Description

  The present invention relates to a frame material for constituting an additional frame to be attached for an inner window, for example, when a window is made into a double window at the time of home renovation.

  Conventionally, a window is sometimes made into a double window from the viewpoint of a soundproofing effect and a heat insulating effect. In particular, when renovating a house, when providing an inner window on the indoor side of an existing window (outer window) to form a double window, for example, as described in Patent Documents 1 and 2, An additional frame for the inner window is newly provided on the indoor side of the existing frame, and a method of inserting an inner window material made of a glass plate and a sash frame into the additional frame is employed.

For example, as shown in FIG. 10A, the additional frame is constructed by attaching a long horizontal frame material fs and a vertical frame material fv to a frame not shown in the figure. Such a horizontal frame material fs and a vertical frame material fv are usually composed of a base material attached to an existing frame and a cosmetic cover material fitted to the base material. The cover material is made of, for example, an extruded product of resin.
Further, when the horizontal frame material fs and the vertical frame material fv are formed in a frame shape, as shown in the drawing, both ends in the longitudinal direction of the horizontal frame material fs are in contact with the two vertical frame materials fv. It is often framed with a so-called “vertical winning” joint structure. At this time, as shown in FIG. 10B, it is preferable in terms of appearance that the front end face v1 of the vertical frame member fv and the front end face s1 of the horizontal frame member fs are finished to be flush with each other.
Japanese Utility Model Publication No. 63-24220 JP 2007-297831 A

However, in order to actually finish these front end faces v1 and s1, it is necessary to make fine adjustments at the construction site strictly, and it takes time and effort.
Further, even if such a laborious work is performed, the front end faces v1 and s1 are not always flush with each other depending on the technique of the installer, and as a result, the appearance of the additional frame becomes poor. There was a case.

Therefore, as shown in FIG. 11, the depth d1 of the vertical frame material fv and the depth d2 of the horizontal frame material fs are set to different lengths, and after construction, the front end face v1 of the vertical frame material fv and the horizontal frame material are set. A method is also conceivable in which a step is formed with the front end surface s1 of fs so that they are not flush with each other. In the case of this illustrated example, the depth d1 of the vertical frame material fv is made several mm larger than the depth d2 of the horizontal frame material fs, and after construction, the front end face v1 of the vertical frame material fv is the front end of the horizontal frame material fs. It protrudes forward (inside the room) by that much from the surface s1.
Thus, if the specification is such that a step is formed between the front end face v1 of the vertical frame member fv and the front end face s1 of the horizontal frame member fs, the front end faces v1 and s1 are flush with each other as shown in FIG. There is no need to make fine adjustments at the construction site as much as Therefore, an additional frame having an excellent appearance can be configured without laborious work, which is very preferable in terms of workability.

However, when the vertical frame material fv and the horizontal frame material fs having different depths are manufactured in this way, the base material of the vertical frame material fv and the base material of the horizontal frame material fs are formed by different extrusion molds. It is necessary to form the cover material of the vertical frame material fv and the cover material of the horizontal frame material fs with different extrusion molds, which is disadvantageous in terms of production cost.
In addition, since the base frame material and the cover material cannot be used for both the vertical frame material fv and the horizontal frame material fs, a base material and a cover material for the vertical frame material fv and a base material and a cover material for the horizontal frame material fs are required. It was necessary to arrange the required number in advance, and the construction preparation was troublesome.

  An object of the present invention is to provide an additional frame having a specification in which a step is formed between the front end surface of the vertical frame material and the front end surface of the horizontal frame material, for example, by making the depth of the vertical frame material different from the depth of the horizontal frame material. Because it can be constructed at multiple different depths when it is configured, it can be used with both vertical frame material and horizontal frame material, reducing the production cost and complexity of construction preparation, and excellent in appearance Is to provide.

The frame material of the present invention is a long frame material comprising a base material attached to an existing frame and a cover material fitted to the base material, and constituting an additional frame,
The base material includes a support plate that comes into contact with the existing frame, a base material inner plate extending from one end of the support plate in the short direction, and the other end of the short direction in the same direction as the base material inner plate. It consists of an extended base material skin,
A plurality of inner plate grooves along the longitudinal direction are formed on the outer surface of the base material inner plate,
On the outer surface of the base material outer plate, outer plate concave grooves along the same number of longitudinal directions as the inner plate concave grooves are formed,
The cover material is the same as the front plate disposed opposite to the support plate, a cover material inner plate extending from one end of the front plate in the short direction, and the cover material inner plate from the other end in the short direction. Consisting of a cover material skin extending in the direction,
On the inner surface of the cover material inner plate, an inner plate ridge that fits into the plurality of inner plate grooves is formed,
On the inner surface of the cover material outer plate, a plurality of outer plate ridges are formed to fit into the plurality of outer plate grooves,
One of the outer plate concave grooves is formed at a proximal end portion of the base material outer plate in the short direction, and one of the outer plate protrusions is a distal end of the cover material outer plate in the short direction. Formed in the part,
The outer plate ridges are formed so as to be separable so that the outer plate ridges other than the outer plate ridges formed at the tip part are located at the tip part.
It is preferable that a notch groove is formed between the outer plate ridges and can be separated.

  According to the frame material of the present invention, for example, the depth of the vertical frame material is different from the depth of the horizontal frame material, and a step is formed between the front end surface of the vertical frame material and the front end surface of the horizontal frame material. When constructing an additional frame, etc., it can be installed at multiple different depths, so it can be used with both vertical frame material and horizontal frame material, reducing production costs and construction preparation complexity, and also in appearance Excellent.

Hereinafter, the frame material of the present invention will be described in detail with reference to the drawings.
FIG. 1 and FIG. 2 show an example of the frame material 10 of the present invention. This frame material 10 has an existing window, that is, an inner window provided on the indoor side of an outer window at the time of renovation of a house. When a double window is used, it is used as a vertical frame material and a horizontal frame material for constituting an additional frame for the inner window.
FIG. 3 is a schematic perspective view showing an example of an additional frame F constructed using the frame material 10, and FIG. 4 shows a state in which the rail member L is laid on the horizontal frame material Fs of the additional frame F. It is a longitudinal cross-sectional view which shows a mode that the inner window material W was engage | inserted by the expansion frame F. FIG.
The extension frame F in this example is formed in a frame shape with a so-called “vertical winning” joint structure in which both ends in the longitudinal direction of the two horizontal frame members Fs are in contact with the two vertical frame members Fv, respectively. At the same time, the depth D1 of the vertical frame member Fv is made larger than the depth D2 of the horizontal frame member Fs, and the front end surface of the vertical frame member Fv is more forward than the front end surface of the horizontal frame member Fs by ΔD (= D1-D2). It is finished so as to protrude to the indoor side. In this example, ΔD is about 3.2 mm.

The frame material 10 is made of a long extruded body of aluminum, and is made of a base material 20 attached to the indoor side end of the existing existing frame B and a long extruded body of vinyl chloride resin. And a cover material 30 for makeup fitted to the base material 20.
The base material 20 includes a support plate 21 whose mounting surface 21b abuts on the indoor side end surface of the existing frame B, a base material inner plate 22 extending from one end of the support plate 21 in the short direction, and other short sides. It consists of a base material outer plate 23 extending from the end.
Screw holes 21a are formed in the support plate 21 along the longitudinal direction, and the base material 20 is attached to the existing frame B by screwing using the screw holes 21a.
The base material inner plate 22 is located on the side where the inner window material W is fitted, that is, on the inner peripheral side when the rectangular frame-shaped extension frame F as shown in the illustrated example is constructed, and contacts the inner window material W. Or the rail member L for the inner window material W is laid. On the other hand, the base material outer plate 23 is a portion located on the outer peripheral side.

  Both the base material inner plate 22 and the base material outer plate 23 have base end portions 22a and 23a as ends in the short direction of the support plate 21, and are substantially perpendicular to the support plate 21 from the base end portions 22a and 23a. In the same direction. In this example, the extension length L1 from the base end portion 22a of the base material inner plate 22 is formed to be larger than the extension length L2 from the base end portion 23a of the base material outer plate 23, and the base material The inner plate 22 extends longer than the base material outer plate 23. In addition, the front end portion 22b of the base material inner plate 22 in the short direction is easily slidably fitted into inner plate concave grooves 24 and 25 of the base material so that inner plate ridges 34 of the cover material 30 to be described later are fitted. A bent portion is formed by bending toward the base material outer plate 23 side.

On the outer surface of the base material inner plate 22, a plurality of inner plate concave grooves (in this example, the first inner plate concave groove in the longitudinal direction at a portion A 1 on the side of the distal end portion 22 b in the short direction of the base material inner plate 22. Two grooves 24 and a second inner plate concave groove 25 are formed substantially parallel to each other. These inner plate grooves 24 and 25 are for fitting inner plate ridges 34 of the cover material 30 to be described later when the cover material 30 is fitted to the base material 20, and the groove depth direction thereof. Is formed so as to be substantially perpendicular to the base material inner plate 22 (so as to be substantially parallel to the mounting surface 21b of the support plate 21). Furthermore, the outer surface of the base material inner plate 22 is formed to be lower by a portion indicated by t1 in the drawing at the portion A1 on the distal end portion 22b side in the lateral direction than the portion A2 on the proximal end portion 22a side, and is provided with a step. ing. This t1 corresponds to the thickness of the cover member 30 and is about 1.5 mm in this example.
Further, the portion A2 on the outer surface of the base material inner plate 22 is notched so that other members are not easily slipped when other members are fixed to this portion, and a large number of fine grooves along the longitudinal direction are formed. Is formed.

On the outer surface of the base material outer plate 23, the same number of outer plate grooves as the above-described inner plate grooves 24 and 25 (in this example, two of the first outer plate groove 26 and the second outer plate groove 27). Are formed substantially parallel to each other along the longitudinal direction. These outer plate concave grooves 26 and 27 are used to fit outer plate ridges 35 and 36 of the cover material 30 described later when the cover material 30 is fitted to the base material 20.
One of the two outer plate concave grooves 26, 27, that is, the first outer plate concave groove 26 is formed in the proximal end portion 23 a of the base material outer plate 23 in the short direction. Further, it is formed in a tapered shape that gradually separates from the mounting surface 21b of the support plate 21 from the groove upper part toward the groove bottom part so that the groove depth direction is not substantially perpendicular to the base material outer plate 23 but oblique. Yes. The other outer plate concave groove, that is, the second outer plate concave groove 27, is closer to the distal end portion 23 b side of the base material outer plate 23 than the first outer plate concave groove 26 in the first outer plate concave groove 26. It is formed in a tapered shape at the same angle as the groove 26.

  In addition, screw holes 22c and 23c are formed in the inner surface of the base material inner plate 22 and the inner surface of the base material outer plate 23, respectively, along the longitudinal direction. By using these screw holes 22c and 23c, the frame material 10 For example, a cap member C as shown in FIG. 5 can be screwed to both ends in the longitudinal direction. When constructing the frame material 10 by “vertical winning”, in particular, the cap member C is fitted to the lower end portion in the longitudinal direction of the vertical frame material Fv, and then fixed by screwing to cover the vertical frame material Fv. The material 30 can be supported so as not to slide off from the base material 20.

The cover member 30 extends from the front plate 31 disposed opposite to the support plate 21 of the base member 20, the cover member inner plate 32 extending from one end in the short direction of the front plate 31, and the other end in the short direction. It consists of a cover material outer plate 33.
The cover member inner plate 32 is located on the inner peripheral side together with the base member inner plate 22 when the rectangular frame-shaped extension frame F as shown in the illustrated example is constructed, or the cover member inner plate 32 is a rail. This is the part where the member L is laid. On the other hand, the cover material outer plate 33 is a portion located on the outer peripheral side together with the base material outer plate 23.

The cover material inner plate 32 and the cover material outer plate 33 both have base end portions 32 a and 33 a as ends in the short direction of the front plate 31, and are substantially perpendicular to the front plate 31 from the base end portions 32 a and 33 a. , Extending in the same direction. Further, the extending length L4 from the base end portion 33a of the cover material outer plate 33 corresponds to the depth D1 of the vertical frame material Fv after the construction shown in FIG. 3, and from the base end portion 32a of the cover material inner plate 32. Is formed to be larger than the extended length L3.
Further, the extension length L4 of the cover material outer plate 33 is formed to be larger than the extension length L1 of the base material inner plate 22.

  In this example, one inner plate protrusion 34 along the longitudinal direction is formed on the inner surface of the cover material inner plate 32 at the distal end portion 32 b in the short direction of the cover material inner plate 32. When the 30 is fitted, the inner plate ridge 34 is fitted to one of the inner plate grooves 24 and 25 of the base material inner plate 22. Specifically, the front end portion 32b of the cover member inner plate 32 is bent substantially perpendicularly to the cover member outer plate 33 side so as to fit into the inner plate grooves 24 and 25, and the inner plate protrusion 34 is formed. Is formed.

On the inner surface of the cover material outer plate 33, the same number of outer plate ridges as the outer plate grooves 26 and 27 formed in the base material outer plate 23 (in this example, the first outer plate ridge 35 and the second outer plate ridges). When the cover member 30 is fitted to the base member 20, these outer plate protrusions 35 and 36 are formed on the outer plate of the base member 20. It fits into the concave grooves 26, 27.
One of the two outer plate ridges 35, 36, that is, the first outer plate ridge 35 is formed at the distal end portion 33 b of the cover material outer plate 33 in the short direction. Specifically, the front end portion 33b of the cover material outer plate 33 in the short direction is fitted into the outer plate grooves 26 and 27 at an acute angle along the tapered shape of the outer plate grooves 26 and 27. It is bent and formed on the plate 32 side. The other outer plate ridge, that is, the second outer plate ridge 36, is closer to the proximal end portion 33 a side of the cover material outer plate 33 in the short direction than the first outer plate ridge 35. It is formed in a tapered shape at the same angle as the ridge 35.

And these outer-plate convex stripes 35 and 36 are formed so that isolation | separation is possible. In this example, a notch groove 37 along the longitudinal direction is formed between the first outer plate ridge 35 and the second outer plate ridge 36, and it is bent along the notch groove 37 or cut with a cutter or the like. The first outer plate ridge 35 can be easily separated. When the first outer plate ridge 35 is cut off in this way, the second outer plate ridge 36 is newly positioned at the distal end portion 33 b of the cover material outer plate 33 in the short direction.
Here, the length L5 from the base end portion 33a of the cover material outer plate 33 to the separation position (notch groove 37) corresponds to the depth D2 of the lateral frame material Fs after construction shown in FIG. The length L6 from the front end 33b of the cover material outer plate 33 to the separation position (notch groove 37) is the difference (ΔD) between the depth D1 of the vertical frame material Fv and the depth D2 of the horizontal frame material Fs after construction. It corresponds to.

When constructing the extension frame F as shown in FIG. 3 using such a frame material 10, first, the base material 20 is cut into a predetermined length, and the base material for the vertical frame material and the horizontal frame. Two material base materials are prepared, and the cover material 30 is similarly cut into a predetermined length to prepare two vertical frame material cover materials and two horizontal frame material cover materials.
Next, as shown in FIG. 6, two vertical frame base members 20 v and two horizontal frame base members 20 s are attached to the indoor side end face of an existing frame not shown in FIG. 6 by screws. At this time, the mounting surface 21b of the base material 20 is in contact with the indoor side end surface of the existing frame, the base material inner plate 22 is positioned on the inner peripheral side, and the base material outer plate 23 is positioned on the outer peripheral side. To place. Further, in this example, since the frame is formed with a “vertical winning” joint structure, the two longitudinal frame member base members 20v in which both ends in the longitudinal direction of the base member for horizontal frame member 20s are arranged in parallel are respectively provided. Arrange so that they abut.

Next, as shown in FIG. 7, two vertical frame material cover materials 30v are fitted into the vertical frame material base material 20v attached in this way, and the vertical frame material Fv is constructed.
In this case, specifically, as shown in FIG. 1C, the inner plate protrusion 34 is fitted into the second inner plate groove 25, and the first outer plate protrusion 35 is the first outer plate recess. The vertical frame material cover material 30v is fitted into the vertical frame material base material 20v so as to be fitted into the groove 26, and so that the second outer plate ridge 36 is fitted into the second outer plate groove 27.

Thereafter, the horizontal frame material Fs is constructed. Prior to that, first, as shown in FIG. 8A, in the horizontal frame material cover material 30s, the first outer plate projection 35 is formed along the notch groove 37. Separate.
Then, the first outer plate ridge 35 is cut off in this way, and the second outer plate ridge 36 is positioned at the distal end portion 33b of the cover material outer plate 33 in the short direction, and then shown in FIG. Thus, the cover material 30s for the horizontal picture frame material is fitted so that the inner plate ridge 34 is fitted in the first inner plate groove 24 and the second outer plate ridge 36 is fitted in the first outer plate groove 26. Is fitted into the base material 20s for the horizontal picture frame material.

When constructed in this way, the depth D1 of the vertical frame material Fv is formed to be equal to the extension length L4 of the cover material outer plate 33. On the other hand, the depth D2 of the horizontal picture frame material Fs is not equal to the extension length L4 of the cover material outer plate 33, but is equal to the length L5 from the base end portion 33a of the cover material outer plate 33 to the notch groove 37.
As a result, as shown in the example, the front end surface of the vertical frame member Fv protrudes inward from the front end surface of the horizontal frame member Fs by the difference between the extension length L4 and the length L5 (= L6 = ΔD). The added frame F is formed.

In the frame material 10, the first outer plate groove 26 formed in the base material outer plate 23 is formed in the proximal end portion 23 a in the short direction of the base material outer plate 23 and is fitted to this. The first outer plate ridge 35 of the cover material outer plate 33 is formed at the distal end portion 33 b of the cover material outer plate 33 in the short direction.
Therefore, when the vertical frame material cover material 30v is fitted into the vertical frame material base material 20v during the construction of the vertical frame material Fv, the outer surface of the base material outer plate 23 extends to the base end portion 23a. It is covered with the outer plate 33 and cannot be seen from the outside. In particular, in this example, both the first outer plate groove 26 and the first outer plate protrusion 35 are formed in a tapered shape. Therefore, when the vertical frame material cover material 30v is fitted into the vertical frame material base material 20v, the short-side end portion 33b of the cover material outer plate 33 and the short-side base of the base material outer plate 23 are arranged. The end 23a is abutted linearly.
Therefore, the outer surface of the base material outer plate 23 is covered with the cover material outer plate 33 with almost no gap, and exhibits a very excellent appearance.
Further, on the outer surface of the base material inner plate 22, a step corresponding to the thickness t1 of the cover material 30 is provided in advance between a portion A1 on the distal end portion 22b side and a portion A2 on the proximal end portion 22a side in the short direction. It has been. Therefore, when the vertical frame material cover material 30v is fitted into the vertical frame material base material 20v, the outer surface of the base material inner plate 22 (the portion A2 on the base end 22a side) and the cover material inner plate 32 It is finished flush with the outer surface.

  Further, when the first outer plate ridge 35 is cut off during the construction of the horizontal picture frame material Fs, the second outer plate ridge 36 is positioned at the front end portion 33 b of the cover material outer plate 33 in the short direction. Therefore, even when the horizontal frame material Fs is constructed, as in the construction of the vertical frame material Fv, the outer surface of the base material outer plate 23 is covered with the cover material outer plate 33 up to the base end portion 23a. It cannot be seen from the outside. Further, since the second outer plate ridge 36 is also formed in a taper shape, even when the vertical frame material cover material 30v is fitted into the vertical frame material base material 20v during the construction of the horizontal frame material Fs, the cover is covered. The distal end portion 33 b in the short direction of the material outer plate 33 and the proximal end portion 23 a in the short direction of the base material outer plate 23 are linearly abutted, and the outer surface of the base material outer plate 23 is substantially the cover material outer plate 33. It will be covered without any gaps and will also have an excellent appearance.

As shown in FIG. 4, the expanded frame F after construction is provided with a rail member L for the inner window material W on the horizontal frame material Fs, and then an inner window made of a glass plate and a sash frame surrounding the glass plate. A material W is fitted into the inner window. Moreover, the cap member C is attached to the both ends of the longitudinal direction of the vertical frame material Fv. Specifically, after the cap member C is fitted to both ends of the vertical frame material Fv, as shown in FIG. 9, it is screwed with two screws and screw holes 22c and 23c. By attaching the cap member C in this manner, the hollow portion of the frame material 10 can be concealed, and the cover material 30 fitted to the base material 20 can be prevented from falling naturally due to gravity or being displaced by vibration.
In the above description, the vertical frame material Fv is first constructed and then the horizontal frame material Fs is constructed, but the construction order may be reversed.

As described above, according to such a frame material 10, it is possible to easily change the depth from one type of frame material 10 to two types of depth by a simple operation of separating the first outer plate projection 35 at the construction site. As shown in FIG. 3, when configuring the additional frame F having a specification in which a step is formed between the front end surface of the vertical frame material Fv and the front end surface of the horizontal frame material Fs, the vertical frame material and the horizontal frame are configured. It can also be used for materials.
Therefore, it is not necessary to form two types of base materials and cover materials using two different types of extrusion molds in order to construct at two types of depth, and the production cost of the frame material can be reduced. . Further, in this case, since only one type of frame material is prepared in advance, troublesome work during construction preparation is also reduced. Furthermore, regardless of the depth of construction, the base material outer plate is covered with the cover material outer plate, which is excellent in terms of appearance.

In the above example, the extension length L1 from the base end portion 22a of the base material inner plate 22 is formed larger than the extension length L2 from the base end portion 23a of the base material outer plate 23. . This is because the inner window material W is fitted into the inner peripheral side of the additional frame F on which the base material inner plate 22 is arranged, and comes into contact with the inner window material W, or a rail member for the inner window material W. This is because L is laid and is required to be stronger than the outer peripheral side of the additional frame F on which the base material outer plate 23 is arranged. By extending the extension length L1 in this manner, the inner window material W can be more reliably supported even in the lower horizontal frame material Fs that requires particularly high strength. On the other hand, since the outer peripheral side of the additional frame F is not required to be strong like the inner peripheral side, the extension length L2 is set to a length that can form at least a plurality of outer plate grooves 26, 27. That's fine.
Further, in this way, if the length L1 of the base material inner plate 22 extending from the base end portion 22a is set to a length that can exhibit sufficient strength, the inner plate formed on the base material inner plate 22 The positions of the concave grooves 24 and 25 may be formed on the base end portion 22a side.

In the above example, the number of the inner plate ridges 34 formed on the cover material inner plate 32 is only one, and when the inner plate ridges 34 are fitted into the first inner plate grooves 24, the depth is increased. It can be constructed in a small size, and when fitted in the second inner plate concave groove 25, the depth can be increased. With such a configuration, when the inner plate ridge 34 is fitted in the second inner plate groove 25, the first inner plate groove 24 is not covered with the cover material 30 and is exposed. . However, the exposed portion is a portion that is hidden when the rail member L is laid or the inner window member W is fitted. Therefore, the number of the inner plate ridges 34 formed on the cover material inner plate 32 in this way is one, and the first inner plate groove 24 to which the inner plate ridges 34 are not fitted is exposed. However, the appearance of the additional frame F is not affected.
In contrast, in the above example, the number of the outer plate ridges 35 and 36 formed on the cover material outer plate 33 is plural (two). Here, it is assumed that the number of the outer plate ridges is only one, and the one outer plate ridge is fitted into the first outer plate groove 26 to reduce the depth, and the second outer plate groove 27 is provided. It is also possible to make the construction to increase the depth by fitting it into the. However, in that case, when the outer plate protrusion is fitted in the second outer plate groove 27 and the depth is increased, the first outer plate groove 26 is not covered with the cover material 30 and is exposed. It becomes a state. The exposed part is located on the outer peripheral side of the additional frame F and is a part that is touched by human eyes, and adversely affects the appearance of the additional frame F. Therefore, the number of the outer plate ridges formed on the cover material outer plate 33 needs to be the number according to the depth type (two in this example) in appearance.

  In addition, although the number of the inner plate ridges 34 is sufficient as described above, depending on the case, the outer plate ridges 35 and 36, the inner plate grooves 24 and 25, the outer plate grooves 26 and 27, and Two of the same number may be used. In that case, the two inner plate ridges are also formed so as to be separable, and when the depth is to be reduced, the inner plate ridges on the tip side are the same as in the case of the outer plate ridges 35 and 36. It will be used after separating.

  In the above example, the number of the outer plate ridges 35, 36, the inner plate grooves 24, 25, and the outer plate grooves 26, 27 are both two, and the distance between the two outer plate ridges 35, 36 is as follows. It was set as the form which can be constructed in two types of depth by setting it as the form which can be separated easily. However, the number of outer plate ridges, inner plate grooves, and outer plate grooves is not limited to two and may be plural. For example, when three of these are formed and the three outer plate ridges can be easily separated, it can be applied to three different depths. If it is such a frame material, for example, one type for a plurality of locations where the depths of the additional frame frames required for different reasons such as the inner window of the house veranda and the inner window of the kitchen are different. Can be handled with frame material.

  Moreover, in the above example, the notch groove 37 is formed in the separation position, so that it can be separated at an accurate position and can be easily separated at the construction site. However, the cutout groove 37 does not necessarily have to be formed. For example, only a separation line that serves as a mark for a separation position may be provided, or a mark or the like may not be provided.

  In the above example, aluminum is exemplified as the material of the base material 20, but other metals may be used as long as the material satisfies characteristics such as strength and formability suitable for the base material 20 of the frame material 10. There is no. Moreover, although the vinyl chloride resin was illustrated as a material of the cover material 30, there will be no restriction | limiting if it is resin which satisfies the characteristics, such as workability suitable for the cover material 30 of the frame material 10, and a moldability. Moreover, there is no restriction | limiting in particular also in the material of the cap member C, For example, the acrylonitrile styrene acrylate etc. which are provided with the elasticity suitable for the cap member C and favorable weather resistance etc. can be used.
