Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for forming a double floor structure for accommodating cables for electricity and communication in an underfloor space and is laid for treating a floor end portion adjacent to a wall surface. Border material for double floors.

[0002]

2. Description of the Related Art In a double-floor structure such as an office building, support blocks are arranged at predetermined intervals on a slab base, floor panels are laid on the support blocks, and cables such as electric and communication cables are laid under the floor. A space can be secured.

Since such a floor panel is manufactured with a certain size (for example, length 165 mm × width 165 mm × thickness 20 mm), it is inevitable that when the floor panel is laid on a slab base, the end face of the floor panel and the wall surface are Or, a gap (hereinafter, referred to as “excess space”) is generated in the adjacent portion to the area around the pillar.

Therefore, at the construction site, a floor block is cut and processed according to the surplus space by newly disposing a support block in the surplus space or fixing a joist material to the wall surface. Laying out and floor end treatment.

However, in such a construction method, it takes a lot of time to cut the floor panel, and the number of additional support blocks increases, resulting in an increase in cost. In addition, when a load is applied to the end material of the floor panel, the supporting area is small, so the supporting load per unit area becomes large, exceeding the allowable strength of the floor panel, and the floor surface (refers to the floor surface formed by the floor panel. () Cannot be made uniform in rigidity.

In order to solve these problems, a double-floor border material for filling an extra space around the floor panel has been proposed (Japanese Patent Laid-Open No. 4-93459).

As shown in FIG. 11, in this double-floor border material 90, one end of a border panel portion 92 is supported by the support block 14 on which the floor panel 16 is placed, and the other end is integrally molded. The legs 94 are grounded on the slab base 20. As a result, the border panel portion 92 is made flush with the floor panel 16, and the rigidity of the floor surface can be made uniform.

Therefore, the floor end portion of the surplus space can be processed only by installing the double-floor border material 90 obtained by cutting the border panel portion 92 according to the surplus space.

[0009] By the way, with the OA of offices, a large amount of cables for electricity and communication arranged in the underfloor space 26 are introduced into the wall surface 96, or the cables arranged in the wall surface 96 are installed in the underfloor space. 26 may be introduced. In this case, in the conventional double-floor border material 90, when introducing the cable from the underfloor space 26 into the wall surface 96, it is necessary to cut the support leg 94 at the opening for passing the cable at the construction site.

However, if such an opening is cut at the construction site, the number of working steps increases, the workability deteriorates, and the cost rises. Moreover, the working environment is significantly deteriorated by the dust generated during the cutting process.

Further, when a cable is introduced from the underfloor space into the wall surface, when a high-power cable arranged in the underfloor space 26 and a weak electric cable introduced into the wall surface come into contact with each other, a computer, a telephone or the like is affected by the magnetic field. May be adversely affected.

[0012]

In consideration of the above facts, the present invention facilitates the work of introducing the cable from the underfloor space into the wall surface and does not deteriorate the working environment.
An object of the present invention is to provide a double-floor border material capable of crossing a high-voltage cable and a low-voltage cable arranged in an underfloor space while maintaining a constant distance when introducing the cable into the wall surface. ..

[0013]

According to a first aspect of the present invention, there is provided a double-floor border material, comprising: a floor panel in which support legs grounding on a slab base are integrally formed, and an underfloor space is formed between the base panel and the slab base. The double-floor border material laid adjacent to the wall surface is characterized in that the support leg is formed with an opening capable of being wired from the underfloor space to the wall surface.

The border material for a double floor according to claim 2 is
In the double-floor border material, in which the support legs for grounding are integrally molded on the slab base and placed adjacent to the floor panel and wall surface that form the underfloor space between the slab base and the floor material, It is characterized in that a cutting line capable of forming a wireable opening is formed in the support leg.

[0015]

With the double-layered border material having the above structure, the border panel portion integrally formed with the support leg is cut in accordance with the surplus space. Next, the vicinity of the cut end of the border panel is placed on the support block, and the floor end treatment of the surplus space is completed.

Since the support leg is formed with the opening, wiring can be easily performed from the underfloor space into the wall surface. Also, by forming this opening in the upper part of the support leg,
Since the cable arranged in the underfloor space and the cable introduced from the underfloor space into the wall surface cross at a constant interval, the high-power cable does not adversely affect the low-power cable. Further, a cutting line capable of forming an opening is provided on the supporting leg, and the supporting leg is bent along the cutting line to form the opening, whereby only the necessary opening can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an office double floor 10 to which the double floor border material 18 of the first embodiment is applied.

In the double floor 10, a floor panel 16 is placed on a support block 14 arranged at a predetermined interval on a base sheet 12, and a double floor border material 18 is arranged in an excess space around the floor block 16. It forms the floor surface.

The base sheet 12 is made of synthetic resin having a thin film shape and is adapted to cope with fine irregularities on the slab base 20 when laid on the slab base 20.

In this embodiment, the size of the base sheet 12 is 500 mm in length × 500 mm in width × 1 mm in thickness, and the supporting blocks 14 are arranged and welded at equal intervals.
Therefore, the base sheet 12 processed into this certain size
Support blocks 1 by laying the slabs on the slab base 20
4 can be arranged at a predetermined interval.

The support block 14 has a substantially cylindrical shape with a top surface portion 22 and a slightly enlarged lower portion, and transfers the load to the slab base 20 evenly. Support block 14
The lower edge of is a circular plate 24 that is widened in the radial direction and is welded to the base sheet 12. The floor panel 16 and the slab base 2 placed on the support block 14
An underfloor space 26 is formed between 0 and 0, and a cable C such as an OA device is routed.

The floor panel 16 is made of a square synthetic resin and has substantially arcuate projections (not shown) formed at its four corners. The projections are circular at the center of the top surface 22 of the support block 14. By engaging the annular groove 30 formed so as to leave the shaped protrusion 28, the positional displacement of the floor panel 16 is prevented.

In the extra space with the wall surface where the floor panel 16 having a constant size cannot be placed, the double-floor border material 1 is used.
8 are arranged. The double-floor border material 18 is formed by integrally molding a border panel portion 32 that serves as the floor panel 16 and a support leg 34 that serves as the support block 14. The double-floor border material 18 is preferably made by extrusion molding a material such as a synthetic resin or a light metal in order to secure a predetermined supporting strength.

The border panel portion 32 is the floor panel 1
An upper flange 36 having a top surface that is the same as the top surface of 6 and having a rectangular planar shape, and a lower flange 38 mounted on the support block 14 are arranged in parallel with each other. A large number of webs 40 are arranged between the upper flange 36 and the lower flange 38, whereby the upper flange 36, the lower flange 36 and the web 40 integrally form a floorboard having a plurality of box-shaped cross sections. Since the border panel section 32 has a box-shaped cross section as described above, floor rigidity can be increased.

The support leg 34 has a leg length reaching from the upper flange 36 to the slab base 20, and supports the top surface of the border panel portion 32 and the floor panel 16 at the same height. A plurality of these support legs 34 extend in the longitudinal direction (arrow A direction) of the border panel portion 32 at predetermined intervals. Slits 44 are formed in the longitudinal direction intermediate portions of the support legs 34 at predetermined intervals in the height direction of the support legs 34. By thus providing the slits 44 and cutting the edges, the support legs 34 follow the unevenness of the slab base 20, so that the double-floor border material 18 can be arranged without rattling.

In addition, openings 60 and 62 are formed vertically in the elevation of the support leg 34, and the wall material 43 and the concrete wall 6 are formed.
The wiring space 66 formed in the wall surface between the wiring space 4 and the underfloor space 26 communicates with each other. As a result, the support leg 34
The cable C arranged in the floor space 26 is introduced into the wiring space 66 through the openings 60 and 62 even if the cable C is not cut. Here, as shown in FIG. 2, when the cable C passing through the opening 62 is introduced into the wiring space 66 on the wall surface,
Although the cables C arranged in the underfloor space 26 are inevitably crossed, since the openings 62 are formed at positions apart from the slab base 20, the cables C cross each other with a certain distance. Therefore, for example, due to the generation of the magnetic field, the high-power cable does not adversely affect the low-power cable and does not generate noise in the telephone or the like.

Next, the construction procedure of the embodiment of the present invention constructed as described above will be explained. As shown in FIG. 1, the base sheet 12 to which the support blocks 14 are welded at a predetermined interval from an arbitrary wall surface is laid on the slab base 20 without any gap. After laying the base sheet 12, the base sheet 12
Various cables will be placed on top of the. The floor panel 16 is then placed on the support block 14 to form the major portion of the double floor. Floor panel 1 of a certain size at this time
Since there is an extra space in which 6 cannot be placed, it becomes necessary to perform edge processing.

Here, the border panel portion 32 of the double-floor border material 18 is cut along the longitudinal direction in accordance with the size of this extra space and placed on the slab base 20.
It is to be noted that it is better to apply an adhesive material to the grounding surface of the support leg 34 and fix it to the slab base 20 so that the double-floor border material 18
It is also preferable to prevent the deviation.

Next, the required cable C is pulled out from the underfloor space 26 and introduced into the wiring space 66 in the wall surface through the openings 60 and 62. The openings 60 and 62 are previously formed in the support legs 34.
Therefore, it is not necessary to cut the openings 60 and 62 each time the cable C is introduced into the wiring space 66, and the workability is improved. Moreover, since dust is not generated by the cutting process, the working environment is not deteriorated.

Finally, a carpet 50 or the like as a finishing material is spread over the floor surface formed by the double floor 10.

A skirting board 52 is attached to the wall surface abutting the double-floor border material 18 to fill the gap between the abutting surface of the carpet 50 and the wall surface.

Next, a double-floor border material 70 of the second embodiment.
Will be described. As shown in FIG. 4, a pair of slits 74 capable of forming an opening of the double-floor border material of the first embodiment are formed in the support leg 72 of the second-floor border material 70 of the second embodiment. It is provided in the height direction of 72. This support leg 72 can be easily folded by holding the free end portion which is cantilevered by the slit 74, so that the opening 7 as shown in FIG.
6 can be formed. For this reason, it is possible to save the labor of machining and cutting and to open only the necessary portion of the support leg 72, so that the rigidity of the support leg 72 is maintained.

In the double floor border material 73 of the third embodiment shown in FIG. 6, a plurality of slits 78 having different lengths in the height direction are formed. As a result, the area of the opening 80 can be adjusted according to the number of passing cables, as shown in FIG.

Further, as shown in the fourth embodiment shown in FIG. 8, the double-floor border material 82 may be formed of a foam material.

Note that the openings 60 and 62 are not limited to the opening positions of the above-described embodiment, and as shown in FIGS. Further, as shown in FIG. 3, the double-floor border material 18 of the present embodiment can be applied to the case where the cable C is arranged to penetrate the partition wall 84, and its utility value is great.

[0036]

As described above, in the border material for a double floor according to the present invention, an opening for introducing the cable from the underfloor space into the wall surface is formed in advance in the support leg, or
Since it can be easily formed, the work of introducing the cable from the underfloor space into the wall surface becomes easy. Further, since it is not necessary to process and cut the opening, dust is not generated and the working environment is improved.
