Description

  The present invention relates to an eaves joint that connects ends of opposing eaves. More particularly, the present invention relates to an eaves joint that connects the ends of eaves to prevent leakage of water flowing in the eaves due to rain, snow, or the like.

  When connecting eaves eaves, a construction method is adopted in which eaves eaves joints are interposed at opposite ends of eave eaves.

  That is, by fitting an eaves joint that matches the inner surface shape of the eaves to the inner surface of the connecting part of the eaves, and fixing them together, the shape continuity at the connecting part of the eaves is maintained, thereby connecting Water leakage in the area is prevented (water stoppage).

  Such an eaves joint, for example, as shown in FIG. 3, the upper end of the front wall 51 and the upper end of the rear wall 52 are respectively connected to the front ear portion 32 and the rear ear portion 34 of the eaves ridge 30. By engaging, the inner surface of the connecting portion of the eaves rod 30 is fitted. At this time, the eaves rod joint 50 is pressed against the eaves rod 30 by the pressing force indicated by the arrow in the drawing and is brought into close contact therewith.

  However, as shown in FIG. 3, the force that presses the eaves joint 50 against the eaves 30 is limited in the downward direction, and therefore, the eaves inner side corner 35 that is an important point for water stop (water stop important part). The pressing force against is insufficient.

In Patent Document 1, as shown in FIG. 4, a joint main body 61 fitted to the inner surface of the connecting portion of the eaves rod 30 and a reinforcing joint for pressing the joint main body 61 against the inner surface of the connecting portion of the eaves rod 30. An eaves joint 60 comprising a member 62 is disclosed. In the case of the eaves joint 60 of this Patent Document 1, the joint body 61 is more strongly pressed against the eaves 30 by the pressing force of the reinforcing joint member 62, and in particular, an adhesive between the eaves 30 and the joint body 61 is applied. It has the advantage of improving the adhesion between the two by diffusion. However, since the pressing force of the reinforcing joint member 62 against the joint body 61 is downward and horizontal as indicated by the arrows, the pressing force against the eaves inner corner 35 which is an important part of the water stop is also downward and horizontal. The effective pressing force is not applied.

  As described above, it is necessary to further improve the adhesion between the eaves and the eaves joint, in order to improve the water-stopping performance of the eaves joint. It is important to give an effective pressing force to it.

  The present invention has been made in view of the circumstances as described above, and applies an equal pressing force to the inner surface of the eaves so as to be effective also for the apex of the eaves inner side corner which is a water stop important part. An object of the present invention is to provide an eaves joint that gives a pressing force.

The present invention, in order to solve the above problems, an eaves gutter joint for connecting the ends of the opposing eaves gutters, a substantially square tubular shape of the first joint abutting fitted in eaves gutters inside, consists of a second coupling for engaging to pressed against the upper surface of the first joint, the first joint has a front wall, rear wall, lower wall and a concave curved surface of the upper, the said rear wall An engagement piece that protrudes inwardly directly above the joint with the concave curved surface and is substantially parallel to the inclination of the curved line of the concave curved surface at the contact point between the concave curved surface and the rear wall, The joint has a concave pressing portion having substantially the same curved surface shape as the concave curved surface of the first joint, and the second joint is disposed in a gap between the concave curved surface of the first joint and the engagement piece. the rear end portion is inserted in to the concave curved surface of the first joint, the concave pressing portion of the second joint is pressed against the second splicing Pressing force is characterized by extending the contact surfaces throughout the said first joint and eaves gutters.

  According to the first aspect of the invention, since the contact surface of the first joint with the second joint is a concave curved surface, a radial pressing force is generated, and the eaves inner side corner which is a water stop important part is formed. On the other hand, it is possible to effectively apply a pressing force, and it is possible to improve the water stoppage.

  FIG. 1 is a cross-sectional view showing an embodiment of the eaves joint according to the present invention, and shows a process of attaching the eaves joint 1 (first joint 10, second joint 20) to the eaves joint 30.

  The eaves bowl 30 has an eaves bowl front ear part 32 at the upper end of the eaves bowl front wall 31 and an eaves bowl rear ear part 34 at the tip of the eaves bowl rear wall 33. In particular, the eaves hook front ear 32 is provided at the upper end of an eaves front wall 31 that is bent inward of the eaves 30.

  The first joint 10 forms a substantially rectangular cylindrical structure by the front wall 11, the rear wall 12, the lower wall 13, and the upper concave curved surface 14. The concave curved surface 14 is joined to the upper end of the front wall 11 from the middle of the rear wall 12. An engagement piece 15 protruding inward is provided immediately above the joint between the rear wall 12 and the concave curved surface 14. The engagement piece 15 is disposed substantially parallel to the inclination of the curve line of the concave curved surface 14 at the contact point between the concave curved surface 14 and the rear wall 12. The concave curved surface 14 and the stepped portion 16 of the lower wall 13 are connected by a connecting member 17.

  The second joint 20 has a distal end of a concave pressing portion 21 having substantially the same curved surface shape as the concave curved surface 14 of the first joint 10. And it is comprised by the neck part 22 which returns from the front-end | tip of the concave pressing part 21 to the upper back, the opening part 23 provided on the neck part 22, and the handle 24 provided on the opening part 23. FIG.

  When attaching the eaves rod joint 1 (the first joint 10 and the second joint 20) to the eaves rod 30, it can be performed as follows.

  First, an adhesive is applied to the inner surface of the eaves rod 30, and then the first joint 10 is inserted into the eaves rod 30 and rotated as indicated by the arrow A while the upper end portion of the rear wall 12 is moved to the rear edge of the eaves rod 30. The front wall 11, the rear wall 12, and the lower wall 13 are brought into contact with and fitted inside the eaves wall 30 by engaging with the portion 34 (FIG. 1 a → b).

  Subsequently, the rear end portion of the second joint 20 is inserted into the gap between the concave curved surface 14 and the engagement piece 15 as indicated by arrow B, and the concave pressing portion 21 is pressed against the concave curved surface 14 in the direction of arrow C while closely contacting. Then, the mouth portion 23 is fitted to the eaves pad front ear portion 32 (FIG. 1b → c). As a removal method, the handle 24 can be easily removed by holding the handle 24 and pushing it backward.

  Generally, the eaves is not particularly limited to a metal or a resin, and for example, a folded product of a plate material in which a synthetic resin layer is laminated on both surfaces of a metal core plate is considered. Therefore, the material of the first joint and the second joint in the present invention is not particularly limited as in the eaves, but is preferably used because the manufacturing cost can be reduced by using the same material as the eaves. Each surface and each part of the first joint and the second joint may be welded, or may be bonded or bent one plate material.

  With respect to the shape of the eaves, for example, the front wall of the eaves may be a substantially upright wall as illustrated in FIGS. 1 and 2, an inclined wall as illustrated in FIG. 3, or a curved wall. The shape of the second joint according to the shape of the eaves rib is appropriately selected, and the shape of the second joint is required so that the second joint cannot be removed by the reaction force of the pressing force. Naturally, the bottom surface may be stepped as illustrated in FIGS. 1 to 4 or may be planar, and the shape of the first joint corresponding to the eaves shape may be selected.

  The connecting member 17 that interposes the concave curved surface 14 and the lower surface wall 13 of the first joint 10 in the present invention works particularly effectively when the bottom surface of the eaves rod 30 has a stepped portion (FIGS. 1 and 2). The radial pressing force provided by the second joint 20 is applied to the step portion through the connecting member 17, and has an effect of preventing large radial deformation and preventing the radial pressing force from escaping.

  According to the present invention as described above, a pressing force is applied radially from the center point 40 of the curved approximate circle of the concave curved surface 14 of the first joint 10 by the second joint 20 as shown in FIG. A pressing force is evenly applied to the eaves inner corner 35, which is an important water-stopping part, and the adhesive spreads evenly, thereby improving the adhesion.

  Of course, the present invention is not limited to the above examples, and it goes without saying that various aspects are possible in detail.
