Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a coating layer mainly composed of diatomaceous earth that is coated on the lower surface of a folded plate envelope to prevent noise and bind. The present invention relates to a diatomaceous earth-coated repair folded plate outer envelope with good properties.

[Conventional technology and its problems]

Conventionally, there are many houses that use folded metal plates as roofing materials. In this case, dew condensation occurs on the lower surface of the roofing material, which has the disadvantage of staining the interior of the house and having an adverse effect on furniture and furnishings. Furthermore, inside the system, during rainy season, the sound of rain becomes louder, causing noise.

Furthermore, although it has recently been discovered that diatom earth has excellent heat insulation and watertightness, there has never been a metal folding material coated with diatomaceous earth directly. When simply painted, the folded metal plate has a large coefficient of thermal expansion, so it expands due to the influence of outside air.
The shrinkage is repeated, which causes cranks to appear on the diatoms that have been applied at a relatively early stage. It had the disadvantage of separating l+.

(Means for Solving the Problems) Therefore, as a result of intensive research in order to solve the above problems, the inventor has proposed the invention to the lower surface of a folded plate outer enclosure in which valleys and peaks are continuous. By applying a coating layer of baked diatomaceous earth powder mixed with a binder and kneaded with water to a predetermined thickness, it has good adhesion, excellent heat insulation, noise prevention, and dew condensation prevention, and has solved the above problems. It is resolved.

The peak portion 2 of the folded plate outer plate A2, which is this unit component, forms a mountain shape when folded and continuous, and forms half the shape of the peak portion 2 of the folded plate outer plate A1,
The opposing lower part 6a and upper part 6b of the adjacent folding plates Ax and At are joined together with the end of the hanger 5 on the receiving metal fitting 4 (see the drawing). The shape is not limited to that of the embodiment as long as the upper ridge part 6b is joined to the lower ridge part 6a.

In addition, the fitting folded plate outer plate A and the cap material A of the third embodiment are

The fitting folded plate outer enclosure +Ii A 31 in the folded plate outer enclosure A (see Fig. 5) composed of is formed with bent fitting parts at the upper ends of both sides of the valley l, and the fitted part parts are bent. and cap material A after mating. A mountain portion 2 is formed by this. Its fitting folded plate outer plate A.

is fixed with a hanger 5 attached to a receiving metal fitting 4 on the structural member 3. Although not shown, if the folded plate outer enclosure A has the condition that the troughs 1 and the peaks 2 are continuous, even if other elements are added, the folded plate outer enclosure It is included in the scope of A.

Moreover, as shown in FIG. 6, the folded plate outer envelope A for fitting may be configured in the form of a stacked folded plate so that one side fits on the other side.

The unit outer plate constituting the folded plate outer cover A may be made only of metal such as a galvanized iron plate, or, as shown in FIG. It may also be a polyvinyl chloride laminate formed by wrapping it in vinyl. Generally, the material is mainly a metal plate, but the material is not necessarily limited as long as it is long and can be plastically worked into a corrugated cross section using multistage rolls or the like.

7 is covered by 1'1llll! The diatomaceous earth is about 1000°
After firing at a temperature around C, it is made into a powder, and a polymer material such as an acetic acid resin such as polyvinyl acetate or an acrylic resin such as a polyacrylic ester as a main component is applied on the powdered fired diatom. A relatively large amount of binder is mixed, and about 40% water is added to the binder-containing powdered calcined diatomaceous earth, which is then kneaded and dried. Since the binder has excellent adhesive performance, it plays the role of not only bonding the powders together, but also bonding the coating layer 7 and the folded plate envelope A.

The coating layer 7 composed in this manner is applied to the lower surface (back surface) of the folded plate envelope A. In actual manufacturing, the folded plate enclosure A is inserted into the lower surface (back surface) of the existing roof or existing wall of an existing factory, warehouse, company, etc., and an appropriate amount is poured onto the powdered calcined diatom containing the binder. Water is added and kneaded into a fluid state, which is then sprayed with a spray gun 8 or spread with a roller as shown in Fig. 4, or further used for plastering work with a trowel. Then, the coating layer 7 is applied to substantially the entire lower surface (back surface) of the folded plate envelope.

Diatomaceous earth is soil formed by the accumulation of remains of phytoplankton, and because its origin is plants, it is an extremely fine inorganic material with excellent breathability and a porous composite particle composition. .

Since it is derived from phytoplankton, it has approximately 50 to 100 pores (air N) in its 100 to 200 particles, and has breathability that is incomparable to other materials. It is soil. For this reason, it has traditionally been used in fireproof bricks and also in household and commercial stoves.

Here, breathability refers to an increase in the amount of water vapor in the room,
When the amount of water vapor decreases, materials facing the interior of the room absorb or release water vapor accordingly. This breathability depends on the relative humidity in the room.
When the indoor relative humidity increases, moisture is absorbed, and when the relative humidity decreases, moisture is released. This phenomenon repeats. Moreover, the breathable material is called a humidity control material.

The concept of respirability is different from the concept of permeability, which means that when the amount of water vapor inside and outside a building differs, a pressure difference occurs and it flows from the higher pressure side to the lower pressure side. say.

In this case, depending on the properties of the constituent materials, some allow a large amount of water vapor to pass through, others allow less water vapor to pass through, or some allow no water vapor to pass through at all. Such permeable humidity control materials have the ability to prevent dew condensation experimentally. This is to keep the water moist and prevent condensation from appearing on the surface.
When the moisture content gradually increases and the surface reaches an equilibrium moisture state, water droplets (knots) can be seen. For this reason, the necessary and sufficient conditions for preventing dew condensation are particularly excellent i3 moisture (permeability) and breathability.
Such conditions are provided for the coating layer 7 whose main component is diatomaceous earth which is porous and has a composite particle composition.

If the insulation performance is not good, the temperature at the surface of the material will be low, the difference between the actual water vapor pressure and the saturated water vapor pressure will widen, and the amount of condensed water will increase, so a material with a large moisture capacity will be required. . Therefore, for a material that does not generate dew condensation, it is important to have excellent breathability, excellent moisture permeability (permeability), and heat insulation performance, as well as a large moisture capacity.

Among these, particularly important conditions include excellent breathability and large moisture capacity (large amount of water absorption compared to its own weight).

The experimental measurement results for such a coating layer 7 include the thermal conductivity λ.・. = 0.15 cal/ah 'C and has excellent heat insulation properties. By the way, mortar 1.30 Kcal/w
h 'C1 wall soil 0.77 Kcal/mh 'C. In addition, it has a maximum moisture capacity of 90%, has excellent moisture permeability, and has excellent water retention (bulk specific gravity 1.00 to 1. l 2 ).
. Furthermore, in the impact test, there was no cracking, significant deformation, or peeling from the substrate. In the aging test, there was no discoloration even after 250 hours of irradiation with an ultraviolet long-life weather meter, and in the Condensation 2i test, no dew condensation occurred.

No ignition occurred in the ignition test. In this way, the mineral composition (
Composite particle composition) and has excellent nonflammability and fire resistance. moreover,
It is obvious that diatoms originate from phytoplankton and microparticles, and because they are porous, they have excellent respiration.

Next, the diatomaceous earth-covered repaired folded plate outer enclosure, that is, the repaired folded plate outer enclosure with the coating layer 7 was used as a roof structure, and an experiment was conducted regarding rain noise directly below the outer enclosure. Specifically, on the top (surface) of a polyvinyl chloride laminate (non-unit g!A version) with a thickness of 0.6 m,
A roof board coated with a coating layer 7 of approximately 3fflII1w-;
Rain noise (1) D noise) was simply measured directly below a polyvinyl chloride laminate (unit outer panel) with a thickness of 0.6 m.

With the amount of rainfall set to a predetermined value, to the folded plate outer enclosure with the covering layer 7,
The background noise was 51.8 dB (decihels), and the background noise of only the unit outer plate was 70.1 dB, which was a value that numerically reduced the health by more than 35%.

〔Effect of the invention〕

In the present invention, on the lower surface of the folded plate envelope in which the valleys 1 and the peaks 2 are continuous, a coating layer 7 made by mixing a binder with diatom powder found at the bottom of a mine, adding water, and kneading is applied to a predetermined thickness. By using a folded plate outer envelope for repairing the diatom coating, first, it can prevent condensation, second, it can prevent noise, third, it has excellent insulation performance, and fourth, it is easy to install. It is effective in that it can be done quickly.

To explain these effects in detail, first, by using the repair folded plate outer envelope with the coating layer 7, dew condensation on the indoor side can be prevented. In other words, as mentioned above, diatoms have excellent respiration properties,
In addition, since the heated air capacity is large, it is extremely difficult for condensation to form on the outside of diatomaceous earth even if the temperature difference between inside and outside becomes large, and it has the advantage of being able to almost avoid condensation that conventionally occurs in ordinary houses.

Moreover, if the repaired folded plate outer enclosure with the covering layer 7 is used as a roof,
Rain noise (background noise) inside the room is reduced, making it a good noise countermeasure. Furthermore, it is suitable for various noise countermeasures even when it is not raining.

In addition, diatom earth has traditionally been used for firebricks and for household and commercial stoves.In addition to being non-combustible and having good fire resistance, diatomaceous earth of a certain thickness has excellent heat insulation properties. The main component of the coating layer 7 is diatomaceous earth, which is inexpensive. Therefore, the diatomaceous earth-coated repair folded plate enclosure can be provided at a relatively low cost.

In addition, on diatoms, the occurrence of cranks due to expansion and contraction due to temperature changes is extremely rare, and furthermore, a coating layer 7 mainly composed of diatomaceous earth is applied to the lower surface (back surface) of the existing folded plate envelope A. However, due to the presence of the binder contained in the coating layer 7, it is difficult to separate the coating layer 7 from the folded plate envelope.
It can be suitably used as a construction board for a long period of time.

Furthermore, in the present invention, a coating layer 7 made by mixing a binder with fired diatomaceous earth powder and kneading it with water is applied to the back surface of the folded plate envelope A, and the manufacturing process I,
In this case, the coating layer 7 is not coated with an adhesive, but is merely coated with a fluid or liquid substance by spraying, etc., and is applied to the lower surface of a factory, etc. (inner side in the case of a wall). Since it is sprayed from above, scaffolding is required, but it has the effect of making on-site construction relatively simple and quick.
