2. Description of the Related Art As the above-mentioned rain end structure, upper and lower frames, left and right vertical frames are framed by communicating hollow parts integrally formed in each frame with each other, and on the upper frame top wall located below the outer wall of the body, A backup rib and a rising wall are provided at the front and rear positions sandwiching the inner surface of the outer wall, and the upper end of the outer wall in the vertical direction of the vertical frame is used as the end wall that is in contact with these ribs and the long end of the rising wall. The dish-shaped water receiving part is formed on the upper side, and the water (condensation water, rainwater that infiltrates from the joints of the outer wall, etc.) generated on the inside of the outer wall of the body is received by the water receiving part, and the upper frame is drawn from the drain hole at the bottom of the water receiving part. Through the hollow part of the vertical frame to the hollow part of the vertical frame, and through the hollow part of the lower frame, the water is drained to the outside from the drain hole provided in the lower frame (Act No. Sho 56-4153) The frame is composed of a support frame and a frame body, and the upper and lower, left and right frames are the support frame and the frame body, respectively. In the state that these spaces are formed and these frames are framed, the spaces communicate with each other, the water generated inside the outer wall chamber flows through the space inside the upper frame, flows into the space inside the vertical frame, and the lower frame There is known one that is discharged to the outside through the inner space (JP-A-60-123692).

[0003]

In the above description, water reaching the end of the dish-shaped water receiving portion is guided to the vertical frame hollow portion through the hollow portion of the upper frame, and then the hollow portion of the lower frame. Is discharged to the outside through the. In general, aluminum sash frames are surface treated to prevent them from being corroded by water, etc.In a sash frame in which the hollow part is integrally molded, the surface treatment is due to the nature of the treatment. The surface treatment is not performed on the hollow portion inside the sash frame. Therefore, in the above, since the structure is such that the water is drained through the hollow portions of the upper frame and the lower frame, water easily adheres to the hollow portions, and as described above, the hollow portions are subjected to surface treatment for corrosion resistance. Therefore, there is a drawback that the hollow portions of the upper and lower frames are likely to be corroded by moisture.

Next, the upper frame, the lower frame, etc. are composed of a frame body and a support frame, and the frame body of the sash frame which forms a space in the upper frame and the lower frame which serves as a passage for water. Since the wall surface of is effectively surface-treated, corrosion does not occur even if water passes through the space, but since each frame is composed of the frame body and the support frame, There was a problem that the number of points was large and the labor of assembly and processing increased. In view of the above-mentioned conventional technique, an object of the present invention is to provide a rain siding structure of a sash frame that is integrally provided with a hollow portion and that does not require assembly and processing, and that does not cause corrosion.

According to this, the water generated inside the outer wall member
Is introduced directly into the hollow part of the vertical frame through the drainage channel?
Water does not enter the hollow part of the upper frame, so
Corrosion is prevented. Also, the drainage channel is the upper ceiling primary sealing.
Since it is also configured to use the back surface of the material, the room is separately
It is necessary to provide an upward wall that forms a drainage channel in cooperation with the inner wall.
There is no need, and the shape of the upper frame can be simplified. Further, since the hollow portion of the lower frame also does not serve as a passage for drained water, corrosion of the hollow portion of the lower frame is avoided in addition to the upper frame.

The upper end closing member is a closing cap fitted in the upper end of the vertical frame hollow portion, and the inner side surface of the closing cap in the finding direction cooperates with the inner wall of the vertical frame hollow portion in the finding direction to hollow the upper frame. Is formed on the end face closing surface that closes the open end of the portion, and the closing cap is provided with a through hole as a water guiding portion, and the drainage channel flows to the outer side position in the finding direction with respect to the through hole.

However, in the assembled state, since the upper end of the base wall 15 of the vertical frame 3 is not cut in an inclined shape in accordance with the hollow portion cross-sectional shape of the upper frame 2 with respect to the hollow portion 5 of the upper frame 2, The open end 5a of the portion 5 is not completely closed, and a small triangular portion remains, as shown in FIG. In order to close the triangular portion, a closing cap 25 shown as an upper closing member for closing the upper opening of the hollow portion 16 is fitted on the upper end of the vertical frame 3. Cap 2
5 has a fitting portion 25b projecting downward from the main body 25a and fitted into the hollow portion 16 of the vertical frame 3. Body 25a
The upper surface of the above is formed into an inclined surface 25c which is flush with the upper surface of the upper wall 6 of the upper frame 2 with the fitting portion 25b fitted in the upper end of the hollow portion 16. The inner side surface of the main body 25a in the finding direction is an end surface closing surface 25d that is flush with the inner wall surface of the base wall 15 of the vertical frame 3 in the fitted state. A waterproof seal is sandwiched between the end face closing surface 25d and the opening end 5a of the upper frame 2 to close the triangular portion, and thus the hollow portion 5 of the upper frame 3 has its longitudinal ends. The face is completely sealed.

The main body 25a of the closing cap 25 is provided with a rising piece 25e which is continuous with the mounting piece 7 of the upper frame 2. A through hole 25f exemplified as a water guiding portion located in a drainage channel 51 described later is provided slightly outside the rising piece 25e so as to penetrate the main body 25a, and the upper end opening portion of the vertical frame hollow portion 16 is provided. In the above, the outdoor side from the through hole 25f, that is, the outdoor side from the indoor surface of the upper frame primary sealing material 50 is closed by the inclined surface 25c of the main body 25a. A water stop member 25g for damming the water flowing through the drainage channel 51 is provided outside the through hole 25f in the finding direction. The water stop member 25g blocks the rising piece 25e from the outdoor side hanging piece 8a of the upper auxiliary frame 8. Is raised upward across the width of the drainage channel 51 with a gap T in which is attached. The lower end opening of the hollow portion 16 of the vertical frame 3 is closed by the lower end closing member 30. The lower end closing member 30 is provided with a drainage hole 31 as a drainage portion at a position on the outside of the lower frame primary sealing material 53, which will be described later.
The outdoor side portion is closed from the indoor surface of the lower frame primary sealing material 53 continuous with.

The skeleton 40 is provided with an extruded cement plate 41 having a predetermined size as an outer wall member, and a beam member 42 for holding the extruded cement plate 41 and for attaching the window frame 1. . In the frame opening 43 surrounded by the cement plate 41, the upper and lower sides of the framed window frame 1, the vertical frame 2,
3, 4 are fixed to the beam member 42 via anchor metal fittings 44. The outdoor surface of the extruded cement board 41 is located slightly on the indoor side from the outdoor surface of the window frame 1, and the indoor side surface of the cement board 41 is located at substantially the same position as the indoor side end position of the window frame 1. is there. With respect to the fixed window frame 1, the upper wall 6 of the upper frame 2 and the skeleton opening 43 are sealed at an outdoor side position that is separated from the indoor side wall (the outdoor side hanging piece 8a of the upper auxiliary frame 8) by a predetermined distance. The upper frame primary sealing material 50 is provided to form the drainage channel 51 between the upper frame primary sealing material 50 and the indoor side wall. The drainage channel 51 extends to the water stop member 25g and directly communicates with the through hole 25f. Upper frame 1
The next sealing material 50 is provided with the vertical frame primary sealing material 52 interposed between the vertical frame 3 and the opening 43, and the auxiliary lower frame 65 that seals and attaches between the lower frame 4 and the cement plate 41. Is continuous with the lower frame primary sealing material 53 which is interposed between the frame frame opening portion 43 and the frame frame opening portion 43, whereby a watertight seal is provided between the window frame 1 and the opening portion 43. . Further, the vertical auxiliary frame 5 attached to the upper auxiliary frame 8 and the vertical frame 3
5 and the lower auxiliary frame 56 attached to the lower frame 5 and the opening 43 are provided with a secondary sealing material 60 that seals the indoor side of the drainage channel 51 over the entire circumference of the window frame 1. .
A backup material 61 is provided on the back side of each of the primary sealing materials 50, 52 and 53 and the secondary sealing material 60. In the upper frame 3, between the upper frame primary sealing material 50 and the backing material 61 on the back surface thereof, or between the backup material 61 and the upper frame secondary sealing 60, or the upper frame upper wall 6 and the backup material 61. , There is a gap between the outdoor-side hanging piece 8a of the upper auxiliary frame 8 and the backup material 61, water passes through the gap, and the drainage channel 51 functions. Another sealing material is provided between the primary and secondary sealing materials 52, 60 of the vertical frame 3 on the outer side in the mounting direction of the backup material 61 with the frame 40.

The beam member 42 is an L-shaped angle member as is clear from the figure, and in particular, the beam member 42 on the upper side of the window frame 1 is L-shaped.
The angled tip of the letter just reaches the tip of the drainage channel 51 and constitutes a water guide member for indoor / outdoor directions. Also,
The beam member 42 having a predetermined length in the longitudinal direction is connected in the middle of the length of one window frame, and an L-shaped flushing 66 having a predetermined length is provided at the joint portion thereof on the outdoor surface of the beam member 42. Is held by the cement plate 41, and the tip of the flushing 66 reaches the upper part of the drainage channel 51, which also constitutes a water guide member.

According to the above construction, the dew condensation water generated on the indoor side of the cement board 41 and the rainwater entering the inside of the cement board 41 from the joints between the cement boards 41 are flushed by the flushing 66 or the L-shaped angle. It is guided by the beam member 42 made of wood or directly flows into the drainage channel 51.
The inflowing water flows through the drainage channel 51 on the upper wall 6 of the upper frame 2 to the end of the window frame 1, and when reaching the end of the drainage channel 51,
It does not enter the hollow portion 5 of the upper frame 2 through the through hole 25f but directly flows into the hollow portion 16 of the vertical frame 3 and is discharged as it is from the drainage hole 31 at the lower end of the vertical frame 3 to the outside of the room. Therefore, since water does not pass through the hollow portions 5 and 21 of the upper and lower frames 2 and 3, there is no corrosion of these hollow portions 5 and 21 which are not surface-treated. In addition, since the end of the drainage channel 51 is partitioned by the water stop member 25g, the water will exceed this and the vertical frame 3 1
It does not flow between the secondary and secondary sealing materials 52 and 60.

Up to now, the case of having one window frame has been described, but the same configuration can be adopted even in the case of a continuous window in which a large number of window frames 1 are arranged in parallel. In FIG. 6, a vertical frame portion of two adjacent window frames 1 is shown in a cross section similar to FIG. The vertical frames 3 of the adjacent window frames 1 are connected to each other by a continuous window stand 70 in the vertical direction, and are attached to the frame. Hollow part 16 and hollow part 1
A vertical frame primary sealing material 52 is interposed between the first and second vertical frames. Although not shown, the upper and lower closing caps and the lower end closing member of the vertical frame 3 are exactly the same as those in the above-described embodiment, and the drainage channels are also exactly the same. Therefore, in the case of this continuous window, the water flowing over the upper frame of each window frame is discharged out of the room through the vertical frame of the window frame.

In the above embodiment, since the upper shape of the vertical frame is cut into a shape orthogonal to the longitudinal direction, the vertical frame end can be easily processed, but the upper wall of the upper frame is inclined. According to the above, it may be cut obliquely. In this case, by joining the upper frame and the base wall of the vertical frame, the hollow portion of the upper frame is closed,
Although the closing cap having the above-mentioned end face closing surface is not necessary, the upper end and lower end closing members for closing the upper and lower end openings of the hollow portion of the vertical frame leaving the water guiding portion and the draining portion are necessary.

[0021]

As described above, according to the present invention, since the window frame is constructed by assembling the frame member integrally provided with the hollow portion, the assembly is easy. Then, the dew condensation water generated on the indoor side of the body outer wall member and the rainwater that has entered the outer wall inside from the joint portion of the body outer wall member are received by the drainage channel on the upper surface of the upper frame that has been subjected to the surface treatment. Since the water is guided directly to the hollow part of the vertical frame without passing through the hollow part of the frame, water does not enter the hollow part of the upper frame that is not surface-treated, and at least the hollow part of the upper frame is corroded. Can be prevented.

[0022] The drainage channel, since there is provided utilizing the upper frame primary sealant, separately, may not be provided on the frame wall upper frame constituting the drainage, the upper frame shape can be simplified.

Also, the hollow part of the vertical frame is made to pass vertically.
More, because wastewater does not pass even a lower frame hollow portion can be prevented even corrosion of the lower frame hollow portion.

In the case where the closing cap and the inner wall of the hollow portion of the vertical frame in the direction of finding are used together to close the end of the hollow portion of the upper frame, the upper end shape of the vertical frame does not have to match the upper frame shape. Since the end surface of the upper frame can be closed, the cutting processing shape of the upper end portion of the vertical frame can be a right angle shape, and the processing can be easily performed.

By applying the secondary sealing material to the indoor side of the primary sealing material, even if there is water trying to cross the drainage channel, it is possible to prevent this water from entering the indoor side, and it is excellent in watertightness.

In the case where the guide member for the indoor and outdoor directions is provided,
Even if the drainage channel is on the hollow portion of the upper frame and the indoor side surface of the skeleton outer wall member is separated from the drainage channel toward the indoor side, water generated on the indoor side of the outer wall member can be smoothly collected in the drainage channel.
