BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bend cap at an air supply / exhaust port on an outer wall of a building.

[0002]

2. Description of the Related Art In recent years, the number of buildings whose outer walls are tiled has increased, and it has become indispensable to attach air intakes required for air supply and exhaust to these outer walls. As a commonly used method, a commercially available bend cap (air inlet / outlet) is attached to the finished surface of the outer wall and introduced into the room by a duct.

FIG. 5 shows an example thereof. In the figure, reference numeral 1 is an outer wall of a building, and a through hole 2 is formed by inserting a sleeve for duct penetration at the time of constructing a body. The end of the duct 3 is housed in the through hole 2, and a waterproof mortar 4 is filled in the gap between the periphery of the duct 3 and the through hole 2.

In the figure, reference numeral 5 is a commercially available bend cap, which comprises a joint portion 6 fitted into the end of the duct 3 and a hood portion 7 joined to the joint portion 6. In this example, the hood portion 7 has an opening for insect repellent. An opening / closing lid 9 having a net body 8 is provided. Then, a backup material 10 is interposed between the end of the waterproof mortar 4 and the mounting portion of the bend cap 5 for caulking.
Filling with 11.

The bend cap 5 includes, in addition to the one shown in the figure, a gutter-like one provided with a body slit, and the hood portion is almost circular.

[0006]

However, the construction error between the opening of the through hole 2 by the sleeve and the tile joint on the surface of the outer wall 1 is only a margin of penetration, and it is difficult to align the tile joint. Further, the conventional bend cap has no problem in exhaust, but there is a problem that rainwater will infiltrate if the diameter becomes large when used for air supply. Further, in terms of design, many designers think that the round shape of the hood portion 7 does not fit into the square tile, and the use is often limited.

The object of the present invention is to eliminate the disadvantages of the above-mentioned conventional example, to adjust the working error with the through hole by the sleeve, to be suitable for supplying a large amount of air, and to be fitted to a square tile in design. To provide a bend cap at the air supply / exhaust port of the outer wall of the building.

In order to achieve the above-mentioned object, the present invention comprises a box-shaped cover body having a rear surface as an open surface and an air circulation opening on a side surface or a lower surface, and a rectangular honeycomb rectifying portion fitted into the cover body from the rear surface side. A honeycomb straightening plate with a mounting flange attached to the outer wall of the building at the edge, and a flange that overlaps the mounting flange around the tip opening, and the bottom of the rear opening is closed to form a water baffle. The gist of the present invention is that it is composed of a connecting cylinder that is fitted in.

[0009]

According to the present invention, the position of the connecting cylinder can absorb the construction error to some extent by adjusting the diameter of the through hole by the sleeve and the diameter of the duct accommodated in the through hole, and the honeycomb straightening plate can be made by the water return of the connecting cylinder. It prevents the ingress water from the water from going further and discharges it to the outside. Further, in the honeycomb straightening plate, the flow of air is made uniform at the honeycomb straightening portion, and the surface wind speed is suppressed. It also acts as an insect repellent. Further, even in the honeycomb straightening plate portion, the tile joint error in the accommodation of the through hole and the bend cap by the sleeve can be absorbed.

Since the cover body exposed to the outside has a box-shaped rectangular shape, it matches a square tile, and since this cover body has air circulation openings on the side surface and the lower surface, it does not project greatly to the front.

[0011]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is an exploded perspective view of a bend cap at an air supply / exhaust port of a building outer wall of the present invention, FIG. 2 is a partially cutaway side view of the same as above, and FIG. 3 is a partially cutaway front view of the main part. The same components as those in FIG. 5 showing the conventional example are designated by the same reference numerals.

That is, reference numeral 1 in the drawing denotes an outer wall of a building, and a through hole 2 is formed by inserting a sleeve for passing through a duct at the time of constructing a skeleton. The point that the waterproof mortar 4 is filled in the gap between the same and 3 is the same as the conventional example.

The bend cap 12 of the present invention comprises a combination of a connecting cylinder 13 fitted at the end of the duct 3, a honeycomb straightening plate 14 and a cover body 15.

First, the cover body 15 will be described. This is a box type, the rear surface of which is an open surface 16, and air circulation openings 17 are provided on the side surface and the lower surface.

The honeycomb straightening plate 14 has a rectangular honeycomb straightening part 18 which is inserted and fitted into the cover body 15 from the open surface 16 as a main part, and the honeycomb straightening part 18 has a rear end edge to the outer wall 1 of the building. The mounting flange 19 is extended. An aluminum alloy is suitable as a material for the cover body 15 and the honeycomb straightening plate 14, and the honeycomb straightening portion 18 is formed by housing an aluminum hamicam panel inside the frame, and also the cover body.
15 is a melamine baking coating, and is colored to match the tile as described later.

The connecting cylinder 13 is provided with a flange 20 around the opening at the front end, which overlaps the mounting flange 19 of the honeycomb straightening plate 14, and a lower part of the rear end opening is closed to form a water return 21. Further, ribs 22 are provided on the outer periphery for improving the degree of joining with the duct 3.

Next, the mounting method will be described. As in the conventional case, the backup material 10 is interposed between the end of the waterproof mortar 4 and the mounting portion of the bend cap 12, and the connecting cylinder 13
Is fitted into the end of the duct 3 and its flange 20 is brought into contact with the surface of the outer wall 1 around the through hole 2. After doing this,
As shown in FIG. 3, a mounting flange 19 is superposed on the flange 20, and a base material 23 is provided around the flange 20 to fix the mounting flange 19 to the outer wall 1 with screws or the like.

In this way, the honeycomb straightening plate 14 is attached to the outer wall 1.
After mounting on the surface, the cover body 15 is fitted to the honeycomb rectifying portion 18 of the honeycomb rectifying plate 14, and the both are fixed with screws or the like.

As shown in FIG. 4, a square tile 25 is attached to the surface of the outer wall 1 via a mortar base 24, but as can be seen in FIG. 2, the cover body 15 projects beyond the opening of the through hole 2. The joint between the cover body 15 and the corner tile 25 is filled with caulking 11. This caulking 11 is a honeycomb straightening plate
It also serves as a blind for the screwing portion of the mounting flange 19 of 14. Especially, by adjusting the mounting position of the honeycomb straightening plate 14, the through hole 2 and the bend cap formed by the sleeve are adjusted.
It is possible to absorb the joint error of tile 25 in the 12-set.

[0020]

As described above, the bend cap at the air supply / exhaust port of the building outer wall of the present invention can adjust the construction error with the through hole by the sleeve, and also prevents rainwater from entering and wind flow. It is suitable for supplying a large amount of air since the surface wind speed is made uniform by controlling the air flow rate, and it is also designed to fit square tiles.
