본 고안은 콘크리트 기둥에 내재하는 철근을 잇는 철근 연결구에 관한 것이다. 각종 건축물의 기둥은 건축물의 하중을 견뎌야할만큼의 압축강도를 가져야 하며 이러한 압축강도를 유지시키기 위하여 콘크리트 기둥내부에 철근을 내재시켜 왔던바 철근의 길이는 무한히 긴것이 아니므로 높은 기둥을 세우려면 다수개의 철근을 잇지 않으면 안되는 것이다.The present invention relates to a reinforcing bar connector connecting reinforcing bars inherent in a concrete column. The pillars of various buildings must have the compressive strength to withstand the load of the building. In order to maintain the compressive strength, the reinforcing bars have been embedded in the concrete columns. The length of the reinforcing bars is not infinitely long. You must connect the bars of the dog.

이와같이 철근을 이음에 있어서 종래에는 잇는 두개의 철근을 약 1m쯤 겹치게하고 겹쳐진 철근을 불에 달구어 식힌 철사로 묶어 연결시켰으나 이와같이 연결하게 되면 철근의 압축 강도가 현저히 저하되는 중대한 결점이 있고 이는 곧 건축물의 붕괴를 야기할 수 있는 중대한 문제를 가지게 된다. 뿐만아니라 이러한 종래의 방법은 철근이 약 1m쯤 겹쳐지므로 결국 자원의 낭비를 초래하고 철사로 묶어 연결시키는 작업이 용이치 아니하여 인건비의 부담을 가중시키는 결점이 있었다. 그리하여 연결되는 두개의 철근을 융접시키므로서 철근의 연결을 견고히 하는 기술이 개발되었던 것이다. 이와같이 철근을 용접시키는 것은 비용이 과다하여 그 이용이 활발치 못한 결점이 있었으며 철근이 완전 용접될때까지 연결되는 윗부분의 철근을 고정시키기 또한 곤란한 결점이 있었던 것이다. 이후 두개의 철근을 일측이 개구된 Ω형 압지통체와 압지통체의 개구부를 오무리는 조임쇠로 구성된 철근연결구가 안출되었다. (일본국 공개실용신안공고 50-86018)Thus, when connecting reinforcing bars conventionally, two connecting reinforcing bars overlap about 1m and the overlapping reinforcing bars are bundled with a cold wire and connected together. There is a serious problem that can cause collapse. In addition, this conventional method has a drawback of increasing the burden of labor costs because the reinforcing bars overlap about 1m, eventually causing a waste of resources and difficult to tie the wire connection. Thus, the technology of strengthening the connection of reinforcing bars was developed by fusion welding two reinforcing bars. Welding the reinforcing bar was excessively expensive and there was a drawback that it was not used actively, and it was also difficult to fix the reinforcing bar at the upper part until the rebar was fully welded. Afterwards, a reinforcing bar connector consisting of a wedge-shaped tack cylinder having one side of two rebars and a fastener closing the opening of the tack cylinder was devised. (Japanese Utility Model Notification 50-86018)

이와같은 연결구는 비교적 시공이 간편하고 염가이어서 바람직 하기는 하나 조임쇠의 상단을 망치로 때려 압지통체를 조일때 조임쇠의 상단이 철근에 근접되어 있고 철근에는 돌륜이 형성되어 있어 망치가 조임쇠의 상단을 정확히 타격하기가 곤란한 불편이 있고 또 이와같은 연결구는 이어지는 두개의 철근의 연결부의 압축강도는 크게 향상시킬 수 있으나 인장강도가 낮은 중대한 결점이 있었던 것이다.Such a connector is relatively easy to install and inexpensive, but it is preferable, but when the clamping cylinder is struck by hammering the upper end of the fastener, the upper end of the fastener is close to the reinforcing bar, and the wheel is formed in the reinforcing bar, so that the hammer is fixed to It is inconvenient to hit hard and this connector can greatly improve the compressive strength of the connection of two subsequent reinforcing bar, but there was a significant drawback of low tensile strength.

본 고안은 이와같은 종래의 연결구에 있어서의 위와같은 결점을 제거하므로서 사용에 편리하게하고 연결부의 인장강도를 향상 시킬수 있도록 안출된 것으로 이를 첨부도면에 의하여 설명하면 다음과 같다.The present invention has been devised to facilitate the use and to improve the tensile strength of the connection by eliminating the above-mentioned defects in the conventional connector as described in the accompanying drawings as follows.

상측은 좁고 하측으로 갈수록 넓은 개구부가 형성된 압지통체(1)의 개구부 양측에 경사날개(2)(2')를 형성시키고 압지통체(1)에 다수의 통공(3)을 천설하며 상측은 좁고 하측으로 갈수록 넓은 조임쇠(4)의 양단을 내향으로 절곡하여 감입홈(5)(5')을 형성시키므로서 조임쇠(4)의 감입홈(5)(5')에 압지통체(1)의 경사날개(2)(2')가 끼워지도록 결합한후 조임쇠(4)의 상단을 망치로 때리면 압지통체(1)가 오무라져 연결되는 두개의 철근을 그 연결부에서 압지 연결되도록 하는 통상의 연결구에 있어서 조임쇠(4)의 상단에 수타편(受打片)(6)을 일체로 형성시켜 외향으로 절곡시키고 압지통체(1)의 중앙부에 투시공(7)을 친설하며 투시공(7)의 중심양측에 수평방향으로 표지선(8)(8')을 형성시킨다. 그리고 투시공(7)의 상하에 천설한 통공(3)(3')의 주연은 깔대기 모양으로 내형 절곡시키므로서 압지통체(1)의 내측으로 돌출부(9)가 형성되게 한다. 이와같이 구성된 본 고안은 먼저 아랫철근에 연결될 위의 철근 하단에 압지통체(1)를 끼우되 압지통체(1)의 중앙에 천설된 투시공(7)의 좌우에 표시된 (8)(8')표 지선과 윗철근의 하단선이 일치되게 한다음 조임쇠(4)의 감입홈(5)(5')이 압지통체(1)의 양경사날개(2)(2')에 끼워지도록 압지통체(1)의 위로부터 조임쇠(4)를 끼운다음 망치로 조임쇠(4)의 상단을 약간 때려서 윗철근과 연결구의 결합을 어느 정도 견고히하고 이어서 압지통체(1)의 하부에 아랫철근의 상단을 끼우고 조임쇠(4)의 상단을 망치로 때려서 압지통체(1)를 조여 압지통체(1)가 두개의 철근을 완강히 압지연결되게 하는 것이다.The upper side is narrow and the wider opening is formed toward the lower side, the inclined wings (2) (2 ') are formed on both sides of the opening of the blotting cylinder (1) and a large number of through holes (3) are laid in the blotting cylinder (1), the upper side is narrow and the lower side The inclined wings of the blotting cylinder 1 in the indentation grooves 5 and 5 'of the fastener 4 are formed by bending both ends of the fastening member 4 inward to form inward grooves 5 and 5'. (2) (2 ') is a fastener in a normal connector that allows the two bars to be pressed and connected at the connection by pressing the upper end of the fastener (4) with a hammer after joining to fit. 4) The hand piece 6 is integrally formed at the upper end of the bent piece and bent outwardly, and the see-through hole 7 is intimately installed in the center of the blotter cylinder 1, and is horizontal to both sides of the center of the see-through hole 7. The mark lines 8 and 8 'are formed in the direction. And the periphery of the through-hole (3) (3 ') laid in the upper and lower sides of the see-through hole (7) is formed inside the plunger cylinder (1) while bending the inner mold in the shape of a funnel. The present invention constituted as described above (8) (8 ') marked on the left and right of the see-through hole (7) installed in the center of the tack cylinder (1), but first put the tack cylinder (1) on the bottom of the upper rebar to be connected to the lower reinforcing bar Make sure that the branch line and the lower line of the upper reinforcing bar coincide with each other so that the indentation grooves 5 and 5 'of the fastener 4 fit into the two inclined vanes 2 and 2' of the tack cylinder 1. ) Fasten fasteners (4) from the top of the), and then slightly hit the top of the fasteners (4) with a hammer to secure the coupling of the upper reinforcement and the connector to some extent, and then insert the upper end of the lower reinforcement into the lower part of the blotter cylinder (1) The upper end of (4) with a hammer to tighten the blotting cylinder (1) so that the blotting cylinder (1) is firmly connected to the two steel bars.

그런데 본고안은 조임쇠(4)의 상단에 수타편(6)을 형성시켰으므로 망치를 조임쇠(4)의 상단을 때리기가 용이한 효과가 있으며 특히 철근에는 콘크리트와의 결착을 완강히 하기 위하여 돌륜이 형성되어 있으므로 종래에는 망치로 조임쇠(4)의 상단을 때릴때 망치가 철근에 접한 상태를 유지하면서 때리기가 곤란하므로 헛망치질을 하는 일이 흔하고 따라서 몸을 다치는 일이 있었던바 본고안은 수타편(6)을 일체로 형성시켰기 때문에 망치질이 극히 편리한 효과가 있다. 그리고 본고안의 연결구는 압지통체(1)의 통공(3)중 상하부의 통공(3)(3")의 내주연부를 내향으로 절곡하여 깔대기 모양으로 형성시켰기 때문에 압지통체(1)의 내면에 돌출부(9)가 형성되므로 압지통체(1)가 조여짐에 따라 돌출부(9)가 철근을 탄력있게 압박하므로 모르터가 통공내로 삽입되어 일단 결착된 두개의 철근은 양측으로 잡아당겨도 용이하게 분리되지 아니하여 비교적 인장강도를 크게할 수 있는 효과가 있다.However, this paper has formed the hand piece (6) on the upper end of the fastener (4) has an effect that is easy to hit the upper end of the fastener (4), especially in the reinforcing bar to form a stiffening bond with concrete Since it is difficult to hit the hammer while hitting the upper end of the fastener (4) with a hammer in the prior art, it is difficult to hit the hammer because it is common to injure the body. ) Is integrally formed, so hammering is extremely convenient. In addition, since the connector of the present invention is formed in the form of a funnel by bending inwardly the inner periphery of the upper and lower through holes (3) and (3 ") of the through holes (3) of the blotter cylinder (1), the protrusions ( 9) is formed, so as the blotting cylinder 1 is tightened, the protrusion 9 elastically presses the reinforcing bars so that the mortar is inserted into the through hole so that the two reinforcing bars once fixed are not easily separated by pulling on both sides. There is an effect that can increase the tensile strength relatively.
