Description

DETAILED DESCRIPTION OF THE INVENTION Today, floor polishing is carried out by attaching abrasive paper, which is entirely disk-shaped, to a vat stand with a bell and cross of a floor polishing rock. By the way, in the conventional methods, the durability of polishing is generally short, that is, in the case of terrazzo polishing, clogging occurs in about 3 to 4 minutes and the entire surface becomes slippery, making polishing impossible and reducing the grinding performance. Decrease dramatically. In order to prevent this, it may be possible to apply a load to the upper part of the polishing plate, but this has the disadvantage that it becomes difficult to operate.

The present invention has been developed to solve the above-mentioned problems, and an example of the application of the present invention will be described below with reference to the drawings.

FIG. 1 shows an abrasive paper 1 used in the present invention, in which A is a plan view, B is a back view, and C is a cross-sectional view of A along the line X=X.

In this example, the abrasive paper 1 is formed into a bell shape 9, and the surface a
A large number of grindstone powders P are integrally layered with a thermosetting resin. On the other hand, a tricot cloth Q is attached to the back side so that it can be detachably attached to the Velcro fastener on the pad table on the polishing machine side. It is a top view of the h+ putt table 2 in a state where it is fixed. This figure shows an example in which 6 sheets of Uta paper l are fixed, but the padding table 2 is used for fixing them.
A plurality of abrasive papers are placed on the surface of the pad in a radial direction from the center of the padding table, that is, adjacent abrasive papers 1's lbt 1

. . . It is fixed in such a way that it is formed.

In the present invention, the rate at which a plurality of abrasive papers L are fixed to the pad table 2 as described above is determined by the sum of the gaps S1, S2, SS, etc. relative to the total area S of the pad table 2. 20%~8
0%, preferably in the range of 30 to 70%, and each abrasive paper 1
are fixed in a state where they are approximately evenly arranged in a radial direction from the center 0 of the pad table 2.

In the above embodiment, the conventional pad table 2 is used as it is, and the pad table 2 is fixed at an arbitrary position. - It is possible to create and use a special putting table that partially limits the position or partially removes the sponge on the white side of the bat. With this structure, the padding table can be made lighter, less expensive, and work performance can be improved.

FIG. 3 is a diagram showing the floor polishing surface in use, with reference numeral 3 indicating the main body of the floor polishing surface, 4 a drive motor, 5 a handle, 6 a sponge body, and 7 a Velcro fastener.

The present invention is carried out as described above, and instead of covering the entire surface of the pad table with ω-karakami, in other words, a plurality of abrasive papers are placed next to each other in a radial direction from the center of the pad table. They are fixed so that a certain percentage of gaps are formed in the relationship, and this allows for even surface contact even with uneven floors, unlike conventional The problem of insufficient grinding load does not occur, and the polishing pressure per unit area can be increased with light operation. In addition, since the grinding debris is discharged to the outside through the gaps between the abrasive papers, clogging is naturally prevented.According to the inventor's experiments, the durability of the abrasive paper has been improved from 3 to 30% compared to the conventional one.
By increasing the time from 4 minutes to over 10 minutes, the service life can be increased by more than three times.

In the above embodiments, the abrasive paper was described as having a bell-like shape, but it can be formed into any other shape such as a rectangular shape, a bow shape, and the abrasive paper may be an abrasive cloth. There is no problem and these are included within the scope of implementation of the present invention.

In the practice of the present invention, when the gap between each abrasive paper attached to the pad table is 20% or less, especially 10% or less of the surface area of the pad table, it will not be substantially different from that of a case where the entire surface is fixed, and 80% or less of the surface area of the pad table. % or more, particularly 90% or more, it is not preferable because the ω1 calendar effect will actually decrease. In the present invention, the preferable range for particularly excellent work performance is 30% to 70%. In addition, compared to abrasive paper in which holes of a certain size are simply made on the surface, the one of the present invention is superior in that it allows the abrasive debris to be naturally discharged to the outside without being retained inside. Moreover, since the abrasive paper can be partially detached and replaced, the abrasive paper can be used effectively to the end.
