Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure for metal roofing roofing boards for improving the workability of roofs of buildings.

[0002]

2. Description of the Related Art Conventionally, a metal roof plate is made of a synthetic resin in order to further improve weather resistance and corrosion resistance on a zinc iron plate (galvanized iron plate) whose surface is galvanized. Colored iron plates on which a coating film such as paint is formed are used. In addition, when the roof of a building is to be roofed with the above-mentioned metal roof plate, a method of constructing a seamless long product and a construction of a standard product that has been previously folded at the connecting part are constructed. There is a way to do it.

First, in the method of constructing a long product, the winding material such as the above-mentioned zinc iron plate or color iron plate wound in a longitudinal strip shape and a folding machine are carried into a construction site, and the metal roof plates The folding machine, which folds the connection part, bites from the band-shaped tip of the above-mentioned winding material, adds a predetermined folding process, and produces a long metal roof plate corresponding to the construction site on the roof. Process and form. In addition, the length of the roof plate obtained in this way is 18 meters if it is long even in a general house, and to carry it to the roof where the construction of this length is to be carried, collect several sheets. I had to have several people on the rope hanging up at the same time. Further, in such a roofing construction using a long object, it is often difficult for a single worker to handle, especially when there is wind, and due to the recent housing site situation that the residential area is complicated, In many cases, it is impossible to process and form a long object up to 18 meters at the construction site.

On the other hand, in order to solve the inconvenience of the above-mentioned long products, a connecting portion is preliminarily folded for connection, and a plurality of standard products each having a length of about 4 meters are generally joined together. The roofing construction for the roof was devised, but this is the thatching construction with a standard length. And, in thatching construction by the standard length object, as compared with thatching construction by the long length object, since a seam occurs at the connecting portion of the mutual metal roof plates,
It has the drawback of poor rain performance, and various connection structures have already been devised as solutions to these drawbacks. When the above-mentioned connection structure is roughly classified, there are one in which the roof plate and the waste plate are integrally formed, and one in which the waste plate and the roof plate are separately formed. Here, FIG. 5, FIG. 6, and FIG. 7 show a structure that is widely used as a connecting structure for a metal horizontal thatched roof plate with a standard length in the inland region of the Tohoku region, which is a snowy region. . As shown in the figure, the metal roof plate used in the conventional connection structure is one in which a roof plate and a waste plate are integrally formed. The eaves-side connecting portion formed on the eaves-side lower edge and the ridge-side connecting portion formed on the ridge-side upper edge of the lower roof plate are hooked to connect. At this time, the eaves-side connecting portion is formed of a folded-down portion that is folded inward from below the plate portion of the roof plate and a folded-back portion that is folded back outward from the tip of this folded-down portion.
On the other hand, the ridge-side connection portion is folded up from the upper side of the plate portion to the inside, and is folded back horizontally from the tip of this folded portion to the above plate portion to prevent the progress of rainwater and the like in the middle. For this reason, the contact plate has a bulged portion that is bulged in an arc shape, and a return portion that is folded back upward from the tip of the contact plate. Next, each of the left and right adjacent roofing boards also has the hooking piece formed on the right edge of the roofing board of the left roofing board hooked to the waste board connection receiving part formed on the left end of the roofing board of the right roofing board. Then, fit the convex part formed by the upper folded part outside of the left roof plate into the concave part formed by the folded part inside of the discarding plate connection receiving part of the right roof plate,
Connection is made by abutting the contact plate of the left roof plate on the plate of the right roof plate. At this time, the waste board connection receiving part is formed by a return piece folded back from the left side of the plate part of the roof plate to the inside and a bulge in an arc shape inside the return part at the left end to prevent the progress of rainwater and the like. It has a bulging part that is formed, and is formed from a return plate part that is folded back outward from the tip of the return piece and extends to form a waste plate, and a return part that is folded back upward from the tip of the waste plate part. . On the other hand, the hooking piece is formed by being folded inward from the right side of the roof plate portion. Incidentally, in the upper portion of the hanging piece formed by being folded down, a corresponding portion which is further folded by forming the ridge-side connecting portion next is cut in advance, but the lower portion of the hanging piece is It is folded together as an eaves side connection part. Then, in the lower part of the scrap board connection receiving part, the corresponding part that is folded further by forming the eaves side connecting part is cut beforehand, but the upper part of the waste plate connecting receiving part is the ridge side connection. Folded together as a part. Subsequently, again, the connection between the discard board connection receiving portion formed on the left side of the plate portion of the right roof plate and the hooking piece formed on the right edge of the plate portion of the left roof plate is performed by connecting the right roof plate. The hooking piece of the left roof plate is hooked on the folding projection formed by the return piece and the waste board in the waste board connection receiving part.
