Description of the Related Art Conventionally, in order to prevent water leakage between the sash and the skeleton, an outer seal is attached between the outer peripheral surface of the sash and the inner peripheral surface of the skeleton opening, and a waterproof mortar mixed with a waterproofing agent is appropriately filled. Was. However, in such a method, the water outside the room may get into the room due to various causes such as a problem in the waterproof performance of the mortar, incomplete construction, deterioration of the sealing material, and cracking of the mortar. Easy to penetrate.

Further, in order to treat the dew condensation water generated on the indoor side surface of the sash, a dew condensation water receiving angle member is attached along the indoor side surface of the lower frame. However, since the lower surface of the lower frame is usually filled with mortar and water that has dropped onto the angle material cannot be discharged to the outside of the room, there is a risk that the angle material will overflow to the indoor side if a certain amount or more of water accumulates. . Therefore, on the lower side of the inner peripheral surface of the opening of the building, a draining plate with a horizontal cross-sectional shape that appropriately covers this, which inclines downward to the outdoor side and has a lower frame supporting portion protruding from the upper surface, is attached to support the lower frame. The lower frame of the window is attached to the section with a screw so that the water leakage between the window frame and the opening of the building is received by the draining plate and discharged to the outside of the room. It has been proposed as an issue.

However, since the end on the indoor side of the lower frame of the draining plate is formed horizontally and there is no means for preventing the infiltration of water, water leakage or dew condensation that has fallen on the horizontal portion is caused. Water easily flows into the room, and if cracks occur in the mortar that is placed between the outer periphery of the sash and the inner peripheral surface of the opening, the water that flows in from here moves downward along the outer periphery of the sash and the vertical frame Water leaks from the lower end of the room.

[0005]

A drainage path from 1 to the trough-like space 19 of the draining plate 4 is configured.

To build this sash window 1 in the frame 2,
After attaching the draining plate 4 to the lower side of the inner peripheral surface of the opening 3 as in the first embodiment, the sash 7 is fitted inside the opening 3 and the projection 18 of the lower frame 5 is attached to the lower frame engaging member of the draining plate 4. While engaging with the mating groove 16, the lower end of the standing wall 17 is brought into contact with the upper surface of the lower frame receiving piece 28, and the standing wall 17 and the lower frame fixing wall 29 are screwed.
In the drawing, the draining side plates 34 are not provided at both ends of the draining plate 4, but if necessary, they may be provided similarly to the first embodiment.

In the second embodiment, the mortar 14 'filled between the outer circumference of the sash 7 and the inner circumference of the opening is the weir wall 3.
It is constructed on the outdoor side based on 1 and the weir wall 3 at the bottom.
1 prevents the mortar from flowing into the drainage channel 19. This secures a water conduit between the outer peripheral surface of the sash 7 and the drainage channel. The other parts of the sash window 1 are substantially the same in construction and construction as those of the first embodiment, and therefore the same parts are designated by the same reference numerals and the description thereof will be omitted.

FIGS. 8 to 10 show a third embodiment of the first embodiment.
In comparison with the embodiment of FIG. 4 (FIG. 4), the mortar blocking member 1
3 is configured by a water receiver 37. Also,
The length of the draining plate 4 is substantially the same as the lower frame 5 of the sash 7. The water receiver 37 is integrally formed with a horizontal receiving portion 38 and a vertical guiding portion 39 connected to the horizontal receiving portion 38, and has a groove shape facing upward as a whole. In the water receiver 37, the sash 7 is mounted on the draining plate 4, then the guide portion 39 is hooked on the drainage channel 19, and the horizontal receiving portion 38 is attached to the vertical frame 15 of the sash 7.
When the mortar 14 'is filled between the inner peripheral surface of the opening 3 and the outer periphery of the sash 7, it is fixed to the sash window 1 at the same time. The mortar is filled in the outdoor side with respect to the outdoor side wall of the water receiver 37, and since the guide part 39 of the water receiver 37 becomes a form that shields the end of the drainage channel 19, Mortar is prevented from flowing. After all, the water receiver 37 is one of the mortar blocking members for preventing the mortar from flowing into the drainage channel 19 and securing a water conduit between the outer peripheral side of the sash 7 and the drainage channel 19. Since the other constructions and effects are almost the same as those of the first embodiment, detailed description will be omitted.

Although the illustrated embodiment has been described above, the present invention is not limited to the illustrated specific configuration. In the first embodiment, the draining plate 4 is larger in length and width than the lower frame 5 of the sash 7 and protrudes from the indoor side surface of the lower frame 5 to the indoor side and from the outdoor side surface of the lower frame 5 to the outdoor side. However, the edge on the outdoor side has been described as protruding further outward than the frame 2, but the draining plate 4 may have substantially the same length and width as the lower frame 5 of the sash 7. . In that case, the mortar blocking member 13 is arranged so as to fit into the drainage channel at the end of the drainage channel 19. In the second embodiment, the drainage channel 19 is constituted by the water return wall 9 and the lower frame fixing wall 29 which is erected in parallel with the water return wall 9. However, as shown in FIG. It is also possible to configure the drainage channel 19 between the lower frame support wall 10 and the water return wall 9 configured as described above. That is, the lower frame support wall 10 can also be an outdoor wall forming the drainage channel 19. In this case, the draining plate 4 of the lower frame support wall 10
A portion protruding laterally from the end portion (side of the broken line) serves as a weir wall 31. As shown in the figure, the lower frame support wall 10 or the lower frame fixing wall 29 may have no central portion and exist only at the end of the draining plate 4.

As shown by the broken line in FIG. 11, the weir wall 31 may not be formed on the lower frame support wall 10 or the lower frame fixing wall 29. Even with this structure, the end portion of the lower frame support wall 10 or the lower frame fixing wall 29 can prevent the mortar from flowing into the drainage channel 19 to some extent at the time of filling the mortar, thus forming a mortar blocker. ing. However, when a mortar blocking member such as a sponge is also used at the end of the drainage channel of this structure, the mortar blocking effect and the water conduit formation effect are increased. It should be noted that the sash lower frame 5 and the draining plate 4 are usually connected to each other on the lower frame supporting wall 10 outside the water repelling wall 9.
It is usually performed between the sash 7 and the sash 7 on the water return wall 9 with screws or the like. In that case, to prevent rainwater from leaking to the indoor side,
A sealing material is applied to the screw portion connecting the sash 7 and the water return wall.

[0029]

According to the first and second aspects of the present invention, even if rainwater may enter from the mortar portion filled between the sash and the skeleton, the rainwater can be promptly guided to the outdoor side. It will not leak out to the indoor side. Further, the water condensed on the inner surface of the sash is also guided to the outside of the room through the drainage channel. As a result, there is no concern that leaked water and condensed water will flow into the room and deteriorate the living environment. Higher skill is not required for mortar or seal material construction, and work efficiency is improved.

Further, if the draining plate is attached to the frame with high precision in advance, the sash can be accurately positioned only by fitting the sash into the opening and mounting the lower frame on the upper surface of the draining plate. Since there is no need to make subtle adjustments to the installation, it is possible for construction workers with no specialized skills to easily and consistently perform construction, shortening the construction period and reducing costs. To be done. According to the configuration described in claim 2, since the mortar is prevented from flowing into the indoor side toward the drainage channel by the outer wall forming the drainage channel during construction, a member separate from the lower frame is used. It is possible to configure the mortar blockage means without the need.

According to the structure described in claim 3, since the draining plate is larger than the sash lower frame, the water treatment at the end portion of the lower frame becomes more reliable. Further, since the mortar blocking member that forms the water conduit is arranged so as to project to the side of the sash vertical frame, it is possible to reliably guide the inflow water that propagates downward along the outer periphery of the sash vertical frame to the drainage channel. . According to the configuration described in claim 4, the mortar blocking means is inexpensive and
Can be easily installed. According to the configuration described in claim 5, since the mortar blocking means is formed in the sash window as the structure of the sash window, the mortar blocking member as a separate component is not required, and the construction is easy. ,
There is no need to worry about deterioration of the mortar blocking means.

According to the structure described in claim 6, the effect of blocking the mortar is high, and the water conduit can be reliably obtained. According to the configuration described in claim 7, the drainage channel and the drainage space are surely communicated with each other, and the inflow water can be reliably discharged.
According to the structure described in claim 8, since the space between the sash and the skeleton is blocked indoors and outdoors, even if there is water that has entered the mortar through cracks, this water is guided to the tight material. It is possible to further improve the structure for preventing the intrusion of rainwater by falling on the drainboard. According to the structure described in claim 9, in the case of a sweep window or the like, it is possible to eliminate the deep groove between the floor surface on the indoor side and the lower frame of the sash to avoid danger and improve the appearance. According to the structure described in claim 10, rainwater flowing down on the outdoor side surface of the sash window is also reliably received by the draining plate and discharged, so that the rainwater circulates to the back side of the draining plate and eventually the inside of the indoor side. It will never leak.
