Description

철근간격유지구{SPACER BETWEEN REINFORCING RODS}Rebar spacing zone {SPACER BETWEEN REINFORCING RODS}

본 고안은 철근간격유지구에 관한 것으로, 보다 상세하게는 철근콘크리트 구조물을 형성하기 위해서 수평철근을 배열할 때 그 간격을 유지시켜 줄 수 있도록 하되 구조가 간단하고, 쉽게 이탈되지 않도록 한 철근간격유지구에 관한 것이다. The present invention relates to a rebar spacing zone, and more specifically, to maintain the spacing when arranging horizontal rebars to form a reinforcement concrete structure, the structure is simple and the rebar spacing is not easily separated. It's about a phrase.

철근콘크리트로 구조물을 형성할 때에는 철근을 설치한 후에 주변으로 거푸집을 형성하고, 상기 거푸집의 내부로 시멘트, 모래 및 자갈을 일정한 비율로 물과 함께 혼합시킨 콘크리트를 충진한 후 양생시켜서 형성한다.When forming the structure with reinforced concrete, form the formwork after installing the reinforcing bar, and by filling the concrete in which the cement, sand, and gravel mixed with water at a constant ratio to form the curing and curing.

상기와 같이 철근콘크리트로 구조물을 형성할 때에는 철근의 배열이 매우 중요한데, 상기 철근은 건축법이 규정하고 있는 간격으로 일정하게 배열해 주어야만 철근콘크리트 구조물이 양호하고 견고하게 양생될 수 있다.When forming a structure with reinforced concrete as described above, the arrangement of the reinforcing bar is very important, the reinforcement concrete structure can be cured well and firmly only if the reinforcement is arranged at regular intervals prescribed by the building law.

상기 철근콘크리트 구조물에서 수평면을 형성할 때에는 다수개의 철근을 여러단으로 형성하는데 이때 상하단에 위치하는 철근과 철근 사이의 간격을 유지시키기 위해서 철근간격유지구가 사용된다.When forming a horizontal plane in the reinforced concrete structure, a plurality of reinforcing bars are formed in a plurality of stages. In this case, a reinforcing bar maintenance zone is used to maintain a gap between reinforcing bars and reinforcing bars located at the upper and lower ends.

종래의 철근간격유지구는 도 1과 같이 대한민국특허청 등록실용신안 제0231222호에 개시된 바 있는데, 그 구조를 간단히 살펴보면, 수직으로 소정의 길이를 가지며 하단이 90°뒤틀려 형성되는 스페이서와; 상기 스페이서의 상단으로부터 수평으로 소정길이 연장형성된 수평이격부재와; 상기 수평이격부재의 상단에 수직상향으로 형성되되, 격자철근 중 어느 하나의 2지점에 고정되는 제1 및 제2철근 고정부와; 상기 스페이서의 하단에 형성되는 제3철근고정부로 구성된다. Conventional rebar spacing zone is disclosed in the Republic of Korea Patent Application Utility Model No. 0231222, as shown in Figure 1, briefly look at the structure, the spacer has a predetermined length vertically and the bottom is twisted 90 °; A horizontal spacer formed to extend a predetermined length horizontally from an upper end of the spacer; First and second reinforcing bar fixing parts formed vertically on an upper end of the horizontal spacer member and fixed to two points of any one of the grid reinforcing bars; It is composed of a third rebar fixing portion formed on the lower end of the spacer.

그러나, 상기 종래의 철근간격유지구는 철근에 제1, 2, 3 철근고정부에서 철근이 삽입되는 방향이 대각방향으로 형성되고, 삽입되는 표면이 매우 부드럽게 형성되어 있어서, 조금만 힘을 받더라도 철근이 쉽게 빠져나는 문제점이 있었고, 제작이 복잡해서 생산원가가 많이 소요되는 문제점이 있었다.However, in the conventional rebar spacing zone, the rebar is inserted into the reinforcing bars in the first, second, and third rebar fixing directions in a diagonal direction, and the surface to be inserted is formed very smoothly, so that the reinforcing bars are easily subjected to a slight force. There was a problem to escape, the production was complicated, the production cost was a lot of problems.

상기한 문제점을 해결하기 위해서, 본 고안은 철근과 철근사이에 쉽게 설치할 수 있지만 쉽게 빠지지 않고 단단하게 고정될 수 있을 뿐만 아니라, 구조가 간단하여 생산원가를 줄일 수 있는 철근간격유지구를 제공함에 그 목적이 있다.In order to solve the above problems, the present invention can be easily installed between the reinforcing bar and the reinforcing bar, but can not be easily fixed and firmly fixed, as well as providing a rebar spacing zone that can reduce the production cost due to its simple structure. There is a purpose.

상기한 목적을 달성하기 위해서, 본 고안은 일반적인 철사를 S자 형태로 형성하는 철근간격유지구에 있어서,In order to achieve the above object, the present invention in the reinforcement interval holding zone to form a general wire in the form of S,

철사를 굽혀서 일체로 형성되되, 직선으로 형성되는 간격유지부와; 상기 간격유지부의 끝단에 연장되어 일측으로 제1만곡부와 제2만곡부로 두번 절곡된 하단만곡부와; 상기 간격유지부의 타단에 연장되어 상기 하단만곡부와 대각방향으로 제3만곡부와 제4만곡부가 두번 절곡되어 형성된 상단만곡부가 형성된 것을 특징으로 한다.Bending the wire is formed integrally, the gap maintaining portion is formed in a straight line; A lower curved portion extending to an end of the gap maintaining portion and bent twice into a first curved portion and a second curved portion to one side; The upper end curved portion is formed by extending to the other end of the interval maintaining portion is formed by bending the third curved portion and the fourth curved portion twice in the diagonal direction with the lower curved portion.

이하, 본 고안을 바람직한 실시예와 첨부된 도면을 참조하여 상세하게 설명하면 다음과 같다.Hereinafter, described in detail with reference to the preferred embodiments and the accompanying drawings as follows.

상기 철사는 3mm정도의 두께를 가진 것으로 간격유지에 필요한 길이와 만곡되는 부분의 길이를 합하여 적당한 길이로 잘라서 사용하는 것이 적당하다. 일반적으로 200~300mm정도의 길이로 절단하는 것이 적당하다.The wire has a thickness of about 3mm, and it is appropriate to cut the wire to a suitable length by adding the length required for maintaining the gap and the length of the curved portion. In general, it is appropriate to cut the length of about 200 ~ 300mm.

상기 간격유지부(100)의 길이는 건축법이 규정하는 길이로 형성하고, 상기 간격유지부(100)에 의해서 철근(400)의 간격이 정해지는 것이다. The length of the spacing holding part 100 is formed to a length prescribed by the building method, and the spacing of the reinforcing bar 400 is determined by the spacing holding part 100.

상기 간격유지부(100)의 제1만곡부(210)는 끝단이 180도로 꺾일 수 있도록 만곡하되, 상기 만곡되는 부분은 지름이 약 16~18mm정도의 원주로 만곡된다. The first curved portion 210 of the interval maintaining portion 100 is curved so that the end can be bent 180 degrees, the curved portion is curved in a circumference of about 16 ~ 18mm in diameter.

The lower insert 230 is formed.

상기 하단삽입부(230)의 간격(d)은 9.5~10.3mm로 제작하는 것이 적당한데, 이는 철근(400)을 10~16mm로 사용하기 위한 것이고, 하단삽입부(230)를 통과할 때 철사의 탄성으로 인해서 철근(400)이 삽입되기는 하지만, 고정부(240)에 의해서 잘 빠지지 않도록 하기 위한 것이다. The interval d of the lower insert 230 is suitable to manufacture a 9.5 ~ 10.3mm, which is to use the reinforcement 400 in 10 ~ 16mm, the wire when passing through the lower insert 230 Due to the elasticity of the reinforcing bar 400 is inserted, but is not intended to fall well by the fixing part 240.

특히, 상기 제2만곡부(220)와 연장되는 끝단은 절단된 형태로 철근(400)과 수직으로 만나기 때문에 마찰에 의해서 잘 빠지지 않도록 된 것이다.In particular, the end portion extending from the second curved portion 220 is perpendicular to the reinforcing bar 400 in a cut form, so that the end portion thereof does not fall out by friction.

상기 상단만곡부(300)는 하단만곡부(200)와 동일한 형태로 형성되나 대각방향으로 대칭되도록 형성된다. The upper curved portion 300 is formed in the same shape as the lower curved portion 200 but is formed to be symmetric in a diagonal direction.

상기 간격유지부(100)의 제3만곡부(310)는 끝단이 180도로 꺾일 수 있도록 만곡되되, 상기 만곡되는 부분은 지름이 약 16~18mm정도의 원주로 만곡된다. The third curved portion 310 of the space maintaining portion 100 is curved so that the end can be bent 180 degrees, the curved portion is curved in a circumference of about 16 ~ 18mm in diameter.

상기 제3만곡부(310)와 연장되어 간격유지부(100)와 나란하게 일정길이로 형성되다가 제4만곡부(320)에서 또다시 180도로 꺾일 수 있도록 만곡되되, 상기 만곡되는 부분은 지름이 약 10~12mm정도의 원주로 만곡된다.The third curved portion 310 is formed to have a predetermined length in parallel with the interval maintaining portion 100 and bent to be bent 180 degrees at the fourth curved portion 320 again, the curved portion having a diameter of about 10 It is curved in a circumference of about 12 mm.

상기 제4만곡부(320)와 연장되어 간격유지부(110)와 나란하게 일정길이로 고정부(340)가 형성되는데, 상기 고정부(240)와 간격유지부(110)에는 일정한 간격이 형성되는 상단삽입부(330)가 형성된다.The fixed portion 340 is formed to extend in parallel with the fourth curved portion 320 and the interval maintaining portion 110 at a predetermined length, and the fixed portion 240 and the interval maintaining portion 110 are formed with a predetermined interval. The upper inserting portion 330 is formed.

상기 상단삽입부(330)의 간격(d)은 9.5~10.3mm로 제작하는 것이 적당한데, 이는 철근(400)을 10~16mm로 사용하기 위한 것이고, 상단삽입부(330)를 통과할 때 철사의 탄성으로 인해서 철근(400)이 삽입되기는 하지만, 잘 빠지지 않도록 하기 위한 것이다. 특히, 상기 제4만곡부(320)와 연장되는 끝단은 절단된 형태로 철근(400)과 수직으로 만나기 때문에 마찰에 의해서 잘 빠지지 않도록 된 것이다.The interval d of the upper insertion portion 330 is suitable to manufacture the 9.5 ~ 10.3mm, which is to use the reinforcement 400 10 to 16mm, when passing through the upper insertion portion 330 Due to the elasticity of the reinforcement 400 is inserted, but not to fall well. In particular, the end portion extending from the fourth curved portion 320 is perpendicular to the rebar 400 in a cut form, so that the end portion extending from the fourth curved portion 320 does not fall out by friction.

상기한 것과 같이, 본 고안의 철근간격유지구에 의하면, 철근과 철근사이에 쉽게 설치할 수 있지만 쉽게 빠지지 않고 단단하게 고정될 수 있을 뿐만 아니라, 구조가 간단하여 생산원가를 줄일 수 있는 효과가 있다.As described above, according to the rebar spacing zone of the present invention, it can be easily installed between the reinforcing bar and the reinforcing bar, but can not be easily fixed and firmly fixed, as well as the structure has a simple effect of reducing the production cost.
