[0002]

2. Description of the Related Art Conventionally, as a method of introducing tension in a film material in a film structure of this type, for example, a conventional example as shown in FIG. 8 has been known. That is, on the beam 40 of the membrane structure,
The spread rubber 41 is arranged in advance, and then, when the film is spread on the film structure, the clamp clamp 42 is attached to the film end 44 of the film material 43.
Attach to Then, the wire end 45 is gradually pulled in the direction of the arrow by the wire tensioner 45 attached to the Tsuka clamp 42, and the film hole 46 formed in the film end 44 is
It is inserted into a bolt 47 provided on the beam 40 of the membrane structure. Furthermore, by attaching a film end presser and a cover rubber to the film end 44 and tightening the nut to the bolt 47,
This is a method for introducing the initial tension of the membrane material.

Further, as another conventional tension introducing method for the membrane material, a tension introducing mechanism used in the tension introducing method for the film-like body disclosed in Japanese Patent Publication No. 5-66465 is a conventional example. Known as.

The tension introducing mechanism of this conventional example is shown in FIGS. 7 (A), 7 (B) and 7 (C). First, FIG. 7A is a plan view showing the first pressing plate 1 which constitutes a part of the tension introducing mechanism, and the first pressing plate 1 is provided with a plurality of bolt holes 2. . The bolt holes 2 are arranged in a line so as to be centered at a position offset to the one edge 1a side of the first pressing plate 1.

Next, FIG. 7B is a cross-sectional view showing the main part of the tension introducing mechanism 3 provided on the beam of the membrane structure.
A film material 5 is sandwiched between the first pressing plate 1 and the second pressing plate 4, and the film material 5 is fastened and fixed by a bolt 6 on the first pressing plate 1. The edge of the film material 5 is folded back to form a bag portion 7, and a rope 8 is inserted into the bag portion 7 to form a stop portion 9. The stop portion 9 forms the first pressing plate 1
Is locked to the edge 1a of the.

To re-introduce the tension to the tension introducing mechanism 3, the bolt 6 is removed to remove the first pressing plate 1, and then the direction of the first pressing plate 1 is changed to press the film material 5 again. Put in. At this time, the other end portion 1b of the first pressing plate 1 presses the stop portion 9 of the film material 5 such that the stop portion 9 is locked, and is fixed again with the bolt 6 (see FIG. 7C).

By doing so, the distance D from the bolt hole 2 of the first pressing plate 1 to the one end 1a
It is possible to introduce the re-tension of the film material by the difference between the distance D1 and the distance D2 to the other end 1b.

[0008]

There is a problem in that it is impossible to introduce tension of a proper length other than the distance.

Therefore, in the tension introducing method and the tension introducing mechanism in the conventional example, the initial tension and the re-tension of the membrane material are simply introduced to improve the workability, and the tension is appropriate for the relaxation state of the membrane material. There is a problem that must be solved in order to introduce a re-tension of a different length.
