Description

{PAIR GLASS WINDOWS AND DOORS}

The present invention relates to a double-layered glass window, and more particularly, to a double-layered glass window manufactured by adding another glass window to an existing glass window.

A window is a window or door that is installed in an opening of a window or an entrance to block the inside of the building from the outside. The window serves as a wall for isolating the interior and the exterior of the building, and at the same time, it is a passage for supplying sunlight and fresh outside air. Recently, various methods have been proposed to improve the performance of the window due to the deterioration of the facility and the change of the environment. In particular, as a method used to improve the performance of existing windows, the method of changing windows as a whole is the most reliable method for improving window performance in terms of the durability of the windows and the completeness of the facilities. However, . Therefore, many construction methods that improve the performance of the window by introducing the window instead of changing the entire window have been introduced.

In particular, Japanese Laid Open Patent Application No. 2013-167112 entitled " Fire and Heat Insulating Panel "(Prior Art 1) proposed a construction method of attaching a single glass using a base member and a cushion tape, Japanese Patent Application Laid-Open No. 2009-024415 entitled " Windowpane structure and its construction method "(Prior art 2) proposed a construction method in which a double-layered glass is attached and fixed using an adhesive member and an L-shaped fixing member. However, the construction methods such as the prior arts 1 and 2 are unsatisfactory in terms of durability and stability in order to support the additional attached double-layered glass, and there is a problem that it is difficult to obtain the desired heat insulation property because no inert gas is injected.

In order to solve such a problem, Korean Patent No. 10-1159188 entitled " Window apparatus and its construction method "(prior art 3) discloses a closed frame for enclosing the entire window to secure a closed space, And a window for gas injection is proposed. However, such a window has a complicated construction method and a problem of an increase in cost. When the external environment of high temperature and high humidity is prolonged for a long time, moisture penetrates into the space inside the closed frame and the initial insulation property is lowered compared with the installation level There is the inconvenience that it is necessary to replenish the already released gas.

As a result, the insulation performance of the existing window is improved more easily by the addition of the additional window, so that it is possible to replace or repair the window quickly and easily at any time after the additional construction, and the need for the window with long durability and the construction method thereof is increasing .

It is an object of the present invention to provide an additional window through a relatively simple and quick construction process while maintaining existing windows, and to provide a double-layered window that has a reduced construction cost for replacement.

It is also an object of the present invention to provide a double-layered glass window which is watertight, ensures airtightness, and has an improved effect of insulating performance and blocking external noise.

As an embodiment, the spacer may be a foam type, and may be a butyl adiabatic spacer in which butyl is applied to both side regions where the first glass and the second glass are in contact.

Further, the spacer may include a desiccant or a desiccant.

In an embodiment, the base frame is formed with protrusions in the longitudinal direction, spacers are attached to the upper portions of the protrusions, and cushioning members may be longitudinally formed on both sides of protrusions in contact with the first glass and the second glass.

As an example, the buffer member may be a polyamide material.

As an example, the modulus of elasticity of the gasket may be 1000 MPa to 3500 MPa.

The gasket further includes a pressing portion contacting the inner surface of the second glass, a supporting portion contacting the fixing clip, a coupling portion inserted between the inner surface of the second glass and the fixing clip, and a coupling portion, And at least one friction wing that contacts the side surface.

Further, the gasket may further include a water film wing which is in contact with the inner surface of the second glass in the longitudinal direction on the upper portion of the pressing portion.
