Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a floor-standing floor panel that is placed directly on a foundation floor.

(Prior art) Laying floor panels are usually made of synthetic resin, and the face plate and the legs are integrally formed, so that the manufacturing cost is low,
Because it is directly affected by unevenness, it is used on the premise that the foundation floor has little undulation.

(Problem to be Solved by the Invention) When the installed device is heavy, a portion having a long span between legs may be largely bent, and a space for cable wiring having a predetermined height cannot be secured.

To prevent this, it is also proposed to increase the thickness of the face plate, but this is not preferable because the space for cable wiring becomes narrower as the thickness increases.

Further, usually, the boundary between the room and the room wall forms a floating floor with a dedicated panel called a border panel in which a particle board is cut in a corresponding area.

However, the particle board is not reliable in terms of strength, and it is necessary to use a thicker board than other panels, and it is not possible to secure sufficient cable wiring space. It must be carried in and management is required.

The present invention has been made in view of the above-mentioned conventional circumstances, and the purpose of the present invention is to newly install legs at desired locations as needed,
It is an object of the present invention to prevent bending deformation and to enable use as a border panel.

(Means for Solving the Problems) The technical means taken in order to achieve the above object is as described in claim 1, in which a plurality of small block bodies having legs at corners of a face plate having an isosceles triangle having a right angle in plan view are provided. Long side end faces, short side end faces are gathered in close proximity to each other to form a panel body, and peripheral ribs are formed on the back surface along each side of each small block body constituting the panel body, The gist is that a large number of insertion recesses for fitting and holding additional legs are formed in the lower surface of the peripheral rib along the longitudinal direction of the peripheral rib.

Claim 2 forms peripheral ribs on the back surface along each side of the panel body having legs at the corners of the face plate having a rectangular shape in plan view, and grid-like ribs are continuously provided between the peripheral ribs. The gist of the present invention is that a large number of insertion recesses for fitting and holding additional legs on the lower surfaces of the peripheral ribs and the grid-like ribs are formed along the longitudinal direction of the peripheral ribs and the grid-like ribs.

(Function) According to the above-mentioned technical means, when preventing bending deformation of the face plate portion due to concentrated stress or when compensating for a shortage of a leg due to a cutting action on site, the extension leg can be mounted so as not to move to an optimum position. . In spite of providing a large number of insertion concave portions for the additional legs, the concave portions are formed with the peripheral ribs and the lattice-shaped ribs, so that the strength of the panel main body can be prevented from lowering.

(Effects of the Invention) As described above, the present invention forms a peripheral rib on the back surface along each side of the panel body, and inserts an insertion recess for inserting and holding the upper end of the additional leg into the peripheral rib. Because of the many concaves along the peripheral ribs and the grid-like ribs, when avoiding the partial concentration of the load of the installed equipment, it was cut on site to an area equivalent to the floating floor at the boundary with the room wall At times, the extension legs can be mounted so as not to move to the optimum positions matching those conditions.

Further, since the peripheral ribs on the back surface provided along each side of the panel main body and the lattice-shaped ribs connecting the peripheral ribs are provided with the insertion concave portions of the additional legs, the strength of the panel main body may be reduced. And a predetermined durability can be maintained.

(Example) Next, the Example of this invention is described based on drawing.

FIGS. 1 to 4 show the floor panel (A) with an isosceles length of 250 m.
A small block body (a ₁ ′) 8 in which a right-angled isosceles triangular face plate (1) of about m and a corner leg (2) of the same height are integrally formed of a synthetic resin material (for example, polypropylene or the like). As shown in the figure, a panel body (a ₁ ) formed by assembling the long side end faces and the short side end faces in close proximity to each other, and a flexible polypropylene film (a ₂ ) fixed to the surface thereof And the like are shown.

This embodiment is the approach portion (3), i.e. takeout cable any size by wrapping polypropylene film on 3~4mm clearance of about the small block body from (a ₂₎ parts (a ₁ ') is open In addition, each small block body (a ₁ ′) is supported at three points, so that the small block body (a ₁ ′) has the effect of being able to contact the ground without any backlash regardless of unevenness of the base floor (B).

This floor panel (A) has additional legs (6) on its back.
Has a concave portion for insertion (a ₃ ).

In each small block body (a ₁ ′), the insertion recess (a ₃ ) is provided with a reinforcing rib (5) of a face plate (1) composed of a front plate (1 ′) and a reinforcing rib (5) integrally formed on the back surface. ).

The reinforcing ribs (5) include a peripheral rib (5a) vertically extending along the back surface of each side of the surface plate (1 ') and a grid-like rib (5b) vertically suspended between the peripheral ribs (5a). The insertion rib (a ₃ ) is formed in the peripheral rib (5a).

The insertion concave portion (a ₃ ) is a substantially circular concave portion as shown in detail in FIG. 1. The peripheral concave portion (5a) extends over the entire length of the peripheral rib (5a) in a partially connected state. (5a) Many are recessed from the lower surface.

Thus, when used as a panel for borders, as shown in FIGS. 3 and 4, after cutting to a predetermined area, the cut block body (a) is used to correct instability.
The upper end of the additional leg (6) is fitted into the insertion concave portion (a ₃ ) of the desired portion so that ₁ ″) can be supported at three points or more.

The extension leg (6) is provided at the upper end of the large portion (6a) with an insertion recess (a).
₃ ) A small-diameter portion (6b) that fits into the small-diameter portion (6b)
Is fitted in the insertion recess (a ₃ ), and the large portion (6
a) The length is determined such that the lower end is located at the same height level as the lower end of the corner leg (2).

Therefore, regardless of the size of the area of the border portion, the floating floor (C) of the border portion can be constituted by using the cut blocks (a ₁ ″)...

Further, when the normal partial heavy in use is Nouketamawa, by supporting the front surface plate (1 ') portion in the insertion recess extension legs fitted to (a ₃₎ (6) , Just reinforce.

Since the small-diameter portion (6b) at the upper end of the additional leg (6) is fitted into the insertion concave portion (a ₃ ) so that the additional leg (6) is immovably attached, the additional leg is added due to vibration such as walking or earthquake. Legs (6)
Does not move and stably supports the face plate (1) at the extension position.

The present invention is applicable not only to the floor panel of the subdivision type but also to the floor panel of which the face plate is formed of a single plate of 500 mm × 500 mm square.

In this case, as shown in FIG. 5, a leg (2) is provided at a corner of a face plate (1) having a rectangular shape in a plan view to provide a panel body (a).
₁₎ is formed, the panel body (a ₁₎ together with integrally formed peripheral ribs (5a) on the back surface along each side, grid-like ribs over between the peripheral ribs (5a) (5b) Is integrally molded,
This is dealt with by forming insertion recesses (a ₃ ) of additional legs (not shown) in the same manner as in the above embodiment over the entire area of the ribs (5a) and (5b).
