Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to an automatic clamping grout pouring template device. Background Technology

[0002] In the field of building construction, vertical concrete walls such as shear walls, pool walls, and retaining walls are typically constructed using on-site casting. With the development of building technology, the practice of using lightweight materials for on-site casting to replace traditional blocks or wall panels for infill wall construction is becoming increasingly common. Regardless of the type of wall, the on-site casting process still requires the formation of formwork.

[0003] Currently, most formwork assembly still relies on manual labor, with a small amount of modular assembly machinery used for auxiliary installation. In practice, the common method is to stack the formwork layer by layer from bottom to top, or to assemble it in sections from one side to the other to form a complete formwork cavity. After assembly, the formwork needs to be reinforced with tie rods and other measures. During this process, the formwork units often need to be lifted from the ground to the designed floor height and stably supported on top of the already installed formwork units below or on wall support points. However, whether using traditional manual assembly or machinery-assisted construction, this transition from being lifted to being suspended in mid-air typically relies on manual prying, alignment, and temporary support at height. This is not only labor-intensive and inefficient, but also makes it difficult to ensure precise alignment and tight fit between upper and lower layers of formwork, easily leading to quality defects such as misalignment and grout leakage at the formwork joints, affecting the final quality of the wall. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an automatic clamping grout pouring formwork device, which can automatically complete the transition of the unit from a supported to a suspended state when the formwork is stacked layer by layer, without the need for manual high-altitude intervention, ensuring smooth and tight joints and improving construction quality and efficiency.

[0005] An automatic clamping slurry casting template device according to an embodiment of the present invention includes: a frame having a main groove extending vertically, and a plurality of branch grooves intersecting and communicating with the main groove at intervals along the vertical direction, the branch grooves extending horizontally; a plurality of clamping modules, each clamping module including a load-bearing rod assembly and a pair of clamping units that can open and close relative to the load-bearing rod assembly; a lifting mechanism disposed on the frame, the lifting mechanism being configured to drive the load-bearing rod assembly to slide along the main groove to the intersection of the main groove and one of the branch grooves; and a pushing mechanism disposed on the frame, the pushing mechanism being configured to drive the load-bearing rod assembly to slide from the intersection of the main groove and one of the branch grooves into one of the branch grooves; the load-bearing rod assemblies of the plurality of clamping modules are sequentially slid into the plurality of branch grooves under the drive of the lifting mechanism and the pushing mechanism, so that the clamping units of the plurality of clamping modules are sequentially spliced ​​from top to bottom to form a casting mold cavity.

[0006] The invention offers at least the following advantages: By incorporating a load-bearing rod assembly and utilizing the main and branch slots on the frame, the technical solution achieves smooth operation and load transfer of the clamping module. Specifically, after the clamping module is lifted to a predetermined height by the lifting mechanism, it is smoothly pushed to the pouring position along the branch slot by the propulsion mechanism, and the load-bearing rod assembly is engaged in the branch slot, thereby smoothly transferring the load of the clamping module from the lifting mechanism to the branch slot. This process ensures that the template modules can smoothly and accurately transition from a supported state to a suspended support state when stacked layer by layer, opening up a new method for implementing wall templates. Simultaneously, the lifting and propulsion mechanisms can be reset and the next clamping module can be installed, forming a smooth automated construction process. This effectively avoids problems such as difficulties in template correction, misalignment of joints, and safety hazards caused by high-altitude operations in traditional construction methods, improving the construction efficiency, forming quality, and operational safety of vertical wall grout pouring.

[0007] According to some embodiments of the present invention, the clamping unit includes a clamping arm, and a template is provided at the front end of the clamping arm.

[0022] Please refer to Figures 1 to 4This embodiment discloses an automatic clamping slurry casting template device, including a frame 1, multiple clamping modules 4, a lifting mechanism 2, and a pushing mechanism 3. The frame 1 has a main groove extending vertically, and multiple branch grooves that intersect and communicate with the main groove are distributed at intervals along the vertical direction. The branch grooves extend horizontally. Each clamping module 4 includes a load-bearing rod group and a pair of clamping units that can open and close relative to the load-bearing rod group. The lifting mechanism 2 is mounted on the frame 1 and is configured to drive the load-bearing rod group to slide along the main groove to the intersection of the main groove and one of the branch grooves. The pushing mechanism 3 is mounted on the frame 1 and is configured to drive the load-bearing rod group to slide from the intersection of the main groove and one of the branch grooves into one of the branch grooves. The load-bearing rod groups of the multiple clamping modules 4 slide sequentially into the multiple branch grooves under the drive of the lifting mechanism 2 and the pushing mechanism 3, so that the clamping units of the multiple clamping modules 4 are sequentially spliced ​​from top to bottom to form the casting mold cavity.

[0023] Please refer to Figures 1 to 3 This embodiment discloses an automatic clamping grout casting template device, including a frame 1, a lifting mechanism 2, a pushing mechanism 3, and multiple clamping modules 4. For ease of description, the pushing direction of the pushing mechanism 3 is defined as the front-back direction, wherein the side closer to the casting wall is the front side. The frame 1 has a main groove extending vertically, and multiple branch grooves extending horizontally and communicating with it are spaced apart in the vertical direction. The branch grooves are used to support the clamping modules 4 after they move to the casting position. The lifting mechanism 2 and the pushing mechanism 3 are both mounted on the frame 1. The lifting mechanism 2 is used to drive the clamping modules 4 to move vertically, and the pushing mechanism 3 is used to drive the clamping modules 4 to move horizontally. Each clamping module 4 includes a load-bearing rod group and a pair of clamping units that can open and close relative to the load-bearing rod group.

[0024] During operation, the lifting mechanism 2 drives the load-bearing rod assembly to slide along the main channel until it reaches the intersection of the main channel and the target branch channel. Subsequently, the pushing mechanism 3 drives the load-bearing rod assembly to slide from the intersection of the main channel and the target branch channel into the target branch channel. Following this process, the load-bearing rod assemblies of multiple clamping modules 4 move one by one into their respective branch channels under the sequential drive of the lifting mechanism 2 and the pushing mechanism 3, thereby allowing the clamping units of multiple clamping modules 4 to be sequentially spliced ​​from top to bottom to form a complete mold cavity to be poured.

[0025] Therefore, the technical solution of this invention, by setting up a load-bearing rod assembly and cooperating with the main slot and branch slots opened on the frame 1, realizes the smooth operation and load transfer of the clamping module 4. Specifically, after the clamping module 4 is lifted to a predetermined height by the lifting mechanism 2, it is smoothly pushed to the pouring position along the branch slot by the pushing mechanism 3, and the load-bearing rod assembly is engaged in the branch slot, thereby smoothly transferring the load-bearing load of the clamping module 4 from the lifting mechanism 2 to the branch slot. This process ensures that the template 431 modules can smoothly and accurately complete the transition from the lifting state to the suspended support state when stacked layer by layer. At the same time, the lifting mechanism 2 and the pushing mechanism 3 can be reset and the next clamping module 4 can be installed, forming a smooth automated construction process, thereby effectively avoiding the problems of difficult template 431 correction, joint misalignment and safety hazards caused by high-altitude operations in traditional construction methods, and improving the construction efficiency, forming quality and operation safety of vertical wall grout pouring.

[0026] It should be noted that in some specific embodiments of the present invention, the connection relationship between the propulsion mechanism 3 and the lifting mechanism 2 can be flexibly designed according to the needs of construction efficiency and structural simplification. As an optional implementation, the propulsion mechanism 3 and the lifting mechanism 2 are fixedly connected, forming an integral lifting unit. In this structure, the propulsion mechanism 3 rises and falls synchronously with the lifting mechanism 2, without the need for an independent lifting drive component, but it still needs to be connected to the frame 1 through a sliding pair to limit its horizontal degree of freedom, ensuring its stability during the lifting process and its positional accuracy when docking with the guide rod 42. Therefore, when the lifting mechanism 2 drives the clamping module 4 to rise, the propulsion mechanism 3 rises accordingly; when the clamping module 4 is in place and the propulsion mechanism 3 has completed pushing, the propulsion mechanism 3 falls and resets together with the lifting mechanism 2. This implementation is simple in structure and convenient to control, which not only reduces additional lifting drive components and control systems, but also reduces equipment costs and failure rates.

[0027] As an alternative implementation, the propulsion mechanism 3 is independently and slidably mounted on the frame 1, meaning there is no fixed connection between the propulsion mechanism 3 and the lifting mechanism 2, allowing them to move relatively independently in the vertical direction. In this structure, the propulsion mechanism 3 can be equipped with an independent lifting drive element, or its position can be adjusted through counterweights, manual adjustment, or other means. Therefore, when multiple clamping modules 4 operate alternately, the independently mounted propulsion mechanism 3 can achieve more flexible scheduling. For example, when one clamping module 4 has completed pouring and needs to be dismantled, the propulsion mechanism 3 can independently move to another height and dock with another clamping module 4 while the lifting mechanism 2 descends, thereby enabling parallel operation of multiple clamping modules 4 and improving construction efficiency.

[0028] In some specific embodiments of the present invention, the bottom of the frame 1 is provided with multiple wheels to facilitate flexible movement and quick positioning of the frame 1 on the construction site. Furthermore, the wheels are preferably swivel casters to facilitate direction adjustment; at least one of the wheels is equipped with a braking device to lock the frame 1 after it is in place, preventing accidental movement during construction.

[0029] In some specific embodiments of the present invention, the lifting mechanism 2 is a hydraulic lifting platform 22, a screw lifting mechanism 2, or a scissor lift.

[0030] In some specific embodiments of the present invention, the clamping unit includes a clamping arm 43, and a template 431 is provided at the front end of the clamping arm 43. When the clamping arm 43 is closed, the templates 431 of the two clamping units surround and form a mold cavity that matches the cross-sectional shape of the wall to be poured.

[0031] like Figure 2 As shown, a template 431 is fixedly connected to the front end of each clamping arm 43, and the two clamping arms 43 of the two clamping units can open and close relative to the load-bearing rod assembly. When the two clamping arms 43 are closed, the two templates 431 fit together, thereby forming a mold cavity that matches the cross-sectional shape of the wall to be poured. Furthermore, the device also includes a tensioning and closing drive assembly 44, which is connected between the two clamping arms 43 and can drive the two clamping arms 43 to rotate relative to each other, so as to realize the automatic opening or closing of the clamping unit.

[0032] In some specific embodiments of the present invention, the closing timing of the two clamping arms 43 can be flexibly selected according to the actual construction process. Specifically, in one embodiment, after the clamping module 4 is assembled on the ground, the opening and closing drive assembly 44 first drives the two clamping arms 43 to close, so that the two molds fit together to form a mold cavity. Then, the lifting mechanism 2 drives the entire clamping module 4 to move vertically to a preset height, and then the pushing mechanism 3 pushes it to the pouring position and locks it in the first branch groove 111 and the second branch groove 121. This embodiment effectively reduces the lateral dimension and avoids interference with the surrounding structure by keeping the clamping arms 43 in a closed state during the lifting and pushing process, and is suitable for scenarios where the construction space is relatively compact. In another embodiment, the clamping module 4 is first raised to a preset height under the drive of the lifting mechanism 2, and then pushed to the pouring position by the pushing mechanism 3. After the support rod 41 is locked into the first branch groove 111 at the corresponding height and the guide rod 42 is locked into the second branch groove 121 at the corresponding height, the opening and closing drive assembly 44 drives the two clamping arms 43 to close, so that the two molds fit together to form a mold cavity. This implementation is suitable for scenarios where mold alignment is required after placement, such as when the mold has a special alignment structure or when it is necessary to avoid damaging the mold surface coating when closing on the ground. Regardless of the implementation method used, grout pouring can proceed once all clamping modules 4 are in place and the two clamping arms 43 are closed. After pouring is completed and the grout reaches the preset strength, the opening and closing drive assembly 44 drives the two clamping arms 43 to open, causing the mold to detach from the poured wall. Subsequently, the clamping modules 4 can be disassembled and retrieved by descending with the lifting mechanism 2.

[0033] In this specific embodiment, the opening and closing drive assembly 44 is a hydraulic cylinder, with its cylinder body hinged to one of the clamping arms 43 and its piston rod hinged to the other clamping arm 43. By controlling the extension and retraction of the hydraulic cylinder, the opening and closing of the two clamping arms 43 can be achieved. Preferably, the hydraulic cylinder is a double-acting hydraulic cylinder, that is, the movement of the piston in both relative directions is driven by hydraulic pressure, thereby realizing the active opening and closing of the clamping arms, improving control accuracy and response speed. It is understood that in other embodiments, the opening and closing drive assembly 44 may also be a cylinder, an electric actuator, or other linear drive elements.

[0034] In some specific embodiments of the present invention, the template 431 includes an upper template section 4312 and a lower template section 4313 fixedly connected to the clamping arm 43. The upper template section 4312 is positioned on top of the lower template section 4313, both located on the same vertical plane, and the clamping arm 43 is located between the upper template section 4312 and the lower template section 4313. Specifically, the template 431 is divided into standard and non-standard types. The standard template has an upper template section 4312 and a lower template section 4313 with a standardized design of equal height, suitable for wall construction at standard floor heights. That is, when multiple clamping modules 4 are stacked layer by layer, the total height of the mold remains constant, forming a continuous and flat mold cavity. The non-standard template has an upper template section 4312 and a lower template section 4313 with unequal segment heights, meaning one of the upper template 4312 and the lower template 4313 is taller than the other. The total height of the clamping modules 4 is matched to the non-standard floor height by adjusting the height of a certain section of the template.

[0035] This segmented design not only addresses variations in floor height but also flexibly solves the problem of wall height variations caused by structural differences within the same standard floor. For example, in the construction of a standard floor, most walls have a uniform height and can be directly poured using a mold cavity formed by stacking standard panels layer by layer. However, when a main beam is installed above a section of wall, causing a reduction in the actual pouring height of that section, simply select a non-standard panel at that location, reduce the height of its upper mold section 4312 by the corresponding height, and continue stacking standard panels for the remaining portion. This achieves precise matching of the wall section without needing to replace the entire formwork system due to local structural differences.

[0036] In other specific embodiments of the present invention, the clamping arm 43 is constructed as a multi-degree-of-freedom adjustable robotic arm structure. In this clamping module 4, the horizontal height of the clamping arm 43 at the template 431 is not at the same horizontal height as the horizontal height of the clamping arm 43 at the frame 1. In other words, there is a height difference between the connection point of the clamping arm 43 on the frame 1 side and its connection point on the template 431 side. This height difference is achieved by the multi-degree-of-freedom adjustment of the clamping arm 43 itself, rather than relying on the height difference between the upper mold section 4312 and the lower mold section 4313 of the template 431. This structural design allows the overall height of the template 431 to be adjusted by the robotic arm of the clamping arm 43, thus providing a flexible adaptation solution when the height of the frame 1 differs significantly from the height of the wall to be poured. During actual construction, the clamping arm 43 of the multi-degree-of-freedom robotic arm structure can be used in combination with the clamping arm 43 of the non-multi-degree-of-freedom robotic arm structure. By adjusting the vertical position and angle of the multi-degree-of-freedom robotic arm, the template 431 of different clamping modules 4 can quickly adapt to the height changes of various parts of the wall, without the need to frequently replace the template 431 or adjust the position of the frame 1, thus improving construction efficiency and equipment versatility.

[0037] In some specific embodiments of the present invention, the load-bearing rod assembly includes: a guide rod 42, which is detachably connected to the output end of the lifting mechanism 2, the guide rod 42 passing through the clamping arm 43, and the guide rod 42 being configured to limit the movement trajectory of the clamping arm 43; and a support rod 41, which is fixedly connected to the guide rod 42, the support rod 41 being located between the template 431 and the guide rod 42, the top of the support rod 41 abutting against the clamping arm 43, and the support rod 41 being configured to support the clamping arm 43.

[0038] like Figure 1 and Figure 2 As shown, each clamping arm 43 has a guide hole at its rear end, and a guide rod 42 passes through two guide holes, so that the rear ends of both clamping arms 43 are fitted onto the guide rod 42. A support rod 41 is located at the front end of the guide rod 42 and is connected to the guide rod 42 via a connecting rod 46. The bottom of the clamping arm 43 overlaps the upper part of the support rod 41. Thus, when the two clamping units open and close, the clamping arms 43 can move along a preset trajectory under the constraint of the guide rod 42, thereby making the placement of the template 431 more accurate. At the same time, since the support rod 41 is located between the guide rod 42 and the template 431, it can effectively support the clamping arms 43 from below, preventing the clamping arms 43 and the front template 431 from tilting forward due to gravity, ensuring the structural stability of the clamping unit under opening, closing and load-bearing conditions.

[0039] In some specific embodiments of the present invention, the main groove includes two first main grooves 11 and two second main grooves 12 that are arranged opposite to each other and extend in the vertical direction. The branch groove includes a plurality of first branch grooves 111 that are distributed vertically at intervals and all intersect and communicate with the first main grooves 11, and a plurality of second branch grooves 121 that are distributed vertically at intervals and intersect and communicate with the second main grooves 12. The first branch grooves 111 and the second branch grooves 121 both extend in the horizontal direction. The lifting mechanism 2 can drive the support rod 41 to slide along the first main groove 11 to the intersection of the first main groove 11 and one of the first branch grooves 111, and drive the guide rod 42 to slide along the second main groove 12 to the intersection of the second main groove 12 and one of the second branch grooves 121. The pushing mechanism 3 can drive the support rod 41 to slide from the intersection of the first main groove 11 and one of the first branch grooves 111 into one of the first branch grooves 111, and drive the guide rod 42 to slide from the intersection of the second main groove 12 and one of the second branch grooves 121 into one of the second branch grooves 121.

[0040] like Figure 1As shown, the frame 1 has two first main slots 11 and two second main slots 12 that are arranged opposite each other and extend vertically. Specifically, the two first main slots 11 are located in front of the two second main slots 12; the two first main slots 11 are respectively arranged on the left and right sides of the frame 1 and are symmetrical to each other, and the two second main slots 12 are also respectively arranged on the left and right sides of the frame 1 and are symmetrical to each other. The first main slots 11 have a plurality of first branch slots 111 that are evenly distributed vertically and extend forward horizontally; the second main slots 12 have a plurality of second branch slots 121 that are evenly distributed vertically and extend forward horizontally. During operation, the lifting mechanism 2 drives the support rod 41 to slide along the first main groove 11 to its intersection with the target first branch groove 111, and simultaneously drives the guide rod 42 to slide along the second main groove 12 to its intersection with the target second branch groove 121. Subsequently, the pushing mechanism 3 drives the support rod 41 to slide from the intersection into the corresponding first branch groove 111, and simultaneously drives the guide rod 42 to slide from the intersection into the corresponding second branch groove 121. Under the sequential drive of the lifting mechanism 2 and the pushing mechanism 3, the support rods 41 of the multiple clamping modules 4 slide one by one into each first branch groove 111, and their guide rods 42 slide one by one into each second branch groove 121, thereby allowing the clamping units of the multiple clamping modules 4 to be sequentially spliced ​​from top to bottom in the vertical direction to form a complete mold cavity to be poured.

[0041] In some specific embodiments of the present invention, the two clamping arms 43 are rotatably connected, and an arc-shaped part 421 is provided on the guide rod 42. The arc-shaped part 421 passes through the clamping arm 43, and the curvature of the arc-shaped part 421 is adapted to the motion trajectory of the two clamping arms 43 when they rotate relative to each other.

[0042] like Figure 2 As shown, the two clamping arms 43 are hinged together. Specifically, the template 431 is L-shaped, having a main plate extending in the front-to-back direction and a web plate perpendicular to the main plate and connected to its rear end. The hinge between the two clamping arms 43 is located between the two web plates. The guide rod 42 is provided with an arc-shaped portion 421, which is located at the connection between the clamping arm 43 and the guide rod 42. The curvature of the arc-shaped portion 421 is adapted to the movement trajectory of the two clamping arms 43 when they rotate relative to each other, so as to ensure that the clamping arms 43 can slide smoothly along the preset path during opening and closing, avoiding jamming.

[0043] In some specific embodiments of the present invention, the structural form of the guide rod 42 can be designed in various ways according to the processing technology and assembly requirements. Specifically, in some embodiments, the guide rod 42 is entirely arc-shaped, that is, it is continuously curved from one end to the other, and the arc-shaped portion 421 covers the entire guide rod 42. This structural form is simple to process, has high motion guidance accuracy, and requires the guide hole at the rear end of the clamping arm 43 to pass through one end of the guide rod 42 during assembly. It is suitable for assembly scenarios where the clamping arm 43 can be pre-fitted onto the guide rod 42.

[0044] In other implementations, such as Figure 2 and Figure 3 As shown, to facilitate the assembly or replacement of the clamping arm 43, the guide rod 42 includes straight sections 422 at both ends and an arc-shaped section 421 in the middle. The straight sections 422 extend horizontally, and the arc-shaped section 421 connects the two straight sections 422. In this structure, since the axial directions of the straight sections 422 and the arc-shaped section 421 are different, the guide hole at the rear end of the clamping arm 43 cannot directly pass through the straight section 422 and slide to the arc-shaped section 421. As an optional embodiment, the straight section 422 and the arc-shaped section 421 are detachably connected. Specifically, the straight section 422 is of the broken line type, which includes a straight segment and an arc-shaped segment that can connect with the arc-shaped section 421. One end of the arc-shaped segment is provided with an external thread, and both ends of the arc-shaped section 421 are provided with matching internal threads. The two are fixed by threaded connection. During assembly, the guide hole of the clamping arm 43 can be first fitted onto the arc-shaped part 421, and then the straight part 422 can be screwed into both ends of the arc-shaped part 421 to achieve the overall assembly of the guide rod 42. As another optional embodiment, the arc-shaped part 421 adopts a split structure, that is, the arc-shaped part 421 includes a first half-shell and a second half-shell that are separated into two halves, which are detachably connected by bolts, snap-fits, or hinges. During assembly, the first half-shell and the second half-shell can be opened first, the clamping arm 43 can be fitted into a predetermined position, and then the first half-shell and the second half-shell can be closed and fixed, thereby fitting the clamping arm 43 onto the guide rod 42. As yet another optional embodiment, the guide hole at the rear end of the clamping arm 43 itself adopts an openable and closable structure. Specifically, the guide hole includes a fixed part and a movable part, the movable part being connected to the fixed part by a hinge or snap-fit, and can be opened or closed relative to each other. During assembly, open the movable part, insert the guide hole into the predetermined position of the guide rod 42, then close and lock the movable part to achieve the sleeve connection between the clamping arm 43 and the guide rod 42. The above-mentioned structural designs ensure that the template device of this embodiment guarantees guiding accuracy while also considering ease of assembly and flexibility of maintenance, allowing for selection based on different production conditions and construction needs.

[0045] In some specific embodiments of the present invention, the propulsion mechanism 3 and the guide rod 42 are detachably connected.

[0046] like Figure 1 and Figure 3As shown, the propulsion mechanism 3 has a connecting part on the side facing the guide rod 42, and a first connecting hole is provided on the connecting part; a second connecting hole is provided on the guide rod 42 at a corresponding position. When the connecting part is connected to the guide rod 42, the first connecting hole and the second connecting hole are aligned with each other, and the pin is inserted into the first connecting hole and the second connecting hole, thereby realizing the fixed connection between the propulsion mechanism 3 and the guide rod 42. After the pin is inserted, the propulsion mechanism 3 can transmit thrust to the guide rod 42 through the pin, driving the guide rod 42 to move forward along the second main groove 12, thereby driving the entire clamping module 4 to move to the pouring position. After the clamping module 4 is in place and locked in the first branch groove 111 and the second branch groove 121, the pin is pulled out from the first connecting hole and the second connecting hole, thereby realizing the separation of the propulsion mechanism 3 and the guide rod 42. Then the propulsion mechanism 3 can be lowered and reset with the lifting mechanism 2 to install the next clamping module 4.

[0047] As an optional implementation, the pin can adopt a resilient pin structure with an internal spring. When the connecting part mates with the guide rod 42, the pin is compressed and retracts; when the first connecting hole aligns with the second connecting hole, the spring drives the pin to automatically pop out and insert into the hole, achieving automatic connection. When separation is required, the pin can be pulled out manually or mechanically. This resilient pin structure enables rapid docking and separation of the pushing mechanism 3 and the guide rod 42, further improving construction efficiency.

[0048] Furthermore, the pin can be electrically or pneumatically driven, and the insertion and removal of the pin can be automatically controlled by the control system to achieve complete automation of the connection between the propulsion mechanism 3 and the guide rod 42.

[0049] In some specific embodiments of the present invention, the clamping module 4 further includes a limiting component 45, which is disposed on the clamping arm 43 and is configured to restrict the clamping arm 43 from moving backward after it moves to the pouring position.

[0050] It should be noted that "moving backward" refers to moving towards the direction of the propulsion mechanism 3, that is, away from the direction of the poured wall. During the slurry pouring process, a huge lateral pressure is generated inside the mold cavity. This lateral pressure tends to push the clamping arm 43 backward, causing misalignment of the mold. The function of the limiting component 45 is to resist this lateral pressure, lock the clamping arm 43 in the pouring position, and ensure that the mold maintains a precise position during the slurry solidification process, thereby ensuring the forming dimensions and verticality of the wall.

[0051] In some specific embodiments of the present invention, the limiting component 45 includes: a limiting pin 451, which is disposed at one end of the clamping arm 43 near the frame 1; and a limiting groove 452, which is formed on the frame 1. The limiting groove 452 is adapted to the limiting pin 451. When the clamping arm 43 moves to the pouring position, the limiting pin 451 is inserted into the limiting groove 452.

[0052] like Figure 1 As shown, the limiting pin 451 is fixedly connected to the rear of the clamping arm 43 and extends towards the frame 1. A limiting groove 452 is formed on the frame 1, its position corresponding to the limiting pin 451, and its size and shape are adapted to the limiting pin 451 so that the limiting pin 451 can be inserted into the limiting groove 452. When the clamping module 4 moves forward to the pouring position under the drive of the propulsion mechanism 3, the limiting pin 451 moves forward accordingly. When the clamping module 4 is fully in place, the support rod 41 engages with the first branch groove 111 at the corresponding height, the guide rod 42 engages with the second branch groove 121 at the corresponding height, and the limiting pin 451 is precisely inserted into the limiting groove 452, thereby locking the clamping arm 43 to the frame 1 and preventing the clamping arm 43 from moving backward.

[0053] As an optional implementation, the limiting pin 451 is an elastic telescopic pin with a spring inside. When the clamping module 4 moves forward, the limiting pin 451 is compressed by the frame 1 and retracts; when it moves to the position of the limiting groove 452, the spring drives the limiting pin 451 to automatically pop out and insert into the limiting groove 452. This elastic telescopic structure can realize the automatic locking of the limiting pin 451 without manual operation, thus improving construction efficiency.

[0054] In other specific embodiments of the present invention, such as Figure 4 As shown, a guide plate 13 is vertically mounted on the frame 1, and a first main groove 111 is opened along the length of the guide plate 13. Two limiting pins 451 are spaced apart in the front-to-back direction. When the clamping module 4 moves forward to the pouring position under the drive of the propulsion mechanism 3, both limiting pins 451 extend simultaneously. The front limiting pin 451 abuts against the front end face of the guide plate 13 to restrict the clamping arm 43 from moving backward; the rear limiting pin 451 abuts against the rear end face of the guide plate 13 to restrict the clamping arm 43 from moving forward. Through this structure of front and rear double limiting pins, the clamping arm 43 can be locked simultaneously in both front and back directions, effectively preventing the clamping module 4 from shifting forward or backward due to lateral pressure or vibration during slurry pouring, further improving the stability of the template and the pouring accuracy.

[0055] Of course, the limiting component 45 can adopt a simpler structure, eliminating the need for a dedicated limiting groove 452 on the frame 1. Specifically, the limiting pin 451 is located at the end of the clamping arm 43 near the frame 1 and extends towards the frame 1. The front end face of the frame 1 is set as a flat stop surface. When the clamping module 4 is fully in place, the front end of the limiting pin 451 abuts against the front end face of the frame 1, thereby restricting the clamping arm 43 from moving forward further.

[0056] It should be noted that when the pouring is completed and the formwork 431 needs to be removed, the limiting pin 451 can be pulled out of the limiting groove 452 manually or mechanically to release the lock. Then, the clamping module 4 can be moved backward and lowered for retraction. The locking and unlocking methods of the limiting pin 451 are conventional technologies in this field and will not be described in detail here.

[0057] In some specific embodiments of the present invention, grouting holes 4311 are provided on the template 431. For example... Figure 2 As shown, the grouting hole 4311 is located on the side of the mold, penetrates the wall thickness of the mold, and is connected to the mold cavity formed after the two molds are closed. It can also be connected to the grout conveying pipeline to realize lateral pressure casting.

[0058] Specifically, multiple grouting holes 4311 can be provided, and these holes 4311 are spaced apart along the length of the mold. The design of multiple grouting holes 4311 can be selected according to the wall height and grout flowability. For example, when casting a tall wall, multiple grouting holes 4311 can be opened simultaneously for layered casting to ensure that the grout can evenly fill the entire mold cavity and avoid segregation or void defects caused by excessive casting height. To further improve the casting quality, an openable and closable sealing cap can also be installed at the grouting hole 4311. During the casting process, the sealing cap is opened to allow grouting; when casting is completed or paused, the sealing cap is closed to prevent grout backflow or overflow in the mold cavity, and to prevent debris from falling into the mold cavity.

[0059] In some specific embodiments of the present invention, the lifting mechanism 2 includes: a lifting drive assembly 21, which is mounted on the frame 1; a lifting platform 22, which is mounted at the output end of the lifting drive assembly 21, and the lifting platform 22 is configured to support the clamping arm 43; and a support member 23, which is mounted at the front end of the lifting platform 22, and the support member 23 abuts against the bottom of the clamping arm 43, and the support member 23 is configured to prevent the clamping arm 43 from tipping downward during the lifting process.

[0060] like Figure 1As shown, the lifting drive assembly 21 is mounted on the frame 1 and provides lifting power. The lifting platform 22 is located at the output end of the lifting drive assembly 21. The upper surface of the lifting platform 22 supports the support rod 41 of the clamping module 4. When the support rod 41 and the guide rod 42 are detachably connected to the output end of the lifting mechanism 2, the support rod 41 is supported on the lifting platform 22, which provides vertical support. The support member 23 is located at the front end of the lifting platform 22, facing the clamping module 4. The support member 23 extends forward and abuts against the bottom of the clamping arm 43. During the process of the lifting mechanism 2 driving the clamping module 4 to rise or fall, the center of gravity of the clamping module 4 may shift forward due to the cantilever structure of the clamping arm 43, causing the clamping arm 43 to tend to tilt forward and downward. The function of the support member 23 is to support the clamping arm 43 from the bottom, providing auxiliary support for the clamping arm 43, thereby preventing it from tilting or swaying downward due to the shift in the center of gravity during the lifting process. When the propulsion mechanism 3 drives the clamping module 4 to move forward, the clamping arm 43 gradually moves away from the support range of the support member 23. At this time, the load of the clamping module 4 has been transferred to the support rod 41 and the guide rod 42, and is borne by the first branch groove 111 and the second branch groove 121. Therefore, the support member 23 does not need to continue to provide support.

[0061] As an optional implementation, the support 23 can be configured as a roller or slider structure, so that when the clamping arm 43 moves back and forth relative to the lifting platform 22, the support 23 can roll or slide in contact with the bottom of the clamping arm 43, providing support without interfering with the horizontal movement of the clamping arm 43. As another optional implementation, the height of the support 23 can be adjustable, allowing for fine-tuning according to the height position of the clamping arm 43, ensuring that the support 23 always maintains effective contact with the bottom of the clamping arm 43. Thus, by setting the support 23, this embodiment effectively solves the stability problem of the clamping module 4 during the lifting process, avoiding the risk of center of gravity shift and overturning caused by excessive overhang of the clamping arm 43, and ensuring the stability and safety of the clamping module 4 during the lifting process.

[0062] The following describes in detail the construction method of the automatic clamping grout pouring formwork device provided in this embodiment, taking the case where at least one end of the infill wall is connected to a column or an existing wall as an example.

[0063] S1: Determine the specifications and quantity of the required clamping modules 4 based on the design dimensions of the wall to be poured.

[0064] S2: Move the frame 1 to the wall to be poured, adjust the position of the frame 1 so that the front end of the frame 1 is aligned with the designed position of the wall and is parallel to the column or existing wall.

[0065] S3: Assemble the uppermost clamping module 4 on the lifting platform 22. Specifically, embed both ends of the support rod 41 into the two first main slots 11, and place the support rod 41 on the lifting platform 22. Fit the guide holes at the rear ends of the two clamping arms 43 onto the guide rod 42, and embed both ends of the guide rod 42 into the two second main slots 12. Fix the guide rod 42 and the support rod 41 together through the connecting rod 46. At this time, the two clamping arms 43 are in the closed state, and their front mold-closing ends are in contact with each other.

[0066] S4: Install the opening and closing drive assembly 44 between the two clamping arms 43, install the propulsion mechanism 3 on the frame 1 so that it can slide in the vertical direction, and ensure that the connecting part of the propulsion mechanism 3 can be connected with the guide rod 42.

[0067] S5: Connect the connecting part of the propulsion mechanism 3 to the guide rod 42, operate the automatic control system, start the lifting mechanism 2, and drive the lifting platform 22 to rise. The lifting platform 22 supports the support rod 41, driving the entire clamping module 4 to rise vertically along the first main groove 11 and the second main groove 12 until it reaches the preset height corresponding to the uppermost cavity. During the rising process, the propulsion mechanism 3 rises and falls synchronously with the lifting mechanism 2 to prepare for subsequent docking.

[0068] S6: After the clamping module 4 rises to the preset height, the automatic control system is activated, and the propulsion mechanism 3 is started, driving the guide rod 42 to move forward along the second main groove 12. Simultaneously, the guide rod 42 moves forward, driving the support rod 41 to move forward synchronously along the first main groove 11 via the connecting rod 46, thereby moving the entire clamping module 4 forward until the limiting pin 451 at the rear end of the clamping arm 43 is inserted into the limiting groove 452. At this time, the support rod 41 is engaged in the first branch groove 111 at the corresponding height, and the guide rod 42 is engaged in the second branch groove 121 at the corresponding height. The load of the clamping module 4 is transferred from the lifting mechanism 2 to the branch grooves.

[0069] S7: Separate the connecting part of the propulsion mechanism 3 from the guide rod 42, operate the automatic control system, and lower the propulsion mechanism 3 to the bottom along with the lifting mechanism 2 to prepare for the installation of the next clamping module 4.

[0070] S8: Repeat steps S3 to S7 above, and install each layer of clamping module 4 from top to bottom in sequence to finally form a complete wall cavity system.

[0071] S9: After all clamping modules 4 are installed, make minor adjustments to the position of the frame 1 to ensure that the closing of each layer of clamping modules 4 coincides with the design edge line of the wall to be poured. Check whether each limit pin 451 is in place and whether each branch slot is securely fastened.

[0072] S10: Grout is poured into the mold cavity through the grouting hole 4311 on the mold. During the pouring process, grout can be poured in layers or all layers can be poured at the same time as needed.

[0073] S11: After the slurry has solidified and reached the demolding strength, begin removing the formwork 431 from bottom to top. Specifically, release the locking pin 451 on the clamping module 4, start the lifting mechanism 2, drive the lifting platform 22 to rise to the height of the clamping module 4 at this level, and reconnect the connecting part of the pushing mechanism 3 with the guide rod 42; start the opening and closing drive assembly 44, drive the two clamping arms 43 to open, so that the mold is separated from the poured wall; start the pushing mechanism 3, drive the guide rod 42 to move backward, pull the support rod 41 and the guide rod 42 out of the branch groove, and move them backward along the main groove to the side close to the frame 1; start the lifting mechanism 2, drive the lifting platform 22 to descend, and lower the clamping module 4 at this level to the ground; disassemble the clamping module 4 on the ground, and disassemble and recycle the clamping arms 43, mold, support rod 41, guide rod 42 and other components for reuse.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
