Description

Description: TECHNICAL FIELD The present invention relates to a technique for preventing sinking at an edge of a floor having soundproofing performance.

[Prior Art] Conventionally, a flooring 3 having a cushioning material 2 on a lower surface portion as shown in FIG. 2 is laid on a floor base 1 to form a floor having excellent soundproofing performance. I was In order to prevent the floor from sinking, parting, sweeping out, and sinking into the floor at the portion in contact with the wall surface, etc., as shown in FIG. 5, the cushioning material 2 on the lower surface of the flooring material 3 located at the end is used. Part of the end is peeled off to position the joist 20 to prevent the end of the flooring material 3 from sinking by the joist 20 or a push pin member 21 as shown in FIG. 6 (b). As shown in FIG. 6 (a), a large number of pieces are driven into the lower surface of the end of the floor material 3 to prevent sinking.

[Problems to be Solved by the Invention] In the above-described conventional example, a part of the cushion material 2 is peeled off, the edge joist 20 is constructed, and a push pin member is used.
In addition, it takes time and effort to drive 21 and furthermore, it is necessary to cut and use the flooring 3 on site due to the layout in the width direction. There was a problem that loss was caused by not using.

The present invention has been made in view of the above-described problems of the conventional example, and an object of the present invention is to prevent sinking at the edge of the floor without using a joist or a push pin member as in the related art. Another object of the present invention is to provide a floor structure capable of allocating the floor without cutting the floor material in the width direction.

[Means for Solving the Problems] The floor structure of the present invention has a structure in which a floor material 3 having a cushioning material 2 on a lower surface portion is laid on a floor substrate 1 and a narrow portion of the floor substrate 1 which is an edge of the floor is provided. In this case, the above-described object of the present invention has been achieved by adopting such a configuration.

[Operation] In constructing a floor, a floor material 3 having a cushioning material 2 on a lower surface is laid on a large part of a floor base 1,
By laying the subsidence preventing floor material 4 having a bad cushion at a portion to be the edge of the floor base 1, it is possible to prevent the subsidence at the edge of the floor. And since the sinking prevention end piece 4 is narrow, when laying the floor, the narrow sinking prevention end piece 4 is laid, or two or three sheets are laid. By adjusting the number of laid end materials 4, the floor materials 3 can be allocated without cutting in the end direction.

EXAMPLES The present invention will be described below in detail based on examples shown in the accompanying drawings.

For example, as shown in FIG. 2, a plurality of flooring elements 5 such as decorative veneer plywood are displaced in a stepwise manner on a cushioning material 2 such as a rubber cushioning material as shown in FIG. Urethane rubber 7 is filled in a concave portion 6 provided opposite to the side of the adjacent floor element 5 and the adjacent floor elements 5 are fixed via the urethane rubber 7. The flooring 3 having the above configuration is provided with fitting projections 8 at one end in the longitudinal direction and one end in the width direction, and the other end in the longitudinal direction and the other end in the width direction. A fitting concave portion 9 having a shape to be fitted to the fitting convex portion 8 is provided.

The low-cushioning anti-subsidence floor material 4 having a low cushioning property is constituted by laminating a backing material 10 such as a low-cushioning carp material on the lower surface of a floor element 5 ′ such as a veneer veneer. In this case, the width of the floor element body 5 'constituting the main body of the anti-subsidence floor material 4 is set to an integral fraction of the width of the floor material 3, and the same surface material as the veneer is used. Used. At one end of the floor element 5 ', a fitting projection 8' or a fitting recess is provided.

Therefore, when constructing the floor, Fig. 3 (a)
The construction is performed in the order of (b) and (c). That is, a floor material 3 having a cushioning material 2 on a lower surface portion is laid on a floor substrate 1 such as a slab, and a narrow anti-subsidence floor edge having a narrow cushioning property is provided at a portion of the floor substrate 1 which becomes an end of the floor. In this case, as shown in FIG. 3 (a), in consideration of the layout of the entire floor, the subsidence preventing floor scraps 4 are arranged in one or two rows along the wall 11 in some cases. Is to lay three or more rows and adhere to the floor substrate 1 with an adhesive, and then spread the floor material 3 one after another and fix it to the floor substrate 1 with the adhesive, and finally sink in the opposite wall 11. The prevention floor scrap 4 is laid on the floor substrate 1 and fixed by an adhesive. Then, the adjacent floor members 3 are fitted with the fitting convex portions 8 and the fitting concave portions 9, and the floor material 3 and the sinking floor end member 4 are fitted with the fitting concave portions 9 and the fitting convex portions 8 ′. Alternatively, the fitting convex portion 8 and the fitting concave portion of the floor material 4 for preventing sinking are fitted. The floor material 3 uses the left or right side of the cut portion as shown by the broken line in FIG. 4 in the portion where the longitudinal end is located on the wall 11 'side. In this case, the rest of the cut is used on the side of the opposite wall 11 '. FIG. 3 (b) shows a case where the cut floor material 3 is laid near the wall 11 '.

[Effects of the Invention] In the present invention, as described above, a floor material having a cushion material on the lower surface is laid on the floor base, and a narrow sunk with poor cushioning property is provided at the end of the floor of the floor base. The squat-prevention floor edge material is laid, so that it is possible to prevent sinking at the edge of the floor without using a joist or a push pin member as in the related art. Therefore, when laying the floor, adjust the number of narrow subsidence prevention slabs by laying one or two or three narrow subsidence prevention slabs. Materials can be allocated without cutting in the end direction.
