った。[0001] The present invention relates to a gas seal film made of rubber, resin and cloth, which is an important component of a diaphragm type gas holder generally called a Wiggins type. The size of the gas seal film used for the diaphragm type gas holder is as follows: a small diameter φD of FIG. 1 has a diameter of 6 m, a height of 4 m, and a large diameter has a diameter of 60 m and a height of about 50 m.
In order to form this gas seal film, a large number of the following materials must be added and molded into a desired shape. FIG. 1 is a schematic sectional view showing the principle of a diaphragm-type gas holder, in which a piston 1, an outer frame 3, and a gas seal film 2 formed by folding a cylindrical sheet are attached to the cylinder 1, the outer frame 3, and an extension thereof. Although not shown, gas is supplied from outside to the space A surrounded by them, and the weight of the piston 1 and the weight for pressure adjustment applied by the rope via the pulleys 4-1, 4-2, and 4-3. The weight 5 allows the pressure in the space A to be constantly kept constant. However, the gas seal film 2 made of an elastic material allows the piston 1 to freely move up and down, and The volume is variable. The gas seal film 2 can be formed from a single sheet of rubber and resin to exhibit its function, but it needs to be reinforced with fibers from the viewpoint of required physical strength and durability. As shown in FIG. 2 (a), the small diameter portion of the mounted hollow straight conical cylindrical body (hereinafter referred to as a conical cylindrical body) 2-1 is folded inward as shown in FIG. The frame 3 is attached directly to the outer frame for simplicity of illustration, but is generally attached to an extended portion of the outer frame from the wall or floor. As shown in FIG.
By having the folded portion B of the shape, the piston 1 can be moved up and down freely, and the conical cylindrical body prevents interference between the gas seal films when the cylinder moves up and down. In order to have strength against the internal pressure in the space A, the bottom of the inverted U is prevented from being extended upward in the figure, and in the circumferential direction, the piston is allowed to move up and down more freely. In addition, since it is necessary to have elasticity in rubber elasticity, the conventional method uses a woven cloth (hereinafter referred to as a woven cloth) 6 glued with the synthetic rubber shown in FIG. is cut in the width W in the bias direction (bias angle, about θ = 45 degrees) of θ to obtain cut pieces 6-1, 6-2,...
In (b), the cutting pieces 6-1, 6-2,...
Get A. Next, in FIG.
Is cut in accordance with the length L of the slope of the cylindrical body shown in FIG. 2 to obtain a cut cloth 6-B of FIG. 3-A (d). Then, in FIG. The dotted line (A) of -B is cut to obtain a trapezoidal shape, molding material cloth 6-C. This molding material cloth 6
In FIG. 4A, the −C group is joined with a plurality of 6-Cs at the joining group C2 to form the fan-formed body 6-D of FIG. 4A. The fan-forming body 6-D is a cylindrical body 2 shown in FIG.
It can also be said to be a shape developed from -1. By joining both ends of the fan-formed body 6-D, the conical cylindrical body 2-1 of FIG.
Is obtained. In the above-mentioned conventional method, the above-mentioned joint group C1, C2
And the molding process is difficult, the risk of gas leakage is very high, and there is a problem in terms of durability.

久性の点で優れたガスシール膜を形成する事が出来る。The present invention has been intensively studied in order to solve the above-mentioned problems. The gas sealing film 2 is made of synthetic rubber and resin and has elasticity. After weaving, the woven fabric is woven using a crimped yarn as the weft. Although it is obtained, by applying an adhesive treatment to this woven cloth as necessary, and using a paste-treated woven cloth (hereinafter referred to as an elastic cloth) 7 having a stretched property,
2 (b) is obtained. In FIG. 3B, the conical cylindrical body 2-2 is formed by rotating the stretchable cloth 7 at right angles to the longitudinal direction of the conical cylindrical body 2-2 so as to have the length of the slope L of the conical cylindrical body 2-2. Cut into pieces 7-1, 7-2 ...
・ ・ Is obtained. Next, the cut pieces 7-1, 7-2,... Cut in FIG. 3-B (b) are joined together by overlap joining in the joining group C3 so that the width direction becomes L.
A band-shaped cloth 7-A was formed, and this was cut to the same (C) length of S to form the same (D) cut piece 7-B, and then the same (D).
In this case, the dotted line portion (i) of the cut cloth 7-B is cut to obtain a trapezoidal, molding material cloth 7-C. This molding material cloth 7-C
Are joined in the joining portion group C4 to obtain the fan-formed body 7-D of FIG. 4 (b).
The conical cylindrical body 2-2 of (b) is obtained. On the other hand, by taking advantage of the elasticity of the elastic cloth 7, the cut cloth 7 -B in which the cutting process of the dotted line (i) of the trapezoidal molding material cloth 7 -C in FIG. Joined at joint C5,
The hollow cylindrical body 2-3 shown in FIG. 2 (c) can be formed as a rectangular molded cloth 7-E shown in FIG. 4 (c) and joined at both ends to be used as a gas seal film. This hollow cylindrical body 2-
The shape of No. 3 is simple and excellent in workability and reliability. As described above, in the conventional method, much work is required in the processing stage of the molding material, whereas the present invention is a simpler processing method. For example, the cutting / joining process of the material of the conventional method is shown in FIG.
Therefore, oblique cutting is required for the right-angle cutting / joining of FIGS. 3-B (a), (b), (c), and (d) of the present invention. A major drawback is that many joints C1 and C2 are required in terms of reliability.
Further, the conventional band-shaped cloth 6-A has a relatively small elongation in the length direction as compared with the band-shaped cloth 7-A of the present invention, and the conical cylindrical body (straight-mounted conical cylindrical body) shown in FIG. It is necessary to increase the angle, so in the development of the conical cylindrical body in FIG.
The fan-forming body 6-D of the conventional type shown in FIG.
It is necessary to reduce the radius R of the sector in comparison with the sector molding 7-D of the present invention, and in order to form the sector more smoothly, the width W of the molding material cloth 6-C is reduced to a certain width. Need to be performed, and the number of required sheets naturally increases. As a result, the number of joints of the material becomes extremely large, and the number of joints C1, C2 becomes extremely large in the conical cylindrical body 2-1 forming the gas seal film 2, which makes molding difficult and difficult. The risk of gas leakage is very high. On the other hand, the method of the present invention is simple, and the slope length L of the conical cylindrical body 2-2 in FIG.
Irrespective of the size of the elastic cloth 7, it is possible to cut freely from the longitudinal direction of the elastic cloth 7, and because the excellent elasticity of the elastic cloth can increase the interval between the joints in the circumferential direction of the conical tubular body, Can be reduced very much. By the way, in comparison with the conventional method, the method of the present invention has the number of joints of 1/10 or less (depending on the size of the gas seal film, and the larger the size, the larger the ratio). By reducing the number of joints, it is possible to form a gas seal film that is excellent in gas leakage prevention, safety, and durability.
