Conventionally, as fittings with improved heat insulating performance, window frames and shoji stiles made of synthetic resin have been known (see Patent Document 1). In the synthetic resin shoji of Patent Document 1, the reinforcing core material is fitted in the hollow portion of the stile other than the upper stile to improve the rigidity of the lower stile and the vertical stile made of synthetic resin.

Jitsukaisho 58-47691

Since the reinforcing core material is a metal member such as a steel material, it becomes a thermal bridge, and there is a problem that the heat insulating performance of the synthetic resin shoji is deteriorated. Further, in Patent Document 1, since the reinforcing core material is fitted in the hollow portion of the stile, the cross-sectional shape of the reinforcing core material is restricted by the shape of the hollow portion, and the cross-sectional shape of the stile may be complicated. could not. Therefore, in Patent Document 1, there is a problem that the stile made of synthetic resin cannot have a complicated cross-sectional shape, and the fittings that can be used are also limited.

An object of the present invention is to provide a frame material for fittings and fittings which have a high degree of freedom in cross-sectional shape and can improve heat insulation and rigidity.

The present invention is a frame material for fittings including a resin frame main body portion having a hollow portion and a reinforcing material arranged in the hollow portion, and the reinforcing material is a heat insulating member and an outdoor surface of the heat insulating member. It is configured to include a metal member fixed to at least one of a surface portion or an indoor surface portion, and is fixed to the frame main body portion.

In the present invention, the outdoor surface portion of the heat insulating member is a portion of the heat insulating member that is arranged facing the outdoor side when the fitting is constructed using the frame material for fittings of the present invention, and the indoor surface portion is heat insulating. It is a part of the member that is arranged facing the indoor side. Therefore, the outdoor surface portion and the indoor surface portion of the heat insulating member are provided apart from each other in the prospective direction of the fitting, that is, the indoor / outdoor direction.
Then, according to the frame material for fittings of the present invention, the metal member is fixed to the outdoor surface portion or the indoor surface portion of the heat insulating member, and the heat insulating member and the metal member are arranged in the indoor / outdoor direction and fixed with screws or an adhesive. Since the reinforcing material is used, the heat insulating property and rigidity of the frame material for fittings can be improved. That is, as compared with the case where the reinforcing material is composed only of the metal material, since the heat insulating member is interposed, it is possible to prevent the entire reinforcing material from becoming a thermal bridge, and the heat insulating performance of the frame material for fittings can be improved accordingly. ..
Further, since the reinforcing material includes not only the heat insulating member but also a metal material, the rigidity of the frame material for fittings can be improved as compared with the case where the reinforcing material is composed of only the heat insulating member.
Further, since the reinforcing material arranged in the hollow portion of the frame main body is fixed to the frame main body, if the reinforcing material is configured to be able to be arranged in the hollow portion, it can be attached to the frame main body by fixing means such as screws or rivets. Can be fixed. Therefore, it is not necessary to match the shapes of the hollow portion and the reinforcing material. Therefore, by fitting the reinforcing material in the hollow portion, the degree of freedom in the shape of the hollow portion and the reinforcing material can be increased as compared with the case where the reinforcing material is arranged without being fixed to the frame main body portion, and the frame for fittings. It is possible to easily realize slimming of the material, and to improve the degree of freedom in the arrangement position and shape of the metal member in the reinforcing material. Therefore, the frame material for fittings can be appropriately reinforced.

In the frame material for fittings of the present invention, it is preferable that the heat insulating member of the reinforcing material and the frame main body portion are fixed with screws.
The reinforcing material is preferably arranged over the entire length of the frame material for fittings in the longitudinal direction, and therefore, the reinforcing material is screwed at a plurality of locations along the longitudinal direction. At this time, in order to automate the screwing work, it is preferable to screw with a drill screw. Chips are generated when using a drill screw. When a drill screw is screwed into a metal member of a reinforcing material, metal chips are generated, and if chips that could not be removed even after removing the chips remain in the frame material for fittings, use of fittings. Depending on the environment, rust water and scratches may occur due to chips. Therefore, it is necessary to carefully remove the metal chips, the workability at the time of screwing is lowered, and the productivity of the frame material for fittings is also lowered.
On the other hand, in the present invention, since the heat insulating member and the frame main body are fixed with screws instead of the metal member of the reinforcing material, only resin chips are generated, and the generation of metal chips is prevented. it can. Therefore, even if the chips that could not be removed by the chip removing work remain, the chips are made of resin, so that the generation of rust water and scratches due to the chips can be prevented.

In the frame material for fittings of the present invention, the heat insulating member is formed in a rectangular frame shape in cross section, and the metal member includes an outdoor side metal member fixed to the outdoor surface portion of the heat insulating member and the indoor metal member of the heat insulating member. It is preferable to provide an indoor metal member fixed to the surface portion.
Since the outdoor side metal member and the indoor side metal member are fixed to the outdoor surface portion and the indoor surface portion of the heat insulating member to form a reinforcing material, the heat insulating member can be arranged between the indoor and outdoor metal members, and the indoor and outdoor metal members can be arranged. Since they are not in contact with each other, thermal bridges do not occur, and deterioration of heat insulation performance can be reduced. Further, since the indoor and outdoor metal members are separate bodies, metal members having different materials, shapes, plate thicknesses, and the like can be arranged. Therefore, the degree of freedom in design as a reinforcing material can be improved, and indoor and outdoor metal members can be set according to the shape of the hollow portion of the frame main body and the required strength.

In the frame material for fittings of the present invention, the heat insulating member is preferably made of fiber reinforced plastic.
As a heat insulating member of a reinforcing material, it has higher heat insulating properties than metal materials, has excellent fire resistance and strength compared to synthetic resin materials, and has a smaller coefficient of linear expansion than synthetic resin materials and metal materials, and the amount of expansion and contraction with respect to temperature changes. Since a fiber reinforced plastic (hereinafter sometimes referred to as "FRP") that can reduce the size of the plastic is used, it is possible to provide a frame material for fittings having excellent heat insulation performance, fire resistance performance, strength, and low elasticity.
Further, when the drill screw is screwed into the synthetic resin material, it is necessary to devise a structure such that the drill screw is screwed at two places via the hollow portion. On the other hand, if the heat insulating member is made of FRP, the drill screw can be screwed in without any structural ingenuity such as through a hollow portion, the shape of the heat insulating member can be simplified, and the productivity can be improved.

In the frame material for fittings of the present invention, the metal member is preliminarily machined with screw holes for fixing functional parts to be attached to the frame body portion, and the metal member is formed through the holes formed in the frame body portion. It is preferable that the functional component is attached to the frame main body by a screw screwed into the screw hole of the metal member.
According to the present invention, since the functional component can be screwed to the metal member of the reinforcing material by using the screw hole machined in advance, the positional accuracy of the functional component can be improved. Further, since the screw holes of the metal member can be processed before the reinforcing material is attached to the frame main body portion, it is possible to prevent chips from remaining in the frame material for fittings. The functional part is a part used to realize various functions in the fitting, for example, a crescent for locking the fitting, a crescent receiver, and the like.

The present invention is a fitting configured by framework of a plurality of fitting frame materials having a resin frame main body having a hollow portion, and is for at least a part of the plurality of fitting frame materials. The frame material is characterized in that it is composed of the frame material for fittings.
According to the present invention, by using the frame material for fittings in a portion where strength and heat insulation are required, such as a sliding window combination stile, the degree of freedom in cross-sectional shape can be increased in the combination stile and the like. , Insulation and rigidity can be improved. In addition, for fitting frame materials, such as door-end stiles and upper stiles, which require less strength than combined stiles, reinforcing materials containing only heat insulating members can be used, and heat insulating performance is improved accordingly. it can.

According to the frame material for fittings and fittings of the present invention, the degree of freedom in cross-sectional shape is high, and heat insulation and rigidity can be improved.

It is provided with the reinforcing members 314, 324 and 334.
The ridges 312, 322, and 332 are engaged with the engaging grooves formed in the stile body 321. A concave groove-shaped glass holding groove is formed between the ridges 312, 322 and 332 and the stile main body 311, 321 and 331 facing the ridges 312, 322 and 332. In the glass holding groove, an end portion of the double glazing 50 and a fall prevention member 40 for preventing the double glazing 50 from falling off are arranged. The fall-off prevention member 40 is a short piece material, and is fixed in the vicinity of the ends of the stiles 31 to 34, respectively.

The reinforcing members 313, 323, and 333 are made of fiber reinforced plastic (made of FRP) like the reinforcing member 25, and are long members having a rectangular cross section. The reinforcing members 313, 323, 333 are arranged in the hollow portion (hollow portion) formed in the stile main body 311, 321 and 331, and are arranged over the substantially overall length of the stile main body 311, 321 and 331 in the longitudinal direction. Has been done.
The reinforcing members 313, 323, 333 are attached to the stile body 311, 321, 331 by the drill screw 41. In the place where the fall prevention member 40 is arranged, the drill screw 41 is also used for attaching the fall prevention member 40.

Reinforcing materials 314, 324 and 334 are arranged along the bottom surface of the concave groove portion and the side surface on the outdoor side in the outer sash 3A, and are arranged along the bottom surface of the concave groove portion and the side surface on the indoor side in the inner sash 3B. .. The reinforcing materials 314, 324 and 334 are drill screws 42 screwed from the reinforcing materials 314, 324 and 334 into the reinforcing materials 313, 323 and 333 made of FRP via the stile main bodies 311, 321 and 331. It is attached to 331.

As shown in FIG. 4, each combination stile (vertical stile) 34 of the outer sash 3A and the inner sash 3B includes a stile main body 341 which is a frame main body portion, a ridge 342, and reinforcing members 350A and 350B. Then, an engaging groove for attaching the ridge 342 is formed on the stile body 341, a glass holding groove for holding the double glazing 50 is provided between the stile body 341 and the ridge 342, and the reinforcing material 350A is provided on the hollow portion 341A of the stile body 341. , 350B is arranged, which is the same configuration as the door end stile 33.
However, the combination stile 34 has a cross-sectional shape suitable for the combination stile 34 because the stile body 341 is provided with a smoke return or the like, or because functional parts such as the crescent 71 and the crescent receiver 72 are attached to the combination stile 34. The shape and structure are different from those of the door-end stile 33 in that it is said to be.

The reinforcing members 350A and 350B include a heat insulating member 351, an outdoor side metal member 352, and an indoor side metal member 353. Like the reinforcing members 313, 323, 333, the heat insulating member 351 is made of FRP and is a long member formed in a rectangular frame shape in cross section. The heat insulating member 351 includes an outdoor surface portion 351A facing the outdoor side, an indoor surface portion 351B facing the indoor side, and two prospective surface portions 351C connecting the outdoor surface portion 351A and the indoor surface portion 351B.
The outdoor side metal member 352 is a steel material formed in an L-shaped cross section. The indoor side metal member 353 is a steel material formed in a flat plate shape. These outdoor side metal member 352 and indoor side metal member 353 are long members having the same dimensions as the heat insulating member 351 and are fixed and integrated with the outdoor surface portion 351A and the indoor surface portion 351B of the heat insulating member 351. .. As a means for fixing the outdoor side metal member 352 and the indoor side metal member 353 to the heat insulating member 351, the strength required for functioning as the reinforcing materials 350A and 350B, such as screws, rivets, adhesives, and fitting structures, is provided. Any fixed structure may be used as long as it can be secured.
The reinforcing members 350A and 350B are attached to the stile body 341 by a drill screw 43 screwed from the glass holding groove of the stile stile 34. A plurality of drill screws 43 are provided at predetermined intervals along the longitudinal direction of the mating stile 34, that is, in the vertical direction, and also serve as attachment of the fall prevention member 40 at a place where the fall prevention member 40 is arranged. Further, the drill screw 43 is screwed into the heat insulating member 351 of the reinforcing members 350A and 350B, and is not screwed into the steel outdoor side metal member 352 and the indoor side metal member 353. Therefore, no metal chips are generated when the drill screw 43 is screwed. The structure for fixing the reinforcing members 350A and 350B to the frame main body 341, which is the frame main body, is not limited to the drill screw 43, and the force applied to the stile main body 341 such as screws, rivets, and adhesives is applied to the reinforcing material 350A, Any fixed structure may be used as long as it can be transmitted to 350B to improve the strength of the stile body 341.

A crescent receiver 72, which is a functional component, is attached to the combination stile 34 of the shoji 3A. Therefore, screw holes are formed in the indoor metal member 353 and the heat insulating member 351 of the reinforcing member 350A in accordance with the mounting position of the crescent receiver 72. Since this screw hole processing can be performed before the reinforcing material 350A is placed in the hollow portion 341A of the mating stile 34, even if chips are generated due to the screw hole machining of the indoor metal member 353, the mating is performed. It does not remain in the stile 34.
The crescent receiver 72 is attached to the combination stile 34 from the indoor surface side of the combination stile 34 via the crescent receiver 72 and the combination stile 34 with screws 75 screwed into the indoor side metal member 353 and the heat insulating member 351.

A crescent 71 is attached to the combination stile 34 of the shoji 3B. Therefore, a back plate 360 used for fixing the crescent 71 is attached to the reinforcing material 350B in the combination stile 34 with a drill screw 361. Since the drill screw 361 is screwed into the heat insulating member 351, it is possible to prevent the generation of metal chips.
Screw holes are machined in the outdoor side metal member 352 of the back plate 360 and the reinforcing member 350B in accordance with the mounting position of the crescent 71. The processing of the screw holes is also performed before the reinforcing member 350B is placed in the hollow portion 341A of the combined stile 34, so that metal chips do not remain in the hollow portion 341A. The crescent 71 is attached by screwing the screw 76 into the screw hole of the back plate 360 and the outdoor side metal member 352 from the prospective surface of the mating stile 34.

When the sliding window 1 is fireproof, the window frame 2 and the shoji frame 30 have a gap between the window frame 2 and the outer shoji 3A and the inner shoji 3B, and the shoji frame 30 and the double glazing 50 in the event of a fire. A heated foam material 80 is provided to close the gap between the two. The heat foam material 80 is a long tape material composed of heat-expandable graphite and the like, and when the temperature rises above a predetermined temperature (for example, about 150 to 200 degrees) in the event of a fire or the like, it foams to about 10 degrees. It expands about 40 times and functions as a flame shield.

In such a sliding window 1 of the present embodiment, the reinforcing members 350A and 350B arranged in the hollow portion 341A of the mating stile 34 are interposed between the outdoor side metal member 352 and the indoor side metal member 353 with the heat insulating member 351. Because of the structure, it is possible to suppress the deterioration of heat insulation performance as compared with the conventional metal reinforcing material. Therefore, it is possible to prevent the reinforcing members 350A and 350B from forming a thermal bridge at the combination stile 34 portion, and the sliding window 1 can be provided as a highly heat-insulated resin window.
Further, in the reinforcing materials 350A and 350B, since the heat insulating member 351, the outdoor side metal member 352, and the indoor side metal member 353 are combined, the outdoor side metal member 352 and the indoor side metal member 353 are made of the same metal material. It is not necessary to form it thickly. That is, the outdoor side metal member 352 and the indoor side metal member 353 can freely set the type of metal material, the dimensions such as the wall thickness, the shape, and the like. Therefore, the outdoor side metal member 352 and the indoor side metal member 353 can be set separately according to the hollow shape and the required strength of each part where the reinforcing materials 350A and 350B are provided, and the degree of freedom in designing the reinforcing materials 350A and 350B can be improved. ..
Further, the reinforcing members 350A and 350B can improve the I value (second moment of area) by arranging the outdoor side metal member 352 and the indoor side metal member 353 apart from each other indoors and outdoors with the heat insulating member 351 sandwiched between them. Therefore, the rigidity of the reinforcing materials 350A and 350B can be ensured even if the amount of the metal material used is reduced, and the heat insulating performance can be further improved.
Further, since the drill screws 43 and 361 are screwed into the heat insulating member 351 of the reinforcing members 350A and 350B and not screwed into the outdoor side metal member 352 and the indoor side metal member 353, metal chips remain between the mating stiles 34. It is possible to prevent the metal chips from being removed, and since the metal chips do not remain, it is possible to prevent the occurrence of problems due to red rust water and chip scratches.
Since the reinforcing material 25 provided on the frames 21 to 24 and the reinforcing material 313, 323, 333 provided on the frames 31 to 33 other than the combination stile 34 are also FRP materials, when the drill screws 41, 42, 250 are screwed in, It is possible to prevent the generation of metal chips, and even in these cases, it is possible to eliminate the work of removing the metal chips, and it is also possible to prevent the occurrence of defects due to red rust water and chip scratches.

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 shown in FIG. 5, the reinforcing material 350A may be fixed to the stile main body 341 by screwing the drill screw 43 into the outdoor side metal member 352 or the indoor side metal member 353 of the reinforcing material 350A. The same applies to the reinforcing material 350B. In this case, since the drill screw 43 is screwed into the metal members 352 and 353 instead of the FRP heat insulating member 351, the fixing strength of the reinforcing members 350A and 350B can be improved. At this time, even if metal chips are generated, the chips may be removed or used as fittings in a place where they do not come into contact with water in the usage environment.
Further, functional parts such as the crescent 71 and the crescent receiver 72 may also be attached using a drill screw.

The heat insulating member 351 constituting the reinforcing materials 350A and 350B is not limited to the FRP material, and may be a synthetic resin material as long as it has the necessary heat insulating performance and strength. Further, the outdoor side metal member 352 and the indoor side metal member 353 are not limited to the steel material, and may be any metal material having the required rigidity.
Further, the reinforcing members 350A and 350B are provided with metal members 352 and 353 on both sides of the outdoor surface portion 351A and the indoor surface portion 351B of the heat insulating member 351. It may be provided.
Further, although the reinforcing members 350A and 350B composed of the heat insulating member 351 and the metal members 352 and 353 are provided only on the combination stile 34, they may be provided on the door end stile 33, the upper stile 31, and the lower stile 32. Alternatively, it may be provided on the upper frame 21, the lower frame 22, and the vertical frames 23, 24 of the window frame 2.
Further, the fitting of the present invention is not limited to the sliding window 1, such as a single sliding window, a vertical sliding window, a horizontal sliding window, an inwardly tilting window, an outwardly tilting window, a raising and lowering window, an inwardly opening window, an outwardly opening window, and a FIX window. It can be used as various sash windows. Therefore, the shape and configuration of the reinforcing material attached to the frame material for the fitting may be selected according to the type of the fitting.
