[0026] [Example 4-2] The present invention relates to a membrane structure, and in Example 4-1, the intermediate fixing body (330) comprises: a connecting pin (331) located on one side and coupled with the first fastening member (311); and a connecting rod (332) located on the other side and inserted into and fixed to the second fastening member (321).

[0027] [Example 4-3] The present invention relates to a membrane structure and, in Example 4-2, includes a position fixing means (400) located between the fastening rod (332) and the second fastening member (321) and fixing the position of the intermediate fixing body (330).

[0028] [Example 4-4] The present invention relates to a membrane structure, and in Example 4-3, the position fixing means (400) comprises: a male screw (410) formed on the outer circumference of the fastening rod (332); a nut (420) that is screw-fastened to the male screw (410); and an insert (430) that is positioned between the nut (420) and the second fastening member (321) and into which the fastening rod (332) is inserted.

[0029] [Examples 4-5] The present invention relates to a membrane structure, and in Example 4-4, the insert (430) comprises: a first insert (431) installed to contact the nut (420); and a second insert (432) partially inserted into the second fastener (321) and in contact with the first insert (431).

[0030] [Examples 4-6] The present invention relates to a membrane structure, and in Example 4-5, the first insert (431) comprises: a first support surface (431a) formed at one end and in close contact with the nut (420); and a second support surface (431b) formed on the other side and formed in a conical or spherical shape.

[0031] [Example 4-7] The present invention relates to a membrane structure, and in Example 4-6, the second insert (432) comprises: a through hole (432a) that penetrates the center and into which the fastening rod (332) is inserted; and a partial insertion projection (432b) that is partially inserted into the second fastening hole (321) on one side of the outside.

[0032] [Examples 4-8] The present invention relates to a membrane structure, and in Example 4-7, the second insert (432) includes a fastening rod angle limiting surface (432c) formed at an angle on one side of the through hole (432a).

[0033] [Example 4-9] The present invention relates to a membrane structure, and in Example 4-7, the second insert (432) includes a contact surface (432d) formed on the other side of the through hole (432a) and in contact with the second support surface (431b).

[0034] [Examples 4-10] The present invention relates to a membrane structure, and in Examples 4-5, the second insert (432) is formed with a lower strength than the first insert (431) and the second fixing body (320).

[0035] [Example 4-11] The present invention relates to a membrane structure, and in Example 4-4, the position fixing means (400) includes an anti-loosening body (440) formed on the nut (420).

[0036] [Example 4-12] The present invention relates to a membrane structure and, in Example 4-4, includes a stopper (500) coupled to the end of the fastening rod (332) to prevent the nut (420) from being separated from the male screw (410).

[0037] [Example 4-13] The present invention relates to a membrane structure, and in Example 4-4, the insert (430) includes a rubber bushing (433) inserted into the second fastener (321).

[0038] [Example 4-14] The present invention relates to a membrane structure, and in Example 4-13, the insert (430) includes a backup plate (434) installed to cover the side facing the nut (420) in the rubber bushing (433), and the backup plate (434) has a flange portion (434a) formed that protrudes along the outer edge and surrounds the outer end of the rubber bushing (433).

[0039] Examples 4-1 to 4-14 of the present invention embody the fixing part (300) and the position fixing means (400).

[0040] As illustrated in FIG. 4, the second fixing member (320) may be composed of a plate joined to the end of the crossbar (120) of the support frame (100). The intermediate fixing member (330) is connected to the first fastening member (311) by a connecting pin (331), and a fastening rod (332) passes through the second fastening member (321). At one end of the fastening rod (332), a 'C'-shaped jaw (332a) is formed for joining the connecting pin (331) and the fastening rod (332).

[0041] As illustrated in FIGS. 7 and 8, the position fixing means (400) fixes the intermediate fixing body (330) to the second fixing body (320) and supports the intermediate fixing body (330) so that it can move up, down, left, and right.

[0042] As illustrated in FIGS. 5 and 6, in the insert (430), the first support surface (431a) of the first insert (431) is in surface contact with the nut (420), and the second support surface (431b) is formed in a conical or spherical shape and is in line contact or surface contact with the contact surface (432d) of the second insert (432). At this time, due to the spherical shape of the second support surface (431b), the load acting on the contact surface (432d) acts in the normal direction of the second support surface (431b), thereby dispersing the stress.

[0043] The second insert (432) has lower strength than the first insert (431) and the second fixing body (320), and thus fails before the first insert (431) and the second fixing body (320) due to fatigue load. The membrane (200) is continuously exposed to wind, and as a result, an axial fatigue load is applied to the intermediate fixing body (330). This fatigue load is also applied to the first insert (431), the second insert (432), and the second fixing body (320). If the strength of the second insert (432) is relatively lower than that of the first insert (431) and the second fixing body (320), it results in failure before the first insert due to fatigue load. Therefore, the second insert (432) has the effect of protecting the entire structure. The damaged second insert (432) can be easily replaced at a low cost.

[0044] The fastening rod angle limiting surface (432c) is an inclined surface of the inner wall of the penetration hole (432a) that limits the angle of the fastening rod (332). The partial insertion projection (432b) allows the second insert (432) to be stably fixed to the second fixing body (320) as it is inserted into the second fastening hole (321).

[0045] As shown in FIG. 9, the anti-loosening body (440) is composed of a double nut that is fastened in contact with the nut (420) to prevent the nut (420) from loosening. The stopper (500) is formed in the shape of a plate and can be mounted on the fastening rod (332) by means of a bolt or welding. The stopper (500) is formed to protrude outward from the fastening rod (332) to prevent the nut (420) from loosening from the male screw (410) and detaching from the fastening rod (332).

[0046] As illustrated in FIG. 10, the insert (430) may include a rubber bushing (433) and a backup plate (434). In this case, the backup plate (434) prevents damage to the rubber bushing (433). A flange portion (434a) formed on the backup plate (434) contacts the second fixing body (320) when the angle of the fastening rod (332) is significantly tilted, thereby limiting the angle of the fastening rod (332).

[0047] [Example 5-1] The present invention relates to a membrane structure, and in Example 4-1, the first fixing body (310) comprises a lower fitting plate (312) and an upper fitting plate (313) joined to face each other with the membrane (200) in between.

[0048] [Example 5-2] The present invention relates to a membrane structure, and in Example 5-1, the first fixing body (310) comprises a plurality of connecting bolts (314) and connecting nuts (315) that connect the lower fitting plate (312) and the upper fitting plate (313).

[0049] Examples 5-1 to 5-2 of the present invention embody the first fixed body (310).

[0050] As illustrated in FIG. 4, the first fixing member (310) places the edge of the membrane (200) between the lower fitting plate (312) and the upper fitting plate (313) and fixes it by compression. The first fastening member (311) is formed on the lower fitting plate (312), so that the lower fitting plate (312) is rotatably connected to the connecting pin (331). A plurality of connecting bolts (314) and a plurality of connecting nuts (315) are arranged at equal intervals along the direction in which the lower fitting plate (312) and the upper fitting plate (313) extend to firmly fix the lower fitting plate (312), the upper fitting plate (313), and the membrane (200).
