Description

High load thermal bridge blocking type external insulation system with improved adhesion performance and its construction method {HEAT BRIDGE PREVENTION TYPED HIGH LOAD EXTERIOR INSULATION FINISH SYSTEM OF CONCRETE WALL WITH IMPROVED ADHESION ABILITY AND THE CONSTRUCTION METHOD THEREOF}

The present invention relates to a thermal bridge blocking type external insulation system for high loads with improved adhesion performance. More specifically, in an external insulation structure (external insulation system) constructed by attaching insulation to the outside of the structure wall, the thermal bridge phenomenon occurs. It can block the outside of the structure wall and effectively secure the adhesion performance of the insulation material, and can effectively support the load even when the load from heavy finishing materials is added. A high-load thermal bridge blocking type external insulation system with improved adhesion performance and its construction. It's about method.

Typically, an insulation structure in a structure refers to a structure that prevents heat from being released to or from the outside of the structure, and is currently promoting zero energy and zero carbon building structures nationwide for the purpose of preventing global warming. It is one of the element technologies for

Figures 1a, 1b and 1c show examples of the insulation structure of a wall of a conventional structure.

That is, the insulation structure of the structure can be classified into an inner insulation structure, a mid-insulation structure, and an outer insulation structure, as shown in FIGS. 1A, 1B, and 1C, depending on the location where the insulation material 10 is installed.

First, the internal insulation structure is a structure in which the insulation material 10 is installed on the inside of the structure wall 20 (concrete), as shown in Figure 1a. It has the advantage of being easy to construct because the work space inside the structure is already secured, but the structure has the advantage of being easy to construct. A thermal bridge phenomenon may occur in which heat is transferred and lost to the structural wall side (20) connected to the concrete slab (30),

There is a disadvantage that energy is lost due to heating, etc., and condensation may occur locally.

It is a medium-insulation structure that selectively combines the advantages and disadvantages of such an internal insulation structure and inserts and installs insulation material in the middle of the structure wall.

In other words, as shown in FIG. 1b, the medium-to-medium insulation structure is formed so that the structural walls 20 are integrated on both sides of the insulation material 10 to prevent energy loss by the insulation material 10, and does not take special finishing for the insulation material into consideration. It has the advantage of not having to be used.

However, in the construction process of this medium-insulation structure, the structural wall 20 and the insulation material 10 must be constructed as one piece, so construction is complicated when using Euroform, gangform, etc., and the construction cost of the medium-insulation wall is higher compared to the internal insulation structure. There was a problem that it was a factor in raising the temperature, and there was a problem that thermal bridge phenomenon could occur due to the form-tie for formwork penetrating the insulation material during the construction process.

Next, the external insulation structure is an insulation structure in which the insulation material 10 is fixedly installed on the outside of the structural wall 20, as shown in FIG. 1C, and has the advantage of excellent insulation performance, but has the disadvantage of being difficult to construct and maintain.

That is, in the case of an external insulation structure, energy due to heating, etc. transmitted through the concrete slab 30 to the structure wall 20 is blocked by the insulation material 30 installed on the outside of the structure wall 20, so energy loss can be blocked. Although there is a structure,

In order to fix and install the insulation material 30 on the outside of the structure wall 20, a work space is required for workers to fix and install the insulation material 30 on the structure wall 20 from the outside of the structure wall. Therefore, a work space is required by installing separate scaffolding, etc. It is essential to secure

Even when installing the insulation material 30 on the outside of the structural wall 20, sufficient adhesion performance must be secured, but if construction management is not performed properly, there is a problem in that damage occurs.

Accordingly, it can be seen that in external insulation structures, it is especially important to determine how to securely install the insulation material on the outside of the structure wall and effectively secure insulation performance by preventing thermal bridges from occurring during the attachment process.

Regarding how to fix and install the insulation material on the outside of the structure wall, FIG. 1D shows an example of a method of attaching the insulation material 30 to the outside of the structure wall 20 in a conventional external insulation structure.

That is, a conventional mechanical bonding and attachment method has been introduced, and according to FIG. 1D, it can be seen that a fixed anchor 40 is used to bond the insulation material 10 to the outside of the structure wall 20.

That is, the fixed anchor 40 penetrates the insulation material 30 so that the tip is inserted and anchored to a certain depth on the outside of the structure wall 20,

It can be said to be a joining method in which the fixed anchor 40 penetrates the insulation material 30 and is mechanically pressed to the outside of the structural wall 20.

Accordingly, there is an advantage that attachment performance can be secured depending on the number of fixed anchors (40) installed, but the work of fixing and installing the fixed anchors (40) on the outside of the wall of a high-rise structure by manpower requires a hole for fixing the fixed anchors (40) in the structure. Because it has to be formed on the outside of the wall, workability is low, so construction and quality control are not easy.

In addition, there was a problem in that it was difficult to sufficiently secure the insulation performance of the insulation material 30 due to the thermal bridge phenomenon. In other words, there is a limitation that energy loss problems inevitably occur, such as energy due to heating, etc. being released to the outside of the structure wall through the fixed anchor 40.

This is a problem that inevitably occurs as the fixed anchor (40) is anchored to the outside of the structure wall, and even if the fixed anchor (40) is changed to a material that can prevent thermal bridges, such as FRP, the thermal bridge phenomenon itself cannot be avoided. There will be no more.

Accordingly, an attachment method is used to prevent constructability and workability problems and thermal bridge phenomenon caused by the fixed anchor 40.

Figures 1e and 1f show an example of a method of attaching the insulation material 10 to the outside of the wall 20 of a conventional structure using an attachment method and an example photo of the insulation material being installed due to loss of the attachment area of the insulation material.

Looking at the method of attaching the insulation material 10 to the outside of the conventional structural wall 20,

As shown in Figure 1e, for example, polymer mortar 50, which is a ready-made product, is applied (front-mounted) to the entire outside of the structure wall 20 and attached, or

It can be seen that a method of applying and attaching polymer mortar 50 to only a certain portion of the insulating material 10 (hard attachment) is used.

In other words, the attachment method ensures the insulation performance of the insulation material depending on the attachment performance between the polymer mortar 50 and the outside of the structure wall 20.

When wind load acts on the insulation material, it is known that the attachment strength that can be secured by the above attachment method between the insulation material (10) and the outside of the structure wall (20) is only about 0.1 MPa at most, so when the wind load occurs above the standard value, the attachment strength is The insulation material 10 due to corrosion protection has a limit in which it cannot help but fall off from the structural wall.

In addition, as shown in Figure 1f, the attachment method has the problem that it is not easy to secure workability and constructability, resulting in construction defects due to loss of attachment area (A).

For example, the attached external insulation structure requires polymer mortar to be applied at a thickness of about 10 to 20 mm on 1800 It is known that % adhesion area loss occurs.

However, due to poor construction and quality control, there is a loss in the attachment area, and it is inevitable that many accidents will occur where the insulation material falls off from the structural wall in the external insulation structure due to wind load, etc.

In addition, when the insulation material 10 is installed using an attachment method, the load due to heavy finishing materials such as external stone on the structural wall 20 is often added.

In order to secure attachment performance, anchors, etc. for guide materials for fixing heavy finishing materials are used, but due to low constructability, construction costs inevitably increase, so there are cases where they are omitted at the site. Therefore, in external insulation structures, the attachment method is used for construction and quality control. If not done properly, there was an inevitable problem that a safety accident would occur in the historical structure, as shown in Figure 1f.

[High-load thermal bridge blocking type external insulation system with improved adhesion performance (100)]

Figures 2a, 2b, and 2c show an example configuration, combination view, and installation example of the high-load thermal bridge blocking type external insulation system 100 with improved adhesion performance of the present invention, and Figure 2d shows the thermal bridge blocking phenomenon of the present invention. This diagram shows an example of installing an insulation connection pin.

First, referring to Figure 2c, the high-load thermal bridge blocking type external insulation system 100 with improved attachment performance can be said to be an external insulation structure that secures insulation performance by attaching an insulation material 220 to the outside of the structure wall 210,

In particular, it can be said to be a high-load thermal bridge blocking type external insulation system (100) with improved adhesion performance effective for high-rise structures affected by wind loads, etc.

First, the three-dimensional adhesive plate 110 is simply attached to the outside of the structure wall 210 using adhesive 120, as shown in FIG. 2C,

As shown in FIG. 2C, the tip of the insulating material connecting pin 130 is fastened and fixed directly to the lower plate 112 of the three-dimensional adhesive plate 110 at a certain depth, so that there is a constant flow from the three-dimensional adhesive plate 110 to the outside of the structure wall 210. extend the length,

The insulation material 220 is joined so that the back surface of the insulation material 220 is in contact with the lower plate 112 of the three-dimensional adhesive plate 110 through the head of the insulation connection pin 130, so that the insulation material 220 is attached to the structure wall. It is spaced apart from (210) by the thickness of the lower plate 112 of the three-dimensional adhesive plate 110,

An acupressure tool 140 including an acupressure plate 141 and an acupressure nut 142 is set on the head of the insulator connection pin 130 protruding from the surface of the insulator 220 to attach the insulator 220 to the structure wall 210. An attachment method is used in which it is fixedly installed on the outside of the machine using acupressure.

It can be seen that, unlike the conventional attachment method, no application work is required like polymer mortar, which is a mechanical bonding method, thereby ensuring constructability and workability.

Accordingly, referring to Figure 2c, the three-dimensional adhesive plate 110 is first fixed to the outside of the structure wall 210 with adhesive 120, and the tip of the insulation connection pin 130 is fastened and fixed only to the three-dimensional adhesive plate 110. Because it does so, it is possible to eliminate factors that would otherwise cause thermal bridge phenomenon,

The insulation connection pin 130 allows the insulation material 220 to be pressed by the pressure tool 140 and pressed against the outside of the structure wall 210, thereby effectively preventing tensile failure of the insulation material 220 due to out-of-plane wind load, etc. It becomes,

In addition, the in-plane shear against the vertical load and bending behavior acting on the insulation material 220 is controlled by the adhesive force of the adhesive 120, so that sufficient adhesion strength between the insulation material 220 and the outside of the structure wall 210 can be secured. ,

The insulation material 220 can be prevented from falling off even if wind load or additional load occurs from the structure wall 210.

As shown in Figure 2c, it is a high-load thermal bridge with improved adhesion performance in the sense that it allows installation of a heavy finishing material 240, such as an exterior finishing panel, to the pressure tool 140 installed on the three-dimensional adhesive plate 110 using a bracket 230. It is referred to as a blocking external insulation system (100).

In addition, referring to FIG. 2C, in addition to installing the three-dimensional adhesive plate 110 at the edge of the insulation material 220, an additional adhesive plate ( 110a) will be used more,

This additional adhesive plate 110a is formed only of the lower plate 112 and fastens the tip of the insulating material connecting pin 130 directly only to the additional adhesive plate 110a, thereby eliminating other factors that may cause thermal bridge phenomenon. is the same.

To this end, the high-load thermal bridge blocking type external insulation system 100 with improved adhesion performance of the present invention includes a three-dimensional adhesive plate 110, adhesive 120, and insulation connection pin, as shown in FIGS. 2A, 2B, 2C, and 2D. (130) and includes an acupressure device (140).

First, the three-dimensional adhesive plate 110 has a cross shape and a lower plate 112 that is bonded to the outside of the structural wall 210 made of concrete with an adhesive 120, as shown in FIGS. 2A, 2B, 2C, and 2D. A three-dimensional plate member in which the web 113 is integrated and has an installation depth sufficient to accommodate the thickness of the insulation material 220,

Unlike the prior art, the insulation connecting pin 130 is not inserted to a certain depth on the outside of the structure wall 210 and is not fixed,

While being fixed to the inside of the bottom plate 112 of the three-dimensional adhesive plate 110 at a certain depth, the insulation material 220 is attached to the outside of the structure wall 210 by the adhesive force of the adhesive 120 to maintain a predetermined adhesive strength. It plays a role in securing .

In addition, referring to FIGS. 2A, 2B, 2C, and 2D, the three-dimensional adhesive plate 110 is installed at an area where the corners of the insulation material 220 are gathered so that each corner of the adjacent insulation material 220 is connected to the structure wall. It can be seen that it is gathered and attached to the outside of (210).

Accordingly, the lower plate 112 is formed of a plate member such as a square that is directly bonded to the outside of the structural wall 210 with an adhesive 120, as shown in FIGS. 2A, 2B, 2C, and 2D, and is an insulating material to be described later. A female thread portion 111 is formed so that the male thread portion 133 formed at one end of the connecting pin 130 is fastened and fixed to the surface at a certain depth.

In addition, the web 113 is, for example, a cross-shaped flange extending from the surface of the lower plate 112, as shown in FIGS. 2A, 2B, 2C, and 2D, and is applied to the lower plate 112 through acupressure delivered by the acupressure tool 140. ) so that the insulation material 220, which is fixedly installed, is more stably bonded to the outside of the structure wall 210,

The load transmitted by the heavy structure can also be effectively supported, and the thickness of the web 113 is made to correspond to the thickness of the insulation material 220, so that the insulation material 220 is sandwiched between the lower plate 112 and the acupressure tool 140. I will let you lose.

It can be seen that the bottom plate 112 and the web 113 of this three-dimensional adhesive plate 110 are formed in an integrated form made of plastic material so that workers can work with a light weight.

Since one insulating material 220 is formed in a square plate shape with a certain size (e.g., 900 mm (width) × 1800 mm (height width) × 150 mm (thickness)), the three-dimensional adhesive plate 110 on the back of the insulating material 220 is at least It is attached by adhesive force using adhesive 120 to the outside of the structure wall 210 to ensure the required attachment performance with the number of,

2A, 2B, 2C, and 2D, it can be seen that four three-dimensional adhesive plates 110 are placed on one insulator 220 at the corners of the insulator 220.

In addition, in addition to installing the three-dimensional adhesive plate 110 at the corner of the insulation material 220, an additional adhesive plate 110a that allows the insulation material 220 to be additionally attached to the outside of the structure wall 210 can be used. You can.

This additional adhesive plate 110a is formed only of the lower plate 112, and is first used to additionally bond the insulation material 220 installed by the three-dimensional adhesive plate 110 to the outside of the structure wall 210. In contrast to , it can be seen that the web 113 does not exist.

Accordingly, after bonding the insulation material 220 to the outside of the structure wall 210 using the three-dimensional adhesive plate 110, an acupressure tool 140 is installed on the head of the insulation connection pin 130 installed on the lower plate 112 to provide additional acupressure. so that it can be attached.

That is, one end of the insulation connecting pin 130 is formed with a male thread portion 133 to be fastened to the female thread portion 111 only on the surface of the lower plate 112 of the additional adhesive plate 110a, and is also fastened to the other end. The portion 134 is formed so that the insulation material 220 penetrated by the pressure plate 141 is pressed against the rear surface of the three-dimensional adhesive plate 110.

Next, the adhesive 120 is applied to the bottom plate ( 112) is adhered by adhesive force so that the insulation material 220 can be fixedly installed by pressing pressure on the three-dimensional adhesive plate 110 and the additional adhesive plate 110a using the insulation connecting pin 130 and the pressure tool 140. It plays a role.

This adhesive 120 uses, for example, a resin-based adhesive, and it has been confirmed that the adhesive strength is much greater compared to the conventional mechanical bonding method using fixed anchors and the attachment method using polymer mortar, which is difficult to construct and work quality. The invention uses adhesive 120 in the attachment method.

As a result, the adhesive 120 resists the in-plane shear due to the vertical load and bending behavior of the external insulation system, rather than attaching the insulation material 220 directly to the outside of the structural wall 210.

The insulation material 220 is attached to the three-dimensional adhesive plate 110 and the additional adhesive plate 110a, which are bonded to the outside of the structure wall 210 by the adhesive force of the adhesive 120, using the insulation connection pin 130. Since it is attached to the outside, constructability and workability can be sufficiently secured.

Next, the insulation connecting pin 130 attaches the insulation material 220 to the three-dimensional adhesive plate 110 and an additional adhesive plate attached to the outside of the structure wall 210, as shown in FIGS. 2A, 2B, 2C, and 2D. By pressing and installing fixedly at (110a), it plays a role in preventing tensile destruction of the insulation material 220 due to out-of-plane wind load, etc.

As a result, the insulation material 220 of the present invention is directly fixed to the three-dimensional adhesive plate 110 and the additional adhesive plate 110a by the insulation connecting pin 130, and the three-dimensional adhesive plate 110 and the additional adhesive plate 110a are It can be seen that it is installed using a method in which the adhesive 120 is used to adhere to the outside of the structure wall 210 by adhesive force.

According to FIG. 2D, this insulating material connecting pin 130 includes a pin body portion 131 and a head pin 132.

It is formed to be fastened and fixed to the female screw portion 111 formed in depth, and a fastening portion 134 is formed at the other end so that the insulation material 220 is pressed by the acupressure plate 141.

Since this pin body portion 131 is installed by directly fastening only to the three-dimensional adhesive plate 110 and the additional adhesive plate 110a, workability is improved, and since it is not directly inserted into the outside of the structure wall 210, a thermal bridge phenomenon occurs. Preferably, one made of FRP material in the form of a rod can be used.

Next, as shown in FIG. 2D, the head pin 132 is temporarily fastened to the fastening portion 134 formed at the other end of the pin body portion 131 and is tapered into a wedge shape to facilitate penetration of the insulation material 220. will be.

By applying pressure to the additional adhesive plate 110a, it serves to effectively prevent tensile destruction of the insulation material 220 due to out-of-plane wind load, etc.

Accordingly, the acupressure device 140 includes an acupressure plate 141 and an acupressure nut 142, as shown in FIGS. 2A, 2B, 2C, and 2D.

First, the acupressure plate 141 is a circular plate that is inserted into the other end of the insulation connection pin 130 exposed through the insulation material 220 and installed in contact with the insulation material 220, as shown in FIGS. 2A, 2B, 2C, and 2D. It is formed by etc.

Next, the acupressure nut 142 is rotatably fastened to the fastening portion 134 of the other end of the insulation connection pin 130 exposed through the insulation material 220, as shown in FIGS. 2A, 2B, 2C, and 2D. As a result, the pressure plate 141 serves to apply pressure to the insulation material 220.

According to FIGS. 2A, 2B, 2C and 2D, it can be seen that the acupressure plate 141 is formed to correspond to the size of the lower plate 112, and it is preferable to use the same one as the lower plate 112. . In addition, there is no difference between the acupressure plate 141 installed at the edge of the insulation material 220 and the acupressure plate 141 used for the additional adhesive plate 110a.

According to Figure 2c, in the case of the high-load thermal bridge blocking type external insulation system 100 with improved adhesion performance, a bracket 230 is further installed on the acupressure plate 141, and a heavy finishing material such as an external finishing panel is installed on the bracket 230. 240) can be seen being installed more.

[Construction method of high-load thermal bridge blocking type external insulation system (100) with improved adhesion performance of the present invention]

Figures 3a, 3b and 3c show a flowchart of the construction method of the high-load thermal bridge blocking type external insulation system 100 with improved adhesion performance of the present invention.

The construction method of the high-load thermal bridge blocking type external insulation system 100 with improved adhesion performance of the present invention involves attaching the insulation 220 to the outside of the structure wall 210, using a three-dimensional adhesive plate 110 and an additional adhesive plate ( 110a) is first adhered to the outside of the structure wall 210 using adhesive 120,

A method of fixing and installing the insulation material 220 on the three-dimensional adhesive plate 110 and the additional adhesive plate 110a, which are bonded to the outside of the structure wall 210 by the adhesive force of the adhesive 120, while applying pressure using an acupressure tool 140. It can be said that

First, as shown in FIG. 3A, a plurality of three-dimensional adhesive plates 110 and additional adhesive plates 110a corresponding to the size of one insulator 220 are attached to the outside of the structure wall 210 using an adhesive 120, The insulation connecting pin 130 is fastened and fixed to the three-dimensional adhesive plate 110 and the additional adhesive plate 110a.

The outside of the structure wall 210 is exposed with concrete, and the insulation material 220 can be made of semi-incombustible material such as roxel board formed in the shape of a regular square plate.

This insulating material 220 may be formed to a certain size (e.g., 900 mm (width) × 1800 mm (vertical width) × 150 mm (thickness)), but its size and material are not otherwise limited.

Accordingly, it is desirable to first perform foundation work on the outside of the structural wall 210 exposed by the concrete so that workers can remove contaminants such as dust and ensure flatness.

Accordingly, when the base work is completed, the adhesive 120 of the present invention is first adhered to the outside of the structure wall 210.

This adhesive 120 can secure the required adhesion strength by using a resin-based adhesive, etc. For example, in the case of the insulation material 220 manufactured in 900 mm (width) × 1800 mm (vertical width) × 150 mm (thickness), Four three-dimensional adhesive plates 110 and three additional adhesive plates 110a are installed,

The adhesive 120 is applied to the area where the three-dimensional adhesive plate 110 and the additional adhesive plate 110a are located.

Accordingly, before the adhesive 120 is cured, the three-dimensional adhesive plate 110 and the additional adhesive plate 110a are adhered to the applied adhesive 120 to form the three-dimensional adhesive plate 110 and the additional adhesive plate ( 110a) is bonded by adhesive force, and for example, four three-dimensional adhesive plates 110 and three additional adhesive plates 110a are installed.

When the adhesive 120 is completely cured and a predetermined adhesive strength can be secured, the insulation connecting pin 130 is fastened and fixed to the three-dimensional adhesive plate 110 and the additional adhesive plate 110a.

A female thread 111 is formed at a certain depth on the surfaces of the three-dimensional adhesive plate 110 and the additional adhesive plate 110a, and a male thread 133 is formed on one end of the insulating material connecting pin 130,

The male threaded portion 133 of the insulation connecting pin 130 is fixed to the three-dimensional adhesive plate 110 and the female threaded portion 111 of the additional adhesive plate 110a by rotating it.

Accordingly, the insulation connecting pin 130 is fastened and fixed only to the three-dimensional adhesive plate 110 and the additional adhesive plate 110a and does not contact the outside of the structure wall 210, so that the insulation material 220 penetrates the insulation connecting pin 130. Even if installed, thermal bridge phenomenon due to energy loss that otherwise would cause energy leakage does not occur.

At this time, a head pin 132 made of steel, etc. is temporarily inserted into the other end of the insulation connecting pin 130.

Next, as shown in Figure 3b, the head pin 132 inserted into the other end of the insulating material connecting pin 130 fastened to the three-dimensional adhesive plate 110 and the additional adhesive plate 110a is removed, and the other end is exposed. The insulation material 220 is installed to penetrate.

That is, according to Figure 3b, one end of the insulation connecting pin 130 is fastened and fixed to the three-dimensional adhesive plate 110, and the other end is inserted by the head pin 132, and the head pin 132 is fixed to the three-dimensional adhesive plate 110. Since it is made of steel and has a wedge shape, it is easy to install the insulation material 220 through it.

Accordingly, using the head pin 132, the insulation material 220 is installed so that the back surface of the insulation material 220 is in contact with the surface of the three-dimensional adhesive plate 110 and the additional adhesive plate 110a so that the insulation material 220 penetrates the insulation connection pin 130. , At this time, the extension length of the pin body portion 131 of the insulating material connecting pin 130 may be determined so that the head pin 132 is exposed to the surface of the installed insulating material 220.

At this time, it can be seen that the corner portion of the insulation material 220 is installed in the three-dimensional adhesive plate 110, and the central portion of the insulation material 220 is installed in contact with the additional adhesive plate 110a.

As a result, as shown in FIG. 3C, the head pin 132 inserted into the other end of the insulation connecting pin 130 is removed and the insulation material 220 is attached to the three-dimensional adhesive plate 110 and the additional adhesive plate 110a using the acupressure tool 140. ), the insulation material 220 is attached to the outside of the structure wall 210 by applying pressure and fixing it.

Since the head pin 132 is intended to be installed through the insulation material 220, it is removed and the fastening portion 134 is exposed at the other end of the exposed insulation connection pin 130, so that the acupressure plate 141 of the acupressure device 140 is first connected. Set to penetrate the fastening portion 134 and contact the surface of the insulation material 220,

The acupressure nut 142 is fastened to the fastening part 134 through which the acupressure plate 141 is installed to adhere the insulation material 220 to the three-dimensional adhesive plate 110 and the additional adhesive plate 110a, ultimately attaching the insulation material 220 to the structure wall. (210) It can be attached to the outside, and it is desirable to install a cap on the acupressure nut 142 to prevent it from being exposed to the outside and corroded.

Next, as shown in Figure 3c, the heavy finishing material 240 is installed on the acupressure plate 141 of the acupressure tool 140 using the bracket 230, and can be connected to each other using fasteners such as bolts and nuts.

Figure 4 shows a high-load thermal bridge blocking type external insulation with improved adhesion performance by the three-dimensional adhesive plate 110, additional adhesive plate 110a, adhesive 120, insulation connection pin 130, and acupressure tool 140 of the present invention. This shows the results of an experiment on the attachment strength secured by applying a wind load, etc. while the system 100 was attached to the outside of the structure wall 210.

That is, according to FIG. 4, the insulation material 220 joined using the high-load thermal bridge blocking type external insulation system 100 with improved adhesion performance by pressurizing the insulation material at 10,000pa for 10 seconds does not generate a displacement greater than the standard, so that the insulation material 220 has a predetermined value. It can be seen that adhesion strength can be secured.
