Description

[Detailed Description of the Invention] [Prior Art] In recent years, wiring for computers, related equipment, or communication equipment has been developed on so-called free access floors, where wiring can be freely connected no matter where the equipment is installed in the room. A double floor is used.

Conventionally, a column with a pedestal with legs and a head that can be raised and lowered by screws was erected on a floor slab, and in order to obtain earthquake resistance, the legs of the column with a pedestal were fixed to the floor slab with embedded bolts, or the legs of the column were fixed to the floor slab with embedded bolts, or the legs were fixed between the columns. A double floor is constructed by connecting the columns with horizontal bars to prevent them from falling, and placing a floor panel on the pedestal surface of this column to form a double floor.The wiring is carried out through the floor panel (floorboard), and then the wiring is routed through the opened floor panel. and connect it to the device.

[Problem that the invention seeks to solve]

In the conventional method, it is necessary to fix the columns to the floor slab with embedded bolts, or to connect the columns with horizontal bars, which increases the number of work steps. Also, in order to place the floor panel smoothly, it is necessary to incorporate screws into the support to raise and lower the pedestal.
The pillars themselves are complex and therefore expensive, and since they must be installed according to the dimensions of the floor panel, high precision is required in setting the position of the pillars (Japanese Patent Laid-Open No. 59-21380).
and Japanese Unexamined Patent Publication No. 56-3759).

Furthermore, since the floor panel is supported by pillars at the four corners, the span becomes long, which is disadvantageous in terms of strength. Furthermore, when working on wiring, etc., there is no floor panel, so it is difficult to do wiring etc.
During work, wiring etc. are easily damaged by stepping on them.

The present invention aims to eliminate these drawbacks.

[Means for solving problems]

In the present invention, a top plate (1) constituting a top plate surface and a bottom plate (2) constituting a bottom plate surface are fixed in parallel through a gap retaining material (3), and the bottom plate surface is lower than the top plate surface. This is a double floor east unit characterized by having large dimensions both vertically and horizontally, and the unit is placed on a floor slab with the bottom plate side facing down so that the edges (5) of the bottom plate sides are in contact with each other. This method of constructing a double floor is characterized by laying the floor panels (7) on top of the units.

The present invention will be explained in detail with reference to the drawings showing one embodiment of the present invention.

As shown in FIGS. 1 and 2, the east unit of the present invention includes a top plate (1) constituting a top plate surface, a bottom plate (2) constituting a bottom plate surface, and a top plate and a bottom plate. It is composed of a gap retaining material (3) that is fixed in parallel planes. The top plate surface has smaller vertical and horizontal dimensions than the bottom plate surface.

The upper board does not necessarily have to be a single board; in order to save material, multiple boards may be arranged in a slatted shape, or it may be a perforated board, a mesh board, etc. It is preferable to hold it to the extent that you can ride it.

The bottom plate can be composed of a crosspiece, and like the top plate, it can take various shapes, but it is most preferably parallelogram, preferably rectangular, and most preferably has no corners. .

The gap retaining material (3) not only holds the top plate (1) and the bottom TFFL (2) parallel to each other at the same interval, but also needs to have the strength to transmit the load from the floor panel (7) through the top plate to the bottom plate. 0 Usually, those with a groove-shaped cross section are used as cross beams, but the cross-sectional shape is! Type, C type, Z type, etc. are possible, and there is no need to specify, and it may not be a crossbeam, but may be columnar. Depending on the material, the top plate and bottom plate may be connected with adhesive, nails, or rivets. Or fixed by welding.

When constructing a double floor using the bundle unit of the present invention, as shown in Figs. They can be laid out in contact with each other without any gaps.

If the floor slab (4) is uneven, place a small piece of thin iron plate (not shown) between the bottom plate (2) and the floor slab (4) so that the upper plate surface is horizontal and the adjacent east unit Adjust so that both are smooth. By laying the sheets continuously in this way, a space (6) is formed, which can be used for wiring, piping, ventilation, etc.

At the indoor end, cut the east unit appropriately to match the dimensions. After completing the work such as wiring, lay the floor panels (7) in a staggered manner with the edges of the floor panels aligned approximately on the center line of the east unit, as shown in FIGS. 3 and 4. To take out the wiring, etc., it is sufficient to make a hole of any required size above the space (6), and the end of the room is cut to match the size.

In the present invention, a normal floor panel (7) can be used, and is made up of, for example, a structural board material (8) and a covering material (9). Needless to say, the structural board material (8) is placed on the floor. It is best to use something that can withstand the load of the equipment being installed and that can prevent the generation of static electricity. The facing material (9) satisfies the aesthetics, dustproofness, and non-slip properties of a floor finishing material, and is also antistatic, and the structural board material (8) and the facing material (9) should be in close contact with each other. It constitutes a floor panel (7). In addition, the floor panel (7) may be made of a single material, as long as it satisfies the required performance of the structural board material and the facing material, or may be in the form of a grid as a whole. do not have.

[Effect]

In the present invention, by continuously installing the east unit on the floor slab (4) with the edge (5) of the bottom plate surface touching, the space (6) for wiring etc. can be created without requiring special skills. ), and since the bundle unit has good stability, there is no need to fix it to the floor slab, and it has good earthquake resistance.

In this state, the upper plate surface of the bundle unit can be used as a work floor for wiring, etc., and even after the wiring, etc. are installed, the work can be carried out smoothly without damaging them by stepping on them or the like.

Since the space (6) runs horizontally and vertically in a plane, wiring etc. can be carried out freely.
