For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0034] Please refer to the attached Figure 1 To Attachment Figure 8 The utility model describes an external hanging type climbing and flipping combined formwork system.

[0035] Currently, the more common hollow thin-walled pier construction formworks are: the first is to use a flip mold system for construction. This formwork system mainly integrates the formwork and the operating platform. After the bottom section is removed, it is flipped to the upper section for installation. The formwork system is mainly fixed to the pier column with tension bolts. The installation and removal of the formwork involves the lifting of large components, and workers are required to pry the formwork. The safety risk is high and it has been gradually eliminated; the second is to use a sliding formwork system for construction. This formwork system must require the steel bar binding and rigid frame construction to be completed within the specified time before each sliding, and the appearance quality effect is not ideal; the third is to use a traditional hydraulic climbing formwork system. Although it has a high degree of intelligence and good safety, the traditional hydraulic climbing formwork system is more expensive than other molds, mainly because the required hydraulic equipment is large in number and expensive, and the subsequent maintenance cost is high.

[0036] This formwork system includes an operating platform 2 and a climbing component 3. The climbing component 3 is connected to the operating platform 2 to drive the operating platform 2 to climb. A shaping template 4 is connected to the operating platform 2. When the climbing component 3 drives the operating platform 2 to climb, the shaping template 4 can slide relative to the operating platform 2 to adjust the distance between the shaping template 4 and the pier 1, and when the casting section of the pier 1 changes, the pier 1 with an inclination can be cast.

[0037] A template hanger 5 is fixedly connected to the operating platform 2, and a slide groove is provided on the template hanger 5. A sliding rod 54 is slidably connected to the slide groove, and the sliding rod 54 is connected to the shaping template 4. A rotating rod 53 is rotatably connected to the sliding rod 54, and a moving wheel 52 is fixedly connected to the rotating rod 53. The moving wheel 52 is rollingly connected to the template hanger 5. The shaping template 4 can slide relative to the template hanger 5 by setting the shaping template 4, so that the distance between the shaping template 4 and the pier 1 can be adjusted; by setting the moving wheel 52, the effect of facilitating the movement of the shaping template 4 is achieved.

[0038] Specifically, a tensioner 6 is connected to the sliding rod 54 , and one end of the tensioner 6 away from the sliding rod 54 is connected to the shaping template 4 , so that the up and down movement of the shaping template 4 can be adjusted by the tensioner 6 .

[0039] Specifically, an external frame protection steel plate mesh is installed on the outside of the operating platform 2 to form an outer protection system of the template system.

[0041] When the latching teeth 56 are in the engaged state, the latching teeth 56 are engaged with the latching strip 51, so that the moving wheel 52 is stationary, so that the molding template 4 cannot move relative to the template hanger 5, and at this time, the hand push rod 55 is in a free state, and the hand push rod 55 is in contact with the template hanger 5;

[0042] When the latching tooth 56 is in the separated state, the push rod 55 is manually lifted to make the push rod 55 rotate around the rotating rod 53. Since the push rod 55 is fixedly connected to the latching tooth 56, the latching tooth 56 also rotates around the rotating rod 53, so that the latching tooth 56 cancels the engagement with the clamping strip 51, and the moving wheel 52 can roll relative to the formwork hanger 5. In addition, the push rod 55 can be manually pushed forward or backward to make the moving wheel 52 slide forward or backward relative to the formwork hanger 5 to change the distance between the forming formwork 4 and the pier 1.

[0043] The rotating rod 53 is rotatably connected to a limiter 57, which can limit the moving wheel 52. The template hanger 5 is provided with a slide groove, and the template hanger 5 is slidably connected with the limiter 57 through the slide groove. The limiter 57 is provided with an inclined surface, and the limiter 57 cooperates with the latch 56 through the inclined surface. The limiter 57 has a limited state and a released state.

[0044] When the stopper 57 is in the limiting state, the latching teeth 56 abut against the inclined surface of the stopper 57, so that the stopper 57 slides toward the moving wheel 52, so that the stopper 57 contacts the moving wheel 52, limiting the moving wheel 52, and thus the molding template 4 cannot move relative to the template hanger 5, and at this time, the hand push rod 55 is in a free state, and the hand push rod 55 contacts the template hanger 5;

[0045] When the limit switch 57 is in the released state, the push rod 55 is manually lifted to make the push rod 55 rotate around the rotating rod 53 as the center. Since the push rod 55 is fixedly connected to the latch tooth 56, the latch tooth 56 also rotates around the rotating rod 53 as the center. The latch tooth 56 is separated from the inclined surface of the limit switch 57, so that the limit switch 57 is reset and the contact with the moving wheel 52 is cancelled, and the moving wheel 52 can roll relative to the formwork hanger 5. Then, the push rod 55 can be manually pushed forward or backward to make the moving wheel 52 slide forward or backward relative to the formwork hanger 5 to change the distance between the forming formwork 4 and the pier 1.

[0048] Preferably, sleeves 23 and trusses 22 are provided at the two inclined side ends of the pier 1, and the trusses 22 and the sleeves 23 can slide relative to each other. Non-sliding trusses 22 are provided at the two vertical side ends of the pier 1, so that only the trusses 22 at the two inclined side ends of the pier 1 can slide. In other embodiments of the utility model, trusses 22 and sleeves 23 can also be provided at the four side ends of the pier 1, so that the trusses 22 at the four side ends of the pier 1 can slide.

[0049] When the four side ends of the pier column 1 are inclined, trusses 22 and sleeves 23 can be provided at the four side ends of the pier column 1, so that the trusses 22 at the four side ends of the pier column 1 can slide.

[0050] A threaded sleeve is fixedly connected to the sleeve 23, and a threaded rod 21 is screwed on the threaded sleeve. One end of the threaded rod 21 is rotatably connected to the truss 22, and the end of the threaded rod 21 away from the truss 22 is fixedly connected to a hand-turned frame; by rotating the hand-turned frame, the threaded rod 21 is rotated synchronously, and since the threaded rod 21 is screwed to the threaded sleeve, the threaded rod 21 can slide relatively while rotating, and since the threaded rod 21 is rotatably connected to the truss 22, and the truss 22 is limited by the sleeve 23, the truss 22 slides following the threaded rod 21 without rotating, so that the distance between the truss 22 and the pier 1 can be adjusted.

[0054] The second formwork 42 includes a plurality of single formworks 43. The single formwork 43 connected to the first formwork 41 is split along an oblique line into a first inclined plate 44 and a second inclined plate 45. When the casting section of the pier 1 is inclined, the first inclined plate 44 is removed to connect the first formwork 41 to the second inclined plate 45, so that the casting section of the pier 1 is inclined. Subsequently, when casting upward, the single formwork 43 adjacent to the second inclined plate 45 is removed, and the second inclined plate 45 is moved to the position of the single formwork 43, so that the casting section of the pier 1 has an inclination.
