DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support leg which is attached to a floor panel applied to a floor structure such as a double floor structure on a roof and supports the floor panel.

[0002]

2. Description of the Related Art In a flat concrete roof of a building such as a building, drainage facilities are provided, of course. In addition to this, a waterproof sheet is provided to prevent rainwater from penetrating into the concrete itself. Water leakage prevention structures stretched inside are common. However, this structure has the disadvantage that once the concrete is put on it with the waterproof sheet, it is impossible to perform maintenance such as investigating the cause of water leakage that occurred afterwards or inspecting the condition of the waterproof sheet. Has been shunned, and instead, lay a tarpaulin on the installation floor,
A double floor structure in which a large number of fixed floor panels are arranged thereon has been adopted.

In this structure, a waterproof sheet is laid on an installation floor formed by casting concrete, and a large number of floor panels formed in a rectangular shape such as a square are laid side by side on the waterproof sheet. It is designed to be able to easily turn over and expose the waterproof sheet or the concrete installation floor thereunder. In this case, a support leg is provided on the floor panel, and the floor panel is laid on the installation floor via the support leg. That is, a floor panel is not laid directly on the waterproof sheet, but a gap is formed between the waterproof sheet and the supporting leg by interposing the supporting legs, thereby improving drainage and heat insulation. Conventionally, the above-mentioned support legs have a rod-like shape, and are attached to the four corners of the lower surface of the floor panel by uneven fitting, and the grounding surface at the bottom is spread in a disk shape so as to be stably laid. The general shape is.

[0004]

The floor panel laid on the installation floor via the support legs is designed to be laid without gaps, and even if gaps occur due to dimensional errors, surface conditions, or deviations, such gaps are not removed. Since it was slight, there was a problem in drainage. In addition to the lack of gaps, the support legs do not connect adjacent floor panels, so if a strong wind blows over the floor panels, there will be a difference in air pressure in the space above and below the floor panels. As a result, a phenomenon occurs in which lift occurs on the floor panels, and the floor panels are individually lifted up or, in some cases, turned up apart. There is no problem if the installation floor is a very smooth horizontal surface, but if it is so-called uneven with slight irregularities or is slightly inclined as a whole, the effect of such installation floor conditions Directly
There was a drawback that floor panels could not be laid horizontally.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a floor which exhibits a good drainage property, prevents a floor panel from being lifted or turned up, and can maintain a stable laid state for a long period of time. It is intended to provide support legs for the panel.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and the supporting legs of the floor panel according to the first aspect are mounted so as to match the four corners of the lower surface of the floor panel.

According to a third aspect of the present invention, in the floor panel support leg according to the first aspect, the support plate extends along the pair of end surfaces forming the corners of the floor panel so as to abut on the pair of end faces. It is characterized in that claw pieces sandwiched between the end faces of the floor panel are formed.

According to a fourth aspect of the present invention, in the support leg of the floor panel according to the first aspect, the support leg is screw-connected to at least one of the pressure receiving table and the bracket. It is characterized in that a bolt member that makes the overall height variable is interposed.

[0010]

According to the supporting leg of the floor panel according to the first aspect of the present invention, the adjacent floor panels are connected to each other via the connecting mechanism of the bracket which is mounted at the four corners of the lower surface of the floor panel. As a result, even if it receives a strong wind, the resistance to the lift is greatly increased, so that the lifting and the turning up are prevented. The connecting mechanism is provided on the backing plate portion of the bracket and connected to the bracket adjacent to the bracket in a straight line with each other, and is inserted across the continuous connecting holes. With the connecting pins, the floor panels can be connected with each other without any trouble in the laying work, with a simple structure at a low cost.

According to a third aspect of the present invention, a claw sandwiched between end surfaces of adjacent floor panels extends by abutting against a contact portion of the bracket along a pair of end surfaces forming a corner of the floor panel. If a piece is formed, a gap is reliably formed between the floor panels, and good drainage is exhibited.In addition, the upper and lower spaces of the floor panel communicate with each other due to the gap, and the pressure difference between the upper and lower spaces is reduced. It is less likely to occur, and the generation of lift of the floor panel is suppressed, thereby further preventing the floor panel from lifting or turning up.

According to a fourth aspect of the present invention, a bolt member is provided between the pressure receiving table and the bracket, which is screwed to at least one of them to make the height of the entire support leg variable. Even if the installation floor has irregularities due to unevenness, the height of the support legs is adjusted according to the amount of screwing of the bolt member to the pressure receiving table or bracket, and the floor panel is responded to the unevenness of the installation floor. Can be arranged horizontally.

The pressure receiving table 50 is fixed to the bolt 30 to complete the assembly. The height of the support leg 1 can be arbitrarily adjusted by the screwing amount of the pressure receiving table 50, and the height is fixed by the stopper 40.

After the support legs 1 are attached to the four corners of the floor panel 2 as described above, the waterproof sheet S is laid on the installation floor on which the floor panel 2 is laid, and the waterproof sheet S is placed on the outside of the installation floor. From the support legs 1. At that time,
A connecting pin 20 is previously inserted into a supporting leg 1 attached to one floor panel 2 of adjacent floor panels 2, and the connecting pin 20 is connected to the supporting leg 1 attached to the other floor panel 2.

The mating floor panels 2 are connected.

Thus, the connecting pin 20 is connected to the connecting hole 18.
The floor panels 2 can be connected to each other by a simple operation such as insertion into the floor panel. This operation has the advantage that the work of laying the floor panels 2 is not troublesome and the connecting mechanism can be manufactured at low cost. By making the height of the support legs 1 constant, the support legs 1 can be arranged horizontally with respect to the installation floor. Adjust so that they line up horizontally. Thus, the floor panel 2 is connected to the support legs 1.

Since the adjacent nail pieces 19 are overlapped and sandwiched between the end faces 5 of the floor panel 2, a gap 60 is definitely formed between the end faces 5, so that the rainwater falling on the floor panel 2 From 60, the drainage is smoothly drained onto the waterproof sheet, and rainwater does not accumulate on the floor panel 2, and a good drainage property is exhibited.

Further, since the gap 60 ensures communication between the space above and below the floor panel 2, the difference in air pressure between the space above and below the floor panel 2 even when a strong wind blows over the floor panel 2. It is unlikely to occur. In addition, the connecting pins 20 connect the supporting legs 1 in a state where the upward movement is particularly restricted. Since the gaps 60 are formed between the floor panels 2 and the floor panels 2 are connected to each other by the connecting pins 20 as described above, even when a strong wind blows on the floor panels 2, no lift is generated and the floor panels 2 are not lifted. The phenomenon in which the floor panels 2 are individually lifted or turned up does not occur, and the stable laying state of the floor panel 2 is maintained for a long time.

Even when the installation floor is uneven due to unevenness, if the height of the support leg 1 is adjusted according to the screwing amount of the pressure receiving table 50 into the bolt 30, the floor can be adjusted in accordance with the unevenness of the installation floor. The panels 2 can be arranged horizontally. further,
Since the pressure receiving plate 53 of the pressure receiving table 50 is spread in a disk shape, the surface pressure on the installation floor is low, and the waterproof sheet S and the like are not easily damaged.
