Description

Technical Field

[0001] This utility model relates to the technical field of building construction, specifically to an external scaffolding flap protection device and external scaffolding. Background Technology

[0002] During construction, external scaffolding is usually erected around the building. To ensure the requirements of construction operations, there is a gap of about 300mm between the external scaffolding and the main building. Traditional protective measures use horizontal safety nets to close the gap. However, safety nets are easily damaged, and workers, building materials, tools, and construction debris are still at risk of falling, causing safety accidents. Utility Model Content

[0003] This utility model addresses one or more technical problems existing in the prior art by providing an external scaffold flap protection device and an external scaffold.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This utility model provides a protective device for flip-up scaffolding, including a protective plate, a fixed clamp, a movable clamp, and connecting bolts. The fixed clamp and the movable clamp are both arc-shaped structures. The protective plate includes a connecting edge and an abutting edge arranged opposite to each other. The outer protruding position of the fixed clamp is fixed to one side of the protective plate near the connecting edge. The two ends of the fixed clamp and the two ends of the movable clamp are detachably connected by connecting bolts to form a rod limiting channel. The abutting edge of the protective plate is bent towards one side to form an arc-shaped abutting edge.

[0005] The beneficial effects of this utility model are as follows: The external scaffolding flip-up protective device of this utility model, through its flip-up design, can effectively seal the gap between the scaffolding and the building's exterior wall, preventing personnel, materials, or tools from falling. It can also flexibly switch between protective and operational states according to construction needs, eliminating the need for repeated disassembly and assembly, significantly improving construction safety and operational convenience. By setting the abutment edge of the protective plate to an arc-shaped abutment edge, the sharp end of the protective plate is prevented from abutting against the exterior wall, which could pose a risk of embedding into the wall and making it difficult to flip back into place. By setting fixed clamps and movable clamps, with the fixed clamps fixed to the protective plate and the movable clamps set independently, the fixed clamps and the protective plate can form a whole, facilitating assembly and positioning.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the outer arc surface of the arc-shaped abutment edge is provided with an elastic pad.

[0008] The beneficial effect of adopting the above-mentioned further solution is that by setting up elastic pads, impact absorption can be achieved when the protective panel comes into contact with the exterior wall surface.

[0009] Furthermore, the protective plate is provided with at least two fixing clamps, which are arranged side by side along the connecting edge, and the protective plate is fixed with a fixing clamp at each end of the connecting edge.

[0010] The beneficial effects of adopting the above-mentioned further solution are: by setting at least two fixing clamps and fixing one fixing clamp at each end of the connection edge, the installation structure of the protective plate is more stable and reliable, and the force is evenly distributed.

[0011] Furthermore, the central axis of the rod limiting channel is arranged parallel to both the connecting edge and the abutting edge.

[0012] Furthermore, the protective plate is fixed at the center of the outer protrusion of the fixing clamp.

[0013] The advantage of adopting the above-mentioned further solution is that it avoids interference with the bolts when the protective plate is connected to the fixing clamp.

[0014] Furthermore, the protective plate is welded and fixed to the fixing clamp or fixed to the fixing clamp by bolts.

[0015] Furthermore, an auxiliary handle is provided on one side of the protective plate. The auxiliary handle has a U-shaped structure, and the two ends of the U-shaped structure are respectively fixed to one side of the protective plate.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by setting an auxiliary handle, it is convenient to manually flip the protective plate during use.

[0017] Furthermore, the protective plate has a rectangular structure, and both the inner side of the fixed clamp and the inner side of the movable clamp are provided with elastic pads.

[0018] This utility model also provides an external scaffold, including the aforementioned external scaffold flip-up protective device, and a scaffold body. The scaffold body is installed at intervals on one side of the building's exterior wall. The longitudinal horizontal bars of the scaffold body are arranged close to the building's exterior wall. The fixed clamps and movable clamps are fastened to the outside of the longitudinal horizontal bars, allowing the longitudinal horizontal bars to be movably fitted within the bar's limiting channel. The protective plate can be flipped around the longitudinal horizontal bars and allow the outer arc surface of the arc-shaped abutment edge to abut against the surface of the building's exterior wall, or flipped around the longitudinal horizontal bars to a vertical state.

[0019] The beneficial effects of this utility model are: the protective device of this utility model can be flipped and abutted against the outer wall when in use, and can be flipped to a vertical position when not in use to act as a protective railing for personnel. It can effectively seal the gap between the scaffolding and the building to prevent personnel, materials or tools from falling, and can flexibly switch between the protective state and the working state according to the construction needs without repeated disassembly and assembly, which significantly improves construction safety and operation convenience.

[0020] Furthermore, one side of the protective plate is provided with a hanging support rod, one end of which is movably connected to one side of the protective plate. A hook is provided on the scaffold board on one side of the longitudinal horizontal bar. When the protective plate is rotated around the longitudinal horizontal bar to a vertical state, the other end of the hanging support rod can be hooked onto the hook.

[0021] The beneficial effect of adopting the above-mentioned further solution is that by setting up hanging support rods, the protective plate can be effectively supported, avoiding excessive rotation angle of the protective plate, which would affect the normal operation of construction workers on the scaffold.

[0032] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0033] Example 1

[0034] like Figures 1-5 As shown, an external scaffolding flap protection device of this embodiment includes a protective plate 1, a fixed clamp 2, a movable clamp 3, and connecting bolts 4. The fixed clamp 2 and the movable clamp 3 are both arc-shaped structures. The protective plate 1 includes a connecting edge 11 and an abutting edge arranged opposite to each other. The outer protruding position of the fixed clamp 2 is fixed to one side of the protective plate 1 near the connecting edge 11. The two ends of the fixed clamp 2 and the two ends of the movable clamp 3 are detachably connected by the connecting bolts 4 to form a pole limiting channel. The abutting edge of the protective plate 1 is bent toward one side to form an arc-shaped abutting edge 12.

[0035] like Figure 3 As shown, in a preferred embodiment, the outer arc surface of the arc-shaped abutment edge 12 is provided with an elastic pad 13. The elastic pad 13 can be a rubber buffer strip (hardness 70±5, Shore A) or can be bonded to the steel plate with VHB double-sided tape (bonding strength ≥1.2MPa) for absorbing impact when in contact with the building wall.

[0036] Furthermore, such as Figure 3 As shown, the central axis of the rod limiting channel is arranged parallel to the connecting edge 11 and the abutting edge, respectively.

[0037] Optional, such as Figure 3 As shown, the protective plate 1 is fixed at the center of the outer protrusion of the fixing clamp 2. This prevents interference with the bolts when the protective plate is connected to the fixing clamp.

[0038] like Figure 3 As shown, in this embodiment, the protective plate 1 is welded and fixed to the fixing clamp 2 or fixed to the fixing clamp 2 by bolts. Specifically, the fixing clamp 2 can be permanently fixed to the protective plate 1 by a continuous fillet weld (weld leg height 4mm). The fixed connection strength between the protective plate 1 and the fixing clamp 2 is sufficient to support the standing strength of the construction personnel.

[0039] In this embodiment, the fixed clamp 2 and the movable clamp 3 can be connected to the fixed component by M8×25 stainless steel bolts to form a detachable rotating pair.

[0040] like Figure 1 and Figure 4 As shown, in a preferred embodiment, the protective plate 1 is a rectangular structure, and elastic pads are provided on the inner side of both the fixed clamp 2 and the movable clamp 3.

[0041] Preferably, the protective plate 1 in this embodiment has reinforced flange structures on both sides, which is beneficial to the stability of the overall structure. Both the fixed clamp 2 and the movable clamp 3 in this embodiment are Ω-shaped and are made of Q345 metal.

[0042] In this embodiment, the external scaffolding flap protection device, in its protective state, allows the protective panel to unfold naturally against the wall, with its elastic pads at the ends maintaining elastic contact with the building's exterior wall, forming a continuous, closed protective surface. When switching to the working mode, the operator can apply a tangential force to the auxiliary handle, causing the protective panel to rotate around the longitudinal horizontal bar to a vertical position. During this conversion, while ensuring a reliable connection between the protective panel and the longitudinal horizontal bar, controllable rotational freedom of the protection device can be achieved. After the mode conversion is completed, the protective panel can be temporarily fixed to provide the necessary space for construction operations.

[0043] The external scaffolding flap protection device in this embodiment adopts a standardized and modular design concept. The standard size of a single protective plate is 300mm (±2mm) width × 450mm (±3mm) length × 2mm thickness (Q235B cold-rolled steel plate). Through the linear combination of multiple protective plates, it can adapt to the installation requirements of different scaffolding upright spacing within the range of 400~1500mm, and meet the engineering application scenarios of various building facade contour changes.

[0044] The modular design of the external scaffolding flap protection device in this embodiment provides excellent adaptability. Each protective panel uses a uniform specification of 300mm width × 450mm length, allowing for flexible combination and installation based on the actual spacing of scaffolding uprights in different projects, effectively solving protection challenges caused by changes in the building's outer contour. Secondly, the rotating pipe clamp structure (fixed and movable clamps) allows workers to easily and quickly switch between protection and work modes, significantly improving construction efficiency. In terms of structural reliability, the rotating pipe clamp structure forms a stable connection with the longitudinal horizontal bars of the scaffolding, and together with the steel plate protective panels, it can withstand various load impacts during construction. Furthermore, the modular nature of this device brings significant economic advantages. All components can be easily disassembled and reused, reducing material waste and the labor costs associated with frequent replacements of traditional safety nets, achieving a dual improvement in safety protection and economic benefits. These combined advantages make this technical solution of significant value for widespread application in the field of safety protection for high-rise building construction.

[0045] The scaffolding flip-up protective device in this embodiment, through its flip-up design, effectively seals the gap between the scaffolding and the building's exterior wall, preventing personnel, materials, or tools from falling. It also allows for flexible switching between protective and operational states according to construction needs, eliminating the need for repeated disassembly and reassembly, significantly improving construction safety and operational convenience. By setting the abutment edge of the protective plate to an arc shape, the sharp point of the protective plate is prevented from abutting against the exterior wall, which could pose a risk of embedding and make it difficult to flip back into place. By setting fixed and movable clamps, with the fixed clamps fixed to the protective plate and the movable clamps set independently, the fixed clamps and the protective plate can form a unified whole, facilitating assembly and positioning.

[0046] Example 2

[0047] Based on Embodiment 1, this embodiment provides a preferred configuration for the fixing clamp 2. For example... Figure 1 and Figure 4 As shown, the protective plate 1 is provided with at least two fixing clamps 2, which are arranged side by side along the connecting edge 11. One fixing clamp 2 is fixed to each end of the connecting edge 11. By providing at least two fixing clamps and fixing one to each end of the connecting edge, the installation structure of the protective plate is made more stable and reliable, and the stress is distributed evenly.

[0048] Example 3

[0049] Based on Embodiment 1 or Embodiment 2, this embodiment also provides a preferred embodiment of the protective plate 1. For example... Figure 1 and Figure 3 As shown, an auxiliary handle 14 is also provided on one side of the protective plate 1. The auxiliary handle 14 has a U-shaped structure, and the two ends of the U-shaped structure are respectively fixed to one side of the protective plate 1. By providing an auxiliary handle, it is convenient to manually flip the protective plate during use.

[0050] Example 4

[0051] This embodiment also provides an external scaffold, including an external scaffold flip-up protective device according to any of the above embodiments, and also includes a scaffold body 5. The scaffold body 5 is installed at intervals on one side of the building exterior wall 6. The longitudinal horizontal bar 51 of the scaffold body 5 is arranged close to the building exterior wall 6. The fixed clamp 2 and the movable clamp 3 are fastened to the outside of the longitudinal horizontal bar 51, so that the longitudinal horizontal bar 51 is movably sleeved in the bar body limiting channel. The protective plate 1 can be flipped around the longitudinal horizontal bar 51 and the outer arc surface of the arc-shaped abutment edge 12 abuts against the surface of the building exterior wall 6 or flipped around the longitudinal horizontal bar 51 to a vertical state.

[0052] In this embodiment, the longitudinal horizontal bar 51 is the main horizontal bar of the scaffold body 5. The external scaffold flip-up protective device is installed on the inside of the scaffold body to effectively seal the construction gap between the scaffold body and the main structure of the building's exterior wall, preventing personnel and materials from falling.

[0053] In this embodiment, when the external scaffolding flip-up protective device flips and abuts against the building's exterior wall, the protective plate 1 can be located either below or above the fixed clamp 2. Preferably, the protective plate 1 is located below the fixed clamp 2, which facilitates the installation of the connecting bolts 4 from above when installing the protective plate 1, so that the fixed clamp 2 and the movable clamp 3 are connected and fixed.

[0054] The external scaffolding flip-up protective device in this embodiment has two working states: (1) In the protective state, multiple protective plates on the same longitudinal horizontal bar unfold to form a continuous protective surface. One side is fixed to the longitudinal horizontal bar of the scaffolding (Φ48×3.5mm steel pipe) by a pipe clamp assembly (fixed clamp and movable clamp), and the other side maintains 10~15mm elastic contact with the building's exterior wall to achieve full-enclosed protection; (2) In the construction state, the operator can use an auxiliary handle to apply a torque of no more than 8N·m to make the protective plate smoothly flip around the longitudinal horizontal bar to a vertical position, and then temporarily fix it, providing a working space of up to 300mm in width, which is convenient for workers to perform operations such as template installation, masonry or plastering. The vertically arranged protective plates can also play a temporary protective role. After the construction is completed, the protective plate can be pushed lightly and automatically reset to the protective state under its own weight. The whole process does not require the use of tools and is simple and quick to operate.

[0055] In this embodiment, the protective device on the external scaffolding can be flipped up and abutted against the external wall when in use, and can be flipped up to a vertical position when not in use to act as a safety railing for personnel. It can effectively seal the gap between the scaffolding and the building to prevent personnel, materials or tools from falling, and can flexibly switch between the protective state and the working state according to the construction needs without repeated disassembly and assembly, which significantly improves construction safety and operation convenience.

[0056] Example 5

[0057] Based on Embodiment 4, this embodiment provides a support scheme for the protective plate 1 to be in a vertical state. For example... Figure 5As shown, one side of the protective plate 1 is provided with a hanging support rod 53. One end of the hanging support rod 53 is movably connected to one side of the protective plate 1. A hook is provided on the scaffold board 52 on one side of the longitudinal horizontal bar 51. When the protective plate 1 is rotated around the longitudinal horizontal bar 51 to a vertical state, the other end of the hanging support rod 53 can be hooked onto the hook. By setting the hanging support rod, the protective plate can be effectively supported, avoiding excessive rotation angle of the protective plate, which would affect the normal operation of construction workers on the scaffold board.
