Description

[Detailed description of the invention] [Field of industrial application] The present invention strengthens the attachment of the decorative rim by inserting the horizontal pieces of the decorative rim into the grooves formed on the sash and coated with an adhesive. The present invention relates to a decorative edge mounting structure that can provide a decorative edge and prevent unpleasant noises from occurring.

[Conventional technology]

For example, in a dry construction building where walls, floors, etc. are formed using architectural panels, sashes are attached to the openings such as windows of the architectural panels that form the outer wall, and The inner peripheral surface between the indoor end of the sash and the indoor surface of the opening, particularly the lower surface thereof, is decorated with a decorative edge that covers the space between them. However, conventional decorative edges were attached by simply inserting the horizontal piece into the groove that opens toward the indoor side of the sash, and by nailing the vertical piece to the indoor side of the architectural panel. The mounting strength is poor due to the variation in the dimensional accuracy of the decorative rim, which is made of a bent body and is relatively easily deformed. Moreover, as a result of the formation of a cavity below the decorative rim, a trampling load is applied to the decorative rim. Sometimes, the mating parts tend to come off easily, and the horizontal pieces dance in the grooves, causing contact noises, rattling noises, etc. due to wind blowing.
The drawback was that it produced a squeaking sound. In addition, this phenomenon becomes particularly noticeable when the construction panels are designed for use in cold regions and have a large thickness and the horizontal pieces of the decorative edges are long.

The purpose of the present invention is to provide a decorative edge mounting structure (hereinafter referred to as structure) that can solve the above-mentioned problems by attaching the horizontal piece to a groove coated with adhesive in advance. An example will be explained based on the drawings.

The figure exemplifies a case in which the structure is employed for forming windows in a dry construction building using architectural panels to form external walls and the like.

The structure is such that adhesive A is applied to grooves 4 provided in the lower frame material 3 of the sash that is attached to the opening 2 of the architectural panel P.
is applied, and the horizontal piece 35 of the decorative edge 7 is fitted and fixed. For example, an inner frame material 9 made of a channel-shaped material is installed around the circumference with its groove portion facing outward, and an exterior plate 12 is placed on the outer wall side and the interior side of the inner frame material through base materials 10 and 11, leaving an opening 2. A plate 13 is attached, and the inner circumferential surface of the opening 2 is formed by the base materials 10 and 11, the exterior plate 12, the interior plate 13, and the web 15 of the inner frame material 9. The sash is located at the opening 2 on the inner circumferential surface.
The lower frame material 3 includes a front leg piece 20 and a rear leg piece 21 that come into contact with the outer wall surface T of the architectural panel P, that is, the outer surface of the exterior plate 12.
Rails 23 and 24 for sliding window glass and a guide groove 25 into which a screen door or the like is fitted are formed on the upper surface thereof, and a connecting piece is provided to connect the upper ends of the front leg piece 20 and the rear leg piece 21.

The lower frame material 3 has a smaller depth than the architectural panel P, so that the rear leg piece 21 stands up on the lower surface S and on the indoor surface R side, and furthermore, the rear leg piece 21 and the indoor surface R An exposed portion in which the indoor side portion of the lower surface S is exposed is formed between the lower surface S and the lower surface S.

Further, the rear leg piece 21 has a horizontal lower overhang piece 29 that is bent toward the outdoor side above the base end 27, and a connecting piece that stands up at the end of the lower overhang piece 29 on the outer wall surface side. A vertical piece is provided which is connected to the indoor end of the chamber.

Further, the upright piece and the lower overhang piece 29 are provided at the upper end of the upright piece, and the lower overhang piece 29 is provided at the upper end of the upright piece.
9 is a continuous section that opens toward the indoor side by a horizontal upper overhanging piece 32 that separates the booth and just above it and projects horizontally toward the indoor side and has a downwardly hanging piece 30 at the indoor end. A groove 4 is formed.

The decorative edge 7 has a cross section L having the horizontal piece 35 and a vertical piece 36 that is bent downward along the interior surface R.
A cross is formed on the surface of the board made of wood.
It is made by bending a decorative board to which a decorative sheet such as a synthetic resin sheet is attached. Further, a backing material 37 is attached to the vertical piece 36 on the surface facing the outer wall surface T, and the horizontal piece 35 covers the exposed portion of the lower surface S and decorates the opening 2. At the bottom,
A bent piece is formed which has the same width as the thickness of the backing material 37 that is brought into contact with the indoor surface R and is bent along the lower surface of the backing material 37 so that its tip touches the indoor surface R.

In addition, the horizontal piece 35 has grooves 4 coated with adhesive A.
It is inserted and fixed in place.

By using an adhesive A that can bond metal and wood materials, has appropriate flexibility even after curing, and has shrinkage properties upon curing,
This can prevent the adhesive A from flowing out from the groove 4 to the upper surface of the horizontal piece 35 during curing. As such adhesive A, a vinyl acetate adhesive is preferably used,
Adhesives with various types of shrinkage can be used, such as those that shrink due to condensation, polymerization, etc., those that shrink due to evaporation of solvent, and those that are in the hot melt format and shrink as the temperature decreases. The amount of application is set so that when the groove 4 is inserted, the inside of the groove 4 is almost filled. Note that the hanging piece 30 at the indoor end of the upper overhang piece 32 serves to prevent the adhesive A from flowing out onto the upper surface of the horizontal piece 35. Further, the vertical piece 36 is adjacent to the interior surface R of the backing material 37 and is nailed using decorative nails or the like.

However, in the structure of the present invention, the tip of the horizontal piece 35 is fixed within the groove 4 using adhesive A, so that even when a downward force is applied to the horizontal piece 35, the groove 4 and the horizontal piece 35 are not connected to each other. contact noise etc. can be prevented, and pulsating noise etc. caused by wind etc. can be effectively suppressed.

As mentioned above, the structure of the present invention is that the horizontal piece of the decorative edge is fixed by fitting it into the groove of the sash bottom frame material that has been coated with adhesive in advance, so it is less expensive than applying adhesive to the horizontal piece. The adhesive can be sufficiently applied to the grooves, and the adhesive between the grooves and the horizontal piece can be filled without any gaps, increasing the installation strength and preventing squeaks and the like. In addition, the groove is formed using the lower overhang piece of the rear leg piece that protrudes toward the outdoor side, so
It has excellent rigidity and increases the support strength of horizontal pieces. Further, the upper overhanging piece is provided with a downward hanging piece, and by bringing the lower end of the hanging piece close to the upper surface of the horizontal piece of the picture frame, the movement of the horizontal piece being inserted can be reduced and the installation can be performed without play. Furthermore, when inserting the horizontal piece while bringing the upper surface of the horizontal piece of the picture frame close to this hanging piece, this hanging piece prevents the adhesive inside the groove from spilling out onto the upper surface of the horizontal piece, and the groove is inserted instead of the horizontal piece. Since the adhesive is applied to the horizontal piece, there is no scraping of the adhesive by the hanging piece when inserting the horizontal piece when the adhesive is applied to the horizontal piece in advance, making it possible to perform fixing work with a good finish. Also, the backing material of the vertical material is
By attaching it to the indoor surface, it backs up the vertical material, increases rigidity, and increases the installation strength, and the bent piece also decorates the bottom surface of the backing material, improving its appearance and providing excellent effects. I can play it.
