Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a tightening structure in a tightening enclosure that makes tightening simple and reliable and has excellent strength.

(Prior Art) Conventionally, the locking structure of this type of locking enclosure has been constructed using a main building 1 such as a beam, as shown in FIGS. 5 to 7.
A corrugated tight frame 3 that corresponds to the uneven shape of the plate materials 2, 2... for the fastening outer enclosure is fixed to the upper surface by welding or screwing, and the corrugated step portion 3a of the tight frame 3 is A fastening fitting 4 is fixed with a bolt 5 and a nut 5a. Inside the upper end of this fastening fitting 4, an arc-shaped inner frame part 6, which is integrally formed by standing up from the edge of one fastening outer enclosure plate material, and on the outside, the other fastening outer enclosure plate material 2. The arcuate outer ribs 7 that are integrally molded are made to stand up on the edges of the inner and outer ribs 7, and the folded piece 4a at the upper end of the fastening fitting 4 is fitted between the inner and outer ribs 6 and 7. The tip edge 7a of the outer ridge part 7 is folded back and swaged downward inside the inner ridge part 6.

In addition, in a roof plate in which rising side plates are provided on both sides of the bottom plate, outward horizontal pieces are connected to the upper ends of the side plates, and a ridge is formed at the end of the horizontal pieces, a protrusion for locking is provided at the upper part of the rising side plates. There was a folded plate-type roof plate that formed a part (see Utility Model Application Publication No. 123810/1983).

Furthermore, the upper ends of both sides of the elongated groove having a flat bottom and a rectangular cross section are bent outward to form a groove, and then a rising portion extending linearly diagonally outward is formed. A long piece having an upper end extending parallel to the bottom to form an overlapping part having an inwardly bent groove approximately at the center thereof, and a hanging part by extending these side edges diagonally downward. The metal plates are arranged one after another on the beam, the overlapped parts of each metal plate are overlapped, and the overlapped parts and the joint part between the bottom and the beam are connected with respective fixing devices, and the upper surfaces of the metal plates are connected. Each had a roof covered with a cap (see Utility Model Publication No. 15177-1977).

(Problems to be Solved by the Invention) As shown in FIG. 6, the locking structure of the conventional locking enclosure is such that the outer locking portion 7 is brought into close contact with the outside of the inner locking portion 6. Otherwise, the tightening cannot be performed reliably, so the close contact work requires skill and is not easy.

If this tight fitting work is not performed reliably, for example, if the tightening is performed with a gap 8 between the inner rib part 6 and the outer rib part 7 as shown in FIG. As shown in Fig. 9, the outer ridge portion 7 could not be brought into close contact with the inner ridge portion 6, and the tip edge 7a of the outer ridge portion 7 could not be folded back to the inner lower side of the inner ridge portion 6 sufficiently, resulting in the strength not being as expected. There is a problem that you will not be able to obtain
Moreover, there was a problem in that the damage to the material increased.

In addition, although the folded plate type roofing plate disclosed in the above-mentioned Japanese Utility Model Publication No. 53-123810 has the effect of being able to be installed without using hangers, it requires a separate tight frame. Moreover, it is necessary to form a claw piece that fits into the protrusion, which requires time and effort.

Furthermore, in the case of the roof disclosed in Japanese Utility Model Publication No. 46-15177, since the connecting portions are covered with caps, the overall strength is increased, but at the same time, the connecting portions do not wobble. However, since connecting holes for screwing the screws must be opened in the rising portion and the hanging portion and the cap must be attached to the cap, it is difficult to determine the position of the connecting holes. In addition to being time-consuming, there was a risk of water leaking from the connecting hole.

The present invention was developed in view of these conventional problems and to solve them. It simplifies the work of adhering the inner and outer parts together, ensures tightness, and improves strength. The object of the present invention is to provide an excellent locking structure in a locking enclosure.
