire several times There is a problem that causes air delay because workability is poor because the binding work is slow.
또한 종래의 철근 연결방식은 콘크리트 층 내에 매입된 후에 철근을 결속하는 철선이 쉽게 산화하여 결속상태가 해지되기 때문에, 철근 길이방향으로의 압축력이나 인장력이 취약하여 구조물 붕괴의 원인이 되는 문제가 있었다.In addition, in the conventional reinforcing bar connection method, since the steel wire to bind the reinforcing bar is easily oxidized after the buried in the concrete layer, the binding state is terminated, there is a problem that causes the collapse of the structure due to the weak compressive force or tensile force in the longitudinal direction of the rebar.
본 고안은 이와 같은 문제점들을 해결하기 위한 것으로, 본 고안의 목적은 철근의 연결부가 맞대기 이음으로 결속되도록 함으로써 재료의 절감을 꾀할 뿐만 아니라, 연결부의 충분한 강성을 유지할 수 있으며, 결속작업 또한 용이하여 공사기간을 크게 단축할 수 있는 철근 연결장치를 제공하는 것이다.The present invention is to solve such problems, the object of the present invention is to reduce the material by binding the connection of the reinforcing bar butt joint, it is possible to maintain a sufficient rigidity of the connection, and also easy to bind work It is to provide a reinforcing bar connection device that can greatly shorten the period.
본 고안의 다른 목적은 철근을 연결하는 연결수단의 산화가 방지되도록 함으로써 연결부가 콘크리트 층 내에 매입된 후에도 강한 결속상태를 유지하여 구조물의 강성이 향상되도록 하는 철근 연결장치를 제공하는 것이다.Another object of the present invention is to provide a reinforcing bar connection device to prevent the oxidation of the connecting means for connecting the reinforcing bars to maintain a strong binding state even after the connection is embedded in the concrete layer to improve the rigidity of the structure.

본 고안에 따른 철근 연결장치는 도 1과 도 2에 도시된 바와 같이, 결속이 요구되는 두 철근(1,2)의 양단이 내부로 끼워질 수 있도록 중공의 원통형상으로 마련된 결속부재(10)와, 이 결속부재(10)의 외면에 끼워져서 결속부재(10)를 조여줄 수 있도록 링형상으로 마련된 한 쌍의 조임부재(20)를 포함한다.Reinforcing bar connecting device according to the present invention is shown in Figure 1 and 2, the binding member 10 is provided in a hollow cylindrical shape so that both ends of the two reinforcing bars (1,2) to be bound to be fitted into the interior And a pair of fastening members 20 provided in a ring shape so as to fit on the outer surface of the fastening member 10 and tighten the fastening member 10.
결속부재(10)는 내부로 진입되는 두 철근(1,2)의 외면을 조여줄 수 있도록 양측의 내경이 신축 가능하도록 마련된다. 이를 위해 결속부재(10)의 외면에는 양단부로부터 길이방향으로 절개되어 형성된 다수의 절개홈(11)이 마련된다. 이때 결속부재(10)의 중앙부분에는 강성의 유지를 위해 절개홈(11)이 형성되지 않는다. 또 결속부재(10)의 내측 중앙에는 도 3에 도시된 바와 같이, 결속부재(10)의 중앙부 강성을 보강하는 한편 양측으로부터 끼워지는 철근(1,2)의 진입을 제한하는 진입제한턱(14)이 형성된다. 즉 결속부재(10)는 이 진입제한턱(14)을 기준으로 양측이 대칭을 이룬다.The binding member 10 is provided to allow the inner diameters of both sides to be stretchable to tighten the outer surfaces of the two reinforcing bars 1 and 2 that enter the inside. To this end, the outer surface of the binding member 10 is provided with a plurality of cutting grooves 11 formed by cutting in the longitudinal direction from both ends. At this time, the center portion of the binding member 10 is not formed in the cutting groove 11 for maintaining the rigidity. In addition, at the inner center of the binding member 10, as shown in FIG. 3, the entry limiting jaw 14 which reinforces the central part rigidity of the binding member 10 and restricts the entry of the reinforcing bars 1 and 2 fitted from both sides. ) Is formed. That is, the binding member 10 is symmetrical on both sides with respect to the entry limit (14).
또한 결속부재(10)는 외면에 끼워지는 두 조임링(20)이 양단부 쪽으로 당겨질 때 양단의 내경이 조여질 수 있도록 외면이 소정의 경사(θ)를 이루어 양단부 쪽으로 갈수록 그 두께(t)가 점차 두꺼워지도록 구성된다. 그리고 결속부재(10)의 외면에 끼워지는 두 조임부재(20)의 내면도 결속부재(10)의 외면 경사(θ)에 대응하는 경사를 이루도록 형성된다.In addition, the binding member 10 has a predetermined inclination (θ) so that the inner diameter of both ends can be tightened when the two tightening rings 20 fitted on the outer surface are pulled toward both ends, and the thickness t gradually increases toward both ends. It is configured to be thick. In addition, the inner surfaces of the two fastening members 20 fitted to the outer surface of the binding member 10 are also formed to have an inclination corresponding to the outer surface inclination θ of the binding member 10.
또한 결속부재(10)의 외면과 조임부재(20)의 내면에는 철근(1,2)을 결속할 때 조임부재(20)의 역류를 방지하기 위한 다수의 역류방지턱(12,22)이 돌출 형성된다. 이 역류방지턱(11,22)은 결속부재(10)의 외면과 조임부재(20)의 내면에 산형으로 돌출하는데, 결속부재(10)의 외면에는 도 3에 도시된 바와 같이, 중앙부 쪽에 위치하는 경사면(12a)과, 결속부재(10)의 양단부 쪽에 위치하는 수직면(12b)이 반복 형성된 구조로 이루어지며, 조임부재(20)의 내면은 결속부재(10) 외면의 역류방지턱(12)에 대향하여 걸리는 반대의 구조로 형성된다. 이러한 구성은 결속부재(10)의 외면에 끼워진 두 조임부재(20)가 결속부재(10)의 양단부 쪽으로 당겨졌을 때, 역류방지턱(12,22)을 통해 걸려 역방향으로 후퇴하지 않도록 함으로써 철근(1,2)의 조임상태가 유지되도록 한 것이다.In addition, on the outer surface of the binding member 10 and the inner surface of the fastening member 20, a plurality of backflow prevention projections 12 and 22 for preventing the back flow of the fastening member 20 when binding the reinforcing bars 1 and 2 are formed. do. The non-return jaw (11, 22) protrudes in the form of a mountain on the outer surface of the binding member 10 and the inner surface of the fastening member 20, the outer surface of the binding member 10, as shown in FIG. The inclined surface 12a and the vertical surface 12b positioned at both ends of the binding member 10 are formed repeatedly, and the inner surface of the tightening member 20 is opposed to the backflow prevention jaw 12 on the outer surface of the binding member 10. It is formed into the opposite structure that is hung toward This configuration is such that when the two fastening members 20 fitted on the outer surface of the binding member 10 are pulled toward both ends of the binding member 10, they are caught by the backflow prevention jaws 12 and 22 so as not to retreat in the reverse direction. 2) is to maintain the tightening state.
또한 결속부재(10)의 내면에는 철근(1,2)과 결속부재(10)의 결합이 더욱 강화될 수 있도록 다수의 돌기(13)가 형성된다. 이는 조임부재(20)를 통해 결속부재(10)의 양단이 조여질 때 내면의 돌기(13)가 철근(1,2)의 외면에 형성된 턱(1a,2a)과 걸림구조를 이룸으로써 더욱 강한 결속이 이루어지도록 한 것이다.In addition, a plurality of protrusions 13 are formed on the inner surface of the binding member 10 to further strengthen the coupling of the reinforcing bars 1 and 2 and the binding member 10. This is stronger when both ends of the binding member 10 is tightened through the fastening member 20, so that the protrusion 13 on the inner surface forms a locking structure with the jaws 1a and 2a formed on the outer surface of the reinforcing bars 1 and 2. Unity is made.
그리고 이러한 결속부재(10)는 절개홈(11)이 형성된 양단이 소정의 탄성을 구비하여 철근(1,2)을 끼우기 용이하도록 하는 것이 좋으며, 그 재질이 소정의 강성을 지닌 플라스틱 사출물로 제작됨으로써, 제작이 용이하도록 함과 동시에 철근(1,2)의 결속 후 콘크리트 층에 매입이 되더라도 그 강성이 반영구적으로 유지되도록 하는 것이 좋다.And the binding member 10 is preferably both ends formed with the cutting groove 11 has a predetermined elasticity to facilitate the reinforcement (1, 2), the material is made of a plastic injection molding having a predetermined rigidity In addition, it is good to make it easy to manufacture and to maintain the stiffness semi-permanently even if it is embedded in the concrete layer after the binding of the reinforcing bars (1,2).
이와 같이 구성된 철근 연결장치의 결속동작을 설명하면 다음과 같다.Referring to the binding operation of the reinforcing bar connection device configured as described above are as follows.
철근(1,2)을 결속하기에 앞서 결속부재(10)의 외면에는 먼저 한 쌍의 조임부재(20)가 끼워지는데, 결속부재(10)의 양단이 절개된 상태이므로 조임부재(20)의 결합은 용이하게 이루어진다. 그리고 실제 건설현장에는 조임부재(20)가 결속부재(10)에 결합된 상태로 공급된다.Prior to binding the reinforcing bars (1, 2), a pair of fastening members 20 are first fitted to the outer surface of the binding member 10, since both ends of the binding member 10 are cut out of the fastening member 20 The coupling is easy. And the actual construction site is supplied with a fastening member 20 coupled to the binding member 10.
이러한 철근 연결장치로 철근을 결속할 때는 도 3에 도시된 바와 같이, 결속부재(10)의 내부로 두 철근(1,2)의 양단을 진입시킨 후, 결속부재(10) 외면에 결합된 두 조임부재(20)를 결속부재(10)의 양단 쪽으로 당겨주기만 하면 모든 결합이 완료된다. 즉 결속부재(10)는 외면이 경사(θ)를 이루어 양측으로 갈수록 두께(t)가 두꺼워지기 때문에 두 조임부재(20)를 양측으로 당길 때 결속부재(10)의 내경이 작아지면서 철근(1,2)의 외면을 조여준다. 또한 이때 결속부재(10) 내면의 돌기(13)가 철근(1,2) 외면의 턱(1a,2a)과 결속되어 더욱 견고한 결합상태를 이룬다.When binding the reinforcing bar with such a reinforcing bar connection device, as shown in Figure 3, after entering both ends of the two reinforcing bars (1, 2) into the binding member 10, the two coupled to the outer surface of the binding member (10) All the coupling is completed just by pulling the fastening member 20 toward both ends of the binding member 10. In other words, the binding member 10 is inclined (θ) on the outer surface, the thickness (t) becomes thicker toward both sides, so the inner diameter of the binding member 10 becomes smaller when the two fastening members 20 are pulled to both sides. Tighten the outer surface of, 2). In addition, the protrusion 13 on the inner surface of the binding member 10 is engaged with the jaws 1a and 2a on the outer surfaces of the reinforcing bars 1 and 2 to achieve a more firm coupling state.
또한 결속부재(10)의 양단은 절개홈(11)을 통해 절개되어 있기 때문에 철근(1,2)을 용이하게 끼울 수 있게 되며, 두 조임부재(20)는 역류방지턱(12,22)을 통해 후퇴하지 않기 때문에 견고한 결속상태가 유지된다.In addition, since both ends of the binding member 10 are cut through the cutting groove 11, the reinforcing bars 1 and 2 can be easily fitted, and the two fastening members 20 are provided through the backflow prevention jaws 12 and 22. Since it does not retreat, a solid binding state is maintained.
그리고 도 4에 도시된 바와 같이, 이러한 연결장치가 콘크리트 층 내부에 매입된 상태에서는 햇빛과 같은 외부의 요인에 노출되지 않게 되므로, 플라스틱 사출물의 특성상 산화와 부식이 방지되어 최초의 결속상태가 반영구적으로 유지되기 때문에 구조물의 강성을 더욱 높여준다.As shown in FIG. 4, since the connection device is embedded in the concrete layer, the connection device is not exposed to external factors such as sunlight, so that oxidation and corrosion are prevented due to the characteristics of the plastic injection molding, and thus the first binding state is semipermanently. Maintains the structure more rigidly.
이상에서 상세히 설명한 바와 같이, 본 고안에 따른 철근 연결장치는 결속부재에 끼워지는 두 철근이 맞대기 이음으로 결속되기 때문에 연결부의 중첩이 방지되어 재료를 절감할 수 있는 효과가 있다.As described in detail above, the reinforcing bar connecting device according to the present invention is because the two reinforcing bars fitted to the binding member is bound by the butt joint, there is an effect that can prevent the overlap of the connection to reduce the material.
또한 본 고안은 철근을 결속할 때 두 철근을 결속부재에 끼운 상태에서 조임부재만 양측으로 당겨주면 견고한 결속이 이루어지기 때문에, 연결부의 강성이 우수할 뿐만 아니라 결속작업이 용이하여 골조공사 기간을 크게 단축할 수 있는 효과가 있다.In addition, the present invention, when binding the reinforcing bar when the two reinforcing bar is inserted in the binding member by pulling only the fastening member to both sides, because the solid binding is made, not only the rigidity of the connection is easy but also the binding work is easy to greatly increase the frame construction period There is an effect that can be shortened.
또한 본 고안은 철근을 결속하는 결속부재가 플라스틱 사출물로 이루어지기 때문에 산화와 부식이 방지되어 콘크리트 층 내에 매입된 후에도 강한 결속상태를 유지하게 됨으로써 콘크리트 구조물의 강성을 향상시키는 효과가 있다.In addition, the present invention has the effect of improving the rigidity of the concrete structure because the binding member for binding the reinforcing bar is made of a plastic injection molding to prevent oxidation and corrosion to maintain a strong binding state even after being embedded in the concrete layer.
