Description

  The present invention relates to a gutter joint that can connect eaves and eaves without impairing aesthetics.

  Conventionally, when connecting eaves to each other at right angles, an L-shaped bent joint with eaves connection parts provided at both ends is used, and the ends of the eaves are inside the eaves connection parts at both ends. Each part was inserted and connected (Patent Document 1).

  However, when the eaves and the eaves are connected via such a bent joint, the bent joint bulges outside the eaves by an amount corresponding to the thickness of the bent joint, resulting in a problem that the appearance is impaired. Such a problem cannot be neglected in view of the trend of emphasizing the appearance of houses in recent years.

  On the other hand, one end of the rain gutter in the longitudinal direction is recessed by the thickness of the inside of the gutter groove to form a reduced diameter portion, and the other end in the longitudinal direction of the other gutter is fitted into this reduced diameter portion. A rain gutter joint structure has been proposed in which an inner joint member is attached to the inner side surface of a gutter groove along the gutter seam and covering the seam in the gutter groove (Patent Document 2). ).

  In this rain gutter joint structure, the rain gutter and rain gutter are flush with each other when the other rain gutter is fitted to the reduced diameter part of the gutter that is recessed by the thickness of one gutter. The problem of losing aesthetics due to this step can be solved.

However, the above rain gutter joint structure has a problem that the cost of manufacturing this rain gutter becomes high because one gutter can be connected only if the diameter-reduced portion is formed at one end in the longitudinal direction. . In addition, when such a connection structure is adopted, in the inner ear type eaves in which the ears are formed in the eaves inner side direction, which has been widely used in recent years, the other eaves are arranged at the reduced diameter part of one eaves. When fitting the end portions of the heel, there is a problem that the inner ear portion interferes with the connection and is difficult to connect. Therefore, in Patent Document 2, the reduced diameter portion is not provided at a height where the inner ear portion of the eaves is located. This facilitates the connection work. However, if the inner joint member is not attached to the inner side surface of the concave groove portion, the gap formed between the ear portions of both connected rain gutters is noticeable. Therefore, it is difficult to reduce the labor and cost of construction by omitting the inner joint member. In addition, the rain gutter joint structure described above has a problem that the rain gutter and the gutter cannot be connected at a right angle at the corner of the roof.

It is preferable that the piece has the same height as the front plate portion of the joint body. And
The width of the projection piece is preferably 5 to 20 mm, and an engagement ear edge for engaging the ear part of the eaves hook is formed at the fitting step part, and the projection piece for concealing the gap is formed on the engagement ear edge. It is preferable to be erected. Furthermore, it is also preferable that a packing fitting groove is formed on the outer surface of the fitting step portion. Moreover, in the saddle joint of the present invention, the joint body may be bent at a right angle.

  The scissor joint of the present invention is configured to connect both the eaves to the outer surface of the joint body in a good manner by fitting the ends of the eaves to the fitting step portions formed at both ends of the joint body. In addition, the projection piece for concealing the gap provided inside the boundary between the joint body and the mating stepped portion allows the gap between the end of the joint body above the mating stepped portion and the eaves edge portion. Since the gap formed in is covered from the inside (back) and the gap is not conspicuous even when viewed from the outside (front), the appearance is good. As described above, the saddle joint of the present invention does not need to be attached to the inside corresponding to a conventional inner joint member, so that the workability is greatly improved and the construction cost can be reduced.

  Further, the fitting step is provided lower than the front plate portion and the rear plate portion of the joint body, and the projection piece for concealing the gap provided inside the boundary between the joint body and the fitting step portion is provided in front of the joint body. The joint with the same height as the plate part can be connected without interfering with the front and rear ears of the eaves, and the gap concealment formed at the same height as the front plate part of the joint body The projection piece for surely hides the gap between the eaves joint and the eaves and makes it inconspicuous.

  Moreover, the flange joint whose width of the projection piece is 5 to 20 mm is not wider than necessary, and is generated between the end portion above the fitting step portion of the joint body and the eaves edge portion. Since the width is sufficient to cover the gap from behind, the gap can be reliably hidden, and the amount of resin used can be saved.

  In addition, an engagement ear edge that engages an ear part of the eaves rod is formed in the fitting step portion, and the hook joint in which a protrusion piece for concealing a gap is erected on the engagement ear edge is formed by the engagement ear edge. By engaging the edge portion of the eaves rod with the edge, the fitting connection between the eave rod and the fitting step portion of the flange joint becomes stronger, and the protruding piece standing on the engagement ear edge Since it is located just behind the gap formed between the end portion above the fitting step portion of the joint body and the eaves, it is possible to reliably hide the gap and improve the appearance.

  In addition, the heel joint with a packing fitting groove formed on the outer surface of the mating stepped portion improves watertightness by fitting and connecting the eave ridge end portion by fitting a waterproof packing into the packing fitting groove during construction. It is possible to prevent water leakage from the connection point.

  In addition, the saddle joint in which the joint body is bent at a right angle can be arranged as a so-called bent joint at the corner of the roof, and the eaves can be connected to the eaves at a right angle.
