The present invention relates to a fastener for a roof slat material used for the present invention.

[0002]

2. Description of the Related Art As a connection structure for a roof sheet material, as shown in FIG. 19, an engaged portion 102 is provided at one end of a flat plate-shaped roof sheet material main body 101, and is engaged with the other end. Joint 1
There is known a structure in which roof plate members 104 provided with respective 03 are connected to each other by a fastener 111.

[0003] In the above-mentioned conventional connection structure of a roof plate material,
As shown in FIG. 20, the engaged portion 102 of the roof slat 104 includes a vertical piece 102a formed by bending one end of the roof slab body 101 upward at a right angle, and a vertical piece 102a. A horizontal piece 102b is formed by bending the tip of the horizontal piece outward at a right angle, and a second vertical piece 102c is formed by bending the tip of the horizontal piece 102b upward at a right angle.

Further, the engaging portion 103 of the roof plate 104
A first bent portion 103a obtained by bending the other end of the roof plate material body 101 upward at a right angle, and a substantially U-shaped upper end of the first bent portion 103a facing outward. A second bent portion 103b formed by bending the second bent portion 103b;
And a substantially inverted U-shaped third bent portion (hereinafter referred to as a cap portion) 103c connected to the upper end side of the bent portion 103b, and the free end side of the lower end of the cap portion 103c in the second Fourth bent part 10 bent at right angle toward bent part 103b
3d, and an inclined fifth bent portion 103e obtained by folding the tip of the fourth bent portion 103d.

[0005] As shown in FIG. 21, the stopper 111 has a fixing portion 111 a fixed to a roof base 201 via a waterproof sheet 202 or the like, and one side end of the fixing portion 111 a is directed upward. Upright bent portion 111b formed by being bent at right angles to the upright bent portion 111b.
b of the first locking portion 111c suspended substantially vertically from the upper end of b
And the upright bent portion 111b and the first locking portion 111
The second and third locking portions 111d and 111e are provided so as to hang downwardly so as to sandwich c.

[0008] As shown in FIG. 22, the upright bent portion 111 b of the stopper 111 and the first locking portion 11
1c, the second vertical piece 102c of the engaged portion 102 of the roof plate 101 is sandwiched between the stoppers 1c.
Eleven fixing portions 111a are fixed on the roof foundation 201 with the nails 203 via the waterproof sheet 202. Next, as shown in FIG.
When the cap portion 103c of the engaging portion 103 of FIG.
The tip of the second bent portion 103b of the engaging portion 103 comes into contact with the inclined second locking portion 111d of the stopper 111 and the third bent portion 103d of the engaging portion 103
And a continuous portion of the fourth bent portion 103e is the stopper 111
The cap portion 103c comes into contact with the third engagement portion 111e having the inclined shape of FIG.

When the cap portion 103c is further lowered by a predetermined amount, the contact between the tip of the second bent portion 103b of the engaging portion 103 and the second locking portion 111d of the stopper 111 is released, and The contact between the third bent portion of the engaging portion 103 and the continuous portion of the fourth bent portion 103e and the third engaging portion 111e of the stopper 111 is released, and the lower end of the cap portion 103c is compressed. Diameter. Then, as shown in FIG. 24, the upper surface of the second bent portion 103b is
At the lower end of the engaging portion 111d.

[0008]

By the way, the above-mentioned conventional connection structure of the roof slab has the following problems. (1) As shown in FIG. 24, the U-shaped second bent portion 10
For the first bent portion 103a below the vertical-shaped 3b is present, only the height sentence of an H ₁ of the vertical-shaped first bent portion 103a, the height of H ₂ engaging portion 103 It will be expensive. When the vertical first bent portion 103a is eliminated, the lower surface of the U-shaped second bent portion 103b hits the head 203a of the nail 203, and the roof plate 101 is moved by the roof. It floats up from the base 201 to the waterproof sheet 202. (2) The engaging portion 103 of the roof plate material 104 is
1 only, it is stopped on the roof base 201 side (the engaging portion 103 is
Is not locked to the engaged portion 102).
As shown in FIG. 19, since the stoppers 111 are partially arranged in the length direction of the adjacent portion, the stoppers 11
Between the portions 1 and 111, the engaging portion 103 is not stopped on the roof base 201 side, and thus easily rises from the roof base 201. (3) As shown in FIG. 21, the stopper 111 is formed by bending one side end of the fixing portion 111a at a right angle.
Since the engaging portion 103 is cantilevered by the bent portion 111b , when the strong load is applied, the upright first bent portion 111b may be bent at the root.

The present invention has been made to solve the above-mentioned conventional problems.
