2. Description of the Related Art In recent years, aluminum sash windows have become widespread in many houses. FIG. 8 is a front view of an example of a mounting state of the sliding door type aluminum sash window A viewed from the outdoor side. The window frame 10 of the aluminum sash window A housed in the window opening is formed integrally, and In addition to having horizontal rails 11a and 11b, vertical rails 15a and 15b are provided on the left and right, and upper and lower left and right outer wall panels 20a and 20b on the upper and lower sides of the window frame 10 and right and left outer wall panels 20c adjacent to the window opening, 20d. The window frame 10 has a window glass 31.
Are slidably fitted.

FIG. 9 is a longitudinal sectional view of a mounting structure of a window frame 10 and FIG.
10 shows a V-V cross-sectional view of FIG. The window frame 10 is fixed by screws 2 to a wooden window enclosure 1 arranged on the indoor side. The outer wall panels 20a to 20d are respectively
An outer wall surface material 21 such as a hard wood chip cement board or the like, and a reinforcing member (frame) 22 attached to a peripheral portion of the outer wall surface material 21 on the indoor side are supported by columns and studs 23 and the like. ing.

A drain board 40 is provided between the upper portion of the window frame 10 and the outer wall panel 20a above the window opening, and between the lower portion of the window frame 10 and the outer wall panel 20b below the window opening.
The draining board 40 extends along the left-right direction of the window frame 10, and has a length substantially equal to that of the window frame 10 and the outer wall panels 20a and 20b. The draining plate 40 has an inclined portion 41 that is disposed at a downward slope in the outdoor direction between the window frame 10 and the outer wall panels 20a and 20b. A lower extension 42 extending downward from the end is disposed in contact with an upper end of the outer wall panel 20b on the outdoor side, and an upper extension 43 extending upward from the indoor end of the inclined portion 41 is formed in the chamber of the window frame 10. It is arranged in contact with the inside rear surface. On the upper side of the window frame 10, the inclined portion 4

b is arranged in contact with the rear surface of the upper end portion on the indoor side.

A drain cap 50 made of rubber as shown in FIG. 11 is fitted to both longitudinal ends (left and right ends) of the drain plate 40. The draining cap 50 has a flat prismatic shape as described in, for example, Japanese Utility Model Laid-Open No. 58180/1988, and has a slit 60.
have. This slit 60 is a drainer cap 50
Are open on the indoor side surface, the outdoor side surface, and the side surface located on the draining plate 40 side, and are formed with a downward slope from the indoor side to the outdoor side. The slope of the slit 60 is the same as the slope of the inclined portion 41 of the draining plate 40, and the thickness of the slit 60 is substantially equal to the thickness of the inclined portion 41 of the draining plate 40. The slit 60 of the drainer cap 50 is fitted in close contact with the end of the inclined portion 41 of the drainer plate 40. The end face of the inclined portion 41 has a slit 6
Close to the back end of 0. Since the draining cap 50 is fitted to the end of the inclined portion 41 of the draining plate 40 in this manner, rainwater does not flow to the rear surface of the draining plate 40, that is, the indoor side.

As shown in FIG. 12 , the outer wall panels 20b above and below the window opening
When the left-right end face 100 of the window frame 10 protrudes toward the joint 71 from the left-right end face 200 (only the lower side is shown in this drawing), that is, a step occurs between the window frame 10 and the outer wall panel 20b. In this case, the gasket 70 does not adhere to the outer wall panel 20b, the window frame 10, the draining cap 50, and the like, and a gap 75 is generated, which may cause water leakage.

The present invention has been made in view of the above circumstances, and provides a seal structure for an outer wall joint which can reliably seal even when a gap due to a step occurs in a joint to be sealed with a gasket. It is an object.

[0009]

In order to solve the above-mentioned problems, the invention according to claim 1 is directed to a first outer wall panel and a second outer wall panel located adjacent to the first outer wall panel in the left-right direction. A continuous gasket is inserted into a joint and a second joint between the first outer wall panel and a third outer wall panel located adjacent to the first outer wall panel in the left-right direction and vertically above the second outer wall panel. A drain board extending in the left-right direction is inserted between the second outer wall panel and the third outer wall panel,
In the sealing structure of an outer wall joint, a drainer cap for sealing an end on the joint side between the second outer wall panel and the third outer wall panel is fitted to an end of the drainer on the joint side. The recess in the joint formed at the boundary between the first joint and the second joint due to a step between the left and right end face positions of the second outer wall panel and the left and right end face positions of the third outer wall panel, It is characterized by being covered with a waterproof filling member which is soft and lower than the hardness of the gasket.

According to a second aspect of the present invention, a first joint between a first outer wall panel and a second outer wall panel located adjacent to the first outer wall panel, and the first outer wall panel and the left and right sides thereof are provided. A continuous gasket is inserted into a second joint between the second outer wall panel and the window frame, the second gasket being inserted between the second outer wall panel and the window frame. A draining plate extending in the left-right direction is inserted into the draining plate, and a draining cap for sealing the joint-side end between the second outer wall panel and the window frame is fitted to the joint-side end of the draining plate. In the sealing structure between the window frame and the outer wall, the step between the left and right end face positions of the second outer wall panel and the left and right end face positions of the window frame causes a step between the first joint and the second joint. The resulting concave portion in the joint is made softer than the hardness of the gasket. It is characterized in that closes at a lower waterproof packing member.

According to a third aspect of the present invention, the drain cap is formed of the waterproof filling member, and the joint end of the drain cap projects toward the gasket so as to be pressed by the gasket. Thus, the joint recess is closed.

Furthermore, in the invention according to claim 4, the joint end of the drain cap is formed from the waterproof filling member, and the joint end of the drain cap is pressed by the gasket. By projecting to the gasket side, the concave portion in the joint is closed.

[0013]

In the sealing structure according to the present invention, the first joint is formed by a step between the left and right end face positions of the third outer wall panel (or window frame) and the left and right end face positions of the second outer wall panel. When the width between the second joint and the second joint is different, the concave portion (gap) generated by the step is closed with a waterproof filling member. Since this waterproof filling member is soft and lower than the hardness of the gasket, it is reliably and completely closed by the pressing force of the gasket to be waterproofed.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. First Embodiment First, a first embodiment will be described. 1 and 2
FIG. 1 is a schematic perspective view showing a joint structure in which a window frame 10 (vertical bar portion 15a) protrudes to the joint side from the outer wall panel 20b. FIG. 1 shows a joint structure before a gasket 70 is inserted. 2 is a gasket 7 according to the first embodiment of the present invention.
The structure of the joint after insertion of 0 is shown. 3 and 4 show that the outer wall panel 20b has the window frame 10 (vertical bar 15a).
FIG. 3 is a schematic perspective view showing the structure of the joint portion projecting further toward the joint, FIG. 3 shows the structure of the joint portion before the gasket 70 is inserted, and FIG. 4 is a gasket according to the first embodiment of the present invention. The structure of the joint after the insertion of the joint 70 is shown.

The seal structure of this embodiment is substantially the same as that shown in FIGS. 6 to 10 except for a change in the shape of the joint side end of the drain cap 51, which is caused by the fact that the material of the drain cap 51 is different from that of the conventional one. Therefore, the same components as those in FIGS. 6 to 10 are denoted by the same reference numerals and description thereof is omitted. The drainer cap 51 used in the seal structure of this example first has a structure in which the gasket 70 is inserted.
As shown in FIGS. 1 and 3, the joint-side end is arranged so as to protrude toward the joint 71 (gasket 70 side) so as to be pressed by the gasket 70 (when the gasket 70 is inserted). At this time, as shown in FIG. 1, when the window frame 10 protrudes to the joint side from the outer wall panel 20 b, the horizontal direction end surface position 100 of the window frame 10 and the horizontal direction end surface of the protruding portion 53 of the drain cap 51. When the outer wall panel 20b protrudes more toward the joint side than the window frame 10 as shown in FIG. 3, the outer wall panel 20b has a left-right end face position 200 and a drain cap 51 as shown in FIG.
And the left and right end face positions of the projecting portion 53 are substantially matched.

The draining cap 51 is similar to the conventional draining member 50 in that it has a flat prismatic shape.
It is formed longer. Here, the size of the protruding portion 53 is set slightly larger than the expected gap (FIG. 10). In this example, the gasket 70 and the drain cap 51 are provided with a difference in hardness.
The hardness of the drain cap 51 is lower than the hardness of the drain cap 51. For example, the hardness of the gasket 70 is set to 70 to 80 degrees, and the hardness of the drain cap 51 is set to 30 degrees. Further, in this example, as a material of the gasket 70,
Synthetic rubber such as EPDM (ethylene-propylene-diethane-polymer) or CSM (chlorosulfonated polyethylene) is used. Further, as a material of the drain cap 51, a soft silicone rubber which is rich in deformation followability is used.

After the drainer cap 51 of this embodiment is set in the state shown in FIG. 1 or FIG. 3, the gasket 70 is inserted from the outdoor side. At this time, the protruding portion 53 of the drain cap 51 mutually presses the gasket 70,
The left and right end faces 1 of the window frame 10 are
00 and the lateral wall end face 200 of the outer wall panel 20b. At this time, since the anti-compression force acts on the projecting portion 53 of the drain cap 51 everywhere, the recess (gap) is completely filled as shown in FIG.

FIG. 5 is a schematic perspective view showing a modification of this embodiment. In the above embodiment, the drainer cap 51 is
Although the drainage cap 52 of this example is configured as an integral product including the protruding portion 53, only the protruding portion 54 is formed of a hydrophobic urethane foam having a lower hardness than the gasket 70. The draining cap 50 shown in FIG. By doing so, the same effect as in the above embodiment can be obtained more easily.

Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 6 is a cross-sectional view showing the structure around the underbuilding, and FIG. 7 is a perspective view schematically showing the structure of the joint around the underbuilding. As shown in these drawings, even when the undercarriage 81 is attached, the joint structure around the undercarriage 81 shown in FIG.
Are likely to occur. That is, the shed 81
Is attached to a shed mounting outer wall panel 82b made of plywood. The lower building outer wall panel 82b is adjacent to the upper floor outer wall panel 82a in the left-right direction and the upper floor outer wall panel 82b.
c is disposed next to and below. For this reason, the horizontal joint 83 appears between the lower house outer wall panel 82b and the upper floor outer wall panel 82c, and the upper floor outer wall panel 82a and the lower house outer panel 8
A vertical joint 84 appears between the upper floor 2b and the upper floor outer wall panel 82c. In order to prevent rainwater from entering the room side from the horizontal joint 83, a drain board 85 having substantially the same configuration as the drain board 40 is attached to the horizontal joint 83, and the vertical length of the drain board 85 in the left-right direction. A flexible drain cap 86 having the same configuration as the drain cap 51 in the first embodiment is fitted to the joint 84 side end. At this time, the upper floor outer wall panel 82c is longer than the lower wall mounting outer wall panel 82b by the vertical joint 84.
In the case of projecting to the side, as shown in FIG. 6, the left-right end face position 800 of the upper floor outer wall panel 82 c and the left-right end face position of the protruding portion of the drain cap 86 are substantially matched. On the other hand, when the undercarriage mounting outer wall panel 82b protrudes more toward the vertical joint 84 than the upper floor outer wall panel 82c, as shown in FIG.
And the left and right end face positions of the protruding portion of the drain cap 86 are substantially matched. In this state, if a gasket (not shown) is inserted into the vertical joint 84, as described in the first embodiment, the outer wall panel 8 for attaching a shed
The gap at the stepped portion caused by the mismatch between the left-right end face of the upper floor outer wall panel 82c and the left-right end face of the upper floor outer wall panel 82c is completely and reliably filled by the soft drain cap 86. In FIG. 6, reference numeral 87 indicates a drainer cover, and reference numeral 88 indicates a rain gutter. It is needless to say that the modification of the first embodiment can be applied to this example.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and there are design changes and the like that do not depart from the gist of the present invention. Is also included in the present invention. For example, in the above-described embodiment, when the window frame 10 protrudes to the joint side from the outer wall panel 20b, the left and right end face positions 1 of the window frame 10
Although 00 and the left and right end face positions of the projecting portion 53 of the drainer cap 51 are made substantially coincident with each other, the projecting portion 53 may be made to project slightly from the window frame 10. Similarly, in the above-described embodiment, when the outer wall panel 20b projects beyond the window frame 10 toward the joint, the outer wall panel 20b
The left and right end faces 200 and the left and right end faces of the projecting portion 53 of the drain cap 51 are made substantially coincident with each other, but the projecting portion 53 may be made to project slightly from the outer wall panel 20b.

In the above-described embodiment, the projecting portion 53 is provided on the draining cap 51. Alternatively, by extending the draining plate 40 in the length direction, the draining cap can be connected to the joint side. Can also be projected. Further, in the above-described modified example, the case where the protruding portion 54 is configured by a hydrophobic urethane foam has been described. However, the present invention is not limited to this, as long as the foam is a hydrophobic foam, a conventionally known foam, For example, urethane foam, styrene foam, and phenol foam may be used.

Further, in the other embodiment described above, a case was described in which the hydrophobic urethane foam was attached to the joint side end face of the drainer cap 50. However, instead of this, these are provided as separate members. After or at the time of mounting the gasket, for example, a waterproof filling member such as a hydrophobic urethane foam may be fitted and filled in the concave portion (gap). Further, in the above-described embodiment, the drainage cap attached to the lower left of the window frame has been a problem. However, it is needless to say that the present invention can be applied to the drainage cap attached to the lower right, upper left, and upper right of the window frame. .

[0023]

As described above, the seal structure of the present invention has a step between the left and right end face positions of the third outer wall panel (or window frame) and the left and right end face position of the second outer wall panel. In the case where the width of the first joint and the second joint is different from each other, the concave portion of the step is filled with a soft waterproof filling member having a hardness lower than the hardness of the gasket, so that the seal is formed. It is assured and water leakage can be prevented. Also, the construction is simple because the dry construction method without using caulking material is sufficient. Further, if the projecting portion is formed of another waterproof filling member and is attached to the side surface of the drainage cap, it can be easily realized because it can be applied to an existing drainage cap.
