Description

나선형 전단보강체 및 이를 이용한 슬래브 철근의 배근구조{Spiral type shear reinforcement device and bars arrangement structure thereof}Spiral type shear reinforcement device and bars arrangement structure

본 발명은 무량판구조에서 기둥과 슬래브 접합부의 전단보강에 관한 것으로, 더욱 상세하게는 최소의 철근량으로 전단보강 효과를 극대화할 수 있는 것은 물론 슬래브 철근의 배근방향에 유연하게 대응하면서 적용할 수 있는 전단보강체와 이를 바람직하게 이용한 슬래브 철근의 배근구조에 관한 것이다.
The present invention relates to the shear reinforcement of the column and the slab joint in a flat plate structure, and more specifically, it can be applied to flexibly correspond to the reinforcement direction of the slab reinforcement as well as to maximize the shear reinforcement effect with a minimum amount of rebar. It relates to a shear reinforcement and the reinforcement structure of the slab reinforcement using the same.

무량판구조는 보 없이 슬래브만으로 바닥을 구성하고 그 슬래브의 하중을 직접 기둥에 전달하는 구조방식이다. 무량판구조는 기둥 주변으로 과도한 응력 집중 현상이 발생하기 때문에 슬래브가 펀칭 전단파괴될 우려가 큰데, 전단파괴를 억제하기 위해 통상 무량판구조에서는 기둥과 슬래브의 접합부를 전단 보강한다.Flat plate structure is a structural method that consists of the slab only without a beam and transfers the load of the slab directly to the column. The flat plate structure is highly susceptible to punching shear failure due to excessive stress concentration around the column. In order to suppress the shear failure, the flat plate structure generally shear-reinforces the joint between the column and the slab.

전통적인 전단 보강방법에는 기둥 주위에 지판(drop panel)과 주두(capital)를 시공하여 단면을 확대하는 방법이 있으나, 이 방법은 지판이나 주두 형성을 위한 거푸집을 설치해야 하는 등 시공성이 떨어진다. 이에 최근에는 슬래브 철근 배근과정에서 기둥과의 접합부에 전단보강체를 설치하여 전단 내력을 증가시키는 방법이 주로 적용되고 있다. 도 1은 종래 전단보강체를 설치하여 전단 보강한 다양한 방식을 보여준다.Conventional shear reinforcement method has a method of expanding the cross-section by installing a drop panel and a capital around the column, but this method is inferior in construction, such as the need to install formwork for forming the fingerboard or the head. Recently, a method of increasing shear strength by installing a shear reinforcement at a junction with a column in slab reinforcement is mainly applied. Figure 1 shows a variety of ways to shear reinforcement by installing a conventional shear reinforcement.

도 1(a)는 슬래브철근에 스티럽(띠철근)을 감아 이것으로 전단내력을 보강한 방식이다. 이 방식은 통상의 철근 자재를 사용하는 방식이므로 자재 수급이 용이하고 경제적이라는 장점이 있다. 그러나 이 방식은 스티럽이 슬래브 철근의 바깥 둘레를 감싸기 때문에 피복두께를 적절히 유지하기 어렵고, 스티럽 결속과 관련한 현장 작업이 번거로워 시공성이 좋지 못하다는 단점이 있다. Figure 1 (a) is a method of reinforcing the shear strength by winding a styrup (strip reinforcing bar) on the slab rebar. This method has a merit that it is easy and economical to supply materials because it uses a conventional rebar material. However, this method has a disadvantage in that it is difficult to maintain the coating thickness properly because the stirup wraps around the outer circumference of the slab reinforcing bar, and the construction work is difficult because of the cumbersome field work related to the stirrer binding.

도 1(b)는 H형강 또는 채널을 종,횡으로 설치하여 이것으로 전단내력을 보강한 방식이다. 이 방식은 형강재의 사용에 따라 필요 이상의 강재가 소요됨은 물론 건물의 자중이 증가하고, 콘크리트의 타설시 밀실한 충전을 위해 세심한 주의가 필요하다는 단점이 있다.Figure 1 (b) is a method of reinforcing the shear strength by installing the H-shaped steel or channel vertically and horizontally. This method has disadvantages that it takes more steel than necessary according to the use of the section steel, and the weight of the building increases, and careful attention is required for tight filling of concrete.

도 1(c)는 평철판에 다수의 스터드 볼트를 용접한 전단보강체를 설치하여 이것으로 전단내력을 보강한 방식이다. 이 방식은 다수의 스터드 볼트를 일정 간격으로 이격시키면서 용접해야 하는 등 전단보강체의 제작이 번거롭고, 사선방향으로 진행되는 전단파괴에 효과적으로 대응하지 못한다는 단점이 있다.Figure 1 (c) is a method of reinforcing the shear strength by installing a shear reinforcing body welded a plurality of stud bolts on a flat iron plate. This method is cumbersome to produce a shear reinforcement, such as welding a plurality of stud bolts spaced at regular intervals, there is a disadvantage that it does not effectively cope with the shear failure in the diagonal direction.

도 1(d)는 철근을 입체 트러스 모양으로 조립한 전단보강체(1본의 상부근, 2본의 하부근, 2본의 래티스근)를 설치하여 이것으로 전단내력을 보강한 방식이다. 이 방식은 사선방향으로 진행되는 전단파괴에 효과적으로 대응할 수 있다는 이점이 있으나, 철근량이 많아져 경제적이지 못하고 전단보강체의 제작이 복잡하다는 단점이 있다. 뿐만 아니라 전단보강체와 배력근 사이에 간섭이 발생하기 때문에 전단보강체를 기둥 주변에 사방으로 설치하지 못하고 배력근과 평행한 방향으로 기둥을 관통하도록 설치해야만 하는 단점이 있다. Figure 1 (d) is a method of reinforcing the shear strength by installing a shear reinforcing body (one upper bar, two lower bars, two lattice muscles) assembled the reinforcing bar in a three-dimensional truss shape. This method has the advantage that it can effectively cope with the shear failure in the oblique direction, but has the disadvantage that the amount of rebar is not economical and the production of shear reinforcement is complicated. In addition, because the interference between the shear reinforcement and the reinforcement is generated, there is a disadvantage that the shear reinforcement should not be installed in all directions around the column, but must be installed to penetrate the column in a direction parallel to the reinforcement.

도 1(e)는 철근을 평면 트러스 모양으로 조립한 전단보강체(1본의 상부근, 1본의 하부근, 2본의 래티스근)를 설치하여 이것으로 전단내력을 보강한 방식이다. 이 방식은 도 1(d)의 입체 트러스에 비해 철근량을 줄일 수 있는 이점이 있으나, 전단보강체의 제작 문제는 물론 전단보강체의 일방향 설치 문제는 그대로 내재한다.
FIG. 1 (e) is a method of reinforcing shear strength by installing shear reinforcing bodies (one upper bar, one lower bar, and two lattice bars) in which reinforcing bars are assembled in a flat truss shape. This method has the advantage of reducing the amount of rebar compared to the three-dimensional truss of Figure 1 (d), but the problem of the one-way installation of the shear reinforcement as well as the problem of manufacturing the shear reinforcement.

도 2 내지 도 4는 본 발명에 따른 나선형 전단보강체에 대한 다양한 실시예를 보여주는데, 본 발명에 따른 나선형 전단보강체(100a, 100b, 100c)는 나선근(110), 1본의 상부근(120), 1본의 하부근(130)을 기본 구성으로 한다. 특히 본 발명은 장방형 타원 나선으로 형성된 나선근(110)을 필수적인 구성으로 포함한다는데 기술적 특징이 있다. 2 to 4 show various embodiments of the helical shear reinforcement body according to the present invention, the helical shear reinforcement body (100a, 100b, 100c) according to the present invention is a spiral root 110, one upper root ( 120) and one lower root 130 as a basic configuration. In particular, the present invention has a technical feature to include as an essential configuration the spiral root 110 formed of a rectangular ellipse helix.

본 발명에서 나선근(110)은 길이방향을 따라 나선으로 굽어지는 것으로, 너비방향 정면에서 볼 때 너비보다 높이가 크면서 너비방향으로 원호(原戶)를 그리는 장방형(長方形) 타원 나선으로 형성된 부재이다(도 2(b) 및 도 3(b) 참조). 이러한 나선근(110)은 길이방향 측면에서 보면 도 2(c) 및 도 3(c)에서와 같이 반복적인 삼각 트러스를 형성하며, 이에 따라 나선근(110)은 사선방향의 전단파괴에 효과적으로 대응하는 구성이 된다.In the present invention, the spiral root 110 is bent in a spiral along the longitudinal direction, a member formed of a rectangular elliptic spiral that draws an arc in the width direction while having a height greater than the width when viewed from the front in the width direction. (See FIGS. 2 (b) and 3 (b)). The spiral root 110 forms a repetitive triangular truss as shown in Figs. 2 (c) and 3 (c) when viewed in the longitudinal direction, whereby the spiral root 110 effectively copes with the shear failure in the diagonal direction. It becomes the structure to say.

나선근(110)은 슬래브 철근의 상·하부 주근(BR1, TR1) 간격만큼의 높이로 제작하며, 그래야 피복두께를 확보할 수 있고 아울러 나선근(110)의 사선방향 요소에 의한 전단보강효과를 극대화할 수 있다. 또한 나선근(110)은 원호의 내부 직경(D)이 나선근(110) 직경(d)의 4배로 가공하는 것(D=4d)이 바람직한데, 그래야 나선근(110)의 너비를 최소화하면서 나선근(110)의 안정적인 굽힘 가공을 유도할 수 있다. 나선근(110)의 너비가 최소가 될 때 전단보강체(100a, 100b, 100c)의 효율적인 설계가 가능하다.The spiral root 110 is manufactured at the same height as the spacing of the upper and lower main bars (BR1, TR1) of the slab reinforcing bar, so that the cover thickness can be secured, and the shear reinforcement effect is caused by the diagonal element of the spiral bar 110. It can be maximized. In addition, it is preferable that the spiral root 110 processes the inner diameter (D) of the arc to four times the diameter (d) of the spiral root (D), so that the width of the spiral root 110 is minimized. Stable bending of the spiral root 110 can be induced. Efficient design of the shear reinforcement (100a, 100b, 100c) is possible when the width of the spiral root 110 is minimum.

도 2는 본 발명에 따른 나선형 전단보강체(100a)에 대한 제1실시예인데, 제1실시예는 슬래브 철근 중 배력근(BR2, TR2)과 동일한 방향으로 설치하기 위해 제안된 단위 나선형 전단보강체(100a)의 예이다. 제1실시예는 배력근((BR2, TR2)과 동일한 방향으로 평행하게 설치하기 때문에 배력근(BR2, TR2)과의 간섭문제가 일어나지 않는다. 이에 따라 제1실시예는 상부근(120)과 하부근(130)이 각각 나선근(110)의 길이방향을 따라 나선근(110)의 상부 고점(高點)과 하부 저점(邸點)에 내접하게 배치되어 용접 접합된다.Figure 2 is a first embodiment of the helical shear reinforcement (100a) according to the present invention, the first embodiment is a unit helical shear reinforcement proposed for installation in the same direction as the reinforcement bars (BR2, TR2) of the slab reinforcement It is an example of the sieve 100a. Since the first embodiment is installed in parallel in the same direction as the back muscles BR2 and TR2, there is no problem of interference with the back muscles BR2 and TR2.

Since the second embodiment is installed in the direction intersecting with the back muscles BR2 and TR2, the interference problem with the back muscles BR2 and TR2 occurs. Accordingly, in the second embodiment, the upper and lower roots 120 and the lower roots 130 are internally disposed at the upper side of one side of the spiral root 110 and the lower side of the other side along the longitudinal direction of the spiral root 110, respectively, and thus are welded to each other. do. Considering the interference with the back muscles BR2 and TR2, the upper muscle 120 is joined below the diameter of the back muscles BR2 and TR2 at the upper high point of the spiral muscle 110, and the lower muscle 130 is the spiral. At the lower high point of the root 110 is to join above the diameter of the back muscles (BR2, TR2).

도 4는 본 발명에 따른 나선형 전단보강체(100c)에 대한 제3실시예인데, 제3실시예는 단위 나선형 전단보강체(100a, 100b)를 집합화한 집합 나선형 전단보강체(100c)의 예이다. 제3실시예는 단위 나선형 전단보강체(100a, 100b) 복수 개를 병렬로 이격 배치하고 단위 나선형 전단보강체(100a, 100b) 상호 간을 연결선(140)으로 연결하는 것으로 완성할 수 있다. 이러한 집합 나선형 전단보강체(100c)는 설치작업을 일원화할 수 있어 작업성에 유리한 형태가 된다. 도 4는 도 2의 단위 나선형 전단보강체(100a)로 완성한 예인데, 보는 바와 같이 연결선(140)을 나선근(110)에서 연장시켜 이용하고 있다.Figure 4 is a third embodiment of the helical shear reinforcement (100c) according to the present invention, the third embodiment of the aggregate helical shear reinforcement (100c) of the unit helical shear reinforcement (100a, 100b) Yes. The third embodiment may be completed by arranging a plurality of unit helical shear reinforcement (100a, 100b) spaced in parallel and connecting the unit helical shear reinforcement (100a, 100b) to each other by a connection line (140). The aggregate helical shear reinforcement (100c) can be unified installation work to form a favorable workability. 4 is an example completed with the unit spiral shear reinforcement 100a of FIG. 2, and as shown, the connecting line 140 is extended from the spiral root 110 and used.

도 5a 내지 도 5d는 도 2와 도 3의 나선형 전단보강체(100a, 100b)를 이용하여 슬래브 철근을 배근한 상태를 나타낸다. 보는 바와 같이 주근(BR1, TR1)과 배력근(BR2, TR2)을 격자로 교차시키면서 슬래브 상·하부철근을 배근하고, 기둥(C) 주변으로 슬래브 상·하부철근 사이에 나선형 전단보강체(100a, 100b)를 배근한다. 다만 도 2의 나선형 전단보강체(100a)는 배력근(BR2, TR2)과 동일한 방향으로 배근하고, 도 3의 나선형 전단보강체(100b)는 주근(BR1, TR1)과 동일한 방향으로 배근한다. 배근순서는 슬래브 하부철근을 배근한 후 나선형 전단보강체(100a, 100b)를 슬래브 하부철근 위에 얹어 배근하고 슬래브 상부철근을 배근하는 과정으로 진행하며, 나선형 전단보강체(100a, 100b)는 결속선으로 슬래브 하부철근에 묶어 고정한다. 단위 나선형 전단보강체(100a, 100b) 대신에 앞서 살펴본 도 4와 같은 집합 나선형 전단보강체(100c)를 이용할 수 있음은 물론이다. 이로써 도 5a 내지 도 5d에서와 같이 나선형 전단보강체가 기둥 주변에 사방으로 배치된다.

As shown, the upper and lower reinforcing bars of the slab are reinforced while intersecting the main bars BR1 and TR1 with the reinforcement bars BR2 and TR2, and the spiral shear reinforcement 100a is disposed between the upper and lower bars of the slab around the column C. , 100b). However, the spiral shear reinforcement 100a of FIG. 2 reinforces in the same direction as the reinforcement bars BR2 and TR2, and the spiral shear reinforcement 100b of FIG. 3 reinforces in the same direction as the main roots BR1 and TR1. In order to reinforce the slab bottom reinforcing bar, the spiral shear reinforcements (100a, 100b) are placed on top of the slab bottom reinforcement, and the slab upper reinforcing bars are progressed. Tie and fasten it to the slab lower rebar. Instead of the unit helical shear reinforcement (100a, 100b) it is a matter of course that the aggregate helical shear reinforcement (100c) as shown in Figure 4 can be used. As a result, as shown in FIGS. 5A to 5D, the helical shear reinforcing body is disposed all around the column.
