[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a novel anti-pull and support device suitable for connecting an external scaffolding with a building floor. Figure 1-Figure 4 As shown, it includes a first steel pipe 1 and a second steel pipe 2, which are connected and fixed by two connecting fasteners 5. The bottom end of the first steel pipe 1 is installed on the floor of the building through an embedded component, and the top of the second steel pipe 2 is connected to the external scaffolding. The embedded component includes a fixed steel plate 7, which is fixed to the floor of the building through embedded bolts 3. Two embedded positioning steel plates 6 are installed on the top of the fixed steel plate 7. The embedded positioning steel plates 6 are symmetrically arranged on both sides of the bottom end of the first steel pipe 1 and connected by connecting bolts 4. The middle part of the connecting bolts 4 is rotatably connected to the first steel pipe 1. The utility model is connected and fixed by two connecting fasteners 5 between the first steel pipe 1 and the second steel pipe 2, ensuring the structural stability of the device. At the same time, the bottom end of the first steel pipe 1 is firmly installed on the floor of the building through the embedded component, and the top of the second steel pipe 2 is connected to the external scaffolding, forming a stable and reliable overall support structure. The design of the embedded component makes the installation process of the device easier. The fixed steel plate 7 is fixed to the floor of the building by the embedded bolts 3, and the embedded positioning steel plate 6 is symmetrically arranged on both sides of the bottom end of the first steel pipe 1, and is rotatably connected to the first steel pipe 1 by the connecting bolts 4. This design not only simplifies the installation steps, but also improves the accuracy and efficiency of the installation. Since the device adopts a stable and reliable connection method, and the bottom end of the first steel pipe 1 is firmly installed on the floor of the building, the connection stability between the external scaffolding and the floor of the building is effectively enhanced, thereby improving the safety during the construction process. The design of the device has a certain adaptability and can adapt to external scaffolding and building floors of different sizes and shapes, so that it can be widely used in various construction scenes.

[0023] In this embodiment, embedded bolt holes 71 are provided on the surface of the fixing steel plate 7 near the four corners, and the embedded bolts 3 are fixed to the floor of the building through the embedded bolt holes 71, so as to facilitate the fixing of the embedded bolts 3.

[0024] Specifically, the embedded positioning steel plate 6 is vertically welded to the fixed steel plate 7, and the structure is stable and does not deviate.

[0025] Furthermore, a connecting bolt hole 61 is provided on the surface of the embedded positioning steel plate 6 , and both ends of the connecting bolt 4 are threadedly connected to the connecting bolt hole 61 , so as to facilitate the installation and fixation of the connecting bolt 4 .

[0026] Furthermore, the upper and lower connecting fasteners 5 are annular structures, and the connecting fasteners 5 are sleeved at the connection between the first steel pipe 1 and the second steel pipe 2, and are locked and fixed by locking bolts 51, so as to facilitate the connection and fixation of the first steel pipe 1 and the second steel pipe 2.

[0027] Furthermore, strip holes 11 are provided on the outer walls of both sides of the first steel pipe 1, and stud bolts 52 are provided at the strip holes 11. Both ends of the stud bolts 52 pass through the lower connecting fasteners 5 and are fastened and fixed by nuts, so as to facilitate the axial length adjustment of the first steel pipe 1 and the second steel pipe 2 and the extension and shortening adjustment of the device.

[0028] Furthermore, the diameter of the stud bolt 52 is matched with the width of the strip hole 11 , and the stud bolt 52 and the strip hole 11 are slidably matched to ensure that the first steel pipe 1 and the second steel pipe 2 slide stably in the axial direction.

[0029] When the utility model is used, the new type of anti-pull and support device for connecting the external scaffolding with the floor of the building is firstly selected on the floor of the building, and the embedded bolts 3 are passed through the embedded bolt holes 71 on the surface of the fixed steel plate 7 to firmly fix the fixed steel plate 7 on the floor. The design of the fixed steel plate 7 ensures the stability and load-bearing capacity of the embedded components.

[0030] Next, two embedded positioning steel plates 6 are vertically welded to the top of the fixed steel plate 7 and symmetrically arranged at predetermined positions for subsequent connection with the first steel pipe 1. The connection bolt holes 61 on the embedded positioning steel plates 6 provide accurate positioning for the subsequent installation of the connection bolts 4.

[0031] The bottom end of the first steel pipe 1 is placed between the embedded positioning steel plates 6, and the connecting bolts 4 pass through the connecting bolt holes 61 of the embedded positioning steel plates 6 and are rotatably connected to the first steel pipe 1. This design allows the first steel pipe 1 to be fine-tuned during installation to ensure the accuracy and stability of the connection.

[0032] Two annular connecting fasteners 5 are installed between the first steel pipe 1 and the second steel pipe 2 and sleeved on the connection of the two steel pipes. The connecting fasteners 5 are locked and fixed by locking bolts 51, thereby firmly connecting the first steel pipe 1 and the second steel pipe 2 to form a stable supporting structure.

[0033] As required, the device can be extended or shortened by adjusting the position of the stud bolts 52 in the strip holes 11 on the outer walls of both sides of the first steel pipe 1. Both ends of the stud bolts 52 pass through the lower connecting fasteners 5 and are locked and fixed by nuts to ensure stability after adjustment. The sliding fit between the stud bolts 52 and the strip holes 11 ensures a smooth and stable adjustment process.

[0034] Finally, the top of the second steel pipe 2 is connected to the external scaffolding to complete the installation of the entire support device. At this point, the first steel pipe 1 is firmly installed on the floor of the building through the embedded components, and the second steel pipe 2 forms a stable supporting relationship with the external scaffolding, effectively enhancing the connection stability between the external scaffolding and the floor of the building.
