Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a floor panel of one type, which is a basic type, from which wires such as power lines and communication lines having different thicknesses can be taken out. . Further, the present invention provides a double floor structure in which the entire floor surface is made nonflammable by making the floor panel nonflammable and making the base member on which the floor panel is mounted nonflammable. Another object of the present invention is to provide a double floor structure capable of coping with irregularities on the floor surface.

[0002]

2. Description of the Related Art Conventionally, in order to take out power lines and communication lines from a floor panel, holes of various sizes have been formed in the floor panel. In the case of a thin line, the take-out hole must have a size suitable for the thin line, and in the case of a thick line, a hole having a thickness corresponding to the size needs to be prepared in advance. In order to cope with such a situation, one kind of floor panel is provided with a hole having a thickness likely to be variously necessary, or several types of floor panels are prepared according to the thickness of the hole. Further, as a base plate on which the floor panel is mounted, a flammable synthetic resin integrally molded product has been used.

[0003]

As described above, in order to take out a line such as a power line or a communication line from below the floor panel, it is necessary to form a wiring hole in the floor panel in advance. The position, number, size, etc., of the holes were assumed, so that they could be accommodated. In particular, it is reasonable to keep the number of extraction holes to the minimum necessary.However, there are several types of line thickness, and if holes with different thicknesses of extraction holes are prepared in advance according to the line thickness. When it comes to
There were several different sized holes in one floor panel, and thus the number of holes was also increasing. To avoid this, separate floor panels may be prepared depending on the thickness of the line, but that is uneconomical,
There was a problem that the construction was complicated.

Further, since the base plate on which the floor panel is mounted is made of a synthetic resin alone, it is flammable and is not preferable for laying on a floor in a building. Further, since the synthetic resin product is a hollow molded product, it is lightweight, has no sense of stability, and has a poor walking feeling. Furthermore, forming the base plate with a synthetic resin requires a large number of manufacturing steps, such as a step of manufacturing a sheet member, a step of manufacturing columnar projections, and a step of combining them, which is expensive in terms of cost. Therefore, a hardening material such as mortar is used for the columnar projections, and a hole is formed in the sheet member for bonding the sheet member and the mortar, and the mortar is poured into the hole. The mortar or the like protrudes, and the lower surface side of the sheet member swells, causing irregularities. Further, in order to avoid the above-mentioned unevenness, the lower surfaces of the mortar and the like and the sheet member are flush with each other. In this case, however, the columnar projections are easy to come off, and a separate fixing means such as use of an adhesive has been adopted. Also,
When the columnar projection is a cylindrical projection with a bottom made of a synthetic resin, it is conceivable to pour mortar or the like into the space. However, as in the above case, there is a possibility that the mortar may fall out of the projection, and thus use of an adhesive is required.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks. In the present invention, one kind of floor panel having cutouts of the same size is provided. By providing a floor panel, the size of a hole formed by a cutout between adjacent floor panels can be changed, and power lines and communication lines having different thicknesses can be taken out on the floor panel.

FIG. 8 is a plan view of the base plate 8, and the size of the base plate 8 is large enough to be used. The base plates 8 are connected to other base plates 8 by appropriately forming connecting means on the peripheral edge of the base plates 8. Columnar projection 1
Numeral 0 denotes a columnar shape having a substantially quadrangular prism shape. The sheet member 9 is divided into nine sections, and is formed so as to project from each corner thereof. An appropriate number of slits are formed between the sections or between the adjacent columnar projections 10 along the boundary, and the slits make the corresponding portions flexible hinge portions H.
It is made. Therefore, even if the floor surface is uneven, the hinge portion H and the thin steel plate can cope with the uneven surface of the floor surface. Each columnar projection 10 has a lower end dimension larger than the upper end dimension, and has a tapered side peripheral surface. Due to the configuration of the base plate 8, the space between the columnar projections 10 is formed as a wiring storage space S for various wirings such as a power line and a communication line. The floor panel 1 described above is placed on the base plate 8 as shown in a side view of FIG. One floor panel 1 is placed on one of the nine divisions described above, and the bent side wall portion 3 of each floor panel 1 is adjacent to the column-shaped projection 10 at the peripheral edge and inside thereof. The top plate 2 of the floor panel 1 is placed on the upper surface of the columnar projections 10 by bridging the columnar projections 10 such as between the columnar projections 10 or between the adjacent inner columnar projections 10. As a result, the entire surface of the base plate 8 is covered with several floor panels 1.

Embodiment 4 An embodiment of a method of manufacturing the base plate 8 will be described below. As the sheet member 9, a member made of a flexible thin steel plate or the like is used. On the other hand, the columnar projections 10 are cylindrical or solid, and are made of mortar, epoxy resin-containing mortar, or the like. The sheet member 9 and the columnar projection 10 need to be integrally formed, and a member having a sense of stability is required. Further, a non-combustible material is required. The column member 10 is attached to the sheet member 9 at a predetermined interval so as to fit the bent side wall portion 3 of the floor panel 1. In order to improve the connection between the sheet member 9 and the column member 10. Then, as shown in FIGS. 10 to 13, the sheet member 9 at the position where the columnar protrusion 10 is provided is formed with protrusions 11, 11 'or uneven portions 12, or a combination of the above protrusions and uneven portions. . Protrusions 11, 11 ', uneven portions 12, etc.
By forming 3, the connection state between the sheet member 9 and the columnar projections 10 can be strengthened.

Embodiment 5 A manufacturing method for forming columnar projections 10 on a steel sheet member 9 will be described below. As shown in FIG. 10, projections 11 are formed on the sheet member 9 made of steel sheet in correspondence with the positions where the columnar projections 10 are located. The projection 11 has an appropriate number of holes 13 formed therein. A mold 14 is arranged so as to surround the protrusion 11. The formwork 14 can be formed on the frame 15 so as to correspond to the size of the entire base plate 8 as shown in FIG. It is also possible to make the frame larger. After setting the mold 14 on the sheet member 9 made of steel plate, a hardening material such as mortar with zero slump or extremely few slumps is poured into the gap of the mold 14. For immediate demolding, a slump 0 is adopted. In addition, mortar mixed with epoxy resin may be employed. Although the mold may be cured by natural drying or the like and then released, the slump 0 may be cured by surrounding the cured material with the mold frame 14 and the pressing member from above, and applying vibration to the entire steel sheet member 9. It is possible to immediately obtain the dense columnar projections 10 without the occurrence of jumpers and the like.
In such a case, after the mold 14 is removed, curing is performed, and a hardening material such as mortar is solidified, whereby the base plate can be completed. The mortar or the like flows downward through the holes 13 of the protrusions 11, and the protrusions 11 enter the mortar and are integrated. Therefore, the columnar projections 10 do not fall off the sheet member 9. In addition, since the lower surface of the sheet member 9 and the lower surface of the mortar can be flush with each other by disposing a mold or the like, the base plate itself does not become uneven.

Embodiment 6 In the above embodiment, after setting the mold 14 on the sheet member 9 made of steel sheet, a hardening material such as mortar is poured into the gap. In this embodiment, as shown in FIG. And formwork 1
After setting 4, a hardening material such as mortar is poured into the gap of the formwork 14, and the sheet member 9 made of steel is
The protrusion 11 is pushed so as to be located in the hardening material. Thereafter, the mortar or the like wraps around from the holes 13 of the projections 11 by applying pressure and applying vibration, and the columnar projections 10 in which the projections 11 enter the mortar can be obtained.
Then, by removing the formwork 14 and performing curing,
Complete the base plate.

In the case of slump 0 or the like, the mold can be immediately removed as described above. After the mortar or the like is cured, the mold 14 can be removed. Since the lower part of the columnar projection 10 is large and the side surface is formed in a tapered shape, the mold 14 can be smoothly removed from the mold. By the above-mentioned production, the sheet member 9 made of steel sheet and the mortar or the like that becomes the columnar projections 10 are firmly connected. FIG. 12 shows another embodiment of the projection 11 ′, in which a sheet material 9 made of steel plate corresponding to the position where the columnar projection 10 is located is pushed upward, and a hardening material such as mortar is formed by bending the edge thereof. And means for improving the adhesion strength of the adhesive. As shown in FIG. 13, the sheet member 9 made of the steel sheet with the uneven portions 12 formed thereon can also integrate the sheet member 9 made of the steel sheet and the columnar projection 10 in the same manner as described above. The protrusions 11 'and the irregularities 12
Properly providing holes in the sheet member is effective as a strong connecting means between the steel sheet member 9 and the columnar projections 10. Therefore,
Since the columnar projections 10 do not come off from the sheet member 9 and the lower surface of the sheet member 9 and the lower surface of the mortar or the like can be flush with each other by disposing the formwork or the like, the base plate itself becomes uneven. There is no. The projections 11 and 11 'and the uneven portion 12 may be provided at the same time.

Embodiment 7 A construction method of a floor panel according to the present invention will be described below.
The base plate 8 is laid on the building floor from the center to the periphery of the room with or without a nonflammable and elastic cushioning material or the like. The base plates 8 are connected to each other by an appropriate engaging means formed on the peripheral edge.
After that, in the wiring storage space S formed on the base plate 8,
Necessary power lines, communication lines, etc. will be provided. When the storage of the wiring is completed, the starting position of the wiring is determined,
While checking the size of the wiring hole of the floor panel 1 according to the position, the floor panel 1 is made to correspond to one section of the base plate 8.
Is placed.

Since the columnar projections 10 of the base plate 8 are formed in a tapered shape having a large bottom side, the columnar projections 10 of the floor panel 1 are engaged with the bent side wall portions 3 so as to spread, so that the columnar projections 10 are placed between the columnar projections 10. The floor panel 1 is positioned just by placing it. The arrangement of the floor panel 1 determines the positions of the notches 5 facing each other according to the thickness of the line to be taken out. When taking out a thin line, the cutouts 5 are opposed so that the tops thereof are shifted. When taking out a thick line, the tops of the cutouts 5 are made to face each other so as to coincide. The wirings are drawn out onto the floor panel 1 from the opening formed as described above.

[0021]

As described in detail above, according to the present invention,
The floor panel 1 is made of a steel plate, and the periphery thereof is bent to a substantially right-angled shape on the back side, so that the entire floor panel 1 is provided with nonflammability and rigidity. Further, a notch 5 is formed in each peripheral portion 4 of the floor panel 1, and the notch 5 has a notch shape in which cut depths from both base ends thereof are different, so that the adjacent floor panel is formed. 1
By simply changing the arrangement position of the above, without separately preparing floor panels having cutouts of different sizes, the opening is formed large at the position where the vertices of the cutouts 5 face each other. As a result, a thick line can be pulled out from the lower part of the floor panel.

On the other hand, the opening for drawing a thin line is arranged so that the vertices of the notches facing each other are shifted, so that the size of the opening is reduced, so that the opening that fits the thin line is formed. It becomes possible to 1
It has become possible to select the size of the hole rationally with different types of floor panels 1. The base plate 8 used as a base material of the floor panel 1 includes a steel sheet member 9 and a columnar projection 1.
0 is firmly connected by the projections 11 and 11 ′, the concave and convex portions 12, the holes 13, and the like. Unlike the conventional hollow member made of synthetic resin alone, a predetermined mass is obtained, and As a result, it is possible to obtain a member having a strong and stable feeling. Therefore, a member excellent in walking feeling can be obtained. Further, a flexible hinge portion H is formed between one section of the steel sheet member 9 and the sheet member 9 made of a thin steel plate can cope with unevenness even if the building floor has irregularities. It was possible to lay down. Furthermore,
The floor panel 1 is placed on the base plate 8. Even if the base plate 8 is slightly moved up and down due to the unevenness of the floor surface as described above, the unevenness is prevented by the base plate 6. Since the floor panel 1 is only absorbed and fitted between the columnar projections 10 of the base plate 8, the floor panel 1 can be laid without being affected by the unevenness.
