Description

  The present invention relates to a connection structure for uneven roof materials, and more particularly to a connection structure in which a plurality of uneven roof materials are connected in a roof gradient direction.

  Generally, metal vertical roofing materials such as uneven roofing material, folded plate roofing material, and vertical flat roofing material are constructed as a single piece of roofing material that is seamless in the direction of the roof slope, so it is said to have excellent water-stopping properties. There are advantages. However, such vertical metal roofing materials are often used in large buildings such as factories and gymnasiums, and are therefore long in the longitudinal direction and cannot be transported in a molded state. For this reason, for example, a metal vertical roofing material used for a large building carries a roll forming machine and a roll-shaped metal plate (a so-called hoop material) on-site, and is formed on the site by a roll forming machine. Installed and installed.

  By the way, such a vertical roofing material may be used for a residential house. Construction of a vertical roofing material in a house is often not possible to secure a site area enough to carry in a roll forming machine, and the roofing material is transported to the site by a truck or the like. Note that in conventional residential houses, gable roofs and dormitory roofs are the mainstream, so the length in the eaves ridge direction is short, and therefore a roof material having a size that can be transported by a truck or the like can be used.

  However, in recent years, with the widespread use of solar panels, the number of residential houses having a large roof area such as a single-flow roof has increased, and the number of large-sized residential houses has also increased. For this reason, the case where the length of the eaves direction of the roof of a house is longer than the roof material which can be conveyed is increasing.

  Here, Patent Document 1 discloses a structure in which a vertical casing is connected in the flow direction while ensuring a high water-stopping property. The exterior material described in Patent Document 1 is a so-called vertical flat roof material in which inner rising portions are provided on both left and right sides of a central face plate portion.

  The water-side end of this exterior material is connected to the water-side end of another exterior material by overlapping from above. As a result, the roof structure described in Patent Document 1 is configured by connecting a plurality of vertically-wrapped exterior materials along the flow direction.

JP-A-9-125621

  By the way, this exterior material has a structure in which the inner rising portions at both ends in the width direction of the face plate portion are easily bent in the left-right direction. For this reason, in the exterior material of this patent document 1, when connecting a some exterior material to a flow direction, exterior materials can be piled up and down.

  However, for example, a concave and convex roofing material in which concave and convex portions are repeatedly formed in the eave direction is such that the convex portions are continuous at both ends in the left and right direction of the concave portion, and the concave portions are continuous. The structure is difficult to do. For this reason, in this uneven roof material, even if it tried to connect in the flow direction, the ends could not be overlapped, and the conventional method could not be connected in the flow direction.

  The present invention has been made in view of the above circumstances, and the purpose of the present invention is to flow between the uneven roof materials in which the concave portions and the convex portions are repeatedly formed in the eave direction while ensuring water-stopping properties. An object of the present invention is to provide an uneven roof material connection structure that can be connected in directions.

  The connection structure of the uneven roof material of the present invention is a connection structure of an uneven roof material in which a concave portion and a convex portion are repeatedly formed in the eave direction, and the first uneven roof material and the first uneven roof material A second uneven roof material disposed on the water side and abutted against the water-side end surface of the first uneven roof material, and a seam between the first uneven roof material and the second uneven roof material is covered. A connection plate, and the connection plate, the first uneven roof material, and a sealing material covering between the connection plate and the second uneven roof material are provided.

  According to the connection structure of the uneven roof material of the present invention, the uneven roof materials in which the concave portion and the convex portion are repeatedly formed in the eave direction can be connected in the flow direction in a state in which water-stopping property is ensured.
