[0051] To make the objectives, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings. Apparently, the described embodiments are some but not all of the embodiments of the utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.
[0052] Embodiment 1
[0053] As Figures 1-6As shown in the figure, this embodiment proposes a safety railing for the up-and-down passage of a button-connected scaffolding. The safety railing is arranged above the up-and-down passage of the scaffolding. The safety railing includes vertical poles 2, which are vertically arranged and connected between the upper and lower layers of scaffolding crossbars. In this embodiment, the height of the vertical poles 2 is 2m, which is the same as the working layer height of the scaffolding.
[0054] Both the upper and lower ends of the vertical poles 2 are connected with snap rings, and the snap rings are used to connect with the scaffolding crossbars.
[0055] The snap ring includes a fixed half-ring 3 and a movable half-ring 4. One end of the fixed half-ring 3 is fixedly connected to the vertical pole 2, and the movable half-ring 4 is movably connected to the fixed half-ring 3, and the two can be locked by fasteners. The movable half-ring 4 and the fixed half-ring 3 form a bayonet for clamping on the scaffolding crossbar.
[0056] The movable half-ring 4 and the fixed half-ring 3 adopt metal snap rings, such as iron snap rings. The fixed half-ring 3 is welded to the end of the vertical pole 2, and the movable half-ring 4 is movable.
[0057] In this embodiment, the movable half-ring 4 is slidably connected to the fixed half-ring 3. The movable half-ring 4 slides relative to the fixed half-ring 3, which can change the size of the bayonet and realize the opening and closing of the snap ring. When in use, the snap ring is clamped on the scaffolding crossbar. Specifically, the scaffolding crossbar is inserted into the fixed half-ring 3, and then the movable half-ring 4 is slid to surround the scaffolding crossbar. Finally, the movable half-ring 4 and the fixed half-ring 3 are locked by the fasteners to realize the connection between the vertical pole 2 and the scaffolding crossbar.
[0058] Furthermore, arc-shaped card slots 6 are opened on both the fixed half-ring 3 and the movable half-ring 4, and the arc-shaped card slots 6 are opened in the middle of the fixed half-ring 3 and the movable half-ring 4.
[0059] One end of the fixed half-ring 3 is fixedly connected to the vertical pole 2, and a first bolt 7 is arranged at the other end of the fixed half-ring 3. A second bolt 8 is arranged at the end of the movable half-ring 4 connected to the fixed half-ring 3. The first bolt 7 is located in the arc-shaped card slot 6 on the movable half-ring 4, and the second bolt 8 is located in the arc-shaped card slot 6 on the fixed half-ring 3. Among them, the first bolt 7 is welded on the fixed half-ring 3, and the second bolt 8 is welded on the movable half-ring 4.
[0060] When the movable semi-ring 4 slides relative to the fixed semi-ring 3, the second bolt 8 slides along the arc-shaped card slot 6 on the fixed semi-ring 3. At the same time, the first bolt 7 slides along the arc-shaped card slot 6 on the movable semi-ring 4. When the first bolt 7 and the second bolt 8 are closest to each other, the end of the movable semi-ring 4 is connected to the end of the fixed semi-ring 3, and the snap ring is in a locked state. When the first bolt 7 and the second bolt 8 are farthest from each other, the movable semi-ring 4 almost coincides with the fixed semi-ring 3, and the snap ring is in an open state. After the movable semi-ring 4 slides in place, a fastener is connected to the first bolt 7 and the second bolt 8, and the fastener is tightened to relatively fix the movable semi-ring 4 and the fixed semi-ring 3.
[0061] The fastener preferably adopts a dovetail nut 5. The dovetail nut 5 includes a nut body, and convex rods are arranged on both sides of the nut body for easy hand-held rotation of the nut. When the dovetail nut 5 is tightened, the movable semi-ring 4 is tightly connected to the fixed semi-ring 3. When the dovetail nut 5 is loosened, the movable semi-ring 4 can slide relative to the fixed semi-ring 3.
[0062] The sliding connection between the movable semi-ring 4 and the fixed semi-ring 3 is not limited to the above method. It can also adopt a method of only opening an arc-shaped card slot 6 on the fixed semi-ring 3, arranging a sliding block or a sliding column on the movable semi-ring 4, and slidingly connecting the sliding block or the sliding column in the arc-shaped card slot 6, which can also realize the relative sliding of the movable semi-ring 4 and the fixed semi-ring 3 and the opening and closing of the snap ring.
[0063] The connection between the movable semi-ring 4 and the fixed semi-ring 3 is not limited to the above sliding connection. It can also adopt a method of rotatably connecting one end of the movable semi-ring 4 to the end of the fixed semi-ring 3, and changing the size of the bayonet by rotating the movable semi-ring 4 to realize the opening and closing of the snap ring. During use, the scaffold crossbar is inserted into the fixed semi-ring 3, then the movable semi-ring 4 is rotated to surround the scaffold crossbar, and finally the movable semi-ring 4 and the fixed semi-ring 3 are tightly locked by the fastener to realize the connection between the vertical pole 2 and the scaffold crossbar.
[0064] A plurality of the vertical poles 2 are arranged at certain intervals above the upper and lower passages of the scaffold, which can realize the protection of the free surface above the upper and lower passages of the scaffold, solve the problem that there is a free surface directly above the steel ladder (upper and lower passage) after the steel ladder is installed on the scaffold, and there is a risk of falling when the operator works on the operation layer above the steel ladder, and improve the construction safety.
[0065] The protective railing of the present utility model is reliably connected to the disc buckle type scaffold, has a good protective effect, and ensures the operation safety of the operator.

[0069] A disc 1 is also installed on the scaffolding vertical pole. The disc 1 on the vertical pole 2 has the same structure as the disc 1 on the scaffolding vertical pole and their positions correspond. The disc 1 is welded to the vertical pole 2 and the scaffolding vertical pole.
[0070] Multiple connection holes are provided on the disc 1. A cross bar is arranged between the vertical pole 2 and the adjacent scaffolding vertical pole. Both ends of the cross bar are connected with fasteners, and the fasteners are connected to the disc 1. The fastener includes a clamp and a pin. One end of the clamp is fixedly connected to the end of the cross bar. The other end of the clamp has a slot, and the disc 1 is stuck in the slot. The pin is vertically inserted into the clamp and the connection hole.
[0071] The connection of the cross bar to the scaffolding is beneficial to realizing the reliable connection between the protective railing and the scaffolding and improving the stability of the protective railing.
[0072] When multiple vertical poles 2 are arranged, a cross bar can also be arranged between two adjacent vertical poles 2 to further improve the protection effect.
[0073] The existing socket - and - spigot steel pipes can be directly used for the cross bar, which is beneficial to cost saving.
[0074] The vertical pole 2 and the cross bar jointly form a fence to protect the free - face above the upper and lower passages of the scaffolding, preventing operators from falling from the free - face when working on the working layer above the upper and lower passages of the steel - ladder scaffolding, improving the construction safety. The reliable connection between the vertical pole 2, the cross bar and the scaffolding is beneficial to improving the protection effect.
[0075] During installation, first install the vertical pole 2 on the socket - and - spigot scaffolding. Loosen the dovetail nuts 5 at both ends of the vertical pole 2, clamp the snap rings at both ends of the vertical pole 2 on the scaffolding cross bar, slide the movable half - ring 4 to hold the scaffolding cross bar, and then lock the dovetail nuts 5 to complete the installation of the vertical pole 2. Then fix the cross bar on the vertical pole 2 and the scaffolding, and connect the fasteners at both ends of the cross bar to the discs 1 on the vertical pole 2 and the scaffolding vertical pole. If multiple vertical poles 2 are arranged, the cross bar can also be arranged between the vertical poles 2.
