Description
본 발명은 슬라브 등에 철근을 배근할 때 바닥으로부터 철근의 피복두께를 유지시키고 철근의 유동을 억제하기 위한 철근받침대에 관한 것이다.The present invention relates to a reinforcing bar for maintaining the coating thickness of the reinforcing bar from the floor and restraining the flow of the reinforcing bar when the reinforcing bar reinforcement.
철근받침대는 철근배근시 철근의 위치를 유지시키기 위한 수단으로 반드시 필요로 하는 것이고, 이러한 것으로는 시멘트블록으로 형성된 것, 금속으로 된 것, 합성수지로 형성된 것 등 재질면에서도 다양할 뿐 아니라, 그 형상에 있어서도 각종의 것들이 제조되고 있다. 종래의 철근받침대는 철근을 받침대의 홈에 형성된 받침부에 단순히 올려놓기만 하기 때문에 받침대와 철근을 결속선으로 묶어 주는 등 추가적인 작업을 필요로 한다. 더욱이 종래의 철근받침대는 상부철근 또는 하부철근의 어느 한 철근만을 받쳐주기 때문에 상부철근과 하부철근을 모두 받치기 위해서는 크기가 서로 다른 철근받침대를 준비하여야 한다는 번거로움이 있다. 간혹 상부철근과 함께 하부철근을 받쳐줄 수 있는 구조의 철근받침대가 출원되고는 있으나, 이 경우에도 하부철근은 철근 받침대의 측면에 형성된 홈부에 단순히 올려 놓는 구조로 되어 있어 상술한 바와 같은 별도의 고정수단을 추가하지 아니하면 콘크리트 타설중 쉽게 철근이 이탈되는 문제점이 있다. 또한 이와 같이 상하부 철근을 동시에 받쳐줄 수 있는 철근받침대의 경우에도 상부철근은 수직·수평철근을 모두 받칠 수 있는 반면, 하부철근은 어느 한 방향의 철근만을 받칠 수 있기 때문에 상하부 철근 모두가 교차하는 지점에서는 철근받침대의 사용이 불가능하다.The reinforcing bar is a necessary means to maintain the position of the reinforcing bar when the reinforcing bar is reinforcement, and it is not only diverse in terms of materials such as cement blocks, metals, synthetic resins, etc. Various things are also manufactured. Conventional reinforcing bar support simply adds the reinforcing bar to the support formed in the groove of the pedestal requires additional work such as tying the pedestal and the reinforcing bars with a binding line. Furthermore, since the conventional reinforcing bar supports only one of the upper or lower reinforcing bars, it is troublesome to prepare reinforcing bars having different sizes in order to support both the upper and lower reinforcing bars. Sometimes the reinforcing bar support of the structure that can support the lower reinforcement with the upper reinforcement, but even in this case, the lower reinforcing bar is simply put on the groove formed on the side of the reinforcing bar is a separate fixing means as described above If it is not added, there is a problem that the reinforcing bars easily fall out during concrete pouring. In addition, in the case of the reinforcing bar that can support the upper and lower rebars at the same time, the upper reinforcement can support both vertical and horizontal reinforcement, while the lower reinforcement can only support the reinforcing bar in either direction, so Reinforcement cannot be used.
따라서 본 발명은 상부철근과 하부철근을 함께 지지할 수 있도록 함과 아울러, 철근받침대에 철근을 쉽게 삽입되도록 하고, 또한 삽입된 철근은 쉽게 이탈되지 않는 철근받침대를 제공함에 있다.Therefore, the present invention allows to support the upper and lower reinforcing bars together, and to easily insert the reinforcing bar into the reinforcing bar support, and also to provide a reinforcing bar support that is not easily separated.

The body and the leg portion are formed integrally, and produced by injecting a synthetic resin. In the upper portion of the body 1, two mutually orthogonal first space portions 5 and second space portions 6, into which upper reinforcing rods intersecting each other longitudinally and laterally, are formed. The second space portion is deeply dug from the upper surface 20 of the body to form a second support 4 which extends from the front side of the body to the rear surface of the body forming the separation preventing piece 9. In contrast, the first space portion 5 is formed from the upper surface 20 of the body toward the side portion 17, but is formed to be shallower than the second support (4) of the upper reinforcing bar placed on the second support (3) Allow the top bar to rest on the bottom bar. The first pedestal and the second pedestal form a first through-hole 12 and a second through-hole communicating with the bottom so that the poured concrete can be filled in the interior space of the reinforcement. On the rear side of the body is formed a separation preventing piece (9) formed in a curve toward the front of the body in connection with the first support (3). The separation prevention piece (9) has a resilient force and the separation distance (a) with the upper surface 20 is slightly smaller than the diameter of the reinforcing bar is inserted so that the reinforcement is forced fit so that the upper reinforcement of the upper reinforcement is separated from the reinforcement To prevent it. In addition, the end of the separation prevention piece 9 is tapered toward the outside to facilitate the insertion of the reinforcing bar. The upper surface 20 formed in the upper front of the body has an insertion groove 19 to insert a control for adjusting the concrete coating thickness from the upper reinforcement. The adjuster may be a long elongated bar made of iron wire or synthetic resin.
다리부(2)는 몸체(1)의 하부에 아치형의 홈을 형성함으로써 이루어지는 사각 모서리부분의 4개로 구성된다.The leg portion 2 is composed of four square corner portions formed by forming an arcuate groove in the lower portion of the body 1.
도면 제2도는 철근받침대을 측면에서 바라본 형태이고, 도면 제3도는 정면에서 바라본 형태이다. 상기 다리부(2)의 내측공간에는 1쌍의 걸림편(10,11)이 상방을 향하여 가지처럼 형성되어 있다. 몸체의 측면부(17)에 형성된 제1걸림편(10)은 그 상부에 하부철근의 상단철근을 삽입시킬 수 있는 제3공간부(7)를 형성하며, 상기 삽입된 철근을 받쳐준다. 또한 몸체의 정면부(18)에 형성된 제2걸림편(11)은 그 상부에 하부철근의 하단철근을 삽입시킬 수 있는 제4공간부(8)를 형성하며, 상기 삽입된 철근을 받쳐준다. 상기 제3공간부(7)와 제4공간부(8)는 서로 철근이 교차될 수 있도록 공간의 높이를 달리하며, 삽입되는 철근의 위치에 따라 제3공간부(3)를 낮게 형성하고 제4공간부(4)를 높게 형성할 수도 있다. 상기 1쌍으로 형성된 각각의 걸림편(10, 11)은 각 걸림편간의 이격거리(b, c)를 철근의 직경보다 다소 작게하고 탄성력을 부여하여 억지끼움이 되도록 한다. 이와 같이 형성된 걸림편(10, 11)은 철근받침대를 고정시킨 상태에서 철근을 위로 당기기만 하면 철근이 쉽게 공간부(7, 8)에 삽입·고정된다. 다리부(2)의 바닥면에는 접지부(16)을 설치하여 바닥거푸집과의 접지면적을 작게 할 수 있다. 상기 접지부(16)는 다리부(2)와 일체로 형성할 수도 있고, 나사부 또는 걸림돌부 등을 이용한 착탈식으로 구성할 수도 있다. 또한 다리부(2)에 접지부(16)을 두지 않고, 다리부(2)의 바닥면을 콘크리트면에 노출시키고 상기 다리부(2)의 바닥면에 나사홈을 형성하여 향후 반자 등의 설치를 위한 인서트로도 활용할 수 있게 할 수도 있다. 상기 측면부(17)과 정면부(18)에는 제2통공(13)과 제3통공(14)을 두어 타설되는 콘크리트가 철근받침대의 내부에 충진되게 함으로써 철근받침대와 콘크리트구조물과의 결합을 견고하게 한다.FIG. 2 is a view of the reinforcing bar from the side, and FIG. 3 is a view from the front. In the inner space of the leg portion 2, a pair of engaging pieces 10 and 11 is formed upward like a branch. The first engaging piece 10 formed on the side portion 17 of the body forms a third space portion 7 into which the upper reinforcing bar of the lower reinforcing bar can be inserted, and supports the inserted reinforcing bar. In addition, the second catching piece 11 formed on the front portion 18 of the body forms a fourth space portion 8 into which the lower reinforcing bar of the lower reinforcing bar can be inserted, and supports the inserted reinforcing bar. The third space portion 7 and the fourth space portion 8 vary the height of the space so that the reinforcing bars can cross each other, and form a lower third space portion 3 according to the position of the reinforcing bars The four space part 4 can also be formed high. Each of the engaging pieces 10 and 11 formed as a pair has a distance (b, c) between the engaging pieces slightly smaller than the diameter of the reinforcing bar to give an elastic force to the interference fit. The engaging pieces 10 and 11 formed as described above are simply inserted and fixed in the spaces 7 and 8 by simply pulling up the reinforcing bar in the state where the reinforcing bar is fixed. The ground portion 16 may be provided on the bottom surface of the leg 2 to reduce the ground area with the floor formwork. The ground portion 16 may be formed integrally with the leg portion 2, or may be configured detachably using a screw portion or a locking protrusion. In addition, the ground portion 16 is not placed on the leg portion 2, and the bottom surface of the leg portion 2 is exposed to the concrete surface, and a screw groove is formed on the bottom surface of the leg portion 2 to install a half-width device in the future. It can also be used as an insert for. The side portion 17 and the front portion 18 have a second through hole 13 and a third through hole 14 so that the concrete to be poured is filled in the interior of the reinforcing bar to firmly bond the reinforcing bar to the concrete structure. do.
전술한 기술 내용으로부터 자명하게 알 수 있듯이, 본 발명의 철근받침대는 서로 직교하는 종횡방향의 상부철근과, 종횡방향의 하부철근을 동시에 받쳐 철근간격 및 철근의 피복두께를 유지시킬 수 있게 하며, 필요에 따라서는 2개의 직교하는 상부철근과 1개의 하부철근, 또는 1개의 상부철근과 서로 직교하는 2개의 하부철근 등 철근의 소요갯수 또는 위치에 따라 선택적으로 사용할 수 있도록 하므로 그 사용의 적용범위가 넓고, 하부의 철근이 용이하게 삽입됨과 아울러 쉽게 이탈되지 않도록 하는 효과를 가지고 있다. 또한 콘크리트의 타설시 철근의 상부피복두께를 확인하거나 유지시키는 것이 용이하고, 바닥거푸집에의 접지면적을 조절하여 탈형후 콘크리트 노출면을 매끈하게 할 수도 있고, 다리부의 바닥면을 노출시켜 향후 반자등의 설치시 인서트로도 활용이 가능하게 할 수도 있는 효과가 있다.As will be apparent from the above description, the reinforcing bar of the present invention simultaneously supports the upper and the lower bars in the longitudinal and transverse directions perpendicular to each other to maintain the reinforcing bars and the coating thickness of the bars. Depending on the required number or location of rebars, such as two orthogonal top bars and one bottom bar, or one top bar and two bottom bars orthogonal to each other, the scope of application is wide. In addition, the reinforcing bar of the lower part is easily inserted and has an effect of not being easily detached. In addition, it is easy to check or maintain the upper coating thickness of the reinforcement when pouring concrete, and to adjust the ground area to the floor formwork to smooth the exposed surface of the concrete after demolding, or to expose the bottom surface of the leg to become a half-width person in the future. There is an effect that can be used as an insert when installing.
