JP7511042B2 - Window and door installation method using expansion tape - Google Patents

Description

The present invention relates to a window and door installation method using expansion tape.

In homes, as well as apartments and large buildings, there are doors of various shapes and sizes for people or goods to enter and exit, and windows of various shapes for air circulation with the outside, lighting, or visual effects.

Most multi-generational apartment buildings have balconies at the front, rear, or both, which have window frames or sashes to provide protection from the outside world.

Such window frames or sashes include a window frame that is fixed to an opening in a wall that forms a balcony or window of a building, a sash frame, and a door that is movable or can be opened and closed on the sash frame. Meanwhile, after the window frame and sash frame are installed, a gap is often formed between the window frame or sash frame and the bottom of the balcony or veranda.

For this reason, in order to finish or finish such gaps, the gaps are filled with a back-up material such as foam, and then a final finish is given with silicone bond. When a sash is installed on the waterproof rise of a balcony, a urethane sealant is applied to the balcony sash and the waterproof rise, but when a window frame or sash is installed, the urethane sealant used to fill the gaps between the window frame and the retaining wall, and between the sash and the retaining wall, has led to various problems.

In the conventional method, polyurethane, hardener, and solvent must be mixed by hand or machine in a container and then transported to the work site. After applying a primer to the area to be worked on, a foam backup material appropriate for the size is filled in, followed by urethane, and if necessary, masking tape is used to clean the sealing surface.

The conventional urethane application method mentioned above requires the use of a rope to fill the prepared backup material, and polyurethane, hardener and solvent must be mixed in a container. After 2-3 hours, the mixture hardens and cannot be reused. In addition, after application of the urethane, the tools must be taken care of, which is troublesome. In particular, the conventional urethane application method has the problem that when the temperature difference between summer and winter, and between day and night, fluctuates between 40-50°C, the repeated contraction and expansion of the urethane causes cracks to form on the contact surface between the sash and the retaining wall, resulting in water leakage.

In addition, with conventional urethane application methods, after filling the urethane, gas is generated, causing bubbles to form, resulting in user dissatisfaction and the need to redo the work, and if contaminants such as dust get on the urethane, it cannot be cleaned, causing discomfort to users.

The present invention relates to a window and door installation method using an expanding tape.
First, before describing the window installation method using the expansion tape, a window sealing system will be described with reference to Figs. 1 to 4.
FIG. 1 is a schematic diagram of a window sealing system according to a first embodiment of the present invention.
Referring to FIG. 1, the window sealing system includes a window 100 installed in an opening in a wall 200, an expansion tape 110 positioned between the periphery of the window 100 and the opening in the wall 200, an exterior sealant 124 positioned on the exterior side between the periphery of the window 100 and the opening in the wall 200, and an interior sealant 122 positioned on the interior side between the periphery of the window 100 and the opening in the wall 200.

The expansion tape 110 has an adhesive applied to one side for attachment to the periphery of the window 100, and after being attached to the window 100, it expands after a certain period of time to fill the empty space between the window 100 and the wall. The expansion tape 110 described above has been disclosed in detail in prior art such as Korean Patent No. 10-20002603 (Name of invention: Reinforcing member for absorbing vibrations and window with reinforcing member combined) filed by the applicant, so a detailed description of the details will be omitted.

The expansion tape 110 may have a width equal to or narrower than the width of the periphery of the window 100. That is, when the expansion tape 110 is attached to the periphery of the window 100, it is attached so as not to protrude outside the window 100, and spaces may be formed to a predetermined depth from the outside and inside of the room. As a result, a sealant, which will be described later, is inserted into the spaces formed to a predetermined depth from the outside and inside of the room, and the window 100 may be more firmly fixed to the wall 200.

The exterior sealant 124 and the interior sealant 122 are generally used in gaps to provide airtight and watertight properties, and are rubber-like substances or soft or highly viscous liquid rubber compositions that absorb and mitigate expansion and contraction, vibration, and deformation between components. Conventional urethane application methods have had problems with cracks occurring at the contact surface between the sash and the retaining wall surface due to repeated contraction and expansion of the urethane when the temperature difference between summer and winter, and between day and night, fluctuates between 40 and 50 degrees Celsius, resulting in water leakage.

That is, the exterior sealant 124 is located outside the room and prevents foreign objects from entering the space between the window 100 and the wall 200, and the interior sealant 122 is located inside the room and prevents foreign objects from entering the space between the window 100 and the wall 200. In addition, the exterior sealant 124 and the interior sealant 122 also serve to prevent the window 100 from being separated from the wall 200. By way of example, the exterior sealant 124 and the interior sealant 122 may be silicone sealants containing silicone, but are not limited thereto.

FIG. 2 is a schematic diagram of a window sealing system according to a second embodiment of the present invention.
Referring to FIG. 2, the expansion tape 110 may be positioned on both the indoor side and the outdoor side of the periphery of the window 100 .

In detail, when the width of the window 100 is greater than the width of the expansion tape 110, the window sealing system can maximize the effect of the expansion tape 110 by attaching the indoor expansion tape 114 to the indoor side of the periphery of the window 100 and the outdoor expansion tape 112 to the outdoor side. The indoor side of the periphery of the window 100 mentioned above means the area located on the indoor side based on the center of the periphery of the window 100, and the outdoor side of the periphery of the window 100 means the area located on the outdoor side based on the center of the periphery of the window 100.

For example, the expansion tapes 110 may be attached so as to be spaced apart from each other as shown in FIG. 2, but are not limited thereto, and a plurality of expansion tapes 110 may be attached with adjacent surfaces in close contact with each other. To this end, the expansion tape 110 may be divided to have a width of about 40% to 25% of the width of the periphery of the window 100 and used as the exterior expansion tape 114 or the interior expansion tape 112. As a result, a predetermined space may be formed between the exterior expansion tape 112 and the interior expansion tape 114. Through this, the present invention provides a similar effect without adhering the expansion tape to the entire area of the periphery of the window 100, and can reduce the use of the expansion tape 110.

FIG. 3 is a schematic diagram of a window sealing system according to a third embodiment of the present invention.
Referring to FIG. 3, the window sealing system may include an expansion tape 110 disposed on the exterior side of a periphery of a window 100, and a polyurethane foam 130 disposed on the interior side of the periphery of the window 100.

In detail, the present invention can attach the expansion tape 110 to the exterior side of the periphery of the window 100, install the window 100 in the opening of the wall 200, and then inject and harden the polyurethane foam 130 into the space between the window 100 and the wall 200 on the interior side. Then, the polyurethane foam 130 that bulges outward from the window 100 can be removed using a cutter or the like. The polyurethane foam 130 has excellent adhesive strength and heat insulation properties, and not only can it more firmly fix the window 100 to the wall 200, but it can also minimize the transfer of heat from inside the room to the outside. Through this, the present invention can provide a similar effect without adhering the expansion tape 110 to the entire area around the window 100, and can reduce the use of the expansion tape 110.

FIG. 4 is a schematic diagram of a window sealing system according to a fourth embodiment of the present invention.
4, the exterior sealant 124 is a silicone sealant and the interior sealant 122 is a hybrid sealant. In the window sealing system shown in the first embodiment, the exterior sealant 124 may be a silicone sealant and the interior sealant 122 may be a hybrid sealant, and in the window sealing systems according to the second and third embodiments, the exterior sealant 124 may be a silicone sealant and the interior sealant 122 may be a hybrid sealant.

The hybrid sealant is an eco-friendly sealant that combines the advantages of silicone and urethane, and is known to have excellent weather resistance, adhesive strength, and elasticity, and can be used with paint after curing. It is characterized by an elongation rate of 400% and a hardness of 35 to 45.

FIG. 5 is a flow chart showing a method for installing a window using the expansion tape 110 according to an embodiment of the present invention.
Hereinafter, a method for installing a window using an expansion tape 110 according to an embodiment of the present invention will be described with reference to FIG.
In step S110, the adhesive-coated portion of the expansion tape 110 is attached to the periphery of the window 100.

The expansion tape 110 may have a width approximately equal to the width of the periphery of the window door 100. In another embodiment, if the expansion tape 110 is narrower than the width of the periphery of the window door 100, the indoor expansion tape 114 may be attached to the indoor side of the periphery of the window door 100, and the outdoor expansion tape 112 may be attached to the outdoor side. In yet another embodiment, the expansion tape 110 may be attached only to the outdoor side of the periphery of the window door 100.

In step S120, the window 100 is fixed to the opening of the wall body 200. At this time, the window 100 may be fixed using a separate fixing device (such as a fastener), but is not limited thereto.
In step S130, the expansion tape 110 expands to seal the space between the window 100 and the wall 200.

In addition, in an embodiment in which the expansion tape 110 is attached only to the exterior side of the periphery of the window 100, the method may further include a step of injecting polyurethane foam 130 onto the interior side of the periphery of the window 100 after step S130.
In step S140, the outdoor side and the indoor side of the sealed space are sealed with a sealant.

The exterior sealant 124 and the interior sealant 122 may use the same silicone sealant, but are not limited thereto; the exterior sealant 124 may use a silicone sealant and the interior sealant 122 may use a hybrid sealant.

The above description of the present invention is for illustrative purposes only, and a person having ordinary skill in the art to which the present invention pertains will understand that the present invention can be easily modified into other specific forms without changing the technical concept or essential features of the present invention. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and are not limiting.
