Description

Detailed Description of the Invention This invention provides an outdoor rain barrier on the outer periphery of a wall frame assembled in the shape of a frame from upper rock materials, lower horizontal materials, left and right vertical materials, and plate materials made of glass, synthetic resin, metal, etc. A wind barrier is provided on the indoor side, and the space formed by the rain barrier and wind barrier that are in close contact between the adjacent wall frames is provided with the wall frames arranged in parallel in the vertical and horizontal directions and fixed to the frame. This relates to a wall structure of a building in which an opening opened in the lower horizontal member allows the outside to pass through to reduce the pressure difference with the outside air, and allows rainwater to drain out by natural flow.

As is well known, as a type of exterior wall construction method for high-rise buildings, a frame-shaped wall frame with a glass plate attached inside is arranged vertically and horizontally by assembling the upper and lower horizontal members and the left and right vertical members. There is a way to fix it to the frame.

However, with this method, it is necessary to fully consider the rainwater at the interval between adjacent wall frames, and it is necessary to prevent rainwater from seeping into the room from the connection between each horizontal member and vertical member or from the glass bead. We must make sure that we do not let this happen. For this reason,
In order to prevent rainwater from entering, the structure of the rain closure is complicated by double sealing the joints using Sea J-con, polysulfide sealant, etc., and installing a water catcher for draining rainwater, making the construction complicated and requiring a long construction period. It may become longer or the sealing material may deteriorate over time, resulting in poor rain protection.

The present invention has been proposed in view of the above, and to explain the embodiment shown below, the outer wall of the building is constructed by assembling the upper material 1, the lower horizontal member 2, and the left and right vertical members 3, 3 with screws etc. Frame-shaped wall frames a equipped with these are arranged in parallel in the vertical and horizontal directions, and each wall frame a is fixed to the frame.

The upper yokomura 1 has a hollow part 5 for a glass pocket on the outdoor side and a hollow part 6 for draining rainwater on the indoor side, and a rain made of synthetic resin, synthetic rubber, etc. is provided on the outer side of the upper surface part 7 of the hollow part 6. A barrier fastening part 8 and a wind barrier fastening part 9 made of the same material as above are formed in the length direction at the edge of the room.

Further, a connecting row 0 for draining rainwater is provided in the upper surface part 7 so as to be located between the fastening parts 8 and 9. On the other hand, the lower cross member 2 has a hollow part 11 for a glass pocket on the outdoor side and a hollow part 12 for air intake on the indoor side, but the estimated size of the hollow part 12 is shorter than the estimated size of the hollow part 6. Therefore, a plane part 13 is extended from the upper surface of the air intake hollow part 12 toward the indoor side, and the estimated dimensions of the upper cross member 1 and the lower equipment 2 are made equal.

A rain barrier fastening part 8 and a wind barrier fastening part 9 similar to those described above are installed on the lower surface of the hollow part 12 for air intake and the lower face of the flat part 13, respectively. The bottom surface has a closing part 14 located on the outdoor side of the fastening part 8 and a fastening part 8.
The connecting row 5 located on the indoor side of the connecting row 5 is opened by changing its position in the length direction. Furthermore, each vertical member 3 on the left and right is also attached to each of the above equipment 1 and 2.
The same machine has a hollow part 16 for a glass pocket on the outdoor side and a reinforcing hollow part 17 on the indoor side, and a rain barrier fastening part 8 and a wind barrier fastening part 3 9 are provided on the outer surface of the hollow part 17. .

In order to assemble the frame-shaped wall frame a using the above-mentioned upper horizontal member 1, lower member 2, and left and right vertical members 3, 3, remove a portion of the upper and lower ends of the vertical member 3, and Attach the tip of the material 1 or the tip of the lower horizontal material 2 to each other and secure with screws 4, and insert the green end of the glass plate 4 into each glass pocket hollow part 5, 11, 16, and attach the front and rear surfaces. is sealed with beads 18, 18.

Further, a drain hole 19 is formed at the upper end of each vertical member 3 so as to be located on the outdoor side of the fastening part 8. The wall frame a assembled as described above has fastening parts 8 and 9 that are continuous to the outer surfaces of the upper horizontal member, the lower member, and the left and right vertical members. 20 is wound in an endless manner and attached to the fastening part 9 on the indoor side.
A wind barrier 21 is wound in an endless manner.

When the wall frames a formed as described above are arranged in parallel in the vertical and horizontal directions, and the rain barriers and wind barriers of the adjacent wall frames are crimped and fixed to the frame, there is no space between the adjacent wall frames on the outdoor side. A gap 22 is formed in which the space is closed by a rain barrier 20 and the indoor side is closed by a wind barrier 21.

This spacing section 22 consists of a vertical spacing section 23 formed in a portion where the wall frames are adjacent to each other in the horizontal direction and a horizontal spacing section 24 formed in a portion where the wall frames are adjacent to each other in the vertical direction. Therefore, the whole has a square shape, but since the lid material 25 made of synthetic resin rubber is attached to the upper end of the vertical space part 23 to close it, the L U-shaped space part 0 is continuous in the horizontal direction. ing.

The lateral spacing section 24 of each wall frame runs in a series in the lateral direction, and is connected to the outside through the air intake hollow section 12 through the connecting row 5 and the entrance section 14, so that the pressure difference with the outside air is reduced. This is an isobaric layer with almost no space, and the vertical spacing section 23 whose lower end is open □ in the horizontal spacing section 24 is also an isobaric layer.
Therefore, even if rainwater enters the horizontal spacing section 24 along with air from the connecting row 5 through the air intake hollow section 12 from the closing section 14, or rainwater will soak into the respective spacing sections 23 and 24 from the contact surface of the rain barrier 20. Even if the space is flooded, the difference in pressure from the outside air is small and the pressure difference between the spaces is small, creating an isobaric layer, so the rainwater that seeps in naturally flows down from the connecting row 0 for rainwater drainage, through the hollow part 6, and from the drain hole 19 to the outdoor side. Since it is discharged into the room, it does not leak into the room.

Note that the hollow portion 12 of the lower cross member 2 may be partially opened in the longitudinal direction if necessary, and the open portion 14 and the connecting row 5 may be formed over the entire length in the longitudinal direction.

In the wall frame a described above, the glass pocket hollow part 11 of the lower horizontal member 2 reaches the glass pocket hollow part 16 of each vertical member 3 at both ends, and each glass pocket hollow part 16
The upper end of the upper cross member 1 fits into the end of the hollow part 5 for the glass pocket of the upper cross member 1.

Therefore, each hollow part 6, 11, 16 for glass pockets is a hollow hollow mutually continuous, and if a window hole 26 suitable for the outside is opened in the lower surface of the hollow part 11, each hollow part 5, 11, 16 can be exposed to the outside air. This creates an isobaric layer with a small pressure difference. Therefore, each hollow part for a glass pocket has the same effect as the above-mentioned space part, and rainwater does not seep in through the gaps between the glass plate and the glass bead, and between the glass bead and the glass pocket.
Even if it penetrates, it will flow down by gravity and be discharged through the window hole 26. In summary, according to the present invention, a rain barrier on the outdoor side and a wind barrier on the indoor side are provided on the outer periphery of a wall frame assembled in a frame shape by upper and lower horizontal members, left and right vertical members, and plate materials, and the wall frame is installed in the vertical direction. The gap formed by the rain barrier and wind barrier, which are in close contact with each other between adjacent wall frames while being fixed to the building frame in parallel in the horizontal direction, is connected to the outside through the opening of the lower horizontal member, and the outside air is allowed to pass through. This is an isobaric layer with a small pressure difference.

Therefore, no matter where rainwater infiltrates, it is drained away by natural flow, resulting in extremely good rain control.
Then, the connection port for rainwater discharge, which was opened on the upper surface of the hollow part for draining rainwater of the upper equipment, is closed into the gap formed by the rain barrier and the wind barrier, and the connection port for rainwater is closed from the hollow part for air intake of the lower horizontal member. Rainwater that flows into the space and rainwater that flows from the contact surface of the rain barrier is guided from the rainwater drainage connection port to the rainwater drainage hollow part of the upper horizontal member and discharged to the outdoor side of the rain barrier. Since rainwater does not accumulate in the space and seep into the indoor side, and rainwater discharged from the interval flows only onto the outdoor surface of the vertical members, vertical stains due to rainwater do not occur on the exterior wall surface.

In addition, since the exterior wall surface can be constructed by simply arranging the frame-like wall frames in parallel and fixing them to the building frame, the construction work efficiency and period remain the same as before, and it is also extremely effective in on-site construction. Furthermore, by using neoprene rubber, silicone rubber, etc., which have little deterioration over time, the wind barrier and rain barrier can be expected to be effective in keeping out rain over a long period of time.
