Description

Description: TECHNICAL FIELD The present invention relates to a floor horizontal coating apparatus for installing a precision machine such as a floating neutron scattering apparatus.

(Prior art) For example, when a levitation neutron scattering device is installed, it is necessary to have a motion performance capable of operating in a horizontal direction with a small clearance on the order of 20 to 25 μm from the floor. A smooth and smooth floor surface is required. Therefore, stones such as marble, which have been precision-polished, or stainless materials have been used as the floor surface, but it is difficult to repair them when scratches occur. The area per sheet was limited, it was not possible to obtain a seamless large-area floor, and the price was expensive.

Therefore, recently, floors made of synthetic resin have been studied. The synthetic resin has fluidity during coating and is cured after coating. Generally, a liquid epoxy resin and a curing agent having active hydrogen, and in some cases, a mixture of these with a pigment is proposed. The department has already put it to practical use.

(Problems to be solved by the invention) However, in order to obtain a highly accurate horizontal and smooth floor surface, a floor using this synthetic resin is a normal coating method such as iron coating, brush coating, roller coating, or spraying. It was painted, but this was technically very difficult.

Therefore, an object of the present invention is to provide a horizontal coating device capable of obtaining a resin floor having high precision horizontal and flatness.

(Means for Solving the Problem) A feature of the present invention is that it comprises a rail and a spreading scraper, and the rail is installed at a constant interval, and a level adjusting means is provided on the lower surface thereof. The spreading scraper comprises a main body and a spreading member, and the spreading portion of the spreading scraper is provided below the main body via a level adjusting means. From both ends of the spreading member of the scraper for use, an elastic member whose lower surface is at the same level as the lower surface of the spreading member extends outward, and the main body of the drawing scraper is attached to the rail. Sliding along, the coating material is spread by the spreading portion, and the elastic member is in contact with the level adjusting means of the rail by the movement of the spreading scraper, so that the deformation can be restored. Where it is.

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

The present invention, as shown in the first illustration, comprises rails 1 and 2 and a spreading scraper 3.

The rails 1 and 2 are installed on the floor to be painted (Figs. 2 and 3) F at a predetermined interval, and the rails have flat upper surfaces 1a and 2a.
And a plurality of adjustment screws 4 ... 5 ... which are level adjusting means are screwed into the bottom plate of the rail at a plurality of locations on the lower surface, for example, at intervals of 2 m, two at a location. . Then, through holes 1b and 2b into which the lower ends of the screwdrivers can be inserted are formed on the upper surfaces of the rails 1 and 2 in order to rotate the adjusting screws 4 and 5, and the adjusting screws can be rotated through the through holes. This allows it to expand and contract in the vertical direction.

The spreading scraper 3 is composed of a main body 31 and a spreading member 32, and the spreading member is provided below the main body 31 through adjusting screws 6, 6a which are level adjusting means. is there. The lower surface 31a at both ends of the main body 31 of the spreading scraper 3 is
It is formed on a flat surface in contact with the upper surfaces 1a and 2a of the rails 1 and 2. The main body 31 slides on the rails 1 and 2 and spreads the coating material by the spreading member 32. Spreading member 32
In the illustrated example, the lower surface is a flat plate shape having a straight line, but the spreading member is not limited to a plate shape, and may be a cylindrical shape or a rod shape.

The rails 1, 2 and the scraper 3 are preferably made of aluminum, stainless steel, or an iron plate in a box shape from the viewpoint of shape stability and weight reduction.

Further, elastic plates 7 of the same level as the lower surface are attached to the lower surfaces of both ends of the spreading member 32 in alignment with the straight line of the lower surface so as to extend outward. When the scraper 3 is placed on the rails 1 and 2, the elastic plate 7 is located directly below the rails and therefore contacts the adjusting screws 4 and 5. As the material of the elastic plate 7, a single material selected from steel, synthetic resin, synthetic rubber, reinforced plastic, or the like, or at least two kinds of composite materials can be used. It is suitable that the length is about 20 to 80 mm, the width is about 2 to 10 mm, and the thickness is about 0.1 to 2 mm.

Next, a method of coating a coating material by the apparatus of the present invention will be described.

First, one rail 1 is installed on the floor F to be painted. Then, the height is adjusted by turning the adjusting screw 4 left and right so that the upper surface 1a of the rail 1 becomes horizontal. Next, another rail 2 is made parallel to the rail 1 previously installed, and the height is adjusted and installed by the same method. In that case, the spacing between the rails 1 and 2 should be such that the spreading scraper 3 does not fall off from this rail.

When the installation of rails 1 and 2 is completed, then scraper 3 is placed on this rail, and the gap between the bottom surface of this scraper and floor F is adjusted with screws 4,5 (size: diameter 3 mm x length 3-5 cm). Adjust in the highest part of the base according to the target and film thickness. In this case, the spreading member of the scraper 3
Adjust by turning the adjusting screws 6 and 6a so that the lower surface of 32 is kept horizontal.

As described above, after installing the rails 1 and 2 and adjusting the levelness and height of the spreading member 32 of the scraper 3, the paint is poured between the rails, and the main body 31 of the scraper is moved along the rails. When moved, the lower end of the spreading member 32 spreads the paint.

In that case, the paint is continuously poured so that no gap is created between the paint and the lower surface of the spreading member 32 of the scraper 3. When the scraper 3 moves, the elastic plates 7 and 7 are clamped when they come into contact with the adjusting screws 4 and 5 on the lower surfaces of the rails 1 and 2, and are restored when they pass to restore the paint at the same level as other painted surfaces. Spread around the adjustment screw horizontally to a constant width.

After spreading the paint as described above, the rails 1 and 2 and the scraper 3 are removed before the paint is cured.

This apparatus may have a structure in which a plurality of units are combined vertically and horizontally according to the size of the floor area to be coated.

The size of this device can be appropriately changed depending on the coating area of the paint, but it is preferable to use rails 1 and 2
Is 400 cm long × 5 cm wide × 5 cm high × 0.15 cm thick, rail
The distance between 1, 2 is 200 cm, and the length of the scraper lower end is about 200 cm including the elastic plate.

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

Experimental Example 1 In Experimental Example 1, as shown in the lower left corner of FIG.
Two rails 1 and 2 are connected, and one scraper 3 is installed on this rail.

This is a floor with mortar trowel finish after pouring concrete in the first new laboratory in the Shiga factory of China Paint Co., Ltd., which is the applicant company of the present invention.
I used the part. After finishing the mortar, let it dry for 2 months,
Painting was performed using the apparatus of the present invention according to the process of Table 1.

Experimental Example 2 In this experimental example, the floor of the second newly established coating room in the China Paint Co., Ltd. Shiga Factory (the location shown in the upper right part of Fig. 3) is 20m long x 1 horizontal
A portion of 6.5 m in length 10 m x width 16.5 m was used.

After finishing the mortar, it is dried for 2 months, and according to the process of Table 1, the rails 1 and 2 in the apparatus of the present invention are 4 in a straight line in a horizontal direction, 6 rows in a vertical interval of 2 m, and a total of 24 scrapers.
Was painted between 5 rails.

Experimental Example 3 In this Experimental Example, in order to clarify the comparison between the effect of the present invention and the effect of the conventional example, iron coating was applied as in the prior art, and the remaining portion of the floor shown in Experimental Example 1 was used. (See FIG. 3) was coated according to the process of Table 1.

Experimental Example 4 This was also applied by the conventional iron coating as in Experimental Example 3, and the rest of the floor shown in Experimental Example 2 (see FIG. 3) was subjected to the steps shown in Table 1. It is a thing.

Therefore, Table 2 shows the base module that supports the results of measurement of finish accuracy and the neutron analysis apparatus main body of Experimental Examples 1 to 4 and slightly floats from the floor by compressed air to facilitate the horizontal operation (movement) of the main body ( The moving test results of Kuroda Seiko Co., Ltd. with 6 air pads are shown.

(Effects of the Invention) As shown in Table 2, in the device of the present invention, since the rail and the spreading scraper are provided with level adjusting means respectively, a large-area floor on which a precision machine or the like is installed. By applying a synthetic resin paint to the surface, it is possible to form a highly accurate horizontal and smooth synthetic resin floor, which has been difficult by the conventional ordinary coating method. In particular, since the elastic members extend from both ends of the spreading member of the spreading scraper at the same level as the lower surface of the spreading member, the elastic members are deformed by contacting the level adjusting means of the rail located on the lower surface of the rail. In addition, while being restored, the periphery of this level adjusting device can be painted horizontally at the same level as other painted surfaces.
