Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double floor used for installing wiring for a computer in an office or a floor board for this double floor.

[0002]

2. Description of the Related Art A double floor is usually composed of a support placed on a base and a floor board having corners placed on the support to form a wiring gap with the base.

This floorboard for a double floor is used during construction and transportation.
It will be in the state that many were piled up. This floorboard is usually 500
Since it is large in size of about mm mm and requires high strength, most of them are configured by stacking two iron plates with a space therebetween, and each one is heavy, weighing 5 to 10 kg. . Therefore, if the stacked floorboards are misaligned and collapsed, it is extremely dangerous for the operator and, of course, the floorboards themselves are damaged and unusable.

Conventionally, no measures have been taken against this inconvenience.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances and provides an object of the present invention to provide a measure for preventing misalignment when stacked. Also, of course, it is also possible to make it inexpensive and easy with a simple configuration,
Has an aim.

[0006]

[Means for Solving the Problems] That is, the present invention is a double-layer structure comprising a support placed on a base and a floor plate having corners placed on the support to form a wiring gap with the base. In the floorboard used for the floor, a protrusion is formed on the lower surface of the corner of the floorboard, and when the floorboard is placed on the upper surface of the floorboard such as during transportation, there is a hole that can be fitted with the protrusion of the floorboard. A floorboard for a double floor, which is characterized by being provided.

Further, according to the present invention, in a double floor composed of a support placed on a base and a floor plate having corners placed on the support to form a wiring gap with the base, A hole is provided on the upper surface, a protrusion that can be fitted into the hole of the support is formed on the lower surface of the corner of the floor plate, and the upper surface of the floor plate is
It includes a double floor characterized in that when the floor boards are piled up for transportation or the like, holes are provided so that the projections of the floor boards can be fitted therein.

[0008]

In the floor plate for a double floor according to the present invention, the projection and the hole are engaged with each other when they are piled up, so that the positional deviation is prevented.

When the support is provided with a hole, the projection of the floor plate can be used for positioning. Conventionally, in order to accurately position the floor plate with respect to the support tool, it is possible to form protrusions on the upper surface of the support tool and to provide holes at the bottom surface of the corners of the floor plate so that they engage with each other. It is being appreciated.

[0011]

The present invention will be described in detail below with reference to the illustrated embodiments.

The floor plate 10 has a substantially square shape, and two iron plates 11 and 12 are overlapped at a distance and are joined together at their peripheral portions to be integrated, and further, arcuate notches 13 are formed at respective corners.
, And step portions 14, which are lowered downward are provided. In the vicinity of the step 14 on the lower surface of the corner of the lower iron plate 11,
The projection 15 is provided by press molding. Further, a hole 16 is formed at a position above the protrusion 15 of the upper iron plate 12.

Therefore, as shown in FIGS.
5 and the hole 16 can be engaged with each other to stack the floorboard 10.

The support tool 20 comprises a pedestal 21 to which a support column 22 is rotatably mounted, and a support table 24 having a nut 23 fixed thereto is screwed into the support column 22. A groove 25 for engaging a screwdriver to rotate the column is formed at the tip of the column 22. Further, a cover 26 is provided, and the cover 26 can be attached to and detached from the tip of the support column 22 by engaging a screwdriver with a groove 27 on the upper surface and rotating the screw.
Holes 28, ... Are formed at four locations on the pedestal 24.

As shown in FIGS. 1 and 2, the support 20 is placed on a base 29 and fixed by an adhesive or the like, and the corners of the floor plates 10, ... Further, a screwdriver is engaged with the groove 25 of the column 22 and rotated, the height of the pedestal 24 is appropriately adjusted, the cover 26 is attached, and a double floor is formed. Usually, a carpet (not shown) is further placed on this and used.

At this time, the projection 15 of the floor plate engages with the hole 28 of the pedestal 24, whereby the floor plates 10, ... Can be positioned, and when the column 22 is rotated,
The rotation of the pedestal 24 can be stopped.

In the above example, the floor plate is composed of two iron plates, but it may be of any construction such as a wooden plate.

The supporting tool is not limited to the structure of the above-mentioned example, and any supporting tool having no height adjusting function may be used.

[0019]

As described above, in the double floor board of the present invention, the projections and the holes are engaged with each other when they are piled up, so that the positional deviation can be prevented from collapsing. This improves the safety of storage, transportation, etc., and prevents damage to the floorboard itself.

Since the double floor of the present invention is adapted to engage with the projection of the floor plate and the hole of the support tool, the floor board can be positioned during construction, and the support tool rotates the column. When adjusting the height by adjusting the height, the rotation of the pedestal can be stopped. Moreover, since the protrusions of the floor plate are used as they are, it is possible to replace the conventional support member with the protrusion and the hole portion of the floor plate by simply forming the hole portion in the support member, which is extremely inexpensive. It can be easily implemented.
