[Industrial applications]

 The present invention relates to a floor material laying structure for installing various wirings on an existing floor surface.

[0002]

[Prior Art]

 In various office buildings, intelligent buildings, etc., it is necessary to lay various cables under the floor with the progress of office automation in recent years. For this reason, a new floor is newly formed on the existing floor made of concrete, and cables are laid in the gap between the existing floor and the floor.

As described above, various floor materials are sold for the purpose of forming a floor on an existing floor surface. Then, generally, a table-like floor material having four legs is arranged on the existing floor surface without any gap to form a floor.

[0004]

[Problems to be solved by the device]

 In this case, cables etc. are randomly laid between the four legs under the table-like flooring. However, in offices, etc., it is necessary to regularly inspect, repair, and change the wiring. At this time, many cables are to be peeled off from the existing floor in order to find the place to be inspected, repaired or changed, because cables and the like run under the floor. Moreover, cables are usually not laid straight, and many floor materials are crossed diagonally or the course is changed in the middle of the room. For this reason, even if one follows a cable, for example, in order to replace the cable, the floor material in the route along which the cable runs must be stripped off.

Although this alone requires a great deal of labor and time, in addition, many OA devices, desks, bookcases, etc. are placed on the floor. Then, in order to peel off the floor material, it is necessary to move these various articles one by one or take them out of the room, which is extremely complicated.

An object of the present invention is to make it possible to easily, in a short time, inspect, repair, and change wiring after laying a floor material on an existing floor surface to form a new floor.

【Example】

 FIG. 4 is a perspective view showing the flooring 2 used in the embodiment of the present invention. The flooring 2 has a table-like shape as a whole, and includes a flat plate-shaped main body 2b having a flat rectangular shape, for example, a flat square shape, and four leg portions 2c extending downward from the flat plate-shaped main body 2b. .. On the upper side of the flat plate-shaped main body 2b, a flat floor 2a having a flat rectangular shape, for example, a flat square shape is formed.

A void 2d is formed between the two leg portions 2c facing each other, and a total of four voids 2d communicate with each other below the flat plate-shaped main body 2b. An elongated plate material mounting surface 3 is formed around the floor surface 2a having a square shape in plan view so as to surround four floors of the floor surface 2a. The plate material mounting surface 3 has a square contour when viewed from above.

Then, a total of four connector attachment holes 7 are formed in the floor material 2. That is, the floor material 2 has four side surfaces, and the connecting tool mounting holes 7 are formed near the ends of the respective side surfaces. The positions of the connector attachment holes 7 should be equidistant from each other. Each connector attachment hole 7 is composed of a narrow opening 7b and a laterally wide locking hole 7a. Both the opening 7b and the locking hole 7a start from the floor surface 2a of the floor material 2 and extend toward the bottom of the floor material 2. As a result, the connector attachment hole 7 is substantially T-shaped when viewed from above, and is elongated I-shaped when viewed from the side.

FIG. 5 is a perspective view showing the plate member 1 to be combined with the floor member 2. In this plate material 1, the rectangular main body 1b is formed with protrusions 1a at both ends in the length direction, and a total of four protrusions 1a extending in the width direction of the main body 1b are formed. The positions and dimensions of these protruding portions 1a are determined by the shape and dimensions of the floor surface 2a, as will be described later. Further, a semicircular cutout 1c can be provided on the end surface of the protrusion 1a, if necessary.

FIG. 6 is a perspective view showing the connector 8 used in this embodiment. The connector 8 is designed to fit into the connector attachment hole 7 described above. Long sideways elongated rectangular parallelepiped locking portions 8a are formed at both ends of an elongated shaft 8b having a substantially rectangular cross section. The size and shape of the shaft 8b match the size and shape of the opening 7b, and the size and shape of the locking portion 8a match that of the locking hole 7a.

The floor member 2, the plate member 1, and the connecting member 8 are combined to form a floor as shown in FIGS. 1 to 3. That is, as shown in FIG. 3, the flooring materials 2 are arranged in a grid pattern so as to extend in the vertical direction and the horizontal direction in a plan view. However, for the convenience of the drawing, FIG. 1 shows only the vertical and horizontal two rows, and FIG. 3 shows only the two rows × three rows. The floor materials 2 are arranged at a predetermined distance from each other. At this stage, a grid-like gap is formed between the regularly arranged floor materials 2.

In this state, the connecting tool mounting holes 7 of the adjacent floor materials 2 face each other with a gap in between. Of course, for this purpose, the positions of the connector attachment holes 7 must be aligned in each floor 2. In this state, as specifically shown in FIG. 1, the connector 8 is lowered. However, although only two connecting tools 8 are shown in FIG. 1, it goes without saying that the connecting tools 8 are also used at other locations.

Then, the locking portion 8a is inserted into the locking hole 7a from above, and at the same time, the shaft 8b is inserted into the opening 7b. This procedure is performed at both ends of the connecting tool 8 simultaneously. At this time, if the ends of the connecting members 8 cannot be inserted into the connecting member mounting holes 7 facing each other at the same time, the floor material 2 is slightly moved to make a fine adjustment. After that, when the coupling tool 8 is released, the locking portion 8a reaches the bottom of the locking hole 7a and the shaft 8b reaches the bottom of the opening 7b. In this state, the laterally wide locking portion 8a cannot pass through the opening 7b.

By repeating this procedure, as shown in FIG. 3, the connecting members 8 are fixed in the connecting member mounting holes 7 facing each other, and the adjacent floor materials 2 are connected by the connecting members 8. As a result, although only partly shown in FIG. 3, each floor material 2 is connected to four adjacent floor materials 2 and fixed to each other. At this stage, the space between the adjacent floor materials 2 is determined. Therefore, the cable 6 and the like are laid on the existing floor surface 4 and the connecting tool 8.

Next, the plate material 1 is lowered from the state shown in FIG. 1 and placed on the plate material mounting surface 3 as shown in FIGS. 2 and 3. At this time, as described above, the plate member 1 has six projecting portions 1a, and between these six projecting portions 1a, a U-shaped concave portion 1d having a large width and a wider width than this are formed. A small L-shaped recess 1e is formed. The corners of the floor surface 2a of the floor material 2 are combined with the four recesses 1e. Half of the outer peripheral edge of the floor surface 2a of the floor material 2 is combined with the two recesses 1d. In this way, the plate material 1 is placed on the plate material mounting surface 3 of each floor material 2 while the floor surface 2a of each floor material 2 and the surface of the plate material 1 are continuous without a gap.

As a result, each plate member 1 is bridged between the six floor members 2 and supported by the floor members 2. Although only one plate material 1 is shown in FIG. 3, it goes without saying that by repeating the work of bridging the plate material 1 between the floor materials 2, the plate materials 1 are spread between the floor materials 2 without any gaps. At this time, the end faces of the protrusions 1a of the adjacent plate members 1 abut each other. A wiring passage 5 is formed below the plate member 1.

When the protrusions 1a provided with the semicircular cutouts 1c are brought into contact with each other, the two cutouts 1c are combined with each other to form a true circular hole. If necessary, the cable 6 in the wiring passage 5 is taken out from the circular hole onto the floor and connected to an electric device or the like.

According to this embodiment, the wiring passage 5 can be formed below the plate member 1, and the cable 6 and the like can be laid and laid in the wiring passage 5. With this, when the wiring is to be inspected, repaired, replaced, newly installed, or removed, the target wiring portion can be easily found by removing only the plate material 1. At this time, it is not necessary to remove the floor material 2. Moreover, the wiring of the cable 6 and the like is laid inside the wiring passage 5, and is not laid under the floor in a random manner in the vertical and horizontal directions. Therefore, if only the plate material 1 is stripped in a straight line, a certain wiring can be easily traced over the entire length, and it is not necessary to strip even an unnecessary plate material or floor material. As a result, when inspecting, repairing, replacing, or removing the wiring, it is extremely easy to find the inspection, repair, replacement, or removed portion, and these operations can be performed easily and in a short time. Even when a cable or the like is newly installed, the cable or the like may be laid by sequentially stripping the plate material 1 along the preformed wiring path 5 so as to pass the shortest distance.

Moreover, the positioning of each floor member 2 on the existing floor surface is performed by the connector 8. Therefore, even if the plate material 1 is peeled off, each floor material 2 is stably held and fixed, so that when the plate material 1 is fitted between the floor materials 2 again later, the position of the floor material 2 There is no need to readjust.

In the above example, the floor 2 and the floor 2a have a square planar shape, but may have a regular triangle, a regular hexagon, a regular octagon, a perfect circle, an ellipse, or the like. In this case, needless to say, the planar shape of the plate material 1 is also changed accordingly.

In the laying structure shown in FIGS. 1 to 3, a plate material 11 as shown in FIG. 7 can be used instead of the plate material 1. In this plate member 11, projecting portions 11a each having a planar rectangular shape project outward from four sides of a main body 11b having a planar square shape. Of the four protrusions 11a, a semicircular cutout 11c is formed on the end faces of the pair of opposing protrusions 11a. This plate material 11 is also bridged between the floor materials 2, just like the plate material 1. However, in this case, the corners of the floor material 2 are sandwiched between the adjacent protruding portions 11a, and one plate material 11 is supported by the four floor materials 2. Such a plate material 11 is easier to handle than the plate material 1, but on the other hand, the number of parts of the plate material required to form the floor is doubled.

[0024]

[Effect of the device]

 According to the present invention, since a plate material is bridged between a plurality of floor materials and a continuous surface without a gap is formed by the floor surface of the floor material and the surface of the plate material, the floor material and the floor material form a floor. Can be formed.

Since the wiring passage is formed by the plate material and the floor material, a cable or the like can be laid and laid in the wiring passage. Therefore, when you want to inspect, repair, replace, newly install, or remove wiring, you can easily find the target location by continuously stripping only the plate material, and easily trace a specific wiring over its entire length. it can. At this time, it is not necessary to peel off unnecessary plate materials and floor materials. Therefore, the inspection, repair, replacement, removal, and new work of the wiring can be performed easily and in a short time.

Moreover, one end and the other end of the elongated connecting tool are respectively fixed to the connecting tool mounting holes of the adjacent floor materials facing each other, whereby the adjacent floor materials are positioned at a predetermined interval from each other. Therefore, even if the plate material is peeled off, each floor material is stably held and fixed. Therefore, it is not necessary to readjust the position of the floor material when the plate material is fitted between the floor materials again later.
