[0002] With the continuous emergence of high-rise buildings in China, more and more architectural designs adopt cantilevered floors and roofs. The concrete structure cantilevers outward on the roof or at a certain height to achieve a unique facade effect in the architectural design and increase more usable space.

[0003] In the prior art, during the construction of the inclined columns of the cantilever structure, a supporting formwork needs to be built. After the steel cage of the inclined column is tied and fixed, a formwork is set up on the outside of the steel cage to form a pouring space surrounding the steel cage, and a support frame is built on the outside of the formwork. The support frame provides an operating platform for the construction personnel and provides a certain support for the formwork, so that the operators can pour concrete into the pouring space. However, the supporting capacity of such a support frame for the formwork is limited. Since the steel cage and the formwork are prone to deformation and deflection under inclination and self-weight, especially during the subsequent concrete pouring, the pressure from the concrete on the formwork exacerbates this phenomenon, thereby reducing the molding quality of the inclined column, so further improvement is needed.

[0019] Optionally, when the pull rod is displaced, the rotation directions of the rotating disk and the driving disk are opposite; a plurality of one-way anti-rotation grooves are provided on the surface of the rotating disk close to the driving disk and a plurality of one-way anti-rotation grooves are arranged at intervals around the central axis of the rotating disk, and the mounting bracket is provided with a mounting groove located between the rotating disk and the driving disk; the limiting member includes a limiting column and a torsion spring, the limiting column is rotatably connected in the mounting groove, the torsion spring is arranged between the limiting column and the inner wall of the mounting groove, the torsion spring normally causes one end of the limiting column to rotate out of the mounting groove and embed into the one-way anti-rotation groove of the driving disk, and the other end of the limiting column rotates out of the mounting groove and embeds into the one-way anti-rotation groove of the rotating disk; when the pull rod is displaced toward the mounting bracket, the inner wall of the one-way anti-rotation groove pushes the limiting column to rotate into the mounting groove, and when the pull rod is displaced away from the mounting bracket, the two ends of the limiting column respectively limit the driving disk and the rotating disk in direction.

[0023] Optionally, a limiting slide is provided on the sliding surface of the connecting plate, and a through groove is opened on the surface of the limiting slide for the vertical rod and the second docking column to pass through. When the tension rod is in a tensioned state, the second docking column drives the limiting slide to slide and makes the inner wall of the through groove press against the outer wall of the vertical rod.

[0024] By adopting the above-mentioned technical solution, through the setting of the limiting slide, by driving the rotating disk to rotate, the pull rod is forced to move toward the side close to the installation bracket, and the pull rod pulls the connecting disk through the second docking column, so that the multiple connecting disks in the installation area can be in a tensioned state; in this process, the second docking column can push the limiting slide, so that the inner wall of the through groove of the limiting slide is pressed against the outer peripheral wall of the vertical rod, thereby improving the connection stability between the vertical rod and the connecting disk, and then improving the structural strength of the support frame.

After the cross bar is tightened, the rotating disk is limited by the limiting member, which greatly improves the structural stability of the support frame; 3. Through the setting of the limit column and the torsion spring, under the action of the torsion spring, one end of the limit column is embedded in the one-way anti-rotation groove of the driving disk, and the other end is embedded in the one-way anti-rotation groove of the rotating disk; the effect that can be achieved at this time is that when the pull rod is driven to move toward the side close to the mounting bracket, both the driving disk and the rotating disk can rotate (that is, the rotating disk can be driven to rotate by the driving disk to drive the pull rod to move toward the side close to the mounting bracket); when the reaction force of the connecting disk drives the pull rod to move toward the side away from the mounting bracket, the driving disk and the rotating disk are limited to each other under the action of the limit column and cannot rotate, thereby realizing the one-way displacement of the pull rod, reducing the possibility of free rotation of the driving disk and the rotating disk under the action of the reaction force of the connecting disk, and then the multiple connecting disks in the installation area can always remain in a taut state, which greatly improves the operational convenience of the overall structure.

[0046] The implementation principle of Example 2 of the present application is as follows: after a plurality of vertical rods 21 and a plurality of horizontal rods 22 are spliced ​​together to form a support frame 2, the mounting bracket 51 is placed at the center of the mounting area 23, and the end of the tie rod 52 away from the mounting bracket 51 is connected to the corresponding connecting disk 31, and then the driving member is used to drive the rotating disk 53 to rotate, and the rotating disk 53 can push the first docking column 521 through the inner wall of the guide groove 531, driving the tie rod 52 to move toward the side close to the mounting bracket 51; the plurality of tie rods 52 simultaneously pull their respective corresponding connecting disks 31, thereby forcing the connecting seats at the four corners of the mounting area 23 to move toward the center of the mounting area 23 to tighten the horizontal rod 22. After the horizontal rod 22 is tightened, the rotating disk 53 is limited by the limiting member, which greatly improves the structural stability of the support frame 2, thereby improving the supporting effect of the formwork 1 and the safety of subsequent concrete pouring construction.

[0047] Embodiment 3: The embodiment of the present application discloses a cantilever structure supporting formwork.

[0048] Reference Fig. 9 , Fig.10 The difference between the cantilever structure supporting formwork disclosed in the embodiment of the present application and embodiment 2 is that: It should be noted that, in the present embodiment, when the pull rod 52 is displaced, the rotation directions of the rotating disk 53 and the driving disk 54 are opposite, and a plurality of one-way anti-rotation grooves 532 are provided on the surface of the rotating disk 53 close to the driving disk 54 and on the surface of the driving disk 54 close to the rotating disk 53. The plurality of one-way anti-rotation grooves 532 are arranged at intervals around the central axis of the rotating disk 53.

[0049] The mounting bracket 51 is provided with a plurality of mounting grooves 512 located between the rotating disk 53 and the driving disk 54, and the number of the limiting members is arranged corresponding to the number of the mounting grooves 512; the limiting members include a limiting column 57 and a torsion spring, the limiting column 57 is rotatably connected in the mounting groove 512, one end of the torsion spring (not shown in the figure) is fixedly connected to the limiting column 57, and the other end is fixedly connected to the inner wall of the mounting groove 512, and the torsion spring normally causes one end of the limiting column 57 to rotate out of the mounting groove 512 and embed into the one-way anti-rotation groove 532 of the driving disk 54, and the other end of the limiting column 57 rotates out of the mounting groove 512 and embeds into the one-way anti-rotation groove 532 of the rotating disk 53.

[0050] When the tie rod 52 moves toward the mounting bracket 51, the inner wall of the one-way anti-rotation groove 532 pushes the limit column 57 to rotate into the mounting groove 512. When the tie rod 52 moves away from the mounting bracket 51, the two ends of the limit column 57 respectively limit the driving disk 54 and the rotating disk 53.

[0051] Reference Fig. 9 , Fig.10 The limiting column 57 is fixedly connected to the rotating column 571, one end of the rotating column 571 is fixedly connected to the side wall of the limiting column 57, and the other end passes through the mounting groove 512 and is fixedly installed with a second force rod 572. The second force rod 572 is used to drive the two ends of the limiting column 57 to rotate into the mounting groove 512 to simultaneously unlock the driving disk 54 and the rotating disk 53, so that the driving disk 54 and the rotating disk 53 can rotate freely.

[0052] The implementation principle of Example 3 of the present application is as follows: under the action of the torsion spring, one end of the limit column 57 is embedded in the one-way anti-rotation groove 532 of the driving disk 54, and the other end is embedded in the one-way anti-rotation groove 532 of the rotating disk 53; the effect that can be achieved at this time is that when the pull rod 52 is driven to move toward the side close to the mounting bracket 51, both the driving disk 54 and the rotating disk 53 can rotate (that is, the rotating disk 53 can be driven to rotate by the driving disk 54 to drive the pull rod 52 to move toward the side close to the mounting bracket 51), thereby The connecting disk 31 is tightened; when the reaction force of the connecting disk 31 drives the pull rod 52 to move toward the side away from the mounting bracket 51, the driving disk 54 and the rotating disk 53 are limited to each other by the limiting column 57 and cannot rotate, thereby realizing unidirectional displacement of the pull rod 52 and reducing the possibility of free rotation of the driving disk 54 and the rotating disk 53 under the reaction force of the connecting disk 31, so that the multiple connecting disks 31 in the installation area 23 can always remain in a tightened state, greatly improving the operational convenience of the overall structure.

[0053] Embodiment 4: The embodiment of the present application discloses a cantilever structure supporting formwork.

[0054] Reference Fig.11 The difference between the cantilever structure supporting formwork disclosed in the embodiment of the present application and the embodiment 3 is that: The locking cam 33 is provided to the locking cam 35 so as to lock the locking cam 35. The locking cam 35 is provided with a locking cam 35a on the locking cam 35b, and the locking cam 35b is provided with a locking cam 35c. The locking cam 35a is provided to lock the locking cam 35b on the locking cam 35b.

[0055] Reference Fig.12 In this embodiment, a limiting slide bar 34 is slidingly arranged on the surface of the connecting plate 31, and a through groove 341 is opened on the surface of the limiting slide bar. The through groove 341 is used for the vertical rod 21 and the second docking column 522 to pass through. When the tension rod 52 is in a tensioned state, the second docking column 522 drives the limiting slide bar 34 to slide and makes the inner wall of the through groove 341 press against the outer peripheral wall of the vertical rod 21.

[0056] The implementation principle of Example 4 of the present application is as follows: by driving the rotating disk 53 to rotate, forcing the pull rod 52 to move toward the side close to the mounting bracket 51, the pull rod 52 pulls the limiting slide 34 through the second docking column 522, so that the inner wall of the through groove 341 of the limiting slide 34 is pressed against the outer peripheral wall of the vertical rod 21. At the same time, the second docking column 522 can push the pressing rod 35 to press against the side wall of the limiting insert 33, thereby achieving the effect that when the pull rod 52 is in a tightened state, the vertical rod 21 and the horizontal rod 22 can be further limited at the same time, which greatly improves the connection stability between the vertical rod 21 and the connecting disk 31, and the horizontal rod 22 and the connecting disk 31, thereby improving the structural strength of the support frame 2.

[0057] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
