Description

[Detailed explanation of the idea] 【Technical field】

This invention connects the left and right roof panels with a joint to form a metal roof by covering the roof with metal roofing materials. Regarding connection structure.

[Background technology]

Since iron plates are easily corroded by rust, copper plates,
Aluminum joints have long been used as joints formed from different materials with metal roofing materials such as colored galvanized iron sheets, vinyl chloride-coated steel sheets, stainless steel sheets, and ricin steel sheets. However, in such a conventional example, if the covering of the roof sheet comes off, there is a risk of corrosion due to electrical contact between the metal of the roof sheet and the aluminum of the joint.

[Purpose of the invention] This invention was developed in view of the technical background described above, and its purpose is to prevent rust on joints and corrosion caused by electric contact, and to prevent roofing with metal covers. The purpose is to cover the space between the plates to improve the weather resistance of a synthetic resin joint and to prevent the synthetic resin from appearing on the outside.

[Disclosure of invention]

The connection structure of the roofing material of the present invention is such that a joint part 3 having a substantially T-shaped cross section is protruded from the top surface of the waste board 1 to form a joint 7 made of synthetic resin, and the surface of the waste board 1 and the back surface of the joint part 3 are connected. The side edge of the metal roofing material 4 is inserted into the fitting groove 5 formed between them, and a lower edge portion 6 folded back toward the back side is provided at the lower end of the roof plate 4 in the water flow direction. The lower end of the sacrificial plate 1 is fitted into the groove part 6, and the cover 8 is placed over the top surface of the joint part 3.
The lower end of is bent downward to form a fitting part 9,
This structure is characterized in that the lower flap part 6 of the roof plate 4 is inserted into the fitting part 9, thereby achieving the above object. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. What is shown in FIG. 3 is a joint 7 that is a synthetic resin molded product (injection molded), and is molded from synthetic resin such as vinyl chloride, polypropylene, ABS resin, acrylic resin, and nylon. This is the waste board 1
A joint portion 3 having a substantially T-shaped cross section is integrally protruded from the surface of the joint portion 3, and left and right fitting grooves 5 are formed between the back surface of the joint portion 3 and the surface of the sacrificial plate 1. Ribs 11 are provided at regular pitches on the back surface of the upper plate 10 of the joint part 3 to increase the rigidity of the joint part 3. In addition, a plurality of drain grooves 12 are provided in the vertical (water flow) direction on the surface of the waste board 1 to smooth drainage and prevent horizontal flow, and water stopper projections are formed on both ends of the surface of the waste board 1. A strip 13 is provided protrudingly. Further, an upper water stop 14 is provided at the upper end of the sacrificial board 1 so as to protrude toward the front surface, and a lower water drainer 15 is suspended from the lower end toward the back surface. The roof plate 4 is made by bending metal materials such as a copper plate, a colored galvanized iron plate, a vinyl chloride-coated steel plate, a stainless steel plate, and a ricin steel plate, and has a lower edge portion 6 extending toward the back side at the lower end. An upper flange 16 extends toward the front surface at the upper end. The cover 8 is also made of metal like the roof plate 4, and has a flat cut-out ring shape in cross section with an opening groove 17 cut into the back surface, and the lower end is approximately U-shaped toward the back surface. A bent fitting portion 9 is provided. As shown in FIGS. 1 and 2, the side ends of the roof board 4 are inserted into the left and right fitting grooves 5 of the joint 7, and the lower end of the waste board 1 is inserted into the bottom flap of the roof board 4. 6
In this way, the left and right roof panels 4 are connected via the joint 7 while positioning the joint 7 and the roof panel 4. After this, the cover 8 is inserted into the upper plate 10 of the joint part 3 by sliding it from below, and the lower flap part 6 of the roof board 4 is inserted into the fitting part 9 of the cover 8 to position the cover 8. . In this state, as shown in Fig. 1, the upper part of the sacrificial board 1 protrudes beyond the roof board 4, but this will be reliably hidden by the roof board 4 when the upper roof board 4 is installed. . Moreover, the lower end of the joint part 3 is also covered by the cover 8.
It is covered by the fitting part 9 of. In this way, the synthetic resin joint 7 is not exposed, and there is no problem with weather resistance. 4 to 6 are other examples of the present invention, in which the upper plate 10 of the joint portion 3 is partially provided at regular pitches as shown in FIG.

[Effect of the idea]

Since the present invention is constructed as described above, the joints are prevented from being corroded by rust or electric contact.
Moreover, even though synthetic resin joints are used, the joints are covered by the roof plate and cover and are not exposed, which has the advantage of not damaging the appearance and solving the problem of weather resistance of the joints. In particular, since the fitting part of the cover covers the lower end of the joint part, this part can be protected.
