[0024] See Figure 1 and Figure 2 As shown, the rotary jack of the scaffolding provided in this embodiment includes: a connecting member 10, a support assembly 20, a jack member 30, and a rotation limiting assembly 40.

[0025] The connector 10 is used to connect the scaffold, that is, to connect the rotating top support of the scaffold with the scaffold. The support assembly 20 is installed on the connector 10, and the support assembly 20 is provided with a rotating part 21. The top support member 30 is rotatably installed on the support assembly 20 through the rotating part 21. The top support member 30 is used to support the supported part, wherein the supported part can be a template in a concrete template system, and the template in the template system can be a horizontally placed template or an inclined template. The top support member 30 connected to the support assembly 20 in a rotating manner can adjust the angle according to the setting mode of the template to adapt to the use requirements of different templates, so that the top support member 30 can fit the template tightly, so that the template is more evenly stressed, so as to improve the safety of equipment use.

The rotation limit assembly 40 is used to limit the rotation of the top support member 30 relative to the support assembly 20 within a preset angle range. Moreover, when the top support member 30 rotates to a preset position within the preset angle range relative to the support assembly 20, the top support member 30 can be positioned by the rotation limit assembly 40 so that the top support member 30 can be maintained at the preset position.

[0027] It can be understood that the preset position of the supporting member 30 is a vertical state that can adapt to a horizontally placed template, or an inclined state that can adapt to an inclined template, which can be selected according to actual needs.

[0028] Particularly, the preset position of the supporting member 30 relative to the supporting assembly 20 is a specific position within a preset angle range.

[0029] Continue to see Figure 1 and Figure 2 As shown, the support assembly 20 includes a connecting plate 22 and two support plates 23. The connecting plate 22 is connected to the connecting member 10. The two support plates 23 are arranged on the connecting plate 22 at intervals from each other. In addition, a rotating portion 21 is provided on both support plates 23. The rotation limiting assembly 40 is arranged between the two support plates 23 and the top support member 30.

[0030] In this embodiment, the rotating part 21 is a rotating shaft rotatably mounted on the two support plates 23, and the rotating shafts on the two support plates 23 are coaxial. In a preferred embodiment, the rotating shafts on the two support plates 23 are the same rotating shaft, and the top support member 30 is connected to the rotating shaft, and can be rotated relative to the support assembly 20 through the rotating shaft.

A plurality of pin holes 231 are provided on the two support plates 23 around the axis of the rotating shaft, and the plurality of pin holes 231 on the two support plates 23 correspond to each other one by one. The plurality of pin holes 231 are circumferentially distributed around the axis of the rotating shaft, and the central angle of the distribution of the plurality of pin holes 231 is a preset angle. In a preferred embodiment, the plurality of pin holes 231 on each support plate 23 are circumferentially and equally distributed around the axis of the rotating shaft. A positioning hole is provided on the top support member 30. The top support member 30 rotates relative to the support assembly 20 through the rotating shaft, and the pin shaft 41 is inserted into the corresponding pin holes 231 and the positioning hole to position the top support member 30.

[0032] As described above, the angle by which the top support member 30 can rotate relative to the support plate 23 each time is the included angle between two adjacent pin holes 231 among the plurality of pin holes 231 on each support plate 23.

[0033] In another embodiment of the present application, the rotation limiting assembly 40 includes a locking bolt and a locking nut. Arc-shaped adjustment holes are provided on the two support plates 23 around the axis of the rotating shaft. The center of the arc-shaped adjustment hole coincides with the intersection point of the axis of the rotating shaft and the support plate 23, and the central angle of the arc-shaped adjustment hole is a preset angle. A positioning hole is provided on the top support member 30. The top support member 30 rotates relative to the support assembly 20 through the rotating shaft. The locking bolt is inserted into the arc-shaped adjustment hole and the positioning hole, and the locking nut is screwed onto the locking bolt to cooperate with the support plate 23 for locking to position the top support member 30. In this way, stepless adjustment of the top support member 30 can be achieved.

[0034] One end of the top support member 30 away from the support assembly 20 is provided with a supporting portion 31, and the bottom of the supported portion can be supported through this supporting portion.

[0035] In an embodiment of the present application, the supporting portion 31 is a supporting groove 311, which can accommodate the steel pipe keel of the supported portion. For example, the steel pipe keel is a keel structure connected to the bottom of the formwork in the formwork system, which can prevent the formwork from moving.

[0036] In this embodiment, the connecting member 10 is a connecting rod 11, and the connecting rod 11 is used to be inserted into the scaffolding.

[0037] In an embodiment of the present application, the connecting rod 11 is a telescopic rod to adjust the height of this rotary jack to adapt to different usage scenarios.

[0038] In another embodiment of the present application, the rotary jack of the scaffolding provided in this embodiment further includes a height adjustment assembly, and this height adjustment assembly is used to adjust the height of the connecting member 11 relative to the scaffolding, so as to adapt to different usage scenarios.
