Description

FACADE-SPLIT WINDOW HAVING OPTIMIZED WATERTIGHT STRUCTURE

The present invention relates to a facade-split window. More particularly, the present invention relates to a facade-split window having an optimized watertight structure that enables to increase assembly strength and water inflow prevention performance of a transom horizontally partitioning an opening of a window frame and includes a drainage structure facilitating natural drainage from a lower part of the window frame.

Recently, buildings such as apartment buildings and residential complexes have become increasingly taller, whereby windows installed in buildings are affected by ever greater external wind pressure. Accordingly, in high-rise buildings, a window having sufficient strength to withstand external wind pressure and superior watertightness should be installed.

With regard to windows installed in high-rise buildings, a facade-split structure constituted of transoms and mullions is applied to impart structural stability.

KR 10-2014-0054571A (published on May 09, 2014), which relates to a window having such a facade-split structure, has been published.

In particular, as illustrated in FIG. 1, a facade-split window 1 includes a transom 3. Parts to which the transom 3 and a window frame 2 are coupled require high watertightness.

In this case, the parts to which the transom 3 and the window frame 2 are coupled are usually welded. However, in this case, a water inflow prevention performance cannot be sufficiently secured, whereby problems related to watertightness may occur.

To prevent this, a structure wherein the window frame 2 is coupled to both ends of the transom 3 by a "ㅛ"-shaped assembly bracket 4 to firmly assemble the transom 3 has been proposed.

However, the structure of the assembly bracket 4 is simple and, in particular, the assembly bracket 4 is biased to a portion of the transom 3 due to structural characteristics of a window frame, whereby assembly strength thereof is decreased.

Meanwhile, in the case of coastal windows, a storm, rainwater, or seawater scattered by strong waves often enters into the window frame 2, thereby requiring watertightness.

To increase such watertightness, the window frame 2 has been provided with drain holes. These drain holes are usually formed by horizontally opening a lower part of the window frame 2.

However, the window frame 2 having such structure may discharge water to the outside through the drain holes when the amount of water introduced to the outside is small, but, when a certain amount or more of water is introduced at once, it is difficult to cope with the same due to the limited drainage capacity of the drain holes. Accordingly, water not discharged to an outdoor side may be introduced into a room through gaps between indoor rails.

Therefore, the present invention has been made in view of the above problems, and it is one object of the present invention to provide a facade-split window having an optimized watertight structure that enables to increase assembly strength and water inflow prevention performance of a transom horizontally partitioning an opening of a window frame and includes a drainage structure facilitating natural drainage from a lower part of the window frame.

In accordance with one aspect of the present invention, provided is a facade-split window including a window frame; a transom coupled to an inner facing surface of the window frame by an assembly bracket to partition an outdoor opening of the window frame into an upper opening and a lower opening; at least a pair of indoor windows slidably and openably coupled to an indoor opening of the window frame; and outdoor windows respectively coupled to the upper opening and the lower opening.

As apparent from the fore-going, a transom horizontally partitioning an outdoor opening of a window frame according to the present invention is coupled by a high-strength integrated assembly bracket, thereby providing increased assembly strength.

In addition, when a water inflow prevention wall providing a water collection space is formed on an upper surface of the transom, an indoor wall is formed higher than an outdoor wall, thereby preventing water contained in a water collection space from overflowing to an indoor side. Accordingly, water inflow prevention performance of the window frame may be improved.

Further, a stepwise drainage structure is applied to a lower part of the window frame, thereby facilitating natural drainage.

Hereinafter, the functions or constructions of preferred embodiments of the present invention are now described more fully with reference to the accompanying drawings.

Here, when reference numerals are applied to constituents illustrated in each drawing, it should be noted that like reference numerals indicate like elements throughout the specification.

FIG. 2 illustrates an elevation view of an indoor side of a facade-split window to which an optimized watertight structure according to the present invention is applied; FIG. 3 illustrates a sectional view taken along line I-I of FIG. 2; FIG. 4 illustrates a side sectional view of a window frame according to the present invention; and FIG. 5 illustrates a side sectional view of a transom according to the present invention.

Referring to FIGS. 2 and 3, a facade-split window to which an optimized watertight structure according to a preferred embodiment of the present invention is applied includes a window frame 100; a transom 110 coupled to an inner facing surface of the window frame 100 by an assembly bracket 120 to partition an outdoor opening of the window frame 100 into an upper opening S1 and a lower opening S2; at least a pair of indoor windows 210 slidably and openably coupled to an indoor opening of the window frame 100; and outdoor windows 220 respectively coupled to the upper opening S1 and the lower opening S2.

Such a configuration of the present invention is described in detail as follows.

First, the window frame 100 has a stepwise drainage structure wherein a lower inner peripheral surface of the window frame 100 is inclined downward to the outdoor side and an outdoor side of the window frame 100 is formed lower than an indoor side thereof.

In other words, as illustrated in FIG. 4, since the window frame 100 has a stepwise drainage structure, introduction of water, which has been introduced into the window frame 100 from the outside, into an indoor side may be prevented. Introduced water is naturally discharged to the outside through a plurality of drain holes (not shown) penetrating indoor rails 101 and outdoor rails 103.

In addition, a cover profile 130 may be coupled to a water collection space between the indoor rails 101 and the outdoor rails 103 of the window frame 100 so as to conceal water pooling due to drainage delay.

In this case, the cover profile 130 may be formed in a "ㄷ"-shape wherein a lower part thereof is open, and may have a plurality of drain holes (not shown) at a lower part thereof such that water in the water collection space is discharged to the outside.

In addition, the cover profile 130 is provided with engaging protrusions 131 such that both sides of the cover profile 130 are fitted and fixed to the water collection space in a snap-fit manner, thereby preventing unintentional detachment of the cover profile 130.

Referring to FIG. 3 again, the outdoor windows 220 is constituted of at least a pair of first windows 221 slidably and openably coupled to the upper opening S1; and a second window 223 coupled and fixed to the lower opening S2. Of course, the present invention is not limited to such a configuration, and sliding windows and a fixed window can be arbitrarily changed according to user preference.

Referring to FIG. 5, the rails 111, which is configured such that the first windows 221 are slidably and openably coupled thereto, and a water inflow prevention wall 113, which is spaced from the outside and inside by the rails 111 and provides the water collection space between the outside and inside, are provided on an upper surface of the transom 110.

By the water inflow prevention wall 113, the indoor wall 113a is formed to be higher than the outdoor wall 113b. That is, water inflow prevention ability of the transom 110 may be improved by increasing the heights of the rails 111 and the water inflow prevention wall 113, compared to conventional cases, thereby preventing water contained in the water collection space from overflowing to an indoor side. In particular, the height (h) of the indoor wall 113a is 38 to 42mm, preferably 40mm, from an upper surface of the transom 110 (usually 35mm in conventional cases).

Referring to FIGS. 6 to 8, the transom 110 having the aforementioned structure is coupled and fixed to the window frame 100 by the assembly bracket 120. Such an assembly bracket 120 may be made of a metallic material.

In particular, the assembly bracket 120 is constituted of a first fixing part 121 fixed to an inner peripheral surface of the window frame 100 by fastening members; and a second fixing part 123 protruded, in a horizontal direction, from one surface of the first fixing part 121, and fitted onto upper and lower surfaces of an end of the transom 110 by fastening members.

In this case, the first fixing part 121 is provided with first coupling grooves 121a such that protrusions 105 included in the window frame 100 are seated on the first coupling grooves 121a (see FIG. 7). That is, the first coupling grooves 121a enable the assembly bracket 120 to be easily installed at a facing surface of the window frame 100 including the protrusions 105, thereby accomplishing firm engagement of the assembly bracket 120 compared to conventional cases. Accordingly, assembly strength of the transom 110 may be increased.

The second fixing part 123 is provided with second coupling grooves 123a to be fitted to the rails 111, which are provided on upper surface of the transom 110, and structures, which are provided on a lower surface of the transom 110, as in the first fixing part 121 (see FIG. 8). Accordingly, firm engagement of the second fixing part 123 may be accomplished.

In the facade-split window to which the optimized watertight structure according to the present invention is applied, the transom 110 horizontally partitioning an outdoor opening of the window frame 100 is coupled by the high-strength integrated assembly bracket 120, thereby providing increased assembly strength.

In addition, when the water inflow prevention wall 113 providing a water collection space is formed on an upper surface of the transom 110, the indoor wall 113a is formed higher than the outdoor wall 113b, thereby preventing water contained in a water collection space from overflowing to an indoor side. Accordingly, water inflow prevention performance of the window frame may be improved.

Further, the stepwise drainage structure is applied to a lower part of the window frame 100, thereby facilitating natural drainage.

While the present invention has been described referring to the preferred embodiments, those skilled in the art will appreciate that many modifications and changes can be made to the present invention without departing from the spirit and essential characteristics of the present invention.
