Description

  The present invention relates to an eaves joint structure for connecting eaves by sandwiching an end of the eaves with an outer joint and an inner presser.

Conventionally, the longitudinal ends of a pair of eaves ridges are opposed to each other, and an outer joint is fitted on the outer side surface of the eaves ridges, and an inner presser is fitted along the inner surface between the end portions. It is practiced to connect the eaves by sandwiching the end of the eaves with the outer joint and the inner retainer. Specific examples are disclosed in Japanese Patent Application Laid-Open Nos. 11-044060 and 9-144242.

  However, the eaves joint structure of the above specific example has the following problems. Rainwater flows into the gap between the outer joint and the lower holding piece of the inner retainer and accumulates in the gap. The joint portion gets wet with rainwater due to the surface tension of the rainwater, and part of the rainwater may overflow outside the eaves. there were. In this case, after the moisture in the eaves is dried, foreign matters such as dust contained in the rainwater may adhere to the outside of the joint portion, which may impair the appearance.

  The present invention has been made in view of such a reason, and its purpose is to prevent the eaves from overflowing outside the eaves even if rainwater flows into the gap between the outer joint and the lower presser piece of the inner presser. It is to provide a joint structure.

  In order to solve the above-described problem, the eaves joint structure of the present invention has a pair of eaves ridges facing each other in the longitudinal direction, and an outer joint is fitted on the outer side surface of the eaves ridge, and ends In the eaves joint structure that connects a pair of eaves by fitting the inner retainers along the inner surface between the parts and sandwiching the eaves with the outer joint and the inner retainer, A drain hole is drilled in the lower presser piece of the inner presser along the direction.

  Since the eaves joint structure of the present invention has a drain hole formed in the lower holding piece, even if rain water flows into the gap between the outer joint and the lower holding piece, the rain water is discharged from the drain hole. There is no risk of rainwater overflowing outside the eaves.

  The eaves joint structure of this embodiment is demonstrated based on FIGS. As shown in FIG. 1, the eaves bar joint structure of the present embodiment is connected by sandwiching a pair of eaves bar 1 by an outer joint 6 and an inner presser 7.

  The eaves 1 is formed by coating a synthetic resin material on both surfaces of a metal plate such as a steel plate. The front plate 3 is formed of a front upper portion and a front lower portion. The front lower portion is inclined so as to rise from the front end of the bottom plate 2 and go forward, and the upper front portion goes upward. As it tilts backwards. Further, a continuous piece is formed obliquely downward from the upper end of the upper front surface, a front ear portion is provided in the longitudinal direction at the tip of the continuous piece, and a locking step portion is provided on the front ear portion. A groove 3a, which is a drainage groove recessed inward from the outer surface, is provided in the longitudinal direction on the upper lower end of the front surface, and a draining projection is suspended so as to project downward from the lower lower end of the front surface. . A rear ear portion is provided at the upper end of the rear plate 4.

  The eaves 1 and 1 are connected in a straight line by an outer joint 6 and an inner retainer 7 formed of a synthetic resin material. The outer joint 6 is formed on the outer joint front plate 6b raised from the bottom plate 6a so as to be along the front plate 3 of the eaves 1 and is recessed inward, that is, toward the series of grooves 3a of the eaves 1. The submerged second groove 6d is provided over the width direction of the joint. As shown in FIG. 3, the second groove 6 d goes from the center portion to both edges in the width direction so that water drops flowing down the outer peripheral surface of the outer joint front plate 6 b are reliably guided to the groove 3 a of the eaves bowl 1. Accordingly, an opening is formed toward the groove 3a. And the notch 6e and 6e which notched the bottom face are provided in the edge of the 2nd groove | channel 6d. Further, a front ear pressing portion 6f that engages with the locking step portion when the eaves rod 1 is connected is provided at the edge of the outer joint front plate 6b. Separator protrusions 6g are respectively provided in the vicinity of the center in the width direction of the inner surfaces of the outer joint front plate 6b and the outer joint rear plate 6c of the outer joint 6, and at the edge of the outer joint rear plate 6c. A rear ear pressing portion 6h that is engaged with the locking step portion when connecting is provided.

  The inner presser 7 includes a bottom presser piece 7a, a front presser piece 7b bent from the bottom presser piece 7a, and a rear presser piece 7c so as to extend substantially along the inner peripheral surface of the joint of the eaves rod 1. The bottom presser piece 7 a and the rear presser piece 7 c are formed in a shape along the bottom plate 2 and the rear plate 4 of the eaves 1. Further, a lower pressing piece 7d extending along the lower inner surface of the front plate 3 of the eaves 1 from the lower end of the front pressing piece 7b is integrally extended upward. The lower pressing piece 7d is provided with a pair of adhesive grooves 7e, 7e for disposing an adhesive for fixing the outer joint 6, and two water grooves are provided between the adhesive grooves 7e, 7e. Holes 7f and 7f are formed. And the operation piece 7g is provided in the upper part of the front pressing piece 7b.

  When the eaves 1 and 1 are connected by the eaves-and-eave joint structure of the eaves, first, the rear ears provided at the edge of the rear plate 4 at the longitudinal ends of the connected eaves 1 and 1 are connected. After engaging the rear ear pressing portion 6h of the edge of the outer joint rear plate 6c with the outer part, it is wound around the locking step provided in parallel with the front ear provided at the edge of the front plate 3 The front ear pressing portion 6f at the edge of the outer joint front plate 6b is engaged and fitted. Next, an adhesive is disposed in the adhesive grooves 7e and 7e of the inner presser 7, and the operation piece 7e is held in a state where the upper end of the rear presser piece 7c is engaged with the lower surface of the rear ear part. Then, the front side of the inner presser 7 is rotated downward, and the eaves rods 1 and 1 are moved from the inner peripheral surface to the outer joint 6 so that the groove 3a of the eaves rod 1 is surely opposed to the second groove 6d at the edge. Wear it so that it is pressed. In this state, the outer joint 6 and the inner presser 7 are securely fixed by curing the adhesive.

  When rainwater flows into the eaves joint structure portion of the eaves from a roof or the like, the rainwater also flows into the gap between the outer joint front plate 6b and the lower presser piece 7d of the inner presser 7. However, rainwater that has flowed into the gap flows from the direction of the arrow shown in FIG. 3B to the inside of the inner presser 7 through the drain hole 7f. For this reason, rainwater is smoothly discharged into the inner presser 7 without accumulating in the gap between the outer joint front plate 6b and the lower presser piece 7d.

  The eaves joint structure of the present embodiment has a drain hole formed in the lower presser piece of the inner presser, so even if rainwater flows into the gap between the outer joint front plate and the lower presser piece, Since rainwater is discharged from the drain hole by being smoothly discharged into the inner presser without being accumulated in the gap between the face plate and the lower presser piece, there is no possibility of rainwater overflowing outside the eaves. As a result, after the moisture in the eaves is dried, foreign matters such as dust contained in rainwater adhere to the outside of the joint portion, so that there is no risk of damaging the appearance.

  In addition, since the drain hole is formed between the adhesive grooves of the lower pressing piece, it is possible to drain rainwater in a portion that tends to accumulate, and the effect can be further improved. .

  Furthermore, since a plurality of drain holes are formed, rainwater can be discharged from other drain holes even when one drain hole is blocked by a foreign substance. Therefore, the effect can be further ensured.
