The frame 2 is connected and at the part, the outdoor side and the indoor side are completely cut off over four turns.

The bracket 21 is a piece member or a long member. However, in the case of a long member, through holes are formed at appropriate places to communicate the space between the lower spacer portion 3b and the old lower frame with the outside air, The space C is formed as an isobaric space.

Then, the new tight sash frame 4 is inserted into the opening 1 from the outside of the room, and the second tight members 13a to 13d attached to the indoor side surface of the shoji incorporating part 6 are partially shown in FIG. 4 (b). The outer side surface portions 15a to 15d of the spacers 3a to 3d and the outer side end surface of the corner tight material 23 are brought into contact with each other, and the upper and lower portions of the cover portion 5 are screwed and fixed to the spacer 3 at the indoor side portion.

As a result, the newly installed sash frame 4 is attached by so-called carry-out, in which the shoji mounting portion 6 is located on the outside of the existing sash frame 2, and is a spacer which is the indoor side surface of the shoji mounting portion 6 and the mounting portion on the existing sash frame 2 side. The connection part with the outdoor side surface of 3 is
The second tight members 13a to 13d and the corner tight member 23 completely block the inside and the outside of the room, and are sealed for four rounds.

Further, the tip of the first tight material 12 provided in the outer peripheral direction above and on the left and right outer peripheral portions of the shoji mounting portion 6 comes into contact with the inner peripheral surface 24 of the opening portion 1 and the second tight material. A space 25 is formed between them and communicates with the upper and left and right vertical directions. This space 25 is a space 25 ', 2 in the left and right vertical directions.
Since the lower end of 5'is open to the outside air communicating portion 25a formed between the lower frame 4b and the existing sash frame 2 ', the atmospheric pressure space communicates with the outside air through the outside air communicating portion 25a.

Further, the space 2 is provided in the shoji incorporating portion 6a of the upper frame 4a.
A groove 26 is formed between the first tight material 12 and the rising portion 9 of the indoor side edge along the upper side of the No. 5.

It should be noted that a new draining piece 2 which also serves as a cover is provided at a lower portion of the shoji incorporating portion 6b of the lower frame 4b at a distance from the draining portion of the old lower frame.
7 is attached to form an outside air communication passage 25a (shown by a broken line in FIG. 1) reaching the above-described isobaric space between the lower spacer portion 3b and the old lower frame.

Finally, the decorative cover 28 is attached to the indoor side by inserting it into the indoor side portion of the cover portion 5 of the new sash frame 4.

The d and the third tight materials 18a, 18c and 18d may be connected in series. In addition, the second,
Third tight material, corner tight member 23 and fourth
The tight material 20 is not limited to the shape of the embodiment.

With the above-described configuration, the remodeled window has a four-round frame portion in which the boundary portion between the new sash frame 4 and the existing sash frame 2 is surrounded by the tight members 13, 18, 20, and 23 so that the inside and the outside of the window are surrounded by the tight material 13, 18, 20, 23. Since it is shut off and airtightly connected, the cover portion 5 of the new sash frame 4 and the decorative cover 2
No outside air enters the space D between the spacer 8 and the spacer 3. Therefore,
The outside air does not leak into the room, and the third and fourth tight members (airtight members) 1 are provided between the spacer 3 and the existing sash frame 2.
Since they are airtightly connected to each other for four rounds by 8a, 18c, 18d and 20, outside air does not leak into the room even through the space C between the spacer 3 and the existing sash frame 2.

Further, the first tight material 12 first blocks most of the wind and rain sprayed on the frame portion, and prevents these from directly entering the inside of the frame portion. In the rainwater that has passed through the tight material 12, the space 25 formed between the tight material 12 and the second tight material 13 is at an atmospheric pressure equal to the outside air, so the left and right vertical spaces 25 are formed. After falling through ′ and 25 ′, they are smoothly discharged to the outside through the outside air communicating portion 25a on the lower frame 4b side. In this case, the rainwater is the shoji part 6
The space 25 is guided by the tight material 12 and the groove 26 formed by the rising portion 9. The rising portion 9 also prevents the invading rainwater from leaking into the frame portion, and the cover piece 14 provided on the upper edge of the rising portion 9 enhances its function, and
The rising part 9 prevents the tight material or the like provided on the indoor side from getting wet.

FIG. 5 shows another embodiment, which has the configuration of the above-described embodiment, and further has an isobaric space 25 between the first tight material 12 and the rising portion 9 in the shoji incorporating portion 6a. The drain holes 29, 29 'are formed so as to communicate with the inner peripheral side of the portion 6. The drain hole 29 'is opened to the outside of the closed indoor side shoji.

In the case of this embodiment, the rainwater accumulated in the groove 26 in the upper frame portion 6a of the shoji-incorporating portion 6 can be discharged more quickly, and the tight material on the indoor side is less likely to get wet.

In addition, the shoji incorporating portion 6 in the above-described embodiment corresponds to a general structure of the sash frame attached to the opening,
The water-draining structure based on the isobaric theory in the above-described embodiment concretely shows a reliable airtight structure between the inner peripheral surface of the opening and the general sash frame. In this case, the same is true even if the first tight material 12 is a sealing material.

That is, the disclosed embodiments include the following technical matters.

In the configuration in which the sash frame is attached to the opening, the sash frame is provided with an abutting portion for the building body, and a tight material interposed between the abutting portion and the skeleton forms an airtight band over four rounds, and The upper frame and the left and right vertical frames are fitted with a tight material that is closely adhered to the inner peripheral surface of the frame opening with a space more outside the airtight zone than the airtight zone, thereby forming a water drainage zone, and between the water drainage zone and the airtight zone. It is characterized in that a space continuous to the outer periphery of the upper frame portion and both left and right vertical frame portions is formed, and the space is communicated with the outside air through an outside air communication portion formed between the lower frame and the body. Window sealing structure.

As a result, even if rainwater intrudes into the space formed between the water drainage zone and the airtight zone, the space is in the state of equal pressure with the outside air, so the space in the vertical direction moves to the lower frame side. It falls and is discharged from the outside air communication unit to the outside.

The space between the drainage zone and the airtight zone is a drain hole provided in the upper frame of the sash frame, on the inner peripheral side of the sash frame, and on the outdoor side of the shoji screen, characterized in that it is communicated. The window sealing structure described in.

As a result, rainwater that has entered the space formed between the drainage strip and the airtight body is removed to the outside through the drain hole.

Effect of the Invention In a refurbished window with a new sash frame installed, airtightness is already assured when the new sash frame is installed. Regardless of whether the decorative cover on the interior side or the inner frame is attached or finished, the remodeled window The airtightness of is secured.
