To install, a plurality of vertical members 23 are installed in the lower part of the girder 13, and the lower members of the vertical member 23 are also interconnected with the vertical lower connector 22 while interconnecting the vertical members 23 with the bracing 21. Since the installation of the upper bridge support 20 is possible only through a very complicated assembly process, the work process is very cumbersome, and the manpower and time required for the work are also required for a long time, resulting in an increase in the cost of the bridge installation work. This has been raised.
본 발명은 상기와 같은 문제점을 개선하기 위하여 제안된 것으로서, 사전에 제작된 교량거더지지브라켓을 교각 및 교대의 교좌장치 위에 설치하고, 그 위에 바로 거더를 거치하도록 하여 교량을 설치하는 교량의 상부구조물을 지지하면서 작용하중을 교좌장치로 적절히 전달하는 기능을 하는 교량거더지지브라켓을 번거롭지 않게 사전에 제작하되, 구조가 간단하면서 내부가 통공부가 형성된 강재의 4각통체로 지지대를 제작하여 구조적으로도 강한 지지기능을 발휘하도록 하는 교량거더지지브라켓을 이용한 교량시공방법인 것이다.The present invention has been proposed to improve the above problems, the bridge girder support bracket prepared in advance on the bridge and the bridge of the alternating device, the upper structure of the bridge to install the bridge to mount the girder directly thereon The bridge girder support bracket, which functions to properly transfer the working load to the bridge device, is produced without any hassle in advance. It is a bridge construction method using the bridge girder support bracket to exert the supporting function.
상기 교량거더지지브라켓(30)을 이용하여 교량(10)을 설치하는 시공방법은 교량(10)을 설치하기 위하여 양측부에는 교대를 설치하고 내측으로는 일정한 간격 으로 교각을 설치하면서 교좌장치(15)를 각각 설치하고, 상기 설치된 교대와 교각, 교각과 교각의 상부에 설치된 교좌장치(15) 위에 교좌안착부(33)가 설치되도록 하면서 교량거더지지브라켓(30)을 설치하되 상기 교량거더지지브라켓(30)의 네방향 또는 2방향으로 형성된 지지대(31)가 상향으로 거치되도록 한 다음, 거더(13)를 한쌍의 지지대(31) 위에 각각 일체연결설치하는 작업을 하면서 교량거더지지브라켓(30) 위에 거더(13)를 설치하고, 거더 위에 교량상판슬래브(12)를 설치하기 위한 철근을 배근한 다음, 콘크리트를 타설양생하여 교량상부구조물을 설치한 다음 양측에 연석(11)을 설치하여 교량(10)을 시공하는 것이다.The construction method for installing the bridge 10 by using the bridge girder support bracket 30 is installed on both sides to install the bridge 10, while installing the bridge at regular intervals inside the bridge device (15). ), Respectively, the bridge girder support bracket 30 is installed while the seat seating portion 33 is installed on the bridge device 15 installed in the upper portion of the bridge and the bridge, the bridge and the bridge, the bridge girder support bracket The support 31 formed in four or two directions of the 30 is mounted upwardly, and then the girder 13 is integrally installed and installed on the pair of supports 31, respectively. Install the girder 13 on the top, reinforce the reinforcing bar for installing the bridge slab 12 on the girder, and then cast concrete to install the bridge upper structure, and then install the curb 11 on both sides of the bridge ( 10) It is construction.
상기 교량거더지지브라켓(30)은 중앙에 일정한 크기의 교좌안착부(33)가 형성되고 상기 교좌안착부(33)의 네방향에 일정한 길이로서 중앙은 통공부(34)가 형성된 4각통체(32)의 지지대(31)가 형성되도록 하되 교좌안착부(33)가 있는 내측으로 오므라든 4각피라밋모서리형태를 갖는 강재로 제작한 것이거나,The bridge girder support bracket 30 is formed in the center of the seat seating portion 33 of a constant size and a constant length in the four directions of the seat seating portion 33 as the center of the quadrilateral body formed with a through hole 34 ( 32) is formed of a steel material having a four-sided pyramid corner shape, such that the support 31 is formed, but is retracted inward with the seat seat 33,
또는, 가운데가 일정한 크기의 교좌안착부(33)가 형성되고, 상기 교좌안착부(33)의 양측에 일정한 길이로서 중앙은 통공부(34)가 형성된 4각통체(32)의 지지대(31)가 형성되도록 하되 교좌안착부(33)가 있는 내측으로 오므라진 V자형태인 강재로 제작한 것이다.Alternatively, the support seat 31 of the quadrangular body 32 is formed in the center seating portion 33 having a constant size, a constant length on both sides of the seating portion 33, the center portion is formed with a through-hole 34 To be formed, but the seat seating portion 33 is made of steel that is V-shaped retracted inward.
종래에는 교좌장치 위에 거더를 지지하기 위하여 강재를 브레이싱으로 상호연결한 지지체를 제작하여 교각 위에 설치하므로서 교량설치시 지지체의 제작과 설치에 많은 시간과 인력이 소요되므로 설치가 매우 번거롭고, 또한 설치비용이 과다하게 소요되는 단점이 있는 것이다.Conventionally, in order to support a girder on a bridge device, a steel plate is interconnected by bracing and installed on a bridge, so that a lot of time and manpower is required to manufacture and install a support when installing a bridge. There is a drawback in overuse.
이와 같이 종전에 사용하던 브레이싱의 사용을 생략하면서, 구조적으로 강도가 우수하며 단위중량이 가벼운 4각통체를 이용하여 4방향 또는 2방향의 지지대가 형성되도록 교량거더지지브라켓을 제작하여 이를 교각의 교좌장치 위에 설치만 하고, 그 위에 거더와 지지대가 일체로 연결되도록 설치하면 교량설치가 간단히 완료되도록 하였다. In this way, the bridge girder bridge is made by forming a bridge girder support bracket to form a support in four directions or two directions by using a four-cylindrical cylinder with excellent structural strength and light weight while omitting the use of the conventional bracing. Only installation on the device, and the girder and the support on the unit to be connected integrally, the bridge installation was simply completed.
상기와 같이 기제작된 교량거더지지브라켓을 교각 위에 설치만 하면되며, 또한 내부가 빈 4각통체로 제작되어 총중량이 가벼워 설치가 용이하게 하므로서 교량설치기간이 단축되며 설치비용도 절감되도록 하는 것에 본 발명의 주안점이 있는 것이다. The bridge girder support bracket manufactured as described above only need to be installed on the pier, and also the inside is made of a hollow cylinder, so that the total weight is light, so that the installation is easy and the installation period of the bridge is shortened and the installation cost is also reduced. The main point is that.
