Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a floor panel in which a foamed concrete surface plate is laminated on an upper surface of a base material.

[0002]

2. Description of the Related Art Conventionally, in order to construct a floor panel 3 in which a surface plate made of foam concrete is laminated on the upper surface side of a base material, a nylon sling 60 is wound around the floor panel as shown in FIG. Lifted by a crane, beamed, hauled,
It was placed and fixed on the floor structure such as joists.

[0003]

In the above conventional example, an operation of winding a nylon sling 60 around the floor panel 3 (that is, an operation of passing the sling 60 under the floor panel 3) is required. In addition, it is necessary to remove the sling 60 after placing the floor panel 3 on the floor structure, and it is troublesome and time-consuming due to heavy labor, and the floor panel 3 may be misplaced. Since the panel 3 must be lifted and the sling 60 must be hooked, the workability is poor, and there is a risk that the floor panel 3 may slip off from the sling 60, which poses a safety problem. Further, when the sling 60 is wound around the floor panel 3 and is suspended by a crane, the sling strongly hits the corners of the end portion of the surface plate of the floor panel 3 shown in FIG. There is a problem that breakage of the corners occurs. Especially the floor panel 3
If the surface plate is made of foam concrete, there is a problem that it is easily damaged.

An object of the present invention is to solve the above-mentioned problems of the conventional example, and when lifting and installing a floor panel,
You can easily and safely lift and install floor panels,
It is an object of the present invention to provide a method of constructing a floor panel that can be constructed without damaging a surface plate.

[0005]

In order to solve the problems of the above-mentioned conventional examples and to achieve the object of the present invention, the floor panel construction method of the present invention is made of foam concrete on the upper surface side of the base material 1. The floor panel 3 having the surface plate 2 laminated thereon is lifted one by one with the side end faces of the opposite sides of the base material 1 being sandwiched by the clamp device 4, and sequentially placed and fixed on the floor structure 50. It is what In this way, by lifting the side end faces of the opposite sides of the base material 1 while being clamped by the clamp device 4, the surface plate 2 made of foam concrete
Is prevented from being damaged by the clamp device 4, and the floor panel 3 can be easily and surely lifted by the clamping by the clamp device 4.

[0006] Here, it is preferable that the side end surface of the base material 1 is projected outward from the side end surface of the surface plate 2. In this way, when the side end surface of the base material 1 is projected outward from the side end surface of the surface plate 2, when the side end surfaces of the opposite sides of the base material 1 are clamped by the clamp device 4, the surface plate 2 of the surface plate 2 is clamped. The clamp device 4 does not accidentally hit the side end surface, and the damage of the surface plate 2 can be reliably prevented.
