DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1-Figure 5As shown, the present invention provides: an assembled special-shaped plain concrete formwork, comprising an outer formwork 1 and an inner formwork 2, a cavity for concrete filling is formed between the outer formwork 1 and the inner formwork 2, and the concrete is directly poured into the cavity; the outer formwork 1 and the inner formwork 2 use high-strength, corrosion-resistant high-quality steel as the base material, and the surface is covered with a layer of specially treated wear-resistant, easy-to-demold plain concrete special membrane material. This design not only ensures the durability of the overall formwork, but also facilitates the smooth demolding of the concrete, ensuring the surface finish and aesthetics of the finished concrete wall. The mounting member 4 is arranged on the outer surface of the outer formwork 1 and the inner formwork 2, and a reinforcing tube 7 for reinforcing the outer formwork 1 or the inner formwork 2 is also installed between the mounting member 4. The reinforcing tube 7 is made of lightweight and high-strength aluminum alloy or carbon fiber material, which not only reduces the overall weight, but also improves the bearing capacity and stability of the overall formwork system. The outer surface of the outer template 1 or the inner template 2 is provided with a slide rail 5, a sliding member 6 is fixed on the mounting member 4, and the sliding member 6 is slidably arranged on the slide rail 5, and a second threaded rod 9 is also arranged between the sliding members 6, the mounting member 4 includes a clamping member 41 and a first threaded rod 42, the first threaded rod 42 is movably arranged in the mounting member 4, the clamping member 41 is movably arranged on the mounting member 4 through an axis, one end of the clamping member 41 is movably provided with a threaded sleeve through the axis, and the threaded sleeve is movably connected to the first threaded rod 42 through a thread, one end of the first threaded rod 42 passes through the mounting member 4 and is connected with a rotating member 43, when the rotating member 43 rotates, the first threaded rod 42 is driven to rotate, and the first threaded rod 42 moves the clamping member 41 to clamp the reinforcing tube 7, the clamping member 41 is made of elastic material, such as spring steel or polymer composite material, has certain elasticity and clamping force, can fit closely to the reinforcing tube 7 to adjust the position between the mounting members 4, and the second threaded rod 9 on the bottommost mounting member 4 is screwed into the slide rail 5; refer to Figure 8As shown, in order to facilitate the installation of the scaffolding on the outer formwork 1 and the inner formwork 2, a scaffolding fixture 44 is also slidably arranged on the slide rail 5. The scaffolding fixture 44 is designed as a slider that matches the slide rail 5 to ensure that it can slide smoothly on the slide rail 5. Its main body is made of high-strength aluminum alloy or steel, and the surface is treated with anti-corrosion to increase durability and corrosion resistance. The scaffolding fixture 44 is fixedly connected to the mounting member 4 through a second threaded rod 9. There is a hole reserved for the installation of the second threaded rod 9 on the scaffolding fixture 44 (not shown in the figure). This method allows the staff to adjust the position of the scaffolding fixture 44 according to actual needs during the installation process to ensure the stability and safety of the scaffolding. A first clamp 45 is fixed on one side of the scaffolding fixture 44, and the first clamp 45 is fixed on one side of the scaffolding fixture 44 as the main component for connecting the scaffolding. It is designed with holes matching the diameter of the scaffolding pipe so as to firmly clamp the scaffolding rods. In order to adapt to scaffolding rods of different diameters, the first clamp 45 can be designed as a style with an adjustable clamping mechanism, such as a spiral clamping ring or a spring locking device, to ensure that a stable connection can be achieved under various working conditions. Two second clamps 46 and a third clamp 47 are welded on the first clamp 45 to provide more support points and stability for the scaffolding. These clamps are also designed with holes matching the scaffolding rods, which can significantly enhance the connection strength between the scaffolding and the formwork system to prevent displacement or overturning during the concrete pouring process. The first clamp 45, the second clamp 46 and the third clamp 47 can be inserted into the scaffolding, and each scaffolding is connected by a clamp, and each scaffolding rod is connected by a standard clamp. The clamp is designed to be easy to install and disassemble to ensure the flexibility and efficiency of the construction process. At the same time, the clamp should have good bearing capacity and anti-deformation ability to ensure the overall stability of the scaffolding.

[0033] The design of the scaffolding fixture 44 and its matching first clamp 45, second clamp 46 and third clamp 47 provides great convenience and safety for the installation of the outer formwork 1 and the inner formwork 2. Through the effective combination and application of these design elements, it can be ensured that the scaffolding system stably and reliably supports the formwork system and successfully completes the concrete pouring operation.

[0034] Support member 8, between which adjusting member 81 is arranged, and adjusting member 81 is used to fix support member 8, support member 8 is an important structural component in the assembled special-shaped plain concrete formwork system, which is arranged between outer formwork 1 and inner formwork 2 or other key positions of formwork system to provide additional support force, so as to ensure that the formwork maintains a stable shape and position during concrete pouring. Support member 8 is usually made of high-strength, corrosion-resistant steel or aluminum alloy material to withstand the huge pressure from concrete. Adjusting member 81 can be fixed by screw and nut, screw passes through the reserved hole on support member 8, and fixes support member 8 by tightening nut. This design is simple and effective, easy to install and adjust. The staff can change the tightening degree of screw by rotating nut, so as to achieve fine adjustment of the position of support member 8. And adjusting member 81 can also be adjusted by telescopic screw and sleeve combination, which allows screw to be freely extended and retracted in sleeve, and staff can adjust the extension length of screw as needed, and fix it in the desired position by locking mechanism. This design not only facilitates the installation and adjustment process, but also improves the adaptability and stability of the formwork system.

[0035] refer to Figure 1 and Figure 2 As shown, several outer formworks 1 can be spliced ​​up and down and on both sides, and several inner formworks 2 can be spliced ​​up and down and on both sides. Both the outer formworks 1 and the inner formworks 2 are designed as modular units that can be spliced ​​up and down and on both sides. This design enables the formwork system to flexibly adapt to concrete structures of different sizes and shapes without the need to customize unique formworks for each structure. A splicing structure is formed at the splicing of multiple outer formworks 1 or multiple inner formworks 2. A quick-connect connector 3 is provided on the outer surface around the outer formworks 1 and the inner formworks 2. The quick-connect connector 3 includes a connector male buckle 31 and a connector female buckle 32. The connector male buckle 31 and the connector female buckle 32 are spliced ​​with each other to splice and fix multiple outer formworks 1 or multiple inner formworks 2 into a whole. When the formwork is assembled, the connector male buckle 31 and the connector female buckle 32 are coupled to achieve quick splicing. When the formwork is to be separated, the connector male buckle 31 and the connector female buckle 32 are disengaged to achieve quick disassembly.

[0036] During the template assembly process, the staff only needs to align the connector male buckle 31 with the connector female buckle 32 and apply appropriate force to achieve the rapid coupling of the two. This operation is simple and fast, without the need for complex tools or additional fixings. This structure greatly shortens the assembly and disassembly time of the template and improves the construction efficiency. The modular design and quick splicing mechanism enable the template system to easily adapt to various complex construction environments and structural shapes. Since the template can be quickly disassembled and reassembled, the damage to the template is reduced and the construction cost is reduced.

[0037] Example 1, reference Figure 5 , Figure 6and Figure 7 As shown, the connector male buckle 31 includes two limit hooks 311 inside, the connector female buckle 32 includes a limit block 321 inside, the limit hook 311 has a limit hole 316 for inserting the limit block 321, when the limit hook 311 is inserted into the connector female buckle 32, the limit block 321 is inserted into the limit hole 316 to form a fixed structure, the limit hook 311 is a key component inside the connector male buckle 31, each limit hook 311 includes a limit hole 316, the shape and size of this limit hole 316 match the limit block 321 in the connector female buckle 32. When the limit hook 311 contacts the limit block 321, the limit block 321 will naturally slide into the limit hole 316, thereby locking the two. The material of the limit block 321 is usually the same as that of the connector female buckle 32, with high hardness and wear resistance to ensure that it is not easily damaged during long-term use. When the connector male buckle 31 is docked with the connector female buckle 32, the limit hook 311 will first contact the limit block 321. As the connector male buckle 31 is further inserted, the limit block 321 will naturally slide into the limit hole 316 inside the limit hook 311, thereby forming a stable fixed structure. The interaction between the limit hook 311 and the limit block 321 ensures a stable connection between the connectors, which is not easy to loosen or fall off even when subjected to a large external force. The connector splicing and disassembly process is simple and quick, without the need for complex tools or additional operating steps.

[0038] The insertion end of the limit hook 311 is set as an inclined surface 317. When the limit hook 311 is inserted into the limit female buckle, the limit block 321 first contacts the inclined surface 317 of the limit hook 311, pushing the limit hook 311 to move, and the limit block 321 can be inserted into the limit hole 316 of the limit hook 311. The design of the inclined surface 317 plays a guiding and aligning role at the insertion end of the limit hook 311. When the connector male buckle 31 is docked with the connector female buckle 32, the limit block 321 first contacts the inclined surface 317 of the limit hook 311. This contact point guides the limit block 321 to move along the direction of the inclined surface 317. As the connector male buckle 31 and the connector female buckle 32 continue to move, the limit block 321 is inserted into the limit hole 316 of the limit hook 311. In this process, the limiting block 321 is tightly locked in the limiting hole 316. Once the limiting block 321 is fully inserted into the limiting hole 316, a stable fixed structure is formed between the connector male buckle 31 and the connector female buckle 32.

[0039] The limit hook 311 is also provided with a slide groove 313. A slide 312 is slidably provided in the connector male buckle 31. Both sides of the slide 312 are slidably provided in the slide groove 313 in the limit hook 311. When the slide 312 moves in the connector male buckle 31, it drives the two limit hooks 311 to move closer or farther away. The slide groove 313 is a guide rail structure provided on the limit hook 311, which is used to guide the slide 312 to slide inside it. The shape and size of the slide groove 313 are carefully designed to ensure that the slide 312 can move smoothly inside it and drive the limit hook 311 to move accordingly. When no external force is applied, the slide 312 is located at a certain middle position in the connector male buckle 31. At this time, the two limit hooks 311 maintain a certain opening angle so that the limit block 321 can be inserted into the connector female buckle 32.

[0040] A connecting rod 314 is also slidably provided on one side of the connector male buckle 31, one end of the connecting rod 314 is fixedly connected to the slide 312, and a spring 315 is also sleeved on the outside of the connector male buckle 31. The spring 315 is used to reset the slide 312. When the slide 312 is pulled and moved by an external force, the spring 315 will be compressed or stretched. Once the external force disappears, the spring 315 will use its elastic force to push the slide 312 back to the initial position to achieve automatic reset. The spring 315 can also maintain a certain tension between the slide 312 and the connector male buckle 31, which helps to ensure that the limit hook 311 maintains a stable opening angle when not affected by external forces.

[0041] When the template needs to be separated, pull the connecting rod 314, which moves the slide 312. Since the two sides of the slide 312 cooperate with the slide groove 313 in the limit hook 311, the limit hook 311 is moved closer, and the limit block 321 is disengaged from the limit hole 316 in the limit hook 311, thereby realizing the rapid disassembly of the template.

[0042] The connector male buckle 31 is a magnet, and the connector female buckle 32 is also a magnet. The connector male buckle 31 and the connector female buckle 32 are adsorbed and fixed when they are in contact, or the connector male buckle 31 is inserted into the connector female buckle 32 for fixation.

[0043] Example 2, reference Fig. 9 As shown, when the connector male buckle 31 approaches the connector female buckle 32, since both are magnets, they will immediately attract each other and quickly approach each other. This magnetic force greatly simplifies the splicing process without the need for complex alignment or additional fixing devices.

[0044] The connector male buckle 31 is inserted into the connector female buckle 32 , and the connector male buckle 31 and the connector female buckle 32 are fixed by a pin.

[0045] Example 3, reference Fig.10As shown, align the connector male buckle 31 with the insertion port of the connector female buckle 32 and slowly insert it. During the insertion process, it may be necessary to overcome certain resistance or make certain alignment adjustments. When the connector male buckle 31 is inserted to a certain depth, the pin hole on it will be aligned with the corresponding pin hole on the connector female buckle 32. The diameter of the pin should be slightly smaller than the diameter of the pin hole to ensure that it can be inserted smoothly and has a certain fastening force.

[0046] refer to Figure 4 As shown, the joint of the outer template 1 or the inner template 2 is a groove-protrusion structure, and the protrusion is inserted into the groove for positioning the adjacent outer template 1 and inner template 2. The groove-protrusion structure simplifies the splicing process between the templates and improves construction efficiency.

[0047] refer to Fig.11 As shown, the joint of the outer template 1 or the inner template 2 is a pin hole structure, the positioning pins are set on both sides of the outer template 1 or the inner template 2, and the positioning holes are set on the other two sides of the outer template 1 or the inner template 2. When the outer template 1 or the inner template 2 is spliced, the positioning pins are inserted into the positioning holes, and the outer template 1 or the inner template 2 is moved to the predetermined splicing position so that the positioning pins are aligned with the corresponding positioning holes. Then, the positioning pins are inserted into the positioning holes one by one until they are fully inserted and fixed. Through the cooperation of the positioning pins and the positioning holes, the precise docking between the templates can be ensured, and the construction accuracy can be improved. The insertion and fixation of the positioning pins can form a firm connection structure and enhance the overall stability and bearing capacity of the template.

[0049] S1: The staff splices multiple outer templates 1 together, the connector male buckle 31 and the connector female buckle 32 are coupled together, and the limit hook 311 will first contact the limit block 321. As the connector male buckle 31 is further inserted, the limit block 321 will naturally slide into the limit hole 316 inside the limit hook 311, thereby forming a stable fixed structure;

[0050] S2: The staff splices the multiple inner templates 2 together, the connector male buckle 31 and the connector female buckle 32 are coupled together, and the limit hook 311 will first contact the limit block 321.
