[0029] Please refer to Figure 2 and​​Figure 3 and Figure 5 and Figure 6 The utility model provides a technical scheme: a hyperbolic space pier column formwork device, including straight formwork 1, wherein: four straight formwork 1's outside through connecting piece 2 enclose a four -dimensional body, every two straight formwork 1's connecting place is detachably installed with corner template 4 through detachable connecting piece 3, corner template 4 includes corner back lath 41 and corner formwork 42, corner back lath 41 is installed on straight formwork 1 through detachable connecting piece 3, corner formwork 42 is welded on corner back lath 41, the utility model adopts four straight formwork 1 to enclose four -dimensional body through connecting piece 2, and combines detachable corner template 4, and this structural design makes the assembly of formwork device more flexible and convenient, compared with traditional integral formwork, in the transportation and storage process, the structure of detachable greatly saves the space, reduces transportation cost and warehousing difficulty, simultaneously, in construction site, construction personnel can more conveniently carry out the handling and operation to each component, improves the preparation efficiency of construction early stage.

[0030] The detachable design of corner template 4, when corner template 4 appears damage or needs to adjust according to the size of different hyperbolic pier, can be quickly replaced or modified, without replacing the whole formwork device, reduce the maintenance cost and construction difficulty, improve the versatility and adaptability of formwork device, can be widely applied to the construction scene of multiple hyperbolic piers.

[0031] Specifically, in the embodiment, the connecting piece 2 is an I-beam. It should be noted that the connecting piece 2 is specified as an I-beam, which has high strength and stiffness, and can provide a stable and reliable support structure for the entire formwork device. When subjected to lateral pressure during concrete pouring, the I-beam connecting piece can effectively resist deformation, ensuring the shape and size accuracy of the formwork, thereby ensuring the forming quality of the hyperbolic pier. Compared with other connecting piece materials, the I-beam has superior mechanical properties, which can reduce quality problems such as formwork deformation and leakage caused by insufficient strength of the connecting piece, reduce the risk of rework, and improve construction efficiency and engineering quality.

[0032] Specifically, in the embodiment, the detachable connecting piece 3 is a bolt and a nut. It should be noted that the bolt and the nut are used as the detachable connecting piece 3, which has the advantages of easy and quick installation and disassembly. Construction personnel can complete the connection and disassembly operation of the corner template 4 and the straight formwork 1 using simple tools, without the need for complex professional equipment and technology. This connection method not only improves the installation efficiency of the formwork, but also enables quick disassembly and reassembly when the formwork is reused, reducing the construction cycle, and also facilitating maintenance and maintenance of the formwork, reducing long-term use costs.

[0033] Specifically, in the embodiment, the corner template 42 is a steel plate. It should be noted that the corner template 42 is made of steel plate, which has good strength and wear resistance, can withstand the impact force and friction force in the concrete pouring process, is not easy to be damaged and deformed. After multiple uses, it can still maintain good surface flatness and shape accuracy, ensuring the appearance quality and dimensional accuracy of the hyperbolic pier column. In addition, the material stability of the steel plate is high, and it is not easy to be affected by environmental factors such as humidity and corrosion, prolonging the service life of the corner template 42 and reducing the replacement frequency and cost of the template.

[0034] Specifically, in the embodiment, the corner back brace 41 is a long strip structure, and the cross-sectional shape thereof is adapted to the curve shape of the corner of the hyperbolic pier column. It should be noted that the cross-sectional shape of the corner back brace 41 is adapted to the curve shape of the corner of the hyperbolic pier column. This design can make the corner back brace 41 closely fit the corner of the pier column and provide more uniform and effective support force. During the concrete pouring process, it can better resist the lateral pressure of the concrete and prevent the corner template 4 from deforming and displacing, thereby ensuring that the corner lines of the hyperbolic pier column are smooth and the size is accurate. Compared with the traditional general back brace, this specially designed corner back brace 41 improves the overall stability and reliability of the template device, reduces the concrete surface defects caused by template deformation, and improves the construction quality.

[0035] Specifically, in the embodiment, the corner template 42 is a triangle or a polygon, one side of which is fitted with the straight template 1, and the other side is connected with the corner back brace 41. It should be noted that the corner template 42 is designed as a triangle or a polygon, one side of which is fitted with the straight template 1, and the other side is connected with the corner back brace 41. This structure can form a stable connection structure at the corner of the corner template 42, effectively transferring and dispersing stress. The design of the triangle or polygon increases the stability and carrying capacity of the corner template 42, so that it can better adapt to the complex stress condition of the corner of the hyperbolic pier column. At the same time, the close fit connection with the straight template 1 and the corner back brace 41 further enhances the integrity and sealing of the entire template device, reduces the concrete pouring process, ensures the construction quality and the appearance integrity of the pier column.

[0036] In the actual hyperbolic space pier construction scene, the implementation steps of the utility model are as follows:

[0037] First, according to the accurate design parameters of the hyperbolic pier column, the size specifications and the required number of the straight template 1 are planned in detail. For the selection of the straight template 1, the existing pile cap template in the engineering site is preferred. If it cannot meet the requirements, the building board that is easy to obtain and has reasonable cost in the market is selected, such as plywood or steel plate that meets the strength requirements, and is accurately cut and processed according to the actual size to ensure that the flatness and dimensional accuracy meet the construction standard.

[0038] Subsequently, according to the unique template characteristics of the hyperbolic pier column, the advanced numerical control machining technology or high-precision mold casting process is used to produce the corner back strip 41 and the corner template 42 of the corner. The corner back strip 41 is designed as a long strip structure, and the cross-sectional shape thereof is precisely calculated and processed to ensure perfect adaptation to the curved shape of the corner of the hyperbolic pier column, thereby minimizing the use of materials while ensuring structural stability. The corner template 42 is processed into a triangle or a polygon according to the mechanical principle and the actual connection requirement, one side of which is closely attached to the straight template 1, and the other side is seamlessly connected with the back strip, and reliable connection means are also used to achieve stable connection, so as to enhance the corner strength and stability of the entire template device.

[0039] At the construction site, the construction personnel first preliminarily assemble the processed straight templates 1 according to the predetermined splicing sequence, and use temporary support structures to make them roughly shaped. Then, the specially-made corner back strips 41 and corner templates 42 are installed one by one at the corner positions of the straight templates 1, and during the installation process, the connection method designed in advance is strictly followed. For the bolt-connected parts, bolts meeting the strength requirements are used, and appropriate nuts and washers are used, and the bolts are tightened to the specified torque value by a torque wrench to ensure the tightness and reliability of the connection; for the welding parts, a professional welder operates according to the standard welding process to ensure the quality and strength of the weld and prevent defects such as virtual welding and missed welding. After the installation of the corner back strips 41 and the corner templates 42 is completed, the entire template device is comprehensively checked and adjusted to ensure that the components are firmly connected, the template surface is flat, and the size meets the design requirements, thereby forming a complete, stable and accurate hyperbolic spatial pier column template device, providing a solid foundation guarantee for subsequent concrete pouring and other construction procedures, and ensuring the smooth progress of the construction process and the high standard of the engineering quality.

[0040] The beneficial effects of the utility model are as follows: the utility model does not need to build a complete set of steel templates, but only needs to produce the back strip and the corner template of the corner according to the template characteristics of the hyperbolic pier column, thereby greatly reducing the construction cost. Compared with the prior art, the high cost of customizing a complete set of complex steel templates is avoided, and the material cost is significantly reduced.
