Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a technique for water storage at joints between exterior materials and exterior materials.

[Background Art] Conventionally, as shown in FIG. 2, the exterior material 4 is applied to the front surface of the wall base material 1, and the exterior material 4 is nailed to form the exterior material 4.
Was attached to the wall base material 1. Then, the caulking material 12 is filled between the exterior material 4 and the adjacent exterior material 4 to perform waterproofing treatment on the joint groove 8 portion. However, conventionally, the work of filling the caulking material 12 on site was troublesome. In the conventional case, the caulking material 12 is 1
Since it was only heavily waterproofed, the waterproofness in the joint groove 8 part was not sufficient. Furthermore, the filling work of the caulking material 12 on site varies depending on the ability of the operator and the situation of the site, and in this respect also, it cannot be said that the waterproof property is sufficient. In addition, since the caulking material 12 is not filled on site, it may be possible to elastically fit the gasket into the joint groove 8, but this gasket is held in the joint groove 8 only by the elastic fitting force of the gasket. However, there is a problem in that the holding force of the gasket is weak and the gasket easily comes off the joint groove.

Therefore, as another conventional example, for example, in Japanese Utility Model Laid-Open No. 59-179929 and Japanese Utility Model Laid-Open No. 55-71244, a horizontal joint sealing for elastically contacting fins with the side end surface of the exterior material is applied to a joint drainer. Although a structure for stopping the sealing is disclosed, the waterproof structure is only a fin between the sealing material for lateral joints and the exterior material, and not only the waterproof property cannot be sufficiently enhanced, but the sealing material for lateral joints is not There is also a drawback that it is embedded in the gutter and the appearance of the joint gutter is impaired.

[Object of the Invention] The present invention was devised in view of the problems of the above-described conventional example, and its purpose is to ensure waterproofness in joint groove portions formed between adjacent exterior materials. Adjacent exterior materials can be brought close to each other so that the gasket can be firmly adhered, and joint drainer can be formed thin so that the exterior material can be made close to the wall base material. As a result, the entire outer wall can be stored thinly, and the on-site work can be simplified without the need for the on-site troublesome work of filling the caulking material, and moreover, the gasket is fitted into the joint groove. However, it is another object of the present invention to provide a water blocking structure for the joint portion of the exterior material, which can surely prevent the gasket from coming off the joint groove.

[Effects of the Invention] According to the present invention, as described above, the engaging portion formed in the central portion on the front surface side of the joint drainer is formed in the shape of a single protruding piece, and the gasket has joints. Since there is a groove-shaped locked part that can be fitted outside the convex-shaped locking part of the draining metal fitting, the end faces of adjacent exterior materials are brought close to each other, and the gasket is jointed. Since it can be surely brought into close contact with the drainage fitting, and the portion of the joint drainage fitting other than the locking portion can be formed thin, it can be installed so that the adjacent exterior materials are close to the wall base material. The outer wall as a whole can be stored thinly, and the elastic front plate part makes elastic contact with the front surface of the exterior material, elastic fins make elastic contact with the side end surface parts of the exterior material, and drainage with a drainage ridge makes three different distinctions. Prevent water from entering by means of water ingress prevention It is possible to prevent it and to ensure water scavenging.Furthermore, since a gasket is fitted in the joint groove, it is possible to avoid the troublesome work of filling caulking material on site like in the past. A locking part was provided in the center part on the surface side of the joint drainer, and a locked part was provided at the rear end of the central vertical piece, and the locked part of the gasket was locked to the locking part of the joint drainer. Therefore, even though the gasket is fitted in the joint groove, the gasket can be locked to the joint drainer to prevent the gasket from coming off from the joint groove. Is formed of a material having elasticity, such that the locked portion of the gasket is locked to the locking portion of the joint draining metal fitting, and the locking portion formed in the central portion on the surface side of the joint draining metal fitting is a single unit. In the shape of one convex piece Since the gasket is provided with a locked portion formed in a groove shape that can be fitted to the outside of the convex-shaped locking portion of the joint drainer, the locked portion is a locking portion. Before the insertion and engagement, the groove-shaped engaged portion can be contracted and deformed so that the vertical piece of the gasket can be easily inserted into the joint groove, and the engaging portion can be inserted and engaged in the engaged portion. After this, the gasket is securely fixed in the joint groove without shrinking and deforming the groove-shaped locked part.In this way, the vertical piece of the gasket can be easily inserted into the joint groove, and It can be attached so that it will not come out easily from the gutter.
