본 고안은 연결되는 철근의 이음부를 효율적으로 연결하여 주는 철근이음용 슬리브에 관한 것이다.The present invention relates to a sleeve for reinforcing bar connecting the joint of the reinforcing bar efficiently.
일반적으로 철근을 사용하여 건축물 또는 구조물을 시공할때 철근과 철근이 소정의 길이만큼 상호 겹쳐져서 철사로 감싸매어서 연결되는 이음부를 가지게 된다. 이러한 이음부는 외력에 대한 저항력에 대응하기 위해 충분한 이음길이를 가져야 할 필요가 있는데, 건축물의 구조 기준 등에 의하면 철근의 이음길이는 압축근 또는 작은 인장력을 받는 곳은 주근(主筋) 지름의 25배 이상, 큰 인장력을 받는 곳은 주근지름의 40배 이상으로 해야 한다고 규정하고 있다. 이와 같이 두 철근의 연결시 주근지름의 25배이상 또는 40배이상으로 겹쳐지도록 하기 위해서는 반드시 철근의 여유분이 필요하게 된다.In general, when constructing a building or a structure using reinforcing bars, the reinforcing bars and reinforcing bars overlap each other by a predetermined length and have joints connected by being wrapped with wires. These joints need to have sufficient joint lengths to cope with the resistance to external forces. According to the structural standards, the joint length of the reinforcing bar is more than 25 times the main bar diameter in the place where the compression bar or small tensile force is applied. In other words, it is required that the places subject to high tensile strength should be at least 40 times the main diameter. As such, when the two reinforcing bars are connected to each other at least 25 times or 40 times larger than the main bar diameter, the reinforcing bar is necessarily required.
이와 같은 종래의 철근이음은 연결되는 철근들이 겹쳐져서 연결되므로 철근의 소요량이 증대되었을 뿐만 아니라, 그 겹쳐진 부분을 철사로 감싸매서 묶어야 하기 때문에 인력과 작업시간이 낭비되는 결점이 있었다. 뿐만 아니라 그 겹쳐진 부분을 철사로 감싸매서 묶어야 하기 때문에 철사의 낭비도 있었다.Such a conventional reinforcing bar joint is connected to the overlapping reinforcing bars are not only increased the requirements of the reinforcing bars, but also because of the need to wrap and tie the overlapped portion of the wire was a defect that wastes manpower and work time. In addition, there was a waste of wire because it had to be wrapped in wire and tied up.
또한, 현장시공상 철근연결작업시 이음길이를 충분히 확보하지 못할 뿐만 아니라, 이음길이가 전혀없이 철근의 말단면과 말단면을 맞대어서 콘크리트를 타설하는 경우가 부득불 발생한다. 이와 같이 이음길이를 충분히 확보하지 못하거나, 이음길이가 전혀없이 철근의 말단면과 말단면을 맞대어서 콘크리트로 타설시공되는 구조물은 외력에 대한 저항력이 약할 뿐만 아니라, 힘이 효율적으로 전달되지 못하기 때문에 구조적으로 불안정한 구조물이 되고 만다. 따라서 철근와 연결작업시 부득불 이음길이를 충분히 확보하지 못하거나 이음길이가 전혀없이 철근연결작업을 해주어야 할 필요가 있다.In addition, not only does not secure enough joint length when connecting the reinforcing works in the field construction, but inevitably occurs when the concrete is placed to the end face and end face of the reinforcing bar without any joint length. As such, the structures that are not sufficiently secured or have no joint length at all, but are placed in concrete by facing the end and end surfaces of the reinforcing bars, are not only weak in external forces but also incapable of transmitting power efficiently. As a result, it becomes a structurally unstable structure. Therefore, it is necessary to perform reinforcing bar connection work without sufficient unsecured joint length or no joint length at all.
본 고안의 목적은 철근의 연결작업시 철근의 겹쳐지는 부분이 전혀없이 연결되도록 하여 외력에 대한 저항력에 충분히 대응하여 주면서도 힘이 효율적으로 전달되는 철근이음용 슬리브를 제공하여 주는데 있다.An object of the present invention is to provide a reinforcing bar sleeve for the force is efficiently transmitted while fully responding to the resistance to external forces by connecting the overlapping portion of the reinforcing bar at all when connecting the rebar.
이하, 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.
본 고안의 철근이음용 슬리브(1)는 제1도에서 도시되는 바와 같이, 전체적으로 반원통형을 가지되 우측으로는 외측으로 직각절곡되며 나사구멍(111)들이 뚫려지는 우측연장부(110)가 연장도고 좌측으로는 접선상으로 길게 연장되며 끼움구멍(121)들이 뚫려지는 좌측연장부(120)가 연장되는 몸체부(100)와, 상기 좌측연장부의 끼움구멍(121)들에 끼움부(220)가 끼워지고 우측연장부위로 조임고정부(210)가 연장되어 덮여지는 덮개판(200)들과, 상기 덮개판들의 조임고정부(210)를 우측연장부의 나사구멍(111)들에 나사결합하여 고정시켜 주는 조임볼트(300)들로 구성됨을 특징으로 한다.As shown in FIG. 1, the sleeve 1 for a reinforcing bar of the present invention has a semi-cylindrical shape as a whole, but is bent at right angles to the outside and the right extension part 110 in which the screw holes 111 are drilled extends. The body portion 100 is extended to the left side and extends tangentially to the left side and the left extension 120 through which the fitting holes 121 are opened, and the fitting portion 220 at the fitting holes 121 of the left extension portion. Is fitted and the cover plates 200 are covered with the tightening fixing portion 210 is extended to the right extension portion, and the tightening fixing portions 210 of the cover plates are screwed into the screw holes 111 of the right extending portion. Characterized by consisting of the fastening bolts 300 for fixing.
이와 같이 구성되는 본 고안은 몸체부(100)의 좌측연장부(120)의 끼움구멍(121)들에 각각 덮개판(200)의 끼움부(220)가 끼워지고 몸체부(100)의 우측연장부(110)의 나사구멍(111)들에 각각 덮개판(200)의 조임고정부(210)가 일치되도록 하여 조임볼트(300)들로 조일 수 있도록 한 것이며, 철근연결작업시는 조여진 조임볼트(300)를 어느정도 느슨하게 푼다음 몸체부(100)의 내면과 덮개판(200)의 내면사이로 형성된 공간의 일측과 타측으로 연결할 철근들의 이음부들을 각각 삽입하고 다시 조임볼트(300)를 조이면 철근의 이음부가 몸체부(100)의 내면과 덮개판(200)의 내면 사이에서 압착되어 콘크리트에 매립연결 사용되는 것이다.According to the present invention configured as described above, the fitting portions 220 of the cover plate 200 are fitted into the fitting holes 121 of the left extending portion 120 of the body portion 100, and the right extending of the body portion 100 is provided. The fastening fixing parts 210 of the cover plate 200 are respectively matched to the screw holes 111 of the part 110 to be fastened with the fastening bolts 300, and the tightening fastening bolts at the time of rebar connection work. Loosen the 300 to some extent and then insert the joints of the reinforcing bars to be connected to one side and the other side of the space formed between the inner surface of the body portion 100 and the inner surface of the cover plate 200 and tighten the tightening bolts 300 again. The joint is pressed between the inner surface of the body portion 100 and the inner surface of the cover plate 200 is used to be embedded in the concrete.
상기 몸체부(100)는 필요한 길이 만큼 절단하여 사용할 수 있다. 즉 힘의 전달이 큰 곳에서는 몸체부를 길게하여 사용하는 것이 좋으며 힘의 전달이 작은 곳에서는 몸체부를 짧게 하여 사용하는 것이 좋다. 몸체부가 반원통형을 가지도록하는 것은 단면상 둥근모양의 철근이 몸체부(100)에 삽입되었을때 일부가 몸체부로부터 돌출되도록 하여 덮개판(200)에 의해서 압착되도록 하기 위함이다. 이때 조임볼트(300)를 조여주면 덮개판(200)에 의해서 삽입된 철근(2)이 압착된다.The body portion 100 can be used by cutting to the required length. That is, it is good to use the body part long in the place where the force transmission is large, and use the body part short in the place where the force transmission is small. The body portion is to have a semi-cylindrical shape is to be pressed by the cover plate 200 so that a portion of the round reinforcement in the cross-section is inserted into the body portion 100 to protrude from the body portion. At this time, when tightening the tightening bolt 300, the reinforcement (2) inserted by the cover plate 200 is compressed.
또한 몸체부(100)의 우측으로는 외측으로 직각절곡되는 우측연장부(110)에 나사결합할 수 있는 나사구멍(111)들이 뚫려지며, 나사구멍(111)의 하면에 제1도에서 도시되는 바와 같이, 고정너트(112)가 용접되어서 조임볼트(300)의 결합시 부착력을 증대하여 주는 효과를 가진다.In addition, the right side of the body portion 100 is a screw hole 111 that can be screwed to the right extension portion 110 is bent at an angle to the outside is drilled, as shown in Figure 1 on the lower surface of the screw hole 111 As such, the fixing nut 112 is welded to have an effect of increasing the adhesive force when the tightening bolt 300 is coupled.
또한, 제1도에서 도시되는 바와 같이, 몸체부(100)의 중간지점에 이음부확인구멍(130)이 뚫려지도록 하는 것이 바람직하다. 이는 몸체부(100)의 일측과 타측에 각각 삽입되는 두개의 연결되는 철근이 정확히 중심부에 삽입되었는지 확인할 수 있기 위함이다.In addition, as shown in Figure 1, it is preferable to make the joint confirmation hole 130 in the intermediate point of the body portion 100. This is to confirm whether the two connected reinforcing bars respectively inserted into one side and the other side of the body portion 100 are correctly inserted in the center.
한편, 몸체부(100)의 내면에 요홈 또는 돌기들을 형성할 수도 있음을 밝혀둔다. 이는 몸체부(100) 내부에 모르타르가 충진될때 몸체부(100)의 내면과 모르타르와의 부착강도를 증대하여 주기 때문에 결국 연결되는 철근들의 부착강도를 증대시켜 주는 효과를 가진다. 또한 몸체부(100)의 양단부들을 오므라지게 하여 부착강도를 증대할 수 있음도 밝혀둔다.On the other hand, it should be noted that grooves or protrusions may be formed on the inner surface of the body portion 100. This increases the adhesion strength between the inner surface of the body portion 100 and the mortar when the mortar is filled in the body portion 100 has the effect of increasing the adhesion strength of the reinforcing bars are eventually connected. In addition, it is also revealed that by attaching both ends of the body portion 100 can increase the attachment strength.
상기 덮개판(200)은 끼움구멍(121)들에 끼워지는 끼움부(220)와 우측연장부(110)위로 연장되는 조임고정부(210)로 구성되는 구조부로써 제2도 및 제3도에서 도시되는 바와 같이, 덮개판(200)들 중 중간에 위치하는 중간덮개판(200a)은 그 가운데 이음부확인구멍(230)이 장방형으로 길게 뚫려지도록 하는 것이 바람직하다. 이는 몸체부(100)의 중간지점에 뚫려진 이음부확인구멍(130)과 마찬가지로 몸체부(100)의 일측과 타측에 각각 삽입되는 두개의 연결되는 철근이 정확히 중심부에 삽입되었는지 확인할 수 있기 위함이다. 삽입되는 두개의 연결되는 철근이 정확히 중심부에 삽입되는 것은 구조적으로 매우 중요한데, 이는 힘이 연결되는 두 철근에 골고루 전달되도록 해야만 안정된 구조물이 되기 때문이다.The cover plate 200 is a structural portion consisting of a fastening portion 210 extending over the right portion 110 and the fitting portion 220 to be fitted to the fitting holes 121 in FIGS. 2 and 3 As shown, the middle cover plate (200a) located in the middle of the cover plate 200 is preferably such that the seam check hole 230 is a long rectangular opening therein. This is to confirm whether the two reinforcing bars respectively inserted in one side and the other side of the body portion 100 are inserted in the center, similarly to the joint confirmation hole 130 drilled in the middle of the body portion 100. . It is structurally very important that the two connecting reinforcing bars are inserted exactly in the center, because the force must be evenly transmitted to the two connecting bars to form a stable structure.
또한, 덮개판(200)들의 중간부가 제1도에서 도시되는 바와 같이, 상부로 만곡되며, 끼움부(220)도 상부로 절곡된 것을 예시해 보여준다. 중간부가 상부로 만곡되는 것은 삽입된 철근과의 마찰되는 면적을 넓게 하여 부착강도를 증대하는 효과를 가지고, 끼움부(220)가 상부로 절곡된 것은 끼움부가 좌측연장부의 외면에 걸리도록하여 탈리를 방지하는 효과를 가진다.In addition, the middle portion of the cover plate 200, as shown in FIG. 1, is bent upward, the fitting portion 220 also shows an example that is bent upwards. If the middle portion is curved upward, the friction area with the inserted reinforcing bar has an effect of increasing adhesion strength, and the fitting portion 220 is bent upwardly so that the fitting portion is caught on the outer surface of the left extension part so that it is detached. Has the effect of preventing.
상기 조임볼트(300)는 몸체부(100)의 나사구멍(111)과 덮개판(200)의 조임고정부(210)에 나사돌림으로 결합되어 몸체부(100)와 덮개판(200)을 결합하는 결합수단이다. 제1도에서 도시되는 바와 같이, 조임볼트로 체결하여 주는 것을 에시해 보여준다.The tightening bolt 300 is coupled to the screw hole 111 of the body portion 100 and the tightening fixing portion 210 of the cover plate 200 by screwing to couple the body portion 100 and the cover plate 200. It is a coupling means. As shown in Figure 1, it shows that the fastening with the tightening bolt.
이와 같이 본 고안은 철근들이 반드시 겹쳐져서 연결되므로 철근과 인력과 작업시간과 철사들이 낭비되었을 뿐만 아니라 부득불 이음길이를 충분히 확보하지 못하였거나 이음길이가 전혀없이 철근이음작업을 진핼할 경우 구조적으로 불안정한 구조물이 되었던 종래와는 달리, 전체적으로 반원통형을 가지는 몸체부의 좌측연장부의 끼움구멍들에 덮개판의 끼움부들이 끼워지고 몸체부의 우측연장부위로 덮개판의 조임고정부가 연장되도록 한 후, 몸체부내에 연결되는 두 철근의 말단면들이 서로 맞닿도록 삽입하고 조임볼트로 조여주므로 연결되는 두 철근이 몸체부와 덮개판사이에서 압착되면서 견고히 이러지게 되어 철근의 겹쳐지는 부분이 전혀없이 연결되며 외력에 대한 저항력에 충분히 대응하여 줄수 있는 작용효과를 가진다.Thus, the present invention is because the reinforcing bars are necessarily overlapped and connected, not only was the rebar, manpower, work time and wires was wasted, but the structure was unstable if the reinforcement was not secured enough or if the reinforcing bar was performed without any joint length at all. Unlike the conventional art, the fitting plate of the cover plate is fitted into the fitting holes of the left extension of the body part having a semi-cylindrical shape as a whole, and the tightening fixing part of the cover plate is extended to the right extension of the body part, and then connected to the body part. The end faces of the two reinforcing bars are inserted to be in contact with each other and tightened with a fastening bolt, so that the two connecting bars are pressed together between the body part and the cover plate so that they are firmly connected, so that the overlapping parts of the reinforcing bars are connected at all and are sufficiently resistant to external force. It has a corresponding effect.
또한 덮개판들 중 중간에 위치하는 덮개판은 그 가운데 이음부확인홈이 뚫려져서 연결되는 두 철근이 정확히 중간에 삽입시킬 수 있도록 하여 힘이 연결되는 두 철근에 골고루 전달되도록 하기 때문에 안정된 구조물을 건축할 수 있는 작용효과를 가진다.In addition, the cover plate located in the middle of the cover plate has a stable structure because it allows the two reinforcing bars to be inserted in the middle so that the connecting bars can be inserted in the middle. It has an effect that can be done.
이상에서 살펴 본 바와 같이 본 고안은 몸체부와 덮개판 사이에 연결되는 두 철근의 말단면들이 서로 맞닿도록 삽입하고 조임볼트로 조여주므로 연결되는 두 철근이 몸체부와 덮개판 사이에서 압착되면서 견고히 연결되어 외력에 대한 저항력에 충분히 대응하여 줄수 있는 매우 유용한 것이다.As described above, the present invention inserts the end faces of the two rebars connected between the body part and the cover plate to be in contact with each other and tightens them with a fastening bolt, so that the two reinforcing bars connected between the body part and the cover plate are pressed firmly. It is very useful to give enough resistance to external force.
