In order to connect a plurality of FRP slab special frame as one, it is characterized by consisting of the step of assembling and reinforcing concrete on the reinforcement release reinforcing bars and placing concrete on it.

이하 본 발명의 바람직한 실시 예를 첨부된 도면을 토대로 상세하게 설명하면 다음과 같다. Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.

첨부된 도1 내지 도5는 본 발명에 따른 FRP 슬래브 특수틀을 제작하는 과정을 연속적으로 나타낸 도면이다. 이형 철근틀 제작은 길이 방향으로 하단 이형 주철근(3)과 상단 이형 주철근(2)을 격자 모양으로 절곡 이형 철근(4)으로 점 용접(Spot welding)하여 트러스를 만들어 배열하고 상단 이형 배력근(6)을 상단 이형 주철근(2)과 폭 방향으로 점 용접하여 상단 철근틀을 제작한다. 하단 이형 배력근(7)을 폭 방향으로 점 용접하여 하단 철근틀을 제작한다. 다음에는 상단 철근틀과 하단 철근틀을 슬래브의 피복을 유지하고 연결을 위하여 상, 하단 폭 방향 이형 주철근(2)과 길이 방향의 상, 하단 이형 배력근(6)이 만나는 지점에 수직 이형 철근(5)을 세워 점 용접하여 이형 철근틀을 제작한다.1 to 5 are views continuously showing the process of manufacturing the FRP slab special frame according to the present invention. Deformed reinforcing frame fabrication is made by forming a truss by spot welding the lower deformed reinforcing bar (3) and the upper deformed reinforcing bar (2) into a lattice shape in the longitudinal direction with a deformed reinforcing bar (4). ) Is spot welded to the upper mold release reinforcing bar (2) in the width direction to produce the upper rebar frame. A bottom reinforcing bar 7 is spot-welded in the width direction to produce a lower reinforcing frame. Next, the upper and lower reinforcing bars maintain the sheath of the slab, and the upper and lower reinforcing bars (2) and the upper and lower reinforcing bars (6) in the longitudinal direction meet each other in order to maintain the slab covering. 5) erect point welds to form a rebar.

다음에는 FRP 슬래브 바닥판(1)을 제조하기 위하여 철판 몰드나 FRP 몰드 위에 이형용 왁스를 도포하고 그 위에 겔코트를 도포하고 그 위에 FRP 1차 적층하고 경화되기 전 일정한 간격으로 띄워 띠 스테인레스 강판(9)을 올려놓고 그 위에 전체적으로 FRP 2차 적층하여 FRP 슬래브 바닥판(1)을 제작한다. 제작된 FRP 슬래브 바닥판(1) 위에 이형 철근틀을 올려놓고 이형 철근틀 하단 이형 주철근(3)에 일정한 간격으로 FRP 적층 고정(8)하여 FRP 슬래브 특수틀을 제작한다.Next, in order to manufacture the FRP slab bottom plate (1), a release wax is applied on an iron plate mold or an FRP mold, a gel coat is applied thereon, FRP primary lamination and floated at regular intervals before hardening. ) And put the FRP secondary laminate as a whole on it to produce the FRP slab bottom plate (1). On the manufactured FRP slab bottom plate (1) put a release reinforcing bar frame and fixed to the release reinforcing bar bottom cast iron reinforcing bar (3) FRP laminated at regular intervals (8) to produce a special FRP slab frame.
