Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a metal eaves gutter made of a bent copper plate or the like.

(Conventional technology and problems) Eaves gutters installed at the eaves catch rainwater flowing down from the roof and direct it to a water collector, but the inner surface of these eaves gutters collects sand, acid rain, etc. that falls with the rainwater. Because of this, the damage is significant.

When used for a long period of time, the parts where rainwater falls tend to get damaged quickly, and metal eaves gutters are susceptible to the effects of acid rain in urban areas. There was also the fear of holes being made in the gutters.

Conventionally, a countermeasure against this problem was to apply resin paint such as acrylic paint to the inner surface of the eaves gutters.
Due to the weather resistance of the paint, it could not withstand long-term use, and it was not possible to achieve sufficient effects.

Furthermore, in the case of metal eaves gutters, if paint is applied to the inner surface, it is difficult to solder the gutter.

(Purpose of the invention) This invention was devised in response to the above-mentioned problems, and it strengthens the inner surface of the eaves gutters by coating them with a fluorocarbon resin paint with excellent weather resistance, and also strengthens the inner surfaces of the eaves gutters. The metal eaves gutter is easy to install by applying fluororesin except for the parts that require soldering or adhesives for connection.

(Structure of the invention) The present invention will be explained in detail below based on an embodiment shown in the accompanying drawings.

Fig. 1 shows a perspective view with the middle part of the eaves gutter 1 omitted, but the eave gutter 1 is made by bending a thin metal plate such as a copper plate, and the main body 11, which is approximately U-shaped, has a cylindrical shape at both upper ends. Ear portions 12, 12 are formed.

The length of this eaves gutter 1 is about 1.8 m to 3.6 m, and at one end in the longitudinal direction there is a tongue-shaped overlapping piece 13.
is extended, and connection rods 14, 14 are formed to protrude from the ears.

A fluororesin paint 2 is applied to the inner surface of the main body 11 of such an eaves gutter 1, but it is not applied to the entire inner circumferential surface but is applied to the edges 15, 15 in the longitudinal direction of the main body 11.

The width of this edge 15 is such that when the eaves gutters 1 are overlapped to connect them, the metal part of the main body 11 comes out as shown in the perspective view of FIG. 2, and is a place where soldering or adhesive is applied. The amount is such that the two parts of the fluororesin do not overlap.

Also, in the direction across the eaves gutter 1, it is possible to apply the coating up to the upper end of the main body 11 as in this embodiment.
The effect can be achieved even if it is applied only to the center of the bottom, which is particularly prone to damage.

Figure 3 shows a cross-sectional view of the main parts when such eaves gutters 1 are connected, but it can be ensured by connecting and fixing the edges 15, 15, which are not coated with fluororesin 2, with solder 3. It can be constructed in

(Effects of the invention) As mentioned above, the metal eaves gutters according to the invention are coated with a highly weather-resistant fluororesin paint on the inner surface, so unlike conventional acrylic resin paints, they last for a long time. It can be used without causing any damage to the eaves gutters, and since no coating is applied to the connecting parts during construction, the connection work is no different from conventional methods, and can be easily and reliably constructed.
