Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a roof cable-stayed fixing structure. Background Technology

[0002] In modern architecture, roof structures often face the demands of large spans and high strength, especially in large public buildings such as stadiums, exhibition halls, and train stations. To achieve large-span and stable roof systems, materials and forms such as reinforced concrete, steel structures, or cable-stayed structures are typically used. In cable-stayed roof structures, the stay cables are generally connected to the hangers on the roof via forks at their ends. However, due to the axial clearance between the forks and hangers, the forks are prone to axial movement relative to the hangers, affecting the stability of the stay cables. To address this, the inventors have proposed a roof cable-stayed fixing structure. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0031] In related technologies, modern architecture often faces the challenge of large spans and high strength in roof structures, especially in large public buildings such as stadiums, exhibition halls, and train stations. To achieve large-span and stable roof systems, materials and forms such as reinforced concrete, steel structures, or cable-stayed structures are typically used. In cable-stayed roof structures, the stay cables are generally connected to the hangers on the roof via forks at their ends. However, due to the axial clearance between the forks and the hangers, the forks are prone to axial movement relative to the hangers, affecting the stability of the stay cables.

[0032] This embodiment provides a roof cable fixing structure for connecting the cable to the lugs on the roof. It can eliminate the axial gap between the lugs and the lugs, and improve the stability of the cable.

[0033] Please see Figures 1-2 In this embodiment, a roof cable fixing structure includes a fork lug 10, a positioning sleeve 20, and a pin 30; the fork lug 10 is fixed to the end of the cable 50; the positioning sleeve 20 is screwed into the connecting hole 11 of the fork lug 10; the pin 30 is inserted into the inside of the positioning sleeve 20, and a locking nut 31 that abuts against the outer end of the positioning sleeve 20 is screwed onto the pin 30; wherein, the inner end of the positioning sleeve 20 abuts against the side wall of the lug 40, and the pin 30 passes through the through hole 41 on the lug 40.

[0034] By adopting the technical solution of this embodiment, after the positioning sleeve 20 is screwed in, it abuts against the side wall of the lug 40, which can eliminate the axial gap between the fork lug 10 and the lug 40, prevent the fork lug 10 from moving axially relative to the lug 40, and improve the stability of the cable 50.

[0035] It should be noted that the lifting lug 40 is fixedly connected to the roof 60. The lifting lug 40 has a through hole 41 for connecting with the fork lug 10. The fork lug 10 is fixedly connected to the end of the inclined cable 50. The fork lug 10 is constructed in a U-shape and has two parallel legs. The legs have a connecting hole 11 for connecting the positioning sleeve 20 and the pin 30. The positioning sleeve 20 passes through the connecting hole 11 and forms a threaded connection with the connecting hole 11. The pin 30 passes through the positioning sleeve 20 and passes through the lifting lug 40 through the through hole 41. Locking nuts 31 are threaded at both ends of the pin 30, thereby connecting the fork lug 10 to the lifting lug 40.

[0036] It should be understood that because the distance between the two legs of the fork lug 10 is greater than the thickness of the lug 40, there is a gap between the two legs of the fork lug 10 and the lug 40. The existence of this gap will cause the fork lug 10 to move axially relative to the lug 40. The axial movement mentioned here refers to the movement along the axis of the pin 30. In this embodiment, a positioning sleeve 20 is added. By screwing the positioning sleeve 20 toward the lug 40 until the inner end of the positioning sleeve 20 abuts against the outer wall of the lug 40, the distance between the effective clamping surfaces of the two legs of the fork lug 10 can be adjusted by the movement of the positioning sleeve 40, thereby avoiding the existence of the aforementioned gap and ensuring the stability of the cable 50.

[0037] In this embodiment, the connecting holes 11 are coaxially arranged on the two legs of the fork lug 10, and the two connecting holes 11 are symmetrically arranged. The positioning sleeve 20 is screwed into the inside of the connecting hole 11, and the two positioning sleeves 20 are symmetrically arranged on the fork lug 10. An abutment ring 21 is integrally formed at the inner end of the positioning sleeve 20, and the abutment ring 21 is coaxially arranged with the positioning sleeve 20. The abutment ring 21 is flush with the inner end face of the positioning sleeve 20. The outer diameter of the abutment ring 21 is larger than the outer diameter of the positioning sleeve 20, and the inner diameter of the abutment ring 21 is equal to the outer diameter of the positioning sleeve 20. After the positioning sleeve 20 is screwed toward the lifting lug 40, the abutment surface 21 abuts against the side wall of the lifting lug 40. The two positioning sleeves 20 clamp the lifting lug 40 from both sides.

[0038] In this embodiment, the pin 30 is inserted entirely inside the positioning sleeve 20, and the outer diameter of the pin 30 is equal to the diameter of the through hole 41 on the lifting lug 40. At the same time, the outer diameter of the pin 30 is also equal to the inner diameter of the positioning sleeve 20. The pin 30 passes through the lifting lug 40 and the two legs of the fork lug 10. The locking nut 31 is screwed onto both ends of the pin 30, and the locking nut 31 abuts against the outer end face of the corresponding positioning sleeve 20. The two locking nuts 31 lock the pin 30 onto the lifting lug 40 and the fork lug 10, thereby realizing the connection between the fork lug 10 and the lifting lug 40.

[0039] To facilitate the rotation of the positioning sleeve 20, the outer diameter of the locking nut 31 can be set to be smaller than the outer diameter of the positioning sleeve 20.

[0040] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
