Description

The present invention relates to a connection structure for an eaves-inner joint that connects a pair of eaves attached to the eaves of a building, and more particularly, even when the distance between the upper end of the front wall of the eaves and the tip of the roof is narrow. The present invention relates to a connection structure for an eaves-inner joint that can be easily inserted into the eaves.

  Conventionally, when connecting a pair of eaves eaves in the longitudinal direction, an adhesive is used for the eaves eaves inner joint formed by a synthetic resin material or the like with substantially the same cross-sectional shape as the eaves eaves in a state where the ends of the eaves are in contact with each other. It was glued to the inner peripheral surface of the eaves.

  However, when the distance between the upper end of the front wall of the eaves and the lower end of the roof is narrow, there has been a problem that the joint in the eaves cannot be easily inserted into the eaves.

  A method for solving this problem is disclosed in Patent Document 1. As shown in FIG. 9A, the eaves-inner joint 20 of Patent Document 1 is easily inserted into the eaves eaves 10 to connect a pair of eaves eaves 10.

  The eaves-inner joint 20 has a concave cross-sectional shape, and is attached to the front plate portion 21 attached to the front wall 11 of the eave ridge 10, the bottom plate portion 23 attached to the bottom plate 13 of the eave ridge 10, and the rear wall 12 of the eave ridge 10.

  For this reason, even when the space | interval of the upper end part 10a of the front wall 11 of the eaves ridge 10 and the front-end | tip part 3 of the roof 2 of the building 1 is narrow, the back board part 22 shall be made into an obtuse angle state with respect to the bottom board part 23, and The entire inner joint 20 can be easily put into the eaves bowl 10 while preventing it from hitting the tip 3.

  Then, with the rear plate portion 22 and the bottom plate portion 23 having an acute angle by the groove 20a, the rear plate portion 22 is in a state where the upper end portion of the rear plate portion 22 is hooked on the corner of the rear wall 12 and the rear ear 12a of the eaves rod 10. By performing the insertion operation along the rear wall 12, the entire eaves joint 20 can be easily inserted into the eaves.

  However, when the insertion operation is performed until the rear plate portion 22 extends along the rear wall 12 in a state where the upper end portion of the rear plate portion 22 is securely hooked on the corner of the rear wall 12 and the rear ear 12a, the back side of the groove 20a is The adhesive may come off in contact with the bottom plate 13. For this reason, there was a problem that the water stoppage between the eaves inner joint 20 and the eaves rod 10 could not be ensured reliably, and rainwater leaked from the connecting portion.

  In addition, the strength in the vicinity of the groove 20a is insufficient due to the groove 20a, and the eaves-inner joint 20 has a concave cross section, so that when the eaves receives an impact from the outside, the eaves-inner joint 20 and the eaves are displaced or detached. It was unstable in terms of strength.

A method for solving the problem of insufficient strength of the joint inside the eaves is disclosed in Patent Document 2. As shown in FIG. 9B, the eaves inner joint 20 of Patent Document 2 includes an outer joint 31 and an inner joint 32, and the inner joint 32 includes a reinforcing material 34. The reinforcing member 34 is detachably fitted with the first locking portion 37 and the second locking portion 38 provided at both ends thereof in the holding portion 39 and the holding portion 30 provided on both side walls 35 of the inner joint 32. It is constructed by. Since both side walls 35 of the inner joint 32 can be firmly adhered to the eaves ridge 33 by the reinforcing material 34, the eaves ridge inner joint 20 and the eaves ridge 33 are not displaced or detached.

<Operation of the eaves inner joint>
As shown in FIG. 7A, the lower member 49 is inserted into the eaves 41 from the gap G3 with the rear wall portion 52 at the head. Here, the relationship between the maximum insertion width G4 of the bottom wall portion 53 of the lower member 49 with respect to the first reinforcing member 54 and the gap G3 between the front end portion 45a of the roof 45 and the front ear 42b of the front wall 42 of the eaves 41 is , G4 ≦ G3. For this reason, it can insert easily, rotating as the arrow Y1 so that the front wall part 51 may not hit the front-end | tip part 45a of the roof 45. FIG.

  As shown in FIG. 7B, the lower member 49 continues to descend while rotating and the bottom wall 53 is parallel to the bottom wall 44 of the eaves 41, as shown in FIG. The bottom wall 53 abuts against the front wall 42, the rear wall 43, and the bottom wall 44 of the eaves 41, respectively. More specifically, since the rear wall portion 52 is approximately half the height of the rear wall 43, the bottom wall 53 maintains a sufficient space with respect to the bottom wall 44 while the lower member 49 is being rotated. It can be rotated so that it is parallel to 44.

  For this reason, since it is possible to prevent the adhesive applied to the bottom wall 44 of the eaves 41 from being peeled off by the bottom wall 53, the eaves inner joint 47 extends over the ends 41b of the pair of eaves 41. Thus, the front wall portion 51, the rear wall portion 52, and the bottom wall portion 53 can be reliably connected to ensure water-stopping. In addition, the front wall portion 51, the rear wall portion 52, and the bottom wall portion 53 of the lower member 49 are bonded to the front wall 42, the rear wall 43, and the bottom wall 44 of the eaves 41 using an adhesive, Since the engaging portion 51b of the upper end portion 51a is engaged with the front ear 42b, temporary joining can be performed reliably and easily in a state where the end portions 41b of the pair of eaves 41 are abutted during construction.

  As shown in FIGS. 8 (a) and 8 (b), when the upper member 48 is inserted into the eaves 41, the upper member 48 has a concave shape, so that the tip of the roof 45 extends deeply into the concave inner space G5. 45a can be inserted. Therefore, the upper member 48 can be easily inserted while rotating as indicated by the arrow Y2.

  Then, in a state where the upper end portion 57a of the rear portion 57 is abutted and locked to the rear ear 43b, the second reinforcing member 58 contacts the first reinforcing member 54, and the second inclined piece 56b of the upper member 48 is the lower member 49. The first inclined piece 51c is locked.

  Here, since the engaging piece 58b is inclined at an angle θ = 40 degrees from the center line side, the engaging piece 58b can be easily covered with the first reinforcing member 54, and therefore the second reinforcing member 58 is the first reinforcing member 58. It can be automatically positioned and inserted along one reinforcement 54. This eliminates the need for an operator to look into the eaves 41 to confirm the position, thereby improving work efficiency. In addition, the safety of construction work at high places is increased.

  Thus, since the eaves rod inner joint 47 is formed by dividing the upper member 48 and the lower member 49 into upper and lower parts, even when the gap G3 between the upper end portion 42a of the eaves rod 41 and the tip portion 45a of the roof 45 is narrow, By inserting the upper member 48 and then the lower member 49, the eaves inner joint 47 can be easily inserted into the eaves 41.

  The lower member 4 and the upper member 48 have the first reinforcing member 54 and the second reinforcing member 58 to improve the lateral strength of the eaves 41. Therefore, even if the eaves receives an impact from the outside, the joint in the eaves 47 does not come off.

Further, the vicinity of the lower end portion 57 b of the rear portion 57 of the second reinforcing member 58 having the same width S as the first reinforcing member 54 is engaged with both sides of the second reinforcing member 58 so as to protrude in parallel along the lower end portion 57 b of the rear portion 57. The part 58a is provided with an engagement piece 58b that hangs down.

  For this reason, the second reinforcing member 58 reaches the predetermined position of the first reinforcing member 54 surely and easily only by sliding the second reinforcing member 58 across the both sides of the first reinforcing member 54 by the engaging pieces 58b. Can contact. In addition, since the pressing force acts on the entire area of the lower member 4 by the second reinforcing member 58, the eaves-rod inner joint 47 can be securely brought into close contact with the eaves 41 and the engagement can be improved.

  The material of the eaves and the inner joint is made of stainless steel, galvanized metal, synthetic resin material such as hard vinyl chloride resin in consideration of weight reduction and corrosion resistance, or synthetic resin on both sides of the metal plate Formed by coating the material.

  The first protrusion and the second protrusion formed on the upper end portions 42a and 43a of the front wall 42 and the rear wall 43 of the eaves 41 are formed in a structure independent of the front ear 42b and the rear ear 43b. The upper member 48 or the lower member 49 may be latched.

  The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes and the like within the scope of the present invention are included in the present invention. It is.

  For example, when the pair of engaging pieces 58b is slightly wider, for example, when the width S = 42 mm, the engaging pieces 58b can be covered and guided on the first reinforcing member 54 more easily.

  The engagement piece 58b may be formed at an angle θ = 0 degrees without being inclined from the center line side.

  The first reinforcing material 54 and the second reinforcing material 58 may not be diagonal materials that rise from the rear wall portion 52 toward the front wall portion 51. Depending on the cross-sectional shape of the eaves 41, a horizontal material may be used.

  The protrusion 54a of the first reinforcing member 54 and the engaging portion 58a of the second reinforcing member 58 are not limited to the horizontal state, and may be formed on the same inclined surface as the first reinforcing member 54 and the second reinforcing member 58.
