At present, the buckle type scaffolding is widely used in construction projects. It has the advantages of high safety, good deformation resistance, high stability and load-bearing capacity, and easy assembly and disassembly. However, it also has corresponding disadvantages. Due to the limitations of product model and size, it is less flexible than steel pipe scaffolding, and some special locations often require the use of a combination of different types of scaffolding.

[0003] The current specifications of the disc-type scaffolding mainly include 0.5m vertical pole, 1m vertical pole, 1.5m vertical pole, 2m vertical pole, 2.5m vertical pole, 3m vertical pole, 0.2m base, 0.35m base, 0.3m cross bar, 0.6m cross bar, 0.9m cross bar, 1.2m cross bar, 1.5m cross bar, 0.6*1.5 diagonal bar, 0.9*1.5 diagonal bar, 1.2*1.5 diagonal bar, 1.5*1.5 diagonal bar, adjustable supports, adjustable supports, etc., adjustable supports and supports; in the current construction, most projects will be designed with basement ramps and stairs. Due to the slope and inclination, the horizontal universal adjustable support is difficult to meet the construction requirements. Therefore, most projects will use the top support for the bottom support, and use wooden formwork or other materials to fill the gap at the slope foot until it is horizontal and stable to meet the formwork requirements.

[0004] The existing method uses soft materials for filling and is not a matching structure with the frame, so there are corresponding dangerous factors such as looseness and slippage. Severe cases may cause the formwork frame to collapse, posing a certain safety risk. Therefore, it is necessary to develop a disc-type rotatable base support. Utility Model Content

[0005] In response to the deficiencies in the prior art, the utility model develops a disc-type rotatable base support bracket, which can effectively solve the problem that the supports in the existing formwork system cannot rotate and cannot meet the formwork needs of construction under slope or inclination conditions, thus requiring additional pads. While improving construction efficiency, it also improves the safety of the support system.

[0031] like Figure 1 、 Figure 2 and Figure 4 As shown, the support uprights 2 are threaded rods, which can be easily connected to the scaffolding body and adjusted in length.

[0033] like Figure 4 and Figure 5 As shown, limit blocks are provided at both ends of the slide 4 in the longitudinal direction.

[0034] like Figure 4 and Figure 5 As shown, the length of the slide seat 4 is equal to the distance between two adjacent limiting holes 22.

[0035] like Figure 1 and Figure 4 As shown, the lengths of the connecting rods 6 in the two positioning assemblies are not equal and the length difference is not less than the distance between the two third rotating seats 7; the connecting rod 6 can also be a telescopic rod, which is more convenient when it is inconvenient to store.

[0036] like Figure 3 and Figure 4 As shown, the support 1 is provided with supports 101 symmetrically on both sides of the length direction of the first rotating base 21 at one end away from the supporting pole 2 , and the supports 101 are provided with reserved holes 102 in an array.

[0037] Principle and operation process

[0038] This utility model features symmetrical supports 101 at the end of the support 1 facing away from the support upright 2, along the length of the first rotating seat 21. Pre-set holes 102 are arranged in an array on the supports 101. After positioning, these pre-set holes 102 can be used for anchoring. This anchoring method effectively enhances the stability of the entire device after fixation, distributing the forces, and ensuring stability when subjected to various external forces (such as vibration and loads during construction). Once the support 1 is rotated to the desired angle, the semicircular sleeve 3 engages the retaining hole 22 on the support upright 2 via a stop bolt 31 to secure the device. The semicircular sleeve 3 can rotate about the second rotating seat 5. A connecting rod 6 connects the semicircular sleeve 3 to the third rotating seat 7 on the support 1. This facilitates installation when adjusting the angle of the support 1. The operator can easily rotate the support 1 to the desired angle and then secure it by tightening the stop bolt 31, significantly improving operational convenience. The two semicircular sleeves 3 are staggered and utilize connecting rods 6 of unequal lengths. This design optimizes force distribution and improves support stability. The unequal lengths of the connecting rods 6 create an asymmetrical, stable structure that better resists deformation when the device is subjected to external forces. Furthermore, the difference in length between the connecting rods 6 is set to be no less than the spacing between the two third rotating seats 7. This ensures that the two semicircular sleeves 3 do not collide when the support 1 rotates, further ensuring the stability of the entire support structure during dynamic adjustment. A slide 4 is provided, and its length is equal to the spacing between two adjacent limiting holes 22. The semicircular sleeves 3 are slidably connected to the slide 4 via a slider 32. If no corresponding limiting hole 22 is found after angle adjustment, the slider 32 can slide within the slide 4, thereby fine-tuning the position of the semicircular sleeve 3 so that the limiting bolt 31 can align with the appropriate limiting hole 22. Limit blocks are provided at both ends of the slide 4 in the longitudinal direction to prevent the slider 32 from falling out of the range of the slide 4 during sliding, ensuring the reliability of the fine-tuning function and the normal operation of the entire device. After the symmetrically arranged positioning components are fixed, one provides support force for one side of the support 1, and the other provides tension for the other side of the support 1. This symmetrical force mode can effectively balance the forces on the support 1 in all directions, avoid instability caused by excessive force on one side, and thus improve the stability of the device after fixation. The utility model adopts a rotatable support 1, which effectively solves the problem that the support 1 in the existing formwork system cannot meet the construction requirements and needs to be padded. When encountering problems such as angle mismatch, the traditional support 1 needs to add gaskets to adjust, which is not only cumbersome to operate but also may affect the stability of the support system. The rotatable support 1 can easily adapt to different construction angle requirements through its own rotation and positioning functions, thereby improving construction efficiency. At the same time, it also improves the safety of the support system by reducing the unstable factors that may be caused by adding pads.

[0039] During use, first connect the support post 2 to the scaffolding system. Then, manually rotate the support 1 according to the construction requirements so that the support 1 rotates around the first rotating seat 21 to the appropriate angle. During the rotation process, pay attention to the position of the two semicircular sleeves 3 to ensure that they do not collide with each other. When the support 1 is rotated to the appropriate angle, screw the limit bolts 31 on the semicircular sleeves 3 into the corresponding limit holes 22 on the support post 2 to secure the semicircular sleeves 3 to the support post 2. If no corresponding limit holes 22 are found after the angle adjustment, the position of the semicircular sleeves 3 can be fine-tuned within the slide 4 by sliding the slider 32. Since the length of the slide 4 is equal to the distance between two adjacent limit holes 22, the limit bolts 31 can be easily aligned with the appropriate limit holes 22 before being secured. Subsequently, the anchoring operation is performed using the reserved holes 102 of the support 101 on the support 1. A suitable anchor is passed through the reserved holes 102 and secured to the corresponding foundation structure to enhance the stability of the entire device.

On the basis of the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
