It is also possible to directly fasten and fix the end portion in the vertical direction from the outside with a fastening fixing member 27 such as a screw.

In contrast to the above basic configuration, in this embodiment, the following configuration can be provided.

(1) As shown in FIG. 3 (to FIG. 5)
On the outer surface 3a of the horizontal frame member 3, a backing material 33 that comes into contact with the back surface 12a of the inner wall surface material 12 constituting the wall portion 6 is erected.
The inner wall surface member 12 is installed so that the end portion 12b directly abuts on the outer surface 3a of the horizontal frame member 3 or is close to the outer wall surface member 3 (the end portion 12b is close to the outer surface 3a of the horizontal frame member 3), and the back surface 12a is the back surface. In a state of being in contact with the material 33, the inner wall window crosspiece 21 constituting the wall portion 6 is fastened together with the back material 33.

Here, the outer surface 3a of the horizontal frame member 3 is a surface of the horizontal frame member 3 facing the outer peripheral side of the window frame 5. Specifically, the upper surface of the upper horizontal frame material 3 (upper frame material) and the lower surface of the lower horizontal frame material 3 (lower frame material) are the outer surface 3a of the horizontal frame material 3.

The inner wall surface material 12 is a gypsum board that is located above and below the window frame 5 and is cut to an appropriate size according to the opening 11 and attached. Specifically, the gypsum board installed on the upper side of the upper horizontal frame material 3 and the gypsum board installed on the lower side of the lower horizontal frame material 3 refer to the inner wall surface material 12 in this case.

The back surface 12a is a surface of the inner wall surface material 12 facing the outdoor side. The periphery of the end portion 12b of the surface on the outdoor side of the inner wall surface material 12 is the portion of the back surface 12a that comes into contact with the backing material 33.

The position of the back surface 12a is a reference position that defines the position of the back surface 12a of the inner wall surface material 12 in the inside / outside direction X when the inner wall surface material 12 is correctly installed on the wall portion 6.

By hitting the back surface 12a of the inner wall surface material 12, the back surface material 33 positions the inner wall surface material 12 in the inner / outer direction X, and serves as a receiving member for fixing the inner wall surface material 12. The backing member 33 is erected from the outer surface 3a of the horizontal frame member 3 toward the outside (upper or lower) so as to be substantially perpendicular to the outer surface 3a of the horizontal frame member 3. For the backing material 33, it is preferable to use plywood which is thinner and stronger than the inner wall surface material 12. The inner wall surface material 12 and the inner wall window crosspiece 21 are in contact with each other on both sides of the backing material 33. The backing material 33 is almost entirely covered by the end portion 12b of the inner wall surface material 12.

The end portion 12b is an end portion 12b on the horizontal frame member 3 side of the upper and lower end portions 12b of the inner wall surface material 12. Specifically, the end portion 12b is a lower end portion of the upper inner wall surface material 12 and an upper end portion of the lower inner wall surface material 12. The end portion 12b on the horizontal frame material 3 side of the inner wall surface material 12 extends toward the horizontal frame material 3 so as to cover the backing material 33, and is substantially horizontal to the outer surface 3a of the horizontal frame material 3. It becomes the edge.

When installed so as to directly abut against each other, the end portion 12b of the inner wall surface material 12 on the horizontal frame member 3 side directly contacts the outer surface 3a of the horizontal frame member 3 without any gap. It is to be (line contact).

When installed so as to be close to each other, the end portion 12b on the horizontal frame member 3 side of the inner wall surface member 12 has a slight gap with respect to the outer surface 3a of the horizontal frame member 3 in a state where there is no intervening object. And face each other. The slight gap is a gap that is not visually noticeable or has a size that can be filled later by a putty coating operation or the like.

The inner wall window cross rail 21 is a pair of upper and lower cross rails 18 forming the opening 11. When the window frame 5 is installed in the opening 11, the inner wall window crosspiece 21 is located above and below the window frame 5. The inner wall window crossbar 21 includes an inner wall window crosspiece 21 (inner wall upper window crossbar) located above the window frame 5, and an inner wall window crossbar 21 (inner wall lower window crossbar) located below the window frame 5. There is.

Co-tightening is to simultaneously fix the inner wall surface material 12 and the backing material 33 to the inner wall window crossbar 21 by using the same fastening fixing member 36 such as a screw. The fastening fixing member 36 is formed from the outside of the wall portion 6 (from the indoor side to the outdoor side) with respect to the inner wall surface material 12, the backing material 33, and the inner wall window horizontal bar 21 which are stacked in order in the inner / outer direction X direction. It can be installed almost horizontally.

(2) The outer surface 3a of the horizontal frame member 3 may be formed with a recess 42 into which the base end portion 33a of the backing member 33 is inserted.
The backing material 33 may be projected outward from the outer surface 3a of the horizontal frame material 3 with the base end portion 33a fitted in the recess 42.

Here, the base end portion 33a is an end portion of the back support material 33 on the horizontal frame material 3 side, and is a portion that becomes a root of the back support material 33 with respect to the horizontal frame material 3. Specifically, the base end portion 33a includes a lower end portion of the back support material 33 provided on the upper horizontal frame material 3 and an upper end portion of the back support material 33 provided under the lower horizontal frame material 3. Become.

The recess 42 can be a groove continuously formed on the outer surface 3a of the horizontal frame member 3 along the extending direction (left-right direction Y) of the horizontal frame member 3. The groove of the recess 42 is formed to have a constant width and a constant depth, which is substantially equal to the thickness 43 (dimension of the inner / outer direction X) of the backing material 33. The depth of the recess 42 is set to be about half or less of the thickness of the horizontal frame member 3 (dimension in the vertical direction Z). In order to form the recess 42, it is preferable to use a horizontal frame material 3 that is thicker than the existing one. The base end portion 33a of the backing material 33 is firmly inserted and fixed to the recess 42 without any gaps and without glaring.

As for the vertical frame member 4, as shown in FIG. 6, a similar recess 45 is formed on the outer surface 4a of the vertical frame member 4 (the surface facing the outer peripheral side of the window frame 5). Then, the base end portion 46a of the joint member 46 is fitted into the recess 45 so that the joint member 46 protrudes outward (in the left-right direction Y) from the outer surface 4a of the vertical frame member 4. The joint member 46 is formed to have substantially the same thickness as the inner wall surface material 12, and is abutted against the side surfaces of the inner wall surface material 12 installed on both sides of the window frame 5 in a substantially flush state.

The horizontal frame material 3 and the vertical frame material 4 are formed of, for example, a medium density fiberboard such as an MDF material. Medium density fiberboard is an artificial wood made from wood or plant fiber, and because of its high fiber density, it becomes a hard and sturdy member. A decorative sheet 49 is attached to the surface of the MDF material. For the joint member 46, a load-bearing surface material for construction is used.

(3) As shown in FIG. 3 (to FIG. 5)
The horizontal frame member 3 may be a strip member 51 having a rectangular cross section.
The end surface 3c on the indoor side of the horizontal frame member 3 as the strip member 51 having a rectangular cross section protrudes toward the indoor side from the inner wall surface material 12 (the surface on the indoor side) (projecting portion 52, FIG. 3). It may be exposed on the indoor side.

Here, the rectangular cross section is a rectangular cross-sectional shape having four sides of an outer surface 3a, an inner surface 3b, an indoor end surface 3c (inner end surface), and an outdoor end surface 3d (outer end surface). Is.

The outer side surface 3a and the inner side surface 3b are formed parallel to each other and having the same length. The indoor side end surface 3c and the outdoor side end surface 3d are formed to be parallel to each other and have the same length.

The inner side surface 3b is a surface of the horizontal frame member 3 facing the inner peripheral side of the window frame 5. Specifically, the lower surface of the upper horizontal frame member 3 and the upper surface of the lower horizontal frame member 3 are the inner side surface 3b of the horizontal frame member 3.

If necessary, the horizontal frame member 3 having a rectangular cross section may be provided with a chamfered portion 3e at a corner portion. The chamfered portion 3e is provided at a corner portion between the inner side surface 3b, the end surface 3c on the indoor side, and the end surface 3d on the outdoor side, for example.

The strip material 51 is an elongated strip-shaped plate. The horizontal frame member 3 as the strip member 51 is extended substantially horizontally in the left-right direction Y with the flat surface facing up and down. The horizontal frame material 3 has a certain width (dimension in the inner / outer direction X) and a constant thickness (dimension in the vertical direction Z), and extends to substantially the same length as the width of the window 2 (dimension in the left-right direction Y). Will be set up.

As for the vertical frame material 4, the vertical frame material 4 may be used as the strip member 51 in the same manner as the horizontal frame material 3. The vertical frame member 4 as the strip member 51 is extended in the vertical direction Z with the flat surface facing left and right. The vertical frame member 4 has a certain width (dimension in the inner / outer direction X) and a constant thickness (dimension in the left-right direction Y), and extends to substantially the same length as the height of the window 2 (dimension in the vertical direction Z). Will be set up.

The end surface 3c on the indoor side is a surface of the horizontal frame member 3 facing the indoor side. The end surface 3c on the indoor side is the decorative surface of the window frame 5. Similarly, the indoor end surface of the vertical frame member 4 is also the decorative surface of the window frame 5.

(4) As shown in FIG. 7,
In the inner wall window crosspiece 21, the width 63 of the wall portion 6 in the inner / outer direction X may be narrowed by the thickness 43 of the backing material 33.
The inner wall window crossbar 21 may be attached to the inner wall window vertical bar 22 constituting the wall portion 6 with a step portion 64 corresponding to the thickness 43 of the backing material 33 on the indoor side.

Here, the thickness 43 is the dimension of the backing material 33 in the inside / outside direction X. The width 63 is the dimension of the inner wall window crosspiece 21 in the inner / outer direction X.

The inner wall window vertical bar 22 is a vertical bar 19 located above and below the inner wall window cross bar 21 forming the opening 11 and supporting the inner wall window cross bar 21 in the vertical direction Z. The inner wall window vertical wooden bar 22 is appropriately installed on the upper side of the upper inner wall window crossbar 21 (inner wall upper window crossbar) and below the lower inner wall window crossbar 21 (inner wall lower window crossbar). The dimension of the inner wall window vertical wooden crosspiece 22 in the inner / outer direction X is substantially the same as the sum of the width 63 of the inner wall window crossbar 21 and the thickness 43 of the backing material 33.

The narrow width 63 means that the width 63 of the inner wall window crosspiece 21 is narrower by the thickness 43 of the backing material 33 as compared with the inner wall window vertical bar 22 or the existing inner wall window crosspiece 21A (FIG. 11). It is that.

The step portion 64 is formed on the indoor side by retracting the indoor side surface 21a of the inner wall window crossbar 21 to the outdoor side of the indoor side surface 22a of the inner wall window vertical wooden rail 22. The area between the outdoor side surface 21b of the inner wall window crossbar 21 and the outdoor side surface 22b of the inner wall window vertical wooden rail 22 (the circled portion A) is in a flush state.

<Action> The action of this example will be described below.

FIG. 8 is a diagram comparing the window structure of the present embodiment with the existing window structure (the left side is the present embodiment and the right side is the comparative example).

The existing window structure is as shown in the comparative examples of FIGS. 9 to 14 (mainly see FIG. 11). The existing window structure is as follows.

1) On the outer surface 3a of the horizontal frame member 3, a joint member 71 for connecting to the inner wall surface material 12 is erected at a position flush with the inner wall surface material 12 constituting the wall portion 6.
The inner wall surface member 12 and the joint member 71 are individually attached to the inner wall window crosspiece 21A in a state where the back surface 12a is in contact with the inner wall window crosspiece 21A constituting the wall portion 6, respectively. The joint member 46 has a thickness 72 that is substantially the same as that of the inner wall surface material 12.

As a result, the joint member 46 is interposed between the outer surface 3a of the horizontal frame member 3 and the inner wall surface member 12, so that the attachment structure of the horizontal frame member 3 to the wall portion 6 becomes complicated accordingly. Then, extra man-hours are required to install the joint member 46, and incidental work associated with the installation of the joint member 46 (for example, a seam peculiar to the window 2 is generated between the joint member 46 and the inner wall surface material 12). Since the putty coating work for this seam, the putty coating portion 13A, and FIG. 9) increase, the workability is poor.

Further, in order to individually attach the inner wall surface material 12 and the joint member 71 to the inner wall window crosspiece 21A, it is necessary to secure the mounting allowances for the inner wall window crosspiece 21A at two places on the upper and lower sides. The crossbar 21A has a large height dimension of 73A. That is, the height dimension 73A of the inner wall window crosspiece 21A is larger than the height dimension 73 of the inner wall window crosspiece 21 of this embodiment (height dimension 73A of the inner wall window crosspiece 21A> inner wall window. The height dimension of the crosspiece 21 is 73).

Then, by arranging the inner wall surface material 12 and the joint member 71 vertically and individually attaching them to the inner wall window crosspiece 21A, the attachment position of the inner wall surface material 12 and the joint member 71 to the inner wall window crosspiece 21A is set to the horizontal frame material. You will be away from 3. Therefore, it is necessary to install the inner wall window crossbar 21A away from the horizontal frame member 3 than the inner wall window crossbar 21 of this embodiment (separation distance 74A of the inner wall window crossbar 21> separation of the inner wall window crossbar 21). Distance 74).

2) A flange portion 81 projecting toward the outer surface 3a side (vertical direction Z) is integrally provided on the indoor end surface 3c of the horizontal frame member 3.
A pressing plate 82 is abutted and fixed to the flange portion 81 on the outer surface 3a of the horizontal frame member 3 with a gap of 72 minutes in the inner / outer direction X of the joint member 71.
The joint member 71 is projected outward from the outer surface 3a of the horizontal frame member 3 with the base end portion 71a sandwiched between the flange portion 81 and the pressing plate 82.

As a result, the horizontal frame member 3 becomes an L-shaped member 83. Then, a flange portion 81 and a pressing plate 82 are required for installing the joint member 71 on the outer surface 3a of the horizontal frame member 3, and the structure and member configuration for installing the joint member 71 become complicated.

As shown in FIG. 12, the window frame 5 directly abuts the left and right ends of the horizontal frame member 3 and the pressing plate 82 on the inside of the upper and lower ends of the vertical frame member 4 from the side, and the vertical frame member 4 The upper and lower ends and the left and right ends of the presser plate 82 are directly fastened and fixed laterally from the outside with a fastening fixing member 27 such as a screw so as to be assembled.

Further, as for the vertical frame material 4, as shown in FIG. 14, the vertical frame material 4 is provided with a flange portion 84 integrally provided at the end portion on the indoor side so as to project toward the outer surface side (left-right direction Y). It is a substantially L-shaped member 83.

3) The horizontal frame member 3 is a member (L-shaped member 83) having an L-shaped cross section having a flange portion 81 on the end surface 3c on the indoor side.
The horizontal frame member 3 is exposed to the indoor side in a state where the indoor side end surface 3c and the flange portion 81 are projected toward the indoor side from the joint member 71 and the inner wall surface material 12 (the indoor side surface).

As a result, the indoor end surface 3c and the flange portion 81 of the horizontal frame material 3 become the decorative surface of the window frame 5, so that the found dimension (dimension seen from the surface side) of the window frame 5 is increased by the amount of the flange portion 81. Become.

4) The inner wall window crossbar 21A is formed so that the width 63A of the inner wall window vertical bar 22 and the wall portion 6 in the inner / outer direction X are equally formed, and both the indoor side and the outdoor side are flush with each other.

As a result, the width 63A of the inner wall window crosspiece 21A in the inner / outer direction X is larger than the width 63 of the inner / outer direction X of the inner wall window crosspiece 21 of this embodiment (width 63A of the inner wall window crossbar 21A> inner wall window crossbar). The width of the crosspiece 21 63).

There is room for improvement in various parts of such an existing window structure.

<Effect> According to this embodiment, the following effects can be obtained.

(Effect 1) In the window structure, the backing material 33 is erected on the outer surface 3a of the horizontal frame material 3, and the end portion 12b of the inner wall surface material 12 is directly abutted against the outer surface 3a of the horizontal frame material 3. , The inner wall surface material 12 and the back support material 33 are placed in close contact with each other (close to the outer surface 3a of the horizontal frame material 3), and the inner wall surface material 12 and the back support material 33 are in contact with the back material 33. It may be fastened together with the window crossbar 21.

This simplifies the mounting structure of the horizontal frame material 3 to the wall portion 6, and since the inner wall surface material 12 is positioned in the inner / outer direction X by the backing material 33, the outer surface of the horizontal frame material 3 has been obtained so far. Since the joint member 71 (FIG. 11) that has been installed flush with the inner wall surface material 12 for position adjustment between the 3a and the inner wall surface material 12 is no longer required, the joint member 71 and the joint member 71 Reduction of members (pressing plate 82) required for installation, simplification of structure (flange portion 81), reduction of man-hours for installing joint member 71, incidental work associated with installation of joint member 71 (for example, joint member 71 and inner wall material) It is possible to reduce the putty coating work, the putty coating portion 13A, and FIG. 9) on the seam peculiar to the window 2 generated between the 12 and the window 2.

Further, since the joint member 71 is eliminated and the inner wall surface material 12 and the backing material 33 can be fixed (co-tightened) to the inner wall window cross bar 21 at one place, the inner wall window vertical bar 22 can be joined. Since it is not necessary to have mounting allowances for two places for mounting the member 71 and the inner wall surface member 12 individually, the height dimension 73 of the inner wall window vertical bar 22 can be reduced by that amount.

Moreover, by superimposing the inner wall surface material 12 and the backing material 33 and fastening them together to the inner wall window crosspiece 21, the attachment position of the inner wall surface material 12 and the backing material 33 to the inner wall window crosspiece 21 is set to the horizontal frame material. Since it can be brought closer to 3, the inner wall window crossbar 21 can be installed at a position closer to the horizontal frame member 3. By installing the inner wall window crossbar 21 closer to the horizontal frame material 3, it becomes possible to reliably drive the screw that fastens the inner wall material 12 and the backing material 33 into the inner wall window crossbar 21.

(Effect 2) In the window structure, a recess 42 is formed on the outer surface 3a of the horizontal frame material 3, and the backing material 33 is used on the outer surface 3a of the horizontal frame material 3 with the base end portion 33a fitted in the recess 42. It may be projected outward from. As a result, the backing material 33 can be directly installed on the outer surface 3a of the horizontal frame material 3, facilitating the installation of the backing material 33 and reducing the number of members required for installing the backing material 33. And so on. Then, by providing the backing member 33, it is possible to eliminate the joint member 71 that has been intervened and installed between the outer surface 3a of the horizontal frame member 3 and the inner wall surface member 12, as described above. The structure for installing (sandwiching and holding) the joint member 71, the member (pressing plate 82) and the shape (flange portion 81) used for installing the joint member 71 and the joint member 71 are eliminated, and the member configuration is simplified. You can do things like that.

(Effect 3) In the window structure, the horizontal frame material 3 is used as a strip member 51 having a rectangular cross section, and the indoor end surface 3c of the horizontal frame material 3 protrudes indoor from the inner wall surface material 12 (indoor side surface). It may be exposed in a state. As a result, the flange portion 81 disappears from the end surface 3c exposed on the indoor side of the horizontal frame material 3, and the end surface 3c itself without the flange portion 81 becomes the decorative surface of the window frame 5, so that the size of the window frame 5 is found. You can get slimming. Further, since the thickness of the horizontal frame material 3 (dimension in the vertical direction Z) can be increased within a range not exceeding the dimension of the flange portion 81 while slimming the found dimension of the window frame 5, the horizontal frame material can be increased. 3 The overall strength can be increased.

(Effect 4) In the window structure, the width 63 of the inner wall window vertical wooden crosspiece 22 may be narrowed, and a step portion 64 on the indoor side may be provided between the inner wall window vertical wooden crosspiece 22 and the inner wall window crossbar 21. As a result, the inner wall window crosspiece 21 can be miniaturized, and the backing material 33 can be accommodated and held in the step portion 64 with the inner wall window crosspiece 21. Even when the backing material 33 is provided on the outer surface 3a of the horizontal frame material 3, the backing material 33 can be housed in the wall portion 6 so that the backing material 33 does not get in the way.
