[0022] The following will specifically and detailedly describe the embodiments of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model. All other examples obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0023] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in, an angle steel tower circular tower base plate for mechanized construction includes a main body 1 of the tower base plate. A number of anchor bolt holes 2 are evenly arranged in a circumferential ring on the main body 1 of the tower base plate. A shoe plate 3 for fixedly installing the angle steel tower is arranged on the plate surface of the main body 1 of the tower base plate. Stiffening plates 4 are arranged at both ends of the shoe plate 3, and all the stiffening plates 4 are fixed on the plate surface of the main body 1 of the tower base plate. Combined with Figure 1 、 Figure 2 and Figure 3As shown in the figure, the main body 1 of the tower base plate is of a circular structure. The main body 1 of the tower base plate is fixedly connected to the foundation by means of flange connection with anchor bolts passing through the anchor bolt holes 2. Specifically, a circular tower base plate for angle steel towers in mechanized construction not only reflects the structural stability, but also fully considers the installation convenience and durability for long-term use. The main body 1 of the tower base plate is made of high-strength and corrosion-resistant high-quality steel. Its circular structure not only optimizes the load-bearing performance, but also reduces the foundation excavation area and construction cost. The circular structure is completed through precise numerical control cutting and bending processes to ensure the accurate dimensions of each part, so as to improve the overall structural stability and assembly accuracy. A number of anchor bolt holes 2 are evenly distributed in a circumferential ring on the main body 1 of the tower base plate. The number, aperture and distribution spacing of them are all strictly calculated to ensure the firm connection and uniform force between the main body 1 of the tower base plate and the foundation. Each anchor bolt hole 2 is designed with a reinforcing ring or a threaded sleeve to enhance the strength and sealing performance of the bolt connection, prevent loosening and water seepage. At the same time, considering the positioning requirements during construction, some anchor bolt holes 2 are also equipped with positioning pin holes to facilitate accurate alignment and installation. The shoe plate 3, as a key component for fixedly installing the angle steel tower, has a shape matching the bottom structure of the angle steel tower and is firmly combined with the main body 1 of the tower base plate by welding or high-strength bolt connection. The shoe plate 3 evenly transfers the weight of the angle steel tower to the main body 1 of the tower base plate. The stiffening plates 4 arranged at both ends of the shoe plate 3 are made of the same material as the main body 1 of the tower base plate and are fixed on the plate surface by welding, effectively enhancing the rigidity and stability of the connection between the shoe plate 3 and the main body 1 of the tower base plate, and preventing deformation or cracking caused by long-term stress. During the installation process, the anchor bolts first pass through the anchor bolt holes 2 on the main body 1 of the tower base plate and are aligned with the bolt holes or flange plates pre-buried in the foundation. Subsequently, high-strength nuts are used to tightly connect the main body 1 of the tower base plate and the foundation to form a stable support system. The entire installation process realizes mechanized operation, improves the construction efficiency and reduces the labor intensity. This circular tower base plate for angle steel towers in mechanized construction provides a solid guarantee for the stable operation of the angle steel tower with its reasonable structural design, excellent material selection and efficient installation method. It is not only applicable to various construction projects such as power engineering, communication base stations and radio and television towers, but also can effectively cope with complex and changeable geological conditions and harsh natural environments, demonstrating excellent engineering application value.

[0024] Combined Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, the shoe plate 3 includes a first shoe plate 31 and a second shoe plate 32, and the first shoe plate 31 and the second shoe plate 32 are arranged in a cross shape on the surface of the tower foot plate main body 1. Specifically, the shoe plate 3 consists of two parts, namely the first shoe plate 31 and the second shoe plate 32. These two parts are arranged in a cross shape on the surface of the tower foot plate main body 1, which not only enhances the connection strength between the shoe plate and the tower foot plate main body, but also optimizes the mechanical transmission path. The first shoe plate 31 mainly bears the vertical and horizontal loads from one side of the angle steel tower. Its shape and size are designed according to the specific structure of the bottom of the angle steel tower to ensure a tight fit with the angle steel tower and effectively disperse and transmit the load. The first shoe plate 31 is usually made of high-strength and high-toughness steel, and its surface flatness and precision are ensured through precise processing techniques to achieve seamless butt joint with the bottom of the angle steel tower. In addition, the first shoe plate 31 is connected to the tower foot plate main body 1 by welding or high-strength bolts to ensure a firm and reliable connection that is not easily loosened. The second shoe plate 32 is arranged in a cross shape with the first shoe plate 31 to jointly form a stable support structure. It is mainly responsible for bearing the load from the other side of the angle steel tower and working together with the first shoe plate 31 to ensure that the force on the entire angle steel tower can be evenly transmitted in any direction. The design of the second shoe plate 32 also focuses on the matching with the bottom of the angle steel tower and the stability of the connection. It uses the same material and processing techniques as the first shoe plate 31 to ensure excellent performance. The cross-shaped layout makes the support of the shoe plate 3 on the tower foot plate main body 1 more stable, capable of effectively resisting forces and torques from all directions and ensuring the stable operation of the angle steel tower. By dispersing the load onto the two shoe plates 3 in two directions, the load can be transmitted more evenly, reducing the phenomenon of local stress concentration and extending the service life of the entire structure. This makes the shoe plate 3 more flexible during the installation process, capable of adapting to the bottom structures of angle steel towers with different sizes and shapes, and reducing the installation difficulty and cost. The shoe plate 3 adopts the design scheme of the cross arrangement of the first shoe plate 31 and the second shoe plate 32, which not only enhances the connection strength and stability between the angle steel tower and the tower foot plate main body, but also improves the installation flexibility and aesthetics. It is an essential component in mechanized construction.

[0025] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, a number of bolt holes 33 are provided on both the first shoe plate 31 and the second shoe plate 32, and the main material of the angle steel tower leg can be fixedly installed at the included angle between the first shoe plate 31 and the second shoe plate 32 through bolts. Specifically, a number of bolt holes 33 are provided on both the first shoe plate 31 and the second shoe plate 32. These holes are not only sufficient in quantity but also reasonable in layout to meet the installation requirements of the main materials of angle steel tower legs with different specifications and models. The number of bolt holes 33 is accurately calculated and determined according to the size, weight and stress conditions of the main materials of the angle steel tower legs to ensure that each bolt hole 33 can play its due role. At the same time, the layout of the bolt holes 33 is also carefully planned to form a stable support structure, so that the main materials of the angle steel tower legs can be evenly stressed and avoid local stress concentration. The size of each bolt hole 33 is strictly designed according to the standard to ensure the matching with the installation bolts. In addition, the processing accuracy of the bolt holes 33 is also strictly controlled to ensure the smoothness and fastening effect during the installation process. The main material of the angle steel tower leg is fixedly installed at the included angle between the first shoe plate 31 and the second shoe plate 32 through bolts. This installation method is not only simple and fast but also firm and reliable. During the installation process, first, the main material of the tower leg needs to be aligned with the bolt holes 33 on the shoe plate 3, and then high-strength bolts are used for fastening. The tightening torque of the bolts needs to be strictly controlled according to the design requirements to ensure the tightness and sealing of the connection. By installing the main material of the angle steel tower leg through bolt connection, the installation time can be greatly shortened and the construction efficiency can be improved. When maintenance or replacement of the main material of the tower leg is required, it is only necessary to loosen the bolts to carry out disassembly and replacement, which is convenient and fast.

[0026] Combined Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a number of bolt holes 33 are provided on the first shoe plate 31 or the second shoe plate 32, and the main material of the angle steel tower leg can be fixedly installed at the included angle between the first shoe plate 31 and the second shoe plate 32 through bolts. Specifically, on the first shoe plate 31 or the second shoe plate 32, a number of bolt holes 33 are arranged, and these bolt holes 33 are the key to connecting the main material of the angle steel tower leg and the tower foot plate body 1. The design of these bolt holes 33 fully considers the specifications, installation positions and stress conditions of the main material of the angle steel tower leg, ensuring the accuracy and stability of the connection. The number of bolt holes 33 is determined according to the cross-sectional size, weight distribution of the main material of the tower leg and the required mechanical properties in the design. Usually, they are evenly distributed along the edge of the shoe plate 3 or a specific path to form a stable support network. This helps to evenly disperse the load of the main material of the tower leg onto the tower foot plate body 1 and reduce local stress concentration. The spacing and arrangement of the bolt holes 33 are also carefully calculated to meet the requirements of structural mechanics. A reasonable spacing can ensure the effective transfer of the interaction force between bolts, and an orderly arrangement helps to simplify the installation process and improve the construction efficiency. When installing the main material of the angle steel tower leg, first, the bottom of the main material of the tower leg needs to be aligned with the included angle between the first shoe plate 31 and the second shoe plate 32. Then, pass the pre-prepared high-strength bolts through the reserved holes on the main material of the tower leg and the bolt holes 33 on the shoe plate 3. Install nuts at the other ends of the bolts and use a torque wrench to tighten them to the specified torque according to the design requirements. In this way, the main material of the tower leg is firmly fixed on the shoe plate 3, forming a stable support structure. Installing the main material of the angle steel tower leg by means of bolt connection has the advantages of simple installation, convenient disassembly and reliable connection. This connection method not only improves the construction efficiency but also facilitates subsequent maintenance and replacement work.

[0027] Combined Figure 1 , Figure 3 and Figure 4As shown, the first shoe plate 31 and the second shoe plate 32 have a structure that is high in the middle and gradually decreases towards both ends. Specifically, the design of the first shoe plate 31 and the second shoe plate 32 with a high middle and gradually decreasing ends not only reflects the engineer's profound understanding of mechanical principles but also significantly improves the stability and load-bearing capacity of the entire connection structure. This structure design with a high middle and gradually decreasing ends enables the shoe plate 3 to more effectively distribute the force to the main body 1 of the tower foot plate when bearing the vertical load from the main material of the angle steel tower leg. Due to the higher middle part, an arch-like structure effect is formed, enhancing the ability to resist bending and deformation, thereby improving the stability of the entire tower foot plate. As the shoe plate 3 gradually decreases from the center to both ends, its cross-sectional shape also changes, and this change helps to optimize the stress distribution. During the stress-bearing process, the stress can be transmitted along a more reasonable path, avoiding the occurrence of local stress concentration and extending the service life of the shoe plate 3 and the entire tower foot plate. Since the shoe plate 3 adopts a design with a high middle and low ends, its overall structure is more compact and sturdy. It can make more effective use of materials and improve the load-bearing capacity of the shoe plate 3. At the same time, it is also convenient to match and install with the main material of the angle steel tower leg to ensure the firmness and reliability of the connection. During installation, first, the main body 1 of the tower foot plate needs to be fixed on the foundation, and its levelness and position accuracy need to be ensured. Then, the first shoe plate 31 and the second shoe plate 32 are placed on the main body of the tower foot plate according to the design requirements and fixed by welding or bolt connection, etc. When connecting the main material of the angle steel tower leg, it is necessary to ensure that the bolt holes 33 are aligned and the tightening torque of the bolts meets the design requirements. The first shoe plate 31 and the second shoe plate 32 adopting a structure design with a high middle and gradually decreasing ends not only enhance the stability and load-bearing capacity of the entire tower foot plate but also optimize the stress distribution and improve the material utilization rate.

[0028] Combined with Figure 1 , Figure 3 and Figure 4As shown, the stiffening plate 4 has a structure with a higher middle part and gradually decreasing ends. The stiffening plate 4 is arranged in a cross shape at the end of the shoe plate 3, and the heights at the intersection of the stiffening plate 4 and the shoe plate 3 are the same. Specifically, the structural design of the stiffening plate 4 with a higher middle part and gradually decreasing ends is not only beautiful and generous, but also plays an important role in mechanical properties. When the stiffening plate 4 bears the load from the main material of the tower leg of the angle steel tower, it can more effectively disperse and transfer stress, thus protecting the entire connection structure from damage. The structural design of the stiffening plate 4 is derived from the arch structure in nature, enabling the stiffening plate 4 to form a more stable support system when subjected to pressure. The height of the middle part is designed relatively high, which can bear a greater vertical load, and the stress is effectively dispersed to the shoe plate 3 and the main body 1 of the tower base plate through the gradually decreasing ends, helping to reduce material fatigue and damage caused by stress concentration. The ends of the stiffening plate 4 and the shoe plate 3 are arranged in a cross shape, which not only enhances the connection strength between the two, but also enables the entire connection structure to maintain stability when bearing loads from all directions. The cross-shaped design is also convenient for installation and positioning, improving the construction efficiency. The heights of the stiffening plate 4 and the shoe plate 3 at the intersection are designed to be the same, ensuring a smooth transition and close fit at the connection. The same height also helps to reduce the additional stress and deformation caused by the height difference, further improving the stability and reliability of the connection structure. When processing the stiffening plate 4, high-precision numerical control cutting and bending technologies are required to ensure the accuracy of its shape and size. At the same time, necessary heat treatment or strengthening treatment should also be carried out on the plate to improve its mechanical properties and corrosion resistance. During installation, it should be ensured that the cross position of the stiffening plate 4 and the shoe plate 3 is accurate, and high-strength welding or bolt connection methods should be used to firmly fix it. In addition, necessary inspections and tests should be carried out on the connection to ensure that it meets the design requirements and has sufficient load-bearing capacity. The stiffening plate 4 adopts a structural design with a higher middle part and gradually decreasing ends, and is arranged in a cross shape at the end of the shoe plate 3 with the same height at the intersection, which not only enhances the rigidity and stability of the entire connection structure, but also optimizes the stress distribution and improves the material utilization rate.

[0029] Combined with Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the tower base plate main body 1, the shoe plate 3, and the stiffening plate 4 are all made of high-strength metal materials. Specifically, in order to ensure the stability and durability of these components under harsh environmental conditions, the tower base plate main body 1, the shoe plate 3, and the stiffening plate 4 are all made of high-strength metal materials. High-strength metal materials have excellent tensile strength, yield strength, and hardness, and can withstand the huge loads from the main members of the angle steel tower legs, ensuring the stability of the tower structure. When subjected to external forces, this material is not prone to plastic deformation or fracture, thus extending the service life of the components. The metal material is subjected to appropriate anti-corrosion treatments (such as hot-dip galvanizing, spraying anti-corrosion paint, etc.), which can effectively resist the erosion of moisture, oxygen, and chemical substances in the atmosphere, reducing structural damage caused by corrosion. This is particularly important for the tower base plate and its accessories that are exposed outdoors for a long time. High-strength metal materials have good machinability and weldability, and can meet the processing requirements of complex shapes and structures. Through precise cutting, bending, stamping and other processes, tower base plates, shoe plates, and stiffening plates that meet the design requirements can be manufactured. At the same time, these components can also be firmly connected through high-strength welding methods. The tower base plate main body 1, the shoe plate 3, and the stiffening plate 4 are made of high-strength metal materials, which not only ensure the stability and durability of these components under harsh environmental conditions, but also improve the safety and reliability of the entire tower structure.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
