Hereinafter, a method and structure for mounting a sash frame according to the present invention will be described based on embodiments shown in the drawings.

An embodiment of a sash frame mounting structure (hereinafter referred to as mounting structure) illustrated in FIGS. This attachment structure is employed when the sash frame 7 is attached to the rectangular opening frame portion 3 formed at the attachment position on the second floor or higher of the detached house 1 . In addition, the mounting position on the second floor or higher means that the upper end surface of the opening frame portion 3 is at a height of, for example, 4 m or more from the ground. This attachment structure is specifically used when the sash frame 7 is attached to an inner balcony or a so-called sunroom that is surrounded by the roof 1a and the wall surface 2 and is not exposed to the outside.

The sash frame 7 is fitted inside the opening frame portion 3 . A fixing plate 10 is used to attach the sash frame 7 to the opening frame portion 3 . The fixing plate 10 is installed between one side frame 4 and one vertical frame 8 and between the other side frame 4 and the other vertical frame 8, respectively. A glass window portion 17 is attached to the sash frame 7 . In this embodiment, a pair of left and right glass window portions 17 are attached to the sash frame 7 so as to be slidable to the left and right. Since the glass window portion 17 is separate from the sash frame 7, it is not an essential component of the present invention. The arrow L in the drawing indicates the longitudinal direction of the fixed plate 10 (flat portion 11), and the arrow W indicates the width direction of the fixed plate 10 (flat portion 11).

As illustrated in FIG. 5 , this mounting structure has an opening frame portion 3 that is rectangular in front view, a sash frame 7 that is rectangular in front view, and a fixing plate 10 . The opening frame portion 3 has a pair of left and right side frames 4, an upper surface frame 5, and a lower surface frame 6, and has a rectangular shape when viewed from the front. Various known specifications for forming the periphery of the opening formed in the wall surface 2 can be used for the opening frame 3 . Therefore, the opening frame portion 3 is made of aluminum, resin, wood, or a composite material of a plurality of these types, as required.

The sash frame 7 has a pair of left and right vertical frames 8 and a pair of upper and lower horizontal frames 9, and has a rectangular shape when viewed from the front. As the sash frame 7, various known specifications can be used. Therefore, the sash frame 7 is made of aluminum, resin, wood, or a composite material of a plurality of these types, as required. The sash frame 7 is formed with through holes 7a for screws for fixing the sash frame 7 to the opening frame portion 3 at appropriate positions.

As illustrated in FIGS. 6 to 8 , each fixing plate 10 includes a rectangular plate-shaped flat portion 11 and an engagement member protruding in the thickness direction of the flat portion 11 at one end in the width direction W of the flat portion 11 . It has a stop portion 12 , a sealing material 14 and a sealing piece 15 . More specifically, the locking portion 12 protrudes toward the surface 11a of the flat portion 11 and extends in the longitudinal direction L. As shown in FIG. The locking portion 12 and the flat portion 11 are integrated and made of a rigid material such as metal (aluminum, aluminum alloy, carbon steel, etc.) or hard resin.

In this embodiment, the locking portion 12 protrudes perpendicularly to the planar portion 11 in a cross-sectional view. The locking portion 12 has a mounting groove 13 extending in the longitudinal direction L and having a T-shaped cross section. Locking portion 12 and mounting groove 13 extend over the entire length of flat portion 11 . As long as the seal piece 15 can be attached to the locking portion 12, the mounting groove 13 is not necessary if the seal piece 15, the locking portion 12, and the seal piece 15 are joined with an adhesive or the like.

The sealing material 14 is attached to the rear surface 11b of each fixing plate 10 . The sealing material 14 is formed of a known compressible vulcanized rubber (butyl rubber, silicone rubber, etc.) or a soft material such as an elastomer, and may be a foam containing internal cells or a solid material containing no internal cells. The sealing material 14 has watertightness to block moisture in a non-compressed state or a compressed state. Sealing material 14 extends over the entire length of flat portion 11 .

The width (dimension in the width direction W) of the sealing material 14 is, for example, 10% or more of the dimension in the width direction W of the flat portion 11, and the thickness is, for example, about 2 mm or more and 20 mm or less. In this embodiment, one band-shaped sealing member 14 extends, but for example, a plurality of sealing members 14 may be arranged at intervals in the width direction W, or may be arranged substantially on the back surface 11b. A sealing material 14 that covers the entire area can also be used.

A seal piece 15 that protrudes in the other width direction W and extends in the longitudinal direction L is attached to the engaging portion 12 . The seal piece 15 is made of a known compressible vulcanized rubber (butyl rubber, silicone rubber, etc.) or a soft material such as an elastomer. The sealing piece 15 may be made of a foam containing air bubbles, but is preferably a solid body containing no air bubbles. The seal piece 15 has watertightness to block moisture in an uncompressed state or a compressed state. The seal piece 15 extends over the entire length of the flat portion 11 .

In this embodiment, a seal piece 15 having a T-shaped cross section is detachably attached to the mounting groove 13 and is fitted and mounted in the mounting groove 13 . More specifically, as illustrated in FIG. 9A, the seal piece 15 has a flat base end portion 15a and a band-like fin portion 15b orthogonal to the base end portion 15a. The fin portion 15b protrudes toward the other side in the width direction W and is tapered at the protruding distal end side. The projection length h of the fin portion 15b from the locking portion 12 is appropriately set, and is, for example, about 5 mm to 20 mm, preferably about 6 mm or more and 15 mm or less. The thickness of the fin portion 15b is, for example, about 1 mm to 3 mm.

Various shapes can be adopted for the seal piece 15, and the seal piece 15 illustrated in FIG. 9B can be used. The seal piece 15 has an H-shaped cross section, and the tip of the fin portion 15b is flat. This seal piece 15 is also detachably attached to the mounting groove 13 and is fitted into the mounting groove 13 for mounting. It is also possible to simply employ the strip-shaped fin portion 15b extending in the longitudinal direction L and join it to the engaging portion 12 with an adhesive or the like.

The height of the side frame 4 of the opening frame portion 3 (the inner dimension of the opening height of the opening frame portion 3) and the full length of the fixing plate 10 are substantially the same. In addition, since the sash frame 7 has a size that fits into the opening frame portion 3 just enough, the height of the sash frame 7 (total length of each vertical frame 8) is equal to that of the side frames 4 of the opening frame portion 3. It is slightly smaller than the height (the inner dimension of the opening height of the opening frame portion 3). Therefore, the height of the side frame 4 of the opening frame 3 (inner dimension of the opening height of the opening frame 3), the total length of the fixing plate 10, and the height of the sash frame 7 (the total length of each vertical frame 8) are approximately the same size.

As illustrated in FIGS. 1 to 4, in this mounting structure, each fixing plate 10 is fixed to each opposing side frame 4 . The rear surface 11 b of each fixing plate 10 faces the surfaces of the left and right side frames 4 of the opening frame portion 3 . The locking portion 12 of each fixing plate 10 is arranged on the outdoor side of the surface of the side frame 4 to which the fixing plate 10 is fixed, and extends vertically.

Then, as illustrated in FIG. 4 , the sealing material 14 is compressed between the back surface 11 b of each fixing plate 10 and the front surface of each side frame 4 . Each fixing plate 10 and each side frame 4 are watertightly joined by a sealing material 14 compressed between them.

Moreover, as illustrated in FIG. 4, the outdoor side ends 8a of the respective vertical frames 8 of the sash frame 7 fitted inside the opening frame portion 3 and the engaging portions 12 of the respective fixing plates 10 are connected with each other. The sealing piece 15 (fin portion 15b) is sandwiched. In this embodiment, each fin portion 15b is sandwiched between the outdoor end 8a and the locking portion 12, so that the fixing plate 10 having the locking portion 12 is bent toward the surface 11a side. there is By sandwiching the seal pieces 15 (fins 15b) between the vertical frames 8 and the fixed plates 10, the sandwiched seal pieces 15 (fins 15b) are watertight. are spliced.

Since this mounting structure is constructed using the sash frame mounting method of the present invention, an example of the procedure of this mounting method will be described below.

As illustrated in FIG. 10, each fixing plate 10 to which the sealing member 14 and the sealing piece 15 are attached in advance is fixed to the surface of each corresponding side frame 4 by indoor work. More specifically, the rear surface 11b of each fixing plate 10 faces the surface of the side frame 4 of the opening frame portion 3 formed on the wall surface 2, and the locking portion 12 of each fixing plate 10 The fixing plate 10 is arranged on the outdoor side of the opposing side frames 4 to extend vertically.

After the fixing plate 10 is set at a predetermined position with respect to the side frame 4 in this way, the screws 16 are inserted into the through holes 10a to fix the respective fixing plates 10 to the respective side frames 4 with the screws 16. As shown in FIG. As a result, the seal material 14 is compressed between the back surface 11b and the side frame 4, and the back surface 11b of each fixing plate 10 and each side frame 4 are watertightly joined by the seal material 14. be done. Inside the opening of the opening frame portion 3, the locking portion 12 (seal piece 15) protrudes on the outdoor side and extends vertically.

Next, as illustrated in FIGS. 11 and 12, the sash frame 7 is inserted into the opening frame portion 3 from the indoor side. Since the engaging portion 12 protrudes inside the opening of the opening frame portion 3, when the sash frame 7 is inserted into the opening frame portion 3 from the indoor side, the outdoor side ends 8a of the respective vertical frames 8 will be It abuts on the seal piece 15 (fin portion 15b) from the tip side. The fin portion 15b is elastically deformed and gradually bent by being pressed by the abutted outdoor end 8a.

When the sash frame 7 is further inserted to the outdoor side, as illustrated in FIG. 4, the respective locking portions 12 are locked to the outdoor side ends 8a of the respective vertical frames 8 with the sealing pieces 15 interposed therebetween. The fins 15b are sandwiched between the engaging portions 12 and the outdoor end 8a. That is, each locking portion 12 functions as a stopper, and the sash frame 7 is arranged at an appropriate insertion depth with respect to the opening frame portion 3 .

After setting the sash frame 7 to an appropriate insertion depth with respect to the opening frame portion 3 in this way, the screws 16 are inserted into the through holes 7a. As a result, each seal piece 15 is sandwiched between the outdoor end 8a of each vertical frame 8 and the locking portion 12 of each fixing plate 10, and each of the vertical frames 8 facing each other is provided. The sash frame 7 is fixed to the opening frame portion 3 by connecting with the fixing plate 10 . Each vertical frame 8 and each locking portion 12 are watertightly joined by a sealing piece 15 (fin portion 15b) interposed therebetween. As a result, the mounting structure illustrated in FIGS. 1-4 is constructed. The pair of glass window portions 17 are attached to the sash frame 7 after the sash frame 7 is attached to the opening frame portion 3 .

According to the present invention, as described above, the work of fixing each fixing plate 10 to the surface of each side frame 4 can be easily performed from the indoor side. Further, the operation of inserting and fixing the sash frame 7 into the opening frame portion 3 can be easily performed from the indoor side. Then, between one side frame 4 and one vertical frame 8, and between the other side frame 4 and the other vertical frame 8, can be watertightly joined by the sealing material 14 and the sealing piece 15. .

In the construction of the detached house 1, unlike the construction of a building or the like, large-scale equipment cannot be used, so that the work at high places largely depends on human power. According to this embodiment, the sash frame 7 can be attached to the opening frame portion 3 while ensuring sealing performance by the work on the indoor side. Therefore, even if the opening frame part 3 is located at a high place above the second floor of the detached house 1, unstable work on scaffolding or ladders outdoors can be eliminated. It is also possible to omit the work of separately filling sealants from the outside between one side frame 4 and one vertical frame 8 and between the other side frame 4 and the other vertical frame 8. become. In this way, heavy labor at unstable heights can be avoided, which is advantageous for greatly reducing the labor of work.

Even an unskilled operator can attach the sash frame 7 to the opening frame 3 as prescribed, which is very useful for those skilled in the art. Furthermore, the sash frame 7 can be attached to the opening frame portion 3 by a single person, and the attachment work can be carried out regardless of the weather because the work is done indoors. This point is also a great advantage for those skilled in the art.

Between the upper surface frame 5 of the opening frame part 3 and the upper end surface of the sash frame 7 (upper surface of the upper horizontal frame 9), and between the lower surface frame 6 and the lower end surface of the sash frame 7 (lower surface of the lower horizontal frame 9) Each of the spaces between them is located at a position set back to the indoor side from the eaves of the roof 1a, and each gap between them extends in the horizontal direction, so it is impossible to strictly ensure watertightness. Not required. However, as illustrated in FIG. 11, a sealing material 14a similar to the sealing material 14 is also provided on the upper end surface of the sash frame 7 (the upper surface of the upper horizontal frame 9) and the lower end surface (the lower surface of the lower horizontal frame 9). should extend over the entire length of the horizontal frame 9 and attached. As a result, the sealing material 14a is interposed between the upper surface frame 5 and the upper end surface of the sash frame 7 and between the lower surface frame 6 and the lower end surface of the sash frame 7 in a compressed state. As a result, the upper surface of the upper surface frame 5 and the upper surface of the sash frame 7 and the lower surface of the lower surface frame 6 and the lower surface of the sash frame 7 can be watertightly joined by the intervening sealing material 14a.

In the seal piece 15 illustrated in FIG. 4, the fin portion 15b is bent toward the surface 11a of the fixing plate 10 of the locking portion 12 sandwiching the fin portion 15b. No direct exposure to UV rays. Therefore, it is advantageous to maintain the seal piece 15 soundly for a long period of time.

As illustrated in FIG. 13, each seal piece 15 (fin portion 15b) is sandwiched between the outdoor end 8a of the vertical frame 8 and the locking portion 12 of the fixed plate 10, and the surface 11a of the fixed plate 10 is It can also be in a bent state toward the side opposite to the side. In this seal piece 15, a fin portion 15b extends from between the outdoor end 8a and the engaging portion 12 to the outside. Therefore, rainwater or the like is prevented from entering the gap between the outdoor end 8a and the locking portion 12. As shown in FIG. As a result, it is advantageous for preventing corrosion of the fixing plate 10 and the sash frame 7 and for suppressing raindrop marks from adhering to the lower wall surface 2 .

In addition, in the seal piece 15 illustrated in FIG. 9A, the fin portion 15b sandwiched between the outdoor end 8a and the locking portion 12 is bent in the direction illustrated in FIG. 4, as illustrated in FIG. I'm not sure if it bends in any direction. Therefore, the fins 15b are bent with respect to the proximal end 15a so that the fins 15 are reliably bent in one of the bending directions of the fins 15b illustrated in FIGS. 4 and 13 . should be inclined in advance in one of the desired directions in a cross-sectional view.

When the seal piece 15 illustrated in FIG. 9B is used, the fin portion 15b is simply sandwiched between the outdoor end 8a and the engaging portion 12 and is compressed, and is not bent. Therefore, there is an advantage that the load on the seal piece 15 (fin portion 15b) can be reduced. On the other hand, with this seal piece 15, the adjustment of the depth of insertion of the sash frame 7 into the opening frame portion 3 is within the range of the amount of compressive deformation of the fin portion 15b, so the adjustment allowance is small. In addition, due to some distortion of the opening frame portion 3 and the sash frame 7, when the sash frame 7 is inserted into the opening frame portion 3, the left and right vertical frames 8 (outdoor side ends 8a) face each other. In some cases, the gaps between the engaging portion 12 and the engaging portion 12 may not be even on the left and right. In this case, it may be difficult to ensure the sealing performance by the seal piece 15 between the vertical frame 8 (outdoor end 8a) and the engaging portion 12 on either one of the left and right sides.

When the seal piece 15 illustrated in FIG. 9A is used, the depth of insertion of the sash frame 7 into the opening frame 3 can be adjusted within the range of the sum of the amount of bending deformation and the amount of compressive deformation of the fin portion 15b. Therefore, there is an advantage that the adjustment allowance can be increased. In addition, even if the gaps between the left and right vertical frames 8 (outdoor-side ends 8a) and the engaging portions 12 facing the vertical frames 8 are not equal on the left and right, the tips of the fins 15b are in contact with the outdoor-side ends 8a. If pressed to some extent, the sealing performance between the vertical frame 8 (outdoor end 8a) and the engaging portion 12 can be ensured. Therefore, even if the opening frame portion 3 and the sash frame 7 are somewhat distorted, it is advantageous for ensuring sealing performance. Further, even if the opening frame portion 3 and the sash frame 7 are slightly distorted due to an earthquake or the like after the sash frame 7 is attached to the opening frame portion 3, the seal piece 15 (fin portion 15b) is elastically deformed. As a result, there is also the advantage that the sealing performance between the vertical frame 8 (outdoor end 8a) and the engaging portion 12 can be maintained.

In this embodiment, the base end portion 15a of the seal piece 15 slides in the longitudinal direction L with respect to the mounting groove 13 so as to be detachable. Therefore, depending on the specifications of the sash frame 7 to be attached, an appropriate seal piece 15 capable of ensuring sufficient sealing performance between the sash frame 7 (outdoor end 8a) and the locking portion 12 is attached to the locking portion 12. can be used. That is, according to the specifications of the sash frame 7, the desired range of the projection length h from the engaging portion 12 is selected and used so as to ensure sufficient sealing performance. A desired range of the protruding length h in which sufficient sealing performance can be ensured is grasped in advance by a preliminary test or the like.

The present invention can also be applied to the case where the sash frame 7 is attached to the opening frame portion 3 formed at the attachment position below the second floor of the detached house 1 . In this case, it is possible to attach the sash frame 7 to the opening frame portion 3 while securing the sealing property by performing the work on the indoor side in the same manner as in the above-described embodiment, although the work at a high place is not required.
