Description

교량용 가설인도의 받침부재{Support material of construction sidewalk for bridge}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

본 발명은 교량용 가설인도에 관한 것으로서, 좀더 상세하게는 차량만이 통행할 수 있도록 된 교량에 있어, 교량의 폭 방향 양측에 보행자가 지나다닐 수 있도록 구축되는 가설인도의 받침부재를 개선하여 보다 빠른 시공은 물론, 시공에 따른 가설인도의 휨응력에 의한 처짐발생을 방지하여 가설인도의 안전성을 높일 수 있도록 한 교량용 가설인도의 받침부재에 관한 것이다.
The present invention relates to a temporary construction guide for a bridge, and more particularly, in a bridge that only a vehicle can pass, by improving a supporting member of a temporary guide that is constructed to allow a pedestrian to pass on both sides of the bridge in a width direction. The present invention relates to a supporting member of a temporary construction guide for a bridge that can enhance the safety of the construction guide by preventing sagging caused by bending stress of the construction guide according to construction.

주지하는 바와 같이 교량(bridge)이라 함은 물이나 어떤 곳의 위로 건너다니도록 만든 시설물을 의미하는 것으로서, 설치하고자 하는 환경이나 특성 및 용도에 따라 다양한 공법에 의해 시공된다.As is known, a bridge refers to a facility made to cross over water or a place, and is constructed by various construction methods depending on the environment, characteristics, and uses to be installed.

현재, 건설되어 사용되고 있는 교량은 다수의 교각, 상판, 교좌 및 난간 등으로 구성되며, 상기 교량은 차량의 통행뿐만 아니라, 일반 보행자의 통행을 위한 인도가 함께 설치되기도 한다. 이러한 교량에 설치되는 인도는 별도의 방법에 의행 설치되는 것이 아니라, 단순히 차량통행을 위한 차도의 가장자리, 즉 교량상판의 가장자리를 난간 등으로 구획시켜 이를 인도로 사용하고 있다.Currently, a bridge that is being constructed and used is composed of a plurality of bridges, decks, bridges and railings, the bridge is not only the traffic of the vehicle, but also the sidewalk for the passage of general pedestrians are installed together. The sidewalks installed on these bridges are not installed by a separate method, but are simply used as sidewalks by dividing the edge of the roadway for vehicle traffic, that is, the edge of the bridge deck with a railing.

특히, 차량만이 통행 가능하도록 시공된 교량에는 보행을 위한 인도를 설치하여야 하는데, 별도로 보행자를 위한 교량을 설치하는 경우 별도로 보행을 위한 교량을 다시 설치해야 하나 이는 현실적이지 못하고, 설치에 따른 과다한 비용과 비효In particular, a bridge for pedestrians should be provided with pedestrian sidewalks. If a separate pedestrian bridge is installed, the pedestrian bridge must be reinstalled separately. And ineffective

율적인 문제로 인해 현재 시행되고 있지 않은 실정이다.Due to the problem of the law, it is not currently implemented.

그렇다고 하여, 인도설치를 위해 기존에 설치된 교량에서 차도 일부분을 인도로 확보한다면 기존에 설치된 교량에서는 인도가 차지하는 면적만큼의 차도 폭이 좁아지게 되므로 차량의 원활한 소통을 방해할 뿐만 아니라, 보행자 통로의 폭이 좁아 이는 더더욱 비현실적이라 하겠다. However, if a part of the roadway is secured as a sidewalk in the existing bridge for the sidewalk installation, the roadway will be narrowed by the area occupied by the sidewalk in the existing bridge, which not only prevents the smooth communication of vehicles but also the width of the pedestrian aisle. This narrowness is even more unrealistic.

따라서 이러한 문제점을 해결하기 위해서 기존의 교량에 인도를 가설하게 된다.Therefore, in order to solve this problem, the construction of the existing bridges is made.

이러한 교량용 가설인도는 한국등록특허 제 10-0597654 호(발명의 명칭 : 차량용 교량에 설치된 인도 및 그 설치방법) 및 한국등록실용신안 제 20-0397448 호 (고안의 명칭 : 인도가 없는 교량에 가설되는 인도)가 개시된바 있으며 이는 도 1과도 2에 개시되었다.Such construction of the temporary construction for bridges is Korean Registered Patent No. 10-0597654 (Invention name: India installed on a vehicle bridge and its installation method) and Korea Utility Model Model No. 20-0397448 (Proposed name: Hypothesis on a bridge without guidance) Is disclosed in FIGS. 1 and 2.

그러나 도 1에 개시된 한국등록특허 제 10-0597654 호의 경우에는 보행자의 보호의 목적은 달성했다고 볼 수 있으나, 가설인도(100)는 교각의 상단부 일부위를 감싸는 고정체(101), 상기 고정체(101)와 프레임(103)을 연결하는 연결체(104), 프레임(103), 브라켓(104)을 시공하는 등 그 시공이 복잡하고, 시공비용이 과다하고, 시공기간이 길어 이상의 문제점을 실질적으로 극복했다고 보기 어렵다. However, in the case of Korean Patent Registration No. 10-0597654 disclosed in FIG. 1, it can be seen that the purpose of protection of pedestrians has been achieved. The construction is complicated, such as constructing the connecting body 104, the frame 103, the bracket 104 connecting the 101 and the frame 103, the construction cost is excessive, and the construction period is long. It is hard to see that you have overcome it.

또한 도 2에 개시된 한국등록실용신안 제 20-0397448 호의 가설인도(200)의 설치구조를 살피면, 브라켓(201)의 구조가 I빔(Ibeam)브라켓 보다 안정성 및 경제성이 떨어지며, 보행자 보호 난간(202)이 끼움 형식으로 되어 있어 견고함이 부족하고, 보도용 발판의 경우 평행 플레이트(203)만으로 되어 있어 장기간 사용시 휨응력에 의한 처짐이 발생할 우려가 있다.In addition, if you look at the installation structure of the provisional guide 200 of the Korean Utility Model Registration No. 20-0397448 disclosed in Figure 2, the structure of the bracket 201 is less stable and economical than the I beam bracket, pedestrian protective railing (202) ), It is in the form of fitting, and lacks in firmness, and in the case of the sidewalk scaffolding, there is only a parallel plate 203, which may cause sagging due to bending stress when used for a long time.

따라서 보행자를 위한 인도의 설치에 있어, 시공자로서 경제적인 부담과, 교량의 안정성 및 시공의 어려움이 여전히 존재하고 있으며 또한 보행자 보호의 근본적인 문제점이 여전히 남아 있다.
Therefore, in the installation of sidewalks for pedestrians, the economic burden as a contractor, the stability of the bridge and the difficulty of construction still exist, and the fundamental problems of pedestrian protection remain.

본 발명은 상기와 같이 제반되는 종래의 문제점을 해결하기 위하여 발명한 것으로, 차량만이 통행할 수 있도록 된 교량에 있어, 교량의 폭 방향 양측에 보행자가 지나다닐 수 있도록 구축되는 가설인도를 개선하여 보다 빠른 시공은 물론, 시공에 따른 가설인도의 휨응력에 의한 처짐발생을 방지하여 가설인도의 안전성을 높일 수 있는 교량용 가설인도 받침부재를 제공하는데 그 목적이 있다.
