Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to flooring for buildings and other buildings, and in particular to an improved floor finishing structure that provides a smooth finished surface for floors that include floor wiring. The present invention also relates to floor finishing methods and the provision of flooring materials suitable therefor.

[Conventional technology]

In computer rooms and factories that handle electronic components, double-walled raised floors with a height of about 30 to 40 centimeters are used to accommodate wiring materials that run in all directions on the floor and to provide air conditioning. A floor structure is used.

On the other hand, buildings with advanced information technology and offices with advanced office automation (OA), which are called intelligent buildings, are
For various types of wiring such as data, it has the flexibility to accommodate NCL of equipment, relocation, and changes in desk layout, and also eliminates exposed wiring to improve the office environment. A simple raised floor system of about 10c is adopted.

By the way, since livability is important for floors in offices, fibrous carpets are recommended and are used as decorative materials on such raised floors.
In certain areas, such as computer rooms or laboratories, the application of plastic tiles may be preferred over the application of such fibrous carpets, and thus may be of a similar thickness and weight to such carpets. The applicant has developed and provided a plastic tile made of a homogeneous vinyl material, which has a tile shape and has a backing layer that is easily deformable on the back side.

These free-standing plastic tiles were developed to be able to be applied on top of raised floor panels, and are designed to avoid irregularities in the surface due to the material and finish of the panels, as well as steps and gaps between adjacent panels. The idea was to absorb this by deforming the soft backing layer, thereby creating a smooth floor finish.

[Problem to be solved by the invention]

However, in the developed plastic tile, the absorption of unevenness etc. in the raised floor plate is difficult.
It depends on the thickness of the backing layer, and in order to ensure such absorption, the thickness of the backing layer can be increased, but even if the backing layer is installed with the legs of a desk, chair, or equipment,
There is a possibility that the tile body itself, that is, the surface portion, may be deformed due to the load applied to the legs, and it may not be possible to achieve the smooth floor finish that is originally required of this article.

By the way, in conventional flooring, a thin and flexible metal plate such as tin plate is used as a core material, and a plastic plate such as vinyl is laminated and integrated on the front side of the core material. A metal/plastic composite floor tile with an integrally laminated backing layer of foamed plastic or the like on the side has been proposed. (Refer to Japanese Utility Model Publication No. 54-11712.) However, the main purpose of the proposed tile metal plate was to suppress the thermal expansion and contraction caused by temperature changes in plastic materials. In order to blend in with the unevenness (unevenness) of the base,
It is easy to transform.

Therefore, with such a flexible metal plate, it is difficult to suppress the deformation of the plastic plate forming the surface due to the weight of the desk or equipment installed on the floor, and the above-mentioned problem cannot be solved.

In view of the problems of the prior art described above, the present invention aims to provide a floor finishing structure and a floor finishing method that can reliably finish a floor with a smooth surface, as well as a flooring material used therefor. be.

[Means for Solving the Problems] According to the present invention, the above problems can be solved by providing a relatively hard plastic plate for the surface layer, a relatively soft rubber/plastic plate for the back layer, and By using a metal plate with a certain rigidity as a layer,
I am making it happen.

The plastic plate for the surface layer has the hardness, thickness, color, pattern, etc. required for a floor finishing material, so it is recommended to use vinyl chloride tiles, which have been used conventionally, or something with equivalent performance. good.

In addition, the soft rubber/plastic plate for the back layer needs to have a certain thickness and softness in order to adapt well to and absorb the unevenness of the floor surface. It is a foamed plastic plate, urethane foam can also be used, and in some cases, felt can also be used.

Furthermore, the rigid metal plate of the intermediate layer has a large resistance to deformation in the thickness direction, that is, when pressed against the upper and lower surfaces, and is hard enough to block the influence of stress in the vertical direction, yet it is possible to specify a predetermined thickness. This is important, and anti-corrosion treated steel plates are available as a material that satisfies this requirement.

Lamination integration can be achieved by bonding these layers together using adhesives or double-sided adhesive sheets, etc. At that time, it is possible to achieve so-called unitization that is completed in advance before floor finishing. Alternatively, they may be combined when finishing the floor.

Particularly when using the former method, it is preferable to form a tile-like structure with specified vertical and horizontal dimensions in the laminated uni-nod of each layer.

On the other hand, when using the latter method, first, an integrated laminated structure of a soft plastic plate as a lower layer and a rigid metal plate as an intermediate layer is laid down, and then a hard plastic plate as a surface layer is placed on top of the laid metal plate. can be applied and integrated to achieve the desired floor finish.

In this case, the hard plastic plate on the surface layer can be separated from the rigid metal plate on the middle layer, and the vertical and horizontal width dimensions can be selected arbitrarily, so by setting the width larger, a floor surface finish with fewer seams can be achieved. be able to.

Which of these methods to choose should be decided depending on the situation of the floor finishing place.

The above-mentioned flooring material can be used directly on a concrete floor surface, but it can also be used as a surface decoration of a raised floor panel body for a double floor configuration. In this case, by staggering the joints of the raised floor panels and the joints of the flooring material, it is possible to avoid steps and gaps between the panels due to unevenness of the concrete floor surface on which the panels are laid. This can be absorbed by the deformation of the underlying soft plastic plate, and the rigid metal plate can serve as a bridging reinforcing member between panels with gaps.

〔Example〕

Hereinafter, a more detailed description will be given based on the attached drawings.

FIG. 1 shows one embodiment of the flooring material provided by the present invention.

The flooring material 1 here is made into unit tiles with predetermined width dimensions in the vertical and horizontal directions, and includes a hard plastic plate 2 as a surface layer, a rigid metal plate 3 as an intermediate layer, and a soft metal plate as a lower layer. Plastic plates 4 are laminated and integrated in advance to form a unit.

Table 1 shows that the hard plastic plate 2 is made of vinyl chloride, the rigid metal plate 3 is a galvanized steel plate, and the soft plastic plate 4 is made of foamed polyethylene. This shows the test results of the degree of deformation in the thickness direction when the thickness of each layer was changed in a three-layer structure with surfaces joined with adhesive, and compared to conventional floor-fixed vinyl tiles. Contents equivalent to JIS residual paper test, 36k for 4.5mlφ indenter
A load of g (Kg/cd to 2λ) was applied to the sample, and the sample was left on top of the height, and the amount of dent in the sample at that time and the amount of remaining dent after the load was released were determined.

As is clear from the table, especially when the thickness of the galvanized steel sheet in the intermediate layer is Q, which is very thin at 5 mm, both the dents and residual dents during load bearing are large, but between 0.8 mm and 1 m.
It becomes extremely small at m. Therefore, 0.8mm~11■
It was recognized that a thickness of approximately

In addition, the vinyl chloride tiles 2 on the surface layer were 2 to 4 mm thick, but the galvanized steel plates 3 were laminated together.
Since there is no difference in the transformation to , from an economic standpoint, the two-dragon version was deemed appropriate.

Based on the above results, we adopted a vinyl chloride tile with a thickness of 21 mm for the hard plastic plate 2 on the surface layer, a galvanized steel plate with a thickness of lw for the metal plate 3 on the middle layer, and For the soft plastic board 4, a foamed polyethylene board with an appropriate thickness is used to absorb the unevenness of the base, and these are laminated together with adhesive to form a unit tile with vertical and horizontal dimensions of 45 Qn + x 450. As a result, it was confirmed that a flooring material suitable for the purpose mentioned above could be obtained.

Figure 2 shows the unit tile l made as described above.
This is an example of applying it as a decorative surface for a raised floor.
For a free access floor panel 6 with the dimensions of H1 and its supporting legs 7, a flooring l made of the above-mentioned material and dimensions is used to straddle the joints 8 caused by the laying of the panel 6. It was placed so that it would be covered with a layer of paper and a certain makeup was applied to it.

In addition, 9 is an electrical wiring material passed through the space below the panel 6.

By doing this, the gap G that occurs at the joint 8 between the panels 6 due to the unevenness of the concrete base 5 is filled by the deformed press-fitting of the foamed polyethylene plate 4 of the lower layer, and the level difference that occurs at the joint 8 is , is also absorbed by the deformation of the foamed polyethylene temporary 4, and the influence thereof is blocked by the rigid galvanized steel plate 3, making it possible to finish the floor with a smooth surface without deforming the surface vinyl chloride plate 2. It is something.

In addition, a steel desk or OA is placed on the surface PVC board 2.
When the table on which the equipment was placed was placed, no dents were found in the vinyl chloride board 2. This proves that the rigid metal plate 3 resists the load of the desk, etc., and suppresses deformation of the surface layer of the plastic plate 2.

Note that the periphery of unit tile 1 is chamfered (
(see 10 in FIG. 1), and the construction error when the chamfered portions are laid can be adjusted by cutting the chamfered portions.

FIG. 3 shows another embodiment of the flooring material provided by the present invention, in which a lower layer soft plastic plate 4' and an intermediate layer rigid metal plate 3', which have a predetermined width dimension, are bonded together. It consists of an integrally laminated composite of the lower layer and the intermediate layer, and a hard plastic plate 2' as the surface layer, which is separated from this.In construction, the composite of the lower layer and the intermediate layer is first laid down. Then, the surface hard plastic plate 2' is placed on top of the floor to complete the desired floor finish.

In addition, if vinyl chloride tiles are used for the hard plastic plate 2' and a galvanized steel plate with a thickness of 1 fl is used for the intermediate metal plate, the thickness should be about 411 mm from the viewpoint of installation. .

According to the flooring material 1' constructed in this embodiment, it is possible to finish the floor with a smooth surface like the above-mentioned unit tiled flooring material 1. Since the width dimension can be selected separately from the metal plate 3', it is possible to make the width dimension larger than the metal plate concerned and perform construction with fewer joints on surfaces such as covering multiple metal plates with a single plastic plate. becomes. This is possible because the surface of the metal plate is smooth.

〔Effect of the invention〕

As explained above, according to the present invention, the intended purpose of ensuring a smooth floor finish is more than fully achieved, and it also has the effects listed below. can have
