The air film rope edge 5 at the lower end of the air film 6 is passed through the limiting perforation 31 from one side of the limiting perforation 31, and the air film 6 at the upper end of the air film rope edge 5 extends upward along the opening of the limiting perforation 31 to the outside of the connecting clamp 3.

[0029] Based on the above structure, when the air membrane 6 needs to be fixed, it is only necessary to pass one side of the air membrane rope edge 5 into the limiting perforation 31, so that the air membrane rope edge 5 can be clamped in the connecting clamp 3, and the connection operation between the air membrane 6 and the foundation is completed. The operation is simple and quick. The use of this connection structure can shorten the construction period of installing the air membrane 6, reduce labor, and there is no need to punch holes on the edge of the membrane material, so that the installed membrane material can be recycled. At the same time, compared with simply using the friction between the wood and the membrane material for fixing, the connection is more stable, and the air membrane 6 will not be damaged. The actual use effect is excellent.

[0030] Furthermore, the connection structure includes a bolt installation groove 32, a bottom opening 33, a connection hole 21 and a connection member, wherein the bolt installation groove 32 is provided at the lower part of the connection clamp 3 and also passes through the connection clamp 3 transversely;

[0031] The bottom opening 33 is formed at the lower end of the bolt installation groove 32 and connects the bolt installation groove 32 with the outside of the lower end of the connecting clamp 3; a plurality of connecting holes 21 are formed and evenly distributed at the upper end of the beam steel 2, and the plurality of connecting holes 21 vertically penetrate the top wall of the beam steel 2; the connecting member sequentially penetrates the connecting holes 21 and the bottom opening 33 and detachably fixes the lower end of the connecting clamp 3 to the upper end of the beam steel 2;

[0032] The connecting part includes a connecting bolt 4, which is slidably embedded in the bolt mounting groove 32 from one side of the bottom opening 33. The nut of the connecting bolt 4 is located in the bolt mounting groove 32 and the nut diameter of the connecting bolt 4 is larger than the width of the bottom opening 33. The lower end of the stud of the connecting bolt 4 passes through the bottom opening 33 and the connecting hole 21 in sequence and is located on the inner side of the beam steel 2. The nut of the connecting bolt 4 is screwed on the stud of the connecting bolt 4 and the upper end is tightly pressed against the inner top wall of the beam steel 2.

[0033] Through the setting of the connecting structure, when it is necessary to install the connecting clamp 3, the staff only needs to slide the nut of the connecting bolt 4 from one side of the bolt installation groove 32 into the bolt installation groove 32, and at the same time make the stud part of the connecting bolt 4 slide through the bottom opening 33, then insert the lower end of the stud of the connecting bolt 4 into the connecting hole 21 pre-opened on the beam steel 2, and screw the nut of the connecting bolt 4 on the stud of the connecting bolt 4, so that the upper end of the nut of the connecting bolt 4 is tightly against the inner top wall of the beam steel 2, and the installation operation of the connecting clamp 3 can be completed. The installation is convenient, and the holes, grooves and connecting holes 21 on the connecting clamp 3 are all reserved or pre-opened holes and grooves, so there is no need to drill holes on site, and the construction is more convenient and quick; at the same time, the installed connecting clamp 3 can be disassembled by the reverse step operation, so as to facilitate the disassembly and maintenance of the connecting clamp 3, and it is more convenient and quick to use.

[0034] Furthermore, an anti-skid gasket 7 is fixed to the inner wall of the limiting perforation 31.

At least one anti-skid gasket 7 is fixed, and the inner side of the anti-skid gasket 7 has an interference fit with the outer side of the air membrane rope edge 5. Through the setting of the anti-skid gasket 7, the friction between the inner wall of the limiting perforation 31 and the outer surface of the air membrane rope edge 5 can be enhanced, thereby ensuring that the air membrane rope edge 5 is more stable after being inserted into the limiting perforation 31, thereby more effectively avoiding the displacement of the air membrane rope edge 5 and causing the displacement of the air membrane 6, thereby avoiding the damage caused by the mutual friction between the air membrane 6 and the connecting clip 3, which can extend the service life of the air membrane 6 to a certain extent and reduce the maintenance cost of the air membrane hall.

[0035] Furthermore, a waterproof structure is provided at the upper end of the connecting clamp 3, and the waterproof structure can make the excess rainwater automatically overflow from the outside when the rainwater enters the limiting perforation 31 from the outside;

[0036] The waterproof structure includes a short wall 34 and a tall wall 35 . The upper end of the short wall 34 is lower than the upper end of the tall wall 35 . A top opening 36 opened to the outside is formed between the short wall 34 and the tall wall 35 .

[0037] A top opening 36 open to the outside is formed by the short wall 34 and the high wall 35, so that after external rainwater enters the limiting perforation 31, when the rainwater fills the limiting perforation 31, the excess rainwater automatically overflows to the outside from the top opening 36 located on the side of the short wall 34, which can ensure that rainwater will not flow back into the air-film pavilion from the limiting perforation 31, and can also ensure that the air membrane 6 will not overflow, thereby playing a good waterproof role.

[0038] It should be noted that in order to prevent rainwater from staying in the limiting perforation 31 and causing corrosion or other damage to the air film 6 and the air film rope edge 5 at the lower end, a downwardly inclined inclined hole (not shown in the figure) can also be opened on the side wall of the connecting clamp 3 on the side of the short wall 34. The upper end of the inclined hole extends to the bottom of the limiting perforation 31 and is connected to the limiting perforation 31, and the lower end of the inclined hole passes through the side wall of the connecting clamp 3 on the side of the short wall 34 to connect to the outside, so that rainwater poured into the limiting perforation 31 can flow out from the inclined hole after the pouring stops, thereby preventing rainwater from remaining in the limiting perforation 31 and causing corrosion or other damage to the air film 6 and the air film rope edge 5 at the lower end. Combined with the arrangement of the short wall 34 and the high wall 35, a better waterproof effect can be achieved.

The installation is convenient, and the holes, grooves and connecting holes 21 on the connecting clamp 3 are all reserved or pre-opened holes and grooves, so there is no need to drill holes on site, and the construction is simple and convenient. It is more convenient and quicker; at the same time, the installed connecting clip 3 can also be disassembled by the reverse step operation, so as to facilitate the disassembly and maintenance of the connecting clip 3. After that, only one side of the air film rope edge 5 needs to be passed through the limiting perforation 31, so that the air film rope edge 5 can be clamped in the connecting clip 3 to complete the connection operation between the air film 6 and the foundation. The operation is simple and quick. The use of this connection structure can shorten the construction period of installing the air film 6 and reduce labor. There is no need to punch holes on the edge of the membrane material, so that the installed membrane material can be recycled. At the same time, compared with simply using the friction between the wood and the membrane material for fixing, the connection is more stable, and the air film 6 will not be damaged. The actual use effect is excellent.
