う。[0003] In this work, an H-shaped steel rail is placed and fixed on a pier, a slide base that moves while supporting a bridge girder is mounted on the rail, and a horizontal jack is connected to the slide base. H that supports the reaction force of the jack
This is performed using a take-over device in which a mold steel clamping device is attached to the horizontal jack. That is, the H-shaped steel clamping device in the take-up device on the H-shaped steel rails on the plurality of piers fixed in parallel at predetermined intervals is tightened so that the reaction force of the horizontal jack can be supported, and the slide is performed in this state. A bridge girder is placed over the base, and then the horizontal jack is extended to slide the slide base on the upper surface of the H-shaped steel rail, and at the stroke end of the horizontal jack, the tightening of the H-shaped steel clamping device is released. Moving the H-shaped steel clamping device connected to the horizontal jack along the H-shaped steel rail by contracting the horizontal jack,
At the end of the movement, the H-shaped steel clamping device is tightened again to support the reaction force of the horizontal jack, and the operation of extending the horizontal jack and moving the slide base is repeated to push the bridge girder to one side in the width direction of the pier. And
By performing the above operation, a plurality of bridge girder members are arranged side by side on the pier in the width direction and connected to form a bridge having a desired width. In this work, the work of moving the bridge girder in the width direction of the pier (the direction crossing the bridge at right angles) is referred to as “steal”.

等で突合わせ部分に段差が生じている。However, the H-shaped steel rails constituting the above-mentioned bridge girder moving device are not one in consideration of handling such as transportation and installation.
m-shaped steels are arranged side by side on a pier with their side ends facing each other. Moreover, the H-shaped steel rails are rarely placed directly on concrete piers, and in most cases are laid under sleepers, etc., so that the abutting surfaces of the H-shaped steel blocks are not flush. However, a step is generated in the butted portion due to sinking or the like.

に並べ軌条を構成しているのが実状である。Therefore, the slide base, which slides on the upper surface of the H-shaped steel rail, has a problem that, when the H-shaped steel rail has the above-described stepped portion, the slide base hits the stepped portion and is prevented from moving. . As a means for solving such a problem, the upper corner of the butted end of the H-shaped steel block constituting the rail is cut into a triangular shape, and a step is formed such that the slide base is caught on the butted surfaces of the H-shaped steel blocks. Although it is conceivable to eliminate the part, since most of the intercepting moving devices including this type of H-shaped steel rail are leases, if the cutting and chamfering as described above is performed, when returning the leased equipment after the completion of the construction, H The cut-chamfered part of the mold steel block must be repaired and returned to its original condition. Therefore, the rails are simply arranged in a straight line by simply butting the H-shaped steel blocks without performing any processing such as cut chamfering. This is the actual situation.

When the horizontal jack 4 reaches the stroke end, the operation of the jack 4 is stopped, and after the stopped state is confirmed, the hydraulic jack 5b of the clamping means 5 connected to the base side of the horizontal jack 4 is moved. Release and release anchorage with H-shaped steel rail 2,
After confirming the release, the horizontal jack 4 in the extended state is contracted. Due to the contraction of the horizontal jack 4, the clamping means 5 is drawn to the caterpillar type transfer table 3 along the H-shaped steel rail 2, and the hydraulic jack 5b of the clamping means 5 is actuated at the contracted end to fix and fix. Be ready to support the force. (Refer to FIG. 3 (d).) By repeating the above operation, the bridge girder B mounted on the caterpillar transfer stand 3 can be moved from one side in the width direction of the pier 1 to the other side (interception). By connecting the bridge girder members in parallel in the width direction, a bridge having a predetermined width can be formed.

することができる。In the above-mentioned take-over movement operation, even if the H-shaped steel block 2 ′ constituting the rail 2 has a step at its abutting portion as described above, the transfer table 3 that moves while supporting the bridge girder B can be moved. Since it is a caterpillar type, even if there is a step in the butted portion between the H-shaped steel blocks 2 ', the block can easily move over without difficulty, and can perform the takeover movement without fail. Moreover, since the electric hydraulic pump units 6 for operating the horizontal jacks 4 of the plurality of take-over moving devices A for mounting the bridge girders B are electrically connected, all the horizontal jacks 4 can be simultaneously operated and stopped. Can be. as a result,
Since there is no difference in the amount of movement of each caterpillar type transfer table 3 that supports and supports the bridge girder B, it is possible to safely perform the traversing movement while maintaining the bridge girder in a fixed shape. In the case of a wedge-type H steel chuck device for clamping the upper flange of an H-shaped steel rail with a wedge jack having two wedge surfaces as a clamping means, a secondary clamping force is generated by receiving a reaction force of a horizontal jack. Then, the clamped state can be reliably maintained.

うことができる。According to the first aspect of the present invention, the transfer table for mounting the bridge girder is provided on the upper surface of the rail even if there is a step formed at the butting portion of the H-shaped steel block on the rail. It can be moved over along without difficulty.
Further, according to the configuration of the second aspect, it is possible to provide a take-over moving device capable of transferring regardless of the step of the rail.
The horizontal jack and the clamping means can be collectively controlled collectively by the configuration of claim 3, and furthermore,
The horizontal jack of each moving device is operated simultaneously by the configuration of
Can be stopped. As a result, since there is no difference in the amount of movement of each caterpillar type transfer table 3 for supporting and supporting the bridge girder B,
The stealing movement can be performed safely while maintaining the bridge girder in a fixed shape.
