Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figure 1-5 The utility model provides a technical solution: a unit assembled ETFE membrane structure, comprising:
[0027] A support layer, an ETFE film 1, and a metal frame, wherein the ETFE film 1 is arranged on the outer surface of the support layer, and the metal frame is arranged around the support layer;
[0028] A plurality of evenly distributed connecting pieces 9 are fixedly connected to the side of the supporting layer, and the connecting piece 9 is hot-melt connected to the side of the ETFE film 1, and a mounting tube 8 is fixedly connected to the end of the connecting piece 9, and the mounting tube 8 passes through the metal frame. Two symmetrically distributed sliding cavities 12 are provided inside the mounting tube 8, and balls 10 are slidably connected in the sliding cavities 12, and the balls 10 are against the outer peripheral surface of the metal frame. When connecting with the metal frame, the mounting tube 8 passes through the metal frame so that the balls 10 arranged in the mounting tube 8 are stuck on the outside of the metal frame, and the ETFE film 1 is fixed. The ETFE film 1 will not be damaged during installation, and the overall sealing of the ETFE film structure can be improved, and leakage of the ETFE film structure after long-term use can be prevented, thereby improving the sealing performance of the structure.
[0029] like Figure 1-5 As shown, a sliding groove 13 is provided inside the mounting tube 8, a threaded groove 14 is provided inside the sliding groove 13, an extrusion pin 16 is slidably connected inside the sliding groove 13, a threaded block 15 is fixedly connected to the end of the extrusion pin 16, the threaded groove 14 is threadedly connected to the threaded block 15, and the threaded block 15 cooperates with the threaded groove 14 to fix the extrusion pin 16 inside the mounting tube 8, continuously extruding the ball 10 so that the ball 10 always abuts against the outer wall of the metal frame, thereby achieving the function of fixing the position of the ball 10.
[0030] like Figure 1-5 As shown, a directional screw head 17 is fixedly connected to the outer periphery of the threaded block 15, and a bevel 11 is provided at the end of the mounting tube 8. The diameters at both ends of the sliding cavity 12 are smaller than the diameter in the middle of the sliding cavity 12. The bevel 11 facilitates the mounting tube 8 to pass through the metal frame. The diameters at both ends of the sliding cavity 12 are smaller than the diameter in the middle of the sliding cavity 12 to prevent the ball 10 from leaving the sliding cavity 12, thereby limiting the position of the ball 10.
[0031] like Figure 1-5 As shown, the support layer includes a longitudinal support frame 2 and a transverse support frame 3. The longitudinal support frame 2 and the transverse support frame 3 are evenly staggered and arranged. The multi-level staggered structure has strong support stability and strong bearing capacity.
[0032] like Figure 1-5 As shown, a sealing gasket 4 is fixedly connected to the intersection of the longitudinal support frame 2 and the transverse support frame 3, and the sealing gasket 4 is welded to the ETFE film 1. The connection with the ETFE film 1 is performed through the sealing gasket 4 to prevent damage to the ETFE film 1 during the connection, and the multi-point support has a good support effect.
[0033] like Figure 1-5As shown, the metal frame includes a main mounting metal frame 5 and a sub-mounting metal frame 6. The main mounting metal frame 5 and the sub-mounting metal frame 6 are fixedly connected. During installation, the ETFE film 1 is first installed on the support layer and then inserted into the main mounting metal frame 5. Then, the sub-mounting metal frame 6 is plugged into the other end of the support layer, and then the sub-mounting metal frame 6 is connected to the main mounting metal frame 5 to realize the function of the combined metal frame.
[0034] like Figure 1-5 As shown, the metal frame is fixedly connected with sealing strips 18 on all sides, and the direction screw head 17 abuts against the sealing strips 18, so that the sealing performance of the installation pipe 8 is improved by the sealing strips 18.

The sealant 7 improves the sealing between the metal frame, the supporting layer and the ETFE film 1.
[0036] Working principle: When installing the ETFE membrane 1, the main mounting metal frame 5 and the auxiliary mounting metal frame 6 are inserted on both sides of the support layer through the mounting tube 8, and the thread block 15 is screwed into the mounting tube 8 through the direction screw head 17 and the thread groove 14. The extrusion pin 16 matches the inner diameter of the sliding groove 13. After entering the mounting tube 8, the balls 10 on both sides can be squeezed so that the two sides of the balls 10 are stuck on the outside of the metal frame, thereby fixing the ETFE membrane 1. The ETFE membrane 1 will not be damaged during installation, and the overall sealing of the ETFE membrane structure can be improved, preventing the ETFE membrane structure from leaking after long-term use, thereby improving the sealing performance of the structure.
