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 to the top of the insulation material. There is a method of construction by painting etc.

(Problems to be Solved by the Invention) However, in this construction method, the insulation material is joined to the wall surface by driving anchor bolts, so the connection between the two is not perfect, and therefore, the insulation material Another problem has arisen in that there is a risk that the material may peel off or fall off the wall surface.

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

Furthermore, 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 due to this construction, and its structure is A fatal problem arises in that gaps are formed between the members, and as a result, moisture permeates and condensation occurs in the gaps due to humidity, which impairs water resistance, durability, and heat insulation effects.

The present invention was made to solve the above-mentioned problems, and it does not cause peeling or falling off of the insulation material, and also prevents the occurrence of dew condensation between the constituent members of the structure being constructed. The purpose is to prevent this and improve water resistance, durability, and heat insulation effects.

(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 having a frame 2 attached to the upper surface of the wall 1, and a heat insulating layer 5 formed by coating the upper surface of the wall 1 within the frame 2 with an organic heat insulating material. A first base layer 7 formed by coating the upper surface of the heat insulating layer 5 with an inorganic coating material, and a second base layer 9 formed by coating the upper surface of the first base layer 7 with an inorganic coating material. are formed integrally within the frame 2, and a plurality of anchors 4, ... are driven into the wall surface 1 so as to penetrate at least the heat insulating layer 5 and the first base layer 7, Moreover, a mesh 8 is provided between the first base layer 7 and the second base layer 9 to be bound to the anchor 4.
The reason is that it becomes an intervention.

In addition, the feature of the external insulation construction method is that the wall surface 1
A frame body 2 is attached to the upper surface of the frame body 2, and a plurality of anchors 4,... are driven into the upper surface of the wall surface 1 within the frame body 2,
Next, an organic heat insulating material is coated on the upper surface of the wall surface 1 into which the anchors 4 have been driven, and a heat insulating layer 5 is formed within the frame 2 on the upper surface of the wall surface 1. The insulation layer 5 is coated with an inorganic coating material.
A first base layer 7 is formed on the upper surface of the first
The anchors 4 are made to protrude outward from the upper surface of the base layer 7, and then the net-like body 8 is placed on the upper surface of the first base layer 7 while being bound to the anchors 4 protruding from the upper surface of the first base layer 7. Then, the reticular body 8
The second base layer 9 is integrally formed on the top surface of the first base layer 7 by applying an inorganic coating material to the top surface of the first base layer 7.

(Function) In other words, since the construction method is as described above, the above-mentioned heat insulating material, inorganic coating material, etc. are coated within the frame 2 without protruding from the frame 2 that is initially installed, and therefore the insulation When the wood and the inorganic coating material dry, a heat insulating layer 5, a first base layer 7, and a second base layer 9 are formed along the frame 2.

Also, an anchor 4 is driven into the wall surface 1 in advance,
After the formation of the heat insulating layer 5 and the first base layer 7, a net-like body 8 is installed, and the net-like body 8 is attached to the anchor 4.
This bundling reliably prevents the net-like body 8 from coming off. Therefore, even if the second base layer 9 is subsequently formed on the upper part of the net-like body 8, the net-like body 8 bound to the anchors 4 serves as a framework, increasing the strength of the constructed structure.

Further, in the structure of the present invention, a heat insulating material, an inorganic coating material, etc. are coated within the frame 2 to form a heat insulating layer 5, a first base layer 7, and a second base layer 9 as described above. Therefore, each component that makes up these structures is integrated, and no gaps or the like occur between the components.

(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, a large number of anchors 4,...
Type in.

Next, by spraying a heat insulating material made of urethane on the top surface of the wall surface 1 in the frame body 2, a heat insulating layer 5 is integrally formed on the top surface of the wall surface 1 as shown in FIG. Form. In this case, the heat insulating material is coated so that the anchors 4, .

Next, a mortar containing fiber material is applied to the upper surface of the heat insulating layer 5 via an acrylic copolymer resin adhesive 6, and as shown in FIG. A first base layer 7 is integrally formed on the upper surface of the heat insulating layer 5. At this time as well, the heat insulating material is applied so that the anchors 4 protrude from the first base layer 7.

In this case, since the adhesive 6 is interposed between the first base layer 7 and the heat insulating layer 5, the first base layer 7 can be bonded to the heat insulating layer 5 more reliably and firmly.

Next, as shown in FIG. 5, the net-like body 8 is placed on the upper surface of the first base layer 7 while being tied to the anchors 4, .

Next, by coating the upper surface of the first base layer 7 with mortar containing a fiber material through the network 8, a second base layer 9 made of the mortar is applied to the upper surface of the first base layer 7, as shown in FIG. It is integrally formed on the upper surface of the first base layer 7. In this case, the mortar is applied so that the surface of the second base layer 9 substantially coincides with the head of the anchor 4 and substantially the entirety of the anchor 4 is covered.

Thereafter, as shown in FIG. 7, a waterproof sheet 10 as a finishing material is attached to the upper surface of the second base layer 9.

In this way, the external insulation of the wall 1 is carried out in a certain space of the wall 1 surrounded by the frame 2, and this construction is carried out in the same way in other spaces of the wall 1 one after another. External insulation work on the wall is now complete.

In the construction method described above, the insulation material and mortar are painted in a certain space of the wall surface 1 surrounded by the frame body 2, so the insulation material and mortar protrude from the frame body 2. The heat insulating layer 5, the first base layer 7, and the second base layer 9 are formed by subsequent drying without drying.
etc. can be formed very easily, and as a result, 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, as shown in FIG. 7, the external heat insulating structure for a wall as an example includes a frame 2 attached to the upper surface of the wall 1 by driving anchors 3, and the A plurality of anchors 4, ... driven into the upper surface of the wall surface 1, a heat insulating layer 5 formed by coating a heat insulating material made of urethane on the upper surface of the wall surface 1 into which the anchors 4 were driven, and the heat insulating layer 5.
A first base layer 7 formed by applying mortar via an acrylic copolymer resin adhesive 6 to make the anchors 4, . . . protrude from the upper surface of the first base layer 7; A net-like body 8 installed on the upper surface of the first base layer 7 to be bound to the anchor 4, and a second base layer formed by applying mortar to the upper surface of the first base layer 7 through the net-like body 8. 9 and a waterproof sheet 10 provided on the upper surface of the second base layer 9.

That is, since the heat insulating layer 5, the first base layer 7, and the second base layer 9 are formed by spraying the heat insulating material, coating with mortar, etc., the heat insulating layer 5, the first base layer 9, which are these constituent members, Base layer 7, and second layer
Almost no gaps are formed between the base layers 9. 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 10, penetration of moisture can be more reliably prevented.

Furthermore, the mesh body 8 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 body 2 is not limited to these materials.

Furthermore, the means for attaching the frame body 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.

Further, the number of anchors 4 to be driven into the wall surface 1 is not critical, as long as a plurality of anchors 4, . . . are driven into the portion of the wall surface 1 surrounded by the frame 2.

Further, the material of the heat insulating material coated on the upper surface of the wall surface 1 is not limited to the urethane of the embodiment, but any organic heat insulating material may be used.

Further, the means for applying the heat insulating material to the wall surface 1 is not limited to the method of spraying as in the embodiment, but may also be a means of applying it with a trowel or the like. In short, it is sufficient that the heat insulating layer 5 is integrally formed on the upper surface of the wall surface 1 by coating with a heat insulating material.

Furthermore, in this embodiment, the first base layer 7 is formed on the upper surface of the heat insulating layer 5 via the adhesive 6;
Although the above-mentioned favorable advantages have been obtained, the provision of the adhesive 6 is not a condition.

Furthermore, the type of coating material applied to the upper surface of the heat insulating layer 5 to form the first base layer 7 is not limited to the mortar of the embodiment, and may be, for example, cement or the like. In short, it is sufficient as long as an inorganic coating material is used.

Similarly, the material of the second base layer 9 is not limited either, as long as it is made of an inorganic coating material.

Further, in the above embodiment, the waterproof sheet 10 was used as the finishing material, so that the above-mentioned preferable advantages were obtained, but the type of finishing material is not limited to this embodiment. Further, providing a finishing material is not an essential step for the present invention.

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

(b) In other words, the heat insulating layer, the first base layer, the second base layer, etc. are integrally formed and constructed on the upper surface of the wall by applying heat insulating materials and inorganic paint materials. Since each component is integrated to form a single layer, and there are no gaps between these components, there will be no condensation inside the external heat insulating structure due to moisture penetration. As a result, the heat insulation effect, water resistance, and durability are significantly improved compared to conventional products.

(b) A more important point is that since the net-like body is interposed between the first base layer and the second base layer, this net-like body acts as a framework and has the effect of increasing the strength of the entire structure. .

In particular, when this net-like body is installed on the first base layer, it is tied to anchors that have been driven into the wall surface in advance, so it goes without saying that after the second base layer is formed and the net-like body is buried. In addition, even when the net-like body is installed, the net-like body does not peel off or fall off, which has the effect of ensuring the strength of the structure is maintained and making construction work such as installing the net-like body easier. .

Therefore, the present invention has a particularly remarkable effect in that peeling and falling off of structures such as heat insulating materials, which has been a problem in the past, especially in external wall insulation construction methods, can be almost completely prevented.

(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 performed very efficiently, and 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.

Moreover, the anchors that are driven into the wall surface in advance to bind the mesh body can be driven in a certain space within the frame, so it is relatively easy to select the anchoring position, and the driving work itself is also easy. There is a practical benefit in that it is easy to do.
