Description

Technical Field

[0001] This invention belongs to the field of concrete construction formwork technology, specifically relating to a seamless construction equipment for large-area concrete. Background Technology

[0002] In the seamless construction of large-area concrete floor structures, concrete shrinkage deformation is the dominant factor inducing cracks, and the skip-pour method is currently the mainstream construction technology for controlling such cracks.

[0003] During the skip-pour construction method, the formwork for each skip block must first be erected according to the pre-set segmentation plan. Then, following the principle of "intermittent pouring and non-continuous advancement," the concrete is poured in a skip-style manner within the erected skip blocks. That is, some skip blocks are poured first, and after the specified interval is met, the adjacent unpoured skip blocks are poured. The skip-pour construction method can solve the cracking problem of ultra-long, ultra-thick, and ultra-thin large-volume concrete structures. By releasing the early internal stress of the concrete through segmented pouring, it replaces the traditional post-pouring strip process and achieves seamless structural construction.

[0004] A related technology (Chinese patent CN114215363A) discloses a seamless construction device and method for large-area concrete floors, including a moving component and a feeding component. The moving component includes a guide rail, a support frame, and a first driving component. The support frame is slidably connected to the guide rail via the first driving component, and the sliding direction of the support frame is perpendicular to the length direction of the guide rail. The first driving component is used to drive the support frame to slide. The feeding component includes a hopper and a second driving component. The hopper is slidably connected to the support frame, and the sliding direction of the hopper is parallel to the length direction of the support frame. A discharge port is opened on the side of the hopper near the support frame. The second driving component is used to drive the hopper to slide. This method has the advantage of improving the work efficiency during seamless construction of large-area concrete floors.

[0005] In traditional skip-concrete construction, the overall formwork needs to be erected manually, with adjacent horizontal and vertical formwork sections erected one by one, and the joints connected and assembled to form the closed concrete pouring structure required. However, due to the irregularity and size differences of construction sites, each batch of large-area seamless concrete pouring requires a redesign of the formwork layout for the specific site and a completely new erection operation. This makes it impossible to reuse formwork materials across projects or batches, resulting in a large waste of formwork materials and increased construction costs. Summary of the Invention

[0006] To address the problems of existing technologies, which are affected by the irregularity and size differences of construction sites, requiring a complete redesign and erection of formwork for each batch of large-area seamless concrete construction, thus hindering cross-project or cross-batch reuse and resulting in significant waste of formwork materials and increased construction costs, this invention provides a large-area seamless concrete construction device. Through a freely assembled structure of a first formwork, a second formwork, and a partition plate, a detachable and reusable seamless concrete construction formwork is formed.

[0016] The large-area seamless concrete construction equipment of the present invention has the following advantages compared with the prior art: I. In existing large-area seamless concrete construction, the irregularity and size variations of construction sites necessitate redesigning the formwork layout and undertaking entirely new erection work for each batch of construction. This results in the inability to reuse formwork across projects or batches, significant waste of formwork materials, and increased construction costs. This invention addresses these issues by employing a freely assembled structure of a first formwork, a second formwork, and a partition plate to create a detachable and reusable seamless concrete construction formwork. By flexibly adjusting the relative positions of the second formwork and the partition plate, this formwork can adapt to irregular or differently sized construction sites without requiring a complete rebuild, enabling cross-project or cross-batch reuse. Furthermore, the adjustment method for different sites is quick and efficient, avoiding material waste and cost losses caused by the inability to reuse single-use formwork, and solving the problem of low construction efficiency resulting from multiple formwork assemblies in traditional technologies. II. In existing large-area concrete construction, the formwork is manually erected and connected piece by piece. This method suffers from several drawbacks: the accuracy of formwork splicing depends on the operator's experience, assembly errors can lead to insufficient sealing of sections, increasing the risk of grout leakage during concrete pouring, and overall erection efficiency is low, severely hindering construction progress. In this invention, the position adjustment of the partition plate relative to the second formwork is performed along the side wall of the second formwork, ensuring a tight fit before and after adjustment. Similarly, the position adjustment of the second formwork relative to the first formwork is performed along the side wall of the first formwork, ensuring a tight fit before and after adjustment. Under this adjustment mode, the accuracy of the adjusted and erected overall formwork depends on the distance between the first and second limiting grooves, rather than manual operation. The adjusted formwork can stably guarantee the fit and sealing of the joints, thus ensuring the sealing performance of each section and effectively avoiding the risk of grout leakage during subsequent concrete pouring. Furthermore, this standardized adjustment and section erection method is more efficient, with a quick and efficient adjustment process, significantly improving the overall progress of seamless large-area concrete construction. Thirdly, in this invention, by adjusting the spacing between two adjacent sets of second templates, the templates can completely cover concrete construction plots of different widths; by adjusting the spacing of multiple sets of partition plates between two adjacent sets of second templates, the space enclosed by the two adjacent sets of second templates can be divided into concrete construction areas of different sizes. Simultaneously, by utilizing the positional displacement of the partition plates, it can adapt to the irregular edges of the construction area, ensuring that the edges of the construction area have a stepped structure and are completely covered by this equipment. In other words, this invention, through a dual adjustment method of horizontal and vertical adjustment, can precisely adapt to the irregular edges of the construction area, ensuring that the construction area is completely covered. The edge of the concrete pouring block has a stepped structure and is completely covered by the equipment, avoiding blind spots or material waste caused by irregular edges. The relative position adjustment of the partition plate and the second template can flexibly meet the needs of dividing concrete pouring blocks of different widths or lengths, and the corresponding blocks can be flexibly arranged according to the terrain. Moreover, the above adjustment process can be completed without repeated disassembly and assembly of the equipment, which reduces the labor cost and time consumption of disassembly and assembly operations, and reduces the risk of damage caused by frequent disassembly and assembly. Ultimately, the equipment has better adjustment flexibility and stronger construction versatility, significantly improving the adaptability efficiency of cross-plot construction. IV. In this invention, the position adjustment of the second template relative to the first template and the position adjustment of the partition plate relative to the second template are both achieved through the adjustment locking unit. This adjustment locking unit only needs to drive the pressure plate to control whether the U-shaped blocks on both sides are locked in the corresponding positions, thereby completing the adjustment of the relative positions between the corresponding components and the locking after adjustment. This adjustment locking method significantly simplifies the position adjustment operation process. The switching between the two states of "unlocking adjustment" and "locking fixation" can be achieved with only a single drive action, reducing the difficulty of operation for operators and effectively improving the work efficiency of single component position adjustment. At the same time, the design of locking the two sets of U-shaped blocks synchronously by driving the pressure plate can ensure the dual position stability of the locked components after adjustment. Compared with the single set of U-shaped blocks positioning method, this dual position locking structure can further enhance the stability of component connection, reduce the risk of position displacement due to locking failure during long-term use, and thus ensure the structural reliability of the equipment during repeated use. V. In this invention, the vertical distance between the bottom edge of the first right-angled notch and the lower surface of the first limiting seat is greater than the height of the inner cavity of the first limiting groove embedded in the limiting seat. This ensures that when adjusting the second template relative to the first template, the limiting seat can completely disengage from the first limiting groove, and provides sufficient space for the second template to "move upward first and then horizontally". Similarly, the vertical distance between the bottom edge of the second right-angled notch and the lower surface of the second limiting seat is greater than the height of the inner cavity of the second limiting groove embedded in the limiting seat. This ensures that when adjusting the partition plate relative to the second template, the limiting seat can completely disengage from the second limiting groove, and provides an equal operating space for the partition plate. This dual height limitation setting, on the one hand, precisely controls the height of the partition plate, the second template, and the first template surrounding the template, conforming to the concrete pouring thickness standard, avoiding waste of materials and structural defects. On the other hand, it provides operating space, reduces the risk of component collision, improves adjustment efficiency, and eliminates the need to disassemble the equipment, enhancing adaptability and ensuring construction progress. VI. In this invention, the angle between the inclined end face and the side wall of the limiting seat is set to 20°-45°. Within this angle range, the inclined end face can clearly allow operators to observe whether the U-shaped plug is in the locked position inserted into the first or second slot cavity, avoiding misjudgment of the locked state due to blind spots or malfunction of the U-shaped plug component drive. On the other hand, it can ensure the contact area and force transmission efficiency when the limiting seat and the first or second slot cavity are engaged, ensuring sufficient connection strength between the two and preventing loosening after adjustment or during construction. The setting of this angle range reduces the time cost for operators to confirm the locked state, improves the construction error tolerance, and reduces structural wear during equipment use through stable connection strength. At the same time, it provides a reliable structural foundation for subsequent template adjustment and reuse, indirectly helping to improve construction efficiency and equipment cost-effectiveness. Moreover, the chamfering process of this angle is mature, which can reduce the production processing time of the chamfering process of this equipment and reduce manufacturing time costs. VII. In this invention, the connecting component used to connect the top plate and the two side limiting seats adopts a widely adaptable structure that is adjustable within a range. Specifically, by setting a first waist hole, when replacing the top plate and partition plate of the corresponding size, the position of the positioning bolt relative to the first waist hole can be adjusted to accurately match the position of the through hole opened on the top plate of different sizes, ensuring the accuracy of component connection. At the same time, relying on the flexible position adjustment characteristic of the positioning bolt relative to the first waist hole, the locking position of the positioning bolt can be adjusted as needed, thereby reserving sufficient observation space for whether the U-shaped insert at the through limiting seat is in a locked or disengaged state, effectively avoiding the problem of obstructed observation line of sight that is prone to occur under the fixed position installation method. 8. In this invention, by setting the U-shaped plug into a U-shaped structure, it is possible to ensure that the U-shaped plug achieves bidirectional locking in the front-back and horizontal directions at the corresponding position; that is, relying on the U-shaped structure, the limiting seat can be directly and stably locked in the corresponding first slot or second slot, avoiding the positional displacement problem that is easy to occur in unidirectional locking, and ensuring the stability of the component connection. 9. In this invention, the inclined groove is inclined. This structure can drive the U-shaped plug at the corresponding position to move horizontally by moving the drive rod vertically. That is, by utilizing the inclined transmission characteristics of the inclined groove, the vertical displacement of the drive rod is accurately converted into the function of adjusting the horizontal displacement of the U-shaped plug, realizing the efficient conversion between the two motion directions. This transmission method, on the one hand, avoids the displacement deviation that is easy to occur in manual adjustment through the directional transmission of the mechanical structure, ensuring the accuracy of the horizontal displacement of the U-shaped plug, and thus ensuring the locking accuracy when the U-shaped plug is engaged with the first slot and the second slot. On the other hand, only the drive rod needs to be operated to realize the synchronous adjustment of the two sets of U-shaped plugs, saving operation steps and adjustment time, improving the efficiency of state switching. At the same time, synchronous adjustment can also avoid uneven force on the components caused by the asynchronous displacement of the two sets of U-shaped plugs, reduce equipment wear, and provide a guarantee for the long-term stable use of the template. 10. In the existing market, the dismantling of formwork after the completion of seamless concrete construction is often done by direct dismantling. This method easily leads to the concrete sticking to the formwork surface, damaging the final finished effect of seamless concrete construction and increasing the difficulty of formwork cleaning. To address this problem, after the concrete pouring operation is completed, the entire formwork consisting of the partition plate, the second formwork, and the first formwork can be driven upward by existing hoisting equipment. During this process, the moving rod set on the side wall of the first formwork will be forced to move back and forth slightly along the inner cavity of the serpentine groove. The vibration generated by this displacement can help the formwork and the concrete surface achieve complete demolding, fundamentally avoiding the concrete sticking problem caused by the traditional direct dismantling method. This demolding method can achieve complete demolding, which can maximize the flatness and integrity of the concrete surface and ensure that the finished product quality of seamless construction meets the standards. On the other hand, the non-sticky demolding effect reduces the workload of subsequent formwork cleaning and maintenance, reduces the wear and tear of concrete residue on the formwork, extends the service life of the formwork, and further improves the cost-effectiveness of the formwork for cross-project and cross-batch recycling, indirectly reducing the overall construction cost. XI. In this invention, the vertical distance between the curved portion of the serpentine channel to one side and the curved portion to the other side is 0.5mm-5mm. This range can precisely control the demolding vibration amplitude. By limiting the vertical distance of 0.5mm-5mm along the serpentine channel, the amplitude of the moving rod's movement is limited, causing a small reciprocating vibration when the template is demolded. This effectively breaks the adhesion between the template and the formed concrete, avoiding the adhesion problem of traditional vertical demolding. It also prevents excessive vibration amplitude from causing surface pitting and edge damage to the concrete, ensuring the quality of concrete forming. At the same time, it avoids the moving rod getting stuck and parts wearing out due to too small a distance, and also prevents the curved section of the serpentine channel from being unevenly stressed and easily deformed due to too large a distance, extending the structural life of the equipment during repeated use and reducing maintenance costs. Furthermore, the lower limit of 0.5mm can meet the demolding requirements of thin-walled, high-precision concrete components, avoiding damage to the surface, while the upper limit of 5mm is suitable for ordinary plain concrete components, improving demolding efficiency and achieving flexible adaptation to different types of concrete construction. 12. In this invention, the grounding positioning plate is connected to the construction ground. This connection structure positions and supports the entire template system, consisting of the partition plate, the second template, and the first template, ensuring that the template completely covers the area to be constructed. This avoids blind spots or deviations in the concrete pouring area caused by incomplete template coverage, guaranteeing the integrity of the area for seamless large-area concrete construction. Simultaneously, the grounding positioning plate is connected to the ground via grounding bolts, second waist holes, and other connecting components. This method allows for quick installation and removal of the grounding positioning plate on the ground, eliminating the need for complex disassembly and assembly procedures. This quick installation and removal shortens the time for equipment setup and disassembly, improving efficiency in construction preparation and finishing stages. The simplified disassembly and assembly process reduces the difficulty of equipment transportation and storage, and is more conducive to the overall transfer and reuse of the equipment between different projects, further enhancing the equipment's cyclical value. In summary, this invention, through multi-dimensional improvements, achieves "high adaptability, high efficiency, high quality, and low cost" application of seamless concrete construction formwork equipment for large areas, providing a flexible and reliable technical solution for seamless construction of large areas of concrete: In terms of adaptability, it can flexibly handle irregular plots, components of different sizes, and terrain, and can be reused across projects without the need for customized special formwork; in terms of efficiency, it simplifies the disassembly and adjustment process, enabling quick disassembly and assembly, synchronous adjustment, and eliminating the need for repeated assembly, reducing operational difficulty and time costs, and improving the progress of the entire construction cycle; in terms of quality, through improvements in sealing and fitting, precise transmission, and controllable vibration, it avoids problems such as grout leakage, adhesion, and surface damage, ensuring the stability of the finished concrete product and the equipment structure; in terms of cost, it reduces material waste, equipment wear and maintenance costs, and extends the service life of the formwork.

[0018] The following are specific implementation cases and appendices. Figures 1 to 12 The present invention will be further described, but the present invention is not limited to these embodiments.

[0019] This invention relates to specialized formwork construction equipment for the pre-construction stage of large-area concrete construction, which can work in conjunction with commercially available concrete pouring equipment. Based on general technical specifications for large-area concrete construction, and combined with mature technologies in conventional lifting machinery and seamless construction, it ultimately achieves seamless construction of large-area concrete structures. This invention only improves formwork equipment for large-area concrete construction; therefore, the supporting equipment and specifications all adopt general technical methods, which will not be elaborated or limited here.

[0020] For details, please refer to 1 to 2. Figure 4As shown, a large-area seamless concrete construction device includes two sets of first templates 1 arranged parallel to each other, and also includes: second templates 2, partition plates 3, and a top plate 4. Multiple sets of second templates 2 are arranged vertically between the two sets of first templates 1, with adjacent second templates 2 arranged parallel to each other. Each set of second templates 2 has a first right-angle notch at both its front and rear ends. Multiple sets of partition plates 3 are arranged vertically between adjacent sets of second templates 2, with corresponding partition plates 3 arranged parallel to each other. The top plate 4 is centrally located and fixedly installed on the partition plates 3. The width of the top plate 4 is smaller than the width of the partition plates 3, and the edge of the top plate 4 forms a second right-angle notch with the edge of the partition plates 3. The partition plates 3, second templates 2, and first templates 1 together form a template for large-area seamless concrete construction, dividing the concrete area to be constructed into several blocks.

[0021] This invention employs a freely assembled structure consisting of a first template 1, a second template 2, and a partition plate 3 to create a detachable and reusable seamless concrete construction formwork system. Its core advantage lies in its ability to flexibly adjust the relative positions of the second template 2 and the partition plate 3, naturally adapting to various irregular plots and construction areas of different sizes without requiring the redesign and re-erection of the entire formwork system. This feature not only enables the recycling of formwork across different projects and batches but also fundamentally solves the problems of material waste and high costs caused by the single-use nature of traditional formwork through a quick and efficient site adaptation method, while overcoming the construction efficiency bottleneck caused by repeated assembly and construction.

[0022] This invention employs a side-wall fitting guide design for template position adjustment: when adjusting the position of the partition plate 3 relative to the second template 2, the partition plate 3 moves along the side wall of the second template 2 throughout the entire process, ensuring that the partition plate 3 and the side wall of the second template 2 remain tightly fitted before and after adjustment; similarly, when adjusting the position of the second template 2 relative to the first template 1, the second template 2 also moves along the side wall of the first template 1, ensuring that the fit between the second template 2 and the side wall of the first template 1 is not affected before and after adjustment. In this adjustment mode, the overall template erection accuracy is controlled by the distance between the first limiting groove 7 and the second limiting groove 10, eliminating reliance on operator experience and effectively avoiding errors caused by manual operation. After adjustment, the template joints can stably maintain a high degree of fit and sealing, fundamentally ensuring the sealing performance of each concrete pouring block and minimizing the risk of grout leakage during subsequent pouring. Simultaneously, this standardized adjustment and block erection process simplifies the operation steps, making the adjustment process efficient and fast, significantly shortening the template erection cycle for seamless large-area concrete construction, and powerfully promoting the overall construction progress.

[0023] This invention utilizes a dual approach: adjusting the spacing between adjacent sets of second templates 2 laterally and adjusting the spacing between partition plates 3 within the set longitudinally. This allows the templates to completely cover plots of varying widths and divide the area into construction zones of different sizes. By adjusting the displacement of the partition plates 3 to accommodate irregular edges, a stepped, full-coverage structure is achieved, avoiding blind spots and material waste. Furthermore, all adjustments require no repeated disassembly and reassembly of the equipment, reducing labor and time costs, minimizing equipment wear and tear, and enhancing equipment flexibility and versatility, efficiently adapting to cross-plot construction needs.

With the help of the spring force, the telescopic rod can be reset when there is no external force. The elastic element 16 only needs to meet the usage requirements of this application; no model limitation or excessive description is given for the aforementioned existing components. The pressure plate 17 is fixedly installed at the top of the elastic element 16. The pressure rod 18 is fixedly and vertically installed in the middle of the upper surface of the pressure plate 17. Two sets of drive rods 19 are provided, symmetrically installed at both ends of the lower surface of the pressure plate 17, and the drive rods 19 slide downwards into the inner cavity of the through groove 14. The drive pin 20 is fixedly installed at the bottom end of each set of drive rods 19. Two sets of U-shaped seats 21 are provided, symmetrically arranged along the inner cavity of the through groove 14. Inclined grooves 22 are symmetrically opened through the outer wall of each set of U-shaped seats 21. The inclined groove 22 is inclined upward towards the drive rod 19; two sets of U-shaped inserts 24 are provided, and the two sets of U-shaped inserts 24 are symmetrically installed on the outside of the two sets of U-shaped seats 21. The U-shaped inserts 24 are U-shaped; one end of the U-shaped insert 24 located at the first limiting groove 7 slides against the upper surface of the first limiting seat 6, and the other end is inserted into the inner cavity of the first slot 8 opened on the side wall of the first limiting groove 7; one end of the U-shaped insert 24 located at the second limiting seat 9 slides against the upper surface of the second limiting seat 9, and the other end is inserted into the inner cavity of the second slot 11 opened on the side wall of the second limiting groove 10; the handle 25 is fixed and vertically installed on the limiting seat 12.

[0027] The vertical distance between the bottom edge of the first right-angled notch and the lower surface of the first limiting seat 6 is greater than the height of the limiting seat 12 embedded in the inner cavity of the first limiting groove 7; the vertical distance between the bottom edge of the second right-angled notch and the lower surface of the second limiting seat 9 is greater than the height of the limiting seat 12 embedded in the inner cavity of the second limiting groove 10. This invention features a targeted design for the height of the two right-angled notches: the vertical distance between the bottom edge of the first right-angled notch and the lower surface of the first limiting seat 6 is set to be greater than the height of the limiting seat 12 embedded in the cavity of the first limiting groove 7. This design ensures that when adjusting the position of the second template 2 relative to the first template 1, the limiting seat 12 can be completely disengaged from the cavity of the first limiting groove 7, while also reserving sufficient operating space for the adjustment action of the second template 2 "first moving upwards and then moving horizontally". Similarly, the vertical distance between the bottom edge of the second right-angled notch and the lower surface of the second limiting seat 9 is also greater than the height of the limiting seat 12 embedded in the cavity of the second limiting groove 10, which ensures that when adjusting the partition plate 3 relative to the second template 2, the limiting seat 12 can be completely disengaged from the cavity of the second limiting groove 10, and provides the same operating space for the partition plate 3. This dual-height-limit design has two core advantages: First, it can precisely control the height of the template formed by the partition plate 3, the second template 2, and the first template 1, ensuring that it strictly matches the concrete pouring thickness standard and effectively avoiding problems such as wasted concrete or insufficient structural thickness due to height deviation; Second, by reserving sufficient operating space, it reduces the risk of collisions and jamming during component adjustment, improves the smoothness and efficiency of adjustment operations, and allows adjustment to be completed without disassembling the equipment, further enhancing the adaptability and flexibility of the equipment and providing a guarantee for the stable progress of construction.

[0028] This invention employs a U-shaped structure design for the U-shaped insert 24, which allows the U-shaped insert 24 to simultaneously achieve bidirectional locking in both the front-rear and horizontal directions at its corresponding installation position. Specifically, thanks to the unique shape of the U-shaped structure, the limiting seat 12 can be directly and stably locked in the corresponding first slot 8 or second slot 11 position, fundamentally solving the positional offset problem that easily occurs during unidirectional locking, and providing a reliable and stable guarantee for the connection between components.

[0029] This invention designs the inclined groove 22 as an inclined structure, which possesses a unique transmission function: when the drive rod 19 moves vertically, the inclined characteristics of the inclined groove 22 drive the corresponding U-shaped insert 24 to generate horizontal displacement. Essentially, it precisely converts the vertical displacement of the drive rod 19 into the horizontal adjustment displacement of the U-shaped insert 24, achieving efficient conversion between the two movement directions. This inclined transmission method has significant advantages: firstly, relying on the directional transmission logic of the mechanical structure, it avoids the displacement deviation problems common in manual adjustment, ensuring the accuracy of the horizontal displacement of the U-shaped insert 24, thereby guaranteeing the locking accuracy when the U-shaped insert 24 engages with the first slot 8 and the second slot 11; secondly, the operator only needs to manipulate the drive rod 19 to simultaneously adjust both sets of U-shaped inserts 24, reducing operation steps and adjustment time, and improving the switching efficiency of the locked / unlocked state of the U-shaped insert 24. Simultaneously, the synchronous adjustment of the two sets of U-shaped inserts 24 avoids uneven force on components due to asynchronous displacement, reducing equipment wear and providing a reliable guarantee for the long-term stable and cyclical use of the template.

[0030] In this invention, the relative position adjustment between the second template 2 and the first template 1, and between the partition plate 3 and the second template 2, is accomplished by the adjustment and locking unit. The unit's operation logic is simple and efficient: only a drive is needed to apply to the pressure plate 17 to control whether the U-shaped inserts 24 on both sides are locked in the corresponding positions, thus simultaneously achieving the adjustment and locking of the relative positions of the components. This adjustment and locking design offers significant advantages: on the one hand, it simplifies the operation process—switching between "unlocking adjustment" and "locking fixation" states with a single drive action reduces the difficulty of operation for operators and significantly improves the efficiency of adjusting the position of a single component; on the other hand, the structure of the pressure plate 17 driving the two sets of U-shaped inserts 24 to lock synchronously achieves stable dual-position locking. Compared to positioning with a single set of U-shaped inserts 24, this enhances the stability of the component connection, reduces positional shift problems caused by locking failure during long-term use, and ultimately ensures the structural reliability of the equipment during repeated use.

[0031] Main references Figure 8 and Figure 9 As shown, the adjusting snap-fit ​​unit also includes a guide groove 15 and a slider 23. The guide groove 15 is symmetrically opened on both sides of the inner wall of the through groove 14. One end of the slider 23 is slidably embedded in the inner cavity of the guide groove 15, and the other end is fixedly installed on the side wall of the U-shaped seat 21. When the U-shaped seat 21 is displaced under the external force of the drive rod 19, it can drive the slider 23 to move along the inner cavity of the corresponding guide groove 15, so as to limit and guide the displacement direction of the U-shaped seat 21, the slider 23, and the U-shaped insert 24. Moreover, both the slider 23 and the guide groove 15 are provided in two sets, which can ensure that the U-shaped seat 21 is evenly guided by the two sets of sliders 23, avoiding tilting caused by unilateral guidance.

[0032] Main references Figure 6As shown, the angle between the inclined end face 13 and the side wall of the limiting seat 12 is 20°-45°. This angle design has the dual advantages of convenient observation and reliable connection: From the observation angle, the inclined end face 13 within this range provides the operator with a clear field of vision, making it easy to confirm whether the U-shaped plug 24 is accurately inserted into the locking position of the first slot 8 or the second slot 11, effectively avoiding misjudgment of the locking status due to blind spots or failure of the U-shaped plug 24 to lock properly; from the connection performance perspective, this angle ensures sufficient contact area when the limiting seat 12 mates with the inner cavities of the first slot 8 and the second slot 11, ensuring efficient force transmission and providing sufficient connection strength to prevent loosening after adjustment or during construction. In addition, the setting of this angle range also brings multiple additional values: it reduces the time spent by the operator to confirm the locking status, improving the fault tolerance during construction; and it reduces structural wear during equipment use due to stable connection strength, laying a solid structural foundation for subsequent template adjustment and reuse, indirectly promoting construction efficiency and improving the cost-effectiveness of the equipment. Meanwhile, 20°-45° is a mature chamfering angle in the industry, which can shorten the production time of the chamfering process of this equipment and reduce the time cost of the manufacturing process.

[0033] Main references Figure 2 As shown, the second limiting seat 9 is connected to the limiting seats 12 at its front and rear ends via fixing blocks 26; thus, the fixing blocks 26 can be moved by the limiting seats 12 at the second limiting seat 9, thereby realizing the displacement adjustment of the second limiting seat 9 and the second template 2. The top plate 4 is connected to the limiting seats 12 at its left and right ends via connecting components; the position of the partition plate 3 at the bottom of the top plate 4 relative to the second template 2 can be adjusted by the limiting seats 12 at both ends of the top plate 4 driving the connecting components to move. The connecting components include: through holes 5, connecting pieces 27, first waist holes 28, and positioning bolts 29. The through holes 5 are symmetrically opened on the left and right sides of the top of each set of top plates 4; the connecting pieces 27 are correspondingly arranged on the front and rear sides of the top plate 4, and the connecting pieces 27 are fixedly connected to the side wall of the limiting seat 12; the first waist holes 28 are opened horizontally on the connecting pieces 27; the positioning bolts 29 are threaded through the first waist holes 28 and the inner cavity of the through holes 5, and the free end of the positioning bolts 29 is threaded with a locking nut. The positioning bolt 29 consists of a positioning bolt and a positioning nut. The positioning bolt passes through the first slot 28, and the positioning nut is screwed onto the positioning bolt 29 and tightly fitted against the side wall of the connecting piece 27, thereby enabling the positioning bolt 29 to be installed and locked onto the top plate 4 at the connecting piece 27. The positioning bolt 29 is a commercially available and mature component; this is existing technology, and it is sufficient to meet the usage requirements. Therefore, its model will not be described or limited here.

[0034] In this invention, the connecting assembly between the top plate 4 and the two side limiting seats 12 adopts a widely adaptable structural design that can be adjusted within a certain range. Specifically, by configuring the first waist hole 28, when it is necessary to replace the top plate 4 and the partition plate 3 of different sizes, it is only necessary to adjust the position of the positioning bolt 29 relative to the first waist hole 28 to accurately match the position of the through hole 5 opened on the top plate 4 of different sizes, thereby ensuring the accuracy of the connection of each component, without the need to design a special connection structure for different sized components. At the same time, by taking advantage of the characteristic that the positioning bolt 29 can be flexibly adjusted relative to the first waist hole 28, the locking position of the positioning bolt 29 can also be adjusted according to actual needs. This design can reserve sufficient observation space for the U-shaped insert 24 at the through limiting seat 12, making it convenient for operators to judge whether the U-shaped insert 24 is in a locked or disengaged state, effectively solving the problem of obstructed observation line of sight that easily occurs in traditional fixed position installation.

[0035] Currently, after large-area seamless concrete construction, formwork removal often employs a direct removal method. This method not only easily causes concrete to stick to the formwork, damaging the finished product, but also increases the difficulty of cleaning the formwork. To solve this problem, the following mainly refers to... Figure 1 , Figure 5 , Figures 10 to 12As shown, vibration demolding units are respectively provided on the outer sides of the two sets of first templates 1. Each set of vibration demolding units includes: grounding positioning plate 30, second waist hole 31, grounding bolt 32, vertical plate 33, serpentine through groove 34, tripod 35, moving rod 36 and hook 37. The grounding positioning plate 30 is set horizontally on the outer side of the first template 1. Multiple sets of second waist holes 31 are provided, and multiple sets of second waist holes 31 are respectively opened through the grounding positioning plate 30. The grounding bolt 32 is threaded through the inner cavity of the second waist hole 31, and the free end of the grounding bolt 32 is screwed downward into the ground. The grounding bolt 32 adopts a commercially available general-purpose anchor bolt for grounding. It can adopt a suitable shape and model to meet the usage requirements. It will not be described or limited here. In this invention, the grounding positioning plate 30 is connected to the construction ground and can position and support the entire template consisting of the partition plate 3, the second template 2, and the first template 1, ensuring that the template completely covers the area to be constructed, avoiding blind spots and pouring deviations, and ensuring the integrity of the construction. At the same time, the grounding positioning plate 30 can be quickly disassembled and installed on the ground through the grounding bolt 32 and the second waist hole 31, which can be completed without complicated procedures. This not only shortens the construction preparation and finishing time and improves efficiency, but also reduces the difficulty of equipment transportation and storage, facilitates cross-project reuse, and enhances the value of recycling. Multiple sets of vertical plates 33 are provided, and the multiple sets of vertical plates 33 are respectively vertically installed on the grounding positioning plate 30; a serpentine through groove 34 is opened on the vertical plate 33, and the opening trajectory of the serpentine through groove 34 is serpentine; two tripods 35 are fixedly installed on the outer side wall of the first template 1; a moving rod 36 is fixedly installed between two sets of tripods 35, and the moving rod 36 slides through the inner cavity of the serpentine through groove 34; four sets of hooks 37 are provided, and two sets of hooks 37 are symmetrically installed on the first limiting seat 6. The hooks 37 are compatible with existing market-standard cranes. Using the lifting end of the existing crane, the hooks are attached to four sets of hooks 37 to uniformly lift all components of the equipment except for the grounding positioning plate 30, the second waist hole 31, the grounding bolt 32, the vertical plate 33, and the serpentine channel 34. This allows all the first formwork 1, the second formwork 2, and the top plate 4 to detach from the already formed concrete with slight vibration, thus achieving formwork demolding and completing the overall seamless large-area concrete construction process. The existing cranes and large-area concrete construction techniques mentioned above are all existing technologies, using commonly available methods and models of equipment to meet the usage requirements of this application; therefore, they will not be elaborated upon or limited here.

[0036] After the concrete is poured, the present invention uses existing hoisting equipment to pull the template consisting of the partition plate 3, the second template 2, and the first template 1 upward as a whole. During this process, the moving rod 36 on the side wall of the first template 1 will be forced to move back and forth slightly along the inner cavity of the serpentine groove 34. The resulting vibration energy helps the template to be completely separated from the concrete, fundamentally avoiding the adhesion problem of traditional direct dismantling.

[0037] This demolding method has obvious advantages: it can ensure that the concrete surface is flat and intact, thus ensuring construction quality, while reducing the cleaning work of the formwork, reducing the wear and tear on the formwork caused by concrete residue, extending the life of the formwork, improving its cost-effectiveness for reuse across projects and batches, and thus indirectly reducing construction costs.

[0038] Main references Figure 12 As shown, the vertical distance between the bent portions of the serpentine channel 34 on one side and the bent portions on the other side ranges from 0.5mm to 5mm. This precise spacing design is key to controlling the demolding vibration amplitude: this spacing range strictly limits the amplitude of the moving rod 36's movement along the serpentine channel 34, causing small reciprocating vibrations during demolding. This effectively breaks the adhesion between the template and the formed concrete, completely solving the adhesion problem of traditional vertical demolding; it also avoids excessive vibration amplitude causing surface pitting and edge damage to the concrete, ensuring that the concrete forming quality meets standards. Simultaneously, this spacing range also considers the stability of equipment operation: a spacing of not less than 0.5mm prevents the moving rod 36 from jamming during movement, reducing component wear; a spacing of not more than 5mm prevents the bent sections of the serpentine channel 34 from easily deforming due to uneven stress, extending the structural life of the equipment for repeated use and reducing maintenance costs. In addition, the upper and lower limits of the range are designed to be flexible and adaptable: the lower limit of 0.5mm can meet the demolding requirements of thin-walled, high-precision concrete components and avoid damage to the surface of the components; the upper limit of 5mm is suitable for ordinary plain concrete components, which can further improve demolding efficiency and achieve full coverage of different types of concrete construction scenarios.

[0039] It is worth noting that in this equipment, the height of the partition plate 3 and the height of the bottom edge of the second right-angled notch at the end of the second template 2 from the lower surface of the second template 2 both meet the requirements for concrete pouring thickness. That is, the above height range can accommodate the concrete pouring thickness requirements of the area to be constructed, and is not directly related to the height of the top plate 4 or the height of the upper surface of the second template 2. Furthermore, during conventional large-area seamless concrete construction, the partition plate 3 and the top plate 4 use the same specifications to divide adjacent second templates 2 into concrete blocks of the same size to be poured. To accommodate concrete pouring blocks with irregular edges, or when the same specifications of partition plate 3 cannot meet the requirement of complete partitioning, the length of the partition plate 3 can be adjusted to meet the needs of separating blocks of different sizes. In other words, the model of the partition plate 3 can be selected and configured as needed.

[0040] The working principle of a large-area seamless concrete construction equipment in this embodiment is as follows: Pre-installation positioning of the equipment: First, place the two sets of grounding positioning plates 30 corresponding to each other in parallel so that the construction area falls between the two sets of grounding positioning plates 30; then, thread the multiple grounding bolts 32 of each grounding positioning plate 30 through the corresponding second waist hole 31, and screw the bottom end of the grounding bolts 32 into the ground base by rotating them to achieve locking and fixing of the equipment on the construction ground, providing a stable foundation for subsequent operations; The appropriate number of second templates 2 is determined according to the size of the area to be constructed. The horizontal spacing between adjacent second templates 2 is adjusted to cover the entire area to be constructed, and the second templates 2 are kept perpendicular to the two sets of first templates 1 in front and behind. The adjustment steps for assembling the second templates 2 into different first limiting grooves 7 are as follows: Press down on the pressure rod 18 at the top of the second template 2 to be adjusted, forcing the elastic element 16 to compress and deform, and simultaneously driving the two sets of driving rods 19 and driving pins 20 at the bottom of the pressure rod 18 to move down. The two sets of driving pins 20 slide along the inner cavity of the corresponding inclined groove 22, driving the two sets of U-shaped inserts 24 to retract into the inner cavity of the through groove 14, so that the U-shaped inserts 24 are disengaged from the inner cavity of the first slot 8 of the current first limiting groove 7. At this time, the limiting seat 12 has no horizontal or vertical limitation in the inner cavity of the first limiting groove 7. Pulling the handle 25 upward causes the limiting seat 12 to move upward, thereby causing the fixing block 26, the second limiting seat 9, and the second template 2 at the bottom of the second limiting seat 9 to move upward relative to the first template 1, until the two sets of limiting seats 12 on the second limiting seat 9 completely leave the corresponding inner cavity of the first limiting groove 7. Move the limiting seat 12, the fixing block 26, and the second limiting seat 9 in the horizontal direction to adjust the horizontal position of the second template 2 relative to the first template 1. After the adjustment is completed, place the two sets of limiting seats 12 on the second limiting seat 9 vertically into the inner cavity of the first limiting groove 7 at the target position to remove the external pressure drive on the pressure rod 18. Through the elastic reset of the elastic element 16, the pressure plate 17, the drive rod 19, and the drive pin 20 move upward, pushing the U-shaped seat 21, the slider 23, and the U-shaped insert 24 to move outward, so that the U-shaped insert 24 automatically snaps into the inner cavity of the target first slot 8, realizing the locking of the second limiting seat 9 and the second template 2 at the first template 1. Finally, the horizontal displacement adjustment and locking of the second template 2 relative to the first template 1 were completed, ensuring that multiple sets of second template 2 fully cover the area to be constructed; After the horizontal position of the second template 2 relative to the first template 1 is adjusted, the corresponding length of the partition plate 3 and the top plate 4 are matched according to the spacing between the two adjacent sets of second templates 2, and the partition plate 3 is assembled between the two sets of second templates 2. During operation, the positioning bolt 29 is inserted into the through hole 5 of the top plate 4 of the appropriate length, and the nut of the positioning bolt 29 is used to lock it in the position of the two sets of connecting pieces 27, so that the top plate 4 is fixed between the corresponding two sets of connecting pieces 27, thereby realizing the connection and assembly of the top plate 4 and the partition plate 3 between the two sets of limiting seats 12. Next, complete the assembly of the partition plate 3 and the top plate 4 between the adjacent second templates 2. Alternatively, this method can be used to adjust the spacing between adjacent partition plates 3 to meet the adjustment requirements of different concrete block sizes. The specific operation steps are as follows: Following the aforementioned operation logic, press down on the pressure rods 18 on both sides of the top plate 4 to cause the U-shaped inserts 24 on the limiting seats 12 at both ends of the top plate 4 to disengage from the inner cavity of the second slot 11, thereby releasing the limiting seats 12 from their limiting positions in the corresponding second limiting groove 10. Lift the handles 25 at the two sets of limiting seats 12 on the top plate 4 upwards to drive the limiting seats 12 on both sides, the connecting pieces 27, and the top plate 4 and partition plate 3 to move up and down together. Adjust the front and rear positions of the partition plate 3 and the top plate 4 relative to the adjacent second templates 2, and place the limiting seats 12 in the inner cavity of the target second limiting groove 10 so that the partition plate 3 and the area enclosed by the two sets of second templates 2 on the left and right are adapted to the area to be constructed, or adapted to the irregular edge of the area to be constructed, ensuring that the edge to be constructed is stepped and fully covered by this equipment. After adjustment, remove the external force of the pressure rod 18 on the top plate 4, and use the elastic restoring force of the elastic element 16 to push the U-shaped insert 24 into the inner cavity of the second slot 11 at the target position, so as to achieve a stable connection and lock between the top plate 4 and the partition plate 3 at the second template 2 after position adjustment. Furthermore, the height at which the partition plate 3 is raised relative to the second template 2 must be such that the limiting seats 12 on both sides of the top plate 4 can completely disengage from the inner cavity of the second limiting groove 10; similarly, the height at which the second template 2 is raised relative to the first template 1 must ensure that the limiting seats 12 on both sides of the second template 2 can completely disengage from the inner cavity of the first limiting groove 7. This height setting ensures that, on the one hand, the template formed by the partition plate 3, the second template 2, and the first template 1 meets the thickness requirements for seamless concrete pouring; on the other hand, it provides sufficient operating space for the partition plate 3 or the second template 2 to be raised to disengage the limiting seats 12 from the corresponding first slot 8 or first limiting groove 7, thus ensuring the feasibility of adjusting the position of the partition plate 3 and the second template 2. For the different blocks enclosed by partition plate 3, second template 2, and first template 1, the existing general skip-pour method is applied, following the principle of block planning and inter-block construction to carry out concrete pouring. After the concrete has cured for the required time, four sets of hooks 37 are used to lift it upwards using conventional lifting machinery. As the hooks 37 rise, the first limit seat 6, first template 1, second limit seat 9, second template 2, partition plate 3, and tripod 35 move upwards synchronously as a whole, causing the moving rod 36 installed at the tripod 35 to vibrate slightly and move upwards along the inner cavity of the serpentine through groove 34, thereby causing the partition plate 3, second template 2, and first template 1 to detach from the formed concrete module and complete demolding. Compared with the traditional vertical demolding, this method can effectively reduce the adhesion problem between the template and the concrete block, improve demolding efficiency, and provide convenience for the overall dismantling and recycling of the equipment. After the overall concrete construction of the block is completed, the grounding bolt 32 can be unscrewed from its corresponding position, thus separating the grounding positioning plate 30 from the ground and completing the overall removal of the equipment from the construction site. After routine cleaning and maintenance, the dismantled equipment can be used in the next large-area seamless concrete construction scenario, achieving equipment reuse.

[0041] Therefore, this invention achieves "high adaptability, high efficiency, high quality, and low cost" application of seamless concrete construction formwork equipment through multi-dimensional improvements, providing a flexible and reliable technical solution for seamless large-area concrete construction: In terms of adaptability, it can flexibly handle irregular plots, components of different sizes, and terrain, and can be reused across projects without the need for customized special formwork; in terms of efficiency, it simplifies the disassembly and adjustment process, enabling quick disassembly and assembly, synchronous adjustment, and eliminating the need for repeated assembly, reducing operational difficulty and time costs, and improving the progress of the entire construction cycle; in terms of quality, through improvements in sealing and fitting, precise transmission, and controllable vibration, it avoids problems such as grout leakage, adhesion, and surface damage, ensuring the stability of the finished concrete product and the equipment structure; in terms of cost, it reduces material waste, equipment wear and maintenance costs, and extends the service life of the formwork.

[0042] In addition, this equipment has been used and practiced in the following locations, as detailed below: Application Scenario 1: Irregular road surfaces in urban areas (such as street renovation in old urban areas, construction at irregular intersections): Scenario requirements: Construction sites are often irregular polygons and need to be adapted to driveways / sidewalks of different widths. Traditional formwork requires customization in sections, resulting in low assembly and disassembly efficiency and easy leakage of grout due to poor edge sealing.

[0043] Effectiveness of this equipment application: 1. Adaptability Advantage: Through the free assembly structure of the first template 1, the second template 2, and the partition plate 3, and the dual adjustment of the horizontal and vertical directions, it can flexibly fit the irregular edges of the road surface. With the help of the displacement of the partition plate 3, the edge to be constructed is fully covered in a stepped shape. It can adapt to different lane sizes of 2-8 meters without the need for customized special templates, and the cross-project reuse rate is increased by more than 80%.

[0044] 2. Quality and efficiency advantages: The fitting and adjustment mode of the partition plate 3 along the side wall of the second template 2 and the second template 2 along the side wall of the first template 1, combined with the bidirectional locking of the U-shaped U-shaped insert 24, ensures the sealing of the road surface splice and reduces the grout leakage rate to below 0.5%; at the same time, the quick-release and quick-installation ground positioning plate 30 ground connection design shortens the single-section road surface template construction time to 1 / 3 of the traditional method, reducing the traffic control time in the old city.

[0045] Application Scenario 2: Construction of flooring for large industrial parks / logistics warehouses: Scenario requirements: The construction area is large, exceeding 1,000 square meters, and needs to be divided into different functional areas such as loading and unloading areas and storage areas. It also requires a high degree of flatness of the ground and needs to be completed quickly to minimize the impact on the park's operation.

[0046] Effectiveness of this equipment application: 1. Efficiency and cost advantages: The single drive operation of the adjusting snap-fit ​​unit pressure plate 17 and U-shaped insert 24, along with the synchronous transmission of the tilting groove 22, enables rapid adjustment of multiple sets of templates. A team of 10 people can complete the erection of 300㎡ blocks per day, which is twice as efficient as the traditional manual block-by-block erection. The transfer from the storage area of ​​Park A to the loading and unloading area of ​​Park B enables the cross-batch recycling of templates, reducing material waste by 60% and reducing the construction cost per square meter by 15-20 yuan.

[0047] 2. Quality Advantages: The vibration demolding design, with the 36-position moving rod reciprocating along a serpentine groove at 340.5-5mm intervals, prevents concrete adhesion, ensuring the surface flatness error is controlled within 2mm / 2m, meeting the ground strength requirements for high-frequency logistics forklift operations; the double right-angle notch height design ensures uniform concrete pouring thickness, with a standard thickness deviation of ≤3mm for 150mm, and no structural defects. Application Scenario 3: Construction of multi-specification thin-walled decorative concrete components (such as exterior facade decorative panels of commercial complexes, and flower beds for landscape walkways): Scenario requirements: The components are thin, usually in the range of 50-100mm, and come in various sizes, such as 1.2m×0.8m and 1.5m×1.0m. Surface damage must be avoided during demolding, and template specifications need to be changed frequently to adapt to different design schemes.

[0048] Effectiveness of this equipment application: 1. Adaptability and Quality Advantages: The adjustable connection components of the top plate 4 and the limiting seat 12, with the first waist hole 28 and the positioning bolt 29, can quickly adapt to components of different sizes. After replacing the partition plate 3 and the top plate 4, the mounting hole of the through hole 5 can be accurately connected by adjusting the position of the positioning bolt 29, without the need to redesign the connection structure. The lower limit setting of the serpentine groove 34 with a serpentine spacing of 0.5mm makes the demolding vibration amplitude gentle, and the surface of the thin-walled component is free of pitting and the edges and corners are free of damage. The finished product qualification rate is increased from 85% in the traditional direct demolding method to 99%.

[0049] 2. Operational advantages: The 20-45° angle between the inclined end face 13 and the side wall of the limiting seat 12 makes it easy for operators to observe the locking status of the U-shaped insert 24 in real time, avoiding component displacement due to misjudgment. At the same time, the mature chamfering process shortens the template processing cycle by 3-5 days, enabling rapid response to the facade design change requirements of commercial projects.
