Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for sealing a joint portion of a rain gutter, and more particularly to a method for sealing a joint portion which enables easy and efficient sealing from the inside of the rain gutter.

[0002]

2. Description of the Related Art For sealing a joint portion of a conventional rain gutter of this type, for example, as shown in FIG. 4, a joint plate having a U-shaped cross section is formed on the inner surfaces of the end portions of adjacent gutter bodies a and b. c
After mounting, the joint plate c is fixed to the gutter main bodies a and b, and a masking tape (not shown) is attached around the sealing portion between the joint plate c and the gutter main bodies a and b. The sealing agent d is applied from the sealing gun g to the gap between the joint plate c and the gutter main bodies a and b and the entire contact portion, and the sealing agent d is pushed into the gap with the finishing spatula e to finish, and then the masking tape It was common to peel it off and seal the joint of the rain gutter.

[0003]

However, the above-mentioned conventional sealing method requires a space for moving and using the sealing gun and the finishing spatula for sealing, and thus it is difficult to work in a place where the space is small. There was a problem. In addition, the conventional sealing method has a problem that the work is complicated because it is necessary to attach a masking tape around the sealing portion or peel off the masking tape after finishing with a spatula. Furthermore, in the conventional sealing method, since it is necessary to surely fill the sealant with a finishing spatula to every corner, it requires skill and consumes more sealant than necessary to improve the reliability of the seal. There was a problem. Moreover, when the conventional method is carried out, there is a problem that the applied sealant must be protected so as not to cause dust and surface scratches until it is cured.

The method for sealing the joint according to the present invention is as follows.
This is a completely new technology developed in view of the above-mentioned problems of the related art, and in particular, it is possible to fill the joint between the gutter body and the joint plate with a sealing agent by an extremely simple operation, and an unskilled person can seal it. However, the present invention provides a technique that can be surely carried out, and can surely perform the sealing with the minimum consumption of the sealing agent.

[0005]

A method for sealing a joint portion according to the present invention is a technique which has fundamentally improved the above-mentioned conventional problems, and the gist thereof is to define the end portions of adjacent gutter bodies. In the method of joining with a joint plate placed on the inner surface of the end of the gutter body, a pair of backup materials that maintain a predetermined space between the joint plate and the gutter body are almost the same as the edge of the gutter body. Through holes are provided in parallel at predetermined positions of the joint plate corresponding to each other between the pair of backup members, and further surrounded by the gutter body, the joint plate and the pair of backup members from the through holes. The joint is sealed by filling the sealing passage with a sealing agent.

[0006]

As described above, in the method for sealing the joint portion according to the present invention, a pair of backup members are provided at a predetermined interval between the gutter body and the joint plate placed on the gutter body. It is possible to form a closed sealing passage by a gutter body, a joint plate, and a pair of backup materials. Further, in the method according to the present invention, since the through hole and the sealing passage are communicated with each other by forming the through hole in the joint plate, the sealing agent is surely filled in the sealing passage through the through hole. You can do it.

Therefore, the through hole can be filled with the sealing agent from the joint plate side without using the sealing gun to move the sealing gun. Regarding the filling in the sealing passage, the completion of sealing can be confirmed at the openings at both ends of the sealing passage. In addition, there is no waste of the sealing agent filled in the sealing passage, and the sealing can be completed with the minimum necessary sealing agent.
