Abstract

The present invention relates to an anchor to prevent a void former from floating in a void slab which has a wire with a bottom end connected to a mold for the void slab and a top end connected to a latticed steel bar on the void former, which fixates the steel bar pressing the void former not to float during concrete casting. According to the present invention, the anchor to prevent the void former from floating in the void slab includes a hemispherical under-head unit (11) on the bottom end of the wire (10), and a cylindrical member (20) having an upper-head unit (22) inserted into the wire (10) wherein the bottom end of the cylindrical member (20) is in contact with the under-head unit (11); three cut portions (24) formed in a longitudinal direction on the cylindrical member (20); and three split pieces (26) formed on the cylindrical member (20) by the cut portions (24). If the wire (10) is pulled upwards by a coupling gun (40) while the upper-head unit (22) is caught around a hole (31) of the mold (30), the three split pieces (26) on the cylindrical member (20) are bent into a ″⊂″ shape by the under-head unit (11) formed on the bottom end of the wire (10) such that the upper-head unit (22) is pressed on the top surface of the mold (30); the three bent split pieces (26) are pressed on the bottom surface of the mold (30); and concurrently, the top end of the wire (10) is caught on an upper main bar (35) installed in the mold (30).

Description

중공 슬래브용 경량체 부상방지 앵커{ANCHOR FOR PREVENTING VOID FORMERS FROM FLOATING IN THE VOID SLAB}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an anchor for a hollow slab,

본 발명은 와이어의 하단이 중공 슬래브용 거푸집에 연결되고, 와이어의 상단이 경량체의 상부에 격자로 배치된 철근에 연결되어, 콘크리트 타설시 경량체가 부상되지 못하도록 경량체를 누르는 상기 철근을 고정하기 위한 중공 슬래브용 경량체 부상방지 앵커에 관한 것이다.
The lower end of the wire is connected to the mold for the hollow slab and the upper end of the wire is connected to the reinforcing bars arranged in a lattice on the upper part of the light weight so as to fix the reinforcing bars pressing the light weight so that the light weight is not lifted when the concrete is poured To a lightweight body floating anchor for a hollow slab.

대한민국 특허공개 제10-2009-0050259호(2009년 5월 20일, 공개)에 "중공슬래브를 위한 경량 성형재 조립체 및 이를 이용한 중공 슬래브 시공구조"가 소개되어 있다.Korean Patent Laid-Open Publication No. 10-2009-0050259 (published on May 20, 2009) discloses a lightweight molding assembly for a hollow slab and a hollow slab construction using the same.

상기 중공슬래브를 위한 경량 성형재 조립체는 철선을 교차 접합한 용접철망; 상기 용접철망 아래에 용접철망과 수직하게 접합되는 다수개의 타이볼트; 관통구멍이 형성된 경량성 단위부재로 상기 관통구멍에 타이볼트를 끼움으로써 상기 타이볼트 하단을 돌출시키면서 용접철망 아래로 설치되는 다수개의 경량 성형재; 상기 경량 성형재의 관통구멍을 돌출한 각각의 타이볼트 하단에 나사 결합되어 상기 경량 성형재를 고정하는 체결너트를 포함한다.Wherein the lightweight molding assembly for the hollow slab comprises a welded wire mesh having cross-linked steel wires; A plurality of tie bolts vertically joined to the welded wire net under the welded wire net; A plurality of lightweight molding members which are provided under the welding wire net while projecting the lower end of the tie bolt by fitting a tie bolt into the through hole with the lightweight unit member having the through hole formed therein; And a fastening nut screwed to the lower ends of the respective tie bolts protruded from the through holes of the lightweight molding material to fix the lightweight molding material.

그러나, 상기 중공슬래브를 위한 경량 성형재 조립체는 거푸집의 하부에서 거푸집 상부로 관통한 앵커볼트가 연결너트에 체결되고, 연결너트에 타이볼트의 하단이 체결되기 때문에, 앵커볼트를 거푸집의 하부에서 상부로 밀어넣기 위해 작업자 한 명이 필수적으로 거푸집 밑에서 작업할 수 밖에 없어, 안전 사고의 위험이 높으며, 앵커볼트를 끼우기 위한 구멍이 커서 거푸집을 다시 재사용할 수 없게 되는 단점이 있다.
However, in the lightweight molding assembly for the hollow slab, since the anchor bolts penetrating from the lower part of the formwork to the upper part of the formwork are fastened to the connecting nut and the lower ends of the tie bolts are fastened to the connecting nut, There is a risk that a safety accident is high and a hole for inserting an anchor bolt is large, so that the die can not be reused again.

따라서, 본 발명의 목적은 언더 헤드부가 형성된 와이어에 절개부가 형성된 원통부재가 끼워지고, 원통부재의 상부 헤드부가 거푸집의 구멍 둘레에 걸린 상태에서, 체결건에 의해 와이어가 위로 당겨지면, 와이어의 하단에 형성된 언더 헤드부에 의해 원통부재에 형성된 3개의 분할편이 "⊂" 형상으로 절곡되고, 상부 헤드부가 거푸집의 상부면이 압착되고, 동시에 절곡된 3개의 분할편이 거푸집의 하부면에 압착되고, 와이어의 상단부가 거푸집에 설치된 상부 주근에 걸리게 됨으로써, 작업자가 슬래브 성형을 위해 콘크리트를 타설하기 위한 거푸집 위에서 안전하게 혼자 앵커 고정 작업을 할 수 있고, 콘크리트가 누설되지 않을 정도로 거푸집에 천공되는 구멍이 작아 거푸집을 재사용할 수 있는 중공 슬래브용 경량체 부상방지 앵커를 제공하는 것이다.
