Description

[Detailed description of the invention] The present invention relates to a carpet installation method.

Conventionally, the method of constructing carpet is to spread cushion material on the floor, attach the carpet to the top surface, stretch it, and hook the edge of the carpet to an edge needle to prevent the carpet from stretching (the clipper method). ), and a method (peel-up method) in which an adhesive is applied to the floor and a composite product of carpet and cushion material is bonded together to prevent the carpet from stretching is known.

However, the former method requires a skilled technique for stretching the carpet when it is laid, and has the drawback that the construction cost is high. There is also a risk that the pins used for fixing will come out.

The latter method is easy to construct and the construction cost is low, but it has the disadvantage that shipping and processing costs are high because the carpet and cushion materials are combined. Also, when removing carpet from the floor when replacing it,
When the cushion material is, for example, a foamed sheet, the skin strength is weak, so the foamed sheet tends to break and remain on the floor.

The object of the present invention is to solve the above-mentioned conventional problems and provide a carpet installation method that has excellent various characteristics.

In other words, the carpet installation method of the present invention is as follows:
A plurality of composite sheets with no elongation and contraction, which are laminated with a fibrous sheet and a high elastic sheet made of polyolefin synthetic resin foam and having through holes penetrating from the front surface to the back surface, are placed on the floor. The feature is that a carpet is attached to the top surface using adhesive.

The present invention will be explained below with reference to the drawings showing one embodiment thereof.

FIG. 1 is a cross-sectional view showing one embodiment of the carpet installation method of the present invention, and FIGS. 2 and 3 are cross-sectional views showing an example of the composite sheet used in the present invention.

In the figure, reference numeral 1 is a composite sheet that does not stretch or shrink, in which a fibrous sheet 3 is laminated on a high elastic sheet 2. According to the present invention, the composite sheet 1 has a structure in which a fibrous sheet 3 is laminated on one side, on both upper and lower surfaces, or in the middle of a high elastic sheet 2. Then, in the composite sheet 1, leaving the fibrous sheet 3 laminated on the upper surface, up to the fibrous sheet 3 on the lower surface of the high elastic sheet 2, or two high elastic sheets 2
In the case of a composite sheet 1 formed by laminating a fibrous sheet 3 in between, a large number of through holes 4 penetrating from the front surface to the back surface of the high elastic sheet 2 are bored.

This composite sheet 1 has the above-mentioned structure, so that it is a cushion material with no elongation/shrinkage and an elongation/shrinkage of 10% or less at a temperature of 60°C.

In the present invention, as shown in FIG. 1, a large number of the above-mentioned composite sheets 1 are placed side by side on a floor surface 5. In this case, the composite sheet 1 and the floor surface 5 are not bonded together. After placing a large number of composite sheets 1, an adhesive 6 for fixing the carpet 5 is applied to the upper surface of the composite sheet 1. After that, the carpet 5 is pasted and the carpet is installed.

2 and 3 show an example of the composite sheet 1. FIG. As shown in FIG. 2, the fibrous sheet 3 may be laminated on both the upper and lower surfaces of the high elastic sheet 2, or as shown in FIG. 3, the fibrous sheet 3 may be sandwiched between the high elastic sheets 2. It is also possible to have a structure in which the layers are stacked so as to penetrate into each other. Even in this case, the fibrous sheet 3 is laminated on the top surface of the highly elastic sheet 2. By laminating the fibrous sheet 3 on the top surface of the high elastic sheet 2 in this way, the composite sheet 1 can
It can be made into a cushion material with no elongation/shrinkage and an elongation/shrinkage of 10% or less at 60°C.

When the fibrous sheet 3 is laminated on both sides of the highly elastic sheet 2, the surface strength, especially the tensile strength, of the highly elastic sheet 2 is improved. In addition, two high elastic sheets 2
When laminated between them, a composite sheet 1 having even better dimensional stability in addition to the above can be obtained.

In this case, if a reinforcing layer such as a fibrous sheet 3, such as kraft paper, is attached to the outside of the high-elastic sheet 2, elongation and shrinkage will be further reduced and dimensional stability will be improved.

Furthermore, in the case of a composite sheet formed by laminating the fibrous sheet 3 on the upper surface of the high-elastic sheet 2 up to the fibrous sheet 3 on the lower surface of the high-elastic sheet 2 or between two high-elastic sheets 2, , a large number of through holes 4 penetrating from the front surface to the back surface of the high elastic sheet 2
It is preferable to make the hole by a needle punch or the like. The reason why the through holes 4 are not provided in the fibrous sheet 3 laminated on the upper surface in this way is to prevent the adhesive 6 used when bonding the carpet 5 from entering the through holes 4 and closing the through holes 4. It is in.

The diameter of the through holes 4 is preferably 3.0 mm or less, and the density is preferably 30 or less per cm ² . If the diameter of the through hole 4 is too large or the density is too high, the strength and cushioning properties will deteriorate, which is not preferable. Further, if the density of the through holes 4 is low, the effect of providing the through holes is hardly seen.

The fibrous sheet 3 used in the present invention is preferably woven fabric, nonwoven fabric, or paper such as kraft paper.

It is also possible to impart an insect repellent effect by coating the surface of the fibrous sheet 3 or impregnating the interior with an insect repellent. Insect repellents include pyrethrin, Delis agent, nicotine agent, pine resin mixture, machine oil emulsion, DDT,
BHC, chlorine-based insect repellents such as Aldrin,
Examples include organic phosphorus agents such as TEPP, parathion, EPN, and malathion, and naphthalene, all of which are used in solutions of appropriate concentrations.

In addition, as the high elastic sheet 2, polyethylene,
Closed-cell olefin-based synthetic resin foam sheets made of polypropylene, ethylene-based copolymers, etc. are suitable, and these are usually made of fibers with the insect repellent applied to the surface or impregnated inside using an adhesive. It is joined to the quality sheet 3.

In the present invention configured as described above, only the carpet and the composite sheet need to be bonded on-site, and the floor surface and the composite sheet are not bonded, so a small amount of adhesive is required, and when replacing the carpet from the floor surface. It can be easily peeled off.

Furthermore, with composite sheets that have a structure with many through-holes, even if a heavy object is placed on the high-elastic sheet for a long period of time, which may dent it, air will quickly enter the through-holes when the object is removed, causing the sheet to dent. does not occur.
