Abstract
본 발명은 CIP수직재와 어스앵커를 활용하는 가설 흙막이에 영구 벽체를 합벽 처리하는 작업이 용이한 Wale에 관한 것이다. CIP(5)등 가설 흙막이의 Wale은 굴토 완료 후 합벽을 시공하기 위하여 회수하거나 벽체 내에 사장시켜야 한다. Wale 회수를 위하여 어스앵커의 정착단을 풀면 안전사고가 발생하기 쉽고, Wale을 사장시키면 벽체의 두께가 증가한다. 따라서 재래식 H형강 Wale 대신 단면적이 작으면서도 강성이 커서 합벽 시공에 지장이 없는 Wale을 마련하기로 한다.The present invention relates to Wale, which is easy to work with plywood permanent wall to the temporary soil wall using CIP vertical material and earth anchor. Wale of temporary cinders, such as CIP (5), should be recovered or left in the wall after construction to complete the plywood. Unfastening the anchoring end of the earth anchor to recover the wale is likely to cause a safety accident. Therefore, instead of the conventional H-shaped steel Wale, the cross section is small and the rigidity is large, so Wale will be prepared without any problems in the construction of plywood.
도 1과 2는 CIP에 수평 방향으로 철근트러스 웨일(1)을 부착하고 Wale에 어스앵커(3)를 박은 것이다. 철근트러스는 4개의 철근 현재(M1-M4) 사이에 철근 사재(D1-D3)와 수직재(V) 및 지압판(P1, P2)을 용접한 것이다. 또한 사춤 모르터(7)는 CIP와 철근트러스 웨일(1)을 밀착시키는 역할을 한다. 철근트러스는 충실 단면이 아니므로 철근콘크리트 합벽 시공이 용이하다.1 and 2 attach the reinforcement truss wale 1 to the CIP in the horizontal direction and embed the earth anchor 3 in Wale. Reinforcing truss is the welding of the reinforcing bar material (D1-D3), the vertical material (V) and the pressure plate (P1, P2) between the four rebar current (M1-M4). In addition, the filling mortar 7 serves to closely contact the CIP and the reinforcing truss wales 1. Since the reinforced truss is not a solid cross section, it is easy to construct reinforced concrete plywood.
본 발명의 철근트러스 웨일(1) 합벽 공법을 활용하면 합벽을 CIP 등 흙막이 벽에 밀착 시공할 때 철근콘크리트 공사가 쉽고 합벽 두께도 최소한으로 줄일 수 있어서 경제적이다.Using the reinforced truss wales (1) plywood method of the present invention when the plywood wall is in close contact with the earth wall, such as CIP, reinforced concrete construction is easy and economical because it can reduce the thickness of the ply wall to a minimum.
Description
CIP등 가설 흙막이는 수직 방향 강성은 크지만 수평 방향 휨 내력이 없으므로 굴토해 감에 따라 적당한 간격으로 Wale을 설치하여야 한다. 그러나 굴토 작업을 마치고 영구 구조체인 합벽을 시공하기 위해서는 Wale을 회수하거나 벽체 내에 사장시켜야 한다. Wale을 회수하려면 어스앵커의 정착단을 일시 풀어야 하는데 그 과정에서 안전사고가 발생하는 예가 많고, Wale을 사장시키려면 벽체의 두께를 Wale이 차지하는 두께만큼 추가해야 철근 배근과 콘크리트 부어넣는 작업이 원활해진다.Temporary mudstones such as CIP have great rigidity in the vertical direction but have no bending strength in the horizontal direction. However, in order to complete the construction of plywood, which is a permanent structure, Wale must be recovered or left in the wall. In order to recover Wale, it is necessary to temporarily loosen the anchor anchor of the earth anchor. In the process, there are many cases of safety accidents.In order to replace Wale, reinforcement of reinforcement and concrete is smoothed by adding wall thickness as much as Wale occupies. .
재래식 Wale은 대부분 H형강을 눕혀서 수평 방향으로 배열하는데 철근콘크리트 벽체를 가설 흙막이와 합벽으로 밀착 시공하려면 Wale에 철근을 관통시킬 구멍을 뚫거나 철근을 용접하여야 한다. 위 번거로움을 해소하기 위해서는 단면적이 작으면서도 강성이 커서 위 번거로움이 없는 Wale을 마련하는 것이 기술적 과제이다.Conventional wales are laid horizontally with H-beams laid horizontally. In order to construct the reinforced concrete walls tightly with temporary mud walls and plywood walls, the wales must be drilled or welded to rebar. In order to solve the above hassles, it is a technical problem to prepare a Wale which has a small cross-sectional area and high rigidity without any hassles.
도 1과 2는 가설 흙막이 CIP(5)의 한 쪽 흙을 제거함으로 인하여 유발되는 편측 토압에 저항하기 위하여 철근트러스 웨일(1)을 수평 방향으로 CIP에 부착하고 Wale에는 적당한 간격(구조계산으로 정함)으로 어스앵커(3)를 박은 것이다. 철근트러스 웨일(1)은 4각형의 각 구석에 철근 현재(M1, M2, M3, M4)를 배열하고 이들 사이에 사재(D1, D2, D3)와 수직재(V) 및 지압판(P1, P2)을 용접한 것이다. 각 현재는 주로 휨모멘트로 인한 압축, 인장력에 저항하고 사재는 전단력에 대응하며 수직재는 트러스의 형상 유지, 지압판은 CIP의 하중을 철근트러스에 전달하는 매개체로 활용한다. 또한 사춤 모르터(7)는 CIP의 단면 형태가 원형이며 중심축이 직선을 벗어나게 시공되었을 경우 철근트러스 웨일을 제대로 밀착시키는 매개체 역할을 한다. 철근트러스 웨일(1)은 각 부재들 사이가 공간이므로 그 사이에 철근을 배근하고 콘크리트를 부어넣기에 편하다.Figures 1 and 2 attach the reinforced truss wales 1 to the CIP in the horizontal direction and resist the proper spacing (structural calculations) in Wale to resist the unilateral earth pressure caused by removing the soil on one side of the CIP (5). ) Is embedded in the earth anchor (3). Reinforced truss wales (1) arranges reinforcing bars (M1, M2, M3, M4) in each corner of the quadrilateral, and between them (D1, D2, D3), vertical (V) and pressure plate (P1, P2). Is welded. Each current mainly resists the compressive and tensile forces due to the bending moment, the sand material corresponds to the shear force, the vertical material maintains the shape of the truss, and the pressure plate is used as a medium to transfer the load of the CIP to the reinforcing truss. In addition, the filling mortar (7) has a circular cross-sectional shape of the CIP when the central axis is constructed out of a straight line serves as a medium to properly adhere the reinforced truss wales. Since the reinforcement truss wales 1 is a space between each member, it is convenient to reinforce reinforcement and to pour concrete therebetween.
합벽을 바닥 슬래브 등으로 영구 지지하는 경우 합벽 공사 후 어스앵커(3)를 회수하기도 한다. 도 6은 그런 경우 어스앵커가 철근트러스 웨일(1)을 통과하여 합벽 외측에 정착되도록 한 것이며 이 때 어스앵커가 합벽(6) 콘크리트에 묻히지 않게 하기 위하여 철근트러스 내에 강관(8)을 용접하여 강선 슬리브로 삼는다.When the plywood is permanently supported by a floor slab or the like, the earth anchors 3 may be recovered after the plywood construction. FIG. 6 is such that the earth anchors pass through the reinforcing truss wales 1 to be settled outside the plywood wall, in which case the steel anchors 8 are welded into the reinforcing truss to prevent the earth anchors from being buried in the plywood wall concrete. Make a sleeve.
