Description

The present invention relates to a connection structure of a metal vertical roofing material and a metal vertical roofing material .

In general, for a metal vertical thatched roof, it is ideal from the viewpoint of water stoppage to use one vertical roofing material that is continuous in the eaves ridge direction without providing a seam in the middle part of the roof surface in the eaves ridge direction. Is. However, there is a limit to the size that can be transported by truck or the like (about 12 m). For this reason, if the length of the roof surface in the eaves direction exceeds the size that can be transported by truck or the like, the molding machine and the metal coil material are brought into the construction site, and the roof material is molded at the construction site. ..

However, in order to bring the molding machine to the construction site, a space where the molding machine can be installed is required at the construction site. Moreover, when a long roofing material is used, there is a problem that it cannot be handled in a narrow space during construction and the displacement due to thermal expansion and contraction becomes large after installation.

On the other hand, a construction method is known in which a plurality of roofing materials divided in the direction of the eaves are connected at the time of construction to form a roof surface (see, for example, Patent Document 1). In the construction method described in Patent Document 1, the roofing materials are connected to each other by overlapping the roofing materials on the ridge side with the roofing materials on the eaves side. In each roofing material, a plurality of ridges are provided in the portion where the roofing materials overlap each other, and the rainwater entering between the roofing materials is blocked by the ridges to maintain high water stopping property.

The builder fixes the eaves-side vertical roofing material 2a to the eaves of the cliff, fixes the ridge-side bottom surface 21a to the field board 1 as shown in FIG. 3A, and stands on the right side as shown in FIG. The upper portion 22 is fixed to the field plate 1 with a hanger 61 described later. Next, as shown in FIG. 3B, the builder inserts the engaging portion 51 of the ridge-side vertical roofing material 2b between the folded-back portion 411 of the eaves-side vertical roofing material 2a and the bottom surface portion 21, and also inserts the engaging portion 51 of the ridge-side vertical roofing material 2b and the side folded-back portion 411a. The side engaging portion 51a is inserted between the rising portion 22 and the rising portion 22. In this state, similarly to the eaves-side vertical roofing material 2a, the ridge-side bottom surface 21a of the ridge-side vertical roofing material 2b is fixed to the field plate 1, and the rising portion 22 on the right side is fixed to the field plate 1 with a hanger 61. The builder repeats this process in the direction of the eaves.

Next, the builder installs another vertical roofing material 2 so as to be adjacent to the right side of the fixed vertical roofing material 2. Specifically, the rising portion 22 on the left side of the other vertical roofing material 2 is inserted from below the locking side 613 on the right side of the hanger 61, which will be described later, and the bottom surface portion 21a on the ridge side and the standing portion on the right side are similarly described above. The upper portion 22 is fixed to the field plate 1. As shown in FIG. 4, adjacent vertical roofing materials 2 are connected by a connecting member 6. The connecting member 6 of the present embodiment is composed of a cap member 62 and a hanger 61.

The hanger 61 is erected with a fixing piece 611 fixed to the field plate 1 via a fixing tool 7, and an upright portion 612 extending upward from the end of the fixing piece 611 on the side of the existing vertical roofing material 2c. A pair of locking pieces 613 formed at the upper end of the portion 612 are provided. The hanger 61 is made of a rigid material such as iron, aluminum, or plastic. The locking piece 613 extends from the upper end portion of the erection portion 612, and is inclined so as to be located downward as the distance from the erection portion 612 increases.

The plurality of suspenders 61 are arranged at a predetermined pitch along the direction of the eaves building. The pitch of the plurality of suspenders 61 is, for example, 300 to 455 mm. After fixing a plurality of hangers 61 to the field board 1, the builder installs another vertical roofing material 2 (referred to as 2d in FIG. 4) so as to be adjacent to the hangers 61. The vertical roofing material 2d is the same as the method for attaching the vertical roofing material 2c, which was performed earlier.

After the vertical roofing material 2 is laid over the entire roof surface, the builder causes the locking piece 613 of the hanger 61 to hold the cap member 62.

The cap member 62 extends in the direction of the eaves and is formed over the entire length of the roof surface in the direction of the eaves. The cap member 62 includes a holding portion 63 having a triangular cross section that can be held by the locking piece 613, and a roof surface holding portion 64 that extends downward from the holding portion 63.

The builder fits the cap member 62 into a pair of adjacent rising portions 22. Then, the holding portion 63 is held by the locking piece 613, and the lower end portion of the roof surface pressing portion 64 comes into contact with the upper surface of the bottom surface portion 21 of the vertical roofing material 2. As a result, the cap member 62 can cover between the vertically adjacent vertical roofing materials 2 in the left-right direction, and the water stopping property can be improved. Further, since the cap member 62 can be attached after the vertical roofing material 2 is installed, the vertical roofing material 2 can be connected in the left-right direction separately from the vertical roofing material 2 in the eaves direction. As a result, the difficulty of work can be reduced.
