Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint treatment method for placing a sealing material on joints such as wall surfaces of buildings.

[0002]

2. Description of the Related Art Conventionally, in order to drive a sealing material on a joint such as a wall surface of a building, a spacer is attached to a predetermined size after cleaning a driving portion. After that, a primer is applied and dried sufficiently, and then a sealing material is cast and the cast surface is finished by using a spatula or the like.

[0003]

In such a conventional joint treatment method, the work of embedding the spacer and the work of placing the sealing material are carried out separately, and both of them are carried out manually, which requires a lot of time. Was spending effort. Furthermore, since it depends on the experience and intuition of craftsmen to secure the joint depth, it is difficult to construct joints having a uniform and sufficient depth.

An object of the present invention is to provide a joint treatment method capable of solving the disadvantages of the above-mentioned conventional example, saving labor and shortening the working time, and capable of uniform joint molding even by an unskilled worker. To do.

[0005]

According to the present invention, in order to achieve the above-mentioned object, a spacer (large) 5 and a spacer (small) 6 are arranged in the same longitudinal direction with a sealing material 7 in between, and the outside is The joint treatment material 2 is formed by wrapping the release film 8 with cuts 9 in the length direction of the release film 8, and a spacer (large) 5 or a spacer (small) 6 of the joint treatment material 2 is formed.
From the side to the sealing material 7 is embedded in the joint 1, and then
The purpose is to remove the remaining spacer (small) 6 or spacer (large) 5 coming out from the joint 1 and the release film 8 opened at the cut 9.

[0006]

According to the present invention, the work of embedding the spacer and the work of placing the sealing material can be performed at the same time, the labor of the work can be saved and the time can be shortened, and the sealing material having a uniform and sufficient depth can be easily formed. Can be installed. Further, the spacer has versatility because the size of the joint can be selected to be large or small.

[0007]

Embodiments of the present invention will now be described in detail with reference to the drawings. 1 to 3 show one embodiment of the joint treatment method of the present invention, in which 1 is a joint and 2 is a joint treatment material used in the present invention. The joint 1 is formed between the end portions of the mounting flat plate 4 provided on the support base portion 3.

On the other hand, the joint treatment material 2 is a spacer (large) 5
And the spacer (small) 6 are lined up with the sealing material 7 in the same direction in the same length direction, and the outside is wrapped with the release film 8 to form an integral rod-shaped body. Spacer (large) in the example shown
5, the sealing material 7, and the spacer (small) 6 are all trapezoidal, and the upper side and the lower side of the trapezoids are matched with each other on the surfaces to be joined to each other so that the whole is a trapezoid having a vertically long shape.

The release film 8 has a spacer (large).
A cut 9 is provided in the lengthwise direction on the outer side of the spacer 5 and the spacer (small) 6. It is preferable that the cut 9 has a built-in cut tape or the like and can be cut by pulling the cut tape. A one-component moisture-curing type sealing material is used as the sealing material 7.

Next, the joint treatment method of the present invention using such a joint treatment material 2 will be described. After the cleaning of the joint 1, the protection of the periphery of the joint, the application of the primer, and the curing are completed, the joint treatment material 2 is pushed into the joint 1. At this time, which side of the spacer (large) 5 and the spacer (small) 6 is pushed in is selected according to the size of the joint 1.

In the case of FIG. 2, when the spacer (large) 5 is used, the space from the spacer (large) 5 side to the sealing material 7 is embedded in the joint 1 together with the release film 8. In this way, the remaining spacer (small) portion 6 comes out of the joint 1 together with the release film 8.

Therefore, the release film 8 is opened at the cuts 9, and the open release film 8 and the remaining spacers (small) 6 that protruded are removed as shown in FIG. After that, a spatula is used to sufficiently bring the sealing material 7 and the mounting plate 4 into close contact, and the surface of the sealing material 7 is finished.

In the case of FIG. 3, the spacer (small) 6 is used, and the remaining spacer (large) 5 and the release film 8 are similarly removed.

Further, as a method for removing the release film 8,
As shown in FIG. 4, the spacer (large) 5 and the spacer (small) 6 are removed at the same time, as shown in FIG. 5, the release film 8 is pulled out to the support base portion 3 side, and as shown in FIG. Various methods can be selected, such as first peeling off the release film 8 and then separating the spacer (large) 5 or the spacer (small) 6. It depends on which cut 9 is opened as required.

Further, the joint treatment material 2 is packaged in a case 10 as a product to be sold, as shown in FIG.
It is convenient to transport and store the whole.

[0016]

As described above, according to the joint treatment method of the present invention, the work of embedding the spacer and the work of placing the sealing material can be performed at the same time, so that the work can be saved and the time can be shortened. Further, even a non-skilled worker can easily apply the sealing material so as to have a uniform and sufficient depth, which is useful for improving accuracy. Further, the spacer has versatility because the size can be selected depending on the size of the joint.
