Description

Technical Field

[0001] This invention belongs to the field of bridge engineering construction technology, and in particular relates to a tower building machine and construction method suitable for the construction of spatial irregular tower columns. Background Technology

[0002] Currently, irregularly shaped tower columns are becoming increasingly common. Traditional main tower construction often employs climbing formwork, but this method is not suitable for irregularly shaped tower columns. Firstly, if the climbing formwork system is poorly designed, coupled with the complex curvature of the irregularly shaped tower column, the climbing formwork structure needs repeated adjustments based on the curvature changes of each segment during construction. This results in low construction efficiency, extended construction period, high construction costs, and high construction safety risks. Secondly, due to the curved surfaces of the irregularly shaped tower column, the climbing formwork does not fit tightly to the changing shape of the tower segment, failing to accurately represent the segment's shape. This negatively impacts the spatial alignment of the tower segment and the quality of concrete pouring. Thirdly, the hydraulic climbing formwork system only forms a unified structure around the tower column, but the top parts are not interconnected, leading to overall instability and potential safety hazards. Finally, traditional climbing formwork construction requires a large amount of equipment, is cumbersome to install, and is complex and costly. Therefore, it is necessary to make improvements and provide a new technical means to solve the above problems. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and propose a tower building machine and construction method suitable for the construction of irregularly shaped tower columns in space.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

Several inner guide wheels are provided on the outer edge of the inner mold suspension platform, and the outer mold suspension platform is connected to the outer suspension locks.

An outer guide wheel is provided at the end supported on the tower column segment. One end of the adjustment rod is connected to the outer formwork suspension platform, and the other end is connected to the outer template. An outer template suspension lock is also provided at the bottom of the top operating platform. The upper end of the outer template is connected to the outer template suspension lock. The top operating platform is connected to the lifting frames on both sides through angle adjustment devices.

[0009] Furthermore, the lifting device includes a base on which a lifting cylinder is mounted. The extended rod end of the lifting cylinder faces upward, and a lifting frame is connected to the end of the extended rod.

[0010] Furthermore, the lifting frame is equipped with a jacking block, and the extended rod end of the lifting cylinder is hinged to the jacking block.

[0011] Furthermore, the two ends of the adjusting rod are hinged to the outer mold suspension platform and the outer template, respectively.

[0012] Furthermore, several connecting columns are provided on the side of the inner template that is different from the working surface, and on the side of the outer template that is different from the working surface.

[0015] S2. Arrange the stiffening frame and concrete reinforcement mesh for the next tower column casting segment;

[0016] S3. After the concrete of the cast tower column segment reaches the design strength, separate the inner and outer formwork from the tower column, lift it with the jacking device, and let the suspension support device pull the formwork up.

[0017] S4. Adjust the guiding adjustment device and the suspension support device according to the current trend of the curved line of the tower column segment so that the formwork meets the current construction requirements;

[0018] S5. Pour concrete into the main formwork, repeat this process, and the four limbs of the tower column are completed.

[0019] S6. After the four limbs of the tower column are joined together, the tower building machine is assembled on the joined tower column segment.

[0020] S7. Repeat steps 1-5 until the entire irregular-shaped tower column is finally poured.

The higher degree of connection between the components results in better overall stability. Therefore, this tower-building machine enhances construction safety, improves construction quality and progress, and reduces construction costs to some extent. Attached Figure Description
