BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of installing / installing a floor panel with supporting bolts such as a waterproof pan on a base in an equipment unit.

[0002]

2. Description of the Related Art As a method of installing and constructing a floor panel such as a waterproof pan of an equipment unit, for example, a bathroom unit, on a base,
Conventionally, a method as shown in FIG. 5 is known.

In the method shown in FIG. 1A, an embedding nut 104 is fixed to a boss 102 formed on the lower surface side of a floor panel 100 such as a waterproof pan, and a supporting bolt 106 which is fully threaded is screwed there. The load receiving plate 1 with the nut 114 having the concave portion 112 and the head 108 at the lower end of the support bolt 106 abutting on the base 110.
The screw 16 is screwed into the support bolt 106 and screwed downward, and then grounded on the base 110, so that the load receiving plate 116 bears the support load.

In the case of this method, as shown in FIG. 1A, the lock nut 117,
After screwing the nut 114 of the load receiving plate 116, the upper end of the support bolt 106 is screwed into the embedding nut 104, and then the load receiving plate 116 is rotated to be screwed downward by height. Lock nut 1 after adjustment
17 will be tightened.

On the other hand, in the method shown in (b), a shallow dish-shaped load receiving plate 120 is set on a base 110, and the head 10 of a support bolt 118 is placed on the load receiving plate 120.
8 is placed thereon, and the weight of the floor panel 100 is supported via the load receiving plate 120.

[0006]

However, in the case of the method (a), the load receiving plate 116 is connected to the support bolt 106.
The screw must be rotated while being rotated from the upper end to the lower end, which is troublesome and troublesome. Particularly, a large number of support bolts 106 (8 to
10), there is a problem that the entire work amount becomes large. In addition, in the case of this method, it is necessary to use a high-priced, fully threaded support bolt 106, which raises the problem of increased cost.

On the other hand, in the case of the method (b), such a rotation operation of the load receiving plate 120 is not necessary,
In the case of this method, as is clear from the above description, the position of the load receiving plate 120 is specified in advance, the load receiving plate 120 is set there, and the support bolt 118 must be placed thereon. No. However, it is not easy to determine the arrangement position of the load receiving plate 120 in advance, and there is a problem in this method.

It is possible to insert the load receiving plate 120 between the head of the support bolt 118 and the base 110 once the floor panel 100 such as a waterproof pan is placed on the base 110. In this case, the work of inserting the load receiving plate 120 must be performed while the floor panel 100 is lifted, which is troublesome, and particularly, the load receiving plate 120 is inserted below the support bolt 118 at a deep place. In such a case, the operation involves a great deal of difficulty.

SUMMARY OF THE INVENTION The invention of the present application has been made to solve such a problem, and the gist of the invention is to provide a floor panel having a plurality of support bolts protruding from the back surface side.
In a floor panel construction method in which a head at a lower end of the support bolt is installed and constructed so as to be grounded on a ground via a load receiving plate, the load receiving plate may be fixed to a head of the support bolt by a predetermined locking tool. When the floor panel is placed on the ground, the load receiving plate is pressed by the force acting on the load receiving plate when the floor panel is placed on the ground. It is an object of the present invention to install and construct the floor panel in a state where each support bolt head rests on a corresponding load receiving plate while being relatively rotated.

[0010]

As described above, according to the present invention, the load receiving plate is previously rotatably locked and held on the lower surface of the head of the support bolt by the locking tool, and the floor panel is held in that state. Is placed on a substrate.

According to this method, the load receiving plate is screwed to the support bolt as in the method shown in FIG.
It is not necessary to rotate it from the upper end to the lower end, and it is not necessary to use a fully bolted support bolt.

Also, it is not necessary to determine the position of the load receiving plate in advance as in the method shown in FIG. There is no need to insert a load receiving plate between the two.

That is, according to the method of the present invention, when the floor panel is placed on the base, the load receiving plate is automatically placed between the support bolts and the base to support the weight. . This greatly simplifies floor panel construction work.

If the load receiving plate previously held on the support bolt side is fixedly provided with respect to the support bolt, when the floor panel is placed on the ground while being tilted down, for example,
There is a possibility that an excessive force acts on the load receiving plate and the load receiving plate is detached from the support bolt or deformed.

However, in the present invention, since the load receiving plate is held so as to be rotatable relative to the support bolt, such inconvenience does not occur, and the load receiving plate can be smoothly placed on the base. .

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; FIG. 2 shows a state in which a floor panel 10 such as a waterproof pan is installed. In this figure, reference numeral 10 denotes a floor panel such as a waterproof pan, from which a boss portion 12 is protruded on the lower surface side, and a support bolt 14 protrudes therefrom. Here, the support bolt 14 is screwed into an embedded nut whose upper end is embedded and fixed to the boss portion 12, and is prevented from rotating by a lock nut 16. In addition, 25 is a joist.

A load receiving plate 22 is interposed between the base 20 and the head 18 of the support bolt 14. The load receiving plate 22 has a shallow dish shape as shown in FIG.
A through hole 36 is formed in a predetermined pattern, and the elastic locking member 26 is fixed to the claw 24.

The elastic locking member 26 locks the load receiving plate 22 to the head portion 18 of the support bolt 14, and is formed by bending a metal wire. This elastic locking device 2
6 is a locked portion 28 elastically locked inside the claw 24;
It has a rising portion 30, an arm 32 seated on the upper surface of the head 18 of the support bolt 14, and a contact portion 34 elastically contacting the shaft of the support bolt 14.

FIG. 4B shows a state in which the load receiving plate 22 is locked to the head 18 of the supporting bolt 14 by the elastic locking member 26 (however, the supporting bolt 14 is indicated by an imaginary line). (Shown), the locked portion 28 is
The rising portion 30 and the arm 32 contact and sit on the side and top surfaces of the bolt head 18, respectively, and the contact portion 34 is elastically engaged with the peripheral surface of the support bolt shaft portion. In contact therewith, the load receiving plate 22 is locked to the support bolt head 18.

Here, the elastic locking member 26 is rotatable relative to the load receiving plate 22, specifically, to the claw 24 thereof. That is, as shown by the broken line in FIG.
Are locked so as to be relatively rotatable with respect to.

Next, a specific procedure of the construction method of this embodiment will be described with reference to FIG. In the method of the present embodiment, as shown in FIG.
The load receiving plate 22 is locked to the head 18 of each support bolt 14 by an elastic locking member 26. At this time, the load receiving plate 22
An adhesive 38 having a predetermined viscosity is applied to the upper surface of the substrate (see (II)).

Next, as shown in (III), the floor panel 1
This is placed on the substrate 20 while tilting 0. At this time, the lower end of the load receiving plate 22 first comes into contact with the base 20. If the load receiving plate 22 is fixedly provided to the support bolt 14, an excessive force acts on the load receiving plate 22, and the load receiving plate 22 is detached from the support bolt 14 or deformed. There is fear.

However, in the method of this embodiment, the load receiving plate 2
2 is rotatable relative to the support bolt 14, so that when a force is applied to the end of the load receiving plate 22, the load receiving plate 22 rotates relative to the support bolt 14 so as to release the force. As a result, first, the lower surface of the load receiving plate 22 is independently and entirely seated on the base 20.

The head 18 of each support bolt 14 is placed on the load receiving plate 22 only when the floor panel 10 is completely laid down. That is, each support bolt 14 comes into contact with the ground 20 via the load receiving plate 22. Here, the weight of the floor panel 10 is supported via the load receiving plates 22.

Then, the level of the floor panel 10 is adjusted by rotating the support bolts 14 and then the lock nut 1 is adjusted.
6, the support bolt 14 is stopped.

The load receiving plate 22 is nailed on the substrate 20, but even if it is difficult to nail the adhesive, the adhesive 38 escapes to the substrate 20 through the through hole 36 of the load receiving plate 22, and the load is applied. The receiving plate 22 is firmly fixed to the base 20.

The embodiment of the present invention has been described in detail above, but this is merely an example. For example, the present invention can be applied to the construction of waterproof pans and other floor panels in bathroom units and other equipment units, and the load receiving plate can be formed into various other shapes, or the load receiving plate can be formed in a configuration other than the above examples. Various modifications may be made based on the knowledge of those skilled in the art without departing from the gist of the present invention, for example, the stopper may be locked to the support bolt.
