Description

  The present invention relates to a tight frame for fixing a folded plate to a roof base and a folded plate roof formed using the tight frame.

  Conventionally, a folded plate roof is formed by fixing a plurality of folded plates to a roof base with a tight frame. Usually, a hanger is used to connect the folded plate and the tight frame. However, as shown in FIG. 7, in addition to the hanger, a device that connects the folded plate and the tight frame has been proposed (for example, , See Patent Document 1). The tight frame 50 used for this has support parts 51 having a substantially inverted U-shaped cross section, and is formed by providing fixed pieces 52 protruding outward at both lower ends of the support part 51. The support 51 is provided with a locking body 58. The locking body 58 is disposed so as to span both sides of the support portion 51 and is formed to be slidable to the left and right with respect to the support portion 51. Further, both ends of the locking body 58 are formed as locking portions 53, and the locking portions 53 protrude from the outer surface of the support portion 51. On the other hand, the folded plate 54 is formed to have a flat trough 55 and crests 56, 56 projecting obliquely upward from both sides thereof. A locked portion 57 that protrudes to the side is projected.

  In forming the folded plate roof, a plurality of tight frames 50, 50... Are arranged and fixed on the roof base 59, and the folded plate 54 is fitted between the adjacent tight frames 50, 50. . At this time, the locked portion 57 of the folded plate 54 is locked under the locking portion 53 of the support portion 51 of the tight frame 50 to connect the tight frame 50 and the folded plate 54. In this way, after arranging the plurality of folded plates 54, 54..., The end portions of the crest portions 56, 56 of the adjacent folded plates 54, 54 on the upper side of the support portion 51 are joined by brazing. Thus, a folded plate roof can be formed.

However, in the above case, the locked portion 57 of the folded plate 54 must be locked to the locking portion 53 of the support portion 51 while the folded plate 54 is elastically deformed, and the tight frame 50 and the folded plate 54 are attached to each other. A strong force is required for the connection, and the folded plate 54 may be plastically deformed or scratched, which may reduce the appearance and waterproofness of the folded plate roof. Further, even after the folded plate 54 is constructed, the locking body 58 is slidable without being fixed, so that the locking body 58 moves carelessly and the locking portion 53 and the locked portion 57 The lock is released and the folded plate 54 is easily detached from the tight frame 50, and there is a risk of insufficient strength against negative pressure.

Since the folding plate 3 is disposed on the folding plate 3 and then the locking body 9 is slid and the locked portion 5 of the folding plate 3 is locked to the locking piece 10, the folding plate 3 is elastically deformed with a strong force. The locking piece 10 and the locked portion 5 can be locked without any trouble and can be easily constructed. Moreover, the operation pieces 14 and 14 can be clamped by the pressing piece 42, the pressing portion 26, and the fitted portion 25 of the fitting portion 24 of the mountain half 1 and 1 that are joined by tightening. Thus, inadvertent slide movement of the locking body 9 after construction of the folded plate 3 can be prevented. Accordingly, it is possible to prevent the connection between the locking piece 10 of the locking body 9 and the locked portion 5 of the folded plate 3 from being released, and to prevent the connection strength between the tight frame A and the folded plate 3 from being lowered. Thus, it is possible to prevent a lack of strength against negative pressure.

  Various shapes can be employed for the fitting portion 24 and the fitted portion 25 of the folded plate 3, for example, as shown in FIG. 6. The fitting portion 24 includes a pressing piece 42 protruding upward from the top piece 23, an upper piece 43 protruding from the upper end of the holding piece 42 on the opposite side of the top piece 23, and a vertical direction from the upper piece 43. It is comprised from the bending piece 45 protruding toward the downward direction, and the clamping piece 46 protruding toward the opposite side to the pressing piece 42 from the front-end | tip of the bending piece 45. FIG. Further, the fitted portion 25 is formed in an approximately L-shaped cross section that protrudes upward from the end portion of the top piece 23.

  Then, in the same manner as described above, after the fitted portion 25 of the peak half 1b of the folded plate 3A is disposed in contact with the operation piece 14 of the locking body 9B provided on the frame body 7, FIG. As shown in (a), the fitting portion 24 of the mountain half 1a closer to the existing folded plate 3A of the newly folded folding plate 3B is connected to the mountain half 1b of the existing folded plate 3A. The fitting portion 25 and the engaging pieces 9A and 9B are fitted into the operation pieces 14 and 14 from above, and inside the fitting portion 24 of the folded plate 3B, the fitted portion 25 of the folded plate 3A and both The operation pieces 14 and 14 of the locking bodies 9A and 9B are positioned, and the pressing piece 42 of the fitting portion 24 of the folded plate 3B is brought into contact with the operation piece 14 of the one locking body 9A. Thereafter, as shown by an arrow A in FIG. 6B, the bending piece 45 is bent while pressing the holding piece 46 and the pressing piece 42 of the fitting portion 24 of the folded plate 3B so as to approach each other. Thus, the operation pieces 14, 14 and 14 between the holding piece 46 and the pressing piece 42 are joined by joining the peak half 1b of the folded plate 3A and the peak half 1a of the folded plate 3B by clamping. The crest portion 6 is formed by connecting the crest half 1b of the adjacent folded plate 3A and the crest half 1a of the folded plate 3B while sandwiching the fitted portion 25. In addition, due to the tightening, the operating piece 14 of one locking body 9B is pressed from the side by the fitted portion 25 of the one folded plate 3A, and the locking body 9B is folded on the other side. It slides in a direction approaching the plate 3B, and the locking piece 10 of the locking body 9B is positioned above the locked portion 5 of the folded plate 3B, and the operation piece of the other locking body 9A. 14 is pressed from the side by the pressing piece 42 of the other folded plate 3B, and the locking body 9A slides in a direction approaching the one folded plate 3A, and the upper side of the locked portion 5 of the folded plate 3A. Thus, the locking piece 10 of the locking body 9A is positioned. In this manner, the locking bodies 9A and 9B are slid in opposite directions in conjunction with the above-described tightening operation, whereby the locking pieces 10 of the locking bodies 9A and 9B are moved from the side portion 11 of the frame body 7. It will be in the state which protruded greatly, and each to-be-latched part 5 of folding plate 3A, 3B will be latched by the lower side of this latching piece 10. FIG.
