Description

[Detailed Description of the Invention] The present invention relates to an eaves gutter formed by covering both the front and back sides of a metal core with synthetic resin layers.

BACKGROUND ART Eaves gutters in which a metal core is embedded in a synthetic resin material have been known, and eaves gutters in which the metal core is made of a metal plate such as expanded metal or punched metal are also known. However, in the case of the former metal core made entirely of expanded metal,
Although it is possible to manufacture the product at a low cost by effectively utilizing metal materials, since it is an expanded metal, stress concentration tends to occur in the mesh part when cutting with scissors.
For this reason, cracks and other cracks are more likely to occur in the mesh portion than in the mesh portion, particularly at the upper edge of the eaves gutter where a large cutting force is applied when cutting with scissors.
In addition, in the case where the latter metal core is entirely made of punched metal, the width of the metal core to form the gutter shape is approximately equal to the expanded width of the eaves gutter, so even if the weight can be reduced by punching, Metal materials could not be used effectively, and they could not be manufactured at a lower cost than expanded materials.

The present invention has been devised in view of the above points, and will be explained below based on the drawings shown as embodiments thereof.

FIG. 1 is a perspective view of an embodiment of the present invention, and in the figure, A is an eaves gutter, 1 is an eave gutter core, 2 is a punching part, 3 is an expanded part, 4 is a synthetic resin layer, and 5 is an eaves gutter core. The gutter ear portion 6 is an eave gutter gutter-like portion. The eaves gutter A has a synthetic resin layer 4 coated on both the front and back surfaces of an eaves gutter core 1 made of a metal strip. The eave gutter core 1 has punching parts 2, 2 formed by punching holes in the longitudinal direction at both ends of a metal strip, and a longitudinal hole in the part of the metal strip between the two punching parts 2, 2. A mesh-like expanded portion 3 is formed in all directions.
Then, the punched parts 2, 2 of this eaves gutter core 1 are formed into ears at the upper edge of the eaves gutter, and the expanded parts 3 are formed into a gutter-like part, and the eave gutter core 1 formed in the eaves gutter shape is formed. Both the front and back surfaces are coated with a synthetic resin layer 4. That is, in the hole of the punched part 2 and the mesh part of the expanded part 3, the covering synthetic resin layer 4 on both the front and back surfaces is integrated, making it difficult to peel off and providing a strong coating. In the part of the punching part 2 to be buried in the ear part 5 of the eaves gutter A, stress concentration is less likely to occur as in the expanded part 3, so that cracks are less likely to occur and cracks are less likely to occur. Also, eaves gutter A
Due to the expanded part 3 to be buried in the eave gutter gutter-like part 6, the eave gutter core body 1 can be reduced in number and can be manufactured at low cost.

FIG. 2 is a partially enlarged view of another embodiment of the eaves gutter A of the present invention. The punching part 2 of the eave gutter core 1 is embedded in the ear part 5 in the inner wall of the ear part, and may be buried in the outer wall of the ear part as shown in FIG.

In the eaves gutter of the present invention, holes are formed in the longitudinal direction on both sides of a metal strip to form a punched part, and the metal strip between both punched parts is made into a mesh-like expanded part in the longitudinal direction. Both punching parts are formed into ears at the upper edge of the eaves gutter and the expanded part is formed into a gutter-like part to form the eave gutter core, and both the front and back sides of the eaves gutter core are coated with a synthetic resin layer, so that the eaves gutter can be expanded. It can be manufactured at a low cost depending on the part, and moreover, it is less likely to cause cracks or other cracks in the ear part.

[Brief explanation of the drawing]

Fig. 1 is a perspective view showing a state in which a part of the eave gutter core body is exposed in one embodiment of the present invention, and Fig. 2 is a partially enlarged perspective view of another embodiment. , 1 is an eave gutter core body, 2 is a punching part, 3 is an expanded part, 4 is a synthetic resin layer, 5 is an eave gutter ear part, and 6 is an eave gutter gutter-like part.

Claims (1)

[Scope of utility model registration request] Holes are bored in the longitudinal direction on both sides of the metal strip to form a punched part, and the metal strip between both punched parts is made into a mesh-like expanded part in the longitudinal direction, and both punched parts are placed above the eaves gutter. An eaves gutter formed by forming an edge part and an expanded part into a gutter-like part to form an eaves gutter core body, and covering both the front and back sides of the eaves gutter core body with a synthetic resin layer.
