Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a free access type floor board used for forming another floor surface on a foundation floor surface in an OA room or a general office room.

[0002]

BACKGROUND OF THE INVENTION OA room or the like, to make room for wiring and the like under the floor, sometimes the floor dual structure. This required that the floor plate to be used in the case, even if there is uneven surface of the uneven underlying floor, each floor plate to be laid is that no rattle.

[0003] Conventionally, the square plate has been used in this floor, because it required a great deal of time to adjust during construction, in recent years, have become so that triangle plate is used. According to the triangle plate, since the three-point support is possible, easily can Rukoto to follow the floor, but a simple adjustment during construction, storage, transportation, none of the construction, the square plate compared to non
A stool and difficult, and the support point of each corner of the triangular plate to become an acute angle, there is a disadvantage that the strength is insufficient. Therefore, yet quadrangle, development floorboards are desired to have the characteristics of a triangle.

As a solution to the problem, Japanese Patent Laid-Open No. 57-1807.
The 59 discloses, in a mounting plate is provided in the corner lower surface of the triangular plate is supported an adjuster, connected triangular plate, it carried out in the mounting board such as a carpet, also, JP 63-70763
No. In Japanese, it is disclosed that form either the topsheet or the bottom sheet of the floor panels formed by two steel plates in the top sheet and bottom sheet triangle, the other as coupling member of the rectangle.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the invention described in Japanese Patent No. 0759, handling as a rectangular floor plate requires simultaneous mounting of the facing plate, which requires a lot of labor to handle.

In the invention described in JP-A-63-70763, since two steel plates are used , the weight is increased and the cost is increased.

[0007] The present invention has been made in view of such problems the prior art has, in correspondence with the uneven surface of the floor, there is no backlash, and it without causing insufficient strength, moreover, transportation,
The purpose is to provide a lightweight, inexpensive floorboard that is easy to store, construct, and handle.

[0008]

In order to achieve the above object, one steel plate is bent to form a right triangle, and
It has a bent lower edge on the side and below this bent lower edge.
A pair of triangular plates with flanges at the ends facing the apex direction
The bottom edges of the
The edges are joined together to form a square plate, and this square plate
Is characterized in that support legs are provided on the lower surface of each vertex .

The bending angle of the lower edge of the bend is several degrees from a right angle.
A large obtuse angle is good.

On the upper surface of the triangular plate, parallel to the hypotenuse or
Rukoto providing a dent conditions for strengthening at right angles also.

[0011]

When the floor board of the present invention is supported on the base floor surface by the support legs, the bent lower edge of the triangular board can be bent upward and downward with the joint at the lower end as a fulcrum. even if Furiku portion, floorboards follows the uneven surface, rattling of the floorboards is prevented, also it becomes simple adjustment during construction.

[0012] floor itself, as the original one triangle plate pair which is bent to form a steel plate and is formed in a square, transportation, storage, construction, easy to handle, yet lightweight in that Do and inexpensive.

[0013] In addition, the triangular plate bending under the edge of it and the polymerization state
Ttei Runode, the sufficient to strength.

The angle of the bent lower edge is a few degrees larger than a right angle.
With a blunt angle, the triangular plates easily bend in the vertical direction.
Ur so now, the follow-up for non-land portion of the base floor surface
Is better (claim 2).

The strength of the floor plate is further strengthened by providing a reinforcing recessed line parallel or at right angles to the hypotenuse on the upper surface of the triangular plate (claim 3).

[0016]

Embodiments of the present invention will be described below with reference to the drawings. Figure 1 is a planar surface view of the floor of the present invention, FIG. 2, bottom view of the floor of the present invention, FIG. 3, A-A line enlarged longitudinal sectional <br/> view of FIG. 1, FIG. 4, It is a figure similar to FIG. 3 which shows the state which supported the floor board of this invention on the foundation floor surface which has a non-planar part with the support leg .

The floor board (1) of the present invention comprises a pair of triangular boards (1
are made form in a) (1b). Triangular plate (1a) (1b) is a single <br/> steel, by bending by a press, it is <br/> formed isosceles right triangle. Hypotenuse of each triangle plates (1a) (1b) is downwardly Te bent Gerare, has a bending lower edge (5), and bent
At the lower end of the lower edge of the barb (5), there is a flap facing inward
The lunge (8) is lined up.

The bending angle (6) of the bending lower edge (5) is
Tight pair of triangular plates Oblique sides of (1a) (1b) when made to face
As against, may be a right angle, as shown in FIG. 3, it is preferable to several degrees greater obtuse than a right angle.

(4)By joining withA pair of triangular plates (1
a) (1b)Form a square plate and attach it to the bottom of each vertex.
The floor board of the present invention can be prepared by attaching appropriate supporting legs (2).
(1) is formed.

In this way, the bent lower edge (5) has its lower end.
Since they are joined together, they are deformed and the triangular plate (1a) (1
b) can be slightly bent in the vertical direction.

On the upper surface of the floor plate (1), there are recessed lines (7) for reinforcement.
There is provided in parallel or perpendicularly with its diagonal.

Next, the operation will be described. As shown in FIG. 4, when the floor board (1) is supported on the foundation floor surface (3) by the support legs (2), the bent lower edges of the triangular boards (1a) (1b) are loaded depending on the load.
(5) is deformed with the joint at its lower end as a fulcrum, forming a triangle
The plates (1a) and (1b) can be bent upward and downward . Therefore
The floor plate (1), even if there is Furiku section underlying the floor (3), good
Can follow appropriately. Also the floor plate (1) is not rattle, and can take no troublesome adjustment during construction.

The bending angle (6) of the bending lower edge (5) is shown in FIG.
As shown in, if the obtuse angle is a few degrees larger than the right angle , the floorboard
The ability of (1) to follow the uneven portion of the foundation floor (3) is further improved.

The floorboards (1), because it is formed in the square a pair of triangular plate (1a) (1b) to the original, transportation, storage, construction,
Easy handling der Rubakari or, in the triangular plate (1a) (1b) joint between, the bent portion lower edge (5) (5) is a polymerized state
Therefore, the strength is also sufficient, and each three
Since the rectangular plates (1a) and (1b) are composed of one steel plate, they are lightweight and inexpensive.

[0025]

In the claims 1 floor according to the present invention, the bent lower edge of the triangular floorboards bendable vertically junction as a fulcrum
Oh Runode, also sufficiently follow if there is Furiku part in the foundation floor
Te, rattling is prevented, and adjustment during construction is simple der
It

[0026] In addition, because it is formed in a square on the basis of a pair of triangular plate which is formed by folding a sheet of steel, transportation, storage, construction, it is easy to handle, moreover, lightweight and inexpensive thing as that Do not. Furthermore, in the junction of the triangular plate, the bending lower edge is in the polymerized state, lifting sufficient strength
You can put it on.

In the floor board of the second aspect, the bent lower edge portion can be more easily bent up and down, and the followability to the uneven portion of the foundation floor surface can be further improved.

As described in claim 3 , when the concave line for reinforcement is appropriately provided on the upper surface, the strength of the floor board is further enhanced.
