Abstract

PROBLEM TO BE SOLVED: To stably stack floor level adjustment boards with a simple constitution by interposing between equipment and an installation floor surface, forming a plurality of recesses/projections of same shape in the upper and lower faces, and mating upper projections with lower recesses and upper recesses with lower projections, respectively. SOLUTION: When a plurality of floor level adjustment boards 11 are stacked together, hill parts 12 on the upper face of the floor level adjustment board in the bottom side are mated with valley parts 13 on the bottom face of the floor level adjustment board in the upper side. In this case, when a waveform is too shallow or a pitch is too large, the engagement between the hill parts and the valley parts becomes thin so as to be useless for preventing deviation. When the floor level adjustment boards 11 are installed in the bottom side of a skid, they are so arranged that their longitudinal directions are brought in contact in such a state as crossing at right angles with each other. The extension directions of the hill parts 12 and the valley parts 13 of the level adjustment boards 11 cross with each other so as to prevent the deviation, even if the laminated floor level adjustment boards 11 are deviated in the extension directions of the hill parts 12 and the valley parts 13.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor level adjusting plate which is interposed between a device such as a prefabricated refrigerator and a floor on which the device is to be installed, so as to level the device, and a method for installing the same.

2. Description of the Related Art Conventionally, for example, in a prefabricated refrigerator 1 as shown in FIG. 1, when the floor FL on which it is installed is uneven, or when the floor FL is inclined as shown in FIG. However, the prefabricated refrigerator 1 cannot be stably installed in a horizontal state. Therefore, conventionally, as shown in FIG. 2, one or two or more floor level adjusting plates (indicated by P in FIG. 2) are stacked between the prefabricated refrigerator P and the skid 2 and are interposed at predetermined intervals. And took the horizontal level.

[0003] Here, 3 is a ceiling panel of the prefabricated refrigerator 1, 4 is a corner panel, 6 is a side panel, 7 is a floor panel, and 8 is a door. The skid 2 is a member that is attached to the lower surface of the floor panel 7 and abuts on the floor surface FL, and is made of steel.

[0004]

Next, a conventional floor level adjusting plate 101 (indicated by P in FIG. 2) is shown in FIGS.
5 will be described. The conventional floor level adjusting plate 101 is made of a rectangular thin steel plate as shown in FIG. 9 and its surface is a smooth flat surface. When a plurality of sheets are stacked and used, as shown in FIG.
02 and the like are temporarily fixed. However, since the surface is inevitably flat, it is easily shifted as shown in FIG. 11 due to vibration during use, and the stability is deteriorated.

Therefore, it is conceivable that the upper and lower surfaces of the floor level adjusting plate 101 are corrugated as shown in FIG. However, in this case as well, if the wave shapes of the upper surface and the lower surface are made symmetrical as shown in FIG. 13, the peak portion 103 and the valley portion 104 of the waveform come to a position where the upper surface and the lower surface face each other.

[0006] Then, when these are piled up, the peak 1 on the upper surface is obtained.
Since 03 coincides with the valley 104 on the lower surface, it gradually shifts as shown in FIG. 14 or alternately shifts as shown in FIG. 15, resulting in lack of stability.

The present invention has been made to solve the above-mentioned conventional technical problems, and it is an object of the present invention to provide a floor level adjusting plate which can be stably laminated with a simple structure and a method of installing the same. is there.

The floor level adjusting plate according to the first aspect of the present invention is provided between a device and a floor on which the device is installed. A plurality of protrusions are formed on the upper surface, the protrusions on the upper surface correspond to the recesses on the lower surface, and the recesses on the upper surface correspond to the protrusions on the lower surface.

According to a second aspect of the present invention, a floor level adjusting plate is provided between a device and a floor on which the device is installed. Correspond to the wave troughs on the lower surface.

According to the present invention, the projections or ridges on the upper surface of the floor level adjustment plate which is lower when stacked are aligned with the recesses or valleys on the lower surface of the floor level adjustment plate which is upper. It is possible to prevent the floor level adjustment plate from shifting during use. In particular, since the protrusions or ridges on the upper surface of the floor level adjustment plate correspond to the recesses or valleys on the lower surface, no deviation occurs between the upper and lower floor level adjustment plates in the stacked state, and stable equipment can be provided. Horizontal installation can be realized.

According to a third aspect of the present invention, the recesses are formed in a lattice on the upper surface and the lower surface.

According to the third aspect of the present invention, in addition to the above, concave portions are formed on the upper surface and the lower surface in a lattice shape, so that the amount of material used for the floor level adjusting plate is reduced and the production cost is reduced. be able to. In particular, since the recessed portion is formed in a lattice shape, there is no problem in strength.

According to a fourth aspect of the present invention, in the second aspect, the floor level adjusting plates are brought into contact with each other so that the extending directions of the peaks and the valleys are alternately orthogonal to each other. It is.

According to the fourth aspect of the present invention, the floor level adjusting plates of the second aspect are brought into contact with each other so that the extending directions of the peaks and the valleys are alternately orthogonal to each other. Since they are juxtaposed, even if the laminated floor level adjusting plates are displaced in the extending direction of the peaks and the valleys, they can be prevented by the floor level adjusting plates juxtaposed therewith, and the stability is improved. It will further improve.

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 is a perspective view of the prefabricated refrigerator 1 described above, FIG. 2 is an enlarged sectional view of a skid 2 portion of the prefabricated refrigerator 1, and FIG. 3 is a perspective view of a floor level adjusting plate 11 of the present invention. As described above, one floor level adjusting plate 11 is provided between the skid 2 of the prefabricated refrigerator 1 and the floor surface FL, or
Two or more sheets are laminated and interposed at a predetermined interval (about 50 cm),
It is used to take the horizontal level (again, this is also indicated by P in FIG. 2).

In this case, the floor level adjusting plate 11 of the present invention is formed of a hard synthetic resin such as polypropylene (PP), and has a rectangular thin plate shape having a width of 40 mm and a length of 80 mm. The upper surface and the lower surface of the floor level adjusting plate 11 are formed in a corrugated shape, and ridges (convex portions) 12 and valleys (recesses) 13 extending in the longitudinal direction are formed alternately.

The waveforms of the upper surface and the lower surface have the same shape, and the height D of the peak 12 (the depth of the valley 13) is 0.2.
~ 0.5mm (preferably 0.25mm), pitch is T
Is 1 mm to 2 mm (preferably 1 mm), and the open angle θ of the valley 13 is about 110 degrees (that is, the inclination angle of the peak 12 is 30 to 40 degrees, preferably about 35 degrees).

In particular, the ridges 12 on the upper surface correspond to the valleys 13 on the lower surface, and the valleys 13 on the upper surface correspond to the ridges 12 on the lower surface. Further, concave portions 14 are formed in a lattice shape on the upper surface and the lower surface of the floor level adjusting plate 11 so that the floor is adjusted. The depth d of the recess 14 is about 1.5 mm,
The distance t between the recess 4 and the recess 14 is set to about 2 mm, and the side surface of the recess 14 is inclined in a direction approaching at the bottom. Thereby, the strength is improved. If the thickness of the floor level adjusting plate 11 is small, the recess 14 may not be formed.

When a plurality of such floor level adjusting plates 11 are stacked, as shown in FIG. 7, the crest 12 on the upper surface of the floor level adjusting plate 11 on the lower side becomes the lower surface of the floor level adjusting plate 11 on the upper side. Valley 13 Here, if the waveform is too shallow or the pitch is too large, the engagement between the peaks and the valleys becomes thin, which is not useful for preventing displacement, but in the embodiment, the dimensions of the waveform are set as described above. Because there is a mountain 12
When the floor level adjusting plate 11 is used during use,
Are effectively prevented from shifting. still,
A mark (not shown) is formed on the lower surface of the floor level adjusting plate 11 so that the user can easily use the mark on the floor level adjusting plate 1.

In particular, the peaks 1 on the upper surface of the floor level adjusting plate 11
2 corresponds to the valleys 13 on the lower surface, so that the upper and lower floor level adjusting plates 11 and 1 in the stacked state as shown in FIG.
1 are stacked vertically without any deviation, and stable horizontal installation of the equipment can be realized.

Since the recesses 14 are formed in a lattice pattern on the upper and lower surfaces of the floor level adjusting plate 11, the amount of resin material used for the floor level adjusting plate 11 is reduced, and production costs are reduced. be able to. And since the recessed part 14 is formed in the shape of a lattice, there is no problem in strength. In particular, since both sides are formed in a lattice shape, the occurrence of warpage or bending during resin molding can be minimized. In addition, since the contact surfaces are formed in a lattice shape, the load per unit area when stacked is increased, and the effect of preventing displacement is improved.

Next, when the floor level adjusting plate 11 is actually installed below the skid 2, the floor level adjusting plate 11 is abutted so that the longitudinal directions thereof are alternately orthogonal to each other.
(A predetermined number of each are stacked). Thereby, the extending directions of the peaks 12 and the valleys 13 of the floor level adjusting plate 11 are alternately orthogonal to each other, so that the stacked floor level adjusting plates 11 extend in the extending directions of the peaks 12 and the valleys 13. In the case of deviation, the floor level adjustment plate 11 juxtaposed in contact with the deviation can be prevented,
Stability is further improved.

In the embodiment, the shapes of the upper surface and the lower surface of the floor level adjusting plate 11 are corrugated. However, the present invention is not limited to this, and irregularities of the same shape may be formed alternately. Also in this case, the convex portion on the upper surface corresponds to the concave portion on the lower surface, and the concave portion on the upper surface corresponds to the convex portion on the lower surface.

In the embodiment, the present invention is applied to a prefabricated refrigerator. However, the present invention is not limited to this, and the present invention is effectively applied to any equipment that needs to be leveled by inserting a floor level adjustment plate between the refrigerator and an installation floor. It is.

[0025]

As described above in detail, according to the present invention, the projections or hills on the upper surface of the floor level adjusting plate which are lower when stacked are formed by the concave portions on the lower surface of the floor level adjusting plate which is upper. Since it matches the valley, it is possible to prevent the floor level adjustment plate from shifting during use. In particular,
Since the protrusions or ridges on the upper surface of the floor level adjustment plate correspond to the recesses or valleys on the lower surface, the upper and lower floor level adjustment plates are stacked vertically without any deviation in the stacked state, and are stable. This enables the horizontal installation of the equipment to be realized.

According to the third aspect of the present invention, in addition to the above, concave portions are formed on the upper surface and the lower surface in a lattice shape, so that the amount of material used for the floor level adjusting plate is reduced, and production costs are reduced. be able to. In particular, since the recessed portion is formed in a lattice shape, there is no problem in strength. In addition, since the contact surfaces are formed in a lattice shape, the load per unit area when stacked is increased, and the effect of preventing displacement is improved.

According to the fourth aspect of the present invention, the floor level adjusting plates are brought into contact with each other so that the extending directions of the peaks and the valleys of the floor level adjusting plates of the second aspect are alternately orthogonal. Since they are juxtaposed, even if the laminated floor level adjusting plates are displaced in the extending direction of the peaks and the valleys, they can be prevented by the floor level adjusting plates juxtaposed therewith, and the stability is improved. It will further improve.
