[0002] At present, steel pipe coupler type external scaffolding is a commonly used auxiliary facility in the construction of building (structure) structure engineering, and safety during use is particularly important.

[0003] When constructing external wall scaffolding and wall parts at construction sites, the traditional method is to use pre-buried steel pipes for connection, which causes great waste. How to reduce the waste of turnover materials is of great significance.

[0004] At present, traditional steel pipe wall ties are extremely wasteful. Specifically, the steel pipes are directly embedded in the concrete during the production process at the construction site, and then directly cut off during demolition. Utility Model Content

[0005] The utility model aims to provide a wall connecting device for a building scaffold, which can be detachably connected with the scaffold and the outer wall. When the scaffold is dismantled, the wall connecting device can be recycled and reused, which reduces the waste of materials and saves construction costs.

[0029] Example

[0030] A wall connecting device for a building scaffold includes a wall connecting device arranged between the scaffold and an outer wall 10, the wall connecting device includes a fixing portion detachably connected to a steel pipe 1 of the scaffold, an installation portion pre-buried in the outer wall 10, and a locking portion for detachably connecting the fixing portion and the installation portion, and the locking portion can adjust the distance between the vertical surface where the scaffold is located and the outer wall 10.

[0031] In this embodiment, Figure 1 As shown, the scaffold is a steel pipe frame 1 located around the house during house construction. It is composed of a number of vertical, horizontal and oblique steel pipes 1 overlapped with each other, which is a frame for workers to work on. After reaching a certain height, in order to ensure the stability of the scaffold and avoid the risk of collapse, a wall connecting device for pulling the scaffold will be set between the scaffold and the outer wall 10. The function of the fixed part of the wall connecting device is to connect the steel pipes 1 of the scaffold. A design that can be quickly installed and disassembled is adopted, so that it can be easily assembled and disassembled when needed, which not only improves the work efficiency, but also makes the use of the wall connecting device more flexible. The installation part is pre-buried in the outer wall 10 to play a role of fixing and supporting. By pre-buried in the outer wall 10, the installation part can be firmly fixed on the outer wall 10 to provide stable support for the scaffold. This method avoids destructive installation on the surface of the outer wall 10, which not only protects the aesthetics of the building, but also ensures the stability of the connection. At the same time, it will not The locking part affects the waterproof performance of the exterior wall 10. The locking part is an intermediate part connecting the fixing part and the installation part. It adopts a detachable design, which is convenient for installation and disassembly when needed. More importantly, the locking part also has an adjustment function, which can adjust the distance between the vertical plane where the scaffolding is located and the exterior wall 10. Because in actual construction, since the vertical planes where the exterior wall 10 and the scaffolding are located cannot be completely parallel, it is necessary to fine-tune the distance between the scaffolding and the exterior wall 10, and then firmly connect the scaffolding to ensure the stability and safety of the scaffolding. In summary, the wall connecting device of the building scaffolding realizes a stable connection and spacing adjustment between the scaffolding and the exterior wall 10 through the coordinated work of the fixing part, the installation part and the locking part, which not only improves the construction efficiency, but also ensures the safety of construction. It is a very practical construction equipment, which realizes a detachable connection with the scaffolding and the exterior wall 10. When the scaffolding is dismantled, the wall connecting device can be recycled and reused, with less waste of materials and saving construction costs.

[0032] Furthermore, the fixing part includes a hook 2 and a pull rod 3, one end of the pull rod 3 is fixedly connected to the hook 2, and the other end is detachably connected to the locking part. The size of the hook 2 is adapted to the steel pipe 1 constituting the scaffolding and is used to hook the steel pipe 1.

[0033] Specifically, Figure 2As shown, the hook 2 is adapted to the steel pipe 1 constituting the scaffolding, and the shape, size and curvature of the hook 2 are precisely calculated to ensure that it can firmly hook the steel pipe 1. This adaptability not only ensures the stability of the connection, but also makes the installation process simpler and faster. The design of the hook 2 may also take into account the anti-slip function to prevent it from falling off due to vibration or external force during use. One end of the pull rod 3 is fixedly connected to the hook 2, and the other end is detachably connected to the locking part to form a stable supporting structure. At the same time, the detachable design allows the scaffolding to be disassembled when not needed, which is convenient for transportation and storage. The material and strength of the pull rod 3 are also strictly selected to ensure that it can withstand the weight and external force of the scaffolding. The other end of the pull rod 3 is detachably connected to the locking part. This connection method makes the assembly and disassembly of the scaffolding more convenient. At the same time, through the adjustment function of the locking part, the length of the pull rod 3 can be easily adjusted, and then the distance between the scaffolding and the outer wall 10 can be adjusted to ensure that the scaffolding can be subjected to the tension of the wall connection device. In summary, the hook 2 and the pull rod 3 in the fixing part are cleverly designed, which not only ensures the stability and strength of the connection, but also makes the assembly and disassembly of the scaffolding simple and quick. This design not only improves the construction efficiency, but also ensures the safety of the construction, reflecting the advancement and practicality of the wall connection device design.

[0034] Furthermore, the pull rod 3 is divided into a smooth circular section 301 and a threaded section 302 . The surface of the threaded section 302 is provided with external threads. The threaded section 302 is detachably connected to the locking portion, and the smooth circular section 301 is fixedly connected to the hook 2 .

[0035] Specifically, Figure 2 As shown, the smooth circle segment 301 is fixedly connected to the hook 2. Since the surface of the smooth circle segment 301 is smooth and has no threads, the connection with the hook 2 can be achieved by welding, riveting or other fastening methods to ensure that the connection between the two is not easy to loosen and can withstand the weight and external force of the scaffolding. The connection between the threaded segment 302 and the locking part is convenient and reliable. The external thread on the surface of the threaded segment 302 can be matched with the corresponding internal thread in the locking part, and fastening is achieved by rotation. This connection method is not only quick to install, but also easy to disassemble, which helps to improve work efficiency. At the same time, due to the good tightness of the threaded connection, loosening caused by vibration or external force during use can be effectively prevented.

[0036] Furthermore, a U-shaped groove 22 is provided at the end of the hook 2 away from the light circle segment 301, and a first pin hole 20 is also provided at the end that passes through the U-shaped groove 22. A blocking rod 17 is hinged at the connection position between the hook 2 and the light circle segment 301. The free end of the blocking rod 17 can be inserted into the U-shaped groove 22, and a second pin hole 21 that is adapted to the first pin hole 20 is provided at the free end. After the first pin hole 20 and the second pin hole 21 are aligned, an adapted pin shaft 18 is inserted inside.

[0037] Specifically, Figure 2 and Figure 3 As shown, a U-shaped groove 22 is provided at the end of the hook 2 away from the light circle segment 301, which not only provides a space for accommodating the free end of the blocking rod 17, but also allows the blocking rod 17 to move flexibly in the U-shaped groove 22. The design of the U-shaped groove 22 also takes into account the cooperation with the blocking rod 17, ensuring that the connection between the two is both stable and easy to operate. In addition, a first pin hole 20 is also provided at the end of the U-shaped groove 22, which facilitates the insertion of the pin shaft 18, making the connection between the hook 2 and the blocking rod 17 more secure. The blocking rod 17 is connected to the connecting position of the light circle segment 301 of the hook 2 by a hinged manner, which allows the blocking rod 17 to rotate at a certain angle relative to the hook 2, and the free end of the blocking rod 17 can be inserted into the U-shaped groove 22, and the free end is provided with a first pin hole 20 for connecting with the first pin hole 20. A pin hole 20 is adapted to a second pin hole 21. When the first pin hole 20 and the second pin hole 21 are aligned, the adapted pin shaft 18 can be inserted to fix the blocking rod 17 on the hook 2. The blocking rod 17 and the hook 2 together form a circular shape. Therefore, the blocking rod 17 is also an arc-shaped rod. This design not only ensures the stability of the connection between the hook 2 and the blocking rod 17, but also makes it easy to disassemble and assemble when needed. Through this design, a stable structure is formed between the hook 2 and the blocking rod 17, which can effectively prevent the hook 2 from falling off the steel pipe 1 due to external force during use. At the same time, the insertion of the pin shaft 18 further enhances the firmness of the connection, making the wall connection device safer and more reliable when bearing the weight and external force of the scaffolding.

[0038] Furthermore, the locking portion includes an adjusting sleeve 16 and a coupling 7. One end of the adjusting sleeve 16 is threadedly connected to the threaded section 302, and the other end is connected to the coupling 7. The coupling 7 is used to connect the adjusting sleeve 16 and the mounting portion.

[0039] Specifically, Figure 1As shown, one end of the adjusting sleeve 16 is threadedly connected to the threaded section 302 of the pull rod 3. This connection method is both firm and convenient to adjust. By rotating the adjusting sleeve 16, the length of the pull rod 3 can be easily adjusted, thereby achieving the adjustment of the distance between the vertical surface where the scaffolding is located and the outer wall 10. This design enables the wall connection device to adapt to different wall thicknesses and scaffolding heights, thereby improving its scope of application and flexibility. The coupling 7 is connected to the other end of the adjusting sleeve 16. Its main function is to connect the adjusting sleeve 16 and the mounting part. The coupling 7 usually has good rotation flexibility and load-bearing capacity, which can ensure the stable connection between the adjusting sleeve 16 and the mounting part, while allowing a certain degree of rotation or swing to adapt to the irregularities of the wall surface. Through the joint action of the adjusting sleeve 16 and the coupling 7, the locking part not only realizes the firm connection between the pull rod 3 and the mounting part, but also makes the distance between the scaffolding and the exterior wall 10 can be easily adjusted. This design not only ensures the structural stability of the wall connection device, but also improves its convenience and flexibility in use. The design of the locking part fully considers the needs of the wall connection device in actual use. Through the combined use of the adjusting sleeve 16 and the coupling 7, the stable connection and distance adjustment between the scaffolding and the exterior wall 10 are achieved.

[0040] Furthermore, a limiting column 4 is fixed in the adjusting sleeve 16, a through hole is provided in the middle of the limiting column 4, an internal thread adapted to the external thread is provided on the inner wall of the through hole, a limiting plate 15 is provided at one end of the threaded section 302 located in the adjusting sleeve 16, the diameter of the limiting plate 15 is larger than the diameter of the through hole, an auxiliary cavity 6 for assisting the rotation of the adjusting sleeve 16 is provided in the middle of the adjusting sleeve 16, and a convex ridge 5 is provided on the circumference of the outer wall of the adjusting sleeve 16.

[0041] Specifically, a solid limiting column 4 is integrally formed in the adjusting sleeve 16, and a through hole is provided in the middle of the limiting column 4. The inner wall of the through hole has an internal thread that matches the external thread, so that the threaded section 302 of the tie rod 3 can pass through the through hole and fit tightly with the internal thread, so that the adjusting sleeve 16 can adjust the length of the tie rod 3 extending into the adjusting sleeve 16 by rotation, thereby realizing the adjustment of the spacing between the scaffolding and the exterior wall 10. The internal and external threads fit tightly and smoothly, ensuring the smoothness and accuracy of the adjustment process. A limiting plate 15 is provided at one end of the threaded section 302 located in the adjusting sleeve 16, and its diameter is larger than the diameter of the through hole. This design plays a limiting role, preventing the tie rod 3 from excessively extending into or pulling out of the adjusting sleeve 16 during the adjustment process, thereby ensuring the stability and safety of the structure. At the same time, in the event of thread slippage between the limiting column 4 and the tie rod 3, the entire wall connection device will not lose its limiting effect on the scaffolding, thereby ensuring the safety of the scaffolding. Figure 1As shown, the auxiliary cavity 6 provided in the middle of the adjusting sleeve 16 facilitates the insertion of tools, so that the staff can use tools such as wrenches to assist the rotation of the adjusting sleeve 16, thereby completing the adjustment operation more easily, and the convex ridges 5 on the circumferential direction of the outer wall of the adjusting sleeve 16 increase the friction force, making it easier and less prone to slipping when manually rotating the adjusting sleeve 16. In summary, these design details in the adjusting sleeve 16 not only improve the structural stability and adjustment accuracy of the wall connection device, but also make the adjustment process more convenient and efficient. These designs fully reflect the in-depth consideration of practicality and operability, and provide strong support for the installation and adjustment of scaffolding during the construction process.

[0042] Furthermore, the mounting portion includes a connecting plate 14 and a fixing seat 11. One side of the connecting plate 14 is fixedly connected to the coupling 7. Assembly holes 19 are provided at four corners of the connecting plate 14. The fixing seat 11 is pre-buried in the outer wall 10. Threaded rods 8 corresponding to the assembly holes 19 are provided at the four corners of the outer side of the fixing seat 11. The threaded rods 8 pass through the assembly holes 19 and connect the connecting plate 14 to the fixing seat 11 through locking nuts 9.

[0043] Specifically, the connection plate 14 is fixedly connected to the coupling 7, and one side of the connection plate 14 is fixedly connected to the coupling 7. This connection method ensures the overall stability of the wall connection device and the continuity of the structure. The connection plate 14 plays a key role as a bridge between the wall connection device and the outer wall 10. The assembly holes 19 opened at the four corners of the connection plate 14 correspond to the threaded rods 8 set at the four corners of the outer side of the fixing seat 11. This design allows the connection plate 14 to be accurately aligned with the fixing seat 11, and the connection is achieved by passing the threaded rod 8 through the assembly hole 19. After the threaded rod 8 passes through the assembly hole 19, the connection plate 14 is fixed by the locking nut 9. Tightly connected with the fixing seat 11, the design of the locking nut 9 makes the connection more firm and reliable, and can effectively prevent loosening and falling off. At the same time, the tightening force of the locking nut 9 can be adjusted as needed to meet the needs of different wall materials and thicknesses. Two locking nuts 9 can be set. During installation, first, the fixing seat 11 is embedded in the outer wall 10, and then the connecting plate 14 is fixedly connected with the coupling 7, and the connecting plate 14 is aligned with the threaded rod 8 on the fixing seat 11. Then, the threaded rod 8 is passed through the assembly hole 19 and fastened with the locking nut 9. In this way, the wall connecting device is firmly connected to the outer wall 10 through the installation part. In summary, the design of the installation part fully considers the stability and convenience of the connection between the wall connecting device and the outer wall 10. Through the combined use of the connecting plate 14, the fixing seat 11, the assembly hole 19, the threaded rod 8 and the locking nut 9, a quick and firm connection is achieved, which provides strong support for the construction of the scaffolding. This design not only improves the construction efficiency, but also ensures the safety of the construction.

[0044] Furthermore, the assembly hole 19 is a waist-shaped hole.

[0045] Specifically, Figure 4 As shown, the waist-shaped hole design of the assembly hole 19 has the following advantages: Adjustment and fault tolerance: The long strip design of the waist-shaped hole allows the connecting plate 14 to have a certain range of horizontal movement during installation. This design is very useful for situations where the wall surface is uneven or there are slight deviations, because it can accommodate these deviations and allow workers to make fine adjustments during the installation process to ensure that the connecting plate 14 is accurately aligned with the fixing seat 11. Reduce stress concentration: Compared with round holes, waist-shaped holes can better disperse forces and reduce stress concentration. This is especially important for wall-connecting devices that bear heavy loads because it helps prevent cracks or damage at the installation site. Ease of installation: The shape of the waist-shaped hole makes it easier for workers to pass the threaded rod 8 through the assembly hole 19 during installation. Compared with traditional round holes, the long strip opening provides a larger operating space and reduces the difficulty of installation.

[0046] Furthermore, a protective rubber sleeve is provided on the threaded rod 8. Specifically, during the construction process, a large amount of concrete may be attached to the threaded rod 8, which is not conducive to the connection of the locking nut 9 in the later stage. The protective rubber sleeve (not shown in the figure) can effectively isolate these unfavorable factors, ensure the cleanliness of the surface of the threaded rod 8, and help improve the assembly efficiency in the later stage. When it is necessary to assemble the connecting plate 14, the protective rubber sleeve is first removed, and then the threaded rod 8 is inserted into the assembly hole 19, and then the locking nut 9 is screwed on to firmly connect the connecting plate 14 to the fixing seat 11.

[0047] Furthermore, a reinforcing rod 12 is provided on the inner side of the fixing seat 11 , and the reinforcing rod 12 is welded to the steel bars in the outer wall 10 , and the outer end of the threaded rod 8 does not extend beyond the outer wall 10 .

[0048] Specifically, Figure 1 As shown, the design of the reinforcing rod 12 in the fixing seat 11 is an important measure to enhance the strength and stability of the structure. The reinforcing rod 12 is welded to the steel bars in the outer wall 10. This connection method ensures the close connection between the wall connecting device and the outer wall 10 structure, effectively transmits and disperses external forces, thereby improving the safety and stability of the entire structure. At the same time, the design that the outer end of the threaded rod 8 does not extend beyond the outer wall 10 takes into account both aesthetics and safety. On the one hand, it prevents the threaded rod 8 from being exposed on the wall, making the surface of the outer wall 10 neater and more beautiful; on the other hand, it also reduces the potential safety hazards caused by the protrusion of the threaded rod 8, such as bumps or scratches on personnel, etc. Figure 5As shown, at the same time, since the fixing seat 11 has a certain area and the threaded rod 8 does not extend beyond the wall surface of the outer wall 10, there is a cavity 13 in the wall, and the cavity 13 allows the connecting plate 14 to extend into it, so as to connect the connecting plate 14 with the fixing seat 11. After the connecting plate 14 is removed at a later stage, there is no need to manually cut off the threaded rod 8, and concrete can be directly filled in the cavity 13, which saves time and effort and reduces the intensity of manual labor. In summary, the design of the reinforcing rod 12 in the fixing seat 11 and the design that the outer end of the threaded rod 8 does not extend beyond the outer wall 10 together improve the overall performance of the wall connection device, which not only ensures the strength and stability of the structure, but also takes into account the aesthetics and safety. It is a very practical innovation in the design of the wall connection device. At the same time, when connecting, since the threaded rod 8 is in the cavity 13 and the space is limited, the connection of the locking nut 9 is achieved by tightening the sleeve.

[0049] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
