Abstract

PURPOSE: A cable-stayed bridge type fence is provided to easily install a fence for supporting falling objects even without installation of additional bracket or truss. CONSTITUTION: A square frame is formed by combining an upper chord(14) with a lower chord(14') in perpendicular to a main support(11) at upper and lower portions between two main supports. Many screens(19) with edges(18) are fixed on the square frame. Hoisting and hanging hooks(13) are fixed in each corner and center of the square frame. A wire is connected to anchoring members installed at outside of the structure. With the structure, a fence is supported. Therefore, the fence is installed without an additional bracket or a truss. Further, interference with other construction works is minimized while cost is saved.

Description

사장교식 낙하물 방지망Cable-stayed drop screen

본 발명은 건축 공사시 발생되는 낙하물에 의한 안전사고를 방지하기 위한 낙하물 방지망에 관한 것으로, 더욱 자세하게는 비계 혹은 브라켓 등을 설치하지 않고도 구조물의 외측에 사장교식으로 설치하는 것이 가능하도록 한 낙하물 방지망에 관한 것이다.The present invention relates to a falling object prevention net for preventing safety accidents caused by falling objects generated during construction work, and more particularly, to a falling object prevention net that enables to be installed in a cable-stayed bridge outside the structure without installing a scaffold or a bracket. It is about.

건축 공사시에는 상층으로부터 떨어지는 낙하물에 의해 안전사고가 일어나는 것을 방지하기 위해 구조물의 외측에 낙하물 방지망을 반드시 설치하도록 하고 있다.During the construction work, the fall prevention net must be installed on the outside of the structure to prevent safety accidents from falling from the upper floor.

이러한 낙하물 방지망을 아파트와 같은 건축물의 외측에 설치하기 위해 종래에는 별도의 철제 브라켓 설치한 다음 일반적인 낙하물 방지망을 브라켓을 이용해 설치하거나, 이단의 브라켓을 설치한 다음 여기에 외줄 비계를 맨 후, 낙하물 방지망을 설치하였다.In order to install such a drop protection net on the outside of a building such as an apartment, a separate steel bracket is conventionally installed, and then a general drop protection net is installed using a bracket, or a two-stage bracket is installed, and then a scaffolding line is attached thereto, and then the drop protection net Was installed.

일반적으로 최근에는 건축물 공사시 비계를 설치하지 않고도 건축물 공사가 가능하도록 하는 시공방법이 적용되고 있으나, 이와 같은 종래의 낙하물 방지망을 설치하기 위해서는 전술한 바와 같이 별도의 브라켓이나 비계를 설치하여야 함으로, 공사비의 증가 및 공기가 길어지는 문제점이 있었다.In general, in recent years, a construction method that enables construction of a building without installing a scaffold in building construction has been applied. However, in order to install a conventional fall prevention network, a separate bracket or scaffolding must be installed as described above. There was a problem that the increase and the air is long.

특히, 초고층 빌딩과 같은 건축물을 시공할 경우에는 낙하물 방지망을 고층부 3층 슬라브 완료시까지 설치할 수 없는 구조이고, 고층부 3층 완료후 낙하물 방지망을 설치한다 해도 외장공사를 위해서는 최하단의 낙하물 방지망은 철거해야 됨으로써, 작업자의 안전에 심각한 문제를 야기시키는 문제점이 있었다.In particular, when constructing a building such as a high-rise building, the drop prevention net cannot be installed until completion of the three-story slab of the high-rise part. There was a problem that caused serious problems for the safety of workers.

따라서, 본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 건축물에 외측에 앙카링 철물을 선매립 혹은 선부착한 다음 현장에서 사각형태의 테두리부를 갖는 망을 사각형태의 지지파이프에 고정시켜 와이어 로프를 이용해 상기 앙카링 철물에 결합시킴으로써, 별도의 브라켓이나 비계를 설치하지 않고도 용이하게 낙하물 방지망의 설치가 가능한 사장교식 낙하물 방지망을 제공하는데 있다.Therefore, the present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to pre-embedded or pre-attached the anchoring hardware to the outside of the building and then square the net having a rectangular border at the site By fixing to a support pipe of the form to be coupled to the anchoring hardware using a wire rope, it is to provide a cable-stayed fall prevention net that can be easily installed fall prevention net without installing a separate bracket or scaffold.
