Description

Watertight Curtain Wall Frame {WATERTIGHT FRAME FOR CURTAIN WALL STRUCTURE}

The present invention relates to a curtain wall frame that can prevent rainwater from entering the room through a frame in a curtain wall structure of a building, and more specifically, it is excellent in the inside of a coupling portion of a frame in which an exterior panel such as double glass is fixed. It relates to the structure of a water-tight curtain wall frame that can fundamentally prevent the penetration.

A curtain wall is a non-bearing wall that constitutes the outer periphery of a building, and is a structure that is attached to the frame of a building by means of a fastener. The curtain wall can be used for high-rise buildings because it can make the outer wall lighter, mass-produce it in a factory by standardization, and can construct it in parallel with the framing work. The curtain wall is divided into mullion type, spandrel type, and grid type depending on the appearance type. Especially, the grid type can exhibit vertical and horizontal lattice-like appearance. It is often used for curtain walls.

On the other hand, the curtain wall should provide a comfortable indoor environment by protecting the interior of the building from wind and rain. However, the curtain wall is not a structural member that forms the building itself, such as a frame, so it is often insufficient to absorb the displacement of the building due to lack of rigidity. Due to this, in particular, the airtightness is not maintained at the part where the horizontal frame and the vertical frame cross, and rainwater enters the room, causing discomfort to the room, whitening, and also deteriorating the durability of the curtain wall. In addition, even if there is a defect in the coupling portion inside the frame, it is not easy to check with the naked eye, and work for maintenance is not easy.

For example, FIG. 1 is disclosed through Korean Patent Publication No. 10-1652844, and shows a structure in which rainwater does not penetrate into the interior by riding inside the frame by installing a watertight member at a coupling portion between a vertical frame and a horizontal frame.

As shown in FIG. 1, the curtain wall having the watertight structure of the registered patent publication No. 10-1652844 crosses the horizontal bar 10 and the vertical bar 20 to form a square frame 1, and the horizontal bar (10) and the vertical bar (20 each of which is provided with a heat insulating bar 40 of a tubular portion having a rectangular cross-section, the inside of the heat insulating bar 40 is provided with a nut portion 60 is provided with a tubular portion (62) Washer bar 90 is fixed to the double glass window (2), the horizontal bar 10 and the vertical bar via the bolt (63) fastened to the nut portion 60 passed through the tubular portion (62) ( 20), and the washer bar 90 is closed by a cover bar 96.

At this time, a rubber packing 92 is installed between the outer surface of the double glass window 2 and the washer bar 90, and water is prevented from flowing into the heat insulation bar 40 through the interior edge gap of the glass window 2 The backup rod sponge 70 is penetrated through the tubular portion 62 along the indoor side of the double glass window 2 and is arranged to be in surface contact with the inner side of the double glass window 2. In addition, a weatherproof sealant 80 is filled around the tubular portion 62 adjacent to the double glass window 2 to prevent water from entering the interior side through the outdoor edge slit of the double glass window 2.

However, the water-tight structure of the above-described registered patent publication No. 10-1652844 is difficult to maintain because it is necessary to separate the washer bar 90 from the horizontal bar 10, etc. in order to replace the aged rubber packing 92. If a defect occurs in the backup rod sponge 70 and the sealing material 80 inside and outside the tubular portion 62 of the 60), the above defects can be easily checked with the naked eye unless the washer bar 90 and the nut portion 60 are disassembled. There is a problem that can not be, and furthermore, it is not considered at all with respect to the penetration of each washer bar 90 in the vertical and horizontal direction through the cross-joined portion.

In addition, FIG. 4 is a cross-sectional view in the A-A portion of FIG. 2, and FIG. 5 is a cross-sectional view in the B-B portion of FIG. 2.

The curtain wall structure to which the watertight type curtain wall frame of the present invention is applied is combined such that the vertical frame 100A and the horizontal frame 100B (collectively referred to as'frames') have a lattice shape as shown in FIG. 2. In the meantime, it is applied when an exterior panel 140 such as double glass is installed therebetween.

The watertight curtain wall frame of the present invention is composed of a main body frame (110A, 110B) located inside the exterior panel 140 inside and a faucet frame (120A, 120B) located outside the exterior panel 140. .

More specifically, the vertical frame (100A) is made up of the vertical body frame (110A) and vertical tap frame (120A) on the indoor side with the exterior panel (140) therebetween, and the horizontal frame (100B) also includes the exterior panel (140). It is composed of a horizontal body frame 110B and a horizontal faucet frame 120B on the indoor side, and the vertical body frame 110A and the horizontal body frame 110B (collectively referred to as'body frames') are orthogonal to each other. While being combined, the vertical tap frame 120A and the horizontal tap frame 120B (collectively referred to as a'tap frame') are combined while being orthogonal to each other.

In addition, the faucet frame (120A, 120B) is a support piece 121 and the support piece coupled to the body frame (110A, 110B) so as to fix the exterior panel 140 together with the body frame (110A, 110B) It consists of a cover piece (122) that induces the flow of rain water while protecting the coupling structure and appearance of (121). That is, on both sides of the cover piece 122, there is formed a rainwater induction groove 125 provided with a projection jaw 125a, so that the rainwater on the surface of the exterior panel 140 covers the cover piece 122 of the horizontal tap frame 120B. It flows along the rainwater induction groove 125 provided in the rainwater induction groove 125 provided in the cover piece 122 of the vertical tap frame 120A to be discharged to the outside.
