Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rigid joint structure for a roofing material made of metal, which is attached by connecting in a rigid direction and closing the connecting portion to cover the entire roof of a building.

[0002]

2. Description of the Related Art As shown in FIGS. 9 and 10, a conventional roof joint structure has a drainage goby 23 having both ends and an upper end folded inward, and a lower goat 2 having a lower end folded downward.
Standing goby 2 to insert the roofing material 25 in the middle of 4
1 is provided to form the drain gutter 22 and the roof material 25 is inserted and connected to both sides of the waste gutter 22. The joint material 20 covers the standing goby 21 from the top to cover the roof material 25. A method of fixing the is known.
In addition to such a method, as shown in FIGS. 11 and 12, a drainage goby 33 having both ends and an upper end folded inward,
Further, a drainage convex portion 31 is provided in the middle of the lower goby 38 whose lower end is folded outward, and when a roof material 35 is placed on both sides of the convex portion, a supporting material 34 for supporting the roof material 35 is provided. The gutter 32 is formed, and the goby part 3 is provided on the upper half side surface of the same gutter 32.
The roofing material 35 having the hard end portion 7 mounted thereon is placed, the roofing material 35 having the goby portion 37 provided at the other hard end portion is mounted on the other upper half side surface, and the mounted roofing material 35 A method of covering and fixing both of the goby portions 37 with the joint cover 30 has been known.

[0003]

However, the conventional method has the following drawbacks. The drain gutter and the joint cover are indispensable as a waterproof member.The roof gutter is attached to the drain gutter and the joint part covered with the joint cover has a large thickness. There are some restrictions, and it takes a considerable amount of time to roof the roof with a skylight and a chimney by the conventional method. Further, although the roof material is fixed by the drain gutter and the joint cover, there is a defect that the fixing portion is weak and the roof material is easily deformed, and it is not preferable because the joint cover floats up from the viewpoint of appearance. The present invention solves the above-mentioned drawbacks, improves watertightness, has a drainage mechanism, does not require a joint cover, and does not restrict the roofing order due to left-right symmetry, and provides skylights and chimneys. Even the roof surface can be hollowed out and easily installed. Another object of the present invention is to provide a rigid joint structure for a metal stepped roof, in which the strength of the insertion portion for inserting the roof material into the winding goby and attaching it is high, and the deformation of the roof material is small.

[0004]

Means for Solving the Problems The gist of the present invention, which has solved the above problems, is as follows: 1) A drain gutter with a drainage goby having both ends folded inward, and a bottom goby having its lower end folded downward are disposed vertically upwards in the center of the gutter. A winding goby having two ends on both sides wound inward is attached to form a roof material mounting gutter, and one of the winding gobs attached to the roof material mounting gutter is a goby provided at a hard end portion of the roof material. A roofing material characterized in that the roofing material is inserted in a state in which the part is wrapped up, and is inserted in a state in which the goby portion provided at the hard end of another roofing material is wrapped in the other winding goby, and the roofing material is connected. 2) The rigid joint structure of the roof material according to 1), wherein the gaps in the joint are closed with an elastic material.

[0005]

In this structure, when rainwater flows down on the upper surface of the roofing material while the whole roof is roofed according to the present invention, the rainwater flows in from the joint portion, but the gap between the joint portions serves as a water channel, and Most of the rainwater flows down in the direction. However, due to the force of rainwater flowing down the gap and the capillary phenomenon,
Rainwater that has flowed into the winding goby attached to the roof material mounting gutter becomes a channel in the goby space inside the winding goby, and the rainwater flows down into the goby space. Further, when rainwater also leaches out from the winding goby due to the force of the rainwater, the rainwater flows down on the upper surface of the drain gutter having the drainage goby having both ends folded inward. The rainwater that flows down does not leach up to the roof surface by the drainage goby provided in the drain gutter.

By using the roof material mounting trough, the joint cover is not required, and the water tightness and the drainage function by the winding goby are excellent. Further, by closing the elastic material in the gap of the joint portion, intrusion of rainwater from the gap is eliminated and dust and the like are prevented from entering the gap. Since the joints are symmetrical, hollow roofing can be done without any restrictions on the roofing order, and the goby portion provided at the hard end of the roofing material can be easily inserted into the roof material mounting gutter. It can be attached to the winding goby with the goby portion of the roofing material being wrapped. The strength of the insertion part is high and the deformation of the metal stepped roof is small.
