Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an external insulation structure for a wall and a method for performing external insulation on a wall. This article relates to a construction method for carrying out the construction and a structure to be used during the construction.

(Prior art) Conventionally, this type of external insulation construction method involves joining an already formed insulation material to an existing wall made of concrete or the like by driving anchor bolts, and then applying mortar, etc. to the top of the insulation material. There is a method of painting and construction.

(Problem to be solved by the invention) However, in such a construction method, the insulation material is joined to the wall surface by driving anchor bolts, so the joining between the two is not perfect (therefore, the insulation material is attached to the wall surface). Another problem has arisen in that there is a risk of the film peeling off or falling off.

Particularly in the above-mentioned external insulation construction method, separation or falling off of the insulation material is fatal, and there has been a conventional demand for a solution to this problem.

In addition, since the above construction method is constructed by incorporating pre-formed heat insulating material, each component of the structure constructed on the wall surface is not integrated with this construction, and there is a gap between the components. As a result, condensation occurs in the gap due to moisture penetration and humidity, which deteriorates water resistance, durability,
There was also a fatal problem that the heat insulation effect was reduced by tA.

The present invention was made to solve the above-mentioned problems, and does not cause the insulation material to peel or fall off.
Moreover, it prevents the occurrence of condensation between the various structural members that make up the constructed structure, making it water resistant.

The purpose is to improve durability and heat insulation effect.

(Means for Solving the Problems) In order to achieve the above object and solve the above problems, the present invention has been made as an external wall insulation structure and a wall external insulation construction method. The external heat insulating structure is characterized by a frame 2 attached to the top of the wall 1;
A core material 6 is made to protrude from at least one side of a heat insulating body 5 made of an organic heat insulating material, and the core material 6 on one side of the heat insulating body 5 is attached to the frame via an adhesive 4 so that the core material 6 on one side of the heat insulating body 5 faces upward. A heat insulating material 7 bonded to the upper surface of the wall l inside the body 2, and a core material 6 protruding from one side of the heat insulating material body 5.
In order to embed the heat insulating material 7, an inorganic coating material is coated on one side of the heat insulating material 7, and the base layer 8 is formed on one side of the heat insulating material 7.

The feature of the external insulation construction method is that a frame body 2 is attached to the upper surface of the wall surface l, an adhesive 4 is applied to the upper surface of the wall surface 1 within the frame body 2, and then an organic heat insulating material is A heat insulating material 7 having a core material 6 protruding from at least one surface of the heat insulating material body 5 is attached to the frame via the adhesive 4 so that the core material 6 on one surface of the heat insulating material body 5 faces upward. 2, and then, in order to bury the core material 6 protruding from one side of the heat insulating body 5, an inorganic coating material is applied to one side of the heat insulating material 7 to form the heat insulating material. Material 7
The base layer 8 is integrally formed on one side of the base layer 8.

(Function) That is, the heat insulating material 7 is bonded to the wall surface l via the adhesive 4, and in order to embed the core material 6 protruding on one side of the heat insulating material 7, an inorganic coating is applied to the negative side of the heat insulating material 7. Since the base layer 8 is formed integrally with the coated material, there is no possibility of peeling or falling off between the heat insulating material 7 and the base layer 8, and there is no chance of peeling or falling off of the heat insulating material 7 or base layer 8 from the wall surface l. There is no chance of it falling off.

In addition, since each component is completely integrated by adhesion through the adhesive 6 or by painting with an inorganic coating material, there are no gaps between the components, and therefore, there is no gap between the components. This also prevents moisture from penetrating.

Furthermore, because of the construction method described above, the heat insulating material is installed along the inside of the frame 2, and the inorganic coating material is coated without protruding from the inside of the frame 2, so that the heat insulating material In addition to being easy to install and apply inorganic coating materials, the above-mentioned adhesives can be easily applied.

Since the construction is done by painting, the construction can be done without requiring any joint members or the like.

(Example) Regarding the embodiments of the present invention, first, an embodiment of a method for performing external insulation on a wall surface will be described.

First, as shown in FIG. 1, a substantially rectangular frame 2 made of artificial wood made of plastic foam reinforced with long glass fibers is attached to a wall surface 1 by driving anchors 3.

Next, as shown in FIG. 2, after applying an acrylic copolymer resin adhesive 4 to the inside of the frame 2 of the wall surface 1, as shown in FIG. A substantially wire-mesh-shaped core material 6 is passed through the heat insulating body 5, and one end 6a side of the core material 6 is made to protrude to one side of the heat insulating material body 5 by a certain distance, and the other end 6b side of the core material 6 is A heat insulating material 7 is formed by exposing the heat insulating material 7 on the other side of the heat insulating material body 5, and one end 6a of the core material 6 protrudes from the heat insulating material 7.
With one side facing the top, apply the adhesive 4 as shown in Figure 4.
It is adhered to the upper surface of the wall surface l through.

At this time, the other end 6b of the core material 6 exposed on the other side of the heat insulating material 7 is embedded in the adhesive 4, and therefore, after the adhesive 4 has hardened, it is simply a heat insulating material. Not only is the material 7 bonded to the wall surface 1 via the adhesive 4, but the heat insulating material 7 and the adhesive 4 are integrated through the other end 6b of the embedded core material 6, and as a result, the heat insulating material 7 and This means that the wall surface 1 is integrated with the wall surface l.

Next, one end 6a of the core material 6 protruding from one side of the heat insulating material 7
By coating the upper surface of the heat insulating material 7 with mortar containing a fiber material so as to bury the side thereof, as shown in FIG. It is integrally formed on the top surface.

In this case, since the mortar is coated so that one end 6a of the core material 6 is buried, the buried core material 6
The base layer 8 is integrated with the heat insulating material 7 via one end 6a of the base layer 8.

Thereafter, as shown in FIG. 6, a waterproof sheet 9 as a finishing material is attached to the upper surface of the base layer 8.

In this way, external insulation of the wall surface 1 is carried out in a certain space of the wall surface l surrounded within the frame 2,
The external insulation construction of the wall surface is completed by performing this construction in the same way in other spaces of the wall surface l.

In the construction method described above, the heat insulating material 7 as a molded product is glued or coated with mortar in a certain space of the wall surface 1 surrounded by the frame 2, so the heat insulating material The mortar and mortar do not protrude from the frame 2, and the entire construction work can be performed very easily.

Next, one embodiment of the external wall insulation structure of the present invention will be described.

That is, the wall external insulation structure as an example is as follows:
As shown in FIG. 6, a frame body 2 is attached to the upper surface of a wall surface 1 by driving anchors 3, and an acrylic copolymer resin adhesive 4 is adhered to the upper surface of the wall surface 1 within the frame body 2. A substantially wire-mesh-shaped core material 6 is passed through the heat insulating body 5 made of pre-formed urethane, and one end 6a of the core material 6 is made to protrude by a certain distance from one side of the heat insulating body 5, and the core The other end 6b of the core material 6 is exposed on the other surface of the heat insulating material body 5, and the other end 6b of the core material 6 is embedded in the adhesive 4. A heat insulating material 7 bonded to the upper surface of the wall surface 1 via the adhesive 4, and one end 6a of the core material 6 protruding to one side of the heat insulating material 7.
Base N formed by coating mortar to bury
8 and a waterproof sheet 10 provided on the upper surface of the base layer 8.

That is, adhesion 9 of the above-mentioned heat insulating material 7 via adhesive 4
Since they are integrally formed by coating with mortar, etc., almost no gaps are formed between these constituent members, such as the heat insulating material 7 and the base layer 8, as well as the wall surface 1. Therefore, condensation due to moisture penetration into the structure does not occur.

In particular, since the surface finishing material is formed of the waterproof sheet 9, penetration of moisture can be more reliably prevented.

Furthermore, the core material 6 protruding from the heat insulating body 5 serves as the framework of the structure, increasing the strength of the entire structure.

In the above embodiment, the frame 2 is made of artificial wood made of plastic foam reinforced with long glass fibers, so the frame 2 itself is lightweight and convenient to handle, and has excellent strength and heat resistance. However, the material of the frame 2 is not limited to these materials.

Furthermore, the means for attaching the frame 2 to the wall surface 1 is not limited to the method of driving the anchors 3 in the embodiment.

Incidentally, it is also possible to interpose a so-called caulking material on the lower surface of the frame 2.

Furthermore, the shape of the frame 2 is also not limited.

Furthermore, the material of the adhesive 4 is not limited to the acrylic copolymer resin adhesive of the embodiment.

In short, it is sufficient as long as the heat insulating material 7 can be bonded to the wall surface 1.

Further, the material of the heat insulating body 5 is not limited to the urethane of the embodiment, but any organic heat insulating material may be used.

Furthermore, the shape of the core material 6 is not limited to the wire mesh shape of the embodiment, and the material thereof is not limited to the iron material of the embodiment.

Further, in the above embodiment, one end 6a of the core material 6 is made to protrude by a certain distance toward one surface side of the heat insulating material body 5, and the other end 6b of the core material 6 is
is formed to be exposed on the other surface of the heat insulating material body 5, but the degree of protrusion of the core material 6 is not limited to this. For example, the protrusion of both ends 6a of the core material 6, In addition, the core material 6 may protrude only on one side of the heat insulating material 7 and not on the other surface. It is sufficient that the heat insulating material 7 is constructed by making the core material 6 protrude.

Further, the type of coating material that is coated on the upper surface of the heat insulating material 7 to form the base layer 8 is not limited to the mortar used in the embodiment, and may be, for example, cement or the like. It is sufficient if an inorganic coating material is used.

Furthermore, the means for applying this inorganic coating material is not limited to the coating method described in this embodiment.

Furthermore, in the above embodiment, the waterproof sheet 9 is used as a finishing material.
Although the above-mentioned favorable advantages were obtained by using the above-mentioned finishing material, the type of finishing material is not limited to this example. Further, providing finishing is not an essential step for the present invention.

(Effects of the Invention) Since the present invention has the above characteristics, it has achieved the following effects.

(b) That is, the heat insulating material is bonded to the top surface of the wall via adhesive, and the top surface of the heat insulating material is coated with an inorganic coating material in order to bury the core material that protrudes on the top surface of the heat insulating material. Since the base layer is formed and constructed as one piece, it prevents the insulation from peeling off or falling off the wall, and
By embedding the core material, the base layer is prevented from peeling off or falling off from the insulation material, and therefore each component does not peel or fall off from each other, which has previously been a problem with external insulation construction methods for walls. This has resulted in a particularly remarkable effect in that peeling and falling off of structures such as these can be almost completely prevented.

Furthermore, the core material protruding from the heat insulating material not only strengthens the bonding force between the heat insulating material and the base layer, but also serves as the framework of the entire structure, thereby increasing the strength of the entire structure.

(b) Also, since each component is integrated by adhering heat insulating material and painting with an inorganic coating material without using a joint member, there are no gaps between these components, and the follower ζ No condensation occurs inside the external heat insulating structure due to the penetration of water or moisture, and as a result, the heat insulating effect, water resistance, and durability are significantly improved compared to conventional structures.

(C) Furthermore, in the construction method of the present invention, first, after the frame is installed, a heat insulating material or an inorganic coating material is applied to the limited wall space within the frame. Therefore, the construction work itself can be carried out very efficiently,
However, since there is no need for joining work using joint members as in the past, there is an advantage that the overall construction work is much easier than in the past.
