Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a horizontal coating device for a floor surface on which a precision machine such as a floating neutron scattering device is installed.

(Prior art) For example, when installing a floating neutron scattering device, etc., it is required to have motion performance that allows it to operate horizontally with a small floating distance of 20 to 25 μm from the floor. A smooth floor surface is required. For this reason, precision-polished stone such as marble or stainless steel has traditionally been used as floor surfaces, but these are difficult to repair when scratches occur, and stone or stainless steel materials are difficult to repair. The area per sheet was limited, making it impossible to obtain a seamless, large-area floor, and the price was high.

Therefore, recently, floors using synthetic resin have been considered. The synthetic resin has fluidity during painting and hardens after painting.Generally, a mixture of liquid epoxy resin and a curing agent containing active hydrogen, or in some cases pigments, is proposed. The department has already put it into practical use.

(Problem to be Solved by the Invention) However, in order to obtain a highly accurate horizontal and smooth floor surface, floors using this synthetic resin cannot be painted using the usual painting methods such as troweling, brushing, roller painting, or spraying. Painting was technically extremely difficult.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a horizontal coating device and a method for coating this floor surface, which can obtain a resin floor with highly accurate horizontality and flatness.

(Means for Solving the Problems) The present invention is characterized in that rails are installed at regular intervals, level adjustment means is provided on the bottom surface of the rails, and the spreading scraper slides along the rails. However, it is located in the area where the paint shrine is spread at the spreading part of the whole area scraper.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

The present invention consists of rails 1 and 2 and a spreading screen 3.

The rails 1.2 are installed at predetermined intervals on the floor F to be painted, and these rails are linear with flat upper surfaces 1a and 2a. Adjustment screws 4, which are level adjustment means, are installed at 2m intervals.
... 5. Two screws are screwed into the bottom plate of this rail, two at each location. And on the top of rail 1.2,
In order to rotate the adjusting screws 4...5..., through holes 1b and 2b are drilled into which the lower end of the screw driver can be inserted. It can be expanded and contracted up and down by turning.

The spreading scraper 3 has a main body 31 provided with a spreading member 32 which is a spreading part, and this spreading member is provided below the main body 31 via adjustment screws 6, 6a. It is something. The lower surfaces 31a at both ends of the main body 3 of the spreading souffler 3 are also formed into flat surfaces that contact the upper surfaces 1a and 2a of the rails 1.2. And the main body 31 has rails 1.2
The spreading member 32 spreads the coating material. Although the spreading member 32 is illustrated as a flat plate whose lower surface is straight, it goes without saying that this spreading member is not limited to the plate shape but may be cylindrical or rod-shaped.

The rail 1.2 and the scraper 3 are preferably box-shaped from aluminum, stainless steel, or iron plates from the viewpoint of shape stability and weight reduction.

Further, elastic plates 7 are attached to the lower surfaces of both ends of the spreading member 32 in alignment with the straight line of the lower surfaces. Elastic plate 5
is located directly below the rail when the scraper 3 is placed on the rail 1°2. The material of the elastic plate 7 can be a single material selected from steel, synthetic resin, base rubber, reinforced plastic, etc., or a composite material of at least two kinds. Appropriate dimensions thereof are length 20-80 mm, width 2-10 mm, and thickness 0.1-2 mm.

The elastic plate 7 bends when it comes into contact with the adjustment screws 4 and 5 for adjusting the level on the lower surface of the rail 1.2 when the scraper 3 is moved, and returns to its original state when it passes through, thereby spreading the paint to a constant width.

Next, the coating method will be explained.

First, one rail 1 is installed on the floor F to be painted.

Then, adjust the height by turning the adjusting screw 4 left and right so that the upper surface 1a of the rail 1 is level. Next, another rail 2 is made parallel to the previously installed rail 1 and installed in the same manner. In that case, the spacing between the rails 12 is set to such an extent that the spreading scraper 3 does not fall off the rails.

After installing the rails 1 and 2, place the soufflé par 3 on this rail, and adjust the gap between the bottom surface of this screen and the floor F using screws 4.5 (size: diameter 3 mm x length 3).
~5 cm) at the highest part of the base layer according to the target film thickness.

In this case, adjustment is made by turning the adjustment screw 6.6a so that the lower surface of the spreading member 32 of the scraper 3 is kept horizontal.

As described above, after installing the rails 1-12 and adjusting the horizontality and height of the spreading member 32 of the scraper 3, paint is poured between the rails and the main body 31 of the scraper
When the paint is moved along the rail, the bottom edge of the spreading part set 32 spreads the paint.

In that case, the paint is poured continuously so that no gap is created between the paint and the lower surface of the spreading member 32 of the scraper 3.

After spreading the paint as described above, remove rail 1.2 and scraper 3 before the paint hardens.

This apparatus can also have a structure in which a plurality of units are combined vertically and horizontally depending on the size of the floor area to be coated.

The size of this device can be changed as necessary depending on the area coated with the paint, but preferably, the size of the rail 1,
2 has a length of 400. cm x width 5 cm x height 5 cm + T
l x wall thickness 0.15cm, distance between rails 1.2 is 200c
m, the length of the bottom end of the scraper is approximately 200 mm including the elastic plate.
A size of about cm is appropriate.

Next, an experimental example of a coating method using the apparatus of the present invention will be explained.

Experimental Example] In Experimental Example 1, as shown in the lower left corner of FIG.
Two rails 1 and 2 are connected and one scraper is installed on top of this rail.

A section measuring 8 m x 8 m was used. After finishing the mortar, it was allowed to dry for two months and then painted using the apparatus of the present invention according to the steps in Table 1.

Experimental example 2 This experimental example was conducted on the floor of the second newly constructed painting room in the Shiga factory of Chugoku Toyo Co., Ltd.
A section measuring 10 m long and 16.5 m wide within 16.5 m wide was used.

After finishing the mortar and drying it for two months, according to the process shown in Table 1, the rails 1 and 2 in the device of the present invention were made into 4 horizontal straight rows, 6 rows at 2 m vertical intervals, a total of 24 rails, and the scraper 3. I used 5 of them between the rails and painted them.

Experimental Example 3 In order to clarify the comparison between the effect of the present invention and the effect of the conventional example, this experimental example was applied to the remaining part of the floor shown in Experimental Example 1. (
(see Figure 3) was coated according to the steps in Table 1.

Experimental Example 4 This was also painted using the conventional troweling method as in Experimental Example 3, and the rest of the floor shown in Experimental Example 2 (
(see FIG. 3) was carried out according to the steps shown in Table 1.

Therefore, Table 2 shows the finish accuracy measurement results of Experimental Examples 1 to 4 and the base module that supports the neutron analyzer main body and floats gently from the floor using compressed air to facilitate the horizontal movement of the main body. (manufactured by Kuroda Seiko Co., Ltd., with 16 air roses) Mobility test results are shown.

High precision horizontal,
Moreover, it became possible to form a smooth synthetic resin floor.
