Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a joint material used, for example, in an outer wall of a building to seal a narrow groove-like joint groove formed between adjacent outer wall materials forming the outer wall of the building. More specifically, the present invention relates to a joint material configured to seal a joint groove only with a seal lip.

[0002]

[Prior art]

 The basic structure of this kind of joint material is that the whole is integrated, and seal lips are provided on both sides of the main body. Then, when the main body is press-fitted into the joint groove, each seal lip is elastically deformed and elastically contacts the inner wall surface of the joint groove, thereby sealing the joint material while maintaining the sealing property. As described above, the conventional joint material has a structure that seals and seals the joint groove only by the elastic deformation of the seal lips protruding on both side surfaces of the main body portion, so that the sealing performance is made too high. I couldn't.

[0003]

[Problems to be solved by the device]

 The present invention has been made for the purpose of improving the sealing property of a joint material which is configured to seal the joint groove only by the seal lip.

[0004]

[Means for Solving the Problems]

 The present invention for solving the above-mentioned problems is a joint material comprising a fixed joint material which is inserted and fixed to the bottom side of a joint groove, and a press-fit joint material which is press-fitted into the main body of the fixed joint material. The fixed joint material has seal lips protruding from both side surfaces of the main body, and press-fitting grooves having a width gradually narrowing downward are formed on the top surface of the main body to form the press-fitting groove. The inner wall surfaces of the groove facing each other are formed with engaging portions having a serrated cross section, and the press-fitting joint material has a cover plate at the upper end of the press-fitting main body whose width gradually narrows downward. Part is integrally provided, and engaging portions having serrated cross-sections are formed on both side surfaces of the press-fitting main body part, and the main part of the fixed joint material is inserted and fixed at the bottom side of the joint groove. The press-fitting main body portion of the press-fitting joint material is press-fitted into the groove, and each inner wall surface of the press-fitting groove and the press-fitting main body portion. It is characterized by being configured the respective engaging portions formed respectively on each side to engage with each other.

[0005]

[Function of the device]

 When the fixed joint material is inserted into the bottom side of the joint groove, the seal lip elastically deforms to elastically contact the inner wall surface of the joint groove, and the main body portion also elastically deforms to narrow the width of the press-fit groove. In this state, when the press-fitting main body of the press-fitting joint material is press-fitted into the press-fitting groove of the fixed joint material, the main body of the fixed jointing material is pushed to both sides in the press-fitting groove portion, and this pushing force expands the seal lip. Is strongly elastically contacted with the inner wall surface of the joint groove, and the joint groove is sealed.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to examples. FIG. 1 is a perspective view showing a state in which a fixed joint material A and a press-fit joint material B, which form a joint material according to the present invention, are separated, and FIG. 2 is a perspective view of the press-fit joint material B seen from below. FIG. 3 is a cross-sectional view showing a state in which the fixed joint material A and the press-fit joint material B are separated. 1 to 3, a joint material according to the present invention is press-fitted into a fixed joint material A which is inserted and fixed to a bottom side of a joint groove 13 (see FIG. 3) and a main body portion 1 of the fixed joint material A. And a press-fitting joint material B. The fixed joint material A has a plurality of seal lips 2 protruding from both side surfaces of the main body 1, and a press-fitting groove 3 having an opening on the upper surface is formed in the central portion of the main body 1. The width of the press-fitting groove 3 is gradually narrowed downward, and engaging portions 4 having a serrated cross section are formed on the inner wall surfaces facing each other. Further, the press-fitting joint material B has a shape in which the cover plate portion 6 is integrally provided on the upper end portion of the press-fitting main body portion 5. The press-fitting main body portion 5 of the press-fitting joint material B corresponds to the shape of the press-fitting groove 3 of the fixed joint material A, and has a width gradually narrowing from the upper side to the lower side. 2 is formed, the engaging portion 7 is provided with longitudinal slits 8 at predetermined intervals along the longitudinal direction, as shown in FIG.

As shown in FIG. 3, an outer wall material 11 that constitutes an outer wall of a building is fixed to a backup material 12, and a joint groove 13 having a predetermined width is formed between adjacent outer wall materials 11. . Then, as shown in FIG. 4, when the fixed joint material A is inserted into the joint groove 13, the seal lip 2 is elastically deformed to elastically contact the inner wall surface 13a of the joint groove 13 and its main body portion. 1 is also elastically deformed, and the width of the press-fitting groove 3 is narrowed. Next, as shown in FIGS. 5 and 6, when the press-fitting main body portion 5 of the press-fitting joint material B is press-fitted into the press-fitting groove 3 of the fixed jointing material A whose width is narrowed by elastic deformation, the portion of the press-fitting groove 3 is pressed. At this time, the main body portion 1 is pushed to both sides and the width of the press-fitting groove 3 which has been narrowed is widened, and the press-fitting main body portion 5 of the press-fitting joint material B is press-fitted into the press-fitting groove 3. Since the main body 1 of the fixed joint material A is expanded to both sides in the press-fitting groove portion 3, the elastic contact force of the seal lip 2 elastically contacting the inner wall surface 13a of the joint groove 13 is further increased, and the sealing property is improved. To be enhanced. When the press-fitting main body portion 5 of the press-fitting joint material B is press-fitted into the press-fitting groove 3 of the fixed joint material A, the engaging portion 4 formed on the inner wall surface of the press-fitting groove 3 and the side surface of the press-fitting main body portion 5 are formed. The engaged fitting portions 7 are engaged with each other, and the press-fit joint material B does not come out from the fixed joint material A.

When the press-fitting main body portion 5 of the press-fitting joint material B is press-fitted into the press-fitting groove 3 of the fixed jointing material A, the press-fitting joint material B is not inclined parallel to the fixed jointing material A but is slightly inclined and press-fitted. Thus, even when the ridge lines of the engaging portions 4 and 7 provided in the respective portions intersect, the engaging portions 7 formed on both side surfaces of the press-fitting main body portion 5 have a longitudinal direction. Since the longitudinal slits 8 are provided at predetermined intervals along, the press-fitting main body portion 5 of the press-fitting joint material B into the press-fitting groove 3 of the fixed jointing material A can be press-fitted without any trouble.
