Description

  The present invention relates to a building exterior accessory to be attached as a decorative rim material on a building exterior material.

In recent years, the exterior walls of buildings are often constructed using ceramic-type exterior materials.
In some cases, an architectural exterior accessory is erected and installed on the ceramics exterior material in the opening of a window or the like for makeup or rain.
Conventional building exterior accessories are long and long in the horizontal direction with a substantially rectangular cross section, and rainwater flowing along the surface of the building exterior accessories is transmitted downward as it is when the exterior exterior building features are installed. It flows along the surface of the exterior material, and traces of rainwater flow are attached to the surface of the exterior exterior building materials and ceramics exterior materials, especially when rainwater flows along with garbage etc. At the same time, there is a problem with weather resistance.

As a measure to improve this, as in the following patent document, a protrusion is provided on the surface of the exterior building accessory, and water is drained there, and a recess is provided behind the protrusion, or a groove is provided in the recess. And this draining function is improved.

However, when a large amount of rainwater flows, there is a possibility that the rainwater may be transmitted to the lower surface of the building exterior accessory along the back surface of the protrusion.
The present invention provides a building exterior accessory with a further improved draining function.

In order to solve the above problem, the invention according to claim 1 has an inclined side and a vertical side connected to the upper end, and a position substantially equal to the surface position of the vertical side at the lower end of the vertical side. It is a building exterior accessory that has a protruding piece with an apex.
According to said structure, rainwater can be cut quickly and even if a large amount of rainwater flows, transmission of rainwater below can be eliminated.

In the invention according to claim 1 , the projecting piece is composed of a projecting surface oblique side, a projecting back surface oblique side, and a projecting flat side sandwiched between both sides, and the width is narrowed toward the front diagonally downward. The exterior exterior accessory for a building has a front side recess formed between the vertical side and the projecting surface oblique side, and a back side recess formed between the projecting back oblique side and the decorative surface.
According to the above configuration, the rainwater tries to flow along the vertical side to the lower surface, but by hitting the protruding piece, the rainwater can be swept forward and obliquely downward, so a large amount of rainwater flows. However, it is possible to eliminate the transmission of rainwater downward, and no contamination is caused by the rainwater transmission.

Further, the invention according to claim 2 is the architectural exterior accessory in which the decorative surface of the architectural exterior accessory is stepped from the upper end to the lower end.
According to said structure, even if rainwater propagates in an upper end part, since a lower end part is dented in steps, rainwater is hard to be transmitted.

The building exterior accessory according to the present invention has a protruding piece having a vertex at a position substantially equal to the surface position of the vertical side at the lower end of the vertical side, so that the rainwater is quickly cut and a large amount of rainwater flows. However, the transmission of rainwater downwards can be eliminated.
The projecting piece is composed of a projecting surface oblique side, a projecting back surface oblique side, and a projecting flat side sandwiched between both sides, and has a width narrowing toward the front obliquely lower side. There is a recess on the front side, and a recess on the back side is formed between the projecting back diagonal side and the decorative surface, so rainwater tries to flow along the vertical side to the lower surface. By hitting the projecting piece, rainwater can be blown diagonally forward, so that even if a large amount of rainwater flows, it is possible to eliminate the transmission of rainwater downward, and no contamination is caused by the rainwater transmission.
In addition, the decorative surface of the building exterior accessory has a concave shape in a stepped manner from the upper end to the lower end, so even if rainwater is transmitted through the upper end, the lower end is recessed in a stepped shape. Rainwater is not easily transmitted.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view of a building exterior accessory according to the present invention, and FIG. 2 is a perspective view.
The building exterior accessory 1 of the present invention is manufactured by, for example, extruding a ceramic material.
The upper end of the building exterior accessory 1 is provided with an inclined side 2 that is inclined obliquely forward and downward, a vertical side 3 that extends vertically downward from the inclined side 2, and a protruding piece 4 at the lower end of the vertical side 3. The projecting piece 4 is composed of a projecting surface oblique side 41, a projecting back surface oblique side 43, and a projecting flat side 42 sandwiched between both sides, and the angle α of the projecting surface oblique side 41 with respect to the surface position R of the vertical side 3 is the projecting back surface. The oblique side 43 has an acute angle than the angle β with respect to the surface position R of the vertical side 3, and the width becomes narrower toward the lower front side. (See Figure 4)
A front side recess 44 is formed between the vertical side 3 and the projecting surface oblique side 41, and a back side recess 45 is formed between the projecting back oblique side 43 and the decorative surface 5.
The apex portions of the projecting surface oblique side 41 and the projecting flat side 42 of the projecting piece 4 are substantially at the same position as the surface position R of the vertical side 3. (See Figure 4)
The decorative surface 5 below the projecting piece 4 is provided with a concave shape that is sequentially recessed backward in a stepped manner, 51 is a first stepped recess, 52 is a second stepped recess, and 53 is a third stepped recess. , 54 are fourth step-like recesses.
Further, a back-cut portion 6 is appropriately provided on the back side of the building exterior accessory 1.
Here, the front refers to the direction toward the front side of the architectural exterior accessory, and the rear refers to the direction toward the back side of the architectural exterior accessory.

Then, as shown in FIG. 3, the building exterior accessory 1 is constructed around the opening.
101 is a ceramic exterior material, 102 is a vertical trunk edge, 103 is a horizontal trunk edge, 104 is a sash, 105 is a backup material, 106 is a sealing material, and 107 is a nail.

  When it rains and rainwater is transmitted along the surface of the ceramics-type exterior material 101, first, rainwater is transmitted to the inclined side 2 at the upper end of the building exterior accessory 1, and then rainwater is transmitted to the vertical side 3. And the drainage of the rainwater is performed by the protruding piece 4.

Here, the draining mechanism of the protruding piece 4 will be described in more detail.
First, when a small amount of rainwater W flows, the rainwater W that has traveled along the vertical side 3 flows along the surface-side concave portion 44 as it is, and proceeds along the protruding surface oblique side 41.
At this time, the projecting surface diagonal side 41 is directed diagonally forward and downward, and therefore rainwater W falls along the projecting surface diagonal side 41 diagonally forward and downward.
Here, since the protruding flat side 42 that is horizontal from the protruding surface oblique side 41 toward the rear is formed, the rain water W is prevented from flowing into the back surface side recess 45 due to surface tension.
If there is no projecting flat side 42, there is a risk that the rainwater W may enter the back side recess 45 due to surface tension. (See Figure 5)

In addition, when a large amount of rainwater flows, the rainwater that has traveled along the vertical side 3 flows over the surface-side recess 44 rather than along the surface-side recess 44, and the rainwater is once drained.
Then, it falls down vertically as it is. At this time, the apex positions of the projecting surface oblique side 41 and the projecting flat side 42 of the projecting piece 4 are substantially the same as the surface position R of the vertical side 3. Even if it tries to return to the rear by surface tension, it hits the projecting surface diagonal side 41 and is therefore flipped diagonally forward and downward.
As a result, it is possible to eliminate the transmission of rainwater downward, and no contamination is caused by the transmission of rainwater.

Here, the angle α of the projecting surface oblique side 41 with respect to the surface position of the vertical side 3 is more acute than the angle β with respect to the surface position of the projecting back oblique side 43.
Specifically, the angle α is desirably 15 to 30 °, and the angle β is desirably 50 to 65 °.
If the angle α is less than 15 °, draining at one end when a large amount of rainwater flows becomes impossible, and if it is larger than 30 °, the rainwater tends to accumulate and it becomes difficult to blow off.
Further, if the angle β is less than 50 °, the width of the protruding piece 4 may be narrowed and the protruding piece 4 may be chipped. If the angle β is larger than 65 °, the rain water may wrap around the back side recess 45. Comes out.

FIG. 6 shows another embodiment of the present invention. The exterior exterior accessory 10 for a building has a stepped shape on the decorative surface that is convex from the middle.
The effect is the same as that of Example 1.

FIG. 7 shows still another embodiment of the present invention. The building exterior accessory 20 has a curtain plate shape without a back-out portion and a long lower end portion.
The effect is the same as that of Example 1.

FIG. 8 shows still another embodiment of the present invention. The architectural exterior accessory 30 does not have a stepped shape on the decorative surface.
The effect is the same as that of Example 1.

  The building exterior accessory of the present invention can shed rain water forward and obliquely downward with a protruding piece, so not only around the opening, but also on the curtain plate part and nasal cover etc. Can be used.
