Description

[Detailed description of the invention] 【Technical field】

The present invention relates to a technique for finishing a joint formed between exterior materials.

[Background technology]

Conventionally, two methods have been used: filling the joints between exterior materials with caulking material, and press-fitting joint covers made of rubber or synthetic resin into the joints between exterior materials. However, the former method has problems in that the finished product has a poor appearance, and the finished product may not be as good as it should be, especially depending on the level of skill of the installer. Also, in the latter method,
When the width of the joint becomes wider due to thermal expansion and contraction of the exterior material, the adhesion of the joint cover becomes weaker, causing a problem in that rainwater and the like tend to penetrate.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned technical background 1, and its purpose is to improve the finish of the joints between exterior materials and to ensure high water resistance.

[Disclosure of the invention]

The method for constructing the joints of the exterior material of the present invention is that after filling the joints 2 of the exterior material 1 with caulking material 3, and before the caulking material 3 hardens, an anchor piece 5 is provided protruding from the back surface of the joint cover 4.
is press-fitted into a caulking material 3, the joint 2 is covered with a joint cover 4, and the joint cover 4 is held by the caulking material 3. Therefore, the double structure of the joint cover 4 and the caulking material 3 can prevent rainwater from entering the inside of the outer wall from the joint 2.
Moreover, high watertight performance can be obtained by the caulking material 3 filled in the joints 2, and the joint cover 4 protects the caulking material 3 from ultraviolet rays and the like to prevent deterioration over time. In addition, since the joint cover 4 is held in place by the caulking material 3, there is no need to worry about the joint cover 4 falling off even in the event of an earthquake, and the joint cover 4 allows the joint 2 to be beautifully finished regardless of the skill of the installer. This is something that can be obtained. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The exterior material 1 is a plate-shaped material made of inorganic material such as cement, and is installed on the surface of a base material 6 such as an outer wall. A sacrificial plate 7 made of metal or the like is arranged on the back side of the joint 2 when the exterior material 1 is open, so that the base material 6 is not directly exposed from the joint 2. A protrusion 8 is provided in the center of the sacrificial board 7 over its entire length. playing a role. Further, water return pieces 9 are provided at both ends of the waste board 7 to prevent moisture from entering. By arranging the exterior material 1 on both sides of the waste board 7 fixed on the base material 6 in this way, a joint 2 is formed corresponding to the protrusion 8. A viscous fluid caulking material 3 is filled over the entire length of the tube. On the back side of the joint cover 4 made of synthetic mm'ti for covering the joint 2, there is an anchor piece 5 having a pull-out stopper 10 first.
is provided protrudingly, and after filling the caulking material 3, the anchor piece 5 is press-fitted into the caulking material 3 before the caulking material 3 hardens, and the anchor piece 5 is embedded in the caulking material 3. The joint cover 4 is held and fixed, the caulking material 3 and the joint 2 are covered up by the decorative part 11 of the joint cover 4, and the joint 2 is beautifully finished. In addition, in the fiSi diagram, both side edges of the hard decorative part 11 of the joint cover 4 are overlapped on the surface of the exterior material 1. In the one shown in FIG. 2, a soft decorative portion 11 of a joint cover 4 is press-fitted into the joint 2.

【Effect of the invention】

As described above, after filling the joints between exterior materials with caulking material, anchor pieces protruding from the back of the joint cover are press-fitted into the caulking material before the caulking material hardens. Since the joint cover is covered with a cover and the joint cover is held by caulking material, the double structure of the joint cover and caulking material prevents rainwater etc. from entering the inside of the exterior wall from the joint. The material provides high watertight performance, and the joint cover protects the caulking material from ultraviolet rays and prevents it from deteriorating over time. In addition, since the joint cover is held in place by the caulking material, there is no need to worry about the joint cover falling off even in the event of an earthquake, and the joint cover allows for a beautiful joint finish regardless of the skill of the installer. It is something.
