Description

  The present invention relates to an eaves joint that connects ends of eaves.

  Conventionally, eaves are provided at the eaves of a building such as a house, and at that time, as illustrated in FIG. 4, adjacent eaves 1 are often connected by an eaves joint 2 (for example, Patent Document 1). , 2).

The eaves joint 2 includes an outer joint 21 along the outer circumferential surface 11 of the eaves 1 and an inner joint 22 along the inner circumferential surface 12 of the eaves 1 so as to sandwich the ends of the eaves 1 from above and below. Connect.

  However, in the above-mentioned conventional eaves joint 2, as illustrated in FIG. 5, when the adhesive 3 for bonding the outer joint 21, the inner joint 22 and the eaves 1 end portion is applied without applying a specified amount, Water leakage may occur.

  Further, the application variation can be reduced by the clamping force at the time of clamping connection, but there is no sufficient effect.

  Of course, as the conventional eaves joint 2, as illustrated in FIG. 6, there is a type in which the end portion of the eaves 1 is connected by only one of the outer joint 21 and the inner joint 22 (FIG. 6 shows the outer joint 21. In this case as well, water leakage may occur due to variations in the application of the adhesive 3.

  Therefore, in view of the circumstances as described above, the present invention may cause water leakage at the connection portion even if the adhesive used in the connection between the eaves end portions by the eaves joint is not uniformly applied. The challenge is to provide an eaves joint with no eaves.

To solve the problems above SL, eaves gutter joint of the present invention is a eaves gutter joint for connecting the ends of the eaves gutters, has an outer fitting and the inner joint, the outer joint and the inner joint eaves groove is provided on the surface of the gutter side, with which a packing having a hollow tunnel shape is provided in the groove, the left and right ends of the outer joint and the inner joint eaves gutter-side surface to the outside position of the packing adhesive is applied, the eaves gutter ends between the outer fitting and the inner joint is held at eaves gutters connection, the tunnel portion of the packing which projects from the groove, is pressed into contact with the eaves gutter end portion groove pushed to the inner, becomes a state where gaps are sealed with eaves gutters end, in this state, by the adhesive, the outer joint and eaves gutter end portion is adhered, is adhered with the inner joint and eaves gutter end is eaves It is characterized in that the end portions can be connected to each other . Furthermore, the eaves joint connection structure of the present invention is an eaves joint connection structure using an eaves joint that connects the ends of the eaves, and the eaves joint includes an outer joint and an inner joint, and the outer joint and the inner joint. A groove is provided on the surface of the joint eaves side, and a packing having a hollow tunnel shape is provided in the groove, and the packing of the packing is provided on the left and right ends of the surface of the eaves side of the outer joint and the inner joint. Adhesive is applied to the outer position, the eaves end portion is sandwiched between the outer joint and the inner joint, and the tunnel portion of the packing protruding from the groove comes into contact with the eave end and is pressed into the groove. In this state, the outer joint and the eaves edge part are bonded together, and the inner joint and the eaves edge part are bonded together in this state. It is characterized by being connected to each other.

According to the present invention, when the eaves are connected, the tunnel portion of the packing protruding from the groove comes into contact with and is pressed into the eaves end, and seals the gap with the eaves end. Even if application variation occurs in the adhesive, water leakage does not occur.

  FIG. 1 shows an embodiment of the present invention.

  In this embodiment, the eaves joint 2 moves the ends of the eaves 1 up and down with the outer joint 21 along the outer peripheral surface 11 of the eaves 1 and the inner joint 22 along the inner peripheral surface 12 of the eaves 1. It is of the type that is sandwiched from and connected.

  In the case of this sandwich connection type, first, an upper surface portion 210 facing the outer peripheral surface 11 of the eaves rod 1 in the outer joint 21, and a lower surface portion 220 facing the inner peripheral surface 12 of the eaves rod 1 in the inner joint 22, respectively. Two rows of grooves 211 and 221 are provided, and packings 212 and 222 are provided in these grooves 211 and 221.

  The packings 212 and 222 have elasticity, and the outer joint 21 and the inner joint 22 are vertically moved with respect to one end of the eave bar 1 with the adhesive 3 applied to the left and right end positions of the upper surface 210 and the lower surface 220 thereof. When crimping from the direction, the portions protruding upward or downward from the grooves 211 and 221 contact and are pressed against the outer peripheral surface 11 and the inner peripheral surface 12 at the end of the eaves rod 1 and into the grooves 211 and 221. It will be in the state where it was pushed in and it can block | close the clearance gap between the eaves 1 end part reliably.

  Due to the presence of the packings 212 and 222, even if the application amount of the adhesive 3 varies (the application amount on the right side is smaller than that on the left side in FIG. 1), the conventional water leakage does not occur.

  For example, as illustrated in FIG. 2, the packings 212 and 222 may have a hollow tunnel shape. Even in this case, the tunnel portions protruding from the grooves 211 and 221 may be When the eaves 1 are connected, they are brought into contact with and pressed into the end of the eaves eaves 1 and are pushed into the grooves 211 and 221, and the gap between the eave eaves 1 end is sealed to effectively stop water. Function can be realized.

  On the other hand, the water stop function using such packings 212 and 222 is also realized by the embodiment illustrated in FIG. 3, for example.

  In the embodiment of FIG. 3, plate-like shapes projecting toward the outer peripheral surface 11 and the inner peripheral surface 12 of the eaves cage 1 on the upper surface portion 210 of the outer joint 21 and the lower surface portion 220 of the inner joint 22, respectively. Protrusions 213 and 223 are provided, and thin-film packings 212 and 222 are provided so as to lean on these protrusions 213 and 223.

  The packings 212 and 222 have an elastic force, and when the outer joint 21 and the inner joint 22 are crimped to the end of the eave ridge 1 as described above, the outer peripheral surface 11 and the inner peripheral surface 12 of the eave ridge 1 end. Is brought into close contact with the side surfaces of the protrusions 213 and 223.

  Thereby, the clearance gap between the edge parts of the eaves 1 is sealed, and even if there is application variation of the adhesive 3, it is possible to effectively prevent water leakage.

  In addition, although the above description is about the pinching connection type eaves joint 2 using both the outer joint 21 and the inner joint 22, it is about the type which consists only of either the outer joint 21 or the inner joint 22. Needless to say, the configuration of the outer joint 21 or the inner joint 22 may be applied as it is.
