It can be understood that the specific embodiments described herein are merely for explaining the relevant invention and not for limiting the invention. Additionally, it should be noted that for the sake of convenience of description, only the parts related to the invention are shown in the drawings.

[0034] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will detail the present application with reference to the drawings and in conjunction with the embodiments.

[0035] Refer to Figures 1 to 6 As shown, the present invention provides a slip - type safety flat net protection device for grid bulk installation, including a suspended pipe section 1, a slide rail 2, and a safety net 3.

[0036] The number of suspended pipe sections 1 is multiple. In this embodiment, the grid is arched. As Figure 1 shown is the structure on one side in the arc - forming direction of the grid. Specifically, a suspended pipe section 1 is detachably suspended on a bolt ball 42 on the lower chord rod 41 of the grid. The suspended pipe sections 1 on a row of bolt balls 42 on the lower chord rod 41 are coaxially arranged. A passage gap is provided on the lower side wall of the suspended pipe section 1.

[0037] The sliding rail 2 is slidably disposed in at least two adjacent suspended pipe sections 1. A hanging plate 21 is formed at the bottom of the sliding rail 2. The hanging plate 21 is slidably disposed in the passage gap. The sliding rail 2 is arranged in the horizontal direction. The hanging plate 21 is perpendicular to the sliding rail 2. The sliding rail 2 and the hanging rod are in a T shape.

[0038] The lower part of the hanging plate 21 extends below the passage gap. The safety net 3 is connected to the hanging plates 21 on at least two adjacent rows of bolt balls 42.

[0039] The sliding safety flat net protection device for grid bulk installation of the present invention is used to solve the protection problem of high-altitude bulk installation of a curved arch bolt ball 42 grid. Specifically, it is arranged below the installed curved grid structure, can complete the horizontal sliding of the safety flat net in the direction perpendicular to the arch section, can follow the construction progress and construction area, achieve all-round protection, reduce the difficulty of grid protection tensioning, and improve the installation efficiency of the grid protection device.

[0040] As a preferred embodiment, the suspended pipe section 1 is a square pipe. The square pipe is arranged in the same direction as the lower chord rod 41. A passage gap is formed in the lower side wall of the square pipe.

[0041] Two rows of support rollers 11 are installed on the inner side of the lower side wall of the suspended pipe section 1. The two rows of support rollers 11 are respectively arranged on the opposite two layers of the passage gap. The support roller 11 supports the sliding rail 2.

[0042] In this embodiment, a limit roller 12 is installed on the inner side of the upper side wall of the suspended pipe section 1. The limit roller 12 presses against the upper part of the sliding rail 2.

[0043] As a preferred embodiment, the number of the limit rollers 12 is two rows. The two rows of limit rollers 12 are respectively arranged on the opposite sides of the sliding rail 2. In this embodiment, the positions of the limit rollers 12 and the support rollers 11 correspond to each other, and the sliding rail 2 is slidably disposed between the limit roller 12 and the support roller 11.

[0044] In this embodiment, a screw 22 is screwed into the threaded hole of the bolt ball 42. The lower end of the screw 22 is installed on the outer side of the upper side wall of the suspended pipe section 1.

[0045] As a preferred embodiment, a base plate 23 is connected to the lower end of the screw 22. Two first ear plates 24 arranged oppositely are vertically provided at the bottom of the base plate 23. A second ear plate 25 is connected to the outer side of the upper side wall of the suspended pipe section 1. The second ear plate 25 is movably disposed between the two first ear plates 24. A locking member 26 for locking the second ear plate 25 is installed on the first ear plate 24.

[0046] In this embodiment, a first through hole is formed in the first ear plate 24, and a second through hole is formed in the second ear plate 25. The locking member 26 is detachably inserted through the first through holes of the two first ear plates 24 and the second through hole of the second ear plate 25.

[0047] Preferably, the locking member 26 is a bolt, and nuts are screwed on both ends of the bolt. The nuts abut against the outer side of the first ear plate 24 to prevent the locking member 26 from slipping off.

[0048] As a preferred embodiment, anti-disengagement members 27 for preventing the slide rail 2 from disengaging from the suspended pipe section 1 are detachably installed at both ends of the slide rail 2 respectively.

[0049] In this embodiment, the anti-disengagement member 27 is a snap ring. The snap ring is rectangular. The length of the snap ring is greater than the outer diameter of the suspended pipe section 1. The hanging plate 21 is provided with a through hole. The through hole is arranged at the end of the hanging rod. The through hole is in an inverted L shape. The through hole has a vertical section and a horizontal section. One end of the horizontal section is connected to the upper end of the vertical section. The distance from the other end of the horizontal section to the end face of the slide rail 2 is less than the length of the snap ring. The distance from the horizontal section to the slide rail 2 is less than the width of the snap ring. The snap ring is sleeved on the slide rail 2, and the lower part of the snap ring slides in the vertical section. At this time, the snap ring is arranged along the width direction of the slide block.

[0050] When the slide rail 2 needs to be moved, the lower part of the snap ring is slid into the horizontal section, and then the snap ring is flipped so that the snap ring is arranged along the length direction of the slide rail 2. Since the width of the snap ring is less than the inner diameter of the suspended pipe section 1, the snap ring does not affect the movement of the slide rail 2 at this time. After the slide rail 2 is moved in place, the snap ring is reset (that is, the snap ring is arranged along the width direction of the slide block).

[0051] The present invention provides a construction method for a slip-type safety flat net protection device for bulk grid erection, including the following steps:

[0052] S1. A suspended pipe section 1 is detachably suspended on the bolt ball 42 on the lower chord rod 41 of the grid, so that the suspended pipe sections 1 on a row of bolt balls 42 on the lower chord rod 41 are coaxially arranged.

[0053] S2. The slide rail 2 is slid in at least two adjacent suspended pipe sections 1 on the lower chord rod 41, and the hanging plate 21 of the slide rail 2 slides in the passage gap, so that the lower part of the hanging plate 21 extends below the passage gap.

[0054] S3. The safety net 3 is connected to the hanging plates 21 on at least two adjacent rows of bolt balls 42.

[0055] After the safety net 3 is connected to the hanging plate 21, the snap ring is arranged along the width direction of the slide rail 2.

[0056] S4. After the high-altitude caulking construction at the current construction position is completed, push the slide rail 2 into at least two adjacent suspended pipe sections 1 at the next construction position, so that the safety net 3 slides to the lower part of the next construction position.

[0057] Before sliding the slide rail 2, arrange the snap ring along the length direction of the slide rail 2. Then, push the slide rail 2 to the next construction position and lock it with the snap ring.

[0058] The sliding safety flat net protection device for bulk erection of grid structures of the present invention is applicable to large-span plane grid (latticed shell) structures and single-curved grid (latticed shell) structures, and is also applicable to orientable large-span truss structures.
