Description

Technical Field

[0001] This utility model relates to the field of building formwork installation technology, specifically an auxiliary device for installing the outer formwork of a structural column in an open wall. Background Technology

[0002] To enhance the overall stability and seismic performance of buildings and effectively prevent structural damage under external forces such as earthquakes, structural columns are often installed in weak points of masonry structures or secondary structures of frame structures, in accordance with the "Seismic Design Code," to enhance local load-bearing capacity. During an earthquake, structural columns improve the ductility of the walls. By dissipating seismic energy and limiting wall fragmentation displacement, structural columns delay structural collapse, thereby improving the overall stability and seismic performance of the structure. Furthermore, by limiting wall deformation and crack width, they further constrain the propagation of wall cracks.

[0003] Structural columns are typically located at corners between interior and exterior walls, and between windows. Formwork erection for interior structural columns is relatively simple and convenient. However, in the construction of structural columns on interior walls facing open space or on the exterior walls of high-rise buildings, the external protective scaffolding of the main structure and tower cranes used for vertical transportation are usually dismantled, and material transportation relies solely on construction elevators. Therefore, the formwork erection for structural columns on the exterior walls of high-rise buildings must be entirely carried out by workers from inside the building. During this process, there are significant safety and quality risks associated with formwork installation. An "open space wall" refers to a wall with one side directly facing an open space, typically located inside or at a high point on the exterior of a building.

[0004] Therefore, it is necessary to invent an auxiliary device for installing the outer formwork of the structural column of the open wall to solve the above problems. Utility Model Content

[0005] In order to solve the safety and quality problems existing in the formwork erection process of structural columns of exterior walls or interior open walls of high-rise buildings, this utility model provides an auxiliary device for the installation of the outer formwork of structural columns of open walls.

[0006] This utility model is achieved using the following technical solution: An auxiliary device for installing the outer formwork of a structural column in an open-air wall includes a controller and a telescopic adjustable base. Two square steel columns are fixed to the upper surface of the telescopic adjustable base. Each square steel column has a limiting square steel sleeve I installed at its top. A telescopic square steel I is slidably inserted into each limiting square steel sleeve I. A telescopic hydraulic rod I is provided between the telescopic square steel I and the corresponding limiting square steel sleeve I. The fixed end of the telescopic hydraulic rod I is fixed to the outer surface of the tail end of the corresponding limiting square steel sleeve I. The moving end of the telescopic hydraulic rod I is hinged to the outer surface of the first end of the corresponding telescopic square steel I. A winch is installed on the top of each limiting square steel sleeve I, and a wire rope is wound on the drum of the winch. A lifting device is connected to the first end of each wire rope. An external hanging basket is installed at the lower end of each lifting device. A fixed pulley is installed at the first end of each telescopic square steel I. Each wire rope is connected to the lifting device after changing direction through the corresponding fixed pulley. A counterweight is hung at the tail end of each limiting square steel sleeve I. The telescopic adjustable base includes a telescopic hydraulic rod II, a fixed-end flatbed trolley, and a mobile-end flatbed trolley. Two square steel columns are fixed to the upper surface of the fixed-end flatbed trolley and the upper surface of the mobile-end flatbed trolley, respectively. The fixed end of the telescopic hydraulic rod II is fixed to the upper surface of the fixed-end flatbed trolley, and the mobile end of the telescopic hydraulic rod II is hinged to the upper surface of the mobile-end flatbed trolley. The controller is electrically connected to telescopic hydraulic rod I, telescopic hydraulic rod II, and winch, respectively.

[0007] Furthermore, a limiting square steel sleeve II is fixed on the upper surface of the mobile end flatbed trolley, and a telescopic square steel II is slidably inserted inside the limiting square steel sleeve II, with the first end of the telescopic square steel II fixed to the upper surface of the fixed end flatbed trolley.

[0008] Furthermore, both the fixed-end flatbed trolley and the mobile-end flatbed trolley include a base plate, and the bottom end of the base plate is equipped with rollers via rollers.

[0009] Furthermore, several hydraulic outriggers are installed around the base plate, and the hydraulic valves and hydraulic pumps of the hydraulic outriggers are electrically connected to the controller.

[0010] Furthermore, the top of the square steel column is hinged to the corresponding limiting square steel sleeve I, and a telescopic hydraulic rod III is provided between the square steel column and the corresponding limiting square steel sleeve I. The fixed end of the telescopic hydraulic rod III is hinged to the outer surface of the corresponding square steel column, and the moving end of the telescopic hydraulic rod III is hinged to the lower surface of the corresponding limiting square steel sleeve I. The telescopic hydraulic rod III is electrically connected to the controller.

[0011] Furthermore, connecting plates are welded to both sides of the lower end of the lifting device, and L-shaped connecting rods are welded to the bottom of the connecting plates. Diagonal braces are provided on the inner side of the L-shaped connecting rods, and the bottom inner side of the L-shaped connecting rods is welded and fixed to the outer side of the external hanging basket.

[0012] This utility model features a reasonable and reliable structural design, enabling the deployment of formwork on the exterior of structural columns in exposed walls within the building floors and allowing for external construction work. Workers can safely work within the external suspended scaffold, avoiding the risks of leaning out at heights and resolving the safety hazards caused by scaffold dismantling in traditional construction. The combined design of the telescopic hydraulic rod I, telescopic square steel I, and limiting square steel sleeve I allows for the horizontal extension and retraction of the external suspended scaffold. The winch and wire rope system precisely control the height of the external suspended scaffold, while fixed pulleys and counterweights ensure stable operation. The telescopic adjustable base allows for adjustment of the spacing of the external suspended scaffold, enhancing adaptability. The controller centrally controls all actions, making operation convenient. This device significantly improves the construction safety, installation quality, and efficiency of the external formwork for structural columns in exposed walls, and has good potential for widespread application.

[0016] An auxiliary device for installing the outer formwork of a structural column in an open wall, as shown in the attached document. Figure 1 ~Appendix Figure 2As shown, the device includes a controller and a telescopic adjustable base. Two square steel columns 1 are fixed to the upper surface of the telescopic adjustable base. Each square steel column 1 has a limiting square steel sleeve I2 installed on its top. A telescopic square steel I3 is slidably inserted into each limiting square steel sleeve I2. A telescopic hydraulic rod I4 is provided between the telescopic square steel I3 and the corresponding limiting square steel sleeve I2. The fixed end of the telescopic hydraulic rod I4 is fixed to the outer surface of the tail end of the corresponding limiting square steel sleeve I2, and the moving end of the telescopic hydraulic rod I4 is hinged. On the outer surface of the first end of the corresponding telescopic square steel I3, a winch 5 is installed at the top of each limiting square steel sleeve I2, and a wire rope 6 is wound on the drum of the winch 5. The first end of each wire rope 6 is connected to a lifting device 21, and an external hanging basket 7 is installed at the lower end of each lifting device 21. A fixed pulley 8 is installed at the first end of each telescopic square steel I3, and each wire rope 6 is connected to the lifting device 21 after changing direction through the corresponding fixed pulley 8. A counterweight 9 is hung at the tail end of each limiting square steel sleeve I2. The telescopic adjustable base includes a telescopic hydraulic rod II 10, a fixed-end flatbed trolley 11, and a moving-end flatbed trolley 12. Two square steel columns 1 are respectively fixed to the upper surface of the fixed-end flatbed trolley 11 and the upper surface of the moving-end flatbed trolley 12. The fixed end of the telescopic hydraulic rod II 10 is fixed to the upper surface of the fixed-end flatbed trolley 11, and the moving end of the telescopic hydraulic rod II 10 is hinged to the upper surface of the moving-end flatbed trolley 12. The controller is electrically connected to the telescopic hydraulic rod I4, the telescopic hydraulic rod II10, and the winch 5, respectively.

[0017] In this invention, the telescopic adjustable base forms the mobile foundation platform for the entire device. The telescopic hydraulic rod II10 pushes the mobile end flatbed trolley 12 to extend and retract horizontally, adjusting the distance between the two square steel columns 1, thereby adjusting the distance between the two external suspended baskets 7 and their working range. The hoisting system, composed of the winch 5, wire rope 6, fixed pulley 8, and external suspended baskets 7, enables the vertical lifting and lowering of the external suspended baskets 7. Workers can safely stand on the external suspended baskets 7 to install the outer formwork, avoiding high-altitude suspended operations and greatly improving safety. The counterweight 9 is used to balance the overturning moment generated when the external suspended baskets 7 extend out of the window, preventing the device from overturning due to a shift in the center of gravity, ensuring overall structural stability and operational safety. The controller enables one-button operation on-site, improving operational convenience and accuracy, and reducing the risk of human error.

[0018] Addressing the risks of falls, operational inconvenience, and quality assurance associated with installing formwork for exterior walls or exposed walls of high-rise buildings after the scaffolding has been removed, tower cranes have been withdrawn, and workers must extend from indoors to work, this device enables a fully indoor deployment and outdoor operation mode. This eliminates the need for workers to climb or work in mid-air, fundamentally resolving safety hazards. Simultaneously, mechanized lifting and movement improve installation efficiency and precision, ensuring the quality of formwork installation.

[0019] The upper surface of the mobile flatbed trolley 12 is fixed with a limiting square steel sleeve II 13, and a telescopic square steel II 14 is slidably inserted inside the limiting square steel sleeve II 13. The first end of the telescopic square steel II 14 is fixed to the upper surface of the fixed flatbed trolley 11.

[0020] When the telescopic hydraulic rod II10 pushes the mobile end flatbed trolley 12 to move horizontally, the limiting square steel sleeve II13 and the telescopic square steel II14 provide precise guidance to prevent the mobile end flatbed trolley 12 from deviating, getting stuck or twisting during the extension and retraction process, ensuring that the entire base extends and retracts smoothly, synchronously and reliably.

[0021] Both the fixed-end flatbed trolley 11 and the mobile-end flatbed trolley 12 include a base plate, and the bottom end of the base plate is equipped with rollers via rollers.

[0022] Several hydraulic outriggers 16 are installed around the base plate, and the hydraulic valves and hydraulic pumps of the hydraulic outriggers 16 are electrically connected to the controller.

[0023] Once the device is in place, the hydraulic valves and hydraulic pumps are activated via the controller, causing the hydraulic outriggers 16 to extend and support the ground. This transforms the entire device from a roller state to a fixed support state, eliminating the swaying caused by the rollers and enhancing overall stability.

[0024] The top of the square steel column 1 is hinged to the corresponding limiting square steel sleeve I2 via a perforated pin 19 and a pin 20. A telescopic hydraulic rod III15 is provided between the square steel column 1 and the corresponding limiting square steel sleeve I2. The fixed end of the telescopic hydraulic rod III15 is hinged to the outer surface of the corresponding square steel column 1, and the moving end of the telescopic hydraulic rod III15 is hinged to the lower surface of the corresponding limiting square steel sleeve I2. The telescopic hydraulic rod III15 is electrically connected to the controller.

[0025] The telescopic hydraulic rod Ⅲ15 can drive the limiting square steel sleeve Ⅰ2 to rotate around the hinge point, thereby adjusting the pitch angle of the limiting square steel sleeve Ⅰ2 relative to the square steel column 1.

[0026] The lower end of the lifting device 21 is welded with connecting plates 17 on both sides. An L-shaped connecting rod 22 is welded to the bottom of the connecting plate 17. An inclined brace 18 is provided on the inner side of the L-shaped connecting rod 22. The bottom inner side of the L-shaped connecting rod 22 is welded and fixed to the outer side of the external hanging basket 7.

[0027] During construction, after the main structure is completed and the secondary structure aerated concrete retaining wall has been built, toothed joints are left at the location of the structural columns for the binding of the structural column reinforcement. After the above procedures are completed, the formwork installation begins. First, the device is moved to the concrete floor slab next to the target window or construction opening using rollers. The hydraulic valves and hydraulic pumps of the hydraulic outriggers 16 of the fixed-end flatbed trolley 11 are then activated, causing the hydraulic outriggers 16 to automatically extend and press against the floor slab surface, completing the switch of the fixed-end flatbed trolley 11 from roller state to fixed support state. Then, the device is closed. The hydraulic valves and hydraulic pumps of the hydraulic outriggers 16 of the fixed-end flatbed trolley 11 are activated; then the telescopic hydraulic rod II 10 is activated to push the moving-end flatbed trolley 12 outward. Under the guidance of the limiting square steel sleeve II 13 and the telescopic square steel II 14, the distance between the two square steel columns 1 gradually increases. When the design distance is reached, the telescopic hydraulic rod II 10 is closed, and at the same time, the hydraulic valves and hydraulic pumps of the hydraulic outriggers 16 of the moving-end flatbed trolley 12 are activated, so that the hydraulic outriggers 16 automatically extend and press against the floor slab surface, and the hydraulic valves of the hydraulic outriggers 16 of the moving-end flatbed trolley 12 are closed. The door and hydraulic pump complete the switching of the mobile flatbed trolley 12 from roller mode to fixed support mode; after confirming that the device is stable, start the telescopic hydraulic rod III 15 to adjust the angle of the limiting square steel sleeve I 2, and close it after keeping the limiting square steel sleeve I 2 horizontal; then start the telescopic hydraulic rod I 4 and adjust the extension length of the telescopic square steel I 3 so that the external suspended basket 7 is located outside the target window or construction opening, that is, outside the work area, and close the telescopic hydraulic rod I 4; then start the winch 5 to release the wire rope 6, which is turned by the fixed pulley 8 and lifts the external suspended basket. 7. Lower to a suitable working height and shut off the winch 5; the workers enter the external suspended basket 7 to install the outer formwork. After the work is completed, the wire rope 6 is retrieved by the winch 5, and the external suspended basket 7 is returned to the room by the telescopic hydraulic rod I4. When the external suspended basket 7 is safely and smoothly returned to the room and reliably stopped on the concrete floor slab, the workers walk out of the external suspended basket 7, thus completing the use of this device; it overcomes the safety and quality hazards existing in the formwork erection process of the structural columns of the exterior walls or interior open walls of existing high-rise buildings.

[0028] It is important to note that the external suspended platform 7 is a specialized device that complies with the national standard "Suspended Platforms for High-Altitude Operations" (GB / T 19155-2017). It is equipped with a comprehensive safety protection system, including safety locks, independent safety rope and safety belt attachment points, upper limit switches, and extreme limit switches. Before entering the external suspended platform 7, workers must re-check the platform's stability, safety ropes, safety belts, limit devices, and counterweight 9 to ensure they are intact and effective, and that the platform is completely stable and in a safe working condition. Only after the platform is completely stable and secured in the work position can workers put on their safety belts and enter the platform from the floor.

[0029] In specific implementation, for buildings with relatively high floor heights, i.e., buildings with floor heights greater than 3 meters, the formwork is difficult to control due to the relatively high height of the structural columns on the exposed walls. Therefore, two external suspended scaffolds 7 can be adjusted to different heights, allowing two people to work together. For the structural columns on the exposed walls of buildings with floor heights not exceeding 3 meters, one external suspended scaffold 7 can be used alone with one worker to complete the outdoor installation. In addition, the outer surface of the square steel column 1 is equipped with a telescopic hydraulic rod I switch, a telescopic hydraulic rod II switch, a winch switch, a telescopic hydraulic rod III switch, a hydraulic valve switch, and a hydraulic pump switch. The controller is located inside the square steel column 1, and the controller is electrically connected to the telescopic hydraulic rod I switch, the telescopic hydraulic rod II switch, the winch switch, the telescopic hydraulic rod III switch, the hydraulic valve switch, and the hydraulic pump switch, respectively.
