Description of the Related Art There is a technique of using a steel girder as an erection device when a precast concrete bridge girder is erected for each span on a pier to construct a bridge. In this technology, a steel girder for erection is advanced from the abutment on one end side of the bridge to bridge the girder on the abutment and pier, and a traveling crane that carries the precast concrete bridge girder is mounted on the girder and the bridge girder is overlaid. Will be transported in the direction of the bridge axis and a precast concrete bridge girder will be installed in the span. Then,
Using this bridge girder, the girder is advanced to the next span to build the bridge girder on the next span. As described above, the bridge girder erection device composed of such steel girders moves forward on the bridge girder constructed after the completion of the bridge girder construction for one span to construct the bridge span girder for the next span, and successively advances. Bridge girders with multiple spans will be installed. Such steel girders use a pair of left and right girders, and a portal crane with both legs mounted on the left and right girders.The portal crane suspends the space between the pair of left and right girders by suspending a precast concrete bridge girder. Carry in the direction.

な隣接する橋脚が不平行な場合、その径間に横に並べて
架設される多数の橋桁はそれぞれ長さが不均等になる。By the way, the bridge piers are not always provided at right angles to the bridge axis, and the piers located at both ends of one span are not necessarily parallel to each other. There are cases in which construction will be carried out in a non-parallel manner due to restrictions due to factors such as restrictions due to rivers and tides. When such adjacent bridge piers are not parallel to each other, a large number of bridge girders horizontally arranged side by side between the piers have uneven lengths.

工期も増加する問題があった。In the conventional construction of a bridge girder using a pair of steel girders, when adjacent piers are not parallel to each other, when the supporting portion on the pier of the girder protrudes from the pier, an auxiliary pier extending obliquely is provided on the pier. Make sure that the trolley is on top of it,
I had no choice but to lay the girder on this trolley. In such an erection method, unless the bridge pier is parallel to the bridge axis at a right angle, a temporary auxiliary bridge pier must be constructed, which increases construction labor, required materials, and construction costs.
There was a problem that the construction period also increased.

で、安全面の問題もあった。Further, in a bridge girder erection device using a steel girder, a hand girder is attached to the tip of the steel girder, and the tip of the girder is placed on the next pier to advance the girder. When the girders are sequentially advanced in this manner, a support for receiving the tip of the hand-held girder is provided on the other side of the bridge pier, and the load of the girder is balanced so that the bridge girder erection device can be transferred to the other side. Can be done easily. The hand girder horizontally extends from the tip of the steel girder and is located at a high position above the top of the pier.Therefore, the temporary post for the delivery roller, which has a high height to receive the end of the hand girder, is previously transported on the other pier. It is necessary to assemble it in advance. At this time, since the girder cannot be used for the work on the other side of the pier, a separate carrying device, an unloading crane, etc. are required, and the work is enormous. This work is required for every pier every time the erection equipment is advanced. Furthermore, the temporary columns for the delivery rollers are unstable because of their high length, and when placing the end of the hand girder, great care must be taken and there is a safety problem.

The girder made by himself got in the way, and I couldn't erection with the gate crane on the girder.
Therefore, it was necessary to bring the girder closer to the center side, install a suspension device different from the normal girder suspension device, and lift and erect the ear spar with the girder on one side. When adjacent girders are not parallel and the length of the girders that are parallel to each other changes, it was necessary to change the device each time the girder on one side was moved to the center.

必要としない。The operation of the bridge girder erection device of the present invention is as follows. (1) In the conventional method, in order to allow the girder to traverse in spans where adjacent piers are not at right angles to the bridge axis, an auxiliary pier must be provided to arrange the traverse device that supports the girder at right angles to the bridge axis. However, even when the adjacent piers cannot be formed at right angles to the bridge axis in the device of the present invention, the traverse device can be obliquely provided on the pier and the girder can traverse over the traverse device. This is because the support part behind the girder is mounted on the traverse trolley via the forward and backward rollers, so that each of the left and right steel girders can traverse at the same time while advancing or retracting in the bridge axis direction, and the entire erection device is This is because the parallelogram 4-link mechanism can be moved. Therefore, even when the adjacent bridge piers have non-parallel spans and bridge girders with spans with different lengths are not installed, the traverse device on the piers can be installed parallel to the pier girder bearing line. Therefore, extra support work (auxiliary bridge piers) for the traverse device is not required. (2) In the installation of the ear girder, in the conventional method, a girder length is changed because a girder on one side is installed with a suspension device different from the normal girder suspension device and the girder is erected and erected with one girder on one side. In that case, it is necessary to change the device combination each time,
In the bridge girder erection device of the present invention, since the normal girder suspension device on the girder can be used for erection of the ear girder, another girder suspension device for the ear girder is unnecessary, and the bridge girders arranged in parallel with one span are not required. It is possible to easily deal with a change in the digit length of. (3) Since the girder is mounted on each traverse trolley in a state that it can be rotated horizontally in the front and rear, and the left and right steel girders are connected by horizontal joints of pin hinges, the installation angle of the girder is erected. Even if it changes within the span, the installation can be performed correspondingly. (4) By adopting a hand girder that can be moved up and down, it is possible to use a small trolley that moves above the hand girder to increase the height without the need to pre-assemble a high-strength provisional roller support post on the pier. A low and light pedestal can be easily postponed and installed on the pier, which allows the hand girder to be supported on the pier. Therefore, in the conventional method, it is no longer necessary to construct a temporary post for the sending roller on the forward pier, which was required in advance when the erection equipment was advanced, reducing labor and construction period, and improving the safety level when advancing the erection equipment. Contribute. (5) Since the outrigger jacks are provided on both sides of the front traverse trolley mounting part and the rollers with jacks are provided on the rear traverse trolley, when moving the equipment to the next span, hydraulic jacks other than the equipment and Does not require heavy equipment such as truck cranes.
