Description of the Related Art In recent years, siding materials that can shorten the construction period by dry-type construction, have a wide variety of products, and are excellent in workability have been widely used as exterior materials for buildings. Are impressed with their excellent design.

低でも10mm程度の幅が必要とされる。[0003] When this siding material is applied, a sealing material is previously provided on the plate material at the connection portions of the siding materials that are adjacent in the vertical direction (up-down direction), so that waterproof treatment is not required. However, with respect to the connection portions of the siding materials adjacent to each other in the left-right direction, after waterproofing the siding material to the base, a waterproofing treatment is performed with a polyurethane-based or modified silicone-based sealing material. This kind of sealing material requires a function of expanding and contracting to some extent in response to the movement of the plate material and the base material. If the width of the sealing material is too narrow, the absolute amount of elongation becomes small, so a width of at least about 10 mm is required. Needed.

低下を招くという問題も生じる。By the way, in the case of an exterior material having a tile or brick-like pseudo joint formed on the surface, the difference between the pseudo joint and the joint between the plate materials is reduced to make the appearance less noticeable. In order to enhance the property, it is necessary to form a pseudo joint on the surface of the plate material to a width corresponding to the joint width between the plate materials, but if the width of the vertical joint between the horizontally adjacent plate materials is large as described above, For the purpose of making the vertical joints inconspicuous by the pseudo joints, the width of the pseudo joints must be increased in accordance with the vertical joints, and fine pseudo joints cannot be formed. As a result, not only is there a limitation in terms of the design of the exterior material, but also a problem arises in that the strength of the exterior material is reduced by the wide pseudo joints.

In this case, by improving the joint structure between the exterior materials adjacent to each other in the horizontal direction, it is possible to secure a stable sealing property and waterproofness at the joints regardless of the movement of the exterior material and the base material, and thus the exterior material An object of the present invention is to make it possible to reduce the width of the pseudo joint formed on the surface to secure an increase in the strength of the exterior material, to eliminate restrictions on the design of the exterior material, and to improve the workability.

なるようにした。In order to achieve the above object, according to the present invention, a joint material having elasticity and waterproofness is bonded in advance to a lateral end surface of a sheathing material, and the jointing condition of the sheathing material is determined. Sealing the joint portion in a state where the joint material is compressed between the lateral end face of the adjacent exterior material, and the width of the joint material in the compressed sealing state is substantially the same as the pseudo joint of the exterior material surface. I did it.

材の目地構造が前提である。More specifically, according to the invention of claim 1, a plurality of exterior members having pseudo joints of a predetermined width provided on the outer wall surface of the building are fixed in a state where they are arranged vertically and horizontally. It is premised on the joint structure of the exterior material in which a material exterior surface is configured and a gap is formed at least between the exterior materials adjacent in the horizontal direction to form vertical joints.

れている構成とする。A joint material having elasticity and waterproofness and having a width larger than that of the pseudo joint is bonded to one lateral end face of the exterior material in advance, and the exterior materials are adjacent to each other in the lateral direction. In the state where the joint material is fixed to the outer wall surface of the building, the joint material adhered to one of the exterior materials adjacent in the lateral direction is in close contact with the lateral end surface of the other exterior material, and is formed by the joint material. The finished width of the vertical joint is set to be substantially the same width as the pseudo joint.

た外観が得られる。According to the above configuration, since the vertical joint between the exterior materials adjacent to each other in the horizontal direction and the pseudo joint provided on the surface of the exterior material have substantially the same width, it is possible to distinguish the two joints from the outside in appearance. It is not possible to obtain an integrated appearance as a whole exterior surface despite the fact that the exterior surface of the building is composed of a plurality of exterior materials.

A plurality of horizontally long exterior materials provided with pseudo joints of a predetermined width on the surface are arranged in a vertical direction, and of these exterior materials, an exterior material adjacent in the vertical direction is located at a lower end of the upper exterior material. The female part and the male part at the upper end of the lower exterior material are fixed to the outer wall surface in a fitted state, while the exterior material adjacent to the lateral direction is the female part of one exterior material. And an outer member fixed to the outer wall surface in a state where the male member of the other outer member is fitted to the outer surface, and a gap is formed between the outer members on the surface side of the fitting portion to form a vertical joint. The joint structure is assumed.
