Is a condensation phenomenon that occurs in the atmosphere.
Generally, when the temperature difference between the air in the air and the surface of the wall of the building in which the air is in contact is more than 30%, the saturated water vapor contained in the air liquefies at the moment of contact with the wall surface. have.

One. Surface condensation prevention Construction method
Condensation on the surface of a wall refers to the phenomenon where the moisture on the surface of the wall is liquefied when the temperature of the surface of the wall falls below the dew point of the moisture in the room.
The method of constructing such surface condensation is as follows.
(1) removing condensation generated on the wall surface (s100)
First, remove condensation on the surface of the wall using a towel or hot air. Also, at the same time, the surface of the wall should be cleaned and prepared so that it can be easily adhered when applying a crack repair agent or an anti-condensation agent.
(2) a step of removing metal reinforcing members (foam tie) and reinforcing bars formed on the wall (s200)
In this step, metal mold joints protruding from the surface of the wall, so-called foam ties, are removed. And removing the reinforcing bars projecting from the inside of the wall to the outside surface.
Although such metal moldings and reinforcing bars have a very direct effect on the formation of condensation, they have been overlooked in the construction site. In the present invention, the metal structures are necessarily removed.
Since metal has a higher heat transfer rate than the wall, condensation occurs at each site due to cooling effect by cold air outside the wall through such reinforcing bars. The surface temperature of the room wall surface is directly lowered.
(3) step (s300) of rubbing the metal mold joint material and the end portions of the reinforcing bar removed in step s200 and applying the coating agent,
the end portions of the metal reinforcing bars and the metal molding joints protruding from step S200 are removed so as not to rust, and then the coating agent is applied to the end portions of the metal reinforcement.
(4) heating the wall and applying a crack-repairing agent to cracks in the wall (steps s350 and s400)
In this step, a moisture-proof material is applied and infiltrated in order to prevent the moisture contained in the wall from permeating, thereby forming a coating film (s350).
Then, if necessary, the wall is heated by the soil, and the crack repairing agent is applied. When the wall is heated, the moisture of the wall is removed and the crack repairing agent is more likely to stick to the surface of the wall. As a crack repair agent, a known substance as a crack repair agent containing a substance such as calcium carbonate as a main component should be used.
(5) a step (S500) of operating the dehumidifier for 12 hours to 36 hours to remove the moisture inside the building or the underground parking space,
In this step, moisture present in the space (underground parking lot, building interior) confined by the wall is extracted to the outside of the space. If the moisture continues to come in contact with the surface of the wall continuously during the dew condensation preventing operation, the crack repairing agent or the dew condensation preventing coating material to be subsequently applied does not adhere to the surface of the wall, and the efficiency of the dew condensation preventing construction drops sharply.
Moisture content is also contained in the coating material for crack repairing agent and dew condensation. If the humidity is high in the air, the moisture contained in the material itself does not evaporate, and the above-mentioned materials flow down due to gravity. 16 shows an example of such an erroneous construction that is caused by the problem that the moisture in the air is not sufficiently removed and the moisture contained in the coating material for preventing condensation is not evaporated smoothly. In the present invention, such problems have been captured and it has been proposed to improve the dew condensation preventing construction work as an essential constitutional step of the invention.
This process is a very important process for the dew condensation preventive construction method even if it is seen simply, and this process corresponds to the essential process of the present invention which is not shown in the prior art at all.
(6) A step of performing first coating of a coating material for preventing condensation (s600)
After performing step s500 to remove the moisture in the space enclosed by the wall, the wall must be heated again by the tundish. The coating material (or the dew condensation preventing agent) for preventing condensation is applied alternately in the horizontal and vertical directions do. The thickness to be applied is preferably about 0.5 to 1 mm, but is not limited thereto.
The coating material for preventing condensation should be formed of a material having a low heat conductivity because it is the main cause of heat transfer to the surface of the interior wall. When the water repellent agent is mixed together with these materials, the characteristics of the water repellent agent are expressed.
That is, since the wall surface is rapidly contaminated by the water absorption process, the moisture is absorbed and the liquid water can not penetrate into the wall or wet the surface.
(5 parts by weight), titanium dioxide (15 parts by weight), baked diatomite (20 parts by weight), christvillite (10 parts by weight), limestone (5 parts by weight), hydroxymethylcellulose Ether (5 parts by weight) is added to water (the remaining part by weight).
Usually, it is a known material except for loess as a heat insulating coating material. In the present invention, there is a specific feature that loess is added to improve the effect of insulating the inside wall, thereby helping to prevent condensation. It should be noted that the composition ratio of the coating material is not limited to the above-described values but can be changed and applied.
(7) activating the dehumidifier for 12 hours to 36 hours to remove moisture in the building or underground parking space (s700), and performing a second application of the coating material for preventing condensation while heating the wall of the condensation portion (s800)
In this step, the coating material for preventing condensation as in step s600 is further applied in the horizontal and vertical diagonal directions, and the dehumidifier is actuated to enhance the adhesion of the coating material for preventing condensation on the surface of the wall.
On the other hand, it may include a step of applying diatomite in place of the step s800. The diatomaceous earth is a porous material, and an air layer is formed in the inside of the diatomite. Therefore, there is an advantage that the moisture in the air can be prevented from being formed by dew condensation in the liquid state.
As described above, moisture is contained also in the coating material for crack repairing agent and dew condensation. If the humidity is high in the air, the moisture contained in the material itself does not evaporate, causing a problem that the materials flow downward due to gravity Therefore, it is important to continuously remove moisture from the air.
After the completion of step s800, the dehumidifier is operated for 12 hours to 36 hours to remove the moisture in the inside of the building or the underground parking space (s900) so that the coating material for preventing condensation (secondary coating) And then cured.
The most important point in preventing the condensation on the surface of the wall is i) the process of heating the wall surface and ii) the moisture inside the space surrounded by the wall is removed by the dehumidifier. There is a problem in that the adhesion property on the surface of the wall is extremely deteriorated such as the crack repairing agent and the coating film for preventing condensation flowing down on the wall surface, and thus the dew condensation preventing work must be performed again.
2. Construction method of condensation inside wall
The construction method for condensation inside the wall is as follows.
That is, step (s1) of removing condensation generated on the wall surface; A step (s2) of removing a metal form joint material (foam tie) and a reinforcing bar protruding from the wall; Step (s3) of rusting the metal mold joint material and the reinforcing bar end portions removed in step s2 and applying the coating agent is the same as in the case of the wall surface condensation prevention construction.
Then, a step (s4) of inserting the insulated injection material is performed by drilling the inside of the wall in an oblique direction on the wall surface.
As the heat insulating injection material, known materials having low thermal conductivity such as polyurethane foam, urea foam, heat insulating mortar and the like may be used.
Inserts a sufficient amount of filler material to allow backflow.
Then, a step (s5) of piercing the part of the piercing joint where the wall and the bottom face meet and injecting the heat insulating injecting agent is performed. Of course, the process sequence in steps s4 and s5 may be changed.
Next, the step (s6) of applying a crack repair agent to the cracked portion in the wall while heating the wall is performed is the same as the method of constructing the wall surface condensation.
Then, the dehumidifier is operated for 12 hours to 36 hours to remove the moisture in the inside of the building or the underground parking space (s7), thereby increasing the adhesion of the coating material for preventing condensation to be applied to the surface of the wall Is described in the above-mentioned wall surface condensation prevention construction.
Then, the wall is heated again to perform the first coating step (s8) of dew condensation coating material, and the dehumidifier is continuously operated for more than 12 hours and 36 hours to remove the moisture in the building or underground parking lot. s9)
As a further work, a step (s10) of performing secondary coating of a coating material for preventing condensation while heating the wall of the part where condensation has been observed is performed, and the dehumidifier is continuously operated for at least 12 hours to 36 hours, Let the moisture in the parking space be removed. (S11)
I) the step of heating the surface of the wall in the process of the present invention and ii) the dew condensation is performed while the moisture inside the space surrounded by the wall is removed by the dehumidifier, so that the tackiness on the surface of the wall of the crack- So that there is an advantage that effective condensation prevention construction is achieved.
