DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for sequentially protecting a surface of a structure, and more particularly to a method for protecting a surface of each part of a structure which is sequentially finished part by part from the adhesion of dirt until the entire structure is finished. About.

[0002]

2. Description of the Related Art In the construction of structures, concrete,
There is a case where an outer wall surface or an interior surface which is finished with a tile, a stone material, or the like is sequentially finished from a finishable portion. In this way, the finished surface to be sequentially finished (hereinafter, sometimes referred to as a sequentially finished surface) may have a finished surface of any part (hereinafter, referred to as a finished area) from the finish of the part to be finished first to the completion of the structure. ) Has a problem that the appearance at the time of completion is impaired due to the adhesion of the contaminants. In order to solve this problem, a method of cleaning a finishing area to which a dirt substance adheres immediately before completion has been performed. In addition, in order to protect each finishing area from the adhesion of a dirt substance, the finishing area of the part is covered with, for example, a vinyl sheet at the time of finishing each part, and the peripheral edge of the sheet and the peripheral edge of the finishing area are brought into close contact with each other to thereby remove the dirt substance. A method has been implemented to prevent intrusions until the completion of construction.

[0003]

However, the conventional method of cleaning a finishing area to which dirt is adhered, requires a lot of time and cleaning work, for example, when the dirt is difficult to remove or adheres to a high place. There are issues that require effort. On the other hand, according to the method of covering the finishing area with the sheet, the cleaning operation can be omitted, but there is a problem that it takes time and effort to cover each finishing area with the sheet so that the dirt substance does not enter.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for sequentially and reliably protecting a finished surface from dirt by a simple operation.

[0005]

With reference to the embodiment of FIG. 1, a method for protecting a surface of a structure according to the present invention is provided. Solution 5 in which film-forming polymer 2 is dissolved in solvent 4
Is applied as a thin film 6 on the finishing surfaces 1a, 1b, 1c of the portion,
By evaporating the solvent 4, the thin film 6 is detachably adhered to the finishing surfaces 1 a, 1 b, and 1 c of the portion as the adhered film 7, and the solution 5 is formed.
Adhesion film 7 applied as a thin film 6 on the finishing surfaces 1a, 1b, 1c
Can be peeled off in a seal after evaporation of the solvent
Finishing all parts more after finishing the entire structure
The adhesive film 7 is peeled off from the surfaces 1a, 1b, 1c in a seal shape .

[0006] The peelable adhesion film forming polymer 2 has the property of being dissolved in the solvent 4, capable of being applied as a thin film on the surface 1, and forming a peelable adhesion film 7 by evaporation of the solvent 4. For example, polyvinyl alcohol can be used. For example, the type and combination of the polymer used as the adhesion film forming polymer 2 can be selected according to the material of the surface 1 to be protected, the period of protection, the environmental conditions around the surface 1, and the like. In addition, the adhesive film forming polymer 2
When polyvinyl alcohol is used, the solvent 4 can be water.

[0007]

The embodiment of FIG. 1 shows a sequential finishing surface 1 for sequentially finishing three finishing areas 1a, 1b, 1c. However, the sequential finishing surface 1 to which the present invention can be applied has a finishing area 1a, 1b, 1c which is adjacent to each other in FIG.
However, the finish areas 1a, 1b, and 1c can be used as the finish surfaces of distant portions of the structure. Hereinafter, the operation of the present invention will be described with reference to the flowcharts of FIGS. Finished area 1 this time in step 202 of FIG.
It is determined that the finishing of a is completed, and when the finishing is completed, the process proceeds to step 203, and the solution 5 of the adhesion film forming polymer 2 is applied to the entire finishing area 1a this time by, for example, a brush. FIG. 1 (A) shows solution 5
This time, the finish area 1a in which is applied as a thin film 6 is shown.

The solution 5 is prepared by dissolving the polymer 2 for forming an adhesive film in the solvent 4. The concentration of the deposited film forming polymer 2 in the solution 5 can be adjusted according to the material of the finishing area 1a, the surrounding environmental conditions, and the like. However, if the concentration is too high, the application as the thin film 6 becomes difficult. The present inventor has experimentally found that the concentration of the polymer 2 in the solution 5 is preferably in a range from the minimum concentration at which the adhesive film 7 described below can be formed to 50% by weight. According to the experiment of the inventor, 1
Preferably, the solution 5 is applied at a rate of 500 ml to 1 liter per m ^{2, and} the thickness of the thin film 6 is preferably 0.5 to 1 mm. When the solvent 4 evaporates, the thin film 6 having a thickness of less than 0.5 mm is easily peeled off by the adhered film 7 described later, and the finish area 1a may be exposed due to spontaneous peeling of the adhered film 7. If the thin film 6 is thicker than 1 mm, it may take too much time to form the adhesion film 7.

The solvent 4 in the thin film 6 applied to the finishing area 1a this time
Evaporates gradually, and as shown in FIG. 1 (B) and step 204 in FIG. 2, an adhesion film 7 is formed, which is detachably adhered to the finish area 1a this time. The present inventors, for example, polyvinyl alcohol
A solution 5 is prepared by dissolving the adhesive film forming polymer 2 in the solvent 4 at the above-mentioned concentration, and the solution 5 is applied as a thin film 6 having a thickness of 0.5 to 1 mm. It was confirmed by an experiment that an adhered film 7 that adheres and can be peeled off relatively easily can be formed. This finishing area 1a is shielded from the outside air by this adhesion film 7, and is protected from the adhesion of the dirt substance, so that the state at the time of finishing is maintained.

Referring to FIG. 2, the finishing of the entire structure is determined in step 205, and if there is an unfinished area, it is moved to the next finishing area 1b (step 206), and the steps described above for the next finishing area 1b are performed. Repeat 201 to 204. FIG. 1 (B) and
(C) shows the next finishing area 1b and the successive finishing area 1c to which the solution 5 of the adhesion film forming polymer 2 is applied. By repeating this cycle, the finished surface 1 of the entire structure can be sequentially covered with the adhesion film 7. In addition, as shown in FIG.
It can be sequentially adhered to the finishing surface 1 for a necessary period. For example, at the time of completion, step 207 in FIG.
By peeling off the adhesion film 7 from all the finishing areas 1a, 1b, 1c as shown in FIG. 7, the finished surface 1 at the time of completion can be made to have the appearance as designed without any adhesion of dirt.

Thus, the object of the present invention, that is, the provision of a "method of sequentially and surely protecting the finished surface from contaminants by a simple operation" can be achieved.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The application of the solution 5 to the finishing area 1a shown in step 203 in FIGS. 1 and 2 can also be performed by spraying the solution 5 with a spray or the like. Therefore, even when the finishing area 1a is wide, the application of the solution 5 can be performed easily in a short time. The peeling of the adhered film 7 from the finished surface 1 shown in step 207 of FIG.
Can be carried out in such a manner that the seal is peeled off from one end.
If the adhesive film 7 is difficult to peel off, the adhesive film 7 can be peeled off from the finished surface 1 by, for example, attaching an adhesive sheet (not shown) to the adhesive film 7 and peeling it off.

[0013]

As described in detail above, the method for protecting a surface of a structure according to the present invention in which the polymer for forming a peelable adhesive film is dissolved in a solvent at the time of finishing each part of the structure to be sequentially finished part by part. The resulting solution is applied as a thin film on the finished surface of the portion, and the thin film is adhered to the finished surface of the portion in a removable manner by evaporation of the solvent, and the attached film is peeled off from all portions after the entire structure is finished. Therefore, the following remarkable effects are obtained.

(A) The finished surface can be successively and reliably protected from the adhesion of a dirt substance by a simple operation of merely applying the solution of the deposited film forming polymer. (B) The exterior and interior surfaces when the structure is completed can have a beautiful appearance as designed without the attachment of contaminants. (C) By selecting an inexpensive polymer for forming an adhesive film and a solvent, a reduction in the total cost of preventing wall surface contamination can be expected.
