Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a corner body 1 is extruded from a ceramic material and has an L-shaped cross section and a hollow shape, and an inner surface 3 that can come into contact with a right-angled corner of a prism 2 is formed. A hollow sleeve portion 4 having a thickness thinner than that of the corner body 1 is extended laterally almost flush with the inner surface 3, and a rib 16 is formed in the hollow sleeve portion 4 to cross the hollow portion. , a stepped portion 7 is formed at the boundary between the sleeve portion 4 and the corner main body 1 into which the side end portion of the exterior plate 5 can be inserted, and a vertical drainage groove 8 is formed at the location where the rib 16 is formed on the front surface of the sleeve portion 4. An exterior plate 5 is formed on the side end of the corner body 1 and is in contact with the exterior plate 5.
This relates to an exterior corner member characterized in that a vertical groove 13 is formed into which a protruding vertical piece 14 formed on the side end surface of the housing can be inserted.

Conventional corner members were made of metal plates, which made it difficult to produce straight lines, and in addition, the vertically long exterior corner members had a spacer function on the lateral side to be attached to the horizontal edge of the exterior plate. There was a problem with installing the edges, which required a lot of work. Furthermore, since the vertical rim and the exterior corner members were formed separately, there was a problem in controlling rain between the two, and rainwater also entered through the contact area between the exterior plate and the vertical rim due to capillary action. There was a problem.

The present invention was made in view of this problem, and its purpose is to make it possible to easily create straight lines by extruding the corner body, and to also form vertically long sleeves on the vertically long corner body. By integrally molding the parts, it is possible to omit the construction of a vertical rim that has a spacer function, and in addition, it is possible to ensure rain protection between the corner body and the sleeve part as the vertical rim, and furthermore, the front part of the sleeve part By providing a vertical drainage groove in the sleeve, it is possible to suppress the infiltration of rainwater due to capillary phenomenon at the point where the exterior plate and the sleeve contact, and also to reduce the weight while maintaining the vertical drainage groove without weakening the strength of the sleeve. An object of the present invention is to provide an exterior corner member capable of forming a drainage groove.

Embodiments of the present invention will be described in detail below based on the drawings.

Reference numeral 1 designates a vertically elongated corner body, which is obtained by extruding a compound of a suitable ceramic material through a die having a predetermined cross-sectional shape, maintaining the shape, and then heating and curing it. The corner body 1 can be cut to an appropriate length with a wood saw. The corner body 1 has an inner surface 3 that can come into contact with the outer surface of the right-angled corner of the prism 2, and an outer surface 9 that is substantially parallel to the inner surface 3. Further, at both ends of the L-shaped corner body 1, sleeve portions 4 are integrally formed substantially flush with the inner surface 3 of the corner body 1, extending toward adjacent studs (not shown). The thickness a of the sleeve portion 4 is approximately equal to the thickness b of the horizontal waistband 10. Thus, a stepped portion 7 is formed in front of the sleeve portion 4 into which the side end portion 6 of the exterior plate 5 enters. A lateral furrow abutment surface 12 is formed at the side end of the sleeve portion 4 to which the side end surface 11 of the lateral furrow 10 can come into contact. This lateral furring abutting surface 12 is formed approximately at right angles to the inner surface 3 of the corner body 1. Further, a vertical groove 13 is formed at the side end of the corner body 1 facing the front step 7 of the sleeve portion 4 and opening in the direction of the stud. Further, two vertical drainage grooves 8 are provided on the front surface of the sleeve portion 4. As shown in the drawings, the corner main body 1 is nailed to the prism 2, and the side end surface 11 of the lateral rim 10 is nailed to the lateral rim 10 of the sleeve portion 4 of the corner main body 1 to the prismatic pillar 2 and the stud. On the other hand, a protruding vertical piece 14 is provided at the side end of the exterior plate 5.
is provided. This protruding vertical piece 14 is fitted between the vertical grooves 13 of the corner body 1 via a caulking material 15, and the exterior plate 5 is fitted and connected to the corner body 1. Then, the exterior plate 5 is attached to the horizontal rim 10 by nailing or the like. In such a case, the side end 6 of the exterior plate 5 enters the front step 7 of the sleeve 4, and the inner surface of the exterior plate 5 is in contact with the outer surface of the sleeve 4. However, the sleeve portion 4 of the lever can be made into a vertical body rim, and the construction of the vertical body rim is omitted. The protruding vertical piece 14 of the exterior plate 5 is connected to the vertical groove 13 of the corner body 1.
It is embedded in the rain to ensure that it will stop raining. Further, the vertical drainage grooves 8 provided in the sleeve portion 4 prevent capillary phenomenon at the portion where the sleeve portion 4 and the exterior plate 5 are in contact with each other, thereby suppressing the infiltration of rainwater. The corner body 1 and the sleeve portion 4 are hollowed out, and their ribs 16 increase their strength. The vertical drainage grooves 8 are recessed in the portions of the sleeve portion 4 where the ribs 16 are formed, so as not to weaken the strength of the sleeve portion 4.

As described above, in the present invention, since the corner body is extruded, a straight line can be easily formed as an exterior corner member, and since the vertically long sleeve portion is integrally molded with the vertically long corner body, the spacer can be easily formed. It is possible to omit the construction of a functional vertical hemline, and since the corner body and sleeve are integrally molded, there is no problem with rain drainage between the two, and there is also a vertical drainage groove on the front of the sleeve. Since this is provided, it is possible to suppress rainwater from entering through capillary action at the location where the exterior plate and the sleeve portion contact each other. In addition, a vertical groove is formed on the front surface of the sleeve part, and the side end of the corner body is a groove, and the vertical recess into which the protruding vertical piece formed on the side end surface of the exterior plate can be inserted into the contact surface with the exterior plate. Since the groove is formed, when the exterior plate is brought into contact with the front surface of the sleeve part and the protruding vertical piece of the exterior plate is inserted into the vertical groove and connected, the exterior plate is brought into contact with the front surface of the sleeve member. In addition, by fitting the protruding vertical piece into the vertical groove, it is possible to connect in a stable contact state, and in addition to the draining effect of the vertical water cut groove, by fitting the protruding vertical piece into the vertical groove, a synergistic draining effect can be achieved. In other words, there is an advantage that the water cutting effect can be greatly enhanced by the action of cutting off the capillary phenomenon by the vertical water cutting groove and by increasing the water transmission path by fitting the protruding vertical piece into the vertical groove. Moreover, the corner body is made of ceramic material and extruded into a hollow shape.
As an exterior corner member, it can be made of ceramic material to provide a sense of weight, while being hollow, eliminating the drawback of heavy ceramic products and reducing weight. There is an advantage in that the vertical drainage grooves formed on the front surface of the housing plate and the vertical grooves into which the protruding vertical pieces of the exterior plate can be fitted can be formed easily and with high accuracy. Furthermore, by making the corner body hollow and the sleeve portion also hollow, the weight of the corner member is significantly reduced, but the inner and outer dimensions are smaller than that of the corner body. When making a sleeve part hollow and forming a vertical drainage groove on the front surface, we solved the problem of the hollow sleeve part having small internal and external dimensions becoming weak in strength by applying the above-mentioned ribs to the front surface of the sleeve part. This problem can be solved by forming a vertical drainage groove.
This solves the problem of strength in the sleeves while reducing weight.
