Description

Technical Field

[0001] The utility model relates to the technical field of construction protection, in particular to a turnover safety protection device capable of self-adapting and adjusting in a stairwell. Background Art

[0002] During construction, temporary safety railings are usually installed along the edges of staircases to ensure the safety of construction workers. These temporary railings are typically made of welded steel pipes or steel bars. When the permanent staircase is installed, these temporary railings need to be removed. However, due to the welded connection method, disassembly is very difficult. Moreover, the specifications of staircases vary from building to building, making it difficult to reuse these temporary safety railings.

[0003] The Chinese utility model patent application disclosed in CN112324173A is a temporary safety protection device for stair installation based on construction. Although the utility model has good effects, it cannot be adjusted according to the required lengths and angles of different stair sections during use. In addition, the protective assembly and disassembly work volume is large, the turnover efficiency is low, and it cannot be effectively used in aluminum alloy formwork systems. Utility Model Content

[0004] The purpose of the utility model is to provide a turnover safety protection device which can be adaptively adjusted in a stairwell, so as to solve the problem of low turnover efficiency of the existing temporary safety protection devices installed on the stairs.

[0005] This utility model provides a reusable safety protection device for stairwells that can be adaptively adjusted. It includes two vertical protective posts, telescopic tube assemblies located at the middle and top of the two vertical protective posts, and multiple fixing plates. Each telescopic tube assembly includes a fixed-end horizontal tube and a movable-end horizontal tube. Each vertical protective post has a pin at its lower end. The outer sides of both the fixed-end and movable-end horizontal tubes are rotatably connected to the corresponding vertical protective post. The upper side of each vertical protective post has multiple first bolt holes spaced apart. The outer sides of both the fixed-end and movable-end horizontal tubes have multiple second bolt holes. The ends of both the fixed-end and movable-end horizontal tubes are connected to the corresponding vertical protective post via a fixing plate. The two ends of each fixing plate are fixed to adjacent first and second bolt holes via threaded connectors.

[0006] The aforementioned adaptive and reusable safety protection device for stairwells features a telescopic horizontal tube that can adapt to different stair lengths. This tube is securely connected to the aluminum alloy template via pins. Since the telescopic tube assembly is rotatably connected to the vertical protective posts, after the vertical protective posts are fixed at both ends of the stair section, the telescopic tube assembly rotates around them, forming guardrails on both sides of the stair steps. Finally, fixing plates are used to connect and secure the vertical protective posts and the horizontal telescopic tube assembly, increasing the stability of the telescopic tube assembly and preventing forward and backward displacement. This structural design shortens assembly and disassembly time, significantly improving efficiency. It can be adjusted according to different stair lengths, making it highly adaptable.

[0007] Furthermore, the fixed-end transverse circular tube and the movable-end transverse circular tube are both rotatably connected to the corresponding vertical protective poles through a rotating rod.

[0008] Furthermore, one end of the movable end transverse circular tube is inserted into the fixed end transverse circular tube, and the diameter of the movable end transverse circular tube is smaller than that of the fixed end transverse circular tube.

[0009] Furthermore, the top of the pin piece is welded to the corresponding vertical protective pole through a steel bar head.

[0010] Furthermore, the pin has a pin hole in the middle, and a pin is provided in the middle of the pin hole.

[0011] Furthermore, the middle parts of the fixed end transverse circular tube and the movable end transverse circular tube are both provided with limiting pressure grooves.

[0012] Furthermore, the threaded connection member is a bolt.

[0013] Furthermore, the cross section of the pin is in the shape of an isosceles trapezoid. Attached Figure Description

[0025] Please see Figures 1 to 5This utility model provides an adaptive and adjustable turnaround safety protection device for stairwells, including two vertical protective poles 2, telescopic tube assemblies located in the middle and top of the two vertical protective poles 2, and multiple fixing plates 5. The telescopic tube assembly includes a fixed-end horizontal tube 3 and a movable-end horizontal tube 4. Each vertical protective pole 2 has a pin 8 at its lower end. The outer sides of the fixed-end horizontal tube 3 and the movable-end horizontal tube 4 are rotatably connected to the corresponding vertical protective pole 2. The upper side of the vertical protective pole 2 is provided with multiple first bolt holes 21 at intervals. The outer sides of the fixed-end horizontal tube 3 and the movable-end horizontal tube 4 are respectively provided with multiple second bolt holes 7. The two ends of the fixed-end horizontal tube 3 and the movable-end horizontal tube 4 are respectively connected to the corresponding vertical protective pole 2 through a fixing plate 8. The two ends of the fixing plate 5 are fixed to the adjacent first bolt holes 21 and second bolt holes 7 through threaded connectors 12.

[0026] The aforementioned adaptive and reusable safety protection device for stairwells features a telescopic horizontal tube 4 that can adapt to different stair lengths. This tube is securely connected to the aluminum alloy template via pins 8. Since the telescopic tube assembly is rotatably connected to the vertical protective pole 2, after the vertical protective pole 2 is fixed at both ends of the stair section, the telescopic tube assembly rotates around the vertical protective pole 2, forming protective railings on both sides of the stair step. Finally, fixing plates 5 are used to connect and fix the vertical protective pole 2 to the horizontal telescopic tube assembly, increasing the stability of the telescopic tube assembly and preventing forward and backward displacement. This structural design shortens assembly and disassembly time, significantly improving efficiency. It can be adjusted according to different stair lengths, making it highly adaptable.

[0027] In one embodiment of this utility model, both the fixed-end horizontal tube 3 and the movable-end horizontal tube 4 are rotatably connected to the corresponding vertical protective pole 2 via a rotating rod 10. This ensures that the outer sides of both the fixed-end horizontal tube 3 and the movable-end horizontal tube 4 are rotatably connected to the corresponding vertical protective pole 2.

[0028] In one embodiment of this utility model, one end of the movable end transverse tube 4 is inserted into the fixed end transverse tube 3. The diameter of the movable end transverse tube 4 is smaller than the diameter of the fixed end transverse tube 3, so that the movable end transverse tube 4 can move in the fixed end transverse tube 3, thereby realizing length adjustment.

[0029] In one embodiment of the present invention, the top of the pin 8 is welded to the corresponding vertical protection post 2 via a steel bar head 9. Specifically, the bottom of the vertical protection post 2 is provided with a pin 8 for connecting to the aluminum alloy formwork. The top of the pin 8 is welded to the steel bar head 9, and then firmly welded to the vertical protection post 2 via the steel bar head 9, so that the bottom of the adaptively adjustable turnover safety protection device in the stairwell can have a connection point with the aluminum alloy formwork.

[0030] In one embodiment of the present invention, a pin hole is provided in the middle of the pin piece 8, and a pin 11 is provided in the middle of the pin hole. Specifically, after the aluminum alloy formwork of the stair flight is installed, the pin piece 8 at the bottom of the vertical protective upright 2 is vertically inserted into the aluminum alloy formwork holes at the upper and lower ends of the stair, and the pin piece 11 is inserted and hammered with a hammer to secure it firmly.

[0031] In one embodiment of the present invention, both the fixed end transverse circular tube 3 and the movable end transverse circular tube 4 are provided with a limiting pressing groove 6 in the middle thereof so that the movable end transverse circular tube 3 will not fall off when stretched to the end.

[0032] In one embodiment of this utility model, the threaded connector 12 is a bolt. In use, it is used in conjunction with a nut to fix the fixing plate 5 to the vertical protective pole 2 and the telescopic tube assembly, preventing rotation of the vertical protective pole 2 and the telescopic tube assembly. Specifically, the holes of the multiple second bolt holes 7 are spaced 25mm apart, ensuring that even when the fixed end transverse tube 3 and the moving end transverse tube 4 form different angles with the vertical protective pole 2, the holes on the fixing plate 5 can still be aligned with the holes of the vertical protective pole 2, the fixed end transverse tube 3, and the moving end transverse tube 4, thus ensuring that the threaded connector 12 passes through the holes for fixing.

[0033] In one embodiment of this invention, the cross-sectional shape of the pin 11 is an isosceles trapezoid. This is used in a wedge structure to make the fixing effect more stable after the pin 11 is inserted into the pin piece 8.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
