Description of the Related Art Conventionally, as a large-scale precast PC floor slab to be installed on a road bridge, a floor slab having a full width in the bridge width direction but a maximum dimension of 2 m in the bridge axial direction has been installed. Such a conventional large-scale PC floor slab has been erected using an erection device as shown in FIGS. 18 is a plan view, FIG. 19 is a front view, and FIG. 20 is a side view. This erection device mounts four traveling wheels 122, 123 on a rail 121 laid on the bridge surface, constructs a frame 124 on it, and mounts a turning device 128 on this frame 124.
The turning device 128 turns the balanced turning beam 125. Full width x bridge axial dimension 2m transported by another transport vehicle 130 equipped with self-propelled devices 131 and 132
The floor slab 94 of about a degree is suspended by the swivel beam 125, and the swivel beam swivels 180 ° in a plane and moves to the leading side. At this time, the floor slab 93 (FIGS. 19 and 20) is lowered and laid on the front side of the existing floor slab 92. For example, the PC floor slab 92 has a weight of 20 tons, and the weight of the hanging metal fitting is 6 tons. The lifting device uses a 50 ton manual hydraulic jack 129. The working radius of the turn 127 is about 6 m. Reference numeral 126 is a chain block mounting rail.

載せて橋面上を搬送する。The erection method is that the floor slabs 92 are sequentially erected from the front side, and a erection machine is placed on the slabs near the leading end of the slabs to extend and erect. This erection machine is equipped with a large-scale swing boom that lifts a floor slab 94 conveyed from the rear and swings to swing the floor slab forward. For this reason, there are restrictions on the construction of large floor slabs.
The floor slab has a full size in the width direction of, for example, 15 m or more, but the length in the bridge axial direction is divided into at most about 2 m. The transportation to the erection machine is carried on the left-right drive carriage 130 and conveyed on the bridge surface.

Place multiple trolleys in front of and behind the floor slab to be transported, hang the slabs, run all the trolleys on the bridge surface at the same speed, and set the traveling tiers of the destination trolleys at the rail step positions. Adjust the replacement, remove the rail under the floor slab at the slab laying position, install the new floor slab on the bridge surface, lay the rail on the new floor slab, change the running step of the destination trolley, all the trolleys Large-scale PC characterized by repeating the transportation and installation of the next floor slab
It is a method of erection a floor slab. In the present invention, traveling carriages are arranged before and after the floor slab to be laid. The number of traveling vehicles is usually two before and after, four in total, but a larger number may be used depending on the conditions. There is a step on the rail between the bridge surface where the floor slab is laid and the bridge surface where it is not laid. Since the forward traveling carriage needs to travel beyond this stepped portion, it is changed. The traveling carriage requires both a jack for raising and lowering the floor slab to be transported, and a jack for the carriage itself to vertically expand and contract for rearrangement, and both lifting devices.

替操作が少し異なる。Since the height of the upper surface of the rail is different depending on whether the traveling rail is on the girder or on the floor slab, it is necessary to move the forward traveling carriage up and down accordingly. Therefore, a refilling device is required. The reshuffling device is located ahead of the forward traveling carriage and is attached to the same exchanging beam as the forward traveling carriage. When the relocation device arrives at the relocation position, it sits on the rail, lifts the forward traveling carriage to take over the load of the forward traveling carriage, and then places the forward traveling carriage on the rails of different levels, and the reassembling device itself. Remove the seat from and make the other side of the bogie normal. This refilling device can be used when the level goes up or down, and works the same in both the forward and backward passes of the floor slab installation process. As the refilling device, a dolly that is exactly the same as the traveling dolly may be used, or a single jack device may be used. The refilling operation is slightly different depending on the type.
