DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structural improvement of a connecting portion of a fixed-length roof shingle in a flow direction.

[0002]

2. Description of the Related Art Conventionally, when a roof is constructed using a vertically-roofed roof, it is mainly performed using a long roof shingle. It would have been good to use a roof shingle molded at the factory, but if the length is long, the molding machine installed at the factory and the coil that will be the material will be brought to the site and processed on the spot, so the timing of bringing in The adjustment of the roofing material was troublesome, and the handling of the formed roof material was inconvenient and very troublesome.

On the other hand, as a method of forming a long thatched roof which is long in the flow direction, for example, as shown in Japanese Patent Publication No. 4-43135, a plurality of fixed-size roof slabs are connected in the flow direction. What has been proposed. As shown in FIG. 1, this is a case in which folded roof portions b and b are provided at the ridge side end and the eave side end of the fixed-sized roof slabs b and b, respectively, which are disposed on the base board a in the flow direction. A part d is formed so that they are engaged with each other.

However, according to such a connection structure, the eaves side and the ridge side ends of the shingle b are complicated in shape, so that the molding cost is increased and the overlapped portion c or the overlapped portion d is added. In the event that deformation occurs before construction, it is difficult to correct it on site, and since there is no escape place for rainwater that has entered the gap between the overlapped part c and the overlapped part d, it overflows and floods inside. There was a risk of doing.

Further, since the overlapped portion c and the portion to be overlapped d are generally press-molded, the range of the thickness which can be formed by the same mold is extremely limited to, for example, about 0.2 mm. In addition, there is a problem that a plurality of molds are required to perform the process, and the cost is high.

The present invention has been made in view of such a conventional problem, and has a good workability of a connecting portion in a flow direction, is easy to handle, and has a good rain-repellent performance. Its main purpose is to provide a board connection structure.

An eaves side of a vertically-roofed roof slat laid on the ridge side of the joint member, comprising a discarded plate member facing inward and a water stopping member provided in the discarded plate member and having at least one groove formed therein. Folded portions are formed at the end and at the ridge side end of the vertically-roofed shingle which is also laid on the eaves side, and these folded portions are inserted into the grooves of the water-stopping member, and the vertically-roofed adjoining flow direction The shingles were connected to each other.

According to a second aspect of the present invention, the discarded member according to the first aspect of the present invention has a volume space that is at least twice as large as the water blocking member.

[0009]

According to the first aspect of the present invention, since the shape of the connecting portion of the vertical roofing shingle is a simple shape in which the end on the eaves side or the ridge side is simply folded down, molding is easy. Further, even if deformation occurs on the site, it can be easily dealt with, and particularly, even a thick plate that is difficult to work on is easily repaired, so that the on-site repairability is extremely good. In addition, it is possible to easily cope with a joint of a roof having a complicated shape on site. Furthermore, only one or a very small number of molds are required, which is economical.

On the other hand, since the side end of the discard member faces the drainage member, the rainwater that has entered the discard member is drained smoothly, and the connection structure has an excellent drainage capacity and therefore has a good performance in raining. Is obtained.

According to the second aspect of the present invention, since the discard plate member has a sufficient volume space, even if rainwater enters from the water stopping member, the rainwater does not flood into the indoor side, and furthermore, the better rain closing performance Is exhibited.
