Description

[Detailed description of the device]

[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 and FIG. 5 show examples of floor laying of floor panels. The former prepares a panel unit PU consisting of an assembly of nine floor panels 1S, which are fixed by adhering tile carpets Cn of a predetermined size (1 side A = 50 cm) on the surface in advance, and this panel unit PU is An appropriate gap S0 is formed at the carpet joint portion, and the carpet unit is spread on the floor surface in units. On the other hand, in the latter, a flat rectangular floor panel 1L (1 side B = 25 cm) slightly larger than the former is laid on the floor with the panel sides abutting each other, and then the tile carpet C is placed on top of it. Is laid. Comparing the two cases, in the latter case, the carpet C is simply overlaid after the floor panel 1L is laid vertically and horizontally, which is advantageous in terms of simplicity of construction and construction cost.

[0004]

[Problems to be solved by the device]

 However, in the case of adopting the panel laying method of the type shown in FIG. 5, a free joining structure in which the adjacent floor panels 1L are not fixed to each other and the floor panels 1L and the tile carpet C laid thereon are mutually fixed. Therefore, when an external force is applied to the floor panel 1L, there is a risk that the panels will be easily displaced from each other.

Further, in this construction method, since the side portions of the adjacent floor panels 1L are closely adhered to each other without a gap, when the floor panel 1L is dimensionally changed due to thermal expansion due to a change in room temperature, the panels are There is a problem that troubles such as floating are likely to occur.

In view of the above problems, the present invention provides a floor panel in which countermeasures for effectively preventing the displacement between the panels and the thermal deformation due to the room temperature change are provided.

[0007]

[Means for Solving the Problems]

 The floor panel according to the present invention is a flat rectangular panel laid on the floor with the side portions abutting each other, and the convex portion and the tip portion of the convex portion are provided at symmetrical positions of the respective side portions. It is provided with a recess having a fitting shape.

[0008]

[Action]

 In this floor panel, when the side parts are laid on each other with the side parts abutting against each other, the convex part provided on one adjacent panel side part fits into the concave part provided on the other panel side part. Therefore, it is possible to prevent the panels from being displaced from each other. Also, by fitting only the tip of the convex portion into the concave portion, an appropriate gap is formed between the adjacent panel side portions and the dimensional change due to thermal expansion of each floor panel is fitted into the concave portion. Can be absorbed by local deformation of the part.

[0009]

【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 quadrangular (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 sides, 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. The mesh structure is provided with diagonal ribs 2C and 2C that are installed by diagonally crossing between the supporting legs 3 and 3, and the upper surface side is provided in each opening surrounded by the lattice ribs 2B and 2B. In the vicinity, it is also provided with a reinforcing means for connecting the reinforcing ribs 2D in a cross shape.

[0012] Then, in the floor panel 1, the convex portion 4 having a chevron cross section and the tip end portion of the convex portion 4 are fitted to the side portions 2A of the panel body 2 at symmetrical positions with respect to the center of the panel. A recess 5 having a substantially trapezoidal cross section is provided. The convex portions 4 and the concave portions 5 are provided alternately in the circumferential direction of the panel body 2.

In addition, in FIG. 1, reference numeral 6 denotes a cutout portion that forms a cord conduction hole for pulling out a wiring cord from under the panel floor. Each side portion 2A of the panel body 2 has a semicircular shape at a plurality of symmetrical positions. It is provided in.

FIG. 2 shows an assembled state in which a plurality of floor panels 1 provided with the convex portions 4 and the concave portions 5 are laid on the floor surface with their side portions 2A in contact with each other. That is, if the floor panel 1 is used, when the panel side portions 2A are brought into contact with each other at the aligned position and arranged vertically and horizontally, a proper gap S between the panel side portions 2A and 2A is formed, As shown in FIG. 4, the tips 4A of the protrusions 4 provided on one of the panel sides 2A adjacent to each other are fitted into the recesses 5 provided at the corresponding positions on the other panel side 2A to be engaged with each other. Will be.

That is, by realizing the engagement state of the convex portion 4 and the concave portion 5 in which the gap S is left between the panel side portions 2A and 2A, it is possible to reliably prevent the displacement between the panels. Further, the dimensional change due to the thermal expansion of the floor panel 1 can be absorbed by the local deformation of the convex portion 4 in which the tip portion 4A fits in the concave portion 5.

The cross-sectional shapes of the convex portions 4 and the concave portions 5 provided on each side portion 2A of the floor panel 1 and the detailed design conditions such as the height or the depth dimension can be appropriately selected. Further, if necessary, it is possible to provide a plurality of pairs of the convex portions 4 and the concave portions 5 at symmetrical positions of each side portion 2A.

[0017]

[Effect of the device]

 As described above, in the floor panel of the present invention, by providing the convex portion and the concave portion having the shape in which the tip end portion of the convex portion is fitted at the symmetrical positions of the respective side portions, the panel side portions are brought into contact with each other. It is possible to accurately solve the problems such as the mutual displacement of the panels and the rise of the panels due to thermal expansion when the method of laying the tile carpet on the floor after laying it on the floor surface is adopted.
