[0037] Embodiment 1

[0038] In order to solve the problem that when two mold materials are spliced in the prior art, the complete separation and splicing of adjacent two aluminum alloy pressing plates will cause a joint where the aluminum alloy pressing plate cannot contact the mold material. Although a sealing strip will be formed by using sealant for subsequent sealing, due to the poor force-bearing at the joint, it is also likely to cause a poor sealing effect of the mold material corresponding to the joint, resulting in the penetration of moisture and air. As Figures 1-5 shown, a membrane material connector for an air-supported membrane structure is provided, which includes an aluminum alloy pressing plate 2 with an installation hole 1 provided at the splicing position of two mold materials, bolts 3 and nuts 4 that cooperate with the installation hole 1 on the aluminum alloy pressing plate 2 and the mold material. At the adjacent ends of two adjacent aluminum alloy pressing plates 2, a groove 5 with an open end is provided on one aluminum alloy pressing plate 2, and a convex block 6 that is butt-jointed and rotationally cooperates with the groove 5 is provided on the other aluminum alloy pressing plate 2.

[0039] In practice, the aluminum alloy pressing plate is usually installed on the outside of the mold material. The bolts pass through the holes on the two spliced mold materials and cooperate with the nuts through the aluminum alloy pressing plate on the outside for fixation. After fixing one aluminum alloy pressing plate, the convex block 6 or the groove 5 on the adjacent aluminum alloy pressing plate is made to cooperate with the groove 5 or the convex block 6 on the fixed adjacent aluminum alloy pressing plate, and the bolts pass through the holes on the two spliced mold materials and cooperate with the nuts through the aluminum alloy pressing plate on the outside for fixation. Of course, in practice, aluminum alloy pressing plates can also be provided on both the inside and the outside of the mold material. In this embodiment, when two mold materials are spliced, by providing grooves and convex blocks on the aluminum alloy pressing plate, the crosswise cooperation at the ends between two adjacent aluminum alloy pressing plates is realized, effectively avoiding the joint where the adjacent two aluminum alloy pressing plates are completely separated and cannot contact the mold material. At the same time, since the ends of the adjacent two aluminum alloy pressing plates are crosswise cooperated through the grooves and convex blocks, the sealant-sealed gaps between the grooves and the convex blocks are beneficial to providing uniform force support for the sealing strip formed by the sealant, thereby improving the sealing performance and effectively reducing the possibility of moisture and air penetration.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, along the length direction of the aluminum alloy pressing plate 2, at least one elastic reset structure 7 in contact with the mold material is provided on the aluminum alloy pressing plate 2 corresponding to the groove 5 or / and the convex block 6 or / and the connection part of the convex block 6 and the aluminum alloy pressing plate 2, and the number of settings is determined according to requirements. This embodiment enables the aluminum alloy pressing plate to be applicable to different external conditions and internal environments, that is, when the end of the aluminum alloy pressing plate is separated from the mold material under conditions such as temperature change and wind force, displacement compensation can be carried out through the reset or buffering action of the elastic reset structure to maintain the close contact between the aluminum alloy pressing plate and the mold material, that is, a force is applied to the mold material at the splicing part through the thrust of the elastic reset structure for sealing to improve the sealing performance.

[0042] Embodiment 3

[0043] On the basis of Embodiment 2, the elastic reset structure 7 includes a spring 8 provided on the aluminum alloy pressing plate 2 or / and the convex block 6 or / and the connection part of the convex block 6 and the aluminum alloy pressing plate 2, and a rubber sleeve 9 sleeved outside the spring 8 and provided on the aluminum alloy pressing plate 2 or / and the convex block 6 or / and the connection part of the convex block 6 and the aluminum alloy pressing plate 2. The elastic reset structure provides sufficient elasticity through the combination of the spring and the rubber sleeve to compensate for the displacement between the end of the aluminum alloy pressing plate and the mold material, so as to prevent the end of the pressing plate from being completely separated from the mold material. At the same time, the rubber sleeve can prevent the subsequent filled sealant from affecting the spring and can also effectively prevent the spring from directly contacting the mold material and wearing the mold material. Of course, in practice, it is not excluded that other structures may also be used. The spring 8 and the rubber sleeve 9 can be fixedly connected or movably matched with the connection part of the aluminum alloy pressing plate 2 or / and the convex block 6 or / and the convex block 6 and the aluminum alloy pressing plate 2.

[0044] Embodiment 4

[0045] On the basis of Embodiment 3, a rubber rod 10 that is stressed and compressed and releases pressure to reset is provided on the connection part of the aluminum alloy pressing plate 2 or / and the convex block 6 or / and the convex block 6 and the aluminum alloy pressing plate 2, the spring 8 is sleeved outside the rubber rod 10, and the rubber rod 10 is connected to the rubber sleeve 9. The purpose of setting the rubber rod is to facilitate the offset limit when the spring is compressed and can also cooperate with the spring to compensate for the displacement between the end of the aluminum alloy pressing plate and the mold material.

[0046] Embodiment 5

[0047] Based on Embodiment 4, threaded holes 11 are provided on the aluminum alloy pressing plate 2 and / or the bump 6 and / or the connection between the bump 6 and the aluminum alloy pressing plate 2; the elastic reset structure 7 further includes a T-shaped threaded member 12 that mates with the threaded holes 11, and the rubber rod 10, the spring 8, and the rubber sleeve 9 are arranged on the aluminum alloy pressing plate 2 and / or the bump 6 and / or the connection between the bump 6 and the aluminum alloy pressing plate 2 through the T-shaped threaded member 12. This method is a way that the spring 8 and the rubber sleeve 9 can be movably connected to the aluminum alloy pressing plate 2 and / or the bump 6 and / or the connection between the bump 6 and the aluminum alloy pressing plate 2, aiming to facilitate the setting of the elastic reset member according to requirements, which can not only save costs but also be beneficial for maintenance.

[0048] Embodiment 6

[0049] Based on Embodiment 5, on the side that mates with the mold material, a rubber protection layer 13 that mates with the mold material is provided on the aluminum alloy pressing plate 2. The rubber protection layer can protect the mold material from direct contact and wear by the aluminum alloy pressing plate or the bump, and extend the service life of the mold material.

[0050] Embodiment 7

[0051] Based on Embodiment 6, a sealing gasket 14 that mates with the film material and the aluminum alloy pressing plate 2 is sleeved on the T-shaped threaded member 12. The setting of the sealing gasket can effectively avoid the problem of leakage at the installation hole position.

[0052] In summary, the telescopic distance, the reset force, etc. of the elastic reset structure are set according to practical requirements.
