Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unitized curtain wall isobaric structure capable of preventing water from entering and ensuring high water tightness.

[0002]

2. Description of the Related Art A unitize curtain wall is a factory that assembles all materials, including glass, fireproof boards, and brackets, and brings them into the field in a unitized state.
It is a method of directly attaching to the front fastener, and is a dry method in which the upper and lower sides and left and right sides of each unit are fitted by continuous fitting method, there is no wet seal on the curtain wall surface, and the unit is composed of bracket and fastener It is connected with the adjacent upper, lower, left and right units with a joint connecting material, which has a high rate of factory production, high quality, and requires only a short construction period.
In addition, it has many features such as construction in rainy weather.

At the joints of the unit upper frame, the unit lower frame, the unit right vertical frame and the unit left vertical frame of the upper, lower, left and right units of such a unitized curtain wall, the upper and lower unit upper frames and the lower unit frame are jointed. To
At least two inner / outer flanges provided on the upper frame side of the unit so as to project upward, and two inner / outer flanges provided on the lower frame side of the unit so as to project downward are fitted to each other. The right and left unit vertical frames of the left and right units are connected to each other by means of at least two inner and outer flanges provided on the right vertical frame side of the unit and the left vertical frame side of the unit. The inner and outer two flanges provided on the side of are joined together by fitting. Further, the joint portion is connected by a joint connecting material in order to maintain the level of the left and right units. It should be noted that various variations can be configured by attaching partition glass, panels, etc., in the vertical direction of the unit without making any visible difference.

[0004]

In the above-mentioned conventional unitized curtain wall, as a water-stop structure when weather and rain are received, the notch of the unit lower frame is provided outside the unit upper frame at each flange fitting portion. In addition to providing a draining flange that fits to the inside of the unit, a draining packing is installed on the flange fitting part on the outside of the two inner and outer flanges, and an air leak prevention packing is installed on the flange fitting part on the indoor side. Has a drain hole in the center flange. However, according to the above water-stopping structure, it is possible to maintain watertightness (about 75 Kgf / m ² ) to some extent, but it is impossible to secure higher watertightness.

[0005]

In order to solve the above-mentioned problems, the isobaric structure of the unitized curtain wall according to the present invention assembles all materials including glass, refractory board and bracket into a unit, With the method of attaching directly to the attached fastener, the upper frame of each unit,
The joints of the unit lower frame, the unit right vertical frame, and the unit left vertical frame are joined together by fitting at least two inner and outer flanges to each other, and the outer side flange fitting part has a draining packing and an indoor side In a unitized curtain wall in which a leakage prevention packing is installed in the flange fitting part, a space between the flanges partitioned by the water drain packing and the leakage prevention packing in the fitting part of the unit upper frame and the unit lower frame. The outside air is introduced into the space, and the outside space is provided with an outside air introduction notch for communicating the space and the space of the fitting portion of the unit right vertical frame and the unit left vertical frame to make the pressure in these spaces equal to the outside air. It is a feature.

[0006]

Since the unitized curtain wall isobaric structure according to the present invention is configured as described above, the unit upper frame and the unit lower frame are separated from each other by the water drain packing and the leakage prevention packing of the fitting portion. The outside air is introduced into the space between the flanges through the outside air introduction notch, and the outside air is introduced into the space of the fitting part of the unit right vertical frame and the unit left vertical frame that communicate with the space, thereby Can be made to have the same pressure as the outside air, which can prevent water from entering these spaces.
