[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0031] The embodiment of the present invention provides a climbing formwork system, which can solve the problems of small climbing formwork construction section height and low climbing formwork construction efficiency in a climbing formwork structure.

[0032] The present application provides a climbing formwork system. The climbing formwork system of the present application is described in detail below in conjunction with the accompanying drawings. The features of the following embodiments and implementations can be combined with each other unless they conflict.

[0033] See also Figure 1 、 Figure 2 as well as Figure 4 As shown, a climbing formwork system provided by an embodiment of the present invention may include: a climbing system 1 for fixing to a cast structure 61; a frame system 2, wherein the frame system 2 is installed on the climbing system 1, and the frame system 2 includes a plurality of equal corner frames 21 and plane frames 22, and the corner frames 21 and the plane frames 22 are alternately connected to form a construction area; the corner frames 21 are connected to a corner formwork 31 for forming a building corner, and the plane frames 22 are connected to a plane formwork 32 for forming a building side, and the corner formwork 31 and the plane formwork 32 are alternately connected to form a casting space.

[0034] See also Figure 1 It can be seen that the frame system 2 is arranged above the climbing system 1, and the climbing system 1 is fixed to the cast structure 61 through embedded parts buried in the cast structure 61. When climbing formwork is required, the climbing system 1 drives the frame system 2 to move vertically to complete the climbing formwork work.

[0035] See also Figure 2 and Figure 4 As shown, the frame system 2 is formed by alternately connecting the corner frame 21 and the flat frame 22. The corner frame 21 can form the corner of the building with a single template by connecting the corner template 31. Compared with the conventional construction process of using two flat templates to form the corner, forming the building corner with the corner template 31 can avoid the leakage of mortar at the corner of the building due to the connection between the two templates, that is, the edge of the corner. In this embodiment, the corner of the building is formed by the L-shaped corner template 31, wherein the angle of the corner template 31 is equal to the designed angle of the building corner. When the building has Figure 4When there are continuous corners at the upper left corner of the section 62 to be poured, the number of corner forms 31 can be reduced by setting the corner forms 31 to the corresponding continuous corners. Two adjacent corner forms 31 are connected by a flat form 32. During construction, the corner form 31 is first installed in place, and then the appropriate flat form 32 is installed based on the corner form 31. Due to the installation of the corner form 31, the formwork gap can be adjusted from the corner edge of the section 62 to the side of the section 62 to be poured. The side area provides more operating space, which facilitates subsequent adjustment of the construction joint. This improves the construction quality of the climbing formwork construction.

[0036] Furthermore, because the corner formwork 31 is used to form the building corner, after concrete is poured, the concrete is connected to both ends of the corner formwork 31. When the frame system 2 is subjected to lateral pressure at a large segment height, the corner frame 21 can transmit a single-direction horizontal force to both sides of the segment 62 to be poured. Furthermore, the corner frame 21 and the planar frame 22 are alternately connected to form a circular construction area. When a portion of the frame system 2 is impacted by a horizontal force, the frame system 2 is entirely positioned outside the segment 62 to be poured. Compared to independently installed climbing formwork devices, the integrated structure of the frame system 2 is more stable. Due to the more stable climbing formwork system, the height of the frame system 2 can be increased, thereby increasing the construction height of each climbing formwork section, reducing the number of climbing formwork installations for the bridge tower, and thus improving construction efficiency. Currently, the segment heights of conventional climbing formwork devices are 6m / 4.5m. By using the climbing formwork system provided in this embodiment, the segment height can be increased to 9m. For buildings of the same height, the large-scale segments reduce the number of building pours, which helps shorten the construction period.

[0037] See also Figure 2 as well as Figure 4 As shown, in some optional embodiments, the planar frame 22 is connected to the corner frame 21 at opposite ends, and the connection position between the planar frame 22 and the corner frame 21 is adjustable along the length of the planar frame 22. In this embodiment, the planar frame 22 is provided with multiple mounting holes at the ends, and the connection position between the planar frame 22 and the corner frame 21 can be adjusted by selecting different mounting holes to connect to the corner frame 21. In other embodiments, the planar frame 22 can be configured as a telescopic structure, and the connection position can be adjusted by extending or contracting the planar frame 22. By adapting the planar frame 22 to the different spacings between the corner frames 21, the climbing formwork system can be adapted to the construction of buildings with different cross-sections. The climbing formwork system provided in this embodiment can be used in the construction of buildings with gradually changing cross-sections. As the cross-section increases, the spacing between adjacent corner frames 21 needs to increase accordingly. In this embodiment, the planar frame 22 can be adjusted to adapt to the changing spacing between the corner frames 21.

[0038] In some optional embodiments, the planar frame 22 is detachably connected to the corner frames 21. In this embodiment, the corner frames 21 and planar frame 22 are connected by bolts. When the climbing formwork system is being raised and the spacing between the corner frames 21 needs to be adjusted, the planar frame 22 can be removed first, the corner frames 21 can be raised to the corresponding positions, and then the planar frame 22 can be installed between the two adjacent corner frames 21. This completes the construction of the frame system 2.

[0039] See also Figure 2 as well as Figure 4 As shown, the corner frame 21 includes a first frame 211 and a second frame 212 respectively arranged at both ends thereof. The first frame 211 and the second frame 212 are arranged at an angle. One end of the corner template 31 is connected to the first frame 211, and the other end of the corner template 31 is connected to the second frame 212. The first frame 211 and the second frame 212 arranged at an angle can meet the needs of fixing the corner template 31. Figure 4 As shown, in this embodiment, the corner frame 21 is connected to the corner formwork 31 through a demoulding device 5 with a telescopic function, which can improve the demoulding efficiency of the corner formwork 31. In other embodiments, the corner frame 21 can also be directly connected to the corner formwork 31 through a steel beam structure. Figure 2 As shown, the first frame 211 mentioned in this specification is the end structure of the corner frame 21 extending in the horizontal direction. Specifically in this embodiment, please refer to Figure 2 The first frame 211 of the corner frame in the upper left corner includes a rod-shaped structure connected to the flat frame 22 above the figure, and a connecting system structure vertically connected to the rod-shaped structure. In other words, the first frame 211 in this embodiment is composed of the rod and the connecting system structure. The description of the direction of the first frame 211 in this specification refers to the extension direction of the connecting system on the horizontal plane. Figure 2 The second frame 212 of the upper left corner frame 21 refers to a whole formed by connecting the transverse rod connected to the right plane frame 22 and the connecting system vertically connected to the transverse rod.

[0040] See also Figure 2 As shown, the corner frame 21 further includes an intermediate transition frame 213, which is arranged between the first frame 211 and the second frame 212. The intermediate transition frame 213, the first frame 211 and the second frame 212 are arranged at the same height and at an angle to each other. Figure 2 As shown in the corner frame 21 in the upper right corner, an intermediate transition frame 213 is provided between the first frame 211 and the second frame 212. The intermediate transition frame 213, the first frame 211 and the second frame 212, which are angled with each other, can form more than one corner to meet the construction requirements of the special-shaped tower. Figure 2 The corner frame 21 in the upper right corner only includes a first frame 211, an intermediate transition frame 213, and a second frame 212, which are connected in sequence. The corner frame 21 can accommodate the construction of two consecutive corners. In other embodiments, if the corner frame 21 needs to accommodate the construction of more than two corners, multiple intermediate transition frames 213 at angles to each other can be installed between the first frame 211 and the second frame 212 to configure the corner frame 21 into a corresponding multi-corner structure.

[0041] See also Figure 1 as well as Figure 5 As shown, in some optional embodiments, the climbing system 1 includes a support frame 11 for fixing to the cast structure 61 and a plurality of climbing drive members 12 arranged on the top of the support frame 11. The climbing drive members 12 can be vertically extended; each corner frame 21 is connected to two climbing drive members 12, one of which is arranged at the bottom of the first frame 211 and the other is arranged at the bottom of the second frame 212. The climbing of the corner frame 21 is achieved by two sets of climbing drive members 12, avoiding the deviation of the corner frame 21 due to the lack of coordination of multiple sets of climbing drive members 12. Figure 4 As shown, the corner frame 21 is connected to the control device 7. In this embodiment, the climbing drive member 12 is cooperatively controlled by the control device 7 to ensure that the climbing drive member 12 climbs synchronously.

[0042] See also Figures 3 and 4 As shown, in some optional embodiments, a demolding device 5 with adjustable telescopic length is fixedly connected to the corner frame 21. The end of the demolding device 5, which is remote from the corner frame 21, is fixedly connected to the corner form 31. By connecting the demolding device 5 with adjustable telescopic length, the corner form 31 can be easily detached with the demolding device 5, thereby improving the demolding efficiency of the climbing formwork system. In this embodiment, a hydraulically driven demolding device 5 is used to demold the corner form 31. In other embodiments, an electric cylinder or other demolding device 5 with telescopic function can also be used to achieve rapid demolding of the corner form 31.

[0043] See also Figure 3 as well as Figure 4As shown, the corner frame 21 is connected to multiple demolding devices 5. The extensibility directions of the multiple demolding devices 5 are arranged in parallel and in the same direction as the angle bisector between the first frame 211 and the second frame 212 of the corner frame 21 to which the demolding devices 5 are connected. Multiple demolding devices 5 can enhance demolding force and prevent excessive concentration of demolding force. By arranging the extensibility directions of the demolding devices 5 in the same direction as the angle bisector between the first frame 211 and the second frame 212, when the demolding devices 5 are extended or retracted, they are driven along the angle bisector between the first frame 211 and the second frame 212, preventing the demolding devices 5 from interfering with the building structure during demolding. Furthermore, the parallel arrangement of the demolding devices 5 prevents interference between the demolding devices 5. In this embodiment, the spacing between the multiple demolding devices 5 on the same corner frame 21 is equal, achieving uniform distribution of demolding force. In this embodiment, each corner frame 21 is equipped with a corresponding control device 7. The control device 7 can control the demoulding device 5 connected to the same corner frame 21. The control device 7 can control the demoulding device 5 to extend and retract simultaneously.

[0044] See also Figure 1 as well as Figure 5 As shown, in some optional embodiments, the climbing formwork system further includes a protection system 4, which is disposed outside the frame system 2. The protection system 4 prevents foreign objects from falling during the construction process, thereby ensuring the safety of the construction process.

[0045] See also Figure 1 as well as Figure 5 As shown, in some optional embodiments, the protection system 4 includes a planar protection module 42 and a corner protection module 41. The corner protection module 41 is disposed on the outside of the corner frame 21 and connected to the corner frame 21, while the planar protection module 42 is disposed on the outside of the planar frame 22 and connected to the planar frame 22. By connecting the corner protection module 41 to the corner frame 21, when the protection system 4 is affected by wind, the corner protection module 41 can transmit the wind force to both sides of the construction building. This enhances the stability of the protection system 4. The protection system 4 surrounds the frame system 2, providing good integrity and high safety.
