Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double floor for forming a space for housing cables such as telephone lines and power lines on a floor of a building.

[0002]

2. Description of the Related Art Conventionally, as this type of double floor, there are known double floors having various structures depending on the height of the space under the floor. In a relatively low underfloor space, for example, on the back surface of the base on which the carpet is attached to the surface, integrally molded legs having a sufficient length to form a space when placed on the building floor, It is known that the base is spread over a building floor. For those using this base,
First, necessary wiring is performed on the building floor, and then the base is laid while avoiding wiring.

In addition, a carpet support board made of a synthetic resin, which has a groove of a predetermined width forming an underfloor space and has concrete filled inside the portion adjacent to the groove, is placed on the building floor, and a telephone is placed in the groove. It is also well known that after laying a cable such as a wire, the groove portion is closed by a steel lid and the carpet is placed on the carpet support board and the lid.

[0004]

In the former case described above, since the cables are laid before the base is laid on the building floor, the thin cables may be stepped on by the legs due to carelessness. . However, if the cable is thin, the surface height of the base is not different from the others when it is stepped on, and it is difficult to recognize that it is stepped on, and the laying work is completed in such a stepped state. If this happens, there is a possibility of cutting if the thin cable is loaded during use.

In the latter case, the difference between the materials that support the carpet when walking on the carpet between the steel lid that closes the groove and the portion that is filled with concrete. There is a slight discomfort. That is, at the location where there is concrete under the carpet,
The concrete feels like walking on a carpet laid on the building floor, while the steel lid position does not give the firm feel of concrete. . For this reason, when walking on the floor, there is a case where there is no sense of unity like that of a building floor due to the lid portion having a different feel.

An object of the present invention is to solve such a problem.

[0007]

In order to achieve the above object, the present invention takes the following measures. That is, the double floor according to the present invention is a double floor including a base that forms a storage space for articles on the floor and a floor panel that is supported by the base and forms a floor above the floor. Then, the base comprises a flexible sheet member, and a plurality of columnar protrusions having a predetermined height and integrally formed on one surface of the sheet member at predetermined intervals, and the floor panel comprises:
It is characterized in that it comprises a plurality of lid members, which are supported on the upper surfaces of the columnar protrusions and have a surface mounting member attached to the surface covering the entire upper surface of the sheet member.

In order to facilitate access to the storage space of the base, a predetermined number of lid members are supported in pairs with respect to one base, and the cover member is the predetermined number of lid members. It is preferable that the carpet is composed of one piece of carpet that is continuously attached to the surface of the.

[0009]

With this structure, a plurality of lid members are supported by the columnar projections integrally formed on the sheet member that flexes according to the shape of the floorboard, and the entire upper surface of the sheet member is covered. To do. That is, the space formed between the columnar protrusions and the upper surface of the columnar protrusions are covered with the same lid member. In this way, the space between the columnar projections and the upper surface of the columnar projections supporting the floor panel are
By being covered with the lid member, the floor surface formed by the floor panel is made of the same material, which alleviates the uncomfortable feeling when walking on the covering member.

Since a plurality of lid members are used,
When inspecting any one of the above-mentioned spaces at a desired position after construction, the inspection can be performed by opening the lid member corresponding to the space. Moreover, if a predetermined lid member is used for one base, and one carpet is attached to the predetermined number of lid members, the carpet corresponds to the base. By turning the sheet, it becomes possible to open the entire surface of the base. Therefore, the work for checking or replacing the articles stored in the space is facilitated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, a double floor F is laid on a concrete building floor, which is a floorboard, via a rubber sheet, and forms a storage space S for articles on the building floor.
A floor panel 2 supported by the base 1 and forming a floor surface above the floorboard is provided.

The base 1 is made of a synthetic resin, and has a flexible sheet member 11 and a predetermined height and is integrally formed on one surface of the sheet member 11 at predetermined intervals. Unlike 11, 11, it has a plurality of columnar protrusions 12 having rigidity that hardly deforms. Sheet member 11
Has a square planar shape and is flexible enough to be deformed in conformity with the surface shape of the building floor, and is made according to the size of the carpet 4 which is a covering member described later. There is. The sheet member 11 preferably has a side length of about 50 cm, for example. Sheet member 11
Engaging projections 13 and engaging holes 14 for connecting the sheet members 11 to each other are integrally formed near the respective corners. As shown in FIG. 3, the engagement protrusion 13 is formed so as to protrude upward at an outer position in contact with a side edge of the sheet member 11. Further, the thickness of the portion of the sheet member 11 on the base end side of the engagement protrusion 13 is made larger than other portions toward the engagement protrusion 13 so as not to tear the engagement protrusion 13. On the other hand, the engagement hole 14 is formed at a position slightly lower than the height dimension of the engagement protrusion 13 and at a position in contact with the side edge of the sheet member 11. Engagement protrusions 13 are formed on two sides extending from one corner, that is, two sides adjacent to each other across the corner, and engagement holes 14 are formed on the remaining two sides. There is.

On the other hand, the columnar protrusions 12 have a hollow columnar shape, and 9 pieces are formed in each of the sections obtained by dividing the sheet member 11 into nine equal parts. The outer diameter of the lower end of each of the columnar projections 12 is larger than the outer diameter of the upper end thereof, so that the side wall does not rise up at a right angle to the sheet member 11, but for example, about 5 ° toward the inner side of the projection from the right angle. It stands up in an inclined state. For convenience of description, in FIG. 1, a dotted line indicates a boundary of each section having a size corresponding to the lid member 3 forming the floor panel 2. That is, the columnar protrusion 12 is
They are provided upright at the four corners of one section, the center of the section (the intersection point of the diagonal lines connecting the corners of the section), and the center along each side of the section. Therefore, by arranging the columnar protrusions 12 on the sheet member 11 in this way, an open storage space in which a telephone line or the like can be laid in various directions is formed between the columnar protrusions 12, and the lid member is formed. Supports the center of 3 and the 4 corners.

The floor panel 2 placed on such a base 1 is provided with a plurality of lid members 3 supported on the upper surfaces of the columnar projections 12 and covering the entire upper surface of the sheet member 11. One lid member 3 is made of steel having a thickness of 1.2 mm, for example, and is 1/9 the size of the base 1. The periphery of the lid member 3 is bent downward at a right angle to form a side wall 31, and a notch 32 is provided at a position where each side is divided into approximately three equal parts. Then, the side wall of the notch 32 is formed by a half punch and can be easily folded and removed.
3 is attached. The cutout 32 becomes a rectangular opening (not shown) by continuing with the cutouts 32 of the lid member 3 adjacent to each other in the state where the crosspiece 33 is cut off. This opening may be used to draw out the wirings laid in the space of the base 1 above the floor panel 2. Then, a carpet 4 having substantially the same size as the base 1 is attached to the upper surface of the lid member 3.

In such a construction, the double floor F is constructed as follows. First, a rubber sheet for soundproofing is laid on the building floor where the double floor F is provided, and the base 1 is placed and fixed thereon. The base 1 engages the engaging projections 13 and the engaging holes 14 on the side edges to connect the adjacent ones. Engagement is performed by inserting the engaging projection 13 into the engaging hole 14 so that the engaging hole 14 is covered from above with the engaging projection 13 placed on the rubber sheet. . In this way, after the base 1 is laid and before the lid member 3 is placed on the base 1, the columnar protrusions 12
A telephone line, a communication cable, a power line, etc. to be stored are arranged in a storage space S between the two.

When the storage of the wirings is completed, the starting position of the wirings is determined. Then, the lid member 3 is placed on the base 1. The lid member 3 is placed corresponding to one section of the base 1, and the side wall 31 enters the gap formed between the adjacent columnar projections 12 and becomes integral with the base 1 only when placed. In this case, since the side surface of the columnar projection 12 is an inclined surface that widens downward, the lid member 3 has the side wall 3 thereof.
1 becomes a shape in which the columnar projection 12 is taperedly engaged, and the base 1
Positioning is performed simply by placing it on a predetermined position. In this way, the lid member 3 is arranged on the base 1, and the corresponding notches 32 are formed at the positions where wirings need to be raised.
The crosspiece 33 is broken off, an opening is formed by the two notches 32, and the wirings are pulled out above the lid member 3 from the formed opening. When the lid member 3 has been arranged on the base 1, the remaining opposing notches 32 not forming the opening are
It connects with the clip which is not illustrated. This clip is not always necessary, and since the side wall 31 is in the state of being taperedly engaged with the columnar projection 12, the lid member 3 can easily move in the horizontal direction even without the clip. Absent.

After the construction of the lid member 3 is completed, one carpet 4 is attached to the nine lid members 3 placed on one base 1. In other words, the carpet 4 is not attached to one of the nine lid members 3 but is attached to the nine pairs of base members 1. By attaching the carpet 4 in this manner, 1
By peeling the sheets, the entire surface of the base 1 can be opened.

As described above, since one base 1 is covered with the nine lid members 3 on the entire upper surface thereof, the completed floor surface is made of the same material regardless of which part is taken. That is, the bottom of the carpet 4 is the lid member 3 made of steel, and the columnar protrusions 12 of the base 1 are arranged on the carpet 4.
There is no part in contact with the lower surface. In addition, each lid member 3 is supported by nine columnar projections 12 in total although it is about 1/9 the size of the base 1. Therefore,
When walking on the carpet 4, the feeling of walking does not change due to the difference in the material under the carpet 4, such as feeling stiff at some parts or feeling a little soft at some parts. Therefore, it is possible to prevent the user from feeling uncomfortable when walking anywhere on the floor.

One base 1 can be regarded as an assembly of nine sections, and columnar projections 12 are formed at the four corners and the center of each section and the center of each side. Therefore, the space S for storing the wirings is large, and the wirings can be freely routed without limiting the laying direction of the wirings like the groove, and the laying work can be facilitated. Moreover,
Since one piece of carpet 4 is attached corresponding to one piece of base 1, by peeling off one piece of carpet 4,
The entire storage space S under the carpet 4 can be opened, and the maintenance and change of wirings can be easily performed.

The present invention is not limited to the embodiment described above.

In addition, the configuration of each part is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.

[0023]

As described in detail above, according to the present invention, since the plurality of columnar projections integrally formed on the sheet member at predetermined intervals support the plurality of lid members and cover the entire upper surface of the sheet member. An open storage space can be formed between the columnar protrusions, and the storage direction can be minimized when storing articles such as telephone lines. Therefore, it is possible to facilitate the work of storing such articles and reduce the work time.

Further, since the lid member is present on the entire lower surface of the cover member, the same material is used to support the cover member when walking on the cover member. It is possible to eliminate discomfort.
