JP-A-2019-65503

In Patent Document 1, when manufacturing a wall surface unit, fittings are built in the skeleton opening frame, and screws are screwed from the inner peripheral surface of the frame of the fitting toward the skeleton opening frame from a prospective direction.
Therefore, when fixing the FIX window of the finished product to the skeleton opening frame with screws, the glass is removed from the window frame, the window frame is built in the skeleton opening frame, and the screws are screwed from the inner peripheral surface of the window frame. After fixing the window frame to the skeleton opening frame, it is necessary to reattach the glass to the window frame.
In addition, when fixing the hinged window of the finished product to the skeleton opening frame with screws, the hinged window is built in the skeleton opening frame, and the sliding door is opened while supporting the hinged window so that it does not tilt due to the weight of the shoji. It is necessary to expose the inner peripheral surface and screw a screw from this inner peripheral surface to fix the window frame to the skeleton opening frame.
Therefore, there is a problem that the work man-hours for mounting the frame body of the fitting in the frame opening frame increases, and the work time also increases.

An object of the present invention is to provide a frame mounting structure and a wall surface unit capable of reducing the work man-hours for mounting the frame of the fitting to the frame opening frame.

The frame mounting structure of the present invention is a frame mounting structure for mounting a frame of fittings to a skeleton opening frame, wherein the frame is arranged on the inner peripheral side of the skeleton opening frame, and the skeleton opening frame The frame is attached to the skeleton opening frame by a screw screwed in the finding direction from the outer peripheral surface.
The wall surface unit of the present invention is a wall surface unit including a skeleton opening frame and fittings mounted in the skeleton opening frame, and the frame body of the fitting is arranged on the inner peripheral side of the skeleton opening frame, and the skeleton The frame is attached to the skeleton opening frame by a screw screwed in the finding direction from the outer peripheral surface of the opening frame.

According to the present invention, it is possible to provide a frame body mounting structure and a wall surface unit that can reduce the work man-hours for mounting the frame body of the fitting to the frame opening frame.

It is a vertical cross-sectional view of the wall surface unit constructed by applying the mounting structure of the frame body which is the embodiment of this invention. It is a cross-sectional view of the wall surface unit shown in FIG. It is an inside view of the wall surface unit shown in FIG. It is an inside view which shows the deformation example of a wall surface unit.

Hereinafter, a preferred embodiment of the frame mounting structure and the wall surface unit according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are a vertical sectional view and a horizontal sectional view of a wall surface unit 1 to which the frame mounting structure according to the embodiment of the present invention is applied.
FIG. 3 is an internal view of the wall surface unit 1, and only the upper spacer 45, the vertical spacer 46, and the screw S portion, which will be described later, are displayed as a cross section. Further, the cross member 34 below the window sill 33, which will be described later, is also omitted.
The wall surface unit 1 illustrated here is treated as a single structure when attached to a building, and includes a fitting 2 and a skeleton opening frame 3.

The fitting 2 has a shoji screen 20 supported inside the frame body 10. In the present embodiment, as the fitting 2, an inward opening window configured so that the shoji 20 is opened to the indoor side by a hinge H interposed between the frame body 10 and the shoji 20 is illustrated. The frame body 10 is formed by framing the upper frame 11, the lower frame 12, and the left and right vertical frames 13 in four directions.
In the present embodiment, frame materials having the same cross-sectional shape are applied as the upper frame 11, the lower frame 12, and the left and right vertical frames 13. The frame materials constituting the upper frame 11, the lower frame 12, and the left and right vertical frames 13 are extruded shaped materials made of synthetic resin, and as shown in the lower frame 12 of FIG. 1, the frame main body having a substantially rectangular hollow shape. The portion W1 and the door stop portion W2 protruding from the inner peripheral portion located on the outdoor side of the frame main body portion W1 to the inner peripheral side are integrally formed. A sealing material W3 that seals between the door stop portion W2 and the shoji 20 is provided at a portion facing the room at the protruding edge portion. A recess W4 is provided along the longitudinal direction on the outer peripheral side of the frame main body W1 along the prospective direction. The recess W4 is provided at a portion substantially central to the prospective direction, and constitutes an engaging ridge W5 extending along the longitudinal direction of the frame material on the outdoor side and the indoor side, respectively.
A metal reinforcing material 15 is inserted into the hollow portion of the frame main body portion W1 of the upper frame 11, the lower frame 12, and the left and right vertical frames 13. The reinforcing material 15 is made of aluminum alloy, steel, or the like, and is inserted over the entire length of the upper frame 11, the lower frame 12, and the left and right vertical frames 13 to reinforce the frame body 10. As the upper frame 11, the lower frame 12, and the left and right vertical frames 13, extruded metal members such as an aluminum alloy may be used. In this case, the reinforcing material 15 can be eliminated.
In the frame main body portion W1, the hollow portion into which the reinforcing material 15 is inserted and the prospective surface portion W6 for partitioning the concave portion W4 form a surface on the skeleton opening frame 3 side in the hollow portion.
The reinforcing material 15 is formed in a hollow rectangular frame shape. Then, in the reinforcing material 15, the screw receiving surface portion 151 into which the screw S is screwed is arranged along the prospective surface portion W6 of the frame main body portion W1.
The screw receiving surface portion 151 is formed so as to cover substantially the entire surface of the prospective surface portion W6 exposed to the hollow portion. That is, the dimension of the screw receiving surface portion 151 in the prospective direction is about the same as the dimension of the hollow portion in the prospective direction. Further, the reinforcing member 15 is arranged over substantially the entire length of the frame main body portion W1 in the longitudinal direction, and the dimension of the screw receiving surface portion 151 in the longitudinal direction is about the same as the dimension of the hollow portion in the longitudinal direction.

Here, in the present embodiment, the direction along the depth of the fitting 2 indicated by the arrow A in FIGS. 1 and 2 is set as the prospective direction. A plane along the prospective direction may be referred to as a prospective plane. Further, the direction indicated by the arrow B in FIGS. 1 and 2 is set as the finding direction. The finding direction is the vertical direction orthogonal to the prospective direction in the case of a member that is elongated along the left-right direction of the fitting 2 such as the upper frame 11 and the lower frame 12, and the fitting 2 is like the vertical frame 13. In the case of a member that is elongated along the vertical direction of, the horizontal direction is orthogonal to the prospective direction. A plane along the finding direction may be referred to as a finding surface.

As shown in FIGS. 1 to 3, the shoji 20 is configured to have an upper stile 22, a lower stile 23, and left and right vertical stiles 24 mounted on four circumferences of a rectangular face member 21. The upper stile 22, the lower stile 23, and the left and right vertical stiles 24 are extruded profiles made of synthetic resin.
In the fitting 2 of the present embodiment, a hinge H is provided between the vertical frame 24 and the vertical frame 13 located on the left side when viewed from the indoor side, so that the shoji 20 opens to the indoor side around the hinge shaft along the upper and lower sides. It is an inward hinged window configured in. The vertical stile 24 located on the right side when viewed from the indoor side is provided with a handle 25 on the finding surface facing the indoor side.
Reference numeral 26 in the drawing is a ridge that sandwiches the face material 21 between the stiles 22, 23, and 24, respectively. Further, in the present embodiment, the upper stile 22, the lower stile 23, and the left and right vertical stiles 24 constituting the shoji 20 are made of stile materials having the same cross-sectional shape.

The skeleton opening frame 3 includes left and right vertical members 31, a lintel 32 which is an upper member connecting the upper ends of the vertical members 31, and a window base 33 which is a lower member connecting the lower ends of the vertical members 31. It is configured in the shape of a rectangular frame. In the skeleton opening frame 3 of the present embodiment, the vertical member 31 extends below the window sill 33, and the horizontal member 34 is attached between the lower ends of the vertical member 31.
Depending on the relationship between the height dimension of the wall surface unit 1 and the height dimension of the fitting 2, the vertical member 31 is extended above the lintel 32, and a horizontal member is placed above the lintel 32 through a gap. The skeleton opening frame 3 may be arranged by arranging the skeleton opening frame 3, or the skeleton opening frame 3 may be formed only by the vertical member 31, the lintel 32, and the window sill 33 without providing the horizontal member. Further, a heat insulating material may be arranged in the gap between the lintel 32 or the window sill 33 and the cross member 34, if necessary. The vertical member 31, the lintel 32, the window sill 33, and the horizontal member 34, respectively, are structural members, and are made of, for example, wood.
A surface material 40 is attached to the finding surface of the vertical member 31 and the forage 32 facing the outside. Further, the surface material 40 is also attached to the finding surface facing the outside from the window sill 33 to the cross member 34.

The window sill 33 has an engaging protrusion 331 that engages with the recess W4 of the lower frame 12, and has a shape on which the lower frame 12 can be placed. When the engaging protrusion 331 engages with the recess W4, the engaging protrusion W5 of the lower frame 12 comes into contact with the outdoor surface and the indoor surface of the engaging protrusion 331, thereby moving in the prospective direction of the lower frame 12. Movement is restricted. Therefore, in the lower frame 12, the recess W4 engages with the engaging protrusion 331 of the window sill 33 and is positioned in the prospective direction with respect to the window sill 33.
A waterproof sheet 41 is arranged between the window base 33 and the lower frame 12. The waterproof sheet 41 is arranged so as to cover the window base 33 and the outdoor surface of the surface material 40 from the upper surface of the engaging protrusion 331.
In the window sill 33, a sealing material 43 having airtightness and watertightness is disposed between the upper surface on the indoor side of the engaging protrusion 331 and the lower surface of the lower frame 12. The sealing material 43 is a band-shaped member formed in advance, and is arranged over the entire length of the window sill 33 in the longitudinal direction. When the fitting 2 is placed on the window sill 33, the sealing material 43 is crushed by the lower frame 12 to seal between the lower frame 12 and the window sill 33.

A spacer is interposed between the upper frame 11 and the left and right vertical frames 13, and the forage 32 and the vertical member 31. That is, the upper spacer 45 is arranged between the upper frame 11 and the forage 32, and the vertical spacer 46 is arranged between the vertical frame 13 and the vertical member 31.
The upper spacer 45 is composed of two spacers, a first spacer 451 and a second spacer 452. The first spacer 451 is sized to fit in the recess W4 of the upper frame 11, and the upper surface of the first spacer 451 is flush with the upper surface of the upper frame 11.
The second spacer 452 is arranged between the upper surface of the upper frame 11 and the first spacer 451 and the lower surface of the forage 32. The estimated size of the second spacer 452 is larger than that of the first spacer 451. Therefore, the second spacer 452 is arranged in a range from the outdoor edge of the upper frame 11 to the indoor edge of the first spacer 451. Further, the thickness dimension (height dimension in the vertical direction) of the second spacer 452 is larger than the depth dimension of the recess W4. As will be described later, in the state where the second spacer 452 is not attached, the height dimension of the opening in which the fitting 2 of the skeleton opening frame 3 is arranged is the height dimension of the frame body 10 to which the second spacer 452 is not attached. It is configured so that the frame body 10 can be attached to the skeleton opening frame 3 in a Kendon style.
The upper spacer 45 is arranged over the entire length excluding the clearance region C1 set from the left and right ends of the upper frame 11 toward the left and right centers of the upper frame 11. The length dimension of the clearance region C1 is set in consideration of the expansion and contraction of the upper frame 11 made of synthetic resin, and is, for example, 100 mm.

The vertical spacer 46 has an engaging protrusion 461 that engages with the recess W4 of the vertical frame 13, and is arranged in a range from the outdoor edge of the vertical frame 13 to the indoor edge of the recess W4.
The vertical spacer 46 is arranged over the entire length excluding the clearance region C2 set from the upper and lower ends of the vertical frame 13 toward the upper and lower centers of the vertical frame 13. The length dimension of the clearance region C2 is set in consideration of the expansion and contraction of the vertical frame 13 made of synthetic resin. The length of the clearance region C2 may be, for example, the same dimension as the clearance region C1, and when the length dimension of the vertical frame 13 is longer than the length dimension of the upper frame 11, the dimension is longer than the clearance region C1. For example, it may be 150 mm.
These clearance areas C1 and C2 are spaces provided to reduce the influence of expansion and contraction of the upper frame 11 and the vertical frame 13 made of synthetic resin. For example, when the upper frame 11 and the vertical frame 13 are thermally stretched, the ends of the upper frame 11 and the vertical frame 13 are joined to each other, so that the heat elongation cannot be absorbed, and the upper frame 11 and the vertical frame 13 are joined. The corner portion to be formed is curved and protrudes toward the skeleton opening frame 3. Therefore, when the upper spacer 45 and the vertical spacer 46 are arranged over the entire length of the upper frame 11 and the vertical frame 13, stress is applied to the upper frame 11 and the vertical frame 13 because there is no space for the corner portion to escape. In addition, cracks may occur.
On the other hand, if the clearance areas C1 and C2 are set and the spacers 45 and 46 are arranged over the entire length excluding the clearance areas C1 and C2, the upper frame 11 and the vertical frame 13 are thermally stretched when the upper frame 11 and the vertical frame 13 are thermally stretched. Since a space is secured for the corner portion to which the vertical frame 13 is joined to escape, it is possible to prevent the upper frame 11 and the vertical frame 13 from being cracked or the like. Therefore, the clearance areas C1 and C2 are gap spaces provided to prevent the upper frame 11 and the vertical frame 13 from being damaged when the synthetic resin upper frame 11 and the vertical frame 13 expand and contract. Therefore, the minimum value of the length dimension of the clearance regions C1 and C2 is set according to the amount of deformation such that the upper frame 11 and the vertical frame 13 are thermally stretched and curved. Further, since the screw S cannot be screwed into the clearance areas C1 and C2 where the spacers 45 and 46 are not arranged, the maximum value of the length dimension of the clearance areas C1 and C2 is set at the edge of each of the frames 11 and 13. It is set according to the screwing position of the nearest screw S. The actual length dimensions of the clearance areas C1 and C2 are set within the range from the minimum value to the maximum value.

On the indoor side of the upper spacer 45 and the vertical spacer 46, an airtight and watertight sealing material 44 is arranged between the upper frame 11 and the forage 32 and between the vertical frame 13 and the vertical member 31. It is set up. As the sealing material 44, a foam sealing material having a larger thickness than the sealing material 43 can be used.

[Wall unit assembly process]
Next, the process of assembling the wall surface unit 1 will be described.
Assemble the fitting 2 at the fitting 2 manufacturing factory. Since this assembly method is the same as that of the general fitting 2, the description thereof will be omitted.
At the assembly plant of the skeleton opening frame 3, the skeleton opening frame 3 is assembled by framing the left and right vertical members 31, the lintel 32, the window sill 33, and the horizontal members 34.

Next, in the assembly factory of the wall surface unit 1, the fitting 2 is attached to the skeleton opening frame 3 to assemble the wall surface unit 1. The wall surface unit 1 may be assembled at the same factory as the fitting 2 manufacturing factory and the skeleton opening frame 3 assembly factory, or at another factory.
In order to form the wall surface unit 1 by attaching the frame body 10 of the fitting 2 to the skeleton opening frame 3, first, from the upper surface of the window sill 33, that is, the inner peripheral surface (expected surface) of the skeleton opening frame 3, to the surface material 40. The waterproof sheet 41 is arranged over the window base 33, and the sealing material 43 is further arranged on the upper surface of the window sill 33 on the indoor side of the engaging protrusion 331.

The waterproof sheet 41 is a sheet material having water shielding and flexibility, and is arranged so as to continuously cover the outdoor surface of the window sill 33 and the surface material 40 from the upper surface of the engaging protrusion 331.
Next, the first spacer 451 is arranged in the recess W4 of the upper frame 11, the engaging protrusion 461 is arranged in the recess W4 of the vertical frame 13, and the vertical spacer 46 is attached to the vertical frame 13.
Then, the fitting 2 is built in the skeleton opening frame 3 by the Kendon method. That is, the fitting 2 is lifted with the second spacer 452 not attached, and the upper frame 11 is brought closer to the lintel 32. As a result, the engaging protrusion W5 of the lower frame 12 can get over the engaging protrusion 331 of the window base 33. Then, the fitting 2 is moved in the prospective direction while being lifted upward. At this time, the vertical frame 13 slides while the vertical spacer 46 is in contact with the inner peripheral surface of the vertical member 31.
Next, the fitting 2 is moved downward from the state where the recess W4 of the lower frame 12 is located above the engaging protrusion 331. As a result, the recess W4 of the lower frame 12 engages with the engaging protrusion 331, and the sealing material 43 is sandwiched between the lower frame 12 and the window sill 33 and pressure-welded.
After that, the second spacer 452 is inserted into the gap between the upper frame 11 and the forage 32 and arranged.

Next, the screw S is screwed from the outer peripheral surfaces of the vertical member 31 and the forage 32. The screw S is a tapping screw and can be screwed in using an electric screwdriver or the like. The screw S screwed into the vertical member 31 is screwed from the vertical member 31 to the reinforcing member 15 of the vertical frame 13 via the vertical spacer 46 and the vertical frame 13. The screw S screwed into the forage 32 is screwed from the forage 32 to the reinforcing material 15 of the upper frame 11 via the second spacer 452 and the first spacer 451 of the upper spacer 45 and the upper frame 11. By fixing with these screws S, the upper frame 11 and the vertical frame 13 are fixed to the forage 32 and the vertical member 31.
The outer peripheral surface of the vertical member 31 into which the screw S is screwed, the inner peripheral surface of the vertical member 31, the outer surface of the vertical spacer 46 in contact with the vertical member 31, and the inner surface of the vertical spacer 46 in contact with the prospective surface portion W6 of the recess W4. The prospective surface portion W6 of the vertical frame 13 and the screw receiving surface portion 151 of the reinforcing member 15 arranged along the prospective surface portion W6 are formed along the prospective direction of the fitting 2 and are formed as planes parallel to each other. Therefore, when the screw S is screwed in the direction orthogonal to the outer peripheral surface of the vertical member 31, that is, in the finding direction, the screw S is formed on each surface of the vertical member 31 and the vertical spacer 46 along the prospective direction, and the prospective surface portion W6 of the vertical frame 13. Then, the reinforcing material 15 is screwed in from a direction orthogonal to the screw receiving surface portion 151, and the screwing operation of the screw S can be smoothly performed, and the screw fixing can be easily performed.
The screw S screwed from the gusset 32 is the gusset 32, the first spacer 451 and the second spacer 452 of the upper spacer 45, the prospective surface portion W6 of the upper frame 11, and the screw receiving surface portion 151 of the reinforcing material 15 in the prospective direction parallel to each other. Since the screw is screwed in from the direction (vertical direction) orthogonal to the plane (horizontal plane) along the above, the screwing operation of the screw S can be smoothly performed and the screw fixing can be easily performed.
Further, since the screw receiving surface portion 151 into which the screw S is screwed is formed so as to cover almost the entire surface of the prospective surface portion W6 exposed to the hollow portion, even if the screwing position of the screw S is slightly displaced, it is fixed by the screw S. Can be reliably performed, and screw fixing can be easily performed.
Further, regarding the lower frame 12, although the screw S is not screwed between the lower frame 12 and the window sill 33, the concave portion W4 engages with the engaging protrusion 331 to limit the movement in the prospective direction. It is immovably attached to the window sill 33.

Next, the sealing material 44 is arranged in the gap opened on the indoor side of the upper frame 11 and the vertical member 31 and the gap opened on the indoor side of the vertical frame 13 and the forage 32. The wall surface unit 1 is completed by the above assembly work. The method of attaching the wall surface unit 1 to a building such as a house may be performed in the same manner as in Patent Document 1, and thus the description thereof will be omitted.

According to the present embodiment, since the frame body 10 of the fitting 2 is attached by screwing the screw S from the outer peripheral surface of the skeleton opening frame 3 in the finding direction, the shoji 20 is opened when the screw S is screwed in, and the fitting 2 is opened. It is not necessary to support it so that it does not tilt, and the work man-hours for attaching the frame body 10 of the fitting 2 to the frame opening frame 3 can be reduced, and the work time can also be shortened.
Further, since the screw S is screwed from the outer peripheral surface of the skeleton opening frame 3, a sufficient working space can be secured and the workability can be improved. For example, when the screws S are screwed from the outer peripheral surface of the skeleton opening frame 3, the left and right vertical members 31 and the vertical frame 13 can be fixed by the screws S at the same time by a plurality of workers, and one wall surface unit 1 is completed. The work time until it is made can be shortened.

Since the upper spacer 45 and the vertical spacer 46 are arranged over almost the entire length of the upper frame 11 and the vertical frame 13, the construction workability can be improved as compared with the case where a plurality of piece-shaped spacers are used. That is, when a piece-shaped spacer is used, it is necessary to align the screwing position of the screw S with the arrangement position of the spacer before screwing the screw S, which complicates the work. On the other hand, in the present embodiment, since the upper spacer 45 and the vertical spacer 46 are arranged over the entire length excluding the clearance regions C1 and C2, it is not necessary to perform the alignment and the workability can be improved.
Further, since the upper spacer 45 and the vertical spacer 46 are arranged in the regions other than the clearance regions C1 and C2 on the corner side of the frame body 10, the frame body 10 made of synthetic resin expands and contracts due to a temperature change or the like, and corners. Even if the portion protrudes toward the skeleton opening frame 3, the spacers 45 and 46 are not arranged in the portion, so that a space for the upper frame 11 and the vertical frame 13 to escape when the upper frame 11 and the vertical frame 13 are thermally stretched can be secured. Therefore, when the upper frame 11 and the vertical frame 13 are thermally stretched, the escape spaces are eliminated by the spacers 45 and 46, and stress is applied to the upper frame 11 and the vertical frame 13 to prevent cracks and the like.

Since the screw S is screwed from the frame opening frame 3 to the reinforcing material 15 in the frame 10, the load applied to the fitting 2 can be transmitted to the frame opening frame 3, and the mounting strength of the fitting 2 and the frame opening frame 3 can be improved. ..
Further, since the spacers 45 and 46 are engaged with the recesses W4 of the upper frame 11 and the vertical frame 13, the spacers 45 and 46 are engaged in addition to being fixed by the screws S, so that the upper frame 11 and the vertical frame 13 are engaged with each other. Movement in the prospect direction can be more regulated.
Further, it is necessary to fix the lower frame 12 to the window sill 33 by using screws S by engaging the recess W4 of the lower frame 12 with the engaging protrusion 331 of the window sill 33 to restrict the movement in the prospective direction. Since there is no screw S, the screwing work can be reduced, and since there is no screw S penetrating the lower frame 12 or the window sill 33, the waterproof sheet 41 is not formed with a through hole, and the waterproof performance can be improved.

The present invention is not limited to the configuration described in the above embodiments, and modifications within the range in which the object of the present invention can be achieved are included in the present invention.
For example, as a spacer arranged between the frame body 10 and the skeleton opening frame 3, a piece-shaped upper spacer 455 and a vertical spacer 465 may be used as shown in FIG. Even when the piece-shaped upper spacer 455 and the vertical spacer 465 are used, it is preferable to arrange the spacers 455 and 465 in the regions other than the clearance regions C1 and C2.
Further, the frame body 10 and the shoji 20 of the fitting 2 are not limited to those made of synthetic resin, and may be made of an extruded profile made of metal such as aluminum.

The fitting 2 is not limited to the inward opening window, and various fittings such as a FIX window, an outward opening window, and a raising and lowering window can be used. In the case of the FIX window, the frame material that holds the glass is directly fixed to the frame opening frame 3, so that the frame material becomes the frame body.
Further, the fitting 2 of the above-described embodiment is an internal window in which the fitting 2 is arranged within the expected dimensions of the skeleton opening frame 3, but a part of the fitting 2 in the expected direction is arranged outside the skeleton opening frame 3. Semi-external fittings may be used. In the case of a semi-external fitting, a nail fin that protrudes in the finding direction is generally provided. Therefore, the nail fin is brought into contact with the outdoor surface of the skeleton opening frame 3 and the screw S is attached to the outer peripheral surface of the skeleton opening frame 3. It may be fixed by screwing in the direction of finding. At this time, a screw may be screwed into the nail fin to fix the fitting to the skeleton opening frame 3, or the nail fin is not fixed to the skeleton opening frame 3 and the fitting is fixed to the skeleton opening frame 3 only with the screw S. You may.

In the above embodiment, the lower frame 12 and the window sill 33 are not fixed by the screws S, but the lower frame 12 and the window sill 33 may also be fixed by the screws S. That is, the upper frame 11, the lower frame 12, and the vertical frame 13 may be fixed to the vertical member 31, the lintel 32, and the window sill 33 with screws S.
In the above embodiment, the spacer is arranged between the frame opening frame 3 and the frame body 10, but for example, the vertical frame 13 may be directly attached to the vertical member 31 without providing the spacer.
The reinforcing member 15 arranged in the hollow portion of the frame main body portion W1 is not limited to the configuration of the embodiment. For example, as the reinforcing material, a plate-shaped reinforcing material arranged along the prospective surface portion W6 may be used, or a reinforcing material having a convex cross section may be used. The reinforcing material may have at least a screw receiving surface portion 151 along the prospective surface portion W6.

[Summary of Invention]
The frame mounting structure of the present invention is a frame mounting structure for mounting a frame of fittings to a skeleton opening frame, wherein the frame is arranged on the inner peripheral side of the skeleton opening frame, and the skeleton opening frame The frame is attached to the skeleton opening frame by a screw screwed in the finding direction from the outer peripheral surface.
According to the present invention, since the frame of the fitting is attached by screwing the screw from the outer peripheral surface of the opening frame of the skeleton in the finding direction, the man-hours for attaching the frame of the fitting to the opening frame of the skeleton can be reduced and the working time is also reduced. Can be shortened. For example, when the fitting is a FIX window, it is not necessary to remove the glass from the window frame or reattach it as in the conventional case, so that the work man-hours can be reduced. Similarly, when the fitting is a hinged window or the like, it is not necessary to open the shoji, so that it is not necessary to screw the fitting while supporting it so that it does not tilt, and the work man-hours can be reduced.

In the frame mounting structure of the present invention, the frame is configured to include an upper frame, a lower frame, and left and right vertical frames, and the skeleton opening frame includes an upper member, a lower member, and left and right vertical members. The upper frame and the left and right vertical frames are fixed to the upper member and the left and right vertical members by the screws screwed from the upper member and the left and right vertical members, and the lower frame is fixed to the upper member and the left and right vertical members. It is preferable that the lower material is engaged with and positioned in the prospective direction with respect to the lower material.
According to the present invention, the upper frame and the left and right vertical frames of the frame body are fixed to the upper material and the vertical material of the skeleton opening frame by screws, but the lower frame is engaged with the lower material without using screws. Therefore, the screwing work of the screw is reduced, and since there is no screw penetrating the lower frame or the lower material, the waterproof performance can be easily improved.

In the frame mounting structure of the present invention, the frame is configured to include an upper frame, a lower frame, and left and right vertical frames, and the skeleton opening frame includes an upper member, a lower member, and left and right vertical members. The upper frame, the lower frame, and the left and right vertical frames are fixed to the upper member, the lower member, and the left and right vertical members by the screws screwed from the upper member, the lower member, and the left and right vertical members. Is preferable.
According to the present invention, the upper frame, the lower frame, and the left and right vertical frames of the frame body are fixed to the upper material, the lower material, and the vertical material of the skeleton opening frame by screws. It is not necessary to process the required engaging structure such as recesses and protrusions, and the skeleton opening frame can be made into a simple structure.

In the frame mounting structure of the present invention, a spacer that regulates the vertical and horizontal movement of the frame is provided between the upper frame and the left and right vertical frames and the upper member and the left and right vertical members. It is preferable that the screws are screwed from the upper member and the left and right vertical members into the upper frame and the left and right vertical frames via the spacer.
According to the present invention, since the spacer is arranged between the frame body of the fitting and the skeleton opening frame, the spacer can be brought into close contact with the outer peripheral surface of the frame body and the inner peripheral surface of the skeleton opening frame, and the screw can be screwed. It is possible to prevent the frame from being deformed when screwed.

In the frame mounting structure of the present invention, the spacer is arranged between the upper spacer arranged between the upper frame and the upper member, and between the left and right vertical frames and the left and right vertical members. The upper spacer is provided with three spacers, that is, the left and right vertical spacers, and the upper spacers are arranged over the entire length excluding the clearance area set from the left and right ends of the upper frame toward the left and right centers of the upper frame. Is preferably arranged over the entire length excluding the clearance region set from the upper and lower ends of the vertical frame toward the upper and lower centers of the vertical frame.
According to the present invention, since it is only necessary to prepare three spacers, the upper spacer and the left and right vertical spacers, the construction work becomes easy. For example, when a large number of piece-shaped spacers are prepared according to each screw position, it is necessary to place the piece-shaped spacers at a predetermined position between the frame of the fitting and the frame opening frame of the fitting and screw the screws according to the positions. Therefore, the construction work becomes complicated. On the other hand, according to the present invention, since the spacers that are continuous in a predetermined range are provided, the construction work becomes easy.
Further, since each spacer is arranged in a region other than the clearance region provided on the corner side of the frame body, the influence of expansion and contraction of the frame body made of synthetic resin can be reduced.

In the frame mounting structure of the present invention, the upper frame, the lower frame, and the left and right vertical frames are made of an extruded material made of synthetic resin having a hollow portion, and are fixed to the skeleton opening frame by the screws. A metal reinforcing material is arranged in the hollow portion of the extruded material, and the metal reinforcing material has a screw receiving surface portion arranged at least in the hollow portion along the prospective surface portion on the skeleton opening frame side. However, it is preferable that the screws are screwed from the outer peripheral surface of the skeleton opening frame into the screw receiving surface portion of the reinforcing material.
According to the present invention, since the frame of the fitting is made of an extruded material made of synthetic resin, the heat insulating performance of the fitting can be easily improved as compared with the case where a metal frame such as aluminum is used.
Further, since the screws are screwed into the metal reinforcing material, the frame body can be securely fixed to the frame opening frame even if a frame body made of synthetic resin is used.
Further, since the screw receiving surface portion is arranged along the prospective surface portion, it is possible to easily realize that the screw receiving surface portion is arranged over the entire length of the prospective surface portion. Therefore, even if the screwing position of the screw S is slightly deviated, the frame opening frame and the frame body can be reliably fixed.

The wall surface unit of the present invention is a wall surface unit including a skeleton opening frame and fittings mounted in the skeleton opening frame, and the frame body of the fitting is arranged on the inner peripheral side of the skeleton opening frame, and the skeleton The frame is attached to the skeleton opening frame by a screw screwed in the finding direction from the outer peripheral surface of the opening frame.
According to the present invention, since the frame of the fitting is attached by screwing the screw from the outer peripheral surface of the opening frame of the skeleton in the finding direction, the man-hours for attaching the frame of the fitting to the opening frame of the skeleton can be reduced and the working time is also reduced. Can be shortened.
