Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an underfloor lining material, and more particularly to an underfloor lining material suitable for mounting OA equipment.

(Prior Art) Recently, many office equipments such as computer terminals and word processors have been installed in offices, so various wiring cords have been installed on the floor. Came. Conventionally, these wiring cords are fixed with a staple, or the groove for storing the cord is fixed on the floor with an adhesive or the like, the cord is put in this, and the surface is covered with a lid that fits into the groove. The means of. However, these methods are not only unsightly as a result of protrusions protruding on the floor, but also inconvenient when moving the objects.

Therefore, as a result of various studies to solve these problems, the present inventor previously provided wiring or piping cavities on the lower surface and slit portions that enable bending to accommodate unevenness of the floor surface. It was found that the underfloor covering made of rigid foamed plate-like material is a suitable material, and it was proposed (Practical application 63-2002).
(See No. 7 (Actual Kaihei No. 1-129339)). That is, in this floor material, the leg portion is provided between the hollow portion for piping and the hollow portion for piping, and the leg portion is divided into four leg members with a cross-shaped slit portion. Are doing

However, when this floor underlayment is constructed, it often breaks more easily than the joints of the subdivisions divided by the slits. When the user walks on the floor surface, a creaking noise is generated between the ground surface and the floor covering, or a rubbing sound is generated by hitting the side walls of the underlaying members.

(Problems to be solved) As a result of various studies to improve the above-mentioned drawbacks, the inventor of the present invention, by lining with a flexible sheet so as to straddle the back surface of the adjacent leg portion, is able to remove the subdivision portion during construction. It was found that the cracks from the joints can be prevented and that the generation of squeak noise is prevented by providing a small convex portion on the side wall of the underfloor material, and the present invention was completed. It is an object of the invention to provide an underfloor covering material that is free from damage during construction and eliminates creaking noise.

(Means for Solving the Problem) The present invention is a rigid foam in which a small partition portion having a leg portion at a corner is connected with a connecting piece so that the small partition portion can be bent through a small gap to correspond to the unevenness of the base. An underfloor lining consisting of a body, which is lined with a flexible sheet so as to straddle the adjacent leg parts of the small compartments, and a small convex portion is provided on the side wall of the underfloor lining. And then
If necessary, in consideration of laying a rug on the upper surface of the underfloor covering material, it is preferable to apply an adhesive to the upper surface of the underfloor covering material in advance and cover it with release paper.

Next, the present invention will be specifically described with reference to the drawings.

FIG. 1 is a perspective view of an underfloor covering according to the present invention. In FIG. 1, a square floor underlayment 1 made of a hard foam is usually broken into nine subdivided portions 2 by slits 4, and each subdivided portion 2 is connected by a connecting piece 3. On the lower surface (rear surface) of the underfloor laying material 1, slit portions 4 and hollow portions 5 are provided alternately and vertically and horizontally from one side to the opposite side. There are legs 6 at the four corners of each subdivided portion 2, and a flexible sheet 7 such as a polyethylene foam sheet is attached to the lower end of each leg with an adhesive or the like so as to straddle adjacent legs. To do.

On the upper surface of the underfloor covering 1, for the convenience of laying a rug,
The adhesive layer 8 may be covered with a piece of release paper, and the sidewalls of the underfloor material are provided with small convex portions 9 in order to eliminate rusting noises from each other. Furthermore, when applying the adhesive, apply the adhesive to the floor, but if you apply the adhesive to the surface of the flexible sheet attached to the legs in advance, the adhesive will not be applied to the floor during the installation. However, it can be easily fixed.

The floor underlayment material of the present invention has a size of about 300 m.
It is about m × 300 mm to 1000 mm × 1000 mm, and the slit portion varies depending on the size of the underlaying material, but, for example, when the underlaying material is a square with a side of about 45 to 55 cm on a plane,
It is preferable that slit portions having a length of 3 to 23 cm and a width of 3 to 6 mm are intermittently provided at intervals of 15 to 18 cm, and the leg portions have a width of 60 to 80 mm and a height of 10 to 20 mm with the slit portion as the center.

The rigid foam used in the present invention is synthetic resin such as expanded polystyrene and expanded polyurethane, and the flexible sheet includes expanded polyethylene sheet and rubber sheet. Further, as the release paper, one obtained by applying a pressure sensitive adhesive to the back side of an ordinary waterproof paper is used.

When the upper surface of the underfloor covering is covered with release paper, the adhesive layer is exposed when the release paper is peeled off, and the cover can be easily laid on it.

(Effect of the device) Since the underfloor lining material according to the present invention can be laid on the ground surface one after another, construction is easy, and since it is covered with a flexible sheet, it does not crack during construction. . The surface on which the underlayment is laid gives a soft walking feeling and is made of foam, so that a heat insulating effect is obtained.
