복층형 구조의 슬래브 거푸집 및 그 지지방법{SLAB FORM FOR MULTI-LAYER STRUCTURE AND SUPPORTING METHOD THEREOF}Slab formwork with double-layer structure and its supporting method {SLAB FORM FOR MULTI-LAYER STRUCTURE AND SUPPORTING METHOD THEREOF}

본 발명은 복층형 구조의 슬래브 시공을 위한 거푸집 및 이를 지지하기 위한 방법으로, 수직 내력벽 양쪽에 트러스 구조를 선 시공하여 가설지주 없이 슬래브 거푸집을 지지하여 하층 슬래브의 경화유무에 상관없이 상층 슬래브의 콘크리트 타설 작업이 가능하도록 된 복층형 구조의 슬래브 거푸집 및 그 지지방법에 관한 것이다.The present invention is a formwork for a slab construction of a multi-layered structure and a method for supporting the same, concrete construction of the upper slab regardless of the hardening of the lower slab by supporting the slab formwork without preliminary support by installing the truss structure on both sides of the vertical bearing wall The present invention relates to a slab formwork having a multi-layered structure in which work can be performed and a method of supporting the same.

일반적으로 철근콘크리트 구조에서 철근콘크리트 슬래브를 축조하는 가장 일반적인 방법은, 도 1에서와 같이 콘크리트의 외면을 형성해줄 거푸집(100)과, 이 거푸집(100)을 지지하는 지주(200)를 가설하고, 거푸집(100) 상에 철근을 배근한 다음 콘크리트를 타설하여 일정기간 동안 양생과정을 거치는 방법으로 슬래브(300)를 구축한다.In general, the most common method of constructing the reinforced concrete slab in the reinforced concrete structure, as shown in Figure 1, to form a form 100 to form the outer surface of the concrete, and posts supporting the formwork 100, 200 Reinforcing the rebar on the formwork (100) and then cast concrete to build a slab 300 by a curing process for a period of time.

그리고 슬래브(300)가 구축되면 거푸집(100) 및 지주(200)를 철거하고 이를 그 상부층으로 이동하여 상기와 같이 재 설치하는 방법으로 그 다음 층의 슬래브를 구축하게 된다.Then, when the slab 300 is constructed, the slab of the next layer is constructed by dismantling the formwork 100 and the support 200 and moving it to the upper layer and reinstalling it as described above.

그리고 건물의 바닥면과 슬래브 사이의 간격이 일반적인 건물보다 더 높은 복층형 구조의 슬래브 거푸집을 지지하는 방법은, 도 2에서와 같이 목재나 철재로 만들어진 지주(200)를 일반형 구조보다 더 많은 개수로 더 좁은 간격으로 설치한다.In addition, the method of supporting the slab formwork having a multi-layered structure having a higher spacing between the bottom of the building and the slab than in a general building, as shown in FIG. Install at narrow intervals.

그러나 이러한 방법과 같이 지주(200)를 이용하여 슬래브 거푸집(100)을 지지할 경우, 많은 지주(200)를 설치해야 됨으로 공사비가 증가되고 공사기간도 길어지게 되며, 하층부 슬래브가 완전히 경화될 때까지는 상층부 슬래브(300)의 콘크리트 타설이 불가능하게 되어 이에 따른 공사지연이 발생되는 문제가 있다.However, when supporting the slab formwork 100 by using the support (200) as in this way, the construction cost is increased and the construction period is lengthened by having to install a lot of support (200), until the lower slab is completely cured There is a problem in that the construction of the concrete slab of the upper slab 300 is not possible, thereby delaying construction.

본 발명은 상기한 바와 같은 종래의 문제점을 해결하기 위하여 제안된 것으로서, 본 발명의 목적은 복층형 구조로 슬래브 시공을 할 경우 양쪽 내력벽 사이에 지지되는 슬래브 거푸집을 설치하여 하층 슬래브의 경화유무에 상관없이 상층 슬래브의 콘크리트 타설을 진행시킬 수 있는 복층형 구조의 슬래브 거푸집 및 그 지지방법을 제공하는데 있다.The present invention has been proposed in order to solve the conventional problems as described above, the object of the present invention is to install a slab formwork between both bearing walls when the slab construction in a multi-layer structure, regardless of the curing of the lower slab The present invention provides a slab formwork having a multi-layered structure and a method of supporting the same, capable of advancing concrete slabs of upper slabs.

The support member 18 is fixed to the vertical bearing wall 4 by the fixing member 20 is formed on the rear side by the method of embedding the fixing part 20 when the vertical bearing wall 4 is built. Can be.

이와 같은 본 발명의 복층형 구조의 슬래브 거푸집은 건물의 바닥면과 슬래브 사이의 간격이 일반 건물보다 더 높은 복층형 구조의 슬래브를 구축할 때 유용하게 사용할 수 있는데, 이러한 본 발명의 슬래브 거푸집을 설치하려면, 먼저 수직 내력벽(4)에 설치된 지지부재(18)에 스페이서(22)를 거치 시킨 후, 이 스페이서(22)의 상부면에 트러스부재(8)를 올려놓는다.Such a slab formwork of the multi-layered structure of the present invention can be useful when constructing a slab of a multi-layered structure having a higher spacing between the floor of the building and the slab than a general building, to install the slab formwork of the present invention, First, the spacer 22 is mounted on the support member 18 installed on the vertical bearing wall 4, and then the truss member 8 is placed on the upper surface of the spacer 22.

상기 스페이서(22)는 보강재의 역할도 수행하게 되며, 이러한 스페이서(22)에 거치된 트러스부재(8)는 플레이트(10)의 끝단부에 형성된 걸림부(14)가 스페이서(22)에 걸려 트러스부재(8)는 설치된 상태를 더욱 견고하게 유지할 수 있다.The spacer 22 also serves as a reinforcing material, and the truss member 8 mounted on the spacer 22 has a catching portion 14 formed at the end of the plate 10 to be caught by the spacer 22. The member 8 can maintain the installed state more firmly.

이렇게 트러스부재(8)가 설치되면 그 상부면에 패널(6)을 올려놓으면 슬래브 거푸집의 설치가 완료되며, 패널(6)의 상부에 배력철근이나 보강철근 및 부속자재를 설치하고 콘크리트를 타설하여 일정시간의 양생과정을 거치면 슬래브(16)가 구축된다.When the truss member 8 is installed in this way, when the panel 6 is placed on the upper surface of the slab formwork, the installation of slab formwork is completed. After a certain period of curing process, the slab 16 is built.

이러한 슬래브 구축시 슬래브 거푸집은 수직 내력벽(4) 양쪽에 지지되어 있 으므로 바닥면(2)의 경화 유무에 상관없이 작업할 수 있다.When the slab is constructed, the slab formwork is supported on both sides of the vertical bearing wall (4) so that it can be worked with or without hardening of the bottom surface (2).

그리고 슬래브(16)가 구축되면, 지지부재(18)에 지지된 스페이서(22)를 일측으로 가압하여 스페이서(22)를 분리한 다음, 트러스부재(8) 및 패널(6)을 해체하여 재 사용하면 된다.When the slab 16 is constructed, the spacer 22 supported by the support member 18 is pushed to one side to separate the spacer 22, and then the truss member 8 and the panel 6 are dismantled and reused. Just do it.
