感じていた。As described above, a jack is used to push up a bridge. However, if the capacity of the jack is increased, the weight of the jack increases and handling becomes impossible by hand, and the capacity of the jack is reduced. Increasing the number increases the number of workers and makes it difficult to tune a large number of jacks due to the accuracy of the jacks. In the case of a hydraulic jack or a mechanical jack, if a long-stroke jack is used, heavy objects can be lifted at once, but the jack may not fall because the jack cannot be fixed due to its structure. . For this reason, if a short-stroke jack is used, the risk of falling of the jack is small, but more sandals are required. And since it is work under the overpass, it is possible to raise heavy objects to a certain height with a truck crane, but more than that, it will be manual work, and when jacking the bridge girder, it will be work at a high place , Very dangerous. In addition, when sliding the bridge girder, it is necessary to install a vent facility under the bridge girder and for moving the bridge girder, which requires more member weight and requires more work at high places, which increases the risk of workers. Become. In particular, since the up and slide work of a long bridge is extensive, communication between workers becomes insufficient, which causes more danger. There were many problems in this way, and I felt very inconvenient in construction.

Lifting means consisting of a lifter that can be moved up and down with a screw jack, support of a lifting means that supports assembly and disassembly, and a vent that is provided on the outer periphery of the lifting means to support with the lifting means. Means and means are arbitrarily combined to form a pair, and several pairs are provided at appropriate places in series under the bridge corresponding to the weight of the bridge to be removed or newly constructed, and both ends of the stroke of the lifting means are encoder and limit. It is a dual safety device for the switch, and when the lifting means moves up and down, it can be monitored by the stroke position indicator for each lifting means, and load cells are attached to all lifters of the lifting means provided in series. The load applied to each lifter can always be checked in the operation room, and when an abnormal load or critical overload is applied, a signal from the current relay is used. Even if there is a normal stop, all of the control electrical devices and sensors (encoders, cables, sequencers, etc.) will stop immediately, and even if there is an accident such as a power outage or cable disconnection, the internal battery will back up the memory. In addition, it has various protection functions such as reverse phase, open phase, overload, etc., all control signal transmission is digital communication cable system, so that troubles on cable connection are eliminated, lifting means, support means, By controlling the lifting means by operating the lifting means and the supporting means by means of a control means capable of synchronizing the moving means by centralized control, the bridge can be installed while installing objects (vents) by the supporting means under the lifting means and the supporting means. The whole body is made the same by moving means that pushes up and moves the tension body such as steel rods and jacks in synchronization with the control means while the bridge is supported by the lifting means and the supporting means. Lateral moved to, placing a bridge on removal or piers than on piers. When the removal or placement (new installation) is completed in this way, the installation work (vents) by the support means is removed from the lower side, which is the opposite of the lifting work, by the operation of the lifting means, and all the work is completed. It was done like this.

FIG. 27 shows a state in which the external vent 41 and the lifter vent 21 are provided in two stages, respectively, and the old bridge 60 is lifted from above the pillar 64. When the old bridge 60 is lifted up, the lifter 1 is moved up and down again to provide the mounting base 55b together with the mounting body 55a at the center of the lower surfaces of the receiving beams 52 and 59, and the sliding bodies 53 at both ends, and the Teflon plate on the rail supporting member 63. The traverse rod 54 is attached to the mounting body 55a and is connected to the tension body 56 of the slide device 51 for each series, and an error always occurs from the control box (not shown in the drawing) at the same time as shown in FIGS. 28 and 27. The four stations are pulled together and are slid to a predetermined position shown in FIG. When the movement of the old bridge 60 is completed in this way, the lifter vent 2
1 and external vent 41 are removed from the lower stage
After placing the old bridge 60 on top and making it in the state shown in FIG. 30,
All of the material is removed from the rail receiving material 63, the old bridge 60 is dismantled on the spot, and the work of removing the old bridge 60 is completed.

を有し産業利用上非常に優れた発明である。As described above, according to the present invention, the vents of the supporting means are always inserted at the lowest stage to push up the bridge.
By reducing work at high altitudes and synchronizing many lifting and moving means with centralized control,
Even in a wide range of work, it is possible to securely and securely perform communication while keeping close contact, so that in addition to reducing the number of workers, it is possible to reduce the danger of workers and increase safety. Also, by using the lifting means with a screw jack, it is possible to lift for a long stroke, and at the same time the bridge is moved by the lifting means and the supporting means while the bridge is being supported. This is a very excellent invention for industrial use because it has many features such as the number of vents is only under the elevated part of the bridge and it is economical without requiring many members.

Then, the bridge is pushed up while the supporting means is provided below the lifting means and the supporting means by the operation of the lifting means, and the tension body that depends on the steel rod or jack while the bridge is supported by the lifting means and the supporting means. When the bridge is removed from the bridge pier or placed on the bridge pier and the removal or placement (new installation) is completed With the operation of lifting means Bridge removal installation construction method being characterized in that so as to remove the support means from below into.
