[0001]

[Industrial applications]

 The present invention relates to a floor panel for laying on a floor surface to form a double floor.

[0002]

[Prior Art]

 With the recent automation of offices, as interiors of OA floors where high-density arrangement of OA equipment is planned, floor panels are spread over the floor surface to form a double floor, and indoor wiring required for the space under the panel floor. Is being stored.

FIG. 4 illustrates an example of a current floor panel laying method. In this construction method, for example, a flat rectangular floor panel 1 having a side B of 25 cm is laid on the floor with the panel sides abutting each other, and then the tile carpet C is laid on the floor panel 1. Since the floor panel 1 is laid vertically and horizontally, and then the carpet C is simply overlaid, it is advantageous in terms of simplicity of construction and construction cost.

[0004]

[Problems to be solved by the device]

 However, even when this type of panel laying method is adopted, there are some problems to be improved in the following points.

The first problem is that, as shown by the arrow in FIG. 4, the floor panel 1 laid on the floor surface portion where the concentrated load F is locally applied has a rafter on the back side. It is necessary to add reinforcement means, but at present, this reinforcement work is complicated.

The second problem is that, depending on the size and layout of the floor, as shown by the chain double-dashed line in FIG. There are quite a few cases where 1H is required (which is called a deformed panel), and in the current method of assembling a specially made end unit to this part, it is necessary to prepare units of various sizes and combine them on-site. One of the reasons is that the construction is complicated and the cost is high.

In view of the above-mentioned problems of the present situation, the present invention provides a floor panel improved so that local reinforcement and adjustment / assembling work of a deformed panel can be easily performed.

[0008]

[Means for Solving the Problems]

 The floor panel according to the present invention is a flat rectangular panel laid on the floor with the sides abutting each other, and the back side of the panel body is formed by a lattice having openings of equal size. It consists of things.

[0009]

[Action]

 If this floor panel is used, local reinforcement of the panel and adjustment / assembling work of the odd-shaped panel can be carried out conveniently only by preparing one kind of auxiliary leg to be inserted into the opening of the panel body in advance. . That is, when local reinforcement of the panel is required, auxiliary legs should be inserted from the back side to the opening of the panel body at the site where the concentrated load acts. After cutting the floor panel to the desired size, it is sufficient to add auxiliary legs to the corners on the cutting side in the same manner as above.

[0010]

【Example】

 1A and 1B show an embodiment of a floor panel according to the present invention.

The floor panel 1 is formed by including a flat panel quadrilateral (square) panel body 2 and four hollow support legs 3 projecting downward from four corners of the panel body 2.

The panel body 2 includes outer frame ribs 2A having four sides forming panel side portions, and grid ribs 2B and 2B that are provided at equal intervals between the outer frame ribs 2A and 2A facing each other and are orthogonal to each other. It is formed of a mesh structure provided with diagonal ribs 2C and 2C which are diagonally crossed between the supporting legs 3 and 3 and are installed on the panel surface side, and each opening surrounded by lattice ribs 2B and 2B. The part 4 is provided with a reinforcing means for connecting the reinforcing ribs 2D in a cross shape near the surface side.

Thus, in this floor panel 1, the back surface side of the panel body 2 is formed by a lattice body having a large number of square openings 4 of equal size. The peripheral wall portion of each opening 4 is slightly tapered so as to expand downward as seen in FIG. 1 (B).

As shown in FIG. 1 (B), the floor panel 1 is provided with auxiliary legs 5 of a certain size as attachments. The auxiliary leg 5 is attachable / detachable to / from any of the rectangular openings 4 formed to have the same size by inserting and inserting the insertion head 5a having a shape corresponding to the opening shape from the back side of the panel body 2. When the insertion head 5a is fitted into any one of the square openings 4, the heights of the lower end of the auxiliary leg 5 and the lower end of the panel-integrated leg 3 are aligned with each other. It is like this.

In addition, in the floor panel 1 shown in FIG. 1, a pair of convex portions 6 having a chevron-shaped cross section are provided at symmetrical positions of the side portions 2 A of the panel body 2 to prevent the panels from being displaced from each other. A convex portion 6 is provided with a concave portion 7 having a substantially trapezoidal cross section into which the tip portion of the convex portion 6 fits, and a cord conducting hole for pulling out wiring cords from under the floor of the panel is formed at the symmetrical position of each side portion 2A. A semi-circular cutout 8 is provided.

2 and 3 show an example of use in which the auxiliary leg 5 is combined with the floor panel 1. FIG. 2 exemplifies a case where the auxiliary leg 5 is additionally inserted from the rear surface side into the rectangular opening 4 at the portion where the concentrated load F acts when local reinforcement of the panel 1 is required, and FIG. When the deformed panel 1H is needed, first, the standard size floor panel 1 is cut into a desired size (cutting surface K), and then the square opening 4 is opened at the corner on the cutting side. Similarly, the case where the auxiliary legs 5 and 5 are added is shown as an example.

As can be understood from the above-described usage example, the floor panel 1 having a lattice structure not only allows the panel body 2 to be reduced in weight as the panel body 2 becomes hollow, but also reduces the weight of the panel body 2. By inserting one kind of auxiliary leg 5 prepared as an attachment into the square openings 4 of equal size formed on the back side, it is necessary for local reinforcement necessary for concentrated load parts and on the wall side. Compared with the conventional construction method, the adjustment and assembly work of the odd-shaped panel is very simple, and the convenience that the special unit is not used at all can be achieved.

The shape, number, distribution, etc. of the openings 4 formed in the panel body 2 can be freely changed. Further, the opening 4 need only be formed on the back side of the panel body 2 into which the auxiliary leg 5 is inserted, and the front side does not necessarily have a lattice structure.

[0019]

[Effect of the device]

 As described above, in the floor panel of the present invention, the back side of the panel body is formed of the lattice body having the openings of equal size, so that one kind of auxiliary leg that is attached to the opening as an attachment is provided. If it is prepared, the local reinforcement of the panel and the adjustment / assembling work of the odd-shaped panel, which are necessary for laying the panel on the floor, will be improved easily and at low cost.
