Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a structure for horizontally connecting exterior materials having a plurality of horizontally oriented pattern grooves on their surfaces.

[Background Art] As shown in FIG. 7, an exterior material 1 made of a ceramic material such as asbestos cement is often provided with horizontally oriented pattern grooves 2 in order to provide a pattern on the surface. Conventionally, the jointer 3' that connects this exterior material 1 is formed of metal in the shape of a vertically long plate, as shown in FIG. ' was installed protrudingly. Then, the joiner 3' is brought into contact with the rear side of the adjacent exterior materials 1 arranged at a joint interval so as to span both exterior materials 1, and the convex portion 4' and the adjacent exterior materials 1 are brought into contact with each other.
A joint groove 5' consisting of a convex portion 4' and a convex portion 4' was filled with a caulking material 6'. In such a conventional example, as shown in FIG. 4, in the part without the pattern groove 2, the distance between the convex portion 4' and the surface of the exterior material 1 is dimension a, and the thickness of the caulking material 6' is thick. In the part where the pattern groove 1 is located, as shown in FIG. 5, the distance between the convex portion 4' and the surface of the pattern groove 2 becomes dimension b (a>>b), and the thickness of the caulking material 6' becomes thinner. , poor adhesion occurs in this area, causing the caulking to break, making it easier for rainwater to infiltrate. In other words, since the convex portion 4' of the jointer 3' is provided over the entire length, the thickness of the caulking material 6' in the pattern groove 2 portion is reduced.

[Effects of the invention] This invention was made in view of the points mentioned above, and the purpose of this invention is to increase the thickness of the caulking material even in areas with patterned grooves to eliminate cuts in the caulking material. An object of the present invention is to provide an exterior material connection structure that can improve waterproofness.

[Disclosure of the invention] The exterior material connection structure of the present invention consists of exterior materials 1 having a plurality of vertically oriented patterned grooves 2 on their surfaces arranged horizontally with a joint interval in between, A vertically long plate-shaped joiner plate 3 is brought into contact with both exterior materials 1, and convex portions 4 for maintaining joint spacing are provided at intervals in the vertical direction of the jointer plate 3. Match the pattern groove 2 with the missing part, and connect the space between the adjacent exterior materials 1 and the joiner plate 3.
This joint groove 5 is filled with a caulking material 6, and the drawbacks of the conventional example are solved by constructing it as described above. That is, the convex portions 4 that maintain the joint spacing are provided at intervals in the vertical direction of the joiner plate 3, and the convex portions 4
By making the pattern groove 2 correspond to the part without the pattern, the depth of the joint groove 5 becomes deeper even in the part where the pattern groove 2 is present, making it possible to fill the caulking material 6 thickly, thereby extending the entire length of the joint. It is now definitely waterproof.

The present invention will be explained in detail below using examples.

As shown in FIG. 7, the exterior material 1 is made of a ceramic material such as asbestos cement, and has a plurality of horizontal pattern grooves 2 vertically spaced at appropriate intervals on its surface. As shown in Fig. 3, the joiner board 3 is made of a material such as synthetic resin and is formed into a long board shape, and has draining edges 7 on both sides, and a joint interval in the longitudinal direction in the center of the width direction. A plurality of protrusions 4 for holding are provided at appropriate intervals in the longitudinal direction. Therefore, when connecting the exterior materials 1, a plurality of exterior materials 1 are arranged in the left-right direction, and a joiner plate 3 is placed on the back side between adjacent exterior materials 1 so as to span both exterior materials 1.
are brought into contact with each other, and the protrusions 4 are positioned between the end faces of adjacent exterior materials 1 to maintain the joint spacing with the protrusions 4, and the pattern grooves 2 of the exterior material 1 are made to correspond to the portions without the protrusions 4. A joint groove 5 formed by the end face of the material 1 and the joiner plate 3 is filled with caulking material 6. When connected in this way, the thickness of the caulking material 6 in the part without the pattern groove 2 will be the dimension a as shown in FIG. 1, and the thickness of the caulking material 6 in the part with the pattern groove 2 as shown in FIG. has a dimension c (a≈c), and the thickness of the caulking material 6 becomes thick over the entire length of the top and bottom, and the caulking material 6 is firmly bonded with a large bonding area.

[Effects of the invention] As described above, the present invention provides projections that maintain the joint spacing in the vertical direction of the joiner board at intervals, and also makes the parts without the projections correspond to the pattern grooves.
Since we filled the joint grooves between adjacent exterior materials and jointer plates with caulking material, the depth of the joint grooves becomes deeper even in areas with patterned grooves, allowing for thick filling of caulking material, which makes it easier to connect The caulking material can be reliably bonded over the entire length of the connecting portion with a large bonding area, and the entire length of the connecting portion can be reliably waterproofed.

Claims (1)

[Scope of utility model registration request] Exterior materials that have multiple horizontal pattern grooves on the top and bottom are lined up on the left and right with a gap between the joints, and a jointer board that is long in the vertical direction is placed on the back side of the adjacent exterior materials so as to span both exterior materials. The jointer plate is constructed by abutting the joiner plates, protruding at intervals to maintain the joint spacing in the vertical direction of the joiner board, and matching the pattern grooves to the areas without the protrusions, between adjacent exterior materials and the joiner board. The exterior material connection structure is created by filling the grooves with caulking material.
