- the other components are the same as those in FIG. 5 of the first embodiment, and are denoted by the same reference numerals and description thereof is omitted.
- FIG. 18 is a horizontal sectional view taken along line VV in FIG. In this drawing, the left end of the upper right unit 200 and the right end of the upper left unit 400 are shown connected.
- FIG. 19 is a horizontal sectional view taken along the line VI in FIG. In this drawing, the left end of the lower right unit 100 and the right end of the lower left unit 300 are shown connected.
- the first vertical wall 510 is further laterally located substantially at the center of the main end vertical member 501b constituting the vertical frame 354 of the upper right unit 200 in the lateral direction toward the upper left unit 400.
- a second vertical wall 511 and an indoor vertical wall 520 extend from the indoor end of the main end vertical member 501b.
- the approximately vertical force of the main end vertical member 501d of the vertical frame 353 of the upper left unit 400 corresponds to the third vertical wall 530 in the horizontal direction toward the upper right unit 200 and the first vertical wall 510 of the upper right unit 200
- a fourth vertical wall 540 is further extended at the position where the vertical wall 540 extends, and a vertical force 550 on the indoor side of the main end vertical member 501d is further extended.
- LS and RS indicate sealing materials used in a gasket-type connection structure.
- an elastic sealing material LS is attached to the distal ends of the first vertical wall 510 and the second vertical wall 511 so as to extend over the entire length of the unit in the height direction.
- the elastic sealing material RS is attached to the distal end portions of the third vertical wall 530 and the fourth vertical wall 540 so as to extend over the entire length in the height direction of the unit (FIG. 20-). See also Figure 23).
- the first glass panel fixing portions 502b and 502d and the main end vertical member 501b , 501d, the first vertical wall 510, and the fourth vertical wall 540 constitute an outdoor constant pressure chamber 500B.
- the first vertical wall 510, the second vertical wall 511, the fourth vertical wall 530, the fourth vertical wall 540, and the elastic sealing materials LS and RS form a seal portion 500C.
- each vertical member constituting the glass panel mounting portion 500A, the outdoor equal pressure chamber 500B, the sealing portion 500C, and the indoor equal pressure chamber 500D is formed over the entire length of each unit except for the connecting portion.
- a gap formed between the tip of the indoor-side vertical wall 520 and the tip of the indoor-side vertical wall 550 is closed by the elastic piece 560 attached to the tip of the indoor-side vertical wall 520.
- substantially U-shaped end elastic sealing members 700a are provided on the left and right ends of the upper frame 301 and the ridges 302, 303 of the left and right lower units 100, 300 in FIG. 700c is attached (see also Figure 20 and Figure 22).
- the end elastic sealing members 700a and 700c are made of a material such as urethane foam and are integrally formed by embedding a U-shaped metal reinforcing member in the same manner as in the first embodiment. The same.
- the upper and lower cutouts are fitted with the interlock-type uneven connecting portions, and the left and right units are joined with the gasket-type connecting portions.
- a continuous seal can be formed between the left, right, upper and lower units as follows.
- the upper frame 401 of the upper right unit 200 is fitted to the lower frame 301 of the lower right unit 100, and then the lower frame 301 of the upper left unit 400 and the upper frame 200 of the upper left unit 300 are fitted to the upper frame 401 of the lower left unit 300.
- the vertical frames 353 and 354 of the upper left unit 400 are sequentially connected.
- the horizontal sealing portion formed by the horizontal elastic sealing material 305 is continuous between the left and right adjacent units via the end elastic sealing material 700 located at the intersection. This is the same as in the first embodiment.
- the vertical seal portion formed by the elastic seal members RS and LS extending over the entire length of the vertical frame is also interposed between vertically adjacent units via the end seal member 700 located at the intersection. Become continuous.
- the upper ends of the elastic seal members RS and LS are connected to the end elastic seal member 700.
- the lower left unit 300 and the lower right unit 100 as a whole form a vertical seal portion that continues to the end elastic seal member 700.
- the lower ends of the elastic sealing materials RS and LS are connected to the end elastic sealing material 700.
- the upper right unit 200 is formed with a vertical seal portion that continues to the end elastic seal material 700.
- each unit since each unit does not have the interlock-type uneven fitting portion for connecting the left and right units, the unit is installed on the building wall surface. It is possible to increase the degree of freedom of the installation work, which does not need to be installed in one direction in order.
- the elastic sealing materials are arranged on the left and right sides of all the units.
- only one unit of the unit in the horizontal row is used. It may be configured so that the elastic sealing material is provided only on one side of the unit. In such a configuration, when the last unit in the horizontal direction is attached, there is no need to shift the left and right units sideways in the conventional attachment.
- one of the left and right sides is connected to the adjacent unit by the conventional interlocking method, and this part is used as a fulcrum, and the other side is as if an open door is closed. , Can complete the integration.
