[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of laying a plurality of or a large number of ground reinforcing iron plates on an outdoor work site or a construction site.

[0002]

2. Description of the Related Art In an outdoor work place or a construction site, a heavy machine is used to lift heavy equipment so that heavy equipment or a vehicle for transporting materials and equipment can easily pass or can be placed on an uneven ground. A plurality of iron plates, that is, ground reinforcing iron plates, or a large number of iron plates are laid. The ground reinforcing iron plates are connected to each other so that the function as a passage can be sufficiently exerted, or the function as a material / material storage place can be sufficiently exerted, and they are laid so as not to shift.

As a method of connecting such ground reinforcing iron plates to each other, it has been customary in the past to use welding with a reinforcing metal. Further, as disclosed in Japanese Utility Model Laid-Open No. 6-35505, a method has been proposed in which a hole is formed in a ground reinforcing iron plate and the ground reinforcing iron plate is stopped by a connecting pin in a glaze shape.

[0004]

However, the welding stopping method requires welding work, which is troublesome at the time of laying it and also takes time at the time of removal, so that when the number of ground reinforcing iron plates is large, the ground reinforcing iron plates are laid. However, there was a problem in that it would cost a lot of money. In addition, the method of using the connecting pin has a problem that it takes time and labor because it requires the work of making a hole in the iron plate. Also, in this method, it is necessary to move the iron plates to adjust the position in order to insert the connecting pin into the hole, but the ground reinforcing iron plate is usually handled by a lifting machine at about 1600 kg, and the weight is large, so this position adjustment is required. This is a difficult task, and there is also a problem that it is not possible to efficiently connect the ground reinforcing steel plates to each other. The present invention has been devised in view of the above circumstances, and an object of the present invention is to provide a method and a connecting tool capable of efficiently connecting ground reinforcing iron plates to each other without increasing costs.

[0005]

In order to achieve the above object, the invention according to claim 1 is a method of laying ground reinforcing iron plates, wherein a plurality of ground reinforcing iron plates having a rectangular shape in plan view are hoisted by a lifting machine and adjacent to each other. Then, when arranging in a plane on the ground, it consists of two engaging members that are swingably connected, and each engaging member is opened to the swing end side to allow the ground reinforcing iron plate to be inserted. Prepare a plurality of connecting tools in which a recess is formed, and engage one side of the first ground reinforcing iron plate laid on the ground with the recess of one engaging member of the connecting tool,
When laying on the ground the second ground reinforcing iron plate arranged adjacent to the first ground reinforcing iron plate, the other engaging member of the connecting tool is tilted so that the recess faces upward, The second ground reinforcing iron plate is lifted so that its surface extends in the up-down direction, and in this state, the second ground reinforcing iron plate is hung and one side located below the second ground reinforcing iron plate is used as the recess of the other engaging member. It is characterized in that the second ground reinforcing iron plate is laid on the ground while being engaged with the second ground reinforcing iron plate about the swing center of the engaging member. According to a second aspect of the present invention, there is provided a connecting tool used when the ground reinforcing iron plates are connected to each other on the ground and arranged in a plane, and the two engaging members of the connecting tool can swing. Each engaging member is formed with a concave portion that is opened at the swinging end side thereof and that allows the ground reinforcing iron plate to be inserted therein.

[0006]

[Function] First, one ground reinforcing iron plate is laid on the ground,
The concave portion of one engaging member of the connecting tool is inserted into the side of the ground reinforcing iron plate, one engaging member is engaged, and the other engaging member is swung so that the concave portion faces upward. Next, the second ground reinforcing iron plate is hung down, the side of the ground reinforcing iron plate is inserted into the recess of the other engaging member, and the ground reinforcing iron plate is engaged around the swing center of the engaging member. Swing together with the member and lay on the ground. In this way, many ground reinforcing iron plates are laid one after another. When removing the ground reinforcing iron plates, the ground reinforcing iron plates located at the ends of the ground reinforcing iron plates arranged in a plane are sequentially lifted. When hoisting the ground-reinforcing iron plate, swing the side where the connecting tool is not attached upward about the swing center of the engaging member, and set the orientation such that the ground-reinforcing iron plate extends vertically. If the ground reinforcement iron plate is lifted as it is,
The side of the ground reinforcing iron plate is disengaged from the recess of the engaging member. In this way, the ground reinforcing iron plates located at the ends are sequentially removed.
