Description

Insulating sheet for heterogeneous material wall joints and construction method of wallpaper using the same}

In the present invention, when walls of different materials are joined to form a single wall surface and wallpaper is applied by envelope application, the heterogeneous behavior of the wall is not transmitted to the wallpaper due to the insulating sheet provided between the wall and the wallpaper. This is about an insulating sheet for dissimilar wall joints that can prevent wallpapering and finishing defects.

In multi-unit housing such as apartments, the walls within each unit are constructed with reinforced concrete walls or dry walls, and after wall construction, wallpaper is applied to the interior walls as a final interior finish.

In general, wallpaper is attached to the entire wall using an all-over or envelope application method.

Ontongbaprum is a method of attaching by applying glue to the entire back surface of the wallpaper. Because the shape of the wall surface is exposed as is on the entire surface of the wallpaper, there is a problem of spoiling the aesthetics if the wall surface condition is uneven or the level of smoothness is not constant.

Envelope application is a method of applying glue only to the back edge of the wallpaper. Envelope application means that the center of the wallpaper is not attached to the wall but floats. As the wallpaper dries, it shrinks and is pulled taut, minimizing twists or openings in the wallpaper. In addition, it is widely used because it maintains its own smoothness regardless of the smoothness of the wall surface and is easy to remove when replacing wallpaper.

On the other hand, there are times when walls of different materials meet to form a single wall surface, such as when a dry wall such as gypsum board and a wet reinforced concrete wall meet to form a single wall surface.

In this case, because the coefficient of thermal expansion is different between heterogeneous materials, the degree of expansion or contraction of the wall depending on temperature changes is different. And due to differences in stiffness between heterogeneous walls, differences in strain rates are inevitable even when the same load is applied.

In this way, when the behavior of dissimilar walls is different, defects may occur in the wall joints, such as the wall joints being spaced apart or misaligned.

In particular, defects such as twisting or tearing of the wallpaper near the wall joints frequently occur on the finished surface where the wallpaper is applied to the front of a heterogeneous wall.

Hereinafter, the present invention will be described in detail according to the accompanying drawings and preferred embodiments.

Figure 1 is a cross-sectional view showing a state in which dissimilar walls are joined. And Figure 2 is a perspective view showing the insulating sheet for dissimilar wall joints of the present invention, Figure 3 is an elevation view showing the insulating sheet in an installed state, and Figure 4 is an elevation view showing the wallpapered state.

As shown in Figures 2 to 4, etc., the insulating sheet for dissimilar wall joints of the present invention is used to construct wallpaper (2) on the entire wall where the first wall (1a) and the second wall (1b), which are mutually dissimilar materials, are joined. It is attached to the lower and upper front surfaces of the joint between the first wall (1a) and the second wall (1b) so as to cross the first wall (1a) and the second wall (1b), respectively, to the front of the wall. It is characterized by comprising an adhesive layer 31 attached and an insulating film layer 32 provided on the entire surface of the adhesive layer 31.

The present invention relates to the problem of plastering paper (2), such as twisting or tearing, at the joints of dissimilar walls when wallpapering paper (2) is applied to the entire surface of a wall where walls of different materials are joined to form one wall surface. The purpose is to provide an insulating sheet for dissimilar wall joints that can prevent finishing defects.

The present invention is to construct wallpaper (2) on the front of the joint when the first wall (1a) and the second wall (1b) made of different materials meet in the horizontal direction as shown in FIG. 1 and a vertical joint occurs at the joint. It is used for.

In particular, this is to prevent wallpapering defects at the joints of dissimilar walls when finishing the wallpapering by applying the wallpapering paste only to the edge of the wallpapering paper (2).

1 and other examples show an embodiment in which the first wall 1a is a reinforced concrete wall and the second wall 1b is a dry wall, but the embodiment is not limited to this type of wall.

The insulating sheets 3 are provided as an upper and lower pair and are attached to the upper and lower front surfaces of the dissimilar wall joint, respectively.

That is, the insulating sheet 3 is a wall in which the first wall 1a and the second wall 1b are joined in the horizontal direction so that the front surface is on the same surface, and the insulating sheet 3 is formed at the joint of the first wall 1a and the second wall 1b. It is attached to the front of the joint between the first wall (1a) and the second wall (1b) so as to cross horizontally.

The insulating sheet 3 includes an adhesive layer 31 attached to the front of the wall and an insulating film layer 32 provided on the front of the adhesive layer 31, and may be formed in a rectangular shape with a long horizontal side. there is.

The wallpaper (2) applied to the front of the wall is attached to the front of the insulating sheet (3) at the joint of the dissimilar walls.

At this time, the upper and lower width of the insulating sheet 3 can be made larger than the width of the wallpapering paste 20, etc., applied to the back of the wallpapering paper 2 in order to attach the wallpapering paper 2 to the wall by wrapping it (Figure 4) ). In Figure 4, hatched lines indicate the application position of the wallpaper paste (20).

The insulating sheet (3) is provided between the wall and the wallpaper (2) to prevent the heterogeneous behavior of the first wall (1a) and the second wall (1b) from being transmitted to the wallpaper (2).

That is, the wallpaper 2 is not attached directly to the front of the wall at the joint of the dissimilar walls, but is attached to the front of the insulating sheet 3 across the joint of the dissimilar walls. Therefore, even if the first wall (1a) and the second wall (1b) behave differently due to expansion or expansion, the wallpaper (2) is not affected by this, preventing defects such as twisting or tearing of the wallpaper (2). can do.

The size of the left and right widths of the insulating sheet 3 can be determined according to the strain rate and width of the wall to be joined.

The left and right widths of the insulating sheet (3) are set so that the insulating sheet (3) sufficiently offsets the heterogeneous behavior of the two walls at the junction of the first wall (1a) and the second wall (1b) and does not affect the wallpaper (2). It is desirable to have at least 300 mm or more.

The insulating film layer 32 may be formed of a hard material.

The insulating film layer 32 blocks heterogeneous behavior caused by individual expansion or contraction of the first wall 1a and the second wall 1b between the wall and the wallpaper 2, and transfers the deformation of the joint to the wallpaper 2. Make sure it doesn't happen.

Therefore, even if the heterogeneous wall is deformed at the joint between the first wall 1a and the second wall 1b, the insulating sheet 3 must not be deformed or the deformation must be minimized.

Accordingly, the insulating film layer 32 of the insulating sheet 3 can be formed of a hard material.

For example, the insulating film layer 32 may be formed of a hard synthetic resin sheet such as PET or PP, or a thin metal plate such as a tin plate.

In this way, if the insulating film layer 32 is formed of a hard material sheet, it is possible to block the transfer of motion to the base surface of the wall.

The insulating film layer 32 may have a thickness of 100 to 800 μm.

In order for the insulating sheet 3 to effectively block the heterogeneous behavior of the first wall 1a and the second wall 1b, the thickness of the insulating film layer 32 is preferably 100 μm or more.

If the thickness of the insulating film layer 32 is less than 100㎛, deformation occurs in the insulating film layer 32 during heterogeneous behavior of the first wall 1a and the second wall 1b, and the wall deformation occurs in the wallpaper 2. is delivered to

The thicker the insulating film layer 32 is, the more advantageous it is for blocking heterogeneous behavior of the wall.

However, if the thickness of the insulating film layer 32 exceeds 800㎛, the thickness of the insulating sheet 3 becomes excessively thick and a step occurs in the wallpaper 2, which may spoil the aesthetics.

As shown in FIG. 2, a wallpaper attachment layer 33 may be further provided on the front surface of the insulating film layer 32.

When the insulating film layer 32 is formed of a hard material such as PET, the adhesive strength between the insulating film layer 32 and the wallpapering paste 20 is not sufficient, so the wallpapering paper 2 is attached using the wallpapering paste 20. This can be difficult to do.

In this case, wallpapering bond (binder) must be applied to the front of the insulating sheet (3) and then painting paper (2) must be installed.

However, wallpapering bond has a tendency to bleed off when applied to walls and has poor workability. In addition, since the wallpaper paste 20 is applied to the area where the wallpaper paper 2 is attached to the wall, there is the inconvenience of having to separate the wallpaper paste 20 application section and the wallpaper bond application section and apply it twice.

Therefore, when manufacturing the insulating sheet 3, the wallpapering adhesive layer 33 is manufactured to be integrally laminated on the entire surface of the insulating film layer 32, so that the wallpapering paste 20 can be simply applied without a separate process of applying a wallpapering bond. The wallpaper (2) can be configured to be installed in batches.

The wallpaper adhesion layer 33 may be made of non-woven fabric, paper, etc., which has excellent adhesion to the wallpaper paste 20.

Figure 5 is a perspective view showing another embodiment of the insulating sheet for dissimilar wall joints of the present invention.

The adhesive layer 31 may be composed of a self-adhesive elastic sheet.

The adhesive layer 31 can be formed on site by applying an adhesive to the back of the insulating film layer 32.

Alternatively, the adhesive layer 31 may be made of a self-adhesive sheet and manufactured integrally with the insulating film layer 32 on the back of the insulating film layer 32 in order to ensure adhesive quality and minimize field work.

Accordingly, release paper 310 can be pre-attached to the back of the adhesive layer 31 (FIG. 5), and after removing the release paper 310 immediately before construction of the insulation sheet 3 in the field, the insulation sheet 3 is placed on the front of the wall. can be attached.

Meanwhile, the present invention is intended to block the heterogeneous behavior of the first wall (1a) and the second wall (1b) by forming the insulating film layer 32 with a hard material. To achieve this, the heterogeneous behavior of the walls in the adhesive layer 31 is required. must be able to absorb.

Therefore, the adhesive layer 31 is made of an elastic sheet, so that even if deformation occurs at the wall joint, the adhesive layer 31 absorbs the deformation and prevents stress from being transmitted to the insulating film layer 32.

For this purpose, the adhesive layer 31 can be formed of an adhesive made of an elastic material with similar elongation and adhesion strength.

The adhesive layer 31 may be made of any one of acrylic, silicone, urethane, hot melt, butyl rubber compound, and asphalt compound, and is particularly preferably made of hot melt, which has excellent elasticity and adhesion.

The method of painting and painting using the insulating sheet of the present invention relates to a method of constructing painting using the insulating sheet for dissimilar wall joints of the present invention described above with reference to FIGS. 2 to 5.

In the wallpaper construction method using the insulating sheet of the present invention, first (a) the first wall (1a) and the second wall (1b) are horizontally placed at the lower and upper front surfaces of the joint between the first wall (1a) and the second wall (1b). Attach the insulating sheets 3 so as to cross each other (Figure 3).

In step (a), the surface of the wall is cleaned by removing foreign substances, and then a pair of long rectangular insulating sheets (3) are prepared. Then, the insulating sheet 3 is attached to the upper and lower surfaces of the front surface of the joint between the first wall 1a and the second wall 1b, respectively, using the adhesive layer 31 of the insulating sheet 3.

When the baseboard (10) is constructed at the bottom of the wall, the lower insulating sheet (3) is installed in close contact with the top of the baseboard (10).

And (b) putty (4) is applied to the front of the first wall (1a) and the second wall (1b) at both ends of the insulating sheet (3) to prevent steps at the ends of the insulating sheet (3) (Figure 6).

As the insulating sheet 3 is attached in step (a), a step is formed on the entire surface of the wall equal to the thickness of the insulating sheet 3. Therefore, putty (4) is installed on the end of the insulating sheet (3) to prevent such steps from occurring.

The putty (4) can be applied to the end side of the insulating sheet (3) as thick as the insulating sheet (3) and thinner toward the other side to prevent a step from forming on the front of the wall.

The putty (4) can be installed on both left and right ends of the insulating sheet (3), that is, on two sides.

In some cases, the putty 4 may be applied to three sides of each insulating sheet 3, including the upper side of the lower insulating sheet 3 and the lower side of the upper insulating sheet 3.

Finally, (c) attach the wallpaper (2) to the front surface of the first wall (1a), the second wall (1b), and the insulating sheet (3).

In step (c), the wallpaper paste (20) is applied to the back edge of the wallpaper paper (2), and then the wallpaper paper (2) is installed on the entire wall to which the insulating sheet (3) is attached.

Figure 7 is an elevation view showing the state in which the fixing pin is installed.

In step (a), the adhesive layer 31 is formed by applying an adhesive to the back of the insulating film layer 32, and the insulating sheet 3 is attached to the first wall 1a and the second wall 1b. After attachment, the insulating sheet 3 can be fixed to at least one of the first wall 1a and the second wall 1b using a plurality of fixing pins 5 (FIG. 7).

In step (a), adhesive is applied to the back of the insulating film layer 32 immediately before attaching the insulating sheet 3 to form an adhesive layer 31, and then the insulating sheet 3 can be attached to the front of the wall. .

The adhesive may be an acrylic sealant for wallpapering.

The adhesive layer 31 can be formed by evenly applying adhesive to the rear edge and interior of the insulating film layer 32 and then spreading it with a spatula or the like.

At this time, fixing pins (5) can be installed to firmly fix the insulating sheet (3) to the base surface of the wall.

The fixing pin 5 may be a tacker pin or the like.

In particular, in the case of drywall where the adhesion to the acrylic sealant for wallpapering may be reduced, fixing pins (5) are installed to prevent the insulating sheet (3) from falling off to ensure that it is firmly fixed.

In step (a), the adhesive layer 31 is a self-adhesive elastic sheet with release paper 310 attached to the back, and after removing the release paper 310, the insulating sheet 3 is attached to the first wall 1a and the second wall 1a. It can be attached to the wall (1b).

When the adhesive layer 31 is formed of a self-adhesive elastic sheet, the adhesive application process can be omitted in the field, allowing rapid construction.

In addition, when applying the adhesive on site, the adhesion quality may deteriorate depending on the worker's skill level, but if the adhesive layer 31 is made of a self-adhesive elastic sheet, uniform quality can be ensured.

In this case, the insulating sheet 3 is attached immediately after removing the release paper 310.

A coating adhesive layer 33 is further provided on the front surface of the insulating film layer 32, and in step (c), coating paste 20 is applied to the entire surface of the coating adhesive layer 33 of the insulating film layer 32. After this, the wallpaper (2) can be attached.

When the wallpaper adhesive layer 33 is provided on the front of the insulating film layer 32 composed of a hard material, the wallpaper paste 20 is applied all at once on the back edge of the wallpaper paper 2 without the process of constructing a separate wallpaper bond. Wallpaper (2) can be installed.
