[Industrial applications]

 TECHNICAL FIELD The present invention relates to a nut for a folding plate root used for mounting a folding roof panel on a receiving frame.

[0002]

[Prior art]

 There are various known construction structures for origami roofs, but the simplest structure and most often used is a panel in which sword bolts that are erected on the top of the receiving frame (tight frame) are laid on the receiving frame. It has a structure in which a wool packing and a washer are attached to the exposed bolt, and a tightening nut is screwed. By the way, an electric wrench is used to screw nuts when constructing a folded roof having the above structure. However, unless the nuts are first fitted, the work cannot be performed smoothly. For this reason, the first fitting of nuts is a manual work, and the subsequent fastening work is done with an electric wrench. Since this manual work itself is complicated, it has been proposed to improve the sword bolt attached to the receiving frame. As disclosed in Japanese Utility Model Publication No. 3002314, this is a sword bolt provided with a nut mounting portion.

[0003]

[Problems to be solved by the device]

 As mentioned above, when constructing a folded roof, the first fitting in the tightening operation of the tightening nut is a complicated work. Moreover, the improvement of the sword bolt does not always put the tightening nut in the optimal state for fitting, and the manufacturing of the bolt itself is troublesome. Therefore, the present invention proposes a novel folded-plate roof nut in which all the parts attached to the sword bolt are integrated and the first fitting can be easily performed.

[0004]

[Means for Solving the Problems]

 The folded roof nut according to the present invention is provided with a disc ring-shaped wool packing, a bowl-shaped washer, a nut body, and a bolt shaft accommodating portion above the nut close-fitting portion formed on the nut outer shape. It consists of a resin cap body with an umbrella-shaped washer storage section below the nut insertion section.The nut body, washer, and wool packing are stored in the cap body in this order from the inside in a laminated state. It is characterized by

[0005]

[Action]

 Since the whole is integrated, when inserted into the sword bolt that protrudes upward from the folded version roof panel, the wool packing fits outside the bolt shaft part, so the nut body and the bolt can be fitted The nuts for the origami roof are installed at various positions. Then, when the nut tight insertion part of the cap body is driven and rotated by an electric wrench, the nut body is screwed into the sword bolt and fixes the panel.

[0006]

【Example】

 Next, an embodiment of the present invention will be described. The folded roof nut shown in the embodiment is composed of a wool packing 1, a washer 2, a nut body 3 and a cap body 4. The wool packing 1 is a disc ring shape made of felt and has a folded roof. It is provided with a shaft hole 11 that can be externally inserted into a sword bolt A for fastening. The washer 2 is in the shape of a bowl having a diameter larger than that of the wool packing 1, and the edge of the central shaft hole 21 is bent downward to form a tubular portion 22, which can be externally attached to the sword bolt A. In addition, the size is such that it is press-fitted into the shaft hole 11 of the wool packing 1. The nut body 3 is an ordinary hexagonal nut and can be screwed into the sword bolt A.

The cap body 4 is made of resin and has a nut close-fitting portion 41 which is formed in the outer shape of the nut body 3 and can tightly fit the nut body 3 inside the central portion. In order to fix the folded roof panel B in a continuous manner above the nut tightly inserted portion 41 above the tightly inserted portion 41, it corresponds to the protruding length when the folded roof nut is attached to the bolt A. A bolt shaft storage portion 42 is provided, an umbrella-shaped washer storage portion 43 corresponding to the washer 2 is provided below the nut tight insertion portion 41, and the opening has a size such that the outer peripheral edge of the washer 2 is fitted therein. Therefore, the locking portions 44 are provided so as to project inwardly at 3 to 4 positions at equal intervals. Further, when the upper portion of the cap-shaped portion of the cap body 4 above the position where the locking portion 44 is formed is a notch portion 45 corresponding to the shape of the locking portion 44, it is projected inward by the upper and lower punching die molding. The locking portion 44 can be formed.

Then, the nut body 2 is attached to the nut close-fitting portion 41 of the cap body 4, and the tubular portion 22 of the washer 2 is press-fitted into the shaft hole 11 of the wool packing 1 to integrate them, and the washer 2 is It is located below the body 3, and its outer edge is locked to the locking portion 44, and all the members are integrated.

Therefore, the sword bolt A that is erected on the top of the receiving frame (tight frame) C is exposed by penetrating the panel B laid on the receiving frame C, and the exposed sword bolt A is applied to the folded roof of the present invention. A panel nut is screwed on to fix panel B. In the nut tightening work, the folded roof nut of the present invention is attached to a sword bolt A protruding upward from the folded roof panel C. When inserted, the shaft hole 11 of the wool packing 1 and the tubular portion 21 of the washer 2 are externally fitted to the shaft portion of the bolt A, so that the nut body 3 and the bolt A can be fitted to each other at a position where the present invention can be fitted. Folded roof nuts are installed. Then, when the nut tight insertion portion 41 of the cap body 4 is driven and rotated by an electric wrench, the nut body 3 is screwed onto the sword bolt A and the panel B is fixed.

Although the hexagonal nut is adopted as the nut body 3 in the above-mentioned embodiment, other square nuts can be used, and the washer, the wool packing, the nut body and the cap body can be integrated with each other in the above-mentioned embodiment. Alternatively, an adhesive may be used, or any other means may be adopted as long as it can be integrated.

[0011]

[Effect of the invention]

 As described above, according to the present invention, the disc ring-shaped wool packing, the bowl-shaped washer, the nut body, and the bolt shaft accommodating portion provided above the nut sealing portion formed on the nut outer shape are provided, and the nut sealing nut is inserted. A folded roof consisting of a resin cap body with an umbrella-shaped washer storage section underneath, and the nut body, washer, and wool packing are stored in the cap body in this order in a laminated state. With the nut for the nut, the nut body and the bolt can be fitted by simply inserting it into the sword bolt that protrudes above the folded roof panel, so it is possible to screw it with an electric wrench and tighten the panel. The installation work can now be carried out more efficiently.
