A screw hole h for means b is formed.

This is because the base material E121 of the lower frame 12 is formed by extrusion molding using a recycled resin material. Since there is a possibility that sufficient strength cannot be obtained for mounting the lower frame 12, the mounting portion (mounting piece portion 121f and angle portion 121g) for mounting the lower frame 12 to the opening of the skeleton is made of unused resin material. It is formed by

With the above configuration, accuracy is improved when screw holes are provided in the mounting portions (mounting piece portion 121f and angle portion 121g) for mounting the lower frame 12 to the opening of the frame, and strength is reduced by providing screw holes and the like. is limited, so the lower frame can be securely attached to the opening of the building frame or the like.

In addition, in the lower frame 12 of the above-described embodiment, the mounting portion formed from the unused resin material is not limited to the mounting piece portion 121f and the angle portion 121g for mounting to the opening of the frame. A mounting portion such as a screw hole provided in a horizontal member (or a vertical member attached to the horizontal member) to be mounted to the horizontal member may be formed of an unused resin material.

-Embodiment of door frame-
As shown in FIG. 4, the door frame 33 of the outer shoji 3 of this embodiment has a door frame main body 331 which is a main body member of the door frame 33 and a rim 332 which is a separate member. Surface layers F331 and F332 made of unused resin material are provided on the surfaces of base materials E331 and E332, respectively.

Specifically, the base material E331 of the door frame main body 331 includes a door frame main body portion E331a having a hollow portion, a glass frontage wall portion E331b formed on the inner periphery of the door frame main body portion E331a on the outdoor side, An outer peripheral groove E331c is formed on the outer periphery of the door frame main body E331a, and a surface layer F331 made of an unused resin material is provided on the indoor side A21 and the outdoor side A22 of the door frame 33.

The base material E332 of the rim 332 has a hollow rim main body E332a, and a surface layer F332 made of an unused resin material is provided on the indoor side surface A23 of the rim main body E332a.
The surface layers F331 and F332 made of unused resin material may not be provided on the entire surface of the base materials E331 and E332, and may be provided only on the surface of the portion where the door frame 33 of the outer shoji 3 is exposed. may be

A mounting portion 331d for mounting the rim 332 is integrally formed with the base material E331 and the surface layer F331 from an unused resin material on the indoor-side outer periphery of the door frame main body portion E331a of the door frame main body 331. In addition, on the outer periphery of the pressing edge body portion E232a of the pressing edge 332, a mounting portion F332b that engages with the attached portion F331d of the door frame body portion E331a is integrally formed with the base material E332 and the surface layer F332 by an unused resin material. is formed in

That is, the mounting portion F331d and the mounting portion F332b for mounting the pressing edge 322, which is a separate member, to the door frame main body 331 of the door frame 33, which is a main body member, are formed of an unused resin material.

This is because the base material E331 of the door frame main body 331 and the base material E332 of the rim 332 of the door frame 33 are formed by extrusion molding using a recycled resin material. The extruded shape of the mounting part and the mounted part for mounting is not stable, and the strength of the engaging part is reduced, so that sufficient accuracy and strength can be obtained for mounting the rim 332 to the door frame body 331. Since there is a possibility that the rim 332 cannot be attached to the door frame main body 331, the mounting portions (mounted portion F331d of the door frame main body E331a and mounting portion F332b of the rim 332) for mounting the rim 332 to the door frame main body 331 are made of unused resin material. It is formed.

-Other Configurations for Covering the Unused Resin Material Portion-
Resin building materials using recycled resin have been described above, but in resin building materials using recycled resin, for parts where it is difficult or inefficient to form a surface layer with virgin resin, caps and the like made of virgin resin are used. Exposure may be prevented by another member.

For example, as shown in FIG. 5A, there are cases where the outer peripheral surface of the meeting frame 34 of the outer shoji 3 cannot be completely covered with the meeting cover 343 . Further, when the meeting frame 34 is notched or processed, the unused resin F34 may be scraped off, and the recycled resin E34 may be exposed.
In such a case, as shown in FIG. 5(b), the part where the recycled resin E34 of the meeting frame 34 is exposed is covered with the recycled resin E34 by the end parts 5 such as the anti-vibration part, the cover member, and the waterstop member. exposure may be prevented.

6, a slide plate that enables locking by moving a lock pin 45b up and down by operating a handle 45a is provided on the outer peripheral surface of the door frame (right vertical frame) 44 of the shoji 4. A slide plate groove 44a may be provided for slidably retaining 45c.

As shown in FIG. 7A, most of the slide plate groove 44a provided on the outer peripheral surface of the door frame 44 is arranged with the slide plate 45c, so the slide plate 45c of the slide plate groove 44a is arranged. The inner surface of the part has no exposed recycled resin even though there is no surface layer of virgin resin.

However, as shown in FIG. 7B, since the slide plate 45c is not arranged over the entire length of the door frame 44, the recycled resin E44 is exposed in the upper and lower regions x of the slide plate groove 44a. There was danger.
Therefore, in the fitting made of the resin building material of the present embodiment, end caps 6 are detachably arranged at the upper and lower ends of the slide plate groove 44a to prevent exposure of the recycled resin E44 in cooperation with the slide plate 45c. are doing.
The end cap 6 will be described below using the end cap 6 arranged on the top of the door frame 44 .

In the shoji 4 of the fittings of this embodiment, the upper stile 41, the lower stile and the left and right vertical stiles 43 and 44 have the same cross-sectional shape. The frames are assembled by contacting each other and welding or the like, and slide plate grooves are formed on the outer peripheral surface of the shoji 4 .

As shown in FIGS. 7(a) and 7(b), a slide plate 45c for moving the lock pin 45b up and down is arranged in the slide plate groove 44a of the door frame 44 so as to be vertically movable. In the upper region x of the slide plate groove 44a including the movement region y of the upper end portion of the slide plate 45c, the slide plate groove 44a could not be completely covered by the slide plate 45c.
The end cap 6 is arranged to cover the upper region x of the slide plate groove 44a.

As shown in FIG. 8(a), the end cap 6 attached to the corner of the shoji 4 has a substantially L-shaped cross section having a vertical plate 6a and an upper plate 6b. A slide leg portion 6c is provided to be inserted into the slide plate groove 44a of the right vertical frame 44, and the bottom surface (rear surface) of the upper plate 6b is engaged with a slide plate groove 41a formed on the outer peripheral surface of the upper frame 41. A stop portion 6d is provided.
The end cap 6 has a fin portion 6e formed by extending the lower portion of the vertical plate 6a downward from the lower end of the slide leg portion 6c.

8(b), the slide leg 6c of the end cap 6 is positioned above the slide plate groove 44a of the right vertical frame 44 with respect to the joint between the upper frame 41 and the door frame 44. As shown in FIG. Attached so that it can be inserted more.
The end cap 6 with the slide leg portion 6c inserted into the slide plate groove 44a eventually engages the locking portion 6d formed on the lower surface of the upper plate 6b with the slide plate groove 41a of the upper frame 41, thereby As shown in 9(a) and 9(b), it is fixed to the corners of the upper frame 41 and the door frame 44. As shown in FIG.

The end cap 6 fixed to the corner of the upper frame 41 and the right vertical frame (door frame) 44 covers the movement area y of the upper end of the slide plate 45c of the slide plate groove 44a with the fin 6e. The upper region x of the slide plate groove 44a can be covered by the plate 6a and the fin portion 6e.
That is, the end caps 6 fixed to the corners of the upper frame 41 and the right vertical frame 44 can cover the portions of the slide plate grooves 44a of the vertical frame 44 where the recycled resin E44 is exposed.

With the above configuration, for a resin building material made up of a plurality of resin members, it is possible to form the connecting portion (mounting portion) between the resin members with an unused resin material, thereby stabilizing the shape of the mounting portion for reliable mounting. At the same time, the risk of breakage or the like can be reduced.

In the resin building material of the above embodiment, the mounting portions made of the unused resin material are limited only to the mounted portion provided on the door frame main body of the door frame and the mounting portion provided on the rim main body of the rim. For example, the engagement claw (attachment portion) 233c for attaching the cover member 233 of the door frame 23 of the inner shoji 2 to the door frame main body 231a is formed of an unused resin material. Any attachment portion of the building material may be formed from virgin resin material.

Also, in areas where it is not efficient to cover with unused resin material in terms of processing and manufacturing, a cap or the like can be placed to prevent the recycled resin from being exposed, thus saving unused resin. Also, it is possible to prevent a decrease in productivity.

In the present embodiment, the surface layer made of the unused resin material is not provided on the non-exposed surface of the base material constituting the resin building material, but it may be provided as necessary.

In addition, the above technique can be applied to any part of the frame body or the frame body that constitutes the resin fittings. In addition, the present invention is not limited to resin building materials, and can be applied to the resin portion of building materials for fittings that combine aluminum and resin.

It goes without saying that the above-described embodiments do not limit the invention described in the claims, but are treated as examples.
