Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a joint for connecting plate-shaped exterior materials such as roofing materials.

[Background Art] As shown in FIG. 4, the conventional joint A' for connecting exterior materials includes an upper plate 4 having a T-shaped cross section integrally provided on the surface of a lower plate 1, and an end of the exterior material opening laterally. Part fitting groove 7
However, when connecting and constructing the exterior material 8, it is not only difficult to fit the end portion into the exterior material end fitting groove 7, but also has poor workability.
There were problems in that the ends of the exterior material 8 or the upper plate 4 were damaged, and rainwater entered between the exterior material and the lower and upper plates due to capillary action.

[Purpose of the invention] This invention was created in view of the above circumstances, and its purpose is to improve the workability of connecting exterior materials and to reliably prevent the infiltration of rainwater due to capillary action. The purpose of the present invention is to provide a joint for connecting exterior materials.

[Disclosure of the invention] The exterior material connection joint of the present invention has a locking convex portion 2 to a locking recess 3 along the longitudinal direction on the surface of the lower plate 1.
A locking concave portion 3 to a locking convex portion 2 are provided on the back surface of the upper plate 4 along the longitudinal direction, and a locking convex portion 2 to a locking convex portion on the front surface of the lower plate 1 and the back surface of the upper plate 4 are provided. recess 3
Soft drain ridges 5 and top drain ridges 6 are provided protrudingly along the longitudinal direction on both sides of the sewage drain ridge 5 and top drain ridge 6 are respectively provided with upper and lower locking convex portions 2 to the locking recess 3 side, and connecting the lower plate 1 and the upper plate 4 via the locking convex part 2 and the locking recess 3 and opening laterally. A matching groove 7 is formed, and with this configuration, the above object can be achieved. That is, when connecting the exterior material 8, the lower plate 1 and the upper plate 4 can be disassembled, and when the exterior material 8 is connected, the exterior material 8 and A gap is formed between the upper and lower plates 4 and 1 to prevent rainwater from entering due to capillary action.

The present invention will be described below based on embodiments shown in the accompanying drawings. The lower plate 1 is an extrusion molded product, and is formed by inserting a metal plate 9 such as an aluminum plate, a stainless steel plate, a galvanized iron plate, or a copper plate into a resin plate such as polyvinyl chloride, polyethylene, or polypropylene. At approximately the center of the surface of the lower plate 1, a locking convex portion 2 having a T-shaped cross section is provided extending along the entire length thereof in the longitudinal direction. In addition, on the surface of the lower plate 1, a plurality of soft drainage ridges 5 are provided on both sides of the locking convex portion 2 in parallel with the locking convex portion 2. A seal portion 10 is provided protrudingly. Upper plate 4
This is an extrusion molded product, which is formed by inserting a metal plate 9 into a resin plate in the same way as the lower plate 1. A locking recess 3 having a substantially T-shaped cross section is formed at approximately the center of the back surface of the upper plate 4 over the entire length in the direction of the eaves.
Further, on the back surface of the upper plate 4, a plurality of soft draining ridges 6 are provided on both sides of the locking recess 3 in parallel with the locking recess 3. The drain ridge 5 slopes upward toward the center of the lower plate 1, and the top drain ridge 6 slopes downward toward the center of the upper plate 4, allowing for smooth fitting of the exterior material 8. We are trying to make it possible. An exterior with a U-shaped cross section that opens laterally by fitting the locking recess 3 of the upper plate 4 and the locking protrusion 2 of the lower plate 1, and connecting the upper plate 4 and the lower plate 1 in a removable manner. A material end fitting groove 7 is formed to constitute a joint A for connecting the exterior material. Note that the locking recess 3 may be formed on the lower plate 1 side, and the locking protrusion 2 may be formed on the upper plate 4 side. Further, these locking protrusions 2 and locking recesses 3 may be provided partially. Next, the connection of the exterior material 8 using this exterior material connection joint A will be explained. First, the lower plate 1 and the upper plate 4 are disassembled, and the ends of the exterior material 8 are placed on the left and right sides of the locking convex part 2 of the lower plate 1, and in this state, the locking convex part of the lower plate 1 is 2 top plate 4
By fitting the locking recess 3, the exterior material 1
1 is fitted into the fitting groove 7 of the exterior material end of the joint A. In this case, the back surface of the end of the exterior material 8 comes into elastic contact with the drain ridge 5 and the waterproof seal part 10, the end surface of the exterior material 8 comes into elastic contact with the water drain ridge 6, and the surface of the lower plate 1 and the upper plate 4 A gap is formed with the back surface to prevent rainwater from entering due to capillary action.
Note that the exterior material 8 is attached only to one side of the locking convex portion 2 of the lower plate 1.
The upper plate 4 may be connected to the lower plate 1 with the ends thereof arranged, and then the ends of the outer sheathing material 8 may be fitted into the outer sheathing material end fitting grooves 7.

[Effect of the invention] In the present invention, a locking convex portion or a locking recess is provided along the longitudinal direction on the surface of the lower plate, and a locking recess or a locking recess is provided along the longitudinal direction on the back surface of the upper plate. A locking convex portion is provided, and a groove for fitting the exterior material end that opens laterally is formed by connecting the lower plate and the upper plate through the locking convex portion and the locking concave portion, so that the exterior When connecting the materials, the lower plate and the upper plate are disassembled, and after placing the end of the exterior material on the side of the lower plate, connect the lower plate and the upper plate through the locking convex part and the locking recess. By connecting the upper plates,
The end of the exterior material can be connected by fitting it into the groove for fitting the end of the exterior material, making it easy to connect the exterior material, and there is no damage to the end of the exterior material or the top plate unlike in conventional methods. In addition, drain draining ridges and top draining ridges are provided protruding along the longitudinal direction on both sides of the locking protrusion or locking recess on the front surface of the lower plate and the back surface of the upper plate, respectively. When the exterior material is connected, gaps are formed between the exterior material and the upper and lower plates by the drainage ridges, which prevents rainwater from entering through the fitting groove at the end of the exterior material due to capillary action. be. In addition, since the drainage ridges and the top drainage ridges are inclined upwardly and downwardly towards the locking protrusion or the locking recess, the sewage draining ridges and the top drainage ridges prevent the exterior material from being damaged. The exterior material fitted into the end fitting groove becomes difficult to come out due to the resistance of the drainage ridges and top drainage ridges, and conversely, after connecting the lower plate and the upper plate, the exterior material is inserted into the exterior material end fitting groove. Even when it is fitted into a water tank, the sloping ridges of the sewage drain and top drain ridges allow for smooth fitting.
