DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will describe in detail a ladder cage wall attachment fastening device provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for describing the embodiments more specifically and are not intended to specifically limit the present utility model.

[0023] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an embodiment of the present utility model provides a ladder cage wall attachment fastening device, including: a cylindrical pier 1 and a ladder cage parallel tie rod 4; a scaffolding steel pipe 10 provided on the cylindrical pier 1, and the scaffolding steel pipe 10 includes: a plurality of embedded parts 8 welded to the cylindrical pier 1; a threaded steel bar 7 provided on the embedded part 8; a steel plate gasket 9 installed on the threaded steel bar 7, and the steel plate gasket 9 is in contact with the ladder cage parallel tie rod 4.

[0024] The embedded part 8 is welded to the cylindrical pier 1, the threaded steel bar 7 is provided on the embedded part 8, and the steel plate gasket 9 is installed on the threaded steel bar 7, which plays a role in fastening and supporting. The embedding is convenient and quick. Each time, only one embedded part 8 is lost, and the rest of the accessories can be recycled, reducing the loss and use cost.

[0025] As Figure 1 , Figure 3 and Figure 4 shown, a swivel coupler 2 is installed on the ladder cage parallel tie rod 4 and the threaded steel bar 7 for connecting the ladder cage parallel tie rod 4 and the threaded steel bar 7.

[0026] The function of the swivel coupler 2 is to connect the ladder cage parallel tie rod 4 and the threaded steel bar 7 to achieve the fixation and support of the entire device. Through the swivel coupler 2, problems such as connecting the attached wall in any direction and position and low embedding accuracy of the embedded part 8 can be solved. The construction is flexible, convenient, and has strong practicability.

[0027] As Figure 1 , Figure 3 and Figure 4 shown, a ladder cage diagonal tie rod 3 is installed on the ladder cage parallel tie rod 4; a sleeve 6 is installed on the threaded steel bar 7.

[0028] The ladder cage diagonal tie rod 3 is used to provide additional support and stability to ensure the firmness of the entire device.

[0029] As Figure 1 , Figure 2 and Figure 3 shown, an embedded groove 5 is opened on the cylindrical pier 1 for placing the embedded part 8.

[0030] The function of the embedded groove 5 is to provide an accurate and flat position for placing the embedded part 8, so as to ensure that the embedded part 8 can be accurately installed on the cylindrical pier 1. Through the design of the embedded groove 5, the embedded part 8 can be conveniently fixed in the predetermined position and ensure its firm and reliable connection with the cylindrical pier 1, which can ensure the structural stability and safety of the entire device.

[0031] As Figure 1 shown, the rotating fastener 2 adopts a universal conversion fastener with a diameter change from φ32mm to φ48mm.

[0032] The function of the rotating fastener 2 is to connect structures with different diameters. By using this universal conversion fastener, the connection between structures with different diameters can be realized, making the entire scaffolding system more flexible and adjustable to adapt to different construction requirements and improve construction efficiency and safety.

[0033] As Figure 3 shown, the distance between two adjacent embedded parts 8 is 4.5m.

[0034] The distance of 4.5m between two adjacent embedded parts 8 is to ensure the stability and load-bearing capacity of the entire device. By evenly distributing the embedded parts 8 on the cylindrical pier 1 and maintaining a certain distance, the weight and load of the scaffolding can be effectively dispersed, preventing instability and deformation caused by concentrated load. Such a spacing arrangement can also provide sufficient support points and connection points, enabling the entire device to withstand high loads and stresses under various construction conditions.

[0035] As Figure 1 and Figure 3 shown, the embedded part 8 adopts an embedded part 8 with a diameter of φ32mm, and the parallel tie rod 4 of the cage adopts a φ48mm steel pipe.

[0036] The function of using an embedded part 8 with a diameter of φ32mm for the embedded part 8 is to firmly fix the embedded part 8 on the cylindrical pier 1 to ensure the stability and safety of the entire device. Such an embedded part 8 can avoid problems such as loosening or falling off caused by vibration or other external forces, and improve the service life and reliability of the device.

[0037] The function of using a φ48mm steel pipe for the parallel tie rod 4 of the cage is to provide lateral support force and stability to maintain the balance and firmness of the entire device. The φ48mm steel pipe has sufficient strength and stiffness to withstand high loads and stresses under various construction conditions, ensuring the safety and reliability of the entire device system.

[0038] For the technical solution provided by the present utility model, during use, embed and weld embedded parts 8 at positions every 4.5 m on the cylindrical pier 1, and fix them on the main steel bars to ensure firm and reliable welding. Bind both ends of the embedded parts 8 with tape to prevent concrete slurry from flowing into the embedded parts 8. While embedding the threaded steel bars 7, use a thread rolling machine to roll the heads of the threaded steel bars 7, and the rolling length is equal to the length of the embedded parts 8. During the installation process of the ladder cage, find the position of the embedded parts 8, remove the tape, and use the pre-prepared threaded steel bars 7 and embedded parts 8 to connect them mechanically. Connect the rolled thread heads of the steel bars mechanically in place to ensure that the exposed thread heads do not exceed 2 threads. Fix the connected threaded steel bars 7 to the rotating fasteners 2, and fix the other end of the rotating fasteners 2 to the parallel tie rods 4 of the ladder cage. The end of the ladder cage is fixed with a customized fixing part provided by the manufacturer and fixed with screws to the main vertical pole of the ladder cage, with firm connection and fixation. After the attachment of the wall connecting member to the wall is completed, check the quality of each connection. Pay special attention to the tightening of the screws during the inspection, and ensure that each screw is tightened.

[0039] The present utility model covers any alternatives, modifications, equivalent methods and solutions made within the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without the description of these details. In addition, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components and circuits are not described in detail.

[0040] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
