DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flooring for renovation, which can be easily applied to a floor of a building such as a house without peeling an old carpet or a carpet and using an adhesive. About.

[0002]

2. Description of the Related Art Conventionally, when a floor of a building such as a house is renovated from a carpet or carpet to a wooden floor, the old carpet or carpet is once peeled off and removed.
Further, after the floor material underneath was adjusted again and smooth, a new floor material was stuck thereon. In general, the floor material is stuck to the floor base material using an adhesive or, in some cases, using nails or staples. As a simple construction method without using an adhesive, a nail, a staple, or the like, a conventional surface fastener using a hook-shaped engagement element and a loop-shaped engagement element (Japanese Patent Laid-Open No. 4-194167).
JP-A-3-202551) and a brushed fastener (JP-A-10-102730).

[0003]

However, the work of replacing the floor from a carpet or carpet to a wooden floor as described above requires not only the work of peeling an old carpet or carpet but also much labor and labor. If the old adhesive remains on the flooring material after it has been peeled off and remains, or if the carpet or carpet is forcibly peeled off, the surface of the flooring material will lose its smoothness. I was hurt.

[0004] In addition, re-attaching a new flooring material after peeling an old carpet is not only a very labor-intensive and labor-intensive operation, but also a smooth surface without unevenness when the surface of the flooring material is damaged. Sticking was a tricky technique.

The hook-and-loop fastener disclosed in Japanese Patent Application Laid-Open Nos. 4-194167 and 3-202551 combines a hook-type engaging element and a loop-type engaging element. For the first time, a fixing force is exerted, and two types of engaging elements, a hook-shaped engaging element to be adhered on the floor base material and a loop-shaped engaging element to be adhered to the back surface of the floor material, are used. When the floor material is adhered to the floor base material, it is necessary that the positional intervals between the floor members are the same and parallel to each other. Therefore, the fixing force is reduced by half unless the engaging element is stuck very accurately. In addition, it takes a lot of time and labor to improve the sticking accuracy, and the construction cost is high. Further, in order to impart soundproofing performance to the floor material, it is necessary to attach a sound insulating cushioning member between adjacent hook-and-loop fasteners, which is also very disadvantageous in cost. Also, Japanese Patent Application Laid-Open No. 10-1
The same can be said for the other brushed fastener disclosed in Japanese Patent No. 02730.

[0006] An object of the present invention is to provide a flooring material for renovation in which when a floor is replaced from a carpet or a carpet to a wooden floor, the flooring material can be extremely easily attached and constructed without peeling off the old carpet or the carpet. Is to do.
