Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure constructed at an entrance of a house, a living room, a store, and the like, particularly over a relatively large predetermined area in a ground pattern such as a grain pattern or a parquet pattern. The present invention relates to a decorative floor structure that forms a highly designable floor surface on which accent patterns such as mosaic patterns different from patterns are arranged.

[0002]

2. Description of the Related Art An accent pattern part different from the ground pattern by the above surface pattern is partially or scattered on a floor formed by laying floor boards having a single or the same surface pattern. It may be arranged to form a floor surface with a high designability.

[0003] Such an accent pattern portion is formed by using a sliced veneer obtained from a laminated flitch formed into a mosaic pattern, a veneer having a predetermined shape, a veneer lined with a sheet-like material such as paper or non-woven fabric, with an adhesive tape, a hot veneer. A general method is to use a single veneer obtained by bonding with a melt adhesive thread, a hot melt adhesive or the like, or a floor plate in which a mosaic pattern printing paper or the like is adhered to a substrate.

[0004] The above-described method which has been generally adopted in the past, when the individual unit accent pattern portion is small, that is, when the unit accent pattern portion is smaller than the width of one strip-shaped floor plate. By manufacturing a floorboard in which the accent pattern portion is previously incorporated in the surface of the floorboard, it is possible to easily cope with the problem without any problem.

However, the size of the accent pattern is 1
If the floorboard is larger than the width of one floorboard and spans multiple floorboards that are installed adjacent to each other, not only is it difficult to produce a decorative veneer of a size corresponding to the pattern, but also floorboards. It is also troublesome to manage the production, storage, and handling of packaging and transportation. For this reason, it is necessary to separately form different pattern portions on individual floorboards and to form an accent pattern such as a predetermined mosaic pattern only when a plurality of floorboards are combined.

On the other hand, when the pattern of the accent pattern such as the mosaic pattern has a point-symmetric design, for example, as shown in FIG.
The floorboard constituting 0) is divided into a plurality of divided unit boards (30a).
(30b)... And combining these with a normal decorative floor board (40) to cope with the situation. However, in this case, each divided unit plate (30
a) Even though the surface pattern of (30b) is the same, the arrangement of the joints to be formed on the respective outer peripheral side surfaces does not always match with the surface pattern. That is, the arrangement of the male knurl (31) and the female knurl (32) is not the same among all the divided unit plates (30a) (30b)... Due to the surface pattern. For this reason, the method of forming the joint portion of each divided unit plate is different, and a problem occurs in terms of production management, quality control, and the like.

This problem is also caused by the division unit plate (30a).
(30b): Resolving is achieved by so-called butt-joining by butting of vertical side surfaces without joining by each other and joining with the surrounding ordinary floor plate (40). It is possible to do. However, in this case, since the butt joints do not have sufficient joint strength, especially when the floor foundation is a joist group, the joints at the opposing position must be arranged on the joists. In addition, lack of suitability for on-site response,
The size of the accent pattern is also restricted. In addition, when the floor base is a concrete floor slab, the unevenness or unevenness may affect the divided unit plate to cause a step on the floor. Therefore, in order to prevent this, a plywood or the like must be discarded on the floor slab surface, resulting in disadvantages in terms of man-hours and costs. In addition, even if abandoning is applied, it is difficult to completely avoid the occurrence of the above-mentioned floor surface step due to the influence of the level difference that easily occurs between the avalanche boards.

[0008]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention partially arranges an accent pattern portion such as a mosaic pattern having a relatively large area in a ground pattern on a floor surface. The floor with high designability can be constructed in a good flush state by relatively simple construction work, and it can be constructed without any trouble even if the floor foundation is a joist or concrete floor slab. The purpose is to provide a simple floor structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In a typical embodiment of the present invention shown in FIGS. 1 to 5, a floor structure (1) has a plurality of reference floorboards (A) as its constituent members and a plurality of reference floorboards (A). It includes a stepped floorboard (B) and a unit decorative board (C) divided into a plurality of pieces constituting an accent pattern portion such as a mosaic pattern.

The reference floorboard (A) is equivalent to a conventional ordinary floorboard, and is generally provided with a decorative material (3) such as a wooden veneer on the surface of a substrate (2) made of plywood or the like having a predetermined thickness. However, as in the case of the decorative portion of the stepped floorboard (B) described later, a configuration in which a surface plate is adhered on a substrate may be used. The size of the floorboard (A) is generally formed in a strip shape having a thickness of 12 mm, a width of 303 mm and a length of 1818 mm, but a plurality of types having different lengths and widths are mixed. The dimensions are not limited.

On the surface of the reference floorboard (A), the decorative material (3) is used to apply a decorative pattern such as a grain pattern, a parquet pattern, or the like, which constitutes a ground pattern on the floor. Further, on the outer peripheral side surface of the peripheral edge, there is formed a main joint structure (4) composed of male and female knurls in a positional relationship corresponding to that of a stepped floorboard (B) described later.

As shown in FIGS. 6 and 7, the stepped floor plate (B) is provided on a substrate (5) made of plywood or the like, and at one end, both ends or a middle part in the longitudinal direction thereof. Surface plate (6)
And a decorative portion (7) having the same thickness as that of the reference floorboard (A) is formed in a portion of the surface plate (6) to which the surface plate (6) is bonded, while the remaining portion is a surface plate (6). Is formed on the missing step portion (8) in which there is no.

The face plate (6) has a thickness of 3.0 mm by attaching a decorative material (6b) such as a decorative veneer on a base material (6a) such as a plywood.
The surface is provided with the same ground pattern as the surface of the reference floorboard (A) by the decorative material (6b). The end surface of the surface plate (6) on the side of the step (8) is formed substantially in a vertical plane. However, it is preferable that a notch is provided on the lower surface of the peripheral edge of the surface plate (6) so that an adhesive pool is formed there and the adhesive for attaching the surface plate to the outside can be prevented.

On the outer peripheral side surface of the peripheral edge of the stepped floor plate (B),
In the range of the thickness of the substrate (5), a main bonding structure (9) is formed by male and female members.

The width of the stepped portion (8) is equal to the width of the floor plate (B), but its length dimension corresponds to the size of a decorative plate (C) for forming an accent pattern portion described later. Needless to say, it is set by the user.

The production of the stepped floorboard (B) is performed, for example, as follows. First, the base material (6a) of the surface plate (6)
After affixing the decorative material (6b) to the required size and cutting it to a required size, an adhesive is applied to a required portion on the back surface of the front plate (6) or the upper surface of the substrate (5), and the both plates (5) (6) ) And compressed by cold pressing. Then, a dummy plate having the same thickness as the surface plate (6) is detachably attached to the portion of the stepped portion (8) with a double-sided adhesive tape or the like, and then subjected to surface sanding, joint processing with a tenoner, painting, and the like. Then, remove the dummy plate to make the product.

In place of the dummy plate, a surface plate (6)
A rod-shaped material having the same thickness as that described above may be used, and it may be detachably attached to the peripheral portion of the substrate (5), and paper or a release sheet may be detachably attached to a concave portion inside the same. At this time, a rod-shaped material may be partially removably attached to the inside.

The decorative board (C) is one in which an accent pattern such as a mosaic pattern is partially formed in the ground pattern on the floor, and may be constituted by only one sheet. For formation, it is generally configured as a plurality of unit decorative boards as shown in the illustrated embodiment.

When the decorative panel (C) is divided, the decorative panel (C) may be divided in any manner. However, the unit decorative panel as a divided body contains the same pattern from the viewpoint of versatility and workability, and has few types. It is more preferable to take these points into consideration,
It is preferable to determine the divided shape of the decorative board (C). Further, it is preferable that the design of the accent pattern portion is line-symmetric or point-symmetric. In other words, by adopting such a pattern, the number of units having the same shape and the same pattern increases as unit decorative boards, and the place where the unit decorative boards are arranged is not limited to one place, but becomes arbitrary, and Workability can be improved.

The thickness of the decorative board (C) is the same as the thickness of the surface board (6) in the stepped floor board (B). The outer peripheral side surface of the peripheral edge is not subjected to the joint processing by means of a real peeler or the like, and is formed in a substantially vertical plane. ing. The notch (10) is effective in forming a pool of the adhesive when the decorative board (C) is stuck and preventing the adhesive from protruding to the outside, particularly to the surface side.

The decorative board (C) is generally made to have the same configuration as the surface board (6) of the stepped floor board (B). That is, it is general to apply the decorative material (6b) to the base material (6a). However, the pattern on the surface corresponds to the accent pattern to be formed, and must be formed in a pattern different from the surface pattern of the floorboards (A) and (B). Needless to say, the different pattern includes not only the pattern but also all the cases where the color, the texture, and the like are different.

The decorative plate (C) may be chamfered at the surface end or may be formed with surface grooves. Groove processing may also be performed on the back surface. The groove processing on the back surface not only lowers the rigidity of the decorative board (C) and improves the familiarity with the laying base surface, but also produces an anchoring effect due to the intrusion of an adhesive, and improves the mounting strength of the decorative board (C). It is effective for

The reference floorboard (A) and the stepped floorboard (B)
Each of the substrates (2) and (5) and the base material (6a) of the surface plate (6) and the decorative plate (C) are made of plywood, laminated wood, medium fiber board, hard fiber board, particle board, orientated One or more kinds of wood boards such as a strand board and a wafer board can be used in combination. A plurality of the same type may be used in combination.

As the decorative material (3) (6b) on the surface, a wooden veneer, a printing paper, a resin-impregnated patterned sheet, or the like is used.

The floor structure according to the present invention using the above-mentioned components is configured as follows.

First, the reference floorboard (A) and the stepped floorboard (B)
Are laid and arranged in a predetermined arrangement on a floor base such as a joist (11) or a concrete floor slab, so that a plurality of the stepped floorboards (B) have a missing step (8). A recess (12) is formed. The concave portion (12) is formed so as to correspond to the arrangement and size of an accent pattern portion such as a mosaic pattern portion to be formed on the floor surface. Also, floor boards (A) and (B)
Mutually, the adjacent members are fitted and joined together by fitting fitting structures (4) and (9) formed on the outer peripheral side surface. For this bonding, an adhesive and a nail are used together.

Then, a plurality of unit decorative plates (C) are fitted in the recessed portion (12) in a predetermined arrangement, and an adhesive, a double-sided adhesive tape, their combination, temporary nails, etc. are arbitrarily selected. It is fixed to the bottom surface of the concave portion (12), that is, the substrate (5) of the missing step portion (8) in the step floor plate (B) by the fixing means. Therefore, an accent pattern such as a mosaic pattern formed by an aggregate of the unit decorative boards (C) is formed at a predetermined portion on the floor surface. In addition, the adjacent decorative panels (C) are mutually adjacent, and the decorative panel (C) and the concave portion (12) are adjacent to each other.
The inner peripheral side surface is formed by joining peripheral side surfaces, which are substantially perpendicular to each other, in a face-to-face contact with each other.

As a specific example, the size of the accent pattern portion due to the combination of the unit decorative board (C) is as follows.
For example, it is formed to have a size of 909 × 909 mm.

A preferred example of a concrete construction procedure in the case of the embodiment shown in FIG. 2 will be described as follows.

First, two rows of reference floorboards (A) and (A) in the upper part of the paper of FIG. 2 are constructed by a common method using an adhesive and a nail. Then, after constructing the left stepped floorboard (B) in the third row, the right floorboard (B) is constructed,
Thereafter, the left and right stepped floorboards (B) in the fourth and fifth rows are sequentially constructed. At this stage, next, the unit decorative board (C) is sequentially attached to the stepped floor board (B) with the urethane-based adhesive and double-sided adhesive tape, etc. on the missing step (8), and
Finally, the reference floorboards (A) in the sixth and seventh rows are sequentially constructed using both an adhesive and nails.

In the above example, the unit decorative panel was installed before the reference floorboards (A) in the sixth and seventh rows were installed.
The reference floorboard (A) and the stepped floorboard (B) may be applied first to form a concave portion, and finally, a decorative panel may be applied sequentially.

[0040]

According to the floor structure of the present invention according to the first aspect, it is possible to freely form an accent pattern portion such as a mosaic pattern over a range of an area extending over a plurality of floor boards. It is possible to cope with the formation of an accent pattern portion occupying an extremely large area without any trouble, and to provide a floor with much better design.

The reference floorboard and the stepped floorboard are mutually
Since these boards are fitted and joined by the fitting and joining structure, even if the floor base is a joist or a concrete floor slab, there is a step between the floor materials. There is no risk of occurrence. In turn, since the bottom surface of the recess formed by the missing step of the stepped floorboard also has no steps, even when the accent pattern portion is constituted by a plurality of divided unit decorative boards,
There is no possibility that a step is generated between the unit decorative boards, and the entire floor surface can be finished in a good flush state.

Furthermore, since the decorative board is formed by butting and joining which can be fitted into the recessed portion from above, the laying of the decorative board for forming the accent pattern can be easily performed.

Further, when the decorative panel is installed over the missing portions of a plurality of stepped floorboards, the decorative panel and the stepped floorboard tend to expand and contract due to a change in temperature and humidity under the floor or a change in temperature and humidity inside the room. Also, mutual movement is suppressed.
For this reason, for example, even if the board of the missing step portion tries to expand and contract, the movement is suppressed by the decorative board, and conversely, if the decorative board and the unit decorative board try to expand and contract, the movement is suppressed by the board of the missing step portion. . Therefore, for changes in temperature and humidity,
It is possible to form an accent pattern portion in which a gap is unlikely to occur.

According to the second aspect of the present invention, in addition to the above effects, it is possible to favorably cope with the formation of an accent pattern having a still larger area.

According to the third aspect of the present invention, in addition to the above-described effects, the notch formed in the lower edge of the peripheral side surface of the decorative plate or the unit decorative plate serves as an adhesive reservoir when the decorative plate or the unit decorative plate is attached with the adhesive. In addition, it is possible to prevent the adhesive from seeping out to the floor surface side.

According to the fourth aspect of the present invention, in addition to the above-described effects, a floor design excellent in design, which is particularly preferable in appearance in the case of a wooden floor, can be constructed.
