Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a floor finishing material, particularly a direct-adhesion floor material such as a concrete house.

[Prior Art and Problems Thereof] There is a floor material to be bonded and attached in a concrete house or the like without arranging joists, which is disclosed in Utility Model Publication No. 61-85608.

This is because a plurality of long materials having real parts for joining formed on the end faces on the four sides are slightly displaced, the long-side real parts are fitted and arranged in parallel, and the cushion sheet material is attached to the lower surface. It is connected.

In this flooring material, the joints are not conspicuous when the flooring materials are continuously arranged in a vertical direction, and the back sheet can be cut in accordance with a predetermined area so that each long material can be divided and used. It has the advantage of going up.

However, it is necessary to cut off the stepped portion in order to align the short side portions of each long material with a straight line at the wall side on the short side side and at the end of the pasting.

Further, since they are connected in a staggered manner, the manufacturing is complicated, dimensional accuracy is required, the size of the packaging becomes large, and there is a drawback that the stepped portion is easily hooked at the time of construction and transportation to be divided.

On the other hand, for flooring with short sides formed in a straight line, a plurality of decorative veneers are arranged in the width direction as disclosed in Japanese Utility Model Publication No. 62-31643. There is also a chamfered part at the upper end corner of the direction end so that the floor material seam part is not conspicuous, but a groove is formed at the contact part of the chamfered parts but at the contact part of the non-chamfered parts. Has a defect that a linear joint appears and the joint between floor materials looks unnatural.

[Purpose] The present invention is intended to make the joint between the flooring members inconspicuous in the vertical direction and improve the manufacturing, transporting, and workability.

[Means for Solving the Problems] In order to solve the above problems and achieve the object, the present invention has a real part for joining on four side end faces, and a groove is formed in the lateral direction of the surface. And a long member A having an upper end portion on the short side side formed into an inclined surface and having a seam portion of the surface decorative plate between the grooves or between the groove and the inclined surface, and a real portion for joining on the four side end surfaces. , A long material B having a groove formed in the lateral direction of the surface and having a short-side upper end formed into a substantially right-angled surface and having a seam portion of the surface decorative plate between the grooves, and the short sides thereof are linearly Aligning the long side real parts with each other and arranging them in parallel, the cushion sheet material is attached and connected over the lower surfaces of the plurality of long materials.

[Operation] When the flooring materials according to the present invention are vertically connected to each other,
A recess is formed at the abutting portion between the long members having the short-side upper end formed as an inclined surface, while the abutting portion having the short-side upper end formed as a substantially right-angled surface is linear.

As a result, the groove formed in the lateral direction of the surface of the long material, the concave line formed by the inclined surfaces, and the abutting portion formed by the substantially right-angled surface and the seam portion of the surface decorative plate work together. That is, they are mixed on the floor finish surface, and the seams between the floor materials become inconspicuous.

Moreover, since the cushioning material is attached to the back side, if the edge is pressed against the adjacent flooring material during vertical jointing, a springback of the cushioning material may urge it in the abutting direction to create a gap. In addition, since the unevenness of the groundwork is absorbed and the step difference is reduced, the seam can be made more inconspicuous.

[Structure of the Present Invention] The present invention shown in the drawings will be described in detail below with reference to an embodiment. FIG. 1 is a plan view of a flooring material and FIG. 2 is a longitudinal sectional view. FIG. 3 and FIG. 4 are cross-sectional views of the joint portion in the construction state, and FIG.
The figure shows a long material B and a joint portion between the long materials.

In FIG. 1, 1 is a real part for joining, 1a is a male part, and 1b is a real part.
Is a groove, 3 is an engraved groove, 3 is an inclined surface formed on the short-side upper end of the long material A, and 4 is a substantially right-angled surface formed on the short-side upper end of the long material B.

Reference numeral 6 denotes a joint portion of a surface decorative material such as a wood veneer, and the presence of the joint portion 6 makes the joint between the long members B and B, which will be described later, mixed with the joint portion 6 so that the joint between the floor members becomes less visible.

In the embodiment, four long members A and B are alternately fitted and connected in parallel, but the effect of the present invention can be obtained even if two long members A and B are connected in parallel.

In FIG. 2, reference numeral 5 denotes a cushion sheet material, which is an elastic sheet material such as a foamed resin sheet, a fibrous cushioning material, or a rubber sheet.

In the embodiment, the flat cushion sheet material 5 is arranged, but in order to improve the cushioning effect and the compatibility with the base material, a plurality of concave grooves or cut grooves, uneven portions, through holes, non-penetrating holes are formed on the upper surface or the lower surface. It may be a cushion sheet material provided with holes, or a cutting instruction line may be provided on the lower surface of the cushion sheet material located at the fitting portion of the long members A and B.

As shown in FIG. 3, the long strips A and the joints between the A strips are formed with the recessed strips 3a by the inclined surfaces 3 and 3, and the long strip A after the construction is completed.
It is confused with the groove 2 formed on the surface of B in appearance.

As shown in FIG. 4, linear members 4 a are formed by the substantially vertical surfaces 4 and 4 at the joints between the long members B and B, but they are less noticeable than the groove 2.

[Effect] Since the flooring material according to the present invention is configured as described above, when the flooring materials are vertically connected to each other and are continuously connected, the long material materials having the sloped upper end on the short side are formed. While a ridge is formed at the abutting portion, the abutting portion in which the short-side upper end portion is formed into a substantially right-angled surface has a linear shape. As a result, the groove formed in the lateral direction of the surface of the long material, the concave line formed by the inclined surfaces, and the abutting portion formed by the substantially right-angled surface and the seam portion of the surface decorative plate work together. That is, they are mixed on the floor finish surface, and the seams between the floor materials become less noticeable.

Moreover, since the cushion sheet material is adhered to the back surface, a gap is less likely to occur, and the unevenness of the base is absorbed to reduce the level difference, thereby making the seam even more inconspicuous.

In addition, since long materials are connected in a rectangular shape, mass production is possible without requiring special rulers, mold materials, etc. in manufacturing, and the processing accuracy is high.

Furthermore, the packaging can be made smaller, and like the conventional square flooring, it can be attached from the end without cutting, it does not require skill for construction, and it does not easily decompose even if it is handled roughly. is there.
