[0043] As a preferred embodiment, the first cable clamp structure 2 includes: a base plate 21 , a cable sleeve 22 , a first clamping plate 23 , and a cover plate 24 .

[0044] The base plate 21 is installed on the cantilever beam 1. The circumferential cable 6 is movably inserted into the cable sleeve 22.

[0045] The cable sleeve 22 is movably disposed above the base plate 21. A notch is formed on one side of the cable sleeve 22.

[0046] Two first clamping plates 23 are positioned opposite each other. They clamp onto the cable loop 22. A locking member 231 is formed on the inner side of one first clamping plate 23. The locking member 231 is inserted into the notch and presses against the circumferential cable 6. A slot is formed on the outer side of the other first clamping plate 23. A first anchor 25 is connected between the two first clamping plates 23.

[0047] In this embodiment, the first anchoring member includes a tensioning screw and a screw-fitting member. The first clamping plates are provided with horizontal through-holes. The tensioning screw is inserted into the horizontal through-holes of the two first clamping plates. The screw-fitting member is screwed onto both ends of the tensioning screw and presses against the outer sides of the two first clamping plates.

[0048] As a preferred embodiment, the cable sleeve is provided with a horizontal through-hole, which is coaxial with the horizontal through-hole of the first clamping plate, and the tension screw is also passed through the horizontal through-hole of the cable sleeve.

[0049] The cover plate 24 is mounted on the two first clamping plates 23. The first clamping plates 23 are provided with vertical through-holes. A second anchor 26 is inserted through the vertical through-holes. The second anchor 26 is secured to the base plate 21 and the cover plate 24. The second cable clamp structure 3 is mounted on the cover plate 24. The base plate and cover plate are respectively clamped to the two first clamping plates and the cable loop by the second anchor.

[0050] In this embodiment, the structure of the second anchor is identical to that of the first. The cover plate and base plate each have a vertical through-hole. The vertical through-holes in the base plate, cover plate, and first clamping plate are coaxially arranged. The screw of the second anchor is inserted through the vertical through-holes in the base plate, cover plate, and first clamping plate. The screwed members of the second anchor press against opposing sides of the cover plate and base plate, respectively.

[0051] See Figure 1 As shown, two limiting plates 27 are installed on the outer side of the other first clamping plate 23 , and a clamping groove is formed between the two limiting plates and the outer side of the other first clamping plate 23 .

[0052] In this embodiment, the second cable clamp structure 3 includes a supporting column 31 and a second clamping plate 32 .

[0053] The support column 31 is mounted on the cover plate 24. There are two second clamping plates 32. One second clamping plate 32 is fixed to the upper end of the support column 31. Opposite sides of the two second clamping plates 32 each have a receiving slot. A third anchor 33 is connected between the two second clamping plates 32. The receiving slots of the two second clamping plates 32 enclose a locking hole. The radial cable 7 is inserted into the locking hole.

[0054] As a preferred embodiment, the cover plate 24 is formed with a plug connector. The lower end of the support column 31 is provided with a socket hole. The plug connector is inserted into the socket hole.

[0055] The present invention provides a construction method for a transition structure between an ETFE roofing membrane cable and a cornice, comprising the following steps:

[0056] S1. Connect multiple cantilever beams 1 to the eaves structure so that the multiple cantilever beams 1 are arranged at intervals along the circumference of the eaves structure.

[0057] S2. Clamp the first cable clamp structure 2 to the annular cable 6 of the ETFE roofing membrane cable, and install the first cable clamp structure 2 on the second end of the cantilever beam 1.

[0058] S3. Expand the membrane 8 of the ETFE roofing membrane cable above the main roofing cable, and insert the radial cable 7 of the ETFE roofing membrane cable into the membrane attachment sleeve 81 of the membrane.

[0059] S4. Clamp the second cable clamp structure 3 to the radial cable 7 of the ETFE roofing membrane cable, and detachably install the second cable clamp structure 3 on the first cable clamp structure 2.

[0060] S5. Embed the end of the radial cable 7 in the arc-shaped groove of the cable saddle 5 and detachably connect it to the anchor plate 4.

[0061] S6. Tension radial cable 7 to the designed tension force.

[0062] After the main cables of the ETFE roofing membrane cable structure are installed, the hoop cables and cantilever beams are installed first. The cable saddles and anchor plates on the cantilever beams are securely welded together before being installed on the work surface. Once the cantilever beams are installed, the end plates are secured. The baseplate is then installed on the cantilever beams. During installation, the baseplate is welded to the cantilever beams, and then the cable sleeves are installed, securing them around the hoop cables. The first clamping plate, cover plate, and stopper plate are then installed in sequence, each secured with anchors to form the first cable clamp structure.

[0063] Then install the support column so that it is sleeved on the reserved plug connector on the cover plate, and then tighten the connecting bolts of the support column to lock the plug connector.

[0064] Unfold the membrane over the main roof cables, threading the radial cables through the membrane sleeves as the membrane is unfolded. The radial cables are then threaded through the keyholes and cable saddles of the second plywood. The second plywood is then mounted on the support column and the third anchor is tightened. Next, insert the end connector of the radial cable into the anchor plate and secure it with the radial cable end pin. The radial cable is then tensioned to the designed tension, completing the installation process.

[0065] The present invention's transition structure for connecting ETFE roofing membrane cables to cornices utilizes components such as cable saddles, anchor plates, and base plates to reliably connect the radial and circumferential cables of the ETFE roofing membrane cable structure to the cantilever beams. This provides a stable transition connection between the roofing cable support structure and the cornice, while ensuring connection strength. Each component of the present invention's transition structure for connecting ETFE roofing membrane cables to cornices can be modularized and standardized, facilitating installation and subsequent maintenance.
