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 construction of high-rise buildings and improve safety, a unit floor F, which is an integrated floor deck plate P and small beams K, was assembled on the ground and lifted up as shown in Figure 1. There is a construction method in which it is constructed as one piece. In this construction method, the assembled unit floors are temporarily stored in a layered state around the sub-assembly site, so a large temporary storage area is required for the unit floors, and if the site is narrow, it may be difficult to secure space. It wasn't easy.
In addition, a crane truck is used to lift the unit, but the assembled unit floor is lifted and moved from the ground assembly site to the specified location, making the site narrow and the buildings densely packed. In urban areas, lifting and movement of the unit floor is restricted and sometimes difficult, and there are times when it is not easy to move the crane truck. In addition, it has been used as a transportation trolley since the 1970s.
- The one described in Publication No. 20043 has been proposed. This trolley is for transporting corrugated asbestos slate roofs. Two axles are installed in parallel on the underside of the bogie frame, which is the slate support frame. At both ends of each axle, there are wheels that roll on rails on the main roof surface. are provided for each. However, using such a trolley for transporting unit floors has the following problems. That is, the object to be transported is a unit floor made of steel, and each of these unit floors is, for example, about 12,200 mm long and 600 mm wide, and is large and heavy. For this reason, if conventional carts were used as they were, the carts would be extremely large, and would not be able to withstand the load of stacking unit floors for transportation.Furthermore, unit floors are not flat, and the bottom surface is Because of the shape with small beams, a problem arises in that smooth loading and transportation are not possible.

An object of the invention is to increase the space efficiency of the site, another object is to facilitate the movement and lifting of unit floors even in narrow sites, and still another object is to improve the space efficiency of the site without increasing the size. The purpose is to withstand the load of the unit floor and enable smooth loading and transport.

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

In Figs. 2 to 4, a plurality of rails made of C-shaped channel material are placed on the ground floor 1 by support members 2,

It is fixed by A running rail 4 is installed above each rail support member 2, and in the illustrated example, the lower part of both flanges is fixed to the rail support member 2 by welding using H-shaped steel. be. Then, as shown in FIG. 5, the traveling rail 4
Along this rail, another traveling rail 5 having the same configuration as this rail is laid in parallel, and the interval between both rails is narrower than the width of the unit floor F. Traveling rail 4
and one end of 5 is the unit floor assembly factory T
It extends to Note that a portable winch W is installed on the other end side of this rail. 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 platform, the side plates 7 are constructed by connecting two C-shaped channels, upper and lower, with bolts 8 in this example, and are held between the side plates by connecting members 9, 9 disposed at both ends. A plurality of rollers 10 are arranged in a row at predetermined intervals in the lower part between the side plates 7, 7.
It is rotatably supported via 1 and 11. The rollers 10 can freely roll on the upper surfaces of the webs (only the web 4a is shown) of the running rails 4 and 5. By arranging a large number of rollers 10 in succession, each roller shares the load and the platform runs smoothly. Position holding members 12 and 13, which serve as position holding means for the unit floor F, are attached to the upper surface of the base 6 in the width direction of the base. The position holding members 12 and 13 are both made of C-shaped channel material and reinforced with rib plates 14, 14, . . . . The position holding members 12 and 13 position the beam K of the unit floor F set between them. 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 sets of two platforms 6 each are installed on the running rails 4 and 5, and then,
The unit floor F assembled at the subassembly factory is placed on each platform 6. At this time, the small beams Ka, Ka on both sides of the unit floor F are set between the position holding members 12, 13 as shown in FIG. Thereafter, other assembled unit floors are sequentially stacked on the deck plate P of this unit floor F. When a certain number of unit floors F are stacked, the portable winch W
Attach the wire Wa (Fig. 5) wound around the base to the lowest unit floor, and then operate the winch and move the unit floor to the specified position via the base section 6, taking into account the erection procedure. Move up to. The unit floors will then be lifted one by one using a crane and erected. When 20 unit floors P are loaded on the platform 6, the load applied to each roller 10 is 600 kg.

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 above example. Further, the crane may be fixed, and a crane truck is not necessarily required.

As explained above, according to the present invention, unit floors assembled at a subassembly factory can be directly stacked on a platform and moved to a predetermined position, so it is not necessary to use a large temporary storage space for unit floors as in the past. Since it is not necessary to set up a device, the space efficiency of the site can be improved. In addition, there is no need to use a crane to lift the unit floor from the subassembly factory and move it to the specified location, so even if the site is small or the buildings are crowded, it is easy to move and lift the unit floor. Weight can be applied smoothly. In addition, the unit floor is supported by at least two sets, one set each running on each running rail, and a large number of rollers are arranged at the bottom so that each roller shares the load. It is not large in size, can withstand large loads, and can be loaded and transported smoothly. Furthermore, since the lowermost unit floor functions as a base plate that supports the upper unit floor, the configuration of the device can be simplified.
