Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor member for forming a wooden floor surface such as a flooring floor of a general house or a store, or a free access floor of a company or office.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, a floor member that forms a flooring has conventionally been provided with a convex portion 101 on one side and a concave portion on the other side on left and right side edges on the long side of a plate material 100 having a flooring surface. A real persimmon part to be 102 is provided, and by adhering the real persimmon part, the adjacent plate materials 100 and 100 are joined to each other and a large number are spread on the floor base 200 to form a wooden floor surface 300. . The convex portion 101 and the concave portion 102 are formed in a rectangular cross section as shown in the drawing, and are adjacent plate materials.
Unless one or both of 100 and 100 are moved in the horizontal direction, engagement and disengagement (engagement and disengagement) of the two, that is, joining and separation of floor members, is prevented.

[0003]

The conventional floor member described above is
As mentioned above, unless the plate 100 is moved in the horizontal direction, the floor members are not joined and separated from each other.
When laying a large number on the 200, it was necessary to hit them one by one with hail, cutting, etc. in order to bring the perforations into close contact. Further, in order to install the plate materials 100 with good stability against the warp absorption or the undulation of the floor base material, each plate material 100 is fixed by an appropriate fixing means such as nailing or bonding, and the floor base material 200 is fixed.
It was necessary to place it on top, and the laying work was troublesome and required skill. In addition, after forming a flooring floor by laying it on the floor base 200, unless it is sequentially removed from the plate materials located at the outer edge portion of the flooring floor, the adjacent plate materials 100, 100 cannot be separated from each other. When part of the flooring floor is repaired, it is necessary to separate the floor member 100 that does not need to be replaced.Furthermore, each plate material 100 is fixed to the floor base by nailing or bonding as described above. It takes a lot of work to peel off the floor member 100 in order to change the pattern or the like.

The present invention has been made in view of the above-mentioned conventional circumstances, and an object of the present invention is to easily join and separate floor members to each other and to fix them by nailing or bonding. The board material can be placed on the floor substrate with good stability without requiring, and the work of laying it on the floor substrate and the removal after laying it can be done easily, not only for flooring floor formation, but also free access It is to provide a novel floor member that is also useful for floor formation.

[0005]

In order to achieve the above object, in the floor member of the present invention, the convex portion and the concave portion are formed from an inclined surface or a curved surface which can be engaged and disengaged when the plate material is inclined. Along with the formation, a plurality of grooves extending in a direction orthogonal to the longitudinal direction of the plate material are formed at appropriate intervals on the back surface of the plate material, and a sheet having a desired elasticity is attached to the back surface of the plate material. Here, the convex portion and the concave portion formed from an inclined surface or a curved surface that can engage and disengage the plate material in the inclined state are, for example, a convex portion and a concave portion formed in a substantially triangular cross section or a substantially semicircular cross section. Say.

According to the above construction, after the actual tongue portion of the one floor member placed on the floor base is engaged with the actual tongue portion of the other floor member from diagonally above, If the other floor member is placed on the floor base, both floor members are joined. Further, the large number of grooves on the back surface of the plate material suppress the warp of the plate material and allow the plate material to be deformed corresponding to the undulation of the floor base. At the same time, the sheet attached to the back surface of the plate prevents the strength of the plate from decreasing due to the provision of the large number of grooves, suppresses the warp of the plate, and deforms in response to the undulations of the floor substrate to absorb the undulations. However, due to the synergistic effect of the large number of grooves and the sheet, it is possible to minimize the warpage of the plate material,
It is possible to greatly improve the stability of the plate material with respect to the floor base. Therefore, when laying a large number of floor members on the floor base, it is not necessary to hit each one with a hail, a cut or the like to join the adjacent floor members together, and a fixing means such as nailing or bonding is used. Without using it, one floor member placed on the floor base is engaged with the other floor member diagonally from above, and then the other floor member is simply placed on the floor base by repeating the work. It is possible to form a wooden floor surface with various operations.

[0007] Further, if the left or right side edge of the long side of any floor member of the wooden floor formed as described above is lifted up, the adjacent floors that engage with the side edge are joined together. The side edges of the members are also lifted upward to disengage the two floor members, and the two floor members can be removed from the wooden floor surface (see FIG. 5). In addition, the two floor members removed in this manner have one of the left and right sides of the floor members interlocked with each other within the opening of the wooden floor surface where both floor members have been removed. In a state in which the other actual perforated part is engaged with the actual perforated part of the floor member placed on the floor base,
By inclining both floor members in a C shape in side view and pushing down both floor members from that state, both floor members and the floor member on the floor base adjacent to both floor members are joined to each other, and at the same time, in the opening. Both floor members are fitted and the wooden floor surface is restored.
