DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure between a hanger and a metal roofing material, and more particularly, to a sealing material which enhances workability when connecting a roofing material with a hanger and easily deteriorates with time. The present invention relates to a technology that protects and replaces a joint cover, and that enhances the mounting strength of a joint cover that is mounted across connection points.

[0002]

2. Description of the Related Art Conventionally, a connection structure between a suspender and a metal roofing material is disclosed in Japanese Utility Model Publication No. 6-43320 shown in FIG.
At the upper end of the standing piece 4 of the substantially L-shaped suspension element 5a, fixed lid pieces 4b, 4b are previously formed by folding back and left, and the left and right roofing materials 1, 1 are formed by the left and right fixed lid bodies 4b, 4b. It holds the connection pieces 2 and 2. Then, a joint cover 8a having a seal material 6a attached to the inner surface is put over such a connection portion, and the fixed lid pieces 4b and 4 are placed on the inner surface of the seal material 6a.
b is locked to seal the connection point.

[0003]

However, in such a construction, the suspension 5a is formed by press molding, and the fixed lid pieces 4b, 4b cannot be deformed, and are nailed to the roof foundation. The fixing pieces 2b of the left and right roofing materials 1 are fixed by the fixing lid pieces 4b
And the work of locking and holding the roof material 1 is troublesome, and the workability of the roof material 1 is reduced.

Further, in the conventional configuration, a sealing material 6a is integrated with a metal coating 8a, and the coating 6a is directly exposed to the sun and cooled by cold air at night, causing a large temperature change. Sealing material 6 in direct contact with
a is accelerated, and the sealing material 6a made of rubber or synthetic resin is easily cracked due to the difference in the coefficient of thermal expansion between the coating 8a and the sealing material 6a integrated by an adhesive or the like. Also in this regard, the deterioration of the coating 8a is hastened.

When the sealing material 6a is deteriorated, the sealing property is impaired, and in addition, the metal covering 8a comes into sliding contact with the suspenders 5a and the roof materials 1, 1 and peeling of the coating film progresses.
The generation of rust is also promoted, and the sliding of the metal plates causes problems such as the generation of noise. In addition, in the conventional configuration, the cover 8a attached across the connection portion is configured to be coupled to the suspender 5a via the sealing member 6a integrated on the back surface, so that the mounting strength of the cover 8a is reduced. It is difficult to increase and the sealing material 6a
Is strongly sandwiched between the cover 8a and the fixed lid piece 4b of the suspender 5a, so that the seal member 6a is easily damaged, and the seal member 6a alone cannot be replaced.

The present invention is intended to solve such a problem, and an object of the present invention is to improve workability in connecting a roofing material with a hanger, protect a sealing material, and prevent deterioration. It is an object of the present invention to provide a connection structure between a suspension member and a metal roof material that can replace the seal material when the deterioration occurs due to aging.

[0020]

According to the first aspect of the present invention, there is provided a connecting structure for a metal roofing material in which adjacent roofing materials are connected to each other through a connecting piece standing upright at an end of the roofing material, and a watertight seal is provided at the connection point. The upright piece extends upward from the fixing piece, and the upper end of the upright piece can be bent along the upper end of the connection piece of the roofing material to hold the connection piece. Since the pieces are formed, when laying the roofing material, the bendable pieces of the uprights of the suspenders extend upward without bending, so that the roofing material can be constructed so that it does not become an obstacle. As described above, the fixed lid piece of the suspender does not interfere, and the roof material can be easily installed on the roof.

According to the second aspect of the present invention, since a pair of notches for bending the bendable piece are formed on both sides of the upright piece, the bendable piece can be easily formed between the pair of notches facing each other. In this way, the bendable piece can be easily bent, the thickness of the fixing piece and the standing piece can be increased, the strength of fixing the suspension to the roof base and the strength of the roof material can be improved. There is an advantage that the connection strength can be made sufficient.

According to the third aspect of the present invention, the upright pieces are opposed to the fixed pieces and the upright pieces are combined, so that the opposed upright pieces are provided with bendable pieces, respectively.
The roof material can be connected at the opposing position by these opposing bendable pieces, and the connection strength of the roof material can be increased while being connected by the bendable pieces.

According to the fourth aspect of the present invention, the upright piece extends upward from the fixed piece, and a suspension member having a bendable piece formed at the upper end of the upright piece, and the connecting portion of the roof material is covered by the suspension element. A seal material having a substantially inverted U-shaped cross section, a short clip that holds down the seal material, and a joint cover that covers a connection portion of the roof material over the clip and the seal material,
A metal roofing material is arranged on both sides of the hanging member, and connecting pieces formed upright at the ends of the roofing material are opposed to each other with the rising piece of the hanging element interposed therebetween, and a bendable piece is provided at the upper end of the connecting piece. The roofing material is bent along and the roofing material is connected with the hanging material, and the sealing material is attached across the connection point of the roofing material including the hanging material, and sealed with clips at intervals in the length direction of the sealing material Since the joint cover that holds down the material, forms a void over the entire length of the sealing material and the clip and straddles it is elastically locked to the lower end of the clip, and covers the joint of the roofing material with the joint cover, In the same manner as in the invention of item 1, when the roof material is laid, the bendable pieces of the upright pieces of the suspenders are extended upward without bending, so that the construction of the roof material is not obstructed. Can be done as before, Without hinder, there is an advantage that facilitates the construction of the roofing material on a roof.

Further, since the joint cover over which the sealing material and the clip are formed over the entire length to form a space is elastically locked to the lower end of the clip and the joint of the roof material is covered with the joint cover, The seal material is separated from the joint cover, which is radiated by the sun and cooled by cold air at night, to prevent the seal material from greatly changing its temperature, protect the seal material, and prevent deterioration of the seal material. There is an advantage that it can be avoided. Moreover, since a void is formed between the sealing material and the joint cover, rainwater does not splash on the joint between the sealing material and the roofing material, so that the inside (lower side) and the outside (upper side) of the roofing material are not exposed. There is an advantage that it is possible to prevent intrusion due to rainwater suction caused by a pressure difference between the two.

In addition, since there are provided a sealing material for performing a watertight seal over the entire length of the connection point between the two roofing materials connected by the suspenders, and a short clip for holding the sealing material, the short clip is used. By removing the sealing member, there is an advantage that the long sealing member can be removed and replaced, and it is possible to cope with aging of the sealing member.
