DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative member for covering an end face of an exterior material attached to a wall of a building around an opening such as a window of a building, and using the decorative member. Regarding the structure around the opening.

[0002]

2. Description of the Related Art In some cases, a long exterior material such as a lightweight concrete plate is closely adhered to an outer wall surface of a building. When an opening such as a window is formed on the wall of the building, if the exterior material is vertical, horizontal,
Irrespective of the difference in thickness, it is unavoidable that the end face (side end face or cut edge) of the exterior material is exposed around the opening. The side end surface of the exterior material and the cut edge of the cut edge are not necessarily sufficiently waterproof, and also lack designability. Therefore, it is necessary to cover the end face of the exterior material to be attached to the wall of the building by some means around the opening.

When the opening is a window, a window frame sash is often attached to the opening. When the sash is an external sash or a semi-external sash, the sash may be able to cover the end surface of the exterior material, but even in that case, the sash surface and the end surface of the exterior material It is necessary to cast a sealant between them. Further, when the thickness of the exterior material is wider than the overhang portion of the sash, a part of the end face portion is exposed outside beyond the sash, and it is necessary to separately cover the exposed portion. If the window frame sash is an internal sash, the sash cannot cover the end surface of the exterior material, so it is absolutely necessary to cover the entire end surface by some means.

As a means for achieving this, conventionally, for example, a resin material or a thin metal plate having a portion having a substantially U-shaped section has been used as a drainer (Japanese Patent Laid-Open No. 10-292502). , Heikai 3-351
No. 23, Japanese Utility Model Application Laid-Open No. 63-119708, etc.). In these cases, the end face (side end face or cut edge) of the exterior material is inserted into a portion having a substantially U-shaped cross section to cover the end face and prevent rainwater from entering.

[0005]

However, this kind of conventional decorative member around the opening is merely an elongated one, and special consideration is given to the corner of the opening. Not. In addition, when fixing, the decorative member around the opening is often fixed to the base material by means such as screwing or nailing, and in order to ensure the sealing performance of the nailed part such as screws or nails, a separate sealink material is required. It may be necessary to cast it.

Further, a plurality of types of exterior materials having different thicknesses are used (for example, 12 mm thick, 18 mm thick).
Thickness, 25mm thickness, etc.), and decorative members around the opening are individually made with a cross-sectional thickness corresponding to the plate thickness. At the construction site, it is necessary to prepare multiple types of decorative members for each type of plate thickness. Is done.

[0007] The present invention has been made in view of such circumstances, and makes it easy and reliable to attach to a base material including a corner portion regardless of the size of an opening such as a window. Another object of the present invention is to provide a decorative member around an opening and a structure around the opening using the decorative member, which can surely prevent rainwater from entering from a mounting portion.

Another object of the present invention is to provide a decorative member around an opening which can be easily installed on site using the same decorative member around the opening even when exterior materials having different thicknesses are used. Still another object of the present invention is to provide a decorative member around an opening capable of positively improving the appearance design around the opening.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a decorative member around an opening according to the present invention comprises: a rail fixed to a base material of a building along four circumferences around an opening of a building; And an exterior material end cover member that is arranged along the entire four circumferences of the opening of the building when attached to the rail, and the exterior material end cover member is attached to the building. Characterized in that it has a substantially U-shaped groove in cross-section, into which the end face portion of the exterior material located along the opening of (1) can be fitted.

In order to construct a structure around an opening of a building using the above-described decorative member around the opening, first, the long rail is cut in accordance with the size of the opening, and is cut. It is fixed to the surrounding base material by an appropriate means such as screwing or nailing. The exterior material end face cover member cut in advance to a predetermined length and shape is fixed to the rail fixed in this manner by a system-fitting mode such as fitting without using screws or nails. Install along the entire circumference. When attaching the exterior material to the wall surface of the building, the exterior material is attached while the end surface portion of the exterior material is fitted into the substantially U-shaped groove in cross section of the exterior material end surface cover member that has already been attached.

In the construction around the opening, the surface of the screw or nail used to attach the rail to the base material of the building is covered from the outside by the cover member of the exterior material end surface, and is not exposed to the outside. For this reason, high sealing performance is ensured, and infiltration of rainwater from fixing parts such as screws and nails is prevented. Also, only the outer side wall surface of the exterior material end face cover member appears on the outside, but the exterior material end face cover member can be formed into an arbitrary shape by extrusion molding of an aluminum material or the like, and the pattern of the outer side wall surface can be formed. Can also be added as appropriate. Thereby, the construction structure around the constructed opening can have high appearance design.

In the decorative member around the opening according to the present invention,
The exterior material end face cover member includes, for example, a long basic member used for the upper and lower horizontal portions and the left and right vertical portions of the window portion, and a corner member formed according to the angle of the corner of the opening portion. You may make it. Further, depending on a construction mode, a joining member for joining the basic member and the corner member may be provided. They are appropriately cut at the factory or at the construction site in accordance with the size of the opening, and are integrated on rails with the connecting members interposed as necessary. For this reason, the assembling accuracy is increased, and the sealing performance at the corner is reliably ensured.

[0013] In a preferred aspect, the exterior material end face cover member further includes a partition wall formed inside the substantially U-shaped groove in cross section, and the height of the partition wall defines the exterior material end face cover member. Lower than the height of the outer side wall surface. In a further preferred aspect, two or more partitions are provided, and the height of each partition is gradually reduced from the outer side wall surface to the inner side wall surface of the exterior material end face cover member.

In this case, the inside width of the groove having a substantially U-shaped cross section is adjusted to the thickest (for example, 25 mm) of the exterior material to be used, and the substantially U-shaped cross section is used. By adjusting the inward width between the inner side wall surface of the groove and each of the partition walls to a smaller thickness (for example, 18 mm and 12 mm), the thickness of the plate can be reduced while using the same exterior material end face cover member. It is easy to cope with construction for a plurality of different exterior materials (in this case, three types of exterior materials).

[0015] In the case of using the exterior material end face cover member for an exterior material having a small thickness, a portion located outside the partition wall suitable for the thickness of the exterior material is unnecessary as a construction structure around the opening. Part. Therefore, it is desirable to remove such unnecessary portions by appropriate means such as cutting with a cutter. For this purpose, in a preferred embodiment, a thin portion is formed on the bottom surface along the outer surface of each of the partition walls of the exterior material end face cover member. Thus, unnecessary portions can be easily removed by using the thin portions, and a high appearance design can be easily maintained by a simple operation.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. In the decorative member around the opening shown in the figure, the exterior material end face cover member is a basic member 10
And a corner member 20. The connecting member 30 and the rail 40 are further provided. First, each member will be described.

The basic member 10 is made by extruding aluminum, and as shown in FIGS.
It is a long channel material having a groove having a substantially U-shaped cross section. As shown in FIG. 8, the basic member 10 includes an outer side wall surface 11, a bottom surface 12, and an inner side wall surface 13. The outer side wall surface 11 and the inner side wall surface 13 have substantially the same height. I have. Two parallel male dovetail grooves 14a and 14b are formed on the rear side of the inner side wall surface 13 along the longitudinal direction. The upper edge of the outer side wall surface 11 is a rib 11a which is bent in a U-shape inward (toward the inner side wall surface 13), and is formed between the inner surface of the rib 11a and the inner side surface of the inner side wall surface 13. The distance is 25 mm in this example.

On the bottom surface 12, first and second two partition walls 15 and 16 parallel to each other are integrally formed in parallel with the outer side wall surface 11 and the inner side wall surface 13, respectively.
Similarly to the upper edge of the outer side wall surface 11, the ribs 15a, 1
6a are formed. The heights of the two partition walls 15 and 16 are both lower than the heights of the outer side wall surface 11 and the inner side wall surface 13, and the height of the first partition wall 15 closer to the outer side wall surface 11 is the inner side wall surface 13. Is higher than the height of the second partition 16 closer to. In this example, the distance between the inner side surface of the inner side wall surface 13 and the inner side surface of the rib 15a of the first partition wall 15 is 18 mm, and the inner side surface of the inner side wall surface 13 and the second partition wall 16 The distance between the inner surface of the rib 16a is 12 mm.

Further, the outer side wall surface 11 and the first partition 15
, Between the first partition 15 and the second partition 16, and between the second partition 16 and the inner side wall surface 13, the portion of the bottom surface 12, the U-shaped rib 11 a, Fifteen
U-shaped ribs 11b, 15b having the same shape as a, 16a,
16b is an outer side wall surface 11 and first and second partition walls 15,
16 are formed in parallel. In addition, cuts are formed on both sides of the bottom surface 12 along the outer side surfaces of the first partition 15 and the second partition 16, and the cuts are formed as thin portions 15c and 16c.

The corner member 20 is a bending member that is adjusted according to the angle of the corner of the opening, and usually forms 90 degrees. The corner member 20 has the same cross-sectional shape as the long basic member 10. That is, as is well shown in FIG. 2, the height of the outer side wall surface 21 and the inner side wall surface 23, and the first partition wall 25 and the second
The height of the partition 26 is the same as that of the basic member 10, and similar thin portions 25c and 26c are also formed. However, as will be described later, the formation positions of the male dovetail grooves 24a and 24b along the longitudinal direction formed on the back side of the inner side wall surface 23 differ depending on the manner of attachment to the rail 40 attached to the four circumferences of the opening. Come.

The corner member 20 shown in FIG. 2 is formed by cutting the above-mentioned elongated basic member 10 to a predetermined length and cutting one end face at an angle of 45 degrees with respect to the bottom surface 22. The two members 20a and 20b are formed by abutting the end surfaces cut at 45 degrees with each other.
In that case, as described above, depending on the manner of attachment to the rail 40, an operation of partially removing the male dovetail grooves 24a, 24b along the longitudinal direction formed on the back side of the inner side wall surface 23 is required. In some cases. The two members 20
The a and the 20b may be integrated by welding the abutting surfaces at the factory, or may be carried into the construction site while being separated, and may be integrated when assembled around the opening. It is a matter of course that the required corner member 20 may be manufactured by forming a special shape from the beginning.

The connecting member 30 is preferably a thin plate-shaped L-shaped member (see FIGS. 4 and 8) made by extruding aluminum. In this example, three types of large, medium and small cross-sectional dimensions are prepared. In the drawing, only one type (the largest one) is shown as an example, and its cross-sectional dimension is the U-shaped rib 11a formed on the upper end edge of the outer side wall surface 11 of the basic member 10 (corner member 20). And a U-shaped rib 1 formed on the bottom surface 12 between the outer side wall surface 11 and the first partition wall 15
1b has such a size that the upper edge 31 and the side edge 32 can be fitted.

Although not shown, the connecting member of the medium size is
The sectional dimension of the basic member 10 (corner member 20)
U-shaped rib 15a formed on the upper edge of the first partition 15
And a U-shaped rib 15b formed on the bottom surface 12 between the first partition 15 and the second partition 16 so that an upper edge and a side edge thereof can fit therein. The connecting member has a U-shaped rib 16a formed on the upper end edge of the second partition 16 of the basic member 10 (corner member 20), the second partition 16 and the inner side wall 13 And a U-shaped rib 16b formed on the bottom surface 12 between
The upper edge and the side edge are sized to fit.

In this example, the rail 40 is a thin plate-shaped long member made by extruding aluminum.
As shown in FIG. 2, the back side is a flat surface, and two male dovetail grooves 14a and 14b formed on the back side of the inner side wall surface 13 of the basic member 10 are fitted on the front side. Female dovetail grooves 41a and 41b are formed in the longitudinal direction.
A concave groove 42 is formed between the two female dovetail grooves 41a and 41b, and the concave groove 42 is provided with a stop hole 43 at a predetermined interval. Next, the aforementioned basic member 1
