Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a synthetic resin exterior decorative material for buildings.

Conventional Art Conventionally, exterior decorative materials for buildings (decorative shells, decorative gables, decorative gutter covers, decorative fascias, etc.) have been made of wood and painted, colored steel plates, PVC steel plates, etc. Over the years since installation, the paint and surface materials have peeled off, exposing the underlying material and causing corrosion and rust.

Technical Problem The purpose of the present invention is to provide a decorative material for use as an exterior material for construction, which generates less dirt on its surface.

Solution The present invention is an exterior decorative material consisting of a top side 1, a side side 2, and a bottom side 3, which is made of synthetic resin. This is an exterior decorative material made of synthetic resin that is divided into a plurality of parts in the horizontal direction, and each of the divided sides recedes inward as it goes downward.

By using a synthetic resin extrusion molded body instead of wood or steel plate, the present inventors obtained an integrally molded body with no peeling of paint or surface material, and obtained an exterior decorative material that does not cause corrosion or rust. was successful. In addition, extrusion molded products are suitable for use as exterior decorative materials because long products with the same cross-sectional shape can be manufactured. Furthermore, it is also possible to reduce the weight of the molded product by using a low-foaming synthetic resin extrusion molded product consisting of an unfoamed outer shell on the surface and a foamed resin on the inner surface.

A synthetic resin low-foaming extrusion molded product can be obtained by adding a foaming agent, coloring material, etc. to a synthetic resin and extruding it from an extrusion molding machine, and it has an unfoamed outer skin on the surface and a foamed resin inside. It is a molded body made of Since this foam is integrated as a whole, it can be used for a long time without peeling off the outer skin.

However, when weather resistance tests are conducted using this exterior decorative material, especially when the surface of the decorative material is light-colored, dirt in the air makes it obvious that rain has collected and flowed in areas and areas that have not flowed, making it unsightly. It turns out that

Therefore, the tip of the upper side 1 where rain collects is made to protrude from the side 2 to form a draining part 12, so that the rainwater that falls on the upper side falls directly from the side of the draining part, so that the rainwater does not get transmitted to the lower side 2. This ensures that the entire surface gets wet with almost the same amount of rain, preventing it from getting dirty due to rain flow.

A protrusion 21 may be provided on the draining portion 12 to allow rainwater to fall from the tip of the protrusion 21 to reliably prevent rainwater from being transmitted from the draining portion to the side 2.

If the height of the side 2 is large, even if the rainwater on the top side 1 is not transmitted, the rainwater will fall on the side, and if it collects and flows downward, the parts that have flowed and the parts that have not flowed will be clearly noticeable and it will be unsightly. becomes.

Therefore, the side edge 2 is divided into a plurality of parts in the height direction, and each divided side edge is made to retreat inward as it goes downward. In this way, similar to the drainage section, rainwater that falls on each divided side is allowed to fall directly from the lower end of each side, without affecting the side that is further below the side. Prevents dirt from flowing.

Grooves may be provided on the sides. By using this groove to drive a tapping screw, it is possible to make the screw difficult to see from the outside and to prevent water from entering through the screw hole.

Further, if mounting ribs 11 are provided on the upper side 1, mounting becomes easy. By using this rib, you can hook it onto a metal fitting pre-installed on an external wall, etc., or place it on a piece of wood that has been pre-installed.
A long exterior material can be reliably positioned at a predetermined position, and the exterior decorative material can be easily attached.

Example FIG. 1 shows a cross-sectional view. The outer periphery is made of a resin layer that is hardly foamed, and the inside is made of foam to reduce weight.

The exterior decorative material consists of an upper side 1, side sides 2, and lower side 3, and an attachment rib 11 is provided near the end of the upper side. In addition, as can be clearly seen in Figure 2, the upper side 1 has a slight slope, so that rainwater received on the upper side collects in the drain and flows to the side of the drain, and rainwater falls from the protrusion 21 at the lower end of the side of the drain. It's getting old.

The side edge 2 consists of a first side edge 22, a second side edge 23, and a third side edge 24, and the first side edge 22 and the second side edge 23
A first groove 25 is provided between the second side 23 and the third side 24, and a second groove 26 is provided between the second side 23 and the third side 24. The first side, second side, and third side are sequentially retreated inward from the protrusion. This is to prevent dirt from rain.

Even if the protrusion 21 is provided, if the height of the side surface is large, the parts where rain has collected and flowed and the parts where it has not flowed will be clearly noticeable, making it unsightly. Therefore, the height of the sides is subdivided to reduce the collection of rainwater.

Next, we will explain how to attach the exterior material according to the present invention.
This will be briefly explained with reference to FIGS. 2 and 3.

A plurality of short mounting hardware 41 are installed in advance on the outer wall surface 4.
are fixed with screws 45, and the mounting rib 11 is attached to the metal fitting 4 mentioned above.
Hang it on the upper part 42 of 1. Further, a color tapping screw 43 is driven into the mounting hardware 41 from the second groove 26 of the exterior decorative material. This allows the exterior material to be fixed at two locations. In addition, since a plurality of mounting hardware 41 are installed in the length direction of the exterior decorative material,
It can be securely fixed to the external wall surface.

When using the mounting wood 44, attach the mounting rib 11 on the mounting wood 44 that has been attached to the outer wall surface 4 in advance.
, and then drive the collar tapping screws 43 into the mounting wood 44 through the first groove 25 and the second groove 26.

In this way, the exterior decorative material can be fixed by hooking the ribs and driving the tapping screws through the grooves. Also, when you can reach the back side, such as when using it to hide a gutter, you can hook it on the rib and tighten it with a thumbscrew using the second groove.

Effects The exterior decorative material of the present invention is made of synthetic resin and is integrated throughout, so there is no need to worry about the surface peeling off.

The drainage part on the top side protrudes from the side edge, and the side edge is divided into height directions, and each divided side edge recedes inward as it goes downward, so the top edge and each divided side edge Rainwater falls directly from the drainage section and the side edges of each division, and does not affect the lower side edges. Therefore, even if rainwater collects and flows, it will flow directly to the lower end of the dividing side, so no dirt will be generated by the flow of rainwater.
