BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an eave gutter joint used to connect longitudinal ends of an eave gutter.

[0002]

2. Description of the Related Art Conventional eave gutter joints include the one shown in FIG. 3, the one shown in FIG. 4, and the one shown in FIG. The eaves gutter joint A shown in FIG. 3 is formed with insertion gaps a provided on both sides. The eaves gutter 1 is slid so that the end of the eaves gutter 1 is inserted into the insertion gap a and connected. FIG.
The eaves gutter joint A shown in FIG. 1 is formed of an outer fitting member b whose inner periphery can be elastically fitted to the outer periphery of the eaves gutter 1.
The eaves gutter joint 1 is fitted from outside with a patch-on method in a state where the ends of the eaves gutters correspond to each other. The eaves gutter joint A shown in FIG. 5 has an outer fitting member b whose inner periphery can be elastically fitted to the outer periphery of the eaves gutter 1 and an inner fitting whose outer periphery can be elastically fitted to the inner periphery of the eaves gutter 1. The outer fitting member b and the inner fitting member c of the eave gutter joint A are fitted from inside and outside in a patch-on manner with the ends of the pair of eave gutters 1 corresponding to each other. It has become.

[0003]

However, in the conventional example shown in FIG. 3, when the eaves gutter 1 is connected, the eaves gutter 1 must be slid to insert the end of the eaves gutter 1 into the insertion gap a. In addition, there is a problem that workability when connecting the eaves gutter 1 is poor. In the case of the conventional example shown in FIGS. 4 and 5, the work can be performed by the patchon method and the workability is good, but the adhesion is poor and there is a risk of water leakage.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to improve the workability and improve the adhesion, thereby eliminating the risk of water leakage. To provide gutter joints.

[0005]

In order to achieve the above object, the eaves gutter joint of the present invention comprises an outer joint 2 along the outer periphery of the eaves gutter 1 and an inner joint 3 along the inner periphery of the eaves gutter 1. An inner joint 3 is arranged on the inner periphery of the joint 2 , a fitting projection 4 having a circular cross section in the circumferential direction is formed on the inner surface of the outer joint 2 , and a U-shaped cross section is formed on the outer surface of the inner joint 3 in the circumferential direction.
And a fitting projection 4 and a fitting recess 5 are provided.
DOO detachably fitted to, and adapted to sandwich the end portion of the eaves gutter 1 between the inner circumference and the outer circumference of the inner joint 3 of the outer joint 2, the outer opening surface of the fitting recess 5 of the inner joint 3 5a is the outer surface and inner surface of the inner joint 3.
Opening all together and fitting recess between upper end of inner joint 3
The reinforcing bar 7 is erected so as to be continuous with 5 .

[0006]

According to the above construction, the outer joint 2 and the inner joint 3 are put on the eaves gutter 1 with the ends of the pair of eaves gutters 1 corresponding to each other, and the fitting projections 4 and the fitting recesses 5 are fitted. Together, the outer joint 2 and the inner joint 3 are integrated, and the pair of eaves gutters 1 can be connected by sandwiching the end of the eaves gutter 1 with the outer joint 2 and the inner joint 3.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An eaves gutter joint A is made of synthetic resin and comprises an outer joint 2 and an inner joint 3 as shown in FIG. The outer joint 2 has an inner periphery formed in a shape along the outer surface of the eaves gutter 1, and an ear fitting portion 6 is provided at an upper end of the outer joint 2. On the inner periphery of the outer joint 2, a fitting projection 4 having a circular cross section is provided so as to extend in the circumferential direction at the center in the longitudinal direction. The outer periphery of the inner joint 3 is formed along the inner surface of the eaves gutter 1, and a reinforcing bar 7 is provided between the upper ends of the inner joint 3. A fitting recess 5 having a U-shaped cross section is formed in the outer periphery of the inner joint 3 so as to extend in the circumferential direction at the center in the longitudinal direction. As shown in FIG.
The outer opening surface 5a of the fitting recess 5 is flush with the outer surface of the inner joint 3.
It is open to. The reinforcing bar 7 is located between the upper ends of the inner joints 3.
And is continuous with the fitting recess 5.

In connecting the eaves gutter 1 with the eaves gutter joint A configured as described above, the ends of the pair of eaves gutters 1 are made to correspond to each other, and the outer joint 2 is put over the eaves gutter 1 and the inner joint 3 is attached. The ear fitting portion 6 of the outer joint 2 is fitted to the ear portion 8 of the eaves gutter 1 so as to cover the inside of the eaves gutter 1, and as shown in FIG. The outer joint 2 and the inner joint 3 are integrated by fitting the fitting 4 and the fitting recess 5, and the eave gutter 1 is sandwiched between the inner periphery of the outer joint 2 and the outer periphery of the inner joint 3.

[0009]

[Effects of the Invention] Since the present invention is configured as described above, the outer joint and the inner joint are put on the eaves gutter with the ends of the pair of eaves gutters corresponding to each other, and the fitting projection and the fitting recess are provided. And the outer joint and the inner joint are integrated to form a pair of eaves gutters by sandwiching the end of the eaves gutter between the inner periphery of the outer joint and the outer periphery of the inner joint. The eaves gutter can be attached to the eaves gutter between the joints and the inner joint, so the workability of eaves gutter connection is good. are those able to eliminate the risk of leaks, also the fitting projection on the inner surface of the outer joint, the fitting recess provided on the outer surface of the inner joint, and the outer opening surface of the fitting recess
To make it open flush with the outer surface of the inner joint ,
Not irregularities formed on the outer surface of the outer joint are those capable of improving the appearance and the fitting recess between the upper end of the inner joint
Due to bridged the reinforcing bars as continuous, it is possible to reinforce the joint part state, and are not able to prevent the deformation when an external force is applied to the joint portion, moreover reinforcement rung
Since it is installed so as to be continuous with the fitting recess,
Therefore, the strength of the reinforcing bar is further increased, and as a result, the joint
Intensity minute Ru can be further improved. Further, the fitting protrusion provided in the outer joint in the circumferential direction has a circular cross section, and the fitting recess provided in the inner joint in the circumferential direction has a U-shaped cross section , so that the fitting protrusion and the fitting recess are fitted. when one in which both the can fit smoothly can be brought into close contact with the outer joint and the inner joint reliably eaves gutters.
