Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a unit floor transportation device used, for example, in the erection of steel frame work for high-rise buildings.

Conventionally, in order to speed up the erection of high-rise buildings and improve safety, a unit floor-F was constructed by integrating the floor deck plate P and the small beams, as shown in Figure 1, and this was lifted up. There is a construction method that involves stacking them together and building them as one piece. In this construction method, the assembled unit floors are temporarily stored in a layered state around the ground assembly site, so a large temporary storage area is required for the unit floors, and if the site is narrow, It was not easy to secure space.

In addition, the construction of unit floors is carried out using crane trucks, but the assembled unit floors are lifted and moved from the ground assembly site to a predetermined location, so the site is narrow and the buildings are densely packed. In some cases, such as in urban areas, lifting and moving the unit floor is restricted and sometimes difficult, and it is sometimes difficult to move the crane truck.

The present invention eliminates the above-mentioned drawbacks, and one embodiment of the present invention will be described below with reference to the drawings.

2 to 4, there are a plurality of rail support members 2. made of C-shaped channel material on the ground floor 1. . . . are fixed by anchor ports 3 . . . at regular intervals. A running rail 4 is constructed above each rail support member 2, and in the illustrated example, this running rail is made of H-beam steel, and the lower portions of both flanges are welded to the rail support member 2. It is fixed. First, as shown in Fig. 5, another traveling rail 5 having the same configuration as this rail is laid parallel to the traveling rail 4, and the distance between both rails is larger than the width of the unit floor -F. One end of the narrow-6 running rails 4 and 5 extends to the unit floor assembly shop T.

In addition, there is a porta-pull winch W on the other end side of this rail.
is installed. A platform 6 for carrying the unit floor-F is movable on each of the running rails 4 and 5.

Here, the specific structure of the platform 6 will be explained based on FIGS. 2 to 4.

In this base, the side plate 7 has two upper and lower C
It is constructed by connecting shaped channels with bolts 8,
The side plates are held together by connecting members 9, 9 disposed at both ends. A plurality of rollers 10 are provided at the bottom between the side plates 7, 7.
is rotatably supported on this side plate via roller shaft loads I and 1i. The rollers 10 are movable over the upper surfaces of the webs of the running rails 4 and 5 (only the web 4a is shown). Position holding members 12 and 13, which are position holding means for the unit floor-F, are attached to the upper surface of the stand 6 in the width direction of the stand. Both position holding members 12 and 13 are made of C-shaped channel material, and rib plates 14 and 14 are used.
It is reinforced by... Position holding member 12.13
In the meantime, the unit floor-F to be set is positioned on the small beam. Note that the position holding member does not necessarily need to be made of C-shaped channel material.

Next, the operation of this device will be explained.

First, as shown in Fig. 6, two platforms 6 each are installed on the running rails 4 and 5, and then each platform 6...・Place it on top. At this time, the small beams K a on both sides of the unit floor -F
, Ka, as shown in FIG.
Set it between 13 and 13. Thereafter, another assembled unit floor is layered on the deck plate P of this unit floor F. After a certain number of unit floors F have been stacked, the wire W a (Fig. 5) wound around the porta-pull winch W is attached to the lowest unit floor, and the winch is then activated to complete the erection procedure. Taking this into consideration, the unit floor is moved to a predetermined position via the platform 6. The unit floors will then be lifted and erected one by one using a crane.

Note that instead of using a winch, the unit floor F may be pulled manually, and the means for pulling this floor is not limited to the upper side.

As explained above, according to the present invention, unit floors assembled at a sub-assembly factory can be directly stacked on the pedestal and moved to a predetermined position. Since it is not necessary to provide a storage location, it is possible to improve the space efficiency of the site. In addition, there is no need to lift the unit floor from the assembly factory using a crane and move it to the specified location, so even if the site is small,
In addition, even in densely packed buildings, the unit floor can be moved and lifted smoothly, and the crane can be fixed, so a crane truck is not necessarily required.
