Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to a lower portion of a sash of a window frame of a building or a wall surface of a building such as a roof of an eave or bay window, and a portion having an inclined drainage surface through which rainwater flows down. It relates to the drainage structure.

2. Description of the Related Art In a portion having an inclined drainage surface through which rainwater flows down, such as a lower portion of a window (a lower portion of a sash), when rainwater flows down along a window portion, , Dust and dirt also run off along with rainwater, and if they reach the wall of the building and flow down, the wall becomes dirty. For this reason, a drainer structure has been adopted in which the drainage slope is projected from the wall surface. However, various improvements have been proposed on the assumption that the wall surface is not completely prevented from being contaminated by merely projecting the inclined drainage surface portion.

Specifically, Japanese Patent Laid-Open No. 9-279959 discloses means for making drainage from the front edge of the inclined drainage surface into water droplets of a certain size. Since the direction and direction of the wind are not constant, the water droplets that adhere to the wall surface after being scattered by the wind are not particularly conspicuous and do not need to be considered so much. The biggest cause of dirt on the wall surface is that dirty rainwater always flows down to the wall surface and flows down, and the downflow path is fixed, so dirt is accumulated and stands out.

As a means for solving the generation of dirt on the wall surface, drainage from the inclined drainage surface may be prevented from being transmitted to the wall surface. Therefore, a large space is formed behind the draining surface provided on the front edge of the inclined drainage surface, and a sealing (caulking) material is filled between the hanging piece after the space and the building wall surface, and the draining member is attached to the wall surface. A structure has been proposed that realizes water sealing of the wall surface (registered utility model No. 3038187).
issue).

However, since the water draining member has a space behind the water draining surface, it is possible to prevent water from being transmitted to the wall surface, but the projection distance from the wall surface becomes large, and the appearance of the building is unsightly. Further, there is a problem that the caulking work becomes an upward work and is difficult to perform.

When observing the window frame part of the existing building,
Dirt (so-called cornering) from the edge of the window frame is often noticeable.
This is because the sloped drainage surface of the drainer is a gentle sloped surface, so that it is gathered at one end by the wind, and rainwater overflows from the end and is transmitted to the wall surface and polluted.
As a countermeasure against this, it has been previously proposed to provide water stop pieces at both ends of the inclined drainage surface (Actually No. 55-180882).
issue). In addition, a method has also been proposed in which a rain stop ridge is provided on the inclined drainage surface itself to prevent the rainwater from flowing laterally (Actual Kaihei 3-47387).

However, in the former case, there is a possibility that rainwater may accumulate at the water stop piece and overflow the water stop piece due to the strength of the wind. Therefore, if the water stop piece is made large to enhance the blocking effect, the appearance is unsightly. . On the other hand, in the latter case, if the entire inclined drainage surface is formed into a concavo-convex line, the portion cannot be wiped and cleaned, and it is difficult to clean it when it becomes dirty.

Therefore, the present invention proposes a new draining structure for solving the above-mentioned problems in draining rainwater such as window frames.

[0009]

A draining structure such as a sash according to the present invention is a measure for preventing cornering, in which a tip end portion is an inclined drainage surface portion projecting outward from a wall surface of a building, and a tip end of the inclined drainage surface portion. In a water draining structure such as a sash having a water draining surface portion provided downward, a plurality of protrusions extending from the surface of the inclined drainage surface portion to the surface of the water draining surface portion are juxtaposed at appropriate intervals, and the inclined drainage surface portion side of the protrusion portion is provided. The length from the drain surface of each protrusion is sequentially changed so that the end of the drain is inclined in the left-right direction from the sash center position or in the center direction from the sash corner position toward the hem side of the drainage surface part. It is what In addition, it is characterized in that the base plate is provided with the projecting portion and is a single component.

When the rainwater on the inclined drainage surface portion is laterally flowed by the side wind, the lateral distance is blocked by each of the projecting portions due to the projecting distance of the projecting portions, and the range is defined by each projecting portion (running water groove). Dispersed in and dropped from the draining surface. In addition, if it is a single component provided with the above-mentioned protruding portion, the existing draining member and the new draining member can be subjected to cornering prevention treatment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described. The embodiment shows an example in which a draining member 1 and a corner restraint body (independent component) 2 embodying the present invention are adopted.

The draining member 1 is used continuously with a lower frame portion of a window frame (sash) A provided in a building. Like the sash A, a long extruded material is cut into a predetermined length for use. To do. And the cross-sectional shape is the inclined drainage surface portion 11, the draining surface portion 12, the back surface draining surface portion 13,
The inclined drainage surface portion 11 is provided with the sealing surface portion 14.
Is a width in which the tip portion projects outwardly from the building wall surface when connected to the lower frame front edge of the sash A and mounted on the lower surface of the wall prospective surface B (detailed conditions will be described later). ), A connecting rising portion 111 is provided on the base side (one side edge),
On the back surface, an engaging portion 112 of a metal fitting C for fixing to a building is provided.

The draining surface portion 12 is the inclined drainage surface portion 11 described above.
It is provided with a back space a which is vertically extended downward from the tip of the back end and has a height and a protrusion degree sufficient to prevent water droplets from moving toward the back surface draining surface portion 13 side.

The back side draining surface portion 13 is provided behind the draining surface portion 12 via the back space a from the lower surface of the inclined drainage surface portion 11 and is provided at a position where it abuts against the building wall surface D. is there. The sealing surface portion 14 is formed so as to protrude rearward from the lower end of the back surface draining surface portion 13.

The corner restraint 2 is formed so as to correspond to the draining member 1, and has a base plate 21 and a protrusion 2.
It consists of two. The base plate 21 is a thin plate that comes into close contact with the inclined drainage surface portion 11 and the draining surface portion 12 at the corner portion of the window frame, which is the mounting location, and the protrusion 22 extends from the portion corresponding to the inclined drainage surface portion 11 of the base plate 21 to the draining surface portion 12. A plurality of protrusions 2 which are continuous to a position corresponding to
A large number of running water grooves 23 partitioned by 2 are formed. Further, the ends of the juxtaposed protrusions 22 on the side corresponding to the inclined drainage surface part 11, that is, the mountain side ends are sequentially positioned on the far side (upper side of the mountain) toward the corner side.

Then, the draining member 1 is continued to the lower frame of the sash A arranged and fixed on the wall prospective surface B, and is screwed to the sash or fixed by the locking metal fitting C. Next, the corner sag prevention body 2 is attached, and the corner sag prevention body 2 adheres and fixes the base plate 21 to the inclined drainage surface portion 11 and the drainage surface portion 12 at the corner portion of the window frame. An adhesive is used, or tacking or screwing is adopted at the location of the draining surface portion 12.

After the water draining member 1 and the corner anti-slipping member 2 are assembled, a mortar material is filled in the space between the assembling member and the building wall D, and the sash in the water draining member 1 and the corner anti-slipping member 2 is further filled. A sealing treatment E is applied to the seam of A, the seam with the wall prospective surface B, and the seam with the wall surface D.

As described above, when the draining members 1 and the corner anti-driving member 2 are installed under the window, the rainwater b transmitted to the window flows down the inclined drainage surface portion 11 and is transmitted to the drainage surface portion to flow down to the drainage surface portion 12. Dripping from the bottom. In particular, since the space a exists on the back surface of the draining surface portion 12, the water droplet b does not reach the wall surface and flow down, thereby suppressing the generation of dirt on the wall surface. In addition, the projection length of the water draining member 1 from the wall surface D may be within the range of forming the space a, and the projection can be made smaller than the structure of the above-mentioned previous proposal (registered utility model No. 3038187). did it.

Further, even if the rainwater on the inclined drainage surface portion 11 is made to flow to the corner portion of the wall prospective surface B by the wind, due to the difference in the end positions of the adjacent protrusions 22 of the corner preventing member 2,
The height of the flowing water groove 23 divided by the protruding portion 22 on the inclined surface of the groove is different, and the rainwater is guided to and dispersed in each flowing water groove 23 according to the sequentially changing height. Drops are made from the draining surface portion 12 in a state in which the cross flow due to the wind is blocked.

The present invention is not limited to the above-described embodiment, and the draining member 1 and the corner preventing member 2 may be used independently, or may be a member having an integrated structure. .

In addition, when the neutral window F for a continuous window is adopted, a drainage portion of the sash A is often provided in the vicinity of the vertical F, and therefore, in the continuous window, similar to the cornering near the vertical direction. Easy to get dirty. Therefore, as illustrated in FIG. 6, even if the flow dividing member 2a whose central portion is located above the inclined drainage surface portion 11 and which has the protruding portions 22 which are sequentially lowered to the left and right is attached to the inclined drainage surface portion 11 of the drainer. good.
