Description

Technical Field

[0001] This invention relates to the field of construction formwork climbing technology, and more specifically, to a multifunctional connecting device and climbing platform for climbing formwork. Background Technology

[0002] Climbing formwork refers to a construction method that uses a climbing system to move formwork layer by layer upwards during building construction. It is widely used in the construction of high-rise buildings and large structures, such as skyscrapers, bridges, and chimneys.

[0003] During the construction climbing formwork process, the first step is to build and install a stable climbing system, including a climbing frame, support structure, and hydraulic system. These systems provide the climbing mechanism and support structure, enabling the formwork to move upwards smoothly.

[0004] The formwork is then installed onto the climbing system, which moves upwards layer by layer to install the formwork and pour the concrete. Once the work on one floor is completed, the entire climbing system is raised to the next floor, and the same process is repeated.

[0005] Modern architectural structures are becoming increasingly diverse and artistic. Many buildings utilize openwork wall structures to enhance aesthetics, such as arranging multiple concrete columns in a plum blossom pattern. This structure not only improves the building's appearance but also maximizes space and increases structural stability through the intersection of the columns. This type of intersecting concrete column structure is also seen in bridge construction. Typically, when pouring such a structure, depending on the column axis, construction workers need to adjust the connection between the formwork and the climbing formwork device or change the formwork type. Whether adjusting or replacing the formwork, workers need to further adjust the connection method, or even replace the connection structure altogether. This makes the construction process complex and time-consuming. Summary of the Invention

This multi-functional connecting device can drive the formwork to rotate, thereby changing the formwork's length direction to adapt to the pouring of cement columns with different axial directions. At the same time, it can also drive the formwork to rise and fall to achieve more precise positioning of the formwork. This eliminates the need for reconnecting the formwork and does not require construction personnel to adjust the connection method or even replace the connection structure, thereby simplifying construction and saving construction time.

[0062] Please refer to the following: Figures 1-2 , Figure 4 and Figure 8 In a first aspect, embodiments of this application provide a multifunctional connecting device for climbing formwork, comprising a lifting guide rail 100, a lifting slider 101, a first driving assembly 102, a template connector 103, and a second driving assembly 104; the lifting slider 101 includes a driving slider 1011 and a limiting slider 1012, the driving slider 1011 and the limiting slider 1012 being connected and spaced apart, and the driving slider 1011 and the limiting slider 1012 respectively slidingly engaging with the lifting guide rail 100; the first driving assembly... 102 is connected to the lifting slider 101 to drive the lifting slider 101 to slide on the lifting guide rail 100; the template connector 103 is provided with an annular groove 1031, and a circumferential slider 110 is arranged in the annular groove 1031, and the circumferential slider 110 is connected to the driving slider 1011; the second driving component 104 is connected to the limiting slider 1012, and it is connected to the template connector 103 to drive the template connector 103 to rotate, wherein the rotation center axis of the template connector 103 coincides with the axis of the annular groove 1031.

[0063] In this embodiment, the lifting guide rail 100 is installed vertically, that is, the length direction of the lifting guide rail 100 is perpendicular to the horizontal plane. The lifting guide rail 100 can be in the shape of a cuboid. A sliding hole is opened at the middle position in the width direction. The length direction of the sliding hole is parallel to the length direction of the lifting guide rail 100, and the length of the sliding hole is adaptively designed according to the lifting height requirements. The side wall of the sliding hole, which is perpendicular to the width direction of the lifting guide rail 100, extends to both sides to form a guide rail groove together with the sliding hole. The shapes of the drive slider 1011 and the limit slider 1012 are adapted to the shape of the guide rail groove to achieve sliding fit. The multiple groove walls of the guide rail groove can limit the drive slider 1011 and the limit slider 1012 in multiple directions to ensure that they have good load-bearing performance, so that they can be used in relatively heavy-load occasions. In actual implementation, the overall thickness of the lifting guide rail 100 can be designed according to the conventional maximum weight of the template to ensure structural strength. At the same time, steel ball 1102 retainers can be set on the drive slider 1011 and the limit slider 1012 to abut against the guide rail groove to improve the smoothness of the sliding of the drive slider 1011 and the limit slider 1012, prevent jamming, and facilitate the adjustment of the height position of the template, which can improve the accuracy of template height adjustment to a certain extent. The first drive assembly 102 can be configured as a hydraulic telescopic cylinder to provide a larger lifting force. The length direction of the hydraulic telescopic cylinder is parallel to the length direction of the guide rail groove. The hydraulic telescopic cylinder can be connected to one side of the lifting guide rail 100. A lifting frame 109 is connected to the movable rod of the hydraulic telescopic cylinder. The lifting frame 109 is generally U-shaped. One end of the lifting frame 109 is fixedly connected to the movable rod, and the other end moves through the lifting guide rail 100 and is located in the guide rail groove and is fixedly connected to the drive slider 1011 to drive the drive slider 1011 to move up and down. In this way, the vertical height of the template can be adjusted.In this embodiment, the template connector 103 can be constructed as a circle. Multiple weight-reducing holes can be provided on the template connector 103 to reduce the bearing pressure on the drive slider 1011 and the limiting slider 1012. The radius of the annular groove 1031 on the template connector 103 is smaller than the distance between the drive slider 1011 and the limiting slider 1012. The line connecting the drive slider 1011 and the circumferential slider 110 and the length direction of the guide rail groove are both located in the same vertical plane. Thus, when the drive slider 1011 is connected to the circumferential slider 110, the drive slider 1011 can provide pressure to the template connector 103. The tensile force forming an angle with the horizontal direction, the vertical component of which can directly resist the weight of the template connector 103 and the template, can significantly reduce the bending moment pressure exerted by the weight of the template connector 103 and the template on the second drive assembly 104. Since the second drive assembly 104 is a transmission device, it has high requirements for transmission accuracy and fit accuracy in its structure. Therefore, when the bending moment on the second drive assembly 104 is significantly reduced, the second drive assembly 104 can be guaranteed to operate stably for a long time, thus adapting to the application environment of long construction cycles such as concrete pouring. After the template is connected to the template connector 103, the template connector 103 is rotated by the second drive assembly 104. Since the axis of the annular slide 1031 coincides with the rotation center axis of the second drive assembly, the circumferential slider 110 can slide synchronously in the annular slide 1031, thereby realizing the adjustment of the rotation angle of the template.

[0064] During the process of concrete pouring and forming, the surface will expand or contract to a certain extent. Therefore, the template and template connector 103 will bear a certain tensile or thrust force during the concrete forming process. Therefore, in this embodiment, connecting the drive slider 1011 with the circumferential slider 110 not only provides tension to the template connector 103 and realizes the rotation of the template connector 103, but also resists the tensile or thrust force applied by the concrete. This reduces the thrust or tension force borne by the second drive assembly 104 in the rotation axis, thereby preventing the transmission function or transmission accuracy of the second drive assembly 104 from being damaged or even the structure from being damaged.

[0065] Because the template is heavy, the smoothness of sliding between the template connector 103 and the circumferential slider 110 during rotation needs to be considered. If only the conventional method of reducing the roughness of the contact surfaces is used, they may adhere to each other under heavy load conditions. If the roughness of the contact surfaces is reduced while reducing the contact area, they may wear against each other under heavy load conditions. Therefore, in some embodiments, please refer to... Figure 4The circumferential slider 110 specifically includes a slider body 1101 and steel balls 1102. The length direction of the slider body 1101 is an arc shape adapted to the annular groove 1031. Several steel balls 1102 are respectively fitted on the inner and outer arc surfaces of the slider body 1101 through a groove locking ball process. The arrangement of steel balls 1102 reduces the contact area between the circumferential slider 110 and the annular groove 1031. At the same time, the frictional resistance between the two is rolling friction, which reduces the rotational resistance of the template connector 103 and ensures the smooth sliding between the template connector 103 and the circumferential slider 110.

[0066] In some embodiments, there are two drive sliders 1011, which are located on both sides of the limiting slider 1012; there are two circumferential sliders 110, which are connected to the two drive sliders 1011 respectively.

[0067] In specific implementation, the two driving sliders 1011 can be arranged symmetrically about the limiting slider 1012, that is, the distance between each driving slider 1011 and the limiting slider 1012 is greater than the radius of the annular groove 1031. The arrangement of the two driving sliders 1011 can not only further reduce the bending moment borne by the second driving device, but also enhance the rotational stability of the template connector 103. At the same time, when the two driving sliders 1011 exert force on the template connector 103 together, the force on the template connector 103 in the rotational axis of the second driving assembly 104 is more balanced. Thus, during the concrete molding process, the tensile or pushing force exerted by the concrete on the template connector 103 is less likely to cause the template connector 103 to deviate. Therefore, the second driving assembly 104 will not bear additional bending moment during the concrete molding process.

[0068] Of course, the number of drive sliders 1011 is not limited to two, and can be set to more than two, as needed. In actual implementation, multiple concentric annular grooves 1031 can be opened on the template connector 103. One or two annular sliders can be set in each annular groove 1031. The annular sliders in each annular groove 1031 are connected to the corresponding drive sliders 1011. This can further share the bending moment borne by the second drive device due to the gravity of the template and template connector 103. At the same time, the cooperation of multiple annular grooves 1031 and circumferential sliders 110 can further restrict the template connector 103 and improve the rotational stability of the template connector 103. Meanwhile, the installation position of the drive slider 1011 is not limited to the guide rail groove. For example, in some embodiments, an auxiliary groove can also be provided on the lifting guide rail 100. The length direction of the auxiliary groove is parallel to the length direction of the guide rail groove and located on one side of the guide rail groove. The drive slider 1011 slides in the auxiliary groove. The drive slider 1011 in the auxiliary groove and the drive slider 1011 in the guide rail groove can be fixedly connected by a connecting rod to achieve different lifting. The drive slider 1011 in the auxiliary groove is connected to the circumferential slider 110. The line connecting the drive slider 1011 in the auxiliary slide groove and the circumferential slider 110 is located in the same horizontal plane. That is, the drive slider 1011 in the guide rail slide groove drives the template connector 103 to move up and down, while the drive slider 1011 in the auxiliary slide groove can limit the template connector 103 in the left and right directions. Since the drive slider 1011 in the auxiliary slide groove does not have to bear the weight of the template connector 103 and the template, the angle between the line connecting the drive slider 1011 in the auxiliary slide groove and the circumferential slider 110 and the vertical plane can be unrestricted.

[0069] In the above embodiments, if the angle between the line connecting the drive slider 1011 and the circumferential slider 110 in the guide rail groove and the horizontal plane is different, different directions of tension can be provided to the template connector 103. The magnitude of the vertical component of the tension varies depending on the angle. For example, the larger the angle, the larger the vertical component of the tension, and the more gravity it can resist. Therefore, for templates of different sizes, if the angle between the line connecting the drive slider 1011 and the circumferential slider 110 in the guide rail groove and the horizontal plane can be adjusted, the ease of use of the connecting device can be improved. Therefore, in some embodiments, reference can be made together. Figure 1 and Figure 3 The drive slider 1011 and the circumferential slider 110 are connected by a first telescopic component 105, wherein the fixed end and the movable end of the first telescopic component 105 are respectively hinged to the drive slider 1011 and the circumferential slider 110; the drive slider 1011 and the limiting slider 1012 are connected by a second telescopic component 106.

[0070] In this embodiment, the larger the angle between the length direction of the first telescopic component 105 and the horizontal plane, the greater the vertical component of the tension it provides to the template connector 103, and the more gravity it can directly resist. The small component of gravity is resisted by the structural rigidity of the first telescopic component 105 itself, that is, the small component of gravity manifests as a certain bending moment on the first telescopic component 105. Therefore, when the drive slider 1011 and the circumferential slider 110 in the guide rail groove are connected through the first telescopic component 105, the design that the line connecting the drive slider 1011 and the circumferential slider 110 in the guide rail groove forms an angle with the horizontal plane can not only resist the multiple parts of the gravity of the template connector 103 and the template, thus reducing the bending moment borne by the second drive component 104, but also reduce the bending moment borne by the first telescopic component 105 itself.

[0071] For actual implementation, please refer to Figure 5The first telescopic assembly 105 may include a first telescopic cylinder 1051, a first telescopic rod 1052, a first support member 1053, a second support member 1054, and a closing drive assembly 1057. The first telescopic rod 1052 is movably inserted into the first telescopic cylinder 1051 to form a sliding fit. The first telescopic rod 1052 and the first telescopic cylinder 1051 may be configured as hydraulic cylinders to ensure ease of access. The first support member 1053 is generally elongated, with one end extending to both sides to form a first rotating column. A first rotating seat may be provided at the end of the first telescopic rod 1052, and a second support member 1054 may be formed on the first rotating seat. A first mating hole is adapted to a rotating column, the first rotating column is movably inserted into the first mating hole, and a first torsion spring is connected between the first rotating column and the hole wall of the first mating hole to form an elastic hinge. The other end of the first support member 1053 has a first clamping ring 1055 suitable for radially clamping the first telescopic cylinder 1051. The first clamping ring 1055 can be specifically configured as a semi-circular steel plate. The second support member 1054 can also be elongated, with one end extending to both sides to form a second rotating column. A second rotating seat can be provided on the end of the second telescopic rod, and a second rotating column adapted to the second rotating column can be formed on the second rotating seat. The second rotating post is movably inserted into the second mating hole, and a second torsion spring is connected between the second rotating post and the hole wall of the second mating hole to form an elastic hinge. The other end of the second support member 1054 has a second clamping ring 1056 suitable for radially clamping the first telescopic cylinder 1051. The second clamping ring 1056 can also be configured as a semi-circular steel plate. The first clamping ring 1055 and the second clamping ring 1056 together form a non-closed circle, that is, when the first clamping ring 1055 and the second clamping ring 1056 simultaneously form radial clamping of the first telescopic cylinder 1051, the first clamping ring 1055 and the second clamping ring 1056... The ends do not contact each other, so that even if the first clamping ring 1055 and / or the second clamping ring 1056 undergo a certain deformation, they can still form a stable clamp on the first telescopic cylinder 1051. The second support member 1054 and the first support member 1053 are respectively located on the radial sides of the first telescopic rod 1052, and a clamping gap suitable for radially clamping the first telescopic rod 1052 is formed between the first clamping ring 1055 and the second clamping ring 1056. The closing drive assembly 1057 is movably connected to the first clamping ring 1055 and the second clamping ring 1056 respectively and is used to drive the first clamping ring 1055 and the second clamping ring 1056 to move closer to each other.During the process of bringing the first clamping ring 1055 and the second clamping ring 1056 closer together using the closing drive assembly 1057, the first clamping ring 1055 and the second clamping ring 1056 can clamp the first telescopic cylinder 1051. In this way, the first support member 1053 and the second support member 1054 can resist the bending moment formed by the template and the template connector 103 on the first telescopic assembly 105 as a whole, thereby reducing the load-bearing pressure on the first telescopic rod 1052 and the first telescopic cylinder 1051, and preventing the first telescopic rod 1052 and / or the first telescopic cylinder 1051 from deforming and damaging the telescopic function. When the attraction of the closing assembly on the first clamping ring 1055 and the second clamping ring 1056 is released, the first support member 1053 and the second support member 1054 move away from each other under the action of the first torsion spring and the second torsion spring. At this time, the first telescopic rod 1052 can slide freely in the first telescopic cylinder 1051.

[0072] In order to reduce space occupancy and improve ease of operation, some implementation methods can be referred to Figure 6 The closing drive assembly 1057 may include a mounting plate 10571, a first guide post 10572, a second guide post 10573, an electromagnet 10574, a first return spring 10575, and a second return spring 10576. The mounting plate 10571 may be rectangular. A mounting plate 10571 may be disposed between the two ends of the first clamping ring 1055 and the second clamping ring 1056. The two ends of the first clamping ring 1055 may be connected to two first attraction plates with surfaces parallel to the mounting plate 10571, and the two ends of the second clamping ring 1056 may also be connected to two second attraction plates with surfaces parallel to the mounting plate 10571. The two surfaces of the mounting plate 10571 are a first mounting surface and a second mounting surface, respectively. The mounting plate 10571 has a mounting hole extending from the first mounting surface through the second mounting surface. The first guide post 10572... One end of the first guide post 10573 can be perpendicularly connected to the first mounting surface, and the other end can move through the first attraction plate on the first clamping ring 1055; one end of the second guide post 10573 can be perpendicularly connected to the second mounting surface, and the other end can move through the second attraction plate on the second clamping ring 1056; the electromagnet 10574 is disposed in the mounting hole and can attract the first clamping ring 1055 and the second clamping ring 1056 respectively; the first return spring 10575 is sleeved on the first guide post 10572 and one end of it is connected to the first clamping ring 1055, and the other end is connected to the other end of the first guide post 10572; the second return spring 10576 is sleeved on the second guide post 10573 and one end of it is connected to the second clamping ring 1056, and the other end is connected to the other end of the second guide post 10573, wherein the structural dimensions of the first return spring 10575 and the second return spring 10576 are set to be the same.

[0073] In this embodiment, the first torsion spring and the second torsion spring serve to ensure that the first support member 1053 and the second support member 1054 are far apart. The structural dimensions of the first torsion spring and the second torsion spring can be set to be the same, and the structural dimensions of the first support member 1053 and the second support member 1054 can also be set to be the same. The arrangement of the first return spring 10575 and the second return spring 10576 further ensures that the distance between the first attraction plate and the second attraction plate and the mounting plate 10571 is the same, provided that the first support member 1053 and the second support member 1054 are far apart. Simultaneously, the attractive force required to drive the first clamping ring 1055 and the second clamping ring 1056 is also the same. Thus, when the electromagnet 10574 attracts the first... The first and second suction plates ensure that the first support 1053 and the second support 1054 operate simultaneously and clamp the first telescopic cylinder 1051 at the same time. This ensures that the first telescopic cylinder 1051 is under balanced force. Because the template is heavy, the electromagnet 10574 has a large attraction force to ensure that the first clamping ring 1055 and the second clamping ring 1056 can stably clamp the first telescopic cylinder 1051. Therefore, the simultaneous operation of the first clamping ring 1055 and the second clamping ring 1056 can prevent the first telescopic cylinder 1051 from being subjected to unilateral impact, which would cause the first telescopic cylinder 1051 to deform or be damaged. This ensures that the first telescopic rod 1052 and the first telescopic cylinder 1051 can slide normally against each other.

[0074] In some implementation methods, see [reference] Figure 2The second drive assembly 104 may specifically include a rotary drive source 1041 and a drive mounting base 1042. The rotary drive source 1041 may be configured as a motor, wherein the drive shaft 1043 of the motor is movably mounted on the limiting slider 1012, and the drive shaft 1043 is connected to the template connector 103. The rotary drive source 1041 is mounted on the drive mounting base 1042, and the drive mounting base 1042 is slidably connected to the lifting guide rail 100. The sliding direction of the drive mounting base 1042 is parallel to the sliding direction of the limiting slider 1012. Specifically, a first sliding guide rail and a second sliding guide rail may be arranged parallel to each other on both sides of the guide rail groove. The two ends of the drive mounting base 1042 may be configured as slider structures adapted to the first sliding guide rail and the second sliding guide rail and slide in cooperation with the first sliding guide rail and the second sliding guide rail. In other words, the motor and the template connector 103 are located on both sides of the lifting guide rail 100, so there is no need to reserve installation space for the motor between the template connector 103 and the lifting guide rail 100. The distance between the template connector 103 and the lifting guide rail 100 can be set to be smaller, so the length of the first telescopic component 105 can be set to be shorter. At the same time, the length of the drive shaft 1043 located between the template connector 103 and the lifting guide rail 100 is also shorter. The lever arm of the first telescopic component 105 and the drive shaft 1043 relative to the template and the template connector 103 is smaller, thereby preventing the first telescopic component 105 and the drive shaft 1043 from bending. Furthermore, the shorter the length of the first telescopic component 105, the shorter the lever arm of the tensile or pushing force exerted on the template and template connector 103 due to concrete molding is relative to the first telescopic component 105. The first telescopic component 105 is less prone to deformation. In other words, under the condition of the same arrangement angle of the first telescopic component 105, the shorter the length of the first telescopic component 105, the stronger its effect of resisting the tensile or pushing force caused by concrete molding. At this time, the force borne by the second drive component 104 in the rotation axis is also smaller, thereby reducing the risk of damage to the transmission function, transmission accuracy, or even the transmission structure of the second drive component 104.

[0075] Before the second drive assembly 104 is activated, the template connector 103 can rotate freely. If its rotational direction is limited solely by, for example, a motor in the second drive assembly 104, the output shaft of the motor will bear a large torque due to the large weight of the template, both during the rotation stopping process and the rotation angle holding process. This results in significant wear and tear on the motor itself. Therefore, in some embodiments, see [reference needed]. Figure 2The drive mounting base 1042 is equipped with a torque balancing component, which is used for controlled radial clamping of the drive shaft 1043. After clamping the drive shaft 1043, the torque balancing component can limit the template connector 103 in the rotation direction. When the template connector 103 stops rotating or during the rotation angle maintenance, the clamping action of the torque balancing component can resist large torques, thereby reducing the torque pressure on the motor output shaft and thus protecting the motor.

[0076] For specific implementation, please refer to Figure 7 The torque balancing assembly may include a mounting base 1071, a first clamping guide rod 1072, a second clamping guide rod 1073, a first clamping block 1074, a second clamping block 1075, and an attraction assembly 1076. The mounting base 1071 is connected to the drive mounting base 1042, and serves as an intermediate connector to fix the torque balancing assembly relative to the drive mounting base 1042. The mounting base 1071 has clearance holes suitable for the drive shaft 1043 to pass through. The first clamping guide rod 1072 is connected to the mounting base 1071, and its length direction is perpendicular to the axis of the drive shaft 1043. The second clamping guide rod 1073 is connected to the mounting base 1071, and its length direction is perpendicular to the axis of the drive shaft 1043. The drive shaft 1043 is perpendicular to the axis. The first clamping guide rod 1072 and the second clamping guide rod 1073 are located on the radial sides of the drive shaft 1043, respectively. The first clamping block 1074 is movably sleeved on the first clamping guide rod 1072, and the first clamping block 1074 is provided with a first clamping surface suitable for clamping the drive shaft 1043. The second clamping block 1075 is movably sleeved on the second clamping guide rod 1073, and the second clamping block 1075 is provided with a second clamping surface suitable for clamping the drive shaft 1043. The attraction component 1076 is connected to the drive mounting base 1042 and is located between the first clamping block 1074 and the second clamping block 1075 to attract the first clamping block 1074 and the second clamping block 1075 to move closer to each other. The attraction component 1076 can also be configured as an electromagnet.

[0077] Furthermore, a first reset component 1077 is disposed between the mounting base 1071 and the first clamping block 1074, the first reset component 1077 being used to provide the first clamping block 1074 with a first sliding tendency away from the attraction component 1076; a second reset component 1078 is disposed between the mounting base 1071 and the second clamping block 1075, the second reset component 1078 being used to provide the second clamping block 1075 with a second sliding tendency away from the attraction component 1076; wherein, the potential energy of the first sliding tendency and the second sliding tendency are equal.

[0078] In this embodiment, when the first clamping block 1074 and the second clamping block 1075 clamp the drive shaft 1043, they do not contact each other. That is, when the first clamping surface and the second clamping surface are on the same circumference, they combine to form a non-closed circle. Specifically, refer to the clamping mode of the first clamping ring 1055 and the second clamping ring 1056 on the first telescopic cylinder 1051 mentioned above. In this embodiment, the first reset component 1077 and the second reset component 1078 are provided to ensure that the first clamping block 1074 and the second clamping block 1075 can move synchronously when they are attracted, so that they can contact the drive shaft 1043 at the same time, avoiding damage to the drive shaft 1043 due to unbalanced impact loads.

[0079] Secondly, the present invention provides a climbing formwork platform, including the multifunctional connecting device for climbing formwork as described in the first aspect.

[0080] Specifically, the climbing formwork platform also includes conventional climbing formwork components such as a mounting base, a lateral displacement assembly, and a base lifting assembly. The multi-functional connecting device for climbing formwork can be mounted on the mounting base via the lateral displacement assembly. The lateral displacement assembly moves the multi-functional connecting device closer to or further away from the point where concrete is to be poured. The mounting base is connected to the completed wall structure via the base lifting assembly to achieve overall lifting of the climbing formwork platform.

[0081] Multiple climbing formwork multi-functional connecting devices can be arranged side-by-side on several mounting bases. When constructing conventional walls, multiple climbing formwork multi-functional connecting devices can be connected together to the formwork. In this case, multiple climbing formwork multi-functional connecting devices can be raised and lowered together to adjust the height of the formwork. When constructing cement columns with different axial directions, one or more climbing formwork multi-functional connecting devices can be selected to connect the formwork individually, while other climbing formwork multi-functional connecting devices can be spaced apart from the climbing formwork multi-functional connecting devices connected to the formwork under the action of the lateral displacement component to avoid interference. In other words, when several climbing formwork multi-functional connecting devices are selected to connect the formwork separately, these climbing formwork multi-functional connecting devices are arranged at intervals.

[0082] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
