[0002]

2. Description of the Related Art Conventionally, a floor panel 3 in which a surface plate made of foamed concrete is laminated on the upper surface side of a base material is constructed as shown in FIG.
As shown in FIG. 8, a nylon sling 60 is wound around a floor panel, lifted by a crane, and placed and fixed on a floor structure such as a beam, a pulling bar or a joist.

[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 suspended by a crane, the sling strongly hits the corner of the end of the surface plate of the floor panel 3 shown in FIG. There is a problem in that the corners are damaged. In particular, when the surface plate of the floor panel 3 is made of foamed concrete, there is a problem that the floor panel 3 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 prior art and achieve the object of the present invention, the floor panel construction method of the present invention uses a foam concrete The surface plate 2 is laminated and the side end surface of the base material 1 is set to the upper surface.

And the floor panel 3, lifting the side end surface of the opposite sides of the base material 1 one by one in a state of being sandwiched by the clamping device 4, the floor
It is characterized in that it is placed and fixed on a structure sequentially. In this manner, the surface plate 2 made of foamed concrete is prevented from being damaged by the clamp device 4 by lifting the side end surfaces of the opposing sides of the base material 1 while being clamped by the clamp device 4. it by clamping by the device 4, which can lift the floor panel 3 easily and reliably, that is the case, protrudes the side end surface of the base material 1 to the outer side than the side end surface of the surface plate 2
When the side end surface of the base material 1 is made to protrude outward from the side end surface of the surface plate 2, the side end surface of the facing plate 2 is clamped by the clamping device 4 when the side end surface of the opposite side of the base material 1 is clamped. Therefore, it is possible to surely prevent the damage of the surface plate 2 without the clamping device 4 being accidentally hit by the clamp device 4.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. 5 and 6 show a floor panel 3 according to the present invention. The floor panel 3 is configured by laminating a surface plate 2 made of foamed concrete on the upper surface side of a base material 1. The base material 1 has a base plate 6 such as a particle board or a plywood fixed to an upper surface side of a wooden joist material 5 juxtaposed with a wooden space with a fixing tool such as a screw nail, and a gypsum board such as a gypsum board between the joist materials 5. A sound insulating material 7 is provided, and the sound insulating material 7 is
Is fixed to and supported by a reinforcing material 8 such as a particle board or a plywood, which is fixed to a lower surface side of the device by a fixing tool such as a screw nail. A floor plate 3 made of foamed concrete is superimposed on the upper surface of the base material 1 having the above-described configuration (that is, the upper surface of the base plate 6) and fixed with a fixing tool such as a screw.
Is configured. Here, the side edge of the base material 1 of the floor panel 3
As shown in FIG. 5 and FIG.
It is configured to protrude.

FIGS. 3 and 4 show a clamp device 4 used for lifting the floor panel 3 having the above-described configuration for construction. The clamp device 4 has the following configuration. That is, a pair of opposed frame bodies 9 are connected by a connection frame 10 to form a main frame 11,
Near the center of the frame body 9, substantially intermediate portions of a pair of intermediate links 12 each having a U shape are rotatably mounted by shafts 13. One end of a holding link 14 is rotatably attached to the lower end of each intermediate link 12 by a shaft 15, and a holding piece 16 is provided at the other end of the holding link 14 downward. An anti-slip member 17 made of rubber or the like is provided on the inner surface of the member 16. In addition, link 1 for pinching
A lower end of a link 18 is rotatably mounted near a protruding base portion of the holding piece 16 of FIG.
Is rotatably mounted by a shaft 20 near the front end of the frame body 9. An upper link 21 is rotatably attached to each upper end of the pair of intermediate links 12 by a shaft 22, and an upper end of each upper link 21 is rotatably attached to an upper frame body 23 by a shaft 24. Here, the opposing upper frames 23 are connected by a connection frame 25. One end of a stopper member 26 is rotatably attached to one of the shafts 22 that are supported by the intermediate link 12 and the upper link 21, and the other shaft 22 is connected to the stopper member 26. Is inserted through a long hole 27 provided in the hole. One end of the long hole 27 is provided with a stopper groove 28 communicating with the long hole 27 at a substantially right angle. A pair of stopper members 2
6 near the end where the stopper groove 28 is provided.
Are connected by A stopper removing member 33 which can freely contact the connecting rod 32 is attached to the connecting frame 10, and a contact member 29 is attached to the connecting frame 10 downward. The portion is provided with a cushioning member 30 such as rubber. A hook 31 provided on the lower end of the wire 45 is hooked on the hanging member 31 so that the clamp device 4 can be lifted by a crane.

[0008] The lifting and construction of the floor panel 3 having the foamed concrete surface plate 2 laminated on the upper surface side of the base material 1 is performed as follows. That is, as shown in FIG. 3 , with the shaft 22 positioned in the stopper groove 28, the clamp device 4 is lifted by a crane and positioned on the floor panel 3, and is lowered in this state to lower the buffer member of the contact member 29. 30 abuts on the surface plate 2 of the floor panel 3. In this state, when the wire suspending the clamp device 4 is further loosened, the upper frame 23 moves downward, and accordingly the stopper member 26 moves downward, and the stopper removing member 33 hits the connecting rod 32, and As a result, the stopper member 26 is raised, whereby the shaft 22 is positioned at the end of the elongated hole 27 from the stopper groove 28, and the stopper state is released. In removing the shaft 22 from the stopper groove 28, an operator may use a hand or a jig to move and remove the stopper member 26. After the stopper is removed in this manner, when the upper frame 23 is lifted by a crane, the upper frame 23 moves upward, and the upper link 21 is pulled up accordingly.
And the distance between the two shafts 22 is shortened. As a result, the intermediate link 12 rotates about the shaft 13 to move the holding link 14, and as shown in FIGS. Link 1
4 sandwiches the side end surfaces of the opposing sides of the base material 1 of the floor panel 3 with the holding pieces 16 of the floor panel 3. Lift the floor panels 3 one by one in the sandwiched state,
The floor panels 3 are sequentially placed on a floor structure such as a beam, a pulling bar and the like, and the floor panel 3 is fixed to the floor structure with screws or the like.

Here, in the present invention, when the floor panel 3 is clamped and lifted by the clamp device 4, the side end faces of the opposite sides of the base material 1 of the floor panel 3 are sandwiched so that the surface plate 2 is sandwiched. Is characterized in that the side end face portion is not damaged by the load applied during lifting. This
In the case of, the side end face of the base material 1 of the floor panel 3 is
Because it is configured to protrude outward from the end face,
At the time of clamping, the holding piece 16 of the clamping device 4
It is reliably prevented from hitting the side end face,
When hanging it more clamped,
Damage will be prevented. In the embodiment shown in FIG. 1, the clamping pieces 16 are clamped so that the lower ends of the opposing clamping pieces 16 are narrower than the upper ends thereof when clamping.
Is slightly inclined inward, and by inwardly inclined in this way, only the side end surface of the base material 1 located at the lower portion of the floor panel 3 when sandwiched by the sandwiching pieces 16 is ensured.
The holding plate 16 is held so strongly that the side end surface of the surface plate 2 located above the floor panel 3 does not come into contact with the holding pieces 16, so that no force is applied to the side end surface portion of the surface plate 2 during lifting. Further, the damage of the side end face portion 2 is further prevented. In addition, since the non-slip member 17 such as rubber is provided on the inner surface of the holding piece 16, the side end surface of the base material 1 can be securely and firmly held when the holding piece 16 is held by the holding piece 16. Become.

[0010] Note that as the clamping device 4 for use in the present invention FIG. 3, not limited to those shown in FIG. 4, may be as shown in FIG. In the one shown in FIG. 7 , the upper portions of two clamp members 40 bent in a stepwise manner are rotatably attached by shafts 41, and the lower ends of upper link members 43 are rotated by shafts 42 on the upper ends of both clamp members 40 respectively. The upper link members 43 may be freely mounted, the upper ends of the upper link members 43 may be rotatably mounted on the shafts 44, and the shafts 44 may be suspended by wires 45. In this state, the base material 1 of the floor panel 3 is opposed by the holding piece 47 at the lower end of the clamp material 40 in a state where the lateral contact portion 46 of the clamp material 40 bent in a stepwise manner is applied to the upper surface of the floor panel 3. The side end faces of the sides are lifted one by one while being clamped by the clamp device 4 so as to be sequentially placed and fixed on the floor structure .

The clamp device 4 is not limited to the structures of the above-described embodiments as long as the clamp device 4 can clamp the side end surface of the opposite side of the base material 1 of the floor panel 3. Of course.

[0012]

In the present invention, as described above, the laminated Then the foam concrete surface plate on the upper surface of the base material
Both side end surfaces of the surface plate with the side end surface of the base material laminated on the upper surface side
The floor panels protruding outward from the base material are lifted one by one in a state where the side end faces of the opposing sides of the base material are clamped by the clamp device, and sequentially placed and fixed on the floor structure, so that Unlike the conventional example in which the sling is wound and hung, the work of winding the sling around the floor panel is not required, and it is possible to easily and securely clamp and lift the sling without any labor, and to easily release the sling. And can perform a safe operation with good workability in a short time. Moreover, a surface plate is laminated on the upper surface side of the base material.
However, since clamping by the clamp device clamps the side edges of the opposing sides of the base material, no force is applied directly when clamping and lifting the side edges of the easily breakable foam concrete surface plate. It can prevent the face plate from being damaged. In particular, since the side end surface of the base material protrudes outward from the side end surface of the surface plate, the surface plate made of foam concrete, which is easily damaged at the time of clamping by the clamping device, is not clamped, and a force is applied when clamping and lifting. In addition to being able to prevent damage to the surface panel, it is possible to prevent the floor panel from being applied and to prevent the adjacent floor panel or positioning jig at the time of construction from hitting the easily breakable foam concrete surface plate. It is.
