Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a floorboard having a floor pattern in which a plurality of rectangular bodies are arranged in a flying geese pattern with their short side seams staggered.

[Prior art and its problems] Conventionally, when forming a floor surface with a pattern in which rectangular bodies are arranged linearly in the vertical direction and joints do not pass linearly in the horizontal direction, a decorative surface is formed. Previously, a method was used in which rectangular plates were pasted one by one to the subfloor, but this method was very time-consuming and involved shifting the joints on the short sides of the rectangular bodies and attaching them to the long sides. In order to obtain a beautiful floor pattern with straight seams, it is necessary to position each rectangular object that makes up the floor in a straight line and attach them to the subfloor one row at a time. If the position of each rectangular body shifts even slightly, the dimensions will not match and open joints will be created, which is unsightly.
There were drawbacks such as the adhesive applied to the base seeping into the joints and damaging the appearance. Therefore, on the upper surface of the back plate 15 of the building board B as shown in Japanese Utility Model Application Publication No. 49-98218, that is, the back board 15 is provided with vertical insertion parts 13 and 14 having stepped holes 11 and 12 at both ends in the vertical direction of the flat board. , a large number of rectangular bodies 16 having the same width are vertically arranged in parallel to form a rectangular body aggregate 17 having the same width as the back plate 15, and the block plate-like aggregate 17 and the back plate 15 are separated by their respective vertical side edges 18, Architectural board B was proposed in which 18', 19, and 19' were arranged so as to form a step drop, but it was made by assembling a large number of rectangular bodies 16 on a back board 15 that is rigid and does not bend easily. because there is,
If the base plate is uneven, the rigid backing board 15 will not be able to adjust to it, and the wrinkles will cause the building board B
This appears in the joints between the building boards B, and the joints between the building boards B create a larger gap than the joints between the rectangular bodies 16 on the surface, which impairs the appearance. This has to be done more carefully than necessary, which is a cause of lowering the construction efficiency.Since the horizontal side edges of the block board assembly 17 are formed with unevenness, the building board B is pushed against the wall from the vertical direction. Since the rectangular body 16 on the front side has to be fitted into the back plate 15 on the back side, there is a construction problem in that it cannot be fitted from diagonally or horizontally near a wall. Since the rectangular bodies 19 are not actually connected to each other, when the back plate 15 bends under the load, the joints between the rectangular bodies 16 will be wide open, spoiling the appearance, and creating uneven surfaces on the surfaces of the rectangular bodies 16. This can cause you to stumble when walking.

There were other drawbacks.

Therefore, although this technology is effective for wall panels, it has not been possible to use it for floor panels.

On the other hand, Japanese Utility Model Application Publication No. 58-132038 discloses a bendable building material in which a plurality of strip-shaped plates are arranged on one side of a flexible sheet, with the strip-shaped plates adjacent to each other being arranged in parallel via real connections. However, in this building material, the actual machining appears only on the long side ends, and furthermore, the short side ends are formed in parallel in a straight line. In such a shape, when a floor is constructed by laying multiple bendable building materials, it is not possible to connect the bendable building materials to each other in the longitudinal direction (towards the ends of the short sides) through real connections. Furthermore, since the joint in that direction only brings the linear ends into contact with each other, the straight joint is exposed, and as the subfloor becomes uneven, it is easy for this joint to become misaligned or level. Further, there are problems in that it spoils the appearance and causes people to trip when walking.

[Object of the invention] The present invention was developed to eliminate such conventional drawbacks, and the object thereof is to have excellent workability and appearance, and to be resistant to unevenness of the subfloor. The purpose is to provide floorboards with good conformability.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides the following: Cutting processing for joining of shapes that can be fitted to each other at both ends in the long side direction and both ends in the short side direction. By sequentially shifting a plurality of elongated rectangular bodies 1, 1, . A step-like side edge is formed at both ends in the short side direction of the body to reveal a cutting part for joining that can fit into each other, and the rectangular bodies are attached to the back side to make it bendable. The floor plate A is formed by integrally forming a sheet-like material.

; is adopted as a technical means.

[Function] This floorboard A is a rectangular body whose ends in the short side direction are formed into a step shape, and are integrated in a flying geese pattern.
When constructing the floor plates A, A, etc. on the base, they can be fitted not only in the vertical direction but also in the diagonal direction and in the direction parallel to the short side, which greatly improves the workability.

Since the rectangular bodies 1, 1... are connected by actual bonding, when they are integrated or installed on the subfloor, the adhesive present on the back side may ooze out from the joints to the surface, resulting in an unfavorable appearance. It will not be damaged.

Rectangular bodies 1, 1... can be freely bent along each long side in the continuous parts, adapt well to the unevenness of the base, and the joint gaps due to the unevenness are dispersed in each continuous part. It is.

Moreover, since the adjacent rectangular bodies 1 and 1 are actually connected, even if the floorboard A, which is a collection of rectangular bodies 1, bends along the unevenness of the base, the joints will not open wide and a beautiful finish will be achieved. Furthermore, there is no difference in level between the surfaces of the rectangular bodies 1, 1....

The joints between floorboards A and A are connected in a flying geese pattern both vertically and horizontally through real connections.
Even if joint gaps occur due to the unevenness of the base, they can be evenly distributed over the entire area, creating a floor surface that is flat and free of joint gaps throughout.

In this way, the floorboards A... can efficiently construct a floor surface that is flat over the entire area and has no joint gaps.

[Example] An example of the present invention will be shown. To explain the drawings, reference numeral 1 denotes an elongated rectangular body made of a wooden board, and there are holes for joining a male fruit 2 and a female fruit 3 that fit into each other at both ends in the long side direction and both ends in the short side direction. It has been machined. Further, the rectangular body 1 is made of a laminated material of thin plates, and a decorative layer 5 made of a synthetic resin impregnated layer is integrally provided on the surface layer.

By connecting a plurality of pieces of the rectangular body 1 with their long sides a in contact with each other by a real connection, and sequentially shifting the connecting positions by an appropriate dimension e in the long side direction, the short sides of the rectangular body A bendable sheet-like material 8 that forms step-like side edges in which joining cutting parts shaped to be able to fit into each other are exposed at both ends of the direction, and that is adhered to the entire surface or a portion of the back surface. As one body,
It constitutes a floor plate A.

In FIG. 3, the sheet material 8 is, for example, a foamed plastic sheet. Note that the number of rectangular bodies 1 to be connected is not particularly limited to two or more, but the rectangular body 1
When the size of the paper is 50 x 300 mm, it is preferable to use 4 to 6 sheets for ease of handling.

If a floor is constructed using the above floorboard A, the short sides b of the rectangular bodies 1 on the floorboard A will be joined together, and the rectangular bodies 1 will be arranged so that they are lined up, and each floorboard A will be successively installed. By moving the rectangular objects, a floor pattern is created in which the rectangular objects are arranged.

In addition, in the above embodiment, since the integration is by the actual joint and the sheet-like material 8, the rectangular body 1 can be easily separated by cutting the sheet-like material 8 along the real joint, and the floor shape can be adjusted during construction. This means that the length of the short side of the floorboard A can be adjusted as appropriate.

[Effects] As described above, the floorboard of the present invention is made up of a plurality of sheets, each of which has been cut for joining into shapes that can be fitted to each other at both ends in the long side direction and both ends in the short side direction. A rectangular body with an elongated shape is connected to an adjacent rectangular body by an appropriate dimension in the long side direction and connected in a real connection, so that both ends of the rectangular body in the short side direction can fit into each other. A step-like side edge is formed to expose a cutting part for joining, and the rectangular bodies are integrally formed by a bendable sheet-like material attached to the back surface, so that the floor surface When constructing a pattern, it is now possible to construct a floorboard that is a collection of rectangular bodies, and the joints in the short side direction can be shifted from each other without having to position each rectangular body one by one as in the past, making it easy to Not only can the construction be carried out, but the joint lines of the short sides of the rectangular bodies always appear offset, and the floor pattern of the joints, which are arranged offset throughout and have a high decorative and design effect, is revealed, and the joint Sometimes, both edges of the short side of the rectangular body are step-like,
It can be fitted not only vertically but also diagonally or parallel to the short side, making it easy to install in narrow spaces or near walls.

In addition, since the rectangular bodies are integrated with a sheet-like material, even if there is an uneven surface on the subfloor to be constructed, the adjacent rectangular bodies will bend from their connected parts due to the sheet-like material, resulting in uneven surfaces. It has the advantage of being familiar with
Furthermore, because the joint gaps due to unevenness are dispersed in each connected part, and because adjacent rectangular bodies are actually connected, large and uneven joint openings occur at the joints between floorboards and the joints between rectangular bodies. This results in a uniform joint as a whole, and a beautiful finish with no level difference between the surfaces of the rectangular body.

Since a smooth floor surface can be formed with such simple construction, there is no need to carry out base construction with excessive precision, and the process from foundation construction to floor surface formation can be performed very efficiently.

Furthermore, since each of the plurality of rectangular bodies has a cutting process applied to the peripheral side surfaces thereof for joining, when the male and female seeds formed thereby are joined by fitting, the base Adhesive does not ooze out on the surface of the floorboard due to the unevenness of the floorboards, and large joints do not open due to bending, and floor rumbling etc. can be prevented and a beautiful finish can be achieved.

In addition, when the rectangular body is formed from a laminated material of thin plates,
Since it does not warp even under the influence of humidity, it has sufficient adhesion to the base and there is no risk of peeling.
In addition, stable floorboards are obtained that do not expand or contract due to the effects of humidity, so there are no gaps due to dimensional errors, no dirt or dust accumulates, and the joints are hygienic and beautiful, and the joints due to the extension of the floorboards Since this prevents the table or chair from lifting up, there is no risk of the legs getting caught on the edge of the floorboard and causing damage when moving the table or chair.

Furthermore, when the decorative layer on the surface of each rectangular body that makes up the floorboard is made of synthetic resin-injected wooden boards, it has excellent abrasion resistance, stain resistance, and water resistance, and when tables and chairs are placed. , will not be dented or damaged by the pressing force of the legs, and even if it gets dirty, it can be easily wiped off.Also, since it hardly absorbs water from the surface side, it is resistant to rot, and the surface grain pattern etc. It is possible to obtain a highly durable floorboard with a well-maintained decorative surface. In addition, it has many excellent properties as a floorboard, such as the upper corner portions not being damaged during transportation and handling, and the joints being strengthened.
